[0002] In the ternary precursor production process, the synthesis process is the core process of the entire product production. In the prior art, when synthesizing the ternary precursor, each raw material is generally added to the synthesis reactor, and then the raw materials are dispersed in the slurry in the synthesis reactor in time by stirring, so that each raw material can fully react. However, since the slurry is relatively viscous, when each raw material is added to the synthesis reactor through the feed pipe, the raw materials cannot be dispersed in time and agglomeration occurs. This will change the ratio of the raw materials in the slurry, making it impossible for the raw materials to react well, resulting in a decrease in yield. Utility Model Content

[0005] Furthermore, the first feeding pipe and the second feeding pipe can be multiple, and the first feeding pipe and the second feeding pipe are arranged around the rotating shaft.
[0006] Furthermore, viewed along the axial direction of the rotating shaft, the pipe opening of the first feeding pipe and the pipe opening of the second feeding pipe are respectively located around the first stirring paddle and the second stirring paddle.

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments.
[0019] The utility model provides a synthesis system for avoiding raw material agglomeration. The synthesis system can disperse the raw materials entering the synthesis kettle faster to avoid agglomeration, and can better circulate the slurry in the synthesis kettle to improve the yield of the product.
[0020] Figure 1 The structure diagram of the synthesis system for avoiding raw material agglomeration provided by the embodiment of the utility model is shown. Figure 1 As shown, the synthesis system for avoiding raw material agglomeration provided by the utility model comprises a synthesis reactor 10, a filter tank 20 and a clearing device 30, and the synthesis reactor 10, the filter tank 20 and the clearing device 30 are connected in sequence. A stirring device and a feeding pipe are arranged in the synthesis reactor 10, and the stirring device comprises a rotating shaft 41, a first stirring paddle 42 and a second stirring paddle 43. The rotating shaft 41 extends into the synthesis reactor 10, and the first stirring paddle 42 and the second stirring paddle 43 are arranged on the rotating shaft 41 in sequence from top to bottom. One end of the feeding pipe is fixed to the top of the synthesis reactor 10, and the other end extends downwardly into the synthesis reactor 10 obliquely. On a cross section perpendicular to the rotating shaft 41, the distance from the feeding pipe to the rotating shaft 41 gradually decreases along the up and down direction. That is, the feeding pipe is arranged obliquely from top to bottom in the direction where the rotating shaft 41 is located. The feed pipe includes a first feed pipe 51 and a second feed pipe 52. Both the first feed pipe 51 and the second feed pipe 52 have pipe openings. The pipe opening of the first feed pipe 51 is disposed adjacent to the position of the first stirring paddle 42. Preferably, the pipe opening of the first feed pipe 51 is disposed adjacent to the first stirring paddle 42 and is lower than the height of the first stirring paddle 42 in the synthesis reactor 10. The pipe opening of the second feed pipe 52 is disposed adjacent to the position of the second stirring paddle 43. Preferably, the pipe opening of the second feed pipe 52 is disposed adjacent to the second stirring paddle 43 and is higher than the height of the second stirring paddle 43 in the synthesis reactor 10. That is, the raw material entering the synthesis reactor 10 through the first feed pipe 51 is transported to the lower side of the first stirring paddle 42, while the raw material entering the synthesis reactor 10 through the second feed pipe 52 is transported to the upper side of the second stirring paddle 43.
[0021] In this embodiment, the first feeding pipe 51 and the second feeding pipe 52 are arranged, and the mouth of the first feeding pipe 51 is located below the first stirring paddle 42, and the mouth of the second feeding pipe 52 is located above the second stirring paddle 43. When feeding the raw materials, a part of the raw materials is fed into the synthesis reactor 10 through the first feeding pipe 51. When the raw materials are fed into the synthesis reactor 10, they will be directly fed into the lower part of the first stirring paddle 42, and the first stirring paddle 42 will directly drive the raw materials downward, and disperse the raw materials during the driving process. Another part of the raw materials will be fed into the upper part of the second stirring paddle 43 through the second feeding pipe 52. The raw materials fed into the synthesis reactor 10 by the second feeding pipe 52 will be dispersed by the second stirring paddle 43 on the one hand, and on the other hand, after merging with the raw materials driven downward by the first stirring paddle 42, they will be driven by the second stirring paddle 43 to the edge of the synthesis reactor 10 together with the original slurry, and all the raw materials will be mixed during the driving process. After the mixed raw materials reach the edge of the synthesis reactor 10 , they continue to move upward, and then reach the upper part of the synthesis reactor 10 again, and move downward again under the action of the first stirring paddle 42 to form a complete circulation flow field in the synthesis reactor 10 .
[0022] Therefore, through the arrangement of the above structure, the various raw materials in the synthesis reactor 10 can be dispersed and evenly mixed to avoid raw material agglomeration; and the slurry can be driven to circulate, so that the synthesis reaction proceeds smoothly and the product yield is improved.
