Technical Field
[0001] This invention relates to the field of plastic recycling technology, and in particular to a plastic pellet washing device. Background Technology
[0002] Plastics are difficult to degrade in the natural environment. Landfilling will occupy a lot of land resources and may release toxic substances that pollute the soil and groundwater. Incineration will produce toxic and harmful gases that pollute the environment. With the development of the economy and society, plastic products are used extensively in people's production and life. The plastic content in household waste is constantly increasing, and the recycling and resource utilization of waste plastics has gradually become a hot issue.
[0003] In plastic recycling, cleaning plastic granules is a crucial step in the recycling and reprocessing process. During recycling, plastic surfaces become contaminated with pollutants such as dust, oil, impurities, and residual chemicals. Cleaning removes these pollutants, improving the quality of the plastic granules and enabling the recycled plastic to meet the requirements of subsequent processing and manufacturing.
[0004] Currently, the most common cleaning method is to put the plastic particles to be cleaned into the cleaning tank at once and use mechanical equipment to remove the dirt on the surface of the plastic particles through stirring and friction. However, this method will cause a large number of plastic particles to accumulate in the treatment tank. Due to the limited cleaning space and cleaning capacity, a large number of plastic particles are concentrated together, blocking and accumulating each other, making it difficult for some particles to fully contact the cleaning medium. It is difficult to ensure that each batch of plastic particles can be cleaned fully and effectively, which seriously reduces the cleaning effect. Summary of the Invention

[0023] The technical effects and advantages of this invention are as follows:
[0024] In this invention, when the first drive motor drives the intermittent feeding cylinder to rotate, a series of transmission components such as the first transmission shaft, the first transmission belt, and the second transmission shaft ultimately drive the transmission disc to rotate. The push rod on the transmission disc pushes the transmission frame to move back and forth, thereby pulling the connecting frame to move. During the movement of the connecting frame, the guide groove plays a key role. When the connecting frame moves towards the direction of the transmission component, under the guidance of the guide groove, the scrubbing sponge moves slightly upward and no longer contacts the plastic particles, making it convenient for the intermittent feeding cylinder to pour new plastic particles onto the fixed scrubbing plate and let them slide into the scrubbing space. When the transmission disc pushes the transmission frame to move towards the processing box, the connecting frame moves downward and resets, and the scrubbing sponge scrubs the plastic particles. At the same time, in conjunction with the downward tilting movement, the plastic particles are further conveyed downward, realizing an efficient and orderly scrubbing process.
[0025] After being cleaned by the scrubbing assembly, the plastic granules fall into the rinsing frame. The second drive motor drives the third transmission shaft to rotate, which in turn causes the two sets of drive discs to rotate simultaneously via the second transmission belt. The drive rods on the drive discs push the drive frame up and down, thereby pulling the rinsing frame up and down continuously within the rinsing tank. This up-and-down movement allows water from the rinsing tank to continuously enter the rinsing frame, thoroughly rinsing off the detergent from the surface of the plastic granules. This effectively removes residual impurities and chemicals from the plastic granules, further improving their cleanliness. Simultaneously, during the up-and-down movement, the plastic granules within the rinsing frame tumble and redistribute with the water flow and the frame's movement, ensuring that each plastic granule has the opportunity to fully contact the water flow and guaranteeing that all plastic granules receive uniform rinsing treatment.
[0026] In this invention, precise feeding is achieved through an intermittent feeding structure. The first drive motor is started to drive the intermittent feeding cylinder to rotate. When its opening rotates to the top, the plastic particles in the feeding box fall into it, and then fall onto the scrubbing component of the processing box as it rotates. This intermittent feeding method allows the plastic particles in the storage box to be added to the processing box in small amounts and multiple times, avoiding the problem of insufficient cleaning caused by a large amount of material added at once. This ensures that each batch of plastic particles can be thoroughly and effectively cleaned, greatly improving the cleaning effect. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.
