Technical Field

[0001] The utility model relates to the field of liquid-phase mixing equipment, and more specifically, to a liquid-phase feed distributor. Background Art

[0002] In a reaction vessel in the field of chemical production, through liquid-phase feeding, there is a reaction liquid-phase catalyst stored in the kettle, and two or more liquid-phase materials react completely to obtain a reaction product.

In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present disclosure.

[0024] Example 1

[0025] As Figure 1 and Figure 2 , a liquid-phase feed distributor includes a reaction vessel 1, a mixing mechanism 2, a connecting pipe 3, and a nozzle 4. The mixing mechanism 2 is installed inside the reaction vessel 1. The connecting pipe 3 and the nozzle 4 are detachably connected to the side of the reaction vessel 1 through bolt fasteners. The connecting pipe 3 is at least a three-way structure, one end of which is communicated with the mixing mechanism 2, and the other two ends are communicated with a pump. The liquid phase enters the mixing mechanism 2 through the ports of the corresponding connecting pipe 3 under the action of the corresponding pump, and is mixed by the mixing mechanism 2. The different liquid phases will fall into the reaction vessel 1 after mixing. The nozzle 4 can be opened when necessary to discharge the liquid phase that has been mixed and stored in the reaction vessel 1.

[0026] It can be known that by changing the structure of the three-way, the liquid phase from the outside can enter the reaction vessel 1, and the liquid phase in the reaction vessel 1 can also be continuously extracted for repeated mixing to improve the mixing rate.

[0027] Among them, the mixing mechanism 2 includes a distribution pipe 21, through holes 22 and a cover plate 23. The distribution pipe 21 is either fixedly or detachably connected to the inner wall of the reaction vessel 1. The distribution pipe 21 communicates with the connecting pipe 3. A number of through holes 22 are formed above the distribution pipe 21. A cover plate 23 is fixed on the inner wall of the reaction vessel 1 and is spaced directly above the through holes 22. Under the pressure action of the pump, after different liquid phases enter the distribution pipe 21, they will be ejected through the through holes 22, and after hitting the cover plate 23, they will be dispersed. The frequency of mutual contact between the dispersed different liquid phases is increased, and the mixing degree between different liquid phases can be improved.

[0028] Example 2

[0029] Such as Figure 3 and Figure 4 A liquid-phase feed distributor includes a reaction vessel 1, a mixing mechanism 2, a connecting pipe 3 and a nozzle 4. A mixing mechanism 2 is installed in the reaction vessel 1. A connecting pipe 3 and a nozzle 4 are detachably connected to the side of the reaction vessel 1 through bolt fasteners respectively. The connecting pipe 3 is at least a three-way structure, one end of which communicates with the mixing mechanism 2, and the other two ends communicate with the pump. The liquid phase enters the mixing mechanism 2 through the ports of the corresponding connecting pipe 3 under the action of the corresponding pump, and is mixed by the mixing mechanism 2. After different liquid phases are mixed, they will fall into the reaction vessel 1. The nozzle 4 can be opened when necessary to discharge the already mixed liquid phase stored in the reaction vessel 1.

[0030] Among them, the mixing mechanism 2 includes a distribution pipe 21, through holes 22 and a cover plate 23. The distribution pipe 21 is either fixedly or detachably connected to the inner wall of the reaction vessel 1. The distribution pipe 21 communicates with the connecting pipe 3. A number of through holes 22 are formed on the distribution pipe 21, and a cover plate 23 is slidably arranged in each through hole 22.

[0031] Specifically, the cover plate 23 includes a mushroom top 231, a connecting rod 232 and a sliding plate 233. The top side of the mushroom top 231 is bent downward to form a concave surface with an opening downward. The mushroom top 231 is fixedly connected to the connecting rod 232, the connecting rod 232 is fixedly connected to the sliding plate 233, and the sliding plate 233 is elastically slidably connected to the inner wall of the through hole 22. A number of holes are formed on the sliding plate 233. During application, the liquid phase ejected from the through hole 22 will first hit the sliding plate 233. The dispersed liquid phase is recombined and ejected from the holes of the sliding plate 233 and injected into the concave surface of the mushroom top 231 to undergo a second dispersion, improving the mixing efficiency of the product for different liquid phases.

