Novel submersible slag slurry pump

Abstract

The invention relates to the technical field of slag slurry pumps, in particular to a novel submersible slag slurry pump. The novel submersible slag slurry pump comprises the design of a booster anti-blocking type pump slurry device, when the liquid is pumped, a pump liquid main pipe of the pump slurry device is put into a tank, and when a motor rotates, a plurality of water supply blades, a booster turbine and a packing auger are driven to rotate together, so that the primary water suction pump liquid works when the plurality of water supply blades rotate; the booster turbine is arranged at the inlet end of an elbow and moves upwards through the action of the water supply blades, the slurry is thrown into a secondary pressurizing pipe through the elbow under the centrifugal action of thebooster turbine, and the effect of secondary pressurization is achieved; in the secondary pressurizing pipe, the packing auger rotates to push the slurry to move upwards and be discharged through a water outlet pipe, so that the effect of three-time pressurization is achieved; the multiple booster pump liquid makes the suction range of the slag slurry pump to increase; and a crushing anti-blockingrod is arranged at the inlet end of the bottom of the slag slurry pump, when the liquid is pumped, the crushing anti-blocking rod at the inlet end is driven to rotate together, and the effects of screening, crushing and anti-blocking are achieved.

Description

technical field [0001] The invention relates to the technical field of slurry pumps, in particular to a novel submersible slurry pump. Background technique [0002] Slurry pumps are generally referred to as slurry pumps that are suitable for transporting liquids (water) containing suspended solids. At present, it is one of the indispensable equipment in various processes of sewage treatment, mineral processing and coal preparation plants. Slurry pumps can be divided into single-stage / multi-stage, single-suction / double-suction, cantilever, horizontal / vertical, and horizontal split / vertical combination of pump casings according to different principles. [0003] Its basic structure is composed of impeller, pump casing, pump shaft, bearing and bracket. The power also includes motor, counter wheel or belt pulley coupling, etc. The wear-resistant parts also include liner sleeves, etc. The seals include shaft seals, The auxiliary impeller, etc., the support includes the bracket, ...

AI Technical Summary

Problems solved by technology

[0004] However, in order to prevent the clogging of the impeller at the bottom of the traditional slurry pump, it is necessary to install a protective cover at the bottom of the pump. When pumping liquid in pools and other environments, the slurry pump is easily blocked

[0005] Slurry pumps generally use a single impeller at the bottom to pump liquid, and the pumping pressure of the slurry pump is relatively low. When pumping liquid at a deeper position, the slurry pump cannot meet the working requirements.
