Description

Technical Field

[0001] The present invention belongs to the technical field of industrial dust removal, and particularly relates to a novel self-cleaning filter element and a dust collector thereof. Background Art

[0002] A dust collector is a device used to remove particulate pollutants from gases. It is widely used in industrial production, commercial environments, and household air purification to improve air quality, protect equipment and personnel health. According to its working principle and technical characteristics, dust collectors can be divided into various types, such as bag dust collectors, electrostatic precipitators, cyclone dust collectors, etc. The filter element is one of the core components of the dust collector, and it is directly responsible for the filtration process, that is, separating particulate matter from the air flow. The design and material selection of the filter element directly affect the overall performance and efficiency of the dust collector. The filter element captures particulate matter in the air through physical interception, inertial collision, diffusion effect, etc. Conventional filter elements mostly adopt the form of corrugated filter layers and enclosing nets, and then connect components such as the filter layer and end caps of the filter element together through processing means such as gluing and welding to achieve the overall strength, dirt holding capacity, and other filtration effects of the filter element. Due to its advantages such as simple structure, easy production, and convenient installation, it is widely used in dust collector components. Often due to the influence of the installation space inside the dust collector and the installation form of the filter element, the dirt holding capacity and permeability of the filter element are limited within the effective installation space, thus failing to achieve the ideal filtration effect.

[0003] The existing Chinese patent document with the publication number CN111437642B proposes a high-throughput and high-dirt-holding filter element. By designing a sealing ring assembly with upper and lower sealing buckles and a permeable outer sheath, and arranging a filter layer assembly inside the outer sheath, the filter layer assembly is composed of a bottom filter layer and a disc-shaped filter layer with a central hole sequentially stacked on the bottom filter layer to solve the above technical problems. However, due to the design of the disc-shaped filter layer, multiple filter layers are generated, which will cause dust and other particulate matter to accumulate more easily around the holes or in the gaps between the filter layers. It is often very difficult to completely remove pollutants in these places, and over time, it will affect the subsequent filtration ability of the filter element.

[0004] Therefore, the present invention proposes a novel self-cleaning filter element and a dust collector thereof to solve the problem that it is difficult to clean dust in the stacked filter element in the prior art. By improving the structure of the filter element, designing a multi-layer deformable filter core tube, increasing the dirt-holding and filtration ability of the filter element, and combining the mutual knocking and collision of multiple filter mesh sheets after deformation with pulsed air flow flushing, the purpose of self-cleaning the filter element is effectively achieved, so that dust can be effectively removed.

Specific implementation mode

[0035] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] Embodiment 1

[0037] Please refer to Figures 1 to 16, the present invention provides a technical solution: a novel self-cleaning filter element, which includes a central connecting pipe 1. Below the central connecting pipe 1, there is a central ventilation pipe assembly 4. The central ventilation pipe assembly 4 includes a ventilation pipe 41. The upper end of the ventilation pipe 41 is fixedly connected to the lower end of the central connecting pipe 1. An active filter pipe assembly 2 is arranged outside the central ventilation pipe assembly 4. The active filter pipe assembly 2 includes an active pipe 21. A second air groove 42 is formed in the side wall of the ventilation pipe 41. On both sides of the second air groove 42, there are respectively an active air guiding plate 43 and a fixed air guiding plate 432. The active air guiding plate 43 is rotatably installed in the middle of the side wall of the ventilation pipe 41. A return gasket 431 is fixedly installed between the side surface of the active air guiding plate 43 and the inner surface of the ventilation pipe 41. Above the inner surface of the active pipe 21, a sealing ring 211 is fixedly installed. The active pipe 21 is rotatably installed on the outer surface of the ventilation pipe 41 through the sealing ring 211. The fixed air guiding plate 432 is fixedly installed on the outer surface of the ventilation pipe 41. The side surface of the fixed air guiding plate 432 is in contact with the inner surface of the active pipe 21. On the outer side surface of the active pipe 21, side flow guide pipes 25 are evenly distributed. The side flow guide pipes 25 and the side wall of the active pipe 21 are both provided with a first air groove 212 adapted to the second air groove 42. The side surface of the active air guiding plate 43 is in contact with the side wall of the first air groove 212;

