Description

Technical Field

[0001] The invention relates to the technical field of dust filtering equipment, and in particular to a dust filtering equipment and a production process for ingredients used in powder coating production. Background Art

[0002] During the batching process of powder coating production, a large amount of dust will be generated. This dust will not only pollute the production environment and endanger the health of workers, but may also cause safety accidents such as dust explosions. Traditional filtering equipment has low filtering efficiency and poor cleaning effect, and cannot meet the requirements of environmental protection and safe production. Therefore, an efficient and reliable dust filtering equipment is urgently needed to solve the above problems.

[0003] A dust filtering device is disclosed in the patent application with the publication number of CN118236785A, including a filter support, a filter box, an air inlet duct, a spray pipe, a recovery water tank and a fan, a primary filter and two V-type high-efficiency filters are arranged in the filter box, a quick-release assembly is arranged between each V-type high-efficiency filter and the filter support, the quick-release assembly includes a filter housing and two operating rods, two L-shaped brackets are arranged on both sides of the bottom of the filter housing, the V-type high-efficiency filter is installed between the two L-shaped brackets in a pull-out manner, a plurality of slots are arranged on the crossbeam of each L-shaped bracket, a plurality of holders are arranged at the bottom of the crossbeam of each L-shaped bracket, and an operating rod is movably inserted on all the holders on the same side, a cam inserted into the slot is arranged on the operating rod, a handle is arranged on one side of the operating rod, two disassembly ports 1 are arranged on the side of the filter box, and a sealing door 1 is detachably connected to the disassembly port 1. The present invention realizes the quick disassembly and quick installation of the V-type high-efficiency filter.

[0004] The prior art has the following defects: Poor cleaning efficiency leads to blockage: Existing devices generally use pulse airflow to clean the filter bags. Pulse cleaning cannot ensure that all filter bags are cleaned evenly and effectively. Dust in some filter bags is not completely removed, which leads to increased local resistance and affects the overall filtration efficiency. Pulse cleaning requires compressed air. The generation and delivery of compressed air consumes a lot of energy. Especially when cleaning is frequent, the operating cost increases significantly. Therefore, it is necessary to set up a mechanical cycle cleaning and easy to replace filter bag structure, which can realize continuous and stable cleaning operation, remove dust on the surface of the filter bag in time, avoid excessive dust accumulation, maintain good filtration performance, and quickly replace the filter bag when it is damaged or seriously clogged, reducing downtime and ensuring continuous operation of the equipment, thereby reducing maintenance costs and improving filtration efficiency.

[0005] It is impossible to improve the filtration efficiency by tilting the filter bag angle when necessary: ​​When the production task is urgent, in order to complete the production of a large number of products on time, the speed of the filtration process needs to be accelerated to ensure the overall progress. The existing equipment can only improve the efficiency by increasing the suction force. Increasing the suction force means that equipment such as fans need to operate at higher power, which greatly increases energy consumption and causes great damage to the filter bags. Strong wind force can easily cause the filter bags to shake violently and wear faster, shortening their service life. Therefore, it is necessary to set a structure that can tilt the filter bag angle to make the process channel more unobstructed, greatly improve the filtration efficiency, and make it easier for impurities to fall off the surface of the filter bag under the action of gravity, reducing accumulation, and extending the service life of the filter bag, thereby ensuring production continuity and improving overall production efficiency. Summary of the invention

[0006] In view of the problems in the prior art such as poor cleaning efficiency leading to blockage and the inability to improve the filtration efficiency by tilting the filter bag angle when necessary, a dust filtration equipment and production process for ingredients used in powder coating production is proposed.

[0007] On the one hand, the present application provides a dust filtering device for ingredients used in powder coating production, the purpose of which is to achieve continuous and stable cleaning operations through the provided filtering mechanism, timely remove dust from the filter bag surface, avoid excessive dust accumulation, maintain good filtering performance, and quickly replace the filter bag when it is damaged or seriously clogged, thereby reducing downtime and ensuring continuous operation of the equipment, thereby reducing maintenance costs and improving filtering efficiency. By means of the provided flipping mechanism, the filter bag angle can be tilted when necessary to make the process channel more unobstructed, greatly improving the filtering efficiency, and making it easier for impurities to separate from the filter bag surface under the action of gravity, thereby reducing accumulation and extending the service life of the filter bag, thereby ensuring production continuity and improving overall production efficiency.

