Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a filter for sealant production. Background Technology

[0002] Sealant production filters primarily refer to devices used in the sealant production process to filter impurities from the air, specifically sealant pipeline air filters. By adding a filtration device to the pipeline system, they effectively remove dust, bacteria, particles, and other impurities from the air, ensuring the quality of the sealant products. Filtering airborne impurities prevents these impurities from entering the sealant product, thus guaranteeing product quality and safety. Sealant production filters are crucial equipment for ensuring both sealant product quality and production efficiency. During sealant production, appropriate filter types should be selected based on actual needs, and regular maintenance and replacement are essential to ensure their normal operation and filtration effectiveness.

[0003] An existing patent (publication number: CN220939418U) discloses a silicone sealant filter. When disassembling and assembling this filter, the middle tube is gripped and the conical tube is rotated so that the port rotates inside the end groove, which enables quick disassembly and assembly of the conical tube. At the same time, the filter screen can also be removed from inside the middle tube for cleaning and replacement, making the filter easy to disassemble and assemble. However, cleaning the filter screen requires disassembling the filter screen, which is very troublesome to use and reduces work efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a filter for sealant production, which effectively solves the problem that the existing filter screen needs to be disassembled when cleaning, which is very troublesome to use and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter for sealant production, comprising a base plate, four support legs fixedly installed on the top of the base plate, a device housing fixedly installed between the tops of the four support legs, a feed pipe fixedly installed at one end of the device housing, a discharge pipe fixedly installed at the other end of the device housing, drain valves fixedly installed on both sides of the bottom of the device housing, a coarse filter screen fixedly installed at one end of the device housing, a fine filter screen fixedly installed at the other end of the device housing, a mounting base fixedly installed on the top of the device housing, a drive motor fixedly installed on one side of the mounting base, a transmission assembly provided at the output end of the drive motor, cleaning brushes tightly attached to the upper part of one side of the coarse and fine filter screens, the transmission assembly being connected to the two cleaning brushes in a transmission manner, and when the drive motor is running, power is output to the two cleaning brushes through the transmission assembly, causing the two cleaning brushes to rotate and clean the coarse and fine filter screens.

[0006] Preferably, the transmission assembly includes a worm gear and a protective cover. The worm gear is fixedly installed at the output end of the drive motor. A positioning plate is rotatably installed at one end of the worm gear. The bottom of the positioning plate is fixedly connected to the top of the device housing. A worm wheel is meshed with the surface of the worm gear. A shaft is fixedly installed at the bottom of the worm wheel. A sealing bushing is rotatably installed at the upper end of the shaft surface. The sealing bushing is fixedly installed in the middle of the top of the device housing. The protective cover is fixedly installed in the middle of the inside of the device housing by a support rod.

[0007] Preferably, the bottom end of the shaft extends into the interior of the protective cover and is fixedly mounted with a first bevel gear. A second sealing bushing is rotatably mounted on the lower end of the shaft surface. The second sealing bushing is fixedly mounted in the middle of the top of the protective cover. A second bevel gear is meshed with one side of the surface of the first bevel gear. A rotating rod is fixedly mounted in the middle of the second bevel gear. A third sealing bushing is fixedly mounted on both ends of the protective cover. The rotating rod is rotatably mounted between the interiors of the two third sealing bushings.

[0008] Preferably, two sealing bushings are rotatably mounted on the surface of the rotating rod. The two sealing bushings are fixedly mounted in the middle of the coarse filter screen and the fine filter screen, respectively. Fixing rings are fixedly mounted on both ends of the rotating rod surface. The upper parts of the two fixing rings are fixedly connected to the bottom of the two cleaning brushes, respectively. Positioning discs are rotatably mounted on both ends of the rotating rod. The two positioning discs are fixedly connected to the inner wall of the device housing through connecting rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator allows the medium to enter through the feed pipe and filters it sequentially through the coarse and fine filter screens. The filtered medium is then discharged through the discharge pipe. When there are too many impurities clogging the coarse and fine filter screens, the operator starts the drive motor to drive the worm gear to rotate along the positioning plate. When the worm gear rotates, it drives the shaft to rotate inside the first and second sealing sleeves through the worm wheel. When the shaft rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the rotating rod to rotate inside the third and fourth sealing sleeves.

[0010] When the rotating rod rotates, it also rotates along the two positioning discs, which improves the stability of the rotating rod during rotation. At the same time, the rotating rod drives the two cleaning brushes through the two fixed rings to rotate and clean the coarse and fine filter screens. The cleaned-off impurities accumulate on the top of the two drain valves. Opening the two drain valves can discharge the impurities. This makes it possible to clean the filter screen without disassembling it, which is very convenient to use and improves work efficiency. Attached Figure Description

[0021] In use, the operator introduces the medium through the feed pipe 4, and the medium is filtered sequentially through the coarse filter screen 7 and the fine filter screen 8. The filtered medium is discharged through the discharge pipe 5. When there is too much impurity clogging the coarse filter screen 7 and the fine filter screen 8, the operator starts the drive motor 10 to drive the transmission component. When the transmission component is running, it drives the two cleaning brushes 25 to rotate and clean the coarse filter screen 7 and the fine filter screen 8. The cleaned impurities accumulate on the top of the two drain valves 6. Opening the two drain valves 6 can discharge the impurities. This makes it convenient to use without disassembling the filter screen when cleaning the filter screen, thus improving work efficiency.

[0022] The transmission assembly includes a worm gear 11 and a protective cover 16. The worm gear 11 is fixedly installed at the output end of the drive motor 10.

The protective cover 16 is fixedly installed in the middle of the inside of the device housing 3 via a support rod 17. The bottom end of the shaft 14 extends into the inside of the protective cover 16 and is fixedly installed with a first bevel gear 19. A second sealing bushing 18 is rotatably installed at the lower end of the surface of the shaft 14. The second sealing bushing 18 is fixedly installed in the protective cover 16. At the top center of the cover 16, a second bevel gear 20 is meshed with one side of the surface of the first bevel gear 19.

The upper parts of the two fixing rings 24 are fixedly connected to the bottom of the two cleaning brushes 25, respectively. Positioning discs 26 are rotatably installed at both ends of the rotating rod 21. The two positioning discs 26 are fixedly connected to the inner wall of the device housing 3 through connecting rods 27.

[0023] When there are too many impurities clogging the coarse filter screen 7 and the fine filter screen 8, the operator starts the drive motor 10 to drive the worm gear 11 to rotate along the positioning plate 12. When the worm gear 11 rotates, it drives the shaft 14 to rotate inside the sealing sleeve 15 and the sealing sleeve 28 through the worm wheel 13.
