Description

Technical Field

[0001] This utility model belongs to the field of waste plastic technology, and specifically relates to a waste plastic anti-fouling and high-efficiency recycling and treatment equipment. Background Technology

[0002] Waste plastics come from a wide range of sources and are already heavily contaminated with dirt and grime during the disposal stage. This includes food residue and oil stains from household waste plastics, chemical residues from industrial waste plastics, and soil trapped in agricultural plastic films. This contamination severely impacts subsequent recycling processes, reducing the purity and quality of the recycled plastics and significantly diminishing the performance of the resulting recycled plastic products.

[0003] When cleaning waste plastics, cleaning agents are typically introduced into water to remove oil, mud, dust, and other contaminants from the plastic surface. Since the containers holding the cleaning solution are mostly static, the water remains stationary. This means the cleaning agent can only slowly diffuse and mix with the water. Firstly, this mixing method is extremely inefficient, time-consuming, and severely slows down the entire recycling process, reducing production efficiency. Secondly, uneven mixing results in inconsistent cleaning concentrations, with some areas having excessively high concentrations and others too low, leading to inconsistent cleaning results. This results in varying levels of residue on the surface of the recycled plastic after cleaning. After cleaning, the plastic surface retains a large amount of moisture, and waiting for it to air dry takes considerable time, further impacting work efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a waste plastic anti-fouling and high-efficiency recycling and treatment device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-efficiency, anti-fouling recycling and processing device for waste plastics, comprising a cleaning tank, an insertion pipe installed at one end of the cleaning tank, a cleaning assembly rotatably mounted on the insertion pipe and located within the inner cavity of the cleaning tank, the cleaning assembly being inclined, and symmetrically engaged with stirring mechanisms on the cleaning assembly, a drive motor fixedly mounted on one of the two stirring mechanisms, the drive motor being fixed to the cleaning tank, a water outlet tank connected to one end of the cleaning tank, a water-spinning assembly rotatably mounted inside the water outlet tank, a power assembly engaged at one end of the water-spinning assembly, the power assembly being mounted on the water outlet tank.

[0008] Furthermore, the bottom four corners of the cleaning box are fixedly installed with support legs, the two ends of the cleaning box are symmetrically connected with drain outlets, and the top of the cleaning box is connected with a feed inlet.

[0009] Furthermore, the cleaning assembly includes a cleaning cylinder, which is inclined, with one end of the cleaning cylinder rotatably mounted on the insertion tube and the other end rotatably mounted on the cleaning box, and the cleaning cylinder having multiple round holes.

[0010] Furthermore, a screw conveyor blade is fixedly installed on the inner wall of the cleaning cylinder, and a rotating gear is fixedly installed at one end of the cleaning cylinder.

[0011] Furthermore, both of the stirring mechanisms include a rotating shaft, both of the rotating shafts are rotatably mounted on the cleaning tank, both of the rotating shafts are fixedly mounted on their outer walls, both of the fixed gears mesh with the rotating gears, and multiple stirring blades are linearly arrayed on the outer walls of the two rotating shafts, with the output end of the drive motor located on one of the two rotating shafts.

[0012] Furthermore, the bottom of the water outlet bucket is connected to a water outlet, the water-spinning assembly includes a water-spinning bucket, the water-spinning bucket is rotatably mounted on the water outlet bucket and located on one side of the cleaning cylinder, the water-spinning bucket has multiple water-spinning holes, and a connecting gear is fixedly installed at one end of the water-spinning bucket.

[0013] Furthermore, the power assembly includes a power motor, which is fixedly mounted on the water outlet tank. A power shaft is fixedly mounted on the output end of the power motor, and a power gear is fixedly mounted on the other end of the power shaft. The power gear meshes with the connecting gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. The rotational power of the drive motor in this invention is directly transmitted to the connected stirring mechanism, causing it to start rotating. The two stirring mechanisms rotate synchronously by meshing with the cleaning component. Therefore, when the stirring mechanism connected to the drive motor rotates, the inclined cleaning component will also rotate on the inlet tube and inside the cleaning tank. When the waste plastic enters the inlet tube, it then enters the cleaning component. At this time, the joint rotation of the cleaning component and the stirring mechanism agitates the water in the cleaning tank, accelerating the mixing speed of the cleaning agent and water. This changes the problem of slow natural diffusion and fusion of the cleaning agent in traditional static containers, ensuring uniform concentration of the cleaning solution and improving the cleaning effect. On the other hand, the rotating cleaning component can directly act on the waste plastic, removing dirt from the plastic surface through friction, tumbling, etc., such as food residue and oil stains on household waste plastics, chemical reagent residues carried by industrial waste plastics, and soil wrapped in agricultural plastic film, effectively improving the cleaning quality of waste plastics.

