Description

TECHNICAL FIELD

[0001] The application relates to the technical field of dust collectors, in particular to a micro-power point type filter cartridge pulse dust collector. BACKGROUND

[0002] The pulse filter cartridge dust collector adopts a pulse blowing online dust cleaning mode, and the dust cleaning process is automatically controlled by a pulse control instrument, and users can adopt a time control mode to clean dust according to needs.

[0003] According to the search, the patent file with the announcement number CN216092751U discloses a double-filter cartridge pulse dust collector, which comprises a treatment tank, an air inlet, an air outlet and filter cartridges. The bottom inner wall of the treatment tank is fixedly connected with a filter plate. The filter cartridges are arranged in two and are fixedly connected to the filter plate. One end of the cleaning plate is slidably connected in the sliding groove, and the other end is rotatably connected with the screw rod through the threaded hole.

[0004] According to the related technology in the above, the inventor finds that at least the following problems exist in the technology. The filter cartridge lacks an internal cleaning function. The working principle of the filter cartridge dust collector is that dust-containing gas flows from the outside to the inside of the filter cartridge, and dust is intercepted on the outer surface of the filter cartridge. The cleaning cotton can only scrape the dust on the outermost layer of the filter cartridge, and has no effect on the dust embedded in the deep layer of the filter material and the dust accumulated in the internal folds of the filter cartridge. These deep dust can quickly block the filter cartridge, causing the filtration resistance to increase rapidly, the air volume to decrease sharply, and the dust removal efficiency to decrease rapidly or even fail. Therefore, a micro-power point type filter cartridge pulse dust collector is proposed to solve the problems in the above. SUMMARY

[0005] In view of the deficiencies of the prior art, in order to avoid filter cartridge blockage, the application provides a micro-power point type filter cartridge pulse dust collector, which has the advantages of micro-power efficient conversion, improved cleaning effect and the like, and solves the problem that the existing filter cartridge external scraping method cannot solve the dust in the filter cartridge.

[0006] The application provides a micro-power point type filter cartridge pulse dust collector, which adopts the following technical scheme:

[0007] A micro-power point type filter cartridge pulse dust collector, comprising a dust collector body, wherein the dust collector body comprises a shell and a filter cartridge which is detachably installed in the interior of the shell, and the bottom of the shell is provided with a cleaning mechanism extending into the shell and used for cleaning the filter cartridge, and a driving device used for driving the cleaning mechanism;

[0008] The driving device comprises an electric telescopic rod, a connecting seat is installed on the output end of the electric telescopic rod, a mounting table is fixed to the top side of the connecting seat, and a driving assembly is arranged on the side surface of the connecting seat and the bottom side of the shell;

[0009] The cleaning mechanism includes a transmission component disposed on the mounting platform and extending into the interior of the filter cartridge. The transmission component is used in conjunction with the drive component. A tapping component is provided on the side of the transmission component for use with the transmission component.

[0010] The striking assembly includes a mounting cylinder, inside which a striking rod extending outwards is reciprocated. One end of the striking rod is provided with a connector for connection to a transmission assembly, and a nozzle for use with the transmission assembly is installed inside the striking rod.

[0011] The mounting platform has a mounting rod that extends into the housing, and a scraper that is sleeved on the outside of the filter cartridge is fixed to the top of the mounting rod.

[0012] Optionally, the shell is hollow inside, and a partition is fixed on the inner wall of the top side of the shell to divide the interior of the shell into two spaces. Two air holes are opened on the side of the shell and distributed vertically, wherein the air holes on the top side are higher than the partition.

[0013] A cylinder seat is fixed to the lower surface of the partition plate, the top side of the filter cylinder is detachably connected to the cylinder seat, the filter cylinder is in communication with the space above the partition plate, and four support legs distributed in a rectangular shape are welded to the bottom side of the shell.

[0014] The beneficial effects of adopting the above-mentioned optional scheme are: the interior of the shell is divided into an upper clean air chamber and a lower dust air chamber by a partition. Dust-laden gas enters the dust air chamber through the air hole and passes through the filter cartridge. The dust is intercepted on the outside of the filter cartridge. The purified gas exits the filter cartridge, enters the clean air chamber through the cartridge seat, and finally exits from another air hole.

