Description

Water supply device of filling system

Technical Field

The utility model relates to the technical field of mine tailing waste filling, in particular to a water supply device of a filling system.

Background

In the field of mine filling, water is generally required to be supplied to a filling station, and the supplied water source is used for preparing filling slurry, cleaning a filling pipeline and cleaning and dedusting the filling station. Some filling systems can adopt a mode of self-flowing water supply of a high-level water tank, so that the cost is lower and the water supply stability is good. For filling systems that cannot be self-supplied from a high-level sink, a pump is often required to pressurize the water supply. Conventional filling stations often employ submersible pumps to pressurize the water that is delivered to the filling station.

When the submersible pump works, the submersible pump needs to be buried in water, and the problems of cavitation, aging of a submersible cable and the like are often faced in the production process. When the submersible pump with serious cavitation is used for a certain time, the vanes are subject to cavitation and perforation, so that the pump body cannot be used. The aging of the submersible cable is also one of the problems that the submersible pump cannot be used and even electric leakage occurs, and the phenomenon can occur after a plurality of cables which are made of poor materials are wrapped outside the submersible pump and soaked for a period of time. The submersible pump is mostly below the water surface and will not be moved when maintenance is not required. When maintenance is required, it is more inconvenient to extract the submersible pump from the water than a ground pump type that can be directly maintained.

The prior art discloses a design method of a vertical sand silo annular overflow trough for replacing a high-level water pool, and the technology utilizes the height difference of the top of a vertical sand silo or a deep cone thickener to set the two annular overflow troughs into two grids. Wherein, the inner grid is used as a high-level water storage tank, and the outer grid is used as a water collecting and draining tank. When the tailings enter the vertical sand silo or the deep cone thickener for concentration, the overflow water enters the high-level water storage tank for storage through an overflow port on the top silo wall of the vertical sand silo or the deep cone thickener. When filling the production water, automatically supplying water to each water using place through a pipeline arranged at the bottom of the high-level water storage tank; and the redundant overflow water exceeding the capacity of the high-level water storage tank enters the water collecting and discharging tank through an overflow port at the top of the high-level water storage tank and enters a filling station drainage system through a pipeline hung along the outer wall of the vertical sand silo or the deep cone thickener. Although the technology does not need to arrange an additional high-level water pool water supply system, the structure is simpler. However, the water supply amount of the technology cannot meet the water consumption amount required by each link of filling production, and meanwhile, the overflow water still contains a large amount of minerals or fine sand and the like, so that the technology is not suitable for being used as a total water supply source of a filling station.
