3, in order to clear up the bulk material, increased working strength of workers.
For solving the problem of above-mentioned existence, cooling machine grate is had higher requirement:
1, require cooling machine grate intensity to strengthen, the grate plate will have very strong high temperature resistant, shock-resistant, anti abrasive characteristics;
2, the design of grate panel grid will consider that the downslide of bulk materials is smooth and easy, and the appearance of the phenomenon that prevents to get stuck guarantees that the logistics of producing is unimpeded;
3, the selection of the steel plate material that contacts with high-temperature material on the chute should be further considered high temperature resistantly, improve the buildup problem of chute pneumatic door inside bottom and cooler connecting portion release mesh material.
Summary of the invention
The purpose of this utility model provides a kind of grate plate device of cooling machine that satisfies above-mentioned requirements, this device is high temperature resistant, shock-resistant, guarantee that logistics is smooth and easy, and has effectively improved the buildup problem of chute pneumatic door inside bottom and cooler connecting portion release mesh material.
The utility model is achieved through the following technical solutions:
A kind of grate plate device of cooling machine, be formed by connecting by securing member by a plurality of casting grate plates, each casting grate plate comprises a plurality of rectangle grids that are made of vertical gusset and horizontal gusset, whole casting grate plate is and is in tilted layout, and support by grate plate-girder foundry goods, the grate plate end support of lateral arrangement, described grate plate-girder foundry goods end bearing is provided with rubber slab, and rubber slab is positioned at the axle sleeve bottom, leaves the gap between grate plate-girder foundry goods and refractory material.
The upper surface of vertical gusset of described casting grate panel grid is higher than the upper surface of horizontal gusset.
Cooler casing is stretched out in the bottom of described casting grate plate.
The bottom, bottom of described casting grate plate, chute pneumatic door inside bottom and cooler connecting portion are provided with the buildup backward channel of release mesh material, the buildup backward channel is a steel frame, horizontal by placing less than 90 degree, be welded on the cooler housing, being positioned at inclines the scraper-trough conveyer bottom.
Compared with prior art, the beneficial effects of the utility model are:
1, through after improving, very effective by facts have proved to the blocking-up and the eliminating of rotary kiln bulk materials, can guarantee that the logistics of producing is unimpeded, thereby make the cooler steady operation.
2, the cooler housing is the steel construction welded unit, except bulk material outlet portal is promoted to open and close by cylinder, does not have other moving component.So this device structure is simple, installation and easy to maintenance, reliable, can be for a long time, stably work.
3, this device can slow down the bump of bulk material.
4, be applicable to the cooler of all kinds rotary kiln.

The specific embodiment
Be described in detail particular content of the present utility model below in conjunction with accompanying drawing:
See Fig. 1, Fig. 2, grate plate device of cooling machine is made up of grate plate end support () 1, grate plate end support (two) 2, casting grate plate 3, grate plate-girder foundry goods 5, baffle plate () 6, baffle plate (two) 7, bearing 8, axle sleeve 9, rubber slab 10, rubber cushion baffle plate 11, gusset 12, securing member 13 etc.Whole grate plate is made of a plurality of casting grate plates, each casting grate plate comprises a plurality of rectangle grids (seeing Fig. 4, Fig. 5) that are made of vertical gusset 15 and horizontal gusset 14, be stainless securing member 13 connections with material between the casting grate plate, whole grate plate is the inclined-plane and arranges, the grate plate-girder foundry goods 5 that they are made by the heat-resisting alloy steel pipe of lateral arrangement, grate plate end support () 1, grate plate end support (two) 2 support.The mouth of pipe of steel pipe is exposed in the outer atmosphere of housing, and baffle plate 6 is welded on the housing.Since the impact of bulk materials is arranged, a lot of reinforced steels that on surface of shell, have been welded, so that improve the intensity of housing.Hold the volume of bulk materials for increase, prevent to influence the circulation of qualified material, cooler casing is stretched out in the bottom of casting grate plate.
See Fig. 3,5 liang of end bearings 8 of grate plate-girder foundry goods have increased resiliency supported rubber slab 10 and rubber cushion baffle plate 11, leave the gap between grate plate-girder foundry goods 5 and the refractory material 4, the grate plate-girder is in the free floating state, when the bulk material falls, grate plate-girder foundry goods 5 is impacted, by axle sleeve 9 power is passed on the rubber slab 10, rubber slab 10 bounce-backs can be played the effect of buffering, adopt the form of this elastic support, the bulk material can be absorbed to a part of kinetic energy that grate plate bump produces, impulsive force can be alleviated again cooler housing and bearing 8.
See Fig. 4, Fig. 5, casting grate plate is the heat resisting steel foundry goods, has been covered with oblong aperture on it, in the design grid bore is increased, and back taper thickness increases, and makes the grate plate have more high temperature resistant, shock-resistant, anti abrasive characteristics.Vertically the form of gusset 15 has three rows or two to arrange, and the upper surface of vertical gusset 15 (gusset that bulk materials flows to) of casting grate panel grid is higher than the upper surface of horizontal gusset 14, can make the downslide of bulk materials more smooth like this.
See Fig. 6, inclining scraper-trough conveyer 16 and is provided with door 18, the situation that is used to observe the bulk material of observing.Be provided with the buildup backward channel 17 of release mesh material at bottom, bottom, chute pneumatic door inside bottom and the cooler connecting portion of casting grate plate, the buildup backward channel is a steel frame, horizontal by placing less than 90 degree, be welded on the cooler housing, being positioned at inclines scraper-trough conveyer 16 bottoms.Because have the material of a small amount of release mesh also can slip to grate plate bottom along grate plate upper surface, this design has improved the buildup problem of chute pneumatic door inside bottom and cooler connecting portion release mesh material.The material problem is further considered high temperature resistant, and the steel plate material that chute is contacted with high-temperature material changes heat resisting steel into by ordinary steel, can prevent that like this steel plate from damaging because of heating temperature is too high.
