Biological fermentation tank

Abstract

The utility model relates to the technical field of biological fermentation devices, provides a biological fermentation tank, and aims to solve the problem that solid-liquid fermentation materials are easily discharged out of the fermentation tank from an exhaust pipe by mistake in the conventional biological fermentation tank, and the biological fermentation tank comprises a fermentation tank body, and an exhaust port of the fermentation tank body is communicated with a tail gas bottle; the tail gas bottle comprises a bottle body and a bottle cap arranged at the top of the bottle body; a front exhaust pipe and a rear exhaust pipe are respectively arranged on the bottle cap in a penetrating manner, one end of the front exhaust pipe penetrates into the inner bottom of the bottle body, and one end, far away from the tail gas bottle, of the front exhaust pipe is communicated with the gas outlet of the fermentation tank body. According to the biological fermentation tank disclosed by the utility model, the tail gas bottle is arranged at the far end of the exhaust pipe, so that materials can be buffered, solid-liquid fermented materials are prevented from being taken out of the fermentation tank by gas, and the problem of blockage of the exhaust pipe can be reduced to a certain extent.
