Roller path kiln is the large facility heating up labour with firing goods of floor tile of wall of pottery and porcelain. According to pottery and porcelain firing technology is sound the roller path kiln after the design, make through treatment, installation construction throws actual test-drive phase, enter next produce normally. Whether in reflecting design intent of the architect well and truly actual production, make roller path kiln seasonable, throw reasonably move, amount to at an early date produce add close, each paragraphs of the treatment of roller path kiln that make, working procedure that installs construction and technical parameter appear very important.
The treatment of roller path kiln is made reach measure of sue for peace of installation construction technology to narrate level technology requirement
Because roller,structure of kiln kiln system is section modulus assembly type, the thermal stress of the frame when soldering is out of shape is hard to avoid. And the stand or fall of quality of frame of furnace of kiln of this paragraph of working procedure goes to immediate impact below a series of working procedure, affect the kiln furnace in the future even whether use reach service life accident. Because this controls each technical parameter strictly,assure to solder each structural dimension undertakes strictly by blueprint. Want to control following technical parameter strictly so: (1) assures pillar span (namely center of pillar roller aperture is apart from) : ≤ ± 1.0mm; (2) assures error of level of center of pillar roller aperture: ≤ ± 0.5mm; (3) makes sure pillar roller aperture is diagonal: ≤ ± 2.0mm; (4) assures size of pillar roller hole: 1.0mm of fluctuation ≤ ± , or so ≤ 0.5 ± Mm; (5) assures on size error of modulus of kiln body frame: ≤ ± 2.0mm; (6) makes sure kiln wears whole to reduce knot surplus to be: ≤ ± 15mm.
Kiln furnace frame installs measure and technical requirement
Carry of the frame outside making ending kiln oven according to afore-mentioned parameter arrives after construction site, enter frame to install level (of course, according to particular case, also can build kiln furnace build by laying bricks or stones butt joint of construction building site is pulled to install) after ending. This is the kiln wearing working procedure that make is outspread, also be setup of system of next each wind, report, oil path and fireproof material build by laying bricks or stones to build prepare the job. Press construction order, enter from frame before assembling, whether does each index obtain close check above technical requirement of the regulation, be like short of, should have the corrective job of frame. Before installation, still check kiln furnace foundation reasonable, include: Bear load ability, horizontal error should be controlled inside limits of ≤ ± 10.0mm.
Each working procedure checks above end, enter the process that put a line. Determine position of kiln furnace center according to craft blueprint cardinal principle, error control is in ≤ ± 10.0mm (namely the center arrives between workshop pillar or wall center line distance) . After central position is firm, reach kiln furnace frame from the beginning end is ordinal arrange reach the designated position, affirmatory roller center arrives fiducial reference point of the foundation, in pile of kiln furnace around, pull steel wire to regard kiln furnace center as the line, it is line of standard center of kiln furnace frame with transmission center certainly, undertake with sruveyor's level the fixed position of each frame adjusts. Adjust control dimension is: (1) is kiln furnace center with steel wire, when adjusting each frame center and steel wire deviation: ≤ ± 1.5mm; (Center of the pillar between frame of body of 2) each kiln is apart from deviation: ≤ ± 1.0mm; (3) and affirmatory referenced datum mark are compared, error of transmission center level: ≤ ± 1.5mm. By 3 afore-mentioned technologies index adjustment is over after frame of each kiln furnace, comprehensive examination after be being made again, issue the on the rails of working procedure in order to ensure.
Setup of mechanical transmission system reachs a requirement
Transmission system is helical gear drive, this system includes bearing of device of drive electric machinery, decelerate, helical gear, oil groove and roller club. After step of brick of kiln furnace aperture is good, can have the setup of transmission system. Of course, want to be able to assure 1.0mm of ± of ≤ of error of horizontal of horizontal of aperture of aperture brick center and transmission roller great center only, also can build section of a construction project at kiln furnace build by laying bricks or stones independently. But anyhow, can install kiln furnace pillar to go up beforehand advocate, driven bearing just is in charge of, because eventually advocate, driven bearing piece and backing plate and fixed prop up can fluctuate between square canal adjust, in order to assure the standard of transmission. Installation is fine prop up square canal, undertake carrying the installation of bearing piece and backing plate and inclined tine actively, it is of driven end again next the installation of bearing piece, backing plate and roller marvellous driven pulley.

4, heat preservation of kiln furnace conduit
The build by laying bricks or stones of kiln furnace builds the heat preservation project that still includes each wind valve. Conduit heat preservation basically is to show warm-up belt and cooling zone smoke a sirocco, flue gas to have the thermal insulation of the canal of this paragraph of wind of body drying to desiccator, the purpose is to decrease medicinal powder hot, assure to enter the aeriform temperature of oast to be controlled in 300 ℃ . Heat preservation of this paragraph of conduit, be heat preservation cotton (it is common and siliceous aluminium comes loose commonly cotton) bind after going up, outer layer laps an aluminous skin or stannic platinic paper. The key of conduit heat preservation is outside decorate a layer pack, requirement level off, beautiful, the worker operation that needs adroitness is finished. This working procedure solders conduit end and be certainly below the circumstance that does not have air leak phenomenon only reentry goes.
Installation of accessory equipment, conduit reachs other requirement
Accessory equipment includes from beginning to end fan of two platform, each model. Conduit includes each wind canal, vitta, tracheal, conduit to wait. After kiln furnace frame locates, while fireproof material build by laying bricks or stones builds kiln furnace, can undertake platform solders, all sorts of conduit solder installation, can build across to install construction with fireproof material build by laying bricks or stones. This working procedure should solder from platform first begin. Because platform is the foundation of each fan, dead load bears already above, must bear again in the future of each fan move load. Accordingly, installation solders when platform, should ensure foundation is firm and smooth, make sure design size is exact, make sure platform is stable, solder contact is beautiful. The counterpoint that is each wind canal next solders installation, each wind canal basically includes kiln head smoke evacuation, platoon wet be in charge of with circular wind, firing place of belt, urgent cold belt supports combustion each canal of canal of wind of smoke of the wind canal, pulverization wind canal, heat that take a platoon, urgent air cooling. Wind canal installation is commonly orderly from advocate wind is in charge of the canal that raise wind. Wind is in charge of solder requirement not air leak, design dimension strictly to undertake by blueprint.
Additional, because pulverization fan is independent at kiln body, besides park workshop, so pulverization wind canal can be put from the back undertake together with pipeline of oil path system. Also can undertake at the same time, inspect the site actual condition and calm, but should make sure wind is in charge of not air leak. Next hoisting each fan, want to notice the model of each fan right now, with each wind conduit join ends later. All wind are in charge of installation and with fan UniCom hind, installation joins the cooling water on corresponding fan is in charge of, position of cooling conduit dimension depends on spot circumstance and combinative blueprint undertakes installing. Of course, according to the spot actual condition, each measure can master above neatly. All and accessory equipment and the technical requirement that conduit installs are (when 1) solders air leak of strict guarantee against, slack. Each fan quality guards a pass strictly, especially pulverization fan () of Luo Ci fan.
