Abstract
The utility model relates to a chocked flow grid plate for pushing a grid cooling machine. The chocked glow grid plate comprises a movable grid plate and a static choked flow grid plate which are arranged in parallel, wherein the movable grid plate is connected with a movable beam for pushing the grid cooler; and the static choked flow grid plate is positioned above the movable beam, and is connected with fixed grid plates in front of and behind the movable beam. Due to the adoption of the choked flow grid plate provided by the utility model, the phenomenon of red river of a thermal fine material can be effectively avoided, full and uniform cooling of clinkers and further reduction of a discharging temperature are ensured, the wear of the grid plate is retarded, and the service life of the grid plate is prolonged; and the choked flow grid plate is particularly suitable for reforming an aged grid cooler without replacing main body equipment of the grid cooler, and has a wide application prospect.
Description
Technical field
The utility model relates to a kind of choked flow comb plate that is used to promote grate cooler.
Background technology
In the cement clinker production line, the cooling machine is being born cooling, system's recovery of heat, conveying and broken major function to the manufacture of cement grog as one of the main frame of firing system and key equipment.Promote grate cooler when producing,, on the bed of combing, form the segregation of thickness material, cause the cooling air resistance uneven, present one " red material " band, be commonly called as " Red River " thereby very easily be fed to discharging on the edge owing to the revolution cutting mode of kiln; The comb plate under " Red River " and the backplate easy abrasion on next door, this phenomenon is particularly evident on new type dry kiln.
" Red River " except causing the damage of comb plate and backplate, the grog that also is reflected in out the cooling machine does not obtain cooling, influences grog conveying, storage, grinding and cement performance.In addition; After the comb plate heat damage; The part high temperature chamotte falls in the comb lower air chamber through comb plate breakage, is prone to make comb sealing plate and the parts temperature distortions such as valve air compartment under of bed crossbeam and air compartment down to cause cold wind to leak to machine outside or at the mutual wind of going here and there between each chamber under the bed of combing, grog can not get cooling off.
Summary of the invention
The purpose of the utility model provides a kind of choked flow comb plate that is used to promote grate cooler.
The technical scheme of the utility model is: a kind of choked flow comb plate that is used to promote grate cooler comprises the motion comb plate and the static choked flow comb plate that are set up in parallel; Motion comb plate is connected with the walking beam that promotes grate cooler; Static choked flow comb plate is positioned at the top of walking beam, and is connected with the fixedly comb plate of its front and back.
In order to prevent the plate leakage material of combing, said motion comb plate and said static choked flow comb plate overlap each other.As a kind of optimal way, the elongation of a side of said motion comb plate comb face, a side of said static choked flow comb plate comb face is provided with groove corresponding with it.
As the further announcement to the utility model, said static choked flow comb plate is connected through the fixedly comb plate of angle steel with its front and back.
The beneficial effect of the utility model is: the choked flow comb plate that adopts the utility model to provide; Can effectively eliminate " Red River " phenomenon of hot fines; Guarantee the further reduction of full and uniform cooling of grog and drop temperature, slow down comb plate wearing and tearing, improve comb plate work-ing life; The utility model also is specially adapted to the transformation of old cooling machine, need not to change the main equipment of cooling machine, is with a wide range of applications.
