[0045] The mounting rod 5 passes through the inner side of the plate mounting hole of the microchannel reactor 2, plays a role in positioning the plate, ensures the alignment of the mounting hole, and prevents the material from flowing unsmoothly.

[0046] When in normal use, the end of the mounting rod 5 away from the vertical rod 101 is located on the inner side of the linear bearing. When the microchannel reactor 2 needs to be disassembled for maintenance, the end of the mounting rod 5 away from the vertical rod 101 is not located on the inner side of the linear bearing.

[0047] The microchannel reactor 2 is a plurality of stacked plates, each of which is provided with a reaction groove, and both ends of the reaction groove are connected to mounting holes. There are four mounting holes corresponding to four mounting rods 5 .

The spherical surface of the screw rod 4 contacts the bottom end of the positioning groove 303, and grease for lubrication is provided between the two. The structure of the positioning groove 303 plays a positioning role for the screw rod 4 to prevent it from moving in the process of pushing the push plate 3. The outer wall of the force-bearing column 302 is fixedly connected to the push plate 3 through a reinforcing rib 304, and the reinforcing rib 304 improves the structural strength of the push plate 3.

There are two screw rods 4.

[0050] In other embodiments, the driving component is a pneumatic cylinder or an electric cylinder.

[0051] A guide tube 305 matching the bottom frame 1 is fixedly provided at the lower end of the push plate 3. The guide tube 305 is installed on the outer side of the bottom frame 1. The guide tube 305 not only guides the push plate 3 during its movement, but also supports the mounting rod 5 when the sliding hole 301 of the push plate 3 is located on one side of the mounting rod 5, thereby preventing the mounting rod 5 from deforming.

[0052] A sealing column 306 corresponding to the material hole 201 of the microchannel reactor 2 is fixedly arranged on the end surface of the push plate 3 adjacent to the microchannel reactor 2, the diameter of the sealing column 306 matches the diameter of the material hole 201, and the sealing column 306 is located on the inner side of the material hole 201; an annular sealing groove is opened on the end surface of the push plate 3 adjacent to the microchannel reactor 2, the annular sealing groove is located on the outer side of the sealing column 306, a sealing ring 307 is arranged in the annular sealing groove, and the sealing ring 307 is located between the bottom end of the annular sealing groove and the microchannel reactor 2. The sealing ring 307 improves the sealing between the push plate 3 and the microchannel reactor 2 to prevent material leakage. A baffle 6 is fixedly arranged on the vertical rod 101 on which the push plate 3 is mounted with a mounting column, and a material pipe 601 is fixedly arranged on the baffle 6. The outer diameter of the material pipe 601 matches the diameter of the material hole 201 of the microchannel reactor 2, and the material pipe 601 is located on the inner side of the material hole 201; a sealing gasket 602 is arranged between the baffle 6 and the microchannel reactor 2, and the sealing gasket 602 is located on the outer side of the material pipe 601. The sealing gasket 602 improves the sealing between the material pipe 601 and the microchannel reactor 2 to prevent material leakage.

[0053] A support plate 7 is provided between the microchannel reactor 2 and the bottom frame 1. The upper end surface of the support plate 7 is an arc-shaped surface. The support plate 7 is a structural member made of polytetrafluoroethylene. A plug post 701 is fixedly provided at the lower end of the support plate 7. A plug hole 104 matching the plug post 701 is provided on the bottom frame 1. The plug post 701 is detachably connected to the inner side of the plug hole 104. The support plate 7 supports the lower end surface of the microchannel reactor 2 to prevent the mounting rod 5 from being deformed by the gravity of the microchannel reactor 2. A support leg 102 is fixedly provided at the bottom end of the bottom frame 1.

[0054] Working process:

[0055] During the implementation of this scheme, when the microchannel reactor 2 needs to be maintained, the screw 4 is first loosened. At this time, the push plate 3 can move in the direction away from the mounting rod 5. At this time, each plate can be removed for cleaning and maintenance. After cleaning, the mounting hole of the plate is aligned with the mounting rod 5 and inserted. There are two baffles 6, which are respectively inserted into the material holes 201 at both ends of the reaction tank of the first plate, and then other plates are installed in turn. The adjacent plates close the opening of the reaction tank to form a reaction channel. Finally, the screw 4 is used to drive the push plate 3 to move and tighten the plate away from the end of the baffle 6 to eliminate the gap between the plates and ensure the sealing of the reaction channel.

[0056] One material pipe 601 is used as a feed pipe to take in materials, and the other material pipe 601 is used as a discharge pipe to discharge materials. The movable setting of the push plate 3 can not only eliminate the gaps between the plates, but also increase the speed of the maintenance process of the microchannel reactor 2 and improve the work efficiency.
