Description

Technical Field

[0001] The invention relates to a high-efficiency dust-cleaning filter cartridge mechanism, in particular to a bottom pneumatically assisted vibration high-efficiency dust-cleaning filter cartridge mechanism, belonging to the technical field of filter cartridges. Background Art

[0002] The filter cartridge is a surface filter element that uses the tiny air-permeable structure formed on the surface of the filter material to block particulate matter in the gas. When the dust-laden gas enters the filter cartridge, the dust particles are blocked on the surface of the filter cartridge because the pore size is much smaller than their own size, while the clean gas passes through the filter cartridge into the clean air chamber and is discharged. In the process of cleaning the filter cartridge, high-pressure gas pulse backflushing is usually used for cleaning. The parameters pre-set by the controller are used to give the solenoid valve a signal, which instantly opens and closes the solenoid valve diaphragm, allowing high-pressure gas to enter the blowpipe, and the rapid expansion force of the gas is used to shake off the dust on the surface of the filter cartridge. In addition, for small single-unit filter cartridge dust collectors, the shaking force generated by the eccentric device on the dust collector plate can also be used for cleaning.

[0003] Similar to the above application, there are still some deficiencies:

[0004] The mechanical vibration method requires shutdown for operation, which is inconvenient to use. When using high-pressure gas pulse backblowing, the shape and position of the filter material are fixed, and the surface of the filter material has many folds. The gaps between the folds are not the same, and it cannot be guaranteed that each fold can be cleaned evenly and effectively. Some filter cartridges may be over-cleaned, while others may be under-cleaned, affecting the overall filtering effect.

[0005] Therefore, a bottom pneumatic assisted vibration high-efficiency filter cartridge cleaning mechanism is designed to optimize the above problems. Summary of the Invention

[0042] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0043] like Figures 1-8 As shown, this embodiment provides a bottom pneumatically assisted vibration high-efficiency dust cleaning filter cartridge mechanism, comprising a bottom cover 1, a mesh cylinder 2 fixed on the top of the bottom cover 1, a top cover 3 fixed on the top of the mesh cylinder 2, and a filter material 4 sleeved on the outside of the mesh cylinder 2, the filter material 4 is provided with a reset mechanism 5 movably connected with the bottom cover 1 and the top cover 3, the outside of the filter material 4 is evenly provided with an outer protective mechanism 6 that fits the surface of the filter material 4, the inside of the bottom cover 1 is provided with an expansion mechanism 7 for controlling the outward movement of the outer protective mechanism 6, the bottom end of the bottom cover 1 is provided with a protective shell 8, the inner bottom of the protective shell 8 is installed with a pneumatic vibrator 9, a mounting plate 10 is horizontally arranged on the top of the top cover 3, an elastic connecting member 11 is provided between the mounting plate 10 and the top cover 3, and a mounting mechanism 12 is provided on the outside of the bottom of the mounting plate 10.

[0044] The overall working principle is: during installation, the device is vertically inserted into the fixing hole above the flower plate, and then the position of the mounting plate 10 is fixed by the mounting mechanism 12. After installation, due to the presence of the elastic connecting member 11, the top cover 3 and the mounting plate 10 are in a movably connected state, and the outer protection mechanism 6 is tightly attached to the outer surface of the filter material 4 and limits the surface of the filter material 4. The inner side of the filter material 4 is attached to the surface of the mesh tube 2 due to the presence of the reset mechanism 5, and the two ends of the filter material 4 are respectively in a movably connected state with the bottom cover 1 and the top cover 3. When the filter tube is dusted, the restriction on the outside of the filter material 4 is released by the expansion mechanism 7 so that the filter material 4 can expand outward. At the same time, high-pressure gas enters the blowpipe, and the rapid expansion force of the gas is used to expand the filter material 4 outward, and the surface of the filter material 4 is evenly blown, and then reset by the reset mechanism 5. During the high-pressure gas pulse backblowing process, the pneumatic vibrator 9 is continuously turned on to control the filter material 4 to shake up and down, which can speed up the removal of dust.

