Description

Technical Field

[0001] The present application relates to the technical field of mechanical dosing with flue gas recovery devices, and in particular to an integrated stirring and dosing device for slag removal of crude lead metal liquid. Background Art

[0002] Crude lead often contains 1-3% of various other metallic impurities, such as copper, zinc, cadmium, arsenic, antimony, and silver. The presence of these impurities significantly reduces the purity of the lead, affecting its physical and chemical properties. Some of these precious metals have comprehensive recycling value. The deslagging process of crude lead metal liquid can improve lead purity; the resulting removal of other metallic impurities can be used as a recycling material for minor metals. The resulting ultra-pure lead metal meets the requirements of downstream electrolytic lead smelting and use. Therefore, removing these impurities through the deslagging process is a key refining step in obtaining high-quality pure lead.

[0003] Chemical deslagging involves converting impurities into easily separable compounds or precipitates through chemical reactions. For example, during crude lead refining, different condensation temperatures are controlled and appropriate chemical reagents are added to initiate physical and chemical reactions with the impurities. The impurity metals, in the form of slag, are converted into other metallic compounds insoluble in the lead solution. The slag is then separated from the lead solution through filtration and salvage, enabling the comprehensive recovery of multiple metals.

[0004] In traditional small-scale crude lead pyrorefining, the addition of reagents to the crude lead molten metal is typically done manually. However, manual dosing is labor-intensive, time-consuming, and labor-intensive, leading to inaccurate dosing, occupational health risks, and incomplete metal impurity recovery. Utility Model Content

[0035] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0036] Example 1:

[0037] See also Figures 1 to 3 A stirring and dosing integrated device for removing slag from crude lead metal liquid, comprising a lead pot, the stirring and dosing integrated device for removing slag from crude lead metal liquid further comprising:

[0038] Stirring gas collecting hood 1;

[0039] A dosing bin 2 is provided above the stirring and gas collecting hood 1;

[0040] A stirrer 3 vertically mounted at the center of the lead pot;

[0041] Among them, a metering screw conveyor 4 is provided between the stirring and gas collecting hood 1 and the dosing bin 2. The feed end of the metering screw conveyor 4 is connected to the bottom of the dosing bin 2 through a pipe, and the discharge end is connected to the interior of the stirring and gas collecting hood 1 through a pipe.

[0042] Specifically, the lead pot is a reaction pool (not shown in the figure), which is located below the stirring and gas collecting hood 1. The dosing bin 2 is used to hold the reagent, and the bottom of the dosing bin 2 is connected to the feed end of the metering screw conveyor 4. The stirring and gas collecting hood 1 of the metering screw conveyor 4 can be fed with crude lead molten metal, and the discharge end is connected to the interior of the stirring and gas collecting hood 1. In this way, when unloading, the reagent first passes through the metering screw conveyor 4 and then enters the stirring and gas collecting hood 1. The metering feedback of the metering screw conveyor 4 is used to control the amount of reagent to be unloaded to avoid adding too much or too little reagent, thereby achieving precise dosing. After the reagent enters the crude lead molten metal in the lead pot and mixes, the mixed liquid is fully stirred by the agitator 3 to speed up the reaction rate of the crude lead molten metal and the reagent and improve the reaction effect. The waste residue formed by the reaction floats up, and after removing the waste residue, refined lead with higher purity can be obtained.

[0043] The present application utilizes the dosing bin 2 to contain medicines, controls the amount of medicine added through the metering feedback of the metering screw conveyor 4, and fully stirs the mixed liquid through the agitator 3. During the above process, the opening and closing of the dosing bin 2, the operation of the metering screw conveyor 4, and the action of the agitator 3 can all be automatically controlled, thereby realizing automatic dosing, reducing labor intensity, and saving time and effort.

[0044] Furthermore, manual dosing can lead to waste or insufficient impurity removal agents due to inaccurate metering. This device, through precise control of agent delivery, avoids waste and overuse of agents, effectively reducing production costs. Furthermore, through automatic dosing, this device reduces the risk of operators being exposed to unorganized fumes generated by agent reactions, ensuring operator safety and avoiding occupational health risks and incomplete recovery of small metals.

