Dust filtering and collecting device

Abstract

The invention discloses a dust filtering and collecting device. The dust filtering and collecting device comprises a hollow device main body. The dust filtering and collecting device is characterized in that a filter is arranged at the upper part in the device main body, wherein the lower part of the filter is in an inverted cone cylinder structure, a plurality of filter screens are arranged in the filter in parallel, and the apertures of the filter screens decrease from the top to the bottom. According to the dust filtering and collecting device, the filter screens are arranged in the filter in parallel, and the apertures of the filter screens decrease from the top to the bottom, so that a step-be-step progression manner is realized, large sundries are firstly filtered, and small sundries are filtered step by step so as to achieve a purpose of completely filtering the dust; as a tee valve is arranged between a vertical pipe and an L-shaped pipe, the dust can be regulated to flow into different collection tanks; gauze nets are arranged at openings of the collection tanks, so that the further filtering of the dust is facilitated, and the cleanliness of the device is maintained; by arranging a ceramic inner layer, the quality of the dust is guaranteed, and the pollution is prevented. The dust filtering and collecting device has the advantages of simple structure, long service life, low cost and the like.

Description

technical field [0001] The invention relates to a filtering device, in particular to a dust filtering and collecting device. Background technique [0002] Dust filter device is a common equipment for filtering dust, which can be widely used in chemical industry, medicine, electronics, textile, coal, petroleum, natural gas, food, glass, machinery, powder metallurgy, magnetic materials and other industries; usually The large debris is separated through the filter screen in the filter, so as to extract relatively pure dust, so that the dust can be transported smoothly; the current dust filter devices are put into use after direct filtration, and there is a lack of a buffer device, that is, As a storage device, the filtered dust cannot be collected well when it is not in use, and staying in the filter for a long time not only causes pollution, but also hinders the completion of other tasks. Contents of the invention [0003] In order to overcome the above problems, the pres...
