Technical Field

[0001] This invention relates to the field of dust collector technology, and in particular to a dust collection device and its usage method. Background Technology

[0002] Pulse jet baghouse dust collectors are baghouse dust collectors that use pulse jet cleaning. They employ compartment-based, off-flow pulse jet cleaning technology, overcoming the shortcomings of conventional pulse jet dust collectors and compartment-based reverse-air dust collectors. They offer strong cleaning capability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small footprint, stable and reliable operation, and good economic benefits. They are suitable for purifying dust-laden gases and recovering materials in industries such as metallurgy, building materials, cement, machinery, chemicals, power, and light industry.

[0003] In existing pulse jet baghouse dust collectors, insufficient pulse jet force can lead to incomplete cleaning of dust adhering to the filter bags, and the damp, dust-laden gas can soak the filter bags, causing dust to clump together and become impossible to remove, thus affecting the operation of the equipment.

[0004] Therefore, this solution proposes a dust removal device and its usage method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a dust removal device and its usage method, which can solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust removal device, comprising a dust collector, wherein a filter bag is disposed inside the dust collector, a partition is fixedly connected to the inner wall of the dust collector, a first motor is fixedly connected to the surface of the partition, a threaded rod is fixedly connected to the output shaft of the first motor, a connecting rod is threadedly connected to the surface of the threaded rod, a sleeve is fixedly connected to the side of the connecting rod, the sleeve is hollow inside, and a roller brush is rotatably connected inside the sleeve, the roller brush being located outside the filter bag.

[0007] Preferably, a cord is wound around the surface of the roller brush, one end of which slides through the sleeve and extends to the outside of the sleeve. A first spring is fixedly connected to the surface of the roller brush, and the other end of the first spring is fixedly connected to the surface of the sleeve. The end of the cord away from the roller brush is fixedly connected to the partition.

[0011] Preferably, a toothed ring is fixedly connected to the surface of the roller brush, and the toothed ring meshes with a first gear.

[0012] Preferably, a collection box is provided at the bottom of the dust collector.

[0013] Preferably, a second motor is provided at the bottom of the dust collector, the output end of the second motor is fixedly connected to a first rotating shaft, a second gear is fixedly connected to the surface of the first rotating shaft, a first grinding cylinder is sleeved on the surface of the first rotating shaft, and the first rotating shaft rotates through the collection box and extends to the outside.

A third gear is fixedly connected to the side of the second rotating shaft, and a second grinding cylinder is fixedly connected to the surface of the second rotating shaft. The second gear and the third gear mesh.

[0015] A method of using a dust removal device includes the following steps: S. Transporting external gas into the interior of the dust collector; S. The residual material in the gas is treated by a dust collector; S. The residual material adhering to the cloth bag is cleaned by the up-and-down reciprocating movement and rotation of the roller brush. S. The cleaned residue falls into the inside of the collection box, and is then crushed into powder by the first and second grinding cylinders.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) The waste material recyclable dust collector and its usage method make the loose rope wrapped around the surface of the roller brush, so that the roller brush can rotate. The roller brush can not only move up and down to clean the cloth bag along the texture, but also rotate around the cloth bag to clean it. Therefore, it can better clean the dust attached to the cloth bag. When humid dust-laden gas enters the dust collector, it will clump on the cloth bag and is not easy to remove by air vibration. Therefore, this method can also clean the clumped dust very well.

[0017] (2) The waste material recyclable dust collector and its usage method: when the top of the sleeve moves, the first motor is started in reverse, so that the first motor drives the threaded rod to rotate in reverse, thereby causing the connecting rod to move downward.

[0018] (3) The waste material recyclable dust collector and its usage method make the meshing first gear rotate on the surface of the support column, drive the knocking rod to rotate, make the knocking rod knock the roller brush, and then make the roller brush shake, thereby making the cloth bag shake, and then shake off the dust on the cloth bag and the roller brush, thereby cleaning the cloth bag and the roller brush, maximizing the cleaning effect of dust and reducing the difficulty of cleaning.

