As shown in fig. 1 to 8, the utility model discloses it is main including storing up mud pond 1, water catch bowl 2, sedimentation tank 3, extrusion pond 4, a stoving section of thick bamboo 5 and stoving mechanism, it is right to combine the figure below the utility model discloses carry out detailed description.

As shown in fig. 1 and 2, the sludge storage tank 1 is a rectangular parallelepiped structure with an open top, and is used for storing coal slurry. Be equipped with first outlet pipe 11, first outlet pipe 12, second outlet pipe 13, third outlet pipe 14 and fourth outlet pipe 15 that top-down set gradually on the lateral wall of storing up the mud pond, the coal slime is after storing up placing of mud pond through a period of time, and buggy, mud, coal granule can deposit in the bottom of storing up the mud pond and present the layering according to the quality size, and water is then arranged in the top of storing up the mud pond owing to lighter, and water discharges to the catch bowl through first outlet pipe in.

The water catch bowl with store up the adjacent setting in mud pit, sedimentation tank 3 is provided with a plurality ofly, is provided with four sedimentation tanks in this embodiment, and the sedimentation tank also is the open rectangular bodily form structure in top, and four sedimentation tanks are equidistant on a straight line and are arranged the setting. The water catch bowl sets up between sedimentation tank and storage mud pond, as shown in fig. 3, is equipped with second drain pipe 31 on the outer wall of sedimentation tank, and the upper strata is arranged in to the in-process water of sedimentation to the coal slime in the sedimentation tank, and the accessible second drain pipe discharges it to the water catch bowl in. First discharge pipe and first sedimentation tank intercommunication, second discharge pipe and second sedimentation tank intercommunication, third discharge pipe and third sedimentation tank intercommunication, fourth discharge pipe and fourth sedimentation tank intercommunication, the coal slime of different water contents like this, the coal slime of different compositions gets into in the different sedimentation tanks respectively.
