Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, and in particular to a dust collector filter bag with an acid and alkali resistant composite structure for paint booths. Background Technology

[0002] The acid and alkali resistant paint booth composite structure dust collector filter bag is a high-efficiency filtration component designed specifically for treating paint booth exhaust gas containing acid and alkali corrosion and organic solvents. This filter bag can operate stably in paint booth environments with relative humidity of 90% and containing highly corrosive media such as SO3. It is widely used in paint mist treatment in industries such as automotive painting and furniture manufacturing, taking into account both high-efficiency filtration and long-cycle operation requirements.

[0003] However, when the dew point temperature of the flue gas is higher than the surface of the filter bag during processing, water vapor condensation can easily cause moist or hygroscopic dust to adhere to the filter bag and form a dense layer, leading to filter bag blockage, loss of air permeability, and failure of dust removal, requiring complete replacement. Long-term operation can cause filter bag shrinkage, installation failure, and flue gas short circuit, increasing equipment maintenance costs and downtime risks. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where, when the dew point temperature of the flue gas is higher than the surface of the filter bag during processing, water vapor condenses and easily causes moist or hygroscopic dust to adhere to the filter bag, forming a dense layer, leading to filter bag blockage, loss of air permeability, and failure of dust removal, requiring complete replacement. Long-term operation can also cause filter bag shrinkage, installation failure, and flue gas short circuit, increasing equipment maintenance costs and downtime risks. Therefore, this invention proposes an acid and alkali resistant paint booth composite structure dust collector filter bag.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an acid and alkali resistant paint booth composite structure dust collector filter bag, comprising a bag body, a frame, and a cleaning device. The frame is inserted into the inner wall of the bag body, and the cleaning device is located at one end of the frame. The cleaning device includes a protective ring, which is fixedly connected to the frame. A retaining seat is fixedly connected to the upper surface of the protective ring, and a hanging rod is rotatably connected to the upper surface of the retaining seat. An outer frame is fixedly connected to the upper surface of the bag body, and the hanging rod is engaged with the outer frame. An assembly plate is fixedly connected to the inner wall of the frame, and a servo motor is fixedly connected to the surface of the assembly plate. The drive end of the servo motor passes through the assembly plate and is fixedly connected to a rotating rod. A scraper is fixedly connected to the surface of the rotating rod. By setting up the cleaning device, the servo motor drives the rotating rod to rotate the scraper, which can efficiently scrape off adhering impurities along the inner wall of the bag. The hanging rod can rotate and detach from the outer frame, facilitating the removal of the frame and the disassembly of the bag, realizing mechanized active dust removal, improving cleaning efficiency and maintenance convenience.

[0006] Preferably, there are multiple scrapers arranged in a linear array along the rotating rod. By setting the scrapers, the servo motor drives the rotating rod to rotate along the inner wall of the filter bag, which can forcefully scrape off the dust, wet and sticky impurities adhering to the inner wall of the filter bag, thus solving the problem of filter bag clogging and increased resistance caused by dust accumulation.

[0007] Preferably, the longitudinal section of the hanging rod is L-shaped, the diameter of the scraper is the same as the inner diameter of the bag body, and the scraper is located in the inner wall of the bag body. By setting the hanging rod, the frame is fixed inside the bag, ensuring that the frame will not shake or shift when the scraper rotates to clean, and ensuring that the scraper can stably rotate along the inner wall of the bag to scrape away impurities. At the same time, when the bag needs to be maintained or replaced, the frame can be easily pulled out of the bag by rotating the hanging rod to detach it from the outer frame, realizing the quick disassembly and installation of the filter bag assembly and improving the equipment maintenance efficiency.

[0008] Preferably, a torsion spring is fitted on the surface of the hanging rod, and the two ends of the torsion spring are fixedly connected to the card seat and the hanging rod respectively. By setting the torsion spring, when the hanging rod is rotated to disengage from the outer frame, the torsion spring provides a reverse restoring torque through elastic deformation, ensuring that the hanging rod is stably fixed to the outer frame in the installed state and preventing it from loosening due to vibration or other factors.

