Description

Technical Field

[0001] The utility model specifically relates to the technical field of electrolytic manganese air iron removal, in particular to an electrolytic manganese air iron removal device. Background Art

[0002] In electrolytic manganese solution, iron is mainly in the form of ferrous ions (Fe 2+ ) exists in the form of. When air is passed into the electrolytic manganese solution, the oxygen in the air reacts with the ferrous ions to produce an oxidation reaction. Its chemical formula is: 4Fe 2+ +O2+4H + →4Fe 3+ +2H2O. In this process, ferrous ions are oxidized into ferric ions, creating conditions for the subsequent removal of iron.

[0003] Traditional electrolytic manganese usually uses stirring to aerate during iron removal. This simple stirring method of iron removal is relatively crude and has extremely low aeration efficiency. It cannot completely precipitate iron hydroxide, resulting in poor iron removal effect. Utility Model Content

[0004] The purpose of the present utility model is to provide an electrolytic manganese air deironing device, in which a permanent magnet variable frequency screw air compressor compresses the inhaled air through the rotation of the screw rotor. Its working principle is that two mutually meshing spiral rotors rotate in the casing, so that the air in the space between the rotor and the casing is continuously compressed, thereby generating high-pressure air. This air compressor has the characteristics of high efficiency and energy saving, and can adjust the speed and output air volume according to actual needs. In electrolytic manganese air deironing, it provides a stable air source for the deironing process. Permanent magnet variable frequency technology allows the air compressor to accurately adjust the air flow and pressure according to the requirements of the electrolytic manganese deironing process. In order to solve the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An electrolytic manganese air iron removal device includes a permanent magnet variable frequency screw air compressor, the air outlet of the permanent magnet variable frequency screw air compressor is connected to a compression tank via an air pipe; the compression tank is connected to an aeration tank via a delivery pipeline;

[0007] An aeration motor is fixed on the top of the aeration tank. The output shaft of the aeration motor passes through the interior of the aeration tank and is connected to an aeration stirring paddle through a coupling.

[0008] As a further technical solution of the present invention, the permanent magnet variable frequency screw air compressor is fixed on the base.

[0009] As a further technical solution of the present invention, a pressure gauge is threadedly connected above the compression tank; and a flow control valve and a flow sensor are serially connected to the delivery pipeline.

[0011] As a further technical solution of the present invention, a guardrail is fixed on the top of the aeration tank. The guardrail is arranged in a C shape, and a ladder is provided at the opening of the guardrail; the lower end of the ladder is welded to the base frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this utility model, a permanent magnet variable frequency screw air compressor compresses gas and delivers it to a compression tank for storage. The compression tank delivers the compressed air to an aeration tank through a delivery pipe. The aeration motor drives the aeration stirring paddle to rotate and stir the electrolytic manganese solution, thereby increasing the contact area between the electrolytic manganese solution and oxygen in the air, allowing oxygen to fully contact ferrous ions. This allows the electrolytic manganese solution to produce uniform and fine bubbles, promoting the oxidation of ferrous ions and creating favorable conditions for the oxidation reaction, thereby improving iron removal efficiency.

[0015] 3. In the present invention, the oxidized iron ions are hydrolyzed at a certain pH value to form iron hydroxide precipitates. The continuous supply of air helps to maintain the redox state and pH value in the electrolytic manganese solution relatively stable (through the balancing effect of consuming hydrogen ions in the oxidation reaction), which is beneficial to the complete formation of the iron hydroxide precipitate and the subsequent precipitation and separation operation, so that iron can be more effectively removed from the electrolytic manganese solution.

DETAILED DESCRIPTION

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

[0023] See also Figure 1-5 In an embodiment of the utility model, an electrolytic manganese air iron removal device includes a permanent magnet variable frequency screw air compressor 1, the air outlet end of the permanent magnet variable frequency screw air compressor 1 is connected to a compression tank 4 through an air delivery pipe 3; the compression tank 4 is connected to an aeration tank 9 through a delivery pipe 6; the permanent magnet variable frequency screw air compressor 1 is fixed on a base 2.

[0024] As a further illustration of this embodiment, permanent magnet frequency conversion technology enables the air compressor to accurately adjust the air flow and pressure according to the requirements of the electrolytic manganese deironing process. Appropriate air flow is one of the key factors to ensure the full oxidation of ferrous ions. By controlling the motor speed through the frequency converter, the air compressor can output air of different flow rates. For example, in the early stages of deironing, a large flow of air may be required to quickly oxidize a large amount of ferrous ions; as the reaction proceeds, the air flow can be appropriately reduced. At the same time, the appropriate pressure can ensure that the air can be fully dispersed when it is passed into the electrolytic manganese solution, so that oxygen and ferrous ions are effectively in contact. Generally speaking, the air pressure output by the air compressor must be able to overcome the static pressure and pipeline resistance of the electrolytic manganese solution to ensure that the air can be smoothly passed into the electrolytic manganese solution.

