Description

Technical Field

[0001] This invention belongs to the field of dry dust collector filter bag cleaning technology, specifically relating to a cleaning and drying device for dry dust collector filter bags, and also relating to a cleaning and drying method for dry dust collector filter bags. Background Technology

[0002] Dry dust collector filter bags are the core filtration elements in baghouse dust collectors, primarily used for the dry separation of dust in industrial flue gas. They capture particulate matter through physical interception, diffusion, and electrostatic effects, achieving gas purification. They are typically made of high-temperature and corrosion-resistant synthetic fibers (such as polyester, PPS, and glass fiber), suitable for capturing fine, dry, non-fibrous dust, and widely used in industries such as cement, steel, power, and chemicals. With use, the pores in dry dust collector filter bags gradually become clogged with particulate matter, affecting the filtration efficiency. Therefore, regular cleaning of dry dust collector filter bags is usually necessary.

[0003] In the existing Chinese utility model patent application, CN218249016U discloses a high-efficiency cleaning device for filter bags. The device includes a base shell, a drain pipe fixedly connected to one side of the base shell, an electric push rod fixedly mounted on the top of the base shell, a top plate fixedly connected to the top of the electric push rod, a water tank fixedly connected to the top of the top plate, a valve fixedly connected to one side of the water tank, and a motor fixedly connected to the bottom of the top plate. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. This high-efficiency cleaning device for filter bags, through its base shell, drain pipe, electric push rod, top plate, motor, rotating shaft, brush bucket, support plate, fixing block, and filter bag body, enables high working efficiency. It can simultaneously place four filter bag bodies and use them in conjunction with four brush buckets for rapid cleaning, achieving a cleaning efficiency that individual cleaning methods cannot provide, thus meeting user needs.

[0004] However, the size of the mounting slot used for placing filter bags in the aforementioned cleaning device is fixed, meaning that the slot can only accommodate filter bags of a fixed size. This limits the cleaning device to cleaning filter bags of that specific size, making it unsuitable for cleaning filter bags of other sizes. This inflexibility makes the entire cleaning device unsuitable for use. Therefore, how to effectively clean and hold filter bags of different sizes is a crucial issue that needs to be addressed in the design of cleaning and drying devices for dry dust collector filter bags. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning and drying device for filter bags in dry dust collectors, which solves the problem that existing cleaning devices can only clean filter bags of fixed sizes and cannot clean filter bags of different sizes.

[0006] Another object of the present invention is to provide a method for cleaning and drying filter bags of dry dust collectors.

[0007] The technical solution adopted in this invention is a dry dust collector filter bag cleaning and drying device, including a filter bag cleaning shell, a rotating structure at the top of the filter bag cleaning shell, and several filter bag support structures connected to the bottom of the rotating structure.

The number of fixing plates 3 is equal to that of fixing blocks 1 and the positions are corresponding. Each fixing plate 3 is hinged to one end of connecting rod 2. Each fixing block 4 is hinged to the other end of connecting rod 2. Each fixing block 4 is connected to the corresponding support rod 2.

[0011] Each support rod 2 has a fixing pad 1 on its side wall away from the fixing block 4. The part of the threaded rod 1 located outside the threaded sleeve is covered with a dust cover, and the bottom of the dust cover is connected to the upper surface of the fixing plate 2.

[0012] Each scrubbing structure includes a rotating ring frame. A blind groove is provided at the bottom of the rotating ring frame along its circumference. The blind groove is fitted onto the side wall of the connecting frame two. A rotating rack is provided on the inner wall of the rotating ring frame along its circumference. A fixed plate three is provided at the top of the rotating ring frame. The fixed plate three is fitted onto the telescopic end of the electric push rod one. The rotating ring frame rotates relative to the fixed plate three. A motor three is connected to the lower surface of the fixed plate three. A rotating gear is connected to the output shaft of the motor three. The rotating gear meshes with the rotating rack. A fixed frame one is connected to the outer wall of the rotating ring frame. A square through groove two is provided at the bottom of the fixed frame one along its axial direction. An electric push rod two is provided inside the fixed frame one. The fixed end of the electric push rod two is connected to the outer wall of the rotating ring frame. A moving block is connected to the telescopic end of the electric push rod two. A connecting rod two is connected to the bottom of the moving block. The connecting rod two passes through the square through groove two. A cleaning brush is connected to the side of the connecting rod two near the filter bag support structure via the fixed rod two.