[0023] Please continue to refer to Figure 1 In this embodiment, the stirring device also includes a rotating motor 44 and a reducer 45, which are arranged on the top of the synthesis kettle 10 through a support frame, and one end of the rotating shaft 41 is connected to the rotating motor 44 through the reducer 45, and the other end extends into the synthesis kettle 10.
[0024] The first feeding pipe 51 and the second feeding pipe 52 can be multiple, such as two, three or more. The first feeding pipe 51 and the second feeding pipe 52 are arranged around the rotating shaft 41.
[0025] Preferably, viewed along the axis direction of the rotating shaft 41, the openings of the first feeding pipe 51 and the second feeding pipe 52 are respectively located around the first stirring paddle 42 and the second stirring paddle 43. That is, the first feeding pipe 51 does not extend directly below the first stirring paddle 42, and the second feeding pipe 52 does not extend directly above the second stirring paddle 43.
[0026] In the axial direction perpendicular to the rotating shaft 41 , the distance from the pipe opening of the first feeding pipe 51 to the edge of the first stirring paddle 42 , and the distance from the pipe opening of the second feeding pipe 52 to the edge of the second stirring paddle 43 are both D / 120-D / 12, where D is the diameter of the synthesis reactor 10 .
[0027] Furthermore, the first feeding pipe 51 and the second feeding pipe 52 can be fixed to the inner wall of the synthesis reactor 10 through a connecting rod 53 to prevent the two from shaking.
[0028] Figure 2 Shown Figure 1 The enlarged structure diagram of the circle in the middle. Figure 2 As shown, a constricted portion 511 may be formed at the end of the first feeding pipe 51 , that is, the diameter of the end of the first feeding pipe 51 is smaller than the diameter of the middle portion, so as to increase the flow rate of the raw materials entering the synthesis reactor 10 at the end of the first feeding pipe 51 .
[0029] The end of the second feeding tube 52 may be the same as the end of the first feeding tube 51 , and will not be described in detail herein.
[0030] Please continue to refer to Figure 1 In this embodiment, a plurality of baffles 11 are further provided in the synthesis reactor 10 . Each baffle 11 is provided on the inner side wall of the synthesis reactor 10 and extends along the height direction of the synthesis reactor 10 . The plurality of baffles 11 are arranged along the circumference of the synthesis reactor 10 .
[0031] By disposing the baffle plate 11, the circulation flow field around the synthesis reactor 10 can be weakened to facilitate the reaction of various raw materials in the slurry.
[0032] Further, in this embodiment, the lower edge of the baffle plate 11 is lower than the height of the second stirring paddle 43 in the synthesis reactor 10, and the upper edge of the baffle plate 11 is higher than the height of the first stirring paddle 42 in the synthesis reactor 10. Through the above arrangement, the circulation flow field in the synthesis reactor 10 can be optimized to be more conducive to the reaction of each raw material.
[0033] Please continue to see Figure 1 An overflow port 12 is provided at the upper part of the synthesis reactor 10, and a feed port 21 is provided at the upper part of the filter tank 20. The overflow port 12 is connected to the feed port 21 through a connecting pipe 22. As the raw materials are added, the liquid level of the slurry in the synthesis reactor 10 will gradually increase. When the liquid level of the slurry is higher than the height of the overflow port 12, the slurry will flow into the filter tank 20 through the connecting pipe 22. Due to the existence of the circulating flow field, the formed product will be transported to the upper part of the slurry along with the circulating flow field. At this time, the formed product will enter the filter tank 20 for filtration.
[0034] The cleaning device 30 is communicated with the bottom of the filter tank 20 and cleans the slurry flowing into the filter tank 20 to obtain a formed product in the filter tank 20 .
[0035] Furthermore, in this embodiment, the height of the overflow port 12 of the synthesis reactor 10 is higher than the height of the feed port 21 of the filter tank 20 , so that the slurry overflowing from the synthesis reactor 10 can smoothly enter the filter tank 20 .
[0036] A lifting lug 13 is provided in the middle of the synthesis reactor 10. The lifting lug 13 can be used to lift the synthesis reactor 10 to a height higher than the filter tank 20 and ensure the stability of the center of gravity of the synthesis reactor 10 during lifting.
[0037] Furthermore, a jacket (not shown) is provided on the tank body of the synthesis reactor 10, and a heat-insulating liquid is introduced into the jacket to ensure the stability of the temperature inside the tank body.
[0038] In summary, in this embodiment, by separately setting the first feeding pipe 51 and the second feeding pipe 52, and limiting the positions of the first feeding pipe 51 and the second feeding pipe 52 and the first stirring paddle 42 and the second stirring paddle 43, the various raw materials in the synthesis reactor 10 can be dispersed and evenly mixed to avoid raw material agglomeration; and the slurry can be driven to circulate, so that the synthesis reaction proceeds smoothly and the yield of the product is improved. Further, by setting the baffle plate 11, and limiting the positions of the baffle plate 11 and the first stirring paddle 42 and the second stirring paddle 43, the circulation flow field of the slurry in the synthesis reactor 10 can be better optimized, and the yield of the product can be further improved.
