Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and in particular to a device for recycling and processing excess waste from plastic production. Background Art

[0002] When using molds to make plastic products, some burrs will remain on the edges after the plastic products are formed, and a plastic head connected to the mold will be left at the feed hole of the mold. The burrs, plastic heads and other plastic waste need to be cut off. In order to prevent waste, these plastic wastes will be recycled and reused.

[0003] At present, in order to save energy, plastic waste is generally collected and processed in a centralized manner after a certain amount has been collected. During the collection process, the plastic waste will accumulate and collect dust, and plastic products may adhere to oil during the production process. In the process of recycling plastic waste, oil and dust are recycled together with the plastic waste, and the dust is processed together with the reused plastic, which may cause quality problems of the recycled plastic. Therefore, the plastic waste needs to be sent to the cleaning equipment for cleaning to remove the oil and dust on its surface, so as to ensure the quality of the plastic products after reprocessing.

[0004] In the cleaning process, existing methods are mainly divided into two categories: the first method is to evenly spread the plastic waste on a mesh conveyor belt and use a high-pressure water gun to wash it vigorously; however, this method has an obvious disadvantage: the plastic waste on the conveyor belt tends to stack together, making it difficult for the high-pressure water gun to fully and thoroughly wash each piece of plastic, resulting in stains remaining on some fragments.

[0005] Another method is to place the plastic waste into a bucket filled with cleaning fluid and use a motor-driven stirring rod to stir and clean the fragments. Although this method can make the plastic waste fully contact with the cleaning fluid, it also has problems: since some plastic waste will float on the water surface, it is difficult to effectively remove stubborn stains attached to the fragments by simply relying on stirring, resulting in poor cleaning effect.

[0006] Although these two methods have their own characteristics, they both have the problem of incomplete cleaning to varying degrees, which affects the reprocessing quality and utilization rate of plastic waste.

[0007] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0042] like Figures 1 to 12 As shown, the present invention provides a device for recycling and processing excess waste from plastic production, comprising: a cleaning box 1; a cleaning mechanism 2 for cleaning the plastic waste; and a pre-treatment mechanism 3 for treating the plastic waste before cleaning.

[0043] The cleaning mechanism 2 includes: a rotating drum 21 rotatably installed in the cleaning box 1, a power source 22 that drives the rotating drum 21 to rotate, a rotating plate 23 fixedly connected to the end of the rotating drum 21, and a stirring plate 24 fixedly installed on the rotating drum 21. There are multiple stirring plates 24, and each stirring plate 24 is provided with multiple water filter grooves 27. The size of the water filter grooves 27 is smaller than the thickness of the plastic waste, so that the inner cavity of the water filter grooves 27 can pass through the cleaning liquid, and the plastic waste cannot enter the inner cavity of the water filter grooves 27, a cleaning part 25 installed on the stirring plate 24, and a flushing component 26 for flushing the plastic waste; the rotating plate 23 is rotatably installed on the cleaning box 1.

[0044] When cleaning plastic waste, first add a proper amount of cleaning liquid into the cleaning box 1 to clean the dust and oil stains on the surface of the plastic, and the liquid level of the cleaning liquid does not exceed the axis of the rotating drum 21.

[0045] The pretreated plastic waste is transported to the cleaning box 1 through the pretreatment mechanism 3. At the same time, the power source 22 is started to drive the rotating drum 21 to rotate, and the rotating drum 21 drives the stirring plate 24 to rotate. When the stirring plate 24 rotates, it can drive the plastic waste into the cleaning liquid, and then take the plastic waste out of the cleaning liquid. The stirring plate 24 drives the plastic waste to continuously move in the cleaning liquid, so that the cleaning liquid has an impact on the plastic waste, thereby achieving preliminary cleaning of dust or oil stains on the surface of the plastic waste, so that the surface of the plastic waste is cleaned, and the cleanliness of the plastic waste is improved.

[0046] Furthermore, a plurality of stirring plates 24 are provided, so that the plastic waste can be divided into multiple portions for cleaning, thereby preventing a large amount of plastic waste from piling up together, resulting in inadequate cleaning.

[0047] It is to be added here that the power source 22 is preferably: a motor.

[0048] The flushing assembly 26 includes: a pump body 261 fixedly installed on the cleaning tank 1, a liquid inlet pipe 262 connecting the liquid inlet end of the pump body 261 and the cleaning tank 1, a liquid collecting pipe 264 fixedly installed in the cleaning tank 1, a liquid spray head 265 plugged into the liquid collecting pipe 264, and a liquid outlet pipe 263 connecting the liquid outlet end of the pump body 261 and the liquid collecting pipe 264.

