Description

Technical Field

[0001] The present invention relates to the technical field of plastic film processing, and in particular to a PET film plastic recycling and processing device. Background Art

[0002] After use, PET films have high recycling value. The common recycling method is to first crush, wash, and then melt and granulate. In the existing washing process, the crushed plastic film is poured into a washing pool, and the water flow is driven by a water surface stirring roller to make the plastic film surge, so as to achieve the cleaning effect. However, this method has obvious limitations. It is difficult to control the rotation speed of the stirring roller. If the rotation speed is too fast, the plastic film is easily thrown out of the pool, while if the rotation speed is too slow, it is difficult to ensure the cleaning effect. At the same time, simply relying on water flow stirring cannot fully knead the plastic film, resulting in stubborn stains remaining.

[0003] In addition, due to the low density of the plastic film, some film pieces will float on the water surface or be supported by the bottom film and cannot be completely immersed, reducing the cleaning efficiency. There are also some plastic films that will suspend in the middle of the water pool after absorbing water, resulting in the stirring roller being unable to contact the film pieces in this area, further affecting the cleaning effect.

[0023] It further includes a separation plate 103; a plurality of separation plates 103 are fixedly connected to the lower side of the guiding plate 5, and all the separation plates 103 are arranged at equal intervals from front to back; the lower side of each separation plate 103 does not contact the upper side of the layered plate 104.

[0024] The right side of the layered plate 104 is inclined upwards.

[0025] A plurality of rubber bumps are arranged on one side of each scrubbing plate 101 facing the baffle 102, which increases the friction between the scrubbing plate 101 and the plastic film and improves the cleaning ability of the equipment for the plastic film.

[0026] The left sides of all the separation plates 103 are set to be arc-shaped to prevent the plastic film from getting stuck and piling up.

[0027] After the recycled plastic film is crushed, the crushed plastic film needs to be poured into the cleaning pool 1. Then, the external pump is started, and through the circulating water pipe 3, clean water is poured into the cleaning pool 1. The plastic film is cleaned by the clean water in the cleaning pool 1. Subsequently, the plastic film is recycled through subsequent steps such as drying, melting, and granulation. During the cleaning process, since the plastic film is relatively light and usually floats on the water surface, the existing method uses the water surface stirring roller to stir the plastic film, making it move towards the filtration pool 2 along with the water flow. At the same time, under the action of the stirring roller, it tumbles and is cleaned in the water. Finally, the cleaned sewage and the plastic film flow towards the filtration pool 2 together. The filtered sewage returns to the cleaning pool 1 under the action of the circulating water pipe 3, and the plastic film is intercepted by the filtration pool 2 and transferred to the subsequent processing area through an external suction device.

[0028] When the crushed plastic film is poured into the cleaning pool 1, it is prone to piling up and floating, resulting in internal impurities being wrapped and difficult to sink. To solve this problem, a first air pipe 4 is set in the area where the plastic film is poured into the cleaning pool 1. When the plastic film enters the cleaning pool 1, the external air pumping device is started, and gas is conveyed into the pool through the first air pipe 4. The gas forms bubbles in the water, and during the upward floating process of the bubbles, the clean water is tumbling. The tumbling water flow prompts the plastic film to spread and separate from each other, thereby releasing the wrapped impurities. The heavier impurities sink to the bottom naturally after separation, achieving the preliminary cleaning of the plastic film and the separation of impurities.

[0029] After the plastic film is washed away by the water flow, when using the stirring roller on the water surface for cleaning, the rotation speed of the stirring roller needs to be precisely controlled: if the rotation speed is too fast, some plastic films will be thrown out of the cleaning pool 1; if the rotation speed is too slow, the cleaning effect will be poor. In addition, relying solely on the stirring roller to move the plastic film along with the water flow makes it difficult to fully rub the plastic films against each other, resulting in stubborn impurities on the surface not being completely removed. At the same time, some plastic films floating on the water surface are not fully immersed in the water, resulting in a poor cleaning effect. To solve this problem, when the water flow drives the plastic film past the left side of the guide plate 5, the plastic film floods into the lower side of the limiting part 5001 under the guidance of the guide plate 5. Since the limiting part 5001 is located in the water, the floating plastic film is forced to be immersed in the water under its restriction, ensuring that all plastic films are in full contact with the water. Subsequently, when the plastic film flows out from the right side of the limiting part 5001, the electric push rod 108 at the rear starts to reciprocate and stretch, driving the scrubbing plate 101 to approach and move away from the baffle plate 102, and at the same time making the first elastic member 107 continuously stretch and contract. Since the electric push rod 108 is inclined towards the right side of the cleaning pool 1, the scrubbing plate 101 also moves in an inclined manner and cooperates with the stationary baffle plate 102 to scrub the plastic film, effectively removing stubborn impurities on the surface, improving the cleaning effect, and preventing the plastic film from being thrown out of the pool. During this process, the rear flow channel 10101 is blocked due to the expansion of the first elastic member 107, and the plastic film flows towards the front flow channel 10101 under the inclined guiding action of the first elastic member 107. When the electric push rod 108 at the rear contracts, the electric push rod 108 at the front immediately extends, and the two work alternately to ensure that the plastic film is fully scrubbed while continuously flowing, achieving efficient cleaning without affecting normal flow.

[0030] It is also considered that all the separation plates 103 are arranged at equal intervals from front to back, so that the floating plastic films cannot accumulate with each other under the blockage of the separation plates 103, preventing the plastic films from entering the scrubbing area of the scrubbing plate 101 in a large - area agglomerated manner under the lower side of the guide plate 5, and enabling the plastic films to be scrubbed by the scrubbing plate 101 in a more dispersed state, improving the cleaning effect of the equipment on the plastic films.

