Overturning plate type continuous fermentation system

Abstract

The invention belongs to the technical field of agricultural machinery and relates to an overturning plate type continuous fermentation system. The system comprises a fermentation chamber, a feeding device, a discharging device, a gas storage device and a control device. The top of the fermentation chamber is provided with a feeding port connected with the feeding device, the upper portion of the fermentation chamber is provided with an exhaust port communicated with the gas storage device, the lower portion of the fermentation chamber is provided with a discharging port connected with the discharging device, and a liquid collection tank is arranged at the bottom of the fermentation chamber. Biogas slurry spraying devices communicated with the liquid collection tank are uniformly distributed at the inner top of the fermentation chamber, and overturning plate type fermentation devices are arranged in the fermentation chamber. The overturning plate type continuous fermentation system is capable of continuously performing uninterrupted fermentation, keeping suitable fermentation humidity and temperature in fermentation and enabling biogas generated by materials in fermentation to be easily discharged, and automatic control in operation of the whole fermentation system can be realized.

Description

technical field [0001] The invention relates to a continuous fermentation system and belongs to the technical field of agricultural machinery. Background technique [0002] At present, dry fermentation mostly adopts garage-type fermentation process or plug-flow dry fermentation process. However, the applicant found that: 1) the garage-type fermentation process cannot continuously feed in and out materials, and the materials are static in the fermentation warehouse and can only be fermented intermittently. The internal static of the fermentation tank leads to poor mass and heat transfer effect, acidification of some materials and unstable gas production; [0003] 2) The use of push-flow dry fermentation technology makes it difficult to discharge materials, and most of them do not have spraying facilities, their mass and heat transfer effects are poor, push-flow causes their local movement, and their overall material flow effect is poor.
