Embodiment Construction

[0022] The present invention will be further described in detail through the drawings and examples below. Through these descriptions, the features and advantages of the present invention will become more apparent. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them.

[0023] like Figure 1-3 , the novel rod-liquid agitating type manure anaerobic fermentation device shown comprises a fermenter, a hydraulic device 1, a sewage suction pump 17 and a sewage suction pipe 18, and a sewage inlet 19 is arranged on the top 7 of the fermenter tank. The center of the tank is provided with a hollow column, and the two ends of the hollow column are closed. The hollow column is driven to rotate through the driving structure. Specifically, the driving structure includes a hydraulic motor 21 and a hydraulic turntable 22. The hollow column is installed on the hydraulic turntable. superior. The top of the hollow column is provid...

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...
