Description

Dredge pump with cutting structure

Technical Field

The utility model relates to the technical field of sewage pumps, in particular to a sewage pump with a cutting structure.

Background

The sewage discharge vehicle is one of environmental sanitation devices, is mainly used for collecting, loading, unloading and transporting pollutants such as excrement, sewage, slurry and the like, and the existing sewage discharge vehicle mainly adopts a submersible pump and a vacuum pump for sewage discharge. Because sundries such as long fibers, paper, plastic films and the like are inevitably contained in the liquid pollutants, if a submersible pump is adopted for sewage disposal, the impeller is easily wound and blocked, so that the sewage disposal effect is influenced, and even the motor is overloaded and burnt in severe cases; if adopt the vacuum pump to carry out the blowdown, although can prevent to twine and block up, but its requirement to the material of liquid storage pot, the quality is very high, still test staff's operation control technical ability simultaneously, this is because the vacuum blowdown car owner relies on the vacuum pump to carry out the evacuation to the liquid storage pot earlier, reach certain vacuum in the liquid storage pot after, the blow off pipe carries out the blowdown again, consequently, in case the staff does not control well vacuum in the liquid storage pot and makes the vacuum too high, lead to the deformation damage of the liquid storage pot jar body very easily, can be if the vacuum is too low, the blow off pipe just can't normally blow off.

Chinese patent CN205064292U a dredge pump, it includes the pump body, pump body both ends are equipped with input port and delivery outlet respectively, be equipped with drive arrangement and pivot in the pump body, pivot one end is connected with drive arrangement's output, be equipped with the impeller in the pivot, the pivot other end is connected with the comminution device through the connector, pump body import department is equipped with bath device, bath device is through the external water supply system of water pipe, drive arrangement includes hydraulic motor, the hydraulic motor output is connected with pivot one end, hydraulic motor is through defeated external hydraulic oil supply system of oil pipe, the comminution device comprises a (mixing) shaft and a plurality of blade of setting at stirring epaxially.
