Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling, and in particular relates to a plastic recycling device with a cleaning function. Background Art

[0002] Plastic recycling refers to the use of a certain recycling process to recycle and reuse waste plastics in order to achieve the goal of turning waste into treasure. This process not only helps to reduce environmental pollution, but also achieves the reuse of resources, which has important environmental and economic significance. my country's waste plastics mainly include plastic films, plastic threads and woven products, foam plastics, plastic packaging boxes and containers, daily plastic products, plastic bags and agricultural mulch films. According to different materials and uses, waste plastics can be classified and recycled. In the process of plastic recycling, the current common method is mainly mechanical crushing to divide plastic waste into plastic particles for recycling.

[0003] Conventional plastic recycling equipment is mainly composed of a mechanical crushing device. Plastic particles can be obtained by feeding plastic waste into the crushing device. However, when the crushing device currently used is used to crush plastic particles, it involves grinding of plastic particles, which will cause a certain amount of dust. At the same time, due to the dirtiness of the plastic waste itself, the recycled plastic particles contain a lot of dust, which affects the recycling effect.

[0004] At the same time, during the recycling process of plastic particles, a certain amount of liquid will remain inside some plastic waste, such as plastic bottles. During the recycling process, this part of the liquid will mix with the plastic particles, causing the plastic particles to be mixed with sewage. This will not only affect the quality of the plastic particles, but there is also the possibility of pipe blockage due to sewage, which urgently needs to be improved. Summary of the invention

[0007] Before recycling plastic waste, the device can be connected to an external power supply, and the external high-pressure water pipe can be connected to the device. Cleaning liquid can be added to the inside of the cleaning component as needed. At the same time, a sewage receiving tank and a plastic particle recovery tank must be placed on the front and rear sides of the bottom of the dehydration component respectively to complete the preparations before plastic recycling.

[0008] As a further technical solution of the present invention, the crushing assembly includes a crushing box, a grinding box is fixedly installed at the lower left corner of the crushing box, the bottom end of the crushing box is connected to a position on the right side of the grinding box near the top through a curved pipe, and the top of the crushing box is fixedly connected with a feed port.

[0009] As a further technical solution of the present invention, the bottom end of the grinding box is connected to the top end of the base, a crushing blade is provided inside the crushing box, the crushing box is movably connected to the main shaft, the crushing blade is fixedly sleeved to the outer side surface of the main shaft, the first power shaft is movably connected to the grinding box, and the outer side surface of the first power shaft is fixedly sleeved with a grinding blade located inside the grinding box.

[0011] As a further technical solution of the present invention, a driven gear is meshedly connected above the driving gear, and the driven gear is fixedly sleeved on the middle part of the main shaft and located between the crushing box and the dehydration component.

[0012] When it is necessary to crush and recycle plastic particles, the plastic waste can be put into the crushing box through the feed port and the motor can be started. At this time, the driving gear can be driven to rotate. When the driving gear rotates, the power can be transmitted to the driven gear, and the main shaft can be driven to rotate, while the torque is amplified. At this time, the first bevel gears at the left and right ends of the main shaft rotate accordingly, and at the same time drive the second bevel gear in the meshing state to rotate, completing the reversal, and finally realizing the synchronous rotation of the first power shaft and the second power shaft.

[0013] When the main shaft rotates, the crushing blade can be driven to rotate, that is, the plastic waste inside the crushing box is cut to complete the initial cutting process. The cut plastic fragments then enter the interior of the grinding box through the curved pipe at the bottom, and the rotation of the first power shaft can drive the grinding blade to rotate, and grind the plastic fragments inside the grinding box to transform them into plastic particles, which are discharged through the first feed pipe at the bottom, and as the plastic particles are ground, the plastic particles are transported to the interior of the cleaning component.

