Problems solved by technology

[0003] The existing soil microplastic separation device cannot effectively filter the microplastics in the soil. During the separation process, part of the soil becomes lumpy, which is easy to block the filter device, and the microplastics in the lumpy soil cannot be filtered out, resulting in microplastics. Plastics are poorly separated

Abstract

The invention provides a soil microplastic separation device, which belongs to the technical field of microplastic separation. The invention comprises: an installation box, a first round pipe, a cylinder, a pushing mechanism, a stirring mechanism, a separation mechanism, a turning mechanism and a filter mechanism, an installation cavity is arranged in the installation box, and the first round pipe is vertically fixed on the bottom of the installation box. On the upper side, the lower end of the first round pipe extends into the installation cavity and the end is coaxially fixed with a bellows, and the cylinder is coaxially fixed at the lower end of the bellows, and the pushing mechanism can push the cylinder along the first circle. The axis of the pipe moves up and down, the stirring mechanism can stir the soil and liquid in the chamber, the separation mechanism can separate the stirred soil and liquid in the chamber, and the turning mechanism can make the upper opening of the first circular pipe vertically Rotating upwards to vertically downwards, the filtering mechanism can filter the microplastics in the liquid flowing out from the opening at the upper end. The invention can improve the separation effect of microplastics in soil, and the operation is simple.

Description

technical field [0001] The invention belongs to the technical field of microplastic separation, and relates to a soil microplastic separation device. Background technique [0002] Microplastics refer to plastic particles with a diameter of no more than 5 mm. Agricultural mulch breaking, organic fertilizer application, sewage irrigation, sludge agricultural use, atmospheric deposition, and surface runoff have become sources of microplastics in soil, which may lead to microplastics in soil edible crops. The accumulation of plastics, the existence form, migration, degradation and environmental risks of microplastics entering the soil, the accumulation in animals and plants and the risks of their biological ecology and food chain, and the risks to human health, so it is necessary to remove the microplastics in the soil Microplastics filter out. [0003] The existing soil microplastic separation device cannot effectively filter the microplastics in the soil. During the separatio...
