Filtering equipment of self-cleaning dust collector for spinning

Abstract

The invention discloses filtering equipment of a self-cleaning dust collector for spinning. The equipment comprises an ash collecting bottle, an annular filter screen is fixedly connected into the ashcollecting bottle; the geometric center line of the filter screen is aligned with the center line of the ash collecting bottle; an air chamber is arranged under the ash collecting bottle; the top ofthe ash collecting bottle is connected with a feeding pipe in a sealing manner; a sliding cavity sealed with the feeding pipe is formed in one section of the feeding pipe; a sliding block is connectedinto the sliding cavity in a sealed and sliding mode. A through hole of which the diameter is the same as that of the feeding pipe is formed in the center of the sliding block in a penetrating manner; the side wall of the sliding cavity is in sealed sliding connection with a first connecting pipe; and the tail end of the first connecting pipe is communicated with the air chamber. When meshes of the filter screen are blocked, backflushing is conducted through waste heat of a motor and changing of the gas flowing direction, so that the filter screen is automatically cleaned, on one hand, the situation that the working environment of a textile mill is affected due to reduction of the dust collection efficiency is avoided, and meanwhile electric energy waste and damage caused by idling of themotor are avoided.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a self-cleaning vacuum cleaner filter device for textiles. Background technique [0002] Textile mills will produce a lot of dust during the production process. Dust can enter the human respiratory system and settle on the skin and conjunctiva of the human body, endangering human health; it will also affect production, such as polluting the environment and affecting product quality. , Sometimes the dust can even cause fires and explosions. [0003] In the prior art, dust in textile production is usually absorbed by a vacuum cleaner, but in actual use, a filter needs to be installed at the air outlet to prevent the discharged air from carrying dust. Therefore, in the production of textile factories, a large number of The dust is filtered by the filter, which will block the mesh of the filter. At this time, the suction of the vacuum cleaner decreases. On the one hand, it wastes e...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the dust collectors used in textiles in the prior art are prone to clogging of the meshes of the filter screen after extensive use, resulting in a drop in suction, resulting in idling of the impeller blades, wasting power and causing damage to the motor at the same time. A kind of textile self-cleaning vacuum cleaner filter equipment
