Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A portion enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1-2 be a kind of gold mine cyanidation tailings governing system, including pneumatic trough 1 of sizing mixing, described in size mixing
Pneumatic trough 1 includes shell 2, arranges reaction tank 3 in described shell 2, structure between inwall and the sidewall of reaction tank 3 of described shell 2
Become cavity 11, described cavity 11 structure ringwise.
Described reaction tank 3 is internal is provided with crutcher 4, and the top of described shell 2 is provided with the charging connected with reaction tank 3
Mouth 12, the charging aperture 12 of described reaction tank 3 connects hot-water line and tailings conveyer device respectively.The charging aperture 12 of described reaction tank 3
It is provided with cover plate able to turn on or off, needs when not feeding to close cover plate, prevent the gas produced in reaction tank 3 the most recovered and directly escape
Dissipate.Described shell 2 lateral wall is provided with pH meter, and the probe of described pH meter stretches into the middle and lower part of reaction tank 3.Certainly, serosity is detected
PH can also be sampling after send analytical tool to test.PH meter be disposed to the pH conveniently detecting and controlling solution at a certain model
Enclose.Being uniformly provided with the through hole of Φ=2mm on described reaction tank 3, the distance between through hole and through hole is 2mm, described reaction tank 3
Side wall inner surfaces is fixedly installed one layer of waterproof ventilated membrane 8, fixes with riveting, the mode such as gluing.The HCN gas produced in reaction tank 3