[0009] Preferably, the surface of the protective ring is provided with a tapping component, which includes a DC motor. The DC motor is fixedly connected to the protective ring, and a rocker arm is fixedly connected to the drive end of the DC motor. By setting the tapping component, the DC motor drives the rocker arm to drive the connecting rod to tap the filter bag, which can assist the scraper to vibrate and loosen stubborn dust, especially for sticky or clump impurities, enhance the dust removal effect, and reduce residue. The combination of the two can cover the dual effects of scraping and vibration, optimize the cleanliness of the inner wall of the filter bag, reduce the frequency of manual intervention, and extend the service life of the filter bag.

[0010] Preferably, a connecting rod is fixedly connected to the surface of the rocker arm, and the connecting rod is in contact with the bag body.

[0011] Preferably, there are multiple connecting rods arranged in a linear array along the rocker arm. By setting the connecting rods, the connecting rods play a key role in converting the circular motion of the rocker arm into a reciprocating striking motion in the striking assembly. When the DC motor drives the rocker arm to make circular motion, the end point of the rocker arm is hinged to the connecting rod, which drives the connecting rod to make a striking motion.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a cleaning device, when it is necessary to clean the inside of the cloth bag, the servo motor is started. The servo motor drives the rotating rod to rotate the scraper. The scraper rotates along the inner wall of the cloth bag, scraping off the impurities adhering to the inner wall of the cloth bag. When it is necessary to remove the cloth bag, the hanging rod is rotated, and the hanging rod is detached from the outer frame. At this time, the frame can be pulled out of the cloth bag. By setting up a cleaning device, the servo motor drives the rotating rod to rotate the scraper, which can efficiently scrape off the adhering impurities along the inner wall of the cloth bag. Moreover, the hanging rod can rotate to detach from the outer frame, which is convenient for the frame to be pulled out and the cloth bag to be disassembled, realizing mechanized active dust removal, improving cleaning efficiency and maintenance convenience.

[0014] 2. In this utility model, by setting up a tapping component, when the scraper scrapes and cleans the inner wall of the filter bag, the DC motor is started. The DC motor drives the rocker arm to rotate, and while the rocker arm rotates, it drives the connecting rod to continuously tap the filter bag, assisting the scraper in cleaning the inside of the filter bag. By setting up the tapping component, the DC motor drives the rocker arm to drive the connecting rod to tap the filter bag, which can assist the scraper in vibrating and loosening stubborn dust, especially for sticky or clump impurities, enhancing the dust removal effect and reducing residue. The combination of the two can cover the dual effects of scraping and vibration, optimize the cleanliness of the inner wall of the filter bag, reduce the frequency of manual intervention, and extend the service life of the filter bag.

[0021] Please see Figures 1-5 This utility model provides a technical solution: an acid and alkali resistant paint booth composite structure dust removal filter bag, including a bag body 1, a frame 2 and a cleaning device 3, the frame 2 is inserted into the inner wall of the bag body 1, and the cleaning device 3 is set at one end of the frame 2.

[0022] In this implementation scheme: the cleaning device 3 includes a protective ring 35, which is fixedly connected to the frame 2. A card holder 38 is fixedly connected to the upper surface of the protective ring 35, and a hanging rod 36 is rotatably connected to the upper surface of the card holder 38. An outer frame 310 is fixedly connected to the upper surface of the bag body 1, and the hanging rod 36 is engaged with the outer frame 310. An assembly plate 31 is fixedly connected to the inner wall of the frame 2. A servo motor 32 is fixedly connected to the surface of the assembly plate 31. The drive end of the servo motor 32 passes through the assembly plate 31 and is fixedly connected to a rotating rod 33. A scraper 34 is fixedly connected to the surface of the rotating rod 33. By setting up the cleaning device 3, the servo motor 32 drives the rotating rod 33 to rotate the scraper 34, which can efficiently scrape off the adhering impurities along the inner wall of the bag. The hanging rod 36 can rotate and detach from the outer frame 310, which facilitates the removal of the frame 2 and the disassembly of the bag, realizing mechanized active dust removal and improving cleaning efficiency and maintenance convenience.

[0023] Specifically, there are multiple scraper blades 34, which are arranged in a linear array along the rotating rod 33. By setting up the scraper blades 34, the servo motor 32 drives the rotating rod 33 to rotate along the inner wall of the filter bag, which can forcefully scrape off the dust, wet and sticky impurities adhering to the inner wall of the filter bag, thus solving the problem of filter bag clogging and increased resistance caused by dust accumulation.

