Description

Technical Field

[0001] This utility model relates to the field of plastic recycling and processing, and in particular to a plastic granule washing machine. Background Technology

[0002] Plastic recycling refers to the process of recycling waste plastics using specific recycling technologies to achieve the goal of turning waste into treasure. Currently, waste plastics in my country mainly consist of plastic films, plastic filaments and woven products, foam plastics, plastic packaging boxes and containers, daily-use plastic products, plastic bags, and agricultural mulch films. With the continuous increase in the consumption of plastic products, the amount of waste plastics is also constantly increasing, making the recycling and reuse of waste plastics increasingly important.

[0003] Because waste plastics typically have a lot of dirt adhering to them, they need to be crushed into granules and then washed before recycling to improve the quality of the recycled plastics. However, existing plastic washing machines consume a lot of water, resulting in high washing costs and wasting resources. In addition, they do not agitate the materials enough, leading to poor washing results and low efficiency in plastic cleaning. Furthermore, because plastic washing and recycling machines are quite bulky, they require a crane to move them, making them inconvenient to use. Utility Model Content

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

[0006] This utility model discloses a plastic granule cleaning machine, comprising a cleaning machine body; at least two brushes for cleaning plastic granules are longitudinally arranged in the cavity of the cleaning machine body, the brushes are located in the lower part of the cavity of the cleaning machine body, and the brushes are rotatably mounted on the side walls of the cleaning machine body via brush shafts; a spiral blade shaft is also provided in the cavity of the cleaning machine body, the spiral blade shaft being arranged parallel to the brush shaft; a servo motor for driving the spiral blade shaft to rotate is provided at the bottom of the cleaning machine body, the servo motor being connected to one end of the spiral blade shaft via a chain, and several brush shafts being connected to the spiral blade shaft via chains; a spraying mechanism is provided above the cleaning machine body, the spraying mechanism including a cleaning agent pipe, a compressed air pipe, and several atomizers fixed to the top of the cleaning machine body; a discharge port is also provided on the side of the cleaning machine body; a discharge lever is connected to the cleaning machine body corresponding to the discharge port.

[0007] As a preferred embodiment of this utility model, a filter screen is provided at the bottom of the cavity of the cleaning machine body.

[0009] As a preferred technical solution of this utility model, the number of brushes is six, each brush is horizontally arranged, and several bristles are evenly distributed on the brush, with the length of the bristles gradually changing to form a wave shape. Both ends of each brush shaft are rotatably connected to the inner wall of the cleaning machine body through bearings. The servo motor drives the brush shaft to rotate for flipping the plastic particles.

[0010] As a preferred embodiment of this utility model, a plurality of atomizers are equidistantly distributed along the cleaning agent pipeline.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] like Figure 1-5As shown, this utility model provides a plastic granule cleaning machine, including a cleaning machine body 1; at least two brushes 2 for cleaning plastic granules are longitudinally arranged in the cavity of the cleaning machine body 1, the brushes 2 are located in the lower part of the cavity of the cleaning machine body 1, and the brushes 2 are rotatably mounted on the two side walls of the cleaning machine body 1 via brush shafts 3; a spiral blade shaft 4 is also provided in the cavity of the cleaning machine body 1, the spiral blade shaft 4 is arranged parallel to the brush shaft 3; a servo motor 5 for driving the spiral blade shaft 4 to rotate is provided at the bottom of the cleaning machine body 1, the servo motor 5 is connected to one end of the spiral blade shaft 4 via a chain 6, and several brush shafts 3 are connected to the spiral blade shaft 4 via chains; a spraying mechanism 7 is provided above the cleaning machine body 1;

[0027] The spraying mechanism 7 includes a cleaning agent pipe 8, a compressed air pipe 9 and several atomizers 10 fixed to the top of the cleaning machine body 1; a discharge port 11 is also provided on the side of the cleaning machine body 1; a discharge lever 12 is connected to the cleaning machine body 1 at the corresponding discharge port 11.

[0028] In this embodiment, the servo motor 5 drives the spiral blade shaft 4 to rotate via the chain 6, which in turn drives the brush shaft 3 to rotate, thereby continuously tumbling and agitating the plastic particles inside the cavity of the cleaning machine body 1. Combined with the atomizing cleaning by the atomizer 10, impurities and dust on the plastic surface are effectively removed. Preferably, four rollers are also installed at the bottom of the cleaning machine body 1 to facilitate the movement of the cleaning machine.

[0029] For further details, please refer to the appendix. Figure 4 The bottom of the cavity of the cleaning machine body 1 is provided with a filter screen 13. The filter screen 13 is a cuboid and its two ends are fixed to the inner wall of the cleaning machine body 1. The filter screen 13 has a number of filter screen holes evenly distributed on it. The diameter of the filter screen holes is smaller than the diameter of the plastic particles. The waste liquid and impurities after the plastic particles are cleaned flow onto the filter screen 13 under the action of gravity and are discharged downward from the filter screen holes.

