[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment: As Figures 1-5 shown, the present invention provides a reaction kettle sealing device in the production of oilfield chemical additives, including a kettle body 1. A top cover 11 is provided at the top of the kettle body 1. A first mounting plate 12 is fixedly provided at the bottom of the top cover 11. A first groove 13 is opened on the lower surface of the first mounting plate 12. The first groove 13 is circularly arranged. A first sealing washer 14 is provided in the first groove 13. A second mounting plate 15 is fixedly provided at the top end of the kettle body 1. A second sealing washer 16 is provided on the upper surface of the second mounting plate 15. The first sealing washer 14 can be in close contact with the second sealing washer 16;

[0020] A support plate 2 is fixedly provided on the outer wall of the kettle body 1 below the second mounting plate 15. Fixed seats 21 are fixedly distributed annularly on the upper surface of the support plate 2. The fixed seats 21 are L-shaped. Two symmetrically distributed limiting plates 22 are fixedly provided on the vertical end of the fixed seat 21 and on the side far from the kettle body 1. A moving block 23 is slidably provided between the two limiting plates 22. The side of the moving block 23 far from the kettle body 1 is wedge-shaped. A positioning plate 24 is rotatably provided on the vertical end of the fixed seat 21 and above the two limiting plates 22. A sliding wheel 25 is rotatably provided at the bottom of the positioning plate 24 and the sliding wheel 25 abuts against the inclined surface of the moving block 23. A protruding positioning block 241 is fixedly provided at the end of the positioning plate 24 far from the sliding wheel 25. A lead screw 26 is threadedly inserted into the bottom of the moving block 23. The bottom of the lead screw 26 penetrates through the support plate 2.

[0021] The upper surface of the outer wall of the first mounting plate 12 is provided with a positioning groove 121, which is correspondingly arranged with the positioning block 241. The setting of the positioning groove 121 can ensure that the positioning block 241 on the positioning plate 24 stably abuts against the first mounting plate 12 and the top cover 11, thereby ensuring the sealing performance between the top cover 11 and the top of the kettle body 1.

[0022] The self-weight of the sliding wheel 25 is greater than the weight of the positioning plate 24, which can make the lifted positioning plate 24 automatically abut against the inclined surface of the moving block 23 due to the gravity of the sliding wheel 25 subsequently. The bottom of the first mounting plate 12 can be fittedly sleeved on the second mounting plate 15. The fitting sleeve between the first mounting plate 12 and the second mounting plate 15 can increase the sealing effect between the kettle body 1 and the top cover 11.

[0023] A chute 4 is provided on the vertical side of the fixed seat 21. A slider 41 is slidably arranged in the chute 4. One end of the slider 41 is fixedly connected to the moving block 23. An activity plate 42 is provided between the support plate 2 and the second mounting plate 15 on the outer wall of the kettle body 1. A sealing plate 43 is provided on the upper surface of the activity plate 42. Through the slider 41 and the activity plate 42, the sealing plate 43 can move upward together with the moving block 23. At this time, the activity plate 42 can seal the bottoms of the first mounting plate 12 and the second mounting plate 15, thereby completely sealing between the top cover 11 and the kettle body 1, greatly improving the sealing performance of the kettle body 1.

[0024] The bottom of the lead screw 26 is fixedly provided with a rotating shaft 27. A synchronous pulley 3 is fixedly provided on the rotating shaft 27. The synchronous pulleys 3 on multiple rotating shafts 27 are jointly driven and sleeved with a synchronous belt 31. The setting of the synchronous pulley 3 and the synchronous belt 31 can simultaneously drive the synchronous rotation of multiple annularly distributed rotating shafts 27, increasing the linkage of the device and facilitating the operation of the staff. A support block 29 is provided on the outer wall of the kettle body 1 near the rotating shaft 27. The rotating shaft 27 is rotatably arranged on the support block 29. The setting of the support block 29 can support the rotating shaft 27, thereby ensuring the stable rotation of the rotating shaft 27. One of the rotating shafts 27 penetrates through the support block 29 and is fixedly provided with a runner 28. The setting of the runner 28 can facilitate the staff to drive the lead screw 26 to work, thereby driving the fixation between the top cover 11 and the kettle body 1 and facilitating the operation of the staff.

[0025] Working principle: When in use, the bottom of the first mounting plate 12 is clamped inside the second mounting plate 15. At this time, the first mounting plate 12 and the second mounting plate 15 will be clamped together in a fitting manner. At this time, the staff can directly drive the rotation of the rotating shaft 27 through the rotating wheel 28. The synchronous wheels 3 and the synchronous belt 31 are provided to drive multiple rotating shafts 27 to rotate synchronously at the same time. At this time, the rotating shaft 27 will drive the screw rod 26 to rotate. The moving block 23 threaded on the screw rod 26 will move upward. The upward moving moving block 23 will push the sliding wheel 25 to drive the positioning plate 24 to swing. The positioning block 241 fixedly arranged at the top end of the positioning plate 24 will be clamped in the positioning groove 121 opened on the first mounting plate 12, completing the installation between the kettle body 1 and the top cover 11. At this time, the first sealing gasket 14 will move downward and closely abut against the second sealing gasket 16, filling the gap between the first mounting plate 12 and the second mounting plate 15. At the same time, as the moving block 23 moves upward, the sealing plate 43 can move upward together with the moving block 23 through the slider 41 and the movable plate 42. At this time, the movable plate 42 can close the bottoms of the first mounting plate 12 and the second mounting plate 15, thus completely sealing between the top cover 11 and the kettle body 1, greatly improving the sealing performance of the kettle body 1, ensuring the sealing effect during the operation of the reaction kettle, and improving the reaction efficiency.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these changes and modifications.
