Description

Technical Field

[0001] The utility model relates to the technical field of grate cooler unloading, in particular to a grate cooler unloading device with flow splitting and self-adjusting wind locking functions. Background Art

[0002] The grate cooler is an important equipment in the dry process of cement production. It is usually composed of an upper shell 1, a grate bed 2, a lower shell 3 and a fan cooling system 6. A discharge device 4 is arranged at the tail of the grate bed 3, and a zipper machine 5 is arranged below the discharge device 4. Figure 1 As shown, Figure 1 The arrows in the figure represent the material flow direction.

[0003] like Figure 1 As shown, the material cooled by the grate cooler falls from the grate bed 2 of the grate cooler through the discharge device 4 at the tail of the grate cooler into the zipper machine 5 located below the grate cooler. There is generally a height difference of 2-3m between the grate bed 2 and the zipper machine 5. Compared with the material in the middle of the grate bed 2, the material on both sides of the grate bed 2 forms dead material on the material receiving step because of the material receiving step of the discharge device 4 when the grate cooler starts to run, and then forms a material discharge slope, which increases the distance from the grate bed to the zipper machine for subsequent materials; while the material in the middle of the grate bed 2 does not have the material receiving step of the ash hopper (discharge device 4), and will not form dead material, causing the material to fall directly from the grate bed 2 into the zipper machine 5, as shown in FIG. Figure 2 shown.

[0004] The existing problem is that the intermediate material falls directly from the grate bed into the zipper machine. On the one hand, the material causes impact and wear on the zipper machine, generating noise; on the other hand, some powdery materials cause dust in the process of falling, and dust collection holes need to be added, resulting in air leakage in the system.

[0005] At present, the design of the cross-sectional area of ​​the discharge device is determined according to the capacity of the grate cooler and historical experience. The existing problems are: if the outlet cross-sectional area is too small, the material will not be discharged smoothly, resulting in blockage, which will affect the output of the entire production system; if the outlet cross-sectional area is too large, the material will further cause dust, and the dust collection holes will be opened on the zipper machine, which will lead to air leakage in the system; increase the load of the fan system; increase the power consumption of the grate cooler system, and finally affect the overall performance indicators of the grate cooler.
