Multi-direction adjustable sealing device used for carling air passing chamber of grate cooler

Abstract

The invention relates to a multi-direction adjustable sealing device used for a carling air passing chamber of a grate cooler. A retainer spring I is installed on a short screw in a sleeved mode to exert pressing force on an adjusting plate, wherein the short screw penetrates through the bottom of a peripheral frame. A long screw penetrates through the bottom of the peripheral frame and the adjusting plate, and a retainer spring II is installed on the long screw in a sleeved mode to exert pressing force on a wedge-shaped block. A rectangular sealing piece is located on the adjusting plate and is attached with the lower surface of a movable part. The inclined surface of a wedge-shaped sealing piece is attached to the inclined surface of the wedge-shaped block, and the vertical surface of the wedge-shaped sealing piece is attached to the lateral surface of the movable part. The peripheral frame is located outside the wedge-shaped block, the wedge-shaped sealing piece, the movable part, the rectangular sealing piece and the adjusting plate. The multi-direction adjustable sealing device is used for realizing multi-direction sealing of the movable part, the adjusting screws are used for adjusting the pressing force of the retainer springs so as to enable the sealing piece and the movable part to be tightly attached, and therefore the effect of sealing the movable part is realized.

Description

technical field [0001] The invention relates to a sealing device, in particular to a contact sealing device which can realize independent adjustment in multiple directions and is sealed at the place where the longitudinal beam of the grate cooler penetrates through the air chamber. Background technique [0002] Sealing is a component or measure that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from intruding into the interior of machinery and equipment. Its application involves all aspects of social production. According to whether there is relative movement between the seal and the sealed part, the seal can be divided into two categories: static seal and dynamic seal. Type seal and non-contact seal. The invention relates to a contact seal in the field of dynamic seals. [0003] The contact seal is to achieve the sealing effect by the close fit between the seal and the relative moving...

AI Technical Summary

Problems solved by technology

Due to space constraints, this kind of contact seal generally does not have the function of wear compensation adjustment, and its sealing life depends on the wear resistance of the seal. If the seal is worn out, if it cannot be adjusted in time and the failed seal is replaced, the sealing effect will be greatly reduced.
