Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector cleaning technology, specifically to an auxiliary cleaning device for a bag filter. 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 and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas.
[0003] Currently, existing baghouse dust collectors typically require periodic cleaning of their filter bags during operation. This allows the dust accumulated on the outer walls of the filter bags to fall into the dust collection box below. Consequently, the dust collection box also needs to be cleaned. However, during the cleaning process, the dust inside the dust collection box is easily stirred up, making the manual cleaning operation environment quite harsh.
[0004] To address the aforementioned problems, this application proposes an auxiliary dust removal device for baghouse dust collectors. Utility Model Content
[0005] To address the problems in related technologies, this utility model provides an auxiliary dust removal device for baghouse dust collectors, which can effectively suppress dust flying in the dust collection box, improve the dust removal working environment, and enhance dust removal efficiency.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] An auxiliary cleaning device for a bag filter includes a dust collector body, a partition chamber, and an auxiliary cleaning component. Filter bags are installed in the inner cavity of the dust collector body, and a pulse air blowing component is installed above the filter bags. The bottom end of the dust collector body is connected to the partition chamber, and the bottom end of the partition chamber is connected to a dust collection box. The auxiliary cleaning component is installed in the dust collection box.
[0008] The auxiliary cleaning component includes atomizing tubes, two of which are symmetrically installed in the ash collection box. Atomizing nozzles are connected to the side walls of the atomizing tubes. The outlets of the atomizing nozzles are horizontally positioned. One end of the atomizing tube passes through the right side wall of the ash collection box and is connected to an inlet pipe. One end of a main pipe is connected to the right side wall of the inlet pipe. The other end of the main pipe is connected to the outlet of a water pump. The inlet pipe of the water pump extends into a water storage tank. An electrically controlled three-way valve is installed on the main pipe. A wall cleaning device is connected to the upper end of the electrically controlled three-way valve.
[0009] As a further embodiment of this utility model, the wall cleaning device includes a water spray pipe, which is installed on the four walls of the inner cavity of the ash collection box. The right end of the water spray pipe passes through the right side wall of the ash collection box and is connected to a water supply pipe. The bottom wall of the water supply pipe is connected to the upper end of an electrically controlled three-way valve.
[0010] As a further embodiment of this utility model, a nozzle is connected to the side wall of the water spray pipe, and the water outlet end of the nozzle is inclined toward the inner wall of the ash collection box.
[0011] As a further embodiment of this utility model, the pulse air blowing assembly includes an air inlet pipe, which is connected to an external air source. The right end of the air inlet pipe is connected to an air storage chamber, and an instrument is installed on the air inlet pipe. The upper end of the air storage chamber is connected to a pulse module, and an air outlet pipe is connected to the side wall of the pulse module.
[0012] As a further embodiment of this utility model, an air jet pipe is connected to the bottom wall of the air outlet pipe, and the air jet pipe extends into the filter bag.
[0013] As a further embodiment of this utility model, the outer wall of the left end of the dust collector body is connected to an air outlet, and the outer wall of the right end of the dust collector body is connected to an air inlet.
[0014] As a further embodiment of this utility model, a sealing cover is installed at the bottom of the ash collection box via a locking mechanism.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This utility model utilizes a dust collector body, a partition chamber, and auxiliary cleaning components working in concert. When cleaning the filter bags, dust on the outer wall of the filter bags first falls into the lower partition chamber, and then into the dust collection box. During this process, the water pump operates, and the electrically controlled three-way valve operates simultaneously, connecting the inlet pipe and the main pipe. The water pump then sends water from the water storage tank through the inlet pipe into the atomizing pipe, and then sprays it out from the atomizing nozzle, atomizing the passing dust and suppressing dust from flying. After the filter bags are cleaned, the sealing cover at the bottom of the dust collection box is opened to release the dust. Because the dust has undergone atomization, it no longer flies, thus improving the cleaning environment and increasing cleaning efficiency. When it is necessary to clean the dust adhering to the inner wall of the dust collection box, the electrically controlled three-way valve operates, the inlet pipe is closed, and the main pipe is connected to the water supply pipe, allowing water to enter the spray pipe and then spray from the nozzle onto the inner wall of the dust collection box, thereby cleaning the inner wall of the dust collection box.
[0017] 2. The partition compartment of this utility model allows for a certain space between the ash collection box and the filter bag, thereby preventing the atomizing nozzle from affecting the filter bag during operation. Attached Figure Description

[0027] According to an embodiment of the present invention, an auxiliary dust removal device for a bag filter is provided.