[0045] In this embodiment, the reset mechanism 5 includes a rubber elastic membrane 501, an annular elastic band 502 and an annular corrugated steel band 503. The rubber elastic membrane 501 is fixed to the top and bottom ends of the filter material 4, and the inner ring of the rubber elastic membrane 501 is fixedly connected to the outer edges of the bottom cover 1 and the top cover 3. The annular elastic band 502 is horizontally fixed to the tip of the inner fold of the filter material 4, and the inner side of the annular elastic band 502 is in contact with the outer side of the mesh tube 2. The annular corrugated steel band 503 is in contact with the inner surface of the filter material 4, and the annular corrugated steel band 503 has the same shape as the filter material 4 in top view.

[0046] Local working principle: The filter material 4 is connected to the outer edges of the bottom cover 1 and the top cover 3 through the rubber elastic membrane 501. When the filter material 4 is expanded due to high-pressure inflation, the rubber elastic membrane 501, the annular elastic band 502 and the annular corrugated steel belt 503 are all deformed under the action of air pressure. The existence of the rubber elastic membrane 501 can not only ensure that the end of the filter material 4 is in a movable connection state, but also ensure the sealing of the end of the filter material 4 during the expansion process. After expansion, the filter material 4 can be quickly reset by utilizing the elastic force of the rubber elastic membrane 501, the annular elastic band 502 and the annular corrugated steel belt 503. By repeatedly controlling the expansion and contraction of the filter material 4, the filter material 4 is forced to vibrate, thereby accelerating the cleaning rate.

[0047] In this embodiment, the outer protection mechanism 6 includes a lower guard plate 601, an upper guard plate 602, a vertical rod 603 and a curved rod 604. The lower guard plate 601 is evenly fitted on the outer side of the bottom cover 1, and the ends of the lower guard plate 601 are fitted together. The upper guard plate 602 is evenly fitted on the outer side of the top cover 3, and the ends of the upper guard plate 602 are fitted together. The number of lower guard plates 601 and upper guard plates 602 is the same. Vertical rods 603 are vertically fixed between the lower guard plate 601 and the upper guard plate 602. Curved rods 604 are evenly provided on the vertical rods 603, and the ends of the curved rods 604 on adjacent vertical rods 603 are fitted together.

[0048] Local working principle: Under normal filtering conditions, multiple groups of lower guard plates 601 and upper guard plates 602 are all arranged in a circle to limit the ends of the filter material 4. At the same time, the middle position of the filter material 4 is limited and protected by the vertical rod 603 and the arc rod 604. When the limiting state of the filter material 4 is released, the multiple groups of lower guard plates 601 and upper guard plates 602 are opened to each other.

[0049] In this embodiment, the outer side of the top cover 3 is evenly provided with sliding grooves 605 along the circumferential direction, and the interior of the sliding grooves 605 is slidably installed with sliding rods 606. The ends of the sliding rods 606 are fixedly connected to the inner side of the upper guard plate 602, and a first spring 607 is provided between the ends of the sliding rods 606 and the ends of the sliding grooves 605.

[0050] Partial working principle: When the upper guard plate 602 moves outward, it will drive the slide rod 606 to slide and stretch the first spring 607. The first spring 607 can accelerate the reset rate of the upper guard plate 602 when the upper guard plate 602 is reset.

[0051] In this embodiment, the expansion mechanism 7 includes an installation cavity 701, a turntable 702, an arcuate groove 703, a slider 704, a push rod 705 and a sliding hole 706. The installation cavity 701 is opened inside the bottom cover 1, and the turntable 702 is rotatably installed on the inner bottom of the installation cavity 701. The turntable 702 is evenly provided with arcuate grooves 703 in a ring array, and the insides of the arcuate grooves 703 are all slidably installed. The outer side of the installation cavity 701 is evenly provided with sliding holes 706 along the circumferential direction, and the insides of the sliding holes 706 are all slidably installed with push rods 705. The end of the push rod 705 located outside the bottom cover 1 is fixedly connected to the lower guard plate 601, and the end of the push rod 705 away from the lower guard plate 601 is fixedly connected to the slider 704. A rotating component for controlling the rotation of the turntable 702 is provided inside the protective shell 8.

[0052] Local working principle: When the limiting state of the filter material 4 is released, the rotation of the turntable 702 is controlled by the rotating assembly. Since the push rod 705 passes through the sliding hole 706, the sliding hole 706 has a certain limiting effect on the push rod 705, so the push rod 705 can only slide along the length direction of the sliding hole 706. When the turntable 702 rotates, the slider 704 at the bottom of the push rod 705 will slide simultaneously inside the arc groove 703, thereby controlling multiple groups of push rods 705 to extend outward at the same time, and then unfolding multiple groups of lower guard plates 601.

