Micro-plastic separation device

Abstract

The invention discloses a micro-plastic separation device, and belongs to the related field of environmental protection. The micro-plastic separation device comprises a main body, a water inlet cavity, a conical cavity, a separation cavity, a conical filter plate, a traction block and a pull rope, wherein the water inlet cavity, the conical cavity and the separation cavity are all arranged in the main body, are sequentially arranged from top to bottom, and are communicated with one another; and the diameter of the separation cavity is smaller than that of the water inlet cavity, a spindle is rotatably connected between the top end of the separation cavity and the bottom end of the water inlet cavity, the excircle surface of the spindle is in key connection with a shaft sleeve, the conical filter plate is fixedly arranged on the shaft sleeve, the diameter of the conical filter plate is equal to that of the separation cavity, the conical filter plate is in sliding connection with the separation cavity, and the upper end surface of the conical filter plate is a conical surface. According to the scheme, micro-plastics floating on the water surface are collected through the conical filter plate, and the micro-plastics rapidly fall off from the filter plate in the separation cavity through wind power from bottom to top and vibration of the conical filter plate.

Description

technical field [0001] The invention belongs to the field related to environmental protection, and more specifically relates to a microplastic separation device. Background technique [0002] Microplastics, which are plastic particles with a diameter of less than 5 mm, are a major carrier of pollution. Microplastics are small in size, which means higher specific surface area. The larger the specific surface area, the stronger the ability to adsorb pollutants. Some microplastics are plastic particles discharged into the water environment through rivers, sewage treatment plants, etc. Products, such as microplastic particles contained in cosmetics, or plastic particles and resin particles used as industrial raw materials. Density separation method is often used to extract microplastics in complex environmental media. This microplastic extraction method is cumbersome and complicated, and it often takes several or even dozens of hours to separate microplastics from denser sand o...

Problems solved by technology

[0003] Some existing microplastic separation equipment is difficult to achieve industrial control. Generally, it is necessary to manually add the liquid to be separated and the flotation agent, and then manually pick up the floating microplastics. The separation efficiency is low, and it is very wasteful of manpower, and Due to the small size of micro-plastics, it is easy to block the filter plate, while the filter plates of some existing micro-plastic separation equipment often use traditional filter plates, and the cleaning function of the filter plate is not good, so it is easy to block the filter plate , it is difficult to meet the needs of long-term use
