Description

Technical Field

[0001] The invention relates to the technical field of plastic cleaning, and in particular to a circulating recycled plastic raw material cleaning device. Background Art

[0002] Plastic recycling refers to the process of remaking waste plastics into plastic raw materials or products through a series of processing. In the process of preparing plastics, the plastic raw materials need to be cleaned. The main purpose of cleaning plastic raw materials is to remove dirt, oil, dust and other impurities attached to the surface of the plastic to improve the purity and processing performance of the plastic. At the same time, cleaning can also help remove odors in plastics, making them more suitable for the manufacture of products in sensitive fields such as food packaging and medical devices.

[0003] The existing Chinese patent with publication number CN116000003B discloses a raw material cleaning device for plastic product production, but the above patent and the prior art also have the following defects: First, the above patent uses an arc roller to stir water to prevent the plastic raw materials from floating up. However, in actual operation, the plastic raw materials are mostly granular. When the water level in the cleaning chamber is higher than the arc roller, the plastic raw materials will float above the arc roller. Then, the rotation of the arc roller alone cannot drive the floating plastic raw materials to surge downward. Secondly, in the process of cleaning the plastic raw material, the plastic raw material is cleaned by contacting with the first cleaning brush and the second cleaning brush. During this process, since the arc roller rotates continuously, the contact time between the plastic raw material and the second cleaning brush is very short, which eventually leads to incomplete cleaning. Third, in the process of cleaning the plastic raw materials, the dirt washed from the plastic raw materials will fall directly into the water, and the above patent does not mention how to clean the dirt in the water. If the dirt is not cleaned in time, the dirt in the water will adhere to the plastic particles again.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] refer to Figures 1 to 20 The recycling type recycled plastic raw material cleaning device shown in the figure comprises a cleaning box 1, the top of the cleaning box 1 is an open structure, a rotating cleaning mechanism is arranged in the cleaning box 1, and the rotating cleaning mechanism comprises a plurality of groups of brush rollers 2 (such as Figure 7As shown in FIG. 1 , each set of brush rollers 2 is rotatably connected to the cleaning box 1, and each set of brush rollers 2 is provided with a one-way rotation mechanism 3 and an energy storage drive mechanism 4 at both ends. The one-way rotation mechanism 3 includes a ratchet mechanism and a rotating shaft 5. The rotating shaft 5 is rotatably arranged outside the cleaning box 1 (as shown in FIG. 1 ). Fig. 9 As shown in FIG. 1 ), the ratchet mechanism connects the rotating shaft 5 to one end of the brush roller 2, and the energy storage drive mechanism 4 includes a housing 6 and a spring 7, and the housing 6 is fixedly connected to the outer wall of the cleaning box 1 (as shown in FIG. 1 ). Fig.10 As shown in the figure, the spring 7 is arranged in the housing 6, the other end of the brush roller 2 is connected to the spring 7, a horizontal lifting and pressing plate 8 is arranged above the cleaning box 1, a plurality of leakage holes 9 are opened on the lifting and pressing plate 8, each rotating shaft 5 is connected to a gear 10, and a plurality of racks 11 corresponding to the gears 10 are arranged on the lifting and pressing plate 8, and each rack 11 is vertical (as shown in the figure). Fig.14 As shown), each rack 11 is meshed with the gear 10, and a drain outlet 12 and a water spray mechanism are provided on both sides of the cleaning box 1, and a lifting sealing plate 13 (as shown) is provided on the drain outlet 12 Fig.12 As shown in the figure, a dirt filtering mechanism is provided outside the cleaning box 1 near the sewage outlet 12.

