Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chain grate machines, in particular to a floating sealing device for a wind box partition wall of a chain grate machine. Background Art
[0002] At present, a sealing groove is usually opened on the top of the wind box partition wall, and stuffing is placed in the sealing groove to achieve the purpose of sealing between the wind boxes of the chain grate machine. However, when running under high temperature for a long time, the chain is prone to deformation, elongation, and falling, which will cause the chain to scrape the sealing groove, thereby interfering with the normal operation of the chain. At this time, in order to ensure normal production, the height of the sealing groove can only be lowered. However, as the gap between the sealing groove and the chain increases, the sealing becomes worse, and the cross-wind between the wind boxes is serious, which restricts the increase in production.

[0006] Preferably, the quick-release mechanism includes a pair of fixed clamps fixed to the top surface of the horizontal section, a movable clamp is arranged between the two fixed clamps, and a locking bolt is threadedly connected to the fixed clamp on either side, and the locking bolt drives the movable clamp to cooperate with the fixed clamp on the other side to lock the strip seal.
[0007] Preferably, the strip seal is made of graphite.
[0008] Preferably, the elastic member is a high temperature resistant spring.
[0009] Preferably, at least one of the upper and lower sides of the high temperature resistant spring is provided with a spring guide pin.
[0010] Compared with the prior art, the utility model has the following advantages:
[0011] 1. When an elongated chain passes through, the chain can compress the elastic part through the strip seal, reduce the resistance to the chain, and ensure the normal operation of the chain grate. The sealing surface composed of the strip seal and the sealing plate can continuously ensure that each bellows has good sealing performance, thereby increasing production.
[0012] 2. The strip seal is installed on the top surface of the horizontal section through a quick-release mechanism, which is convenient for replacement and maintenance. The strip seal is made of graphite with good lubricity, which further reduces the resistance and wear on the chain. BRIEF DESCRIPTION OF THE DRAWINGS
