The output shaft of the second single-shaft cylinder 29 is fixedly connected to the bottom end of the rectangular slide bar. A connecting frame 30 is fixedly installed at the top of the rectangular slide bar. A rotary motor 31 is fixedly installed inside the connecting frame 30. A connecting shaft 32 is rotatably installed at the top of the connecting frame 30. The output shaft of the rotary motor 31 is fixedly connected to the connecting shaft 32. A cover 33 is fixedly installed at the top of the connecting shaft 32, and a second sealing ring is fixedly installed at the bottom of the cover 33. The bottom of the second sealing ring abuts against the top end face of the dehydration barrel 5. The output shaft of the second single-shaft cylinder 29 extends to separate the second sealing ring from the top of the dehydration barrel 5. Then, by running the rotary motor 31, the cover 33 is driven to rotate, so that it moves away from the top of the dehydration barrel 5, and the hollow rotating barrel 6 can be taken out from the dehydration barrel 5.

[0053] In this embodiment, in order to collect the water spun out during the dehydration process, a drain pipe is fixedly installed at the bottom of the dehydration bucket 5, and a fourth electric valve is provided on the drain pipe. A third collection box 34 is fixedly installed on the top of the machine base 1, and the drain pipe is located above the third collection box 34. A third filter screen is fixedly installed inside the third collection box 34.

[0054] The first collection box 8, the second collection box 24 and the third collection box 34 are all equipped with drainage pipes, and the drainage pipes eventually flow into the external wastewater pool to facilitate the subsequent purification and reuse of the wastewater.

[0055] In this embodiment

[0056] In the initial state, the output shaft of the first single-shaft cylinder 13 is extended; and the water inlet of the water pump 17 is connected to the external clean water tank through an external pipe. Before use, the second electric valve on the first drain pipe 18 is opened and the water pump 17 is started. The water pump 17 pumps clean water into the hot alkali tank 4. After pumping to a certain amount, according to the ratio, alkaline substances are added into the hot alkali tank 4 through the second feeding pipe, and the third drive motor is started. The alkaline solution is shaken evenly by the spiral blades. At the same time, the arc heating pad 402 is started to heat the alkali solution, and the temperature of the alkali solution is obtained through the temperature sensing element 403. Once the temperature reaches the required range, the second electric valve on the first drain pipe 18 is closed.

[0057] When processing plastic, the plastic to be processed is first poured into the crushing chamber 3 through the feed port, and then guided by the guide plate to the space between two opposing crushing rollers 301. Then, driven by the first drive motor, the two crushing rollers 301 are synchronously operated through the meshing of the two first gears, and the plastic is crushed into small particles.

[0058] The crushed particles smoothly enter the friction cleaning chamber 2 through the discharge port and the feed hopper of the friction cleaning chamber 2. At this time, the sealing unit is in a closed state to prevent material leakage.

[0059] Then, the second drive motor is started, and the transmission sleeve 201 is rotated through the cooperation of the two second gears, driving the hollow disc 202 and the stirring rod 204 to rotate synchronously. At the same time, the third electric valve on the second drain pipe 19 is opened, and the water pump 17 is started. The water pump 17 draws clean water and passes it into the heat exchange coil 20. At this time, the clean water can absorb some of the heat from the hot alkali tank 4, thereby raising the temperature of the clean water to a warm state. The warm clean water enters the hollow disc 202 through the connecting pipe 21 and is finally sprayed out through the spray hole 203. At the same time, detergent is added into the friction cleaning chamber 2 through the first feeding pipe. At this time, the stains attached to the surface of the plastic are peeled off under the stirring of the stirring rod 204 and the combined action of the friction protrusion 205. During the washing process, the first electric valve on the liquid guide pipe 704 can be opened to allow the wastewater to be smoothly discharged into the first collection tank 8 and filtered through the first filter screen.