[0049] While the stirring plate 24 drives the plastic waste to be cleaned in the cleaning liquid, the pump body 261 is started. At this time, the cleaning liquid in the cleaning box 1 can be sucked in through the liquid inlet pipe 262, and transported to the collecting pipe 264 through the liquid outlet pipe 263, and then sprayed out through the spray head 265 connected to the collecting pipe 264.

[0050] Since there are multiple spray heads 265, which are linearly distributed in the corresponding collecting pipes 264, and the spray heads 265 all point to the rotating drum 21, when the stirring plate 24 drives the plastic waste to be removed from the cleaning liquid, the cleaning liquid sprayed by the spray head 265 can flush the plastic waste. Since the cleaning liquid sprayed from the spray head 265 flows at a high speed, the stubborn oil or dust on the surface of the plastic waste can be washed away, thereby achieving secondary cleaning of the dust or oil stains on the surface of the plastic waste, further improving the cleanliness of the plastic waste.

[0051] In addition, due to the start-up of the pump body 261, the cleaning liquid forms a circulation flow. At this time, a filtering device can be installed at the liquid inlet end of the pump body 261. While the cleaning liquid is circulating, the impurities in the cleaning liquid are filtered to avoid excessive impurities in the cleaning liquid that affect the cleaning effect.

[0052] The cleaning member 25 includes: a mounting groove provided on the stirring plate 24, an active roller 251 and a driven roller 252 rotatably mounted in the mounting groove, a transmission belt 253 installed between the active roller 251 and the driven roller 252, bristles (not shown) fixedly mounted on the surface of the transmission belt 253, a linkage gear 254 rotatably mounted on the rotating plate 23, and a gear ring 255 meshingly connected to the linkage gear 254; the gear ring 255 is fixedly mounted on the cleaning box 1; the linkage gear 254 is coaxially connected to the active roller 251.

[0053] When the stirring plate 24 rotates, the cleaning member 25 and the rotating plate 23 can be driven to rotate, thereby driving the linkage gear 254 to rotate. Since the linkage gear 254 and the gear ring 255 are meshed with each other, the linkage gear 254 rotates along the circumference of the rotating drum 21 while rotating, thereby driving the active roller 251 to rotate, and further driving the transmission belt 253 to rotate. The surface of the transmission belt 253 is provided with bristles. When the plastic waste contacts the transmission belt 253, the surface of the plastic waste can be brushed, thereby achieving the re-cleaning of dust or oil stains on the surface of the plastic waste, further improving the cleanliness of the plastic waste.

[0054] Furthermore, the rotation of the transmission belt 253 can drive the plastic waste to move, thereby preventing the plastic waste from adhering to the stirring plate 24 and causing inadequate cleaning of the plastic waste.

[0055] It should be added that a sealing door is also installed on the cleaning box 1. After the plastic waste is cleaned, the stirring plate 24 drives the plastic waste to rotate to the sealing door. At this time, the sealing door is opened and the staff can take out the cleaned plastic waste.

[0056] In the present invention, through the setting of the cleaning mechanism 2, the plastic waste can be stirred, rinsed and brushed, thereby achieving multiple cleaning of the plastic waste, greatly improving the cleanliness of the plastic waste, and solving the problem that the existing cleaning methods have incomplete cleaning to varying degrees, affecting the reprocessing quality and utilization rate of the plastic waste.

[0057] Since the plastic waste contains large pieces of plastic, which are difficult to stir and separate during cleaning, and easily lead to inadequate cleaning, a pre-treatment mechanism 3 is provided to crush the plastic waste.

[0058] The pre-processing mechanism 3 includes: a processing box 31, a crushing assembly 32 for crushing the plastic waste, a material guide assembly 33 for guiding the plastic waste to the crushing assembly 32, a dust removal assembly 34 for removing dust when the plastic waste is crushed, and a spray assembly 35 for spraying a cleaning agent on the plastic waste; the crushing assembly 32 includes: a crushing roller 321 rotatably installed in the processing box 31, the crushing roller 321 is provided with two power sources 322 for driving the crushing roller 321 to rotate, and the power source 322 is fixedly installed. On the processing box 31, the output shaft of the power source 2 322 is coaxially connected to any one of the crushing rollers 321, and the driving gear 323 is coaxially connected to the crushing roller 321. The two driving gears 323 are meshed with each other to guide the crushed plastic waste to the inclined plate 325 in the cleaning box 1. A discharge opening is provided on the processing box 31, and the discharge side of the inclined plate 325 passes through the inner cavity of the discharge opening. The inclined plate 325 is provided with a plurality of through holes and a cleaning piece 324 for cleaning the crushing roller 321.

