NOVELTY - A winter non-consuming energy methane production device comprises feeding device (1), feeding mouth (2), stirrer (3), anaerobic reactor (4), discharge hole (5), discharge pond (6), solar vacuum heat collection tube (8), emergency electric heater, stent (10), and heat storage water tank (11). The feeding device is installed on the ground (7), the feeding mouth is welded above the reactor, and the lower end is stretched to inner liquid level below the reactor. The reactor is installed on stent, heat storage water tank is installed below the reactor, and stirrer is installed in reactor.    USE - As winter non-consuming energy methane production device for cold area (claimed).    ADVANTAGE - The winter non-consuming energy methane production device belongs to the fields of environmental protection and renewable energy sources. The reactor is designed to vacuum interlayer structure which can reduce heat loss. The lower part of the reactor is arranged with a hot storage water tank which has good energy storage effect. The solar energy hot collection tube is arranged in the bottom of the reactor which can directly transfer heat without pump loop, the energy conservation and warming effects are good. The emergency electric heater in the water tank can compensate and warm in cloudy days. The single blade vortex boosts the stirrer; the driven is handiness and can save power. The effect of stirring is good; the steel sire draw cord drags the overturn hopper to feed, and the feeding is convenient. The increasing and heat preserving effect of the total device is good, the operation is convenient without consuming additional energy, the factor of creating gas is high, which can guarantee the normal use in winter of cold area.    DETAILED DESCRIPTION - A winter non-consuming energy methane production device comprises a feeding device (1), feeding mouth (2), a stirrer (3), an anaerobic reactor (4), discharge hole (5), a discharge pond (6), a solar vacuum heat collection tube (8), an emergency electric heater, a stent (10), and heat storage water tank (11). The feeding device is installed on the ground (7), the feeding mouth is welded above the anaerobic reactor, and the lower end is stretched to the inner liquid level below the anaerobic reactor. The anaerobic reactor is installed on the stent, the heat storage water tank is installed below the anaerobic reactor, the stirrer is installed in the anaerobic reactor, and the discharge hole is welded in the tail of the tank of the anaerobic reactor. The discharge pond is located below the discharge hole, and the inner of the heat storage water tank is arranged with emergency electric heater (9). The heat storage water tank is connected with the solar vacuum heat collection tube which is below it, and above the solar vacuum heat collection tube, is covered with visors which can be rolled. The feeding device comprises a hopper, a steel wire draw cord, a rail, a powerful output the hopper is located at the bottom end of the rail next to the ground, the hopper is connected with the feeding hole by rail, and the steel wire draw cord is connected with the powerful output. The stirrer comprises a feature key axis, a manual operation rocker, a paddle, where the paddle is fixed on the feature key sleeve, the feature key sleeve is connected with the feature key axis by antifriction bearing, and the paddle is driven by manual operation rocker which is slipped along the axis when shifting. The tank shell of the anaerobic reactor is designed to inner container and outer container double-layer structure, and the middle of the two containers is vacuumized, and forming with interlayer, the inner surface of the inner container is pasted with anti thermal radiation coating, the outer container is prepared by non-metal material, the top of the anaerobic reactor is installed with a exit pipe, and the whole of anaerobic reactor and the heat storage water tank located inner of the tank external thermal insulation, where the tank external thermal insulation is prepared by heat-insulating material. The inner part of the heat storage water tank is arranged with thermodetector. The heat storage water tank is installed with water inlet and high-order exhaust port, and the high-order exhaust port is connected with the level instrument.
