Circular cooler

Abstract

The invention discloses a circular cooler which comprises a plurality of cooler cooling working units and containing spaces, wherein the cooler cooling working units are sequentially arranged in the circumferential direction; an inner baffle plate, an outer baffle plate, a rear side plate of a front supporting beam, a front side plate of a rear supporting plate, and a trolley grate plate of each cooler cooling working unit form the containing space for containing materials. The lower part of the inner baffle plate is provided with an inner discharging plate, and the lower part of the outer baffle plate is provided with an outer discharging plate. The upper edges of the inner discharging plate and the outer discharging plate are respectively fixedly connected with the plate surfaces of theinner baffle plate and the outer baffle plate, and the lower edges respectively extend into the containing space. Both sides of the inner discharging plate and the outer discharging plate are respectively abutted with the rear side plate of the front supporting beam and the front side plate of the rear supporting beam, and the included angles of four intersecting lines and the horizontal plane are respectively greater than the repose angle of the material. The invention can effectively ensure no material residue in the intersecting position of the profile beam side plate and the baffle plate after discharging, thereby realizing complete discharging, and furthermore avoiding the deformation of the inner baffle plate and the outer baffle plate due to being heated.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to an annular cooler. Background technique [0002] See figure 1 , figure 2 and image 3 ,in, figure 1 It is a schematic diagram of the overall structure of the existing annular cooler, figure 2 for figure 1 A-A partial sectional view of the non-cooling zone of the annular cooler shown, image 3 Yes figure 1 Enlarged view of part B. [0003] The annular cooler 10 is roughly divided into high temperature zone I, medium temperature zone II, low temperature zone III and non-cooling zone IV. The side plates of the support beam 14 constitute an annular cooler for cooling the working unit. During the working process, the trolley 11 and the support beam 14 rotate around the center of the annular cooler 10 in real time and synchronously at a constant speed. That is to say, the ore material to be cooled is sequentially arranged in the accommodation space formed by the inner...

Problems solved by technology

[0005] However, the existing annular cooler is limited by its own structure. After the unloading is completed, there are mineral residues at the junction between the side plate of the support beam and the fence, which cannot meet the requirements of complete unloading.
