Abstract

This utility model discloses a high-efficiency black film anaerobic fermentation device for livestock farms, including a black film fermentation unit. The black film fermentation unit comprises a fermentation tank and an inner lining disposed within the fermentation tank for fermenting livestock farm waste. An automatic temperature control component includes an electric heating grid disposed between the fermentation tank and the inner lining. A temperature sensor is installed on the inner wall of the fermentation tank. A fixing box is installed on the outer wall of the fermentation tank, and an installation frame is connected inside the fixing box. A semiconductor cooling chip is disposed within the installation frame, and a cold air fan facing the cooling end of the semiconductor cooling chip is connected to the inner wall of the fixing box via a bracket. A cold air pipe is connected to the end of the fixing box away from the cold air fan, and the cold air pipe is connected to the fermentation tank. This utility model achieves temperature regulation within the fermentation tank through the automatic temperature control component, ensuring the fermentation temperature of the livestock farm waste within the fermentation tank is at the optimal temperature, thus improving the efficiency and effectiveness of black film anaerobic fermentation.
