Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene production equipment, in particular to a polyethylene crushing and polishing device. Background Art

[0002] Plastic products are a general term for household and industrial products made from plastic as the main raw material, including products made from all processes such as injection molding and blister molding. Plastic is a material with natural or synthetic resin as the main component, with various additives added. It can be molded into a certain shape under certain conditions of temperature and pressure, and maintains its shape at room temperature. In the process of plastic product production, a large amount of waste is generated, and in order to save costs, it is usually necessary to use recycling equipment to recycle the waste.

[0003] Currently, when recycling plastic waste, workers often need to pick out the waste and perform secondary operations because the waste is large in size or hard in size, which makes it difficult to crush it in one go. The crushing efficiency is low, and there are some metal impurities in the plastic waste, which will affect the crushing effect of the plastic. Utility Model Content

[0004] The purpose of this application is to provide a polyethylene crushing and grinding device to solve the problem that the existing crushing device has low crushing efficiency and some metal impurities in plastic waste will affect the crushing effect of the plastic.

[0005] In order to solve the above technical problems, the present application provides a polyethylene crushing and grinding device, including a base and a processing box arranged above the base, a crushing box is fixed on the top side of the processing box, two crushing rollers are arranged inside the crushing box, the bottom of the crushing box is connected to the processing box, and multiple groups of magnetic separation components are staggered from top to bottom in the processing box, the magnetic separation component includes a material guide plate obliquely fixed to the side wall of the processing box, a rotating shaft is arranged above the material guide plate, the rotating shaft is movably arranged in the processing box, a magnetic roller is sleeved on the outer side of the rotating shaft, and a discharge component is arranged at the bottom of the processing box.

[0006] It should be noted in the solution that three groups of magnetic separation components are staggered from top to bottom in the processing box.

[0007] It is further worth mentioning that a box door is provided on one side of the processing box, and a pull handle is connected to the side wall of the box door.

[0008] As a preferred embodiment, a discharge port is provided at the bottom of the processing box, and the bottom of the processing box is conical.

[0009] It should be noted in the solution that the discharge assembly includes a filter plate above the discharge port, a crushed pulp is horizontally arranged above the filter plate, and one end of the crushed pulp passes through the side wall of the processing box and is connected to a discharge motor.

[0010] It is further worth mentioning that serrated plates are provided on all four sides of the crushing box.

[0011] The present invention provides a polyethylene crushing and grinding device. In actual use, plastic waste to be crushed is placed in a crushing box. An external drive device drives the crushing rollers to rotate, and the two crushing rollers rotate in opposite directions to crush the plastic. After crushing, the plastic falls onto the top guide plate in the processing box. Because the guide plate is tilted, the falling plastic waste slides downward under the action of gravity. When the plastic particles slide below the magnetic rollers, the magnetic rollers attract metal impurities in the plastic waste and absorb them. Simultaneously, the rotating shaft drives the magnetic rollers to rotate, so that the metal impurities absorbed by the magnetic rollers adhere more evenly to the surface of the magnetic rollers. After the plastic has been cleaned by the magnetic assembly, it falls to the bottom of the processing box. The discharge assembly is activated to discharge the plastic raw material out of the processing box.

[0012] Compared with the prior art, this application has at least the following beneficial effects:

[0013] 1. Two crushing rollers are set in the crushing box, and serrated plates are set around the crushing box. The combination of the crushing rollers and the serrated plates enables large pieces of plastic waste to be fully and comprehensively crushed, thereby improving the crushing efficiency;

[0014] 2. Use three sets of upper and lower magnetic separation devices to fully remove metal impurities in the plastic to prevent metal impurities from affecting the crushing effect of the plastic, which is beneficial to subsequent recycling processing;

[0015] 3. A discharge assembly is set at the bottom of the processing box. The filter plate filters the crushed plastic to make the size of the processed plastic particles more uniform. The discharge motor drives the crushing pulp to crush the large particles of plastic on the screen plate again, so that the plastic waste is fully crushed and there is no need for staff to perform secondary operations.

[0021] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] The core of this application is to provide a polyethylene crushing and grinding device, which solves the problem that the existing crushing device has low crushing efficiency and some metal impurities in plastic waste will affect the crushing effect of the plastic.

[0023] Figure 1 This is a schematic diagram of the external structure of a polyethylene crushing and grinding device provided by the utility model. Figure 2 This is a schematic diagram of the internal structure of a polyethylene crushing and grinding device provided by the utility model. Figure 3 This is a three-dimensional structural diagram of the magnetic separation component of a polyethylene crushing and grinding device provided by the utility model, see Figures 1 to 3 shown.