[0060] After the initial cleaning is completed, the rodless cylinder 7 is started, and the slider on it moves the dual-shaft cylinder 701 horizontally, so that the sealing plate 703 is gradually removed from the opening at the bottom of the friction cleaning chamber 2. At this time, the cleaned plastic will directly enter the first screw feeder 9 through the first injection hopper and be conveyed. During the conveying process, some residual water on the plastic will continue to be discharged through the first seepage hole 10 and fall into the first collection box 8. Finally, it will enter the hot alkali tank 4 through the first discharge pipe. At the same time, the third drive motor is started to drive the stirring rod 16 to rotate, so that the plastic can roll and rotate in the alkali solution, which can promote the full contact between the plastic and the alkali solution and dissolve oily contaminants.

[0061] After hot alkali degreasing is completed, first, the output shaft of the second single-shaft cylinder 29 is extended to separate the cover 33 from the dehydration tank 5. Then, the rotary motor 31 is started in the forward direction, and the cover 33 is rotated by the connecting shaft 32 until it rotates 90°. Subsequently, the output shaft of the first single-shaft cylinder 13 is retracted, and the sealing box 14 will rotate on the axis hinged between itself and the adapter 12, thereby opening the bottom of the hot alkali tank 4. The plastic and alkali solution are discharged together and enter the second spiral feeder through the second hopper. Similarly, inside the feeder 22, the design of the second seepage hole 23 allows for the initial dehydration of the plastic. The seeping liquid falls directly into the second collection box 24 and is filtered by the second filter screen. After the initial dehydration, the plastic enters the hollow rotating drum 6 through the second discharge pipe. After all the plastic has entered, the rotating motor 31 is started in reverse to rotate the cover 33 back to its original position. Then, the output shaft of the second single-shaft cylinder 29 is retracted, and the top of the dehydration drum 5 is sealed again using the cover 33.

[0062] Then, open the fourth electric valve below the dehydration tank 5 and start the waterproof motor. Driven by the rotating shaft 502, the hollow rotating tank 6 starts to rotate rapidly. Centrifugal force causes water to be discharged through the hollow structure and flow into the third collection box 34 for filtration by the third filter screen.

[0063] After dehydration, unscrew the bolts on the horizontal slide rail 25 to separate it from the sliding base 26. Then, pull the dehydration barrel 5 horizontally and pull it away from under the second screw feeder 22. After pulling it to the final position, the mounting holes on the sliding base 26 correspond to the three threaded holes in another set. Then, tighten the bolts to fix it. After that, open the cover 33 again, and then separate the hollow rotating barrel 6 from the fixing ring 505. Then, take the hollow rotating barrel 6 out of the dehydration barrel 5 and pour in the dehydrated plastic.

[0064] Compared with related technologies, the integrated plastic recycling, washing, and dehydration machine provided by this invention has the following beneficial effects:

[0065] I. This invention achieves integrated operation of plastic crushing, washing, degreasing and dehydration through the modular design of crushing chamber 3, friction cleaning chamber 2, hot alkali tank 4 and dehydration tank 5, reducing material transfer links, reducing labor costs and improving processing efficiency to a great extent.

[0066] Second, the present invention utilizes the synergistic effect of the hollow disc 202 and the stirring rod 204 inside the friction cleaning chamber 2, along with the friction protrusions 205 to enhance physical friction, so that the plastics collide and rub against each other, and at the same time, the plastics and the friction protrusions 205 also rub against each other, thereby effectively removing stubborn stains; in addition, the hot alkaline solution in the hot alkaline pool 4 can degrease the plastics, further improving the cleaning effect.

[0067] Third, the present invention utilizes the heat of the hot alkali tank 4 itself to heat the clean water entering the friction cleaning chamber 2 using the heat exchange coil 20. On the one hand, this can improve energy utilization and achieve energy-saving effect. On the other hand, the warm clean water can improve the solubility of detergent, thereby improving the cleaning effect on plastics.