[0014] As a further technical solution of the present invention, the cleaning assembly includes a cleaning box, the bottom end of the cleaning box is connected to the bottom end of the grinding box through a first material delivery pipe, the middle part of the cleaning box is movably connected to the second power shaft, the outer side surface of the second power shaft is fixedly sleeved with a cleaning impeller located inside the cleaning box, the right side of the cleaning box near the top is connected to the second material delivery pipe, the front and rear sides of the top of the cleaning box are fixedly connected with water injection pipes, the two water injection pipes are fixedly connected with a three-way valve, and the top of the three-way valve is connected to the external high-pressure water pipe.

When the second power shaft rotates, the cleaning impeller can be driven to rotate synchronously. At this time, the plastic particles entering the cleaning box can come into contact with the high-speed rotating high-pressure water flow and mix with it, completing the rapid cleaning process of the plastic particles. At the same time, the high-speed water flow can also complete the dust reduction process of the plastic particles.

[0016] By utilizing the power of plastic particle crushing to complete the cutting and crushing of plastic waste, its mechanical power can be combined with the input high-pressure water flow to achieve high-speed contact between water flow and plastic particles. Through its mixing action, the dust generated when the plastic waste is crushed can be quickly reduced and mixed with clean water. At the same time, the dirt on the surface of plastic particles can be quickly removed, realizing the automatic cleaning process of plastic particles and improving the recycling effect.

[0017] As a further technical solution of the present invention, the dehydration assembly includes a dehydration box, which is fixedly installed at the upper right corner of the cleaning box. The middle part of the dehydration box is movably connected to the main shaft. The outer side surface of the main shaft is fixedly sleeved with a centrifugal tank located inside the dehydration box. One end of the outer side surface of the centrifugal tank is movably clamped with a closed cover plate, and the outer side surface of the centrifugal tank is circumferentially provided with a water filter hole.

[0019] After cleaning is completed, the valve of the second feeding pipe can be opened to allow the plastic particles mixed with clean water to be transported into the interior of the dehydration box through the second feeding pipe. During transportation, the mixed liquid loaded with plastic particles can be put into the interior of the centrifugal tank by opening the closed cover plate, so that all the plastic particles enter the interior of the centrifugal tank. After the feeding is completed, the closed cover plate is closed, and the centrifugal tank can be driven to rotate at a high speed as the main shaft rotates. At this time, the water flow can be thrown out through the water filter hole, enter the interior of the dehydration box, and be discharged through the drainage pipe at the front end, while the dehydrated plastic particles stay on the inner side of the centrifugal tank. After all dehydration is completed, the centrifugal tank can be rotated so that the closed cover plate corresponds to the discharge trough, and the closed cover plate can be opened to discharge the dehydrated plastic particles through the discharge trough.

[0020] By reusing the power of crushing and recycling plastic particles, that is, putting the cleaned mixture into the interior of the dehydration component, the dehydration component converts the mechanical force into centrifugal force, so as to achieve rapid separation of water flow and plastic particles, and then complete the rapid dehydration of plastic particles, so that the recycled plastic particles can be cleaned and dehydrated, so that there is no sewage in the discharged plastic particles, which significantly improves the quality of the plastic particles.

[0021] As a further technical solution of the present invention, an air collecting box is provided on one side of the transmission shaft, the top of the air collecting box is connected to the bottom end of the dehydration box, the transmission shaft passes through the middle of the air collecting box and is movably connected to the air collecting box, and the outer side surface of the transmission shaft is fixedly sleeved with a negative pressure impeller located inside the air collecting box.

[0024] By further utilizing the mechanical force used in crushing and recycling plastic particles, the rotational power is converted into negative pressure power, the active absorption of air is realized and acts on the discharge process of the plastic particles. The plastic particles can be automatically dried by heating the air and their discharge is accelerated. The entire process does not require manual control, which can further improve the quality of plastic recycling and improve practicality.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention utilizes the power of plastic particles during crushing to complete the cutting and crushing of plastic waste. It can also utilize its mechanical power in conjunction with the input high-pressure water flow to achieve high-speed contact between the water flow and the plastic particles. Through its mixing action, the dust generated during the crushing of the plastic waste is quickly reduced and mixed with clean water. At the same time, the dirt on the surface of the plastic particles can be quickly removed, thereby realizing the automatic cleaning process of the plastic particles and improving the recycling effect.