[0025] Furthermore, an aeration motor 13 is fixed to the top of the aeration tank 9 , and the output shaft of the aeration motor 13 passes through the interior of the aeration tank 9 and is connected to an aeration stirring paddle 14 via a coupling.

[0026] By adopting the above technical solution, the permanent magnet variable frequency screw air compressor 1 compresses the gas and then transports it to the compression tank 4 for storage. The compression tank 4 transports the compressed air to the aeration tank 9 through the delivery pipe 6. The aeration motor 13 drives the aeration stirring paddle 14 to rotate to stir the electrolytic manganese solution, thereby increasing the contact area between the electrolytic manganese solution and oxygen in the air, allowing oxygen to fully contact ferrous ions, and causing the electrolytic manganese solution to produce uniform and fine bubbles, promoting the oxidation of ferrous ions, creating good conditions for the oxidation reaction, and thus improving the iron removal efficiency.

[0027] The oxidized iron ions are hydrolyzed at a certain pH value to form iron hydroxide precipitates. The continuous supply of air helps to maintain the redox state and pH value in the electrolytic manganese solution relatively stable (through the balancing effect of consuming hydrogen ions in the oxidation reaction), which is beneficial to the complete formation of the iron hydroxide precipitate and the subsequent precipitation and separation operation, so that iron can be more effectively removed from the electrolytic manganese solution.

[0028] In this embodiment, a pressure gauge 5 is threadedly connected to the top of the compression tank 4 ; and a flow control valve 7 and a flow sensor 8 are serially connected to the delivery pipeline 6 .

[0029] By adopting the above technical solution, the arrangement of the compression tank 4 and the pressure gauge 5 provides a stable gas source for the aeration of the electrolytic manganese solution; the flow control valve 7 and the flow sensor 8 can monitor the flow of the compressed gas and control the opening and closing;

[0030] The output compressed air pressure must be able to overcome the static pressure of the electrolytic manganese solution and the pipeline resistance, etc., to ensure that the air flows smoothly into the electrolytic manganese solution; the flow rate of the compressed gas can be monitored by the flow sensor 8, and the flow control valve 7 ensures the control of the flow rate.

[0031] The compressed air flow rate is generally determined by the volume of the electrolytic manganese solution, the ferrous ion concentration, and the size of the aeration tank 9. Typically, 0.5-2 cubic meters of air are introduced per cubic meter of solution per minute. The aeration time is adjusted based on the initial ferrous ion concentration and the iron removal requirements. It is generally necessary to continue aeration for several hours, and the appropriate aeration duration is determined by monitoring the changes in the ferrous ion concentration in the solution.

[0032] Therefore, the provision of the flow sensor 8 and the flow control valve 7 is very necessary.

[0033] In this embodiment, the lower end of the aeration tank 9 is fixed to the base frame 10; an air outlet window is also provided on the top of the aeration tank 9; the air outlet window can release the air oxidized by the electrolytic manganese solution to ensure the normal operation of the aeration tank 9.

[0034] In this embodiment, a guardrail 11 is fixed to the top of the aeration tank 9 . The guardrail 11 is arranged in a C-shape, and a ladder 12 is provided at the opening of the guardrail 11 . The lower end of the ladder 12 is welded to the base frame 10 .

[0035] The working principle of the utility model is as follows: the permanent magnet variable frequency screw air compressor 1 compresses the gas and then delivers it to the compression tank 4 for storage. The compression tank 4 delivers the compressed air to the aeration tank 9 through the delivery pipe 6; the aeration motor 13 drives the aeration stirring paddle 14 to rotate and stir the electrolytic manganese solution, thereby increasing the contact area between the electrolytic manganese solution and oxygen in the air, allowing oxygen to fully contact with ferrous ions, causing the electrolytic manganese solution to produce uniform and fine bubbles, promoting the oxidation of ferrous ions, creating good conditions for the oxidation reaction, and thus improving the iron removal efficiency;

[0036] The arrangement of the compression tank 4 and the pressure gauge 5 provides a stable gas source for aeration of the electrolytic manganese solution; the flow control valve 7 and the flow sensor 8 can monitor the flow of the compressed gas and control the opening and closing;

[0037] The oxidized iron ions are hydrolyzed at a certain pH value to form iron hydroxide precipitates. The continuous supply of air helps to maintain the redox state and pH value in the electrolytic manganese solution relatively stable (through the balancing effect of consuming hydrogen ions in the oxidation reaction), which is beneficial to the complete formation of the iron hydroxide precipitate and the subsequent precipitation and separation operation, so that iron can be more effectively removed from the electrolytic manganese solution.
