Multi-function high-efficiency livestock and poultry excrement treating device

Abstract

The invention discloses a multi-function high-efficiency livestock and poultry excrement treating device and the device comprises an excrement fermentation room, an insulated light-passing board arranged on the outside of the fermentation room. A ring-shaped hollow heater is arranged in the excrement fermentation room, the periphery of the heater is full of excrement, and the heater connects with a solar collector through a pipeline; an excrement feeding hole. is arranged on the top of the excrement fermentation room, and the excrement feeding hole is connected with a excrement transfer pump through a transfer piping, the excrement transfer pump is provided with a electromagnetic valve; a spiral extrusion dehydration and crushing discharging device is fixed on the bottom of the fermentation room, and the end of the extrusion device is a discharge hole of the fermentation room. The device makes full use of solar energy as heat source, featuring fast heating, good insulation, automatic feeding and perennial use. Hazardous substances are killed by maturing the excrement which can also generate beneficial bacterium and methane. The matured biogas residues and biogas liquid can be transported at any time and meet the requirements of national pollutant discharge.

Description

technical field [0001] The invention relates to a multifunctional and high-efficiency livestock and poultry excrement treatment device. Background technique [0002] Fecal pollution in animal husbandry has become more and more serious. As the government and the general public have higher and higher environmental requirements, feces treatment is becoming more and more important. [0003] At present, the treatment methods for pathogenic bacteria, insects, eggs, ammonia gas, hydrogen sulfate, methyl mercaptan, skato, etc. in livestock and poultry manure are as follows: First, use the high temperature season to cover the manure with plastic film and ferment it at high temperature for about 30 days. The second is to mix feces with quicklime and cover with plastic film to keep warm and ferment in the low temperature season. The above two methods require a large amount of labor, the working environment is poor, harmful substances and gases cannot be fully eliminated, and transport...

AI Technical Summary

Problems solved by technology

This method is difficult to handle and the working environment is extremely poor

The fifth is to put the feces into biogas digesters or anaerobic reaction tanks for treatment. This method has a long treatment period and is difficult to work

Sixth, the complete set of foreign system equipment includes hot blast stove, feeding device, stirring predryer, air flow dryer, unloader, waste gas treatment, which is expensive, complicated in process and high in power consumption

All of the above methods have prominent disadvantages and are not ideal. They lack efficient and rapid treatment or lack of efficient mechanization, the work is difficult, or they lack the complete elimination of harmful substances in feces, and there is still pollution.