[0021] In the initial state, the lifting sealing plate 13 blocks the sewage outlet 12, and then an appropriate amount of water is injected into the cleaning box 1, and then the plastic particles to be cleaned are poured into the cleaning box 1. When the plastic particles are poured into the cleaning box 1, the plastic particles will float on the water surface. Thereafter, the plastic particles floating on the water surface are pressed toward the plurality of groups of brush rollers 2 by the lifting and pressing plates 8. In this process, the water in the cleaning box 1 passes through the leakage holes 9 and covers the lifting and pressing plates 8, and the plastic particles are pressed toward the plurality of groups of brush rollers 2 by the lifting and pressing plates 8. At the same time, the plurality of racks 11 will descend together with the lifting and pressing plates 8, and each rack 11 in the descent will The gear 10 will be driven to rotate by the corresponding gear 10. When the gear 10 rotates, the gear 10 will drive the rotating shaft 5 to rotate. The rotating shaft 5 will drive the brush roller 2 to rotate through the ratchet mechanism. At this time, the rotating brush roller 2 will drive the spring 7 to wind up. After the spring 7 is wound up, it will generate an elastic force to drive the brush roller 2 to rotate in the opposite direction. When the plastic particles are close to the brush roller 2, the rack 11 passes over the gear 10 downward, and the gear 10 is no longer meshed with the rack 11. The spring 7 will release the elastic force to drive the corresponding brush roller 2 to rotate in the opposite direction. At this time, the plastic particles under the lifting and pressing plate 8 are brushed by the rotating brush roller 2. During the brushing process, the lifting and pressing plate 8 is lifted. The pressure reducing plate 8 is in a suspended state, and the dirt brushed off from the plastic particles will float upward on the water surface. At this time, the lifting sealing plate 13 is opened, and the water spraying mechanism sprays water toward the cleaning box 1, and the dirt floating on the water surface is washed toward the sewage outlet 12 through the water flow, and finally the dirt will be discharged to the dirt filtering mechanism through the sewage outlet 12 with the water flow, and the dirt filtering mechanism will filter the dirt in the water. When the elastic force stored in the clockwork 7 is completely released, the brush roller 2 no longer rotates, and thereafter the lifting pressure plate 8 rises. In this process, the rack 11 is meshed with the gear 10 again, but at this time, through the unique unidirectional rotation action of the ratchet mechanism, the brush roller 2 will not rotate. During the ascending process of the lifting and pressing plate 8, the lifting and closing plate 13 will close the sewage outlet 12 to prevent the plastic particles floating with the lifting and pressing plate 8 from being discharged from the sewage outlet 12. After the lifting and pressing plate 8 ascends, the lifting and pressing plate 8 will descend again, and the cycle will be repeated. Finally, the plastic particles will be fully cleaned in the cleaning box 1. When the plastic particles are cleaned, the water circulation in the cleaning box 1 is realized through the water spraying mechanism and the sewage outlet 12 to ensure that the sewage can be discharged in time without causing secondary pollution to the plastic particles. When the plastic particles are cleaned, the plastic particles in the cleaning box 1 can be fished out.

[0022] In order to show how the brush roller 2 is rotatably connected to the cleaning box 1, the following features are provided: Each brush roller 2 includes a brush barrel 14 and a rotating roller 15. The outer wall of the rotating roller 15 is formed with a plurality of inserts 16 (such as Fig.17As shown in FIG. 1 , the length direction of each insert 16 is parallel to the axial direction of the roller 15. A cylindrical through groove 17 is provided in the brush cylinder 14 for the roller 15 to pass through. A plurality of slots 18 are provided on the cylindrical through groove 17 to match the insert 16. A plurality of through holes 19 are provided on both sides of the cleaning box 1 (as shown in FIG. Fig. 9 As shown), the two ends of each roller 15 pass through two corresponding through holes 19 respectively, and a plurality of No. 1 shaft seats 20 corresponding to the through holes 19 are fixedly provided on the outer wall of one side of the cleaning box 1, and one end of each roller 15 is connected to the No. 1 shaft seat 20, and sealing rings 21 and sealing sleeves 22 are respectively provided in the through holes 19 on both sides of the cleaning box 1.