[0031] It is also considered that when the electric push rod 108 pushes the scrubbing plate 101 close to the baffle plate 102 to scrub the plastic film, in order to reduce the water flow resistance during the movement of the scrubbing plate 101, and at the same time to reduce the water in the cleaning pool 1 pushed by the scrubbing plate 101 towards the baffle plate 102, resulting in the disorder and surging of the water flow direction, and thus preventing impurities from floating up again, the overall height of the scrubbing plate 101 is adjusted to as Figure 5As shown, the depth of immersion of the lower side of the washboard 101 is greater than the thickness of the floating and piled plastic film, ensuring that the washboard 101 can more effectively push the plastic film for scrubbing work. At the same time, it also reduces the resistance of the water flow to the washboard 101, avoiding the disorder and surging of the water flow direction. To ensure that all the plastic film floating in the cleaning tank 1 can be effectively scrubbed by the washboard 101, a layered plate 104 is provided in the middle of the cleaning tank 1. This structure first bears the plastic film floating in the middle through the horizontal section, preventing it from sinking too deep, and makes the plastic film move to the right under the drive of the water flow. When the plastic film reaches the right side of the layered plate 104, with the help of its upward-sloping design, under the combined action of the water flow power and the inclined plane guidance, the plastic film is lifted back to the upper area accessible by the washboard 101, thus ensuring that all the plastic film can be fully scrubbed and significantly improving the cleaning effect of the equipment.

[0032] It is also considered that although the layered plate 104 can effectively guide the plastic film to be lifted to the working area of the washboard 101, during the operation, it is found that the impurities settling naturally are easily piled up on the upper side of the layered plate 104 and flow to the washboard 101 along with the plastic film, resulting in the impurities being kneaded back into the plastic film. For this reason, a number of through holes are provided on the layered plate 104 to achieve separation by using the size difference between the plastic film and the impurities. When the impurities pass through the upper side of the layered plate 104 along with the water flow, the smaller impurities will fall from the through holes, while the larger-sized plastic film can smoothly pass above the through holes and flow to the circulation groove 10101. In addition, the upward-sloping structure on the right side of the layered plate 104 can form a secondary interception of the impurities. Since the acting force of the water flow on the impurities is weak, it is more difficult for the impurities to cross the inclined section and enter the circulation groove 10101, thus significantly improving the impurity separation efficiency of the equipment.

[0033] When the water flow drives the plastic film to move on the upper side of the layered plate 104, although the through holes can separate the impurities, they may hinder the flow of the plastic film. Therefore, when the electric push rod 108 extends, it will stretch the airbag 201 to reduce the internal air pressure. At this time, the external air pressure will push open the one-way valve diaphragm at the second air pipe 202 for air supplement. When the electric push rod 108 contracts, it compresses the airbag 201 and presses the gas into the air groove 20401 of the air collection box 204 through the third air pipe 203. As the air pressure continues to rise, the gas will push open the baffle 205 and stretch the second elastic member 206, so that the air blowing hole of the air collection box 204 is opened, and the gas sprays onto the upper side of the layered plate 104, pushing the plastic film to move smoothly to the right, effectively preventing accumulation. When the air pressure is insufficient, the second elastic member 206 drives the baffle 205 to reset, and uses its diameter larger than the air blowing hole to achieve sealing, reliably preventing the water in the cleaning tank 1 from flowing back into the airbag 201.

[0034] Embodiment 2 On the basis of Embodiment 1, as Figure 1 、 Figure 9 and Figure 10As shown, it further includes a first partition plate 105; the first partition plate 105 is fixedly connected to the inside of the cleaning tank 1; each first air pipe 4 penetrates through the first partition plate 105; the first partition plate 105 divides the cleaning tank 1 into upper and lower regions, a first rectangular cavity 1001 above the first partition plate 105 and a second rectangular cavity 1002 below the first partition plate 105; two communication grooves 10501 are formed on the first partition plate 105; the first rectangular cavity 1001 and the second rectangular cavity 1002 are communicated through the communication grooves 10501.

[0035] It further includes a second partition plate 106; two second partition plates 106 are fixedly connected to the lower side of the first partition plate 105; the two second partition plates 106 are arranged in a vertically staggered manner.

[0036] The middle part of the first partition plate 105 is V-shaped.

[0037] During the operation of the equipment, as impurities at the bottom of the cleaning tank 1 continuously accumulate, when the impurities accumulate too high, they may float up again due to the water surface surging or water flow disturbance and adhere to the surface of the plastic film, affecting the cleaning effect. To solve this problem, a first partition plate 105 is provided in the cleaning tank 1, so that the deposited impurities are concentrated on the upper surface of the first partition plate 105. Subsequently, the impurities flow from the first rectangular cavity 1001 to the second rectangular cavity 1002 along the communication grooves 10501. The first air pipe 4 generates bubbles above the first partition plate 105, while the liquid surging degree in the second rectangular cavity 1002 is lower due to the weakened effect of the bubbles, thus effectively preventing the impurities from floating up again through the communication grooves 10501 and adhering to the plastic film, significantly improving the impurity collection ability of the equipment. In addition, the first partition plate 105 adopts a V-shaped structure design, and the V-shaped depression in the middle can accelerate the sliding of impurities towards the communication grooves 10501, further optimizing the impurity separation efficiency and ensuring a more stable and reliable cleaning process. To further prevent the deposited impurities from floating up, two second partition plates 106 are added to the lower side of the first partition plate 105. The two second partition plates 106 are arranged in a vertically staggered manner to form a tortuous flow path. This structure can effectively inhibit the upward floating of impurities, thus ensuring that the impurities are stably collected in the second rectangular cavity 1002 and improving the overall impurity separation effect.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
