[0023] This utility model discloses a novel stepped mixer. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0024] Combination Figure 1 and Figure 2 As shown, a novel stepped mixer includes a first heat exchange plate 1, a partition plate 2, a mixing plate 3, and a second heat exchange plate 4. The first heat exchange plate 1, partition plate 2, mixing plate 3, and second heat exchange plate 4 are sequentially and tightly fitted together, and adjacent components are detachably fixed together by bolts. A mixing channel 5 is provided on the bottom surface of the mixing plate 3, and a sealing groove 14 is formed on the outer periphery of the mixing channel 5. An O-ring is disposed within the sealing groove 14, and the mixing plate 3 and partition plate 2 are sealed together by the O-ring. The mixing channel 5 is divided into a first mixing unit 15, a second mixing unit 16, and a third mixing unit 17, which are sequentially connected and each has a mixing section 18 inside. The mixing section 18 is formed by an S-shaped first partition plate 2. The top of the mixing section 18 is lower than the top surface of the mixing plate 3, and a support member 26 protrudes upward at the corner of each first partition plate 2. The bottom surface of the support member 26 is at the same height as the top surface of the mixing plate 3. In this embodiment, the thickness of the partition 2 is no more than 1 mm, which is used to ensure the effective transfer of heat between the reaction fluid and the heat exchange fluid.

[0025] Combination Figure 3 and Figure 4As shown, a first feed inlet is provided on the left side wall of the mixing plate 3, and a second feed inlet 9 is provided on the right side wall. The first feed inlet is connected to the bottom left side of the first mixing unit 15, and the second feed inlet 9 is connected to the bottom right side of the first mixing unit 15. The first mixing unit 15, the second mixing unit 16, and the third mixing unit 17 all have a mixing section 18. A first distribution plate 20 is provided between the first mixing unit 15 and the second mixing unit 16, a second distribution plate 22 is provided between the second mixing unit 16 and the third mixing unit 17, and the third mixing unit 17 is connected to a third distribution plate 23. The first distribution plate 20, the second distribution plate 22, and the third distribution plate 23 all have several staggered turbulence columns 24.

[0026] A second partition 19 is provided between one side of the first dispensing plate 20 and the first mixing unit 15, and the other side is connected to both sides of the second mixing unit 16 through a curved connecting groove 21. A second partition 19 is also provided between one side of the second dispensing plate 22 and the second mixing unit 16, and the other side is connected to both sides of the third mixing unit 17 through a curved connecting groove 21. A third partition is provided between one side of the third dispensing plate 23 and the third mixing unit 17, and the other side is connected to the discharge port 10 opened on the rear side wall of the mixing plate 3.

[0027] Combination Figure 5 and Figure 6 As shown, a first heat exchange channel 8 is provided on the bottom surface of the first heat exchange plate 1, and a second heat exchange channel 13 is provided on the bottom surface of the mixing plate 3. Sealing grooves 14 are provided on the outer periphery of both the first and second heat exchange channels 8 and 13, and O-rings are disposed within the sealing grooves 14. The first heat exchange plate 1 and the partition plate 2 are sealed by O-rings, and the mixing plate 3 and the second heat exchange plate 4 are also sealed by O-rings. Both the first and second heat exchange channels 8 and 13 are hexagonal, and each contains several staggered flow-blocking blocks 25, each with an isosceles triangular cross-section. A first heat exchange inlet 6 is provided on the front sidewall of the first heat exchange plate 1, and the first heat exchange inlet 6 communicates with the front side of the bottom of the first heat exchange channel 8. A first heat exchange outlet 7 is provided on the rear sidewall of the first heat exchange plate 1, and the first heat exchange outlet 7 communicates with the rear side of the bottom of the first heat exchange channel 8. A second heat exchange inlet 11 is provided on the front side wall of the second heat exchange plate 4, and the second heat exchange inlet 11 is connected to the front side of the second heat exchange channel 13. A second heat exchange outlet 12 is provided on the rear side wall of the second heat exchange plate 4, and the second heat exchange outlet 12 is connected to the rear side of the second heat exchange channel 13. In the first heat exchange channel 8, the apex of each flow-blocking block 25 faces the first heat exchange inlet 6; in the second heat exchange channel 13, the apex of each flow-blocking block 25 faces the second heat exchange inlet 11. Each flow-blocking block 25 can effectively prevent the partition plate 2 from deforming while ensuring heat exchange efficiency through its dense and uniform arrangement.

[0028] In use, the first heat exchange plate 1, partition plate 2, mixing plate 3, and second heat exchange plate 4 are arranged and installed sequentially from top to bottom. The first heat exchange inlet 6, the first heat exchange outlet 7, the second heat exchange inlet 11, and the second heat exchange outlet 12 are respectively connected to external heat exchange pipes. The first feed inlet is connected to the first feed pipe, the second feed inlet 9 is connected to the second feed pipe, and the discharge outlet 10 is connected to the discharge pipe. Operators use the first and second feed pipes to introduce different liquid materials into the mixing channel 5. The two different liquid materials are separated into several thin streams by the S-shaped first partition, and the two different liquid materials interweave. As the liquid materials are continuously introduced, the two different liquid materials will undergo preliminary mixing at the top of the first partition, and the preliminarily mixed liquid enters the first distribution plate 20 through the second partition 19. The first dispensing plate 20 has several turbulent flow columns 24, which further mix the initially mixed liquid. The initially mixed liquid then enters the left and right sides of the second mixing unit 16 through the connecting groove 21. Both sides of the second mixing unit 16 are provided with several turbulent flow columns 24, which further mix the initially mixed liquid. The liquid entering the left and right sides of the second mixing unit 16 then undergoes a second mixing through the mixing section 18. The liquid after the second mixing passes through the second partition 19 into the second dispensing plate 22, where the several turbulent flow columns 24 further mix the liquid. The liquid after the second mixing then enters the left and right sides of the third mixing unit 17 through the connecting groove 21. The structure and material mixing process of the third mixing unit 17 are approximately the same as those of the second mixing unit 16. The liquid after the second mixing undergoes a third mixing in the mixing section 18 within the third mixing unit 17. After the third mixing, the liquid enters the third distribution plate 23 through the second partition 19. The turbulent flow column 24 located in the third distribution plate 23 further mixes the liquid after the third mixing. Then, the liquid after the third mixing flows out of the mixing plate 3 through the discharge port 10.

[0029] There is no specific limit to the number of mixing units; staff can flexibly increase the number of mixing units according to the difficulty of mixing the liquid materials.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