[0038] Reference Figure 1-9 As shown, the present invention provides a technical solution for a plastic particle washing device:
[0039] A plastic granule cleaning device includes a support base 1, a plastic granule processing component 2 fixedly connected to the top of the support base 1, a cleaning mechanism for cleaning plastic granules in the plastic granule processing component 2, a feeding component 3 for guiding plastic granules into the plastic granule processing component 2 fixedly connected to the top of the plastic granule processing component 2, a scrubbing component 4 disposed in the plastic granule processing component 2, a transmission component 5 disposed on the side of the plastic granule processing component 2 near the feeding component 3, one end of the transmission component 5 being connected to the feeding component 3, and the other end passing through the plastic granule processing component 2 and connected to the scrubbing component 4 in the plastic granule processing component 2, the cleaning mechanism also includes a rinsing component 6 disposed below the scrubbing component 4 for rinsing plastic granules, and two sets of driving components 7 for driving the rinsing component 6 to operate;
[0040] Specifically, when cleaning plastic granules, the plastic granules to be cleaned are first added to the plastic granule processing component 2 through the feeding component 3. When the feeding component 3 is started, the feeding component 3 also drives the transmission component 5 to start, so that the transmission component 5 drives the scrubbing component 4 to move. The added plastic granules are scrubbed by the movement of the scrubbing component 4.
[0041] During the cleaning process, the plastic particles move continuously along the scrubbing assembly 4 and eventually fall into the rinsing assembly 6. The rinsing assembly 6, in conjunction with the drive assembly 7, removes the residual detergent from the plastic particles, making them ready for direct use later.
[0042] In this embodiment: the plastic granule processing component 2 includes a processing box 21, which is fixedly connected to the support base 1. A fixed frame 23 is fixedly connected to the side of the processing box 21 near the feeding component 3. The transmission component 5 is disposed in the fixed frame 23. A cabinet door for picking up materials is also hinged to one side of the processing box 21. A cleaning agent box 24 is also disposed directly below the fixed frame 23. A connecting pipe 25 is connected to the cleaning agent box 24. A conveying piston 26 is also fixedly connected to the fixed frame 23, and the other end of the connecting pipe 25 is connected to the conveying piston 26. A piston rod 27 is slidably connected to the piston 26. A connecting plate 28 is fixedly connected to one end of the piston rod 27 away from the conveying piston 26. The other end of the connecting plate 28 is fixed to the transmission component 5 inside the fixed frame 23. Multiple sets of nozzles 22 are fixedly connected to the inner wall of the treatment box 21 near the fixed frame 23. A water supply pipe connected to the multiple sets of nozzles 22 is fixedly connected to the inner wall of the treatment box 21 near the multiple sets of nozzles 22. The inlet end of the water supply pipe is connected to the outlet end of the conveying piston 26. The spraying direction of the multiple sets of nozzles 22 is all towards the scrubbing component 4.
[0043] Specifically, during use, after the plastic granules are added to the processing tank 21, the plastic granules first fall onto the scrubbing assembly 4. The feeding assembly 3 drives the transmission assembly 5 to start the scrubbing assembly 4, which scrubs the plastic granules. When the transmission assembly 5 starts, it simultaneously drives the piston rod 27 to slide inside the conveying piston 26. Through the sliding of the piston rod 27, the cleaning agent in the cleaning agent tank 24 is continuously conveyed through the connecting pipe 25 and the conveying piston 26 to the water supply pipe in the processing tank 21, and then conveyed through the water supply pipe to multiple nozzles 22. The cleaning agent is sprayed out through the multiple nozzles 22 and sprayed onto the scrubbing assembly 4. The scrubbing of the scrubbing assembly 4, combined with the cleaning agent, thoroughly cleans the plastic granules.
[0044] After being rubbed, the plastic particles fall into the rinsing assembly 6. The rinsing assembly 6 and the drive assembly 7 work together to rinse out the detergent from the plastic particles. Then, open the cabinet door on the processing box 21 and take out the rinsed plastic particles.
