Description

Technical Field

[0001] The invention relates to the technical field of industrial dust collectors, and in particular to a cartridge-type industrial dust collector for air purification. Background Art

[0002] With the acceleration of industrialization, air pollution is becoming increasingly serious, especially the large amount of harmful gases and dust generated in the industrial production process. These pollutants not only damage the environment, but also pose a threat to human health. Traditional industrial dust collectors mainly adopt filter bag design. This design has some limitations when dealing with dusty gases. First, the filter area of ​​the filter bag is limited, resulting in limited processing capacity, especially inefficient when dealing with large flow gases. Secondly, the filter bag is easy to break and clog, and needs to be frequently replaced and cleaned, which increases maintenance costs and operational complexity. Therefore, the development of industrial dust removal technology is crucial to improving air quality and protecting the environment.

[0003] Most of the existing cartridge-type industrial dust collectors place filter media inside the filter cartridge, and the filter media are mostly directly exposed to the outside, which can easily lead to rapid adsorption and saturation of the filter media, thereby reducing the purification effect. The filter media needs to be replaced, and the equipment must be stopped for replacement, affecting continuous operation. Summary of the invention

[0018] The first spring is fixedly mounted on the circular ring, and the top end of the first spring contacts the bottom end of the filter plate, and there is a gap between the top end of one side of the circular ring close to the filter plate and the bottom end of the filter plate.

[0019] As a further description of the above technical solution:

[0020] The through slot is located between the two groups of extension frames, the inclined block is located between the through slots, one side of the two inclined blocks is provided with an inclined surface, and the distance between the two inclined blocks is consistent with the distance between the two ends of the extension frame.

[0021] As a further description of the above technical solution:

[0022] The feeding assembly includes a feeding pipe fixedly mounted on the top of the cover plate, a guide frame symmetrically mounted on the top of the cover plate, a lifting block slidably connected to the guide frame, a second spring fixedly connected between the lifting block and the cover plate, sliders inserted on both sides of the feeding pipe, a material collection box fixedly mounted on the outer wall of the dust collector body, and a plurality of discharge ports opened on the inner wall of the dust collector body.

One end of the feed pipe is located in the circular groove and fits with one of the discharge ports.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. By setting up a filtering mechanism, the air is transported to the inside of the filter cartridge through the air intake pipe. At this time, the air will contact the filter screen on the top of the filter cartridge to filter large particles in the air for the first time. The groove on the top cover plate corresponds to one of the extension frames at this time, and the air is filtered for the second time through the filter medium on the top of the corresponding filter plate. Then the air passes through the filter plate and contacts the electrostatic dust removal component, and the impurities suspended in the air are adsorbed by the electrostatic dust removal component, and the air is discharged again through the filter screen at the bottom of the filter cartridge, achieving multiple purification effects. After the filter medium on the top of the filter plate has been used for a period of time, the corresponding filter medium will be saturated with adsorption, and the cover plate is driven to rotate by the servo motor to rotate the groove on the cover plate to the next extension frame, so that the clean and unused filter medium can adsorb and filter the air again to avoid local overload.

[0029] 2. While the cover plate rotates, one of the inclined blocks at its bottom will first contact one side of the extension frame and squeeze the extension frame, causing the extension frame to rotate downward, so that the top of the extension frame contacts and collides with the top of the ring, and the filter medium can slide through the ring into the discharge pipe through vibration, and then fall into the collection box for collection. As the cover plate rotates, the inclined block that first contacts the top of the extension frame will separate, and the extension frame will be reset by the reaction force of the first spring. The vibration during reset will prevent the filter medium remaining on the top of the extension frame from sticking to its surface, and then the other inclined block will contact and squeeze the top of the extension frame again, causing the extension frame to rotate downward again, which can discharge the used filter medium while preventing it from sticking to the top of the extension frame.

[0030] 3. After the cover plate rotates, the feed pipe rotates to the next discharge port and fits with it. Through the sensor on the corresponding discharge port, the valve at this discharge port can be opened, allowing the filter medium to enter the feed pipe through the discharge port, and then fall into the top of the filter plate through the feed pipe. When the filter medium passes through the feed pipe, the force brought by the descent squeezes the top inclined surface of the slider, so that the two sliders move to both sides to squeeze the lifting block, causing the lifting block to descend and collide with the top of the filter plate, and then the lifting block is reset by the second spring and squeezes the slider to reset, and it reciprocates in this way, thereby continuously hitting the top of the filter plate. When the filter plate is hit, it will also rotate slightly downward and then reset through the first spring. The vibration during the collision prevents the filter medium from accumulating in the middle of the filter plate, thereby replenishing the filter medium without stopping the entire device for replenishment.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1 - Fig.12As shown, the present invention provides: a cartridge-type industrial dust collector for air purification, comprising a dust collector body 10, on which an air inlet pipe 11 and an air outlet pipe 12 are arranged, air is transported to a filter cartridge 13 through the air inlet pipe 11, and then the purified air is discharged through the air outlet pipe 12, filter cartridges 13 are equidistantly installed inside the dust collector body 10, a filter mechanism 20 capable of purifying air is installed inside the filter cartridge 13, and an auxiliary mechanism 30 capable of replacing a filter medium for filtering air is installed on the filter mechanism 20;

