Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle screening, and in particular relates to a multifunctional filtering device. Background Art

[0002] Plastic particle raw materials are mixed with large-diameter impurities and metal debris. The large-diameter impurities in the raw materials can be screened by a vibrating screen. However, due to the small diameter of the metal raw materials, they will pass through the sieve holes with the raw materials. When the magnetic device installed on the current filter device adsorbs the metal debris, the raw materials will pass through the surface of the magnetic device. After the metal debris is adsorbed by the magnetic device, the subsequent raw materials will still contact the magnetic device and the adsorbed metal debris. The subsequent raw materials will squeeze the adsorbed metal debris, causing the metal debris to fall off the magnetic device. In addition, during the adsorption process, the raw materials and metal debris are densely distributed. The raw materials will affect the adsorption of the metal debris by the magnetic device, and affect the screening effect of the magnetic device on the metal debris. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A multifunctional filtering device, including a plastic particle vibration screening machine 1, a circulating conveyor belt 2 is installed on the inner wall of the plastic particle vibration screening machine 1, a plurality of uniformly distributed magnetic adsorption and screening strips 21 are fixedly connected to the outer wall of the circulating conveyor belt 2, an isolation film 22 is fixedly connected to the outer walls of the plurality of magnetic adsorption and screening strips 21, an iron filings scraper 23 is installed at the top of the isolation film 22, the iron filings scraper 23 is fixedly connected to the plastic particle vibration screening machine 1, a support frame 3 is fixedly connected to the inner wall of the plastic particle vibration screening machine 1, and an elastic support piece 31 is fixedly connected to the inner wall of the top of the support frame 3.

[0017] In this embodiment: the screen plate of the plastic particle vibration screening machine 1 itself has a certain inclination angle, the staff adds the raw material into the plastic particle vibration screening machine 1 through the feed port, and the raw material moves toward the tail under the inclination angle of the plastic particle vibration screening machine 1 itself and the vibration of the plastic particle vibration screening machine 1, and is limited and flattened by the feed flattening plate 13 when passing through the feed flattening plate 13, and the raw material mixed with metal debris is adsorbed by the magnetic screen bar 21 when passing through the circulating conveyor belt 2 and the magnetic screen bar 21, and the metal debris adheres to the surface of the isolation film 22 and moves with the isolation film 22 until it moves to the position of the iron chip scraper 23, and is scraped to the edge position by the iron chip scraper 23 and then falls downward, and the magnetic screen bars 21 are distributed at intervals, and the gap position between the metal debris adhered to the isolation film 22 and the magnetic screen bar 21 is aligned. At this time, the magnetic screening bar 21 can no longer continue to absorb the metal debris, so that the metal debris can smoothly fall on the guide inclined plate 12 and slide downward at the inclined angle of the guide inclined plate 12. The raw material after the metal debris is screened continues to move backward until it moves to the sieve hole position, and the raw material that meets the composite requirements falls downward, and the remaining impurities remain on the sieve plate. The raw material and impurities are discharged from the corresponding discharge ports respectively. The support frame 3 and the elastic support sheet 31 themselves have greater elasticity. Under the vibration action of the plastic particle vibration screening machine 1, they oscillate greatly, increasing the vibration amplitude of the raw material, so that the metal debris can be closer to the magnetic screening bar 21, so that the magnetic screening bar 21 can fully absorb the metal debris, thereby improving the screening effect of the circulating conveyor belt 2 and the magnetic screening bar 21 on the metal debris in the raw material.

[0018] A clearance gap 11 is provided on the side wall of the plastic particle vibration screening machine 1, and a guide inclined plate 12 is fixedly connected to the inner wall of the clearance gap 11, and the top of the guide inclined plate 12 extends into the circulating conveyor belt 2; the clearance gap 11 is provided to make way for the guide inclined plate 12, and an installation space is provided for the guide inclined plate 12, so that the top of the guide inclined plate 12 can extend into the circulating conveyor belt 2, so that the guide inclined plate 12 can completely gather and guide the fallen metal materials, so that the metal debris can fall to the outside of the equipment, and the metal debris is prevented from falling into the raw material again.

[0019] A feed spreading plate 13 is fixedly connected to the inner wall of the plastic particle vibration screening machine 1, and a gap is left between the feed spreading plate 13 and the bottom plate of the plastic particle vibration screening machine 1; the feed spreading plate 13 is arranged at the front end of the screen plate of the plastic particle vibration screening machine 1, and the unscreened raw materials move backwards through the gap, so as to spread the added raw materials to reduce the thickness of the raw materials spread on the screen plate, thereby preventing the metal raw materials located below from being pressed by the raw materials located above and unable to be magnetically adsorbed by the magnetic screening bars 21.

[0020] Below the elastic support piece 31, there is a driving shaft rod 32, and a top contact cam 33 is fixedly connected to the outer wall of the driving shaft rod 32; the driving shaft rod 32 is connected to a driving device, and the driving device drives the driving shaft rod 32 to rotate, so as to drive the top contact cam 33 to rotate. The convex point of the top contact cam 33 intermittently contacts the support plate 34. By setting the cooperation of the driving shaft rod 32 and the top contact cam 33, the elastic support piece 31 can be driven to move, further increasing the oscillation amplitude of the elastic support piece 31, so as to drive the metal debris to move and reduce the distance between the metal debris and the magnetic adsorption and screening strip 21.

[0021] The bottom end of the elastic support piece 31 is fixedly connected with a support plate 34, and the support plate 34 is located above the top contact cam 33; by setting the cooperation of the support plate 34 and the top contact cam 33, the elastic support piece 31 can be touched with a larger area, and the raw materials and metal debris can be oscillated in a larger range.

[0022] The working principle and usage process of the present utility model: The staff adds raw materials into the plastic particle vibration screening machine 1 through the feeding port, and the raw materials move towards the tail under the action of the self-inclination angle of the plastic particle vibration screening machine 1 and the vibration of the plastic particle vibration screening machine 1. When passing through the feeding flat plate 13, they are limited and laid flat by the feeding flat plate 13. When the raw materials doped with metal debris pass through the circulating conveyor belt 2 and the magnetic adsorption and screening strip 21, they are adsorbed by the magnetic adsorption and screening strip 21. The metal debris adheres to the surface of the isolation film 22 and moves with the isolation film 22 until it reaches the position of the iron scrap scraper 23, and is scraped to the edge position by the iron scrap scraper 23 and then falls downward. Moreover, the magnetic adsorption and screening strips 21 are distributed at intervals. When the gap position between the metal debris adhering to the isolation film 22 and the magnetic adsorption and screening strip 21 corresponds, the magnetic adsorption and screening strip 21 can no longer adsorb the metal debris, so that the metal debris can smoothly fall on the guiding inclined plate 12. When the raw materials move to the position corresponding to the support frame 3, the driving device drives the driving shaft rod 32 to rotate, so as to drive the top contact cam 33 to rotate. The convex point of the top contact cam 33 intermittently contacts the support plate 34, driving the elastic support piece 31 to move, further increasing the oscillation amplitude of the elastic support piece 31, so as to drive the metal debris to move and reduce the distance between the metal debris and the magnetic adsorption and screening strip 21, enabling the magnetic adsorption and screening strip 21 to more effectively adsorb the metal debris doped in the raw materials.
