Description

Technical Field

[0001] This utility model belongs to the field of waste plastic recycling technology, specifically an auxiliary feeding device for plastic pellet production. Background Technology

[0002] Plastic products are widely used and closely related to people's daily lives, such as mulch film, shopping bags, water pipes, and oil drums. Granulation is a crucial step in the production of plastic products, processing raw plastic materials into granules for subsequent processing and use. With the increasing use of modern plastic products, waste plastics are becoming more and more abundant. To avoid environmental pollution, waste plastics are melted and granulated for reuse. However, in the process of recycling and granulating waste plastics, the waste plastics are first crushed into small pieces, then washed several times before being melted and granulated. Existing waste plastic recycling and granulation plants spray the crushed plastic directly onto the ground after several washes, and then manually feed the plastic blocks into the melting device. Because the waste plastics contain a lot of dust, the washed plastics still contain wastewater. Spraying the plastic directly onto the ground seriously pollutes the environment. Furthermore, manual feeding greatly increases labor intensity and reduces production efficiency. Therefore, it is necessary to design a device that prevents washed plastics from falling to the ground, collects wastewater, and can autonomously feed the plastics. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that prevents washed plastic from falling to the ground, collects wastewater, and can autonomously feed the material. This solves the problems of traditional waste plastic granulation methods, which involve directly piling up plastic containing wastewater on the ground and requiring manual feeding, resulting in low production efficiency.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: an auxiliary feeding device for plastic granule production, including a washing tank, a filter tank, and a conveying box. The filter tank and the conveying box are connected through a strip hole. A hoist is vertically fixed to one side of the washing tank. A first auger conveyor is installed inside the hoist. The side wall of the first auger conveyor is configured with a mesh structure. A feeding port is fixedly connected to the top of the first auger conveyor. The feeding port passes through the side wall of the hoist and is fixedly connected to the filter tank. A vibrating screen is inclinedly installed inside the filter tank. A vibrating motor is fixedly connected to the bottom of the vibrating screen. The downward inclined end of the vibrating screen extends through the strip hole to the top of the conveying box. A second motor is fixedly connected to the top of the conveying box. A hollow agitator is fixedly connected to the output end of the second motor. A universal joint is rotatably connected to the inner wall of the hollow agitator. An electric cylinder is fixedly connected to the bottom of the universal joint. A push plate is fixedly connected to the output end of the electric cylinder through the hollow agitator. A discharge port is opened at the bottom of the conveying box. A second auger conveyor is fixedly connected to the bottom of the discharge port. The second auger conveyor is driven by a third motor.

[0005] Furthermore, a first pulley is fixedly connected to the top of the first auger conveyor through the top wall of the elevator, a first motor is fixedly connected to one side of the elevator, and a second pulley is fixedly connected to the output end of the first motor. The first pulley and the second pulley are connected by belt drive.

[0006] Furthermore, springs are fixedly connected to the bottom of both sides of the vibrating screen, and mounting bases are fixedly connected to the bottom of the springs. The mounting bases are fixedly connected to the inner wall of the filter box.

[0007] Furthermore, the feed outlet is located above the upward-sloping side of the vibrating screen, and a water outlet is provided below the water filter box.

[0008] Furthermore, the hollow mixer has a hollow internal structure, with spiral blades fixedly connected to the outside.

[0009] This utility model has the following advantages compared with the prior art:

[0010] 1. This utility model, by setting the side wall of the first auger conveyor to a mesh structure, can initially filter most of the wastewater on the plastic and return it to the washing tank for reuse, avoiding water waste. By setting a filter box and connecting the material inlet directly to the filter box, it can prevent the plastic from falling to the ground and causing pollution to the production environment. By setting a vibrating screen, it can filter out the water on the plastic again and discharge it centrally to prevent environmental pollution. By setting a conveyor box and setting a second auger conveyor below the conveyor box, it can perform autonomous feeding, reduce manual labor intensity, and improve production efficiency.

