The reactor body is provided with a sealing ring and a ring groove for mounting the sealing ring on the wall of the reaction chamber.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figures 1-10A highly sealed column microchannel reactor includes a reactor body 1, a liquid outlet pipe 2 and a liquid inlet pipe 4. The inner wall of the reactor body 1 is fixedly connected to the side wall of the liquid outlet pipe 2. The inner wall of the reactor body 1 is connected to a diverter plate 3 through a connecting mechanism. The side wall of the diverter plate 3 and the side wall of the liquid inlet pipe 4 are connected by a flange.

[0022] The sealing mechanism includes a hollow sealing ring 5 fixedly embedded in the inner wall of the reactor body 1 away from the liquid outlet pipe 2, and a sealing groove 6 (such as Figure 4 As shown in FIG), the side wall of the reactor body 1 is fixedly connected to an oil storage frame 7, and the inner wall of the oil storage frame 7 is sealed and slidably connected to a first plate 8 (as shown in FIG). Figure 8 As shown), the side wall of the first plate 8 is elastically connected to the inner wall of the oil storage frame 7 through multiple first springs 9, and the inner wall of the oil storage frame 7 is connected to the inner wall of the hollow sealing ring 5 through the first tube 10 (as shown Figure 5 shown).

[0023] A hollow sealing ring 5 and a sealing groove 6 are provided. After the diverter disc 3 is connected and installed in the reactor body 1, the hollow sealing ring 5 and the sealing groove 6 are facing each other. At this time, the hydraulic oil on the inner wall of the oil storage frame 7 can enter the hollow sealing ring 5 through the first tube 10, so that the hollow sealing ring 5 expands and is stuck in the sealing groove 6, thereby achieving a seal between the side wall of the diverter disc 3 and the inner wall of the reactor body 1. Under the action of the hydraulic oil, the sealing stability is high, avoiding the prior art of achieving the sealing in the reaction chamber by the resistance between the sealing ring and the side wall of the disc body, which is easy to fail due to aging, deformation or excessive pressure in the reaction chamber, resulting in a decrease in the sealing performance in the reaction chamber, thereby affecting the effect of the chemical reaction in the reaction chamber.

[0024] The connection mechanism includes a plurality of clamping rods 11 that are sealed and slidably connected to the inner wall of the reactor body 1, and a plurality of clamping grooves 12 (such as Figure 4 shown).

[0025] The side wall of the reactor body 1 is fixedly connected to a plurality of second plates 13 corresponding one to one with the plurality of clamping rods 11, and the side walls of the plurality of second plates 13 are slidably connected to the first rod 14. The side wall of the first rod 14 is rotatably connected to the upper end of the corresponding clamping rod 11 through the second rod 15. The side wall of the first rod 14 away from the second rod 15 is fixedly connected to the first wedge plate 16, and the side wall of the first wedge plate 16 is elastically connected to the side wall of the second plate 13 through a plurality of second springs 17.

[0026] A third rod 18 is fixedly connected to the side wall of one of the first wedge plates 16 close to the second spring 17, and a fourth rod 19 is fixedly connected to the side wall of the first plate 8 away from the first spring 9, which is opposite to the third rod 18. The third rod 18 abuts against the fourth rod 19 during movement.

[0027] The side wall of the reactor body 1 is provided with an annular groove 20 (such as Figure 7 As shown in the figure, a rotatable ring 21 is slidably connected to the inner wall of the annular groove 20, and a plurality of second wedge plates 22 corresponding to the first wedge plates 16 are fixedly connected to the side wall of the ring 21 close to the second plate 13. The plurality of second wedge plates 22 fit together with the plurality of first wedge plates 16 during the rotation process, and a plurality of hand levers 23 are fixedly connected to the side wall of the ring 21 away from the second plate 13.

[0028] When the diverter plate 3 is completely inserted into the reactor body 1 and the side wall of the diverter plate 3 is flush with the side wall of the reactor body 1, the ring 21 is rotated forward by the multiple hand levers 23, so that the multiple second wedge plates 22 rotate and fit into the multiple first wedge plates 16, driving the multiple first wedge plates 16 to move toward the side walls of the multiple second plates 13 respectively. At this time, the multiple first wedge plates 16 drive the multiple clamping rods 11 to approach each other through the multiple first rods 14 and the multiple second rods 15, and the multiple clamping rods 11 respectively enter the multiple clamping grooves 12, thereby fixing the position of the diverter plate 3. At the same time, when one of the first wedge-shaped plates 16 moves toward the side wall close to the second plate 13, the third rod 18 will be pressed against the fourth rod 19, thereby driving the first plate 8 to slide in the oil storage frame 7, and squeezing the hydraulic oil on the inner wall of the oil storage frame 7 into the hollow sealing ring 5 through the first tube 10, thereby achieving a seal between the side wall of the diverter plate 3 and the inner wall of the reactor body 1, preventing the gas generated during the chemical reaction from overflowing, and thus achieving a sealing effect while realizing the connection and installation between the diverter plate 3 and the reactor body 1, simplifying the operation steps and improving the sealing performance.

