Description

Technical Field

[0001] This utility model relates to the field of waste plastic film recycling technology, specifically to a waste plastic film crushing and washing system. Background Technology

[0002] Mulching technology has become an important means to ensure water conservation, stable yields, and high yields in agriculture, playing a significant role in increasing farmers' income, agricultural production, and adjusting the agricultural planting structure. However, since existing mulch films are primarily made of PE plastic, which is not easily degraded, their residue in the soil causes white pollution. Therefore, it is necessary to recycle and dispose of waste mulch films.

[0003] After recycling, waste plastic film needs to be shredded into sheets from its clumps, and then washed to remove impurities, resulting in clean film sheets for subsequent processing and utilization. Traditionally, manual collection and transfer are used between the shredding and washing equipment, which is inefficient. Current methods use a conveyor system in series between the two systems, but because the plastic film sheets are lightweight and difficult to collect, the conveyor system is unstable. Therefore, personnel are needed at both the input and output ends of the conveyor to collect the film sheets. Furthermore, the film sheets easily drift off and fall outside the conveyor during transport, requiring manual cleaning. Therefore, the current method also wastes manpower and time. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a waste plastic film crushing and washing system, which improves the conveying efficiency of plastic film sheets, is easy to use, and saves manpower and time.

[0005] This utility model is achieved through the following technical solution: a waste plastic film crushing and washing system, including a crusher and a washing machine, and a material blower. The inlet of the material blower is connected to the outlet of the crusher through a horizontal first air duct, and the outlet of the material blower is connected to a vertical second air duct. The upper end of the second air duct is connected to a horizontal third air duct through a 90° elbow, and the third air duct is connected to a vertical fourth air duct through a 90° elbow. The lower end of the fourth air duct is connected to the inlet of the washing machine.

[0006] In this design, the airflow provided by the material blower extracts the pulverized plastic film from the crusher and blows it along the second, third, and fourth air ducts into the washing machine for washing. The horizontal first air duct is better suited to the inlet of the material blower and the outlet of the crusher, facilitating communication between them. The second, third, and fourth air ducts are connected in series to form a U-shaped pipeline via two 90° elbows, which is also better suited to the outlet of the material blower and the inlet of the washing machine, facilitating communication between them.

[0007] Through the air delivery method of the material blower, the light plastic film can be smoothly and quickly blown, with higher conveying efficiency, more suitable for the conveying of light plastic film, and the conveying process is more stable. And the whole conveying process is in a closed state, thus avoiding the plastic film from falling outside, and no personnel assistance is required, saving manpower and working hours, and being more convenient to use.

[0008] As an optimization, the bottom of the material blower is fixedly connected with a chassis, and the chassis is fixed to the ground by bolts. This optimization scheme fixes the material blower to the ground through the chassis, improving the stability of the material blower.

[0009] As an optimization, the chassis is in a "day" - shaped structure. This optimization scheme increases the support area of the chassis, thereby further improving the support stability for the material blower.

[0010] As an optimization, a rubber cushion plate is fixedly connected to the bottom of the chassis. This optimization scheme weakens the vibration and improves the shock absorption effect by setting a rubber cushion plate at the bottom of the chassis, thereby improving the stability.

[0011] As an optimization, a first pipeline expansion joint is connected between the first air duct and the discharge port of the crusher. This optimization scheme reduces the vibration transmission through the expansion of the first pipeline expansion joint, preventing the vibration of the material blower from being transmitted to the crusher and causing damage to the pipeline interface, thereby improving the system stability.

[0012] As an optimization, a second pipeline expansion joint is connected between the lower end of the fourth air duct and the feed inlet of the scrubber. This optimization scheme reduces the vibration transmission through the expansion of the second pipeline expansion joint, preventing the vibration of the material blower from being transmitted to the scrubber and causing damage to the pipeline interface, thereby further improving the system stability.

[0013] As an optimization, the output port of the material blower is inclined upward at 45°, and the output port of the material blower is connected to the lower end of the second air duct through a 45° elbow. In this optimization scheme, the output port of the material blower is inclined at 45°, reducing the resistance and making the air flow more smooth upward, so that the feeding of the plastic film is more smooth.

[0014] As an optimization, a vertical support rod is fixedly connected to the bottom of the third air duct, and the lower end of the support rod is fixedly connected to the ground. This optimization scheme supports the third air duct through the support rod, improving the stability of the third air duct.

[0015] The beneficial effects of this invention are as follows: The lightweight mulch film can be smoothly and quickly conveyed via a material blower, resulting in higher conveying efficiency, making it more suitable for conveying lightweight mulch film, and ensuring a more stable conveying process. Furthermore, the entire conveying process is enclosed, preventing the mulch film from falling to the outside and eliminating the need for manual assistance, thus saving manpower and time, and making it more convenient to use.