[0059] The plastic waste is placed into the processing box 31 through the top opening of the processing box 31. At this time, the power source 2 322 is started to drive the crushing roller 321 to rotate, and the crushing roller 321 drives the adjacent driving gear 323 to rotate. Since the two driving gears 323 are meshed with each other, the two crushing rollers 321 rotate relative to each other, thereby crushing the plastic waste. The crushed plastic waste falls downward from between the two crushing rollers 321 onto the inclined plate 325, and slides through the inclined plate 325 into the cleaning box 1.

[0060] It is to be added here that the second power source 322 is preferably: a motor.

[0061] In the present invention, the setting of the crushing component 32 can crush the plastic waste and reduce the volume of the plastic waste. The crushed plastic waste is more easily penetrated and cleaned by the cleaning liquid, which helps to remove stains and impurities attached to the plastic surface. At the same time, small pieces of plastic waste are also more easily stirred and separated during the cleaning process, thereby improving the cleaning efficiency.

[0062] The cleaning member 324 includes a brush roller 3242 rotatably installed in the processing box 31 and a driven gear 3241 coaxially connected to the brush roller 3242 .

[0063] When the driving gear 323 rotates, it can drive the driven gear 3241 to rotate, and the driven gear 3241 drives the brush roller 3242 to rotate. The bristles on the brush roller 3242 can, on the one hand, clean the impurities attached to the surface of the brush roller 3242, ensuring the pulverizing effect of the brush roller 3242 on the plastic waste. On the other hand, it can knock off the plastic waste stuck on the pulverizing roller 321, avoiding the plastic waste stuck on the pulverizing roller 321 from rotating with the pulverizing roller 321 and affecting the normal use of the pulverizing roller 321, further ensuring the pulverizing effect of the pulverizing roller 321 on the plastic waste.

[0064] The material guide assembly 33 includes: a material guide plate 331 hingedly installed in the processing box 31, a cam 332 rotatably installed in the processing box 31, a driven pulley 335 coaxially connected to the cam 332, a driving pulley 333 coaxially connected to the driven gear 3241, a linkage belt 334 installed between the driving pulley 333 and the driven pulley 335, and a reset member 336 for driving the material guide plate 331 to reset; the reset member 336 includes: a mounting shell 3361 fixedly installed in the processing box 31, a sliding rod 3362 fixedly installed in the mounting shell 3361, a slider 3363 slidably installed on the sliding rod 3362, a linkage rod 3365 hingedly installed between the slider 3363 and the material guide plate 331, and a reset spring 3364 for driving the material guide plate 331 to reset; one end of the reset spring 3364 is fixedly connected to the slider 3363, and the other end of the reset spring 3364 is fixedly connected to the inner wall of the mounting shell 3361.

[0065] Put the plastic waste into the processing box 31 from the top opening, then start the power source 2 322, which drives the driven gear 3241 to rotate, the driven gear 3241 drives the driving pulley 333 to rotate, the driving pulley 333 drives the interlocking belt 334 to rotate, the interlocking belt 334 drives the driven pulley 335 to rotate, thereby driving the cam 332 to rotate, when the cam 332 rotates and squeezes the guide plate 331, driving the guide plate 331 to rotate at its hinge with the processing box 31, the guide plate 331 drives the interlocking rod 3365 to move, and the interlocking rod 3365 drives the slider 3363 to the mounting shell 3361 When the cam 332 is separated from the guide plate 331, the slider 3363 is reset by the elastic force of the reset spring 3364, and the slider 3363 drives the connecting rod 3365 to reset, thereby driving the guide plate 331 to reset. The cam 332 and the reset member 336 cooperate with each other to make the guide plate 331 vibrate, thereby driving the plastic waste to shake, and then the plastic waste can be easily guided between the two crushing rollers 321, thereby avoiding the problem that too much plastic waste is easily accumulated and stuck between the two guide plates 331, thereby improving the feeding efficiency.