The whole process does not require manual control, which can further improve the quality of plastic recycling and improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS

A driven gear 705 is meshed and connected above the driving gear 704. The driven gear 705 is fixedly sleeved on the middle part of the main shaft 2 and is located between the crushing box 801 and the dehydration component 12.

[0042] When it is necessary to crush and recycle the plastic particles, the plastic waste can be put into the crushing box 801 through the feed port 802, and the motor 702 can be started. At this time, the driving gear 704 can be driven to rotate.

As the plastic particles are ground, the plastic particles are transported to the inside of the cleaning component 11.

[0044] like Figure 1 and Figure 2 as well as Figure 5 and Figure 6 As shown, the cleaning component 11 includes a cleaning box 111, the bottom end of the cleaning box 111 is connected to the bottom end of the grinding box 803 through the first feed pipe 9, the middle part of the cleaning box 111 is movably connected to the second power shaft 6, the outer side surface of the second power shaft 6 is fixedly sleeved with a cleaning impeller 112 located inside the cleaning box 111, the right side of the cleaning box 111 near the top is connected to the second feed pipe 10, the front and rear sides of the top of the cleaning box 111 are fixedly connected with a water injection pipe 113, the two water injection pipes 113 are fixedly connected with a three-way valve 114, and the top of the three-way valve 114 is connected to an external high-pressure water pipe.

[0045] Embodiment: When the plastic particles are transported to the interior of the cleaning box 111 through the first feed pipe 9, the external high-pressure water pipe can be opened to input the high-pressure water flow into the interior of the three-way valve 114, and after being transported through the water injection pipe 113, the high-pressure water flow can enter the interior of the cleaning box 111, and when the second power shaft 6 rotates, the cleaning impeller 112 can be synchronously driven to rotate. At this time, the plastic particles entering the cleaning box 111 can come into contact with the high-speed rotating high-pressure water flow and mix with it, completing the rapid cleaning process of the plastic particles. At the same time, the high-speed water flow can also complete the dust reduction process of the plastic particles.

[0046] By utilizing the power of plastic particle crushing to complete the cutting and crushing of plastic waste, its mechanical power can be combined with the input high-pressure water flow to achieve high-speed contact between water flow and plastic particles. Through its mixing action, the dust generated when the plastic waste is crushed can be quickly reduced and mixed with clean water. At the same time, the dirt on the surface of plastic particles can be quickly removed, realizing the automatic cleaning process of plastic particles and improving the recycling effect.

[0047] like Figure 2 and Figure 7 as well as Figure 8 As shown, the dehydration assembly 12 includes a dehydration box 121, which is fixedly installed at the upper right corner of the cleaning box 111, and the middle part of the dehydration box 121 is movably connected to the main shaft 2. The outer side surface of the main shaft 2 is fixedly sleeved with a centrifugal tank 125 located inside the dehydration box 121, and one end of the outer side surface of the centrifugal tank 125 is movably clamped with a closed cover plate 126, and the outer side surface of the centrifugal tank 125 is circumferentially provided with a water filter hole 127, and the front end of the dehydration box 121 is fixedly connected to a drain pipe 122 near the bottom end, and the rear end of the dehydration box 121 is fixedly connected to a discharge trough 123 near the top end, and the front end of the discharge trough 123 is provided with an air inlet 124 near the bottom end.

[0048] Embodiment: After cleaning is completed, the valve of the second feeding pipe 10 can be opened to allow the plastic particles mixed with clean water to be transported into the interior of the dehydration box 121 through the second feeding pipe 10. During transportation, the mixed liquid loaded with plastic particles can be put into the interior of the centrifugal tank 125 by opening the closed cover 126, so that all the plastic particles enter the interior of the centrifugal tank 125. After the feeding is completed, the closed cover 126 is closed, and the centrifugal tank 125 can be driven to rotate at a high speed as the main shaft 2 rotates.