[0013] Each fixed structure includes an L-shaped fixed frame 2. One end of the fixed frame 2 is connected to the top of the support rod 2. A rotating rod 2 is inserted into the side wall of the other end of the fixed frame 2. A rotating handle is connected to the end of the rotating rod 2 away from the support rod 2. The end of the rotating rod 2 close to the support rod 2 is connected to one end of the threaded rod 2. The other end of the threaded rod 2 is rotatably connected to the side wall of the support rod 2. A fixed arc plate is threaded onto the threaded rod 2.

[0014] A fixing pad is provided on the side of the fixed arc plate near the support rod. Two sliding rods are slidably connected to the fixed arc plate. The two sliding rods are respectively located on both sides of the threaded rod. One end of each sliding rod is connected to the fixing frame, and the other end of each sliding rod is connected to the side wall of the support rod.

[0015] The bottom of the filter bag cleaning housing is evenly provided with several support rods. Two partition frames are connected at equal intervals along the circumference of the inner wall of the filter bag cleaning housing. The end of each partition frame away from the side wall of the filter bag cleaning housing is rotatably connected to the side wall of the rotating rod. The two partition frames divide the interior of the filter bag cleaning housing into three cavities. Each partition frame has a square through groove on its side wall, which extends through the top of the partition frame. The two side walls of the filter bag cleaning housing connected to the rotating rod are also provided with square through grooves, which extend through the top of the filter bag cleaning housing. Drain pipes are connected to the bottom of the middle cavity and one of the adjacent cavities. Several electric heating rods are provided on the inner wall of the other cavity without a drain pipe.

[0016] Another technical solution adopted in this invention is a method for cleaning and drying filter bags of dry dust collectors. Using the aforementioned cleaning and drying device for dry dust collector filter bags, the process is as follows: A central cavity is filled with clean water, and another cavity with a drain pipe is filled with cleaning liquid. The filter bag to be cleaned is fitted onto the filter bag support structure and fixed by a fixing structure. A rotating structure is activated to rotate the filter bag support structure into the cavity containing the cleaning liquid. A brushing structure is activated to perform brushing. After brushing, the filter bag is rotated into a cavity filled with clean water for further cleaning. After cleaning, the filter bag is rotated into a cavity equipped with an electric heating rod for drying. After drying, the clean filter bag is rotated out of the filter bag cleaning housing and removed.

[0017] The invention is further characterized by: The specific process of attaching the filter bag to be cleaned onto the filter bag support structure and fixing it with the fixing structure is as follows: attach the filter bag to be cleaned onto the outside of the second support rod, place the top of the filter bag between the fixed arc plate and the second support rod, rotate the handle to drive the second rotating rod to rotate, the second rotating rod to drive the second threaded rod to rotate, the second threaded rod to rotate to drive the fixed arc plate to move, the fixed arc plate to drive the second fixing pad to move, so that the second fixing pad abuts against the side wall of the filter bag, thereby fixing the filter bag. The rotating structure drives the filter bag support structure to rotate into the cavity containing the cleaning liquid. The specific process of starting the brushing structure for brushing is as follows: Motor 1 rotates, driving rotating rod 1 to rotate, rotating rod 1 drives connecting frame 1 to rotate, connecting frame 1 drives rotating ring to rotate, and rotating ring drives the fixed filter bag into the cavity containing the cleaning liquid. Electric push rod 1 extends to push the fixed filter bag into the cleaning liquid for soaking. When it is necessary to brush the filter bag, electric push rod 2 shortens, driving moving block to move, moving connecting rod 2 to move, connecting rod 2 to move fixed rod 2, and fixed rod 2 to move the cleaning brush, so that the cleaning brush adheres to the side wall of the fixed filter bag. Motor 3 rotates, driving rotating gear to rotate, rotating gear rotates in the rotating tooth groove, driving rotating ring frame to rotate, rotating ring frame to rotate, and rotating cleaning brush to brush the surface of the filter bag.

