Description

Technical Field

[0001] This utility model relates to the field of plastic waste recycling and treatment technology, and in particular to a device for recycling and treating waste materials from plastic product manufacturing. Background Technology

[0002] Waste generated during the production of plastic products, such as scraps, defective products, and sprues, must be recycled in a way that balances environmental friendliness, economic efficiency, and technical feasibility. The following are common recycling methods and their specific explanations: Waste is converted into recycled pellets through physical means (crushing, washing, sorting, melting, etc.) for reuse in production. For single-material, non-polluting waste (such as PP, PE, ABS, etc.); sorting can be used: classifying by material, color, and cleanliness to avoid mixing; crushing and washing: using a crusher to pulverize the waste and washing to remove oil, dust, and other impurities.

[0003] When cleaning oily and broken waste, the common method is to add the broken waste into a cylinder containing cleaning fluid, and then stir the waste and cleaning fluid using a stirring device. However, traditional recycling methods are not effective in cleaning waste. Either the cleaning is not thorough, leaving a lot of dirt and impurities on the surface of the waste, which affects the quality of subsequent reuse, or the cleaning device has a complex structure, is inconvenient to operate, and has low efficiency in the circulation and draining of the cleaning fluid, which cannot meet the needs of efficient and high-quality recycling.

[0004] Therefore, this application proposes a device for recycling and processing waste materials from the production of plastic products. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a device for recycling and processing waste materials from plastic product manufacturing.

Container cylinder. Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a device for recycling and processing waste materials from plastic product manufacturing, comprising: The cleaning tank 1 has a support 2 securely mounted at its bottom. The support 2 is made of high-strength material to ensure the stability of the device during operation. The cleaning tank 1 is made of corrosion-resistant and easy-to-clean stainless steel to meet the needs of various cleaning solutions and extend the service life of the equipment.

[0019] The cleaning mechanism is a key component of this device, including a water pump 3 mounted on one side of the support frame 2. The water pump 3 is a high-efficiency, energy-saving type, capable of adjusting flow rate and pressure according to cleaning needs to ensure effective circulation of the cleaning fluid. The water pump 3 is connected to the cleaning cylinder 1 via a piping structure, which includes a first T-joint pipe 4 and a second T-joint pipe 5 connected to the inlet and outlet of the water pump 3, respectively. Both the first T-joint pipe 4 and the second T-joint pipe 5 are connected to the cleaning cylinder 1 and the water pump 3 via quick-connect fittings, facilitating installation and disassembly while reducing the risk of leakage.

[0020] A first control valve 11 and a second control valve 12 are installed on the first three-way pipe 4 to control the inflow and outflow paths of the cleaning fluid, such as... Figure 1 As shown, this allows for the circulation or discharge of the cleaning fluid. Similarly, a third control valve 13 and a fourth control valve 14 are installed on the second three-way pipe 5. These two control valves are located on the second three-way pipe 5 away from the water pump 3, making it convenient for operators to adjust the inlet flow direction of the liquid according to the cleaning progress.

[0021] Specifically, the cleaning cylinder 1 is also equipped with a water inlet pipe 15 located below the filter screen 18. The water inlet pipe 15 is connected to the second three-way pipe 5 to form a closed cleaning fluid circulation system.

[0022] A lockable container 19 is slidably connected inside the cleaning cylinder 1. The container 19 is used to hold the plastic waste to be cleaned. A filter screen 18 is fixed to the bottom of the container 19 with bolts. The pore size of the filter screen 18 is carefully selected according to the particle size of the waste material, which can effectively intercept the waste material while allowing the cleaning fluid to pass through smoothly. A baffle 6 is fixed to the upper end of the container 19, which abuts against the upper end of the cleaning cylinder 1. The baffle 6 is used to limit the container 19 and prevent it from moving downward.

[0023] A limiting plate 7 is fixed to the bottom of the baffle 6, and a matching U-shaped block 8 is fixed to the outer wall of the cleaning cylinder 1. The limiting plate 7 is slidably connected inside the U-shaped block 8 and locked by bolts to ensure the stability of the container cylinder 19 during the cleaning process and the stability of the motor 9 during operation. When it is necessary to remove the container cylinder 19 for cleaning or replacement, simply loosen the bolts to easily lift the container cylinder 19.

[0024] Two connecting blocks 10 are fixed to the upper end of the baffle 6, and connecting holes are provided through the connecting blocks 10. This design allows the operator to use tools (such as hooks, ropes, etc.) to connect to the connecting blocks 10, thereby safely and efficiently lifting the container 19 upwards to separate it from the cleaning container 1, which facilitates subsequent cleaning and maintenance. After removal, tilting the container 19 can pour out the cleaned plastic particles.

