Novel rod liquid stirring type feces anaerobic fermentation device

Abstract

The invention discloses a novel rod liquid stirring type feces anaerobic fermentation device. The device comprises a fermentation tank, a dirt inlet and a dirt suction structure, a hollow stand columnis driven by a driving structure to rotate is arranged in the center of the fermentation tank, a hydraulic cylinder is arranged on the top of the hollow stand column, and the hollow stand column is divided into a suction cavity and a liquid discharge cavity; a piston rod of the hydraulic cylinder penetrates into the suction cavity and provided with a suction head dividing the suction cavity intoa vacuum cavity and a liquid suction cavity, a hollow liquid suction arm with a liquid suction opening is arranged on the outer wall of the liquid absorption cavity, and a liquid inlet check valve isarranged at the communication portion of the hollow liquid suction arm and the liquid suction cavity; multiple hollow liquid discharge arms provided with liquid discharge openings formed in the side walls are uniformly arranged on the outer wall of the liquid discharge cavity in the circumferential direction. According to the feces anaerobic fermentation device, the uniformly of fermentation solution mixing is greatly improved, the feces suspension effect is improved, and meanwhile the crusting phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of anaerobic fermentation, in particular to a novel rod liquid stirring type manure anaerobic fermentation device. Background technique [0002] At present, the national annual production of livestock and poultry manure is about 3.8 billion tons. Statistics show that the chemical oxygen demand discharged by the livestock and poultry farming industry reached 12.6826 million tons, accounting for 96% of the total emissions from agricultural sources; the emissions of total nitrogen and total phosphorus were 1.0248 million tons and 160,400 tons, respectively accounting for the total emissions from agricultural sources. 38% and 56% of the volume. Livestock and poultry manure has become the main source of agricultural source pollution. Livestock and poultry manure is a kind of resource, and how to efficiently use it has become a recognized problem. [0003] Anaerobic fermentation treatment of manure is a common way of res...
