Problems solved by technology

[0005] Its shortcoming is that the potential energy of the height difference of the slurry from the bottom surface to the bottom of the well is not utilized, but its energy is gradually consumed through the pressure relief box, resulting in energy waste; and the greater the height difference, the wasted energy more

Abstract

A deep well filling pressure release pipeline device comprises pipelines and pressure release tanks, the pressure release tanks are connected between the pipelines, one side of one pipeline is provided with an opening, and a potential energy conversion device is disposed at the opening. Slurry energy is collected and converted through the potential energy conversion device, slurry pressure of the pipelines is mitigated through the pressure release tanks, deep well filling slurry can be conveyed stably, the potential energy conversion device serves as a driving device of other deep well filling devices, potential energy of the slurry is effectively utilized, and linkage between the devices is increased. The invention also provides a deep well filling pressure release method comprising the steps that the slurry falls to the opening at the side of the pipeline and strikes baffle plates, and the baffle plates drive a main shaft to rotate; the slurry falls into the pressure release tank after striking the baffle plates; the main shaft transmits power to an auxiliary shaft and drives the auxiliary shaft to rotate; the auxiliary shaft drives stirring paddles to rotate; and the stirring paddles stir the slurry in the pressure release tank. According to the deep well filling pressure release method, the potential energy of the slurry serves as driving energy of the stirring shafts, the potential energy conversion device is linked with the stirring paddles, and integrity of the whole device is good.

Description

technical field [0001] The invention relates to the field of mine filling slurry transportation, in particular to a deep well filling pressure relief pipeline equipment and method. Background technique [0002] With the continuous exploitation of resources, mining needs to enter deep wells (below the surface of 800 meters), and the transportation of deep well filling slurry, the height difference from the surface to the bottom of the well is getting larger and larger, resulting in excessive pressure on the pipeline transportation of the slurry. However, the resistance of the pipeline is small, and there are unfavorable factors such as safety, pipeline wear, and operating costs in the pipeline transportation system. [0003] Most of the existing pipeline energy dissipation uses energy-dissipating orifice plates, but since the deep well filling slurry is mostly structured flow, that is, laminar flow, and the principle of energy-dissipating orifice plates is to increase the loc...
