The electric machinery type selecting of channel kiln is intelligence converts tile plant infrastructure acquires successful important segment, electric machinery type selecting suits, project investment is little, amount to produce fast, product quality is smooth, asset is bought fast; Contrary, project investment is large, do not have a law for a long time to amount to produce, commodity is unqualified, asset buys hardship, and even give to compare serious lose money in business. In channel kiln in development trend whole process of nearly 20 years, the typical sex that acquires successful project investment a lot of, but rear example also without number.
The channel kiln that what chooses is really investor to wisdom person the person that see Zhi Ren sees benevolence important step, what had better channel kiln be? The authoritative expert inside tile production industry each are not identical, did not make conclusions, those who have cross section of some of National People's Congress is good, those who have some of person little cross section is good, cause investor to lose one's head. So that a lot of people are intense the kiln furnace that recommends oneself or so that the rights and interests of oneself recommends relevant kiln furnace strongly,be, the article is published on print of books and newspaper and Internet, beneficial to oneself do his utmost national creed, 4 good, months amount to project investment little effect produce, it is daily how much be 10 thousand these, derogate other kiln furnace of purpose, also be in must the effect that horizontal place had promiscuous seeing and hearing. The working experience with below very old confluence understands the advantage of various channel kiln and weakness, pick way for what investor produces a fair justice.
One, vault kiln will be replaced by slope housetop kiln gradually
Slope housetop kiln replaces the development direction that is to say of brickkiln vault kiln. From anatomical the safety factor that says vault kiln should compare slope housetop kiln to differ a lot of. Upend active force presses the suttle and only basis with slope housetop entire pit in kiln wall, do not have force of pedal having side to kiln wall; And vault kiln its kiln is very suttle with upend active force and side pedal effect of 2 kinds of strength is in force kiln wall, be kiln of small push without using one's hands especially, its arch is tall (tall or arrow is black tall) smaller, the pedal power that kiln carries pair of both sides on the head is greater. So that balance be forced to do increases power of pedal of this a side thick model kiln wall or column of promotion structure consolidate, prevent kiln wall crack or collapse.
Vault kiln has a greater difficult problem in other words to do not have a law to maintain specialization production is made, as a result of base battlements the machine of base of one part code of the broaden intermediate does not have law group group. A lot of people used the method of half mechanization, that is to say slants a line is following one part has been piled up with the machine that pile up base, one part reoccupy serves broaden artificially above code, solve capital of great majority manpower thoroughly in that way.
So that a lot of people handle vault kiln specialization the difficult problem that pile up base, slant kiln top an one part press paragraph of keep out with fireproof insulation material (block igneous board) , normally a parking space blocks, but meet in that way extravagant waste gives out heat for the most part quantity, and if destroy,block igneous board tear open change very disadvantageous, this also is expedient only. From long-term seeing Zuo is paper-cover it is good that long condole carries safety factor on the head.
2, the development direction that kiln of channel of large cross section is tile production industry
The in be cross section that weighs kiln of 3.6-4.6 rice channel temporarily according to the chronic people inside production industry, 6.9 meters or so say for large cross section, 3.6 meters say followingly for little cross section.
Channel kiln cross section is larger, its height is smaller, because this issues or so temperature on its,difference is jumped over small, product quality is smoother. Kiln of channel of Chinese large cross section designs conception accident normally 140 meters or so, some and even more than 180 meters, earth up in that way burn grow between , commodity compressive strength is high, be in especially suit to burn make high-end goods. Want to promote tile product quality in our country consequently, be sure to base oneself upon at developing kiln of channel of trend large cross section. British tile makes kiln of channel of industry great majority is 9.5 meters of cross section completely.
But some closer rate of year of trend of development of kiln of channel of large cross section is slower, crucial cause is a project investment is very large, amount to produce hardship. Some authoritative experts and even denied thoroughly consequently kiln of channel of large cross section, a lot of investor are be terrified by the sight of sth or sb to kiln of channel of large cross section. Bring about both neither of this kind of condition to be able to run the authoritative expert that boycotts a proposal with ascribing to thoroughly in fact, also can not blame investor.
Show level to although promote the national level of fired brick the standard repeatedly,adorn a profession, but execute on the spot very hard however, adorning a profession is extremely low to the formulary Zuo of product quality, a few district and even it is to make up chaos to build why, defective canal accuses. This kind shows besides one part cause is to build an industry to be eager to work skill, without try quality, another project building that follows in our country has quite big correlation chronically, wall body 90% the left and right sides is the skin that daub a wall completely. Again much fired brick was obscured by wall skin also cannot see, owner of a few villages lived a lot of years building and even the what brick that never has seen base wall is used, also make much person pay close attention to this one difficult problem rarely, accordingly estate business, bear which kinds of brick that builds business to also become aware does not care completely. In that way the driving force that tile factory did not have promotion product quality, high quality not only promoted manufacturing production difficulty coefficient, also promoted a product cost together, because this makes an industry take horizontal inadequacy seriously to product quality height in tile, in the light of tile factory character, if can sell a that is to say good goods. Consequently the advantage of kiln of channel of large cross section does not go out with respect to report, this also was kiln of channel of development trend large cross section to produce quite big hardship.
Kiln of channel of large cross section is more backward, design a section ought to difficult demit its blame. Kiln of channel of little cross section a lot of advantages are completely last in very old practice activity hunting, brief summary innovates independently go out, but the development that kiln of channel of large cross section is here two years did not have in the trend is how many own innovation, outside having constant change except the accident that opens pit, aspect ratio that pile up base, other level foundation is changeless.
