Description

Technical Field

[0001] The utility model relates to a stirring assembly, in particular to a stirring assembly for a cooling crystallization device applied to the field of cooling crystallization equipment. Background Art

[0002] Black titanium liquid is an important chemical raw material, widely used in fields such as titanium dioxide, titanium alloy, and titanate. It belongs to a special solution with special properties. For example, it may undergo hydrolysis when diluted or heated for a long time. And to avoid hydrolysis, its concentration must be carried out by low-temperature evaporation under vacuum. During the use and production process of black titanium liquid, a cooling crystallization device is needed to cool it down.

[0003] When using a cooling crystallization device to cool black titanium liquid, a stirring assembly is used to stir the black titanium liquid evenly. The existing cooling crystallization devices generally cool the cooling tank externally, causing the temperature of the black titanium liquid inside the cooling tank to drop and freeze. However, during the stirring process, the temperature of the black titanium liquid at the inner wall of the cooling tank is uneven with that of the inner black titanium liquid, resulting in ice formation on the inner wall of the cooling tank while the inner black titanium liquid has not crystallized yet, thus reducing the cooling effect of the black titanium liquid. Content of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that the stirring effect of the stirring assembly is not good, resulting in uneven temperature inside and outside the black titanium liquid, causing ice formation on the inner wall of the cooling tank while the inner black titanium liquid has not crystallized yet, and reducing the cooling effect of the black titanium liquid.

[0005] To solve the above problems, the utility model provides a stirring assembly for a cooling crystallization device, including a fixed shaft. An electric motor is provided at the upper end of the fixed shaft. A plurality of scraping rods are fixedly connected to the outer surface of the fixed shaft. An adjusting assembly is provided at the lower end of the fixed shaft. The adjusting assembly includes a waterproof box and two driving bevel gears located inside the waterproof box. The waterproof box is fixedly sleeved on the outer surface of the fixed shaft. The corresponding ends of the two driving bevel gears are jointly engaged with two driven bevel gears. The remote ends of the two driven bevel gears are respectively fixedly connected with mounting rods. The remote ends of the two mounting rods are respectively rotatably connected to the left and right inner walls of the waterproof box. A positioning shaft is provided at the lower end of the waterproof box. The upper end of the positioning shaft rotatably penetrates into the waterproof box. The remote ends of the two driving bevel gears are respectively fixedly connected to the fixed shaft and the positioning shaft. A stirring belt is fixedly sleeved on the outer surface of the positioning shaft. A plurality of stirring rods are also fixedly connected to the outer surface of the positioning shaft.

[0006] In the stirring assembly for the above cooling crystallization equipment, during the stirring process, the inner wall of the cooling tank can be scraped, and the scraping rod and the stirring rod rotate in different directions, thereby improving the stirring effect, effectively cooling the black titanium liquid evenly, preventing the black titanium liquid from crystallizing and precipitating, and improving the cooling effect.

[0007] As a further improvement of the present application, the output end of the motor is fixedly connected to the upper end of the fixed shaft, and a plurality of scraping rods are distributed in a circular array around the central axis of the fixed shaft.

[0008] As a further improvement of the present application, the longitudinal section of the scraping rod is triangular, and the scraping rod is integrally U-shaped.

[0009] As a further improvement of the present application, the stirring belt is spiral, a plurality of stirring rods are staggered, and the stirring rods do not contact the stirring belt and the scraping rod.

[0010] As another improvement of the present application, the adjusting assembly is replaced with a synchronization assembly. The synchronization assembly includes a central shaft fixedly connected to the upper end of the positioning shaft. The upper end of the central shaft rotates through the fixed shaft. The output end of the motor is fixedly connected with an adjusting rod. A pulley group is sleeved on the outer surfaces of the adjusting rod and the fixed shaft together. The upper end of the adjusting rod is fixedly connected with a driving spur gear. A driven spur gear is fixedly sleeved on the outer ring of the central shaft. The driving spur gear and the driven spur gear are meshed with each other.

[0011] As a supplement to another improvement of the present application, the pulley group includes two fixed wheels and a belt movably sleeved on the outer surfaces of the two fixed wheels. One fixed wheel is fixedly sleeved on the outer surface of the fixed shaft, and the other fixed wheel is fixedly sleeved on the outer surface of the adjusting rod.

[0012] In summary, during the actual application process, the motor drives the fixed shaft to rotate, so that the scraping rod rotates, and the scraping rod scrapes the inner wall of the cooling tank, thereby effectively avoiding the phenomenon of ice formation on the inner wall of the cooling tank. At the same time, the upper driving bevel gear drives the two driven bevel gears to rotate, so that the lower driving bevel gear rotates reversely, thereby driving the positioning shaft and the fixed shaft to rotate in opposite directions, and enabling the stirring belt and the stirring rod to rotate in opposite directions at the same time, so as to stir the black titanium liquid in multiple directions, effectively improving the uniformity of stirring, effectively preventing the black titanium liquid from crystallizing and precipitating, and improving the cooling effect.

[0021] The following will describe in detail the two embodiments of the present application with reference to the accompanying drawings.