[0038] In this embodiment, the central connecting pipe 1 is mainly used for installing and connecting with the internal components of the dust collector main body 5. The ventilation pipe 41 is mainly used for the upward output and discharge of clean air and the downward delivery of pulsed air flow to backwash the active filter pipe assembly 2 and the fixed filter pipe assembly 3. The clean air and the pulsed air flow mainly enter or are evenly dispersed and output through the second air groove 42. The difference is that when cooperating with the active pipe 21, in the filtering state, the positions of the second air groove 42 and the first air groove 212 coincide. At this time, the active air guiding plate 43 and the fixed air guiding plate 432 cooperate to maintain the maximum opening and closing state, so that the air flow rate remains the largest. When the pulsed air flow is used for backwashing, at this time, the outer gear ring 22 will rotate a certain angle, and the maximum rotation angle is set to 45°. In this state, the positions of the second air groove 42 and the first air groove 212 are staggered. The active air guiding plate 43 is driven by the position movement of the first air groove 212 to deflect, and the opening and closing angle with the fixed air guiding plate 432 becomes smaller. At this time, the flow rate of the air flow will increase because the channel becomes narrower when passing through, making the backwashing force greater and the washing cleaner. At the same time, after the active air guiding plate 43 deflects, it also has a guiding effect on the air flow, so that the air flow is directly washed against the filter mesh surfaces of the first filter core plate 24 and the second filter core plate 33 after being guided by the active air guiding plate 43, further improving the backwashing effect of the filter mesh surfaces of the first filter core plate 24 and the second filter core plate 33. After the backwashing is completed, the active pipe 21 rotates and resets, so that the positions of the first air groove 212 and the second air groove 42 coincide and reset again. At this time, the active air guiding plate 43 also resets under the rebound action of the return gasket 431, still maintaining the maximum opening and closing degree with the fixed air guiding plate 432, so that the air flow rate returns to the largest.

[0039] Embodiment 2

[0040] Please refer to Figures 1 to 16 , on the basis of Embodiment 1, in order to increase the filtration area of the filter element, this embodiment further proposes that a first filter core plate 24 is arranged on the outer side of the movable pipe 21. An external gear ring 22 and an upper closing cover plate 23 are fixedly installed above the outer surface of the movable pipe 21. The lower surface of the upper closing cover plate 23 is fixedly connected to the upper surfaces of the first filter core plate 24 and the side diversion pipe 25. The first filter core plate 24 is arranged outside the side diversion pipe 25. A first closing blocking frame 241 is fixedly installed on one side of the inner surface of the first filter core plate 24. A first auxiliary filter core plate 242 is rotatably installed on the other side of the inner surface of the first filter core plate 24. A first movable connecting rod 243 is movably installed between the side surface of the first auxiliary filter core plate 242 and the inner surface of the first filter core plate 24. A fixed filter core pipe assembly 3 is arranged outside the central ventilation pipe assembly 4. The fixed filter core pipe assembly 3 includes a lower closing cover plate 31 fixedly installed on the outer side of the bottom of the ventilation pipe 41. A limiting frame 32 and a second filter core plate 33 are arranged above the lower closing cover plate 31. Ash discharge grooves 311 are staggeredly formed on the surface of the lower closing cover plate 31. The second filter core plate 33 is fixedly installed on the upper surface of the lower closing cover plate 31. The position of the lower closing cover plate 31 is staggeredly distributed with the position of the first filter core plate 24. The second filter core plate 33 is arranged inside the ash discharge grooves 311. A second closing blocking frame 331 is fixedly installed on one side of the outer surface of the second filter core plate 33 close to the first auxiliary filter core plate 242. A second auxiliary filter core plate 332 is rotatably installed on the other side of the outer surface of the second filter core plate 33. A second movable connecting rod 333 is movably installed between the inner side surface of the second auxiliary filter core plate 332 and the outer surface of the second filter core plate 33;