[0023] When installing the brush roller 2 into the cleaning box 1, first place the brush cylinder 14 horizontally in the cleaning box 1, and then pass the roller 15 through the cleaning box 1 and the brush cylinder 14 in turn through the through hole 19. When the roller 15 passes through the brush cylinder 14, ensure that each insertion strip 16 is inserted into the corresponding slot 18. After the roller 15 is inserted into the brush cylinder 14, one end of the roller 15 is connected to the corresponding No. 1 shaft seat 20. The sealing sleeve 22 is used to cooperate with the No. 1 shaft seat 20 to lubricate the rotation of the roller 15. The sealing sleeve 22 can also prevent water in the cleaning box 1 from leaking out from the corresponding through hole 19. The sealing ring 21 plays a dynamic seal to prevent water from leaking out from the corresponding through hole 19.

[0024] In order to show the specific structure of the ratchet mechanism, the following features are set: Each ratchet mechanism includes a ratchet plate 23 and a plurality of sets of elastic pawls 24 (such as Fig.16 As shown in the figure, the ratchet plate 23 is coaxially fixedly connected to the end of the corresponding roller 15, a circle of ratchet teeth 25 is formed at the outer edge of the ratchet plate 23, and a second shaft seat 26 fixedly connected to the cleaning box 1 is provided on the side of the ratchet plate 23. The rotating shaft 5 is connected to the second shaft seat 26, and the rotating shaft 5 is coaxial with the corresponding roller 15. Several groups of elastic pawls 24 are evenly distributed along the circumferential direction of the rotating shaft 5, each group of elastic pawls 24 are connected to the rotating shaft 5, and each group of elastic pawls 24 are meshed with the ratchet teeth 25.

[0025] When the lifting and pressing plate 8 descends, the rack 11 drives the gear 10 to rotate. When the gear 10 rotates, the gear 10 drives the rotating shaft 5 to rotate. At this time, several groups of elastic pawls 24 will drive the roller 15 to rotate through the ratchet disk 23. The roller 15 stores energy for the spring 7 by rotating. When the lifting and pressing plate 8 descends until the rack 11 passes over the gear 10, the rack 11 no longer meshes with the gear 10. At this time, the spring 7 will release the stored elastic force to drive the roller 15 to rotate in the opposite direction. Finally, the roller 15 will drive the brush roller 2 to brush the plastic particles under the lifting and pressing plate 8. When the lifting and pressing plate 8 rises, the rack 11 drives the gear 10 to rotate in the opposite direction. At this time, each group of elastic pawls 24 will slide on the ratchet 25, and several groups of elastic pawls 24 will not drive the ratchet disk 23 to rotate, finally ensuring that when the lifting and pressing plate 8 rises, the roller 15 will not rotate, preventing the roller 15 from twisting the spring 7 in the opposite direction.

[0026] In order to show how the spring 7 is connected to the brush roller 2, the following features are provided: Each housing 6 is circular (such as Fig.18 As shown in the figure, the side of each shell 6 facing away from the cleaning box 1 is an open structure, and a circular cover plate 27 is fixedly provided on the open side of each shell 6. A circle of retaining ring 28 is formed at the outer edge of the circular cover plate 27. The spring 7 is arranged in the retaining ring 28, and the outer edge end of the spring 7 is fixedly connected to the circular cover plate 27. A circular hole 29 is opened on the side of each shell 6 facing the cleaning box 1, and a connecting pin 30 is formed on the end of each roller 15 close to the shell 6 and passes through the shell 6 and is fixedly connected to the center end of the spring 7.

[0027] When the roller 15 rotates, the roller 15 will reel in the mainspring 7 via the connecting pin 30. After being reeled in, the mainspring 7 will store energy to generate elastic force. When the rack 11 is no longer meshed with the gear 10, the mainspring 7 releases the elastic force. At this time, the retaining ring 28 is used to limit the deformation of the mainspring 7 when releasing the elastic force, ensuring that the mainspring 7 will not be too loose after the elastic force is completely released.