[0049] The filter mechanism 20 includes a filter screen 21 symmetrically installed inside the filter cartridge 13 and capable of filtering the air. The filter screen 21 at the top of the filter cartridge 13 will perform a primary filtration on the air to filter out large particles of impurities in the air, and the filter screen 21 at the bottom of the filter cartridge 13 will filter the purified air again to improve the purification effect. An electrostatic dust removal component 22 capable of adsorbing impurities suspended in the air is installed inside the filter cartridge 13. A mounting seat 23 is fixedly installed inside the filter cartridge 13. A rotating component 24 capable of improving the air purification effect is installed on the top of the mounting seat 23. The electrostatic dust removal component 22 is a prior art, which can discharge and deposit negatively charged dust particles to the anode surface under the action of the electric field force, thereby adsorbing suspended impurities in the air.

[0050] The auxiliary mechanism 30 includes a circular ring 31 and a collecting box 32 fixedly mounted on the filter cartridge 13, a discharge pipe 33 is connected and installed between the circular ring 31 and the collecting box 32, and a tilting component 34 capable of discharging the filter medium and a feeding component 35 used in conjunction with the tilting component 34 to supplement the filter medium are provided on the mounting seat 23.

[0051] In further detail, the rotating assembly 24 includes a cover plate 241 rotatably mounted on the mounting seat 23, a plurality of filter plates 242 are hinged inside the mounting seat 23, and the plurality of filter plates 242 are equidistantly arranged in the mounting seat 23, an extension frame 243 is fixedly mounted on the top end of the filter plate 242, and a servo motor 244 is fixedly mounted on the bottom end of the mounting seat 23.

[0052] In further detail, the output end of the servo motor 244 passes through the mounting seat 23 and is connected to the cover plate 241. A groove with the same size as the extension frame 243 is opened on one side of the cover plate 241. The filter plate 242 is distributed in a ring shape on the mounting seat 23, and the cover plate 241 is driven to rotate by the servo motor 244.

[0053] In further detail, the electrostatic dust removal element 22 is located below the filter plate 242, and one end of the outlet pipe 12 extends to the interior of the dust collector body 10 and is located directly above the filter cartridge 13. The air pressure during exhaust through the outlet pipe 12 causes the air to move toward the interior of the filter cartridge 13. Filter holes are equidistantly provided on the filter plate 242, and a filter medium is provided on the top of the filter plate 242 corresponding to the groove. The filter medium is block-shaped and is an elastic polymer, and the diameter of the elastic polymer is larger than the filter hole.

[0054] like Figure 8 - Fig.12 As shown, the tilting assembly 34 includes a first spring 341 arranged between the filter plate 242 and the ring 31, and the filter plate 242 is supported by the first spring 341. A plurality of through grooves 342 are provided on the top of the mounting seat 23, and a tilting block 343 is fixedly installed on the bottom end of the cover plate 241. When the cover plate 241 rotates, one of the tilting blocks 343 at the bottom will first contact one side of the extension frame 243 and squeeze the extension frame 243, so that the extension frame 243 rotates downward, so that the top of the extension frame 243 contacts and collides with the top of the ring 31, and the filter medium can slide through the ring 31 into the discharge pipe 33 through vibration, and then fall into the collection box 32 for collection.

[0055] In further detail, the first spring 341 is fixedly mounted on the ring 31, and the top end of the first spring 341 contacts the bottom end of the filter plate 242. The filter plate 242 is supported by the first spring 341. There is a gap between the top end of the side of the ring 31 close to the filter plate 242 and the bottom end of the filter plate 242, so that the filter plate 242 can be rotated into an inclined surface and contact the top of the ring 31. At the same time, contacting the top of the ring 31 will also give a reaction force to the filter plate 242, so that the filter plate 242 vibrates when in contact, so that the filter medium on the top of the filter plate 242 can slide off.

[0056] In further detail, the through groove 342 is located between the two groups of extension frames 243, and the inclined block 343 is located between the through groove 342. An inclined surface is provided on one side of the two inclined blocks 343. The distance between the two inclined blocks 343 is consistent with the distance between the two ends of the extension frame 243. As the cover plate 241 rotates, the inclined block 343 that first contacts the top of the extension frame 243 will separate. At this time, the extension frame 243 is reset by the reaction force of the first spring 341. The vibration during the reset prevents the filter medium remaining on the top of the extension frame 243 from adhering to its surface. Then, the other inclined block 343 will contact and squeeze the top of the extension frame 243 again, causing the extension frame 243 to rotate downward again, allowing the residual filter medium to slide off again, which can remove the used filter medium while preventing it from adhering to the top of the extension frame 243.

