Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a device for the comprehensive recycling and treatment of waste materials from plastic product processing. Background Technology

[0002] With the rapid development of the plastics industry, the output of plastic waste has been increasing year by year, and its recycling and processing has become an important link in resource recycling and environmental protection. Plastic waste processing waste usually contains impurities such as dust, oil, and label adhesive, and comes in various shapes (such as flakes, blocks, films, bags, etc.). Traditional recycling and processing equipment has the following problems in the cleaning, dehydration and transportation processes.

[0003] With the development of industry technology, the research and development of plastic waste recycling technology is also constantly being improved. For example, Chinese patent with announcement number CN217664887U discloses a waste washing, crushing and pretreatment device for plastic production, which completes the conveying and washing of plastic waste through the cooperation of conveyor belt, small water pump and rotating roller.

[0004] While the aforementioned existing technologies can achieve automatic conveying and cleaning of plastic waste and improve the recycling efficiency of plastic waste, plastic products are ubiquitous in various industries. For example, plastic films, plastic woven bags, or other long strip or sheet-like flexible plastic products are prone to getting tangled on the rotating rollers during the cleaning process using the above technologies. Furthermore, simply rotating and agitating the water flow cannot efficiently clean the aforementioned plastic waste. The aforementioned plastic products, especially plastic films and plastic bags, tend to carry a large amount of moisture during the cleaning process, and putting them into the crusher after simple cleaning can easily damage the crusher.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-9 As shown in the embodiment of this application, a comprehensive recycling and treatment device for waste materials from plastic product processing is disclosed, including a base plate 1, a cleaning tank 2 is provided on the base plate 1, the cleaning tank 2 is used to hold cleaning liquid for cleaning plastic waste, a conveying module 5 is provided on the cleaning tank 2, the conveying module 5 is used to move the plastic waste, a cleaning module 3 and a dehydration module 4 are provided inside the cleaning tank 2, the cleaning module 3 and the dehydration module 4 perform cleaning and drying treatment on the plastic waste after cleaning before crushing.

[0031] The conveying module 5 includes a fixed bracket 51 installed on the cleaning tank 2, and a conveyor 52 is provided between the fixed bracket 51 and the cleaning tank 2.

[0032] The conveyor 52 includes a first conveyor shaft 521 mounted on the inner wall of the cleaning tank 2 via bearings. A second motor is mounted on the outer wall of the cleaning tank 2 via a motor mount. The second motor is connected to the first conveyor shaft 521 via a coupling. A second conveyor shaft 522 is mounted on the fixed bracket 51 via bearings. The first conveyor shaft 521 and the second conveyor shaft 522 are connected by a conveyor belt 523. A guide roller is mounted on the inner wall of the cleaning tank 2 via bearings. The guide roller is attached to the conveyor belt 523. Protective plates 524 are symmetrically arranged on the conveyor belt 523. A grid baffle 525 is evenly arranged between the two protective plates 524. Brushes are evenly arranged on the surface of the conveyor belt 523.

[0033] By adopting the above technical solution, the second motor drives the conveyor shaft 521 to rotate during operation. The conveyor shaft 521 drives the conveyor belt 523 to move synchronously through the cooperation between the second conveyor shaft 522 and the guide roller. The space formed between the two guard plates 524 and the grid baffle 525 can effectively isolate the plastic waste in the continuous processing process, thereby cooperating with the cleaning module 3 and the drying module 4 to carry out efficient cleaning of the plastic waste. The conveyor belt 523 is designed as a grid structure, and the inner wall of the cleaning box 2 is evenly equipped with upward spray pipes. When the rubbing plate 33 is working, the plastic waste is sprayed synchronously through the spray pipes so that the dust and debris in the cleaning process can be discharged with the flowing water.

[0034] The cleaning module 3 includes a mounting bracket 31 installed on the cleaning tank 2. A spray pipe can also be installed on the lower end face of the mounting bracket, or a water jetting pipe can be installed on the cleaning tank 2 to continuously spray water onto the plastic waste during the cleaning operation. A control branch chain 32 is installed on the mounting bracket 31, and a rubbing plate 33 is installed on the control branch chain 32. The rubbing plate 33 has a grid structure and a rubbing brush is installed on the rubbing plate 33.