[0045] In this embodiment: the feeding assembly 3 includes a storage box 31, which is fixedly connected to the processing box 21. A feeding box 32 is fixedly connected to the discharge end of the storage box 31 and is fixedly connected to the inner wall of the top of the processing box 21. An intermittent feeding cylinder 33 is rotatably connected to the feeding box 32. A first drive motor 34 is also fixedly connected to one side of the feeding box 32, and the output end of the first drive motor 34 is fixedly connected to the intermittent feeding cylinder 33 via a coupling. A first transmission shaft 35 is fixedly connected to the end of the intermittent feeding cylinder 33 away from the first drive motor 34. A first transmission belt 36 is sleeved on the first transmission shaft 35, and the other end of the first transmission belt 36 is sleeved on the transmission assembly 5. The transmission assembly 5 includes a transmission disc 51, which is rotatably connected to the fixed... In frame 23, the rotating shaft at the bottom of the transmission disc 51 passes through the bottom of the fixed frame 23 and extends to the outside of the fixed frame 23. The extended end of the rotating shaft is fixedly connected to a first bevel gear 52. A second bevel gear 53 is provided on one side of the first bevel gear 52, and the first bevel gear 52 and the second bevel gear 53 mesh. A transmission rod is fixedly connected to the side of the second bevel gear 53 away from the first bevel gear 52, and a second transmission shaft 54 is fixedly connected to the other end of the transmission rod. The end of the first transmission belt 36 away from the first transmission shaft 35 is sleeved on the second transmission shaft 54. The second transmission shaft 54 and the first transmission shaft 35 are connected by transmission through the first transmission belt 36. Multiple sets of fixing brackets 55 are also fixedly connected to the bottom of the fixed frame 23. The side of the multiple sets of fixing brackets 55 near the transmission rod is sleeved on the transmission rod.
[0046] Specifically, during use, a batch of plastic granules to be cleaned is first added to the storage box 31. The plastic granules slide down from the storage box 31 toward the feeding box 32. When cleaning is performed, the first drive motor 34 is started, which drives the intermittent feeding cylinder 33 to rotate. When the opening on the intermittent feeding cylinder 33 rotates to the top, the plastic granules in the feeding box 32 fall into the opening of the intermittent feeding cylinder 33 and fall onto the scrubbing assembly 4 in the processing box 21 as the intermittent feeding cylinder 33 rotates. Through the intermittent feeding of the intermittent feeding cylinder 33, the plastic granules in the storage box 31 can be added to the processing box 21 in small amounts and multiple times, ensuring the cleaning effect of the plastic granules.
[0047] At the same time, when the first drive motor 34 drives the intermittent feeding cylinder 33 to rotate, the first transmission shaft 35 at the other end of the intermittent feeding cylinder 33 also rotates. The first transmission shaft 35 drives the second transmission shaft 54 to rotate through the first transmission belt 36. The second transmission shaft 54 drives the second bevel gear 53 to rotate through the transmission rod, so that the first bevel gear 52 rotates synchronously and drives the transmission disc 51 to rotate. When the transmission disc 51 rotates, it continuously drives the scrubbing component 4 to move and scrub the plastic particles.
