The invention relates to a double cylinder continuous
sludge pumping device. The double cylinder continuous
sludge pumping device comprises a left main driving cylinder, a water tank, a left conveyingcylinder, a left connecting rod, a left
sludge pumping
piston, a left material tank, a conveying
pipe, a left feeding and discharging switching device, a right main driving cylinder, a right conveying cylinder, a right connecting rod, a right sludge pumping
piston, a right material tank, a right feeding and discharging switching device and a pre-installed packing device, wherein the left feedingand discharging switching device comprises a left swinging arm, a left discharging
piston, a left feeding piston, a left rotating shaft, a left driving device and a left sealing component; and the right feeding and discharging switching device and the left feeding and discharging switching device have the same structures and are arranged symmetrically. The double cylinder continuous sludge pumpingdevice has the benefits as follows: the structure is simple and reliable, the
noise is low during the pumping process, the direction change shock
impact is little, and due to the pumping of the double conveying cylinders, the working efficiency of the equipment is improved, and the unit
energy consumption is reduced; meanwhile, with the utilization of the device provided by the invention for pumping sludge, the outlet resistance of the pumping
system is reduced, the abrasion of the equipment during the pumping process is reduced, the reliability of the equipment is improved, and the service life of the equipment is prolonged.
