Metal sealing device of trolley of annular cooler

Abstract

The invention provides a metal sealing device of a trolley of an annular cooler. The metal sealing device is mounted between a rotary frame beam and the trolley and comprises a fixing piece, a metal plate, elastic stretchable devices, wherein the upper end of the fixing piece is fixed on a bottom surface of the rotary frame beam, the upper portion of the metal plate and the lower portion of the fixing piece are overlapped and can vertically move relative to the fixing piece, two lateral transverse ends of the metal plate extends out relative to the fixing piece, the elastic stretchable devices are arranged among the two lateral transverse ends of the metal plates and the bottom surface of the rotary frame beam, each elastic stretchable device comprises an elastic component which enables the lower portion of the metal plate to always press the surface of the trolley tightly.

Description

technical field [0001] The invention relates to a sealing device, in particular to an elastic metal sealing device for a trolley of a water-sealed annular cooling machine for plane sealing. Background technique [0002] At present, most domestic large-scale annular coolers use water-sealed annular coolers, which hinge a plurality of trolleys through a roughly annular rotary frame beam. One side / end of each trolley is hinged with the slewing frame beam. Each trolley has a double-layer structure. The upper layer is a grate plate for sintering ore, and the lower layer is a cooling air chamber and also has the function of bulk material collection. The working principle of the ring cooler is: when the trolley of the ring cooler rotates clockwise along the fixed center point on the horizontal plane, the high-temperature sintered ore is distributed to the upper layer of the trolley, and the cold air from the blower enters the lower layer of the trolley through the air duct to cool ...

AI Technical Summary

Problems solved by technology

[0004] This sealing method exposes many problems during use: 1. The service life of the seal is short. Under the baking of high-temperature sintered ore, a large number of silicone rubber sealing plates will be burned in an average of 2 to 3 months, and the price of the seal is high. Large consumption; 2. The fixed rubber plate belongs to the static sealing method. After the seals or the structural parts of the trolley (such as wheels, tracks, hinge seat bearings, etc.) are worn, the gap between the seals increases and cannot be automatically compensated, resulting in serious material leakage , air leakage; 3. It is very difficult to replace the seal after damage, especially the space on both sides of the fixed hinge seat of the trolley is narrow, and it takes a long time to replace the seal of a trolley during maintenance, which cannot guarantee the actual production needs

[0005] Aiming at the sealing problem existing in the above trolley during use, combined with the specific conditions of sintering equipment operation, the present invention proposes a new type of sealing device
