Description

Technical Field

[0001] This utility model relates to the field of pulse cleaning technology, specifically a pulse cleaning dust removal device. Background Technology

[0002] Pulse jet dust collectors are highly efficient purification devices primarily used to remove dust particles from gases. Their working principle involves a fan drawing in dusty gas, which adheres to a filter medium (such as a filter bag or cartridge). Compressed air is then injected to remove the dust adhering to the filter medium. Pulse jet dust collectors offer advantages such as high purification efficiency, large gas handling capacity, stable performance, long filter bag life, ease of operation, and minimal maintenance.

[0003] Most existing pulse jet dust collectors lack a structure for cleaning the inner wall of the dust collector chamber during use. As a result, a lot of dust easily adheres to the inner wall of the dust collector chamber during use and cannot be removed by the pulse jet. After long-term use, this will affect the pulse jet cleaning effect and dust removal efficiency to a certain extent. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or existing pulse cleaning dust removal devices, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a pulse cleaning dust removal device. During operation, the impeller rotates under the action of the drive motor, causing the air pump to draw dust into the dust collection box through the hose. Larger dust particles fall into the dust hopper first under the action of gravity, while smaller dust particles adhere to the filter cloth. The purified air is discharged through the outlet pipe. Simultaneously, the impeller drives the first pulley to rotate, and under the action of the transmission belt, the first pulley drives the second pulley to rotate, causing the connecting rod to drive the worm gears at both ends to rotate. Through the cooperation of the worm gears and worm wheels, multiple reciprocating screws rotate synchronously, and through threaded connections... The scraper moves up and down and back and forth inside the dust collector to scrape off the dust adhering to the inner wall of the dust collector. When the dust accumulates to a certain level, the pulse valve is opened, and the jet pipe quickly inflates the filter cloth in the second fixed frame, causing the dust adhering to the filter cloth to fall into the dust hopper. This solves the problem that most existing pulse cleaning dust collectors do not have a structure to clean the inner wall of the dust collector box during use. This makes it easy for a lot of dust to stick to the inner wall of the dust collector box during use, which cannot be removed by pulse. After a long period of use, this will affect the pulse cleaning effect and dust removal effect to a certain extent.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A pulse cleaning dust removal device includes a dust collection box, a dust hopper fixedly connected to the bottom of the dust collection box, an external sealing plug connected to the bottom of the dust hopper, a first fixed frame fixedly connected to the middle of the outer side of the dust collection box, a dust suction component disposed on the top of the first fixed frame, a cover plate fixedly connected to the top of the dust collection box, a dust removal component disposed inside the dust collection box, a plurality of reciprocating screws longitudinally movably connected inside the dust collection box, a worm gear fixedly connected to one end of each reciprocating screw through the top of the cover plate, a scraper threadedly connected to the outer side of each reciprocating screw, both ends of the scraper being provided with reciprocating threaded holes, a connecting rod transversely movably connected to the top of the cover plate, a worm fixedly connected to both ends of the connecting rod, the worm meshing with the worm gear, and one end of the worm connected to the dust suction component.

[0012] In a preferred embodiment of the pulse cleaning and dust removal device of this utility model, the dust removal component includes a pulse valve, which is fixedly connected to one side of the dust removal box. The input end of the pulse valve is connected to an external compressed air package, and the output end of the pulse valve is fixedly connected to multiple jet pipes. An air outlet is provided at the bottom of each jet pipe.

[0013] In a preferred embodiment of the pulse cleaning dust removal device of this utility model, a fixing plate is fixedly connected to the bottom of the cover plate, the fixing plate is provided with multiple air holes, an external threaded boss is provided at the bottom of the air holes, a second fixing frame is threaded to the outer side of the external threaded boss, an internal thread is provided at the top of the second fixing frame, multiple fixing rods are fixedly connected to the bottom of the second fixing frame, and a filter cloth is fixedly connected between the multiple fixing rods, the filter cloth is provided with multiple filter holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The impeller rotates under the action of the drive motor, causing the air pump to draw dust into the dust collector through the hose. Larger dust particles fall into the ash hopper first under the action of gravity, while smaller dust particles adhere to the filter cloth. The purified air is discharged through the outlet pipe. Simultaneously, the impeller drives the first pulley to rotate, and under the action of the transmission belt, the first pulley drives the second pulley to rotate, causing the connecting rod to drive the worm gears at both ends to rotate. Through the cooperation of the worm gears and worm wheels, multiple reciprocating screws rotate synchronously, and through the threaded connection, the scraper moves in the dust removal process. The internal lifting and reciprocating motion of the chamber scrapes away the dust adhering to the inner wall of the dust collector. When the dust accumulates to a certain level, the pulse valve is opened, and the jet pipe quickly inflates the filter cloth in the second fixed frame, causing the dust adhering to the filter cloth to fall into the ash hopper. This solves the problem that most existing pulse cleaning dust collectors do not have a structure to clean the inner wall of the dust collector chamber during use. This makes it easy for a lot of dust to stick to the inner wall of the dust collector chamber during use, which cannot be removed by pulse. After a long period of use, this will affect the pulse cleaning effect and dust removal effect to a certain extent. Attached Figure Description

As a result, when existing pulse dust collectors are in use, a lot of dust easily adheres to the inner wall of the dust collector box and cannot be removed by pulse. After a long period of use, this will affect the pulse cleaning effect and dust removal effect to a certain extent.