[0048] In this embodiment: the scrubbing assembly 4 includes a fixed scrubbing plate 41, which is fixedly connected to the processing box 21 and is slightly inclined. A connecting frame 42 is provided above the fixed scrubbing plate 41. A scrubbing sponge 43 is fixedly connected to the side of the connecting frame 42 near the fixed scrubbing plate 41. The lengths of both the connecting frame 42 and the scrubbing sponge 43 are shorter than the fixed scrubbing plate 41. The side of the connecting frame 42 near the transmission assembly 5 is connected to the transmission assembly 5. Multiple sets of sliding shafts are also fixedly connected to both sides of the connecting frame 42. 44. Multiple sets of upwardly inclined guide grooves 29 are provided on the inner walls of both sides of the treatment box 21. Multiple sets of sliding shafts 44 are slidably connected to adjacent guide grooves 29. Multiple sets of drainage grooves 45 are also provided on the fixed scrubbing plate 41, and the multiple sets of drainage grooves 45 are interconnected. Two sets of connecting pipes 46 are fixedly connected to one side of the fixed scrubbing plate 41. Both sets of connecting pipes 46 are connected to the multiple sets of drainage grooves 45. The ends of the two sets of connecting pipes 46 away from the fixed scrubbing plate 41 pass through the treatment box 21 and extend to the outside of the treatment box 21. Scrubbing assembly 4 also includes a conveyor box 47 fixedly connected to the processing box 21. The conveyor box 47 is located below the fixed washboard 41 and at the end of the fixed washboard 41 away from the feeding assembly 3. The conveyor box 47 is inclined. The discharge end of the conveyor box 47 is located directly above the rinsing assembly 6. The discharge end of the conveyor box 47 is rotatably connected to a closing plate. A push rod 56 is also fixedly connected to the top of the transmission disc 51. The push rod 56 is located at an eccentric position on the transmission disc 51. A transmission frame 57 is sleeved on the push rod 56. Two sets of connecting rods 58 are fixedly connected to the side of the transmission frame 57 near the processing box 21. The ends of the two sets of connecting rods 58 away from the transmission frame 57 pass through the processing box 21 and extend into the processing box 21. The extended ends of the two sets of connecting rods 58 are fixedly connected to connecting blocks 59. The side of the connecting block 59 near the connecting frame 42 is connected to the connecting frame 42, and the connecting frame 42 is slidably connected to the connecting block 59. A synchronizing rod is also fixedly connected to the side of the transmission frame 57 away from the processing box 21, and the other end of the synchronizing rod is fixed to the connecting plate 28.
[0049] Specifically, when the transmission disc 51 rotates, the push rod 56 on the transmission disc 51 simultaneously pushes the transmission frame 57 to move back and forth. When the transmission frame 57 moves, the two sets of connecting rods 58 on the transmission frame 57 simultaneously pull the connecting block 59 to move. The connecting block 59 drives the connecting frame 42 to move. Through the cooperation of the fixed scrubbing board 41, the connecting frame 42 and the scrubbing sponge 43, the plastic particles between the fixed scrubbing board 41 and the scrubbing sponge 43 are scrubbed. At the same time, the wastewater generated by scrubbing is discharged through the drain trough 45 and the connecting pipe 46.
[0050] When the connecting block 59 pulls the connecting frame 42 toward the direction of the transmission component 5, multiple sets of sliding shafts 44 on both sides of the connecting frame 42 slide simultaneously in the guide groove 29. Under the guidance of the guide groove 29, the connecting frame 42 moves obliquely upward, causing the scrubbing sponge 43 to move slightly upward and no longer contact the plastic particles. At this time, the intermittent feeding cylinder 33 pours new plastic particles onto the fixed scrubbing plate 41. The plastic particles slide into the space between the fixed scrubbing plate 41 and the scrubbing sponge 43 along the gap between the scrubbing sponge 43 and the fixed scrubbing plate 41.
[0051] When the transmission disc 51 pushes the transmission frame 57 to move toward the processing box 21, the connecting block 59, driven by the connecting rod 58, pushes the connecting frame 42 to move down and reset, so that the scrubbing sponge 43 scrubs the plastic particles on the fixed scrubbing board 41. At the same time, it moves downward at an angle to further convey the plastic particles downward until the scrubbed plastic particles are introduced into the conveying box 47.
