Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, and discloses a plastic particle pretreatment device. Background Art

[0002] Plastic particles refer to granular plastics, generally divided into more than 200 kinds, and subdivided into thousands of kinds. Common plastic particles include general plastics, engineering plastics, and special plastics. General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate, silicone, etc. Recycled plastic particles can be used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products. In the clothing industry, they can be used to manufacture clothing, ties, buttons, and zippers. In the building materials field, the derivative of recycled plastic particles, wood-plastic profiles, can be used to manufacture various building components, plastic doors and windows, etc. During the production process of plastics, the quality of plastic particles will have a certain impact on the produced finished products. During the production process of plastic particles, they are often contaminated with sundries and dust, resulting in low cleanliness of plastic particles and affecting the quality of plastic particles. Therefore, plastic particles are often cleaned before plastic production to ensure the quality of plastic particles. Hence, a plastic particle pretreatment device for plastic production is needed.

[0003] However, the patents in the prior art have the following several disadvantages:

[0004] (1) During cleaning, a large amount of plastic particles accumulate, making it difficult to clean the plastic particles and unable to completely clean a large amount of plastic particles.

[0005] (2) After cleaning, the water on the surface of the plastic particles cannot be removed. Content of the Utility Model

There are fans 201 on both the left and right sides of the upper surface of the dehydration tank 2. The fans 201 can blow air into the dehydration tank 2 to dry the moisture on the surface of the plastic particles. There is a drain pipe 202 at the left end of the bottom of the dehydration tank 2, which is used to discharge the cleaning liquid at the bottom of the dehydration tank 2. There is an installation frame 3 inside the dehydration tank 2. There is an opening on the bottom surface of the installation frame 3. There are grooves 301 on both the left and right end surfaces inside the installation frame 3. There are extension plates 305 at both ends of the installation frame 3. There are push plates 306 at the mutually remote ends of the two extension plates 305. A collection box 4 is movably connected inside the installation frame 3, which is used to collect plastic particles. There are sliders 403 at both the left and right ends of the collection box 4. The sliders 403 are slidably connected to the grooves 301. The sliders 403 can ensure that the collection box 4 moves up and down following the installation frame 3. There is a handle 401 at the front end of the collection box 4, which is convenient for pulling the collection box 4. There is a filter screen 402 at the bottom end inside the collection box 4, which can allow the cleaning liquid to pass through.

[0033] Specifically, the stirring assembly 6 includes a second motor 601. The second motor 601 is fixedly connected to the upper end of the cleaning tank 1. The bottom end of the second motor 601 is connected to a rotating shaft 602. The second motor 601 can control the rotation of the rotating shaft 602. There are stirring plates 603 on the surface of the rotating shaft 602. There are a number of uniformly distributed through holes 604 on the surface of the stirring plates 603, which can allow water to pass through and reduce the resistance of the rotation of the stirring plates 603.

[0034] Through the above technical solution, the second motor 601 can drive the stirring plates 603 to rotate through the rotating shaft 602, stir the plastic particles in the cleaning tank 1, so that they can fully contact with the cleaning liquid and improve the cleaning effect.

[0035] Specifically, there are slots 302 on both the left and right sides of the upper surface of the installation frame 3. There are magnet plates 303 at the bottom ends inside the slots 302. A blocking rod 304 is slidably connected between the two slots 302. The blocking rod 304 is made of iron and can be attracted by the magnet plates 303.

[0036] Through the above technical solution, the shift lever 304 can block the collection box 4 to prevent it from sliding out from the front end of the mounting frame 3. Lifting the shift lever 304 upward can remove it to facilitate taking out the collection box 4.

[0037] Specifically, there are sliding grooves 203 on the left and right end surfaces of the dehydration tank 2. There are guide posts 204 inside the sliding grooves 203. The upper and lower ends of the guide posts 204 are fixedly connected to the dehydration tank 2. The extension plate 305 penetrates through the sliding grooves 203.

There are first motors 5 at both the left and right ends of the dehydration tank 2. Eccentric wheels 501 are connected to the mutually remote ends of the two first motors 5. The first motors 5 can drive the eccentric wheels 501 to rotate. The eccentric wheels 501 contact the push plates 306. There is a spring 205 at the upper end of the extension plate 305. The spring 205 is sleeved on the guide posts 204. The spring 205 can push the extension plate 305 downward.

[0038] Through the above technical solution, the first motor 5 drives the eccentric wheel 501 to rotate. When the convex part of the eccentric wheel 501 contacts the push plate 306, it can jack it up, and then jack up the collection box 4. When the convex part of the eccentric wheel 501 rotates downward, the spring 205 will use its elastic force to push the extension plate 305 downward, and then make the collection box 4 move downward. Repeating this way, the collection box 4 vibrates up and down continuously, making the plastic particles tumble, increasing the contact area with the wind, and improving the dehydration rate.

[0039] During use, pour the cleaning liquid and plastic particles into the cleaning tank 1 through the feed hopper 101. Then start the second motor 601. The second motor 601 can drive the stirring plate 603 to rotate through the rotating shaft 602, stirring the plastic particles in the cleaning tank 1 so that they can fully contact the cleaning liquid and improve the cleaning effect. After cleaning, open the valve 103. The cleaning liquid and plastic particles fall into the collection box 4 through the discharge pipe 102. The cleaning liquid will pass through the filter screen 402 and finally be discharged through the drain pipe 202. The fan 201 can continuously blow air into the collection box 4 to air-dry the moisture on the surface of the plastic particles. At the same time, the first motor 5 drives the eccentric wheel 501 to rotate. When the convex part of the eccentric wheel 501 contacts the push plate 306, it can jack it up, and then jack up the collection box 4. When the convex part of the eccentric wheel 501 rotates downward, the spring 205 will use its elastic force to push the extension plate 305 downward, and then make the collection box 4 move downward. Repeating this way, the collection box 4 vibrates up and down continuously, making the plastic particles tumble, increasing the contact area with the wind, and improving the dehydration rate. After dehydration, lift the shift lever 304 upward and pull the handle 401 to take out the collection box 4 to facilitate the recycling of the plastic particles.
