Description

[0002] Manganese sulfate is an important basic chemical raw material, widely used in fertilizers, coatings, catalysts, ceramics, mineral processing and other fields.

Lithium manganese oxide and nickel-cobalt-manganese multi-element materials are the core direction of the demand for lithium-ion power battery materials. With the gradual promotion and application of lithium-ion power batteries in new energy vehicles, the demand for high-purity manganese sulfate will explode.

[0011] Preferably, the feeding assembly includes a second driving motor, the output end of the second driving motor is sleeved with a third gear, one end of the third gear is meshed with a fourth gear, a first rotating belt is arranged above the fourth gear, and both ends of the first rotating belt are sleeved with conveying pipes.

[0012] Preferably, the upper end of each of the conveying pipes is connected to a storage cavity, and a circular connecting block is connected to the inner cavity of each of the storage cavity. The upper end of the circular connecting block arranged at one end close to the second driving motor is connected to a guide tube, a guide groove is provided on the outer surface of the guide tube, and a floating block is connected to the inner cavity of the guide tube, the lower end of the guide tube is connected to a circular trigger block, and the storage cavity in the feeding assembly is connected to the reactor through the connecting block.

[0014] Preferably, a method for preparing high-purity manganese sulfate using industrial manganese comprises the following steps:

[0015] S1. First, industrial manganese is put into a ball mill for crushing, and the particle size of the powder is uniform. Then, the crushed manganese material is taken out. At this time, the crushed manganese material is put into a cleaning container, and enough clean water is added to the cleaning container to cover the manganese material. Then, a stirrer is used to make the water and the manganese material fully contact to promote the dissolution and shedding of impurities. Then, the washed manganese material is filtered through a filter to remove impurities and solid particles suspended in the water. The filtered manganese material should be dried for standby use;

[0016] S2. After the manganese material is dried, the manganese material is placed in a storage chamber installed at one end away from the second drive motor, and then the sulfuric acid solution is placed in the storage chamber installed at one end close to the second drive motor until the storage chamber is filled with the raw materials. At this time, the second drive motor is started, and the third gear is rotated one circle, so that the fourth gear is rotated ninety degrees, and then the first rotating belt and the conveying pipe sleeved at both ends are rotated ninety degrees, and the rectangular conveying port is made to correspond to the rectangular feeding port, and then the manganese material and the sulfuric acid solution are allowed to enter the reaction chamber through the conveying pipe;

[0017] S3, as the raw material in the storage chamber decreases, the floating block will move downward along the guide groove. When the trigger groove opened at the lower end of the floating block coincides with the circular trigger block, a complete circuit will be formed, so that the second drive motor will reverse one circle, and then the conveying pipe will reverse 90 degrees, so that the rectangular conveying port is separated from the rectangular feeding port, and the conveying of raw materials into the reaction chamber will stop;

[0018] S4. When the raw material is transported to the reaction chamber, power is turned on, so that the annular heating wire heats up, thereby heating the raw material in the reaction chamber. When the temperature in the reaction chamber reaches 70°C, the guide rod transmits the temperature to the reaction agent, and the reaction agent generates gas at 70°C, thereby pushing the sliding block to move upward along the temperature control cavity, thereby generating a thrust on the second conductive block, thereby separating the second conductive block from the connecting groove opened at the upper end of the third conductive block, thereby stopping the annular heating wire from heating;

[0019] S5. When the temperature in the reaction chamber reaches 70° C., the first drive motor is started to drive the rotation of the first gear, thereby driving the rotation of the second gear, and then driving the stirring rod to stir the reaction material, so that the manganese material and sulfuric acid can fully react. When the manganese material is completely dissolved, the stirring and heating are stopped, and then the solution is cooled to room temperature and taken out. At this time, the dissolved and cooled manganese sulfate solution is slowly poured into the filter, and then the filtering device is started to allow the solution to pass through the filter, and solid particles and impurities are intercepted on the filter medium, while the clear solution flows into the receiving container;

