Description

Technical Field

[0001] This invention belongs to the field of plastic waste recycling technology, specifically relating to a waste recycling and processing device for PE film production. Background Technology

[0002] PE film, or polyethylene film, is a widely used plastic material with many excellent properties, such as good mechanical strength, chemical resistance, moisture resistance, and transparency. Therefore, it is widely used in packaging, agriculture, construction, and other fields. The production process of PE film generates waste such as scraps and defective products. Waste recycling is an important step, which not only helps reduce environmental pollution but also lowers production costs. An effective waste recycling system can reprocess waste PE film into usable materials, maximizing resource utilization. However, these wastes may contain impurities such as dust, metal shavings, and plastic particles, making them unsuitable for direct melting.

[0003] A Chinese patent document with publication number CN118650775B proposes a waste recycling device based on the injection molding of plastic parts for thermos cups. This device employs a cleaning mechanism where scrap materials are poured into a cleaning tank along with cleaning fluid. A servo motor drives a rotating column to rotate, causing brushes to agitate the plastic waste in the tank, removing attached grease. The rotation of the rotating column then drives a disc to rotate, which, through a conveyor belt, drives another rotating column to rotate, scraping away stubborn paint and stickers from the plastic waste located between two clamping plates. However, PE film waste is a sheet-like film, making traditional brush cleaning methods difficult to effectively clean and potentially leading to entanglement and blockage, hindering subsequent collection and melting processes.

[0004] Therefore, this invention proposes a waste recycling and processing device for PE film production, which solves the problem in the prior art that traditional brush cleaning methods are difficult to effectively clean because PE film waste is in sheet form, which may lead to entanglement and blockage, hindering subsequent collection and melting processing. The device combines ultrasonic cleaning with a conveying component, directly crushing and turning large sheets of film during the cleaning stage to ensure complete cleaning. Combined with drying and melting components, it integrates cleaning, crushing, drying, melting, and recycling, optimizing the PE film waste recycling process, improving efficiency, and reducing costs.

