A sealing structure for the air chamber of the runner

Abstract

The invention discloses a sealing structure for a runner air chamber, comprising an elastic sealing ring, a fixed ring, a fixing piece and a pressure plate, wherein: the outer wall of the elastic sealing ring is connected with the runner air chamber; the fixing ring is coaxially fixed On the outer end surface of the elastic sealing ring, and the end surface of the fixed ring away from the elastic sealing ring has an extended outer cylinder along its axis direction, and the extended outer cylinder is fixedly connected with the runner air chamber; the inner surface of the fixed ring is connected with the inner surface of the elastic sealing ring A pressing space is formed between the sides; the pressure plate is detachably mounted on the fixing ring through the fixing piece, and the pressure plate is used for pressing the elastic sealing ring located in the pressing space. In the present invention, the proposed sealing structure for the runner air chamber is convenient for fixing the elastic sealing ring on the inner wall of the runner air chamber; by changing the degree of tightness of the fixing piece, changing the extrusion of the pressure plate to squeeze the elastic seal ring, Further changing the deformation of the elastic sealing ring and thus changing the sealing degree of the elastic sealing ring can be adjusted according to the service 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
