Spray blowing device of cloth bag dust remover

Abstract

The invention discloses a spray blowing device of a cloth bag dust remover. The spray blowing device comprises an air collecting pipe, wherein a pressure meter is arranged on the air collecting pipe, a compressed air inlet is arranged on the air collecting pipe, the air collecting pipe is communicated with a plurality of spray blowing pipes, the air inlet end parts of the spray blowing pipes are provided with pulse valves for controlling the air inlet of the spray blowing pipes, the spray blowing pipes are uniformly provided with a plurality of spray nozzles in one-to-one correspondence with each cloth bag of the cloth bag dust remover, the inlet ends of the spray nozzles are provided with spray surfaces for integrally spraying out compressed air, the axial lines of the spray nozzles are aligned with the center lines of the cloth bags, and a water discharge valve is arranged on the air collecting pipe. The spray blowing device is automatically controlled, the compressed air is utilized for cleaning dust pasted on the cloth bags, in addition, the compressed air in the spray blowing pipes can be integrally sprayed out through the spraying surfaces, the air force is strong, and the dust removal effect is obvious.

Description

technical field [0001] The invention relates to the field of bag dust collectors, in particular to a blowing device for bag dust collectors. Background technique [0002] The working principle of the bag-type dust collector is that the dust-containing air enters each dust-removing chamber from the air inlet. Each dust-removing chamber is equipped with a cloth bag for filtering dust. The dust is filtered by the cloth bag and sticks to the outer periphery of the cloth bag. The outer peripheral dust is cleaned, but the design of the blowing device of the current bag filter is unreasonable, the blowing effect is not ideal, the compressed air force of the blowing is not enough, and the compressed air flow is scattered, resulting in insufficient impact on the bag. Incomplete dust removal will have a negative impact on the follow-up bag dust removal effect. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a blowing dev...
