Solid-liquid separation device

Abstract

The invention relates to a farmyard manure treatment device, in particular to a solid-liquid separation device. The technical problem to be solved by the invention is to provide the solid-liquid separation device. A solid-liquid separation device comprises a connecting machine bottom plate, a climbing inclined table, a surface rough layer, a fecal suction truck discharging table, a circulating separation mechanism, a light crushing mechanism, a secondary separation mechanism and the like. The left side of the top end of the connecting machine bottom plate is connected with the climbing inclined table. According to the invention, the fecal suction truck can also climb and obliquely discharge on the flat ground, so human excrement and urine in the excrement suction truck can be poured out without residues; meanwhile, the human excrement and urine mixture is subjected to classification treatment, the liquid part and the solid part are separated, the human excrement is subjected to fragmentation treatment so that the human excrement cannot be dried or accumulated; toilet paper, sanitary towels and other non-degradable garbage mixed in the human excrement and urine mixture are removed,and the effect that pure human excrement and urine can be directly used for farmyard manure production and utilization is realized.

Description

technical field [0001] The invention relates to a farmyard manure processing device, in particular to a solid-liquid separation device. Background technique [0002] Solid-liquid separation refers to the process of separating the two phases from the solid-liquid two-phase system. [0003] In the prior art, human excrement and urine are usually used to make farmyard manure to play its greatest role, and it can be treated without accumulating and polluting the environment. Due to the relatively backward facilities in rural areas, the garbage treatment facilities are not perfect, and the farmhouses The fertilizer fermentation system is not popular enough, which leads to the fact that the existing human excrement and urine mixture is directly discharged into the farmland, making it fermented by itself, as natural compost, and then absorbed by the land, but there are other non-degradable white fertilizers such as toilet paper and sanitary napkins in the human excrement and urine ...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the fact that the existing human excrement and urine mixture is directly discharged into the farmland due to the relatively backward conditions of rural facilities, insufficient garbage treatment facilities, and insufficient popularization of the farmyard manure fermentation system, so that it can be fermented by itself and used as natural compost. However, there are other non-degradable white pollutants such as toilet paper and sanitary napkins in the mixture of human feces and urine, which cause such white pollutants to stay on the surface of the farmland. At the same time, some human feces are dry and cannot be absorbed by the land and plants. It is inconvenient to plant crops, and at the same time, the farmland ecosystem is polluted and destroyed, and the tank body of the existing fecal suction truck lacks a power source for feeding, and some human excrement and urine are often retained inside. The technical problem to be solved by the present invention is to provide a solid-liquid separation device