[0041] In this embodiment, the filter core plate 1 24 and the filter core plate 2 33 are arranged alternately, the filter core plate 1 24 is connected to the auxiliary filter core plate 1 242 through the movable connecting rod 1 243, and the filter core plate 2 33 is connected to the auxiliary filter core plate 2 332 through the movable connecting rod 2 333, and the sides between the filter core plate 1 24 and the filter core plate 2 33 are closed respectively, and the filter material is laid and installed on the surfaces of the filter core plate 1 24, the filter core plate 2 33, the auxiliary filter core plate 1 242, and the auxiliary filter core plate 2 332. For example, filter paper, filter bag or filter screen forms a complete filter element assembly, and the closed baffle frame 231 and the closed baffle frame 1 241 mainly play a role of blocking the auxiliary filter core plate 1 242 and the auxiliary filter core plate 2 332 that are in contact with each other. This design makes the filter element in a normal filtering state. The filter core plate 233, the filter core plate 1 24 and the auxiliary filter core plate 2 332 and the auxiliary filter core plate 1 242 respectively set on the side form a staggered filtering space, which increases the pollution filtration capacity of the filter element. The movable pipe 21 The upper closed cover plate 23 not only seals the top of the filter core plate 1 24 and the filter core plate 2 33, but also connects the filter core plate 1 24 and the side guide pipe 25. In this way, when the movable pipe 21 rotates 45° for backwashing, the filter core plate 2 33 and the filter core plate 1 24 are staggered. At this time, the closed baffle frame 2 331 and the closed baffle frame 1 241 cancel the contact and blocking effect of the auxiliary filter core plate 1 242 and the auxiliary filter core plate 2 332 that are in contact with them. The auxiliary filter core plate 2 332 and the auxiliary filter core plate 1 242 will be respectively moved and expanded under the cooperation of the movable connecting rod 2 333 and the movable connecting rod 1 243, and a shake will occur to make the attached dust easier to fall. With the help of pulse airflow flushing and multiple repeated activities, dust can be effectively removed to achieve the purpose of complete self-cleaning of the filter element. The lower closed cover plate 31 mainly fixes the filter core plate 2 33 and connects with the ventilation pipe 41. The purpose of opening the dust discharge groove 311 is to make the dust on the surface of the inner filter core plate 2 33 easy to be discharged from the bottom after it falls.

[0042] Embodiment 3

[0043] See also Figures 1 to 16 On the basis of the second embodiment, in order to increase the self-cleaning effect of the filter element, the present embodiment further proposes that the limit frame 32 is rotatably mounted on the upper surface of the lower closed cover plate 31, the limit frame 32 is arranged on the outer side of the second filter core plate 33, and a reset connecting frame 322 is fixedly mounted on the inner surface of the limit frame 32 near one end of the rotating shaft, one end of the reset connecting frame 322 is fixedly connected to the side surface of the second closed blocking frame 331, and a limited position blocking piece 321 is fixedly mounted on the inner surface of the other end of the limit frame 32, and a dust removal scraper 323 is arranged on one side of the reset connecting frame 322, and the dust removal scraper 323 is rotatably mounted on the side wall of the limit frame 32, and one end of the scraper of the dust removal scraper 323 contacts the outer surface of the second filter core plate 33;

[0044] In this embodiment, in addition to limiting the rotation of the first filter core plate 24, the limiting frame 32 also plays an auxiliary cleaning role on the surface of the second filter core plate 33. Specifically, when the filter element performs backwashing self-cleaning, the first filter core plate 24 rotates 45° along with the movable pipe 21. At this time, the first filter core plate 24 will push the limiting resistance piece 321, causing the limiting frame 32 to turn outward by a certain angle. At this time, the dust removal scraper 323 will slide along the outer surface of the second filter core plate 33 due to the extrusion on the other side of the limiting frame 32, playing a certain auxiliary cleaning role on the outer surface of the second filter core plate 33. And convex ribs can be provided on the side surface of the limiting resistance piece 321, so that as the first filter core plate 24 rotates and advances, it can contact the convex ribs and cause it to vibrate slightly, making it easier to shake off the dust. After the backwashing is completed, the first filter core plate 24 rotates and resets along with the movable pipe 21. At this time, the limiting frame 32 is reset under the cooperation of the reset connecting frame 322.

