[0001] The utility model relates to the field of precious metal smelting, in particular to a quantitative acid adding device for precious metal smelting acidification. Background Art

[0002] Precious metals mainly refer to various metal elements such as gold, silver and platinum group metals. They are rare, have high financial value and can be purified. They are widely used to represent aristocratic status, investment assets, jewelry and various accessories.

[0003] When smelting precious metals, acid solutions are usually used to acidify the precious metals, so that the precious metal ores or concentrates are dissolved in the acid solutions, thereby separating the precious metals from the ores and further improving the purity of the precious metals.

[0004] However, when acidizing precious metals with acidic solutions, it is easy to fail to control the amount of acid added, thereby affecting the efficiency and stability of the precious metals during the acidification process. In addition, the flow rate of the acidic solution is difficult to control when adding acid. If the acid is added too quickly, the reaction rate may become faster and the solution may be unevenly mixed, which may cause an imbalance in the reaction state. Therefore, in view of the above problems, a quantitative acid adding device for precious metal smelting acidification is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a quantitative acid adding device for precious metal smelting acidification comprises a smelting tank 1; a pipe 11 is connected to the middle of the smelting tank 1; an acid storage tank 12 is connected to the end of the pipe 11; a metering pump 13 is fixedly connected to the end of the pipe 11; a control panel 14 is fixedly connected to the middle of the acid storage tank 12; a flow meter 15 is fixedly connected to the middle of the pipe 11; a valve 16 is connected to the middle of the pipe 11; a handle 17 is rotatably connected to the end of the valve 16; when working, the precious metal to be smelted is first placed inside the smelting tank 1, and then the amount of acid solution to be added is input on the control panel 14, and then the metering pump 13 is used to pump the acid solution inside the acid storage tank 12 into the smelting tank 1 through the pipe 11. When the amount pumped by the metering pump 13 reaches the control panel 14, the amount of acid solution added is input on the control panel 14. It will stop working after the threshold value is reached. When the acidic solution flows inside the pipeline 11, the flow meter 15 can detect the flow rate of the acidic solution. When the flow rate is too large, the handle 17 can be held and turned to control the opening and closing angle of the valve 16 to reduce the flow rate of the solution. This step can quantitatively control the acidic solution inside the smelting tank 1 through the cooperation of the metering pump 13 and the control panel 14, so as to improve the efficiency and stability of the acidification process, thereby improving the quality and output of the product, and at the same time reducing the waste of the acidic solution and reducing the production cost. The valve 16 and the handle 17 can control the flow rate of the solution, which can prevent the reaction rate from being accelerated due to excessive acid addition, thereby failing to ensure the equilibrium state of the reaction, and also causing uneven mixing of the solution.

[0024] like Figure 1 , Figure 2As shown, the top of the acid storage tank 12 is connected to a servo motor 3; the bottom of the servo motor 3 is rotatably connected to a second rotating shaft 31; a plurality of stirring paddles 32 are fixedly connected to the middle of the second rotating shaft 31; a fastening ring 33 is fixedly connected to the middle of the servo motor 3; a plurality of pillars 34 are fixedly connected to the middle of the fastening ring 33; when working, the servo motor 3 is first operated to drive the second rotating shaft 31 to rotate, and the second rotating shaft 31 will drive the stirring paddle 32 to rotate when rotating, so that the acid solution inside the acid storage tank 12 can be stirred. The fastening ring 33 and the support 34 can stabilize the position of the servo motor 3. In this step, the acid solution in the acid storage tank 12 is stirred so that the acid solutions can be well integrated with each other, thereby preventing the acid solution from being insufficiently integrated and affecting its smelting effect on precious metals, thereby causing the product quality inspection at the smelting site to fail to meet the standards. The mutual cooperation of the fastening ring 33 and the support 34 can prevent the servo motor 3 from shaking during operation, thereby affecting the stirring effect of the stirring paddle 32.

[0025] like Figure 3 , Figure 4 As shown, an exhaust fan 2 is fixedly connected to the top of the smelting tank 1; a cross support frame 21 is fixedly connected to the middle of the exhaust fan 2; a first rotating shaft 22 is rotatably connected to the middle of the cross support frame 21; a plurality of fan blades 23 are fixedly connected to the middle of the first rotating shaft 22; when working, the cross support frame 21 plays a role of supporting the first rotating shaft 22. When the exhaust fan 2 is needed to work, the first rotating shaft 22 can be rotated first. At this time, the fan blades 23 will rotate with the rotation of the first rotating shaft 22, so as to form a certain wind force, so that the exhaust fan 2 can be used to discharge the gas inside the smelting tank 1. In this step, a large amount of waste gas generated by the precious metals in the acidification process can be discharged to the outside through the action of the exhaust fan 2, so as to prevent the waste gas from causing harm to the environment and human health if it is not discharged in time.

[0026] like Figure 2 As shown, a plurality of heating rollers 4 are fixedly connected to the middle of the second rotating shaft 31; a plurality of heat sinks 41 are fixedly connected to the upper and lower sides of the heating rollers 4; when working, the heating rollers 4 generate heat, and the heat sinks 41 can better dissipate the heat generated by the heating rollers 4. In this step, the acid solution inside the acid storage tank 12 can be heated by the cooperation of the heating rollers 4 and the heat sinks 41, thereby increasing the solubility of the solute in the acid solution and making it easier to dissolve. At the same time, some volatile impurities can be volatilized from the acid solution by heating, thereby purifying the solution.

