Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment technology, and in particular to a pulse dust removal device for mineral powder processing. Background Technology

[0002] Dust-laden airflow in mineral powder processing is generally treated by pulse bag dust collectors. Dust-laden gas is introduced through the feed pipe, filtered through the outer surface of the bag, and then clean gas is discharged while dust is trapped. When the resistance increases, compressed air is released from the gas cylinder and sprayed in the opposite direction through the nozzle to blow the bag, causing it to expand and shake off the dust layer, thus achieving dust removal.

[0003] As the high-pressure gas propagates downward from the bag opening, it gradually depressurizes due to friction and expansion. The impact energy received at the bottom of the bag is significantly reduced, resulting in insufficient cleaning intensity in the bottom area of ​​the bag filter, causing dust to accumulate continuously. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the impact energy at the bottom of the bag is significantly attenuated due to the downward propagation of high-pressure gas from the bag opening, resulting in insufficient dust removal intensity in the bottom area of ​​the bag dust collector. Therefore, a pulse dust collector for mineral powder processing is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: a pulse dust removal device for mineral powder processing, comprising a device body, wherein an inlet pipe and an outlet pipe are respectively connected to the device body, and the device body is also equipped with a separation mechanism capable of separating mineral powder from the dust therein. The separation mechanism includes a partition fixedly installed inside the device body, with several bag filters installed at the bottom of the partition. A gas cylinder is fixedly installed on the device body, and a gas supply pipe is connected to the gas cylinder. One end of the gas supply pipe extending into the interior of the device body is connected to several spray pipes. The device body is also equipped with auxiliary components that can improve the dust removal effect of the bag filters, as well as an installation mechanism that can disassemble and replace the bag filters.

[0006] As a further description of the above technical solution: the auxiliary component includes a lifting frame that is slidably mounted on the main body of the device, a plurality of fixed rods that are fixedly mounted on the lifting frame, and a ring that is set on the fixed rods through a connecting rod, and the connecting rods and the fixed rods are threadedly connected.

[0007] As a further description of the above technical solution: the ring and connecting rod are located inside the bag filter, and the rubber ball is set on the bag filter by the first spring and is located below the ring.

[0008] As a further description of the above technical solution: a driving component is also assembled on the partition plate; The drive component includes a fixed frame symmetrically mounted on the partition plate, a threaded rod rotatably mounted on the fixed frame, a synchronous belt connecting to a pulley, the pulley being coaxially mounted with the threaded rod, and a servo motor fixedly mounted on the device body.

[0009] As a further description of the above technical solution: the lifting frame is threadedly installed between several threaded rods, one end of which is fixedly connected to the output end of the servo motor.

[0010] As a further description of the above technical solution: the installation mechanism includes several conical frames connected and installed on the partition plate, the limiting block is set on the conical frame by a second spring, and the first conical block and the second conical block are respectively set on the bag filter dust collector.

[0011] As a further description of the above technical solution: one side of the limiting block is provided with an inclined surface, and the limiting block is located between the first conical block and the second conical block, and the inclined surfaces on the first conical block and the second conical block are arranged in opposite directions.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The separation mechanism filters dust from mineral powder using a bag filter, while simultaneously using gas cylinders, air pipes, and nozzles to emit high-pressure gas for pulse dust removal. The high-pressure gas gradually depressurizes as it moves within the bag filter. By incorporating auxiliary components, including a lifting frame, rings, rubber balls, and spring structures, mechanical vibration assists in cleaning the filter bags during pulse jet cleaning, effectively improving cleaning efficiency and achieving overall cleaning of the bag filter. The installation mechanism employs a conical frame and a limiting block. The limiting block protrudes radially under the action of a second spring, locking between the first and second conical blocks to form a reverse inclined self-locking surface. During installation, pushing upwards automatically locks the mechanism; during disassembly, gently pulling downwards releases the locking mechanism. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 7 This embodiment provides a pulse dust removal device for mineral powder processing, including a device body 10. The device body 10 is connected to a feed pipe 11 and a discharge pipe 12. Mineral powder can be conveyed into the device body 10 through the feed pipe 11. The conveyed mineral powder will rise due to the suction of the discharge pipe 12. As the mineral powder rises, it will pass through a bag filter 22. The bag filter 22 will filter the dust in the mineral powder. The filtered mineral powder will be discharged through the discharge pipe 12. The device body 10 is also equipped with a separation mechanism 20 that can separate the mineral powder from the dust in it. The separation mechanism 20 includes a partition 21 fixedly installed inside the device body 10. Several bag filters 22 are installed at the bottom of the partition 21. The bag filters 22 are existing technology and can filter dust from the mineral powder. A gas cylinder 23 is fixedly installed on the device body 10. A gas supply pipe 24 is connected to the gas cylinder 23. An electrically controlled valve is installed on the gas supply pipe 24, and several nozzles 25 are connected to one end of the gas supply pipe 24 extending into the device body 10. The nozzles 25 correspond to the bag filters 22. The device body 10 is also equipped with auxiliary components to improve the dust removal efficiency of the bag filters 22. The bag filter 22 is equipped with component 26 and an installation mechanism 30 that allows for disassembly and replacement of the bag filter 22. After a period of use, the dust adsorbed on the surface of the bag filter 22 will gradually increase. At this time, the mineral powder will no longer be transported. The high-pressure air stored inside the gas cylinder 23 will be used to stabilize the airflow and deliver it to the air supply pipe 24. At this time, the electric control valve will open, and the high-pressure gas will be ejected through the nozzle 25 on the air supply pipe 24, allowing the high-pressure air to enter the interior of the bag filter 22 and form a pulse impact force, causing the filter bags in the bag filter 22 to expand instantly, shaking off the attached dust and achieving dust removal. The fallen dust will accumulate at the bottom of the device body 10, and can be cleaned by opening the box door at the bottom of the device body 10.