[0052] In this embodiment: the rinsing assembly 6 includes a rinsing tank 61 fixedly connected to the processing tank 21. The rinsing tank 61 is located directly below the conveying tank 47. A rinsing frame 62 is provided in the rinsing tank 61, and two sets of drive assemblies 7 are located on one side of the rinsing tank 61. Two sets of connecting plates 63 are fixedly connected to the top of the rinsing frame 62 near the drive assembly 7. The tops of the two sets of connecting plates 63 are respectively fixed to the adjacent drive assembly 7. A drain pipe 64 for draining water is also fixedly connected to one side of the rinsing tank 61. The drive assembly 7 includes a drive frame 71, which is fixedly connected to the processing tank 21. A third transmission shaft 72 and a drive disc 73 are rotatably connected to the two sides of the drive frame 71 near the top, respectively. A drive shaft is fixedly connected to the side of the drive shaft 72 near the drive frame 71, and the end of the drive shaft away from the third transmission shaft 72 passes through the drive frame 71 and is fixed to the drive disc 73. A second transmission belt 74 is sleeved between the third transmission shafts 72 on the two sets of drive frames 71, and the two sets of third transmission shafts 72 are connected by the second transmission belt 74. A second drive motor 75 is also fixedly connected to one set of drive frames 71, and the output end of the second drive motor 75 is fixed to the adjacent third transmission shaft 72 through a coupling. A drive rod 76 is also fixedly connected to the side of the drive disc 73 away from the drive frame 71. A drive frame 77 is sleeved on the drive rod 76, and the bottom of the drive frame 77 is fixed to the adjacent connecting plate 63.
[0053] Specifically, after the plastic particles in the conveyor box 47 fall into the rinsing frame 62, the second drive motor 75 is started. The second drive motor 75 drives one of the third drive shafts 72 to rotate. The two third drive shafts 72 rotate simultaneously through the transmission of the second drive belt 74, causing the two sets of drive discs 73 to rotate simultaneously. When the two sets of drive discs 73 rotate, the drive rods 76 on the two sets of drive discs 73 simultaneously push the two sets of drive frames 77 to move up and down. The two sets of drive frames 77 pull the rinsing frame 62 to move up and down continuously in the rinsing tank 61 through the two sets of connecting plates 63. The up and down movement of the rinsing frame 62 causes water in the rinsing tank 61 to continuously enter the rinsing frame 62, rinsing out the detergent on the surface of the plastic particles in the rinsing frame 62.
[0054] After the rinsing process is completed, the second drive motor 75 is controlled to rotate the drive rod 76 on the drive disc 73 to the highest position and then closes, so that the drive frame 77 is in the highest position on the drive disc 73, thereby causing the rinsing frame 62 to extend out of the rinsing tank 61 and be fixed. The cabinet door on the processing tank 21 can be opened to remove the cleaned plastic particles from the rinsing frame 62. For easy removal, the side wall of one side of the rinsing frame 62 can be made detachable, such as by plugging or hinge. The specific method can be selected as needed and can be easily achieved with existing technology, so it will not be described in detail here.
[0055] When the plastic particles in the rinsing frame 62 are removed, the water rinsed in the rinsing tank 61 can be drained through the drain pipe 64, and new clean water can be added to facilitate a new round of rinsing. After the plastic particles in the rinsing frame 62 are removed, the closing plate on the conveyor box 47 is opened so that the plastic particles in the conveyor box 47 can fall into the rinsing frame 62 to continue the rinsing process.
[0056] To better understand this invention, the specific implementation process is given below:
[0057] In use, a batch of plastic granules to be cleaned is first added to the storage box 31. The plastic granules slide down from the storage box 31 toward the feeding box 32. When cleaning is performed, the first drive motor 34 is started first, which drives the intermittent feeding cylinder 33 to rotate. When the opening on the intermittent feeding cylinder 33 rotates to the top, the plastic granules in the feeding box 32 fall into the opening of the intermittent feeding cylinder 33 and fall onto the scrubbing component 4 in the processing box 21 as the intermittent feeding cylinder 33 rotates. Through the intermittent feeding of the intermittent feeding cylinder 33, the plastic granules in the storage box 31 can be added to the processing box 21 in small amounts and multiple times to ensure the cleaning effect of the plastic granules.
