[0020] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kind of manganese carbonate preparation device, including electrolytic tank 1, liquid inlet pipe 2, pressure relief pipe 3, graphite anode 4, stainless steel cathode 5, air charging pipe 6, air jet nozzle 7, servo motor 8, flow promoting fan blade 9, liquid outlet pipe 10, transfer pipe 11, separation tank 12, waste discharge pipe 13, installation window 14, filter frame 15, positioning groove 16 and filter cloth 17, electrolytic tank 1 top side is fixed with liquid inlet pipe 2, electrolytic tank 1 top center is installed with pressure relief pipe 3, electrolytic tank 1 top two sides are installed with graphite anode 4 and stainless steel cathode 5 respectively, air charging pipe 6 is fixedly installed on the top of electrolytic tank 1 near stainless steel cathode 5 side, air jet nozzle 7 is installed on the side of air charging pipe 6 close to stainless steel cathode 5, servo motor 8 is fixed on the side of electrolytic tank 1, flow promoting fan blade 9 is installed on the output shaft end of servo motor 8, liquid outlet pipe 10 is installed on the bottom of electrolytic tank 1, transfer pipe 11 is installed on the bottom center of electrolytic tank 1, electrolytic tank 1 is fixed on separation tank 12, transfer pipe 11 bottom end is connected and fixed with the top end of separation tank 12, waste discharge pipe 13 is installed on the bottom of one side of separation tank 12, installation window 14 is arranged on the other side of separation tank 12, filter frame 15 is installed in installation window 14, filter frame 15 bottom end is attached with positioning groove 16, positioning groove 16 is arranged on the inner wall of separation tank 12, filter cloth 17 is installed on the bottom of the inner side of filter frame 15.

[0021] The air charging pipe 6 of the example is symmetrically distributed about the center of the stainless steel cathode 5, and the center of the stainless steel cathode 5 and the center of the air charging pipe 6 are on the same vertical plane. The above structure design ensures that the CO2 sprayed out of the air jet nozzle 7 of the air charging pipe 6 can fully contact the Mn(OH)2 precipitated near the stainless steel cathode 5.

[0022] The air injection nozzle 7 is arranged obliquely downward, and the air injection nozzle 7 is arranged at equal intervals on the side of the inflation pipe 6 close to the stainless steel cathode 5. The above structure can avoid the attachment of Mn(OH)2 on the stainless steel cathode 5, and promote the rapid downward movement of the generated MnCO3.

[0023] The flow-promoting fan blade 9 is arranged directly below the liquid inlet pipe 2, and the flow-promoting fan blade 9 is arranged at the horizontal center of the electrolysis box 1. The above structure can promote the flow of the electrolyte in the electrolysis box 1, and realize sufficient electrolysis.

[0024] The installation window 14 and the positioning groove 16 are arranged at equal intervals on both sides of the separation box 12. The installation window 14 is in sliding connection with the filter frame 15, and the positioning groove 16 is in clamping connection with the bottom of the filter frame 15. The above structure design makes the filter frame 15 convenient to install and disassemble.

[0025] The filter frame 15 is arranged obliquely, and the outer side wall of the filter frame 15 is attached to the inner wall of the separation box 12. The inner wall bottom surface of the separation box 12 is arranged as an inclined surface. The above structure design can avoid the single displacement accumulation of the intercepted MnCO3 on the inside filter cloth 17 of the filter frame 15, and ensure the rapid filtering and interception effect.

[0026] Working principle: all valves on the pipeline are in a closed state first. When using the device, first open the pressure relief pipe 3, open the valve on the liquid inlet pipe 2, and pass the electrolyte into the electrolysis box 1 until the electrolyte is sufficient. Then, close the valve on the liquid inlet pipe 2, pass electricity to the graphite anode 4 and the stainless steel cathode 5, and start the servo motor 8. The servo motor 8 drives the flow-promoting fan blade 9 to rotate, and promotes the flow of the electrolyte.

[0027] Mn(OH)2 is precipitated near the stainless steel cathode 5. At this time, the CO2 in the external gas cylinder is sprayed near the stainless steel cathode 5 through the air injection nozzle 7 connected by the inflation pipe 6. The CO2 fully contacts with the Mn(OH)2, and reacts to generate MnCO3. The MnCO3 is settled downward under the action of the sprayed CO2, and is deposited on the inside bottom of the electrolysis box 1.

[0028] Periodically open the valve on the transfer pipe 11 to discharge the MnCO3 precipitated at the bottom of the electrolysis box 1 together with a small amount of electrolyte into the separation box 12. Periodically discharge the waste electrolyte produced through the liquid discharge pipe 10, and add new electrolyte through the liquid inlet pipe 2.

[0029] The precipitated MnCO3 and a small amount of electrolyte enter the separation tank 12, and then fall on the filter cloth 17 inside the filter frame 15, the MnCO3 is intercepted by the filter cloth 17, and as the MnCO3 and the electrolyte continuously fall, the MnCO3 will not accumulate at the same position on the inclined filter cloth 17, and the electrolyte smoothly passes through the filter cloth 17, the filter frame 15 is regularly taken out from the installation window 14, the intercepted MnCO3 is collected, and the cleaned filter frame 15 is inserted into the installation window 14, so that the bottom end of the filter frame 15 is reset by being clamped with the positioning groove 16, and the remaining electrolyte finally falls at the bottom of the separation tank 12 and is discharged and collected through the waste discharge pipe 13, which is the working principle of the manganese carbonate preparation device.
