Description

Technical Field

[0001] This utility model relates to the field of plastic scrap recycling technology, specifically to a cleaning device for plastic scrap. Background Technology

[0002] Plastic scraps are leftover materials generated during industrial production from cutting, trimming, or injection molding, such as sheet scraps and injection molding sprues. They are essentially still plastic raw materials, but due to their irregular shapes, they cannot be directly used to manufacture the original products. Moreover, most plastic scraps are piled up in waste areas and will be covered with impurities such as oil, dust, and metal shavings. Cleaning is an essential core step when reusing them. If they are not thoroughly cleaned, the recycled products will have bubbles, cracks, or degraded performance.

[0003] Cleaning devices are used to clean plastic scraps, but traditional cleaning devices mostly use static soaking or one-way rinsing, which is difficult to thoroughly remove stubborn stains from the gaps in the scraps. In addition, they lack the design to turn over irregular materials, and the accumulation of materials during the cleaning process leads to blind spots in local cleaning. Therefore, there is an urgent need to design a cleaning device for plastic scraps to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for plastic scraps to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for plastic scrap includes a cleaning tank. Two support legs are bolted to each of the two outer walls at the bottom of the cleaning tank. A feeding box is bolted to one outer wall of the cleaning tank, and a feeding hopper is bolted to the top outer wall of the feeding box. An impeller is mounted inside the feeding hopper via bearings. A pulley is mounted to one end of the impeller via a key. Two electric rollers are mounted inside the feeding box via bearings, and a belt connects the two electric rollers. A pulley is mounted to one end of one of the electric rollers via a key, and a synchronous belt connects the pulley and pulley. A spray plate is bolted to the top outer wall of the feeding box. A water pump is bolted to the bottom outer wall of the feeding box and connected to the cleaning tank and spray plate via a pipe. An installation cylinder is mounted inside the cleaning tank via bearings, and eight grid plates are bolted to the outside of the installation cylinder. A drive motor is bolted to one outer wall of the cleaning tank, and the output end of the drive motor is connected to the installation cylinder via a coupling.

[0006] Furthermore, a discharge box is bolted to one side of the bottom outer wall of the cleaning box, and a sliding groove is provided on one side of the outer wall of the discharge box. A bottom plate is slidably inserted into the discharge box, and one end of the bottom plate is slidably inserted into the sliding groove.

[0007] Furthermore, an electric push rod is bolted to one side of the outer wall of the discharge box, and the output end of the electric push rod is bolted to the base plate.

[0008] Furthermore, a heating module is bolted to one side of the outer wall of the top of the cleaning tank. The heating module includes a tank shell, and a bent-tube heater is bolted to the inside of the tank shell. An air inlet is provided on one side of the outer wall of the tank shell.

[0009] Furthermore, a blower is bolted to one side of the outer wall of the cleaning tank, and an air supply pipe is bolted to the other side of the outer wall of the blower. One end of the air supply pipe is connected to the tank shell through an air inlet.

[0010] Furthermore, an air inlet is provided on one side of the outer wall of the top of the cleaning tank, and the tank shell is connected to the cleaning tank through the air inlet. A filter screen is installed inside the air inlet by bolts.

[0011] In the above technical solution, the plastic scrap cleaning device provided by this utility model has the following advantages: This invention achieves uniform feeding distribution through a synchronous belt-driven impeller, preventing material accumulation. The high-pressure water jet from the spray plate thoroughly destroys the surface of the material where dirt adheres. The subsequent installation cylinder drives the eight grid plates to rotate, allowing scraps to continuously tumble within the cleaning tank. This breaks through the traditional static soaking mode and solves the problem of cleaning dead corners caused by traditional static soaking.

[0012] The heating module of this invention works in conjunction with a blower to send hot air, filtered through a screen, into the cleaning box to directly dry the wet material carried by the upper grid plate, thus shortening the production cycle.

[0013] When cleaning plastic edges and corners, this invention starts a water pump that can transport wastewater from the cleaning tank to the spray plate for reuse, greatly reducing water consumption and meeting the requirements of green manufacturing.

[0014] This utility model uses an electric push rod to drive the base plate to slide within the chute, achieving precise opening and closing of the discharge box and automatic material discharge, which greatly improves efficiency compared to the traditional manual retrieval method.

[0028] This embodiment further defines the features of Embodiment 1.

The hot air directly acts on the wet material on the grid plate 17 to achieve in-situ drying.

[0029] Working principle: When material enters through the feed hopper 10, the electric drum 14 drives the belt 15 to rotate. The synchronous belt 24 links pulleys 22 and 23, causing the impeller 13 to rotate, achieving uniform material dispersion and preventing accumulation in the feed box 9. During this process, the water pump 11 pumps water from the cleaning tank 1 into the spray plate 12 via pipes. The high-pressure water flow initially washes the falling material, breaking down the surface dirt layer. Meanwhile, the belt 15 continuously conveys the material to the cleaning tank 1. As the material is conveyed by the belt 15, it enters the cleaning tank 1. Once inside, the drive motor 21 drives the mounting cylinder 16 to rotate via a coupling. The eight grid plates 17 rotate accordingly, creating a tumbling cleaning environment. The grid structure ensures full contact between the material and the water flow. Simultaneously, centrifugal force promotes the removal of dirt, and during the washing process, water pump 11 continuously pumps the wastewater at the bottom of the washing tank 1 back into the spray plate 12 to form a closed-loop water circulation. Filter screen 19 simultaneously intercepts impurities to prevent system blockage. After washing, the drain pipe on one side of the washing tank 1 is opened, and the water inside the washing tank 1 flows out. Then, the blower 5 is started, and the blower 5 sends air into the heating module 4 through the air supply pipe 6. The bent-tube heater 27 heats the air, which is then filtered through the filter screen 19 and enters the washing tank 1 through the air inlet 18 to perform penetrating drying on the wet material on the grid plate 17. After the material is dried, the electric push rod 20 pushes the bottom plate 8 to move along the slide 7, opening the discharge box 3 to achieve automatic unloading. After the bottom plate 8 is reset, the entire processing cycle is completed.