[0030] Furthermore, a waste liquid hopper 14 is provided below the filter screen 13. A waste liquid discharge pipe 15 is provided at the bottom of the waste liquid hopper 14. The two sides of the waste liquid hopper 14 are welded to the inner wall of the cleaning machine body 1. The waste liquid and impurities flowing out from the filter screen 13 are collected in the waste liquid hopper 14 and then discharged through the waste liquid discharge pipe 15.

[0031] For further details, please refer to the appendix. Figure 3-5 There are six brushes 2, each brush 2 is set horizontally, and several bristles are evenly distributed on the brush 2. The length of the bristles gradually changes to form a wave shape. Both ends of the brush shaft 3 are rotatably connected to the inner wall of the cleaning machine body 1 through bearings. By rotating the brush shaft 3, the bristles attached to the brush 2 are driven to rotate, which is used to flip the plastic particles.

[0032] In this embodiment, the spiral blade shaft 4 drives the brush shaft 3 to rotate via a chain connection. The brush shaft 3 drives the brush 2 to rotate continuously within the cleaning machine body. The six brush shafts 3 rotate continuously in opposite directions. The wavy bristles attached to the brush 2 continuously tumble and agitate the material. The plastic particles continuously jump, collide, and rub under the agitation of the bristles. Then, the surface of the plastic particles is cleaned by the spray mechanism, thereby effectively removing impurities and dust from the plastic surface and improving cleaning efficiency.

[0033] Furthermore, several atomizers 10 are equidistantly distributed along the cleaning agent pipeline 8. The water inlet of the atomizer 10 is connected to the cleaning agent pipeline 8, and the air inlet of the atomizer 10 is connected to the compressed air pipeline 9. The other end of the compressed air pipeline 9 is connected to an air compressor to provide compressed air to the atomizer 10. The atomizer 10 is vertically downward equipped with an atomizing nozzle 16, which is trumpet-shaped and used to spray atomized cleaning agent into the cavity of the cleaning machine body 1.

[0034] In this embodiment, the other end of the cleaning agent pipe 8 is connected to a cleaning agent tank. The atomizer 10 receives the cleaning agent from the cleaning agent pipe 8 and the compressed air from the compressed air pipe 9. After atomizing the cleaning agent, it is sprayed downwards evenly onto the surface of the plastic particles to increase the contact area between the cleaning agent and the plastic particles and improve the cleaning effect.

[0035] For further details, please refer to the appendix. Figure 4 The spiral blade shaft 4 is provided with several spiral blades 17, which are distributed end to end along the spiral blade shaft 4. They are used to flip the plastic granules and push them toward the discharge port 11. The two ends of the spiral blade shaft 4 are rotatably connected to the inner wall of the washing machine body 1 through bearing seats.

[0036] In this embodiment, the servo motor 5 drives the spiral blade shaft 4 to rotate via the chain 6. The spiral blade 17 continuously flips under the drive of the spiral blade shaft 4. While pushing the material forward, the spiral blade 17 also flips and agitates the material. Combined with the mist cleaning agent sprayed by the atomizer 10, the material is conveyed and cleaned at the same time. This cleaning method has high production efficiency, and the material is continuously flipped and rubbed by the spiral blade 17 in the cleaning machine, resulting in a good cleaning effect.

[0037] For further details, please refer to Figure 1-2 The discharge paddle 12 is slidably connected to the discharge port 11. The end of the discharge paddle 12 is fixed with a paddle handle 18. The discharge paddle 12 can be pulled out from the washing machine body through the paddle handle 18, thereby opening the discharge port 11 and allowing plastic particles to pass through. Guide plates 19 are provided on both sides of the discharge port 11. The guide plates 19 are semi-circular. The front end of the guide plate 19 is connected to the end of the spiral blade 17 for guiding the output of the washed plastic particles.

[0038] In this embodiment, after the plastic particles are cleaned, the previously closed discharge paddle 12 can be pulled out through the paddle handle 18 to open the discharge port 11. The cleaned plastic particles are discharged along the guide plate 19 under the driving action of the spiral blade 17, thus completing the thorough cleaning of the plastic particles.

[0039] This invention relates to a plastic granule washing machine. A brush shaft drives the brush to rotate continuously within the machine body. Simultaneously, a spiral blade shaft drives the spiral blades to rotate, which both pushes and agitates the material, resulting in strong friction between the material and the brush bristles and a thorough cleaning. Furthermore, an atomizer atomizes the cleaning agent, continuously impacting the plastic surface, enhancing the cleaning effect while conserving water.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
