Circulation cooler

Abstract

The invention discloses a circulation cooler which comprises a plurality of trolleys. The trolleys are arranged in a circumferential direction in sequence and the front end of each trolley is articulated with a hinging base fixed on a support beam base plate through a hinging structure. The hinging structure particularly comprises a first hinging ear plate, two second hinging ear plates and a hinging shaft, wherein the first hinging ear plate is fixed at the front end part of each trolley, the two hinging ear plates are fixed at the bottom of the hinging base and respectively arranged at two sides of the first hinging ear plate, the hinging shaft is inserted in hinging holes of the first hinging ear plate and the two second hinging ear plates so that the trolleys can turn around the hinging shaft. Preferentially, in the radial cross section of the circulation cooler, the height of the upper surface of the first hinging ear plate is decreased progressively from the middle part to two sides. The invention has reasonably designed and reliable structure, accords with the design idea of complete unloading of the trolleys of the circulating cooler, fundamentally resolves the problem that the service life of a sealing component is influenced when material accumulates at the position of the first hinging ear plate, thereby further improving the overall working stability.

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. Wherein, the front end of the main body of the trolley 11 is hoisted on the front support beam 14 through the hinged seat 18 , and the rear end of the main body of the trolley 11 is supported on the ring guide rail 19 through the supporting wheels 112 .

Problems solved by technology

In this way, during the resetting process of the trolley 11, the mineral material accumulated between the two hinged lugs 113 and on the upper surface will be offset against the seal of the static sealing device of the adjacent trolley unit, thereby causing the seal to be damaged. In severe cases, it will cause plastic deformation of the lower plate of the trolley and affect the sealing effect of the trolley

[0006] In addition, there is also such a problem in the existing structure that there will be small pieces of mineral material accumulated on the upper surface of each hinge lug 113. Obviously, the residue of small pieces of mineral material will also affect the service life of the sealing member, seriously , it will also cause plastic deformation of the lower plate of the trolley