It is good that energy-saving nucleus psychology reads aloud the increase production of kiln of channel of large cross section, environmental protection, but the advantage that does not have report to give it from beginning to end however when actual design is conceived, detect from inside practice activity of these two years, kiln of channel of large cross section is amounted to produce hardship, it is more difficult to overfulfill, and kiln of channel of little cross section is easy as my eyes can amount to produce, it is very easy also to overfulfill. The advantage with energy-saving environmental protection of kiln of channel of large cross section goes out without report, show level great majority to send quantity of heat to be met 400 calorie are controlled, and what kiln of channel of little cross section sends quantity of heat to exceed 400 calorie is very scarce, great majority is among 300-400 calorie. This that is to say why some closer go no further of year of trend of development of kiln of channel of large cross section not the crucial cause before. Should develop kiln of channel of trend large cross section consequently shoulder heavy responsibilities, must hall of the colleague inside course of study struggles jointly, its increase production, environmental protection energy-saving good point is real show. If total output of kiln of 6.9 meters of channel can capture 90 million, calorific quantity can operate fluctuate in 360 calorie, sale popularizes difficulty coefficient is not easy that Zuo is big, gain ground it is very easy also to change.
3, kiln of channel of little cross section is to transfer model
Low, design conceives cost of kiln of channel of little cross section per unit area yield is high, amount to produce faster, because this achieves a lot of sale inside production industry,popularize. It is with 3.6 meters exemple, design conception per unit area yield can exceed 4000-5000 10 thousand, total output of every meters of cross section exceeds 1100-1400 10 thousand, output of cross section of kiln of channel of comparative large cross section can promote 25-60% , consequently a few professional personages design a company nowadays also very the conceive large cross section from the design and turns to kiln of channel of little cross section design conception of not reconciled to. This kind of not reconciled to is the have no alternative of this kind of passive type, it is the Jian fruit that sells market leverage, as a result of these year of practice experience the advantage of kiln of channel of little cross section. The low character that lives in building materials market also develops a tendency from what additionally the level drove kiln of channel of little cross section.
No matter look from which perspective, kiln of two 3.6 meters of channel must compare this 6.9 meters project investment is high, and cover an area of a face accumulate big, equipment of kiln furnace moving machine and purifying device are much, charge of electricity of the water in machining a process, upkeep costs must compare this 6.9 meters tall a lot of, but basically majority investor chose two 3.6 meters, and do not choose this 6.9 meters. I want investment to yield leading this one main parameter is the crucial ground that investor chooses kiln of channel of little cross section.
How does kiln of channel of Dan Xiaoheng section develop a trend to count only no matter this kind joins kiln, investor is right of kiln of channel of little cross section the measure that choosing is this kind of have no alternative only, if the good point of kiln of channel of large cross section is real,show, kiln of channel of little cross section will fall into disuse.
Some closer the development trend of kiln of year of channel of little cross section a little the confused look of be there just to make up the number, a lot of small kiln furnace companies go with high production of small project cost for banner, constructed the channel pit with a lot of poor quality. Not only output is not amounted to on expect the result, and quality of can tall, product needs waste time, security of kiln furnace oneself did not ensure. This is a bitter pill to swallow that investor goes after small fund one-sidedly to throw high yield to give generation.
4, carbonado type channel kiln must be improved continuously
Carbonado continuously type channel kiln (carbonado burn unifinication kiln) design conception is good, arrive from airing earth up burn enter continuously go out continuously, reduced middleman, dropped machine device, managing farm. But become a kiln can every centrifugal fan, desiccate dry pit is entire all going air pressure circumstance, this makes dry impetuous of the bottom in base battlements not quite good with respect to what avoid hard, be in especially more remarkable in the winter, light a crack, the condition pours base badly. The real operation standard of oast is: Ultralow temperature, wind is many, small pressure. Small the eye ground of pressure is the precision that handles dry impetuous, can arise in below oast half part only namely small pressure can make dry impetuous of total base battlements well-balanced. Because the front that earths up kiln is in very big air pressure case, and the provision of below half section of oast is in small pressure circumstance, mix oast cultivating the connection with simple and easy kiln is to do not have a law to handle this one divergent together. A lot of people are burned in Duan Hepei doing impetuous paragraph hand in collect place promotion centrifugal fan, can raise dry impetuous greatly in that way practical effect, but it is difficult to have many sided was not solved.
Carbonado type channel kiln passes continuously short can bring about commodity undersintering, some carbonadoes channel kiln commodity just entered tall warm temperate zone to did not have all previous to enter water cooling zone instantly via adiabatic heat preservation continuously, bring about commodity dumb sound, some finished products bricks are compared without fine serious, surface layer is burned only appeared 3-5mm, the essence intermediate did not have burn fully, if use plasticity to be out of shape poor gangue brick or diabase make raw material, this kind of brick sees water with respect to delamination, did not have compressive strength constitutionally.
Carbonado continuously if type channel kiln can not develop first-rate improvement, what if can not obtain first-rate processing,relate difficult problem, future will label the team that defeats commodity very much.
5, portable channel kiln must be sought again
Portable channel kiln is some closer year this kind of new cave dwelling that develops trend take shape before long. As a result of its need not kiln car and kiln furnace run machine facility and managing one part project invests, because this is opposite,certain small and medium sized business has allure very much. But portable channel kiln also has had difficult problem, must handle gradually in seek:
1, kiln furnace must the annular place of straight 80-120 rice, place of the great majority intermediate can be not applied, luxury wasted farm; 2, centralized smoke evacuation system and difficult problem of to decoke of centralized flue gas still do not have first-rate processing; 3, because kiln heat is daily the metropolis is ceaseless in mobile, to its accordingly compressive strength and service life often have quite great harm, overall service life and Zuo of kiln of movable type channel can be not compared, must seek improvement again.
