Problems solved by technology
[0005] (1) Air leakage problem: The effective air flow path of the annular cooler should be through the grate bar gap of the trolley to the material layer, then through the sealing cover to the fan, until it is discharged into the atmosphere through the chimney
Because the ring friction plate is easy to deform, and after long-term friction at high temperature, the rubber sealing plate is easily torn or squeezed off by the trolley railing, causing harmful cold air to enter the ring cooler, resulting in air leakage
[0006] (2) Uneven distribution of the trolley: Since the bottom surface of the trolley of the annular cooler is fan-shaped, and the distribution funnel and chute are not easy to make the charging line vertical to the trolley fence, and the feeding is not balanced, the material flow is unstable, Therefore, the distribution of materials on the trolley is uneven, resulting in a prominent short-circuit of the draft and a decrease in cooling efficiency
[0007] (3) Reasons for deviation and adjustment methods
[0011] 3.2. The inner and outer horizontal circular tracks are not concentric
[0013] 3.3, side rail installation error

The invention discloses a disc type independent air supply ring cooler. The disc type independent air supply ring cooler comprises a bottom machine frame (101); an inner rotary frame (102) and an outer rotary frame (103) are arranged on the bottom machine frame (101); the bottom surface of the inner rotary frame (102) is located on an inner carrier roller ring (106) through an inner guide rail (104); the bottom surface of the outer rotary frame (103) is located on an outer carrier roller ring (107) through an outer guide rail (105); the inner carrier roller ring (106) and the outer carrier roller ring (107) are arranged on the bottom machine frame (101); and a plurality of connecting beams (108) are uniformly distributed between the inner rotary frame (102) and the outer rotary frame (103). The disc type independent air supply ring cooler has the advantages of being reasonable in design and very good in practical application and popularization value.
Description
Technical field [0001] The invention relates to the technical field of ironmaking and sintering equipment, in particular to a new type of disk-type independent air-supplying ring cooler. Background technique [0002] In steel production enterprises, sintering is one of the ironmaking processes. The process is to mix powdered ore powder and coke powder through a sintering machine to make them into particles of a certain size to facilitate smelting. The sintered ore passing through the sintering machine needs to be cooled, and the cooling is mainly achieved through the air cooler below. At present, the cooling machines used by iron and steel enterprises have two forms: belt coolers and ring coolers. Ring cooler is the abbreviation of ring cooler, and its function is to effectively cool the sintering hot ore discharged from the sintering machine. Compared with the belt cooler, the ring cooler has the advantages of less floor space, less investment, and higher equipment utilization...
