Description

Technical Field

[0001] This invention relates to the field of plastic recycling equipment technology, and more specifically to a highly efficient decomposition and recycling device for waste plastics. Background Technology

[0002] With the increasing emphasis on resource recycling, the plastic bottle recycling industry has ushered in unprecedented development opportunities. As a common plastic product, the recycling and reuse of plastic bottles is of great significance for saving resources and reducing environmental pollution. In the process of plastic bottle recycling, crushing equipment is a key piece of equipment, and its performance directly affects the recycling efficiency and quality.

[0003] The shortcomings of existing technologies: When recycling plastics, due to the wide distribution of waste plastic sources, some dust and stains inevitably adhere to the waste plastics. Usually, it is necessary to clean the waste plastics to remove the dust and stains attached to the surface. However, after cleaning, a large amount of moisture remains on the waste plastics. In order not to affect the subsequent recycling of plastics, a lot of time is required to remove the moisture from the waste plastics, which greatly affects the recycling efficiency of waste plastics. To address this, we propose a high-efficiency decomposition and recycling device for waste plastics. Summary of the Invention

Each of the partitions is equidistantly installed between the rotating disks and slidably connected to the inner and outer cylinders. A pair of drive gear rings are rotatably connected to both sides of the outer cylinder. Multiple guide frames are installed inside the drive gear rings. The guide seat is installed on the circumferential surface of the rotating disk and slidably connected to the guide frame. A first spring is installed between the guide seat and the guide frame. Slide seats are installed at both ends of the outer cylinder. A resistance block is installed at the lower end of the slide rod slidably connected inside the slide seat. The resistance block is slidably connected to the resistance gear ring installed on the circumferential surface of the rotating disk. A second spring is installed between the resistance block and the slide seat.

[0006] Preferably, a dual-axis motor is mounted on the upper end of the base, and a drive shaft is mounted on the output end of each dual-axis motor. A driven shaft is mounted between the fixed frames, and a drive gear mounted on the circumferential surface of the driven shaft meshes with a drive gear ring. The drive shaft and the driven shaft are connected by a sprocket assembly.

[0007] Preferably, the crushing assembly includes a crushing box, a drive rod, and a crushing roller. The crushing box is installed on the upper end of the outer cylinder. A pair of drive rods are rotatably connected inside the crushing box. The crushing rollers are installed on the circumferential surface of the drive rods. Intermeshing linkage gears are installed on the circumferential surface of the drive rods. One of the drive rods is connected to the output end of a crushing motor installed on the surface of the crushing box.

[0008] Preferably, the flushing assembly includes a mounting groove, a diversion pipe, a high-pressure nozzle, and an arc-shaped connecting pipe. The mounting grooves are all formed inside the inner cylinder, the diversion pipes are all installed in the mounting grooves, the high-pressure nozzles are all installed on the diversion pipes, and the arc-shaped connecting pipes are all connected to the input end of the diversion pipes. The input pipe installed on the arc-shaped connecting pipe is used to connect to an external water pump.

[0009] Preferably, agitator plates are installed at equal intervals between the rotating disks, the agitator plates are slidably connected to the inner wall of the outer cylinder, and multiple drainage holes are provided on the circumferential surface of the outer cylinder.

[0010] Preferably, the dewatering assembly includes a conveying trough, a connecting trough, a connecting port, and a squeezing trough. The conveying trough, squeezing trough, and connecting port are all located inside the inner cylinder. The connecting trough is located on the circumferential surface of the inner cylinder. A pair of auger blades with opposite directions are mounted on the circumferential surface of a rotating shaft rotatably connected inside the inner cylinder. The rotating shaft is connected to the output end of a drive motor mounted on the surface of the inner cylinder. A bidirectional electric push rod is installed inside the squeezing trough. A squeezing cylinder is installed at the output end of each bidirectional electric push rod. Squeezing blocks are connected to both ends of the inner cylinder via damping rods. A strong tension spring is installed between each squeezing block and the inner cylinder. Multiple holes are formed on the surface of the squeezing block.

[0011] Preferably, a support rod is installed at the upper end of the base, and a slanted hole plate is installed at the upper end of the support rod.