[0008] The technical solution of the present invention is: a powder dust filtering device for ingredients used in powder coating production, comprising a bracket, a shell component arranged above the bracket, a flip mechanism installed inside the shell component, and a plurality of filtering mechanisms arranged inside the flip mechanism, wherein the filtering mechanism continuously filters dust through a transmission cycle, and the flip mechanism is used to adjust the filtering mechanism to flip and tilt, the shell component comprises a dust removal box fixedly connected to the top of the bracket, the flip mechanism comprises a flip plate rotatably connected to the inner wall of the dust removal box, and the dust removal box is provided with a dust air chamber and a clean air chamber on both sides of the flip plate; The filtering mechanism includes a supporting assembly and a circulation assembly arranged inside the flip plate, the supporting assembly includes a supporting frame and a disassembly frame slidably connected to the inner wall of the flip plate, the two are bolted together, a filter membrane circulation cavity and two symmetrically arranged clean air flow cavities are provided inside the supporting frame, and a scraping plate is fixedly installed between one end of the supporting frame and the disassembly frame in the dust and gas chamber.

[0009] By adopting the above scheme, through the setting of the filtering mechanism, as the circulation component circulates, when it passes through the surface of the clean air flow cavity, the scraper plate fixed between the support frame and the disassembly frame will scrape off the dust attached to the surface of the breathable filter membrane, and the filter membrane circulation cavity provides a space for the filter membrane transmission belt in the circulation component to circulate, thereby avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect.

[0010] Furthermore, the circulation component includes a fixing plate fixedly connected to the outer wall of the support frame, the outer wall of the fixing plate is fixedly connected to two micro motors, and the output shafts of the two micro motors are both sleeved with driving gears.

[0011] Furthermore, the circulation component also includes two movable gears rotatably connected between the support frame and the disassembly frame, and a filter membrane transmission belt is transmission-connected between the two movable gears and the corresponding driving gears, and the surface of the filter membrane transmission belt is covered with a breathable filter membrane.

[0012] By adopting the above scheme, the micro motor is started through the circulation component, and its output shaft drives the driving gear to rotate. The driving gear is connected to the movable gear through the filter membrane transmission belt, thereby driving the movable gear to rotate, so that the filter membrane transmission belt performs a circulating motion. The surface of the filter membrane transmission belt is covered with a breathable filter membrane. When the dust-laden airflow passes through the breathable filter membrane, the dust is intercepted, and the clean air passes through the breathable filter membrane into the clean air flow cavity inside the support frame, thereby realizing the separation of dust and clean gas.

[0013] Furthermore, the flipping mechanism also includes a push-pull assembly arranged inside the flip plate, and the push-pull assembly includes a plurality of first rotating wheels and a second rotating wheel rotatably connected to the inside of the flip plate, and the inner walls of the first rotating wheels and the second rotating wheels are both provided with through holes, and the inner walls of the plurality of through holes are respectively clamped with multiple groups of support frames and disassembly frames.

[0014] Furthermore, the surfaces of the first rotating wheel and the second rotating wheel are each provided with a plurality of tooth grooves, and the plurality of first rotating wheels and the second rotating wheels on the same horizontal line are respectively connected with long racks and short racks through tooth groove transmission, and vertical bars are connected between one ends of the plurality of long racks and short racks, and the plurality of long racks, short racks and vertical bars are all slidably connected to the inner wall of the flip plate.

[0015] Furthermore, the inner wall of the vertical bar is threadedly connected to two threaded rods, and the ends of the two threaded rods close to the first rotating wheel are rotatably connected to the inner wall of the flip plate, and a synchronous transmission belt is transmitted between the two threaded rods, and one end of one of the threaded rods away from the first rotating wheel is fixedly connected to a servo motor.

[0016] By adopting the above scheme, the servo motor is started to drive the threaded rod connected to it to rotate, and through the synchronous transmission belt, the other threaded rod also rotates synchronously. The rotation of the threaded rod causes the vertical bar threadedly connected to it to move, and the vertical bar drives the long rack and the short rack to slide on the inner wall of the flip plate. The long rack and the short rack engage with the first rotating wheel and the second rotating wheel through the tooth grooves, driving them to rotate. Since the through holes of the first rotating wheel and the second rotating wheel are clamped with the support frame and the disassembly frame, the flipping of the filter mechanism is realized, so that the two clean air flow chambers alternately perform filtering and cleaning operations.

