Hold-down device for filter plate of plate-type deduster

Abstract

The invention discloses a hold-down device for a filter plate of a plate-type deduster. The hold-down device includes an installing channel steel (1) welded on the bottom of a tube nest (8); the installing channel steel is connected with a guide rail (2) and a guiding channel steel (5) through bolts; the guide rail is connected with a supporting plate (3) through a pin roll; the supporting plate is connected with the guiding channel steel; the front end of the guide rail is weldedly provided with a fixing block (6); the front end of the guiding channel steel is weldedly provided with a thread block (7); the guide rail and the fixing block are connected with the guiding channel steel and the thread block through a locking screw (4); the upper surface of the guiding channel steel is provided with a tray (9) through the supporting plate; the bottom of the tube nest is contacted with the tray; the lower side of the tray is connected to the filter plate (10). The filter plate is tightly pressed on the tube nest, a dust-containing chamber is separated from a clean air chamber, the hold-down amplitude adjustability is realized, the service life of a sealing rubber strip is prolonged, the self-locking ability of screw threads allows the device to have no need of additional increase of fixing components, and a large amount of dust-containing gas is avoided from passing through a gap between the filter plate and the tube nest to enter the clean air chamber.

Description

technical field [0001] The invention relates to a plate type dust collector, in particular to a filter plate pressing device of the plate type dust collector. Background technique [0002] In recent years, with the development of the dust removal industry, the plate dust collector, as a new type of dust removal device with a small footprint and a large filtration area, has gradually been accepted and promoted by everyone. However, because the filter plate of the existing plate type dust collector does not have a skeleton support like a cloth bag, the filter plate without a skeleton support cannot be installed horizontally, but can only be installed vertically. Due to the limitation of this structure, the plate type dust collector cannot be expanded in the vertical direction, but can only be expanded in the horizontal direction. The intercommunication between them makes the filter plate lose its dust removal function, and a large amount of dusty gas will enter the clean air ...

Problems solved by technology

However, because the filter plate of the existing plate type dust collector does not have a skeleton support like a cloth bag, the filter plate without a skeleton support cannot be installed horizontally, but can only be installed vertically

Due to the limitation of this structure, the plate type dust collector cannot be expanded in the vertical direction, but can only be expanded in the horizontal direction. The intercommunication between the filter plates will cause the filter plate to lose its dust removal function, and a large amount of dusty gas will enter the clean air chamber through the gap between the filter plate and the flower plate, so that the gas emission cannot meet the standard