[0019] (4) The waste material recyclable dust collector and its usage method: the output end of the second motor will drive the fixedly connected first rotating shaft to rotate, drive the fixedly connected first grinding cylinder to rotate, the rotation of the first rotating shaft will drive the second gear to rotate, thereby causing the meshing third gear to rotate, the rotation of the third gear will drive the second rotating shaft to rotate, thereby driving the second grinding cylinder to rotate, and thus crushing the agglomerated dust falling from the dust collector, and better collecting the dust.

[0022] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0023] Please see Figure 1-5 This invention provides a technical solution: a dust removal device and its usage method, comprising a dust collector 1, a filter bag 2 disposed inside the dust collector 1, a partition 15 fixedly connected to the inner wall of the dust collector 1, a first motor 3 fixedly connected to the surface of the partition 15, a threaded rod 4 fixedly connected to the output shaft of the first motor 3, a connecting rod 5 threadedly connected to the surface of the threaded rod 4, a sleeve 6 fixedly connected to the side of the connecting rod 5, the sleeve 6 being hollow inside, a roller brush 7 rotatably connected inside the sleeve 6, the roller brush 7 being located outside the filter bag 2, a rope 8 wound around the surface of the roller brush 7, one end of the rope 8 slidingly penetrating the sleeve 6 and extending to the outside of the sleeve 6, a first spring 9 fixedly connected to the surface of the roller brush 7, the other end of the first spring 9 fixedly connected to the surface of the sleeve 6, a pulley 10 disposed on the upper surface of the sleeve 6, the rope 8 contacting the pulley 10, and the end of the rope 8 away from the roller brush 7 fixedly connected to the partition 15.

[0024] The first motor 3 is started, and the output end of the first motor 3 drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 causes the threaded connecting rod 5 to move upward, which in turn moves the sleeve 6 upward, thereby causing the taut rope 8 to move upward and loosen the rope 8. At this time, the first spring 9, which is fixedly connected to the roller brush 7, begins to reset, causing the loosened rope 8 to wrap around the surface of the roller brush 7, thereby causing the roller brush 7 to rotate. The roller brush 7 can not only move up and down to clean the cloth bag 2 along the texture, but also rotate around the cloth bag 2 to clean it. Therefore, it can better clean the dust attached to the cloth bag 2. When humid dusty gas enters the dust collector 1, it will clump on the cloth bag 2 and is not easy to remove by air vibration. Therefore, this method can also effectively clean the clumped dust.

[0025] When the sleeve 6 moves to the top, the first motor 3 is started in reverse, causing the first motor 3 to drive the threaded rod 4 to rotate in the opposite direction, which in turn causes the connecting rod 5 to move downward. When the connecting rod 5 moves downward, it pulls the rope 8, which in turn pulls the rope 8 wrapped on the surface of the roller brush 7, causing the roller brush 7 to rotate in the opposite direction and clean the cloth bag 2.

[0026] The pulley 10 facilitates the reversal of the direction of the rope 8, thereby making it easier to pull the rope 8.

[0027] A support column 13 is fixedly connected to the surface of the sleeve 6. A first gear 12 is rotatably connected to the surface of the support column 13. A striking rod 18 is rotatably connected to the bottom of the first gear 12. One end of the striking rod 18 contacts the roller brush 7. A second spring 17 is movably sleeved on the striking rod 18. The end of the second spring 17 near the first gear 12 is fixedly connected to the first gear 12, and the end of the second spring 17 away from the first gear 12 is fixedly connected to the striking rod 18. A toothed ring 11 is fixedly connected to the surface of the roller brush 7. The toothed ring 11 meshes with the first gear 12.

[0028] When the roller brush 7 rotates, it drives the toothed ring 11 to rotate, which in turn causes the meshing first gear 12 to rotate on the surface of the support column 13. This, in turn, drives the striking rod 18 to rotate, causing the striking rod 18 to strike the roller brush 7. This causes the roller brush 7 to vibrate, which in turn causes the cloth bag 2 to vibrate, thus shaking off the dust from the cloth bag 2 and the roller brush 7. This effectively cleans the cloth bag 2 and the roller brush 7, maximizing the cleaning effect and reducing the difficulty of cleaning.

