AI Technical Summary

⚠Technical Problem

During food processing, powdery materials are prone to splashing and causing powder contamination. Traditional coarse filters are easily clogged, making cleaning cumbersome and affecting the efficiency of the dust collection hood, thus increasing operating costs.

⚗Method used

A food processing dust collection hood device was designed, comprising a hood body, a dust collection cylinder, a fan, a coarse filter, and a back-blowing structure. By blocking the back-blowing holes with baffles, high-pressure gas is used to back-blow and clean the clogged filter, achieving convenient and efficient cleaning.

🎯Benefits of technology

It effectively prevents the diffusion of powdery materials, extends filter life, reduces cleaning labor intensity and operating costs, and improves dust collection efficiency.

Abstract

The utility model discloses a food processing dust absorption cover device belongs to dust absorption cover technical field, including cover body and dust absorption cylinder, the inside fan installation of dust absorption cylinder upper end, the inside coarse -efficiency filter installation of lower extreme, and the dust absorption cylinder one side is provided with blowback hole, and is connected blowback cylinder, the dust absorption cylinder inner wall is rotationally connected with the baffle, and the dust absorption cylinder inner wall all around is equipped with the fender. In the process of food processing adds powdery material, baffle and corresponding dust absorption cylinder inner wall adhere to adsorption, and the blowback hole is blocked, and the fan rotates produces negative pressure, and the powdery material that drifts is adsorbed through coarse -efficiency filter, when coarse -efficiency filter is blocked, the baffle is rotated upward, makes baffle and fender adhere to adsorption, controls high pressure gas source device and sprays high pressure gas to blowback cylinder, and the coarse -efficiency filter is cleaned to blowback, thereby can realize the convenient, efficient cleaning of coarse -efficiency filter, avoids the frequent disassembly to coarse -efficiency filter, effectively reduces the labor intensity, prolongs the life, and reduces the operating cost.
