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. It uses the tiny air-permeable tissue 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 due to their pore size being 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 backblowing is usually used for cleaning. The solenoid valve is given a signal using the parameters pre-set by the controller, 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 shortcomings: 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, the filter material surface has many folds, and the gaps between the folds are not the same. 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.

[0004] Therefore, a bottom pneumatic-assisted vibration high-efficiency filter cartridge cleaning mechanism is designed to optimize the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide a bottom pneumatically assisted vibration high-efficiency dust cleaning filter cartridge mechanism, through the filter material is provided with a reset mechanism composed of a rubber elastic film, an annular elastic belt, and an annular corrugated steel belt, and the rubber elastic film is respectively arranged at the top end and the bottom end of the filter material and respectively connected to the bottom cover and the top cover, so that the filter material and the bottom cover and the top cover are in an active connection state, and then the expansion mechanism on the outside of the filter material is used to position the filter material, so that when the high-pressure gas pulse backblowing is performed, the positioning state of the filter material is released, the outward expansion and expansion of the filter material can be controlled, the spacing between the folds on the inner side of the filter material is increased, the contact effect between the gas and the filter material is improved, and the filter material can be cleaned evenly and effectively. By installing a pneumatic vibrator at the inner bottom of the protective shell, the filter material can be controlled to vibrate up and down during the pulse backblowing process. In addition, when the filter material expands outward during backblowing and contracts using the reset mechanism, the continuous expansion and contraction causes forced vibration, which improves the cleaning effect and rate during use.

[0019] 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 further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0020] like Figure 1-Figure 8 As shown, the present 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.

[0021] The overall working principle is as follows: during installation, the device is vertically inserted from the fixing hole above the flower plate, and then the mounting mechanism 12 is used to fix the position of the mounting plate 10. After installation, due to the presence of the elastic connector 11, the top cover 3 and the mounting plate 10 are in a state of active connection, the outer protection mechanism 6 is tightly attached to the outer surface of the filter material 4, and the surface of the filter material 4 is limited and protected, and 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 state of active connection 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, and at the same time, high-pressure gas enters the blowing pipe, 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, and 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 cleaning of dust.

[0022] 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 at the top and bottom ends of the filter material 4, and the inner circle of the rubber elastic membrane 501 is fixedly connected to the outer sides of the bottom cover 1 and the top cover 3. The annular elastic band 502 is horizontally fixed to the tip of the inner folds 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.

[0023] Local working principle: the filter material 4 is connected to the outer sides of the bottom cover 1 and the top cover 3 through the rubber elastic membrane 501. When the filter material 4 is inflated due to high-pressure inflation, the rubber elastic membrane 501, the annular elastic belt 502 and the annular corrugated steel belt 503 are 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 belt 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.

[0024] In this embodiment, the outer guard mechanism 6 includes a lower guard plate 601, an upper guard plate 602, a vertical rod 603 and an arc 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. Arc rods 604 are evenly arranged on the vertical rods 603, and the ends of the arc rods 604 on adjacent vertical rods 603 are fitted together.

[0025] Local working principle: Under normal filtering conditions, multiple groups of lower guard plates 601 and upper guard plates 602 are all surrounded by 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.

[0026] In this embodiment, the outer side of the top cover 3 is evenly provided with sliding grooves 605 along the circumferential direction, and the inside 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.

[0027] 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.

[0028] In this embodiment, the expansion mechanism 7 includes an installation cavity 701, a turntable 702, an arc 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 arc grooves 703 in a ring array, and the sliders 704 are slidably installed inside the arc grooves 703. The outer side of the installation cavity 701 is evenly provided with sliding holes 706 along the circumferential direction, and the push rods 705 are slidably installed inside the sliding holes 706. 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.

[0029] 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.

[0030] In this embodiment, the shape of the slider 704 is cylindrical, the outer arc surface of the slider 704 fits with the inner side of the arc groove 703, and the inner side of the slider 704 is coated with a wear-resistant coating.

[0031] 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.

[0032] 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 at 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 inside 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. A 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 inside 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.

[0033] 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 gas 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.

[0034] 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. Two groups of rubber membranes 1103 are provided, and the third spring 1101 is located between the two groups of rubber membranes 1103.

[0035] Partial working principle: the top cover 3 and the mounting plate 10 are movably connected via the third spring 1101. When the pneumatic vibrator 9 is activated, the filter material 4 is driven to vibrate up and down. During the vibration, the rubber membrane 1103 ensures the sealing of the device.

[0036] 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 outer side of the mounting plate 10. The cross-sectional shape of the mounting holes 1201 is convex. The fourth spring 1202 is installed at the inner top of the mounting holes 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.

[0037] 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 passed 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.

[0038] 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 .

[0039] Partial working principle: After the mounting plate 10 is installed, the sealing ring 1001 fits tightly on the flower plate, ensuring the connection stability between the device and the flower plate.
