Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 — Figure 4 ,in, Figure 1 Schematic diagram of the overall structure of the microflow reaction device provided by this utility model Figure 1 ; Figure 2 Schematic diagram of the overall structure of the microflow reaction device provided by this utility model Figure 2 ; Figure 3 A cross-sectional view of the microflow reaction device provided by this utility model; Figure 4 A cross-sectional view of the mixing cylinder provided by this utility model.

[0023] In specific implementation, a microflow reaction device has the following structure: Figure 1 — Figure 4 As shown, it includes: a reaction chamber 1 and a pumping unit 2. The pumping unit 2 is located on one side of the reaction chamber 1. An input pipe 3 is inserted through the side wall of the reaction chamber 1. A first slow-flow pipe 4 is bolted inside the reaction chamber 1. One end of the first slow-flow pipe 4 is bolted to the input pipe 3. The other end of the first slow-flow pipe 4 is bolted to a mixing cylinder 5. A second slow-flow pipe 6 is inserted through one side of the mixing cylinder 5. An output pipe 7 is inserted through one end of the second slow-flow pipe 6. The output pipe 7 passes through the side wall of the reaction chamber 1. Multiple conduits 8 are inserted inside the input pipe 3. The other ends of the multiple conduits 8 are all inserted into the pumping unit 2. A detection component 9 is bolted to one end of the output pipe 7. A drain outlet 10 is inserted through one side of the detection component 9. A waste liquid tank 11 is bolted to one side of the detection component 9.

[0024] It should be noted that the pumping member 2 is a peristaltic pump, and a plurality of conduits 8 are provided with one-way valves (not shown in the figure). When the solution is detected and mixed, the two groups of solutions are transported through the plurality of conduits 8 by the peristaltic pump. The solutions are preliminarily mixed at the input pipe 3. Since the conduits 8 are provided with one-way valves, the solution backflow can be avoided. The solution entering the input pipe 3 is transported into the mixing cylinder 5 through the first slow-flow pipe 4. The mixing cylinder 5 is provided with the fixed column 12. The fixed column 12 is fixedly connected with a plurality of drainage assemblies 13 on the side wall. The other end of the plurality of drainage assemblies 13 is fixedly connected to the inner side wall of the mixing cylinder 5. The plurality of drainage assemblies 13 are linearly arranged along the side wall of the fixed column 12. The solution is divided and then converged through the plurality of drainage assemblies 13, so that the solution is further mixed through multiple collisions, thereby making the solution reaction more sufficient. The fully mixed solution is transported into the detection assembly 9 through the second slow-flow pipe 6. The detection assembly 9 selects a detection instrument matched with the reaction. The solution after being detected by the detection instrument is discharged into the waste liquid tank 11 through the drain 10, thereby avoiding environmental pollution.

[0025] The bottom end of the first slow-flow pipe 4 is bifurcated, so that the solution forms a flow when entering the mixing cylinder 5, thereby making the solution collide with the top layer of the drainage assembly 13 to mix the solution for the first time.

[0026] The drainage assembly 13 includes the first drainage block 14 and the second drainage block 15. The first drainage block 14 is in the shape of a circular truncated cone and is fixedly connected to the side wall of the fixed column 12. The second drainage block 15 is in the shape of a circular column with a circular truncated cone-shaped through hole. The second drainage block 15 is fixedly connected to the inner side wall of the mixing cylinder 5.

[0027] It should be noted that when the solution enters the mixing cylinder 5, the solution is first divided by the first drainage block 14. The solution flows down along the side wall of the first drainage block 14 and flows to the second drainage block 15. The solution flows to the first drainage block 14 of the next layer through the second drainage block 15, so that the solution is mixed again by impact. The solution is mixed by impact for multiple times through the cooperation of the first drainage block 14 and the second drainage block 15, so that the solution is fully mixed, thereby reducing the setting of the spiral pipe and fully mixing the solution to make the reaction heat be fully released.

[0028] The reaction tank 1 is provided with an inlet 16 and an outlet 17 on the side wall. The outlet 17 is located above the inlet 16. The inlet 16 and the outlet 17 are provided with water stop valves (not shown in the figure).

[0029] It should be noted that the cooling liquid is injected into the reaction box 1 through the injection port 16 and is discharged through the flow port 17, and since the injection port 16 is located below the flow port 17, the cooling liquid can sufficiently cool the first slow-flow pipe 4, the second slow-flow pipe 6 and the mixing cylinder 5, thereby avoiding waste of the cooling liquid.

[0030] The first slow-flow pipe 4 and the second slow-flow pipe 6 are both spiral-shaped, so that the time of the elongated solution in the reaction box 1 is prolonged, the reaction is sufficient, and the spiral-shaped first slow-flow pipe 4 and the second slow-flow pipe 6 can increase the contact area with the cooling liquid, so that the cooling is more sufficient.

[0031] The circuit and the control involved in the utility model are prior art, and will not be described in detail here.

[0032] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
