Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a dust removal and cleaning mechanism for polyethylene recycling. Background Art

[0002] Polyethylene is a widely used plastic with good toughness, corrosion resistance and insulation properties. However, a large amount of polyethylene waste has caused serious pollution to the environment. Therefore, the recycling of polyethylene is of great importance. At present, in the recycling process of polyethylene, in order to facilitate reuse, polyethylene needs to be shredded, that is, polyethylene is shredded into granules.

[0003] The utility model patent with authorization announcement number CN214078170U discloses an environmental protection device for cleaning high-density polyethylene recycled particles, which includes a pool and a cleaning device, wherein a first motor and a second motor are fixedly connected to the two sides of the pool respectively, one end of the second motor passes through the pool and is fixedly connected to a cam, a slider is slidably connected to the inside of the pool, an electric telescopic rod is fixedly connected to the upper end of the slider, and a roller is movably connected to the end of the electric telescopic rod away from the slider, a rotating shaft is slidably connected to the inside of the pool, a cover cloth is fixedly connected to the surface of the rotating shaft, the side wall of the cover cloth is slidably connected to the inner wall of the pool, and the end of the cover cloth away from the rotating shaft is fixedly connected to the pool, a discharge port is opened at the end of the pool away from the rotating shaft, and two blocks are fixedly connected to one end of the discharge port, and a cleaning device is provided inside the pool; by setting the cleaning device, the problem that it is difficult to completely clean and remove the polyethylene particles, which will cause polyethylene particles to remain in the cleaning pool, is solved.

[0004] Although the high-density polyethylene recycled particle cleaning and environmental protection device is convenient for collecting the polyethylene particles cleaned in the cleaning pool, the device still has the following problems in actual use: after cleaning, a large amount of water stains often adhere to the surface of the polyethylene particles, which makes it impossible to directly put the particles into the subsequent processing equipment, but must be transferred to special drying equipment first, and then undergo tedious drying or drying. This process not only increases the complexity of the operation, but also inevitably affects the recovery and reuse efficiency of polyethylene particles, thereby restricting the efficient implementation of the entire recycling process to a certain extent. In view of this, we propose a dust removal and cleaning mechanism for polyethylene recycling. Utility Model Content
