Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically to an anti-corrosion coated filter bag. Background Technology

[0002] The primary function of anti-corrosion coating filter bags is to remove impurities, particles, and suspended solids from anti-corrosion coatings, ensuring the purity and stability of the coating and thus improving its quality and coating effect. During the production and application of anti-corrosion coatings, the coating is easily contaminated by external factors such as dust, sand, and fibers. These impurities can affect the coating's performance and coating effect. Anti-corrosion coating filter bags effectively remove these impurities through their filtration function, ensuring the purity of the coating and the quality of the coating. Anti-corrosion coating filter bags are widely used in various fields requiring anti-corrosion coating, such as automobile manufacturing, shipbuilding, and steel structure manufacturing. In automobile manufacturing, anti-corrosion coating filter bags are used to filter particulate matter and microparticles generated during the coating process, ensuring the quality and surface smoothness of the painted automotive products. In shipbuilding and steel structure manufacturing, anti-corrosion coating filter bags also play a crucial role in ensuring the quality and corrosion resistance of the coated products.

[0003] Existing Chinese patent application CN202321849743.7 discloses an anti-corrosion coating filter bag. The existing device has an outer protective cloth connected to the lower end of a first fixing ring, and a filter mesh connected to the lower end of the outer protective cloth. The inner side of the first fixing ring has several spaced locking blocks, and a second fixing ring is connected to the inner side of each locking block. The lower end of the second fixing ring is connected to the filter bag, and a second traction rope is wound around the outer side of the second fixing ring. This device is reasonably designed. In this anti-corrosion coating filter bag, the anti-corrosion coating enters the filter bag, is filtered, and then flows out through the filter mesh. During this process, because the outer protective cloth has no perforations, the anti-corrosion coating will not appear on the outside of the outer protective cloth, preventing workers from being contaminated with the anti-corrosion coating. The double-layer filtration structure also ensures filtration quality. However, the existing device does not consider that both layers of filter mesh are made of flexible material, which can easily cause the two filter meshes to stick together, forming a single filter mesh, reducing filtration quality. Furthermore, the filter mesh pores are prone to clogging and are difficult to clean.

[0004] Therefore, we propose an anti-corrosion coated filter bag to solve the problems mentioned above. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: an anti-corrosion coating filter bag, including a fixing ring 1, a first filter screen 2 installed on the inner ring of the lower end of the fixing ring 1, and a second filter screen 3 installed on the outer ring of the lower end of the fixing ring 1. A motor 4 is installed on the lower left side of the inner side of the fixing ring 1, and a gear 5 is connected to the lower end of the motor 4. A gear ring 6 is sleeved on the gear 5, and a brush plate 7 is installed at the lower end of the gear ring 6. An annular groove 8 is opened at the lower end of the fixing ring 1, and a spherical block 9 is arranged in the annular groove 8. The fixing ring 1 is fixedly connected to the first filter screen 2 and the second filter screen 3, and the second filter screen 3 is arranged around the first filter screen 2. The gear 5 is meshed with the gear ring 6, and the gear ring 6 is... The gear 6 is fixedly connected to the brush plate 7. The upper end of the gear ring 6 is fixedly connected to the spherical block 9, and the annular groove 8 is slidably connected to the spherical block 9. The motor 4 drives the gear 5 to rotate. The gear 5 meshes with the gear ring 6, causing the gear ring 6 to rotate. Because the upper end of the gear ring 6 is provided with the spherical block 9, and the lower end of the fixing ring 1 is provided with the annular groove 8, the spherical block 9 and the annular groove 8 are slidably connected, thus satisfying the rotation of the gear ring 6. The rotation of the gear ring 6 drives the lower brush plate 7 to rotate, separating and cleaning the first filter screen 2 and the second filter screen 3, preventing the two sets of filter screens from sticking together to form a single filter screen, which would reduce the filtration quality of the device. At the same time, the filter holes on the filter screen are prone to clogging, reducing the filtration efficiency of the device and shortening the service life of the device.

[0032] A water storage tank 10 is installed inside the right end of the fixed ring 1, and a water pump 11 is connected to the left end of the water storage tank 10 through a water pipe. The water pump 11 is connected to the gap between the first filter screen 2 and the second filter screen 3 through the water pipe. The water pump 11 delivers water from the water storage tank 10 to the gap between the first filter screen 2 and the second filter screen 3, using water to clean the filter screens, improving the cleaning quality of the device, and cleaning and maintaining the device can extend the service life of the device and save costs.

[0033] The fixed ring 1 has symmetrical cavities 12 at both ends, and a positioning rod 13 is slidably connected inside the cavity 12. The near end of the positioning rod 13 is embedded in the upper end of the second filter screen 3, and the opposite end of the positioning rod 13 is slidably connected to a fixing rod 14. The near end of the positioning rod 13 is fixedly connected to a connecting rod 15. A spring 16 is provided in the middle of the positioning rod 13, and the opposite end of the spring 16 is fixedly connected to the fixing rod 14, and the near end of the spring 16 is fixedly connected to the connecting rod 15. By pulling the positioning rod 13 out to the left and right ends, the positioning rod 13 drives the connecting rod 15 to move to the left and right ends. The fixing rod 14 and the connecting rod 15 compress the spring 16. When the positioning rod 13 is pulled out from the upper end of the second filter screen 3, the second filter screen 3 can be replaced, which plays a maintenance role in the device and improves the filtration efficiency of the device. When the positioning rod 13 is released, the spring 16 drives the connecting rod 15 and the positioning rod 13 to reset, and the second filter screen 3 is fixed again, which increases the convenience of disassembling and installing the second filter screen 3 and saves time.

[0034] Working principle: When using this anti-corrosion coating filter bag, the anti-corrosion coating is poured in through the middle of the fixing ring 1. The first filter screen 2 and the second filter screen 3 filter the anti-corrosion coating. The motor 4 drives the gear 5 to rotate, and the gear 5 drives the gear ring 6 to slide along the annular groove 8. At the same time, the gear ring 6 drives the brush plate 7 to clean the first filter screen 2 and the second filter screen 3 and separate the first filter screen 2 and the second filter screen 3 that are easy to stick together. The water pump 11 delivers water from the water storage tank 10 to the gap between the first filter screen 2 and the second filter screen 3 to enhance the cleaning of the filter screens. The positioning rod 13 is pulled out to both ends. When the positioning rod 13 is pulled out from the upper end of the second filter screen 3, the second filter screen 3 can be replaced, which facilitates the maintenance of the device. Loosening the positioning rod 13 causes the spring 16 to drive the positioning rod 13 to reset, and the second filter screen 3 is fixed again, which improves the convenience of the device.
