Power generation mechanism filled with slurry

Abstract

The invention discloses a power generation mechanism filled with slurry. The power generation mechanism comprises a pipe body, a buffer mechanism and a power generation device, wherein the pipe body is provided with a feeding channel and a discharging channel, buffer parts which are communicated with each other are arranged between the feeding channel and the discharging channel, and the buffer parts are used for allowing the slurry to enter through the feeding channel and to be discharged from the discharging channel; the buffer mechanism is rotatably arranged in the buffer parts, so that the slurry enters and impacts the buffer mechanism to rotate; and the power generation device is in transmission connection with the buffer mechanism, and when the slurry impacts the buffer mechanism to rotate, the power generation device rotates together with the buffer mechanism to convert the slurry into electric energy.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a power generation mechanism for filling slurry. Background technique [0002] Metal and nonmetal underground mining mines generally have a well depth less than 500m, and when the well depth exceeds 700m, it is defined as an ultra-deep well. Underground mine filling refers to the use of tailings and cementitious materials according to a certain ratio to form a homogeneous two-phase flow filling slurry after being stirred evenly by a mixing tank, and then pumped to the underground goaf through a special filling hole for self-flow or pumping. After the slurry undergoes self-gelling reaction, it forms a filling body with certain compressive strength and self-supporting property, which is used to prevent surface subsidence and meet the follow-up mining work. [0003] Due to the deep depth of the existing ultra-deep mines, the vertical depth of the filling boreholes for subs...

AI Technical Summary

Problems solved by technology

When the filling slurry is transported in the special filling borehole for ultra-deep wells, an energy flow with high pressure head and high gravitational potential energy is formed, which forms a large pressure on the bottom of the filling borehole, and there is a hidden danger of pipe explosion and injury

And it will cause a large impact force on the contact point between the slurry and the vertical pipe. The long-term impact will damage the inner wall of the borehole. The hole is scrapped, and the gravitational potential energy of the slurry is wasted during the impact process, which is difficult to be effectively utilized