[0025] In addition, a motor 9 is installed on the baffle 6. The motor 9 is a low-noise, high-torque model to meet the needs of long-term continuous operation. A drive shaft 17 is fixed to the output end of the motor 9, and multiple rod brushes 16 are fixed on the drive shaft 17. The rod brushes 16 are made of wear-resistant and corrosion-resistant materials, and their length and arrangement are optimized to brush the plastic waste in the container 19 from all directions without dead angles, effectively removing stains and impurities from the surface of the waste.

[0026] After cleaning, the container 19 is moved up out of the water surface, while the motor 9 continues to work, which can stir the plastic particles and drain them quickly.

[0027] First, based on the particle size of the plastic waste to be cleaned (which will subsequently form plastic granules), a filter screen 18 with an appropriate pore size is carefully selected and fixed to the bottom of the container 19. This step is crucial; a suitable filter screen pore size can effectively intercept the waste material, preventing it from flowing out with the cleaning fluid, while also ensuring the smooth passage of the cleaning fluid and maintaining its normal circulation.

[0028] Next, the plastic waste to be cleaned is placed into the container 19, and then the container 19 is slowly lowered into the cleaning tube 1. During the lowering process, ensure that the baffle 6 fixed at the upper end of the container 19 abuts against the upper end of the cleaning tube 1. The baffle 6 serves to limit the container 19 and prevent it from moving downwards during the cleaning process. At the same time, the limiting plate 7 fixed at the bottom of the baffle 6 is slidably connected to the matching U-shaped block 8 fixed on the outer wall of the cleaning tube 1 and locked with bolts. This ensures the stability of the container 19 during the cleaning process and provides a guarantee for the stable operation of the motor 9.

[0029] Turn on the water pump 3. At this time, the third control valve 13 and the first control valve 11 are in the open state. The pipe on the third control valve 13 is connected to the external cleaning fluid tank. In this way, the cleaning fluid can be transported to the cleaning cylinder 1 through the second three-way pipe 5 and the first three-way pipe 4. The cleaning fluid enters the holding cylinder 19 through the filter screen 18. After injecting the appropriate cleaning fluid, close the third control valve 13 and open the fourth control valve 14 to form a closed circulation system between the cleaning cylinder 1, the water pump 3 and the pipeline structure. That is, the cleaning fluid circulates in the cleaning cylinder 1 and the holding cylinder 19 and drives the plastic particles to move.

[0030] The motor 9, mounted on the baffle 6, is started. Motor 9 is a low-noise, high-torque model, capable of meeting the needs of long-term continuous operation. After motor 9 starts running, the drive shaft 17 fixed at its output end rotates, thereby driving multiple rod brushes 16 fixed on the drive shaft 17 to rotate. The rod brushes 16 are made of wear-resistant and corrosion-resistant materials, and their length and arrangement are optimized to ensure comprehensive and thorough cleaning of the plastic waste inside the container 19 during rotation.

[0031] Under the scrubbing action of the brush 16, combined with the circulating flow of the cleaning fluid, stains and impurities on the surface of the waste material are effectively removed. The cleaning fluid continuously washes over the waste material, carrying away the scrubbed stains and impurities, and filters them through the filter screen 18, keeping the cleaning fluid relatively clean and ensuring a continuous and effective cleaning effect. Throughout the cleaning process, the operator can optimize the cleaning effect by adjusting the flow rate and pressure of the water pump 3 and the speed of the motor 9, ensuring that the plastic waste is thoroughly and completely cleaned.

[0032] After cleaning is completed, turn off the water pump 3 and related control valves to stop the circulation of the cleaning fluid. Then loosen the bolts of the locking limit plate 7 and the U-shaped block 8. Using the two connecting blocks 10 fixed at the upper end of the baffle 6, which have through holes, the operator can use tools (such as hooks, ropes, etc.) to connect to the connecting blocks 10 and safely and efficiently lift the container 19 upwards to separate it from the cleaning container 1.

[0033] After the container 19 is lifted off the water surface, the motor 9 continues to operate. At this time, the rotation of the rod brush 16 agitates the washed plastic granules, causing them to tumble continuously within the container 19, thereby accelerating the drying speed of the surface water and improving the drainage efficiency.

[0034] Opening the second control valve 12 allows the cleaning fluid to be discharged, facilitating subsequent replacement of the cleaning fluid and cleaning of the inside of the cleaning cylinder 1.

[0035] Subsequently, clean water can be supplied to clean the washed plastic particles.

[0036] After the plastic granules have drained, turn off motor 9. Tilt the container 19 to pour out the washed and drained plastic granules, completing the washing process. Afterwards, the container 19 can be cleaned or the filter screen 18 can be replaced as needed for next use. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
