[0020] A method for using a novel nanomaterial preparation and modification integrated device specifically comprises the following steps:

[0021] S1, adding a metal salt solution dissolved in ionized water and a (NH4)2CO3 solution into the solution mixing chamber, and then stirring and mixing them by a stirring rod No. 1, so that the ions in the solution react with each other to form a precipitate;

[0022] S2, start the suction pump to pump the reacted mixed solution into the separation chamber, filter it through the screening disk, and separate the precipitate;

[0023] S3, washing the precipitate with ionized water through a nozzle to remove impurities;

[0024] S4, sending the washed precipitate to the inside of the storage drawer through the driving component, and then taking it out for drying and calcining to form the required nano powder, thereby completing the preparation;

[0025] S5. Add the nano powder and the coupling agent into the modified stirring chamber and add the solvent to stir and mix, ensuring that the coupling agent can evenly cover the surface of the nano powder, so that the coupling agent can complete the modification through reaction.

[0026] In the present application, 1. After adding a metal salt solution dissolved in ionized water and a (NH4)2CO3 solution into the solution mixing chamber, a No. 2 servo motor is driven to rotate a No. 1 stirring rod through a synchronous wheel and a synchronous belt to stir and mix the solution, so that the ions in the solution react with each other to form a precipitate;

[0027] 2. Start the suction pump to pump the reacted mixed liquid into the separation chamber, filter the liquid through the screening plate and discharge it through the drainage hole, thereby separating the precipitate;

[0028] 3. The ionized water is used to wash the sediment through the nozzle to remove impurities. The water is discharged through the drainage hole. At the same time, the No. 2 servo motor is driven to rotate the round shaft through the synchronous wheel and the synchronous belt. The round shaft drives the crankshaft to rotate. Since the connecting plate is connected to the screening disc at this time, and the screening disc is in a sliding state inside the separation chamber, the screening disc is driven to move back and forth horizontally to help flushing;

[0029] 4. After the end, the motor is driven, and the motor drives the threaded rod to rotate, and the threaded rod drives the rack and the threaded block to move horizontally. When the threaded block touches the inclined surface of the triangular block, it will push the triangular block and the U-shaped plate to move upward, so that the U-shaped plate is out of the slot, so that the connection between the screening plate and the connecting plate is released. Then the rack will touch the gear. Since the screening plate is limited by the upper limit bar and the lower limit bar, it can only move horizontally, so that the rack will push the screening plate to move and make it out of the range of the U-shaped plate engagement. Then the threaded block leaves the bottom of the triangular block, and the U-shaped plate returns to its original position. Then the rack drives the screening plate to move by pushing the gear. When the screening plate moves to the inside of the upper cavity, since the lower limit bar extends to the inside of the upper cavity, but the upper limit bar does not, the top of the screening plate will lose its constraint at this time. When the rack continues to move, it will rotate with the gear, and the gear drives the screening plate to rotate. Then the sediment will fall through the lower cavity to the inside of the storage drawer to complete the collection. Then the motor is driven in the reverse direction to drive the rack and the threaded block to reset. At this time, the rack will pass through the gear The wheel drives the screening plate to rotate and fit into the lower limit bar, and then drives the screening plate to move. When the threaded block touches the triangular block, it will push the triangular block and the U-shaped plate to move upward. At this time, the rack will also drive the screening plate to move to its original position and be located under the U-shaped plate. Then the threaded block continues to move away from the bottom of the triangular block, so that the U-shaped plate will move downward and connect the screening plate and the connecting plate through the slot, so that the crankshaft can drive the screening plate to move horizontally through the connecting plate 36, and in order to avoid the screening plate passing through the crankshaft position When the U-shaped plate is engaged with the screening disc and the connecting plate, it continues to drive the rack to move. Since the upper limit bar and the lower limit bar are both provided with inclined surfaces at one end close to the side and the other end away from the side, the rack can drive the screening disc 17 to rotate by driving the gear when moving, so that it is out of the gear pitch and avoids being constrained by the rack to ensure normal movement. When the screening disc rotates, the pressure plate will be lifted. After that, when the rack is away, the pressure plate will be reset by the compression spring to press the screening disc to a horizontal state.

[0030] 5. Then take it out for drying and calcination to form the required nano powder and complete the preparation;

[0031] 6. Add the prepared nanopowder to the inside of the modified stirring chamber, and then add a coupling agent, such as titanate coupling agent, aluminate coupling agent, etc., drive the No. 1 servo motor to drive the No. 2 stirring rod to rotate, so as to stir and mix the coupling agent and the nanopowder, mix the nanopowder and the coupling agent in a suitable solvent, ensure that the coupling agent can evenly cover the surface of the nanopowder, so that it can be modified through reaction, and then it can be taken out by suction pump and other equipment.

[0032] In the present invention, the novel nanomaterial preparation and modification integrated equipment and method can collect the washed sediment through the driving assembly, and the sieving disc can be displaced and rotated by the positive driving motor to collect the sediment into the storage bin, and then the sieving disc can be taken out for drying and calcination to obtain nano powder, and then the sieving disc can be reset and matched with the crankshaft again by reverse driving;

[0033] In the present invention, the novel integrated equipment and method for preparing and modifying nanomaterials can achieve mixing of nanopowders and coupling agents in a solvent by modifying the stirring chamber, thereby ensuring that the coupling agent can evenly cover the surface of the nanopowders, so that the nanopowders are modified through reaction;

[0034] In the present invention, when in use, the solution in the raw material is added to the solution mixing chamber and stirred and mixed to form a precipitate, which is then pumped into the sieving plate and washed to remove impurities. The precipitate can then be collected by a driving component, and then dried and calcined to complete the preparation of the nanopowder.

[0035] Then, the nanopowder and the coupling agent are mixed in a suitable solvent to ensure that the coupling agent can evenly cover the surface of the nanopowder so that the modification is completed through reaction. BRIEF DESCRIPTION OF THE DRAWINGS
