Description
Technical field
The utility model relates to a kind of cooling machine parts, especially a kind of cooling machine grate plate, specifically a kind of grid plate of energy-saving grid cold machine.
Background technology
As everyone knows, grate plate is the core component of grate cooler, and the structure of existing grate plate is comparatively simple, and the cross section of its air outlet mostly is square structure greatly, is easy to by grog stuckly, and makes cooling see and can't infiltrate in the bed of material, easily causes the grate plate scaling loss.Be not easy to produce owing to stopping accordingly between the simultaneously relative air-out wind gap, cooling effect is descended, therefore must be improved, with the energy-saving effect of further raising cooling machine to blowing backflow phenomenon.
Summary of the invention
The purpose of this utility model is simple in structure at existing grate plate, and easily scaling loss and the relatively poor problem of cooling effect design a kind of grid plate of energy-saving grid cold machine.
The technical solution of the utility model is:
A kind of grid plate of energy-saving grid cold machine, comprise the chassis, the bottom on chassis is provided with air inlet, it is characterized in that described chassis 1 relative dual-side all is connected with elder generation's inside flanging of folding down in inwardly flat folding back, in described chassis, be respectively equipped with inverted U-shaped frid and positive U-shaped pallet, the two ends of inverted U-shaped frid and positive U-shaped pallet are separately fixed on the front and back end wall on chassis, two downward sides of inverted U-shaped frid gap respectively straddle in the adjacent positive U-shaped pallet, flanging on the described dual-side then gap inserts in the adjacent positive U-shaped pallet, is formed with the cross section main body between the flanging on the inverted U-shaped frid between the adjacent inverted U-shaped frid and both sides and the corresponding side and is down trapezoidal air outlet; Be provided with the strip convex tendon that keeps out the wind at place, positive U-shaped pallet centre position, the upper surface of this convex tendon that keeps out the wind exceeds the lower edge of the insertion side of inverted U-shaped frid, between the dual-side of described keep out the wind convex tendon and inverted U-shaped frid, between the side of the dual-side of inverted U-shaped frid and positive U-shaped pallet and be equipped with wind gap between positive U-shaped pallet and the flanging, between the adjacent positive U-shaped pallet, be equipped with air intake passage between positive U-shaped pallet and the corresponding side, described wind gap and air intake passage have formed the labyrinth type cooling air channel.
The quantity of the positive U-shaped pallet of installing in each grate plate is 3～5, and correspondingly the quantity of described inverted U-shaped frid is 2～4.
The beneficial effects of the utility model:
Grate plate of the present utility model chassis is used to be installed in the structural framing of cooling machine, is supporting the wind groove of grate plate, constitutes grate plate comb seam between inverted U-shaped frid and the positive U type supporting plate, and prevents that by the convex tendon that keeps out the wind both sides comb seam is to blowing the generation backflow phenomenon.
Just can form whole labyrinth type cooling structure all be fixedly mounted on the structural framing of cooler when grate plate of the present utility model after, can not produce Lou material phenomenon during the cooler operation, the cooling machine that therefore energy-saving grate plate of the present utility model is installed can save and be used to carry Lou the grog machine for zipper and the airlock of material, reduces the operating cost of device fabrication cost and equipment.Grate plate maintains static simultaneously, and wear extent is smaller, and be more than 10 times of old-fashioned grate plate the service life of grate plate of the present utility model under the normal condition.
The air-out groove of grate plate of the present utility model is seen as trapezoidal shape from end face, can stop material so fully and be stuck in the wind groove, avoids stopping up the appearance that grate plate causes the grate plate burning phenomenon because of material.Grate plate can accomplish never to damage.The air outlet of trapezoidal shape can reduce because material is stuck in the bed of material resistance that increases in the wind groove, reduces the energy consumption of cooling blower greatly.
The utility model can prevent to produce blowing backflow phenomenon owing to grate plate material loading layer resistance is different owing to be provided with the convex tendon that keeps out the wind between comb seam and comb stitch effectively.Stopped the problem that return air leaks material.
Grate plate of the present utility model can adopt the husky monoblock cast of resin, can guarantee the precision of the intensity of grate plate and the seam of combing, and makes air feed system more stable, and is more even.The running rate of cooler can improve 5%～10%, calculates to produce 100 tons of clinker production line daily, can improve the output value 2000～4,000 ten thousand yuan every year.Heat recovery rate can reach 83%, has reduced the system energy consumption of cement kiln.This kind grate plate meets the energy-saving and cost-reducing requirement of country fully.Greatly reduce the annual maintenance cost of changing the grate plate spare part of cement industry, every kiln can be saved 200,000 yuan of the about RMB of spare part expense every year.
