Description

Technical Field

[0001] This utility model relates to the field of paint pipeline circulation filtration technology, specifically a paint pipeline circulation filtration system with self-cleaning function. Background Technology

[0002] In industrial production, coatings are widely used in automobile manufacturing, furniture coating, building decoration, electronic device casing spraying and other fields. The coating pipeline circulation system is a core component of the coating process. Its function is to ensure that the coating remains uniform, stable and clean during transportation, and to avoid affecting the coating quality due to impurities.

[0003] A search of Chinese patent CN218686930U reveals a solar heating pipe circulation filter, comprising a filter body, a partition at the bottom of the filter body, an extension tube at the top of the partition, a fixed cover at the top of the filter body, a filter screen at the center of the bottom of the fixed cover, movable rods penetrating through both ends of the fixed cover, and limit springs on the outside of the movable rods. An insertion rod is located at the end of the movable rod near the center point inside the fixed cover, and a handle is located at the center of the top of the fixed cover, with a frosted sleeve on the outside of the handle. This utility model, by comprising a fixed cover, movable rods, a filter body, a filter screen, limit springs, and insertion rods, allows the insertion rod to be moved out of the filter body by moving the movable rod, thereby enabling quick removal and cleaning / replacement of the filter screen.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The gel substances produced after the high solid content components or solvents in the coating evaporate will gradually deposit on the surface or internal pores of the filter, resulting in a decrease in filtration efficiency. Frequent clogging not only increases the frequency of manual cleaning, but may also cause problems such as pump overload and coating delivery interruption, which seriously affects the stability of continuous production.

[0027] In this embodiment of the utility model, the connecting pipe 2 is connected to an external coating conveying device, the circulation pipe 3 is connected to an external coating spraying device, and the drainage pipe 16 is connected to an external processing device. The operator controls the external coating conveying device to transport the coating to the inside of the machine body 1, so that the coating flows into the inside of the filter cylinder 8 for filtration. The filtered coating flows through the circulation pipe 3 to the external coating spraying device for spraying. The filtered impurities are washed with water during cleaning and flow into the external processing device through the drainage pipe 16.

[0028] Figures 1 to 5 As shown, the filtration mechanism includes a support assembly disposed on the inner wall of the body 1, a filter cylinder 8 disposed on the support assembly, an installation assembly disposed on the filter cylinder 8, a movable cover 11 rotatably connected to the end of the connecting pipe 2 disposed on the installation assembly, and a drive assembly disposed between the body 1 and the movable cover 11. The support assembly includes a bottom ring 5 fixedly installed on the inner side of the inner wall of the body 1, and a plurality of recesses 6 are provided on the bottom ring 5. A plurality of support rods 7 that engage with the recesses 6 are fixedly installed on the bottom of the filter cylinder 8. The installation assembly includes a plurality of insert shells 9 fixedly installed on the filter cylinder 8. An insert plate 10 fixed to the movable cover 11 is slidably installed on each insert shell 9. A gear ring 12 is fixedly installed on the movable cover 11. The drive assembly includes a drive motor 13 fixedly disposed on the cover body 4. A transmission rod 14 rotatably connected to the cover body 4 is fixedly installed on the output end of the drive motor 13. A gear 15 that meshes with the gear ring 12 is fixedly installed on the transmission rod 14.

[0029] In this embodiment of the utility model, the operator controls the drive motor 13 to operate, causing the output end of the drive motor 13 to rotate, which in turn drives the gear 15 to rotate via the transmission rod 14. The rotation of the gear 15 drives the gear ring 12 to rotate, which in turn drives the filter cylinder 8 to rotate via the movable cover 11, the insert plate 10, and the insert shell 9. The centrifugal force of the rotation, combined with the water, can clean the impurities accumulated in the filter cylinder 8. The rotation of the filter cylinder 8 causes multiple support rods 7 to engage with multiple concave holes 6, allowing the filter cylinder 8 to move up and down, thereby further improving the ability to clean impurities. The impurities flow with the water through the drainage pipe 16 to the external treatment equipment.

[0030] Figures 1 to 5 As shown, a rinsing mechanism is provided on the body 1. The rinsing mechanism includes an electric telescopic rod 17 fixedly mounted on the body 1.

The conveying component includes an interface 23 fixedly mounted on the cover 4. A hose 22 is connected between the annular shell 20 and the interface 23.

[0031] In this embodiment of the utility model, the operator controls the telescopic end of the electric telescopic rod 17 to move it, so that the telescopic end of the electric telescopic rod drives the ring shell 20 to move between the machine body 1 and the filter cylinder 8 through the connecting plate 18 and the long rod 19. At the same time, the operator controls the external water conveying equipment to deliver water to the inside of the ring shell 20 through the interface 23 and the hose 22, and sprays it out from the nozzle 21 to perform water rinsing work on the filter cylinder 8, thereby improving the water rinsing ability.

[0032] Working principle: The operator controls the external coating conveying equipment to deliver the coating to the inside of the machine body 1, so that the coating flows into the inside of the filter cylinder 8 for filtration. The filtered coating flows through the circulation pipe 3 to the external coating spraying equipment for spraying. The filtered impurities are washed with water during the cleaning process and flow into the external treatment equipment through the drainage pipe 16.

[0033] When the filter cartridge 8 needs to be self-cleaned, the drive motor 13 is operated by controlling the gear 15 to rotate the gear ring 12. The gear ring 12 drives the filter cartridge 8 to rotate through the movable cover 11, the insert plate 10 and the insert shell 9. The rotation, together with the water, cleans the impurities accumulated inside the filter cartridge 8. The rotation of the filter cartridge 8 drives multiple support rods 7 to engage with multiple concave holes 6, causing the filter cartridge 8 to move up and down. The impurities flow with the water through the drainage pipe 16 to the external treatment equipment. The extension end of the electric telescopic rod 17 is moved by controlling the extension end of the electric telescopic rod. The extension end of the electric telescopic rod drives the ring shell 20 to move between the machine body 1 and the filter cartridge 8 through the connecting plate 18 and the long rod 19. At the same time, the external water delivery equipment is controlled to deliver water to the inside of the ring shell 20 through the interface 23 and the hose 22, and spray it out from the nozzle 21 to rinse the filter cartridge 8.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
