Description
Technical Field
[0001] The utility model relates to the technical field of feces sand separation and reuse, in particular to a drying and processing device for wet feces sand. Background Art
[0002] It is estimated that a dairy farm with a stock of 1,500 cows discharges 14,000 tons of fresh cow dung and 73,000 m3 of sewage annually. More dairy farms are choosing to raise cows in sand. The diameter of the sand used is generally 1 to 2 mm, and the thickness of the sand is more than 10 cm. For such large-scale breeding, the huge amount of manure and sand, it is crucial to separate and reuse manure and sand. The manure and sand separation process currently proposed has a slow separation speed, high pollution, high cost of the reuse process treatment system, and incomplete separation. This design proposes an automated treatment process mode for the separation of manure and sand mixtures, designs a new process flow for the subsequent recycling and reuse of manure, sand, and water, and combines the two process systems together using water circulation.
[0003] At present, there is no mature automated separation process model that can separate and recycle feces, sand and water.
[0004] There are several reasons for this:
[0005] 1. The reserves of manure-sand mixture are large, and small systems and equipment cannot process them on demand.
[0006] 2. Professional separation equipment is expensive and the cost is too high.
[0007] 3. Ordinary separation processes cannot achieve fully automatic processing, and cannot meet recycling standards after processing.
[0008] 4. The foreign matter contained in the manure-sand mixture cannot be automatically removed by either manual treatment or no treatment.
[0009] 5. There is no technology to separate feces from water and dry the fluffy feces after separation.
[0010] 6. There is no technology for treating the water contained in sand water and manure water by using water circulation treatment.
[0011] 7. There is no complete process system for the separation and reuse of manure-sand mixture.
