Description

A kind of internal suction dust collector

technical field

The utility model relates to the technical field of dust filtering equipment, in particular to an internal suction type dust collector.

Background technique

The dust filter is mainly used to filter out the dust in the air. Taking cotton spinning production as an example, the dust in the workshop contains stems, leaves, fibers, seed shells, sediment, metal powder, and pesticide residues of cotton crops. They deteriorate the quality of ambient air in the workshop and cause great harm to human health. At the same time, if a large amount of these dust falls on the semi-finished and finished products, it will also affect the quality of the products. Therefore, the textile workshop must take certain technical measures to remove the dust in the air, so that the dust concentration in the workshop air can be maintained within the allowable range, so as to ensure the health of the workers and the normal production. The dust filter mainly separates the dust and particles in the air through the filter material in the cage to achieve the effect of air filtration. After the existing dust filter works for a certain period of time, as the dust accumulates in the filter material, the permeability decreases and the filtering effect becomes worse and worse. It must be shut down to remove the accumulated dust before normal dust filtering can be performed, and continuous filtering operations cannot be performed. .

Therefore it is necessary to provide a dust filter capable of performing continuous filtering operations.