[0032] Example 3

[0033] Such as Figure 5 and Figure 6, A liquid-phase feed distributor, comprising a reaction vessel 1, a mixing mechanism 2, a connecting pipe 3 and a nozzle 4. A mixing mechanism 2 is installed inside the reaction vessel 1. A connecting pipe 3 and a nozzle 4 are detachably connected to the side surface of the reaction vessel 1 through bolt fasteners respectively. The connecting pipe 3 is at least a tee structure, one end of which is communicated with the mixing mechanism 2, and the other two ends are communicated with a pump. The liquid phase enters the mixing mechanism 2 through the ports of the corresponding connecting pipe 3 under the action of the corresponding pump, and is mixed by the mixing mechanism 2. Different liquid phases will fall into the reaction vessel 1 after mixing. The nozzle 4 can be opened when necessary to discharge the liquid phase that has been mixed and stored in the reaction vessel 1.

[0034] Among them, the mixing mechanism 2 includes a distribution pipe 21, through holes 22, a cover plate 23, a wire rope 24 and a limiting plate 25. The distribution pipe 21 is fixedly or detachably connected to the inner wall of the reaction vessel 1. The through holes 22 are opened on the upper surface of the distribution pipe 21. A plurality of cover plates 23 are hinged to the inner wall of the reaction vessel 1. Through the connection mode of the hinge, the cover plate 23 can be rotated to adjust the splashing path of the liquid-phase mixture ejected from the mixing mechanism 2 after hitting the cover plate 23, so that the mixed liquid phase can fall into the reaction vessel 1 from the inner ring side of the distribution pipe 21 as much as possible, converging the falling path of the liquid phase. During the falling process of a plurality of liquid phases, the mixing contact rate between the liquid phases can be improved again.

[0035] Preferably, the cover plate 23 can be rotatably connected to the reaction vessel 1 through a hinge with damping. Without manual adjustment, the damping can fix the position of the cover plate 23.

[0036] Preferably, the wire rope 24 penetrates through the side wall of the reaction vessel 1. One end of the wire rope 24 is fixedly connected to the corresponding cover plate 23, and the other end is fixedly connected to a hanging weight. The hanging weight is placed outside the reaction vessel 1 with damping sliding. By using the traction of the hanging weight and the self-weight of the cover plate 23, the position of the cover plate 23 can be limited. When there is no manual adjustment, the damping can fix the position of the hanging weight on the outside of the reaction vessel 1.

[0037] Preferably, the shape of the cover plate 23 is determined according to the shape of the distribution pipe 21. When the distribution pipe 21 is circular, the shape of the cover plate 23 is fan-shaped. When the distribution pipe 21 is rectangular, the cover plate 23 is straight plate-shaped.

[0038] Preferably, on the inner wall of the reaction vessel 1, above the gap between two cover plates 23, a limiting plate 25 is provided, and the limiting plate 25 is used to limit the upward turning angle of the cover plate 23.

[0039] The working principle of the present utility model:

[0040] In this application, by designing the distribution pipe 21, the through holes 22 and the cover plate 23, and using the blocking effect of the cover plate 23, the liquid phase ejected from the through holes 22 is dispersed after hitting the cover plate 23, which can preferably solve the problem that the sub-liquid phase feeding in the fine chemical reaction vessel needs to be fully dispersed. By placing the distributor in this application above or below the liquid level, different liquid phases, such as reaction raw materials and catalyst solutions, can be brought into full contact for reaction, improving the conversion rate of the reaction. Thus, the whole device can better reduce production energy consumption and material consumption.