[0017] Furthermore, the dust removal box is fixedly connected to the outer surface of the servo motor near the sealing outer cover and the flip hand wheel, the inner wall of the sealing outer cover is provided with a guide groove, the inner wall of the dust removal box is provided with a penetration groove corresponding to the guide groove, the servo motor and its output shaft are respectively slidably connected to the inner walls of the guide groove and the penetration groove, and the output shaft of the flip hand wheel penetrates the dust removal box and is fixedly connected to the bottom of the flip plate.

[0018] By adopting the above scheme, through the setting of the flip mechanism, the operator can turn the flip handwheel, and its output shaft drives the flip plate to rotate, so that the filtering mechanism is tilted. When the flip plate flips, the guide groove on the inner wall of the sealing outer cover and the corresponding penetration groove on the inner wall of the dust removal box cooperate with each other, providing a sliding channel for the servo motor and its output shaft, and the sealing outer cover provides a relatively closed space for the servo motor, reducing the adverse effects of the external environment on the motor, and preventing the dust removal box from being connected to the outside.

[0019] Furthermore, the housing assembly also includes an air outlet pipe and an air inlet pipe fixedly connected to the outer wall of the dust removal box, the air outlet pipe is connected to the clean air chamber, and the air inlet pipe is connected to the dust air chamber.

[0020] Furthermore, an ash hopper and an ash discharge device are fixedly connected to the bottom of the dust removal box in sequence, and an inspection door is provided on the outer surface of the dust removal box close to the clean air chamber.

[0021] By adopting the above scheme, through the setting of the shell assembly, the dust-containing airflow generated in the powder coating production process is continuously discharged into the dust gas chamber in the dust removal box through the air inlet pipe for filtration. The clean gas after filtration is discharged from the equipment through the air outlet pipe connected to the clean air chamber. In addition, the setting of the inspection door facilitates the inspection and maintenance of the interior of the equipment.

[0022] Another aspect of the present application provides a production process of a dust filtering device for ingredients used in powder coating production, using a dust filtering device for ingredients used in powder coating production, comprising the following steps: Step 1: The dust generated by powder coating production is continuously discharged into the dust chamber; Step 2: The circulation component operates to continuously filter the dust-laden airflow; Step 3: The dust-laden airflow is filtered by the filter mechanism and discharged into the clean air chamber; Step 4: After the circulating components pass through the surface of the clean air flow cavity, the dust is scraped off by the dust scraper; Step 5: The flipping mechanism drives the two clean air flow chambers to flip to achieve alternating filtration; Step 6: The flipping mechanism drives the flipping plate to flip, so that the filtering mechanism is tilted to improve the filtering efficiency.

[0023] By adopting the above scheme, the dust-laden airflow generated in the production process of powder coatings is continuously discharged into the dust gas chamber in the dust removal box through the air inlet pipe through the micro-motor in the circulation component, and its output shaft drives the driving gear to rotate. The driving gear is connected to the movable gear through the filter membrane transmission belt, thereby driving the movable gear to rotate, so that the filter membrane transmission belt performs a circulating motion. The surface of the filter membrane transmission belt is covered with a breathable filter membrane. When the dust-laden airflow passes through the breathable filter membrane, the dust is intercepted, and the clean air passes through the breathable filter membrane into the clean air circulation cavity inside the support frame, thereby realizing the separation of dust and clean gas. With the circulating motion of the filter membrane transmission belt, when it passes through the surface of the clean air circulation cavity, the support frame The scraper plate fixed between the filter and the disassembly frame will scrape off the dust attached to the surface of the breathable filter membrane. The scraped dust falls into the ash hopper at the bottom of the dust removal box under the action of gravity, and then is discharged from the equipment through the ash discharge device, avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect. To improve the filtering efficiency, the push-pull assembly can be operated to flip the filter mechanism so that the two clean air flow cavities alternately perform filtering and cleaning operations. When it is necessary to further improve the filtering efficiency, the operator can turn the flip handwheel, and its output shaft drives the flip plate to rotate to tilt the filter mechanism. After the filter mechanism is tilted, the channel is smoother, and impurities are more easily separated from the filter membrane surface under the action of gravity, reducing accumulation and further improving the filtering efficiency.