[0029] A sealing ring 36 with an L-shaped cross-section is fixedly connected to the inner wall of the reactor body 1, and a fixing ring 37 is fixedly connected to the side wall of the sealing ring 36 away from the diverter plate 3. A plurality of second through grooves 38 corresponding to the plurality of first rods 14 are provided on the side wall of the reactor body 1. Two slide grooves 39 are provided on the inner walls of the plurality of second through grooves 38. A slide plate 40 is sealingly and slidingly connected between the inner walls of the two slide grooves 39. The side wall of the slide plate 40 is fitted with the inner wall of the second through groove 38. An L-shaped rod 41 is fixedly connected to the side wall of the slide plate 40. The upper end of the L-shaped rod 41 is fixedly connected to the side wall of the corresponding first rod 14, and the end of the L-shaped rod 41 away from the first rod 14 is fixedly connected to the side wall of the fixing ring 37.

[0030] It should be noted that the inner walls of the two chutes 39 away from the second through groove 38 are both provided with through holes communicating with the side wall of the reactor body 1 to balance the pressure changes in the two chutes 39 during the sliding process of the slide plate 40.

[0031] When the multiple first wedge plates 16 move toward the side walls of the multiple second plates 13 and drive the multiple first rods 14 to move, the multiple first rods 14 drive the fixing ring 37 to move toward the direction close to the diverter plate 3 through the multiple L-shaped rods 41 and the slide plate 40, so that the side wall of the L-shaped sealing ring 36 fits tightly with the side wall of the diverter plate 3, thereby preventing the gas generated by the chemical reaction in the reactor body 1 from overflowing. Compared with the prior art in which the sealing of the reactor body 1 is achieved by the abutment between the sealing ring 36 and the side wall of the diverter plate 3, the present technical solution applies pressure to the sealing ring 36 to improve the sealing effect.

[0032] The side walls of the circular ring 21 on both sides of one of the second plates 13 are both provided with first through grooves 24 , and the inner side walls of the annular groove 20 located in the two first through grooves 24 are both threadedly connected with threaded rods 25 .

[0033] After the multiple clamping rods 11 enter the multiple clamping grooves 12 respectively, the two threaded rods 25 are respectively threadedly connected to the inner wall of the annular groove 20 through the two first through grooves 24. At this time, the two threaded rods 25 can limit the rotation position of the ring 21. Since the fitting surface between the second wedge plate 22 and the first wedge plate 16 is large, when the ring 21 rotates back and forth between the two threaded rods 25, it will not cause the second wedge plate 22 and the first wedge plate 16 to separate, and will not affect the connection and installation stability of the diverter plate 3.

[0034] An annular cavity 26 is formed on the inner wall of the reactor body 1 near the liquid outlet pipe 2 . A temperature sensing head 27 is fixedly connected to the inner wall of the annular cavity 26 . A temperature sensing agent is provided in the annular cavity 26 .

[0035] The temperature sensing head 27 can sense the temperature inside the reactor body 1 through the temperature sensing agent, which is convenient for subsequent temperature control during the chemical reaction in the reactor body 1 .

[0036] A mixing mechanism is provided in the annular cavity 26 , and the mixing mechanism includes a plurality of cross bars 28 rotatably connected to the inner wall of the annular cavity 26 in a sealed manner, and a plurality of mixing rods 29 are fixedly connected to the side walls of the plurality of cross bars 28 .

[0037] The inner wall of the annular groove 20 is provided with a plurality of grooves 30 corresponding to the plurality of cross bars 28. The tops of the plurality of grooves 30 are rotatably connected to vertical bars 31, and the lower ends of the plurality of vertical bars 31 are fixedly connected to first bevel gears 32. The side walls of the plurality of cross bars 28 pass through the side walls of the reactor body 1 and extend into the plurality of grooves 30. The side walls of the cross bars 28 located in the grooves 30 are fixedly connected to second bevel gears 33, and the side walls of the first bevel gear 32 are meshed with the side walls of the corresponding second bevel gears 33.