[0020] S6. When the solution completely passes through the filter, stop the operation of the filtering device, take out the filtered product in the receiving container, and then slowly pour the filtered manganese sulfate solution into the crystallization container, and adjust the temperature in the crystallization container according to the crystallization temperature of manganese sulfate, and then start the stirring device in the crystallization container to stir the solution, so that the solution is fully heated to promote the formation and growth of crystals. At the same time, during the crystallization process, regularly observe the state of the solution, such as the turbidity of the solution and the morphology of the crystals, to determine whether the crystallization has reached the desired degree;

[0021] S7. When the crystallization in the solution reaches the desired degree, stop heating or cooling to end the crystallization process, then separate the crystals and the solution in the crystallization container by a centrifuge, and dry the separated crystals to remove surface moisture to obtain dry manganese sulfate crystals. Finally, collect the dry manganese sulfate crystals, package and store them for subsequent use.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. In the present invention, when the temperature in the reaction chamber reaches 70°C, the reaction reagent will undergo a chemical reaction to generate gas. As the gas increases, an upward thrust is generated on the sliding block, so that the sliding block moves upward, and then an upward thrust is generated on the second conductive block, and the second conductive block is separated from the connecting groove opened at the upper end of the third conductive block, thereby cutting off the power to the annular heating wire and stopping the heating of the annular heating wire, so that the temperature in the reaction chamber is maintained at 70°C. In this way, the decomposition reaction of the reaction reagent can achieve a physical power-off effect, thereby improving the accuracy of temperature control in the reaction chamber, and then improving the work efficiency of purifying manganese sulfate.

[0024] 2. In the present invention, by making the diameter of the rectangular feed port far from the second drive motor and the diameter of the rectangular feed port equal to half of the diameter of the rectangular feed port close to the second drive motor and the diameter of the rectangular feed port, sulfuric acid and industrial manganese can be fed in proportion. When the trigger groove opened at the lower end of the floating block coincides with the circular trigger block, a complete circuit will be formed, so that the second drive motor will reverse one circle, and then the conveying pipe will reverse ninety degrees, so that the rectangular feed port is separated from the rectangular feed port, and the conveying of raw materials into the reaction chamber will be stopped. In this way, when the feeding reaches a specific amount, the feeding will be stopped, thereby improving the degree of automation of the device.

[0025] 3. In the present invention, when the temperature in the reaction chamber reaches 70 degrees Celsius, the temperature will be conducted to the temperature control chamber through the guide rod. When the reaction agent decomposes at 70 degrees Celsius, the reaction agent will produce gas. As the gas increases, a thrust will be generated on the sliding block, so that the sliding block moves upward. When the gas outlet opened at the lower end of the sliding block corresponds to the vent opened at the upper end of the temperature control chamber, the gas in the temperature control chamber will be discharged. In this way, the temperature in the reaction chamber can be monitored by the reaction agent, and monitoring the temperature of the reaction chamber by the reaction agent can improve the monitoring accuracy.

[0035] See also Figure 4 The purification component 6 includes a first drive motor 601, the output end of the first drive motor 601 is sleeved with a first gear 602, one end of the first gear 602 is meshed with a second gear 603, the middle part of the second gear 603 is connected to a guide rod 604, the inner cavity of the guide rod 604 is connected to a temperature control component 605, and the lower end surface of the guide rod 604 is connected to a plurality of stirring rods 606, and the first drive motor 601 is installed in the operating cavity 2, and the output end of the first drive motor 601 is connected to the first gear 602 through the lower end surface of the operating cavity 2.

A connecting groove is provided on the upper end surface of the third conductive block 404, and the connecting groove provided on the upper end of the third conductive block 404 matches with the second conductive block 403.

[0037] See also Figure 5 The temperature control component 605 includes a temperature control cavity 607, the inner cavity of the temperature control cavity 607 is filled with a reaction agent 608, and a plurality of ventilation holes 609 are arranged on the upper surface of the temperature control cavity 607, a sliding block 610 is connected to the upper inner cavity of the temperature control cavity 607, a plurality of air outlets 611 are opened at the lower end of the sliding block 610, and a feed pipe 612 is connected to one end of the temperature control cavity 607.