[0016] 2. When the power component of this utility model is started, since it is installed on the water outlet tank and meshes with one end of the water-spinning component, the rotational motion of the power component is transmitted to the water-spinning component, causing it to rotate inside the water outlet tank. The high-speed rotating water-spinning component uses centrifugal force to throw off a large amount of water adhering to the plastic surface. Compared with the traditional method of waiting for natural drying, which takes a lot of time, this water-spinning method can quickly remove water, greatly improve work efficiency, and avoid the re-contamination of plastics by bacteria and mold due to water residue. At the same time, it shortens the subsequent processing cycle and provides a strong guarantee for the efficient recycling process of waste plastics. The water that is thrown off falls back onto the inner wall of the water outlet tank and is then discharged from the water outlet tank. The entire equipment achieves seamless connection from cleaning to water-spinning, ensuring the high efficiency and high quality of waste plastic recycling in all aspects.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6As shown, this utility model is a waste plastic anti-fouling and high-efficiency recycling and treatment device, including a cleaning tank 1. One end of the cleaning tank 1 is equipped with an inlet pipe 2. A cleaning component 3 is rotatably installed on the inlet pipe 2 and located in the inner cavity of the cleaning tank 1. The cleaning component 3 is inclined. A stirring mechanism 4 is symmetrically engaged on the cleaning component 3. A drive motor 5 is fixedly installed on one of the two stirring mechanisms 4. The drive motor 5 is fixed on the cleaning tank 1. One end of the cleaning tank 1 is connected to a water outlet tank 6. A water-spraying component 7 is rotatably installed inside the water outlet tank 6. A power component 8 is engaged at one end of the water-spraying component 7. The power component 8 is installed on the water outlet tank 6.

[0030] The cleaning tank 1 contains water and cleaning agent, which activates the drive motor 5. Since the drive motor 5 is fixed to the cleaning tank 1 and connected to one of the stirring mechanisms 4, the rotational power of the drive motor 5 is directly transmitted to the connected stirring mechanism 4, causing it to start rotating. The two stirring mechanisms 4 rotate synchronously by meshing with the cleaning assembly 3. Therefore, when the stirring mechanism 4 connected to the drive motor 5 rotates, the tilted cleaning assembly 3 will also rotate on the inlet pipe 2 and inside the cleaning tank 1. When the waste plastic enters the inlet pipe 2, it subsequently enters the cleaning assembly 3. At this time, the joint rotation of the cleaning assembly 3 and the stirring mechanism 4 agitates the originally still water in the cleaning tank 1, accelerating the mixing speed of the cleaning agent and water. This overcomes the problem of slow natural diffusion and fusion of the cleaning agent in traditional static containers, ensuring uniform concentration of the cleaning solution and improving the cleaning effect. Furthermore, the rotating cleaning assembly 3 can directly act on the waste plastic, removing dirt from the plastic surface through friction and tumbling, such as food residue and oil stains on household waste plastics, and chemical residues carried by industrial waste plastics. Reagent residues and soil trapped in agricultural plastic film are effectively removed, significantly improving the cleaning quality of waste plastics. As the cleaning component 3 rotates, the waste plastics are slowly pushed into the spin-dry component 7. Once the cleaned waste plastics enter the spin-dry component 7 from the cleaning tank 1, the power component 8 is activated. Since it is installed on the outlet tank 6 and meshes with one end of the spin-dry component 7, the rotational motion of the power component 8 is transmitted to the spin-dry component 7, causing it to rotate within the outlet tank 6. The high-speed rotating spin-dry component 7 uses centrifugal force to remove a large amount of water adhering to the surface of the plastic. Compared to the traditional method of waiting for natural drying, which takes a lot of time, this spin-drying method can quickly remove water, greatly improving work efficiency and preventing bacteria and mold from re-contaminating the plastics due to residual water. It also shortens the subsequent processing cycle, providing a strong guarantee for the efficient recycling process of waste plastics. The water that is spin-dryed falls back onto the inner wall of the outlet tank 6 and is then discharged from the outlet tank 6. The entire equipment achieves seamless connection from cleaning to spin-drying, comprehensively ensuring the high efficiency and high quality of waste plastic recycling.

[0031] In one embodiment, for the cleaning tank 1, support legs 101 are fixedly installed at the four corners of the bottom of the cleaning tank 1, drain outlets 102 are symmetrically connected to both ends of the cleaning tank 1, and feed inlet 103 is connected to the top of the cleaning tank 1.

[0032] The four support legs 101 at the bottom corners of the cleaning tank 1 play a crucial supporting role. They stably raise the cleaning tank 1 a certain height off the ground or operating platform. Through the feed inlet 103 at the top, operators can easily add water and cleaning agent into the cleaning tank 1. In the initial stage of waste plastic recycling, water is first injected into the cleaning tank 1 through the feed inlet 103 in a certain proportion, followed by an appropriate amount of cleaning agent. The drain outlets 102, which are symmetrically connected at both ends of the cleaning tank 1, are used to discharge the wastewater after cleaning. After the cleaning process is completed, the valve on the drain outlet 102 is opened (the valve is not shown in the diagram; the valve controls the opening or closing of the drain outlet 102), and the wastewater flows out from the drain outlet 102 under the action of gravity.

[0033] In one embodiment, the cleaning assembly 3 includes a cleaning cylinder 301, which is inclined. One end of the cleaning cylinder 301 is rotatably mounted on the insertion tube 2, and the other end is rotatably mounted on the cleaning box 1. The cleaning cylinder 301 has a plurality of round holes 302.

