Rigid member for installing filtering element on pore plate and filtering structure applying rigid member

Abstract

The invention discloses a rigid member for installing a filtering element on a pore plate and a filtering structure applying the rigid member. The technical purpose is to solve the problem mentioned in the background art that pretightening force between a convex shoulder and the pore plate is concentrated. The filtering element which the rigid member is applicable to comprises a filtering part and a connecting part located at the end of the filtering part, the connecting part forms the convex shoulder relative to the filtering part, and the end surface, away from the filtering part, of the convex shoulder is provided with a clean gas delivery outlet which is communicated with the cavity of the filtering part; the rigid member comprises a side body part, a bending part and a stressing part, wherein the side body part is used for being arranged on the side surface of the convex shoulder and extending along the broadside of the convex shoulder, the bending part is formed by bending edges of the side body part and is used for being turned upside down on the end surface, away from the filtering part, of the convex shoulder or the end surface, close to the filtering part, of the convex shoulder, so that the space between the convex shoulder and the pore plate is uniformly and tightly pressed within the length range of the broadside of the convex shoulder and sealing contact is achieved, and the stressing part is used for achieving pretightening connection between the rigid member and the pore plate through a pretightening part.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular, to a rigid member for installing a filter element on an orifice plate and a filter structure using the same. Background technique [0002] Whether in industry or civil use, in order to obtain pure gas, it is the most basic method to remove dust in the gas through filtration. Generally speaking, some of the dust contained in the gas is settleable dust, and some are suspended particles. Suspended particulate matter in gas refers to particles suspended in gas that are not easy to settle. The particle size of suspended particulate matter in the air is generally ≤100 microns; among them, suspended particulate matter with a particle size of ≤10 microns is also called PM10, and those with a particle size of ≤2.5 microns are also called PM2.5. [0003] In order to facilitate the settlement of dust, the existing filter and dust removal equipment generally fixes the filter element by po...