[0038] Specifically, when the temperature in the reaction chamber 5 reaches 70° C., the reaction agent 608 will undergo a chemical reaction to generate gas. As the gas increases, an upward thrust is generated on the sliding block 610, so that the sliding block 610 moves upward, thereby generating an upward thrust on the second conductive block 403, and separating the second conductive block 403 from the connecting grooves opened at the upper ends of the third conductive block 404, thereby cutting off the power to the annular heating wire 405, and stopping the heating of the annular heating wire 405, so that the temperature in the inner cavity of the reaction chamber 5 is maintained at 70° C. In this way, the decomposition reaction of the reaction agent 608 can achieve a physical power-off effect, thereby improving the accuracy of temperature control in the reaction chamber 5, and thereby improving the work efficiency of purifying manganese sulfate.

The sliding block 610 is made of insulating material. At the same time, the inner cavity of the lower end surface of the operating chamber 2 is hollow. When the gas generated by the reaction agent makes the air outlet 611 correspond to the ventilation holes 609, the gas in the temperature control chamber 607 will be discharged into the hollow cavity opened on the lower end surface of the operating chamber 2, and then discharged to the outside from the hollow cavity.

[0040] See also Figure 6 The feeding assembly 3 includes a second driving motor 301, the output end of the second driving motor 301 is sleeved with a third gear 302, one end of the third gear 302 is meshed with a fourth gear 303, a first rotating belt 304 is arranged above the fourth gear 303, and both ends of the first rotating belt 304 are sleeved with conveying pipes 305.

The upper end of the circular connecting block 307 arranged at one end close to the second driving motor 301 is connected to a guide tube 308, and a guide groove 309 is provided on the outer surface of the guide tube 308.

The storage cavity 306 in the feeding assembly 3 is connected to the reactor 1 through the connecting block.

[0042] Specifically, when the temperature in the reaction chamber 5 reaches 70 degrees Celsius, the temperature will be conducted to the temperature control chamber 607 through the guide rod 604. When the reaction agent 608 decomposes at 70 degrees Celsius, the reaction agent 608 will produce gas. As the gas increases, a thrust will be generated on the sliding block 610, so that the sliding block 610 moves upward. When the gas outlet 611 opened at the lower end of the sliding block 610 corresponds to the vent 609 opened at the upper end of the temperature control chamber 607, the gas in the temperature control chamber 607 will be discharged. In this way, the temperature in the reaction chamber 5 can be monitored by the reaction agent 608, and monitoring the temperature of the reaction chamber 5 by the reaction agent 608 can improve the monitoring accuracy.

[0043] The outer surface of the conveying pipe 305 sleeved on one end of the first rotating belt 304 near the second driving motor 301 is connected to the fourth gear 303, the number of teeth arranged on the outer surface of the third gear 302 is equal to one-fourth of the number of teeth arranged on the outer surface of the fourth gear 303, the lower end surface of the floating block 310 is provided with a trigger groove, and the trigger groove arranged on the lower end surface of the floating block 310 is matched with the circular trigger block 311, the outer surface of the circular connecting block 307 is provided with a plurality of rectangular feeding ports, and the upper end surface of each conveying pipe 305 is provided with a plurality of rectangular shaped feed port, and the diameter of the rectangular feed port opened near the second drive motor 301 and the diameter of the rectangular feed port are equal to half the diameter of the rectangular feed port opened away from the second drive motor 301 and the diameter of the rectangular feed port.

When the trigger groove at the lower end of the float 310 coincides with the circular trigger block 311, a complete circuit is formed, so that the second drive motor 301 reverses one circle, and then the delivery pipe 305 reverses ninety degrees, so that the rectangular feed port is separated from the rectangular feed port, and the delivery of raw materials to the reaction chamber 5 is stopped. In this way, when the material delivery reaches a specific amount, the material delivery will be stopped, thereby improving the degree of automation of the device.

