Description
Technical field
The utility model belongs to cement manufacturing technology field, specifically is to directly apply to the grog cooling of chamotte cooler and a kind of new and effective grate plate of carrying.
Background technology
Chamotte cooler is as one of crucial main process equipment of cement factory firing system, bearing main effect such as cooling, conveying, fragmentation and system's recuperation of heat to the manufacture of cement grog, along with the continuous development of technology of producing cement and improving constantly of factory management level, its importance status is more and more paid attention to by people, adopts energy-efficient, reliable chamotte cooler to guaranteeing that system's production capacity is strong, energy consumption is low, running rate is high and system's stable operation is significant in modern dry production firing system.
Present widely used chamotte cooler is the driving grate cooler, and the specification size of a cooling machine is decided by desired output.Therefore, the length of cooling machine must become more and more longer with production-scale increase, needs the big cooling machine of production scale is divided into several comb bed sections for this reason, disposes independently transmission device respectively.Its purpose is to make the part of comb bed and transmission to be unlikely to too huge, is convenient to make transportation and reduces cost.In addition, can make each section comb bed, satisfy the requirement that obtains different thicknesses of feed layer on the bed of combing with different comb speed operations.Comb bed for high temperature section substantially all is the high-drag grate plate that adopts inflation beam air feed, comb bed for low-temperature zone, owing to obtain bigger reduction after the comb bed cooling of clinker temperature through the front, and the grog layer attenuation below the parts of fine grog drains to the bed of combing above the grate plate of back, this has just caused cooling air to reduce greatly by the resistance of grog layer, thus mostly the cooling machine to make producer all be the cellular type grate plate that adopts by the direct air feed of air compartment at this.Adopt the cost that has reduced grate plate really of cellular type grate plate and the power of blower fan, but the leakage material amount of cellular type grate plate increases greatly, increased the bed load of surface conveyer down of combing, the transfer efficiency of the bed of combing is relatively low, has increased the power of main driving motor.If equally adopt the high-drag grate plate of inflating the beam air feed with high temperature section, must waste the power of blower fan, increase the power consumption of equipment.
Summary of the invention
The technical problem that the utility model solves is at chamotte cooler low-temperature zone grate plate problem of non-ideal use.Concrete technical scheme is as follows:
A kind of new and effective grate plate, described grate plate is connected and composed by a plurality of independent grate plates; Described independent grate plate comprises grate plate main body, air inlet, grate plate face and air outlet, and air inlet is located at grate plate main body below, and the grate plate face is located at grate plate main body top, is provided with air compartment in the grate plate main body.Described air outlet is located on the grate plate face; The grate plate face comprises a plurality of " ∽ " shape plate; The bossing of " ∽ " shape plate is stacked in adjacent ∽ " negative area of shape plate, constitute narrow slit, described narrow slit is described air outlet.
Described air inlet has two, is provided with the grate plate support between two air inlets.Like this can be less demanding to the blast of air intake, the setting of grate plate support also can be played the effect that is connected and fixed grate plate.
Described grate plate face tilt is in horizontal direction.
Described independent grate plate and horizontal direction tilt to place; The part bottom of grate plate main body is pressed on the part grate plate face of adjacent independent grate plate.
The utility model adopts the direct air feed of air compartment, reduces the power of blower fan, and the grate plate face is made up of some " ∽ " shape plate, forms some narrow slits simultaneously therebetween, and the cooling air enters into covering grog layer in the above by these narrow slits." ∽ " structure can play the effect of water conservancy diversion to the cold wind that passes through, and cold wind is blown in the grog layer obliquely, the conveying of grog is played the effect of boosting; Simultaneously, this structure forms labyrinth one by one each other again, has reduced the leakage of thin grog effectively, and because a part of grog of concave part branch " storage " has reduced the wearing and tearing between grate plate and the grog, has prolonged the service life of grate plate.This kind grate plate is that employing is high temperature resistant, anti-abrasive material is made, and is easy to machined after the casting, and is quick and easy for installation.
The utility model has successfully applied on many new type nonaqueous cement clinker production line, and the novel grate plate of this kind of evidence is easy to manufacture, and machined and installation are all very convenient, good cooling results, and it is few to leak material, and the life-span is long.
Description of drawings
Fig. 1 is among the embodiment, the side cross-sectional schematic of independent grate plate.
Fig. 2 is among the embodiment, independent grate plate schematic top plan view.
Fig. 3 is among the embodiment, this grate plate use principle schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
A kind of new high-efficiency grate plate, described grate plate is connected and composed by a plurality of independent grate plates 1; Described independent grate plate 1 comprises grate plate main body 2, air inlet 3, grate plate face 4 and air outlet 5, and air inlet 3 is located at grate plate main body 2 belows, and grate plate face 4 is located at grate plate main body 2 tops, is provided with air compartment in the grate plate main body 2.Described air outlet 5 is located on the grate plate face 4; Grate plate face 4 comprises a plurality of " ∽ " shape plate 6; The bossing of " ∽ " shape plate 6 is stacked in adjacent ∽ " negative area of shape plate, constitute narrow slit, described narrow slit is described air outlet 5.
Described air inlet 3 has two, is provided with grate plate support 7 between two air inlets.
Described grate plate face 4 favours horizontal direction.Described independent grate plate 1 tilts to place with horizontal direction; The part bottom of grate plate main body 2 is pressed on the part grate plate face 4 of adjacent independent grate plate 1.
As shown in Figure 3, cold air is blown in the air compartment by blower fan, blows to obliquely in the grog layer after having " ∽ " type structure water conservancy diversion through this grate plate is described again.Require the gap design of adjacent two " ∽ " templates 6 to be got according to the resistance of actual grog layer enough little, thereby reduce a thin clinker quantity that drains to from the grate plate slit below combing bed; Because this grate plate is processed easily, the gap " M " between the independent grate plate of adjacent two rows also can be controlled in the very little scope leakage material amount when reducing the grate plate motion.Grate plate only just can be fixed on the comb board roof beam by three bolts, and the position of construction bolt is provided with boss or is tilted to down, and with double nut locking, can effectively prevent bolt looseness or comes off.The groove that " ∽ " template on the grate plate forms can reduce effectively grate plate in motion process with the contacting of grog, thereby reduce the wearing and tearing of grate plate, increase the service life.