[0012] Preferably, a baffle plate is installed at the upper end of the machine base, and a drain pipe is installed at the lower end of the machine base.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention controls the rotation of a rotating disk, which in turn causes the partition and agitator to vibrate during the rotation. When the crushed waste plastic falls into the outer cylinder, the rotating partition pushes the waste plastic to move, and the vibration generated by the partition causes the crushed waste plastic to vibrate. During the movement, the washing component impacts the vibrating waste plastic, causing its surface to be evenly washed and the mixed dust to be washed away, thereby achieving the effect of cleaning the waste plastic.

[0015] 2. This invention controls the operation of a drive motor to activate a bidirectional electric push rod, which in turn moves the extrusion cylinder mounted on the output end to both sides. This pushes the waste plastic in the extrusion groove to both sides. Through the cooperation of the extrusion cylinder and the extrusion block, the water in the waste plastic can be squeezed out through the holes, removing most of the water from the waste plastic. As the output end of the bidirectional electric push rod continuously controls the extrusion cylinder to move to both sides, the strong tension spring and the resistance rod are stretched, and the extrusion block moves to both sides. When the bidirectional electric push rod retracts and resets, the extrusion block slowly resets through the action of the damping rod, and the extruded waste plastic is released from the extrusion state. Finally, the extruded waste plastic falls downwards onto the inclined plate, where it can be collected and quickly dried by a vibratory dryer, reducing the time required for waste plastic recycling.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The waste plastic high-efficiency decomposition and recycling device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1-11 As shown, in one embodiment, a high-efficiency waste plastic decomposition and recycling device is proposed, including a base 1. A fixed frame 101 is installed on the upper end of the base 1. An outer cylinder 102 and an inner cylinder 103 are installed on the upper end of the fixed frame 101. The inner cylinder 103 is located inside the outer cylinder 102. A crushing component 2 is installed on the upper end of the outer cylinder 102. A rinsing component 3 and a water removal component 4 are arranged inside the inner cylinder 103. An agitation component 5 is arranged inside the outer cylinder 102. The agitation component 5 includes a rotating disk 501, a partition 502, a drive gear ring 503, a guide frame 504, and a guide seat 505. A pair of rotating disks 501 are installed between the inner cylinder 103 and the outer cylinder 102. The rotating disks 501 are slidably connected to the inner cylinder 103 and the outer cylinder 102. Multiple partitions... Plates 502 are equidistantly installed between rotating disks 501 and are slidably connected to the inner cylinder 103 and the outer cylinder 102. A pair of drive gear rings 503 are rotatably connected to both sides of the outer cylinder 102. Multiple guide frames 504 are installed inside the drive gear rings 503. Guide seats 505 are installed on the circumferential surface of rotating disks 501 and are slidably connected to the guide frames 504. A first spring 506 is installed between the guide seat 505 and the guide frame 504. Slide seats 507 are installed at both ends of the outer cylinder 102. A resistance block 508 is installed at the lower end of the slide rod slidably connected inside the slide seat 507. The resistance block 508 is slidably connected to the resistance gear ring 509 installed on the circumferential surface of rotating disks 501. A second spring 5010 is installed between the resistance block 508 and the slide seat 507.

[0037] In practical application, waste plastic is fed into the crushing assembly 2 for crushing. After being crushed into small pieces, the waste plastic falls into the inner cylinder 103. At this time, by controlling the rotation of the drive gear ring 503, the drive gear ring 503 drives the guide frame 504 to rotate. The guide frame 504, through the cooperation of the first spring 506, drives the guide seat 505 and the rotating disk 501 to rotate. The rotating disk 501 drives the resistance gear ring 509 to rotate. When the teeth of the resistance gear ring 509 contact the resistance block 508, the drive gear ring 509 rotates. The moving gear ring 503 and guide frame 504 rotate, while the resistance gear ring 509 stops rotating due to the obstruction of the resistance block 508. At this time, the first spring 506 on one side will be compressed. When the compression force reaches a certain level, the resistance gear ring 509 will pass over the resistance block 508 and push the resistance block 508 upward. Then, the compressed first spring 506 will release its tension, causing the rotating disk 501 to vibrate. Subsequently, the second spring 5010 will push the resistance block 508 to descend and reset. As the teeth of the resistance gear ring 509... As the waste plastic continuously passes over the resistance block 508, the rotating disk 501 vibrates, resulting in continuous vibration during its rotation. This vibration, in turn, causes the partition 502 to vibrate. When the crushed waste plastic falls into the inner cylinder 103, the partition 502 pushes it to rotate and move within the outer cylinder 102. The vibration generated by the partition 502 during this movement further vibrates the crushed waste plastic. Simultaneously, the washing component 3 impacts the vibrating waste plastic, ensuring its surface is evenly washed and removing any mixed dust. The dust is then discharged from the outer cylinder 102 along with the water flow, separating from the crushed waste plastic. As the waste plastic rotates, it moves to the dewatering component 4, where it is compressed into blocks, removing a significant amount of moisture. This greatly improves the efficiency of drying the waste plastic and reduces the time required for waste plastic recycling.

