Sewage purification and separation equipment for pig breeding

Abstract

The invention belongs to the technical field of livestock breeding, particularly relates to sewage purification and separation equipment for pig breeding. The invention aims to solve the problems that the whole sewage treatment process is slow and large-scale treatment of sewage of pig breeding is hard since the sewage of pig breeding is directly discharged into a sewage pool and initial solid-liquid separation is not carried out at present. According to a scheme in the invention, the sewage purification and separation equipment comprises a separation barrel, wherein a feeding shaft is arranged between and movably connected with the inner walls of the two sides of the separation barrel; the feeding shaft is in a circular truncated cone shape; a spiral feeding blade is fixedly connected to the outer wall of the feeding shaft; a plurality of grabbing protrusions are fixedly connected to the outer wall of one side of the spiral feeding blade; a plurality of leakage holes are formed in the barrel wall of the lower side of the separation barrel; a groove is formed in the outer wall of the lower side of the separation barrel; and a filter plate is fixedly connected to the inner wall of the groove. According to the invention, solid-liquid separation can be completed in the feeding period of the sewage, so influence on the whole subsequent treatment process is avoided; and doping solid impurities in the sewage can be spirally fed and extruded, so solid-liquid separation effect is improved.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a sewage purification and separation device for pig breeding. Background technique [0002] Breeding refers to the cultivation and reproduction of animals and plants. Breeding includes livestock breeding, poultry breeding, aquaculture and special breeding. Pork is the most important edible meat in my country, and its demand is very huge. As an important component of the pork industry, the foreign trade of pork also occupies a huge proportion of the national economy. [0003] During the pig breeding process, a large amount of sewage will be produced, and the untreated sewage will seriously pollute the water resource environment. The current main treatment method is to discharge the sewage directly into the sewage tank for sedimentation and filtration treatment. Treatment, the whole sewage treatment process is slow, and cannot meet the needs of large-scale pig breeding. ...