[0024] A polyethylene crushing and grinding device includes a base 1 and a processing box 2 arranged above the base 1. The processing box 2 is fixed above the base 1 and supported and fixed by the base 1. The size of the processing box 2 can be set according to actual conditions. A crushing box 3 is fixed to one side of the top of the processing box 2. Two crushing rollers 4 are arranged inside the crushing box 3. A driving assembly is arranged on the outer side wall of the processing box 2. Specifically, the driving assembly can be selected with reference to the existing technology. The plastic waste to be crushed is added to the crushing box 3. The driving assembly drives the crushing rollers 4 to rotate, and the two opposing crushing rollers 4 crush the plastic material transferred between them. As a preferred embodiment, serrated plates 5 are provided on all four sides of the crushing box 3. The serrated plates 5 and the crushing rollers 4 cooperate to ensure that the plastic waste put into the crushing box 3 can be fully crushed.

[0025] The bottom of the crushing box 3 is connected to the processing box 2, and the crushed plastic particles fall from the crushing box 3 into the processing box 2. The processing box 2 is staggered with multiple groups of magnetic separation components 6 from top to bottom. The magnetic separation component 6 includes a guide plate 601 fixed obliquely to the side wall of the processing box 2. A rotating shaft 602 is provided above the guide plate 601. The rotating shaft 602 is movably provided in the processing box 2. One end of the rotating shaft 602 passes through the side wall of the processing box 2 and is connected to a driving component. The driving component can drive the rotating shaft 602 in the processing box 2. The rotating shaft 602 is rotated, and a magnetic roller 603 is sleeved on the outer side of the rotating shaft 602. The crushed plastic falls onto the uppermost guide plate 601 in the processing box 2. Due to the inclined setting of the guide plate, the falling plastic waste slides downward under the action of gravity. When the plastic particles slide below the magnetic roller 603, the metal impurities in the plastic waste are attracted by the magnetic roller 603 under the magnetic attraction of the magnetic roller 603. At the same time, the rotating shaft 602 drives the magnetic roller 603 to rotate, so that the metal impurities attracted by the magnetic roller 603 are more evenly attached to the surface of the magnetic roller 603. Preferably, three groups of magnetic separation assemblies 6 are staggered from top to bottom in the processing box 2. The three groups of magnetic separation devices are used to fully remove metal impurities in the plastic, preventing the metal impurities from affecting the crushing effect of the plastic, thereby facilitating subsequent recycling processing.

[0026] like Figure 1 As shown, a door 11 is provided on one side of the processing box 2, and a pull handle is connected to the side wall of the door 11. The door 11 and the pull handle are provided to facilitate the staff to clean the metal impurities in the processing box 2.

[0027] To further ensure a more uniform size of processed plastic particles, a discharge assembly is provided at the bottom of the processing box 2. Furthermore, the discharge assembly includes a filter plate 9 above the discharge port 10. The filter pore size of the filter plate 9 is set according to actual needs. Plastic particles that meet the requirements pass through the filter pores of the filter plate 9 and are directly discharged from the processing box 2. A crushing slurry 8 is disposed horizontally above the filter plate 9. One end of the crushing slurry 8 extends through the side wall of the processing box 2 and is connected to a discharge motor 7. During actual use, the discharge motor 7 is activated, and the crushing slurry 8 is driven by the discharge motor 7 to further crush the large plastic particles above the filter plate 9. The rotating crushing slurry 8 also prevents clogging of the filter plate 9, accelerating the discharge of the processed plastic particles.

[0028] In this embodiment, a discharge port 10 is provided at the bottom of the processing box 2 , and the bottom of the processing box 2 is tapered. The tapered processing box 2 can prevent the processed raw materials from falling into the corners and allow them to be discharged directly through the discharge port 10 .

[0029] The polyethylene crushing and grinding device provided herein is designed to crush plastic waste material. During actual use, the plastic waste to be crushed is added to the crushing box 3. The drive assembly drives the crushing rollers 4 to rotate, and the two opposing crushing rollers 4 crush the plastic material placed between them. Simultaneously, the serrated plate 5 and crushing rollers 4 cooperate to ensure that the plastic waste placed in the crushing box 3 is fully crushed. After crushing, the plastic material falls onto the top guide plate 601 in the processing box 2. Due to the inclined setting of the guide plate, the falling plastic waste slides downward under the action of gravity. When the plastic particles slide below the magnetic roller 603, the magnetic attraction of the magnetic roller 603 attracts metal impurities in the plastic waste. Simultaneously, the drive shaft 602 drives the magnetic roller 603 to rotate, so that the metal impurities attracted by the magnetic roller 603 adhere more evenly to the surface of the magnetic roller 603. After impurities are removed, the plastic particles that meet the requirements pass through the filter holes of the filter plate 9 and are directly discharged from the processing box 2. Simultaneously, the discharge motor 7 drives the crushing slurry 8 to further crush the large plastic particles above the filter plate 9.
