Constant-temperature anaerobic/aerobic fermentation tank for treating rotten vegetable leaves

Abstract

A constant-temperature anaerobic / aerobic fermentation tank for treating rotten vegetable leaves aims to effectively maintain the optimal fermentation temperature and realize switching of anaerobic / aerobic environments, a feed port is formed in the top of the fermentation tank body, a discharge port is formed in the bottom of the fermentation tank body, and a gate valve is mounted at the discharge port; a heat-insulating coil is mounted on the inner wall surface of the tank body; a water inlet and a water outlet are formed in the outer side of the fermentation tank body; an aeration pipeline is mounted at the lower end in the tank body, an aerator is mounted above the aeration pipeline, and an air inlet is formed in the outer side of the tank body; supporting legs are mounted at the bottom end of the tank body; a tank cover is mounted at the top end of the tank body, a sampling port is reserved in the tank cover, and a sealing gate is mounted at the sampling port; the tank cover is provided with a biogas outlet which is provided with a stop valve; a support is installed on the tank cover, a motor is fixed in the support and connected with a paddle column entering the tank body, and rotating paddles are installed on the surface of the paddle column. The device is compact in structure and simple to use, anaerobic and aerobic reactions can be carried out on the rotten vegetable leaves in a single tank, the occupied area of equipment can be effectively reduced, and the initial investment is reduced.

Description

technical field [0001] The invention relates to the field of anaerobic fermentation, in particular to a constant temperature anaerobic / aerobic fermentation technology. Background technique [0002] Fermentation refers to the process of using microorganisms to decompose organic matter, and the fermentation process needs to meet the needs of microorganisms for temperature, oxygen and other environments. At present, traditional fermentation equipment can be divided into aerobic type and anaerobic type. In the fermentation process, it is usually necessary to combine the two and meet the temperature and aerobic conditions of the two respectively, which not only occupies a large area of ​​​​the site to increase the initial investment of the equipment, and it is difficult to simultaneously Maintain optimal temperature for anaerobic and aerobic fermentation. [0003] In order to solve the above-mentioned problems, the Chinese patent with publication number CN207276616U discloses a ...

AI Technical Summary

Problems solved by technology

When working, this invention can connect the silica gel plug to the flame inoculation port to realize the conversion from aerobic to anaerobic environment, which can effectively reduce the equipment footprint and reduce the initial investment, but this device can only meet the oxygen environment requirements of fermenting microorganisms , the device itself cannot maintain the optimum temperature for fermentation

[0004] At present, there is no fermentation device both at home and abroad that can meet the optimum fermentation temperature and switch between anaerobic and aerobic environments