[0028] In order to show how the lifting plate 8 is lifted and lowered, the following features are set: Both ends of the lifting and pressing plate 8 are formed with vertical frames 31, and a horizontal connecting rod 32 is fixed between the two vertical frames 31. A vertical cylinder 33 is provided above the connecting rod 32, and the output end of the cylinder 33 is fixedly connected to the connecting rod 32 downward.

[0029] In actual use, the cylinder 33 can be mounted above the cleaning box 1 through a gantry (not shown in the figure). When the cylinder 33 is started, the cylinder 33 will drive the connecting rod 32 to rise and fall, and the connecting rod 32 will drive the entire lifting plate 8 to rise and fall through the two vertical frames 31.

[0030] In order to show how the rack 11 is connected to the lifting plate 8, the following features are set: The top of the lifting and pressing plate 8 is formed with a plurality of L-shaped rods 34 (such as Fig.14 As shown in the figure, the vertical end of each L-shaped rod 34 is fixedly connected to the lifting and pressing plate 8 downward, and the horizontal end of each L-shaped rod 34 is laterally extended outward from the lifting and pressing plate 8. A lifting rod 35 is fixedly connected to the horizontal end of each L-shaped rod 34 vertically downward, and each rack 11 is formed at the lower end of the lifting rod 35.

[0031] When the lifting and pressing plate 8 descends, the lifting and pressing plate 8 will drive the lifting rod 35 to descend through the L-shaped rod 34. When the lifting rod 35 descends, the lifting rod 35 will drive the rack 11 to move toward the gear 10. When the rack 11 is meshed with the gear 10, as the rack 11 descends, the gear 10 will be driven to rotate. At this time, the roller 15 will reel the spring 7 to store energy for the spring 7. When the lifting rod 35 descends until the rack 11 passes over the gear 10, the gear 10 is no longer meshed with the rack 11. At this time, the gear 10 is in a free state, and the spring 7 will immediately release the elastic force to drive the roller 15 to rotate in the opposite direction. At this time, the brush cylinder 14 scrubs the plastic particles under the lifting and pressing plate 8 by rotating.

[0032] In order to show how the lifting cover plate 13 is lifted and lowered, the following features are provided: A plurality of cylindrical shells 36 (such as Fig.13 As shown in the figure, each cylindrical shell 36 is vertical, and each cylindrical shell 36 is located below the sewage outlet 12. The top of each cylindrical shell 36 is an open structure. A sliding rod 37 and a spring 38 are provided in each cylindrical shell 36. The sliding rod 37 is vertical, and an expansion block 39 is formed at the bottom end of the sliding rod 37. The expansion block 39 is cylindrical. The spring 38 is arranged below the sliding rod 37. The two ends of the spring 38 respectively conflict with the expansion block 39 and the inner bottom wall of the cylindrical shell 36. A sealing cover 40 is fixed on the open end of each cylindrical shell 36. The upper end of the sliding rod 37 passes through the sealing cover 40. The lifting sealing plate 13 is in contact with the inner wall of the cleaning box 1. The top of the lifting sealing plate 13 is formed with a transverse support bar 41, and the top of each sliding rod 37 is fixedly connected to the transverse support bar 41.

