Description

Technical Field

[0001] This invention relates to the field of nano-ITO powder pretreatment technology, and in particular to a pretreatment apparatus and method for improving the performance of nano-ITO powder. Background Technology

[0002] Indium tin oxide (ITO) is a class of heavily doped, highly degenerate semiconductor materials. ITO thin films possess characteristics such as ultraviolet light cutoff, high visible light transmittance, high infrared light reflectivity, strong microwave attenuation, and low resistivity, making them widely used in solar cells, liquid crystal displays, stealth coatings, transparent thermal insulation materials, antistatic coatings, and many other fields. During preparation and use, ITO powder requires various heat treatment methods. The performance of TTO primarily depends on the microstructure and state of the ITO nanoparticles. Therefore, improving the performance of ITO nanoparticles necessitates preparing the necessary materials for their preparation.

[0003] The invention disclosed in publication number CN101628814A presents a method for preparing ITO nanopowder:

[0004] (1) The indium-tin mixed precursor precipitate is obtained by mixing the indium salt and tin salt mixture with an alkaline solution; or the indium precursor precipitate is obtained by mixing the indium salt solution with an alkaline solution, and the tin precursor precipitate is obtained by mixing the tin salt solution with an alkaline solution; wherein the alkaline solution is ammonia water or sodium hydroxide or potassium hydroxide or sodium carbonate or ammonium bicarbonate solution.

[0005] (2) The indium-tin mixed precursor precipitate or indium precursor precipitate and tin precursor precipitate obtained in step (1) is washed with deionized water or distilled water and filtered to obtain indium-tin mixed precursor or indium precursor and tin precursor.

[0006] (3) The indium-tin mixed precursor or indium precursor and tin precursor obtained in step (2) is freeze-dried and dehydrated using a freezer to obtain indium-tin mixed precursor freeze powder or indium precursor freeze powder and tin precursor freeze powder.

[0007] (4) Calcining the freeze-dried powder obtained in step (3) to obtain indium tin oxide powder or indium oxide powder and tin oxide powder;

[0008] (5) Mix the indium oxide powder and tin oxide powder obtained in step (4) to obtain indium tin oxide powder.

[0009] However, the existing technology still has the following shortcomings in the preparation process:

[0010] 1. When preparing ITO nanopowder, it is necessary to obtain a mixture of indium salt and tin salt. The ratio of the indium salt and tin salt mixture needs to be precise. In the existing technology, it is necessary to manually mix the indium salt and tin salt. The ratio of the indium salt and tin salt mixture is also different depending on the ratio. Therefore, relying on manual mixing is cumbersome, time-consuming and labor-intensive, and it is easy to make mistakes in the ratio.

[0011] 2. In existing technologies, indium and tin salts are often added to the beaker at the same time when preparing indium-tin mixtures. However, adding indium and tin salts at the same time can easily lead to insufficient mixing of indium and tin salts.

[0012] 3. When preparing the indium-tin mixture, the mixture in the beaker is prone to splashing out, which not only causes waste but also easily causes pollution.

[0013] To address the aforementioned problems, this invention proposes a pretreatment device and method for improving the properties of nano-ITO powder. Summary of the Invention

[0014] This invention provides a pretreatment device and method for improving the performance of nano ITO powder, which solves the problem of the shortcomings of the prior art, which requires manual proportioning and adding indium salt and tin salt into the beaker at one time, and the mixture in the beaker is prone to splashing out.

[0015] This invention provides the following technical solution:

[0016] A pretreatment apparatus for improving the properties of nano ITO powder includes: a workbench and a beaker, wherein a placement tray is fixedly connected to the top of the workbench and the beaker is placed on the top of the placement tray;

[0017] The feeding structure is located inside the workbench and is used to periodically add indium salts and tin salts into the beaker;

[0018] A mixing structure for automatically mixing indium and tin salts;

[0019] A splash-proof structure is installed at the top of the beaker to prevent solution splashing during the preparation of indium tin solution.

