Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, and particularly relates to a pulse bag filter. Background Art

[0002] A dust collector is a device that separates dust from flue gas. Among them, the most commonly used one in industry is a bag filter. The bag filter filters the dust-containing gas through the filtering action of fiber fabrics to purify the gas. At the same time, because the filter bag filters the gas for a long time, a layer of dust will adhere to the surface of the filter bag. At this time, it is necessary to clean the dust accumulated on the surface of the filter bag. However, the existing technology is not perfect enough in optimizing the disassembly of the bag filter.

[0003] The patent application number "CN202221031471.5" discloses "a pulse bag filter, including: a dust collector body, a clean gas chamber and a dust removal chamber are arranged on the dust collector body from top to bottom, the clean gas chamber and the dust removal chamber are separated by a partition plate, a plurality of filter bags are arranged on the partition plate, a pulse jet assembly is arranged on the side wall of the dust collector body, and a dust hopper is arranged on the side wall of the dust removal chamber; and a dust settling assembly is arranged on the side wall of the dust collector body, the dust settling assembly includes a blower, a first ventilation pipe, a plurality of second ventilation pipes and a plurality of ventilation nozzles, the blower is communicated with the plurality of second ventilation pipes through the first ventilation pipe, the plurality of second ventilation pipes are uniformly arranged inside the dust removal chamber along the length direction of the first ventilation pipe, and the plurality of ventilation nozzles are communicated with the second ventilation pipes."

[0004] Based on the above patent for the pulse bag filter, when the filter bag needs to be cleaned of accumulated dust, the pulse jet assembly sprays high-pressure gas, and the accumulated dust detaches from the filter bag. At this time, the dust settling assembly works, the blower inputs the air flow through the first ventilation pipe into the second ventilation pipes, and the second ventilation pipes output the air flow to the dust removal chamber through the ventilation nozzles. The air flow takes away the dust suspended inside the dust removal chamber, and at the same time, due to the action of the air flow and negative pressure, part of the accumulated dust on the surface of the filter bag is taken away, enhancing the dust cleaning effect.

[0005] Based on the above patent for the pulse bag filter, when the filter bag needs to be cleaned of accumulated dust, the pulse jet assembly sprays high-pressure gas, and the accumulated dust detaches from the filter bag. At this time, the dust settling assembly works, the blower inputs the air flow through the first ventilation pipe into the second ventilation pipes, and the second ventilation pipes output the air flow to the dust removal chamber through the ventilation nozzles. The air flow takes away the dust suspended inside the dust removal chamber, and at the same time, due to the action of the air flow and negative pressure, part of the accumulated dust on the surface of the filter bag is taken away, enhancing the dust cleaning effect. However, for cleaning the filter bag, only through the air flow and negative pressure, the whole filter bag cannot be cleaned thoroughly. The cleaning effect of this method is definitely not as comprehensive as disassembling the whole filter bag from inside the dust collector for cleaning. Therefore, the optimization for cleaning the whole filter bag is not perfect enough. Summary of the Utility Model

Several groups of arc grooves 7 are respectively opened at both ends of the inner walls of several through grooves 6. There are several groups of connecting blocks 9, and two connecting blocks 9 are symmetrically arranged in each group. Several groups of connecting blocks 9 are respectively slidably arranged on the inner walls of several groups of arc grooves 7;

[0041] Please refer to Figure 3 , the auxiliary assembly is arranged on the fixed plate 5 and used in cooperation with the sliding assembly, and is used to reduce the operation difficulty of manual installation and disassembly.
