Description

Technical Field

[0001] This utility model relates to a reaction vessel, specifically, to a non-phenolic thermosensitive colorimetric reagent reaction vessel, belonging to the field of colorimetric reagent production technology. Background Technology

[0002] Traditional phenolic color developers (especially bisphenol A and BPA) pose potential health and environmental risks, making non-phenolic alternatives a current research hotspot. Non-phenolic thermosensitive color developers are a class of chemical substances that do not contain phenolic compounds and are used in thermosensitive materials to trigger a color reaction through heating.

[0003] The dropper of a traditional non-phenolic thermosensitive colorimetric reagent reactor is usually fixed. When highly reactive reactants are added, the added liquid will be concentrated in a small area and cannot be quickly dispersed into the entire reaction system. This will lead to an excessively high local concentration, which can easily trigger side reactions and generate impurities.

[0004] Traditional non-phenolic thermosensitive colorimetric reagent reactors rely solely on mechanical stirring, which has limited effect on the dispersion of reactants and the deagglomeration of solid particles. Insufficient mixing leads to incomplete contact of reactants and unstable quality.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a non-phenolic thermosensitive colorimetric reagent reaction vessel, which can solve the problems of uneven material mixing and excessively high local concentration caused by traditional dropwise addition methods, as well as the problem of incomplete contact of reactants due to insufficient mixing.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A non-phenolic thermosensitive colorimetric reagent reaction vessel includes a reaction vessel body installed inside a temperature-controlled vessel body. Multiple first supports are fixedly installed around the reaction vessel body, with the first supports located at the top of the temperature-controlled vessel body. Multiple circumferentially distributed ultrasonic transducers are fixedly installed at the bottom of the reaction vessel body, located within a cavity between the temperature-controlled vessel body and the reaction vessel body. A rotating shaft is installed inside the reaction vessel body, with a conical dropping funnel fitted onto the upper part of the shaft's main body. At least two dropping tubes are fixedly connected to the outer periphery of the bottom of the dropping funnel's inner cavity.

[0008] Furthermore, the bottom of the dripping bucket is fixed to the rotating shaft and rotates synchronously with the rotating shaft, and the top of the dripping bucket is provided with a constriction opening.

[0009] Furthermore, the dripping tube is connected to the inner cavity of the dripping chamber, the dripping tube is set horizontally, and the bottom wall of the dripping tube is provided with a dripping hole.

[0010] Furthermore, a flow guide pipe is fixedly installed on the top of the reactor body, and the output port of the flow guide pipe is located inside the nozzle.

[0011] Furthermore, the top of the temperature-controlled vessel is provided with a circular mounting hole, through which the reaction vessel is installed into the temperature-controlled vessel.

[0012] Furthermore, multiple second supports are fixed around the temperature-controlled vessel body, and the second supports are connected to the support legs.

[0013] Furthermore, the bottom of the temperature-controlled vessel is provided with a temperature-controlled medium inlet, and the top side of the temperature-controlled vessel is provided with a temperature-controlled medium outlet.

[0014] Furthermore, the reactor body is provided with a feed inlet at the top and a discharge pipe at the bottom, with the discharge pipe extending out from the bottom wall of the temperature-controlled reactor body.

[0015] Furthermore, a stirring blade is installed on the bottom of the rotating shaft.

[0016] Furthermore, the top of the rotating shaft is connected to the output shaft of the geared motor via a coupling.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By rotating the dropper, the added liquid is evenly sprayed onto all parts of the reactor under centrifugal force, realizing the transformation from point to surface and fundamentally avoiding the problem of excessively high local concentration. Based on mechanical stirring, an ultrasonic transducer was introduced. The high-frequency vibration energy generated by the ultrasonic wave can produce extremely strong shear force, realizing efficient mixing and homogenization of materials, ensuring full contact of reactants, and improving reaction efficiency and product consistency. The temperature-controlled vessel provides a stable and uniform temperature environment. Combined with the efficient mixing brought by mechanical stirring, ultrasonic waves, and rotary dripping, it can quickly transfer the heat of reaction to the temperature-controlled wall, ensuring that the entire reaction system is within a constant, preset optimal temperature range.

Detailed Implementation

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown in the figure, this utility model provides a non-phenolic thermosensitive colorimetric reagent reaction vessel, including a reaction vessel body 1, which is installed inside a temperature-controlled vessel body 2. The temperature-controlled vessel body 2 has a circular mounting hole at its top, through which the reaction vessel body 1 is installed inside the temperature-controlled vessel body 2. A plurality of first supports 3 are fixedly installed around the reaction vessel body 1, and the first supports 3 are located at the top of the temperature-controlled vessel body 2.

[0023] Multiple second supports 4 are fixed around the temperature-controlled vessel body 2, and the second supports 4 are connected to the support legs.

[0024] Multiple circumferentially distributed ultrasonic transducers 7 are fixedly installed at the bottom of the reactor body 1, and the ultrasonic transducers 7 are located in the cavity between the temperature-controlled vessel body 2 and the reactor body 1. The ultrasonic transducers 7 can convert high-frequency electrical signals into mechanical vibrations, enabling efficient dispersion and mixing of different components in the reactor body 1, and achieving uniform distribution of materials.

[0025] The temperature-controlled vessel body 2 has a temperature-controlled medium inlet 5 at the bottom and a temperature-controlled medium outlet 6 on one side of the top.

[0026] The reactor body 1 is provided with a feed inlet 8 at the top and a discharge pipe 9 at the bottom, which extends out from the bottom wall of the temperature-controlled reactor body 2.

[0027] The reactor body 1 is equipped with a rotating shaft 10 inside. A stirring blade is installed on the bottom of the rotating shaft 10. The top of the rotating shaft 10 is connected to the output shaft of the geared motor through a coupling. The blade rotates at high speed with the geared motor to mix the materials and achieve uniform distribution.

[0028] The upper part of the main body of the rotating shaft 10 is fitted with a dropping funnel 11, which has a conical structure. The bottom of the dropping funnel 11 is fixed to the rotating shaft 10 and rotates synchronously with the rotating shaft 10. The top of the dropping funnel 11 is provided with a constriction opening 12, through which the dropping liquid enters the dropping funnel 11. The advantage of the conical design is to prevent the dropping liquid inside from being thrown out under centrifugal force.

[0029] At least two drip tubes 13 are fixedly connected to the outer periphery of the bottom of the dripping bucket 11. The drip tubes 13 are connected to the inner cavity of the dripping bucket 11. The drip tubes 13 are arranged in a horizontal direction, and a dripping hole is provided on the bottom wall of the drip tube 13.

[0030] A flow guide pipe 14 is fixedly installed on the top of the reactor body 1, and the output port of the flow guide pipe 14 is located inside the inlet 12.

[0031] Taking the synthesis of a sulfonamide-based non-phenolic colorimetric reagent as an example, the specific working principle of this invention can be explained as follows: High-purity solvent is added to the reactor, and the temperature control system is activated to raise the solvent to the preset reaction temperature. Amine compounds are slowly and precisely added to the reactor, and a geared motor is turned on for mechanical stirring, while an ultrasonic transducer is activated to deeply homogenize the materials. Then, under strict temperature and pH control, sulfonyl chloride is precisely and uniformly added dropwise to the reaction system in a highly dispersed state. After the addition is complete, the reaction is maintained at a constant temperature under continuous mechanical stirring and ultrasonic assistance to ensure complete reaction. After the reaction is finished, the synthesized non-phenolic thermosensitive colorimetric reagent product is discharged through the discharge pipe at the bottom.