[0020] In one possible design, the feeding structure includes a transmission chamber disposed within a workbench. Two movable rods are slidably connected to the bottom inner wall of the transmission chamber. The tops of the movable rods extend above the workbench. A slide rod is slidably connected within each movable rod. A self-locking structure for locking the slide rod is provided at the top of the movable rod. A fixing frame is fixedly fitted onto the outer wall of the slide rod. A retaining ring is fixedly connected to one side of the fixing frame, and a bottle is held in place within the retaining ring. A fixing block is fixedly connected within the fixing frame, and the top of the slide rod slides through the fixing block. A rotating ring is rotatably connected to the bottom inner wall of the fixing frame. The slide rod... The outer wall is fitted with a torsion spring fixedly connected to the top of the rotating ring, and the top of the torsion spring is fixedly connected to the bottom of the fixing block. A sealing plate for sealing the placement bottle is fixedly connected to one side of the rotating ring. An inclined plate is fixedly connected to the end of the sealing plate near the beaker. When the moving rod drives the fixing frame to move towards the beaker, the two inclined plates touch each other. Under the mutual squeezing action of the two inclined plates, the corresponding rotating ring and sealing plate are rotated respectively. At this time, the indium salt and tin salt in the two placement bottles can be put into the beaker. Conversely, the placement bottles can be sealed at the same time, so that the indium salt and tin salt can be put into the two placement bottles at the same time.

[0021] In one possible design, the proportioning structure includes a discharge nozzle fixedly connected to the bottom of the bottle. A sliding plate is slidably connected inside the discharge nozzle, and the sliding plate has multiple discharge holes. Multiple slots are provided on the opposite sides of the sliding plate. A groove is provided on the inner wall of the opposite side of the discharge nozzle. A wedge block that mates with the slot is slidably connected within the groove. A first spring is fixedly connected to the end of the wedge block away from the sliding plate, and one end of the first spring is fixedly connected to the inner wall of one side of the groove. Moving the sliding plate allows the discharge holes to move to the center position of the discharge nozzle. The engagement of the slots and the wedge block positions the sliding plate. Furthermore, the amount of indium and tin salts added to the beaker simultaneously can be controlled by adjusting the inner diameter of the discharge holes in the two discharge nozzles, thus enabling automatic proportioning. This method is simple and convenient, requiring no manual proportioning by personnel.

[0022] In one possible design, the anti-splash structure includes a detachable semicircular plate mounted on the top of the beaker. Two tension springs are fixedly connected to one side of the semicircular plate, and one end of each tension spring is fixedly connected to the same anti-splash plate. The bottom of the anti-splash plate slides against the top of the beaker. A stop block is fixedly connected to the top of the anti-splash plate. When the two inclined plates come into contact with each other and rotate, the inclined plates push the anti-splash plate outward through the stop block, opening the beaker and allowing any falling indium and tin salts to enter the beaker, thus ensuring thorough mixing. When the fixed frame moves outward, the anti-splash plate returns to its original position under the tension of the tension springs, sealing the beaker and preventing the solution from splashing out of the beaker when the indium and tin salts are stirred.

[0023] In one possible design, the self-locking structure includes a nut block fixedly connected to the top of the moving rod, with a bolt threaded through the nut block. One side of the slide rod is provided with multiple pin slots that mate with the bolts. The self-locking structure can also be a positioning pin that mates with the pin slots. This is not limited here. The movement of the slide rod and the fixed frame can be controlled by the mate between the bolts and the pin slots, thereby controlling the height of the bottle and allowing the feeding structure to adapt to beakers of different heights.

[0024] In one possible design, the inner walls of the transmission chambers on opposite sides are rotatably connected to bidirectional lead screws. The ends of the two bidirectional lead screws that are close to each other are threaded through corresponding moving rods. A connecting rod is fixedly connected between the two bidirectional lead screws. A first bevel gear is fixedly sleeved on the outer wall of the connecting rod. A drive motor is fixedly connected to one side of the worktable, and the output shaft of the drive motor extends into the transmission chamber and is fixedly connected to one end of the connecting rod. A second bevel gear is rotatably connected to the top inner wall of the transmission chamber, and the second bevel gear meshes with the first bevel gear. A rotating groove is provided in the placement tray, and a gearbox is fixedly connected in the rotating groove. The input shaft of the gearbox is fixedly connected to the top of the second bevel gear. A rotating disk is fixedly connected to the output shaft of the gearbox. First magnetic blocks are fixedly connected to both sides of the top of the rotating disk. A stirring plate is provided on the bottom inner wall of the beaker, and multiple second magnetic blocks that cooperate with the first magnetic blocks are fixedly connected to the bottom of the stirring plate.

