Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and more specifically, to a continuous aging device for a microfluidic reactor. Background Technology

[0002] Continuous flow microreactors are a novel type of reaction device based on microfluidic technology. They enable continuous flow of reactants and chemical reactions through micron-level channels. Their core advantages include efficient mass and heat transfer, precise control of the reaction process, high safety, and compliance with green production trends. They are widely used in fine chemicals (such as the synthesis of pharmaceutical intermediates), nanomaterial preparation (such as the synthesis of nanoparticles with uniform particle size), energy and environmental protection (such as the efficient synthesis of fuel cell catalysts).

[0003] However, in current reaction equipment, the flow rate of raw materials is fixed after entering the reactor, resulting in insufficient residence time, inadequate heating of the mixed liquid, and uneven mixing effect. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a continuous aging device for a microfluidic reactor to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A continuous aging device for a microfluidic reactor includes three raw material tanks, a reaction vessel, and an aging vessel. A spiral pipe is installed inside the reaction vessel, with both ends of the spiral pipe penetrating and fixed to the outside of the reaction vessel. One end of the spiral pipe is equipped with a conveying mechanism for inputting the raw materials from the three raw material tanks, and the other end of the spiral pipe is equipped with an output pump connected to the aging vessel.

[0013] As a further description of the above technical solution: the aging tank is equipped with an aging operation sensor light and a timer, which are used to start the aging timer after the feeding is completed and to turn on the aging operation sensor light after the aging time is completed.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This scheme utilizes a spiral pipe in conjunction with a spherical inner cavity to reduce the flow rate of the mixed liquid entering the reactor, thereby achieving the advantages of improved mixing uniformity and heating uniformity of the device.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] To address the problem in current reaction equipment where the raw materials enter the reactor at a fixed flow rate, resulting in insufficient residence time and inadequate heating of the mixed liquid, Example 1 is proposed:

[0025] Please see Figure 1 and Figure 3 In this embodiment, a continuous aging device for a microfluidic reactor includes three raw material tanks 1, a reaction vessel 2, and an aging vessel 3. A spiral pipe 4 is installed inside the reaction vessel 2, and both ends of the spiral pipe 4 are connected to the outside of the reaction vessel 2. One end of the spiral pipe 4 is provided with a conveying mechanism 5 for inputting the raw materials inside the three raw material tanks 1. The other end of the spiral pipe 4 is provided with an output pump 6 connected to the aging vessel 3. A hot oil circulation mechanism 7 is installed on the reaction vessel 2.

[0026] The spiral pipe 4 is provided with spherical inner cavities 41 arranged in a spiral at equal intervals, and the inner diameter of the spherical inner cavity 41 is larger than the inner diameter of the spiral pipe 4.

[0027] The material conveying mechanism 5 includes a four-way pipe 51 and three input pumps 52. Three ends of the four-way pipe 51 are respectively connected to three raw material tanks 1 through the input pumps 52.

[0028] The hot oil circulation mechanism 7 includes a hot oil furnace 71, a circulation pump 72, and a return pipe 73. The hot oil furnace 71 is used to heat the heat transfer oil and input it into the interior of the reactor 2 through the circulation pump 72. The return pipe 73 is used for the hot oil inside the reactor 2 to flow back into the hot oil furnace 71 for circulation.

[0029] The aging tank 3 is equipped with a mixer 31; the aging tank 3 is equipped with a feed sensor light 32 to indicate when the output pump 6 is feeding and to turn off when feeding stops.

[0030] The aging tank 3 is equipped with an aging operation sensor light 33 and a timer 34, which are used to start the aging timer 34 after the feeding is completed and to turn on the aging operation sensor light 33 after the aging time is completed.

[0031] In this embodiment, the input pump 52 draws and mixes the raw material liquid from the three raw material tanks 1 through the four-way pipe 51 and injects it into the spiral pipe 4. At the same time, the hot oil from the circulating pump 72 and the hot oil furnace 71 is injected into the reaction vessel 2 to heat the mixture inside the spiral pipe 4, causing it to react. During the heating process inside the spiral pipe 4, the spherical inner cavity 41 causes the mixture to flow through the spiral pipe 4. Due to the change in the diameter of the pipe, when the liquid flows from the smaller diameter into the larger diameter spherical inner cavity 41, collisions and agitations occur, improving the mixing uniformity. To ensure uniformity, the flow rate is reduced while the heating time is increased, allowing the mixture to react more fully. After the mixture reacts, it is injected into each aging tank 3 via an independent output pump 6 for aging. When the output pump 6 starts, the feed sensor 32 lights up. After feeding is completed, the feed sensor 32 goes out, and the timer 34 receives the signal that the feed sensor 32 has gone out and starts timing to begin the aging process. At the same time, the agitator 31 is started to stir the reaction liquid inside the aging tank 3, increasing the aging speed. This achieves the advantages of the device: after the raw materials enter the heating space, the flow rate is reduced, improving the mixing and heating efficiency.

[0032] Furthermore, to address the issue of insufficient uniformity in liquid mixing, a second embodiment is proposed:

[0033] Please see Figure 2 and Figure 4 The spiral pipe 4 and the four-way pipe 51 are connected by a guide rod 8 inside the section that is rotatably installed. The end of the guide rod 8 away from the reactor 2 is fixedly installed with a blade 9. The outside of the guide rod 8 is fixedly connected with a stirring rod 10.

[0034] In this embodiment, the internal mixture flows and drives the blade 9 to rotate, thereby driving the guide rod 8 and the stirring rod 10 to mix and stir the incoming liquid, improving the mixing effect of the mixture entering the reactor 2, thus achieving the advantage that the device has a more thorough mixing effect on the reaction liquid.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
