A separating and cleaning device for residual plastic films

Abstract

The invention relates to a separating and cleaning device for recovered residual plastic films. The separating and cleaning device is characterized in that the separating and cleaning device comprises a cleaning device, a film collecting device and a stalk collecting device; the separating and collecting device separates the residual plastic films from cotton stalks by utilization of solid-liquid two-phase separation principles; the separating and collecting device can separate the residual plastic films from the cotton stalks by utilization of the solid-liquid two-phase separation principles and can clean the residual plastic films; and reutilization after recovery of the residual plastic films is achieved. The separating and cleaning device is provided with two rows of staggered spraying heads with a certain angle. Strike of bubbles sprayed by the spraying heads and gas produced by explosive eruption allow water to surge, so that soil grains attached to the residual plastic films are washed out rapidly and the cleaning efficiency of the residual plastic films is high. The film collecting device and the stalk collecting device are respectively provided with grid plates. The grid plates are evenly distributed on rotary shafts and are arc-shaped, so that film collection and stalk collection are rapid and convenient. The separating and cleaning device is reasonable in layout, low in cost, convenient in operation, high in working efficiency, reduced in waste of labor, convenient to move and not limited to places.

Description

technical field [0001] The invention relates to a recovered residual membrane separation and cleaning device. Background technique [0002] At present, since the application of plastic film mulching technology in our country, due to the remarkable characteristics of early sowing, temperature increase, moisture conservation (water), inhibition of weed growth, early maturity, improvement of product quality, and increase of production and income in the whole growth period of crop cultivation, the technology is currently It has been promoted and applied to 29 provinces, municipalities, and autonomous regions, and the national film-laying planting area exceeds 8 million hectares. While the mulching technology is widely promoted, the pollution caused by mulch is becoming more and more serious. Plastic film is a polymer compound, which is extremely difficult to degrade under natural conditions and can exist in the soil for 200-400 years. Plastic mulch contains toxic substances su...

AI Technical Summary

Problems solved by technology

Plastic mulch contains toxic substances such as polyethylene or polyvinyl chloride, which can inhibit the growth of soil microorganisms and affect the quality of agricultural products; the residual film destroys the physical and chemical structure of the soil, making the soil's air permeability and water storage worse, and crops absorb The capacity of water and nutrients is reduced, which eventually makes it difficult for crops to germinate and germinate, and it is difficult for the root system to penetrate, resulting in reduced crop production

The recycling of plastic film is mainly regeneration and granulation, which requires high cleanliness of waste plastic film. However, the plastic film recycled by residual film recycling machinery currently contains a large number of branches, stems, leaves, weeds, and soil clods, which will cause serious damage to the reuse of plastic film. Therefore, we urgently need a high-cleaning rate recycling residual film separation and cleaning device, which is very important for the recovery and reuse of residual film and the reduction of white pollution.