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] like Figures 1-4 As shown, a waste plastic film crushing and washing system includes a crusher 1 and a washing machine 2, as well as a material blower 3. The inlet of the material blower 3 is connected to the outlet of the crusher 1 via a horizontal first air duct 4, and the outlet of the material blower 3 is connected to a vertical second air duct 7. The upper end of the second air duct 7 is connected to a horizontal third air duct 9 via a 90° elbow 11, and the third air duct 9 is connected to a vertical fourth air duct 11 via a 90° elbow 210. The lower end of the fourth air duct 11 is connected to the inlet of the washing machine 2.

[0024] Specifically, the crusher 1, washing machine 2, and material blower 3 described in this embodiment are all existing equipment. The crusher 1 is a multi-functional plastic crusher based on our company's published patent CN113752428A. The washing machine 2 can be a waste plastic film washing device based on our company's prior patent application 2025210373115. The material blower 3 is an MQS5-54 material conveying blower, which can be directly purchased.

[0025] The bottom of the material blower 3 is fixedly connected to the chassis 13. The chassis 13 is in a "day" - shaped structure. A rubber cushion plate 14 is fixedly connected to the bottom of the chassis 13, and the chassis 13 is fixed to the ground by bolts. The bolts are anchor bolts, and the anchor bolts pass through the rubber cushion plate and the chassis in sequence and are screwed and fixed.

[0026] The material blower 3 is fixed to the ground through the chassis 13, improving the stability of the material blower 3. By setting the rubber cushion plate 14 at the bottom of the chassis 13, the vibration is weakened and the shock - absorption effect is improved, thereby further improving the stability.

[0027] Specifically, a first pipeline expansion joint 5 is connected between the first air duct 4 and the discharge port of the pulverizer 1. One end of the first air duct 4 is fixedly connected to the input port of the material blower 3, the other end of the first air duct 4 is fixedly connected to one end of the first pipeline expansion joint 5, and the other end of the first pipeline expansion joint 5 is fixedly connected to the discharge port of the pulverizer 1. The expansion and contraction of the first pipeline expansion joint 5 reduces the vibration transmission, preventing the vibration of the material blower 3 from being transmitted to the pulverizer 1 and causing damage to the pipeline interface, thus improving the system stability.

[0028] The output port of the material blower 3 in this embodiment is inclined upward at 45°. The output port of the material blower 3 is connected to the lower end of the second air duct 7 through a 45° elbow 6. One end of the 45° elbow 6 is fixedly connected to the output port of the material blower 3, and the other end of the 45° elbow 6 is fixedly connected to the lower end of the second air duct 7. The output port of the material blower 3 is inclined at 45°, reducing the resistance and making the air flow more smoothly upward, so that the delivery of the plastic film pieces is more smooth.

[0029] The upper end of the second air duct 7 is fixedly connected to one end of the first 90° elbow 8. The other end of the first 90° elbow 8 is fixedly connected to one end of the third air duct 9. The other end of the third air duct 9 is fixedly connected to one end of the second 90° elbow 10. The other end of the second 90° elbow 10 is fixedly connected to the upper end of the fourth air duct 11. The second air duct 7, the first 90° elbow 8, the third air duct 9, the second 90° elbow 10, and the fourth air duct 11 form a U - shaped pipeline, facilitating the connection between the output port of the material blower 3 and the feed port of the scrubbing machine 2.

[0030] Specifically, a second pipeline expansion joint 12 is connected between the lower end of the fourth air duct 11 and the feed port of the scrubbing machine 2. The lower end of the fourth air duct 11 is fixedly connected to the upper end of the second pipeline expansion joint 12, and the lower end of the second pipeline expansion joint 12 is fixedly connected to the feed port of the scrubbing machine 2. The expansion and contraction of the second pipeline expansion joint 12 reduces the vibration transmission, preventing the vibration of the material blower 3 from being transmitted to the scrubbing machine 2 and causing damage to the pipeline interface, thus further improving the system stability.

[0031] In this embodiment, both the first pipe expansion joint 5 and the second pipe expansion joint 12 are made of stainless steel and can be directly purchased.

[0032] Preferably, a vertical support rod 15 is fixedly connected to the bottom of the third air duct 9, and the lower end of the support rod 15 is fixed to the ground. The support rod 15 supports the third air duct 9 from below, improving the stability of the third air duct.

[0033] Working Principle: The airflow provided by the material blower 3 draws the pulverized mulch film from the discharge port through the crusher 1, and then blows the film along the second air duct 7, the third air duct 9, and the fourth air duct 11 into the washing machine 2 for washing. The airflow provided by the material blower 3 allows the lightweight mulch film to be smoothly and quickly conveyed, resulting in higher conveying efficiency and making it more suitable for conveying lightweight mulch film. The conveying process is also more stable. Furthermore, the entire conveying process is in a closed state, preventing the mulch film from falling to the outside and eliminating the need for personnel assistance, saving manpower and time, and making it more convenient to use.
