NOVELTY - The utility model claims a constant temperature anaerobic marsh gas tank, relating to the technical field of marsh gas tank, comprising a marsh gas tank main body, the inner cavity of the marsh gas tank main body is provided with a stirring mechanism, one side of the marsh gas tank main body is provided with a heating mechanism, the stirring mechanism comprises an arc stirring rod. The utility model is composed of a heating rod and a drain pipe, the water valve is matched with the first water pump, the water in the inner cavity of the water tank is heated and pumped into the bottom of the inner cavity of the biogas tank, and the heat in the hot water is transferred to the excrement of the inner cavity of the biogas tank by the cooperation of the metal clapboard and the graphene heat conducting block, and the excrement is stirred by the stirring mechanism so that the excrement is uniformly heated, avoiding the air yield and temperature of the existing marsh gas tank are closely related, when using in winter, it will affect the marsh gas tank in the marsh gas amount of the problem, so as to convenient for heating the excrement in the marsh gas tank, improving the temperature of the marsh gas tank, at the same time, improving the marsh gas tank in winter.
