A Mine Tailings Paste Slurry Loop Test System and System Operation Method

Abstract

The invention discloses a metal tailing paste slurry ring pipe testing system and a system running method. The testing system comprises a slurry preparation system, a hopper, a pumping mechanism, a pipeline and a signal acquisition system. A discharging port of the slurry preparation system and the hopper communicate with each other and are used for conveying slurry and water into the hopper correspondingly. The pumping mechanism is used for pumping materials in the hopper into the pipeline. The pipeline comprises a bent pipe section and a straight pipe section, and a discharging port of the pipeline communicates with the hopper to form a circulating pipeline. The signal acquisition system comprises a lower computer, a pressure gauge, a temperature sensor, a concentration meter and a flowmeter, wherein the pressure gauge, the temperature sensor, the concentration meter and the flowmeter are mounted on the pipeline and are respectively connected with the lower computer. By means of themetal tailing paste slurry ring pipe testing system and the system running method, high-reliability, complete and sufficient data for later data analysis processing can be provided. Meanwhile, whether the pipeline is deposited or not and the location of deposition positions can be identified early in a running algorithm of the metal tailing paste slurry ring pipe testing system and the system running method for maintenance warning, the reliability of the data is ensured, and repetitive work is avoided.

Description

technical field [0001] The invention relates to a system for testing slurry resistance loss, and also relates to an operation method of the system. Background technique [0002] With the increase of mining depth, shallow resources are gradually exhausted, and resource mining gradually shifts to deep, and the proportion of filling mining in mining methods is increasing. The filling mining method can not only minimize the loss and dilution of ore, reduce the mine ground pressure, ensure the safety of mine production, but also deal with production waste rock and tailings in a timely manner, effectively reducing the impact on the ecology and protecting the surface from damage. [0003] Due to the complexity of the filling slurry, only through theoretical calculations, the frictional resistance loss in the pipeline transportation process has a large error, and the accuracy of the data cannot be guaranteed. Especially for high-concentration slurry, the frictional resistance loss i...

AI Technical Summary

Problems solved by technology

As for the test system, because it is not working in a complex and changeable working environment, the flow rate, concentration and particle size are all controllable. Only the deposition of solid particles on the pipe wall cannot be controlled by controlling the ratio of the slurry. Avoided

Moreover, the development process of deposition and scaling is very slow, and it is impossible to directly judge or predict where deposition occurs by simply and directly monitoring values ​​such as pressure and flow rate. Only after deposition has occurred for a long time and the pipeline has been significantly blocked to discover

Taking measures at this time can eliminate the blockage, but the data collected before is no longer valid, and the data collection and analysis work can only be carried out again, wasting time and energy
