Description

Technical Field

[0001] The invention belongs to the technical field of sintering pellet production equipment in the metallurgical industry, and in particular relates to a double-flexible sealing device for a chain grate bellows. Background Art

[0002] During pellet production, the operating temperature of the chain grate is very high, and the terminal temperature reaches about 1000 degrees. The chain of the chain grate will inevitably deform and stretch as a whole under high temperature. The phenomenon of chain buckling between each set of rollers is very obvious, and the seal between the bellows of the chain grate is usually composed of a sealing groove filled with balls and materials to achieve the purpose of sealing. Once the metal edge of the sealing groove is high, when the chain is stretched, it will directly scrape the chain and interfere with the normal operation of the chain. In order to ensure normal production, the edge of the sealing groove can only be lowered as much as possible, and the chain cannot be scraped, which results in a large gap between the sealing device and the chain, and the sealing effect is very poor. There is serious cross-wind between the bellows, which restricts the increase in production and increases environmental pressure. Summary of the Invention

[0006] The adjustment and limiting device includes a redirecting wheel arranged on the sealing base, an adjustment mechanism arranged on the frame, one end of which is connected to the multiple groups of flexible sealing blocks, the other end of which is connected to the adjustment mechanism and a flexible zipper that bypasses the redirecting wheel,

[0007] The multiple groups of flexible sealing blocks are connected to the sealing base through fixed limiting devices.

[0008] Each flexible sealing assembly includes a flexible sealing plate, upper and lower limit devices arranged on the flexible sealing plate, and a flexible sealing component arranged in a limit groove formed by the upper and lower limit devices and the flexible sealing plate. The flexible sealing component is fixed in the limit groove by a longitudinal limit device.

[0009] The flexible sealing assembly is composed of several flexible sealing brushes arranged side by side. Each flexible sealing brush comprises a base and a flexible brush arranged on the base.

[0010] The elastic supporting mechanism and the elastic sealing mechanism are arranged in one or more groups.

[0011] The flexible zipper is a chain or a steel rope.