[0018] The beneficial effects of this invention are: (1) The cleaning and drying device for filter bags of dry dust collectors of the present invention rotates the rotating block to drive the threaded rod two to rotate, the threaded rod two to rotate to drive the fixed arc plate to move, the fixed arc plate to drive the fixed pad two to move, so that the fixed pad two abuts against the side wall of the filter bag, which facilitates the better fixing of the filter bag to be cleaned and prevents the filter bag from falling off the support rod two. (2) The cleaning and drying device for filter bags of the dry dust collector of the present invention drives the threaded sleeve to rotate by the rotation of the second motor, the rotation of the threaded sleeve drives the first threaded rod to move, the first threaded rod drives the second fixed plate to rise, and the movement of the second fixed plate pushes the second support rod to move through the first connecting rod, thereby adjusting the size of the filter bag support structure, so as to better adjust the size of the filter bag support structure according to the size of the filter bag to be cleaned. (3) The cleaning and drying device for the filter bag of the dry dust collector of the present invention moves the cleaning brush by extending and retracting the electric push rod two, so that the cleaning brush adheres to the side wall of the fixed filter bag. The motor three rotates and drives the rotating gear to rotate. The rotating gear rotates in the rotating tooth groove, drives the rotating ring frame to rotate, and the rotating ring frame rotates and drives the cleaning brush to rotate. The rotating cleaning brush gently brushes the surface of the filter bag, which facilitates the brushing and cleaning of the filter bag and makes the filter bag cleaner. (5) The cleaning and drying device for filter bags of the dry dust collector of the present invention can dry the cleaned filter bags by setting electric heating rods, thereby improving the drying efficiency of the filter bags.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 The present invention provides a cleaning and drying device for dry dust collector filter bags, the structure of which is as follows: Figure 1 As shown, the system includes a filter bag cleaning housing 1, which has a three-quarter circle cross-section and an open top. A rotating structure 5 is located at the top of the filter bag cleaning housing 1, and several filter bag support structures 6 are connected to the bottom of the rotating structure 5. Each filter bag support structure 6 is connected to a washing structure 7 and a fixing structure 8. The rotating structure 5 is used to rotate the filter bag support structure 6 for cleaning and drying. The filter bag support structure 6 is used to support filter bags of different sizes. The washing structure 7 is used to wash the filter bags. The fixing structure 8 is used to fix the filter bags supported by the filter bag support structure 6.

[0023] Example 2 Based on Example 1, such as Figure 2As shown, the rotating structure 5 includes a support frame 502, both ends of which are connected to the top of the filter bag cleaning housing 1. A motor 501 is mounted on the support frame 502. The output shaft of the motor 501 passes through the support frame 502 and is connected to a rotating rod 505. A connecting frame 503 is sleeved on the end of the rotating rod 505 near the motor 501. A rotating ring 504 is connected to the end of the connecting frame 503 away from the rotating rod 505. The rotating ring 504 is located between the bottom of the support frame 502 and the top of the filter bag cleaning housing 1. Several filter bag support structures 6 are evenly spaced at the bottom of the rotating ring 504 along its circumference. The rotating rod 505 is rotatably connected to the side end of the filter bag cleaning housing 1. The rotation of the motor 501 drives the rotating rod 505 to rotate, which in turn drives the connecting frame 503 to rotate. The connecting frame 503 drives the rotating ring 504 to rotate, and the rotating ring 504 drives the fixed filter bag into the filter bag cleaning housing 1.