[0045] Example 2:

[0046] See also Figure 2 and Figure 3 Based on embodiment 1, optionally, the dosing bin 2 is in the shape of a funnel that is wide at the top and narrow at the bottom. A fixed cover 5 and a movable cover 6 are provided on the top of the dosing bin 2. The movable cover 6 is hinged to the fixed cover 5 and a handle 7 is provided on the movable cover 6.

[0047] Specifically, the dosing bin 2 is set to a funnel shape to facilitate material guiding. At the same time, the funnel-shaped structure can reduce the dead angle design and avoid the accumulation of medicines in the dead angle. The diameter of the circular cover formed by the fixed cover 5 and the movable cover 6 is larger than the top diameter of the dosing bin 2. The lower end face of the fixed cover 5 is fixedly connected to the upper end of the dosing bin 2. The straight edge of the fixed cover 5 is hinged to the straight edge of the movable cover 6. The lower end face of the movable cover 6 covers the dosing bin 2. By pulling the handle 7, the movable cover 6 can be pulled up or down to realize the opening and closing of the top of the dosing bin 2. In this way, it is convenient to observe the use of the medicine and prevent impurities from entering the dosing bin 2 to contaminate the medicine.

[0048] Optionally, the stirrer 3 comprises:

[0049] A motor 8 is mounted on the upper end surface of the stirring and collecting hood 1 , and an output shaft of the motor 8 extends into the stirring and collecting hood 1 and is connected to a rotating shaft 9 , on which a spiral blade 10 is sleeved.

[0050] Specifically, the output shaft of the motor 8 is connected to the rotating shaft 9 via a coupling, and the rotating shaft 9 is driven by the motor 8 to rotate, so that the spiral blades 10 can fully stir the solution.

[0051] Optionally, the output shaft of the motor 8 is rotationally connected to the stirring and gas collecting hood 1 through a bearing and a bearing seat, and the connection is mechanically sealed.

[0052] Specifically, the output shaft of motor 8 is rotatably connected to stirring hood 1 via a bearing and a bearing seat, which prevents significant friction between the motor and the wall of stirring hood 1, thereby ensuring effective transmission. A mechanical seal is provided at the connection to prevent leakage of solution from the hood, which could pollute the environment or waste lead resources.

[0053] It should be noted that the coordination and installation methods of the mechanical seal, bearing, bearing seat and output shaft belong to the existing technology and common knowledge, and will not be elaborated here.

[0055] See also Figure 1 and Figure 2 Based on the above embodiment, optionally, a flue gas pipe I 11 and a flue gas pipe II 12 are provided on both sides of the stirring and fume collecting hood 1 .

[0056] Specifically, smoke pipe I 11 and smoke pipe II 12 are provided to absorb smoke, thereby ensuring the safety of operators.

[0057] Optionally, an automatic control box 14 for controlling the flow rate is installed on the metering screw conveyor, and a gate valve 13 is installed at the bottom of the dosing bin 2.

[0058] Specifically, the gate valve 13 at the bottom of the dosing bin 2 is used to control the flow of the medicine.

[0059] Optionally, a support rod Ⅰ15 is provided on the outer wall of the dosing bin 2 , and the bottom of the support rod Ⅰ15 is fixed to the upper end surface of the stirring and gas collecting hood 1 .

[0060] Specifically, the upper end of the support rod 15 is fixedly connected to the outer wall of the dosing bin 2, and the lower end is fixedly connected to the upper end surface of the stirring gas collecting hood 1. The support rod 15 is used to support the dosing bin 2. Four groups of support rods 15 can be set to improve the stability of the support.

[0061] Optionally, a support rod II (not shown in the figure) is provided at the bottom of the stirring and gas collecting hood 1, and the support rod II covers the upper end of the pot surface of the lead pot.

[0062] Specifically, the support rod II is used to connect and support the stirring and gas collecting hood 1.

[0063] It should be noted that after hoisting and transferring the device, a separate slag remover can be used to remove the floating slag to obtain refined lead metal liquid. Slag removal is an existing equipment technology and will not be described in detail here.

[0064] It should be noted that the structures and / or installation methods not detailed in this application are known to those skilled in the art in combination with common knowledge and / or existing technologies, and are not the focus of disclosure in this application and will not be further elaborated here.