[0015] Optionally, the drive assembly includes a plug cylinder fixed to the side wall of the connecting seat and a wave seat fixed to the bottom side of the housing. A first piston is reciprocated inside the plug cylinder. A plug rod extending to the outside of the plug cylinder is fixed to one side of the first piston, and a ball bearing that is rotatably connected to the wave seat is mounted on the other end of the plug rod.

[0016] The advantages of adopting the above-mentioned optional solution are: the electric telescopic rod pushes the connecting seat to rise and fall vertically, which in turn drives the plug cylinder fixed on its side wall to rise and fall synchronously. At this time, the ball is constrained by the physical constraint of the wave seat groove and is forced to move horizontally along the groove trajectory. The first piston is driven to reciprocate horizontally in the plug cylinder by the plug rod, thereby driving the transmission component and cleaning the filter cartridge. In addition, the extension and retraction of the electric telescopic rod can increase the cleaning range of the cleaning mechanism and further improve the cleaning effect of the filter cartridge.

[0017] Optionally, the transmission assembly includes a reciprocating shaft fixed to the upper surface of the mounting platform and extending into the interior of the filter cartridge. The reciprocating shaft is hollow and has a second piston and a push rod inside. The top end of the push rod is fixed to the bottom side of the second piston, and a drive plate connected to a connector is fixed to the top side of the second piston. An air supply pipe is installed between the filter cartridge and the reciprocating shaft.

[0018] The advantages of adopting the above-mentioned optional solutions are: the transmission component, through the unique design of hollow shaft integrating double pistons, efficiently converts air pressure energy into axial impact force and radial driving force, becoming the core hub for realizing micro-power dual-mode dust removal. Through the pulse airflow of the plug cylinder, the air is input into the hollow reciprocating shaft cavity via the air supply pipe and pushes the second piston upward at high speed, so that micro-air pressure input can drive high-intensity axial vibration, meeting the dust removal requirements of the filter cartridge.

[0019] Optionally, a limit frame is fixed inside the reciprocating shaft, the bottom end of the push rod passes through the limit frame, and a return spring is installed between the outer surface of the bottom end of the push rod and the limit frame. The limit frame is hollowed out.

[0020] The advantages of adopting the above-mentioned optional scheme are: the reset spring is pre-compressed and installed between the bottom end of the top rod and the limit frame. When the air pressure pushes the second piston to rise, the reset spring is compressed and stores energy. After the air pressure is released, the reset spring releases its elastic force and pulls the top rod downward to force the second piston to reset, ensuring that the second piston returns to its initial position and prepares for the next dust cleaning.

[0021] Optionally, the drive plate has a groove inside, and the groove has a wavy shape.

[0022] The mounting cylinder is open on both sides and one end is connected to the reciprocating shaft. The connecting member includes a connecting rod fixed to one end of the striking rod. The end of the connecting rod away from the striking rod extends into the reciprocating shaft. A roller that is rotatably connected to the slide groove is mounted on the end of the connecting rod. A limiting seat that limits the movement of the connecting rod is fixed inside the mounting cylinder.

[0023] The beneficial effects of adopting the above-mentioned optional solution are: by driving the striking rod through the wave-shaped chute, radial point striking of the inner wall of the filter cartridge can be achieved, which can loosen the deep layer of the filter material or shake off the dust that has not been removed axially.

[0024] Optionally, a buffer pad can be detachably installed at the end of the striking rod away from the connecting rod. An installation groove is provided inside the striking rod, and the nozzle is fixed in the installation groove. One side of the installation groove is connected to the end of the striking rod, and several spray holes are provided inside the buffer pad.

[0025] The advantages of adopting the above-mentioned optional solution are: the nozzle is fixed in the mounting groove inside the striking rod, making full use of the internal space of the striking rod, avoiding the complexity and space occupation caused by external additional pipe layout, making the overall structure more compact. At the same time, the nozzle is built into the mounting groove inside the striking rod and is protected by the striking rod itself, avoiding direct damage to the nozzle from external collisions, friction or harsh environments, thus improving the service life and operational reliability of the nozzle.