[0028] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, an auxiliary cleaning device for a bag filter includes a dust collector body 1, a partition chamber 2, and an auxiliary cleaning component 3. A filter bag 4 is installed in the inner cavity of the dust collector body 1, and a pulse air blowing component 5 is installed above the filter bag 4. An air outlet 15 is connected to the left outer wall of the dust collector body 1, and an air inlet 16 is connected to the right outer wall of the dust collector body 1. The bottom end of the dust collector body 1 is connected to the partition chamber 2, and the bottom end of the partition chamber 2 is connected to a dust collection box 6. The auxiliary cleaning component 3 is installed inside the dust collection box 6. The auxiliary cleaning component 3 includes an atomizing tube 7, two atomizing tubes 7 are symmetrically installed inside the dust collection box 6, and an atomizing nozzle 8 is connected to the side wall of the atomizing tube 7. The outlet of the atomizing nozzle 8 is horizontally positioned, and one end of the atomizing tube 7 passes through... An inlet pipe 9 is connected to the right side wall of the ash collection box 6. One end of a main pipe 10 is connected to the right side wall of the inlet pipe 9. The other end of the main pipe 10 is connected to the outlet of a water pump 11. The inlet pipe of the water pump 11 extends into the water storage tank 12. An electrically controlled three-way valve 13 is installed on the main pipe 10. The upper end of the electrically controlled three-way valve 13 is connected to a wall cleaning device 14. The wall cleaning device 14 includes a spray pipe 141. The spray pipe 141 is installed on the four walls of the inner cavity of the ash collection box 6. The right end of the spray pipe 141 passes through the right side wall of the ash collection box 6 and is connected to a water supply pipe 142. The bottom wall of the water supply pipe 142 is connected to the upper end of the electrically controlled three-way valve 13. A nozzle 143 is connected to the side wall of the spray pipe 141. The outlet of the nozzle 143 is inclined towards the inner wall of the ash collection box 6. The dust collector body 1, the partition chamber 2, and the auxiliary cleaning component 3 work together. When cleaning the filter bags 4, the dust on the outer wall of the filter bags 4 first falls into the lower partition chamber 2, and then into the dust collection box 6. During this process, the water pump 11 operates, and the electrically controlled three-way valve 13 operates simultaneously, connecting the inlet pipe 9 and the main pipe 10. Then, the water pump 11 sends water from the water storage tank 12 through the main pipe 10 and the inlet pipe 9 into the atomizing pipe 7, and then sprays it out from the atomizing nozzle 8, which can atomize the passing dust and suppress dust from flying. After the filter bag 4 is cleaned, open the sealing cover 17 at the bottom of the dust collection box 6 to release the dust. Since the dust has been atomized, it no longer flies, which can improve the dust cleaning environment and improve the dust cleaning efficiency. When it is necessary to clean the dust attached to the inner wall of the dust collection box 6, the electric three-way valve 13 is activated, the inlet pipe 9 is closed, and the main pipe 10 is connected to the water supply pipe 142, so that the water can enter the water spray pipe 141 and then spray from the nozzle 143 onto the inner wall of the dust collection box 6, thereby cleaning the inner wall of the dust collection box 6.
[0029] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 4 and Figure 5 As a further embodiment of this utility model, the pulse air blowing assembly 5 includes an air inlet pipe 51, which is connected to an external air source.

Additionally, the pulse module 54 can easily control the airflow into the air outlet pipe 55 and the jet pipe 56.
[0030] In one embodiment, please refer to the appendix to the specification. Figure 1 , Figure 2 and Figure 5 As a further embodiment of this utility model, a sealing cover 17 is installed at the bottom of the ash collection box 6 via a locking mechanism. In use, the sealing cover 17 is removed via the locking mechanism to facilitate the discharge of dust from the ash collection box 6.
[0031] Working process: During use, dust-laden gas enters the dust collector body 1 through the inlet 16, then enters the filter bag 4 for filtration, and is discharged from the outlet 15. When cleaning the filter bag 4, the pulse module 54 controls the airflow in the air storage chamber 52 to enter the outlet pipe 55 and the jet pipe 56, completing the air blowing operation on the filter bag 4. This causes the dust on the outer wall of the filter bag 4 to fall into the lower partition chamber 2, and then into the dust collection box 6. During this process, the water pump 11 operates, and the electrically controlled three-way valve 13 operates simultaneously, connecting the inlet pipe 9 and the main pipe 10. Then, the water pump 11 pumps water from the water storage tank 1... Water from pipe 2 is fed into atomizing pipe 7 through main pipe 10 and inlet pipe 9, and then sprayed out from atomizing nozzle 8. This atomizes the passing dust and suppresses dust from flying. After the filter bag 4 is cleaned, the sealing cover 17 at the bottom of the dust collection box 6 is opened to release the dust. When it is necessary to clean the dust attached to the inner wall of the dust collection box 6, the electric three-way valve 13 is activated, the inlet pipe 9 is closed, and the main pipe 10 is connected to the water supply pipe 142, so that water can enter the water spray pipe 141 and then be sprayed from the nozzle 143 onto the inner wall of the dust collection box 6, thereby cleaning the inner wall of the dust collection box 6.