[0045] A method for preparing high-purity manganese sulfate using industrial manganese comprises the following steps:

[0046] S1. First, industrial manganese is put into a ball mill for crushing, and the particle size of the powder is uniform. Then, the crushed manganese material is taken out. At this time, the crushed manganese material is put into a cleaning container, and enough clean water is added to the cleaning container to cover the manganese material. Then, a stirrer is used to make the water and the manganese material fully contact to promote the dissolution and shedding of impurities. Then, the washed manganese material is filtered through a filter to remove impurities and solid particles suspended in the water. The filtered manganese material should be dried for standby use;

[0047] S2. After the manganese material is dried, the manganese material is placed in the storage chamber 306 installed at one end away from the second drive motor 301, and then the sulfuric acid solution is placed in the storage chamber 306 installed at one end close to the second drive motor 301, until the storage chamber 306 is filled with raw materials. At this time, the second drive motor 301 is started, and the third gear 302 is rotated one circle, so that the fourth gear 303 is rotated ninety degrees, and then the first rotating belt 304 and the conveying pipe 305 with both ends connected are rotated ninety degrees, and the rectangular conveying port is made to correspond to the rectangular feeding port, and then the manganese material and the sulfuric acid solution are allowed to enter the reaction chamber 5 through the conveying pipe 305;

[0048] S3, as the raw material in the storage chamber 306 decreases, the floating block 310 moves downward along the guide groove 309, and when the trigger groove at the lower end of the floating block 310 overlaps with the circular trigger block 311, a complete circuit is formed, so that the second driving motor 301 reverses one circle, and then the conveying pipe 305 reverses ninety degrees, so that the rectangular conveying port is separated from the rectangular feeding port, and the conveying of raw materials into the reaction chamber 5 stops;

[0049] S4. When the raw material is transported to the reaction chamber 5, power is turned on, so that the annular heating wire 405 generates heat, thereby heating the raw material in the reaction chamber 5. When the temperature in the reaction chamber 5 reaches 70°C, the guide rod 604 transmits the temperature to the reaction agent 608. The reaction agent 608 generates gas at 70°C, thereby pushing the sliding block 610 to move upward along the temperature control cavity 607, thereby generating a thrust on the second conductive block 403, thereby separating the second conductive block 403 from the connecting groove opened at the upper end of the third conductive block 404, thereby stopping the annular heating wire 405 from heating.

[0050] S5. When the temperature in the reaction chamber 5 reaches 70° C., the first drive motor 601 is started to drive the first gear 602 to rotate, thereby driving the second gear 603 to rotate, and then driving the stirring rod 606 to stir the reaction material to allow the manganese material to fully react with the sulfuric acid. When the manganese material is completely dissolved, the stirring and heating are stopped, and then the solution is cooled to room temperature and taken out. At this time, the dissolved and cooled manganese sulfate solution is slowly poured into the filter, and then the filtering device is started to allow the solution to pass through the filter, and the solid particles and impurities are intercepted on the filter medium, while the clear solution flows into the receiving container;

[0051] S6. When the solution completely passes through the filter, stop the operation of the filtering device, take out the filtered product in the receiving container, and then slowly pour the filtered manganese sulfate solution into the crystallization container, and adjust the temperature in the crystallization container according to the crystallization temperature of manganese sulfate, and then start the stirring device in the crystallization container to stir the solution, so that the solution is fully heated to promote the formation and growth of crystals. At the same time, during the crystallization process, regularly observe the state of the solution, such as the turbidity of the solution and the morphology of the crystals, to determine whether the crystallization has reached the desired degree;

[0052] S7. When the crystallization in the solution reaches the desired degree, stop heating or cooling to end the crystallization process, then separate the crystals and the solution in the crystallization container by a centrifuge, and dry the separated crystals to remove surface moisture to obtain dry manganese sulfate crystals. Finally, collect the dry manganese sulfate crystals, package and store them for subsequent use.

