Description

Bag type dust collector

Technical Field

The utility model belongs to the technical field of dust collecting equipment, concretely relates to bag type dust collector.

Background

The bag-type dust collector is a dry dust filter. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust removal device, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and the dust is blocked when the gas containing fine dust passes through the filter bag, so that the gas is purified. Enterprises often need various procedures such as screening, crushing, mixing and the like on various food raw materials in the process of food processing and production, and fine particle dust such as dust and the like is often generated in the process of processing the food raw materials, so that certain pollution is caused to production workshops and atmospheric environment. The bag type dust collector is one of the dust collectors commonly used in the present dust collecting equipment.

In the conventional bag-type dust collector, dust-containing gas directly impacts a dust-collecting filter bag after entering the dust collector from an air inlet, and the impact frequency is high at the place where the air flow is concentrated, so that the damage to the filter bag is large, and the service life of the bag is shortened. Meanwhile, large granular substances and debris are possibly mixed in the dust-containing gas directly sucked from the external environment, so that the dust-containing gas directly impacts the cloth bag and scratches which are difficult to repair are caused on the filter bag. In the prior art, only a single uniform air speed device or a single primary filtering device is arranged, and a dust removal device capable of achieving uniform air speed and effective primary filtering is not arranged. And the patent technology with the primary filtering device only can be used for processing large particles staying on the filter screen after primary filtering, and the large particles can naturally fall off, so that the technology has no practicability.

Detailed Description

Referring to fig. 1, a bag type dust removing device includes: the device comprises a dust removal device shell 1, an air distribution pipeline 2, a rolling filter screen 3, a filter bag device 4 and a pulse injection device 5; the dust collector is characterized in that an air inlet 6 is formed in the bottom end of the side wall of the dust collector shell 1, an air outlet 7 is formed in the top end of the side wall, an air distribution pipeline 2 is arranged in the dust collector shell 1, one end of the air distribution pipeline 2 is an air inlet 6, the other end of the air distribution pipeline is of a closed structure, a plurality of air outlets 8 are formed in the horizontal direction of the air distribution pipeline 2, the air inlet 6 of the air distribution pipeline 2 is communicated with the air inlet 6 of the dust collector shell, and the pipeline cross-sectional area of the air distribution pipeline 2 is gradually reduced from. Roll filter screen 3 is installed to cloth tuber pipe air outlet 8, brush 9 is installed to cloth tuber pipe air outlet 87 lower extreme, the terminal rolling filter screen 3 that contacts of brush 9.