[0024] Beneficial effects of the present invention: 1. Through the filter mechanism set up, the dust gas chamber in the dust removal box is continuously discharged through the air inlet pipe. The micro motor in the circulation component is started, and its output shaft drives the driving gear to rotate. The driving gear is connected to the movable gear through the filter membrane transmission belt, thereby driving the movable gear to rotate, so that the filter membrane transmission belt performs a circulating motion. The surface of the filter membrane transmission belt is covered with a breathable filter membrane. When the dust-laden airflow passes through the breathable filter membrane, the dust is intercepted, and the clean air passes through the breathable filter membrane into the clean air circulation cavity inside the support frame, thereby realizing the separation of dust and clean gas. With the circulating motion of the filter membrane transmission belt, when it passes through the surface of the clean air circulation cavity, the scraper plate fixed between the support frame and the disassembly frame will scrape off the dust attached to the surface of the breathable filter membrane, and the scraped dust falls into the ash hopper at the bottom of the dust removal box under the action of gravity, and then is discharged from the equipment through the ash discharge device, thereby avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect.

[0025] 2. Through the push-pull assembly, the servo motor can be started to drive the threaded rod connected to it to rotate. Through the synchronous transmission belt, the other threaded rod also rotates synchronously. The rotation of the threaded rod causes the vertical bar threadedly connected to it to move. The vertical bar drives the long rack and the short rack to slide on the inner wall of the flip plate. The long rack and the short rack engage with the first rotating wheel and the second rotating wheel through the tooth grooves, driving them to rotate. Since the through holes of the first rotating wheel and the second rotating wheel are clamped with the support frame and the disassembly frame, the flipping of the filter mechanism is realized, so that the two clean air flow chambers perform filtering and cleaning operations alternately.

[0026] 3. Through the set flip mechanism, when it is necessary to further improve the filtering efficiency, the operator can turn the flip handwheel, and its output shaft drives the flip plate to rotate, so that the filtering mechanism is tilted. After the filtering mechanism is tilted, the channel is smoother, and impurities are more easily separated from the filter membrane surface under the action of gravity, reducing accumulation and further improving the filtering efficiency. When the flip plate is flipped, the guide groove on the inner wall of the sealing cover and the corresponding penetration groove on the inner wall of the dust removal box cooperate with each other to provide a sliding channel for the servo motor and its output shaft, and the sealing cover provides a relatively closed space for the servo motor, reducing the adverse effects of the external environment on the motor, while avoiding the dust removal box from being connected to the outside.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1 - Fig.12 , which is the first embodiment of the present invention, provides a dust filtering device for ingredients used in powder coating production, including a bracket 1, a shell assembly 2 arranged above the bracket 1, a flip mechanism 3 installed inside the shell assembly 2, and multiple filtering mechanisms 4 arranged inside the flip mechanism 3, the filtering mechanism 4 continuously filters dust through a transmission cycle, the flip mechanism 3 is used to adjust the filtering mechanism 4 to flip and tilt, the shell assembly 2 includes a dust removal box 21 fixedly connected to the top of the bracket 1, the flip mechanism 3 includes a flip plate 31 rotatably connected to the inner wall of the dust removal box 21, and the interior of the dust removal box 21 is provided with a dust chamber 27 and a clean air chamber 28 on both sides of the flip plate 31.

[0031] Reference Figure 5 - Figure 7 The filtering mechanism 4 includes a supporting assembly 41 and a circulation assembly 42 arranged inside the flip plate 31. The supporting assembly 41 includes a supporting frame 411 and a disassembly frame 412 which are slidably connected to the inner wall of the flip plate 31. The two are bolted together. A filter membrane circulation chamber 414 and two symmetrically arranged clean air flow chambers 413 are provided inside the supporting frame 411. A scraping plate 415 is fixedly installed between one end of the supporting frame 411 and the disassembly frame 412 in the dust chamber 27.