[0058] When the first drive motor 34 drives the intermittent feeding cylinder 33 to rotate, the first transmission shaft 35 at the other end of the intermittent feeding cylinder 33 rotates simultaneously. The first transmission shaft 35 drives the second transmission shaft 54 to rotate through the first transmission belt 36. The second transmission shaft 54 drives the second bevel gear 53 to rotate through the transmission rod, so that the first bevel gear 52 rotates synchronously and drives the transmission disk 51 to rotate. The push rod 56 on the transmission disk 51 simultaneously pushes the transmission frame 57 to move back and forth. When the transmission frame 57 moves, the two sets of connecting rods 58 on the transmission frame 57 simultaneously pull the connecting block 59 to move. The connecting block 59 drives the connecting frame 42 to move. Through the cooperation of the fixed scrubbing board 41, the connecting frame 42 and the scrubbing sponge 43, the plastic particles between the fixed scrubbing board 41 and the scrubbing sponge 43 are scrubbed.
[0059] When the connecting block 59 pulls the connecting frame 42 toward the direction of the transmission component 5, multiple sets of sliding shafts 44 on both sides of the connecting frame 42 slide simultaneously in the guide groove 29. Under the guidance of the guide groove 29, the connecting frame 42 moves obliquely upward, causing the scrubbing sponge 43 to move slightly upward and no longer contact the plastic particles. At this time, the intermittent feeding cylinder 33 pours new plastic particles onto the fixed scrubbing plate 41. The plastic particles slide into the space between the fixed scrubbing plate 41 and the scrubbing sponge 43 along the gap between the scrubbing sponge 43 and the fixed scrubbing plate 41.
[0060] When the transmission disc 51 pushes the transmission frame 57 to move toward the processing box 21, the connecting block 59, driven by the connecting rod 58, pushes the connecting frame 42 to move down and reset, so that the scrubbing sponge 43 scrubs the plastic particles on the fixed scrubbing board 41. At the same time, it moves downward at an angle to further convey the plastic particles downward until the scrubbed plastic particles are introduced into the conveying box 47.
[0061] When the plastic granules in the conveyor box 47 fall into the rinsing frame 62, the second drive motor 75 is started. The second drive motor 75 drives one of the third drive shafts 72 to rotate. The two third drive shafts 72 rotate simultaneously through the transmission of the second drive belt 74, causing the two sets of drive discs 73 to rotate simultaneously. When the two sets of drive discs 73 rotate, the drive rods 76 on the two sets of drive discs 73 simultaneously push the two sets of drive frames 77 to move up and down. The two sets of drive frames 77 pull the rinsing frame 62 to move up and down continuously in the rinsing tank 61 through the two sets of connecting plates 63. The up and down movement of the rinsing frame 62 causes water in the rinsing tank 61 to continuously enter the rinsing frame 62, rinsing out the detergent on the surface of the plastic granules in the rinsing frame 62.
[0062] After the rinsing process is completed, the second drive motor 75 is controlled to rotate the drive rod 76 on the drive disc 73 to its highest position and then closes, so that the drive frame 77 is in the highest position on the drive disc 73. This causes the rinsing frame 62 to extend out of the rinsing tank 61 and be fixed in place. The cabinet door on the processing tank 21 is opened to remove the cleaned plastic particles from the rinsing frame 62. At the same time, the water used for rinsing in the rinsing tank 61 can be drained through the drain pipe 64, and new clean water can be added to facilitate a new round of rinsing. After the plastic particles in the rinsing frame 62 are removed, the closing plate on the conveyor box 47 is opened so that the plastic particles in the conveyor box 47 can fall into the rinsing frame 62 to continue the rinsing process.
[0063] It should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should also be within the scope of protection of this invention.
