Technical Field

The utility model relates to the field of cleaning of fine and soft silt and sludge, in particular to a double-impeller type submersible dredging pump.

Background

In the yellow river flood season water level increases in recent years, the flow increases, the quantity of wrapped silt is increased, the facility silt of a water taking system is caused many times, for rapidly clearing silted silt, a simple, convenient and reliable desilting pump is urgently needed, the desilting pump in the field is mainly used for clearing up hard blocks and clearing up silt by adding a stirring device or a crushing device, and the pump body is prevented from being blocked. Is not suitable for cleaning silt of buildings such as water intake system pipelines of the yellow river basin.

SUMMERY OF THE UTILITY MODEL

In order to realize simple, convenient and quick cleaning of silt and sediment in a water taking system of a yellow river basin, the utility model aims to provide the double-impeller type submersible dredging pump which can simply and effectively clean the silt and sediment blockage condition in the water taking system of the yellow river, and has the advantages of simple and light pump body structure, high working efficiency and low manufacturing cost.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model discloses a double-impeller submersible desilting pump which comprises a pump body, wherein the pump body comprises a double-output motor, a stirring pump is connected above the double-output motor, a suction port of the stirring pump is arranged above the stirring pump, the double-output motor drives the stirring pump to operate, high-pressure water in a volute high-pressure area of the stirring pump reaches a jet orifice at the lower end along a guide pipe arranged on the peripheral side to be sprayed out so as to scour and stir silt around the suction port of a sludge discharge pump, a sludge discharge pump connected with the double-output motor is arranged at the bottom of the pump body, and the sludge discharge pump is used for discharging silt around the suction port of the sludge discharge pump along a sludge discharge pipe through a sludge discharge port.

Furthermore, the periphery of the outer side corresponding to the high-pressure area of the volute of the mixing pump is uniformly connected with at least one flow guide pipe.

Furthermore, the lateral side that corresponds in the spiral case high pressure district of agitator pump all is connected with the root evenly the honeycomb duct is adjacent the contained angle of honeycomb duct is 90.

Furthermore, the lower end of the flow guide pipe is the jet orifice bent inwards by a certain angle.

Further, the jet orifice extends to the suction port of the sludge discharge pump and jets towards the lower part of the suction port of the sludge discharge pump.

Furthermore, small injection ports are spirally distributed on the peripheral side of each injection port, and filter screens are arranged at the inlet end and the outlet end of each pin injection port.

Compared with the prior art, the utility model has the following beneficial technical effects:

the device can effectively clean silted silt, and has the advantages of simple structure, high efficiency, small volume, low manufacturing cost, time and labor saving and high practicability.

Drawings

The utility model is further illustrated in the following description with reference to the drawings.

FIG. 1 is a front view of a dual impeller submersible pump according to the present invention;

description of reference numerals: 1. a stirring pump suction port; 2. a stirring pump; 3. a flow guide pipe; 4. a dual output motor; 5, a sludge discharge port; 6. an ejection port; 7, a suction port of a mud pump is arranged; 8. a sludge discharge pump.

Detailed Description

As shown in fig. 1, a bilobed wheel formula dive desilting pump, including the pump body, the pump body includes dual output motor 4, the top hookup of dual output motor 4 has stirring pump 2, and stirring pump suction 1 is in the top of stirring pump 2, the drive of dual output motor 4 stirring pump 2 operation work, the high pressure water of the spiral case high pressure district of stirring pump 2 reaches the jet 6 blowout of lower extreme in order to erode the mud around mud pump suction 7 along the honeycomb duct 3 that all sides set up and stirs, pump body bottom be provided with the dredge pump 8 of dual output motor 4 hookup, dredge pump 8 be used for with the mud thick liquid around mud pump suction 7 through the mud mouth 5 along the mud pipe drainage away.
