Application of Level Switch in Transfer of Mine Filling Material

Introduction:
In deep well mining, transferring mine filling material safely and efficiently is a challenge. Traditional methods using trucks or belts are inefficient. Pipeline transfer, powered by compressed air, offers a solution with an intelligent control system.

1. Applications of Level Switch:
The pipeline transportation system includes ground terminals, transit stations, and working stations. Accurate material level measurement is crucial throughout the process. Ground terminals store materials, transit stations manage automatic feeding, and working stations handle material proportioning and filling.

2. Technical Requirements for Level Switches:
Level switches must be reliable, easy to install, and maintenance-free. They should resist material buildup and false alarms. In underground environments, they must meet safety standards for explosion protection and use materials that prevent sparks.

3. Performance Comparison and Selection:
A comparison of level switches shows that double rod vibrating level switches are advantageous in mining conditions due to their maintenance-free nature, resistance to material buildup, and ease of installation. The Jiwei Tube-11, a domestic double rod vibrating level switch, was selected for its high sensitivity and reliability.

Case Study:
An environmental protection company in Beijing chose the Jiwei Tube-11 for a deep well project in Tianjin. The Tube-11 features a unique double tube design for high detection sensitivity and reliability, with a measurable medium density as low as 0.02g/cm³. It is certified for coal mine safety and has been successfully used since 2018.

Application of Level Switch in Transfer of Mine Filling Material-1

Application of Level Switch in Transfer of Mine Filling Material In deep well mining, how to transfer mine filling material and support materials in a safe, efficient and environmentally friendly way is a difficult question that mining enterprises are facing. The filling material is generally a fine powder which often solidifies quickly when it is stirred with water. There are two traditional methods for transferring filling materials. One is with mining trucks and another is with a transfer belt. Both methods have the problems of longer transportation time and too many links in the transfer path. In comparison, pipeline transfer uses compressed air as a power to fulfill one-stop automatic transportation of filling materials from ground to underground mine through an intelligent control system so that the problems with traditional methods will be effectively solved. Intelligent pipeline transportation systems mainly include ground terminal, transit station, working station, transfer pipeline and communication system. The stable operation of the system is relying on the accurate material level measurement. We need to figure out where the level switch will be applied in the filling material transfer process, what are the special requirements for the level switch in the underground environment, and how we can make the right choice for the level switch.

1. Applications of level switch in pipeline transportation of mine filling material. Ground terminal usually includes several vertical silos and transit silos that are ten meters or tens of meters high. It functions as a ground material storage terminal and control center. Transit station is located between the ground terminal and underground working station and should have a function of automatic feeding for empty silos and automatic stop when the silo is full. When the working station sends signal and demand filling materials, the transit station will automatically transfer the filling material...

Application of Level Switch in Transfer of Mine Filling Material-3

It is obvious to see from the above comparison that a double rod vibrating level switch, which is designed with nested internal and external vibrating rod, has more advantages under mining working conditions than other level switches: maintenance-free, strong resistance to material buildup, easy installation and safer to operate. After careful comparison between different brands and different types of level switches at home and abroad, an environmental protection engineering company in Beijing was convinced by the excellent quality of vibrating rod level switch from Jiwei and purchased Jiwei...
