The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a schematic diagram of the overall structure of the present utility model.
In the figure: concentrate buffer tank 1, first ore pulp conveyer pipe 2, automatically controlled valve 3, swirler 4, underflow mouth 401, overflow pipe 402, thickener 5, concentrated motor 6, concentrate storage tank 7, clarified liquid exit tube 8, concentrated ore pulp exit tube 9, second ore pulp conveyer pipe 10, send thick liquid pump 11, rabbling mechanism 12, agitator motor 13.
Detailed Description
As shown in fig. 1, a concentrate classification system for phosphoric acid production, which comprises a plurality of concentrate buffer tanks 1, wherein the discharge ports at the bottom of the concentrate buffer tanks 1 are connected to the feed inlet of a cyclone 4 through a first ore pulp conveying pipe 2 with branch pipelines, the underflow port 401 at the bottom of the cyclone 4 is connected to a concentrate storage tank 7, an overflow pipe 402 at the top of the cyclone 4 is connected to a thickener 5, the top of the thickener 5 is provided with a concentration motor 6, the bottom of the thickener 5 is provided with a clarified liquid outlet pipe 8 and a concentrated ore pulp outlet pipe 9, and the concentrated ore pulp outlet pipe 9 is also connected to the concentrate storage tank 7.
In the preferred scheme, the first ore pulp conveying pipe 2 and the branch pipes thereof are provided with electric control valves 3.
In a preferred scheme, one side of the concentrate storage tank 7 is provided with a second ore pulp conveying pipe 10, and the second ore pulp conveying pipe 10 is provided with a pulp conveying pump 11.
In the preferred solution, a stirring mechanism 12 is also arranged in the concentrate storage tank 7, and the stirring mechanism 12 is driven by a stirring motor 13 arranged at the top of the concentrate storage tank 7.
The utility model discloses a concentrate classification processing system for phosphoric acid production is when carrying out the concentrate ore pulp concentration operation before phosphoric acid production:
referring to fig. 1, by remotely controlling the opening and closing of the electric control valve 3, concentrate pulp in the concentrate buffer tank 1 is conveyed to the cyclone 4 by the first pulp conveying pipe 2, the pulp in the cyclone 4 forms a cyclone, coarse-particle ore flows downwards along the cyclone 4 and is discharged into the concentrate storage tank 7 by the bottom flow port 401, fine-particle pulp flows out along the overflow pipe 402 and enters the thickener 5 for concentration, the concentrated pulp returns into the concentrate storage tank 7 along the concentrate pulp outlet pipe 9, and the concentrate pulp in the concentrate storage tank 7 can be conveyed into the phosphoric acid production system by starting the pulp conveying pump 11.
In the above process, the mixing degree of the concentrated ore pulp input by the coarse-particle ore and the concentrated ore pulp outlet pipe 9 is insufficient, and the stirring motor 13 is started to drive the stirring mechanism 12 to stir in the above process, so that the mixing of the ore pulp is realized, and the uniformity of the ore pulp is ensured.
Taking the currently adopted flotation concentrate (concentration of 28%) as an example, the flotation concentrate needs to be washed and extracted after the concentration is raised to 63%.
After the scheme is adopted, the flotation 28% concentration concentrate is classified into a part of coarse particles with 63% concentration by the cyclone 4, the coarse particles directly flow into the concentrate storage tank 7 and are conveyed to the phosphoric acid system, and the fine particle concentrate overflows into the thickener 5 for sedimentation.
By adopting the scheme, the ore feeding amount of the thickener 5 can be successfully reduced, and three ball mills used for ore dressing can realize that only one thickener 5 is started, and each time one thickener 5 is reduced, one 15KW running motor can be stopped, one 45KW underflow pump, one flocculant adding device, a 15KW stirring system, one flocculant pump 5.5KW motor and the total of 80.5KW. The effects of increasing yield and saving energy are achieved to the maximum extent, and the manufacturing cost of concentrate can be effectively saved.