[0033] In the initial state, the spring 38 releases its elastic force to drive the slide bar 37 to rise. At this time, the slide bar 37 will drive the entire lifting and closing plate 13 to rise and block the sewage outlet 12 by contacting the transverse support bar 41. When the lifting and closing plate 8 is lowered, one end of the lifting and closing plate 8 will contact the transverse support bar 41 downward. Thereafter, the lifting and closing plate 13 will fall with the lowering of the lifting and closing plate 8. When the lifting and closing plate 13 is lowered, the sewage outlet 12 gradually opens, and each slide bar 37 will compress the spring 38 downward, so that the spring 38 produces Elastic force, when the plastic particles are brushed, the dirt washed from the plastic particles will float up and eventually be discharged through the drain outlet 12. When the lifting and pressing plate 8 rises, the elastic force of the spring 38 drives the slide bar 37 to rise. At this time, the lifting and closing plate 13 will rise together with the lifting and pressing plate 8. Finally, the lifting and closing plate 13 will block the drain outlet 12 again to prevent the plastic particles floating with the lifting and pressing plate 8 from being discharged from the drain outlet 12. When the plastic particles are cleaned, the plastic particles in the cleaning box 1 can be fished out.

[0034] In order to show the specific structure of the water spray mechanism, the following features are set: The water spraying mechanism includes a plurality of nozzles 42 (such as Figure 7 As shown in the figure), each nozzle 42 is fixed on the inner wall of one side of the cleaning box 1, and each nozzle 42 faces the sewage outlet 12.

[0035] In actual use, several nozzles 42 are connected to an external water pipe (not shown in the figure). When the lifting and pressing plate 8 presses the plastic particles down to close to several groups of brush rollers 2, the lifting and pressing plate 8 stops descending. At this time, the external water pipe passes clean water into each nozzle 42, and the nozzle 42 sprays the clean water into the cleaning chamber, so that the dirt floating on the water surface is flushed to the sewage outlet 12 by the clean water sprayed into the cleaning chamber.

[0036] In order to show the specific structure of the dirt filtering mechanism, the following features are set: The scale filtering mechanism includes a water collecting box 43, a roll filter and a motor 44. The water collecting box 43 is horizontally fixed on the outer wall of the cleaning box 1, and the water collecting box 43 is located below the sewage outlet 12. A drain outlet 45 is provided at one end of the water collecting box 43. The roll filter includes a central axis 46 and a filter cloth 47 (such as Fig.11 As shown in the figure, a No. 1 support frame 48 and a No. 2 support frame 49 are respectively provided at both ends of the water collecting box 43, the central axis 46 rotates horizontally on the No. 1 support frame 48, the motor 44 is horizontally fixed on the No. 2 support frame 49, and a winding rod 50 is coaxially fixed to the output end of the motor 44. The filter cloth 47 is wound around the central axis 46, and one end of the filter cloth 47 horizontally passes over the top of the water collecting box 43 and is then wound around the winding rod 50. A guide plate 51 located below the sewage outlet 12 is formed on the outer wall of the cleaning box 1.

[0037] The dirt in the cleaning box 1 is discharged from the drain port 12 along with the water. After the dirt and water are discharged, the dirt and water will fall downward onto the horizontal filter cloth 47 through the guide plate 51. The dirt will be blocked by the filter cloth 47, and the water will pass through the filter cloth 47 and fall into the water collecting box 43. After the water falls into the water collecting box 43, the water will be discharged through the drain port 45. In actual use, the drain port 45 is connected to the cleaning box 1 through a return pipe (not shown in the figure), so as to realize water circulation. When the filter cloth 47 blocks the dirt, the motor 44 will drive the winding roller 50 to rotate. Thereafter, the filter cloth 47 wound on the central shaft 46 will be gradually pulled toward the sewage outlet 12, and the filter cloth 47 full of dirt will be wound around the winding roller 50. When all the dirt in the cleaning box 1 has been filtered out, the filter cloth 47 above the water collecting box 43 will be cut off, and then the filter cloth 47 on the winding roller 50 will be removed, and finally the filter cloth 47 on the central shaft 46 will be wound around the winding roller 50.

[0038] In order to promote the rise of dirt in the washing box 1, the following features are provided: An aeration mechanism is fixedly arranged at the bottom of the cleaning box 1, and the aeration mechanism includes an aeration pipe 52 and a plurality of aeration nozzles 53 (such as Figure 8 As shown in FIG. 1 ), a plurality of aeration nozzles 53 are fixedly connected to the bottom wall of the cleaning tank 1 , and an aeration pipe 52 connects the plurality of aeration nozzles 53 .