[0038] like Figure 5 and 7 As shown, in one embodiment, a dual-axis motor 6 is mounted on the upper end of the base 1. A drive shaft 601 is mounted on the output end of each dual-axis motor 6. A driven shaft 602 is mounted between the fixed frames 101. A drive gear 603 mounted on the circumferential surface of the driven shaft 602 meshes with a drive gear ring 503. The drive shaft 601 and the driven shaft 602 are connected by a sprocket set 604.

[0039] In practical application, the present invention controls the operation of the dual-axis motor 6, which in turn drives the shaft 601 to rotate. The drive shaft 601 drives the driven shaft 602 to rotate via the sprocket set 604. The driven shaft 602 drives the drive gear 603 to rotate, and the drive gear 603 drives the drive gear ring 503 to rotate, thereby achieving the effect of controlling the operation of the stirring component 5.

[0040] like Figure 2 , 3 As shown in Figure 5, in one embodiment, the crushing assembly 2 includes a crushing box 201, a drive rod 202, and a crushing roller 203. The crushing box 201 is installed on the upper end of the outer cylinder 102. A pair of drive rods 202 are rotatably connected inside the crushing box 201. The crushing rollers 203 are all installed on the circumferential surface of the drive rods 202. The circumferential surface of the drive rods 202 is equipped with meshing linkage gears 204. One of the drive rods 202 is connected to the output end of a crushing motor 205 installed on the surface of the crushing box 201.

[0041] In practical application, the present invention controls the operation of the crushing motor 205, which drives one of the drive rods 202 to rotate. The drive rod 202 rotates in opposite directions through the action of the linkage gear 204, thereby driving the two crushing rollers 203 to rotate in opposite directions. When waste plastic enters the crushing box 201, it can be crushed by the rotating crushing rollers 203 and then conveyed downward to the outer cylinder 102 for subsequent recycling.

[0042] like Figure 4 , 14 As shown in Figure 15, in one embodiment, the flushing assembly 3 includes a mounting groove 301, a diversion pipe 302, a high-pressure nozzle 303, and an arc-shaped connecting pipe 304. Multiple mounting grooves 301 are all opened inside the inner cylinder 103, multiple diversion pipes 302 are all installed in the mounting grooves 301, multiple high-pressure nozzles 303 are all installed on the diversion pipes 302, and the arc-shaped connecting pipes 304 are all connected to the input end of the diversion pipes 302. An input pipe 305 installed on the arc-shaped connecting pipe 304 is used to connect to an external water pump.

[0043] In practical application, the inlet pipe 305 is connected to an external water pump to draw water from the outside into the arc-shaped connecting pipe 304. Then, the water is sprayed through the high-pressure nozzle 303 installed on the diversion pipe 302, impacting the waste plastic fragments rotating in the outer cylinder 102. This achieves the effect of rinsing the crushed waste plastic, cleaning the dust attached to its surface, and discharging the dust along with the water from the outer cylinder 102.

[0044] like Figure 3 , 7As shown in Figures 9 and 10, in one embodiment, stirring plates 7 are installed at equal intervals between rotating disks 501. The stirring plates 7 are slidably connected to the inner wall of the outer cylinder 102, and multiple drainage holes 701 are provided on the circumferential surface of the outer cylinder 102.

