Description

Technical Field

[0001] This application relates to the field of mineral processing equipment technology, and in particular to a flocculant preparation device. Background Technology

[0002] In flotation mineral processing, flocculants are often used in the roughing stage to deslim the minerals and improve their grade. During roughing, the flocculant needs to be added to the flotation equipment steadily, and there are requirements regarding the flocculant concentration range. To overcome the problem of the inability to continuously prepare existing flocculants, some preparation devices have been designed. For example, Chinese Patent Application No. 202020949163.5 discloses a preparation device for a mineral processing flocculant solution, including: a bottom plate, a preparation box, a rotating rod, a stirring rod, and a motor. Existing roughing flotation equipment often uses a parallel connection, meaning multiple flotation units are connected to a single flocculant storage tank simultaneously. The flocculant demand fluctuates significantly depending on the number of units operating. This preparation device addresses this issue in terms of flocculant preparation... The powdered flocculant and water are mixed in the container. The flocculant requires 5 to 10 minutes of stirring time to dissolve. During this period, if there is a peak demand for flocculant and the storage tank is low, it can easily lead to material shortage and machine shutdown, affecting the desliming operation of the flotation equipment. Secondly, the amount of flocculant used in desliming is small. The device directly mixes the flocculant in the container, and each time it is mixed, it needs to be weighed. There is a potential quality risk that workers may make calculation errors during the mixing process. Therefore, a flocculant mixing device is needed, which uses two mixing tanks to work together. The first mixing tank is used for the first mixing, and then the second mixing tank is used for dilution to obtain the required concentration, shortening the mixing time and reducing the risk of errors. Utility Model Content

[0003] To address the aforementioned issues, this application proposes a flocculant mixing device that utilizes two mixing tanks. The first mixing is performed in the first mixing tank, followed by dilution in the second mixing tank to obtain the desired concentration, thereby shortening the mixing time and reducing the risk of errors.

[0004] This application is achieved through the following technical solution:

[0005] This application discloses a flocculant preparation device, comprising: a first preparation tank, a second preparation tank, and a buffer tank. The first preparation tank is connected to the second preparation tank via a first metering pump. The lower part of the second preparation tank is connected to the buffer tank, and the buffer tank is connected to a coarse separation device via a second metering pump. The second preparation tank is divided into upper and lower layers by a partition. The partition has multiple through holes, and the lower end face of the partition has multiple conduits communicating with the through holes. Both the first and second preparation tanks are equipped with a stirrer, and the stirrer has stirring blades in both the upper and lower layers of the second preparation tank.

[0006] Furthermore, the buffer tank is provided with baffles, which are arranged alternately in the buffer tank.

[0007] Furthermore, the first mixing tank and the second mixing tank are connected to the clean water tank via the third metering pump and the fourth metering pump, respectively.

[0008] Furthermore, a heater is provided at the bottom of the first mixing tank.

[0009] Furthermore, the first mixing tank is provided with a feeding port at the top.

[0010] Furthermore, the length of the conduit is 3cm to 6cm, and the baffle is located at 1 / 2 to 2 / 3 of the height of the second mixing tank.

[0011] Furthermore, the second mixing tank is equipped with a level gauge.

[0012] The beneficial effects of this application are as follows: After a high concentration of flocculant solvent is prepared in the first mixing tank, it is then diluted in the second mixing tank to obtain the flocculant solvent of the required concentration. The time required for the dilution operation in the second mixing tank can be quickly completed to meet the flocculant demand when multiple coarse separation equipment are running simultaneously. The equipment uses a metering pump for mixing, which has high configuration accuracy, reduces the number of weighing operations by workers, and reduces the possibility of errors.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of the stated features.

[0018] like Figure 1 As shown, an embodiment of this utility model provides a flocculant preparation device, including: a first preparation tank 1, a second preparation tank 2, and a buffer tank 3. The first preparation tank 1 is connected to the second preparation tank 2 via a first metering pump 4. The lower part of the second preparation tank 2 is connected to the buffer tank 3. The buffer tank 3 is connected to a coarse separation device via a second metering pump 5. The second preparation tank 2 is divided into upper and lower layers by a partition 6. The partition 6 is provided with multiple through holes, and the lower end face of the partition 6 is provided with multiple conduits 7, which communicate with the through holes. Both the first preparation tank 1 and the second preparation tank 2 are provided with a stirrer 8, and the stirrer 8 is provided with stirring blades in both the upper and lower layers of the second preparation tank 2.

