Feeding packing auger type submersible mud pump

Abstract

The invention relates to a feeding packing auger type submersible mud pump, and belongs to the technical field of electric pumps. The mud pump comprises a pump body with a water inlet and a water outlet, wherein a vertical type packing auger assembly driven by a motor is arranged in the pump body; the vertical type packing auger assembly comprises an impeller shaft and an impeller; the impeller rotates for throwing mud to the water outlet; the tail end of the impeller shaft is connected with a reamer shaft with a spiral blade; a drill bit is arranged at the tail end of the reamer shaft; the periphery of the spiral blade is provided with a guide pipeline; the end opening of the guide pipeline is used as the water inlet of the submersible pump; and the drill bit is exposed out of the end opening of the guide pipeline. The drill bit is used for drilling, pushing and lifting mud; the spiral blade not only can generate pushing effect, but also can generate stirring effect; a cutting-off tool bit and a crushing tool bit can be used for crushing large particles; the guide pipeline and the spiral blade jointly act, so that upward pushing force can be increased; and the submersible pump can increase discharge amount of mud, thereby avoiding large amount of surplus of mud, saving a manual clearing process, and achieving higher working efficiency and better discharge effect.

Description

technical field [0001] The invention belongs to the technical field of electric pumps, in particular to a feeding auger type submersible mud pump. Background technique [0002] With the development of science and technology, pumping applications in municipal engineering, environmental protection engineering, light industry, agricultural production, sewage treatment, etc. are increasing, and the sludge and mud generated are also increasing. Ordinary electric pumps can pump water up, but The silt and mud cannot be pumped away, and the effect of cleaning the silt is poor. The centrifugal action of the impeller in the pump has an upward suction force on the water, but because the silt has a certain viscosity, this suction is not enough to pump out the silt. Sludge, waterway dredging, septic tank pumping, breeding factory excrement and biogas tank waste residue cleaning, coal mine and non-ferrous metal tailings slurry pumping, power plant ash slurry cleaning cannot complete the s...

Problems solved by technology

[0002] With the development of science and technology, pumping applications in municipal engineering, environmental protection engineering, light industry, agricultural production, sewage treatment, etc. are increasing, and the sludge and mud generated are also increasing. Ordinary electric pumps can pump water up, but The silt and mud cannot be pumped away, and the effect of cleaning the silt is poor. The centrifugal action of the impeller in the pump has an upward suction force on the water, but because the silt has a certain viscosity, this suction is not enough to pump out the silt. Sludge, waterway dredging, septic tank pumping, breeding factory excrement and biogas tank waste residue cleaning, coal mine and non-ferrous metal tailings slurry pumping, power plant ash slurry cleaning cannot complete the sewage sludge extraction well, after the extraction is completed It is also necessary to manually clean up a large amount of remaining silt and mud, which consumes a lot of manpower and material resources, and the work efficiency is low. In the prior art, there is a technical solution for improving the electric pump, adding paddles under the impeller of the electric pump, but the paddles The leaf also only plays the role of stirring. It can mix the sediment in the water with water, and the mud-water ratio can reach 30% at most. The efficiency of mud pumping is still poor, that is, most of the pumping is water, and the extraction efficiency of mud lower
