[0002] With the rapid development of the global plastics industry, polystyrene (PS), as an important thermoplastic, has been widely used in many fields such as packaging, construction, and electronic appliances. However, the sharp increase in plastic waste, especially the problem of microplastics, has become an environmental problem of global concern. Microplastics, including polystyrene microplastics, are widely distributed in the environment due to their tiny size and difficult to degrade properties, posing a potential threat to the ecosystem.

Moreover, each removal process requires a large amount of water resources, which not only leads to a waste of water resources, but also increases operating costs. Utility Model Content

[0023] The effect achieved by the entire embodiment 1 is that when using the device to remove impurities from polystyrene microplastics, first, unscrew the threaded cover 206, inject a proper amount of water into the water tank 204 through the water inlet 205, then put the raw material into the inner bottom of the filter plate 202, and then start the first water pump 208 to extract the water stored in the water tank 204, and transport the water to the installation tank 201 through the first water pipe 207. In the installation tank 201, the microplastic particles and the impurities therein are effectively separated by the force of the water flow, and the elutriation operation is performed. After the elutriation operation is completed, the water valve 210 is immediately started to guide the water flow containing impurities into the filter through the outlet pipe 209. In the tank 211, the two filter screens 212 in the filter tank 211 filter impurities. The two filter screens 212 are made of activated carbon material. The activated carbon adsorption capacity is used to effectively capture and remove harmful or undesirable components such as organic matter, suspended particles, bad color and odor in the water flow, thereby achieving preliminary purification and improvement of water quality. Then, the second water pump 214 is started to extract the filtered water flow through the second water pipe 213 and transport it to the water storage tank 204, thereby achieving effective recovery and reuse of water resources. Under the action of the circulation mechanism 2, the water after impurity removal can be recycled and reused to avoid direct discharge of wastewater, thereby not only reducing operating costs but also saving water resources.

[0025] The effect achieved by the entire embodiment 2 is that, when the water is installed in the tank 201, the driving motor 31 at the bottom of the U-shaped frame 3 is first started, and the output end thereof drives the mounting plate 32 to rotate at a uniform speed. As the mounting plate 32 rotates, the filter plate 202 thereon also rotates synchronously, thereby ensuring that during the liquid impurity removal process, impurities can be more evenly and effectively captured by the filter plate, thereby improving the impurity removal efficiency and effect. A threaded connection is adopted between the mounting plate 32 and the filter plate 202. When the impurity removal operation is completed, the filter plate 202 can be easily separated and removed from the mounting tank 201 by simply loosening and removing the threaded rod connecting the two.

[0026] Working principle: When in use, the raw material is put into the inner bottom of the filter plate 202. Next, the first water pump 208 is started to extract the water stored in the water tank 204, and the water is transported to the installation tank 201 through the first water pipe 207. When the water enters the installation tank 201, the drive motor 31 is started to drive the installation plate 32 to rotate at a uniform speed, so that in the process of liquid impurity removal, impurities can be more evenly and effectively captured by the filter plate. After the elutriation operation is completed, the water valve 210 is started to guide the water out through the outlet pipe 209. The water flow is guided into the filter tank 211. At this time, the two filter screens 212 in the filter tank 211 filter out impurities. The two filter screens 212 are made of activated carbon material. The activated carbon adsorption capacity is used to effectively capture and remove harmful or undesirable components such as organic matter, suspended particles, bad color and odor in the water flow, thereby achieving preliminary purification and improvement of water quality. Then, the second water pump 214 is started to extract the filtered water flow through the second water pipe 213 and transport it to the water storage tank 204, thereby achieving effective recovery and reuse of water resources.
