[0032] The utility model will be further explained in detail in combination with the drawings. These drawings are all simplified schematic views, and only illustrate the basic structure of the utility model in a schematic manner, so it only shows the relevant structure of the utility model.
[0033] Embodiment one, as Figures 1 to 3As shown, the embodiment provides a high-precision flow path system, which comprises a premixing member 1. The premixing member 1 is funnel-shaped and hollow inside. The narrow end of the premixing member 1 is the liquid inlet end, and the wide end is the liquid outlet end. The premixing member 1 can be installed inside a closed container, such as a reaction kettle. The solution can pass through the premixing member 1 through the liquid inlet end and the liquid outlet end and be mixed in the reaction kettle. It should be noted that in the prior art, some reactant production processes require placing various solutions in the reaction kettle for thorough mixing. When mixing two or more solutions, there are certain requirements for the order of adding the solutions due to the properties of the solutions to ensure the stability of the components, but this also reduces the overall mixing efficiency. Therefore, in the embodiment, a plurality of liquid inlet openings 17 are formed in the liquid inlet end of the premixing member 1, and at least two liquid inlet openings 17 are provided. At the same time, a premixing mechanism 2 is arranged inside the premixing member 1. When two or more different solutions enter the premixing member 1 through the corresponding liquid inlet openings 17, the solutions will pass through the premixing mechanism 2 and be mixed under the guidance of the premixing mechanism 2, and then be discharged from the liquid outlet end of the premixing member 1. Through this arrangement, the original solution can be divided into two groups, one group needs to be premixed, and the other group does not need to be premixed. The solution that needs to be premixed is introduced into the liquid inlet opening 17, and then the solution is guided by the premixing mechanism 2 to be premixed, and is synchronized with the other group of solutions to pass through the premixing member 1, thereby greatly reducing the loss of mixing efficiency caused by the need to add multiple solutions in sequence.
[0034] To achieve the above effects, in the embodiment, as a preferred, the premixing mechanism 2 comprises a support sleeve 21, a flow guide assembly and a mixing assembly. A through hole is formed at the position of the shaft center of the premixing member 1 for the convenience of inserting the shaft. The support sleeve 21 is coaxially arranged with the premixing member 1, and the support sleeve 21 penetrates the premixing member 1 along the thickness direction. The flow guide assembly is installed on the support sleeve 21, and the mixing assembly is installed on the inner wall of the premixing member 1. The flow guide assembly extends radially from inside to outside, and the mixing assembly extends radially from outside to inside. The flow guide assembly and the mixing assembly are staggered, thereby forming a continuous and zigzag channel, i.e., a mixing flow path, between the flow guide assembly and the mixing assembly. When the solution passes through the flow guide assembly and the mixing assembly, it will be repeatedly blocked and changed direction, thereby achieving the effect of thoroughly mixing multiple solutions.
[0035] To accelerate the flow speed of the solution, in the embodiment, as an option, the flow guide assembly is inclined downward in the direction away from the shaft center, and the mixing assembly is inclined downward in the direction close to the shaft center.
[0036] The structure of the drainage assembly is described below. The drainage assembly includes a first drainage ring 221, a second drainage ring 222, and a third drainage ring 223, which are arranged at equal intervals along the axial direction of the support sleeve 21. Since the premixing member 1 is funnel-shaped, the diameters of the first drainage ring 221, the second drainage ring 222, and the third drainage ring 223 are increased in sequence in this embodiment to prolong the residence time of the solution on the drainage assembly, thereby improving the mixing effect. The mixing assembly includes a first mixing ring 231, a second mixing ring 232, and a third mixing ring 233, which are arranged at equal intervals along the inner wall of the premixing member 1 in the axial direction. The inner diameters of the first mixing ring 231, the second mixing ring 232, and the third mixing ring 233 are equal. The first mixing ring 231 is arranged between the first drainage ring 221 and the second drainage ring 222, the second mixing ring 232 is arranged between the second drainage ring 222 and the third drainage ring 223, and the third mixing ring 233 is arranged at the bottom of the premixing member 1. Through the above arrangement, the time of the solution in the mixing flow path can be prolonged, thereby improving the mixing effect of the solution.
[0037] In order to further make the solution that does not need to be mixed pass through the premixing member 1 synchronously with the solution that needs to be mixed, in the embodiment, as a preference, the outer side of the premixing member 1 is provided with a compensation assembly 11, the compensation assembly 11 comprises a first compensation ring 111, a second compensation ring 112 and a third compensation ring 113, the first compensation ring 111, the second compensation ring 112 and the third compensation ring 113 are arranged equidistantly along the outer wall of the premixing member 1. The inner side of the first compensation ring 111 is provided with a first flow-through hole 12, the inner side of the second compensation ring 112 is provided with a second flow-through hole 13, and the inner side of the third compensation ring 113 is provided with a third flow-through hole 14. Through the above arrangement, when the solution passes to the outer side of the premixing member 1, it flows on the first compensation ring 111, passes through the first flow-through hole 12 into the second compensation ring 112, flows along the second compensation ring 112, passes through the second flow-through hole 13 into the third compensation ring 113, and finally flows out through the third flow-through hole 14. By guiding the solution to flow through the first compensation ring 111, the second compensation ring 112 and the third compensation ring 113 in sequence, the travel of the solution passing through the premixing mechanism 2 is compensated, so as to realize the effect that the solutions on the inner and outer sides of the premixing member 1 pass through the premixing member 1 synchronously. In addition, in order to prolong the time of the solution on the first compensation ring 111, the second compensation ring 112 and the third compensation ring 113 as much as possible, the second flow-through hole 13 is arranged on the side away from the first flow-through hole 12, and the third flow-through hole 14 is arranged on the side away from the second flow-through hole 13.
[0038] In order to make the solution on the outer side of the premixing member 1 pass through the premixing member 1, in the embodiment, the bottom of the premixing member 1 is provided with an assembly ring 15, and a plurality of conveying holes 16 are uniformly arranged on the assembly ring 15 in the circumferential direction. After the solution passes through the third flow-through hole 14, it falls on the assembly ring 15 and then passes through the premixing member 1 through the conveying holes 16.