[0026] Optionally, the nozzle includes a throat, an expansion tube, and a connecting tube fixed inside the mounting groove. The expansion tube and the connecting tube are respectively fixed to the left and right ends of the throat, and the expansion tube is flared in shape.

[0027] The beneficial effects of adopting the above-mentioned optional scheme are: reuse the kinetic energy of the exhaust gas generated by the movement of the second piston, the second piston compresses the air in the space at the top of the reciprocating shaft, at this time part of the airflow enters the nozzle through the mounting cylinder, the second piston, which enhances the negative pressure suction, and the negative pressure suction captures the dust agitated by mechanical knocking, preventing secondary adsorption.

[0028] Optionally, a suction tube is installed inside the limiting seat, and an air suction hood is provided at one end of the mounting cylinder connected to the reciprocating shaft. The two ends of the suction tube are respectively fixed to the connecting pipe and the air suction hood.

[0029] The advantages of adopting the above-mentioned optional scheme are: by using the negative pressure generated by the movement of the second piston, combined with the throat structure of the nozzle to accelerate the airflow, a strong suction force is formed to immediately remove the dust that has been knocked off, avoiding secondary adsorption, and realizing a dual cleaning mechanism for efficient dust removal.

[0030] Optionally, the top end of the reciprocating shaft is provided with a lubrication assembly for lubricating the second piston. The lubrication assembly includes a plug fixed to the top end of the reciprocating shaft. A third piston extending into the plug is provided inside the top side of the reciprocating shaft. A drain pipe distributed in annularly is fixed inside the reciprocating shaft. An infusion pipe is installed between the drain pipe and the plug.

[0031] The beneficial effects of adopting the above-mentioned optional scheme are as follows: when the second piston moves up and down in the reciprocating shaft, it will squeeze the space at its top. The third piston moves accordingly in the plug, and the lubricating oil stored in the plug is forced into the annular drain pipe through the infusion pipe. The drain pipe slowly and evenly releases the lubricating oil to the contact surface between the inner wall of the reciprocating shaft and the second piston, thereby achieving automatic lubrication.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. This invention uses a wave-shaped groove to drive a striking rod, which achieves radial point-like striking of the inner wall of the filter cartridge. This can loosen the deep layers of the filter material or shake off the dust that has not been removed axially. Then, the negative pressure generated by the movement of the second piston, combined with the throat structure of the nozzle to accelerate the airflow, forms a strong suction force, which immediately removes the dust that has been knocked off, avoiding secondary adsorption. This achieves a dual cleaning mechanism and efficient dust removal.

[0034] 2. In this invention, the components of the entire system work together through ingenious mechanical connections and motion transmission. From the activation of the electric telescopic rod to the compression of air in the plug cylinder, to the movement of the second piston in the reciprocating shaft, and finally to driving the striking rod to strike the filter cartridge and using negative pressure to suck up dust, each link works closely together. It achieves complex cleaning functions by using mechanical motion and air pressure changes. The design is ingenious.

[0035] 3. This invention employs targeted cleaning to reduce the overall impact. By using radial, point-like mechanical tapping, it can clean specific locations on the inner wall of the filter cartridge. Compared to some large-area cleaning methods, it has less impact on the overall structure of the filter cartridge and the surrounding environment. While ensuring the cleaning effect, it reduces other problems that may be caused by the cleaning operation.

[0036] 4. In this invention, when the second piston moves up and down within the reciprocating shaft, it compresses the space at its top. The third piston moves accordingly within the plug. The movement of the third piston is similar to a small pump, which pumps the lubricating oil stored in the plug into the annular drain pipe through the infusion pipe. The drain pipe slowly and evenly releases the lubricating oil onto the contact surface between the inner wall of the reciprocating shaft and the second piston, achieving automatic lubrication. This not only reduces friction and wear and extends the life of core components, but also ensures that the air pressure energy is converted into the piston's impact kinetic energy more efficiently, making the axial pulse vibration stronger and more stable, and avoiding the attenuation of impact force due to increased friction, which would affect the dust removal effect.

Detailed Implementation

[0049] The following is in conjunction with the appendix Figures 1 to 10 This application will be described in further detail.

