The fixed plate 4 is rectangular and made of metal material. The fixed plate 4 made of metal material has higher strength, is not easily deformed and damaged under force, and is more durable. A filter bag frame 5 is fixedly connected to the inner wall of the fixed plate 4, and the surface of the filter bag frame 5 is slidably connected to the inner wall of the partition board 3. A filter bag 6 is fixedly connected to the inner wall of the filter bag frame 5. A handle 7 is fixedly connected to the surface of the fixed plate 4. A switch fixing mechanism is arranged on the back of the dust collector main body 1. The switch fixing mechanism is composed of a hinge 8, a top cover 9, a lid lock 10, a limit shaft 11 and a fixed pad 12. The number of limit shafts 11 is multiple, and the multiple limit shafts 11 are symmetrically arranged with the vertical center line on the front surface of the top cover 9 as the axis of symmetry, used to limit the fixed plate 4 and improve the limit stability. The hinge 8 is fixedly connected to the back of the dust collector main body 1. The top cover 9 is hinged to the dust collector main body 1 through the hinge 8, and the top cover 9 overlaps with the top surface of the dust collector main body 1. The lid lock 10 is fixedly connected to the inner wall of the top cover 9. The limit shaft 11 is fixedly connected to the bottom surface of the top cover 9. The fixed pad 12 is fixedly connected to the bottom end of the limit shaft 11, and the bottom surface of the fixed pad 12 overlaps with the top surface of the fixed plate 4, used to open and close the dust collector main body 1, and at the same time facilitate pressing down the fixed plate 4, improve the use stability of the filter bag 6, and at the same time improve the replacement efficiency of the filter bag 6. An air inlet and outlet assembly is arranged on the surface of the dust collector main body 1. A pulse blowing mechanism is arranged above the dust collector main body 1. An ash discharge assembly is arranged inside the dust collector main body 1.

[0022] Specifically, the air inlet and outlet assembly consists of an air inlet 13 and an air outlet 14. The air inlet 13 is opened through the left side of the dust collector body 1, and the air outlet 14 is opened through the top surface of the top cover 9, which is used for the intake and exhaust of exhaust gas to facilitate continuous dust removal of exhaust gas.

[0023] Specifically, the pulse spraying mechanism consists of a spraying pipe 15, a connecting pipe 16 and an electromagnetic pulse valve 17. The spraying pipe 15 is fixedly connected to the inner wall of the top cover 9, the inner wall of the connecting pipe 16 is fixedly connected to the air inlet end of the spraying pipe 15, the electromagnetic pulse valve 17 is fixedly connected to the inner wall of the connecting pipe 16, and the electromagnetic pulse valve 17 is fixedly connected to the top surface of the top cover 9, which is used to control the intermittent spraying of compressed air to facilitate the dust removal work of the filter bag 6.

[0024] Specifically, the ash discharge assembly consists of an ash discharge pipe 18 and a solenoid valve 19. The ash discharge pipe 18 is fixedly connected to the inner wall of the dust collector body 1, and the solenoid valve 19 is fixedly connected to the inner wall of the ash discharge pipe 18, which is used to discharge the falling dust and facilitate centralized cleaning of the dust.

[0025] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0026] When in use: When in use, first connect the air inlet 13 to the exhaust pipe. After the exhaust gas enters the dust collector body 1 through the air inlet 13, the dust in the exhaust gas is filtered through the filter bag frame 5 and the filter bag 6. The filtered exhaust gas flows upward and is discharged through the air outlet 14. Connect the connecting pipe 16 to the compressed air, and intermittently open the electromagnetic pulse valve 17 to allow the compressed air to be sprayed through the spray pipe 15 to the filter bag 6 below. The dust adsorbed on the filter bag 6 can be cleaned by spraying, and the dust falls into the dust collector body 1 after cleaning. The dust can be collected and discharged through the ash discharge pipe 18 after the solenoid valve 19 is opened. When the filter bag 6 needs to be replaced and maintained, the cover lock 10 is opened and the top cover 9 is rotated to open by the hinge 8. The rotation of the top cover 9 drives the limit shaft 11 and the fixed pad 12 to flip upward and separate from the fixed plate 4. After the top cover 9 is opened, the handle 7 is grasped to drive the fixed plate 4 to move upward and separate from the partition plate 3. The movement of the fixed plate 4 drives the filter bag frame 5 and the filter bag 6 to move upward and separate from the dust collector body 1, and the filter bag 6 can be maintained and replaced.

[0027] In summary, for the pulse dust collector facilitating the maintenance of filter bags, waste gas enters the dust collector main body 1 through the air inlet and outlet assembly, the dust in the waste gas is filtered by the filter bag frame 5 and the filter cloth bag 6, and then the waste gas is discharged through the air inlet and outlet assembly. The pulse jet mechanism is used to control the compressed gas to spray into the interior of the filter cloth bag 6 to clean the dust. By opening the ash discharge assembly, the dust can be discharged. By opening the switch fixing mechanism to turn upwards and disengage from the fixing plate 4, the handle 7 is grasped to drive the fixing plate 4, the filter bag frame 5 and the filter cloth bag 6 to move upwards and disengage from the dust collector main body 1, so that the filter cloth bag 6 can be maintained and replaced. The goal of facilitating the rapid replacement and maintenance of the filter bags in the pulse dust collector is achieved, and the problem that the disassembly and maintenance work of the filter bags is very time-consuming and laborious due to the difficulty of disassembling the filter bag components in the existing pulse dust collectors is avoided, which is used to solve the problems raised in the above background technology.