[0024] Example 3 Based on Example 2, such as Figure 3 and 4As shown, each filter bag support structure 6 includes an electric push rod 601. The fixed end of the electric push rod 601 is connected to the rotating structure 5. The telescopic end of the electric push rod 601 is connected to the inner bottom of the cylindrical connecting frame 608 with a top opening. Several fixing rods 602 are connected to the bottom of the connecting frame 608 along its circumference. The ends of the fixing rods 602 away from the connecting frame 608 are connected to a fixing plate 603. A motor 604 is installed on the upper surface of the fixing plate 603. The output shaft of 04 passes through the fixing plate 603 and connects to one end of the threaded sleeve 605. The other end of the threaded sleeve 605 is threadedly connected to the threaded rod 607. The end of the threaded rod 607 away from the threaded sleeve 605 is connected to the fixing plate 606. Several fixing blocks 621 are evenly spaced on the upper surface of the fixing plate 606 along its circumference. Each fixing block 621 is hinged to one end of the connecting rod 622. The other end of each connecting rod 622 is hinged to a fixing block 624. Each of the two fixing blocks 624 is connected to a second support rod 625. The lower surface of the first fixing plate 603 is provided with three fixing plates 626 at equal intervals along its circumference, the same number as the first fixing blocks 621 and corresponding in position. Each three fixing plate 626 is hinged to one end of a second connecting rod 628, and the other end of each second connecting rod 628 is hinged to a fourth fixing block 627. Each fourth fixing block 627 is connected to a corresponding second support rod 625. The electric push rod 601 extends to push the filter bag into the cleaning solution for immersion. The rotation of motor 604 drives the threaded sleeve 605 to rotate, which in turn drives the threaded rod 607 to move. The threaded rod 607 then drives the fixed plate 606 to rise. The movement of the fixed plate 606, through connecting rod 622 and connecting rod 628, pushes the support rod 625 to move, thus opening the support rod 625. Conversely, the support rod 625 retracts. Therefore, the size of the filter bag support structure 6 can be adjusted according to the size of the filter bag to be cleaned, so as to accommodate filter bags of different sizes.

[0025] Example 4 Based on embodiment 3, each support rod 2 625 is provided with a fixing pad 1 623 on the side wall away from the fixing block 4 627. The fixing pad 1 623 is used to protect the filter bag to reduce wear. The threaded rod 1 607 located outside the threaded sleeve 605 is covered with a dustproof sleeve 611. The bottom of the dustproof sleeve 611 is connected to the upper surface of the fixing plate 2 606. The dustproof sleeve 611 provides dust protection for the threaded rod 1 607.

[0026] Example 5 Based on Example 4, such as Figure 3 , Figure 4 and Figure 5Each scrubbing structure 7 includes a rotating ring frame 701. A blind groove 724 is provided at the bottom end of the rotating ring frame 701 along its circumference. The blind groove 724 is fitted onto the side wall of the connecting frame 608. A rotating rack 705 is provided on the inner wall of the rotating ring frame 701 along its circumference. A fixing plate 721 is provided at the top end of the rotating ring frame 701. The fixing plate 721 is fitted onto the telescopic end of the electric push rod 601. The rotating ring frame 701 is positioned relative to the fixing plate 721. 1. A rotating fixed plate 721 has a motor 722 connected to its lower surface. The output shaft of the motor 722 is connected to a rotating gear 723, which meshes with a rotating rack 705. A fixed frame 702 is connected to the outer wall of the rotating ring frame 701. A square through groove 704 is provided along the axial direction at the bottom of the fixed frame 702. An electric push rod 703 is installed inside the fixed frame 702. The fixed end of the electric push rod 703 is connected to the rotating ring frame 701. The outer wall is connected to the electric push rod 703. The telescopic end of the electric push rod 703 is connected to the moving block 711. The bottom of the moving block 711 is connected to the connecting rod 712. The connecting rod 712 passes through the square through groove 704. The side of the connecting rod 712 near the filter bag support structure 6 is connected to the cleaning brush 714 through the fixing rod 713. The cleaning brush 714 is a soft brush. When the electric push rod 703 shortens, it drives the moving block 711 to move. The moving block 711 drives the connecting rod 712 to move. The connecting rod 712 drives the fixing rod 713 to move. The fixing rod 713 drives the cleaning brush 714 to move, so that the cleaning brush 714 fits against the side wall of the filter bag. The motor 722 rotates, which drives the rotating gear 723 to rotate. The rotating gear 723 rotates in the rotating tooth groove 705, which drives the rotating ring frame 701 to rotate. The rotating ring frame 701 rotates, which drives the cleaning brush 714 to rotate. The rotating cleaning brush 714 gently brushes the surface of the filter bag.

