Description

Technical Field

[0001] This application relates to the field of plastic processing equipment technology, specifically to a plastic processing apparatus with cleaning and drying functions. Background Technology

[0002] In the field of plastic recycling and processing, cleaning and drying of plastic granules are two indispensable pre-treatment steps. Currently, the industry generally uses separate equipment for processing: first, the plastic granules are cleaned in a washing machine to remove surface stains and impurities, and then the wet plastic granules are manually transferred to dedicated drying equipment (such as hot air dryers or drum dryers) for dehydration and drying. This separate operation mode has significant drawbacks: first, it has limited functionality, high equipment investment costs, and large space requirements; second, it relies on manual transfer, which is not only labor-intensive and inefficient, but also prone to material spillage and secondary pollution during the transfer process; in addition, traditional methods such as hot air drying suffer from large heat loss and uneven heating, resulting in lower drying efficiency and effectiveness. Therefore, there is an urgent need for a high-efficiency plastic processing device that integrates cleaning and drying and can achieve automated operation. Summary of the Invention

[0003] To address the limitation of existing plastic granule drying devices in terms of functionality, this application provides a plastic processing apparatus with both cleaning and drying functions. The specific technical solution of this application is as follows:

[0004] A plastic processing apparatus with cleaning and drying functions includes: a drying mechanism, a cleaning mechanism, and a conveying mechanism disposed between the drying mechanism and the cleaning mechanism. The drying mechanism includes a support frame, a roller, a heating plate, and a power component. The support frame is disposed on both sides of the roller, and the roller is rotatably mounted on the support frame. The heating plate is disposed in the roller, and its two ends are fixedly mounted to the support frame. The power component includes a first drive motor and a drive chain. The drive chain is sleeved on the outer wall of the roller, and the first drive motor is disposed outside the roller and drivenly connected to the drive chain. The cleaning mechanism includes a cleaning tank and a plurality of cleaning rollers. The cleaning rollers are arranged in the cleaning tank, and their two sides are connected to the inner wall of the cleaning tank. A plurality of actuating plates are disposed on the cleaning rollers, and the actuating plates are arranged around the cleaning rollers. The conveying mechanism includes a conveying cylinder, a spiral shaft, and a second drive motor. One end of the conveying cylinder is disposed in the cleaning tank, and the other end is connected to the roller through the support frame. The spiral shaft is disposed in the conveying cylinder, and the second drive motor is disposed on the conveying cylinder and drivenly connected to the spiral shaft. The spiral shaft is provided with spiral blades.

[0005] Furthermore, the support frame is provided with a baffle for closing the roller. The upper end of the baffle on the side of the support frame connected to the conveying cylinder is provided with a feed inlet, and the top of the conveying cylinder is located at the feed inlet. The lower end of the baffle on the other side of the support frame is provided with a discharge outlet.

[0006] Furthermore, a movable door is provided at the discharge port, and a cylinder is provided above the movable door, with the piston rod of the cylinder mechanically connected to the movable door.

[0007] Furthermore, the baffle is provided with a limiting groove on one side of the roller, and the edge of the opening of the roller is disposed in the limiting groove.

[0029] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of this application, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting it.

[0030] like Figures 1 to 6 As shown, this application relates to a plastic processing apparatus with cleaning and drying functions, including: a drying mechanism 1, a cleaning mechanism 2, and a conveying mechanism 3 disposed between the drying mechanism 1 and the cleaning mechanism 2. These three parts together constitute a complete plastic processing system.

[0031] The drying mechanism 1 includes a support frame 4, a roller 5, a heating plate 6, and a power assembly 7. The support frame 4 is disposed on both sides of the roller 5, providing stable support for the roller 5. The roller 5 is rotatably mounted on the support frame 4 to achieve rotational movement. The heating plate 6 is disposed inside the roller 5, with its two ends fixed to the support frame 4 to ensure heating stability. The power assembly 7 includes a first drive motor 8 and a drive chain 9. The drive chain 9 is sleeved on the outer wall of the roller 5. The first drive motor 8 is disposed outside the roller 5 and is connected to the drive chain 9 via a sprocket on its output shaft, providing rotational power to the roller 5. The heating plate 6 penetrates the roller 5, heating all the plastic granules in the roller 5, resulting in better heating effect compared to hot air heating. The rotating roller 5 ensures more uniform heating of the plastic granules within it.

