Organic fertilizer fermentation tank

Abstract

The invention discloses an organic fertilizer fermentation tank, which has a left slurry tank and a right slurry tank. The left slurry tank and the right slurry tank together enclose an open-type fermentation tank body, the fermentation tank body is equipped with a material turnover device, several groups of aeration and liquid dung recovery systems are disposed in the fermentation tank body, and each group of aeration and liquid dung recovery system includes a water collection pool, a high pressure air pump, a water collecting pipe, a gas pipe and a plurality of aeration pipes, wherein the tank edge of the water collection pool is flush with the ground, the water collection pool is connected to the water collecting pipe, the water collecting pipe is connected to the gas pipe and the aeration pipes, the aeration pipes are provided with air holes, the water collecting pipe between the gas pipe and the water collection pool is equipped with a switch valve A, a gas input end of the gas pipe is connected to a high-pressure air pump, and the gas pipe is equipped with a switch valve B. The bottom of the fermentation tank is provided with several water collecting grooves, and an aeration pipe is embedded in each water collecting groove. The organic fertilizer fermentation tank provided by the invention promotes aerobic fermentation of materials accumulated in the fermentation tank body, prevents the pollution of liquid dung in the fermentation tank to the environment, and achieves good economic benefits.

Description

technical field [0001] The invention relates to a fermentation device, in particular to an organic fertilizer fermentation tank. Background technique [0002] At present, in the fermentation process of organic fertilizer production, the organic matter is mainly fermented by the front and rear open fermentation tanks, and a turning device is installed on the fermentation tank to regularly turn and stir the fermenting organic materials to break up the materials. Make the material come into contact with the air, and prevent the material from being burned due to excessive fermentation temperature. [0003] However, in the fermentation tank, the turning device can only turn over and stir the materials accumulated on the upper layer, while the materials accumulated on the lower layer and corners of the fermentation tank body are short of oxygen due to the low probability of turning over, resulting in unsatisfactory fermentation effect . Moreover, no corresponding measures have b...