[0027] Example 6 Based on Example 5, such as Figure 6 As shown, each fixed structure 8 includes an L-shaped fixing frame 801. One end of the fixing frame 801 is connected to the top of the support rod 625. A rotating rod 804 is inserted into the side wall of the other end of the fixing frame 801. A rotating handle 802 is connected to the end of the rotating rod 804 away from the support rod 625. The end of the rotating rod 804 near the support rod 625 is connected to one end of a threaded rod 803. The other end of the threaded rod 803 is rotatably connected to the side wall of the support rod 625. A fixed arc plate 805 is threaded onto the threaded rod 803. The rotation of the rotating handle 802 drives the rotating rod 804 to rotate, which in turn drives the threaded rod 803 to rotate. The rotation of the threaded rod 803 causes the fixed arc plate 805 to move, thus the fixed arc plate 805 abuts against the filter bag, thereby clamping the filter bag between the fixed arc plate 805 and the support rod 625.

[0028] Example 7 Based on embodiment 6, a fixing pad 806 is provided on the side of the fixed arc plate 805 near the second support rod 625. The fixing pad 806 is used to protect the filter bag to reduce wear. Two sliding rods 807 are slidably connected on the fixed arc plate 805. The two sliding rods 807 are respectively provided on both sides of the threaded rod 803. One end of each sliding rod 807 is connected to the second fixing frame 801, and the other end of each sliding rod 807 is connected to the side wall of the second support rod 625. The sliding rods 807 are used to limit the movement path of the fixed arc plate 805, so that it moves along its axial direction, thereby improving the stability of the fixed arc plate 805.

[0029] Example 8 Based on Example 7, such as Figure 7 As shown, several support rods 2 are evenly arranged at the bottom of the filter bag cleaning housing 1. The support rods 2 are used to support the filter bag cleaning housing 1. Two partition frames 9 are connected at equal intervals along the circumference of the inner wall of the filter bag cleaning housing 1. The end of each partition frame 9 away from the side wall of the filter bag cleaning housing 1 is rotatably connected to the side wall of the rotating rod 505. The two partition frames 9 divide the interior of the filter bag cleaning housing 1 into three cavities. A square through groove 3 is provided on the side wall of each partition frame 9. The square through groove 3 passes through the top of the partition frame 9. Two partition frames 9 connected to the rotating rod 505 on the filter bag cleaning housing 1 are connected to the rotating rod 505. Square through-slots 3 are provided on the side walls. Square through-slots 3 pass through the top of the filter bag cleaning housing 1. Square through-slots 3 are used to allow the filter bag support structure 6 to enter different cavities through the partition frame 9. Drain pipes 11 are connected to the bottom of the middle cavity and one of its adjacent cavities. Several electric heating rods 10 are provided on the inner wall of the other cavity without drain pipes 11. The electric heating rods 10 are used to dry the cleaned filter bags. The cavity located on the side with drain pipes 11 is filled with cleaning liquid for cleaning the filter bags. The middle cavity is filled with clean water for rinsing the cleaning liquid off the filter bags.