A conveying mounting platform 251 is installed on the drive chain of the conveyor chain assembly 25. The upper surface of the conveyor chain assembly 25 is provided with mounting grooves that are compatible with the telescopic mounting rods 32. Limiting guide rail 1 252 and limiting guide rail 253 are provided above the side surface of the inner processing box 21. A heating chamber 221 is installed on the side of the trapezoidal barrier frame 22 away from the ultrasonic cleaning chamber 23. A PE film waste melting and recycling pot 223 is installed above the heating chamber 221. Heating pipes 222 are symmetrically arranged inside the heating chamber 221. A melting and extrusion chamber 225 is fixedly installed below the PE film waste melting and recycling pot 223. The trapezoidal barrier frame 22 is located near... A heat recovery chamber 224 is located on the side near the ultrasonic cleaning chamber 23. An exhaust trough 2231 is provided on the inner wall of the PE film waste melting and recovery pot 223 on the side away from the heat recovery chamber 224. A melting stirrer 2232 is located in the middle of the PE film waste melting and recovery pot 223. An air inlet trough 2241 is provided on the inner wall of the heat recovery chamber 224 near the heating chamber 221. A gas purification chamber 2242 is located on one side of the air inlet trough 2241. A circulating fan 2243 is located on one side of the gas purification chamber 2242. The air inlet pipe of the circulating fan 2243 is fixedly connected to the inner wall of the gas purification chamber 2242. A hot air pipe 2244 is fixedly installed on the air outlet pipe of the circulating fan 2243. A movable exhaust connector 224 is movably installed at the upper end of the hot air pipe 2244. 41. A magnetic ring 22442 is fixedly sleeved on the outer surface of the movable exhaust connector 22441. A screw extruder 2252 is installed inside the conveyor chain assembly 25. A pulley drive assembly that drives the screw extruder 2252 and the melting stirrer 2232 to rotate synchronously is installed on the outer surface of the inner processing box 21. A PE film melting and recovery pipe 2251 is fixedly installed at the bottom of one end of the melting extrusion chamber 225. An inlet penetrating the bottom inner wall of the PE film waste melting and recovery pot 223 is provided above the other end of the melting extrusion chamber 225. A filter screen is provided above the inlet. In this embodiment, it is worth noting that an air purification filter element is movably installed inside the gas purification chamber 2242, and a movable sealing baffle is provided at one end of the gas purification chamber 2242.The air purification filter inside the gas purification chamber 2242 is easily replaceable. The outer side of the integrated cleaning, drying, and melting treatment component 2 is equipped with a motor gear drive assembly that rotates the conveyor chain assembly 25. The trapezoidal barrier frame 22 rationally partitions the space inside the inner treatment box 21, separating it into an ultrasonic cleaning chamber 23, a heating chamber 221, and a heat recovery chamber 224. A waste collection cleaning tank 31 is provided. The ultrasonic cleaning chamber 23 can store cleaning fluid. The waste material is first placed inside the ultrasonic cleaning chamber 23. The ultrasonic generator 24 uses ultrasonic waves to generate bubbles. The high-speed micro-jet generated by the bubble collapse effectively breaks down and peels off the dirt particles adhering to the surface of the PE film waste. The cleaning speed is fast and the effect is good, completing the cleaning of PE film waste in a short time. The cleaning task of the waste material reduces labor and time costs. The waste collection cleaning tank 31 collects the PE film waste. The telescopic mounting rod 32 is connected to the conveyor mounting platform 251 and suspended inside the ultrasonic cleaning chamber 23 to avoid the bottom from contacting the bottom of the tank. This ensures that the surface of the PE film waste can be fully cleaned by ultrasonic waves and cleaning solution. After cleaning, the waste material is gradually raised along the inclined surface of the trapezoidal barrier frame 22 by the conveyor chain assembly 25. The first limiting guide rail 252 supports and limits the conveyor mounting platform 251 during the upward movement. At this time, the telescopic mounting rod 32 slowly retracts until the hollow rotating rod 33 is above the second limiting guide rail 253, draining the cleaning solution inside the waste collection cleaning tank 31. At this time, the heating pipe inside the heating chamber 221... The circulating fan 2243 inside the heat recovery chamber 222 and the heating pipe 222 starts working, heating the air inside the heating chamber 221, and preheating the PE film waste melting and recovery pot 223 and the melting and extrusion chamber 225. The circulating fan 2243 causes the airflow to enter the heating chamber 221 through the exhaust channel 2231, be heated, and then enter the gas purification chamber 2242 through the air inlet channel 2241. Finally, it is drawn out by the circulating fan 2243 and transported through the hot air pipe 2244 to the hollow rotating rod 33 inside the waste collection and washing tank 31 to fully dry the PE film waste inside the waste collection and washing tank 31. This hot air drying system design has two main advantages: firstly, the heating pipe 222 heats the air inside the heat recovery chamber 221, and secondly, the heating pipe 222 heats the air inside the heat recovery chamber 221, and then preheats the PE film waste melting and recovery pot 223 and the melting and extrusion chamber 225. During heating, both the PE film waste melting and recycling pot 223 and the melting extrusion chamber 225 are preheated simultaneously. This facilitates the melting of the dried waste material before it is fed into the PE film waste melting and recycling pot 223, shortening the melting time. Secondly, by designing the airflow direction, air enters the heating chamber 221 through the exhaust channel 2231, is heated, and then enters the gas purification chamber 2242 through the air inlet channel 2241. The air purification filter inside the gas purification chamber 2242 can purify the air and absorb the odor generated by the melting of plastic, achieving the purpose of recovering heat to dry the waste material and saving energy. At the same time, it can also treat the odor. After the waste is dried, it is collected and transported by the waste collection and washing tank 31 to the top of the PE film waste melting and recycling pot 223.Waste materials are fed into the PE film waste melting and recycling pot 223 for thermal melting to form a liquid. The liquid then enters the melting and extrusion chamber 225 through the inlet on the bottom inner wall of the pot 223. The rotating screw extruder 2252 forces the plastic solution through the PE film melting and recycling pipe 2251 for recycling into other products. The screw extruder 2252 and the melting agitator 2232 are driven synchronously by a pulley assembly, ensuring the waste is melted, agitated, and extruded simultaneously, thus improving waste processing efficiency.

