Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal equipment, in particular to a spray angle adjustment device based on a pulse dust collector. Background Art

[0002] When the particles accumulate to a certain extent, the pulse dust collector will affect its working efficiency, and cleaning is required. When cleaning, a pulse signal is first sent through the pulse control device, which triggers the opening of the cleaning solenoid valve. When the solenoid valve opens, high-pressure gas will quickly spray into the dust filter bag. The gas sprayed into the dust filter bag will form a strong airflow, which quickly sweeps the inside of the filter bag to remove the particles on the filter bag.

[0003] Since the nozzle of the injection pipe and the dust filter bag are located on the adjacent two sides of the dust box and are distributed at right angles, the airflow needs to be sprayed horizontally from the injection pipe to the dust box, and then turned to the dust filter bag at the bottom of the dust box to achieve the purpose of cleaning. The airflow cannot directly act on the inner surface of the dust filter bag, resulting in a poor cleaning effect. Utility Model Content
