NOVELTY - Methane generating tank for self slagging and screw type distributing comprises a cylinder main body tank (2), a feed inlet (1), a feed outlet (8), a screw distributing device (7), a streaming slope board (10) and a methane outlet. The feed inlet is arranged at one side of the bottom of main body tank. The lower end of the feed inlet and the upper end of the feed outlet arranged at the other side of the main body tank are in the same level. The screw distributing device is arranged in the center of the bottom of main body tank. The cross-section of the streaming slope board is V shaped.    USE - Used as a methane generating tank for self slagging and screw type distributing.    ADVANTAGE - The tank: provides continuous feeding and slagging, where the feeding is even and is 4 times more efficient than the conventional device in discharging the sediment.    DETAILED DESCRIPTION - Methane generating tank for self slagging and screw type distributing comprises a cylinder main body tank (2), a feed inlet (1), a feed outlet (8), a screw distributing device (7), a streaming slope board (10) and a methane outlet. The feed inlet is arranged at one side of the bottom of the main body tank. The lower end of the feed inlet and the upper end of the feed outlet arranged at the other side of the main body tank are arranged on the same level. The screw distributing device is arranged in the center of the bottom of the main body tank. The screw distributing device comprises a stirring axle and at least one layer of stirring paddle which are distributed in a reverse umbrella shape on the stirring axle for stirring the slurry. The streaming slope board is vertically arranged inside the bottom of the main body tank away from the feed inlet. The cross-section of the streaming slope board is V shaped. The methane outlet is arranged at the top of the main body tank.
