Description

The invention relates to devices for the purification of gases by filtration from an aerosol, and can be used in various industrial zones,

The aim of the invention is to provide a tight fit of the filter material to the frames, including the places of its bending, simplification of the package design and the process of its assembly.

FIG. 1 shows an element of the filter package assembly; in fig. 2 - filtering package after laying the canvas and before compression, side view; on (g.Z. filter package in the assembly after compression.

The filter bag consists of rectangular frames 1, to the two sides of the calsda of which are attached strips 2 of elastic material, a zigzag-like filter material 3, a frame 4 with latches 5 and a clamping hook 6.

Equipping the rectangular frames with the sealing elastic material can be carried out, for example, either by gluing it from the top and bottom of two opposite sides of the frame, or by making a cut in the body of the strip of elastic material into which one of the sides of the frame is inserted.

The assembly of the filter bag is carried out in the following sequence.

At the bottom of the frame 4, made of a corner profile, a layer of filter material 3 is laid out of a roll, and on top of it a frame 1, provided with strips 2 of an elastic material. A new layer of filter material is placed on top of the frame, again the frame and so on until the complete package has been laid. Moreover, the frames are stacked identically, sealing material in one direction, after which

A retaining clip 6 is inserted into the frame, compressing the entire package and pressing out the elastic material along a plane perpendicular to the actual compressive force, including at the ends, where

it is tightly clamped to the filter material, provides sealing. The clamped cover is held in position with the snaps 5. After the service life has been exhausted

filter material package can be removed from the filter and refilled new filter material in inventory using the rest of the package design.

The design of the filter bag, as filter parts, allows to achieve high technical qualities, simplicity of device design and with guarantee to prevent the flow of charged gas through the leakiness of the package.
