[0032] The following further elaborates on the embodiments of the present utility model with reference to the accompanying drawings.
[0033] According to some embodiments of the present utility model, refer to Figures 1 to 4 , the non-stirring high-efficiency dispersion reaction device includes a reaction kettle 100, a guiding component 200, and a circulation component 300. The reaction kettle 100 is provided with a feeding pipe 110 and a discharging pipe 120, and the feeding pipe 110 and the discharging pipe 120 are respectively communicated with the inner cavity of the reaction kettle 100. The guiding component 200 is arranged in the reaction kettle 100. The guiding component 200 includes a plurality of spiral plates 210. The plurality of spiral plates 210 spiral upward in the same direction. The plurality of spiral plates 210 are circumferentially distributed along the axis of the reaction kettle 100, and the axial direction of the reaction kettle 100 is the up-and-down direction. In the horizontal projection plane, the spiral plate 210 is arc-shaped. The plurality of spiral plates 210 are sequentially connected end to end to form a circle. The low end of one spiral plate 210 coincides with the high end of an adjacent spiral plate 210. In this embodiment, there are four spiral plates 210, and the four spiral plates 210 all spiral upward in the clockwise direction. In the horizontal projection plane, the four spiral plates 210 are sequentially connected end to end to form a circle, and the center of the circle is located on the axis of the reaction kettle 100. Each spiral plate 210 forms a quarter of a circle. In other embodiments, the plurality of spiral plates 210 may also spiral upward in the counterclockwise direction.
[0034] Refer to Figure 1 and Figure 4, the circulation component 300 includes a circulation feed pipe 310, a circulation discharge pipe 320, and a circulation driving component 330. The circulation feed pipe 310 is lower than the circulation discharge pipe 320. The discharge end of the circulation driving component 330 is connected to the circulation feed pipe 310, and the suction end of the circulation driving component 330 is connected to the circulation discharge pipe 320. The circulation feed pipe 310 is provided with a plurality of feed branch pipes 311, and the feed branch pipes 311 are arranged in the reaction kettle 100. The plurality of feed branch pipes 311 correspond to the plurality of spiral plates 210 one by one. The feed branch pipes 311 are located at the lower end of the spiral plate 210 and the discharge direction thereof is the spiral direction of the spiral plate. The suction end of the circulation discharge pipe 320 is arranged in the reaction kettle 100. In this embodiment, the circulation feed pipe 310 is annular and sleeved on the guiding component 200. The inner side of the circulation feed pipe 310 is connected to one end of the four feed branch pipes 311. The four feed branch pipes 311 are circumferentially distributed around the axis of the reaction kettle 100, and the feed branch pipes 311 are located on the upper surface of the lower end of the spiral plate 210.
[0035] After the slurry enters the reaction kettle 100 from the feeding pipe 110, under the action of the circulation driving component 330, the circulation discharge pipe 320 sucks the slurry in the reaction kettle 100 and transfers the slurry to the circulation feed pipe 310. The slurry in the circulation feed pipe 310 is shunted into a plurality of feed branch pipes 311. The slurry flowing out of the feed branch pipes 311 enters the inner cavity of the reaction kettle 100 and falls on the spiral plate 210. The slurry moves upward along the spiral rising direction of the spiral plate 210. The spiral plate 210 guides the slurry to spiral upward, so that the slurry in the reaction kettle 100 still rotates spontaneously without being stirred, so that the slurry can be fully dispersed. The slurry is then sucked by the circulation discharge pipe 320 again and re-enters the circulation feed pipe 310. In this way, the slurry is finally discharged through the discharge pipe 120. This non-stirring high-efficiency dispersion reaction device solves the problem that the mixing shaft is worn and metal foreign matters are mixed into the slurry.
[0036] Further, referring to Figure 4, the circulating discharge pipe 320 is provided with a plurality of discharge branch pipes 321, and the plurality of discharge branch pipes 321 correspond to the plurality of spiral plates 210 one by one. The discharge branch pipes 321 are higher than the feed branch pipes 311, and the suction ends of the discharge branch pipes 321 are located in the middle of the spiral plate 210 and below the lower surface of the spiral plate 210. In this embodiment, the circulating discharge pipe 320 is annular and sleeved on the guiding assembly 200. The inner side of the circulating discharge pipe 320 is connected to one end of the four discharge branch pipes 321. The four discharge branch pipes 321 are circumferentially distributed around the axis of the reaction kettle 100. The other end of the discharge branch pipe 321 is located in the middle of the spiral plate 210 and below the lower surface of the spiral plate 210. When the slurry moves upward along the spiral plate 210, the discharge branch pipe 321 can continue to apply suction to the slurry to suck the slurry, avoiding blocking the feed branch pipe 311 from continuing to discharge the slurry, ensuring that the slurry can have sufficient power. At the same time, when the slurry rises to the highest point along the spiral plate 210, the discharge branch pipe 321 provides suction to the slurry to accelerate the downward movement of the slurry, so that the slurry can perform a swirling shear motion in the reaction kettle 100.
