Description

Technical field:

[0001] The utility model belongs to the field of ore mining, and in particular relates to a mixing and stirring device for a slurry leaching tank. Background technology:

[0002] Leaching tank refers to a liquid-solid reactor that performs leaching operations at normal pressure and a temperature below 373 K. It is widely used in non-ferrous metal extraction and metallurgy. The selection of leaching tank mainly considers factors such as the characteristics, scale, and energy consumption of the leached material.

[0003] In the prior art, taking gold and silver mining as an example, after the slurry enters the leaching tank, in order to more accurately separate the gold and silver elements in the slurry, it is necessary to add chemical agents in the leaching tank to react chemically with the slurry to separate the gold and silver elements. Whether the added chemical agents are evenly mixed with the slurry is directly related to the sufficient and efficient extraction of the gold and silver elements. In order to make the chemical agents added in the leaching tank and the slurry evenly stirred and mixed, on the basis of the original stirring device, a plurality of air pipes are inserted into the leaching tank near the side wall, and air is injected into the leaching tank through the air pipes to generate bubbles. In actual operation, the bubbles generated by the air pipes are large in diameter and unevenly distributed, and the bubbles are not in sufficient contact with the slurry, resulting in a poor leaching effect. In addition, slurry precipitation occurs, resulting in a low leaching rate. Utility model content:

[0004] The utility model aims to provide a mixing and stirring device for a slurry leaching tank, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of poor slurry leaching effect.

Specific implementation method:

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0019] like Figures 1 to 5As shown, a slurry leaching tank mixing and stirring device comprises a leaching tank body 1, a frame frame 2 is installed on the top of the leaching tank body 1, a driving motor 3 is installed vertically downward on the frame frame 2, a stirring mechanism is connected to the driving shaft of the driving motor 3, a first circle tube 4 is arranged on the inner bottom surface of the leaching tank body 1, a second circle tube 5 is sleeved in the first circle tube 4, a third circle tube 6 is sleeved in the second circle tube 5, a plurality of exhaust holes 7 are evenly opened on the upper and lower surfaces of the first circle tube 4, the second circle tube 5 and the third circle tube 6, and the first circle tube 4 is provided with a plurality of exhaust holes 7. The coil tube 4 and the second coil tube 5 and the third coil tube 6 are connected through a branch tube 8. An air supply pipe 9 is installed on the side wall of the leaching tank body 1. The inner end of the air supply pipe 9 is connected to the first coil tube 4. A bubble nozzle 14 is installed on the exhaust hole 7. The bubble nozzle 14 is conical. The first coil tube 4, the second coil tube 5 and the third coil tube 6 are all coaxial with the leaching tank body 1. Support columns 15 are installed on the bottom walls of the first coil tube 4, the second coil tube 5 and the third coil tube 6. The bottom ends of the support columns 15 are fixedly connected to the inner bottom surface of the leaching tank body 1.

[0020] Specifically, the bubbles can be evenly distributed in the leaching tank through the first circle tube 4 , the second circle tube 5 and the third circle tube 6 .

[0021] In actual use, the air compressor first delivers compressed air to the first coil 4 through the air supply pipe 9, and the air in the first coil 4 is then delivered to the second coil 5 and the third coil 6 in turn through the branch pipe 8. At this time, the air in the first coil 4, the second coil 5 and the third coil 6 is evenly discharged through the exhaust hole 7. At this time, the conical bubble nozzle 14 can further compress the air to make its bubbles smaller and the flow speed of the bubbles faster, so that under the action of the stirring mechanism, the contact speed of the bubbles with the slurry in the leaching tank body becomes faster; at the same time, the bubble nozzle 14 installed on the lower surface of the first coil 4, the second coil 5 and the third coil 6 not only blows out the bubbles, but also quickly blows the bubbles to the inner bottom surface of the leaching tank body 1, so that the slurry precipitated on the inner bottom surface of the leaching tank body 1 can be brought up under the drive of the bubbles, and the slurry mixing becomes more uniform; the first coil 4, the second coil 5 and the third coil 5 are all coaxial with the leaching tank body 1, so that the bubbles generated by them can be evenly distributed in every corner of the leaching tank body 1.

[0022] like Figures 1 to 5 As shown, the stirring mechanism includes a rotating shaft 10, which is drivingly connected to the driving shaft of the driving motor 3, and a plurality of stirring rods 11 are horizontally and evenly installed on the outer circumference of the rotating shaft 10, and a plurality of stirring blades 12 are vertically and evenly installed on the outer circumference of the stirring rods 11, and a plurality of scattering holes 13 are evenly opened on the stirring blades 12.

[0023] Specifically, the bubbles can be further broken up into small bubbles through the breaking holes 13, thereby improving the mixing effect of the bubbles and the slurry.

[0024] During actual use, the driving motor 3 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the stirring rod 11 to rotate and evenly stir the slurry, chemicals and bubbles. At the same time, the breaking holes 13 opened on the stirring plate 12 can further break up the bubbles into smaller bubbles, so that the mixing effect with the slurry and chemicals is better.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
