Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgy and relates to a CMC agent diluting device for mineral processing. Background Art

[0002] In the process of mineral flotation, CMC (carboxymethyl cellulose) changes the surface characteristics of mineral particles by adsorbing on the mineral surface or forming chemical bonds with the mineral surface, thereby affecting its flotation properties. It can also cause interaction between mineral particles and oxidants, increasing the oxidizing ability of oxidants on minerals, thereby effectively improving the flotation effect.

[0003] Although CMC can be dissolved in water at room temperature, this process takes a certain amount of time, and there will be agglomeration and incomplete dissolution. When the temperature is below 20°C, the dissolution rate of CMC is greatly reduced, and it is difficult to meet the large amount of CMC required in the mineral processing process. Moreover, when CMC is not fully dissolved, it is very easy to block the pipeline during long-distance transportation. In order to increase the dissolution rate, various equipment is usually required to heat the water source, and the use of heating devices consumes energy and increases costs. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is described in detail below with reference to the accompanying drawings:

[0016] like Figure 1As shown, a CMC reagent dilution device for mineral processing comprises a dilution tank 1 and a thickener 2. The top of the dilution tank 1 is connected to a water inlet pipe 3, on which a water inlet valve 4 is provided. Dilution water can be input into the dilution tank 1 through the water inlet pipe 3. The bottom of the dilution tank 1 is connected to a drain pipe 5, on which a drain valve 6 and a drain pump 16 are provided. The diluted CMC reagent can be discharged through the drain pipe 5 for subsequent use. A heating pipe 7 is coiled in the dilution tank 1. The top of the heating pipe 7 forms a water inlet 8 and the bottom of the heating pipe 7 forms a drain port 9. The dilution tank 1 can be heated by the heating pipe 7 so that the temperature in the dilution tank 1 reaches 35°C-30°C, so as to facilitate the dissolution of CMC. The thickener 2 is connected to an overflow pipe 10, which is connected to an intermediate tank 11. The clean water obtained after the overflow pipe 10 is precipitated can be discharged through the overflow pipe 10. The flow pipe 10 overflows into the middle tank 11. Since the thickener 2 is mainly used to process the mineral processing return water, the temperature of the clean water overflowed by the mineral processing return water after being processed by the thickener 2 is mostly around 35 degrees. The clean water processed by the thickener 2 can be used to heat the dilution tank 1, so that the temperature in the dilution tank 1 is maintained at 25-30°C to improve the dissolution effect of CMC. The middle tank 11 is connected to a water pipe 12, which passes through the side wall of the dilution tank 1 and is connected to the water inlet 8. A water pump 13 is provided on the water pipe 12. The drain port 9 is connected to a return pipe 14, which passes through the side wall of the dilution tank 1 and is connected to a water collecting tank 15. The water in the middle tank 11 is input into the heating pipe 7 for heat exchange to increase the temperature in the dilution tank 1, thereby improving the dissolution effect and efficiency of CMC.

[0017] A vertically arranged rotating shaft 17 is provided in the dilution tank 1, and the top end of the rotating shaft 17 passes through the top of the dilution tank 1. A motor 18 for driving the rotating shaft 17 to rotate is connected to the top end of the rotating shaft 17. A plurality of stirring rods 19 are provided on the rotating shaft 17, and the solution in the dilution tank 1 can be stirred by the stirring rods 19, so that CMC can be quickly dissolved in water. In addition, a liquid level meter 20 is provided on one side of the dilution tank 1, and a dosing port 21 for adding CMC into the dilution tank 1 is also provided on the top end of the dilution tank 1.

[0018] The usage of the utility model is as follows:

[0019] First, the thickener 2 is used to treat the slurry, and the 35℃-30℃ clean water obtained after treatment is input into the intermediate tank 11 through the overflow pipe 10 for collection. Then, the water inlet valve 4 is opened to input dilution water into the dilution tank 1 through the water inlet pipe 3, and the water level in the dilution tank 1 is observed through the liquid level machine 20. At the same time, CMC is added into the dilution tank 1 through the dosing port 21, and then the motor 18 is started to drive the rotating shaft 17 and the stirring rod 19 to stir. At the same time, the water delivery pump 13 is turned on to input the warm water in the intermediate tank 11 into the heating pipe 7 through the water delivery pipe 12 to heat the solution in the dilution tank 1. The liquid is heated to increase the solution temperature in the dilution tank 1 to 25-30°C, further improving the dissolution effect and efficiency of CMC. After the dilution is completed, the drain valve 6 and the drainage pump can be opened to discharge the CMC solution through the drain pipe 5 for subsequent use. The warm water is discharged to the water collection tank 15 through the return pipe after heat exchange through the heating pipe 7. In this process, the clean water treated by the thickener 2 can be continuously supplied to the intermediate tank 11 through the overflow pipe 10. The device uses the waste heat of the slurry to heat the dilution tank 1, realizes resource utilization, energy saving and environmental protection, and low cost.