[0022] The first embodiment:

[0023] Figure 1 and Figure 2 shows: A stirring assembly for a cooling crystallization device, including a fixed shaft 1, with a motor 10 provided at the upper end of the fixed shaft 1. Those skilled in the art can select a suitable model of the motor 10 according to actual needs. For example: Y2 - 63M1 - 2 - 0.18KW. A plurality of scraping rods 2 are fixedly connected to the outer surface of the fixed shaft 1. An adjusting assembly is provided at the lower end of the fixed shaft 1. The output end of the motor 10 is fixedly connected to the upper end of the fixed shaft 1. The plurality of scraping rods 2 are distributed in a circular array around the central axis of the fixed shaft 1. The longitudinal section of the scraping rod 2 is triangular, and the scraping rod 2 is integrally U-shaped. The scraping rod 2 can scrape the inner wall of the cooling tank while stirring the black titanium liquid, thereby effectively avoiding the phenomenon of ice formation on the inner wall of the cooling tank.

[0024] Figure 3 and Figure 4It shows that the adjusting component includes a waterproof box 3 and two driving bevel gears 4 located inside the waterproof box 3. The waterproof box 3 is fixedly sleeved on the outer surface of the fixed shaft 1. One end of the two driving bevel gears 4 corresponding to each other is jointly engaged with two driven bevel gears 5. One end of the two driven bevel gears 5 away from each other is fixedly connected with a mounting rod 6. One end of the two mounting rods 6 away from each other is respectively rotatably connected to the left and right inner walls of the waterproof box 3. A positioning shaft 7 is provided at the lower end of the waterproof box 3. The upper end of the positioning shaft 7 rotatably penetrates into the waterproof box 3. One end of the two driving bevel gears 4 away from each other is respectively fixedly connected to the fixed shaft 1 and the positioning shaft 7. When the driving bevel gear 4 connected to the fixed shaft 1 rotates, it can drive the rotation of the two driven bevel gears 5, thereby driving the driving bevel gear 4 connected to the positioning shaft 7 to rotate in the reverse direction, and further causing the positioning shaft 7 and the fixed shaft 1 to rotate in opposite directions. A stirring belt 8 is fixedly sleeved on the outer surface of the positioning shaft 7. A plurality of stirring rods 9 are also fixedly connected to the outer surface of the positioning shaft 7. The stirring belt 8 is spiral. The plurality of stirring rods 9 are staggered, and the stirring rods 9 do not contact the stirring belt 8 and the scraping rod 2. The stirring rods 9 and the stirring belt 8 perform multiple stirrings on the inside of the black titanium liquid, improving the stirring efficiency.

[0025] During use, the motor 10 drives the fixed shaft 1 to rotate, so that the scraping rod 2 rotates, and the scraping rod 2 scrapes the inner wall of the cooling tank, effectively avoiding the phenomenon of ice formation on the inner wall of the cooling tank. At the same time, the upper driving bevel gear 4 drives the two driven bevel gears 5 to rotate, so that the lower driving bevel gear 4 rotates in the reverse direction, driving the positioning shaft 7 and the fixed shaft 1 to rotate in opposite directions, making the stirring belt 8 and the stirring rods 9 rotate in the opposite direction at the same time, thereby stirring the black titanium liquid in all directions, effectively improving the uniformity of stirring, effectively preventing the black titanium liquid from crystallizing and precipitating, and improving the cooling effect.

[0026] The second implementation mode:

[0027] Based on the first implementation mode, in this implementation mode, the adjusting component is replaced with a synchronous component, and the rest is the same as the first implementation mode.

[0028] Figure 5 and Figure 6It is shown that the adjustment component is replaced with a synchronization component. The synchronization component includes a central shaft 11 fixedly connected to the upper end of the positioning shaft 7. The upper end of the central shaft 11 rotatably penetrates through the fixed shaft 1. The output end of the motor 10 is fixedly connected with an adjustment rod 12. A pulley group 13 is sleeved on the outer surfaces of the adjustment rod 12 and the fixed shaft 1 together. The upper end of the adjustment rod 12 is fixedly connected with a driving spur gear 14. A driven spur gear 15 is fixedly sleeved on the outer circle of the central shaft 11. The driving spur gear 14 and the driven spur gear 15 are meshed with each other. The pulley group 13 includes two fixed pulleys and a belt movably sleeved on the outer surfaces of the two fixed pulleys. One fixed pulley is fixedly sleeved on the outer surface of the fixed shaft 1, and the other fixed pulley is fixedly sleeved on the outer surface of the adjustment rod 12.

[0029] During use, when the motor 10 starts, it can drive the rotation of the fixed pulley and the driving spur gear 14. The fixed pulley drives the rotation of the other fixed pulley through the belt, and the driving spur gear 14 can drive the rotation of the driven spur gear 15, so that the fixed shaft 1 and the central shaft 11 rotate in opposite directions at the same time, and then drive the scraping rod 2 and the positioning shaft 7 to rotate in different directions, so that the stirring rod 9, the scraping rod 2 and the stirring belt 8 stir the black titanium liquid, promoting the cooling and crystallization of the black titanium liquid.

[0030] It should be noted that the rotation control between the fixed shaft 1 and the positioning shaft 7 is not limited to the two types mentioned in the two embodiments. Any other method that can drive the fixed shaft 1 and the positioning shaft 7 to rotate in opposite directions at the same time is acceptable.

[0031] Combined with the current actual needs, the above-mentioned embodiments adopted in this application, the protection scope is not limited thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