[0035] Example 2, please refer to Figures 1 to 14 Based on Embodiment 1, in order to improve the efficiency of waste treatment, this embodiment further proposes that the top surface of the waste centralized cleaning tank 31 is provided with an impurity overflow groove 312, and one end of the waste centralized cleaning tank 31 is provided with an impurity overflow groove 313. Arc-shaped flip plates 311 are symmetrically hinged on both sides of the upper part of the waste centralized cleaning tank 31. The bottom side surfaces of the two sets of arc-shaped flip plates 311 are in contact with each other through magnetic sheets. Telescopic rods 4 are symmetrically and movably installed above the inner processing box 21. Magnetic adsorption strips 41 are hinged to the output end of the telescopic rods 4. The two sets of telescopic rods 4 are set on the PE film waste melting and recycling pot 223. In this embodiment, when the waste collection cleaning tank 31 is conveyed to the PE film waste melting and recycling pot 223 by the conveying installation platform 251 and the conveyor chain assembly 25, the telescopic rod 4 works to make the magnetic adsorption strip 41 contact and adsorb the arc-shaped flip plates 311 on both sides. Then, the telescopic rod 4 retracts to make the arc-shaped flip plates 311 flipped, so that the waste inside the waste collection cleaning tank 31 is automatically put into the PE film waste melting and recycling pot 223, improving the processing efficiency. The design of the impurity overflow tank 1 312 and the impurity overflow tank 2 313 is mainly to facilitate the overflow of impurities and dirt during ultrasonic cleaning.

[0036] Example 3, please refer to Figures 1 to 14Based on Embodiment 2, to ensure the waste material is thoroughly dried during the drying process, this embodiment further proposes that magnetic rings 331 are fixedly fitted onto the outer surfaces of both ends of the hollow rotating rod 33. A cutting blade 35 is fixedly mounted on the outer surface of the hollow rotating rod 33 by bolts. A hollow turning rod 34 is fixedly mounted on the outer surface of the hollow rotating rod 33, with the hollow turning rod 34 and the cutting blade 35 alternating. A fixed ball 341 is fixedly mounted inside the hollow turning rod 34, and a compression ball 342 is movably mounted on the side wall of the hollow turning rod 34. A through hole with a diameter slightly larger than that of the compression ball 342 is provided on the inner wall of the hollow turning rod 34. A sealing plate is fixedly mounted on one end of the compression ball 342, and a spring is fixedly mounted between the sealing plate and the outer surface of the fixed ball 341. Rod 343; In this embodiment, it is worth noting that the hollow turning rod 34 and the cutting blade 35 are distributed in a spiral pattern on the outer surface of the hollow rotating rod 33. Small holes are evenly distributed on the surface of the hollow rotating rod 33. When the waste collection and cleaning tank 31 is conveyed to the highest point of the trapezoidal barrier frame 22 by the conveying installation platform 251 and the conveying chain assembly 25, the position of the hot air pipe 2244 corresponds exactly to the position of the hollow rotating rod 33. At this time, the magnetic ring 22442 outside the movable exhaust connector 22441 fits exactly with the magnetic ring 331, so that the hot air is conveyed into the interior of the hollow rotating rod 33 and discharged through the surface of the hollow rotating rod 33 and the hollow turning rod 34, so as to evenly dry the waste, making the waste dry more fully and saving drying time.

[0037] Example 4, please refer to Figures 1 to 14Based on Embodiment 3, to improve the efficiency of waste cleaning and drying, this embodiment further proposes that rotating disks 231 are rotatably installed on both sides of the ultrasonic cleaning chamber 23, and magnetic rings 232 are fixedly installed inside both sets of rotating disks 231. One set of rotating disks 231 is located on the opposite side of the air inlet slot 2241. In this embodiment, drive motors that drive the two sets of rotating disks 231 to rotate are fixedly installed on the outer surface of the inner processing box 21. When the waste collection cleaning tank 31 is in the ultrasonic cleaning chamber 23, the rotation is achieved by rotating disks 231. At a low position, the rotating disk 231 below the ultrasonic cleaning chamber 23 is attached to the magnetic ring 331 via magnetic ring 232. At this time, the motor can drive the rotating disk 231 and the hollow rotating rod 33 to rotate at a low speed simultaneously. The rotation of the hollow rotating rod 33 not only allows the cutting blade 35 to properly cut large pieces of waste material so that they are thoroughly cleaned, but also the rotation of the hollow turning rod 34 promotes the turning of the waste material, allowing the waste material to be separated and ensuring that each piece of waste material is thoroughly cleaned. At this time, due to the buoyancy of the cleaning fluid, the fixed ball 34... 1. No compression occurs between the fixed ball 341 and the waste material. Under the compression of the spring rod 343, the through holes on the surface of the hollow rotating rod 34 are sealed to prevent cleaning fluid and impurities from entering. When the waste material collection cleaning tank 31 is at the highest point of the trapezoidal barrier frame 22, the hollow rotating rod 33 is in contact with the hot air pipe 2244. The rotating disk 231 above the ultrasonic cleaning chamber 23 is also in contact with the magnetic ring 331 through the magnetic ring 232. Driven by the motor, the rotating disk 231 and the hollow rotating rod 33 rotate at low speed simultaneously during hot air drying. At this time, the cutting blade 35 can continue to cut large pieces of waste appropriately to facilitate faster melting later. The hollow rotating rod 33 rotates while ventilating into the waste collection and cleaning tank 31. At the same time, the hollow turning rod 34 turns over, and the fixed ball 341 squeezes the waste. The fixed ball 341 retracts inward under the cooperation of the squeezing ball 342 and the spring rod 343. At this time, the sealing plate of the fixed ball 341 removes the blockage of the hollow turning rod 34, allowing the gas to be released directly between the waste, accelerating the drying of the waste.

