Description

Technical Field

[0001] The utility model relates to the technical field of pig manure processing equipment, in particular to a pig manure solid-liquid separator. Background Art

[0002] In the current vigorous development of animal husbandry, especially the gradual maturity of pig breeding technology, the output and number of pigs are getting higher and higher, which leads to a large amount of pig manure in the breeding process. At present, when dealing with pig manure, it is usually necessary to consider environmental protection and resource utilization. Therefore, it is necessary to separate the solid and liquid of the pig manure and collect it for recycling. When performing solid-liquid separation, a pig manure solid-liquid separator is needed.

[0003] In the prior art, such as the publication number: CN215427509U, a solid-liquid separation device for processing pig manure organic fertilizer is disclosed, which includes a box, a filter plate, a baffle, a liquid receiving box, a material receiving box and an air jet pipe; the rotating material-dividing assembly includes a first rotating shaft, an L-shaped plate, bristles and a sprocket; the filter plate is tilted downward and arranged on the right inner wall of the box; two groups of baffles are vertically arranged on the filter plate; the first rotating shaft is rotatably arranged on the rear wall of the box; the L-shaped plate is arranged on the first rotating shaft; the bristles are arranged on the first rotating shaft; the sprocket is connected to the first rotating shaft; multiple groups of rotating material-dividing assemblies are arranged; a first power device that drives the first rotating shaft to rotate is arranged on the rear wall of the box; the liquid receiving box and the material receiving box are arranged on the inner side of the bottom of the box, the liquid receiving box is located below the filter plate, and the material receiving box is located below the lowest point of the filter plate; the air jet pipe is arranged on the right inner wall of the box. In the utility model, the solid-liquid separation effect is good, and the problem of difficulty in feeding caused by pig manure sticking to the filter plate can be prevented.

[0004] However, the device still has some problems. The pig manure on the filter plate is continuously scraped and moved by an L-shaped plate so that the liquid can be separated quickly. However, in actual use, the solid part of the pig manure will be soaked in urine during transportation. Long-term soaking will cause the solid part to absorb a certain amount of urine. When performing solid-liquid separation, the urine absorbed by the solid part cannot be separated by conventional gravity filtration, which leads to the problem of poor solid-liquid separation effect. Therefore, we disclose a pig manure solid-liquid separator to meet people's needs. Utility Model Content
