Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for impurities in plastic particle raw materials. Background Art

[0002] Plastic particle raw materials refer to the basic materials used to manufacture plastic products, usually in granular or powdered form. These raw materials are usually composed of polymers and additives. The selection of plastic particle raw materials depends on factors such as the performance requirements of the required products, processing technology and cost considerations. Often, there are many impurities inside the production, which need to be filtered. The filtration device for impurities in plastic particle raw materials is a device used to remove impurities from plastic particle raw materials. It usually consists of a filter, a feed port, a discharge port and a filter screen. During operation, the plastic particle raw materials containing impurities are input into the device through the feed port. Through the action of the filter screen, the impurities are blocked on the filter screen, and the pure plastic particles flow out through the discharge port. The filtration device can use different filter screen materials and apertures to adapt to impurities of different types and sizes. This device can be widely used in the plastic processing industry to improve the quality and reliability of plastic products;

[0003] After searching, the Chinese patent with the announcement number: CN219543747U discloses a filtering device for removing metal impurities from engineering plastic particles. The patent records that the flow rate of engineering plastic particles contained in the material trough falling into the machine body can be controlled by setting a sliding plate; the baffle can be shaken by a cam set in the shaking mechanism, so that the metal impurities in the engineering plastic particles above the screen are screened off.

[0004] In this solution, since the plastic particles contain more impurities, and when filtering through the screen, it is inevitable that some larger impurities will get stuck in the holes of the screen, resulting in a slower filtration time probability, or the staff needs to clean the blocked impurities by hand, and this process requires stopping the equipment for cleaning, resulting in a significant reduction in filtration efficiency. In order to solve this technical problem, the utility model proposes a filtering device for impurities in plastic particle raw materials. Summary of the invention

One end of the inner rod 11 is fixedly connected to a pulley 12, and the outer wall of one end of the bidirectional threaded rod 15 is fixedly connected to a pulley 2 14, and a belt 13 is arranged between the pulley 2 14 and the pulley 1 12. At the same time, the connecting column 17 is threadedly connected to the outer walls at both ends of the bidirectional threaded rod 15, and brush plates 19 are arranged at the bottom of the connecting columns 17 on both sides. The brush plates 19 are fixedly connected to the connecting columns 17 by screws 18, and the brush plates 19 are tightly attached to the outer wall of the filter cartridge 7. The top of the bracket 10 is fixedly connected to a fixing plate 16, and the bidirectional threaded rod 15 is rotatably connected to the inside of the fixing plate 16. A pair of slide grooves 20 are opened at the top of the bracket 10, and the connecting column 17 corresponds to the slide groove 20, and the connecting column 17 is slidably connected in the slide groove 20.

[0025] After the motor 2 is started, its rotation drives the rotating rod 4 to rotate, and then drives the gears 5 at both ends to rotate. The rotation of the gear 5 drives the gear ring 9 and the filter cartridge 7 to rotate. The filter cartridge 7 is limited to rotate in the bracket 10 by the inner rod 11, and is limited to be positioned on the roller 6 by the guide rail 8. When the inner rod 11 rotates, the pulley 12 at the other end rotates, and drives the pulley 2 14 to rotate through the belt 13. The rotation of the pulley 2 14 drives the bidirectional threaded rod 15 to rotate inside the fixed plate 16. The rotation of the bidirectional threaded rod 15 causes the connecting columns 17 at both ends to move in the opposite direction, so that the connecting column 17 brushes back and forth on the surface of the filter cartridge 7 to remove impurities that block the leak hole. The movement of the connecting column 17 is limited in the chute 20 to ensure that it maintains its direction when moving. By removing the screw 18, the brush plate 19 on the connecting column 17 can be easily replaced, saving time and effort.

[0026] During operation, when the staff needs to filter impurities in the plastic particle raw material, first pour the plastic particle raw material into the filter cartridge 7, then start the motor 2, and drive the rotating rod 4 to rotate under the action of the motor 2. When the rotating rod 4 rotates, it will drive the gears 5 at both ends to rotate, and the rotation of the gear 5 will drive the gear ring 9 and the filter cartridge 7 to rotate. At the same time, the filter cartridge 7 is limited to rotate in the bracket 10 by the inner rod 11. At the same time, the filter cartridge 7 is limited on the roller 6 by the guide rail 8 for positioning. When the inner rod 11 rotates, it will drive the pulley 1 12 at the other end to rotate. At this time, the pulley 2 14 is driven by the belt 13 to rotate. The two-way threaded rod 15 rotates and drives the two-way threaded rod 15 to rotate inside the fixed plate 16. The rotation of the two-way threaded rod 15 drives the connecting posts 17 at both ends to move in the opposite direction. At this time, the connecting posts 17 brush back and forth on the surface of the filter cartridge 7 through the rotation of the two-way threaded rod 15, and impurities are placed to block the leakage holes in the filter cartridge 7. When the connecting posts 17 move, they are limited in the slide groove 20, so that the connecting posts 17 maintain the direction of movement when moving. At the same time, by pulling out the screws 18, the brush plate 19 can be removed and replaced from the connecting posts 17, which saves time and effort. Through the cooperation between them, the plastic particle raw materials can filter impurities while brushing the filter cartridge 7, which greatly improves the work efficiency.