[0066] The dust removal assembly 34 includes: a cover plate 341 slidably mounted on the processing box 31, the cover plate 341 is provided with two pieces, a connecting plate 342 fixedly mounted on the cover plate 341, a limiting shell 343 fixedly mounted on the processing box 31, a power source 344 that drives the connecting plate 342 to slide in the limiting shell 343, and a dust collection unit 345 for removing dust generated when plastic waste is crushed.

[0067] When it is necessary to put plastic waste into the processing box 31, the power source 344 is started to drive the two connecting plates 342 to move, and the connecting plates 342 drive the adjacent cover plates 341 to move away from each other, so that the two cover plates 341 do not have a sealing effect on the processing box 31. At this time, an appropriate amount of plastic waste can be put in through the top opening of the processing box 31.

[0068] When the plastic waste is crushed, the power source 344 is started to drive the connecting plate 342 to reset, and the connecting plate 342 drives the adjacent cover plates 341 to reset close to each other, so that the two cover plates 341 close the processing box 31 again, thereby preventing the dust generated during the crushing from floating out from the top opening of the processing box 31 and causing pollution to the production ring.

[0069] It is to be added here that the power source three 344 is preferably: a cylinder.

[0070] At the same time, the dust collection unit 345 is started to remove the dust in the processing box 31. The dust collection unit 345 includes: an air pump 3451 fixedly installed on the processing box 31, an air inlet pipe 3452 connecting the air inlet end of the air pump 3451 and the processing box 31, an air outlet pipe 3453 connecting the air outlet end of the air pump 3451 and the processing box 31, and a filter 3455 for filtering the gas during the air intake of the air pump 3451. The filter 3455 is installed in the processing box 31 and a collecting hopper 3454 fixedly installed in the processing box 31.

[0071] Specifically, by starting the air pump 3451, the air at the bottom of the inner cavity of the processing box 31 can be sucked out through the air inlet pipe 3452 and blown into the top of the processing box 31 through the air outlet pipe 3453. When the air at the bottom of the inner cavity of the processing box 31 is sucked out, the air in the processing box 31 flows downward through the collecting hopper 3454, and the dust generated when the plastic waste is crushed floats downward with the air flow. Through the setting of the filter 3455, the dust in the gas can be filtered, so that the air discharged from the air outlet pipe 3453 is clean gas, and the dust is retained on the top of the filter 3455. The gas blown out through the air outlet pipe 3453 can blow up the dust attached to the top of the inner cavity of the processing box 31, so that the dust floats downward with the air flow and is filtered and collected.

[0072] Due to the operation of the air pump 3451, the air circulation in the processing box 31 is accelerated, thereby improving the dust collection efficiency.

[0073] Through the setting of the collecting hopper 3454, when the dust passes through the collecting hopper 3454, it is not easy to float upward due to the obstruction of the collecting hopper 3454, which is conducive to the collection of the dust.

[0074] In addition, during the crushing process, the dust on the surface of the plastic waste will also be separated as the plastic waste vibrates and collides, and the dust collection unit 345 also collects this part of the dust, thereby having a certain cleaning effect on the plastic waste, which is beneficial to subsequent cleaning.

[0075] It should be added here that the filter 3455 is configured to be detachable, and a movable door (not shown) is installed on the side wall of the processing box 31. When it is necessary to clean the dust on the filter 3455 or replace the filter 3455, the movable door can be opened for cleaning or replacement.

[0076] The spray assembly 35 includes: a fixed cylinder 351 fixedly installed in the limiting shell 343, the fixed cylinder 351 is connected to a liquid storage tank, the liquid storage tank stores detergent, a first one-way valve is installed between the fixed cylinder 351 and the liquid storage tank, a piston 352 slidably installed in the fixed cylinder 351, a movable rod 353 fixedly installed between the piston 352 and the connecting plate 342, the movable rod 353 passes through the inner cavity of the fixed cylinder 351, and the movable rod 353 is installed with a sealing ring at the penetration point of the fixed cylinder 351 to reduce gas leakage from the penetration point of the fixed cylinder 351 when the movable rod 353 moves, a distribution pipe 355 rotatably installed in the processing box 31, an atomizing nozzle 356 plugged and installed on the distribution pipe 355, a liquid guide pipe 354 connecting the distribution pipe 355 and the fixed cylinder 351, the liquid guide pipe 354 is installed with a second one-way valve, and a swing unit 357 for driving the distribution pipe 355 to swing.

