Solid-liquid separation system

Abstract

The invention discloses a solid-liquid separating system, and belongs to the field of aquacultural machinery. The solid-liquid separating system comprises a solid-liquid separating device, a sewage collecting tank, a mixer and a water pump; the solid-liquid separating device comprises a machine body and a sieve net; an inclined water outlet plate is arranged at the bottom part of the machine body; a water outlet is formed in the lower end of the water outlet plate; the sieve net is obliquely arranged on the top part of the machine body; the mixer and the water pump are both arranged in the sewage collecting tank; the water pump is communicated with the higher end of the sieve net through a water pipe. With the adoption of the solid-liquid separating system, the solid-liquid separation of excrement and sewage can be effectively realized, and the excrement leaves and water can be recycled at the same time; the solid-liquid separating system is simple in structure, easy to operate, small in occupied area, and good in effects of saving time and force and treating, effectively solves the problem that the excrement leaves are difficult to treat, realizes environmental protection, and increases the economic benefit of a livestock farm.

Description

technical field [0001] The invention relates to the field of farming machinery, in particular to a solid-liquid separation system. Background technique [0002] In the daily production process, pig farms generally do not take the initiative to collect dry manure, but directly wash it with water, so that a large amount of manure enters the biogas digester every day. Generally speaking, the fermentation time of feces in the biogas tank is long, and some of them cannot be decomposed. However, the capacity of the biogas tank is limited. In the long run, a large amount of unfermented and undecomposed pig manure will be deposited in the biogas tank. , causing the biogas digester to be clogged and unusable; on the other hand, crusting will occur in the pond, making the effective volume of the biogas digester smaller and smaller, and the treatment effect is getting worse. Some pig farms will use methods such as setting up slag separation tanks and sedimentation tanks to deal with d...
