Description

TECHNICAL FIELD

[0001] The utility model relates to dust remover technical field especially a dust cleaning device for bag type dust collector. BACKGROUND

[0002] The bag type dust collector is a kind of dry filter dust device. It is suitable for capturing small, dry, non-fibrous dust, mainly by upper box, middle box, lower box (ash bucket), dust cleaning mechanism (filter bag) and ash removal mechanism and other parts. Since filter bag is usually made of woven filter cloth or non-woven felt, when dust-containing gas enters the bag type dust collector, the dust with large particles and specific gravity settles down due to gravity and falls into the ash bucket. The gas containing fine dust is filtered through the filter bag, and the dust is blocked, so that the gas is purified. Therefore, the filter bag of the existing bag type dust collector will accumulate a layer of dust on the inner wall after long-term use. As the dust accumulates on the inner wall of the filter bag, the dust removal resistance of the filter bag increases, which reduces the efficiency of the dust collector. The dust cleaning mechanism usually uses vibration to make the dust on the inner wall of the filter bag fall off, which has low efficiency. Moreover, high-frequency vibration will affect the installation stability of the filter bag.

[0003] In order to solve the above technical problems, Chinese patent document CN202222336816.4 discloses a dust cleaning mechanism for bag type dust collector, which includes a dust removal box body.

The side surface of the dust removal box body is provided with a dust inlet. The bottom end of the dust removal box body is provided with an ash removal element. The inner wall of the dust removal box body is fixedly installed with a fixed rod. The side surface of the dust removal cloth bag is provided with a support rod. The bottom end of the support rod is fixedly connected with the lower surface of the fixed rod. The bottom end of the support rod is fixedly installed with a servo motor. The bottom end of the servo motor is provided with a knocking assembly. By setting the knocking assembly, the dust attached in the dust removal cloth bag is vibrated down, so as to keep the dust removal cloth bag unobstructed.
