Description

Technical Field

[0001] This utility model relates to the field of copper smelting technology, specifically to a uniform liquid addition device. Background Technology

[0002] Copper smelting processes generate waste liquids, which often contain valuable metals. Chemical reagents such as sodium hydrosulfide or liquid alkali are added to these waste liquids to induce precipitation reactions, followed by solid-liquid separation to recover the valuable metals. However, during the addition of these chemical reagents, the precipitates produced by the precipitation reaction often clog the pipe holes when the reagent addition tube is inserted into the waste liquid, affecting the normal addition of the reagents. Summary of the Invention

[0003] In response to the problems raised in the background art, this utility model provides a uniform liquid addition device to solve them, and the following will further elaborate on this utility model.

[0004] A uniform liquid addition device includes a reaction tank with an inlet on one side and an outlet at the bottom. A liquid addition device is also provided inside the reaction tank. The liquid addition device includes a circular pipe disposed outside the reaction tank, with a first addition pipe and a second addition pipe on both sides of the circular pipe. The first and second addition pipes extend into the reaction tank. A "Y"-shaped pipe is provided on the other side of the circular pipe, with the end of the "Y"-shaped pipe connected to the circular pipe. A reagent addition pump and a compressor are respectively connected to the end of the "Y"-shaped pipe.

[0005] Preferably, a stirrer is also provided inside the reaction tank.

[0006] Preferably, a waste gas collection port is also provided at the upper end of the reaction tank.

[0007] Preferably, a liquid level indicator is also provided on the side of the reaction tank.

[0008] Preferably, a plurality of liquid inlet holes are uniformly provided at the bottom ends of the first and second inlet tubes.

[0009] Preferably, a second regulating valve, a second flow meter, and a second pressure gauge are respectively installed on one of the "Y"-shaped pipelines; and a first regulating valve, a first flow meter, and a first pressure gauge are respectively installed on the other of the "Y"-shaped pipelines.

[0010] Preferably, the pressure displayed by the first pressure gauge is 1.1-1.2 times the pressure converted from the liquid level displayed by the liquid level indicator.

[0011] Preferably, the compressed air flow rate delivered by the second flow meter is 1-5 times that of the first flow meter.

[0012] Preferably, the pressure displayed by the second pressure gauge is 1.1 to 1.5 times that displayed by the first pressure gauge.

[0013] Beneficial effects: Compared with the prior art, this utility model uses compressed air to break the reagent into small particles of gas-liquid mixture, which are then added to the reaction tank through the liquid addition holes of the first and second addition pipes. The mixture reacts with the waste liquid to undergo precipitation reaction, and the waste gas is centrally treated and discharged from the tail gas collection port. This solves the problems of excessively high local concentration of reagent addition and precipitate entering the pipe holes and causing blockage. It also achieves full reaction, precipitation and separation of valuable metals, and requires less reagent. Attached Figure Description

[0017] Next, we will combine the appendix Figure 1-2 A specific embodiment of this utility model will be described in detail below.

[0018] A uniform liquid addition device includes a reaction tank 1, with an inlet 3 on one side and an outlet 16 at the bottom. A liquid addition device 4 is also provided inside the reaction tank 1. The liquid addition device 4 includes a circular pipe disposed outside the reaction tank 1, with a first inlet pipe 15 and a second inlet pipe 17 on both sides of the circular pipe. The first inlet pipe 15 and the second inlet pipe 17 extend into the reaction tank 1. A "Y"-shaped pipe is provided on the other side of the circular pipe, with the end of the "Y"-shaped pipe connected to the circular pipe. A reagent addition pump 13 and a compressor fan 12 are respectively connected to the end of the "Y"-shaped pipe.

[0019] A stirrer 2 is also provided inside the reaction tank 1 to stir the waste liquid, so that the reagent can fully contact the waste liquid;

[0020] The upper end of the reaction tank 1 is also provided with a waste gas collection port 5 for collecting the generated waste gas;

[0021] A liquid level display 14 is also provided on the side of the reaction tank 1 to observe the height of the waste liquid inside.

[0022] Multiple liquid inlet holes 18 are evenly provided at the bottom ends of the first inlet pipe 15 and the second inlet pipe 17. Before liquid inlet, the liquid inlet holes 18 are fully immersed in the waste liquid of the reaction tank 1.

[0023] A second regulating valve 7, a second flow meter 9, and a second pressure gauge 11 are respectively installed on one of the "Y"-shaped pipelines; a first regulating valve 6, a first flow meter 8, and a first pressure gauge 10 are respectively installed on the other of the "Y"-shaped pipelines.

[0024] It should be noted that:

[0025] The pressure displayed on the first pressure gauge 10 is 1.1 to 1.2 times the pressure converted from the liquid level displayed on the liquid level indicator 14;

[0026] The compressed air flow rate delivered by the second flow meter 9 is 1-5 times that of the first flow meter 8;

[0027] The pressure displayed by the second pressure gauge 11 is 1.1 to 1.5 times that displayed by the first pressure gauge 10;

[0028] Before adding the reagent, first close the outlet 16 and open the inlet 3. Observe and judge through the exhaust gas collection port 5 and the liquid level display 14 to ensure that the waste liquid completely submerges the agitator 2's impeller and the liquid inlet holes 18 of the first and second inlet pipes 15 and 17. Then, turn on the agitator 2, the compressor 12, and the reagent addition pump 13 respectively. According to the liquid level displayed on the liquid level display 14, adjust the first regulating valve 6 to ensure that the first flow meter 8 meets the process reagent addition flow requirements. The pressure displayed on the first pressure gauge 10 is 1.1-1.2 times the pressure converted from the liquid level displayed on the liquid level display 14. At the same time, adjust the second regulating valve 7. The compressed air flow rate delivered by the second flow meter 9 is 1-5 times that of the first flow meter 8 (chemical flow rate), and the pressure displayed by the second pressure gauge 11 is 1.1-1.5 times that of the first pressure gauge 10. Under the action of the compressed air, the chemical is broken into small particles of gas-liquid mixture, which are added to the reaction tank 1 through the liquid inlet 18 of the first inlet pipe 15 and the second inlet pipe 17, respectively, and react with the waste liquid to undergo a precipitation reaction. The waste gas is centrally treated and discharged from the tail gas collection port 5, thereby solving the problem of excessively high local concentration of chemical additives and blockage of pipe holes by precipitates, achieving full reaction and precipitation separation of valuable metals, and reducing the amount of chemical additives used.
