[0029] As shown in Figure 1 The reaction device provided by the present application, and embodiments of the reaction device of the present application include: a reaction kettle 10, a feeding structure 20, the reaction kettle 10 has a reaction cavity 11; the feeding structure 20 includes a feeding main body 21 and a distribution part 22 which are communicated, the feeding main body 21 is arranged outside the reaction cavity 11, the distribution part 22 is arranged in the reaction cavity 11 and is detachably connected with the reaction kettle 10, and the distribution part 22 includes a first annular distribution pipe 221 and a second annular distribution pipe 222 which are arranged at intervals.
[0030] According to the technical scheme in the embodiment, the reaction kettle 10 provides a mounting base for other structures of the reaction device, and the reaction kettle 10 has a reaction cavity 11 in which the reaction occurs. The feeding structure 20 includes a feeding body 21 and a distribution part 22 which are in communication. The feeding body 21 is arranged outside the reaction cavity 11, and the feeding structure 20 is used to deliver the reaction materials into the reaction cavity 11. The distribution part 22 is arranged in the reaction cavity 11 and detachably connected to the reaction kettle 10. The detachable distribution part 22 is convenient for the staff to adjust according to the specific needs of the reaction, so that the distribution part 22 meets different distribution requirements. The distribution part 22 includes first and second annular distribution pipes 221 and 222 which are arranged at intervals. Compared with the related art, the embodiment provides more distribution structures, so that the reaction materials can be more uniformly distributed in the reaction cavity 11, thereby avoiding the situation that the local concentration of the reaction cavity 11 is too high, reducing the possibility of agglomeration, and thereby reducing the possibility of generating too many impurities in the reaction. Therefore, the technical scheme in the embodiment can effectively solve the problem of too many impurities generated in the related art.
[0031] It should be noted that the shapes formed by the first and second annular distribution pipes 221 and 222 are not limited to circular shapes, but can also be oval, polygonal or other special shapes. The first and second annular distribution pipes 221 and 222 are not limited to being arranged at intervals in the inner-outer direction, but can also be arranged at intervals in other ways, such as side-by-side.
[0032] As shown in Figure 1 The feeding structure 20 further includes a communication pipe 23, a first distribution pipe 24 and a second distribution pipe 25. The communication pipe 23 is arranged on the reaction kettle 10, the first end of the communication pipe 23 is in communication with the feeding body 21, the second end of the communication pipe 23 is in communication with the first and second distribution pipes 24 and 25 respectively, the first distribution pipe 24 is in communication with the first annular distribution pipe 221, and the second distribution pipe 25 is in communication with the second annular distribution pipe 222. Specifically, the first and second distribution pipes 24 and 25 are arranged to allow the reaction materials to enter the first and second annular distribution pipes 221 and 222 respectively, so that the reaction materials can be uniformly distributed.
[0033] As shown in Figure 2 and Figure 3As shown, the first annular distribution pipe 221 is provided with a plurality of first discharging members 223, and the discharging direction of the plurality of first discharging members 223 is arranged at an angle with the vertical direction. Specifically, in the embodiment, the first discharging member 223 is a drainage tube in a tubular structure, and the axial direction of the drainage tube is the discharging direction of the first discharging member 223. The drainage tube is arranged obliquely relative to the vertical direction, so that the discharging direction of the first discharging member 223 is arranged at an angle with the vertical direction, and the discharging direction of the first discharging member 223 can be controlled as needed by the worker, so that the discharging direction is more flexible and can better meet the design needs and ensure the uniformity of the reaction.
[0034] As shown in Figure 2 and Figure 3 In the adjacent two first discharging members 223, one first discharging member 223 is arranged obliquely inward, and the other first discharging member 223 is arranged obliquely outward. Specifically, such arrangement can make the discharging more uniform and avoid the situation that the local concentration of the material in the same direction is too high due to the oblique arrangement of the first discharging member 223 in the same direction.
[0035] In addition, in the embodiment, the angle between the discharging direction of the first discharging member 223 and the vertical direction is greater than or equal to 0 and less than or equal to 45°. Specifically, the worker can adjust the inclination angle of the first discharging member 223 as needed, and it is not necessary to make the inclination angle of each first discharging member 223 consistent, which enhances the flexibility of the arrangement of the first discharging member 223. The angle between the discharging direction of the first discharging member 223 and the vertical direction can be 0, 5°, 10°, 18°, 23°, 37°, 41° or 45°. It should be noted that when the angle between the discharging direction of the first discharging member 223 and the vertical direction is 0, it means that the discharging direction of the first discharging member 223 is parallel to the vertical direction, which is also a case that satisfies "the discharging direction of the plurality of first discharging members 223 is arranged at an angle with the vertical direction".
[0036] In addition, the first annular distribution pipe 221 includes a plurality of sub-ring segments that are connected and detachably arranged. Such arrangement can make the first annular distribution pipe 221 easier to be cleaned, and the worker can combine the sub-ring segments as needed to form a first annular distribution pipe with different structures.
[0037] Furthermore, in this embodiment, the number of first discharge components 223 is greater than or equal to 40 and less than or equal to 200. Specifically, the first discharge components 223 that meet the above requirements ensure that there are enough discharge points for the reactants, resulting in a sufficiently large coverage area, while also keeping the number of these discharge points within a suitable range, thereby controlling processing costs. The number of first discharge components 223 can be 40, 68, 89, 100, 136, 174, or 200.
