Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to an automatic dust removal pulse dust collector. Background Technology

[0002] Currently, the main type of dust collector used in the domestic feed industry is the baghouse dust collector, which is suitable for collecting fine, dry, non-fibrous dust. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles passes through the filter bags, where the dust is trapped, thus purifying the gas. To ensure the dust collector's dust collection side has self-cleaning and recyclable functions, high-pressure pulsed airflow needs to be injected into the dust collection bags periodically. The expanding filter bags promote the shedding of impurities adhering to their surface.

[0003] Because most existing baghouse pulse jet dust collectors rely solely on pulse jet cleaning, a small amount of dust remains on the filter bag surface after the pulse jet cleaning process, which is difficult to remove. Over time, the gaps between the filter bag fibers become smaller and smaller, affecting dust removal efficiency. This usually requires manual cleaning, which reduces work efficiency and increases labor costs.

[0004] Therefore, it is necessary to design an automatic cleaning pulse dust collector to solve the above problems. Utility Model Content

[0011] The upper cover assembly is symmetrically provided with upper connecting ears on both sides; the filter bag device is provided with lower connecting ears corresponding to the upper connecting ears; the upper connecting ears and the lower connecting ears are connected by a damping connector, and one end of the damping connector is hinged to the upper connecting ear and the other end is hinged to the lower connecting ear; the filter bag device is sealed to the upper cover assembly and the base assembly respectively through corrugated hoses.

[0012] The damping connector includes a screw and spherical bearings at both ends of the screw; the two spherical bearings are respectively hinged to the upper connecting lug and the lower connecting lug; and the upper connecting lug and the lower connecting lug are buffered by installing rubber buffers between them and the spherical bearings.
