Dry and wet livestock manure treatment device

Abstract

A dry and wet livestock manure treatment device comprises a fermentation tower (1), a motor (2), a reducer (3), a feeding and turning screw conveyor (4), a belt pulley A (5), a hopper (6), a material channel (7), a belt pulley B (8), a shifting piece (9), a shifting rod (10), a group of aerator pipes (11) and a temperature sensing bushing (12). The dry and wet livestock manure treatment device has the advantages as follows: the feeding and turning screw conveyor is adopted for feeding and turning, can treat dry and wet raw materials simultaneously and can perform repeated turning, and the fermentation effect is good; the temperature in the fermentation tower can be monitored and regulated in real time, the fermentation efficiency is high, and inactivation of fermentation bacteria due to overhigh temperature is avoided; by means of a check valve, an anaerobic environment in the fermentation tower can be guaranteed, waste gas generated in a fermentation process can be exhausted, the fermentation tower inside is enabled to be in a good fermentation environment, and the fermentation quality is improved.

Description

technical field [0001] The invention relates to the field of livestock and poultry manure treatment, in particular to a wet and dry livestock and poultry manure treatment device. Background technique [0002] With the adjustment of the agricultural industrial structure, the scale of livestock and poultry breeding is rapidly expanding, and the output of livestock and poultry manure is also increasing day by day. More than 80% of the farms do not have manure treatment facilities. The high concentration of manure not only pollutes the surrounding environment, but also causes , A large loss of phosphorus, the loss is about 122% and 132% of the loss of chemical fertilizers. In addition, harmful bacteria and insect eggs in feces spread diseases among livestock and poultry, leading to the spread of diseases such as avian influenza, which seriously restricts the sustainable development of livestock and poultry breeding.

AI Technical Summary

Problems solved by technology

In addition, harmful bacteria and insect eggs in feces spread diseases among livestock and poultry, leading to the spread of diseases such as avian influenza, which seriously restricts the sustainable development of livestock and poultry breeding.

[0003] At present, compost fermentation and tank fermentation are mostly used in the production of organic fertilizers. Although the problem of fermentation has been solved, the turning device used in the existing fermentation tower can only turn the material once, and it is difficult to turn the material multiple times. The temperature cannot be well controlled. The fermentation temperature is too low and the fermentation speed is slow, or the temperature is too high and the fermentation bacteria lose their activity, which affects the fermentation effect.
