Description

Technical Field

[0001] This utility model relates to the technical field of plastic cleaning equipment, and more specifically, to a plastic crushed material cleaning device. Background Technology

[0002] With continuous economic development, the consumption of plastic products is constantly increasing, leading to a corresponding increase in the amount of waste plastic. To protect the environment, cleaning waste plastic is a crucial step in the recycling process. Most existing waste plastic cleaning systems consist of a series of components, including crushers, friction washers, several dewatering machines, several rinsing tanks, and several screw conveyors. While such systems can handle large quantities of waste plastic, they have a large footprint, require a large number of devices resulting in high energy consumption, and because the surface dirt is not removed through high-speed friction between the crushed plastic and the blades in the friction washer, a large amount of microplastic powder is easily generated and discharged into the wastewater, causing secondary environmental pollution.

[0003] Currently, while there are waste plastic processing devices on the market that integrate at least two functions such as crushing, washing, rinsing, and dewatering, most of these devices are equipped with paddle structures. The high-speed rotation of these paddles causes friction and cleaning with the crushed plastic material, removing surface contaminants. However, the friction between the paddle structure and the crushed plastic material generates a large amount of plastic fragments and powder. These fragments and powder are discharged into the wastewater treatment plant along with the contaminants, increasing the load on the wastewater treatment plant and potentially reducing the yield of finished plastic products after washing.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0021] Example 1 like Figures 1 to 3 The first embodiment of the plastic crushing and cleaning device of the present invention is shown. It includes a cleaning tank 100, a feeding port 110, a rotating mechanism 200, and several hoppers 300. The hoppers 300 are located inside the cleaning tank 100 and are connected to the rotating drive end of the rotating mechanism 200. The hoppers 300 are provided with a communication structure for communicating with the inside of the cleaning tank 100.

[0022] The cleaning tank 100 is used to hold cleaning agents or water for cleaning or rinsing plastic fragments. The hopper 300 is used to hold the plastic fragments. The rotating mechanism 200 is used to drive the hopper 300 and the plastic fragments inside it to rotate within the cleaning tank 100. During rotation, water flows in and out of the hopper 300 through the connecting structure to achieve cleaning, reducing the generation of plastic fragments and powder, and improving the yield of finished plastic products after cleaning. After cleaning, the rotation of the rotating mechanism 200 can also drive airflow through the connecting structure to achieve dehydration, improving the processing efficiency of the cleaning device for plastic fragments. In this embodiment, the cross-sectional area of ​​the connecting structure is smaller than any cross-sectional area of ​​the plastic fragments, which can prevent the plastic fragments from leaking out of the hopper. This utility model provides a plastic fragment cleaning device that can be used for cleaning hard plastic fragments.

[0023] like Figure 1 and Figure 2As shown, the connecting structure includes multiple through holes on the hopper 300. The cross-sectional area of ​​the through holes is smaller than any cross-sectional area of ​​the plastic crushed material. Preferably, the hopper 300 is a mesh hopper. The mesh hopper can prevent the plastic crushed material from leaking out and can also facilitate the rapid and sufficient contact between water flow or air flow and the plastic crushed material in the hopper 300, thereby improving the processing efficiency of the plastic crushed material.

[0024] like Figure 2 As shown, the hopper 300 includes a hopper body 310 and a hopper door 320 movably connected to the hopper body 310. The hopper body 310 and / or the hopper door 320 have a communicating structure, and a fastening structure is also provided between the hopper body 310 and the hopper door 320. The hopper body 310 is connected to the rotation drive end of the rotating mechanism 200. Both the hopper body 310 and the hopper door 320 have a mesh structure. In this embodiment, the hopper door 320 includes a first door panel 321 and a second door panel 322. One side edge of the first door panel 321 is angled to the second door panel 322. Specifically, the first door panel 321 and the second door panel 322 are perpendicular to each other. The first door panel 321 is used to cover the opening of the hopper body 310, and the second door panel 322 covers the outer wall of the hopper body 310. The opposite sides of the first door panel 321 are connected... A first pivot 330 is provided, and a first door panel 321 is connected to the opening of the hopper body 310 via the first pivot 330, allowing the hopper door 320 to rotate open or close. A fastening structure is provided between the second door panel 322 and the outer wall of the hopper body 310. Specifically, the fastening structure may include male and female fasteners respectively provided on the second door panel 322 and the hopper body 310, or structures with concave and convex portions respectively, which facilitates the opening and closing of the hopper door 320 relative to the hopper body 310, and facilitates material feeding and retrieval. In this embodiment, the hopper 300 can be a rectangular, columnar, or other contour structure, and the specific contour structure can be selected according to the actual application scenario.

