[0028] Please refer to Figure 1 - Figure 5 The utility model provides a technical scheme:

[0029] A microchannel reactor, comprising a mixing cavity 1.

[0030] In an embodiment of the utility model, mixed cavity 1 is provided with mixing assembly 2, mixing assembly 2 is provided with connecting cavity 21, connecting cavity 21 one end is fixedly installed on mixed cavity 1, connecting cavity 21 other end is fixedly installed with round pipe 22, connecting cavity 21 inboard is fixedly installed with triangular rod 23, mixed cavity 1 inboard is fixedly installed with square filter plate 24, mixed cavity 1 inboard rotatably installs long rod 25 one end, long rod 25 is fixedly installed with stirring wheel 26, long rod 25 other end is fixedly installed with power gear 27, mixed cavity 1 is fixedly installed with protective box 28, protective box 28 is fixedly installed with cover plate 29, cover plate 29 is fixedly installed with motor 210, connecting cavity 21, round pipe 22, triangular rod 23, square filter plate 24, long rod 25, stirring wheel 26 and power gear 27 are provided with multiple groups, multiple groups long rod 25, stirring wheel 26 are arranged between multiple groups square filter plate 24, multiple groups triangular rod 23 form triangular matrix, multiple groups power gear 27 are meshed with each other, multiple groups power gear 27 are arranged in protective box 28 inboard, wherein a group power gear 27 center point is connected with motor 210 output end.

[0031] When the reaction substance needs to enter the micro-channel reactor, the connecting cavity 21 on the mixing cavity 1 is connected with the round pipe 22, which provides a passage for the reaction substance to enter. The reaction substance flows into the connecting cavity 21 through the round pipe 22. At this time, the multiple groups of triangular rods 23 fixedly installed on the inboard of the connecting cavity 21 play a role. The multiple groups of triangular rods 23 form a triangular matrix, which preliminarily blocks and disperses the entering reaction substance, making the distribution of the reaction substance more uniform and laying a foundation for subsequent mixing and reaction. The reaction substance preliminarily dispersed by the triangular rods 23 enters the mixing cavity 1, and the square filter plate 24 further filters and disperses the reaction substance, filtering out some larger particle impurities in the reaction substance, while further dispersing the reaction substance as it passes through the square filter plate 24, increasing the contact area between the reaction substances and improving the possibility of reaction. At the same time, the motor 210 is started, and the output end of the motor 210 drives a group of power gears 27 to rotate. Since the multiple groups of power gears 27 are meshed with each other and arranged on the inboard of the protective box 28, the rotation of this group of power gears 27 will drive the other power gears 27 to rotate synchronously. The rotation of the power gears 27 drives multiple groups of long rods 25 and stirring wheels 26 to rotate. The stirring wheels 26 stir and mix the reaction substance between the square filter plates 24. Through the synergistic effect of the triangular rods 23, square filter plates 24, and stirring wheels 26, the reaction substance can be fully contacted and mixed in the mixing cavity 1, improving the uniformity and efficiency of the reaction and providing good conditions for the chemical reaction in the micro-channel reactor, ensuring the quality and stability of the reaction.

[0032] In one embodiment of this utility model, an auxiliary component 3 is provided on the circular tube 22. The auxiliary component 3 includes a circular filter plate 31. The circular filter plate 31 is fixedly installed on the inner side of the circular tube 22. A circular rod 32 is rotatably installed on the circular filter plate 31. A power turbine 33 is fixedly installed on one end of the circular rod 32, and a stirring turbine 34 is fixedly installed on the other end of the circular rod 32.

The power turbine 33 is located inside the circular tube 22, and the stirring turbine 34 is located inside the connecting cavity 21.

[0033] In this embodiment, during the process of the reactants entering the connecting cavity 21 through the circular tube 22, the auxiliary component 3 begins to function. A circular filter plate 31 is fixedly installed inside the circular tube 22. The circular filter plate 31 filters the reactants entering the circular tube 22, removing impurities and ensuring the purity of the reactants entering the reactor. This prevents impurities from adversely affecting the reaction. When the reactants flow inside the circular tube 22, they drive the power turbine 33 to rotate. The rotation of the power turbine 33 drives the circular rod 32 to rotate, which in turn causes the stirring turbine 34 inside the connecting cavity 21 to rotate. The stirring turbine 34 stirs the reactants again inside the connecting cavity 21, further promoting the mixing of the reactants. This allows reactants of different components to come into more complete contact and react. The coordinated work of multiple power turbines 33 and stirring turbines 34 not only optimizes the mixing effect of the reactants in the circular tube 22 and connecting cavity 21, but also promotes the flow of reactants to a certain extent, improving the transport efficiency of the reactants and ensuring that the reactor can operate stably and efficiently.
