Stirring device for livestock manure full-mixing type fermentation tank

Abstract

The invention relates to a stirring device of a livestock manure full-mixing type fermentation tank. The stirring device comprises a fermentation tank, a stirrer and a hydraulic motor component, wherein the fermentation tank is used for accommodating a livestock manure mixed medium; the stirrer is positioned in the fermentation tank; and the hydraulic motor component serving as a power source directly drives the stirrer to rotate. The stirring device has a compact structure, is convenient to install and operate, safe, reliable and high in corrosion resistance, and hardly triggers safety accidents such as a fire hazard, explosion, methane leakage and the like.

Description

technical field [0001] The invention belongs to the technical field of energy recovery of environmental engineering, and in particular relates to a stirring device for a full-mix fermenter of livestock and poultry manure. Background technique [0002] At present, due to the light weight and low price of the motor, it is widely used in production and life. At present, the agitator of the livestock and poultry manure fermentation tank is mainly powered by an external motor, but this kind of agitator has the following problems: First, the external motor must be operated with electricity, which requires extremely high fire protection, explosion protection and sealing technology for the entire fermentation system , a slight improper operation may easily lead to safety accidents; the second is that the raw material for the fermentation of livestock and poultry manure has a high concentration and many impurities such as feces and grass, which is easy to entangle the agitator. The ...

Problems solved by technology

At present, the agitator of the livestock and poultry manure fermentation tank is mainly powered by an external motor, but this kind of agitator has the following problems: First, the external motor must be operated with electricity, which requires extremely high fire protection, explosion protection and sealing technology for the entire fermentation system , a slight improper operation may easily lead to safety accidents; the second is that the raw material for the fermentation of livestock and poultry manure has a high concentration and many impurities such as feces and grass, which is easy to entangle the agitator. The motor is damaged, etc.; the third is to install a speed change device, the size of the equipment is large, and installation and maintenance are troublesome.

And the motor drives the stirring paddle in the fermenter to stir the medium through the transmission device and the transmission shaft. The structure of this stirring device is complicated, and there are many intermediate links, which will inevitably bring about the problem of excessive explosion-proof hidden dangers and the possibility of seal leakage. Moreover, because the shaft seal is often damaged, the service life is short, and the failure shutdown is frequent, which not only increases the cost of equipment maintenance and replacement, but also pollutes the environment
