Testing device for testing corrosion of rainwater to stockpiling body of tailing paste

Abstract

The invention discloses a testing device for testing the corrosion of rainwater to a stockpiling body of tailing paste, belonging to the field of stockpiling of surface tailing paste and mineral engineering. The testing device mainly comprises a testing bracket, a water supplying device, a control device, a spraying device, a stockpiling device, a measuring device and a liquid collecting device, wherein the water supplying device comprises a water pipe, a water storage groove and a water pump; the control device comprises a main control valve, an automatic timing switch, a flow meter, a pressure meter and a secondary control valve; the spraying device comprises a water feeding pipeline, spraying heads and a branch control valve; the stockpiling device comprises a paste stockpiling groove, a moving shaft at the bottom of a groove body, an angle adjusting shaft at the top of the groove body and limiting holes; the liquid collecting device comprises a liquid collecting groove and a liquid collecting barrel; the testing device comprises a TDR (Time-Delay Relay) probe, a data line and a data storage; the surface of an internal steel plate of the stockpiling groove body is provided with a diamond pattern, and the upper part of a side steel plate at the bottom of the stockpiling groove body is provided with a water discharging hole. The testing device disclosed by the invention has the advantages that the structure is simple, the paste stockpiling slope can be adjusted, the spraying amount and the spraying time can be adjusted, the slurry of the tailing is effectively collected, data is automatically acquired, further the model experimental study on the disaster formation and the evolution process of the stockpiling body of the tailing paste is further realized.

Description

[0001] Technical field [0002] The present invention involves a test device for testing tailings cream.Engineering field. Background technique [0003] After the ore mining of the mine is used through the minerals, the remaining solid waste is called the tailings, and it is generally discharged in the state of the ore.The tailings are generally stacked directly on the surface or used for underground filling.Generally, the tailings are preferred, but the undercut filling is restricted by various conditions, and many mines cannot be adopted.Therefore, it can only be built on the tailings of the tailings on the ground.As of now, there are more than 1,2600 tailings in my country, with a stack of about 8 billion tons of tail mines, and have grown at a rate of nearly 600 million tons per year.So many tail mines are stored on the surface not only occupy a large amount of arable land, but also more importantly to form major safety and environmental protection risks.Research from the Cla...
