Description

Technical Field

[0001] This utility model relates to the technical field of filter bag dust collectors, and in particular to a dust removal structure for a negative pressure internal filter bag dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. After dust collection, the filter bags in the baghouse dust collector need to be cleaned.

[0003] Most of the baghouse dust collectors currently in use have complex structures, are inconvenient to operate, and have poor dust removal effects. At the same time, existing baghouse dust collectors are prone to dust accumulation, lack an auxiliary dust removal structure, and have insufficient shock absorption and stability. Utility Model Content

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a dust removal structure for a negative pressure internal filtration bag filter, comprising: a housing 1, with an air inlet 101 and an air outlet 102 respectively on both sides of the housing 1; a blower 2 installed on one side of the air inlet 101; a filter assembly 3 installed at one end of the blower 2; four grooves 4 symmetrically distributed on the inner wall of the housing 1; a vibration assembly 5 installed on the inner wall of the grooves 4; a mounting plate 6 installed on the inner wall of the housing 1; and multiple symmetrically distributed filter bags 7 installed below the mounting plate 6. An electromagnetic pulse valve 8 is installed above the filter bag 7. A blow pipe 9 is fixedly connected to the lower end of the electromagnetic pulse valve 8. A spray plate 10 is fixedly connected to the lower end of the blow pipe 9. Multiple nozzles 11 are fixedly connected below the spray plate 10. The multiple nozzles 11 are all located above the multiple filter bags 7, and the multiple nozzles 11 and the filter bags 7 correspond to each other vertically. A ash hopper 12 is provided below the shell 1. Two support frames 13 are fixedly connected to the lower part of the shell 1, and the two support frames 13 are symmetrically arranged. A shell plate 14 is rotatably connected to the front end of the shell 1 via a hinge. An observation window is installed at the front end of the shell plate 14.

[0026] The vibration assembly 5 includes a sliding cavity 501 fixedly connected to the inner wall of the groove 4. A slide rod 502 is slidably connected to the inner wall of the sliding cavity 501. A spring 503 is fixedly connected to one end of the slide rod 502 inside the sliding cavity 501, and a slider 504 is fixedly connected to the other end of the slide rod 502 away from the spring 503. A vibration motor 505 is fixedly connected to the inner top wall of the groove 4. The vibration motor 505 is located directly above the slider 504, and one side of the slider 504 is fixedly connected to the outer wall of the mounting plate 6. The vibration assembly 5 facilitates the shaking off of dust from the filter bag 7.

[0027] The filter assembly 3 includes a frame 301 rotatably connected to the air inlet of the blower 2, and a filter screen 302 is provided on the inner wall of the frame 301. The filter assembly 3 prevents large impurities from entering the blower 2.

[0028] Working principle: During use, the blower 2 draws dust-containing gas into the housing 1 through the air inlet 101. During the intake, the filter screen 302 performs preliminary filtration of the gas, removing larger particles. Then, the filtered gas enters the filter bag 7, which further filters out fine dust particles. After the filter bag 7 has been used for a long time, it needs to be cleaned. The vibration motor 505 can be started to make it vibrate, causing the slider 504 to slide in the groove 4. At the same time, when the slider 504 slides, the spring 503 at one end of the slider 502 will increase the vibration effect of the mounting plate 6, thereby shaking off the dust from the filter bag 7 on the mounting plate 6. In addition, when there is too much dust on the filter bag 7, the electromagnetic pulse valve 8 can be activated to deliver compressed air to the spray plate 10 through the blowpipe 9. The compressed air is then sprayed onto the filter bag 7 through the nozzle 11 on the spray plate 10, thereby blowing off the dust on the surface of the filter bag 7, achieving the purpose of cleaning. The blown-off dust falls into the dust hopper 12 for subsequent cleaning.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