[0038] In other embodiments, the first discharge element includes a discharge hole disposed on the first annular feeding tube, and the diameter of the discharge hole is greater than or equal to 0.5 mm and less than or equal to 8 mm. Specifically, this arrangement allows control over the amount of material fed through each discharge hole per unit time, keeping it within a suitable range. Specifically, the diameter of the discharge hole can be 0.5 mm, 1.5 mm, 2 mm, 3.3 mm, 4.6 mm, 6.8 mm, 7.7 mm, or 8 mm.
[0039] like Figure 1 As shown, the first annular feeding tube 221 is located outside the second annular feeding tube 222 in the circumferential direction. The second annular feeding tube 222 is equipped with multiple second discharge elements, and the ratio of the number of second discharge elements to the number of first discharge elements 223 is greater than or equal to 1:5 and less than or equal to 1:2. With this arrangement, since the second annular feeding tube 222 is located on the inner side and its length is shorter than that of the first annular feeding tube 221, appropriately reducing the number of second discharge elements can prevent the material concentration in the inner region of the reaction chamber from becoming too high, thereby avoiding "agglomeration." The ratio of the number of second discharge elements to the number of first discharge elements 223 can be 1:5, 1:4.2, 1:3.5, 1:3, or 1:2.
[0040] Furthermore, both the first annular feeding tube 221 and the second annular feeding tube 222 are circular tube structures. The ratio of the diameter of the cross-section of the second annular feeding tube 222 to the diameter of the cross-section of the first annular feeding tube 221 is greater than or equal to 1:2 and less than or equal to 4:5. With this configuration, since the area covered by the second annular feeding tube 222 is smaller than that of the first annular feeding tube 221, the amount of reactant material required to be distributed by the second annular feeding tube 222 per unit time is less. Making the second annular feeding tube 222 thinner can meet the above requirements. The ratio of the diameter of the cross-section of the second annular feeding tube 222 to the diameter of the cross-section of the first annular feeding tube 221 can be 1:2, 3:5, 7:10, or 4:5.
[0041] like Figure 1As shown, the reaction device further comprises a blowing part 30, which is arranged in communication with the feeding main body 21. Specifically, after the delivery of the reaction material is completed each time, compressed air is used to blow the reaction material possibly remaining in the feeding structure 20 into the reaction cavity 11, so as to ensure the smoothness of the feeding structure 20.
[0042] As shown in the drawings, Figure 1 As shown, the feeding structure 20 further comprises a first valve body 26 and a second valve body 27, the first valve body 26 is arranged on the first distribution pipe 24, and the second valve body 27 is arranged on the second distribution pipe 25. In this way, the staff can adjust the flow in the first annular distribution pipe 221 and the second annular distribution pipe 222 according to the needs, so as to adjust the uniformity of the distribution.
[0043] As shown in the drawings, Figure 4 As shown, the reaction device further comprises a connecting structure 40, which comprises a base body 41, a first clamping section 42, a second clamping section 43 and a stop block 44. The base body 41 is connected with the inner wall surface of the reaction cavity 11. The first end of the first clamping section 42 is hinged with the base body 41. The second end of the first clamping section 42 is hinged with the first end of the second clamping section 43. The stop block 44 is rotatably arranged at the second end of the second clamping section 43. The base body 41 is provided with an insertion hole 45. When the connecting structure 40 is in a clamping state, the first clamping section 42 and the second clamping section 43 clamp the first annular distribution pipe 221. The stop block 44 passes through the insertion hole 45 and is in abutting engagement with the base body 41, so that the connecting structure 40 remains in the clamping state. Specifically, the first clamping section 42 and the second clamping section 43 are made of metal with certain deformation ability. The insertion hole 45 is a rectangular hole. The stop block 44 is a rectangular block matched with the insertion hole 45. After the stop block 44 passes through the insertion hole 45, the stop block 44 is rotated to abut against the surface of the base body 41, so that the stop block 44 cannot be taken out of the insertion hole 45, and the connecting structure 40 remains in the clamping state. In this way, the staff can dismount the first annular distribution pipe 221 and the second annular distribution pipe 222, so that the reaction device can meet different reaction requirements.
[0044] The embodiment can be used as a lithium salt preparation lithium precipitation distributor device. The device is mainly used for mixing lithium sulfate solution and sodium carbonate solution, strengthening stirring and enhancing lithium precipitation uniformity. The reaction device of the embodiment can improve the uniformity of the distribution of the reaction material. The multi-pipe feeding mode can increase the feeding amount and the feeding flow rate, improve the reaction turbulence, increase the reaction contact area, and thus ensure that the mixing process is more uniform and sufficient.
[0045] As a key link in the process of preparing lithium salt from lithium-containing ore, the distributor can achieve the following effects in the distribution process:
[0046] 1. The reaction device improves the mixing efficiency of lithium sulfate solution and sodium carbonate solution, increases the processing capacity, and has no agglomeration and walling phenomenon after mixing;
[0047] 2. The reaction device has long service life and will not cause internal walling to affect equipment operation.