[0034] The inner wall of the cleaning cylinder 301 is fixedly installed with an auger spiral blade 303, and a rotating gear 304 is fixedly installed at one end of the cleaning cylinder 301.

[0035] Both of the stirring mechanisms 4 include a rotating shaft 401, both of the rotating shafts 401 are rotatably mounted on the cleaning tank 1, both of the rotating shafts 401 are fixedly mounted on the outer wall of the two rotating shafts 401, both of the fixed gears 402 mesh with the rotating gear 304, and multiple stirring blades 403 are linearly arranged on the outer wall of the two rotating shafts 401. The output end of the drive motor 5 is on one of the two rotating shafts 401.

[0036] When cleaning waste plastics begins, an appropriate amount of water and cleaning agent is first added into the cleaning tank 1 through the feed inlet 103 at the top to prepare for the cleaning operation. Then, the drive motor 5 is started, and its output drives a connected rotating shaft 401 to rotate. Since the fixed gears 402 on both rotating shafts 401 mesh with the rotating gear 304 at one end of the cleaning cylinder 301, when the rotating shaft 401 driven by the drive motor 5 rotates, the other rotating shaft 401 will rotate synchronously through the rotating gear 304 via gear transmission. Multiple linearly arrayed stirring blades 403 on the outer walls of the two rotating shafts 401 agitate the cleaning liquid and water in the cleaning tank 1 at high speed as the rotating shafts 401 rotate. This allows the cleaning agent to mix with water quickly and evenly, solving the problems of slow diffusion and uneven concentration of the cleaning agent in traditional static cleaning, and ensuring the efficient use of the cleaning solution. At the same time, with the support of the two ends of the cleaning cylinder 301 by the inlet tube 2 and the cleaning tank 1, the rotating gear 304 is driven by the fixed gear 402 connected to the drive motor 5 to rotate. In the inclined cleaning cylinder 301, after the waste plastic enters from the inlet tube 2, the auger blades 303 fixedly installed on its inner wall play a role. As the cleaning cylinder 301 rotates, the auger blades 303 will push the waste plastic to move slowly along the inclined direction of the cleaning cylinder 301, avoiding the accumulation of plastic in the cylinder and ensuring that each plastic part can be thoroughly cleaned. Furthermore, the plastic tumbles continuously inside the drum, ensuring that all parts of the plastic surface come into contact with the cleaning fluid. In addition, the cleaning drum 301 has multiple round holes 302. During the rotation of the cleaning drum 301, the cleaning fluid inside the tank can enter the cleaning drum 301 through the round holes 302, making full contact with the waste plastic and ensuring thorough cleaning. The dirt washed off the waste plastic can also be discharged into the main body of the cleaning tank 1 through the round holes 302, preventing dirt from accumulating inside the cleaning drum 301 and maintaining a good cleaning environment inside the drum.

[0037] In one embodiment, for the water outlet 6, the bottom of the water outlet 6 is connected to a water outlet 601, the water-spinning assembly 7 includes a water-spinning bucket 701, the water-spinning bucket 701 is rotatably mounted on the water outlet 6 and located on one side of the cleaning cylinder 301, the water-spinning bucket 701 is provided with a plurality of water-spinning holes, and a connecting gear 702 is fixedly mounted on one end of the water-spinning bucket 701.

[0038] The power assembly 8 includes a power motor 801, which is fixedly installed on the water outlet tank 6. A power shaft 802 is fixedly installed at the output end of the power motor 801, and a power gear 803 is fixedly installed at the other end of the power shaft 802. The power gear 803 meshes with the connecting gear 702.

[0039] After the waste plastic in the washing tank 1 has completed the washing process, it is necessary to quickly remove the large amount of residual water on the surface of the plastic. At this time, the water outlet tank 6 and its internal components begin to function. First, the washed waste plastic is transferred from one side of the washing drum 301 to the spin-off tank 701 by the auger spiral blades 303. Then, the power motor 801 is started. Since the power motor 801 is fixedly installed on the water outlet tank 6, its output end drives the power shaft 802 to rotate, which in turn causes the power gear 803 at the other end of the power shaft 802 to rotate synchronously. And because the power gear 803 and the spin-off tank 701 are connected, the water outlet tank 6 is also connected to the water outlet tank 701. The connecting gears 702 at one end mesh with each other, so under the action of gear transmission, the water-spinning bucket 701 starts to rotate at high speed on the water outlet bucket 6. The water-spinning bucket 701 is provided with multiple water-spinning holes. During the high-speed rotation, the waste plastic adheres tightly to the inner wall of the water-spinning bucket 701 due to centrifugal force and rotates at high speed along with the water-spinning bucket 701. At this time, the water on the surface of the plastic is driven by centrifugal force and is thrown out of the water-spinning bucket 701 through the water-spinning holes and falls into the inner wall of the water outlet bucket 6. The water outlet 601 is connected to the bottom of the water outlet bucket 6, and then the water in the water outlet bucket 6 is discharged from the water outlet 601.