[0032] The cleaning mechanism 2 includes a cleaning tank 10 and several cleaning rollers 11. The cleaning rollers 11 are arranged in parallel in the cleaning tank 10, and their two axial ends are connected to the inner wall of the cleaning tank 10 via bearings, allowing them to rotate freely. Several agitator plates 12 are provided on each cleaning roller 11, arranged in a spiral or radial pattern around the axis of the cleaning roller 11, for stirring the cleaning liquid and plastic particles. The cleaning tank 10 contains cleaning liquid, the density of which can be adjusted by adding cleaning agents or salt, allowing plastic particles of different densities to float in the cleaning liquid. The several cleaning rollers 11 divide the cleaning tank 10 into different areas. Plastic particles floating in the cleaning liquid are pushed from the surface of the cleaning liquid into the cleaning liquid by the agitator plates of the cleaning rollers 11, and pass under the cleaning rollers 11 to move to the next cleaning area. The plastic particles sequentially pass through all the cleaning areas and then move to the feed inlet of the conveying mechanism 3. This cleaning structure effectively improves the cleaning efficiency of plastic particles.

[0033] The conveying mechanism 3 includes a conveying cylinder 13, a spiral shaft 14, and a second drive motor 15. One end of the conveying cylinder 13 is set in the washing tank 10 to receive the washed material, and the other end is connected to the drum 5 through the support frame 4 to realize the continuous conveying of the material. The spiral shaft 14 is set in the conveying cylinder 13 as the main conveying component. The second drive motor 15 is set on the conveying cylinder 13 and is connected to the spiral shaft 14 through a coupling to provide conveying power. The spiral shaft 14 is provided with continuous integral spiral blades 16 to push the material from the washing tank into the drum.

[0034] In one embodiment, the support frame 4 is provided with circular baffles 17 for closing both ends of the roller 5. The upper end of the baffle 17 on the side of the support frame 4 connected to the conveying cylinder 13 is provided with a square feed port 18. The top discharge port of the conveying cylinder 13 is located at the feed port 18 to achieve seamless connection. The lower end of the baffle 17 on the other side of the support frame 4 is provided with a discharge port 19 for discharging the dried material.

[0035] In one embodiment, an openable and closable movable door 20 is provided at the discharge port 19. A control cylinder 21 is provided above the movable door 20. The piston rod of the cylinder 21 is mechanically connected to the movable door 20 through a linkage mechanism. Under the action of the cylinder 21, the movable door 20 is automatically opened or closed to realize automatic material discharge.

[0036] In one embodiment, the baffle 17 has an annular limiting groove 22 machined on one side of the roller 5. The edge of the opening of the roller 5 is set in the limiting groove 22. The limiting groove 22 can provide support for the rotation of the roller. A bearing can also be set between the limiting groove and the roller 5 to improve the rotation of the roller 5.

[0037] In one embodiment, the drum 5 is provided with a detachable filter cylinder 23 inside. An annular receiving layer 24 is provided between the filter cylinder 23 and the inner wall of the drum 5 for collecting fine particles. The body of the filter cylinder 23 is uniformly provided with a number of elongated filter holes 25. Fine particles on the plastic particles will enter the receiving layer 24 through the filter holes 25.

[0038] In one embodiment, the inner wall of the filter cylinder 23 is provided with a continuous spiral guide plate 26, which pushes the material forward when the drum 5 rotates, thereby improving the drying efficiency.

[0039] In one embodiment, four heating plates 6 are evenly arranged in the drum 5. These heating plates 6 are circumferentially distributed and sequentially connected inside the filter cylinder 23, forming a complete heating ring. The heating plates 6 are infrared heating plates, or they can be composed of an ultraviolet lamp and an infrared heating plate arranged sequentially. This allows for heating and sterilization of the plastic granules. When ultraviolet lamps are used, to prevent harm to the human body, if the discharge port 19 of the drum 5 is blocked by the movable door 20, the inlet 18 of the drum 5 needs to be covered with an opaque board or cloth.

[0040] In one embodiment, the power assembly 7 further includes a guide seat 27 and a guide ring 28. The guide ring 28 is fastened to the outer wall of the roller 5, and the guide seat 27 is located at the bottom support position of the roller 5. The guide seat 27 and the guide ring 28 are connected by contact to provide auxiliary support and rolling guidance.

[0041] In one embodiment, the cleaning roller 11 is fitted with a porous connecting cylinder 29, and the connecting cylinder 29 is evenly provided with a plurality of through holes 30. The through holes can agitate the water flow and enhance the cleaning effect. The agitator plate 12 is welded or bolted to the outer surface of the connecting cylinder 29.

[0042] In one embodiment, the spiral blade 16 is provided with a water leakage hole 31, which can prevent the spiral blade 16 from bringing too much water into the drum 5.