[0025] like Figure 1 As shown, the inlet 110 is located at the top of the cleaning tank 100, and the outlet 120 is located at the bottom of the cleaning tank 100. An on / off control device is provided at the outlet 120. In this embodiment, the on / off control device can be a valve. The end of the cleaning tank 100 near the outlet 120 is funnel-shaped to facilitate material discharge. It should be noted that a cover can also be provided at the inlet 110 to cover the inlet 110 during the cleaning process and prevent liquid from splashing out.

[0026] like Figure 1 and Figure 3As shown, the rotating mechanism 200 includes a rotating drive component, a transmission component 210, and several connecting rods 220. The connecting rods 220 are drivenly connected to the rotating drive component via the transmission component 210. The connecting rods 220 are located inside the cleaning tank 100 and connected to the hopper 300. The transmission component 210 is rotatably connected to the side wall of the cleaning tank 100, and the rotating drive component is located outside the cleaning tank 100. In this embodiment, the transmission component 210 is a second rotating shaft, and the rotating drive component is a rotary motor. The base of the rotary motor is connected to the outer side wall of the cleaning tank 100 via a connecting component. One end of the second rotating shaft is drivenly connected to the output end of the rotary motor, and the other end of the second rotating shaft extends into the cleaning tank 100. The two ends of the connecting rods 220 are respectively connected to the second rotating shaft and the hopper 310. The connection rods 220 increase the moving area of ​​the hopper 300 within the cleaning tank 100, thereby improving the processing efficiency of crushed plastic materials. In this embodiment, the axis of the second rotating shaft extends horizontally. The connecting component for the rotating motor can be a connecting seat, which is installed on the outer wall of the cleaning tank 100, and the base of the rotating motor is mounted on the connecting seat. In this embodiment, the transmission component 210 is connected to the cleaning tank 100 through a bearing. To prevent liquid leakage from the cleaning tank 100, an existing sealing structure is used to seal the bearing, specifically, a sealing rubber ring can be selected as the sealing structure.

[0027] To enable the cleaning device to complete the cleaning of plastic shreds in batches, at least two hoppers 300 can be set in this embodiment. Multiple hoppers 300 can be evenly distributed in the cleaning tank 100. Preferably, four hoppers 300 are set in the cleaning tank 100. Each hopper 300 is connected to the second rotating shaft through a connecting rod 220. The extension direction of the connecting rod 220 can be set to be perpendicular to the axis of the second rotating shaft, so that the hopper 300 can rotate in the vertical plane in the cleaning tank 100.

[0028] The working principle of the plastic crushing and washing device in this embodiment is as follows: The plastic shreds to be cleaned are placed into the bin 310, and the bin door 320 is closed by the fastening structure. Cleaning agent is injected into the cleaning tank 100 through the feed port 110, and the rotating mechanism 200 is started to make the mesh bin rotate at high speed. During the rotation of the mesh bin, the cleaning agent forms a high-speed fluid through the mesh of the mesh bin to clean the plastic shreds in the mesh bin. After cleaning, the cleaning agent can be discharged or poured out through the discharge port 120. Then, clean water is injected into the cleaning tank 100 to rinse the plastic shreds in the rotating mesh bin. After rinsing, the liquid in the cleaning tank 100 is also discharged. Then, the rotating mechanism 200 is started again to make the mesh bin rotate at high speed. The high-speed airflow generated during the rotation can be used to remove the clean water remaining on the plastic shreds. After dehydration, the bin door 320 is opened, and the valve at the discharge port 120 is opened. The rotating mechanism 200 is started again, and the plastic shreds can be discharged through the discharge port 120 during the rotation.

[0029] Example 2 This embodiment is a second embodiment of a plastic crushing and washing device. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 1 and Figure 3 As shown, the plastic crushed material washing device also includes a pool and a flow guiding mechanism 600. The pool is connected to the washing tank 100 via the flow guiding mechanism 600. The pool can be used to hold clean water or cleaning agent. The pool and the flow guiding mechanism 600 are designed to facilitate the rapid introduction of clean water or cleaning agent, improving the processing efficiency of the plastic crushed material. At least two pools are provided, each capable of holding at least one clean water and one cleaning agent; each pool is connected to the washing tank 100 via the flow guiding mechanism 600. In this embodiment, two pools are provided: a first pool 400 for holding the cleaning agent and a second pool 500 for holding clean water. The flow guiding mechanism 600 includes a first conduit 610 and a first pump 620. The first pool 400 is connected to the cleaning tank 100 through the first conduit 610, and the first pump 620 is installed in the first conduit 610. The flow guiding mechanism 600 also includes a second conduit 630 and a second pump 640. The second pool 500 is connected to the cleaning tank 100 through the second conduit 630, and the second pump 640 is installed in the second conduit 630.