[0050] This application discloses a micro-powered point-type cartridge pulse dust collector. Please refer to... Figures 1 to 10A micro-powered point-type cartridge pulse dust collector includes a dust collector body 1, which includes a housing 11 and a filter cartridge 14 detachably installed inside the housing 11. The housing 11 is hollow inside. A partition 12 is fixed on the inner wall of the top side of the housing 11, dividing the interior of the housing 11 into two spaces. Two air holes 15 are opened on the side of the housing 11 and are distributed vertically. The air holes 15 on the top side are higher than the partition 12. A cartridge seat 13 is fixed on the lower surface of the partition 12. The top side of the filter cartridge 14 is detachably connected to the cartridge seat 13. The filter cartridge 14 communicates with the space above the partition 12. Four support legs 3 are welded to the bottom side of the housing 11 and are distributed in a rectangular shape. Specifically, the interior of the housing 11 is divided into an upper clean air chamber and a lower dust chamber by a partition 12. Dust-laden gas enters the dust chamber through the air hole 15 and passes through the filter cartridge 14. Dust is intercepted on the outside of the filter cartridge 14. The purified gas exits the filter cartridge 14, enters the clean air chamber through the cartridge seat 13, and finally exits through another air hole 15.

[0051] To drive the cleaning mechanism 4, the bottom of the housing 11 is provided with a cleaning mechanism 4 extending therein for cleaning the filter cartridge 14 and a driving device for driving the cleaning mechanism 4; the driving device includes an electric telescopic rod 2, which can be fixed by a support frame. A connecting seat 21 is installed on the output end of the electric telescopic rod 2, and a mounting platform 22 is fixed on the top side of the connecting seat 21. A driving assembly 23 is provided on the side of the connecting seat 21 and the bottom side of the housing 11; specifically, the driving assembly 23 includes a plug cylinder 231 fixed on the side wall of the connecting seat 21 and a wave seat 235 fixed on the bottom side of the housing 11. A first piston 232 is reciprocated inside the plug cylinder 231. A plug rod 233 extending to the outside of the plug cylinder 231 is fixed on one side of the first piston 232, and a ball bearing 234 that is rotatably connected to the wave seat 235 is rotatably installed on the other end of the plug rod 233. The electric telescopic rod 2 pushes the connecting seat 21 to rise and fall vertically, which in turn drives the plug cylinder 231 fixed on its side wall to rise and fall synchronously. At this time, the ball 234 is restricted by the physical constraint of the groove of the wave seat 235 and is forced to move horizontally along the groove trajectory. The plug rod 233 drives the first piston 232 to move horizontally and reciprocally in the plug cylinder 231, thereby driving the cleaning mechanism 4 and cleaning the filter cartridge 14. In addition, the extension and retraction of the electric telescopic rod 2 can increase the cleaning range of the cleaning mechanism 4 and further improve the cleaning effect of the filter cartridge 14.

[0052] To clean the filter cartridge 14, the cleaning mechanism 4 includes a transmission component 41 disposed on the mounting platform 22 and extending into the filter cartridge 14. The transmission component 41 is used in conjunction with the drive component 23. A striking component 42 for use with the transmission component 41 is disposed on the side of the transmission component 41. The striking component 42 includes a mounting cylinder 421. A striking rod 422 extending outward is reciprocated inside the mounting cylinder 421. A connector connected to the transmission component 41 is disposed at one end of the striking rod 422. A spray pipe 429 for use with the transmission component 41 is installed inside the striking rod 422. A mounting rod 43 extending into the housing 11 is fixed on the top side of the mounting platform 22. A scraper 44 sleeved on the outside of the filter cartridge 14 is fixed on the top end of the mounting rod 43. The scraper 44 is fixed to the mounting platform 22 by the mounting rod 43, extends to the outside of the filter cartridge 14 and fits onto the outside of the filter cartridge 14, maintaining contact or a slight gap with the outer surface of the filter cartridge 14. When the scraper 44 moves, it physically scrapes away the accumulated dust on the outer surface of the filter cartridge 14, forming an "internal and external attack" cleaning with internal knocking and airflow jetting. The number of knocking components 42 can be multiple.

