Description

Technical Field

[0001] The utility model relates to long-bag low-pressure pulse dust removal equipment, belonging to the technical field of dust removal equipment. Background Art

[0002] The long bag low pressure pulse dust collector is an advanced and efficient bag dust removal equipment. It is a large dust removal equipment with large air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, easy maintenance and small footprint.

[0003] According to the announcement number CN212790182U, a low-pressure long-bag pulse bag dust removal equipment is disclosed, including a base, a top seat is arranged above the base, a slot is arranged between the base and the top seat, a dust removal seat is arranged inside the slot, a fixed seat is arranged inside the dust removal seat, a filter element is connected to the bottom end of the fixed seat, one side of the fixed seat extends to the outside of the dust removal seat and is provided with a connecting port, sealing rings are arranged at the top and bottom ends of the dust removal seat, and a circulation pipe is arranged at one end of the base. The beneficial effect is that: through the provision of a circulation pipe, a fan and an outer cover, the circulation pipe is connected to the base and the top seat. When in use, the fan is running to draw the filtered exhaust gas from the top seat back into the base for circulation, thereby improving its filtering effect. The provision of the outer cover, which is located on the inner wall of the base and rotatably connected to the base, prevents the exhaust gas entering through the air inlet from directly entering the circulation pipe. When the above device is in use, although the device can be disassembled and installed, thereby facilitating maintenance of the internal equipment, disassembly and installation are inconvenient, resulting in poor maintenance efficiency. At the same time, when the cloth bag is pulsed for dust removal, dust falls on the inner wall of the base. After long-term use, a large amount of dust is easily adhered to the inner wall of the base, which requires manual cleaning, making the device less practical. Utility Model Content

[0024] Example 1 Please refer to Figure 1-Figure 6 , the utility model provides a technical solution:

[0025] A long bag low-pressure pulse dust removal device, comprising a shell 1, an air inlet pipe 2 is fixedly provided on the lower part of one side of the shell 1, a sewage pipe 3 is fixedly provided on the lower part of the other side of the shell 1, cylinders 4 are fixedly provided on the upper outer walls of both sides of the shell 1, and the output end of the cylinder 4 is fixedly connected to a cover body 5, a support plate 6 is fixedly provided on the upper inner wall of the shell 1, a wind plate 7 is provided on the top of the support plate 6, and a plurality of filter elements 8 are fixedly provided in a circular array at the bottom end of the wind plate 7, and the bottom ends of the filter elements 8 extend to the bottom of the support plate 6, an air supply pipe 19 is fixedly provided on the top of the wind plate 7, an exhaust pipe 10 is fixedly provided on the front side of the wind plate 7, and the front end of the exhaust pipe 10 extends to the front side of the shell 1, a fan 11 is fixedly provided on the inner wall of the top end of the cover body 5, an air supply pipe 2 12 is fixedly connected to the output end of the fan 11, and a sealing sleeve 13 matching the air supply pipe 19 is fixedly provided at the bottom end of the air supply pipe 2 12.

[0026] Specifically, Figure 1-Figure 6 As shown, the air inlet pipe 2, the sewage pipe 3 and the air supply pipe 9 are all provided with solenoid valves, and a motor 14 is fixedly embedded in the lower part of the shell 1. The output end of the motor 14 is fixedly connected to a rotating shaft 15, and the top of the rotating shaft 15 extends into the shell 1. The rotating shaft 15 is fixedly provided with a connecting rod 16 in an array, and the other end of the connecting rod 16 is fixedly connected to a scraper rod 17, and the side of the scraper rod 17 away from the connecting rod 16 is in conflict with the inner wall of the side adjacent to the shell 1, and a plurality of through grooves matching the filter element 8 are opened in an annular array on the support plate 6. The rotating shaft 15 is driven to rotate by the motor 14, so that the rotating shaft 15 drives the scraper rod 17 to rotate through the connecting rod 16, so that the lower inner wall of the shell 1 can be cleaned by the scraper rod 17.

[0027] Specifically, Figure 1-Figure 6As shown, a sleeve rod 19 is fixedly provided on the upper outer wall of the rear side of the shell 1, and a sliding rod 20 is slidably embedded in the top end of the sleeve rod 19. The top end of the sliding rod 20 is fixedly connected to the bottom end of the cover body 5. A limit block 21 is slidably provided inside the sleeve rod 19, and the bottom end of the sliding rod 20 is fixedly connected to the top end of the limit block 21. When the cover body 5 moves, the cover body 5 will drive the sliding rod 20 and the limit block 21 to move, and the sliding rod 20 and the limit block 21 can play a role of limiting support for the cover body 5.

[0028] Example 2 Please refer to Figure 1-Figure 6 The difference between this embodiment and embodiment 1 is that a pressure ring 18 is fixedly provided at the bottom end of the cover body 5, and the bottom end of the pressure ring 18 is tightly in contact with the top end of the wind plate 7.

[0029] Working principle of the utility model: when in use, after the filter element 8 passes through the through groove on the support plate 6, the wind plate 7 is placed on the support plate 6. At this time, the cylinder 4 drives the cover body 5 to move downward, so that the wind plate 7 is pressed and fixed by the pressure ring 18, and the sealing sleeve 13 is sleeved on the air supply pipe 9. At this time, the exhaust gas enters the housing 1 through the intake pipe 2, and then enters the wind plate 7 after being filtered by the filter element 8, and is then discharged through the exhaust pipe 10. When it is necessary to clean the filter element 8, the solenoid valve on the air supply pipe 9 is closed at this time, and then the air is transported to the wind plate 7 by the fan 11, and then the filter element 8 is blown and cleaned, so that the dust on the filter element 8 falls into the housing 1. At this time, the motor 14 drives the rotating shaft 15 to rotate, so that the rotating shaft 15 drives the scraper rod 17 to rotate through the connecting rod 16, so that the lower inner wall of the housing 1 can be cleaned by the scraper rod 17, so that the dust is discharged through the sewage pipe 3.
