AI Technical Summary

Technical Problem

The drain pipe of the existing fermentation device is set at the bottom of the fermentation tank, which leads to high equipment costs and prone to failure. It is difficult to install during underground installation and poor applicability, so it cannot be applied to rural environments on a large scale.

Method used

An automatic liquid discharge fermentation device is designed. A water inlet pipe is installed at the bottom of the fermentation barrel and an overflow pipe is installed at the top. Clean water is injected through the water inlet pipe to make the fermentation liquid float up. The overflow pipe is automatically discharged from the fermentation liquid, realizing upward discharge, simplifying the liquid discharge structure and reducing installation difficulty.

Benefits of technology

It realizes automatic discharge of fermentation broth without manually opening the lid to salvage the fermentation broth, reducing odor pollution, simple and efficient liquid discharge structure, suitable for underground installation, strong applicability, and suitable for rural environments.

Abstract

The utility model discloses an automatic drainage fermentation device which comprises a fermentation barrel, a water inlet pipe and an overflow pipe, a fermentation cavity is arranged in the fermentation barrel, and the water inlet pipe is connected with the bottom of the fermentation cavity and used for injecting clear water into the fermentation cavity. The overflow pipe is connected with the top of the fermentation cavity and is used for discharging fermentation liquor at the top of the fermentation cavity through an overflow effect after clear water is injected into the bottom of the fermentation cavity. The automatic liquid discharge fermentation device provided by the utility model can realize automatic upward liquid discharge, does not need manual uncovering for fermentation liquid fishing, reduces odor pollution, is simple and efficient in liquid discharge structure, can supplement clear water for the fermentation cavity to realize next fermentation operation, can drive solid fermentation materials to float to the position of a barrel opening for convenient fishing, and is convenient to use. And compared with a downward liquid discharging mode, the solid fermentation materials cannot block the liquid discharging pipe under the gravity effect, a complex filtering structure does not need to be arranged, the fermentation barrel can be buried at any position, and waste is turned into wealth.