[0057] In further detail, the feeding assembly 35 includes a feed pipe 351 fixedly mounted on the top of the cover plate 241, a guide frame 352 is symmetrically mounted on the top of the cover plate 241, a lifting block 353 is slidably connected to the guide frame 352, a second spring 354 is fixedly connected between the lifting block 353 and the cover plate 241, sliders 355 are inserted on both sides of the feed pipe 351, a feed box 356 is fixedly mounted on the outer wall of the dust collector body 10, and filter medium is stored in the feed box 356, and a plurality of discharge ports 357 are opened on the inner wall of the dust collector body 10.

[0058] The top of the filter plate 242 is then reset by the second spring 354 and the slider 355 is reset, and the top of the filter plate 242 is continuously reset by the second spring 354, and the slider 355 is reset by the second spring 354, and the slider 355 is reset by the second spring 354, and the top of the filter plate 242 is continuously ...

[0059] In further detail, a circular groove is provided on the inner wall of the dust collector body 10, and a plurality of discharge ports 357 and one end of the feed pipe 351 are all located in the circular groove. The number and position of the discharge ports 357 correspond to the filter plate (242), and the discharge ports 357 are connected to the collection box 356. A solenoid valve (not marked in the figure) is provided at the discharge port 357. After the feed pipe 351 is fitted with the discharge port 357, the valve is opened by controlling the solenoid valve. A power supply is provided on the outer wall of the dust collector body 10. The wires on the power supply pass through the dust collector body 10 and the filter cartridge 13 and are connected to the solenoid valve and the servo motor 244. At the same time, the operation of the servo motor 244 and the solenoid valve is controlled by the PLC, so that the filter medium inside the collection box 356 can enter the feed pipe 351. One end of the feed pipe 351 is located in the circular groove and fits with one of the discharge ports 357.

[0060] Working principle: When in use, air is transported to the inside of the filter cartridge 13 through the air inlet pipe 11. The air moves toward the inside of the filter cartridge 13 due to the air pressure during transport. At this time, the air first passes through the filter screen 21 at the top of the filter cartridge 13, and the large particles in the air are filtered by the filter screen 21 for the first time, and then the impurities are filtered for the second time through the filter plate 242 at the top of the filter plate 242;

[0061] Only one extension frame 243 will leak out through the groove on one side of the cover plate 241 at a time, and the air will contact the corresponding filter medium, and the impurities in the air will be adsorbed and filtered through the filter medium, and then the air will pass through the filter plate 242 and enter the electrostatic dust removal element 22, and the negatively charged dust particles will discharge and deposit on the anode surface under the action of the electric field force, so as to adsorb the suspended impurities in the air, and then the air will be discharged from the filter screen 21 at the bottom of the filter cartridge 13 to another chamber, and then discharged through the outlet pipe 12;

[0062] After the filter medium has been purified for a period of time, the filter medium exposed to the outside will be saturated with adsorption. At this time, the servo motor 244 drives the cover plate 241 to rotate, so that the groove on the cover plate 241 rotates to the next filter plate 242, allowing the unused filter medium to be exposed to the air for purification. This cycle is repeated. Since there is always fresh filter medium available, the filtration efficiency of the entire system can be maintained.

[0063] When the cover plate 241 rotates, one of the inclined blocks 343 at the bottom thereof will first contact one side of the extension frame 243 and squeeze the extension frame 243, so that the extension frame 243 rotates downward, so that the top of the extension frame 243 contacts and collides with the top of the ring 31, and the filter medium can slide through the ring 31 into the discharge pipe 33 through vibration, and then fall into the collection box 32 for collection. As the cover plate 241 rotates, the inclined block 343 that first contacts the top of the extension frame 243 will separate, and at this time, the extension frame 243 is reset by the reaction force of the first spring 341, and the vibration during the reset will prevent the filter medium remaining on the top of the extension frame 243 from adhering to its surface, and then the other inclined block 343 will contact and squeeze the top of the extension frame 243 again, so that the extension frame 243 rotates downward again, allowing the residual filter medium to slide again, which can discharge the used filter medium while preventing it from adhering to the top of the extension frame 243.

[0064] After the cover plate 241 rotates, the delivery pipe 351 on the top thereof rotates to the next discharge port 357 and fits with it. The discharge port 357 is opened by the solenoid valve on the corresponding discharge port 357, allowing the filter medium to enter the delivery pipe 351 through the discharge port 357, and then fall through the delivery pipe 351 to the top of the filter plate 242 after discharge.

[0065] When the filter medium passes through the feed pipe 351, the force brought by the descent squeezes the top inclined surface of the slider 355, so that the two sliders 355 move toward both sides to squeeze the lifting block 353, so that the lifting block 353 descends and collides with the top of the filter plate 242, and then the lifting block 353 is reset by the second spring 354 and squeezes the slider 355 to reset, and so on, thereby continuously colliding with the top of the filter plate 242, and when the filter plate 242 is hit, it will also slightly rotate downward through the first spring 341 and then reset, and the vibration during the collision will prevent the filter medium from accumulating in the middle of the filter plate 242, so that the filter medium can be replenished without stopping the entire device for replenishment.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
