Technical Field
[0001] This utility model relates to the field of concrete processing technology, and in particular to a novel pulse jet cleaning device for a bag filter dust collector in a mixing plant. Background Technology
[0002] Chinese patent document CN210522040U discloses a baghouse dust collector for an asphalt concrete mixing plant. The collector includes a body with an air inlet pipe at the bottom and an exhaust pipe at the top. A replaceable, flat-laid cloth bag is located between the air inlet and exhaust pipes inside the body. A cleaning brush is positioned below the cloth bag, adhering closely to its lower surface, and can move laterally back and forth across the body. This invention facilitates cleaning of the cloth bag by ensuring the cleaning brush contacts the lower surface of the bag and allows for regular cleaning of the bag's lower surface. This prevents excessive dust accumulation on the bag, which could hinder air purification, and thus provides more effective dust removal.
[0003] The bag filter dust collector of the above-mentioned asphalt concrete mixing plant still has particulate dust remaining inside the equipment after the filter bags are cleaned. Due to the gas flow, the particulate dust will still clog the filter bags. Therefore, this problem can be improved. Utility Model Content

[0023] Please see Figure 1-5This utility model provides a technical solution: a novel pulse jet cleaning device for a bag filter in a mixing plant, comprising a base plate 1, a horizontal plate 5, and a dust collection structure 8. A housing 2 and a cyclone dust collector 17 are fixedly installed on the top of the base plate 1. An air inlet is provided on the left side of the housing 2, and an exhaust pipe 20 is fixedly installed on the right side of the cyclone dust collector 17.

[0024] A discharge pipe 18 is fixedly installed at the bottom of the housing 2. A connecting pipe 19 is fixedly installed on the right side of the discharge pipe 18. One end of the connecting pipe 19 extends into the interior of the cyclone dust collector 17. A partition 3 is fixedly installed on the inner wall of the housing 2. A round opening is provided on the partition 3 and a filter cartridge 4 is fixedly installed on its inner wall. Two sets of raised rings 9 distributed vertically are fixedly installed on the outer wall of the filter cartridge 4. A transparent cover plate 16 is provided on the front side of the housing 2. A pad is fixedly installed on the outer wall of the transparent cover plate 16. A stud is fixedly installed on the front side of the housing 2. The stud passes through the pad and is threaded with a nut. A hole is provided on the housing 2. The structure has a slotted hole with a vertical tube 6 located inside it. One end of the vertical tube 6 is fixedly connected to a rotary joint 15 and communicates with its interior. A hydraulic rod 14 is fixedly installed on the top of the housing 2. The free end of the hydraulic rod 14 passes through the housing 2 and is fixedly connected to the horizontal plate 5. The drive structure includes a connecting rod 10, gears 11, and a motor 12. The connecting rod 10 is rotatably installed on the bottom of the horizontal plate 5, and the vertical tube 6 is rotatably installed on the horizontal plate 5. There are two sets of gears 11, which are respectively fixedly installed on the outer wall of the vertical tube 6 and the other end of the connecting rod 10. The two sets of gears 11 are meshed. The motor 12 is fixedly installed on the top of the horizontal plate 5. The rotating shaft of 12 passes through the horizontal plate 5 and is fixedly connected to the connecting rod 10. The transparent cover plate 16 is removed and the port of the filter bag is tied between the two sets of convex rings 9 on the filter cartridge 4. The equipment introduces the air in the mixing plant into the box 2 through the air inlet. The filter bag automatically intercepts and collects particulate dust, and then introduces it into the cyclone dust collector 17 through the feed pipe 18 and the connecting pipe 19. Then, the cyclone dust collector 17 is controlled to process the dust. When the filter bag is blocked, the air supply pipe is connected to the rotary joint 15 and the hydraulic rod 14 is controlled to drive the horizontal plate 5 to move downward, while the motor 1 is controlled. The rotation of the drive linkage 10 drives the rotation of the vertical pipe 6 and the jet pipe 7 through two sets of gears 11. The air input into the vertical pipe 6 is sprayed out through the jet pipe 7, which can then clean the filter bag. The filter bag can be installed and filter out dust and exhaust gas in the dust-laden gas. The particulate dust is automatically collected and processed by the filter bag, and the dust enters the cyclone dust collector for secondary filtration. This can purify the air in the mixing plant and also perform jet cleaning inside the filter bag to prevent particulate dust from clogging the filter bag, thus enhancing the practicality of the device.
[0025] The dust collection structure 8 includes a housing 81, a chamber 82, a shroud 83, an exhaust fan 84, a filter plate 85, a circular tube 86, a flexible hose 87, and an exhaust pipe 88.

The shroud 83 is fixedly installed on the inner wall of the housing 81. The exhaust fan 84 is fixedly installed on the top inner side of the housing 81. The filter plate 85 is fixedly installed on the inner wall of the chamber 82. Circular tubes 86 are fixedly installed on the outer walls of both the housing 81 and the chamber 82.

Four sets of reinforcing blocks 13 are fixedly installed on the outer wall of the vertical pipe 6 and are distributed in a ring at equal intervals. The reinforcing blocks 13 are fixedly installed on the top of the housing 81 to control the start of the induced draft fan 84. Then, air is drawn into the chamber 82 through the hose 87 and two sets of round pipes 86. The particulate dust is then adsorbed into the chamber 82 through the air intake 89. This can adsorb and collect the particulate dust raised when the filter bag is blown inside, thus avoiding the situation where particulate dust remains in the box 2 and will still clog the filter bag due to the air flow. At the same time, the chamber 82 is easy to disassemble, making it easy to clean the particulate dust collected inside.
[0026] Working principle: The transparent cover plate 16 is removed and the port of the filter bag is tied between the two sets of convex rings 9 on the filter cartridge 4. The equipment introduces the air in the mixing station into the box 2 through the air inlet. The filter bag automatically intercepts and collects the particulate dust, and then introduces it into the cyclone dust collector 17 through the feed pipe 18 and connecting pipe 19. Then, the cyclone dust collector 17 is controlled to process the dust. When the filter bag is blocked, the air supply pipe is connected to the rotary joint 15 and the hydraulic rod 14 is controlled to drive the horizontal plate 5 to move downward. At the same time, the motor 12 is controlled to drive the connecting rod 10 to rotate. Then, the vertical pipe 6 and the jet pipe 7 are driven to rotate through the two sets of gears 11. The air input into the vertical pipe 6 is sprayed out through the jet pipe 7, and then the filter bag can be cleaned. At the same time, the induced draft fan 84 is started, and then air is sucked into the bin 82 through the hose 87 and two sets of round pipes 86. Then, the particulate dust is adsorbed into the bin 82 through the air intake 89.
