Description

Technical Field

[0001] This utility model specifically relates to the field of electrolytic manganese impurity removal technology, and more specifically to an electrolytic manganese impurity removal device. Background Technology

[0002] Electrolytic manganese purification is a key step in improving the quality of electrolytic manganese. It involves using air to oxidize ferrous ions in the solution into ferric ions, and then adjusting the pH value to hydrolyze the ferric ions to form ferric hydroxide precipitate, which is then removed.

[0003] Chinese Patent Publication No. CN220276776U discloses an electrolytic manganese air iron removal device, relating to the field of electrolytic manganese iron removal technology. This utility model includes an electrolytic cell body, a lead screw fixedly connected to the output end of a lead screw motor, a movable block sleeved on the outer side of the end of the lead screw away from the lead screw motor, first connecting rods on both sides of the movable block, and a second stirring paddle rotatably connected to the end of the first connecting rod away from the movable block. A driven gear is meshed with one side of a driving gear, and a first stirring paddle is disposed on the outer side of the sleeve. This utility model, with its first and second stirring paddles, allows the lead screw to smoothly drive the movable block to move while the first stirring paddle rotates and stirs, thereby driving the second stirring paddle to stir up and down. The synergistic action of the first and second stirring mechanisms jointly assists in ensuring sufficient contact between the air and the electrolyte.

[0004] The aforementioned patent achieves aeration by supplying gas to the electrolytic manganese solution through an aeration pump and aeration pipe when removing impurities from electrolytic manganese. However, the aeration pipe in this technical solution is located at the bottom of the electrolytic cell. When the gas enters the electrolytic cell, it will cause the electrolytic manganese solution to tumble, making it impossible for the oxidized iron ions to hydrolyze and precipitate as ferric hydroxide. This makes it difficult to separate the electrolytic manganese solution from the ferric hydroxide. Utility Model Content

[0005] The purpose of this invention is to provide an electrolytic manganese impurity removal device that uses an aerator to aerate the electrolytic manganese solution. The aerator forms uniform and fine bubbles in the solution. Uniform aeration is crucial for the oxidation environment of the entire electrolyte, avoiding insufficient or excessive oxidation in certain areas. This ensures that ferrous ions are effectively oxidized to ferric ions in all parts of the solution, laying a good foundation for subsequent hydrolysis precipitation and iron removal. Furthermore, the aerator is suspended, and sufficient sedimentation space is reserved at the bottom of the stirring paddle to facilitate the precipitation of ferric hydroxide. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrolytic manganese impurity removal device includes a centrifugal blower, the outlet of which is connected to an aeration pipe; the other end of the aeration pipe is connected to an aerator; the aerator includes an outer shell, the middle of which has a shaft hole extending through it along its axial direction; and multiple exhaust pipes are arranged in a ring around the lower end of the outer shell.

[0008] The outer shell and the shaft hole are hollow, and the exhaust pipe is connected to the cavity inside the outer shell; the air inlet of the outer shell is located at the bottom of the outer shell.

[0009] The shaft hole is equipped with a bearing and is rotatably connected to the stirring shaft; the stirring shaft is also equipped with stirring blades.

[0010] As a further technical solution of this utility model, the stirring blades are arranged in an L-shape, and there are multiple stirring blades arranged in a ring array outside the stirring shaft.

[0011] As a further technical solution of this utility model, the upper end of the stirring shaft is connected to the output shaft of the stirring motor through a coupling, wherein the stirring motor is fixed on the top of the impurity removal tank.

[0012] As a further technical solution of this utility model, the impurity removal tank is fixed on the base frame, and a guardrail is fixed in a ring on the top of the impurity removal tank, and a ladder is welded on one side of the guardrail.

[0013] As a further technical solution of this utility model, a flow control valve and a flow sensor are connected in series on the aeration pipe.

[0014] As a further technical solution of this utility model, the bottom of the stirring blade and the aerator is not less than 20cm away from the bottom of the impurity removal tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, a centrifugal blower delivers air to the aerator through an aeration pipe. The gas enters the cavity inside the outer shell and is then discharged into the electrolytic manganese solution through an annular exhaust pipe at the bottom. The air oxidizes ferrous ions into ferric ions, and the air-suspended high-speed centrifugal blower can provide a stable and efficient air supply.

[0017] 2. This invention utilizes an air-suspended high-speed centrifugal blower to generate a stronger airflow, allowing oxygen in the air to come into more complete and rapid contact with ferrous ions in the solution. This helps accelerate the oxidation reaction, improve iron removal efficiency, and reduce the time required for the oxidation reaction.

[0018] 3. In this invention, when the stirring shaft drives the stirring blades to rotate, a negative pressure zone is created in the liquid, drawing air from the liquid surface to below the impeller. Simultaneously, the rotation of the stirring blades imparts strong kinetic energy to the drawn-in air-liquid mixture, causing the air to be sheared and broken into tiny bubbles within the liquid. These tiny bubbles are uniformly dispersed in the liquid and rise with the liquid flow, thereby increasing the contact area and contact time between the air and the liquid. During this process, oxygen diffuses from the bubbles into the liquid, achieving the purpose of aeration. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6In this embodiment of the present invention, an electrolytic manganese impurity removal device includes a centrifugal blower 1, the outlet end of which is connected to an aeration pipe 2; the other end of the aeration pipe 2 is connected to an aerator 5; the aerator 5 includes an outer shell 51, the middle of which is provided with a shaft hole 52 along its axial direction; and a plurality of exhaust pipes 53 are arranged in a ring around the lower end of the outer shell 51.

