Dust-removal filter bed

Abstract

The invention relates to a dust-removal filter bed, which relates to the field of dedusting devices. The dust-removal filter bed comprises a body, a filter plate, a plurality of pore adjusting piecesand a dust collection bin. Wherein the body is provided with a containing cavity limited by a shell wall, and the shell wall is provided with an inlet and an outlet which are communicated with the containing cavity; the filter plate is provided with a plurality of filter holes, is arranged in the accommodating cavity and divides the accommodating cavity into a first accommodating cavity and a second accommodating cavity, so that fluid input through the inlet sequentially flows through the first accommodating cavity, the filter holes, the second accommodating cavity and the outlet to be output;the plurality of pore adjusting pieces are positioned in the first accommodating cavity and / or the second accommodating cavity, and can be operated to be inserted into the filtering holes to form a pore adjusting state and to be separated from the filtering holes to form a pore non-adjusting state; and the dust collection bin communicates with the bottom of the first containing cavity. Accordingto the dust removal filter bed, the filter aperture can be freely adjusted, the dust-removal filter bed adapts to removal of different particulate matters and is convenient to clean, and meanwhile, the service life of the filter bed is prolonged.

Description

technical field [0001] The present application relates to the field of dust removal devices, in particular to a dust removal filter bed. Background technique [0002] In the fields of dust removal and pollution removal, the filter bed is the main application device of the process, which is the mechanical interception of the filtered particles through the filter material. [0003] Most of the filter beds are molding equipment, and the dust removal and decontamination are carried out through the pores provided. In the actual process of dust removal or decontamination, the filter bed is often clogged or the service life is shortened with the passage of time. Therefore, the existing filter The bed is generally equipped with a regeneration cleaning mechanism, but the regeneration cleaning process of the existing filter bed is relatively complicated, and requires a large amount of energy consumption, and the economic effect is low. [0004] In view of this, the application is her...

[0003] Most of the filter beds are molding equipment, and the dust removal and decontamination are carried out through the pores provided. In the actual process of dust removal or decontamination, the filter bed is often clogged or the service life is shortened with the passage of time. Therefore, the existing filter The bed is generally equipped with a regeneration cleaning mechanism, but the regeneration cleaning process of the existing filter bed is also relatively complicated, and requires a lot of energy consumption, and the economic effect is low
