Embodiment 1

[0032] Such as Figure 1-Figure 7 Shown, a kind of reaction device that is used for Suzuki coupling reaction comprises support frame 1, the reaction kettle body 2 that is installed on the support frame 1 and the liner 3 that is located in the reaction kettle body 2, described liner 3 and The reactor body 2 is provided with a hollow cavity 4, the bottom of the reactor body 2 is provided with a liquid inlet 5 communicating with the hollow cavity 4, and the side of the reactor body 2 top is provided with a liquid inlet 5 connected with the hollow cavity 4. Through the liquid outlet 6, in the interlayer between the reactor body 2 and the inner tank 3, heating or freezing is adopted to make the material react more fully and complete the entire production process. The bottom of the inner tank 3 At least two outlets 7 are provided, wherein one end of the outlet 7 near the inner tank 3 is provided with a filter screen 8, the reaction process and the separation process are coupled in o...

Embodiment 2

[0039] Embodiment 2: as Figure 1-Figure 7 shown

[0040] At present, the inner liner of the double-layer glass reactor produced by many domestic production enterprises is smooth, which results in low mixing uniformity of the material. The original glass inner liner is smooth, and it is easy to produce synchronous rotation of the material and the stirring paddle during mechanical stirring. The efficiency is low, because the inner tank is smooth, the materials are not subject to resistance, and the materials react slowly with each other. Therefore, there is an urgent need for an improved technology to solve the problems in the prior art.

[0041] The spoiler baffle assembly 9 includes a first set of spoiler baffles 901 and a second set of spoiler baffles 902 , and the first set of spoiler baffles 901 and the second set of spoiler baffles 902 are arranged alternately up and down.

Embodiment 3

[0042] Embodiment 3: as Figure 1-Figure 7 shown

[0043]The agitator is usually inserted vertically into the kettle from the center of the top of the kettle, the strength of the top of the kettle is low, and the stirring stability is very poor.

[0044] A supporting seat assembly 14 is arranged on the inner wall of the inner container 3, and the top end of the supporting seat assembly 14 is in conflict with one end of the stirring shaft 13. By setting the supporting seat assembly 14 at the bottom of the inner container 3, the stability of the stirring device is improved.

[0045] In this embodiment, the support seat assembly 14 includes support feet 141 integrally formed on the inner container 3, the support feet 141 are distributed along the side of the outlet 7 of the center line of the inner container 3, and the support feet 141 A supporting block 142 is arranged on the top of the foot 141 , and the stirring shaft 13 is arranged on the supporting block 142 , and the stirr...

Thedevice comprises a support frame, a reaction kettle body mounted on the support frame and an inner container arranged in the reaction kettle body, a hollow cavity is formed between the inner container and the reaction kettle body, a liquid inlet communicated with the hollow cavity is formed in the bottom end of the reaction kettle body, a liquid outlet communicated with the hollow cavity is formed in the side face of the top end of the reaction kettle body, at least two discharging openings are formed in the bottom end of the inner container, and a filter sieve is arranged at the end, close to the inner container, of one discharging opening; a turbulent flow baffle assembly is arranged on the inner wall of the inner container and comprises a plurality of turbulent flow baffles, and the plurality of turbulent flow baffles are arranged along the inner wall of the inner container at equal intervals. According to the invention, the function of separating liquid from solid in the product is realized, and the multifunctional purpose of single equipment is realized; the chemical reaction is more sufficient, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical reaction equipment, and in particular relates to a device for coupling reaction. Background technique [0002] The double-layer glass reaction kettle includes a reaction tank, an electric mixer, a condenser and a liquid storage tank. The inner container of the double-layer glass reaction kettle can introduce freezing liquid, water and high-temperature liquid through the interlayer to heat up and cool the material. At the same time, a vacuum pump is added to carry out Vacuuming, so as to realize the high temperature and reduced pressure concentration of the product, and the pilot test of low temperature crystallization. Double-layer glass reactor is the ideal equipment for Suzuki coupling reaction. However, there are some drawbacks in the prior art reactors. When there are solid and liquid materials in the Suzuki coupling reaction system, a stirring device is often needed to mix the solid and li...
