Device of material in vacuum clearance pressure filter

The utility model discloses a device of material in vacuum clearance pressure filter, including the pressure filter, install the filter cloth in the pressure filter, the device still includes the buffer device, and the buffer device is equipped with the atmospheric valve, and this atmospheric valve passes through the filter cloth in pipe connection to the pressure filter, the buffer device is connected with the vacuum pump. It adopts the vacuum suction ratio juris, earlier soak the running water for the residual material in the pressure filter, the agitating unit who opens the pressure filter simultaneously stirs, make residual material form mobile relatively good liquid thick liquid, then pass through the vacuum pump evacuation with the buffer device, again with in the atmospheric valve of buffer device and pipe connection to the pressure filter on the filter cloth, open the atmospheric valve, the liquid thick liquid that forms residual material aspirates in the buffer device, repeat above -mentioned operation 2 -3, residual material basically can clean up, its easy operation, safe and reliable, the operation environment is good, and intensity of labour is little, and materiel recovered is pollution -free.