[0025] In one possible design, multiple stirring plates are fixedly connected to the top of the stirring pan. When the stirring pan rotates, the stirring plates can drive the solution in the beaker to rotate to the maximum extent, so that the indium salt and tin salt added later can be fully mixed in the solution.

[0026] In one possible design, the inner diameters of the multiple discharge holes increase sequentially, thereby controlling the ratio of indium salt and tin salt entering the beaker from the two placement bottles by controlling the size of the inner diameter of the discharge holes in the two discharge nozzles.

[0027] In one possible design, the stirring plate has a circular hole, and the inner walls of the opposite sides of the circular hole have triangular grooves. An extraction rod is installed in the circular hole, and the extraction rod has a rectangular hole. Two wedge plates are slidably connected in the rectangular hole, and the wedge plates cooperate with the triangular grooves. The two wedge plates are elastically connected by multiple second springs. After mixing, the semi-circular plate and the splash guard are removed from the top of the beaker, and the extraction rod is inserted into the circular hole. The extraction rod drives the wedge plates to extend into the circular hole, and the wedge plates extend into the triangular grooves under the elastic force of the second springs. At this time, the extraction rod is connected to the stirring plate through the wedge plates, and the stirring plate can be removed from the beaker through the extraction rod, allowing the mixed solution in the beaker to proceed to the next process.

[0028] The method of using the pretreatment device for improving the properties of nano-ITO powder includes the following steps:

[0029] S1. First, add water to the beaker and start the drive motor to drive the bidirectional lead screw, connecting rod and first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The gearbox and the second bevel gear work together to quickly drive the rotating disk to rotate. The rotating disk drives the stirring disk to rotate quickly through the magnetic attraction between the first magnetic block and the second magnetic block, which in turn drives the water in the beaker to rotate, making it easier to add indium salt and tin salt later.

[0030] S2. According to the ratio of indium salt and tin salt, move the sliding plate in the two discharge nozzles respectively. At this time, the height of the two placement bottles is the same. By controlling the size of the discharge hole, the capacity of indium salt and tin salt falling from the two placement bottles at the same time can be controlled, so that the required ratio can be automatically completed without manual mixing.

[0031] S3. When the stirring plate rotates, the double-acting screw drives the moving rod to move, and the moving rod drives the fixed frame and the placement bottle to move towards the beaker. When the two placement bottles approach each other, the two inclined plates touch each other. As the two fixed frames continue to approach each other, the two inclined plates squeeze each other, causing the closing plate and the rotating ring to rotate. The torsion spring begins to store force, and the rotation of the closing plate releases the seal on the discharge nozzle. At this time, the indium salt and tin salt contained in the two placement bottles fall downward through the discharge nozzle.

[0032] S4. Additionally, when the two inclined plates come into contact with each other and rotate, the inclined plates push the anti-splash plate outward through the stop block, opening the beaker and allowing the falling indium and tin salts to enter the beaker, so that the indium and tin salts can be fully mixed in the beaker. As the bidirectional screw continues to rotate, the bidirectional screw drives the fixed frame to move outward, and the anti-splash plate resets and closes the beaker under the tension of the tension spring, preventing the solution from splashing out of the beaker when the indium and tin salts are stirred in the beaker. As the two fixed frames move away from each other, the rotating ring and the closing plate reset and re-close the discharge nozzle under the action of the torsion spring, so that the indium and tin salts in the two placement bottles fall at the same time. Thus, by controlling the size of the inner diameter of the discharge hole at the bottom of the two placement bottles, the volume of indium and tin salts entering the beaker can be controlled to achieve the purpose of automatic proportioning.