[0032] Specifically, the support assembly 41 includes a support frame 411 and a disassembly frame 412, both of which are matched with the inner wall of the flip plate 31 in a sliding connection manner. When the filter mechanism 4 needs to be inspected or parts need to be replaced, the staff can easily slide the support frame 411 and the disassembly frame 412 out of the flip plate 31; the two clean air circulation chambers 413 are symmetrically arranged to alternately perform filtering and cleaning operations. When one clean air circulation chamber 413 is filtering, the other clean air circulation chamber 413 can be cleaned to ensure the continuity of the filtering work.

[0033] Through the filter mechanism 4 that is set up, as the circulation component 42 circulates, when it passes through the surface of the clean air circulation cavity 413, the scraper plate 415 fixed between the support frame 411 and the disassembly frame 412 will scrape off the dust attached to the surface of the breathable filter membrane 424, and the filter membrane circulation cavity 414 provides a space for the filter membrane transmission belt 425 in the circulation component 42 to circulate, thereby avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect.

[0034] Reference Figure 5 - Figure 7 The circulation component 42 includes a fixed plate 421 fixedly connected to the outer wall of the support frame 411, and two micro motors 422 are fixedly connected to the outer wall of the fixed plate 421. The output shafts of the two micro motors 422 are both sleeved with driving gears 423. The circulation component 42 also includes two movable gears 426 rotatably connected between the support frame 411 and the disassembly frame 412. The two movable gears 426 and the corresponding driving gears 423 are both transmission-connected with a filter membrane transmission belt 425, and the surface of the filter membrane transmission belt 425 is covered with a breathable filter membrane 424.

[0035] Specifically, the breathable filter membrane 424 has good air permeability, allowing gas to pass smoothly while effectively intercepting dust particles. As the filter membrane drive belt 425 circulates, the breathable filter membrane 424 can continuously contact the dust-containing gas to achieve efficient filtration operations. This cyclic rotation method enables each part of the breathable filter membrane 424 to be fully utilized, avoiding a decrease in filtration effect due to local excessive use.

[0036] By setting up the circulation component 42, the micro motor 422 is started, and its output shaft drives the driving gear 423 to rotate. The driving gear 423 is connected to the movable gear 426 through the filter membrane transmission belt 425, thereby driving the movable gear 426 to rotate, so that the filter membrane transmission belt 425 performs a circulating motion. The surface of the filter membrane transmission belt 425 is covered with a breathable filter membrane 424. When the dust-laden airflow passes through the breathable filter membrane 424, the dust is intercepted, and the clean air passes through the breathable filter membrane 424 into the clean air circulation cavity 413 inside the support frame 411, thereby realizing the separation of dust and clean gas.

[0037] Reference Figure 8 - Fig.10 The flip mechanism 3 also includes a push-pull assembly 32 disposed inside the flip plate 31, and the push-pull assembly 32 includes a plurality of first rotating wheels 326 and a second rotating wheel 327 rotatably connected to the inside of the flip plate 31, and the inner walls of the first rotating wheels 326 and the second rotating wheels 327 are both provided with through holes 328, and the inner walls of the plurality of through holes 328 are respectively engaged with the plurality of support frames 411 and the disassembly frame 412, and the surfaces of the first rotating wheels 326 and the second rotating wheels 327 are both provided with a plurality of tooth grooves 329, and the plurality of first rotating wheels 326 and the second rotating wheels 327 on the same horizontal line are respectively connected through the tooth grooves 328. 29 is connected to the transmission with a long rack 324 and a short rack 325, and a vertical bar is connected between one end of the multiple long racks 324 and the short racks 325. The multiple long racks 324, the short racks 325 and the vertical bar are all slidably connected to the inner wall of the flip plate 31, and the inner wall of the vertical bar is threadedly connected with two threaded rods 323. One end of the two threaded rods 323 close to the first rotating wheel 326 is rotatably connected to the inner wall of the flip plate 31. A synchronous transmission belt 322 is connected to the transmission between the two threaded rods 323, and one end of one threaded rod 323 away from the first rotating wheel 326 is fixedly connected to the servo motor 321.

