Abstract

The invention relates to an emulsion explosive conveying twin-screw pump system. The emulsion explosive conveying twin-screw pump system comprises an outboard bearing twin-screw pump, wherein the outboard bearing twin-screw pump is connected with an explosion-proof deceleration motor through a flexible coupler. The emulsion explosive conveying twin-screw pump system is characterized by also comprising a spiral propeller, wherein the spiral propeller is arranged in a propeller shell and connected with the propeller shell through a propeller bracket, the lower end of an outlet of the propeller shell is connected with the upper end of an inlet of the outboard bearing twin-screw pump, and the spiral propeller is driven by an explosion-proof motor connected at the other end of the propeller bracket. The emulsion explosive conveying twin-screw pump system has the advantages that by designing the two-motor driving type, the spiral propeller and the twin-screw pump are driven by different motors, the rotating directions, the rotating speeds and the power of the two motors are different, the motor of the propeller is low in power and rotating speed so as to be beneficial to material exhaust, and the driving motor of the twin-screw pump is high in power and rotating speed so as to be beneficial to material supercharging.

Description

technical field [0001] The patent belongs to the field of volumetric twin-screw pumps, in particular to a twin-screw pump system for conveying emulsion explosives. Background technique [0002] Twin-screw pump is a positive displacement pump, which has been widely used in various industrial fields such as petroleum, chemical industry, shipbuilding, and food. In the emulsion explosives industry, the main delivery pumps are single-screw pumps or ordinary twin-screw pumps. However, during use, the rubber stator of the single-screw pump is likely to be contaminated due to the abrasion of the rubber stator; the conventional twin-screw pump may cause insufficient suction capacity or a certain amount of air in the transported medium due to the high viscosity of the transported medium. , thus affecting the quality of emulsion explosives. Therefore, in the explosives industry, there is a need for a pump or pump system that can continuously and stably transport the medium, ensure th...
