Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0016] like Figure 1~3 As shown, the present invention is composed of a base plate 1, a grating plate cover 2, a side plate 4, and wall vents. The base plate 1 is made by cutting a whole steel plate. The air volume is designed flexibly, and the size is easy to control. At the same time, bolt holes are reserved on the bottom plate 1 to connect with the grate beam bolts. The cover of the grate plate is composed of steel pipe and steel plate welded, and the ventilation gr...

Abstract

The invention discloses a maze-sealing clinker cooling grate comprising a bottom plate, grate upper caps and side plates. The bottom plate is provided with projecting wall plate air holes. The grate upper caps are cylinders with one end closed, and reversely covering the wall plate air holes. A gap forms between the closed end of each grate upper cap and the corresponding wall plate air hole, and meanwhile, the lower end of each grate upper cap is provided with a plurality of vent notches, so that the vent notches and the wall plate air holes form maze outlets. The side plates are vertically disposed on two sides of the bottom plate. The grate of the maze sealing structure is formed by welding steel tubes, production cost is reduced greatly, the structure is simple, the maze sealing structure ensures no leakage of the grate, the service life of the grate is prolonged, and maintenance costs are reduced.

Description

[0001] technical field [0002] The invention mainly relates to a new-generation non-leakage cooler grating plate, which is applied to industries such as cement building materials and metallurgy. Background technique [0003] In the whole cement clinker calcination production process, the cooling of cement clinker is a very important process. The main function of the cooler is to improve the quality of cement clinker, improve the grindability of clinker, and increase the emission of waste gas. Heat recovery and utilization improves the thermal efficiency of the kiln. Clinker cooling is an important link in cement production to achieve high quality, high output and low energy consumption. [0004] The clinker cooler is composed of upper and lower shells, supporting devices, grate beds, grate plates, sealing devices, crushing devices, and air supply devices. Among them, the grate plate is one of the most important components. At present, the grate plate of the grate cooler...
