NOVELTY - Hanging basket biogas digester comprises e.g. using bottom opening and utilizing hanging basket screening, letting insoluble ballast material falling into bottom of pool, using hanging basket replacement and scraping mud slurry product output principle. It comprises pool body, bearing beam, poly material cover, hanging basket, hanging frame, slide way, pulley, material delivery pipe, gas pipe, valve, thermostat regulator and material pit. It is further equipped with conveying pipe, cleaning device and filtering device. The dividing channel and ring formula.    USE - The device is useful in rural areas, urban areas and paper making for degrading various raw materials.    DETAILED DESCRIPTION - Hanging basket biogas digester comprises using bottom opening and utilizing hanging basket screening, letting insoluble ballast material falling into bottom of pool, using hanging basket replacement and scraping mud slurry product output principle. It comprises pool body, bearing beam, poly material cover, hanging basket, hanging frame, slide way, pulley, material delivery pipe, gas pipe, valve, thermostat regulator and material pit. It is further equipped with conveying pipe, cleaning device and filtering device. The dividing channel and ring formula. The pool body constructing objects of wall and bottom includes ring formula marsh gas pool in middle of table or column. The channel may extend to the ground level at least two terminal for setting sink falling pit. The ring formula has least one of setting sink falls. The pool is also set with support material pit and is connected with the upper, lower and supply mounted conveying pipe. The water level of two phase pit is kept equal. The bearing beam is column type, horizontal pool side, where the two ends are placed at two wall the pool body. The lifting support supply the poly material cover. The poly material cover is pouring bucket shape, which needs to turn on supply conveying pipe installation and hole installation and detecting hole and gas pipe. Taking the material cover, each correspond to two outer parts installed on the slide way. The basket bottom and peripheral wall of the opening and the bottom wall with obvious hole is good. The bottom outwards extends into supply mounting the hanging frame and hanging basket. The hanging frame is ladder type. The lower end has hole supply set on hanging basket cross arm. The upper end shaft and the pulley is connected with the slide way. The conveying pipe can divide third series, pump input machine, and pressure input machine. The falling type conveying pipe from inside and out has two layers. The inner layer is a hard pipe, where the top part is set with valve or sealing device. The part is provided with flange. The lower end is inclined or bent. The lower part through reserved hole is placed above the poly material cover. The vertical rod below the water surface and outside layer of the conveying pipe is corrugated and it encircles the feed delivering pipeline. The hard pipe and lower section of the port and top of the cover is identical sealing fixing material. The lower port of inside wall and outside wall of port below the hard pipe is identically sealed. The pressure type conveying tube is horizontal type attitude of the one end in the inner material cover. The other end through poly material pool body of the cover extends into hole in the material pit and one conveying pipe port is below the water line, where the winding system type network seed and poly material cover has at least one installation feeding pipe, the temperature regulating pipe along the angle and lower pool by pool bottom. The wall of outlet pool is connected along circulating device. The gas pipe through gas poly cover top surface is fixedly mounted. The conveyor from transport handle, spring, piston and the extension tube is equal. The handle is round cylindrical shape, where the lower end is set with flange, cylinder surrounding hard pipe and pin shaft diameter through center of the second vertical pipe. The flange and the spring of the transporting handle is fixedly connected. The spring surrounding the corrugated telescopic pipe, upper end port and the transporting handle and the corrugated telescopic pipe surrounding the hard pipe is identically connected and also surrounds pulley. The pulley is connected at the cross place of the transporting handle pin shaft. The piston is connected below. The piston middle hole and the corrugated pipe is identically interconnected, where it is set with outside power automatic close valve opening and the piston is fixedly connected with the spring.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the hanging basket biogas digester.
