A high-efficiency method for adding water to a large sprinkler for open-pit mines

Abstract

An efficient water adding method for a large-scale sprinkler for open-pit mines, relating to an efficient water-adding method for a large-scale sprinkler for open-pit mines, including planning water addition points, determining the construction position of a high-level water collection tank, determining the position of a water outlet at the bottom of the high-level water collection tank to add water to the sprinkler truck There are five steps to determine the height difference between the points, determine the diameter of the conveying pipe between the water source point and the high water collection tank and between the high water collection tank and the water adding point, and determine the pumping speed of the water pump at the water source point. The water flow at the large-diameter water outlet can meet the needs of filling up the water in the shortest time, which is a good solution to the above-mentioned contradictions.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and relates to a water adding process, in particular to an efficient water adding method for a large sprinkler used in open-pit mines. Background technique [0002] Large-scale open-pit mines are seriously dusty, especially in stopes that use automobile transportation technology. The dust generated during the passing of production vehicles is very harmful to on-site equipment and operators. In order to meet the requirements of environmental protection, post hygiene, and equipment maintenance, mines need Sprinkle water continuously with sprinkler to reduce dust. [0003] Due to the wide working area of ​​the stope, the sprinkler needs to run efficiently to meet the requirements of dust prevention and environmental protection. The working process of the sprinkler is divided into two stages: adding water and sprinkling water. The measure to improve the working efficiency of the sprinkler is...

AI Technical Summary

Problems solved by technology

[0004] Traditional way of adding water (such as image 3 ): From the water source point 11 to the water filling point 10, a small-diameter water delivery pipe 1 is erected. The advantage of this scheme is to save investment costs and power costs. The disadvantage is that the small-diameter water delivery pipe 1 is too small. Insufficient, the sprinkler takes a long time to add water and the work efficiency is low;

[0005] The traditional way of adding water (such as Figure 4 ): From the water source point 11 to the water filling point 10, a large-diameter water delivery pipe 4 is erected to meet the needs of the sprinkler. The advantages of this scheme are that the water flow per unit time at the water outlet is relatively large, the time for adding water is short, and the sprinkler has a high working efficiency. The disadvantages are Investment cost and use cost are doubled compared with the former

[0006] The above two water adding methods cannot achieve the optimal effect of short water adding time and low water adding cost, and cannot be widely used in production
