Small anaerobic/aerobatic integrated fermentation tank for research education

Abstract

The invention discloses a small anaerobic / aerobatic integrated fermentation tank for research education. A tank body and a tank cover fixedly connected in a sealed mode through fastening screws; a stirring motor and a controller are arranged on the tank cover; the tank cover is further provided with an exhaust port and an inner observation opening; the tank body is of an inner-and-outer layer cylinder structure; a heating layer is arranged on the outer wall of the inner layer of tank body; the interior of the inner layer of tank body is provided with a stirring rod connected with the stirring motor. The small anaerobic / aerobatic integrated fermentation tank for research education is further provided with a thermoelectric couple, an acidimeter, a methane concentration sensor and a pressure sensor which are connected with the controller through wires; the lower end of the tank body is provided with an air supply port and a reflux pump / liquid outlet; a reflux pipe is arranged outside the tank body and is connected with the reflux pump / liquid outlet; the reflux pipe is communicated into the inner layer of tank body; the reflux pump / liquid outlet presses percolate generated by fermentation back into the fermentation tank through the reflux pump or discharges the percolate generated by fermentation; bearings are arranged on the two sides outside the tank body and connected with a support; the tank body can rotate in a reciprocating mode by 0-180 degrees. The small anaerobic / aerobatic integrated fermentation tank for research education is compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a fermenter, in particular to a small anaerobic / aerobic integrated fermenter for scientific research and teaching, which is used for conducting anaerobic / aerobic fermentation experiments on solid domestic waste and biological waste. Background technique [0002] At present, the harmless treatment of solid domestic waste and biological waste is an effective waste disposal method. The fermentation process of aerobic / anaerobic bacteria is the key to the success or failure of aerobic / anaerobic fermentation. Therefore, to study the specific fermentation conditions of different anaerobic / aerobic bacteria requires a test equipment that is simple to operate and can automatically adjust and monitor various parameters in the fermentation process. [0003] Stainless steel fermentation tanks are generally suitable for teaching, scientific research or biological experiments in various scientific research institutes, colleges and universiti...

AI Technical Summary

Problems solved by technology

Existing fermentation tanks are divided into aerobic fermentation tanks and anaerobic fermentation tanks according to the growth and metabolism of microorganisms. One fermenter can be equipped with anaerobic / aerobic fermentation methods, which will greatly increase the utilization rate of equipment and reduce equipment procurement costs
