Detailed Implementation

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a dust removal device for a bag filter includes a housing 1. An air inlet pipe 2 is provided on one side of the housing 1, and an air outlet pipe 3 is provided on the other side of the housing 1. Several filter bags 4 are arranged in a rectangular array inside the housing 1. Each filter bag 4 has a connecting pipe 5 on its surface. The sides of each filter bag 4 are interconnected by short pipes. Two sides of the filter bags 4 in the matrix are connected to a three-way pipe 6, and one end of each three-way pipe 6 is connected to a positioning pipe 7. One positioning pipe 7 is connected to the air inlet pipe 2, and the other positioning pipe 7 is connected to the air outlet pipe 3. A support plate 8 is provided on the front of the housing 1. An air pump 9 is provided on the top of the support plate 8. A hose 10 is connected to the air outlet of the air pump 9, and a horizontal pipe 11 is connected to one end of the hose 10.

[0023] The specific problem addressed in this embodiment is to solve the problem that, in order to increase filtration performance, the filter bag is stacked and pleated, and some dust accumulates inside the gaps between the pleats, and vibration makes it impossible to completely remove the dust from inside the gaps between the pleats. This invention utilizes a high-pressure gas pump 9 to deliver high-pressure gas through a hose 10, a horizontal pipe 11, and a central pipe 12 to a connecting pipe 5 inside the filter bag 4, forming a high-pressure gas backflushing system. This system effectively removes dust accumulated deep within the folds of the filter bag 4, solving the problem that traditional vibration methods cannot thoroughly remove dust from inside the folds and significantly improving dust removal efficiency. The inner box 14, installed at an angle inside the bottom box 13, works in conjunction with the vibration force of the two side vibration motors 15 and the elastic support of the springs 16 to achieve automatic conveying and sieving of dust under vibration, solving the problem of dust accumulation and difficulty in discharge. Vibration sieving improves the automation level of dust handling. The steel wire filter screen 18 structure at the bottom of the inner box 14 enables particle size classification of collected dust, solving the problem of inconvenient subsequent processing of mixed dust. Larger particles are discharged into the triangular box 19 through the discharge chute 17, while smaller particles pass through the filter screen 18 and fall into the trapezoidal box 20, improving the classification efficiency of dust collection.

[0024] Several central through pipes 12 are equidistantly arranged on the side of the horizontal pipe 11. One end of each central through pipe 12 penetrates the interior of the housing 1 and is connected to the connecting pipe 5. A bottom box 13 is provided at the bottom of the housing 1. An inclined inner box 14 is provided inside the bottom box 13. Vibration motors 15 are provided on both sides of the inner box 14. In this specific embodiment, when the dust removal device of the bag filter is implemented, the dust-laden gas enters the housing 1 from the inlet pipe 2 and is filtered by the matrix-arranged filter bags 4. Each filter bag 4 is interconnected with the connecting pipe 5 on its surface and the short pipe on its side to form a filter network. The filtered clean gas then passes through the filter bags. The air is discharged through the outlet pipe 3 on the other side; when dust removal is required, the air pump 9 on the support plate 8 is started, and the generated high-pressure gas is delivered to the horizontal pipe 11 through the hose 10, and then blown back into the connecting pipe 5 inside the filter bag 4 through the central pipe 12 set at equal intervals, so as to realize the powerful back-blowing dust removal of the filter bag 4; the removed dust falls into the inclined inner box 14 in the bottom box 13, and the vibration force generated by the vibration motor 15 set on both sides of the inner box 14 promotes the conveying and screening of dust. The high-pressure gas back-blowing system realizes the deep dust removal of the filter bag 4, solves the problem of difficult dust removal of the pleated filter bag 4, and improves the dust removal efficiency.

