Description

Technical Field

[0001] The utility model relates to the technical field related to plastic particle processing, and more specifically to a plastic particle metal impurity filtering device. Background Art

[0002] Engineering plastics can be used as engineering materials and plastics that replace metals to manufacture machine parts. During the production process of engineering plastic particles, due to production reasons, small metal particles from the production equipment will be mixed into the plastic particles. These metal impurities will directly affect the quality and use of engineering plastic particles, so the metal impurities need to be treated.

[0003] The patent with publication number CN214183575U disclosed a filtering device for removing metal impurities from engineering plastic particles, including a mounting frame, a filter barrel fixedly mounted on the inner side of the mounting frame, and a top cover movably connected to the top of the filter barrel. The filtering device for removing metal impurities from engineering plastic particles uses a dust filter barrel, an isolation net, an adsorption fan, and a storage bin. When plastic particles fall into the inner cavity of the mounting frame, the adsorption fan is used to adsorb dust particles mixed in the plastic particles into the inner cavity of the dust filter barrel, thereby removing dust from the engineering plastic particles, improving the quality of the engineering plastic particles. At the same time, the isolation net can effectively prevent the engineering plastic particles from entering the inner cavity of the dust filter barrel, improving the practicality of the filtering device for removing metal impurities from engineering plastic particles.

[0004] In actual use, the above-mentioned prior art utilizes an electromagnetic rod to adsorb metal impurities. The contact range between the plastic particles and the electromagnetic rod is limited, and some metal impurities cannot contact the electromagnetic rod, resulting in the metal impurities in the plastic particles being discharged without being completely adsorbed. In addition, the metal impurities adsorbed on the electromagnetic rod are difficult to clean and collect. Utility Model Content

The front of the drawer 6 is fixedly provided with an edge B12, and a limiting hole 13 is provided on the edge B12, and the latch 11 can be inserted into the limiting hole 13.

[0029] In this embodiment, preferably, an electric slide rail 14 is fixedly installed on the top of the filter barrel 2, an electric slider 15 is slidably arranged on the top of the electric slide rail 14, a connecting rod 16 is fixedly arranged on one side of the electric slider 15, and a scraper 17 acting on the metal adsorption plate 7 is fixedly arranged on the end of the connecting rod 16 away from the electric slider 15.

[0030] In this embodiment, preferably, a collecting box 18 is fixedly provided on the front of the filter barrel 2 . The collecting box 18 is located directly below the scraper 17 and has a length greater than the stroke of the scraper 17 .

[0031] In this embodiment, preferably, the rotating shaft 3 is a hollow component, and an air pump 19 rotatably connected to the rotating shaft 3 is installed on the right side of the top of the base 1. Evenly distributed air holes 31 are opened on the outer wall of the rotating shaft 3, and a dustproof cloth is arranged in the air holes 31. The dustproof cloth can prevent metal impurities from entering the rotating shaft 3 through the air holes 31.

[0032] In this embodiment, preferably, the spiral separation augers 4 on the outer wall of the rotating shaft 3 are arranged in two groups, the two groups of spiral separation augers 4 are symmetrically arranged and have opposite spiral directions, and a push plate 20 is fixedly connected between the two spiral separation augers 4, and the push plate 20 contacts the inner wall of the filter barrel 2.

[0035] The working principle and use process of this utility model:

[0036] The plastic particles to be removed of metal impurities are put into the feed hopper 21. Since the feed hopper 21 is in the shape of a "human" as a whole and the upper part of the feed hopper 21 is in the shape of a "Y", the plastic particles can slow down the downstream speed when entering the upper part of the feed hopper 21, and be diverted from the middle position, and can be dispersed along the bifurcation position of the feed hopper 21. When the plastic particles enter the filter barrel 2, the motor 5 is started to drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the spiral separation auger 4 to lift the plastic particles and move them toward the discharge pipe 22. In this process, the push plate 20 can push the plastic particles to do an upward throwing motion, and the air pump 19 passes gas into the rotating shaft 3, which is discharged from the air hole 31 and blown toward the plastic particles. The above process is to turn over and stir the plastic particles to make them do irregular motion. The rotation speed of the motor 5 is controllable, so that the plastic particles can move toward the discharge pipe 22 at a relatively low speed, thereby separating the plastic particles from the metal impurities mixed in the plastic particles.

[0037] After the plastic particles and the metal impurities mixed in the plastic particles are separated, the metal impurities separated from the plastic particles are adsorbed away by the metal adsorption plate 7, and the metal impurities are adsorbed on the metal adsorption plate 7, thereby achieving the filtration of the metal impurities in the plastic particles;

[0038] After completing the filtering of the metal impurities in the plastic particles, the latch 11 is pulled out, and the drawer 6 can be pulled out by the cooperation of the slide bar 9 and the inverted convex slide groove 8. After the drawer 6 is completely pulled out, the electric slide rail 14 can be used to drive the electric slider 15 to move, and the electric slider 15 drives the connecting rod 16 to make the scraper 17 "scrape" the metal adsorption plate 7, so that the metal impurities adsorbed on the metal adsorption plate 7 are cleaned off and fall into the collection box 18 for subsequent processing, so as to facilitate the cleaning and collection of the filtered metal impurities.

[0039] The electronic components and modules used in the content of this utility model can all be parts that are commonly used in the market and can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs. The electronic components and modules are all connected to an external power supply and a control switch for use. Their specific circuit connection methods and methods of use are commonly used public technologies and will not be elaborated on here.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