[0045] Embodiment 4

[0046] Please refer to Figures 1 to 16 , on the basis of Embodiment 3, this embodiment also proposes a dust collector for installing the above-mentioned novel self-cleaning filter element, including a dust collector main body 5. An air outlet pipe 51 is fixedly installed at the top of the dust collector main body 5, an air inlet pipe 52 is fixedly installed on the side wall of the dust collector main body 5, an industrial dust removal fan 53 is fixedly installed on one side of the inner surface of the dust collector main body 5, a pulse backblowing dust removal assembly 54 is fixedly installed on the other side of the inner surface of the dust collector main body 5, an installation partition plate 55 is fixedly installed in the middle of the inner surface of the dust collector main body 5, a connecting main pipe 56 is arranged above the installation partition plate 55, the side wall of the connecting main pipe 56 is fixedly connected to the air suction pipe end of the industrial dust removal fan 53, a connecting main pipe 56 adapted to the central connecting pipe 1 is fixedly installed below the connecting main pipe 56, and a driving assembly 551 is fixedly installed in the middle of the upper surface of the installation partition plate 55;

[0047] In this embodiment, a power supply and control equipment are arranged on the outer side of the dust collector main body 5. The installation partition plate 55 divides the interior of the dust collector main body 5 into two spaces. The upper space is used to install components such as the industrial dust removal fan 53 and the pulse backwashing dust removal assembly 54, and the lower space is used to install a filter element as an air filtration chamber. The central connecting pipe 1 can integrally install the filter element by connecting with the sealing sleeve 561. The specific connection method can be threaded connection or bolt connection. It should be noted that the sealing sleeve 561 is mainly wrapped on the outer surface of the central connecting pipe 1 and does not affect the movable pipe 21. The external gear ring 22 needs to be fixed on the outside of the movable pipe 21 by bolts. After the preliminary installation of the filter element is completed and it is ensured to be in a normal filtering state, then adjust the position of the external gear ring 22 so that it is in normal meshing with the gear of the driving assembly 551 and then fix the external gear ring 22. At this time, the installation of the filter element is completed. The driving assembly 551 mainly includes a motor fixedly installed on the upper surface of the installation partition plate 55 and a gear installed on the output shaft of the motor. The pulse backwashing dust removal assembly 54 mainly consists of a compressed air package, an electromagnetic pulse valve, and a backwashing pipe. Among them, four groups of backwashing pipes are arranged to penetrate and connect the inner wall of the top of the main pipe 56 and extend into the lower part of the sealing sleeve 561, which is convenient for conveying backwashing air flow to the ventilation pipe 41. When the dust collector main body 5 is working normally, the air with dust enters the air filtration chamber below the interior of the dust collector main body 5 through the air inlet pipe 52. At this time, the industrial dust removal fan 53 works to suck air through the main connecting pipe 56. The air is filtered by the filter element plate two 33, the filter element plate one 24 and the auxiliary filter element plate two 332 and the auxiliary filter element plate one 242 respectively arranged on the side. After the dust is filtered off, the clean air enters the ventilation pipe 41 through the air slot two 42 and is discharged through the air outlet pipe 51 under the action of the industrial dust removal fan 53. In the backwashing mode, the motor of the driving assembly 551 drives the external gear ring 22 to rotate through the gear, so that the movable pipe 21 and its external components are staggered from the ventilation pipe 41 and its external components. At this time, the electromagnetic pulse valve of the pulse backwashing dust removal assembly 54 is opened, and the air flow of the compressed air package enters the ventilation pipe 41 through the backwashing pipe to perform backwashing on the filter element plate two 33, the filter element plate one 24, the auxiliary filter element plate two 332 and the auxiliary filter element plate one 242. After the backwashing is completed, the motor of the driving assembly 551 drives the external gear ring 22 to rotate in the reverse direction through the gear, so that the movable pipe 21 and its external components are reset with the ventilation pipe 41 and its external components, and the filtration continues.

