Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling technology, and in particular relates to a plastic particle impurity removal and sorting device. Background Technology

[0002] Against the backdrop of the continuous development of the plastics industry, the recycling and reuse of plastic waste has become an important measure to save resources and reduce environmental pollution. As a key intermediate product for recycling, the purity of plastic granules directly affects the quality of subsequent processed products. Therefore, it is essential to effectively remove impurities and sort plastic granules to remove light impurities, iron impurities, etc.

[0003] Existing plastic particle sorting and removal devices typically pour the material into a screen and sieve it to remove lightweight and ferrous impurities, leaving plastic particles inside. However, the plastic particles, lightweight and ferrous impurities are of different sizes and diameters, which may prevent larger lightweight and ferrous impurities from passing through the screen holes. This necessitates further sorting of the remaining impurities by staff. This method is not quick and effective in sorting and removing impurities from plastic particles, resulting in a decrease in overall sorting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a plastic particle impurity removal and sorting device. By setting up a sorting mechanism, specifically a motor, a fan, and two electromagnets, the motor drives an eccentric shaft to rotate. When the convex end contacts the lifting box, it pushes the box upwards; when it is not in contact, the lifting box moves downwards. The continuous rotation of the eccentric shaft causes the lifting box to vibrate continuously within the lifting groove, causing the internal material to bounce and fly up. The blowing force generated by the fan blows light impurities such as plastic particles towards the receiving pipe, allowing them to enter the light impurity collection container. The plastic particles are intercepted by the filter screen. Simultaneously, the electromagnets generate magnetic force, attracting ferrous impurities in the material to their surface. This setup can quickly and efficiently sort different impurities, leaving only plastic particles. It solves the problem that existing sorting devices mostly use sieves to separate different impurities, but larger diameter impurities are difficult to pass through the sieve holes, ultimately requiring workers to continue sorting the impurities.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a plastic granule impurity removal and sorting device, including a feeding box, a sorting box fixedly connected to the top of the feeding box, and further comprising:

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-6 As shown, this utility model is a plastic particle impurity removal and sorting device, including a feeding box 1, a sorting box 11 fixedly connected to the top of the feeding box 1, and further including:

[0037] Sorting mechanism 2 is located at the bottom and inside of sorting box 11. Sorting mechanism 2 is used to sort different impurities. Sorting mechanism 2 includes a lifting box 24, a lifting groove 241 at the bottom of sorting box 11, and an eccentric shaft 231 below the lifting box 24; and

[0038] The feeding mechanism 3 is located inside the lifting box 24 and the feeding box 1. The feeding mechanism 3 is used for sorting and discharging materials. The top of the sorting box 11 is fixedly connected to the hopper 12, and the bottom of the hopper 12 is connected to the top of the sorting box 11.

[0039] A fan 21 is installed on the front of the sorting box 11, and a receiving pipe 211 is fixedly connected to the back of the sorting box 11. Electromagnets 22 are installed on the left and right sides of the inner wall of the sorting box 11. Filter screens are installed on the back of the fan 21 and the front of the receiving pipe 211. The filter screens are used to prevent plastic particles from entering the inside of the fan 21 and the receiving pipe 211.

[0040] The feeding mechanism 3 includes a rack 33, a dust cover 31 is fixedly connected to the right side of the lifting box 24, and several flip plates 32 are rotatably connected inside the lifting box 24; among them, gear 321 is fixedly connected to the right side of each of the several flip plates 32, and the rack 33 is meshed with the several gears 321.

[0041] A motor 23 is fixedly connected to the front of the feeding box 1. The output end of the motor 23 is fixedly connected to the front of the eccentric shaft 231 via a coupling. When the motor 23, the fan 21, and the two electromagnets 22 are started, the motor 23 drives the eccentric shaft 231 to rotate. When its convex end contacts the lifting box 24, it pushes the lifting box 24 upward. When it does not contact the lifting box 24, it moves downward. The continuous rotation of the eccentric shaft 231 causes the lifting box 24 to vibrate continuously in the lifting groove 241, causing the internal material to bounce and fly up. The blowing force generated by the fan 21 blows light impurities such as plastic particles toward the receiving pipe 211, so that they enter the light impurity collection container. The plastic particles are intercepted by the filter screen. At the same time, the electromagnets 22 generate magnetic force to attract iron impurities in the material to their surface. This setting can quickly and efficiently sort different impurities, leaving only plastic particles. The lifting box 24 and the lifting groove 241 are in sliding limit cooperation, and the top of the eccentric shaft 231 abuts against the bottom of the lifting box 24.