[0037] It should be noted that the circulating discharge pipe 320 and the circulating feed pipe 310 can be located inside the reaction kettle 100 or outside the reaction kettle 100. When both the circulating discharge pipe 320 and the circulating feed pipe 310 are located outside the reaction kettle 100, it can avoid occupying the volume of the reaction kettle 100 and increase the slurry capacity in the reaction kettle 100. At this time, one end of the discharge branch pipe 321 and one end of the feed branch pipe 311 both penetrate through the reaction kettle 100 to insert into the inner cavity of the reaction kettle 100.
[0038] Furthermore, the discharge end of the feed branch pipe 311 is located on the upper surface of the spiral plate 210, and at least part of the slurry sprayed by the feed branch pipe 311 spirally moves upward along the upper surface of the spiral plate 210 to ensure that the slurry in the reaction kettle 100 can rotate spontaneously as a whole.
[0039] In this embodiment, the circulating discharge pipe 320 is located above the circulating feed pipe 310.
[0040] Furthermore, referring to Figure 4 , one end of the feed branch pipe 311 is connected to the circulating feed pipe 310, and the other end of the feed branch pipe 311 is provided with a spraying part 312. The diameter of the spraying part 312 gradually decreases along its outlet direction. By reducing the diameter, the flow rate of the slurry is increased, and the initial power of the slurry entering the spiral plate 210 is improved to ensure that the slurry has sufficient power to spiral upward.
[0041] According to some embodiments of the present invention, referring to Figure 1, there are multiple zirconium beads 101 in the reactor 100. The zirconium beads 101 are used to disperse and grind the slurry. The zirconium beads 101 account for 5% - 10% of the volume of the reactor 100. The zirconium beads 101 can perform a swirling motion together with the slurry to further evenly disperse the slurry and reduce the agglomeration of the precursor. Further, the discharge pipe 120 is provided with a filter screen to block the zirconium beads 101 and prevent the zirconium beads 101 from leaving the reactor 100 with the slurry through the discharge pipe 120. The filter screen is detachably connected for easy cleaning and replacement, and it is also convenient to replace the zirconium beads 101. The discharge pipe 120 is located in the middle of the bottom of the reactor 100 for easy discharge of the slurry.
[0042] Further, referring to Figure 1 , the reactor 100 is provided with an overflow pipe 130. The overflow pipe 130 is located at the upper end of the side wall of the reactor 100. When there is too much slurry in the reactor 100, the slurry is discharged through the overflow pipe 130 to avoid excessive pressure in the reactor 100. Preferably, a filter screen is provided at the overflow pipe 130 to prevent the zirconium beads 101 from leaving the reactor 100 with the slurry through the overflow pipe 130. The filter screen is detachably connected for easy cleaning and replacement, and it is also convenient to replace the zirconium beads 101.
[0043] It should be noted that the overflow pipe 130 is located on the side wall of the reactor 100, while the discharge pipe 120 is located at the bottom of the reactor 100, so that the reactor 100 can be used for continuous and batch methods to synthesize the precursor.
[0044] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 , the circulation driving component 330 includes a circulation feed pump 340, a circulation discharge pump 350, and a circulation tank 360. The discharge end of the circulation feed pump 340 is connected to the circulation feed pipe 310, the feed end of the circulation feed pump 340 is connected to the circulation tank 360, the feed end of the circulation discharge pump 350 is connected to the circulation discharge pipe 320, and the discharge end of the circulation discharge pump 350 is connected to the circulation tank 360. The combined cooperation of the circulation feed pump 340 and the circulation discharge pump 350 can provide sufficient power for the slurry to ensure that the slurry can perform a swirling motion in the reactor 100. The circulation tank 360 can match the circulation in and out volume to avoid interference caused by directly connecting the circulation discharge pump 350 and the circulation feed pump 340 through pipelines. Further, the circulation tank 360 is provided with a feeding port 361. Through the feeding port 361, materials such as additives can be put into the circulation tank 360, and samples can also be taken from the circulation tank 360 through the feeding port 361.
[0045] It should be noted that the circulation tank 360 can also be a concentrator, which can be better adapted to synthetic precursor routes such as continuous method, batch method, and batch method - concentration.
[0046] Further, referring to Figure 1, the reaction kettle 100 is provided with a plurality of feeding pipes 110. The plurality of feeding pipes 110 are arranged at intervals in the left-right direction, and the number of the feeding pipes 110 can be adjusted according to requirements. The feeding pipes 110 are located at the top of the reaction kettle 100. Through the plurality of feeding pipes 110, a variety of materials can be added into the reaction kettle 100 simultaneously, improving the efficiency.
