Abstract
Description
Technical Field
[0001] The present application relates to the technical field of liquid mixing, and in particular to a liquid mixing device for exothermic reactions. Background Art
[0002] Liquid mixing is required in many process flows, and such liquid mixing is exothermic, such as acid-base mixing. At the same time, when some liquids are added and mixed synchronously with other materials, overheating will cause other materials to overreact. For example, in the preparation of hydrophilic resins, overheating of the polymerization monomer reaction liquid during neutralization will lead to the production of oligomers, which will ultimately affect the quality of the prepared hydrophilic resin. Therefore, temperature control is usually required in the liquid mixing step of the exothermic reaction.
[0003] Conventional temperature control involves wrapping a jacketed coil cooling device around the outside of the mixing tank, controlling the temperature through external heat exchange. However, this method is ineffective, leading to excessively intense mixing reactions within the tank. To ensure production safety, a set cooling time is required, preventing continuous mixing and resulting in low production efficiency. This can also affect the quality of the final product.

[0037] See Figure 1 , Figure 1 This is a schematic structural diagram of an embodiment of the present application.
[0038] The present invention provides a liquid mixing device for an exothermic reaction, comprising a mixing tank 110 and a first liquid tank 120. The first liquid tank 120 is connected to an infusion assembly, which delivers a first liquid into the mixing tank 110. The mixing tank 110 is used to store a second liquid and to mix the first and second liquids.
[0039] The mixing tank 110 is connected to a heat exchanger 130, which is communicated with the mixing tank 110 and is used to circulate heat for the liquid in the mixing tank 110. That is, the heat exchanger 130 directly cools the liquid in the mixing tank 110, which can quickly reduce the temperature in the tank and improve the temperature control effect, thereby achieving efficient and safe production.
[0040] It is understandable that the second liquid in the mixing tank 110 can be put into place at one time before mixing, or it can be continuously input through a pipeline, and the first liquid tank 120 can also continuously input it to achieve continuous mixing in the mixing tank 110 and output it through another pipeline.
[0041] In one embodiment, the circulation outlet of the heat exchanger 130 is located inside the mixing tank 110 and is arranged close to the top of the mixing tank 110. A diffuser plate 140 is provided corresponding to the circulation outlet. The diffuser plate 140 is used to disperse the liquid cooled by the heat exchanger 130 to form a fluid similar to a waterfall, thereby achieving large-area dispersion of the liquid.
[0042] Furthermore, the infusion outlet of the infusion component is located inside the mixing tank 110, and is close to and above the diffuser plate 140, so that most of the liquid output from the infusion outlet is first mixed with the waterfall flow liquid with a larger area and lower temperature, so that a small amount of liquid can be pre-mixed in a larger space, which can further control the mixing temperature rise, thereby further improving the mixing safety and improving production efficiency.
[0043] See Figure 2-3 , Figure 2 for Figure 1 A schematic diagram of the enlarged structure of part A from another angle; Figure 3 for Figure 2 Schematic diagram of the top view structure.
[0044] In one embodiment, the infusion outlet of the infusion assembly is provided with a liquid limiting member 150, which is in the shape of an inverted funnel and is located within the range of the vertical projection of the diffuser plate 140. The liquid limiting member 150 controls the falling direction of the liquid output from the infusion outlet and guides the diffusion of the liquid, so that the liquid output from the infusion outlet is dispersed and contacts the liquid on the diffuser plate 140 over a larger area, further controlling the mixing temperature rise, improving the mixing safety, and further improving the production efficiency.
[0045] In a specific embodiment, the infusion assembly includes an infusion tube 160, one end of which is connected to the first liquid tank 120, and the other end extends into the mixing tank 110. The end of the infusion tube 160 is the infusion outlet of the infusion assembly, and a limited liquid part 150 is provided.
[0046] In one embodiment, the diffuser plate 140 is arranged at an angle, and the highest point is located directly below the circulation outlet, thereby improving the diffuser effect of the diffuser plate 140 .
[0047] In one embodiment, the diffuser plate 140 is a fan-shaped plate, and the center of the diffuser plate 140 is the highest point of the diffuser plate 140. The two side edges of the fan-shaped plate are tilted outward to guide the mixed liquid to further diffuse, thereby achieving dispersion and larger area contact with the liquid surface inside the mixing tank 110, further controlling the mixing temperature rise, improving the mixing safety, and further improving the production efficiency.
[0048] Please see again Figure 1 In one embodiment, the heat exchanger 130 is connected to a circulation output pipe 131, which extends into the mixing tank 110, and the end of the circulation output pipe 131 is the circulation outlet of the heat exchanger 130. A diffuser plate 140 is provided at the end of the circulation output pipe 131, that is, the heat sink is installed on the circulation output pipe 131 to fix the heat sink, and is easy to disassemble from the mixing tank 110 together with the circulation output pipe 131, thereby improving maintenance convenience.
[0049] In one embodiment, the heat exchanger 130 is connected to a circulation input pipe 132 , which is connected to the bottom of the mixing tank 110 . The circulation input pipe 132 is connected to a reflux pump 133 to achieve cyclic heat exchange.
[0050] In one embodiment, the liquid infusion tube 160 is connected to a regulating valve 161 to control the mixing reaction.
[0051] In one embodiment, a stirring mechanism 111 is provided in the mixing tank 110 to improve mixing efficiency and mixing effect.
[0052] In one embodiment, the outer side of the mixing tank 110 is covered with a jacketed coil cooling device 112 to cool the mixing tank 110 and improve mixing safety.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