[0077] The fixed cylinder 351 is divided into two independent spaces by the piston 352, one space storing the detergent and the other space storing the air.

[0078] When the power source three 344 drives the two connecting plates 342 away from each other, the connecting plates 342 drive the adjacent movable rods 353 to move, and the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinder 351. At this time, the first one-way valve opens and the second one-way valve closes, and the detergent in the liquid storage tank is sucked into the fixed cylinder 351.

[0079] When the power source three 344 drives the two connecting plates 342 to approach each other, the connecting plates 342 drive the adjacent movable rods 353 to move, and the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinder 351. At this time, the first one-way valve is closed and the second one-way valve is opened. The detergent in the fixed cylinder 351 is transported to the liquid distribution pipe 355 through the liquid guide tube 354 and is atomized and sprayed out through the atomizing nozzle 356. The atomized detergent is sprayed on the surface of the plastic waste, so that the detergent is evenly attached to the surface of the plastic waste, thereby decomposing the oil and dust on the plastic waste, realizing pre-cleaning before cleaning, which is conducive to more thorough cleaning by the subsequent cleaning mechanism 2, and further improving the cleanliness of the plastic waste cleaning.

[0080] At the same time, the swing unit 357 drives the dispensing tube 355 to swing, and then drives the atomizing nozzle 356 to swing. The swing unit 357 includes: a transmission gear 3571 coaxially connected to the dispensing tube 355, a rack 3572 meshing with the transmission gear 3571, a guide shell 3573 for guiding the rack 3572 when it moves, and a linkage spring 3574 for driving the rack 3572 to reset. One end of the linkage spring 3574 is fixedly connected to the rack 3572, and the other end of the linkage spring 3574 is fixedly connected to the inner wall of the guide shell 3573, and a half gear 3575 coaxially connected to the driven gear 3241.

[0081] Specifically, when the driven gear 3241 rotates, it drives the half gear 3575 to rotate. When the half gear 3575 rotates and engages with the rack 3572, it drives the rack 3572 to slide in the guide housing 3573 and causes the linkage spring 3574 to deform. When the rack 3572 moves, it drives the transmission gear 3571 to rotate, thereby driving the liquid dispensing tube 355 to rotate. The liquid dispensing tube 355 drives the atomizing nozzle 356 to rotate.

[0082] When the half gear 3575 rotates and separates from the rack 3572 , the rack 3572 is driven to return to its original position under the action of the linkage spring 3574 , and the rack 3572 drives the transmission gear 3571 to rotate in the opposite direction, thereby driving the reverse atomizing nozzle 356 to rotate.

[0083] The present invention can drive the atomizing nozzle 356 to swing back and forth through the setting of the swing unit 357, thereby expanding the spray range of the atomizing nozzle 356, thereby spraying the plastic waste more comprehensively and improving the effect of pre-cleaning the surface of the plastic waste.

[0084] The pretreatment mechanism 3 also includes: an air collecting pipe 37 rotatably installed in the treatment box 31, a nozzle 38 plugged into the air collecting pipe 37, an air guide pipe 36 connecting the air collecting pipe 37 and the fixed cylinder 351, and a connecting gear 39 coaxially connected to the air collecting pipe 37; the connecting gear 39 and the rack 3572 are arranged to mesh with each other.

[0085] When the power source three 344 drives the two connecting plates 342 away from each other, the connecting plates 342 drive the adjacent movable rods 353 to move, and the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinder 351, which can squeeze the gas in the fixed cylinder 351 and transport it to the gas collecting pipe 37 through the air guide pipe 36, and spray it out through the nozzle 38. The gas is sprayed on the bottom of the inclined plate 325, so that the through holes on the inclined plate 325 can be cleaned to avoid dust clogging the through holes when the crushing starts, affecting the air flow in the processing box 31.

[0086] When the power source 344 drives the two connecting plates 342 to approach each other, the connecting plates 342 drive the adjacent movable rods 353 to move, and the movable rods 353 drive the adjacent pistons 352 to slide in the fixed cylinder 351, so that gas can be sucked into the fixed cylinder 351 to prepare for subsequent use.

[0087] At the same time, the reciprocating movement of the rack 3572 can drive the connecting gear 39 to rotate back and forth, and then drive the air collecting pipe 37 to swing back and forth, thereby expanding the injection range of the injection head 38, and then the through holes on the inclined plate 325 can be fully cleaned, thereby improving the cleaning effect.