[0035] The control branch 32 includes a control groove on the mounting frame 31. A control frame 321 is provided in the control groove through a sliding fit. A linkage frame 322 is slidably provided in the control frame 321. A linkage bracket 323 is slidably provided in the linkage frame 322. The linkage frame 322 and the linkage bracket 323 are slidably connected. A spring is provided between the linkage frame 322 and the linkage bracket 323. The upper end of the linkage bracket 323 is slidably connected to the guide frame 324. The guide frame 324 is provided on the mounting frame 31. A cylinder is provided on the mounting frame 31. The cylinder is connected to the control frame 321. The guide frame 324 includes an inclined part and a concave and convex part. In the initial state, the linkage bracket 323 is attached to the inclined part of the guide frame 324. The width of the guide frame 323 is the same as the width of the control groove.

[0036] The control frame 321 has symmetrical linkage holes, and a linkage rod 325 is movably installed in the linkage hole. The linkage rod 325 is connected to the linkage frame 322. Guide rails 326 are provided on the control slots at both ends of the linkage rod 325. The linkage rod 325 fits against the guide rails 326. The two guide rails 326 in the control slot are both concave and convex, and the concave and convex parts of the two guide rails 326 are designed to complement each other. When the control frame 321 moves in the control slot, the linkage rod 325 and the guide rails 326 cooperate to drive the linkage frame 322 to reciprocate left and right in the control frame 321.

[0037] By adopting the above technical solution, during the operation of the conveying module 5, the plastic waste in the cleaning box 2 is driven to move towards the rubbing plate 33. After the plastic waste moves to the working position of the rubbing plate, the branch chain 32 is controlled to work to drive the rubbing plate 33 to rub the plastic waste in the conveying module 5.

[0038] Specifically, firstly, the cylinder is activated to drive the control frame 321 to reciprocate within the control slot. During this movement, the control frame 321 simultaneously drives the linkage frame 323 in the linkage frame 322 to move along the inclined portion of the guide frame 324 towards the concave and convex portions.

[0039] During this process, the linkage frame 323 synchronously drives the rubbing plate 33 to move towards the plastic waste on the conveyor module 5. When the guide frame 324 moves to the position of the concave and convex part, the rubbing plate 33 can fit against the plastic waste. In this state, the cylinder drives the linkage frame 323 to reciprocate at the position of the concave and convex part of the guide frame 324, thereby controlling the rubbing plate 33 to rub and clean the plastic waste on the conveyor belt 523 back and forth. The design of the concave and convex part of the guide frame 324 allows the rubbing plate 33 to have up-down and back-and-forth movement adjustment during the reciprocating motion. In addition, with the mutual cooperation between the linkage rod 325 and the guide rail 326, the rubbing plate is synchronously controlled to adjust left and right. When the rubbing plate 33 is rubbed and cleaned by the multi-dimensional reciprocating motion, the multi-dimensional reciprocating motion of the rubbing plate 33 can perform efficient cleaning operations on the plastic waste.

[0040] The control frame 321 has guide holes at its corners, and guide frames 327 are slidably arranged in two adjacent guide holes. A spring is provided between the guide frame 327 and the control frame 321. The lower end of the guide frame 327 is connected to a cleaning frame 328. A rubbing plate 33 is arranged in the cleaning frame 328 by a spring. The upper end of the guide frame 327 is attached to the guide slide 329. The guide slide 329 is arranged on the mounting frame 31. The guide slide 329 has an inclined part and a horizontal part. The inclined part of the guide slide 329 is the same as the inclined part of the guide frame 324.

[0041] Using the above technical solution, during operation, when the cylinder drives the control frame 321 to the working state, the contact position between the guide frame 327 and the guide slide 329 moves from the inclined part to the horizontal part. During this process, the guide frame 327 synchronously drives the cleaning frame 328 to move towards the plastic waste. When the guide frame 327 moves to the horizontal position of the guide slide 329, the cleaning frame 328 and the conveyor belt 523 cooperate to form a rubbing working space. In addition, if the plastic waste is in bags or flakes, the cleaning frame 328 can also press and limit it during operation, so that the rubbing plate 33 can effectively rub and clean the plastic waste.

[0042] The dehydration module 4 includes a dehydration tank 41 mounted on the washing tank 2. A rotating tube 42 is mounted inside the dehydration tank 41 via a bearing. Adjustment grooves are evenly distributed along the circumference of the rotating tube 42. A drag claw 43 is mounted in the adjustment groove. A positioning frame 44 is mounted on the outer wall of the washing tank 2. An adjustment block 45 that cooperates with the drag claw 43 is mounted on the positioning frame 44. The adjustment block 45 has a circular part and a concave part. The adjustment block 45 is located inside the rotating tube 42. A motor is mounted on the rotating tube 42 via a coupling. The motor is fixed to the washing tank 2 via a motor mount.

