Description

Technical Field

[0001] This utility model relates to the technical field of plastic recycling equipment, and more specifically, to an ABS plastic recycling device. Background Technology

[0002] ABS plastic (acrylonitrile-butadiene-styrene copolymer) is widely used in electronic and electrical housings, automotive parts, and other fields due to its excellent impact resistance, corrosion resistance, and processing properties. With the continuous increase in the total amount of plastic waste, the recycling of ABS plastic has become a crucial link in resource recycling. In the ABS recycling process, the recycled damaged plastic needs to undergo pretreatment such as washing, screening, and wastewater impurity separation to remove surface stains, sort plastic particles of different sizes, and separate sediments, floating matter, and other impurities from the wastewater, providing clean raw materials for subsequent recycling and granulation.

[0003] Existing ABS recycling pretreatment devices generally have the following shortcomings: First, the cleaning and screening processes are often set up independently, resulting in large equipment space occupation and low processing efficiency; Second, traditional filter structures are mostly single-layer designs, making it difficult to accurately sort plastic particles of different sizes; Third, floating matter in wastewater (such as microplastics and light impurities) easily adheres to the filter screen surface, causing blockage, affecting the wastewater filtration effect, requiring frequent manual cleaning, and increasing operation and maintenance costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5As shown, the tank structure 1 includes a first side plate 101, a second side plate 102, a discharge port 103, a limiting block 104, and a feed port 105. The first side plate 101 is symmetrically provided with the second side plate 102. The first side plate 101 and the second side plate 102 are respectively provided with discharge ports 103. The inner sides of the first side plate 101 and the second side plate 102 are both fixedly provided with limiting blocks 104. The top of the second side plate 102 is provided with a feed port 105. A connecting plate is provided between the first side plate 101 and the second side plate 102. The first side plate 101, the second side plate 102, and the connecting plate together form a cleaning tank. The first side plate 101, the second side plate 102, and the connecting plate form the main body of the cleaning tank. The feed port 105 at the top of the second side plate 102 is used to introduce recycled and crushed ABS plastic. The limiting block 104 on the inner side of the first side plate 101 and the second side plate 102 is used to fix the drive shaft 303 of the filter structure 3. The discharge ports 103 on both sides correspond to the discharge channels of plastics with different particle sizes. The whole provides physical space support for spray cleaning, filtration and screening operations.

[0027] like Figure 1-5 As shown, the spray structure 2 includes a spray chamber 201, spray heads 202, a connection port 203, and a support rod 204. Spray heads 202 are evenly distributed at the bottom of the spray chamber 201, and the connection port 203 is connected to the top of the spray chamber 201. The support rod 204 is fixedly connected to the periphery of the spray chamber 201, and the bottom of the spray chamber 201 faces the top opening of the cleaning tank. Fixed to the top of the cleaning tank by the support rod 204, the spray chamber 201 connects to an external water supply device via the connection port 203 at the top. High-pressure spray water is sprayed onto the ABS plastic in the cleaning tank through the evenly distributed spray heads 202 at the bottom of the spray chamber 201, cleaning impurities from the plastic surface and providing clean material for subsequent filtration and separation.

[0028] like Figure 1-5 As shown, the filter structure 3 includes a first filter plate 301, a second filter plate 302, and a drive shaft 303. The second filter plate 302 is located at the bottom of the first filter plate 301. A drive shaft 303 is fixedly connected to both the first filter plate 301 and the second filter plate 302. The drive shaft 303 is hinged to the inner side of the first side plate 101 and the second side plate 102, respectively, and is connected to a drive device. The first filter plate 301 and the second filter plate 302 form a grading and screening assembly. The two are hinged to the inner side of the first side plate 101 and the second side plate 102 via the drive shaft 303 and connected to the drive device. After washing, the plastic is rinsed by spray water. Small-diameter plastic particles pass through the filter plates with the water flow and enter the grid structure 4, while large-diameter plastic particles remain on the surface of the filter plates. The drive device drives the drive shaft 303 to rotate, causing the filter plates to tilt. The plastic slides into the corresponding discharge port 103 under the action of gravity, completing the sorting.

[0029] like Figure 1-5As shown, the grid structure 4 includes a mesh grid 401, a filter tank 402, a drain outlet 403, and a slag discharge trough 404. The filter tank 402 is located on one side of the mesh grid 401, and a filter screen is installed between the mesh grid 401 and the filter tank 402. The drain outlet 403 is connected to one side of the filter tank 402, and the slag discharge trough 404 is located on the other side of the mesh grid 401. The mesh grid 401 is installed at the bottom of the cleaning tank. The mesh grid 401 installed at the bottom of the cleaning tank receives the filtered spray wastewater. The filter screen between the mesh grid 401 and the filter tank 402 divides the wastewater into three parts: sediment settles at the bottom of the mesh grid 401, floating matter remains on the water surface, and the filtered water enters the filter tank 402 through the filter screen and is discharged through the drain outlet 403. The slag discharge trough 404 on the other side of the mesh grid 401 is used to collect floating matter from subsequent cleaning, achieving solid-liquid impurity separation in the wastewater.

[0030] like Figure 1-5 As shown, the wave structure 5 includes a linear electric cylinder 501, a shield 502, a transmission block 503, and an impact block 504. The linear electric cylinder 501 is covered by the shield 502. The drive end of the linear electric cylinder 501 is connected to the transmission block 503, and the transmission block 503 is fixedly connected to the impact block 504. The linear electric cylinder 501 and the shield 502 are fixedly installed on the inner sides of the first side plate 101 and the second side plate 102. The linear electric cylinder 501 is covered by the shield 502 to prevent water splashing. The linear electric cylinder 501 is fixed on the inner side of the first side plate 101 and the second side plate 102. The transmission block 503 connected to its drive end drives the impact block 504 to reciprocate to impact the water in the grid structure 4, generating directional waves. The waves push light debris such as microplastics floating on the water surface into the slag discharge tank 404, avoiding clogging of the filter screen and assisting in the cleaning of floating objects in the sewage.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In use, the recycled and damaged ABS plastic is fed into the first filter plate 301 through the inlet 105. The spray structure 2 is connected to the water supply device through the interface 203 to introduce high-pressure spray water into the spray chamber 201. The spray water is sprayed from the spray head 202 onto the plastic on the first filter plate 301 for cleaning. The first filter plate 301 and the second filter plate 302 have different filtration mesh sizes, allowing smaller plastic particles to pass through the filter plates and enter the grid structure 4 with the spray water. The cleaned plastic is driven by the drive device connected to the filter plate drive shaft 303, which rotates the filter plate. Under the action of gravity, the plastic is driven along the filter plate. The subsequent slopes lead to their respective discharge ports 103, which correspond to open material boxes. The spray water entering the mesh screen 401 generally contains sediments or floating objects such as microplastics. The floating objects are driven by the linear electric cylinder 501 of the wave structure 5 to drive the transmission block 503 and the striking block 504 to strike the water in the mesh structure 4, generating waves. As the waves are transmitted, the floating objects on the surface are discharged into the slag discharge tank 404. The sediments will settle directly at the bottom of the mesh screen 401. At the same time, the water that can be filtered is filtered through the filter screen to the water filter tank 402, completing the separation of various impurities in the sewage.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
