[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a multifunctional cyanide tailings harmless treatment device includes an oxidant tank 1, a slurry mixing tank 2 and a membrane filter press 3, and the membrane filter press 3 is connected to a mixing tank assembly 4.

[0020] In the present embodiment, specifically, the air outlet of the membrane filter press 3 is flange-connected with an air outlet pipe 7, and the multiple air inlets of the membrane filter press 3 are flange-connected with branch air inlet pipes 6, and the main air inlet pipe 5 is connected between the multiple branch air inlet pipes 6.

[0021] In this embodiment, combined with the Figure 2 and attached Figure 3 As shown, the mixing tank assembly 4 includes an upper tank body 41 and a lower tank body 42 which are integrally formed from top to bottom. A feed pipe 43 is integrally provided on both sides of the upper middle and rear sides of the upper tank body 41, and a discharge pipe 44 is integrally provided on the lower front side of the lower tank body 42. A transverse shaft 45 is connected to the internal transverse bearing of the upper tank body 41, and fan blades 46 are integrally provided on both ends of the transverse shaft 45, and a driving bevel gear 47 is fixedly installed in the middle of the transverse shaft 45. A longitudinal shaft 48 is arranged inside the lower tank body 42, and a lower end bearing of the longitudinal shaft 48 is installed in the middle part of the lower tank body 42, and a driven bevel gear 49 is fixedly installed on the upper end of the longitudinal shaft 48. The driven bevel gear 49 is meshedly connected to the lower part of the active bevel gear 47, and a bearing seat 50 is installed on the middle and upper bearing of the longitudinal shaft 48. The bearing seat 50 is fixedly connected to the lower tank body 42, and a stirring blade 51 is fixedly installed at the lower end of the longitudinal shaft 48. When the oxidant and the slurry enter the upper tank body 41 through the feed pipe 43 respectively, under the impact of the oxidant and the slurry, the fan blade 46 flips and drives the horizontal shaft 45 to rotate, so that the active bevel gear 47 drives the driven bevel gear 49 to rotate, and the driven bevel gear 49 drives the longitudinal shaft 48 and the stirring blade 51 to rotate, so as to preliminarily mix the oxidant and the slurry, so that the preliminary mixing of the oxidant and the slurry is more uniform.

[0022] In this embodiment, specifically, the discharge port of the oxidant tank 1 is connected to one of the feed pipes 43, the discharge port of the slurry mixing tank 2 is connected to the other feed pipe 43, and a valve is installed in the pipeline, and the discharge pipe 44 is connected to the feed port pipeline of the diaphragm filter press 3.

[0023] How it works

[0024] In the present invention, the oxidant in the oxidant tank 1 and the slurry in the slurry mixing tank 2 enter the mixing tank assembly 4 for preliminary mixing, and the mixed slurry enters the diaphragm filter press 3 for solid-liquid separation. The external gas is connected to the main air inlet pipe 5 and enters the diaphragm filter press 3 through the branch air inlet pipe 6. The gas disturbs the material in the diaphragm filter press 3, so that the oxidant and the slurry are mixed more fully.