[0038] By starting the servo motor 321, the threaded rod 323 connected thereto is driven to rotate, and through the synchronous transmission belt 322, the other threaded rod 323 also rotates synchronously. The rotation of the threaded rod 323 causes the vertical bar threadedly connected thereto to move, and the vertical bar drives the long rack 324 and the short rack 325 to slide on the inner wall of the flip plate 31. The long rack 324 and the short rack 325 engage with the first rotating wheel 326 and the second rotating wheel 327 through the tooth groove 329, driving them to rotate. Since the through holes 328 of the first rotating wheel 326 and the second rotating wheel 327 are clamped with the support frame 411 and the disassembly frame 412, the flipping of the filter mechanism 4 is realized, so that the two clean air flow chambers 413 perform filtering and cleaning operations alternately.

[0039] Reference Fig.11 A sealing cover 35 and a flip hand wheel 33 are fixedly connected to the outer surface of the dust removal box 21 near the servo motor 321. A guide groove 36 is opened on the inner wall of the sealing cover 35. A penetration groove 34 is opened on the inner wall of the dust removal box 21 corresponding to the guide groove 36. The servo motor 321 and its output shaft are respectively slidably connected to the inner walls of the guide groove 36 and the penetration groove 34. The output shaft of the flip hand wheel 33 penetrates the dust removal box 21 and is fixedly connected to the bottom of the flip plate 31.

[0040] Through the set flip mechanism 3, the operator can turn the flip hand wheel 33, and its output shaft drives the flip plate 31 to rotate, so that the filter mechanism 4 is tilted. When the flip plate 31 flips, the guide groove 36 on the inner wall of the sealing outer cover 35 and the corresponding penetration groove 34 on the inner wall of the dust removal box 21 cooperate with each other, providing a sliding channel for the servo motor 321 and its output shaft, and the sealing outer cover 35 provides a relatively closed space for the servo motor 321, reducing the adverse effects of the external environment on the motor, and preventing the dust removal box 21 from being connected to the outside.

[0041] Reference Figure 2 - Figure 3 The shell assembly 2 also includes an air outlet pipe 23 and an air inlet pipe 26 fixedly connected to the outer wall of the dust removal box 21. The air outlet pipe 23 is connected to the clean air chamber 28, and the air inlet pipe 26 is connected to the dust air chamber 27. The bottom of the dust removal box 21 is fixedly connected with an ash hopper 24 and an ash discharge device 25 in sequence. The outer surface of the dust removal box 21 near the clean air chamber 28 is provided with an inspection door 22.

[0042] Through the provided outer shell assembly 2, the dust-laden airflow generated in the powder coating production process is continuously discharged into the dust and gas chamber 27 in the dust removal box 21 through the air inlet pipe 26 for filtration, and the clean gas after filtration is discharged from the equipment through the air outlet pipe 23 connected to the clean air chamber 28. In addition, the provision of the inspection door 22 facilitates the inspection and maintenance of the interior of the equipment.

[0043] During use, the dust-laden airflow generated during the production of the powder coating is continuously discharged into the dust and gas chamber 27 in the dust removal box 21 through the air inlet pipe 26. The micro motor 422 in the circulation component 42 is started, and its output shaft drives the driving gear 423 to rotate. The driving gear 423 is connected to the movable gear 426 through the filter membrane transmission belt 425, thereby driving the movable gear 426 to rotate, so that the filter membrane transmission belt 425 performs a circulating motion. The surface of the filter membrane transmission belt 425 is covered with a breathable filter membrane 424. When the dust-laden airflow passes through the breathable filter membrane 424, the dust is intercepted, and the clean air passes through the breathable filter membrane 424 into the clean air circulation cavity 413 inside the support frame 411, so as to separate the dust from the clean gas. As the filter membrane transmission belt 425 circulates, when it passes through the surface of the clean air circulation cavity 413, The scraper plate 415 fixed between the support frame 411 and the disassembly frame 412 will scrape off the dust attached to the surface of the breathable filter membrane 424. The scraped dust falls into the ash hopper 24 at the bottom of the dust removal box 21 under the action of gravity, and then is discharged from the equipment through the ash discharge device 25, thereby avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect. In order to improve the filtering efficiency, the push-pull assembly 32 can be operated to realize the flipping of the filter mechanism 4, so that the two clean air flow chambers 413 alternately perform filtering and cleaning operations. When it is necessary to further improve the filtering efficiency, the operator can turn the flip handwheel 33, and its output shaft drives the flip plate 31 to rotate, so that the filter mechanism 4 is tilted. After the filter mechanism 4 is tilted, the channel is smoother, and impurities are more easily separated from the filter membrane surface under the action of gravity, thereby reducing accumulation and further improving the filtering efficiency.

