This wet paint mist filter with a cleaning structure includes a casing, a purification chamber and a dehumidification chamber are arranged on both sides of the casing, a horizontally distributed filter cylinder is arranged in the purification chamber, the rotating shaft on the left side of the mounting plate is connected to the motor through a belt, and the rotating shaft on the right side of the mounting plate is connected to the horizontal axis through a belt, a fan blade is arranged above the inside of the dehumidification chamber, and a refrigeration plate is arranged below the fan blade, a horizontal cylinder is installed on the casing wall between the purification chamber and the dehumidification chamber, and a fan and an electric heating wire are installed inside the horizontal cylinder.

[0004] The device disclosed in this patent can effectively remove filtered waste on the surface of the filter cartridge by using structures such as a cross bar under the rotating shaft. However, when the device is in use, the bristles on the cross bar only prevent clogging of the filter cartridge mesh after cleaning the surface of the filter cartridge. These impurities still accumulate in the filter cartridge, and the impurities in the filter cartridge cannot be effectively cleaned. Therefore, the staff is required to remove the filter cartridge from the equipment before cleaning the impurities in the filter cartridge. This method increases the workload of the staff. At the same time, this operation method requires the wet paint mist filter to stop running before operation can be performed, thereby affecting the normal use of the wet paint mist filter.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4As shown, a purification device for wet paint mist pretreatment includes a shell 1, a water pump 2 is fixedly installed on the upper surface of the shell 1, a circulation pipe 3 is fixedly installed on the input pipe of the water pump 2, the other end of the circulation pipe 3 penetrates into the bottom of the shell 1, the lower end of the output pipe of the water pump 2 penetrates into the shell 1, the lower end of the output pipe of the water pump 2 is fixedly connected with an atomizing nozzle 4, and an air outlet pipe is provided on the back of the shell 1, so that purified liquid at the bottom of the shell 1 is extracted through the circulation pipe 3, and the purified liquid is sprayed through the atomizing nozzle 4, so as to purify the exhaust gas in the shell 1, and the purified gas is discharged through the air outlet pipe.

[0022] Two connecting plates 8 are provided in the shell 1, and the two connecting plates 8 are horizontally arranged. A driving pipe 5 is provided on the outside of the shell 1. A rotating plate 6 is rotatably connected to one end of the driving pipe 5, and an air intake pipe 7 is fixedly connected to the other side surface of the rotating plate 6. The air intake pipe 7 is connected to the driving pipe 5, and the other end of the driving pipe 5 rotates and penetrates into the shell 1. A connecting plate 8 is fixedly sleeved on the outer surface of the driving pipe 5, and a filter cartridge 9 is fixedly connected between the two connecting plates 8. A connecting shaft 10 is fixedly connected to the side of the shell 1 facing away from the driving pipe 5, one end of the connecting shaft 10 penetrates into the shell 1, and the other connecting plate 8 is rotatably sleeved on the outer surface of the connecting shaft 10. Exhaust gas is introduced into the driving pipe 5 through the air intake pipe 7. After entering the filter cartridge 9, the exhaust gas contacts with the sprayed purification liquid, so that the exhaust gas can be purified. At the same time, impurities absorbed by the liquid are blocked by the mesh of the filter cartridge 9, so that these impurities remain in the filter cartridge 9, and the filtered liquid falls into the bottom of the shell 1 again, so that it can be recycled.

[0023] A pulley 16 is fixedly sleeved on the outer surface of one end of the driving tube 5 located outside the shell 1, and a motor 15 is fixedly installed on the side of the shell 1. The output shaft of the motor 15 is also fixedly connected to the pulley 16, and a belt 17 is connected between the two pulleys 16. Therefore, the motor 15 can drive the driving tube 5 to rotate, and the connecting plate 8 and the filter cartridge 9 will rotate synchronously with the driving tube 5.