[0033] S5. As the bidirectional lead screw rotates, it drives the fixed frame to move back and forth, thereby continuously adding the pre-mixed indium and tin salts to the beaker in a timed and quantitative manner. The gradual addition of indium and tin salts allows them to mix thoroughly and quickly in the beaker. After mixing, the semi-circular plate and splash guard are removed from the top of the beaker, and the extraction rod is inserted into the round hole. The extraction rod drives the wedge plate to extend into the round hole. Under the elastic force of the second spring, the wedge plate extends into the triangular groove. At this time, the extraction rod is connected to the stirring plate through the wedge plate. The stirring plate can then be removed from the beaker through the extraction rod, allowing the mixed solution in the beaker to proceed to the next process.

[0034] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0035] In this invention, a sliding rod is slidably connected inside the moving rod, and a fixed frame is fixedly sleeved on the outer wall of the sliding rod. A rotating ring is rotatably connected to the bottom inner wall of the fixed frame. A sealing plate for sealing the placement bottle is fixedly connected to one side of the rotating ring, and an inclined plate is fixedly connected to one end of the sealing plate. When the moving rod drives the fixed frame to move towards the beaker, the two inclined plates collide and squeeze each other, causing the corresponding rotating ring and sealing plate to rotate. The indium salt and tin salt in the two placement bottles fall into the beaker. Conversely, the placement bottles can be sealed at the same time, so that the indium salt and tin salt can be added to the two placement bottles at the same time.

[0036] In this invention, a sliding plate is slidably connected inside the discharge nozzle. The sliding plate has multiple discharge holes. Multiple slots are provided on the opposite sides of the sliding plate. The inner walls of the opposite sides of the discharge nozzle are provided with sliding grooves. Wedge blocks are slidably connected inside the sliding grooves. By moving the sliding plate, the discharge holes are moved into the discharge nozzle. In addition, the amount of indium salt and tin salt added to the beaker at the same time can be controlled by the size of the inner diameter of the discharge holes in the two discharge nozzles. This allows for automatic proportioning, which is simple and convenient and does not require manual proportioning by personnel.

[0037] In this invention, two tension springs are fixedly connected to one side of the semicircular plate, and the same anti-splash plate is fixedly connected to one end of the two tension springs. A stop block is fixedly connected to the top of the anti-splash plate. When the two inclined plates come into contact with each other and rotate, the inclined plates push the anti-splash plate to move outward through the stop block, opening the beaker and allowing the falling indium salt and tin salt to enter the beaker, so that the indium salt and tin salt are fully mixed in the beaker. When the fixing frame moves outward, the anti-splash plate is reset and closes the beaker under the tension of the tension springs, so as to prevent the solution from splashing out of the beaker when the indium salt and tin salt are stirred in the beaker.

[0038] In this invention, the inner walls of the transmission chambers on opposite sides are rotatably connected to bidirectional lead screws. The ends of the two bidirectional lead screws that are close to each other are threaded through corresponding moving rods. A connecting rod is fixedly connected between the two bidirectional lead screws. A first bevel gear is fixedly sleeved on the outer wall of the connecting rod. When the bidirectional lead screws and the connecting rod rotate, the solution in the beaker can be stirred by the stirring plate. At the same time, the bidirectional lead screws can drive the moving rods and the fixed frame to move back and forth, thereby enabling the placement bottle to gradually add indium salt and tin salt into the beaker at regular intervals and in measured quantities, so that the indium salt and tin salt are fully mixed in the beaker.

[0039] In this invention, the ratio of indium salt and tin salt can be achieved by controlling the inner diameter of the discharge holes in the two discharge nozzles. Furthermore, the bidirectional lead screw drives the moving rod to rotate back and forth, which allows the placement bottle to gradually add indium salt and tin salt into the beaker, facilitating thorough mixing of the indium salt and tin salt in the beaker. In addition, when the indium salt and tin salt are thoroughly mixed in the beaker, splashing of the solution in the beaker can be avoided. Attached Figure Description

A feeding structure is set inside the workbench 1 for periodically feeding indium salt and tin salt into the beaker 2. A proportioning structure is used to automatically complete the proportioning of indium salt and tin salt. An anti-splashing structure is set on top of the beaker 2 to prevent solution splashing during the preparation of indium-tin solution.

