Stirring blade is provided on circumferential surface, the compression kettle lower surface is connected with sewage pipe, and Blowoff ball valve is provided in sewage pipe, institute
The outer peripheral surface lower part for stating compression kettle is provided with sludge pipe, and another nozzle of sludge pipe passes through screw pump and external sludge concentration tank
Connecting, the first ball valve is provided in sludge pipe, the compression kettle outer peripheral surface is arranged at intervals with several overflow pipes in the vertical direction,
And the second ball valve is provided on each overflow pipe, a nozzle phase of the several overflow pipes with adjusting water inlet pipe
It connects, and another nozzle for adjusting water inlet pipe connects with external conditioning tank.
Liquidometer is also vertically arranged on the compression kettle outer peripheral surface, the upper end of the liquidometer is fixed on compression kettle periphery
The top in face, lower end are fixed on the bottom of compression kettle outer peripheral surface.
The spacing of the adjacent overflow pipe is 50cm.
The stirring blade uses helical mixing blade.
Return pipe, another nozzle and sludge concentration tank of the return pipe are provided at the top of the compression kettle outer peripheral surface
Connect.
From the above, it can be seen that the utility model has following advantages:
1. the utility model solves the problems, such as that the sludge moisture content of existing sludge concentration tank is excessively high, by overflow pipe with stir
The layered structure that device forms supernatant and sludge is mixed, by the discharge of supernatant, to reduce sludge moisture content, is convenient for successive plates
The filters pressing of frame filter press.
2. the utility model observes device as supernatant using liquidometer, by the cooperation of liquidometer and overflow pipe, really
The separation for protecting supernatant and sludge, also ensures that the low sludge content of supernatant, can be used in subsequent processing.
