Equipment system for adding drawing accelerator to karst fissures in subsidence area

Abstract

The invention discloses an equipment system for adding drawing accelerator to karst fissures in a subsidence area. The system comprises an accelerator chamber (1), a small liquid flowmeter (2), a control valve (3), a reducing tee (4), a rubber hose (5), an aerator (6), and an aerating pipe segment (7). The accelerator chamber (1) is supported by a steel frame (8). The rubber hose (5) is connected to the bottom of one end of the accelerator chamber (1). The small liquid flowmeter (2) is mounted on the rubber hose (5). The outlet end of the rubber hose (5) is connected with the reducing end of the reducing tee (4) through the control valve (3). The reducing tee (4) and the aerating pipe segment (7) are sequentially mounted on a drawing branch pipe. The aerator (6) is mounted at the bottom of the aerating pipe segment (7). The equipment system has the advantages such advantages that installation is convenient, operation is simple, the system is applicable to adding drawing accelerator to the karst fissures in the subsidence area, manufacturing cost is low, durability is high and application range is wide; the equipment system can meet the need for tailings accelerated setting in various types of drawing positions.

Description

technical field [0001] The invention relates to a device for adding accelerators, in particular to an equipment system for adding accelerators for tailings discharge, which is especially suitable for places where accelerators need to be added for tailings discharge in karst fissures in subsidence areas, so as to realize karstification in subsidence areas. Effective sealing of fissures. Background technique [0002] The tailings produced in our country are about 800-1000 million tons every year, most of which pass through the tailings storage yard. Due to the shortage of land resources, it is very difficult for mines to requisition land. Utilizing ground mining subsidence pits to discharge tailings is undoubtedly a shortcut that is both economical and saves valuable land resources. However, when there are underground mining activities at the bottom of the subsidence area, there are hidden dangers to the safety of underground workers, especially when there are subsidence areas...

AI Technical Summary

Problems solved by technology

[0005] (1) The conveying distance is too long, and when the amount of accelerator added is large, it is easy to block the pipe; when the amount of accelerator is reduced, it cannot meet the requirements of ore-drawing and quick-setting in cracks

[0006] (2) Due to the region where the cracks exist and the length, width and depth of the cracks are different, it is difficult to add accelerators in a targeted manner, resulting in waste of investment

[0007] (3) After adding the accelerator to the tailings conveying supervisor, it is necessary to add corresponding auxiliary equipment to ensure the successful tailings conveying, which also greatly increases the operating cost