[0059] Reference Figure 2 and Figure 3Two bidirectional lead screws 4 are rotatably connected to the inner walls of the transmission chamber 3 on opposite sides. The ends of the two bidirectional lead screws 4 that are close to each other are threaded through corresponding moving rods 16. A connecting rod 5 is bolted between the two bidirectional lead screws 4. A first bevel gear 6 is fixedly sleeved on the outer wall of the connecting rod 5.

A second bevel gear 11 is rotatably connected to the top inner wall of the transmission chamber 3. The second bevel gear 11 meshes with the first bevel gear 6. A rotating groove 9 is provided in the placement plate 8. A gearbox 10 is fixedly connected to the rotating groove 9 by bolts.

The bottom of the stirring plate 14 is fixedly connected to a plurality of second magnetic blocks 15 that cooperate with the first magnetic blocks 13 by bolts.

[0060] Reference Figure 3 Multiple stirring plates 37 are fixedly connected to the top of the stirring plate 14 by bolts. When the stirring plate 14 rotates, the stirring plates 37 can drive the solution in the beaker 2 to rotate to the maximum extent, so that the indium salt and tin salt added later can be fully mixed in the solution.

[0061] Reference Figure 8 The anti-splash structure includes a detachable semi-circular plate 26 on the top of beaker 2. Two tension springs 29 are fixedly connected to one side of the semi-circular plate 26. One end of the two tension springs 29 is fixedly connected to the same anti-splash plate 27, and the bottom of the anti-splash plate 27 slides in contact with the top of beaker 2. A stop block 28 is fixedly connected to the top of the anti-splash plate 27 by bolts. When the two inclined plates 25 come into contact with each other and rotate, the inclined plates 25 push the anti-splash plate 27 to move outward through the stop block 28, opening beaker 2, so that the falling indium salt and tin salt can enter beaker 2 and be fully mixed in beaker 2. When the fixing frame 18 moves outward, the anti-splash plate 27 is reset and closed by the tension of the tension springs 29, preventing the solution from splashing out of beaker 2 when the indium salt and tin salt are stirred in beaker 2.

[0062] Reference Figure 4 and Figure 5The feeding structure includes a transmission chamber 3 located within a workbench 1. Two movable rods 16 are slidably connected to the bottom inner wall of the transmission chamber 3. The tops of the movable rods 16 extend above the workbench 1. A sliding rod 17 is slidably connected within the movable rods 16. A self-locking structure for locking the sliding rod 17 is provided at the top of the movable rods 16. A fixing frame 18 is fixedly fitted onto the outer wall of the sliding rod 17. A retaining ring 19 is bolted to one side of the fixing frame 18, and a bottle 20 is held in place within the retaining ring 19.

A sealing plate 24 for sealing the placement bottle 20 is fixedly connected to one side of the rotating ring 22 by bolts. An inclined plate 25 is fixedly connected to the end of the sealing plate 24 near the beaker 2 by bolts. When the moving rod 16 drives the fixed frame 18 to move towards the beaker 2, the two inclined plates 25 touch each other. Under the mutual squeezing action of the two inclined plates 25, the corresponding rotating ring 22 and sealing plate 24 are rotated respectively. At this time, the indium salt and tin salt in the two placement bottles 20 can be just put into the beaker 2. Conversely, the placement bottles 20 can be sealed at the same time. Thus, the two placement bottles 20 can complete the addition of indium salt and tin salt at the same time.

[0063] Reference Figure 9 The self-locking structure includes a nut block 39 fixedly connected to the top of the moving rod 16 by bolts. The nut block 39 has a bolt 40 threaded through it. The slide rod 17 has multiple pin slots 38 on one side that cooperate with the bolts 40. The self-locking structure can also be a positioning pin that cooperates with the pin slots 38. This is not limited here. The cooperation between the bolts 40 and the pin slots 38 can control the lifting and lowering of the slide rod 17 and the fixing frame 18, thereby controlling the height of the bottle 20 and enabling the feeding structure to adapt to beakers 2 of different heights.

