Description

Technical Field

[0001] This utility model belongs to the field of plastic cleaning technology, specifically relating to a waste plastic cleaning device. Background Technology

[0002] Waste plastics refer to all plastics that have been used and eventually discarded or replaced in civilian and industrial applications. They can be categorized according to their reuse methods: recycled plastics, reprocessed plastics, recycled plastics, reusable plastics, recyclable plastics, and non-recyclable plastics. Plastic recycling processes include collection, sorting, cleaning, drying, granulation, and molding. Currently, plastic cleaning generally relies on high-speed nozzles for rinsing combined with agitation by a flapper plate. However, this method requires a water tank of at least 10 meters, and the longer the tank, the better the cleaning effect. Furthermore, traditional rinsing methods cannot guarantee complete cleaning of the plastics. Therefore, we provide a waste plastic cleaning device to solve these technical problems. Summary of the Invention

[0010] (1) The waste plastic cleaning device of this utility model has a simple structure and is convenient and practical. It soaks and rinses plastic particles by soaking and rinsing them in a water tank, so that the dirt attached to the surface of the plastic particles softens or even falls off, thereby improving the cleaning efficiency of the particles.

[0011] (2) The waste plastic cleaning device of this utility model drives the feed pipe and the arc-shaped bottom plate to rotate through the power device, so that the brush can quickly brush the plastic. At the same time, the spiral setting of the brush makes it easy for the plastic to enter between the arc-shaped bottom plate and the arc ring for easy plastic brushing. Attached Figure Description

Detailed Implementation

[0013] The embodiments of this utility model are further described below with reference to the accompanying drawings. Example

[0014] like Figures 1 to 2As shown; a waste plastic cleaning device includes an immersion and rinsing water tank 1, an isolation mesh box 2, rinsing pipes 3, a flow direction pipe 4, a feeding screw conveyor 5, a discharging screw conveyor 7, and a scrubbing device 8. The immersion and rinsing water tank 1 is connected to the feeding screw conveyor 5 on one side and to the discharging screw conveyor 7 and scrubbing device 8 on the other side. The isolation mesh box 2 is connected to the top of the immersion and rinsing water tank 1. Several rinsing pipes 3 are arranged inside the isolation mesh box 2. The flow direction pipe 4 is connected to the inner wall of the immersion and rinsing water tank 1 near the feeding screw conveyor 5. Several duckbill nozzles are provided on both the rinsing pipes 3 and the flow direction pipe 4. The scrubbing device 8 includes a water tank 81, a positioning ring 82, an arc-shaped base plate 84, an arc-shaped ring 86, a feeding pipe 88, and a spiral blade. 89. A fixed frame 810 and a power unit are included. The arc-shaped base plate 84 is connected to the water tank 81 via a positioning ring 82. The feed pipe 88 passes through the top of the water tank 81 and is connected to the arc-shaped ring 86, and is fixed by the fixed frame 810. The feed pipe 88 is movably connected to the water tank 81. Several brushes 85 are evenly arranged on one side of the arc-shaped ring 86 near the arc-shaped base plate 84. The water tank 81 is provided with a guide port 83 and a discharge pipe 87 on both sides. The feed pipe 88 is connected to the power unit. The spiral blade 89 is located inside the end of the feed pipe 88 near the arc-shaped ring 86. A sedimentation isolation screen 6 is provided inside the soaking and rinsing water tank 1. A layer of fleece is provided on the arc-shaped base plate 84. Several brushes 85 are arranged in a spiral shape.

[0015] The crushed plastic granules are conveyed to the soaking and rinsing water tank 1 via the feeding screw conveyor 5. The plastic granules float to the surface and are then rinsed by water sprayed through the duckbill nozzles on the rinsing pipe 3. Water sprayed from the duckbill nozzles on the pipe 4 causes the floating plastic to flow towards the discharge screw conveyor 7. A separating mesh box 2 keeps the floating plastic granules a distance from the duckbill nozzles on the rinsing pipe 3, ensuring effective rinsing. Simultaneously, water in the soaking and rinsing water tank 1 overflows from the outlet of the discharge screw conveyor 7, along with the plastic granules, falling into the feeding pipe 88. This completes the process. The plastic granules are rinsed and soaked. The feed pipe 88 is rotated by the power device, which drives the arc ring 86 to rotate. The plastic granules and water fall onto the arc base plate 84. At the same time, under the action of the spiral blade 89, the plastic granules are driven between the arc ring 86 and the arc base plate 84. Then, with the help of the spiral brush 85, the plastic granules are conveyed and brushed. The brushed plastic granules are thrown into the space between the inner wall of the water tank 81 and the positioning ring 82. The water is discharged through the guide port 83, so that the plastic granules floating between the inner wall of the water tank 81 and the positioning ring 82 flow out through the discharge pipe 87.