[0030] like Figure 3As shown, in order to improve the cleaning and rinsing efficiency, at one end of the cleaning tank 100, the first conduit 610 and the second conduit 630 are both inserted into the cleaning tank 100 from the top of the cleaning tank 100. This allows the cleaning agent to be introduced into the cleaning tank 100 through the first conduit 610 or the clean water to be introduced into the cleaning tank 100 through the second conduit 630, thereby rinsing the hopper 300 and the plastic crushed material inside and improving the processing efficiency of the plastic crushed material. At one end of the pool, in order to facilitate the discharge of liquid, the first conduit 610 and the second conduit 630 can be extended into the first pool 400 and the second pool 500 near the bottom of the pool, respectively.

[0031] The working principle of the plastic crushing and washing device in this embodiment is as follows: In the cleaning step, the first pump body 620 is turned on to introduce cleaning agent into the cleaning tank 100 through the first conduit 610 from the top, and at the same time the rotating mechanism 200 is started to make the mesh hopper rotate at high speed; in the rinsing step, the second pump body 640 is turned on to introduce clean water into the cleaning tank 100 through the second conduit 630 from the top, and the mesh hopper can complete rinsing during rotation.

[0032] Example 3 This embodiment is a third embodiment of a plastic crushing and washing device. This embodiment is similar to embodiment one or two, except that, as shown in the example... Figure 3 As shown, the plastic waste washing device also includes a liquid extraction mechanism 700. The inlet end of the liquid extraction mechanism 700 is connected to the washing tank 100, and the outlet end of the liquid extraction mechanism 700 is connected to the tank body or the outside. The plastic waste washing device also includes a filtration mechanism 800, through which the tank body is connected to the outside. The filtration mechanism 800 is used to filter the liquid contained in the tank, facilitating the reuse of the liquid in the tank.

[0033] In this embodiment, the liquid extraction mechanism 700 includes a third conduit 710 and a third pump body 720. The first pool 400 is also connected to the cleaning tank 100 through the third conduit 710, and the third pump body 720 is installed in the third conduit 710. The liquid extraction mechanism 700 also includes a fourth conduit 730 and a fourth pump body 740. The second pool 500 is also connected to the cleaning tank 100 through the fourth conduit 730, and the fourth pump body 740 is installed in the fourth conduit 730. At one end of the cleaning tank 100, both the third conduit 710 and the fourth conduit 730 are inserted into the cleaning tank 100 from the discharge port 120, enabling rapid liquid extraction. It should be noted that the third conduit 710 can also be connected to the cleaning tank 100 through the fourth conduit 730.

[0034] In this embodiment, the filtration mechanism 800 can be a circular vibrating screen. Both the first pool body 400 and the second pool body 500 are equipped with circular vibrating screens, which can be used to filter and discharge slag from the liquid drawn back into the pool body, facilitating the reuse of the liquid in the pool body.

[0035] It should be noted that liquid level sensors can also be installed in the first pool 400 and the second pool 500. When the liquid level sensor detects that the liquid level in the first pool 400 and the second pool 500 is lower than the threshold, the liquid in the first pool 400 and the second pool 500 can be replenished.

[0036] The working principle of the plastic crushing and washing device in this embodiment is as follows: After cleaning the plastic shreds, the third pump 720 is turned on so that the cleaning agent in the cleaning tank 100 can be drawn back into the first tank 400 through the third conduit 710. Then, the filtration mechanism 800 is started to filter and discharge the slag in the first tank 400. The cleaning agent in the first tank 400 after filtration can be reused. It should be noted that when the third pump 720 is turned on to draw back the cleaning agent, the rotating mechanism 200 can continue to operate. During the rotation of the hopper 300, the residual cleaning agent on the plastic shreds can be removed. After rinsing the crushed plastic material, the fourth pump 740 is turned on so that the liquid in the washing tank 100 can be drawn back into the second tank 500 through the fourth conduit 730. Then, the filtration mechanism 800 is started to filter and discharge the slag in the second tank 500. The water in the second tank 500 after filtration can be reused. It should be noted that when the fourth pump 740 is turned on to draw back the liquid, the rotating mechanism 200 can continue to operate. During the rotation of the hopper 300, the residual liquid on the crushed plastic material can be removed.

[0037] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