[0027] like Figure 1 , Figure 3As shown, a sound-absorbing shutter 5 is fixedly connected to the top of the smelting tank 1; a plurality of groups of window leaves 51 are fixedly connected to the middle of the sound-absorbing shutter 5; when working, the gas exhausted by the exhaust fan 2 will flow out to the outside through the sound-absorbing shutter 5. When the gas flows through the sound-absorbing shutter 5, it will generate friction and interference between the window leaves 51, thereby reducing the intensity of the noise. This step can reduce the noise intensity generated by the exhaust fan 2 when working and reduce noise pollution through the effect of the sound-absorbing shutter 5, thereby providing a quieter working environment for the staff.

[0028] like Figure 3 , Figure 4 As shown, the end of the exhaust fan 2 is fixedly connected with a valve plate 6; when the exhaust fan 2 is working, the gas exhausted by it will be discharged to the outside through the valve plate 6. When the gas flows through the valve plate 6, the valve plate 6 will be affected by the pressure brought by the gas and expand outward, so that the gas can be smoothly discharged to the outside. When the exhaust fan 2 is not working, the valve plate 6 will be in a closed state. This step can prevent the dust, impurities and other particulates from the outside from floating into the smelting tank 1 through the exhaust fan 2 when the exhaust fan 2 is not working, thereby causing pollution to the inside of the smelting tank 1 and affecting the precious metal smelting work.

[0029] like Figure 1 As shown, a transparent observation panel 7 is provided in the middle of the smelting tank 1; during operation, the smelting conditions of the precious metals inside the smelting tank 1 can be observed conveniently through the transparent observation panel 7. The opening of the transparent observation panel 7 can be used by workers to determine when to stop the smelting of the precious metals.

[0030] Working principle: during operation, the precious metal to be smelted is first placed inside the smelting tank 1, and then the amount of acid solution to be added is input on the control panel 14, and then the metering pump 13 is used to draw the acid solution inside the acid storage tank 12 into the smelting tank 1 through the pipeline 11. When the amount drawn by the metering pump 13 reaches the threshold of the control panel 14, it will stop working. When the acid solution flows inside the pipeline 11, the flow meter 15 can detect the flow rate of the acid solution. When the flow rate is too large, the handle 17 can be held and rotated to control the opening and closing angle of the valve 16 to reduce the flow rate of the solution. This step can quantitatively control the acid solution inside the smelting tank 1 through the cooperation of the metering pump 13 and the control panel 14, so as to improve the acidification The efficiency and stability of the process can be improved, thereby improving the quality and output of the product, while also reducing the waste of the acid solution and reducing the production cost. The valve 16 and the handle 17 can control the flow rate of the solution to prevent the acid from being added too quickly, which will cause the reaction rate to become faster, thereby failing to ensure the equilibrium state of the reaction, and also causing the solution to be mixed unevenly. When working, the servo motor 3 is first operated to drive the second rotating shaft 31 to rotate. When the second rotating shaft 31 rotates, it will drive the stirring paddle 32 to rotate, so that the acid solution inside the acid storage tank 12 can be stirred. The fastening ring 33 and the support 34 can stabilize the position of the servo motor 3. This step can stir the acid solution inside the acid storage tank 12, so that the acid solution can be mutually stirred. The two parts can be well fused together to prevent the acidic solution from affecting its smelting effect on the precious metals due to insufficient fusion, thereby causing the product quality inspection at the smelting site to fail to meet the standards. The cooperation between the fastening ring 33 and the support 34 can prevent the servo motor 3 from shaking during operation, thereby affecting the stirring effect of the stirring paddle 32. During operation, the cross support frame 21 supports the first rotating shaft 22. When the exhaust fan 2 is required to work, the first rotating shaft 22 can be rotated first. At this time, the fan blades 23 will rotate with the rotation of the first rotating shaft 22, thereby forming a certain wind force, so that the exhaust fan 2 can be used to discharge the gas inside the smelting tank 1. In this step, the precious metals can be discharged during the acidification process through the exhaust fan 2. A large amount of waste gas generated is discharged to the outside, so as to prevent the waste gas from causing harm to the environment and human health if it is not discharged in time. When working, the heating roller 4 will generate heat, and the heat dissipation wire 41 can better dissipate the heat generated by the heating roller 4. In this step, the acid solution inside the acid storage tank 12 can be heated by the cooperation of the heating roller 4 and the heat dissipation wire 41, so as to increase the solubility of the solute in the acid solution, making it easier to dissolve. At the same time, some volatile impurities can be volatilized from the acid solution by heating, so as to purify the solution. When working, the gas discharged by the exhaust fan 2 will flow out to the outside through the sound-absorbing shutter 5. When the gas flows through the sound-absorbing shutter 5, it will generate friction and interference between the window leaves 51.Thereby reducing the intensity of noise, this step can reduce the noise intensity and noise pollution generated by the exhaust fan 2 when it is working through the effect of the sound-absorbing shutter 5, so as to provide a quieter working environment for the staff. When working, when the exhaust fan 2 is working, the gas discharged by it will be discharged to the outside through the valve plate 6. When the gas flows through the valve plate 6, the valve plate 6 will be affected by the pressure brought by the gas and expand outward, so that the gas can be smoothly discharged to the outside. When the exhaust fan 2 is not working, the valve plate 6 will be in a closed state. This step can prevent the dust and impurities from the outside from floating into the smelting tank 1 through the exhaust fan 2 when the exhaust fan 2 is not working, thereby causing pollution to the inside of the smelting tank 1, so as to affect the smelting work of precious metals. When working, the smelting situation of precious metals inside the smelting tank 1 can be observed through the transparent observation plate 7. This step is to use the transparent observation plate 7 to allow workers to judge when to stop the smelting work of precious metals. ,