[0025] In this specific embodiment, springs 16 are provided on the back and front end faces of the inner box 14. One end of each spring 16 is fixedly connected to the inner wall of the bottom box 13. A discharge groove 17 is provided in the middle of the front of the inner box 14. The inner bottom surface of the inner box 14 is a filter screen 18 made of steel wire. A triangular box 19 is provided on the front of the bottom box 13 and the discharge groove 17 is connected to the triangular box 19. A trapezoidal box 20 is provided at the bottom of the bottom box 13.

[0026] The inner box 14 is suspended inside the base box 13 by springs 16 set on the back and front end faces, forming an elastic support system. When the vibration motor 15 works, the inner box 14 vibrates in cooperation with the springs 16, accelerating the flow and screening of dust. The dust in the inner box 14 is sorted by size by the wire mesh 18. Larger particles are discharged from the discharge chute 17 on the front into the triangular box 19 under the action of vibration, while fine particles fall into the trapezoidal box 20 at the bottom through the filter 18. The automated conveying and screening of dust is realized through the coordinated vibration of the springs 16 and the vibration motor 15, which improves the processing efficiency.

[0027] In this specific embodiment, the air pump 9 is connected to the central pipe 12 via the hose 10 and the horizontal pipe 11 to form a high-pressure gas cleaning system;

[0028] The air pump 9 serves as a high-pressure air source, delivering gas to the horizontal pipe 11 via the connection of the hose 10. The central pipes 12, which are evenly distributed on the horizontal pipe 11, ensure that the high-pressure gas is evenly distributed to the connecting pipes 5 of each filter bag 4, forming a systematic dust removal airflow channel. The connection of the air pump 9, hose 10, and horizontal pipe 11 constitutes a complete high-pressure gas dust removal system, ensuring the reliability and uniformity of the dust removal operation.

[0029] In this specific embodiment, the filter screen 18 is disposed at the bottom of the inner box 14 to classify dust particles by size;

[0030] The steel wire filter 18 installed at the bottom of the inner box 14 screens the falling dust during vibration. Larger particles are trapped on the surface of the filter 18 and gradually move towards the discharge chute 17, while fine particles fall directly through the mesh, realizing automatic classification of particulate matter. The screening function of the filter 18 enables dust to be collected according to particle size, which provides convenience for subsequent processing.

[0031] In this specific embodiment, the triangular box 19 is disposed on the front of the bottom box 13 to collect larger dust particles discharged from the discharge chute 17;

[0032] The triangular box 19 is positioned on the front of the bottom box 13 and connects with the discharge chute 17. Large dust particles that have been screened in the inner box 14 are continuously discharged from the discharge chute 17 under vibration and directly enter the triangular box 19 for storage. The triangular box 19 enables the centralized collection of large dust particles, avoiding dust accumulation and secondary dust generation.

[0033] In this specific embodiment, the trapezoidal box 20 is disposed at the bottom of the base box 13 to collect fine dust particles falling through the filter screen 18;

[0034] The trapezoidal box 20 is located at the bottom of the base box 13, directly below the filter screen 18. Fine dust particles passing through the filter screen 18 fall naturally into the trapezoidal box 20 under the action of gravity and are collected. The trapezoidal box 20 realizes the special collection of fine dust particles and improves the dust classification and processing function.

[0035] Working principle: Dust-laden gas enters the housing 1 through the inlet pipe 2 and is filtered by the matrix-arranged filter bags 4. Clean gas is discharged from the outlet pipe 3. During dust removal, the high-pressure gas generated by the air pump 9 is blown in the opposite direction into the connecting pipe 5 inside the filter bag 4 through the hose 10, horizontal pipe 11 and central pipe 12 to achieve dust removal. The shaken dust falls into the inclined inner box 14 of the bottom box 13. Through the synergistic action of the vibration motor 15 and the spring 16, the dust is vibrated and screened. Larger particles enter the triangular box 19 through the discharge chute 17, while finer particles pass through the filter screen 18 at the bottom of the inner box 14 and fall into the trapezoidal box 20, completing the classification and collection of dust.

The power supply is also common knowledge in the field.