[0039] In actual use, the aeration pipe 52 is connected to an external air source (not shown in the figure). When the plastic particles are scrubbed, the external air source will pass the gas into each group of aeration nozzles 53 through the aeration pipe 52. Thereafter, each group of aeration nozzles 53 will spray gas into the cleaning box 1, and the rising gas will promote the floating of dirt in the cleaning box 1. Each group of aeration nozzles 53 is equipped with a one-way valve (not shown in the figure) to prevent the water in the cleaning box 1 from flowing back into the aeration pipe 52.

[0040] Working principle: In the initial state, the lifting sealing plate 13 blocks the sewage outlet 12, and then an appropriate amount of water is injected into the cleaning box 1, and then the plastic particles to be cleaned are poured into the cleaning box 1. When the plastic particles are poured into the cleaning box 1, the plastic particles will float on the water surface. Thereafter, the plastic particles floating on the water surface are pressed toward the plurality of groups of brush rollers 2 by the lifting and pressing plates 8. In this process, the water in the cleaning box 1 passes through the leakage holes 9 and covers the lifting and pressing plates 8, and the plastic particles are pressed toward the plurality of groups of brush rollers 2 by the lifting and pressing plates 8. At the same time, the plurality of racks 11 will descend together with the lifting and pressing plates 8, and each rack 11 in the descent will The gear 10 will be driven to rotate by the corresponding gear 10. When the gear 10 rotates, the gear 10 will drive the rotating shaft 5 to rotate. The rotating shaft 5 will drive the brush roller 2 to rotate through the ratchet mechanism. At this time, the rotating brush roller 2 will drive the spring 7 to wind up. After the spring 7 is wound up, it will generate an elastic force to drive the brush roller 2 to rotate in the opposite direction. When the plastic particles are close to the brush roller 2, the rack 11 passes over the gear 10 downward, and the gear 10 is no longer meshed with the rack 11. The spring 7 will release the elastic force to drive the corresponding brush roller 2 to rotate in the opposite direction. At this time, the plastic particles under the lifting and pressing plate 8 are brushed by the rotating brush roller 2. During the brushing process, the lifting and pressing plate 8 is lifted. The pressure reducing plate 8 is in a suspended state, and the dirt brushed off from the plastic particles will float upward on the water surface. At this time, the lifting sealing plate 13 is opened, and the water spraying mechanism sprays water toward the cleaning box 1, and the dirt floating on the water surface is washed toward the sewage outlet 12 through the water flow, and finally the dirt will be discharged to the dirt filtering mechanism through the sewage outlet 12 with the water flow, and the dirt filtering mechanism will filter the dirt in the water. When the elastic force stored in the clockwork 7 is completely released, the brush roller 2 no longer rotates, and thereafter the lifting pressure plate 8 rises. In this process, the rack 11 is meshed with the gear 10 again, but at this time, through the unique unidirectional rotation action of the ratchet mechanism, the brush roller 2 will not rotate. During the ascending process of the lifting and pressing plate 8, the lifting and closing plate 13 will close the sewage outlet 12 to prevent the plastic particles floating with the lifting and pressing plate 8 from being discharged from the sewage outlet 12. After the lifting and pressing plate 8 ascends, the lifting and pressing plate 8 will descend again, and the cycle will be repeated. Finally, the plastic particles will be fully cleaned in the cleaning box 1. When the plastic particles are cleaned, the water circulation in the cleaning box 1 is realized through the water spraying mechanism and the sewage outlet 12 to ensure that the sewage can be discharged in time without causing secondary pollution to the plastic particles. When the plastic particles are cleaned, the plastic particles in the cleaning box 1 can be fished out.