[0053] The transmission assembly 41 includes a reciprocating shaft 411 fixed to the upper surface of the mounting platform 22 and extending into the interior of the filter cartridge 14. The reciprocating shaft 411 is hollow and contains a second piston 413 and a push rod 412. The top end of the push rod 412 is fixed to the bottom side of the second piston 413, and a drive plate 414 connected to a connector is fixed to the top side of the second piston 413. An air supply pipe 236 is installed between the plug cylinder 231 and the reciprocating shaft 411. Specifically, the transmission assembly 41, through its unique design of a hollow shaft integrating two pistons, efficiently converts air pressure energy into axial impact force and radial driving force, becoming the core hub for achieving micro-power dual-mode dust removal. Through the pulsed airflow of the plug cylinder 231, the air supply pipe 236 is used to input into the inner cavity of the hollow reciprocating shaft 411 and push the second piston 413 upward at high speed, so that a low air pressure input can drive high-intensity axial vibration, meeting the dust removal requirements of the filter cartridge 14.

[0054] It should be noted that a limit frame 415 is fixed inside the reciprocating shaft 411, and the bottom end of the push rod 412 passes through the limit frame 415. A return spring 416 is installed between the outer surface of the bottom end of the push rod 412 and the limit frame 415. The limit frame 415 is hollow. The return spring 416 is pre-compressed and installed between the bottom end of the push rod 412 and the limit frame 415. When the air pressure pushes the second piston 413 upward, the return spring 416 is compressed and stores energy. After the air pressure is released, the return spring 416 releases its elastic force and pulls the push rod 412 downward to force the second piston 413 to return to its initial position, ensuring that the second piston 413 returns to its initial position and prepares for the next dust cleaning. The drive plate 414 has a sliding groove 417 inside, and the sliding groove 417 is wavy in shape. The wavy sliding groove 417 drives the striking rod 422 to achieve radial point-like striking of the inner wall of the filter cartridge 14, which can loosen the deep layer of the filter material or shake off the dust that has not been removed axially.

[0055] It should be noted that the mounting cylinder 421 is open on both sides, and one end of it is connected to the reciprocating shaft 411. The connecting parts include a connecting rod 423 fixed to one end of the striking rod 422. The end of the connecting rod 423 away from the striking rod 422 extends into the reciprocating shaft 411, and a roller 424 that is rotatably mounted on the end of the connecting rod 423 and is rollingly connected to the slide groove 417 is mounted on it. A limiting seat 425 that limits the movement of the connecting rod 423 is fixed inside the mounting cylinder 421. A buffer pad 426 is detachably mounted on the end of the striking rod 422 away from the connecting rod 423. An installation groove 4210 is opened inside the striking rod 422, and a nozzle 429 is fixed in the installation groove 4210. One side of the installation groove 4210 is open to the end of the striking rod 422. Several spray holes 4211 are opened inside the buffer pad 426. The nozzle 429 is fixed in the mounting groove 4210 inside the striking rod 422, making full use of the internal space of the striking rod 422 and avoiding the complexity and space occupation caused by external additional piping, making the overall structure more compact. At the same time, the nozzle 429 is built into the mounting groove 4210 inside the striking rod 422 and is protected by the striking rod 422 itself, avoiding direct damage to the nozzle 429 from external collisions, friction or harsh environments, thus improving the service life and operational reliability of the nozzle 429.

[0056] Specifically, the nozzle 429 includes a throat 4291, an expansion tube 4292, and a connecting tube 4293 fixed inside the mounting groove 4210. The expansion tube 4292 and the connecting tube 4293 are respectively fixed to the left and right ends of the throat 4291, and the expansion tube 4292 is flared in shape. Utilizing the kinetic energy of the exhaust gas generated by the movement of the second piston 413, the second piston 413 compresses the air in the top space of the reciprocating shaft 411. At this time, part of the airflow enters the nozzle 429 through the mounting cylinder 421. The second piston 413 enhances the negative pressure suction, which captures the dust agitated by mechanical impact and prevents secondary adsorption. A suction tube 427 is installed inside the limiting seat 425. A suction hood 428 is provided at the end of the mounting cylinder 421 connected to the reciprocating shaft 411. The two ends of the suction tube 427 are respectively fixed to the connecting tube 4293 and the suction hood 428. By utilizing the negative pressure generated by the movement of the second piston 413, combined with the throat 4291 structure of the nozzle 429 to accelerate the airflow, a strong suction force is formed to immediately remove the dust that has been knocked off, avoiding secondary adsorption and achieving a dual cleaning mechanism for efficient dust removal.