[0064] Reference Figure 6 and Figure 7The mixing structure includes a discharge nozzle 30, which is fixedly connected to the bottom of the bottle 20.

A groove 36 is provided on the inner wall of the side of the discharge nozzle 30 that is away from each other. A wedge-shaped block 35 that mates with the slot 33 is slidably connected inside the groove 36. A first spring 34 is fixedly connected to the end of the wedge-shaped block 35 that is away from the sliding plate 31. One end of the first spring 34 is fixedly connected to the inner wall of one side of the slide 36. By moving the sliding plate 31, the discharge hole 32 can be moved to the center position of the discharge nozzle 30. The cooperation between the slot 33 and the wedge block 35 can position the sliding plate 31. In addition, the amount of indium salt and tin salt added to the beaker 2 at the same time can be controlled by the size of the inner diameter of the discharge hole 32 in the two discharge nozzles 30. Thus, the proportioning can be completed automatically, which is simple and convenient and does not require special personnel to perform the proportioning.

[0065] Reference Figure 6 The inner diameters of the multiple discharge holes 32 increase sequentially, and by controlling the size of the inner diameter of the discharge holes 32 in the two discharge nozzles 30, the ratio of indium salt and tin salt entering the beaker 2 from the two placement bottles 20 can be controlled.

An anti-splashing structure is set on top of the beaker 2 to prevent solution splashing during the preparation of indium-tin solution.

[0068] Reference Figure 2 and Figure 3Two bidirectional lead screws 4 are rotatably connected to the inner walls of the transmission chamber 3 on opposite sides. The ends of the two bidirectional lead screws 4 that are close to each other are threaded through corresponding moving rods 16. A connecting rod 5 is bolted between the two bidirectional lead screws 4. A first bevel gear 6 is fixedly sleeved on the outer wall of the connecting rod 5. A drive motor 7 is bolted to one side of the worktable 1, and the output shaft of the drive motor 7 extends into the transmission chamber 3 and is fixedly connected to one end of the connecting rod 5 via a coupling. A second bevel gear 11 is rotatably connected to the top inner wall of the transmission chamber 3. The second bevel gear 11 meshes with the first bevel gear 6. A rotating groove 9 is provided in the placement plate 8. A gearbox 10 is fixedly connected to the rotating groove 9 by bolts. The input shaft of the gearbox 10 is fixedly connected to the top of the second bevel gear 11. The output shaft of the gearbox 10 is fixedly connected to the rotating disk 12. The top two sides of the rotating disk 12 are fixedly connected to the first magnetic blocks 13 by bolts. A stirring plate 14 is provided on the bottom inner wall of the beaker 2. The bottom of the stirring plate 14 is fixedly connected to a plurality of second magnetic blocks 15 that cooperate with the first magnetic blocks 13 by bolts.

[0069] Reference Figure 3 Multiple stirring plates 37 are fixedly connected to the top of the stirring plate 14 by bolts. When the stirring plate 14 rotates, the stirring plates 37 can drive the solution in the beaker 2 to rotate to the maximum extent, so that the indium salt and tin salt added later can be fully mixed in the solution.

[0070] Reference Figure 8 The anti-splash structure includes a detachable semi-circular plate 26 on the top of beaker 2. Two tension springs 29 are fixedly connected to one side of the semi-circular plate 26. One end of the two tension springs 29 is fixedly connected to the same anti-splash plate 27, and the bottom of the anti-splash plate 27 slides in contact with the top of beaker 2. A stop block 28 is fixedly connected to the top of the anti-splash plate 27 by bolts. When the two inclined plates 25 come into contact with each other and rotate, the inclined plates 25 push the anti-splash plate 27 to move outward through the stop block 28, opening beaker 2, so that the falling indium salt and tin salt can enter beaker 2 and be fully mixed in beaker 2. When the fixing frame 18 moves outward, the anti-splash plate 27 is reset and closed by the tension of the tension springs 29, preventing the solution from splashing out of beaker 2 when the indium salt and tin salt are stirred in beaker 2.