[0043] By adopting the above technical solution, the motor is started during operation to control the rotation tube 42 to rotate. During the rotation of the rotation tube 42, the drag claw 43 is synchronously controlled. As the drag claw 43 follows the rotation tube 42, it works with the adjusting block 45 to change its working state. When the drag claw 43 rotates clockwise, it drags the cleaned plastic waste into the dehydration tank 41 and rotates clockwise. After the plastic waste is dehydrated, it is discharged from the dehydration tank 41 onto the conveying module 5. The conveying module 5 then sends the dehydrated plastic waste into the subsequent processing equipment.

[0044] An auxiliary frame 411 is provided on the inner wall of the dehydration tank 41, forming an installation cavity between the auxiliary frame 411 and the inner wall of the dehydration tank 41. Rotating shafts 412 are evenly arranged in the installation cavity, and cams 413 are provided on the rotating shafts 412. Pulleys are provided on the rotating shafts 412 located on the outside of the dehydration tank 41, and the pulleys are connected by a belt. One of the rotating shafts 412 is connected to the output shaft of motor three. Motor three is fixed on the outer wall of the dehydration tank 41. Auxiliary grooves are evenly opened on the auxiliary frame 411, and squeezing blocks 414 are slidably arranged in the auxiliary grooves. An auxiliary spring 415 is provided between the squeezing block 414 and the inner wall of the dehydration tank 41. A ventilation cavity can also be separated in the installation cavity by a partition. By opening air holes on the lower end face of the auxiliary frame 411, the ventilation cavity is connected to a fan during operation. The airflow generated by the fan during operation can act on the plastic waste through the air holes to increase the dehydration effect of the plastic waste.

[0045] The drag claw 43 includes a frame 431 and a claw rod 432. The frame 431 is disposed in the adjustment groove, the claw rod 432 is slidably disposed in the frame 431, a spring is provided between the claw rod 432 and the frame 431, and the claw rod 432 is attached to the adjustment block 45.

[0046] By adopting the above technical solution, the drag claw 43 changes its contact position with the adjusting block 45 during the rotation of the rotating tube 42, moving from the concave part of the adjusting block 45 towards the circular part. During this process, the claw rod 432 extends out from the frame 431, and after contacting the plastic waste on the conveyor belt 523 during rotation, the claw rod 432 can exert a dragging or pushing force on it. For products such as plastic bags or plastic films, the end of the claw rod 432 can penetrate into its interior. In operation, it cooperates with the grid baffle to control the plastic waste entering the dehydration tank 41. With the orderly rotation of the rotating tube 42, the plastic waste entering the dehydration tank 41 moves in the cavity formed between the rotating tube 42 and the auxiliary frame 411. During this process, the motor three is started. During operation, the cam 413 on the rotating shaft 412 is rotated by the cooperation between the pulley and the belt. During the rotation, the cam 413 cooperates with the auxiliary spring 415 to control the extrusion block 414 to move towards the rotating tube 42. The cooperation between the rotating tube 42 and the extrusion block 414 squeezes out a large amount of water from the plastic waste. Alternatively, high-pressure airflow can be used to improve the dehydration effect of the plastic waste. When the rotating tube 42 drives the claw rod 432 to move towards its concave part with the circular part of the adjusting block 45, the claw rod 432 retracts towards the frame 431. After the claw rod 432 is completely retracted into the frame 431, the dehydrated plastic waste falls onto the conveyor belt 523, and the conveying module 5 carries the dehydrated plastic waste into the subsequent processing machine.

[0047] The following steps are used in the process of treating plastic waste using this invention;

[0048] Step 1: Put the plastic waste to be processed into the washing tank 2;

[0049] Step 2: Conveying module 5 moves the plastic waste and isolates the continuously fed plastic waste during continuous operation;

[0050] Step 3: The plastic waste is rubbed and washed in multiple dimensions by the cleaning module 3, and then the large amount of water in the plastic waste is discharged by the dehydration module 4.

[0051] Step 4: The dehydrated plastic waste is fed into the plastic shredder through the conveying module 5 for crushing, and then the crushed plastic waste is fed into the plastic granulator for granulation processing.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
