Sufficient-grinding biogas slurry pretreatment device

Abstract

The invention discloses a sufficient-grinding biogas slurry pretreatment device which comprises an organic fertilizer collection tank, wherein a feed port is formed at the top on one side of the organic fertilizer collection tank; a discharge port and a gas outlet above the discharge port are formed on the other side of the organic fertilizer collection tank; a motor is arranged above the organicfertilizer collection tank; an output shaft of the motor is connected with the top end of a stirring shaft; the bottom end of the stirring shaft penetrates through the top end of the organic fertilizer collection tank and is connected with a bearing seat at the bottom end in the organic fertilizer collection tank; a gear I is sleeved with the organic fertilizer collection tank on the stirring shaft; multiple gears II uniformly surround the outer side of the gear I; a toothed ring is sleeved with the outer sides of the gears II; the outer side of the toothed ring is connected with the inner wall of the organic fertilizer collection tank through a support frame; a fixing ring is sleeved between the gear I and the bearing seat on the stirring shaft. The sufficient-grinding biogas slurry pretreatment device disclosed by the invention has the following beneficial effects: the contact area between a cutter group and the waste is increased, and the grinding efficiency and the grinding qualityof the cutter group are improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer treatment equipment, in particular to a fully pulverized biogas slurry pretreatment device. Background technique [0002] Biogas slurry is the residue after anaerobic fermentation of high-concentration organic wastewater, livestock and poultry manure, crop straw, etc. Enhance the photosynthetic ability, and at the same time, realize the simultaneous application of fertilizer and water. Almost all the biogas slurry infiltrates into the cultivation layer with water, effectively preventing the loss of nutrients in the biogas slurry. It can be used as drip irrigation fertilizer for vegetables in the greenhouse, which can reduce the humidity in the greenhouse and reduce the occurrence of diseases. Promote the growth of vegetables, reduce the pollution of chemical fertilizers, produce pollution-free vegetables, easy to operate and so on. At present, it is usually difficult for the biogas s...