[0053] In this embodiment, the slider 704 is cylindrical in shape, the outer arc surface of the slider 704 fits in contact with the inner side of the arc groove 703 , and the inner side of the slider 704 is coated with a wear-resistant coating.

[0054] Partial working principle: The cylindrical slider 704 can reduce the friction between the slider 704 and the inner side of the arc groove 703, thereby reducing the wear of the slider 704 during use.

[0055] In this embodiment, the rotating assembly includes an air cylinder 707, an air pipe 708, a piston 709, a second spring 7010, a rack 7011, a connecting rod 7012 and a gear 7013. The air cylinder 707 is horizontally fixed to the bottom of the bottom cover 1. The air pipe 708 is fixed to the end of the air cylinder 707, and the air pipe 708 extends to the bottom of the protective shell 8. The protective shell 8 is provided with an air hole that is connected to the interior of the air cylinder 707. The piston 709 is slidably installed at the middle position inside the air cylinder 707. The second spring 7010 is installed between the piston 709 and the inner end of the air cylinder 707. The rack 7011 is installed on the side of the piston 709 away from the second spring 7010. The connecting rod 7012 is rotatably installed at the middle position of the bottom cover 1. The bottom end of the connecting rod 7012 extends to the interior of the air cylinder 707, and the bottom end of the connecting rod 7012 is fixed to the gear 7013 that meshes with the rack 7011.

[0056] Local working principle: During installation, connect the air pipe 708 with the pipeline of the high-pressure gas pulse backblowing system. When performing high-pressure gas pulse backblowing, the gas will not only enter the interior of the filter cartridge, but also enter the air cylinder 707, pushing the piston 709 to squeeze the second spring 7010. When the piston 709 moves, it will control the rotation of the gear 7013. The gear 7013 drives the rotation of the turntable 702 through the connecting rod 7012. The rotation of the turntable 702 will unfold the guard plate and release the external restriction of the filter material 4. When the exhaust is completed, the second spring 7010 controls the piston 709 to reset under the action of tension, and the turntable 702 rotates in the opposite direction, while controlling the reset of the guard plate.

[0057] In this embodiment, the elastic connecting member 11 includes a third spring 1101, a damper 1102 and a rubber membrane 1103. The third spring 1101 is evenly fixed between the top of the top cover 3 and the mounting plate 10. The damper 1102 is provided inside the third spring 1101, and the ends of the damper 1102 are respectively connected to the top cover 3 and the mounting plate 10. A rubber membrane 1103 is provided between the top cover 3 and the mounting plate 10. There are two groups of rubber membranes 1103, and the third spring 1101 is located between the two groups of rubber membranes 1103.

[0058] Partial working principle: The top cover 3 and the mounting plate 10 are movably connected via a third spring 1101. When the pneumatic vibrator 9 is activated, the filter material 4 is driven to vibrate up and down. During the vibration process, the rubber membrane 1103 ensures the sealing of the device.

[0059] In this embodiment, the mounting mechanism 12 includes a mounting hole 1201, a fourth spring 1202 and a fixing ring 1203. The mounting holes 1201 are evenly arranged on the outside of the mounting plate 10. The cross-sectional shape of the mounting hole 1201 is convex. The fourth spring 1202 is installed at the inner top of the mounting hole 1201, and the fixing ring 1203 is installed at the bottom end of the fourth spring 1202. The outer diameter of the fixing ring 1203 is smaller than the outer diameter of the bottom end of the mounting hole 1201.

[0060] Partial working principle: When the filter material 4 is vertically inserted from the fixing hole on the flower plate, the fourth spring 1202 can be used to reduce the impact force on the device, and then the bolt is used to pass through the installation hole 1201 and the hole on the flower plate, and is tightened and fixed with the nut. After fixation, the fourth spring 1202 is in a fixed state. When the device is disassembled, the fourth spring 1202 is reset and lifted up, and the device can be quickly lifted out.

[0061] In this embodiment, a sealing ring 1001 is fixed to the bottom of the mounting plate 10 , and the mounting holes 1201 are all located outside the sealing ring 1001 .

[0062] Local working principle: after the installation of the plate 10, the sealing ring 1001 is tightly attached to the flower plate, ensuring the stability of the connection between the device and the flower plate.