[0057] Additionally, the nozzle 429 can be used for suction or blowing. When the nozzle 429 is suctioning material, an intercepting net can be installed on the suction pipe 427, and a vacuuming pipe can be connected to the suction pipe 427. The suction pipe 427 consists of a rigid pipe and a flexible pipe. The nozzle 4211 is directly opened on the buffer pad 426, which is located at the working end of the striking rod 422, i.e., the end that actually contacts the object being struck. This ensures that the gas can act directly and accurately on the striking point or the area immediately adjacent to the striking point, achieving the best effect.

[0058] To improve the driving effect, a lubrication assembly 45 for lubricating the second piston 413 is provided at the top of the reciprocating shaft 411. The lubrication assembly 45 includes a plug 451 fixed to the top of the reciprocating shaft 411, a third piston 452 extending into the plug 451 and disposed inside the top side of the reciprocating shaft 411, and an annularly distributed drain pipe 454 fixed inside the reciprocating shaft 411. An infusion pipe 453 is installed between the drain pipe 454 and the plug 451. When the second piston 413 moves up and down inside the reciprocating shaft 411, it compresses the space at its top. The third piston 452 moves accordingly inside the plug 451, pushing the lubricating oil stored in the plug 451 into the annular drain pipe 454 through the infusion pipe 453. The drain pipe 454 slowly and evenly releases the lubricating oil onto the contact surface between the inner wall of the reciprocating shaft 411 and the second piston 413, achieving automatic lubrication.

[0059] Combined with appendix Figures 1 to 10 The working principle of the above embodiments is as follows:

[0060] The control system starts the electric telescopic rod 2, which pushes the connecting seat 21 and the mounting platform 22 upward. The plug cylinder 231 fixed on the side of the connecting seat 21 moves upward accordingly. At this time, the ball 234 at the end of the plug rod 233 rolls in the groove of the wave seat 235 fixed to the bottom of the housing 11. The wave-shaped groove forces the ball 234 to drive the plug rod 233 and the first piston 232 to make horizontal reciprocating motion in the plug cylinder 231. The movement of the first piston 232 compresses the air in the plug cylinder 231. The compressed air in the plug cylinder 231 enters the cavity of the reciprocating shaft 411 through the air supply pipe 236.

[0061] Air pressure drives the second piston 413 inside the reciprocating shaft 411 to move upward. The second piston 413 drives the drive plate 414 fixed on its top to move upward together. When the drive plate 414 moves upward, the wave-shaped groove 417 inside it also moves. The roller 424 installed at the end of the connecting rod 423 is embedded in the groove 417. The wave shape of the groove 417 forces the roller 424 to produce a horizontal displacement in the groove 417. The horizontal displacement of the roller 424 drives the striking rod 422 to move horizontally reciprocally in the mounting cylinder 421 through the connecting rod 423. At this time, when the striking rod 422 moves outward, the buffer pad 426 at its end strikes the inner wall of the filter cylinder 14, thereby realizing radial, point-type mechanical knocking to loosen the dust deep in the filter material or the dust that could not be completely removed by axial shaking.

[0062] When the second piston 413 moves rapidly upward under air pressure, a momentary negative pressure is generated at the top of the reciprocating shaft 411. One end of the suction pipe 427 is connected to the suction hood 428, and the other end is connected to the connecting pipe 4293 of the nozzle 429. At this time, if there is airflow passing through the throat 4291 of the nozzle 429, the airflow is accelerated at the throat 4291 by utilizing the Venturi effect, and the pressure decreases, generating a stronger negative pressure at the connecting pipe 4293. This negative pressure, through the suction pipe 427 and the suction hood 428, sucks away some of the dust that was shaken off during the impact and is close to the inner wall of the filter cartridge 14, and sprays it out through the nozzle 429 or guides it to a specific area such as the ash hopper to prevent secondary adsorption and improve the cleaning effect of the filter cartridge 14.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