[0038] The upper ends of the multiple vertical rods 31 are fixedly connected to bevel gears 35, and the side wall of the ring 21 close to the hand lever 23 is fixedly connected to multiple arc-shaped bevel gear rings 34 corresponding to the multiple bevel gears 35. The side walls of the bevel gears 35 are meshed with the side walls of the corresponding arc-shaped bevel gear rings 34.

[0039] When the ring 21 rotates back and forth between the two threaded rods 25, the multiple arc-shaped bevel gear rings 34 drive the multiple bevel gears 35 to rotate forward and reverse, and then drive the multiple mixing rods 29 to rotate through the multiple vertical rods 31, multiple first bevel gears 32, multiple second bevel gears 33 and multiple cross rods 28, so as to evenly mix the temperature sensitive agent in the annular cavity 26, so that the temperature distribution on the temperature sensitive agent is uniform, which facilitates the temperature sensing head 27 to accurately sense the temperature inside the reactor body 1.

[0040] Before using the column microchannel reactor, the diverter plate 3 is first placed in the reactor body 1, and when the side wall of the diverter plate 3 is flush with the side wall of the reactor body 1, the ring 21 is rotated forward by the multiple hand levers 23, so that the multiple second wedge plates 22 rotate and fit into the multiple first wedge plates 16, driving the multiple first wedge plates 16 to move toward the side walls of the multiple second plates 13 respectively. At this time, the multiple first wedge plates 16 drive the multiple clamping rods 11 to approach each other through the multiple first rods 14 and the multiple second rods 15, and the multiple clamping rods 11 respectively enter the multiple clamping grooves 12, thereby fixing the position of the diverter plate 3; After the diverter disc 3 is connected and installed in the reactor body 1, the hollow sealing ring 5 and the sealing groove 6 are aligned, and when one of the first wedge-shaped plates 16 moves toward the side wall close to the second plate 13, the third rod 18 will be pressed against the fourth rod 19, thereby driving the first plate 8 to slide in the oil storage frame 7, and the hydraulic oil on the inner wall of the oil storage frame 7 is squeezed into the hollow sealing ring 5 through the first pipe 10, thereby achieving a seal between the side wall of the diverter disc 3 and the inner wall of the reactor body 1, thereby achieving a sealing effect while achieving the connection and installation between the diverter disc 3 and the reactor body 1, simplifying the operation steps and improving the sealing performance; When the multiple first wedge-shaped plates 16 move toward the side walls of the multiple second plates 13 and drive the multiple first rods 14 to move, the multiple first rods 14 drive the fixing ring 37 to move toward the direction close to the diverter plate 3 through the multiple L-shaped rods 41 and the slide plate 40, so that the side wall of the L-shaped sealing ring 36 is tightly fitted with the side wall of the diverter plate 3, thereby preventing the gas generated by the chemical reaction in the reactor body 1 from overflowing. Compared with the prior art in which the sealing of the reactor body 1 is achieved by the abutment between the sealing ring 36 and the side wall of the diverter plate 3, the present technical solution applies pressure to the sealing ring 36 to improve the sealing effect. After the multiple clamping rods 11 are respectively inserted into the multiple clamping grooves 12, the two threaded rods 25 are respectively threadedly connected to the inner wall of the annular groove 20 through the two first through grooves 24. At this time, the two threaded rods 25 can limit the rotation position of the ring 21. Since the contact surface between the second wedge plate 22 and the first wedge plate 16 is large, when the ring 21 rotates back and forth between the two threaded rods 25, the second wedge plate 22 and the first wedge plate 16 will not be separated, and the connection and installation stability of the diverter plate 3 will not be affected. Subsequently, the external liquid reactants enter the reactor body 1 through the liquid inlet pipe 4 and the diverter plate 3, and are discharged from the reactor body 1 through the liquid outlet pipe 2 after the reaction. At this time, the temperature sensing head 27 can sense the temperature inside the reactor body 1 through the temperature sensing agent, which is convenient for the subsequent control of the temperature during the chemical reaction in the reactor body 1. In this process, the ring 21 can be intermittently rotated back and forth between the two threaded rods 25. At this time, the multiple arc-shaped bevel gear rings 34 drive the multiple bevel gears 35 to rotate forward and backward, and then drive the multiple mixing rods 29 to rotate through the multiple vertical rods 31, multiple first bevel gears 32, multiple second bevel gears 33 and multiple cross rods 28, so as to evenly mix the temperature sensing agent in the annular cavity 26, so that the temperature distribution on the temperature sensing agent is uniform, which is convenient for the temperature sensing head 27 to accurately sense the temperature inside the reactor body 1.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
