Livestock farm excrement treatment system

Abstract

The invention discloses a livestock farm excrement treatment system which comprises a livestock house, a livestock excrement solid-liquid separator, an irrigation pool and a centrifugal pre-separation device. Excrement leaking holes are fully distributed in a floor, used for breeding livestock, in the livestock house, a trench is arranged outside the livestock house, an excrement groove is formed in the trench, a discharging pipe of the centrifugal pre-separation device is connected with a feeding port of the livestock excrement solid-liquid separator, and an overflow port and a liquid-state outlet of the livestock excrement solid-liquid separator are communicated with the irrigation pool through pipelines respectively. The livestock farm excrement treatment system realizes two-step separation through the centrifugal pre-separation device and the livestock excrement solid-liquid separator, and treatment of livestock excrement is more convenient, quick and efficient, so that environment can be protected effectively. The livestock farm excrement system can be used for breeding large livestock like pigs, sheep, cattle and donkeys.

Description

technical field [0001] The invention relates to livestock breeding equipment, in particular to a livestock farm excrement treatment system. Background technique [0002] In modern society, the breeding industry of livestock is more and more developed, so most of the livestock are raised in a centralized way, but this kind of breeding method has higher requirements for the treatment of manure. If the concentrated manure cannot be effectively treated It will cause great environmental pollution, and the existing treatment of livestock manure mainly adopts animal manure solid-liquid separator to reduce the pollution of animal manure to the environment. [0003] The processing method of the animal manure treatment system in the prior art is as follows: the animal manure and manure are collected in the manure tank, and then the solid manure and liquid manure in the manure tank are sent to the solid-liquid separator through a special delivery pump Solid-liquid separation is achi...

Problems solved by technology

[0002] In modern society, the livestock breeding industry is more and more developed, so most of the livestock are raised in a concentrated manner, but this kind of breeding method has higher requirements for the treatment of manure. If the concentrated manure cannot be effectively treated It will cause great environmental pollution, and the existing treatment of animal manure mainly uses animal manure solid-liquid separator to reduce the pollution of animal manure to the environment

[0003] The processing method of the animal manure treatment system in the prior art is as follows: the animal manure and manure are collected in the manure tank, and then the solid manure and liquid manure in the manure tank are sent to the solid-liquid separator through a special delivery pump Solid-liquid separation is realized in the septic tank, but most of the manure in the septic tank is liquid manure, and the solid animal manure is easy to liquefy as soon as it enters the septic tank. When the special delivery pump starts to work, the manure will drive the animal manure in the manure tank. Continuous movement, especially after the rain, the amount of liquid manure will increase again. The solid animal manure only accounts for a very small part of the material pushed into the solid-liquid separator by the special delivery pump. The solid-liquid separator separates The efficiency is very low, which greatly reduces the working efficiency of the livestock manure treatment system, which can not realize the effective separation of solid manure and liquid manure, and wastes a lot of power resources
