NOVELTY - The upflow anaerobic reactor comprises a tank body (1) such as a sealed cylinder, a feeder (4, 5), a pressure protector (6), a gas outlet pipe (7), and a slag pipe (8). The tank body is internally provided with a breaking assembly and a heat energy conversion unit (3), and comprises a tank top, a cylinder, and a tank bottom. The feeder is placed on the top of the tank body, is provided with an automatic unloading pipeline memory device, and is composed of a body, a feeding port, a movable top cover, a material guide pipe, a body, a feeding opening, and a discharging hopper.    USE - The upflow anaerobic reactor is useful for processing livestock, rural household organic garbage and straw and other mixtures.    ADVANTAGE - The upflow anaerobic reactor is capable of simply, reliably and economically processing livestock, rural household organic garbage and other mixtures with large total solid concentration at uniform and constant temperature.    DETAILED DESCRIPTION - The upflow anaerobic reactor comprises a tank body (1) such as a sealed cylinder, a feeder (4, 5), a pressure protector (6), a gas outlet pipe (7), and a slag pipe (8). The tank body is internally provided with a breaking assembly and a heat energy conversion unit (3), and comprises a tank top, a cylinder, and a tank bottom. The feeder is placed on the top of the tank body, is provided with an automatic unloading pipeline memory device, and is composed of a body, a feeding port, a movable top cover, a material guide pipe, a body, a feeding opening, a discharging hopper, a baiting tube, a packing, and a discharging pipe. The tank top has a flat shape, semi-elliptical shape, semi-disk shape or semispherical shape. The stirring breaking assembly is composed of a power mechanism, a transmission shaft, a sealing piece, a shell breaking slag pushing device, and an impeller. The power mechanism is placed on the top of the tank body, and is connected with the top of the tank. The transmission shaft is connected with the power mechanism. The sealing piece is located on the transmission shaft through the top of the tank body. The shell breaking slag pushing device is connected with the transmission shaft, and is located on the inner material level. The impeller and the transmission shaft are connected. The heat energy conversion unit comprises a safe control box, a burner, a flame arrester, a gas pipe, a combustion heat exchange chamber, a smoke pipe, a water tank, and a circulating water pump. The combustion heat exchange chamber is located in the water tank. The smoke pipe is connected with the atmosphere. A wall of the combustion chamber is configured to heat the water tank gas liquid. The tank body of the circulating water pump form a closed system. The safety control box is connected with the flame combined action with the heat energy conversion unit. The movable top cover is located at the top of the tank. The material guide pipe and the pot body are present in the material cavity. The movable top cover is communicated with the atmosphere. The discharging hopper of liquid cavity and gas cavity of the tank body are communicated with each other. The discharging hopper and the material cavity are parallel. The packing is located on the box.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic cross-sectional view of an upflow anaerobic reactor.