[0048] Embodiment Five

[0049] Please refer to Figures 1 to 16 , on the basis of Embodiment Four, this embodiment also proposes a use method of a new self-cleaning filter element and its dust collector, including the following steps:

[0050] Step 1: Install the filter element. Open the closed door in front of the main body 5 of the dust collector, pass the central connecting pipe 1 through the installation partition 55 and connect it to the sealing sleeve 561 to initially complete the installation of the filter element. It should be noted that at this time, the filter element plate one 24 and the filter element plate two 33 are in the correct position and in the normal filtering state. Then, adjust the position of the outer gear ring 22 so that it is in normal meshing with the gear of the driving component 551, and then fix the outer gear ring 22 outside the movable pipe 21 to complete the installation of the filter element.

[0051] Step 2: Conduct normal filtration. The air with dust enters the air filtration chamber below the interior of the main body 5 of the dust collector through the air inlet pipe 52. At this time, the industrial dust removal fan 53 operates to suck air through the connecting main pipe 56. The air passes through the staggered filtration spaces formed by the filter element plate two 33, the filter element plate one 24 and the auxiliary filter element plate two 332 and the auxiliary filter element plate one 242 respectively arranged on the side to filter out the dust. Then, the clean air sequentially passes through the wind grooves one 212 and the wind grooves two 42 with overlapping positions and enters the ventilation pipe 41, and is conveyed upward under the action of the industrial dust removal fan 53, passes through the sealing sleeve 561 and the air outlet pipe 51 in sequence, and finally is discharged through the air outlet pipe 51.

[0052] Step 3: During backwashing, the motor of the driving component 551 drives the outer gear ring 22 to rotate through the gear, causing the movable pipe 21 to rotate. The filter element plate two 33 and the filter element plate one 24 are staggered. At this time, the closing brackets two 331 and the closing brackets one 241 both cancel the contact blocking effect on the auxiliary filter element plate one 242 and the auxiliary filter element plate two 332 in contact with them. The auxiliary filter element plate two 332 and the auxiliary filter element plate one 242 will respectively move and unfold with the cooperation of the movable connecting rod two 333 and the movable connecting rod one 243, causing a jolt once, making the attached dust more likely to fall. At this time, the electromagnetic pulse valve of the pulse backwashing dust removal component 54 is opened, so that the compressed air in the air bag flows through the backwashing pipe and enters the ventilation pipe 41. Because the positions of the wind grooves two 42 and the wind grooves one 212 are staggered, the movable air guiding plate 43 is driven by the position movement of the wind grooves one 212 to deflect, and the opening and closing angle with the fixed air guiding plate 432 becomes smaller. At this time, the flow rate of the air will increase because the channel becomes narrower when passing through. At the same time, after the movable air guiding plate 43 deflects, it also has a guiding effect on the air flow, so that the air flow is guided by the movable air guiding plate 43 and directly flushes the filter net surfaces of the filter element plate two 33, the filter element plate one 24, the auxiliary filter element plate two 332 and the auxiliary filter element plate one 242. Along with the backwashing process, the motor of the installation partition 55 drives the movable pipe 21 to rotate back and forth within a certain angle through the gear, cooperating with the pulsed air flow flushing and multiple repeated movement processes, which can effectively remove the dust and achieve the purpose of complete self-cleaning of the filter element. Finally, after the backwashing is completed, the motor of the driving component 551 drives the outer gear ring 22 to rotate in the reverse direction, causing the movable pipe 21 and its external components and the ventilation pipe 41 and its external components to completely return to their positions, and the main body 5 of the dust collector returns to the filtering state.
