Self-stirring fermentation tank capable of automatically discharging pressure and used for bio-organic fertilizer

Abstract

The invention discloses a self-stirring fermentation tank capable of automatically discharging pressure and used for bio-organic fertilizers, the self-stirring fermentation tank comprises a shell, a piston cover plate, a pressure discharging air outlet, an air inlet and a discharging hole, the piston cover plate and an abutting block penetrate through the top surface of the shell, and a fixing spring is fixedly connected to the outer surface of the top end of the abutting block; and the tail end of the fixing spring is fixedly arranged at the top of the shell, the bottom end of the abutting block is connected with a telescopic rod, the telescopic rod is installed in the shell, and the top end of the telescopic rod is connected with a blocking plate. According to the self-stirring fermentation tank capable of automatically discharging the pressure and used for the bio-organic fertilizer, when the air pressure in the fermentation tank body is too large, the acting force of the air pressure is larger than that of a compression spring, so that the air pressure ejects open a blocking block, a pressure discharging air outlet hole is instantly opened, and the pressure is discharged through the pressure discharging air outlet hole; therefore, the effect of automatically discharging pressure is achieved, manual operation is not needed, and the tank is very convenient to use.

Description

technical field [0001] The invention relates to the technical field related to the production of bio-organic fertilizers, in particular to a self-stirring fermenter capable of automatic pressure relief for bio-organic fertilizers. Background technique [0002] Bio-organic fertilizer is a kind of fertilizer that is processed and produced by the residues of animals and plants. It is generally obtained by using animal manure or straw that is not needed by crops for harmless treatment, while the fermenter is It is a device that is often used in the production of bio-organic fertilizers. Through this device, the raw materials of bio-organic fertilizers can be stored for fermentation, so that the next step of production and processing can be carried out. However, the fermenter has Some disadvantages: [0003] First, for example, the application number and name are "CN201811358120.3 A kind of microbial organic fertilizer prepared by fermentation of sugar waste". The fermenter can ...

Problems solved by technology

[0006] The purpose of the present invention is to provide a self-stirring fermenter capable of automatic pressure relief for bio-organic fertilizers, to solve the problem of not having the effect of automatic pressure relief proposed by the above-mentioned background technology, and labor is relatively troublesome; The effect of gas, and the amount of air intake is uniform; it cannot be stirred automatically and needs electricity to drive, which is not enough for environmental protection and energy saving.