[0017] Reference Figure 4 - Figure 6 Specifically, in order to achieve comprehensive dust removal for the bag filter 22, an auxiliary component 26 is provided. The auxiliary component 26 includes a lifting frame 261 that is slidably mounted on the device body 10, and several fixed rods 262 that are fixedly mounted on the lifting frame 261. The lifting frame 261 can drive the fixed rods 262 to rise and fall. A ring 263 is mounted on the fixed rods 262 through a connecting rod 264. The ring 263 can rise and fall through the connecting rod 264 and the fixed rods 262. The connecting rod 264 and the fixed rod 262 are threadedly connected. The ring 263 can be separated from the fixed rod 262 by rotating the connecting rod 264.

[0018] In more detail, the circular ring 263 and the connecting rod 264 are located inside the bag filter 22. The rubber ball 265 is mounted on the bag filter 22 via the first spring 266 and is located below the circular ring 263. When the bag filter 22 is used for dust removal, high-pressure gas is injected inside the bag filter 22. However, as the high-pressure gas travels a greater distance inside the bag filter 22, the impact force on the bag filter 22 decreases. The lifting frame 261 can be lowered by the driving component 267, and the lifting frame 261 will push the fixed rod 262 and the connecting rod 264 when it descends, making... The ring 263 will also descend, and as it descends, it will squeeze the rubber balls 265 on both sides. At this time, the rubber balls 265 will twist through the first spring 266. The reciprocating ring 263 will continuously squeeze the rubber balls 265. After the rubber balls 265 lose contact with the ring 263, they will reset due to the reaction force of the first spring 266 and collide with the bag filter 22, causing the bag filter 22 to vibrate. This will play an auxiliary role in cleaning the bottom of the bag filter 22, and together with the high-pressure gas, achieve overall cleaning of the bag filter 22.

[0019] Reference Figure 5 Specifically, in order to enable the lifting frame 261 to be raised and lowered, a drive component 267 is also installed on the partition 21. The drive component 267 includes a fixed frame 2671 symmetrically mounted on the partition plate 21, a threaded rod 2672 rotatably mounted on the fixed frame 2671, a timing belt 2673 connecting pulleys, the pulleys being coaxially mounted with the threaded rod 2672, and the two pulleys and the threaded rod 2672 being synchronously rotated through the meshing transmission of the timing belt 2673. A servo motor 2674 is fixedly mounted on the device body 10.

[0020] In more detail, the lifting frame 261 is threaded between several threaded rods 2672. The lifting frame 261 can be raised and lowered by the forward and reverse rotation of the several threaded rods 2672. One end of one of the threaded rods 2672 is fixedly connected to the output end of the servo motor 2674. The servo motor 2674 can drive the threaded rod 2672 connected to it to rotate. Through the meshing transmission of the synchronous belt 2673, the several threaded rods 2672 can rotate synchronously, thereby enabling the lifting frame 261 to rise and fall.

[0021] Reference Figure 7Specifically, in order to disassemble and replace the bag filter 22, an installation mechanism 30 is provided. The installation mechanism 30 includes several conical frames 31 connected and installed on the partition plate 21. The limiting block 32 is set on the conical frame 31 by the second spring 33. The limiting block 32 can be reset by the reaction force of the second spring 33. The first conical block 34 and the second conical block 35 are respectively set on the bag filter 22.

[0022] More specifically, the limiting block 32 has an inclined surface on one side, and the limiting block 32 is located between the first conical block 34 and the second conical block 35. The inclined surfaces on the first conical block 34 and the second conical block 35 are arranged oppositely. When the bag filter 22 needs to be replaced, by pushing the bag filter 22 upward, the second conical block 35 will press against the inclined surface of the limiting block 32 after rising, causing the limiting block 32 to retract. As the bag filter 22 rises, the limiting block 32 will then contact the inclined surface of the second conical block 35 through the reaction force of the second spring 33, clamping the second conical block 35. At this time, by lowering the bag filter 22, the bag filter 22... The first conical block 34 descends and closely contacts the second conical block 35. At this time, the second conical block 35 also descends with the first conical block 34. The inclined surface of the second conical block 35 will press the limiting block 32 again, causing it to retract. Since the first conical block 34 and the second conical block 35 are in a merged state, after the second conical block 35 and the limiting block 32 are separated, the first conical block 34 will continue to press the limiting block 32 until they separate, thereby completing the disassembly of the bag filter 22 from the conical frame 31. The limiting block 32 is reset by the reaction force of the second spring 33. Then, rotating the connecting rod 264 can separate it from the fixed rod 262, thus not obstructing the disassembly of the bag filter 22.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