[0030] Example 9 Based on embodiment 8, a rubber strip is provided between the separator 9 and the filter bag cleaning housing 1 to ensure that it remains sealed during the rotation of the rotating rod 505, thus preventing leakage of cleaning liquid and clean water in the cavity; a shielding door 4 is hinged to the side wall of the square through groove 3.

[0031] Example 10 The present invention provides a method for cleaning and drying filter bags of a dry dust collector, using any one of the dry dust collector filter bag cleaning and drying devices described in Examples 1 to 9 above. The process is as follows: the middle cavity is filled with clean water, and another cavity equipped with a drain pipe 11 is filled with cleaning liquid. The filter bag to be cleaned is fitted onto the filter bag support structure 6 and fixed by the fixing structure 8. The rotating structure 5 is activated to rotate the filter bag support structure 6 into the cavity filled with cleaning liquid. The brushing structure 7 is activated to perform brushing. After brushing, the filter bag is rotated into the cavity filled with clean water for cleaning. After cleaning, the filter bag is rotated into the cavity equipped with an electric heating rod 10 for drying. After drying, the clean filter bag is rotated out of the filter bag cleaning housing 1 and removed.

[0032] The specific process of attaching the filter bag to be cleaned onto the filter bag support structure 6 and fixing it through the fixing structure 8 is as follows: The filter bag to be cleaned is attached to the outside of the second support rod 625. The second motor 604 rotates, driving the threaded sleeve 605 to rotate. The rotation of the threaded sleeve 605 drives the first threaded rod 607 to move. The first threaded rod 607 drives the second fixing plate 606 to rise. The movement of the second fixing plate 606 pushes the second support rod 625 to move through the first connecting rod 622 and the second connecting rod 628. The second support rod 625 is then spread open until it meets the size of the filter bag. The top of the filter bag is placed between the fixed arc plate 805 and the second support rod 625. The rotating handle 802 drives the second rotating rod 804 to rotate. The second rotating rod 804 drives the second threaded rod 803 to rotate. The rotation of the second threaded rod 803 drives the fixed arc plate 805 to move. The fixed arc plate 805 drives the second fixing pad 806 to move, so that the second fixing pad 806 abuts against the side wall of the filter bag, thereby fixing the filter bag. The rotating structure 5 drives the filter bag support structure 6 to rotate into the cavity containing the cleaning liquid, activating the brushing structure 7 for brushing. The specific process is as follows: Motor 501 rotates, driving rotating rod 505 to rotate; rotating rod 505 drives connecting frame 503 to rotate; connecting frame 503 drives rotating ring 504 to rotate; rotating ring 504 drives the fixed filter bag into the cavity containing the cleaning liquid; electric push rod 601 extends to push the fixed filter bag into the cleaning liquid for soaking. When brushing of the filter bag is required, electric push rod 703 shortens. The moving block 711 moves, the moving block 711 moves the connecting rod 712, the connecting rod 712 moves the fixing rod 713, and the fixing rod 713 moves the cleaning brush 714, so that the cleaning brush 714 fits against the side wall of the fixed filter bag. The motor 722 rotates, which drives the rotating gear 723 to rotate. The rotating gear 723 rotates in the rotating tooth groove 705, which drives the rotating ring frame 701 to rotate. The rotating ring frame 701 rotates, which drives the cleaning brush 714 to rotate. The rotating cleaning brush 714 brushes the surface of the filter bag. The process of rotating the filter bag support structure 6 to a cavity filled with cleaning liquid after brushing is the same as the process of rotating structure 5 driving filter bag support structure 6 to rotate to a cavity filled with cleaning liquid for cleaning. After cleaning, the filter bag is rotated into the cavity equipped with the electric heating rod 10 for drying. After drying, the clean filter bag is rotated out of the filter bag cleaning housing 1. The rotation process is the same as the rotation process in which the rotating structure 5 drives the filter bag support structure 6 to rotate into the cavity containing the cleaning liquid.