5. A method for preparing high-purity manganese sulfate using industrial manganese, according to the device for preparing high-purity manganese sulfate using industrial manganese according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. First, industrial manganese is put into a ball mill for crushing, and the particle size of the powder is uniform. Then, the crushed manganese material is taken out. At this time, the crushed manganese material is put into a cleaning container, and enough clean water is added to the cleaning container to cover the manganese material. Then, a stirrer is used to make the water and the manganese material fully contact to promote the dissolution and shedding of impurities. Then, the washed manganese material is filtered through a filter to remove impurities and solid particles suspended in the water. The filtered manganese material should be dried for standby use; S2. After the manganese material is dried, the manganese material is placed in a storage chamber (306) installed at one end away from the second drive motor (301), and then the sulfuric acid solution is placed in the storage chamber (306) installed at one end close to the second drive motor (301), until the storage chamber (306) is filled with the raw materials. At this time, the second drive motor (301) is started, and the third gear (302) is rotated one circle, so that the fourth gear (303) is rotated ninety degrees, and then the first rotating belt (304) and the conveying pipe (305) sleeved at both ends are rotated ninety degrees, and the rectangular conveying port is made to correspond to the rectangular feeding port, and then the manganese material and the sulfuric acid solution are allowed to enter the reaction chamber (5) through the conveying pipe (305); S3, as the amount of raw material in the material storage chamber (306) decreases, the floating block (310) moves downward along the guide groove (309), and when the trigger groove formed at the lower end of the floating block (310) overlaps with the circular trigger block (311), a complete circuit is formed, thereby causing the second drive motor (301) to reverse one circle, and then causing the conveying pipe (305) to reverse ninety degrees, so that the rectangular conveying port is separated from the rectangular feeding port, and the conveying of raw materials into the reaction chamber (5) stops; S4. When the raw material is transported to the reaction chamber (5), power is turned on, so that the annular heating wire (405) generates heat, thereby heating the raw material in the reaction chamber (5). When the temperature in the reaction chamber (5) reaches 70° C., the guide rod (604) transmits the temperature to the reaction agent (608). The reaction agent (608) generates gas at 70° C., thereby pushing the sliding block (610) to move upward along the temperature control cavity (607), thereby generating a thrust on the second conductive block (403), thereby separating the second conductive block (403) from the connecting groove opened at the upper end of the third conductive block (404), thereby stopping the annular heating wire (405) from generating heat; S5. When the temperature in the reaction chamber (5) reaches 70° C., the first drive motor (601) is started to drive the first gear (602) to rotate, thereby driving the second gear (603) to rotate, and further driving the stirring rod (606) to stir the reaction material to allow the manganese material to fully react with the sulfuric acid. When the manganese material is completely dissolved, the stirring and heating are stopped, and the solution is cooled to room temperature and taken out. At this time, the dissolved and cooled manganese sulfate solution is slowly poured into the filter, and then the filtering device is started to allow the solution to pass through the filter, and solid particles and impurities are intercepted on the filter medium, while the clear solution flows into the receiving container; S6. When the solution completely passes through the filter, stop the operation of the filtering device, take out the filtered product in the receiving container, and then slowly pour the filtered manganese sulfate solution into the crystallization container, and adjust the temperature in the crystallization container according to the crystallization temperature of manganese sulfate, and then start the stirring device in the crystallization container to stir the solution, so that the solution is fully heated to promote the formation and growth of crystals. At the same time, during the crystallization process, regularly observe the state of the solution, and observe the turbidity of the solution and the morphology of the crystals to determine whether the crystallization has reached the desired degree; S7. When the crystallization in the solution reaches the desired degree, stop heating or cooling to end the crystallization process, then separate the crystals and the solution in the crystallization container by a centrifuge, and dry the separated crystals to remove surface moisture to obtain dry manganese sulfate crystals. Finally, collect the dry manganese sulfate crystals, package and store them for subsequent use.