[0024] Specifically, the longitudinal section of the hanging rod 36 is L-shaped, and the diameter of the scraper 34 is the same as the inner diameter of the bag body 1. The scraper 34 is located in the inner wall of the filter bag. By setting the hanging rod 36, the frame 2 is fixed inside the filter bag, ensuring that the frame 2 will not shake or shift when the scraper 34 rotates for cleaning. This ensures that the scraper 34 can stably rotate along the inner wall of the filter bag to scrape away impurities. At the same time, when the filter bag needs to be maintained or replaced, the frame 2 can be easily pulled out of the filter bag by rotating the hanging rod 36 to detach it from the outer frame 310, realizing the quick disassembly and installation of the filter bag assembly and improving the equipment maintenance efficiency.

[0025] Specifically, a torsion spring 37 is fitted on the surface of the hanging rod 36. The two ends of the torsion spring 37 are fixedly connected to the card seat 38 and the hanging rod 36 respectively. By setting the torsion spring 37, when the hanging rod 36 is rotated to disengage from the outer frame 310, the torsion spring 37 provides a reverse restoring torque through elastic deformation, ensuring that the hanging rod 36 is stably fixed to the outer frame 310 in the installed state and preventing it from loosening due to vibration or other factors.

[0026] Specifically, the surface of the retaining ring 35 is provided with a flapping component 39, which includes a DC motor 391. The DC motor 391 is fixedly connected to the retaining ring 35, and a rocker arm 392 is fixedly connected to the drive end of the DC motor 391.

[0027] In this embodiment: by setting up the patting component 39, the DC motor 391 drives the rocker arm 392 to drive the connecting rod 393 to pat the filter bag, which can assist the scraper 34 in vibrating and loosening stubborn dust, especially for sticky or clump impurities, enhance the dust removal effect, reduce residue, and the combination of the two can cover the dual effects of scraping and vibration, optimize the cleanliness of the inner wall of the filter bag, reduce the frequency of manual intervention, and extend the service life of the filter bag.

[0028] Specifically, a connecting rod 393 is fixedly connected to the surface of the rocker arm 392, and the connecting rod 393 contacts the bag body 1.

[0029] Specifically, there are multiple links 393, which are arranged in a linear array along the rocker arm 392.

[0030] In this embodiment: By setting the connecting rod 393, the connecting rod 393 plays a key role in the tapping assembly 39 in converting the circular motion of the rocker arm 392 into a reciprocating tapping action. When the DC motor 391 drives the rocker arm 392 to make circular motion, the end point of the rocker arm 392 is hinged to the connecting rod 393, thereby driving the connecting rod 393 to make a tapping motion.

[0031] Working principle: By setting up the cleaning device 3, when it is necessary to clean the inside of the bag, the servo motor 32 is started. The servo motor 32 drives the rotating rod 33 to rotate the scraper 34. The scraper 34 rotates along the inner wall of the bag and scrapes off the impurities adhering to the inner wall of the bag. When it is necessary to remove the bag, the hanging rod 36 is rotated and the hanging rod 36 is disengaged from the outer frame 310. At this time, the frame 2 can be pulled out of the bag. By setting up the cleaning device 3, the servo motor 32 drives the rotating rod 33 to rotate the scraper 34, which can efficiently scrape off the adhering impurities along the inner wall of the bag. The hanging rod 36 can rotate and disengage from the outer frame 310, which is convenient for the frame 2 to be pulled out and the bag to be disassembled, realizing mechanized active dust removal and improving cleaning efficiency and maintenance convenience.

[0032] By setting up the tapping component 39, when the scraper 34 is scraping and cleaning the inner wall of the filter bag, the DC motor 391 is started. The DC motor 391 drives the rocker arm 392 to rotate. While the rocker arm 392 is rotating, it drives the connecting rod 393 to continuously tap the filter bag, assisting the scraper 34 in cleaning the inside of the filter bag. By setting up the tapping component, the DC motor 391 drives the rocker arm 392 to drive the connecting rod 393 to tap the filter bag, which can assist the scraper 34 in vibrating and loosening stubborn dust, especially for sticky or clump impurities, enhancing the dust removal effect and reducing residue. The combination of the two can cover the dual effects of scraping and vibration, optimize the cleanliness of the inner wall of the filter bag, reduce the frequency of manual intervention, and extend the service life of the filter bag.