[0071] Reference Figure 4 and Figure 5The feeding structure includes a transmission chamber 3 located within a workbench 1. Two movable rods 16 are slidably connected to the bottom inner wall of the transmission chamber 3. The tops of the movable rods 16 extend above the workbench 1. A sliding rod 17 is slidably connected within the movable rods 16. A self-locking structure for locking the sliding rod 17 is provided at the top of the movable rods 16. A fixing frame 18 is fixedly fitted onto the outer wall of the sliding rod 17. A retaining ring 19 is bolted to one side of the fixing frame 18, and a bottle 20 is held in place within the retaining ring 19. A fixing block 21 is bolted to the fixing frame 18, and the top of the sliding rod 17 slides through the fixing block 21. A rotating ring 22 is rotatably connected to the bottom inner wall of the fixing frame 18, and a mechanism for engaging the rotating ring 22 is fitted onto the outer wall of the sliding rod 17. A torsion spring 23 is fixedly connected to the top, and the top of the torsion spring 23 is fixedly connected to the bottom of the fixed block 21. A sealing plate 24 for sealing the placement bottle 20 is fixedly connected to one side of the rotating ring 22 by bolts. An inclined plate 25 is fixedly connected to the end of the sealing plate 24 near the beaker 2 by bolts. When the moving rod 16 drives the fixed frame 18 to move towards the beaker 2, the two inclined plates 25 touch each other. Under the mutual squeezing action of the two inclined plates 25, the corresponding rotating ring 22 and sealing plate 24 are rotated respectively. At this time, the indium salt and tin salt in the two placement bottles 20 can be just put into the beaker 2. Conversely, the placement bottles 20 can be sealed at the same time. Thus, the two placement bottles 20 can complete the addition of indium salt and tin salt at the same time.

[0072] Reference Figure 9 The self-locking structure includes a nut block 39 fixedly connected to the top of the moving rod 16 by bolts. The nut block 39 has a bolt 40 threaded through it. The slide rod 17 has multiple pin slots 38 on one side that cooperate with the bolts 40. The self-locking structure can also be a positioning pin that cooperates with the pin slots 38. This is not limited here. The cooperation between the bolts 40 and the pin slots 38 can control the lifting and lowering of the slide rod 17 and the fixing frame 18, thereby controlling the height of the bottle 20 and enabling the feeding structure to adapt to beakers 2 of different heights.

[0073] Reference Figure 6 and Figure 7The mixing structure includes a discharge nozzle 30, which is fixedly connected to the bottom of the bottle 20. A sliding plate 31 is slidably connected inside the discharge nozzle 30. Multiple discharge holes 32 are provided inside the sliding plate 31. Multiple slots 33 are provided on the side of the sliding plate 31 that are away from each other. A groove 36 is provided on the inner wall of the side of the discharge nozzle 30 that is away from each other. A wedge-shaped block 35 that mates with the slot 33 is slidably connected inside the groove 36. A first spring 34 is fixedly connected to the end of the wedge-shaped block 35 that is away from the sliding plate 31. One end of the first spring 34 is fixedly connected to the inner wall of one side of the slide 36. By moving the sliding plate 31, the discharge hole 32 can be moved to the center position of the discharge nozzle 30. The cooperation between the slot 33 and the wedge block 35 can position the sliding plate 31. In addition, the amount of indium salt and tin salt added to the beaker 2 at the same time can be controlled by the size of the inner diameter of the discharge hole 32 in the two discharge nozzles 30. Thus, the proportioning can be completed automatically, which is simple and convenient and does not require special personnel to perform the proportioning.

[0074] Reference Figure 6 The inner diameters of the multiple discharge holes 32 increase sequentially, and by controlling the size of the inner diameter of the discharge holes 32 in the two discharge nozzles 30, the ratio of indium salt and tin salt entering the beaker 2 from the two placement bottles 20 can be controlled.