[0038] Example 5, please refer to Figures 1 to 14Based on Example 4, this example also proposes a recycling method for a waste recycling device used in PE film production, including the following steps: Step 1, take out the waste collection and cleaning tank 31, open the arc-shaped flip plate 311 and evenly fill an appropriate amount of waste to be processed into the waste collection and cleaning tank 31, loosen the arc-shaped flip plate 311 to ensure it is properly closed, and then place the entire waste collection and cleaning tank 31 inside the ultrasonic cleaning chamber 23, ensuring that the telescopic mounting rod 32 and the conveyor chain assembly 25 are accurately engaged; Step 2, inject cleaning fluid into the ultrasonic cleaning chamber 23 through the water inlet pipe on one side of the inner treatment tank 21, and appropriately add suitable cleaning agent to ensure that the cleaning fluid submerges the waste collection and cleaning tank. In the first step, the ultrasonic generator 24 is activated to clean the waste collection tank 31. Simultaneously, the motor on the outside of the rotating disc 231 is started. During the cleaning process, the waste material is appropriately cut and agitated to ensure thorough cleaning. In the second step, after a period of cleaning, the conveyor chain assembly 25 drives the waste collection tank 31 to gradually rise along the inclined surface of the trapezoidal barrier frame 22. The telescopic mounting rod 32 slowly retracts until the hollow rotating rod 33 is above the limit guide rail 253, draining the cleaning fluid inside the waste collection tank 31. At this time, the heating pipe 222 and heat recovery chamber 224 are activated. The heating pipe 222 heats the air inside the heating chamber 221. In the first step, the PE film waste melting and recycling pot 223 and the melting and extrusion chamber 225 are preheated. The circulating fan 2243 operates to direct the airflow through the exhaust channel 2231 into the heating chamber 221, where it is heated. Then, it enters the gas purification chamber 2242 through the air inlet channel 2241 and is finally extracted by the circulating fan 2243 and transported through the hot air pipe 2244 to the hollow rotating rod 33 inside the waste collection and cleaning tank 31 to fully dry the PE film waste that has been cleaned inside the waste collection and cleaning tank 31. In the fourth step, the conveyor chain assembly 25 continues to transport the waste collection and cleaning tank 31 to above the PE film waste melting and recycling pot 223. The telescopic rod 4 operates to make the magnetic adsorption strip 41... The arc-shaped flip plates 311 on both sides make contact adsorption, and then the telescopic rod 4 retracts to drive the arc-shaped flip plates 311 to flip, so that the waste inside the waste collection and cleaning tank 31 is automatically put into the PE film waste melting and recycling pot 223 for thermal melting to form liquid. The liquid enters the melting extrusion chamber 225 through the feed port on the bottom inner wall of the PE film waste melting and recycling pot 223. The spiral extruder 2252 rotates to discharge the plastic solution through the PE film melting and recycling pipe 2251 for recycling to produce other products. After the waste is put in, the cover on the top of the PE film waste recycling and processing box 1 is opened, the empty waste collection and cleaning tank 31 is taken out, and the next round of waste filling installation is carried out.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
