Sealing structure for runner air chamber

Abstract

The invention discloses a sealing structure for a runner air chamber. The sealing structure comprises an elastic sealing ring, a fixing ring, a fixing piece and a pressure plate, wherein the outer side wall of the elastic sealing ring is connected with the runner air chamber; the fixing ring is coaxially fixed to the outer end face of the elastic sealing ring, the end face, away from the elastic sealing ring, of the fixing ring is provided with an extending outer cylinder in the axis direction of the fixing ring, and the extending outer cylinder and the runner air chamber are fixedly connected; a pressing space is formed between the inner side surface of the fixing ring and the inner side surface of the elastic sealing ring; and the pressure plate is detachably installed on the fixing ring through the fixing piece and used for extruding the elastic sealing ring located in the pressing space. According to the sealing structure for the runner air chamber, the elastic sealing ring can be conveniently fixed to the inner wall of the runner air chamber; and extrusion of the elastic sealing ring extruded by the pressure plate is changed by changing the tightness degree of the fixing piece, then the deformation condition of the elastic sealing ring is changed, the sealing degree of the elastic sealing ring is changed, and adjustment can be conducted according to the use time of the elastic sealing ring.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sealing structure for a runner air chamber. Background technique [0002] The zeolite runner is a kind of concentrated volatile organic compounds (VOCs), which is then sent to the incineration equipment for purification treatment, which includes an adsorption zone, a desorption zone and a cooling zone, and the concentration of volatile organic compounds (VOCs) in the adsorption zone ) for adsorption to achieve the purpose of concentrating VOCs. In the desorption zone, the concentrated VOCs are desorbed by hot air and sent to the incineration device for purification treatment; then the zeolite wheel is cooled through the cooling zone to continue the adsorption. for adsorption and desorption purposes. There is a partition in the runner to divide the runner into an adsorption zone, a desorption zone and a cooling zone, and a sealing gasket is often set ...

AI Technical Summary

Problems solved by technology

There is a partition in the runner to divide the runner into an adsorption zone, a desorption zone and a cooling zone, and a sealing gasket is often set at the connection between the partition and the inner wall of the runner to achieve a sealing effect and avoid cross-gas in each zone, but now Some generally use a rubber pad, which is not easy to reuse, and the deformation of the rubber pad cannot be adjusted to achieve different sealing effects