[0052] By further utilizing the mechanical force used in crushing and recycling plastic particles, the rotational power is converted into negative pressure power, the active absorption of air is realized and acts on the discharge process of the plastic particles. The plastic particles can be automatically dried by heating the air and their discharge is accelerated. The entire process does not require manual control, which can further improve the quality of plastic recycling and improve practicality.

[0053] Working principle and usage process:

[0054] Before recycling plastic waste, the device can be connected to an external power source, and an external high-pressure water pipe can be connected to the device, and cleaning liquid can be added to the inside of the cleaning component 11 as needed. At the same time, a sewage receiving tank and a plastic particle recovery tank need to be placed on the front and rear sides of the bottom of the dehydration component 12, respectively, to complete the preparation before plastic recycling;

[0055] When it is necessary to crush and recycle the plastic particles, the plastic waste can be put into the crushing box 801 through the feed port 802, and the motor 702 can be started. At this time, the driving gear 704 can be driven to rotate. When the driving gear 704 rotates, the power can be transmitted to the driven gear 705, and the main shaft 2 can be driven to rotate, and the torque can be amplified at the same time. At this time, the first bevel gears 3 at the left and right ends of the main shaft 2 rotate accordingly, and at the same time drive the second bevel gear 4 in the meshing state to rotate, completing the reversal, and finally realizing the synchronous rotation of the first power shaft 5 and the second power shaft 6.

[0056] When the main shaft 2 rotates, the crushing blade 805 can be driven to rotate, that is, the plastic waste inside the crushing box 801 is cut to complete the preliminary cutting process, and the cut plastic fragments then enter the inside of the grinding box 803 through the curved pipe at the bottom, and the rotation of the first power shaft 5 can drive the grinding blade 804 to rotate, and grind the plastic fragments inside the grinding box 803 to convert them into plastic particles, which are discharged through the first feeding pipe 9 at the bottom, and as the plastic particles are ground, the plastic particles are transported to the inside of the cleaning component 11;

[0057] When the plastic particles are transported to the inside of the cleaning box 111 through the first feeding pipe 9, the external high-pressure water pipe can be opened to input the high-pressure water flow into the inside of the three-way valve 114, and the high-pressure water flow can enter the inside of the cleaning box 111 after being transported through the water injection pipe 113. When the second power shaft 6 rotates, the cleaning impeller 112 can be synchronously driven to rotate. At this time, the plastic particles entering the cleaning box 111 can contact with the high-speed rotating high-pressure water flow and mix with it, completing the rapid cleaning process of the plastic particles. At the same time, the high-speed water flow can also complete the dust reduction process of the plastic particles;

[0058] After cleaning is completed, the valve of the second feeding pipe 10 can be opened to allow the plastic particles mixed with clean water to be transported into the dehydration box 121 through the second feeding pipe 10. During transportation, the mixed liquid loaded with plastic particles can be put into the centrifugal tank 125 by opening the closed cover plate 126, so that all the plastic particles enter the centrifugal tank 125. After the feeding is completed, the closed cover plate 126 is closed, and the centrifugal tank 125 can be driven to rotate at a high speed as the main shaft 2 rotates. At this time, the water flow can be thrown out through the water filter hole 127 and enter the interior of the dehydration box 121, and discharged through the drainage pipe 122 at the front end, and the dehydrated plastic particles stay on the inner side of the centrifugal tank 125. After all dehydration is completed, the centrifugal tank 125 can be rotated so that the closed cover plate 126 corresponds to the discharge trough 123, and the closed cover plate 126 can be opened to discharge the dehydrated plastic particles through the discharge trough 123.

[0059] When the main shaft 2 rotates, that is, the transmission shaft 703 rotates, it can drive the negative pressure impeller 707 to rotate at high speed and generate negative pressure inside the air collecting box 706, that is, the external air is sucked into the inside of the air collecting box 706, and discharged through the air supply pipe 708, and heated by the electric heating pipe 709 to form high-speed flowing hot air, which can now fully contact the plastic particles discharged from the discharge trough 123, complete the drying of the surface of the plastic particles and accelerate the flow of the plastic particles, thereby completing the discharge process of the recycled plastic particles.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
