Compost fermentation equipment

Abstract

The invention discloses compost fermentation equipment, and relates to the field of compost fermentation, and the compost fermentation equipment is characterized by comprising a fermentation box, a separation ring wall is arranged in the fermentation box, a main shaft is rotatably connected to the middle of the separation ring wall, a motor connected with the main shaft is arranged in the separation ring wall, a fan located at the lower end of the separation ring wall is connected to the main shaft, an electric heating pipe is arranged at the upper end of the separation ring wall, a ventilation mechanism for supplementing oxygen is arranged in the fermentation box, a baffle mechanism for controlling the ventilation state of the ventilation mechanism is arranged at the upper end of the fermentation box, and a stirring mechanism located on the lower side of the separation ring wall and connected with the main shaft is arranged in the fermentation box. The invention has the technical effects that the running fan keeps air circulation in the fermentation box, in cooperation with the separation ring wall and the ventilation mechanism, air which does not contain oxygen and contains fermentation waste gas is discharged preferentially, the utilization rate of supplied oxygen is increased, the oxygen supply equipment operates intermittently, and the energy consumption of the equipment is reduced.

Description

technical field [0001] The invention relates to the field of compost fermentation, in particular to a compost fermentation equipment. Background technique [0002] The composting method to treat domestic waste refers to the method of decomposing, decomposing, and converting the organic matter in domestic waste into stable humus-like soil by virtue of the biochemical action of microorganisms under artificial control conditions. Exhaust air, decompose organic matter with aerobic bacteria, and the fermentation products are carbon dioxide, water and humus soil. [0003] The equipment in the prior art usually uses a simple stirring structure and cooperates with an oxygen supply device. The airflow generated by the oxygen supply device will carry the supplied oxygen to contact with domestic waste, and the stirring structure will stir the domestic waste again, so that the bottom rubbish can also be Aerobic fermentation takes place in contact with oxygen feed. [0004] However, th...

Problems solved by technology

[0004] However, the airflow inside this type of equipment is always in a state of circulation. After a brief contact with domestic waste, the supplied oxygen will be discharged from the equipment with the circulating airflow. The supplied oxygen cannot be fully utilized. For aerobic fermentation in an environment with sufficient oxygen, it is necessary to keep the oxygen supply equipment in a state of high-efficiency operation, which increases the energy consumption of the equipment