[0075] Reference Figure 10 The stirring plate 14 has a circular hole 41. The inner wall of the circular holes 41 on opposite sides has a triangular groove 42. An extraction rod 43 is installed in the circular hole 41. The extraction rod 43 has a rectangular hole 44. Two wedge plates 45 are slidably connected in the rectangular hole 44 and cooperate with the triangular groove 42. The two wedge plates 45 are elastically connected by multiple second springs 46. After mixing, the semi-circular plate 26 and the splash guard 27 are removed from the top of the beaker 2. The extraction rod 43 is inserted into the circular hole 41. The extraction rod 43 drives the wedge plates 45 to extend into the circular hole 41. Under the elastic force of the second springs 46, the wedge plates 45 extend into the triangular groove 42. At this time, the extraction rod 43 is connected to the stirring plate 14 through the wedge plates 45. The stirring plate 14 can be removed from the beaker 2 by the extraction rod 43, so that the mixed solution in the beaker 2 can proceed to the next process.

[0076] A method of using a pretreatment apparatus for improving the properties of nano-ITO powder includes the following steps:

[0077] S1. First, add water to beaker 2 and start the drive motor 7 to drive the bidirectional lead screw 4, connecting rod 5 and first bevel gear 6 to rotate. The first bevel gear 6 drives the second bevel gear 11 to rotate. The gearbox 10 and the second bevel gear 11 work together to quickly drive the rotating disk 12 to rotate. The rotating disk 12 drives the stirring disk 14 to rotate quickly through the magnetic attraction between the first magnetic block 13 and the second magnetic block 15, which in turn drives the water in beaker 2 to rotate, making it easier to add indium salt and tin salt later.

[0078] S2. According to the ratio of indium salt and tin salt, the sliding plates 31 in the two discharge nozzles 30 are moved respectively. At this time, the height of the two placement bottles 20 is the same. By controlling the size of the discharge hole 32, the capacity of indium salt and tin salt falling from the two placement bottles 20 at the same time can be controlled, so that the required ratio can be automatically completed without manual mixing.

[0079] S3. When the stirring plate 14 rotates, the double-acting screw 4 drives the moving rod 16 to move. The moving rod 16 drives the fixed frame 18 and the placement bottle 20 to move towards the beaker 2. When the two placement bottles 20 approach each other, the two inclined plates 25 touch each other. As the two fixed frames 18 continue to approach each other, the two inclined plates 25 squeeze each other and drive the closing plate 24 and the rotating ring 22 to rotate. The torsion spring 23 begins to store force, and the rotation of the closing plate 24 releases the seal on the discharge nozzle 30. At this time, the indium salt and tin salt contained in the two placement bottles 20 fall down through the discharge nozzle 30.

[0080] S4. Additionally, when the two inclined plates 25 are in contact with each other and rotate, the inclined plates 25 push the anti-splash plate 27 to move outward through the stop block 28, opening the beaker 2. This allows the falling indium and tin salts to enter the beaker 2, ensuring thorough mixing. As the bidirectional lead screw 4 continues to rotate, it drives the fixing frame 18 to move outward. Under the tension of the tension spring 29, the anti-splash plate 27 resets and closes the beaker 2, preventing the solution from splashing out of the beaker 2 when the indium and tin salts are stirred. As the two fixing frames 18 move away from each other, the rotating ring 22 and the closing plate 24 reset and re-close the discharge nozzle 30 under the action of the torsion spring 23. This ensures that the indium and tin salts in the two placement bottles 20 descend at the same time. By controlling the inner diameter of the discharge hole 32 below the two placement bottles 20, the volume of indium and tin salts entering the beaker 2 can be controlled, achieving automatic proportioning.

[0081] S5. As the bidirectional lead screw 4 rotates, it drives the fixed frame 18 to move back and forth, thereby continuously adding the prepared indium and tin salts to the beaker 2 in a timed and quantitative manner. The gradual addition of indium and tin salts allows them to mix thoroughly and quickly in the beaker 2. After mixing, the semi-circular plate 26 and the splash guard 27 are removed from the top of the beaker 2. The extraction rod 43 is inserted into the round hole 41. The extraction rod 43 drives the wedge plate 45 to extend into the round hole 41. Under the elastic force of the second spring 46, the wedge plate 45 extends into the triangular groove 42. At this time, the extraction rod 43 is connected to the stirring plate 14 through the wedge plate 45. The stirring plate 14 can then be removed from the beaker 2 through the extraction rod 43, allowing the mixed solution in the beaker 2 to proceed to the next step.