[0029] The outer shell 51 and the shaft hole 52 are hollow, and the exhaust pipe 53 is connected to the cavity inside the outer shell 51; the air inlet of the outer shell 51 is located at the bottom of the outer shell 51; the centrifugal blower 1 is an air-suspended high-speed centrifugal blower.

[0030] The shaft hole 52 is equipped with a bearing and is rotatably connected to the stirring shaft 6; the stirring shaft 6 is also equipped with stirring blades 7.

[0031] More specifically, the stirring blades 7 are L-shaped, and there are multiple stirring blades 7 arranged in a ring array outside the stirring shaft 6.

[0032] By adopting the above technical solution, when in use, the centrifugal blower 1 delivers air to the aerator 5 through the aeration pipe 2, and the gas enters the cavity inside the outer shell 51, and is then discharged into the electrolytic manganese solution through the bottom annular exhaust pipe 53; by using air to oxidize ferrous ions into ferric ions, the air-suspended high-speed centrifugal blower can provide a stable and efficient air supply.

[0033] In this embodiment, the upper end of the stirring shaft 6 is connected to the output shaft of the stirring motor 8 via a coupling, wherein the stirring motor 8 is fixed on the top of the impurity removal tank 12.

[0034] The stirring motor 8 drives the stirring shaft 6 to rotate, and the high-speed rotating stirring blades 7 give the air high kinetic energy and pressure, so that the air continuously reacts with the electrolytic manganese solution.

[0035] Compared to traditional methods, air-suspension high-speed centrifugal blowers can generate a stronger airflow, allowing oxygen in the air to come into more complete and rapid contact with ferrous ions in the solution. This helps accelerate the oxidation reaction, improve iron removal efficiency, and reduce the time required for the oxidation reaction.

[0036] When the stirring shaft 6 drives the stirring blades 7 to rotate, a negative pressure zone is created in the liquid, drawing air from the liquid surface to below the impeller. Simultaneously, the rotation of the stirring blades 7 imparts strong kinetic energy to the drawn-in air-liquid mixture, causing the air to be sheared and broken into tiny bubbles within the liquid. These tiny bubbles are evenly dispersed in the liquid and rise with the liquid's flow, thereby increasing the contact area and contact time between the air and the liquid. During this process, oxygen diffuses from the bubbles into the liquid, achieving the purpose of aeration.

[0037] In addition, the rotation of the stirring blades 7 also generates a strong stirring effect on the liquid, causing the liquid to circulate within the impurity removal tank, which promotes the mixing and transfer of substances in the liquid.

[0038] In this embodiment, the impurity removal tank 12 is fixed on the base frame 11, and a guardrail 9 is fixed in a ring on the top of the impurity removal tank 12, and a ladder 10 is welded on one side of the guardrail 9.

[0039] By adopting the above technical solution, when adding sulfiding agents such as sodium sulfide to the solution, one can climb up to the top of the impurity removal tank 12 via ladder 10 and add the agent into the tank through the dosing port;

[0040] A high-speed centrifugal blower with air suspension serves as a stirring power source. By adjusting the blower's operating parameters, a certain degree of agitation is created in the electrolytic manganese solution, promoting the dispersion of the sulfiding agent in the solution. This helps the sulfiding agent to fully mix and react with heavy metal ions (such as cobalt, nickel, and copper) to form sulfide precipitates. Moreover, this stirring effect is gentler than traditional stirring methods, reducing the possibility of unnecessary reactions between manganese ions and the sulfiding agent due to localized over-concentration.

[0041] In this embodiment, a flow control valve 3 and a flow sensor 4 are connected in series on the aeration pipe 2. The bottom of the stirring blade 7 and the aerator 5 is at least 20cm away from the bottom of the impurity removal tank 12.

[0042] After sulfide precipitate is formed, a high-speed centrifugal blower with air suspension can be used to assist in the precipitation separation process. The airflow intensity is appropriately controlled by the flow control valve 3 and the flow sensor 4 to create a flow field in the solution that is conducive to precipitate settling.

[0043] Heavier impurities settle more quickly and completely to the bottom of the impurity removal tank under the influence of gravity, thereby improving the efficiency of sedimentation and separation.

[0044] The working principle of this invention is as follows: During use, the centrifugal blower 1 delivers air through the aeration pipe 2 to the aerator 5. The gas enters the cavity inside the outer shell 51 and is then discharged into the electrolytic manganese solution through the annular exhaust pipe 53 at the bottom. The stirring motor 8 drives the stirring shaft 6 to rotate, and the high-speed rotating stirring blades 7 give the air high kinetic energy and pressure, allowing the air to continuously react with the electrolytic manganese solution. When the stirring shaft 6 drives the stirring blades 7 to rotate, a negative pressure zone is formed in the liquid, drawing air from the liquid surface to below the impeller. Simultaneously, the rotation of the stirring blades 7 imparts strong kinetic energy to the drawn-in air and liquid mixture, causing the air to be sheared and broken into tiny bubbles in the liquid. These tiny bubbles are evenly dispersed in the liquid and rise with the liquid flow, thereby increasing the contact area and contact time between the air and the liquid. In this process, oxygen diffuses from the bubbles into the liquid, achieving the purpose of aeration.

[0045] In addition, the rotation of the stirring blade 7 also generates a strong stirring effect on the liquid, causing the liquid to circulate in the impurity removal tank, which promotes the mixing and transfer of substances in the liquid.

[0046] After sulfide precipitate is formed, a high-speed centrifugal blower with air suspension can be used to assist in the precipitation separation process. The airflow intensity is appropriately controlled by the flow control valve 3 and the flow sensor 4 to create a flow field in the solution that is conducive to precipitate settling.

[0047] Heavier impurities settle more quickly and completely to the bottom of the impurity removal tank under the influence of gravity, thereby improving the efficiency of sedimentation and separation.