[0019] During preparation, clean water is injected into the first preparation tank 1 through the third metering pump 10 until it reaches 3 / 4 of its height. Based on the counting calculation of the third metering pump 10, flocculant is added to the first preparation tank 1 to prepare a 6% concentration flocculant concentrate. Then, the flocculant concentrate and clean water are injected into the second preparation tank 2 through the first metering pump 4 and the fourth metering pump 11 at a ratio of 1:19, and stirred by the agitator 8 to obtain a 0.3% flocculant solution. Injection is stopped after the second preparation tank 2 is full. When the coarse separation equipment requires flocculant, the flocculant solution is sent to the flocculant distribution device through the second metering pump 5 and distributed through the flocculant distribution device. In each coarsening device, after the liquid level in the second mixing tank 2 drops to the threshold, the first metering pump 4 and the fourth metering pump 11 are restarted. The flocculant concentrate and water enter the second mixing tank 2, are first stirred by the stirring blades in the upper layer, and then flow into the lower layer for further stirring. The flocculant solids have already dissolved into flocculant concentrate in the first mixing tank 1. After stirring, the flocculant concentrate and water can be quickly diluted to the required concentration. The buffer tank 3 extends the solution flow path, avoiding large concentration fluctuations in the flocculant solution during continuous mixing. Therefore, it is not necessary to configure a large-capacity second mixing tank 2 to meet the flocculant requirements of multiple coarsening devices.

[0020] The flocculant used is polyacrylamide. The third metering pump 10 injects 940L of clean water into the first mixing tank 1 each time. When preparing the solution, the worker only needs to weigh 60KG of flocculant and add it to the first mixing tank 1. The shelf life of high-concentration polyacrylamide solution is longer than that of low-concentration polyacrylamide solution, and the worker can meet the roughing of 150 to 250 tons of ore with one weighing, reducing the number of preparations and the probability of errors.

[0021] Preferably, the buffer tank 3 is provided with baffles 9, which are arranged alternately in the buffer tank 3. The baffles 9 extend the flow path of the flocculant solution on the one hand, and form multiple bends in the path in the buffer tank 3 on the other hand, so that the flocculant solutions mix with each other, ensuring that the concentration of the flocculant solution does not fluctuate significantly when the second mixing tank 2 is continuously prepared.

[0022] Specifically, the first mixing tank 1 and the second mixing tank 2 are connected to the clean water tank through the third metering pump 10 and the fourth metering pump 11, respectively. The third metering pump 10 and the fourth metering pump 11 calculate the amount of clean water, realize counting, and automatically dilute the second mixing tank 2, reducing the probability of error.

[0023] Specifically, the lower part of the first mixing tank 1 is equipped with a heater 12, which heats the clean water to 35°C to 40°C during preparation, thereby increasing the solubility of the flocculant and the dissolution rate.

[0024] In one specific embodiment, the first mixing tank 1 is provided with a feeding port 13 at the top, which facilitates workers to add flocculant to the first mixing tank 1.

[0025] In a preferred embodiment, the length of the conduit 7 is 3cm to 6cm, and the baffle 6 is located at 1 / 2 to 2 / 3 of the height of the second mixing tank 2. Through the obstruction of the baffle 6, the newly added water and concentrated flocculant first stay in the upper layer of the second mixing tank 2 to complete the first stirring, and then flow into the lower layer of the second mixing tank 2 to complete the second stirring, thereby achieving rapid dilution to obtain the flocculant of the required concentration.

[0026] In one specific embodiment, the second mixing tank 2 is equipped with a level gauge to obtain the liquid level information in the second mixing tank 2, so as to facilitate the start-up of the first metering pump 4 and the fourth metering pump 11.

[0027] Of course, this application may have many other implementation methods. Based on this implementation method, other implementation methods obtained by those skilled in the art without any creative effort are all within the scope of protection of this application.
