Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a pulse dust collector which is easy to clean. Background Art

[0002] Pulse dust collector is a method of removing dust attached to the filter medium (bag or filter cartridge) by blowing compressed air. Depending on the size of the dust collector, there may be several groups of pulse valves, which are controlled by a pulse controller or PLC. Each time a group of pulse valves is opened, the dust in the bag or filter cartridge it controls is removed, while the other bags or filter cartridges work normally. After a period of time, the next group of pulse valves is opened.

[0003] In the existing pulse dust collector, the blowing pipe is set just above the bag, and the high-pressure gas is ejected from the blowing pipe to expand the bag so as to separate the dust from the outer surface of the bag for cleaning. However, most of the dust attached to the surface of the bag will fall into the ash hopper, but a small part of the dust is still attached and cannot be removed;

[0004] The existing patent (Announcement No.: CN210278561U) discloses a pulse dust collector, including a body, a filter bag wrapped in a cylindrical frame, a cleaning ring sleeved on the outside of the filter bag, and bristles in contact with the outer wall of the filter bag on the inner wall of the cleaning ring, and a linear motor, which drives the cleaning ring to reciprocate up and down on the outside of the filter bag through a pull rod. The cleaning ring disposed outside the filter bag reciprocates to perform secondary cleaning to clean residual dust, thereby greatly improving the cleaning efficiency.

[0005] The existing patents provide solutions to the above problems. However, when the dust collector is performing dust removal, the dust will fall to the bottom of the dust collector under the action of gravity and accumulate, and it needs to be stopped for cleaning after a period of time. This dust cleaning method will not only greatly reduce the working efficiency of the dust collector, but also greatly increase the labor intensity of workers by using manual cleaning methods. Inconvenient operation can easily cause dust residue inside the dust collector, affecting the dust cleaning quality.

[0006] Therefore, a pulse dust collector which is easy to clean is proposed. Summary of the invention

[0032] The bracket 20 is distributed in an annular structure, and the cloth bag 8 is in a hollow cylindrical shape.

[0033] By adopting the above technical solution, when the pulse dust removal device is working, dust gas is first injected into the box body 1 through the air inlet pipe 4, and the dust gas will diffuse to the lower side of the box body 1 under the guidance of the wind shield 12, and then the dust in the box body 1 will be adsorbed by the cloth bag 8, and the heavier dust will fall under the action of gravity. The box body 1 fixes and rotates the support rod 7 through the support plate 6, so that the bracket 20 is fixed and supported by the support rod 7, and the bracket 20 supports the cloth bag 8 so that the cloth bag 8 remains in an expanded state, so that the dust can be better adsorbed by the cloth bag 8, thereby improving the removal efficiency of the dust collector.

[0034] Specifically, Figure 4 and Figure 5 As shown, the inner surface of the discharge hopper 2 is rotatably connected to a rotating shaft 13, and the outer surface of the rotating shaft 13 is fixedly connected to blades 14. The number of the blades 14 is four groups and they are distributed in a ring shape.

[0035] A discharge pipe 17 is fixedly connected to the lower end of the inner surface of the discharge hopper 2 , a second rotating shaft 15 is rotatably connected to the inner surface of the discharge hopper 2 , and a spiral blade 18 is fixedly connected to the outer surface of the second rotating shaft 15 .

[0038] By adopting the above technical scheme, the dust will contact the surface of the blade 14 during the falling process, and the dust will drive the blade 14 to flip under the action of gravity. The shaft 13 supports the blade 14 for rotation. As the shaft 13 drives the blade 14 to rotate, the shaken dust will fall on the surface of the guide plate 16 under the action of gravity, and slide into the discharge pipe 17 under the guidance of the guide plate 16. The blade 14 will contact the block 19 during the rotation process, and drive the shaft 2 15 to rotate through the block 19, thereby driving the spiral blade 18 to rotate through the shaft 2 15, so that the dust in the discharge pipe 17 is discharged to the outside of the discharge hopper 2 through the rotation of the spiral blade 18, thereby realizing automatic cleaning of the dust in the dust removal box, which can greatly reduce the residual dust in the dust removal box and greatly reduce the workload of manual cleaning.

[0039] Working principle: When the pulse dust removal device is working, dust gas is first injected into the box body 1 through the air inlet pipe 4. The dust gas will diffuse to the lower side of the box body 1 under the guidance of the wind shield plate, and then the dust in the box body 1 will be adsorbed by the cloth bag 8. The heavier dust will fall under the action of gravity. The box body 1 fixes and rotates the support rod 7 through the support plate 6, so that the bracket 20 is fixedly supported by the support rod 7. The bracket 20 supports the cloth bag 8 so that the cloth bag 8 remains in an expanded state, so that the dust can be better adsorbed through the cloth bag 8, thereby improving the dust removal quality of the dust collector. When the dust collector needs to be cleaned, the compressed air in the air compressor pipe 3 is put into the conduit 2 10 through the gate valve, and is guided to extend into the conduit 1 9 through the conduit 2 10, and then is sprayed into the cloth bag 8 from the nozzle 11 on the lower side of the conduit 1 9, and the cloth bag 8 is impacted by the pulse-like spraying of high-pressure gas, so that the cloth bag 8 is pulse-like shaken, thereby shaking off the dust on the surface of the cloth bag 8, greatly reducing The dust adheres to the surface of the bag 8, thereby improving the adsorption effect of the bag 8 while also greatly reducing the workload of cleaning the bag 8, thereby further improving the stability of the dust collector during operation. The dust will contact the surface of the blade 14 during the falling process, and the dust will drive the blade 14 to flip under the action of gravity. The shaft 13 supports the blade 14 for rotation. As the shaft 13 drives the blade 14 to rotate, the shaken-off dust will fall on the surface of the guide plate 16 under the action of gravity, and slide into the discharge pipe 17 under the guidance of the guide plate 16. The blade 14 will contact the block 19 during the rotation process, and drive the shaft 2 15 to rotate through the block 19, thereby driving the spiral blade 18 to rotate through the shaft 2 15, so that the dust in the discharge pipe 17 is discharged to the outside of the discharge hopper 2 through the rotation of the spiral blade 18, thereby realizing automatic cleaning of the dust in the dust collector box, thereby greatly reducing the residual dust in the dust collector box and greatly reducing the workload of manual cleaning.