[0011] 2. This utility model can agitate plastic by setting a hollow agitator inside the conveying box, preventing plastic from accumulating and tangling. By setting an electric cylinder inside the hollow agitator, and fixing a push plate to the output end of the electric cylinder, the plastic at the discharge port can be sent out in time, avoiding plastic blockage at the discharge port.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 The auxiliary feeding device for plastic granule production shown includes a washing tank 1, a filter tank 3, and a conveying box 4. The filter tank 3 and the conveying box 4 are connected through a slotted hole 21. To facilitate the retrieval of plastic from the washing tank 1 and the filtration of most of the wastewater, a lifting machine 2 is vertically fixed to one side of the washing tank 1. A first auger conveyor 6 is installed inside the lifting machine 2. The side wall of the first auger conveyor 6 is configured with a mesh structure. There is a certain gap between the inner wall of the lifting machine 2 and the side wall of the first auger conveyor 6. During the upward movement of the plastic, the wastewater flows from the first auger conveyor 6... The plastic is filtered out from the side wall of the auger conveyor 6 and falls into the washing tank 1 through the gap. To prevent the washed plastic from falling to the ground and causing site and environmental pollution, a feed inlet 7 is fixedly connected to the top of the first auger conveyor 6. The feed inlet 7 passes through the side wall of the elevator 2 and is fixedly connected to the filter tank 3. In order to filter out the residual wastewater in the plastic again and improve product quality, a vibrating screen 8 is inclinedly installed in the filter tank 3. A vibrating motor 23 is fixedly connected to the bottom of the vibrating screen 8. In order to collect the washed plastic for overall melting and reduce the intensity of manual labor. To improve production efficiency, the downward-sloping end of the vibrating screen 8 extends through the strip hole 21 to the top of the conveyor box 4. To prevent excessive plastic accumulation and entanglement, a second motor 11 is fixedly connected to the top of the conveyor box 4. A hollow agitator 12 is fixedly connected to the output end of the second motor 11. To enable self-cleaning when the discharge port 22 becomes blocked, a universal joint 13 is rotatably connected to the inner wall of the hollow agitator 12. The universal joint 13 consists of an inner ring and an outer ring. The outer ring is fixedly connected to the inner wall of the hollow agitator 12, and the inner and outer rings rotate... The electric cylinder 14 is fixedly connected to the inner ring to ensure that the electric cylinder 14 will not rotate with the hollow agitator 12. In order to clear the blockage when the discharge port 22 is blocked, a push plate 17 is fixedly connected through the hollow agitator 12 at the output end of the electric cylinder 14. The electric cylinder 14 is driven, and the push plate 17 moves downward to push the plastic into the second auger conveyor 15 below. In order to facilitate the conveying of the plastic to the inlet of the melting device, a second auger conveyor 15 is fixedly connected to the bottom of the discharge port 22. The second auger conveyor 15 is driven by a third motor 16.

[0018] In order to provide power to the hoist 2, a first pulley 19 is fixedly connected to the top of the first auger conveyor 6 through the top wall of the hoist 2. A first motor 5 is fixedly connected to one side of the hoist 2. A second pulley 20 is fixedly connected to the output end of the first motor 5. The first pulley 19 and the second pulley 20 are connected by belt drive.

[0019] In order to ensure that the vibrating screen 8 can follow the movement of the vibrating motor 23, springs 9 are fixedly connected to the bottom of both sides of the vibrating screen 8, and mounting bases 18 are fixedly connected to the bottom of the springs 9. The mounting bases 18 are fixedly connected to the inner wall of the water filter box 3.

[0020] To ensure that the plastic is completely loaded onto the vibrating screen 8 after being retrieved from the washing pool 1, the feed inlet 7 is located above the inclined upward side of the vibrating screen 8, and the water outlet 10 is provided below the water filter box 3.

[0021] To ensure that the drive cylinder 14 does not rotate along with it, the hollow stirrer 12 has a hollow structure inside and a spiral blade is fixedly connected to the outside.

[0022] It should be noted that, in this embodiment, in order to prevent plastic from falling into the bottom of the filter tank 3, the height of the side of the vibrating screen 8 can be set as needed to prevent plastic from falling from both sides during vibration.

[0023] The specific working process of this utility model is as follows:

[0024] After several washes, the waste plastic reaches the side of the washing tank 1 near the elevator 2. At this point, the first motor 5 is started, driving the first auger conveyor 6 to rotate. The plastic is drawn from the bottom to the top of the first auger conveyor 6. During the ascent, wastewater is filtered out from the side wall of the mesh structure and flows into the washing tank 1. When the plastic reaches the top, it flows from the feed inlet 7 onto the vibrating screen 8. At this point, the vibrating motor 23 is started, causing the vibrating screen 8 to vibrate. The remaining water flows from the bottom of the vibrating screen 8 to the water filter tank 3 for collection and discharge. The filtered plastic flows from the vibrating screen 8... The plastic enters the conveyor box 4 at the downward end. At this time, the second motor 11 is turned on, which drives the idle agitator 12 to rotate, causing the plastic in the conveyor box 4 to rotate. At the same time, the electric cylinder 14 is started, which pushes the push plate 17 downward, pushing the plastic out of the discharge port 22 and into the second auger conveyor 15. Then, the third motor 16 is started to transport the plastic out. By following the above steps for auxiliary feeding, the washing and feeding processes can be integrated, eliminating the need for manual feeding, reducing labor intensity, avoiding site pollution, and improving production efficiency.
