Abstract

The invention relates to an annular refrigerator trolley grating plate which is installed on a trolley body. The grating plate comprises a grating plate basal body and a cover plate, wherein the cover plate is integrally molded with the grating plate basal body and arranged at the front end of the grating plate relative to the moving direction of an annular refrigerator, and a first preset distance exists between the cover plate and the previous grating plate in a vertical direction;; the first preset distance is smaller than the grain diameter of materials delivered by the grating plates; a second preset distance exists between the grating plate basal body and the previous grating plate in the horizontal direction; the second preset distance is smaller than the width of the cover plate and larger than the mutual interference critical distance when the grating plates unload materials. The invention provides the annular refrigerator trolley grating plate for solving the problem of material leakage among the grating plates.

Description

technical field [0001] The invention relates to an annular cooler, in particular to a trolley grate plate of an annular cooler. Background technique [0002] In the prior art, there are mainly three methods for preparing pellets, namely: the method of producing pellets in a shaft furnace, the method of preparing pellets by a belt roaster, and the method of preparing pellets by a chain grate-rotary kiln method. Compared with the other two methods, the grate machine-rotary kiln method has many advantages such as good product quality, large single-machine production capacity, and suitable for large-scale production, so it is widely used. [0003] When the rotary kiln is in operation, the materials in the rotary kiln are continuously turned and roasted to meet the process requirements of the output product. The temperature of the oxidized pellets coming out of the rotary kiln can reach about 1200 degrees Celsius, which needs to be cooled by a ring cooler. The pellet temperature...
