Description

Technical Field

[0001] This utility model relates to the field of pollution control equipment technology, specifically a bag pulse dust collector that is easy to clean and used for pollution control. Background Technology

[0002] In industrial production in factories such as metallurgy, cement, and machinery processing, dusty gases are often present at the work site. In order to carry out pollution prevention and control, factories need to purify dusty gases and recover dusty materials. Bag pulse dust collectors are a commonly used high-efficiency dust removal equipment. After dusty gases enter the equipment, they are filtered by the filter bags inside the device, and clean gases are discharged.

[0003] In traditional baghouse pulse dust collectors, when too much dust accumulates on the filter bags, compressed air is blown away from the bags by activating the pulse valve. However, due to the varying distances between the air inlet and the filter bags, and the fact that the bottom of the filter bags is usually loose, the high-pressure air can cause the filter bags to be squeezed, resulting in incomplete cleaning of impurities on the inner walls of the filter bags.

[0026] In the embodiment, the top shell 3 is fixed on the top end of the top cover 2 by screws, the top cover 2 is fixed on the top end of the cylinder 1 by screws, and the storage box 12 is fixed on the bottom end of the cylinder 1 by screws. The screwing method can facilitate the assembly of the top shell 3, the top cover 2 and the storage box 12 on the cylinder 1.

[0027] In this embodiment, the adapter pipe is simply installed around the top of the cylinder 1.

[0028] In this embodiment, a motor 10 is fixedly installed on one side of the cylinder 1, and a housing 14 is fixedly installed inside the cylinder 1. A rotating shaft 15, which is inserted into the dust collector bag 6, is rotatably installed in the middle part of the housing 14. A cleaning rod 18 is provided on one side of the rotating shaft 15. A brush that contacts the inner wall of the dust collector bag 6 is provided on the cleaning rod 18. A driven bevel gear located inside the housing 14 is provided at the bottom end of the rotating shaft 15. A drive shaft 16 that penetrates the cylinder 1 is provided at the output end of the motor 10. A drive bevel gear that cooperates with the driven bevel gear is provided at one end of the drive shaft 16. The inner wall of the dust collector bag 6 can be cleaned by the cleaning rod 18, so that the dust collector bag 6 can be cleaned more thoroughly.

[0029] In this embodiment, the motor 10 is a servo motor.

[0030] Place the cylinder 1 in the predetermined position and ensure its stability. Fix the top cover 2 to the top of the cylinder 1 with screws. Then fix the top shell 3 to the top of the top cover 2 with screws. At the same time, install the exhaust pipe 4 on the top of the top shell 3. Install the air inlet pipe 5 on one side of the cylinder 1 and the air inlet pipe 11 on the other side. Install the adapter pipe around the top of the cylinder 1 and ensure that the air inlet pipe 11 is connected to multiple air outlet pipes 17 through the adapter pipe.

[0031] The storage box 12 is fixed to the bottom of the cylinder 1 with screws. The motor 10 is fixed to one side of the cylinder 1. The box 14 is fixed inside the cylinder 1. The rotating shaft 15 is rotatably set in the middle part of the box 14, ensuring that one end of it is inserted into the dust collector bag 6. A cleaning rod 18 is installed on one side of the rotating shaft 15. A brush is fixed on the cleaning rod 18 so that it can contact the inner wall of the dust collector bag 6. A driven bevel gear is installed at the bottom of the rotating shaft 15. The drive shaft 16 of the motor 10 passes through the cylinder 1. A drive bevel gear that cooperates with the driven bevel gear is installed at one end of the drive shaft 16. The annular base 7 and the annular top seat 8 of the dust collector bag 6 are inserted into the cavity 13 in the middle part of the top cover 2. By rotating the annular top seat 8, it is threadedly connected to the top cover 2, thus completing the installation of the dust collector bag 6. The rotation operation can be assisted by the lever at the top of the annular top seat 8.

[0032] Dust-laden gas enters the cylinder 1 through the inlet pipe 5. Due to the filtering effect of the dust collector bag 6, the dust is trapped on the inner surface of the dust collector bag 6. The purified gas is discharged to the outside through the exhaust pipe 4. As time goes by, the dust trapped on the dust collector bag 6 increases. The motor 10 can be turned on periodically to clean the dust collector bag 6. The cleaned dust falls into the collection box 12 to ensure the continuous and efficient operation of the equipment.

[0033] When the dust collector bag 6 needs to be cleaned, the air inlet pipe 11 is connected to the designated fan. After the fan is started, it can blow air from multiple air outlets, which can provide a back-blowing effect for the dust collector bag 6. During this process, the annular base 7, annular top seat 8 and support rod 9 can provide a support for the dust collector bag 6, so that the high-pressure air will not cause the dust collector bag 6 to be squeezed, and the impurities on the inner wall of the dust collector bag 6 will be cleaned more thoroughly. The cleaned impurities will fall into the storage box 12 for storage.

[0034] Start motor 10. Motor 10 is a servo motor that can precisely control speed and direction. Motor 10 drives drive shaft 16 to rotate. Drive bevel gear on drive shaft 16 drives driven bevel gear to rotate, thereby causing rotating shaft 15 to drive cleaning rod 18 and brush to rotate, so as to clean the inner wall of dust collector bag 6 more thoroughly.
