Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic particle impurity removal devices, specifically a plastic particle impurity removal device. Background Technology
[0002] The recycling of waste plastic bottles includes steps such as cleaning, disinfection, sorting, crushing, purification, rinsing, and drying, and finally regeneration into high-quality fibers. Impurities in plastic granules, such as metal fragments, dust, particles or residues of other types of plastics, can negatively affect the performance and quality of the final product. By removing impurities, the purity of plastic granules can be ensured, thereby improving the strength and durability of the final plastic products.
[0003] During the processing of plastic granules, impurities such as iron filings inevitably get mixed in. These ferromagnetic impurities, along with the plastic granules, enter the heating zone of the extruder for heating. However, the melting point of ferromagnetic substances is much higher than that of plastic, resulting in the presence of ferromagnetic substances in the resulting solution. This can seriously affect the quality of the product. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-3 The present invention provides a technical solution: a plastic particle impurity removal device, including a machine base 1, a frame 2 vertically installed on the top of the machine base 1, and a horizontal movement component provided on the frame 2, a first receiving tank 12 installed on the top of the machine base 1, a dust cover 8 provided above the machine base 1, and an impurity removal component provided on the dust cover 8, and a collection tank 13 installed on the top of the machine base 1.
[0027] The impurity removal assembly includes a second motor 9, a rotating rod 10, and a multi-branched electromagnet 11. The second motor 9 is installed at the bottom of the dust cover 8, and the rotating rod 10 is installed at the output end of the second motor 9. Multiple multi-branched electromagnets 11 are installed on the outside of the rotating rod 10.
[0028] Specifically, when it is necessary to process the iron filings in the particles in the first container 12, the rotating rod 10 and the multi-branched electromagnet 11 are inserted into the first container 12. The second motor 9 is started to drive the rotating rod 10 to rotate. The rotating rod 10 drives the multi-branched electromagnet 11 to reciprocate, thereby adsorbing the iron filings in the particles in the first container 12, thus achieving the removal of impurities from the particles.
[0029] Furthermore, the lateral motion assembly includes a lead screw 3, a first motor 4, and a threaded plate 5. The lead screw 3 is laterally rotatably mounted inside the frame 2, and the threaded plate 5 is threadedly connected to the outside of the lead screw 3. The first motor 4 is mounted on the outside of the frame 2, and the first motor 4 is used to drive the lead screw 3 to rotate.
[0030] Specifically, when transporting the iron filings adsorbed on the multi-branched electromagnet 11 into the collection bucket 13, the first motor 4 is started to drive the lead screw 3 to rotate. The rotation of the lead screw 3 drives the threaded plate 5 to move laterally. The threaded plate 5 drives the multi-branched electromagnet 11 to be transported into the collection bucket 13. Then, the multi-branched electromagnet 11 is inserted into the collection bucket 13.
[0031] Furthermore, an electric push rod 6 is vertically installed at the bottom of the threaded plate 5, and a dust cover 8 is installed at the output end of the electric push rod 6;
[0032] Specifically, by activating the stabilizing column 7, the dust cover 8 moves up and down. The dust cover 8 then drives the second motor 9, the rotating rod 10, and the multi-branched electromagnet 11 to move up and down within the first receiving container 12, thereby increasing the range and efficiency of cleaning iron filings.
[0033] Furthermore, a stabilizing column 7 is vertically installed on the top of the dust cover 8, and the top of the stabilizing column 7 slides through the threaded plate 5;
[0034] Specifically, during the up-and-down movement of the dust cover 8, the stabilizing column 7 vertically installed at the top of the dust cover 8 slides through the threaded plate 5, thereby improving the stability of the up-and-down movement of the dust cover 8.
[0035] Furthermore, a disc-shaped electromagnet 14 is installed at the bottom of the collection bucket 13; a control area 15 is installed on the top of the machine base 1.
[0036] Specifically, when the multi-branch electromagnet 11 is inserted into the collection bucket 13, the multi-branch electromagnet 11 is de-energized by the control area 15, and the magnetic force on the multi-branch electromagnet 11 disappears. Then, the disc electromagnet 14 is energized, and the energized disc electromagnet 14 generates magnetic force, which can attract away the iron filings on the multi-branch electromagnet 11.
[0037] Working principle: When using this plastic granule removal device, to process iron filings in the granules within the first receiving tank 12, the rotating rod 10 and the multi-branched electromagnet 11 are inserted into the first receiving tank 12. The second motor 9 is activated to drive the rotating rod 10 to rotate, which in turn drives the multi-branched electromagnet 11 to reciprocate, thereby adsorbing the iron filings in the granules within the first receiving tank 12. When transporting the iron filings adsorbed on the multi-branched electromagnet 11 to the collection tank 13, the first motor 4 is activated to drive the lead screw 3 to rotate. The lead screw 3 drives the threaded plate 5 to move laterally, which in turn drives the multi-branched electromagnet 11 to be transported into the collection bucket 13. Then, the multi-branched electromagnet 11 is inserted into the collection bucket 13. At this time, the multi-branched electromagnet 11 is de-energized by the control area 15, and the magnetic force on the multi-branched electromagnet 11 disappears. Then, the disc electromagnet 14 is energized, and the energized disc electromagnet 14 generates magnetic force, which can attract away the iron filings on the multi-branched electromagnet 11.
