Automation equipment and method for pouring microbial agent in continuous lifting mode to cure tailings

Abstract

The invention discloses automation equipment and a method for pouring a microbial agent in a continuous lifting mode to cure tailings. The automation equipment comprises a vehicle body, a drilling machine, a microbial agent mixing system, a high pressure air pump and a central control system, wherein the drilling machine, the microbial agent mixing system, the high pressure air pump and the central control system are all arranged on the vehicle body; a drill bit is arranged at the bottom of a drill stem of the drilling machine, the drill stem is a hollow pipe, a plurality of injection holes communicated with the outside are evenly drilled at one end, close to the drill bit, of the drill stem in the axial direction of the drill stem, the drill stem is sleeved with a protecting sleeve whichcan move up and down, the microbial agent mixing system and the high pressure air pump are both communicated with the hollow drill stem through pipelines, a microbial agent and high pressure air are respectively introduced into the drill stem and pumped into underground tailings through the drill stem, and the drilling machine, the microbial agent mixing system and the high-pressure air pump are all connected with the central control system and are controlled by the central control system. The automation equipment has the advantage of high automation degree; automation control on switch on-and-off of all valves, time setting, temperature control, pressure control, sensor data transmission and the like is achieved, and the pouring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tailings treatment, in particular to an automatic equipment and method for continuously lifting and injecting microbial agents to solidify tailings. Background technique [0002] Tailings refer to the part of the useful target components in the products of the sorting operation in the beneficiation that have a low content and cannot be used for production. In recent years, with the rapid development of dressing and smelting industry technology, people's demand for non-ferrous metals and products continues to rise, and the consumption of mineral resources is also increasing day by day. The grade of domestic mineral resources is low, complex and difficult to select, and a large amount of tailings will inevitably be produced in the process of industrial production. As of 2015, the existing stock of tailings in my country reached 14.6 billion tons. The stockpiling of tailings will lead to heavy gold pollutio...

Problems solved by technology

At present, the heavy metal pollution restoration methods of tailings mainly include physical method, chemical method and microbial method. The physical method is to change the existence state of heavy metal ions through precipitation and other methods, and the chemical method is to reduce the migration ability of heavy metal ions by adding some chemical substances. However, the cost of these methods of treatment is high, and the treatment effect is not ideal, and it is easy to cause damage to the soil ecological environment and cause secondary pollution.