[0024] A vertical scraper 14 is fixedly connected to the upper surface of the connecting shaft 10 located in the filter cartridge 9. The upper side of the vertical scraper 14 contacts the inner side of the filter cartridge 9. The connecting shaft 10 is provided with a blanking groove 12 extending from the upper and lower surfaces thereof, and the front of the vertical scraper 14 is at the same vertical position as the inner wall of the blanking groove 12. A collecting drawer 11 is provided on the outer side of the connecting shaft 10. One side of the collecting drawer 11 slides through the blanking groove 12 and fits with the inner wall of the blanking groove 12. Since the impurities in the exhaust gas are adsorbed by water droplets and fall onto the filter cartridge 9, these impurities have a certain adsorption property and can be attached to the inner side of the filter cartridge 9. In this way, when the filter cartridge 9 rotates, the vertical scraper 14 can scrape off the impurities adsorbed on the inner side of the filter cartridge 9, and these scraped impurities fall into the collection drawer 11, so that these impurities can be collected. When these impurities need to be cleaned, the staff only needs to pull out the collection drawer 11 to clean these impurities, and there is no need to dismantle the entire filter cartridge 9 for cleaning, which further reduces the work intensity of the staff and improves the use effect of the purification device. At the same time, since the vertical scraper 14 can continuously scrape the inner side of the filter cartridge 9, it is possible to avoid excessive impurities adhering to the filter cartridge 9 and affecting the use effect of the filter cartridge 9.

[0025] More preferably, a sealing rubber pad is provided on the outer surface of the collection drawer 11, which increases the sealing between the collection drawer 11 and the connecting shaft 10 and avoids leakage problems as much as possible.

[0026] More preferably, the bottom wall of the collection drawer 11 is inlaid with a filter 13 extending from its lower surface, so that the filter 13 can filter water droplets, thereby minimizing the situation where excessive water droplets fall into the collection drawer 11 during use, thereby ensuring the collection effect of the collection drawer 11 on impurities.

[0027] A U-shaped seat 18 is fixedly connected to the surface of the side of the vertical scraper 14 facing away from the blanking groove 12, and a rotating plate 19 is rotatably connected to the U-shaped seat 18. A spring 20 is fixedly connected between the side of the rotating plate 19 away from the connecting plate 8 and the vertical scraper 14. The spring 20 forms a supporting effect on the rotating plate 19, so that the initial state of the rotating plate 19 is horizontal. An impact ball 21 is fixedly connected to the side of the rotating plate 19 facing the vertical scraper 14, and the other side of the rotating plate 19 extends out of the outer surface of the vertical scraper 14. An arc-shaped protrusion 22 is fixedly connected to the surface of the side of the connecting plate 8 close to the vertical scraper 14. The rotating plate 19 extends out of one side of the vertical scraper 14 and the arc-shaped protrusion 22 is fixedly connected. The arcuate surface of the protrusion 22 is in contact. When the connecting disk 8 rotates, when the arcuate protrusion 22 contacts the rotating plate 19, it will squeeze the rotating plate 19, causing the rotating plate 19 to rotate clockwise. At this time, the impact ball 21 impacts the vertical scraper 14, and the spring 20 is squeezed and contracted. When the arcuate protrusion 22 does not contact the rotating plate 19, the spring 20 pushes the rotating plate 19 to rotate to the initial position. With the above structure, the impact ball 21 can continuously impact the vertical scraper 14, so that the impurities attached to the vertical scraper 14 slide downward under the vibration force, thereby avoiding a large number of impurities attached to the vertical scraper 14 as much as possible, and further improving the cleaning effect of the impurities.

[0028] Working principle: the air inlet pipe 7 leads the exhaust gas into the driving pipe 5. After entering the filter cartridge 9, the exhaust gas comes into contact with the sprayed purification liquid, thereby purifying the exhaust gas. At the same time, the impurities absorbed by the liquid are blocked by the mesh of the filter cartridge 9. The motor 15 is started, and the two pulleys 16 are driven to rotate the driving pipe 5. Therefore, the connecting plate 8 and the filter cartridge 9 will rotate synchronously with the driving pipe 5. The vertical scraper 14 can scrape off the impurities adsorbed on the inner side of the filter cartridge 9, and these scraped impurities fall into the collection drawer 11, thereby collecting these impurities.
