Automatic control system for tailing pond blind well drainage

Abstract

The invention discloses an automatic control system for tailing pond blind well drainage. The automatic control system comprises a liquid level detection rod, the bottom end of the liquid level detection rod is fixedly connected with a fixed base through a bolt, the outer wall of the liquid level detection rod is provided with a first infiltration line and a second infiltration line, and the liquid level detection rod is sleeved with an annular magnetic levitation ball. According to the automatic control system for tailing pond blind well drainage, when the liquid level is lower than the lowerlimit set by a PLC control module, a control box controls a water pump to be closed, and when the annular magnetic levitation ball is lower than the first infiltration line, the water pump stops draining water and is always kept within the safety range, and no-load operation of the water pump when the liquid level is lower than the lower limit due to negligence is avoided; and the safety reliability and the drainage accuracy are guaranteed, the workload of workers is reduced, energy is saved, consumption is reduced, the PLC control module is adopted for control in a centralized mode, an alarmis given when a water line exceeds the highest limit set by the PLC control module, the water pump or the control box is prevented from being out of control or damaged, and the safety and stability coefficient of the tailings pond is greatly increased.

Description

technical field [0001] The invention relates to the technical field of automatic drainage control systems, in particular to an automatic drainage control system for blind wells of tailings ponds. Background technique [0002] The Gaowanqiu tailings pond of Shizhuyuan Company has been in use for more than 10 years, and the accumulated tailings are getting higher and higher. How to improve the stability of the dam body has aroused people's special attention. One of the most important issues, that is, the drainage and consolidation of the tailings dam is considered to be an effective way to improve the stability and safety of the dam, that is, the blind shaft drainage of the tailings dam. In the rainy season, the infiltration line rises rapidly with a large amount of rainwater, which greatly threatens the safety and stability of the tailings pond. The automatic drainage of the blind shaft of the tailings pond is mainly to reduce the infiltration line of the dam body and acceler...

AI Technical Summary

Problems solved by technology

Conventional blind well drainage pumps are manually opened. The disadvantage is that workers may not be able to open or close the pump in time due to negligence, causing the soaking line to exceed the limit value and causing danger to the dam, or the pump burns out due to long-term no-load operation.
