[0002] The core part of the microchannel reactor is a network composed of micron-scale channels. These microchannels are made of materials such as glass, silicon, stainless steel or polymers. The reactor is usually equipped with a feeding device, a control device and a product collection device. The feeding device is responsible for introducing the reactants into the microchannel, the control system is used to adjust the reaction conditions such as temperature, pressure and flow rate, and the product collection system is used to collect the products after the reaction. The current microchannel reactor is suitable for fast and efficient chemical reactions, especially in synthetic reactions, catalytic reactions and biochemical reactions. It is used after being connected to the microchannel through a feeding pipe. However, most of the internal microchannel reactors do not have a supporting structure. The feeding pipe is difficult to fix when connected to the microchannel, and the feeding pipe needs to be manually supported, which may lead to unstable connection, thereby affecting the accuracy and repeatability of the reaction.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a microchannel reactor includes a base 1, a support plate 2 and a controller 3 are fixedly connected above the base 1, a microchannel body 13 is provided above the base 1, a delivery pipe 8 is fixedly connected to one side of the controller 3, an adjustment structure 6 is provided on the base 1, a positioning plate 5 is provided on the support plate 2, the positioning plate 5 is connected to the adjustment structure 6, the adjustment structure 6 is rotatably connected to the support plate 2, a feed pipe 4 is clamped in the support plate 2, a sealing ring 1 9 is provided on the outside of the feed pipe 4, a sealing ring 2 10 is provided on the outside of the delivery pipe 8, a positioning structure 7 is connected to the outside of the sealing ring 10, and the positioning structure 7 is overlapped with the sealing ring 1 9;

[0022] The adjustment structure 6 includes a concave plate 601, a gear 604 and a guide rod 607. A threaded rod 603 is rotatably connected inside the concave plate 601. A motor 602 is fixedly connected below the concave plate 601. The threaded rod 603 is externally threadedly connected to a movable plate 605. A toothed plate 606 is fixedly connected to the side of the movable plate 605.

[0023] like Figure 1 and Figure 3As shown, a slide groove 11 is opened outside the feed pipe 4, and a sealing ring 9 is slidably connected in the slide groove 11. A slide groove 2 is opened outside the delivery pipe 8, and a sealing ring 2 10 is slidably connected in the slide groove 2 12. The positioning plate 5 is overlapped on the outside of the feed pipe 4, the delivery pipe 8 is connected to the feed pipe 4, and the sealing ring 19 is overlapped with the sealing ring 2 10.

[0024] By setting the slide groove 11 and the slide groove 2 12, when a thrust or a pull is applied to the sealing ring 1 9 and the sealing ring 2 10, the sealing ring 1 9 and the sealing ring 2 10 will slide in the slide groove 11 and the slide groove 2 12 respectively, so that the slide groove 11 and the slide groove 2 12 play a certain guiding role in the movement of the sealing ring 1 9 and the sealing ring 2 10, thereby preventing the sealing ring 1 9 and the sealing ring 2 10 from falling off from the feed pipe 4 and the conveying pipe 8 during movement.

[0025] like Figure 2 As shown, the concave plate 601 is fixedly connected to the top of the base 1, the motor 602 is fixedly connected to the top of the base 1, the guide rod 607 is rotatably connected to the support plate 2, the gear 604 is fixedly connected to one end of the guide rod 607, the gear 604 is engaged with the tooth plate 606, and the motor 602 drives the threaded rod 603 to rotate forward and reverse.

[0026] By setting the gear 604 and the tooth plate 606, when the motor 602 drives the threaded rod 603 to rotate, the movable plate 605 will slide on the surface of the threaded rod 603. Since the tooth plate 606 is engaged with the gear 604, the positioning plate 5 will flip around the guide rod 607, so that the feeding pipe 4 in connection can be automatically limited, avoiding the position deviation of the feeding pipe 4 when connected, and supporting the feeding pipe 4 in use.

[0027] like Figure 4 As shown, the positioning structure 7 includes an L-shaped plate 701 and a positioning rod 703. The positioning rod 703 is fixedly connected in the L-shaped plate 701. The positioning rod 703 is rotatably connected under the sealing ring 10. A groove 704 is provided in the L-shaped plate 701. A threaded rod 705 is rotatably connected in the groove 704. The threaded rod 705 is externally threadedly connected to a clamping plate 702. The clamping plate 702 overlaps with the sealing ring 9. The top of the threaded rod 705 is fixedly connected to a turntable 706. The clamping plate 702 is slidably connected in the groove 704.

[0028] By setting the positioning structure 7, the sealing ring 1 9 and the sealing ring 2 10 are fitted together and the L-shaped plate 701 is driven to rotate. When the position of the L-shaped plate 701 is adjusted, the turntable 706 drives the threaded rod 2 705 to rotate, and the clamping plate 702 moves on the surface of the threaded rod 2 705. After moving, the threaded rod 2 705 will contact the sealing ring 1 9, so that the sealing ring 1 9 and the sealing ring 2 10 can be quickly assembled, and the sealing ring 1 9 and the sealing ring 2 10 can be prevented from loosening due to external force.

[0029] The utility model provides a microchannel reactor, the specific working principle of which is as follows:

[0030] When the microchannel reactor is in use, the feeding tube 4 is placed above the support plate 2 and comes into contact with the delivery tube 8 and its microchannel body 13. The motor 602 drives the threaded rod 1 603 to rotate in the concave plate 601, and the movable plate 605 slides on the surface of the threaded rod 1 603. The tooth plate 606 moves along with the movable plate 605. Since the tooth plate 606 is engaged with the gear 604, the positioning plate 5 is flipped around the guide rod 607. After flipping, the positioning plate 5 overlaps with the support plate 2, and then the feeding tube 4 is limited.

[0031] When the feed pipe 4 is connected to the conveying pipe 8 and the microchannel body 13, the sealing ring 1 9 and the sealing ring 2 10 are fitted together, driving the L-shaped plate 701 to rotate around the positioning rod 703. After the position of the L-shaped plate 701 is adjusted, the turntable 706 drives the threaded rod 2 705 to rotate, and the clamping plate 702 moves on the surface of the threaded rod 2 705. After moving, the threaded rod 2 705 will contact the sealing ring 1 9, so that the sealing ring 1 9 and the sealing ring 2 10 can fit tightly.