[0044] Example 2, reference Figure 1 - Fig.12 , provides a production process of a dust filtering device for ingredients used in powder coating production, using a dust filtering device for ingredients used in powder coating production, comprising the following steps: Step 1: Dust generated by powder coating production is continuously discharged into the dust chamber 27; Step 2: The circulation component 42 operates to continuously filter the dust-laden airflow; Step 3: The dust-laden airflow is filtered by the filter mechanism 4 and discharged into the clean air chamber 28; Step 4: After the circulation component 42 passes through the surface of the clean air flow cavity 413, the dust is scraped off by the dust scraping plate 415; Step 5: The flipping mechanism 3 drives the two clean air flow chambers 413 to flip to achieve alternating filtration; Step 6: The turning mechanism 3 drives the turning plate 31 to turn over, so that the filtering mechanism 4 is tilted to improve the filtering efficiency.

[0045] Working principle of the present invention: The dusty airflow generated during the production process of powder coatings is continuously discharged into the dust and gas chamber 27 in the dust removal box 21 through the air inlet pipe 26. The micro motor 422 in the circulation component 42 is started, and its output shaft drives the driving gear 423 to rotate. The driving gear 423 is connected to the movable gear 426 through the filter membrane transmission belt 425, thereby driving the movable gear 426 to rotate, so that the filter membrane transmission belt 425 performs a circulating motion. The surface of the filter membrane transmission belt 425 is covered with a breathable filter membrane 424. When the dusty airflow passes through the breathable filter membrane 424, the dust is intercepted, and the clean air passes through the breathable filter membrane 424 into the clean air circulation cavity 413 inside the support frame 411, thereby realizing the separation of dust and clean gas.

[0046] As the filter membrane transmission belt 425 circulates, when it passes through the surface of the clean air circulation cavity 413, the scraper plate 415 fixed between the support frame 411 and the disassembly frame 412 will scrape off the dust attached to the surface of the breathable filter membrane 424, and the scraped dust falls into the ash hopper 24 at the bottom of the dust removal box 21 under the action of gravity, and is then discharged from the equipment through the ash discharge device 25, thereby avoiding excessive accumulation of dust on the filter membrane and ensuring the stability of the filtering effect.

[0047] To improve the filtering efficiency, the servo motor 321 can be started to drive the threaded rod 323 connected to it to rotate. Through the synchronous transmission belt 322, the other threaded rod 323 also rotates synchronously. The rotation of the threaded rod 323 causes the vertical bar threadedly connected to it to move, and the vertical bar drives the long rack 324 and the short rack 325 to slide on the inner wall of the flip plate 31. The long rack 324 and the short rack 325 engage with the first rotating wheel 326 and the second rotating wheel 327 through the tooth groove 329, driving them to rotate. Since the through holes 328 of the first rotating wheel 326 and the second rotating wheel 327 are clamped with the support frame 411 and the disassembly frame 412, the flipping of the filter mechanism 4 is realized, so that the two clean air flow chambers 413 alternately perform filtering and cleaning operations.

[0048] When the filtration efficiency needs to be further improved, the operator can turn the flip handwheel 33, and its output shaft drives the flip plate 31 to rotate, so that the filter mechanism 4 is tilted. After the filter mechanism 4 is tilted, the channel is more unobstructed, and impurities are more easily separated from the filter membrane surface under the action of gravity, which reduces accumulation and further improves the filtration efficiency. The clean gas after filtration is discharged from the equipment through the outlet pipe 23 connected to the clean air chamber 28. In addition, the setting of the inspection door 22 facilitates the inspection and maintenance of the inside of the equipment.

[0049] When the flip plate 31 flips, the guide groove 36 on the inner wall of the sealing outer cover 35 and the corresponding penetration groove 34 on the inner wall of the dust removal box 21 cooperate with each other to provide a sliding channel for the servo motor 321 and its output shaft, and the sealing outer cover 35 provides a relatively closed space for the servo motor 321, reducing the adverse effects of the external environment on the motor and preventing the dust removal box 21 from being connected to the outside.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