[0068] Second embodiment:

[0069] Based on the integrated plastic recycling, washing, and dewatering machine provided in the first embodiment of this application, the second embodiment of this application proposes another integrated plastic recycling, washing, and dewatering machine. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0070] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0071] Please refer to the following: Figures 18-21In the second embodiment of the plastic recycling, washing, and dehydration integrated machine provided by the present invention: two connecting shafts 28 are respectively rotatably mounted on two mounting brackets 27. A transmission shaft 35 is fixedly mounted on the end of one connecting shaft 28 away from the dehydration tank 5. A curved through groove 36 is opened on the transmission shaft 35. A third single-shaft cylinder 37 is fixedly mounted on the corresponding mounting bracket 27. A push rod 38 is fixedly mounted on its output shaft. The push rod 38 passes through the curved through groove 36 and fits against the inner wall of the curved through groove 36. Through the linear movement of the push rod 38, the transmission shaft 35 can be rotated by the sliding fit between it and the curved through groove 36, thereby driving the connecting shaft 28 and the dehydration tank 5 to rotate. A base is fixedly mounted on one side of the machine base 1. A drying chamber 39 is fixedly mounted on the base. Shuttle openings are opened on both sides of the drying chamber 39. Two back plates 40 are fixedly mounted on the outer walls of both sides of the drying chamber 39. Conveyor rollers are rotatably mounted on the corresponding two back plates 40. 41. Two conveyor rollers 41 are fitted with the same conveyor belt 42. The conveyor belt 42 has multiple ventilation holes. A conveyor motor is fixedly installed on one of the back plates 40, and its output shaft is fixedly connected to the end of the corresponding conveyor roller 41. A ventilation pipe 43 is fixedly installed in the drying chamber 39. The ventilation pipe 43 is located above the conveyor belt 42. Three air nozzles 44 are fixedly installed at the bottom of the ventilation pipe 43. A hot air blower 45 is fixedly installed on the top of the drying chamber 39. The air outlet of the hot air blower 45 extends into the drying chamber 39 and is fixedly connected to the ventilation pipe 43. A guide channel steel is fixedly installed on the top of the base. The guide channel steel is located below the side of the conveyor belt 42 away from the machine base 1. First, the push rod 38 is moved by the third single-shaft cylinder 37, so that the top opening of the dehydration barrel 5 is tilted downward. Then, the cover 33 is opened, so that the plastic in the hollow rotating barrel 6 is naturally discharged and falls onto the conveyor belt 42 for automatic conveying. Then, it enters the drying chamber 39 for final drying treatment and is finally discharged.

[0072] In this embodiment

[0073] After the plastic is dehydrated, in order to further improve the dehydration effect and automatically discharge the plastic, a storage box is first placed under the guide channel steel, and then the dehydration bucket 5 is pulled away from under the second screw feeder 22 and fixed.

[0074] Then, the hot air blower 45 is started, and hot air is blown into the drying chamber 39 through the nozzle 44. The output shaft of the third single-shaft cylinder 37 is started to extend, and the push rod 38 begins to move linearly. Affected by the curved through groove 36, the transmission shaft 35 rotates with the corresponding connecting shaft 28, and then rotates the dehydration drum 5. After the push rod 38 extends to the final position, the top opening of the dehydration drum 5 is tilted downward. Then the output shaft of the second single-shaft cylinder 29 is started to extend, and the rotary motor 31 is started to open the cover 33.

[0075] The plastic inside the hollow rotating drum 6 will automatically roll onto the conveyor belt 42. At this time, the conveyor belt 42 will transport the plastic to the drying chamber 39. The hot air sprayed from the nozzle 44 can dry the plastic. The ventilation holes on the conveyor belt 42 can improve the overall drying effect. After drying, the plastic will be discharged into the storage box through the guide trough. After the discharge is completed, the cover 33 will be reset first, and then the output shaft of the third single-axis cylinder 37 will be retracted to rotate the dehydration drum 5 back to its original state.

[0076] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