[0029] When the striking rod 18 comes into contact with the roller brush 7, it will cause the striking rod 18 to rotate, which will cause the second spring 17 to deform and swing back and forth to repeatedly strike the roller brush 7. At the same time, since the striking rod 18 is made of a deformable material, it can bend, which will cause the striking rod 18 to continue to rotate.

[0030] A collection box 16 is provided at the bottom of the dust collector 1. A second motor 19 is provided at the bottom of the dust collector 1. A first rotating shaft 22 is fixedly connected to the output end of the second motor 19. A second gear 21 is fixedly connected to the surface of the first rotating shaft 22. A first grinding cylinder 14 is sleeved on the surface of the first rotating shaft 22. The first rotating shaft 22 rotates through the collection box 16 and extends to the outside. A second rotating shaft 24 is rotatably connected inside the collection box 16. The second rotating shaft 24 extends through the collection box 16 to the side. A third gear 20 is fixedly connected to the side of the second rotating shaft 24. A second grinding cylinder 23 is fixedly connected to the surface of the second rotating shaft 24. The second gear 21 and the third gear 20 mesh.

[0031] When the second motor 19 is started, its output will drive the fixedly connected first rotating shaft 22 to rotate, which in turn drives the fixedly connected first grinding cylinder 14 to rotate. The rotation of the first rotating shaft 22 will drive the second gear 21 to rotate, which in turn drives the meshing third gear 20 to rotate. The rotation of the third gear 20 will drive the second rotating shaft 24 to rotate, which in turn drives the second grinding cylinder 23 to rotate, thereby crushing the agglomerated dust falling from the dust collector 1 and collecting the dust more effectively.

[0032] A method of using a dust removal device includes the following steps: S1. External gas is delivered into the interior of dust collector 1; S2. The residual material in the gas is processed by dust collector 1; S3. The residual material adhering to the cloth bag 2 is cleaned by the up-and-down reciprocating movement and rotation of the roller brush 7. S4. The cleaned residue falls into the collection box 6, and is crushed into powder by the first grinding cylinder 14 and the second grinding cylinder 23.

[0033] Working principle: The first motor 3 is started, and its output drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 causes the threaded connecting rod 5 to move upward, which in turn moves the sleeve 6 upward, thereby causing the taut rope 8 to move upward and loosen. At this time, the first spring 9, which is fixedly connected to the roller brush 7, begins to reset, causing the loosened rope 8 to wrap around the surface of the roller brush 7, thus causing the roller brush 7 to rotate. The roller brush 7 can not only move up and down to clean the cloth bag 2 along the texture, but also rotate around the cloth bag 2 to clean it, thus better cleaning the dust attached to the cloth bag 2. The first motor 3 is started in reverse, causing the threaded rod 4 to rotate in the opposite direction, which in turn causes the connecting rod 5 to move downward. When the connecting rod 5 moves downward, it pulls the rope 8, which in turn pulls the rope 8 wrapped around the surface of the roller brush 7, causing the roller brush 7 to rotate in the opposite direction to clean the cloth bag 2.

[0034] When the roller brush 7 rotates, it drives the toothed ring 11 to rotate, which in turn causes the meshing first gear 12 to rotate on the surface of the support column 13. This causes the striking rod 18 to rotate, which in turn strikes the roller brush 7, causing the roller brush 7 to vibrate. This, in turn, causes the cloth bag 2 to vibrate, thus shaking off the dust from the cloth bag 2 and the roller brush 7, thereby cleaning the cloth bag 2 and the roller brush 7.

[0035] When the second motor 19 is started, its output will drive the fixedly connected first rotating shaft 22 to rotate, which in turn drives the fixedly connected first grinding cylinder 14 to rotate. The rotation of the first rotating shaft 22 will drive the second gear 21 to rotate, which in turn drives the meshing third gear 20 to rotate. The rotation of the third gear 20 will drive the second rotating shaft 24 to rotate, which in turn drives the second grinding cylinder 23 to rotate, thereby crushing the agglomerated dust falling from the dust collector 1.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
