Double cyclone separating system for mulching film sand Technical Field The invention belongs to the field of mulching film sand and soil separation instruments, and particularly relates to a mulching film sand and soil double cyclone separation system. Background Xinjiang is used as the largest cotton planting base in China, and in the cotton planting process, plastic film mulching is a key measure for guaranteeing the yield, namely the plastic film can effectively play roles in water retention and heat preservation, is suitable for the drought and low-temperature climate characteristics of Xinjiang, and helps cotton to grow normally. However, at the same time, the large amount of mulching films are used to bring serious white pollution, destroy the soil structure and affect the growth of crops, so that the recycling of mulching films becomes an important measure for the green development of the agriculture in Xinjiang at present, and a plurality of enterprises put into the recycling industry of mulching films in disputes. In various links of recycling the mulching film, the separation treatment is a primary premise that a large amount of sand is mixed in the recycled mulching film, and the sand can seriously influence the subsequent recycling effect of the mulching film, so that the mulching film and the sand must be thoroughly separated first. At present, various mulching film and sandy soil separating devices exist in the market, a combined mode of cyclone separators and water washing is generally adopted in a core process, but the combined process has obvious congenital defects, and the recycling requirements of high efficiency and energy conservation are difficult to meet. On the one hand, the cyclone separator can greatly reduce the overall separation efficiency, the efficient separation of the mulching film and sandy soil cannot be realized, and the promotion of the subsequent treatment process is affected, on the other hand, the water washing process can improve the separation effect to a certain extent, and realize more thorough sandy soil removal, but the water resources in Xinjiang areas are extremely short, a large amount of precious water resources are consumed in the water washing process, the actual protection of local water resources is not met, the overall treatment cost of the mulching film is obviously increased, and the industrial large-scale popularization is not facilitated. In view of the above, there is an urgent need to develop a novel mulching film separating device, which meets two requirements simultaneously, namely, high separating efficiency, capability of rapidly and thoroughly separating mulching films from sandy soil, independence of a large amount of water resources, capability of meeting the standard of subsequent pyrolysis treatment after the mulching films are separated, and therefore, the bottleneck of the existing process is broken, and high-quality development of Xinjiang mulching film recycling industry is promoted.
