Description

Technical Field

[0001] This utility model relates to the field of ore grinding technology, and more specifically, to a flocculant addition system. Background Technology

[0002] In the iron ore grinding and beneficiation process, the thickener is an important production equipment used for tailings dewatering. The tailings contain a large amount of fine particles, which cannot be settled in time by natural sedimentation. Flocculants need to be added to improve sedimentation efficiency and reduce the suspended solids content in the overflow circulating water. Therefore, ensuring the concentration of the thickener underflow and the quality of the circulating water has a great impact on production.

[0003] However, current thickeners suffer from low underflow concentration and turbid circulating water. Research has found that the main reason is that the fineness of the vanadium-titanium magnetite tailings processed by the thickener is greater than 86% (-325 mesh), requiring the addition of flocculants to improve the thickening efficiency. However, the existing flocculant delivery system has a high concentration and low flow rate, resulting in insufficient contact and interaction between the mineral particles in the slurry and the flocculant. This leads to low underflow concentration and poor circulating water quality, affecting the thickener's thickening efficiency and circulating water usage, significantly impacting production, and increasing operating costs and the probability of malfunctions.

[0004] In summary, how to provide a flocculant addition system is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0043] Please refer to Figure 1 In some embodiments, the pipeline assembly 3 also includes a liquid supply pipe 303, which connects the storage container 1 and the dilution container 2. The liquid supply pipe 303 is equipped with a liquid supply pump and is used to control the flow of flocculant to the storage container 1.

[0044] Optionally, in some embodiments, a valve is provided on the liquid supply pipe 303 to control the on / off state of the liquid supply pipe 303.

[0045] Optionally, in some embodiments, the connection between the liquid supply pipe 303 and the dilution container 2 is located at the top of the dilution container 2. Therefore, both the flocculant and the diluent enter at the top of the dilution container 2, which can greatly increase their mixing effect and further improve the dilution effect.

[0046] Optionally, in some embodiments, the diluent pipe and the supply pipe 303 are located on opposite sides of the dilution container 2, and their positions correspond to each other.

The buffer tank 4 and the distribution tank 5 are connected by a pipe. The dilution container 2 is connected to the distribution tank 5. The buffer tank 4 can not only buffer the slurry, but also receive the overflow flocculant solution, which helps to avoid the waste of flocculant.

[0053] In the above embodiments, the buffer tank 4 and the feed bucket 5 are structures used when adding tailings slurry. Through the above structures, the mineral particles in the slurry can fully contact and interact with the flocculant, thereby improving the settling efficiency.

[0054] In the above embodiments, the buffer tank 4 may adopt a box structure, and its height is lower than that of the overflow pipe 301, so as to receive the solution discharged from the overflow pipe 301.

The rotating shaft is equipped with several stirring blades. In other words, the rotating shaft is controlled by the motor to rotate, thereby controlling the rotation of several blades to increase the mixing efficiency and effect of the flocculant in the dilution container 2.

[0061] In the above embodiment, the stirring blades are installed at an inclined angle on the rotating shaft.

[0062] In the above embodiment, the stirring blade is provided with several through holes. When the dilution solution passes through the stirring blade, the through holes help to improve the mixing efficiency and effect of the flocculant in the dilution container 2.

[0063] A method of use for the above-mentioned flocculant addition system;

[0064] The flocculant in storage container 1 is transported to dilution container 2. A water pump can be used as the driving source, or a lift pump can be used. Storage container 1 is placed at the bottom to facilitate the replenishment of flocculant.

[0065] Diluent is added to dilution container 2 through the diluent pipeline box to dilute the flocculant concentration entering dilution container 2 to below 3%;

[0066] The diluted flocculant solution is conveyed through the addition pipe 304 to the addition head 6 which is uniformly set in the distribution tank 5, so that the flocculant solution is evenly dispersed in the distribution tank 5;

[0067] When the liquid level in dilution container 2 exceeds the preset value, the flocculant solution enters buffer tank 4 through overflow pipe 301.

[0068] Experimental conclusions: Based on the results of field use, the new flocculant addition system is more reasonable and scientific. Since its use, the flocculant concentration has decreased from 3‰ to 1‰, the flow rate has increased from 3m³ / h to 37.5m³ / h, flocculant consumption has decreased by 10%, the underflow concentration of the thickener and the quality of circulating water have been improved, and production costs and equipment failure rates have been reduced.

The pipeline assembly 3 is used to connect the storage container 1, the dilution container 2 and the thickening tank 7. The pipeline assembly 3 also includes a dilution liquid pipeline connected to the dilution container 2, which is used to add dilution solution to the dilution container 2.