[0042] The rack 33 has two sliding grooves 331 inside. The lifting box 24 has two limiting blocks 332 fixedly connected to the right side. The two limiting blocks 332 are respectively slidably limited and cooperate with the two sliding grooves 331. The lifting box 24 has a rotating groove 34 on the right side. A rotating rod 341 is rotatably connected inside the rotating groove 34. A gear 342 is fixedly connected to the right side of the outer surface of the rotating rod 341. The gear 342 meshes with the rack 33.

[0043] The lifting box 24 has a moving groove 35 on the right side, and a moving rod 351 is slidably limited inside the moving groove 35. A locking block 352 is fixedly connected to the right end of the moving rod 351. The locking block 352 is inserted into two adjacent teeth of the gear 342. A spring 353 is fixedly connected to the left side of the moving rod 351. The left end of the spring 353 is fixedly connected to the inner wall of the moving groove 35. An operation window 354 is opened on the right side of the feeding box 1.

[0044] The front of the feeding box 1 has an inclined groove 36, and an insert plate 361 is inserted into the inclined groove 36. Pull out the locking block 352 to disengage it from the gear 2 342. Rotate the rotating rod 341 and the gear 2 342 clockwise. The rack 33 moves to the back, and several flip plates 32 rotate clockwise. After reaching the limit position, the locking block 352 is released. The spring 353 pulls the locking block 352 back into the adjacent teeth of the gear 2 342. The plastic particles fall into the insert plate 361 in the feeding box 1 through the gap between the adjacent flip plates 32, and the feeding cover 37 is opened. The plastic particles fall into the container through the slot. After discharge, the feeding cover 37 is inserted back, the insert plate 361 is pulled out, and the two electromagnets 22 are turned off. The iron impurities fall into the feeding box 1 and finally enter the iron collection container. The inclined groove 36 extends into the interior of the feeding box 1. The inclined groove 36 and the insert plate 361 are both inclined. The left side of the feeding box 1 has a slot, and the feeding cover 37 is inserted into the slot.

[0045] A specific application of this embodiment is as follows: In use, first pour the material into the hopper 12, then cover the hopper 12 with a cover plate. Next, start the blower 21, the two electromagnets 22, and the motor 23 respectively. Simultaneously, connect one end of the hose to the receiving pipe 211 and the other end to the light impurity collection container. The motor 23 will drive the eccentric shaft 231 to rotate. When the eccentric shaft 231 rotates, its protruding end contacts the lifting box 24, pushing the lifting box 24 upwards within the lifting groove 241. When the protruding end stops contacting the lifting box 24... If the material moves downwards, the eccentric shaft 231 will continue to rotate, causing the lifting box 24 to vibrate continuously, making the material inside constantly bounce and fly up. The blowing force generated by the fan 21 will blow light impurities such as plastic particles toward the receiving pipe 211. The light impurities will enter the inside of the receiving pipe 211 and eventually enter the light impurity collection container, while the plastic particles will be intercepted by the filter screen. When the material bounces and flies up, the electromagnet 22 (Landa H2004525) generates magnetic force, attracting iron impurities in the material to the surface of the electromagnet 22.

[0046] This process is repeated to sort different impurities. Then, the operator reaches into the operating window 354 and pulls out the locking block 352, preventing it from contacting gear two 342. At this point, gear two 342 is unlocked, and spring 353 is stretched. Then, the rotating rod 341 is rotated clockwise, causing gear two 342 to rotate accordingly. The rack 33 moves backward, and since several gears one 321 are engaged with the rack 33, several flip plates 32 rotate clockwise. After reaching their limit position, the locking block 352 is released, and spring 353, through its own elasticity, pulls the moving rod 351 and the locking block. Block 352 is reset, and locking block 352 re-enters between two adjacent teeth of gear 2 342. At this time, plastic particles will fall through the gap between two adjacent flip plates 32 into the insert plate 361 in the feeding box 1. Then, place the plastic collection container on the left side of the feeding box 1 and open the feeding cover 37. The plastic particles will fall into the plastic collection container through the slot. After the plastic particles are discharged, insert the feeding cover 37 back, pull out the insert plate 361, and place the iron collection container below the feeding box 1. At the same time, turn off the two electromagnets 22. The iron impurities that lose their adsorption will fall into the feeding box 1 and eventually into the iron collection container.