[0045] In practical application, the rotating disc 501 can drive the agitator 7 to vibrate during its rotation and shaking. The agitator 7 and the partition 502 vibrate simultaneously during rotation, which can increase the activity frequency of the waste plastic in the outer cylinder 102. During the washing of the waste plastic, the water containing dust can be discharged from the outer cylinder 102 through the drain hole 701. Since there is no drain hole 701 at the rear of the outer cylinder 102, when the waste plastic just enters the outer cylinder 102 and is rotated and conveyed at the rear, the water sprayed by the high-pressure nozzle 303 can accumulate between the partitions 502. When the partitions 502 vibrate, they can agitate the water between the partitions 502, causing the waste plastic to be agitated along with the water, thereby improving the cleaning effect of dust on the waste plastic.

[0046] like Figure 12 , 13 As shown in Figures 14, 16, 17, and 18, in one embodiment, the dewatering assembly 4 includes a conveying groove 401, a connecting groove 404, a connecting port 403, and a squeezing groove 402. The conveying groove 401, squeezing groove 402, and connecting port 403 are all formed inside the inner cylinder 103. The connecting groove 404 is formed on the circumferential surface of the inner cylinder 103. A pair of auger blades 406 with opposite directions are mounted on the circumferential surface of a rotating shaft 405 rotatably connected inside the inner cylinder 103. The drive shaft 405 is connected to the output end of the drive motor 407 mounted on the surface of the inner cylinder 103. A bidirectional electric push rod 408 is installed in the extrusion groove 402. An extrusion cylinder 409 is installed at the output end of the bidirectional electric push rod 408. An extrusion block 4013 is connected to both ends of the inner cylinder 103 through a damping rod 4010. A strong tension spring 4011 is installed between the extrusion block 4013 and the inner cylinder 103. Multiple holes 4012 are opened on the surface of the extrusion block 4013.

[0047] In practical application, as the rotating disk 501 rotates, the partition 502 pushes the waste plastic to the connecting groove 404, transferring it to the conveying groove 401. At this time, the drive motor 407 is controlled to operate, rotating a pair of oppositely oriented auger blades 406. This causes the waste plastic in the conveying groove 401 to be conveyed to the connecting port 403. The waste plastic then passes through the connecting port 403 into the extrusion groove 402. Then, the bidirectional electric push rod 408 is controlled to operate, moving the extrusion cylinder 409 installed on the output end to both sides, pushing the waste plastic in the extrusion groove 402 to both sides. Both ends of the extrusion groove 402 are blocked by extrusion blocks 4013. Through the cooperation of the extrusion cylinder 409 and the extrusion blocks 4013, the water in the waste plastic can be squeezed out through the hole 4012, removing most of the water from the waste plastic. As the output end of the bidirectional electric push rod 408 continuously controls the extrusion cylinder 409 to move to both sides, the strong tension spring 4011 and the resistance rod will be stretched, and the extrusion block 4013 will move to both sides. Then, the bidirectional electric push rod 408 is controlled to retract and reset. Through the action of the damping rod 4010, the extrusion block 4013 slowly resets, and the extruded waste plastic can be released from the extrusion state. Finally, the extruded waste plastic falls downward.

[0048] In one embodiment of the present invention, the strong tension spring 4011 provides a strong pulling force to the extrusion block 4013. In conjunction with the extrusion cylinder 409, this force is sufficient to extrude the pulverized waste plastic into blocks before the extrusion block 4013 is removed from the inner cylinder 103. Simultaneously, when the extrusion cylinder 409 is extruding, it can block the connection port 403. The speed can be increased when the extrusion cylinder 409 resets. After resetting, the cleaned waste plastic is replenished into the extrusion groove 402 through the connection port 403, achieving continuous and automatic recycling of waste plastic and improving the recycling efficiency.

[0049] like Figure 1 and 2 As shown, in one embodiment, a support rod 8 is installed on the upper end of the base 1, and a slanted hole plate 801 is installed on the upper end of the support rod 8.

[0050] In practical application, when the extruded plastic blocks fall downwards, they first land on the inclined perforated plate 801, then roll forward on the inclined perforated plate 801. Finally, the waste plastic can be quickly dried by a vibrating dryer, and then melted for processing and reuse.

[0051] like Figure 2 and 3As shown, in one embodiment, a baffle plate 104 is installed at the upper end of the base 1, and a drain pipe 105 is installed at the lower end of the base 1.

[0052] In practical application, the water discharged from the flushing component 3 and the water removal component 4 falls onto the base 1, is blocked by the baffle plate 104, and is finally discharged and collected through the drain pipe 105, and then recycled through the sewage treatment system.

[0053] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.
