Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to a dewatering machine for recycled plastic pellets from waste agricultural film. Background Technology

[0002] Agricultural film, also known as thin-film plastic film, includes mulch film (also called agricultural mulch film), and its main component is polyethylene. It is primarily used to cover farmland, serving to increase soil temperature, maintain soil moisture, promote seed germination and rapid seedling growth, and suppress weed growth. Due to the non-biodegradable nature of plastics, discarded agricultural film in the fields not only wastes land and energy resources but also damages the ecological environment and reduces the yield and quality of agricultural products. Therefore, the method of processing waste agricultural film into plastic pellets for reuse is gradually being promoted.

[0003] After waste agricultural film is processed into plastic pellets, it needs to be washed and then dehydrated. Currently, dehydration is mostly carried out using a metal mesh channel spiral conveyor, but the water adsorbed on the surface of the plastic pellets is difficult to remove effectively. Utility Model Content

[0004] The purpose of this invention is to provide a waste agricultural film recycled plastic granule dewatering machine that combines drum spin drying and hot drying technologies to dewater recycled plastic granules, thereby improving the removal effect of water adsorbed on the surface of the plastic granules.

[0005] To achieve the above objectives, a waste agricultural film recycled plastic pellet dewatering machine is provided, comprising an equipment shell and a spin-drying drum. A support frame and an air outlet duct are fixedly connected to the inner wall of the equipment shell, and the air outlet duct is located below the support frame. Several joints are installed on the surface of the air outlet duct, and the joints penetrate the equipment shell. A drain pipe is connected to the lower middle part of the equipment shell. A support frame is fixedly connected to the top of the inner wall of the drain pipe. A fixing rod is welded to the upper middle part of the support frame. A waterproof motor is fixedly connected to the upper end of the fixing rod, and the output end of the waterproof motor faces upward. An embedded block is fixedly connected to the output end of the waterproof motor. The spin-drying drum passes through the middle of the support frame and the air outlet slot. The embedding block is embedded in the lower middle of the spin-drying drum. The top of the equipment shell is provided with a top cover, which is rotatably connected to the equipment shell via a hinge. A controller and a mounting plate are fixedly connected to the outer end of the equipment shell. An electric hot air blower is fixedly connected to the upper end of the mounting plate. An air distributor is fixedly connected to the air outlet of the electric hot air blower, and an external flexible hose is provided between the air distributor and the connector, which is connected through a connecting hose. A hot air outlet pipe is installed on the outer end of the equipment shell, and the height of the hot air outlet pipe is the same as that of the support frame. A support leg is fixedly connected to the lower end of the equipment shell. This device can combine drum spin-drying and hot drying technologies to dehydrate recycled plastic granules, improving the removal effect of water adsorbed on the surface of the plastic granules.

[0006] According to the aforementioned waste agricultural film recycled plastic pellet dewatering machine, a plurality of rollers are equidistantly arranged on the surface of the support frame, and the rollers penetrate the support frame and are rotatably connected to it. A rotating plate is rotatably connected to the upper part of the support frame, and the rollers roll at the lower end of the rotating plate. The outer top of the spin-drying cylinder includes a support plate, and the support plate is located at the upper end of the rotating plate. The rotating plate supports the spin-drying cylinder, and the rollers prevent the rotating plate from contacting the support frame, thereby reducing wear on the rotating plate.

[0007] According to the aforementioned waste agricultural film recycled plastic granule dewatering machine, a limiting block is fixedly connected to the lower end of the tray, and a limiting groove for the limiting block is provided at the upper end of the rotating plate. A lifting ring for hoisting is welded to the top of the tray. The limiting block and the limiting groove cooperate to drive the rotating plate to rotate when the spin-drying drum rotates, avoiding increased wear caused by relative rotation between the tray and the rotating plate of the spin-drying drum. The lifting ring facilitates the use of hoisting equipment by the operator to remove the dewatered plastic granules along with the spin-drying drum from the device, making it convenient to replace the new spin-drying drum containing plastic granules for further dewatering.

[0008] According to the aforementioned waste agricultural film recycled plastic granule dewatering machine, the spin-drying cylinder includes a connecting block, which is fixedly connected to the lower middle part of the spin-drying cylinder. The lower end of the connecting block has an embedding groove that engages with an embedding block. Several laser receivers are evenly installed in the embedding groove, and a laser emitter is installed in the embedding block. The engagement of the embedding block and the embedding groove facilitates the removal of the spin-drying cylinder from the device. Furthermore, the laser sensor and laser receivers allow a waterproof motor to adjust the embedding block when the spin-drying cylinder is placed into the device, enabling the embedding block to directly enter the embedding groove.

[0009] According to the aforementioned waste agricultural film recycling plastic pellet dewatering machine, a handle is fixedly connected to the upper end of the top cover. The handle facilitates the operator in opening the top cover.

[0010] According to the aforementioned waste agricultural film recycling plastic pellet dewatering machine, a drain outlet is provided at the bottom of the air outlet trough. The drain outlet is used to discharge water that is thrown into the air outlet trough when the spin-drying drum rotates.

[0011] The above solution has the following advantages: the waterproof motor drives the spin-drying drum to rotate at high speed to spin-dry the plastic granules, and the electric hot air blower inputs hot air into the equipment shell through the air outlet to dry the spin-dried plastic granules, thereby improving the dehydration effect of the plastic granules.
