[0035] Among them, sealing strips are provided at the edges of the plugging plate A5 and the plugging plate B8, and the material of the sealing strip is rubber. By setting the sealing strip, when the plugging plate A5 or the plugging plate B8 is moved into the inside of the avoidance groove 2, the gap can be sealed by the sealing strip to prevent the substances in the avoidance groove 2 from leaking out;

[0039] Embodiment Two:

[0040] Please refer to Figure 1-6 , on the basis of Embodiment One, this embodiment provides a technical solution: The stability maintenance assembly 10 includes a carrier frame 20, a displacement slide bar 21, a locking block 22, a limiting piece 23 and a spiral spring 24. The middle part of the top end of the esterification reactor main body 1 is fixedly connected with the carrier frame 20. The four corners of the carrier frame 20 are slidably connected with the displacement slide bars 21. The two ends of the displacement slide bar 21 are respectively fixedly connected with the locking block 22 and the limiting piece 23, and the limiting piece 23 is snap-connected with the stability maintenance seat 11. A spiral spring 24 is fixedly connected between the limiting piece 23 and the carrier frame 20;

[0041] Here, pressure-receiving slopes are provided at both the top and bottom of the locking block 22. A lock-matching groove is formed in the middle of the stability-maintaining seat 11, and the locking block 22 is snap-connected inside the lock-matching groove. With the provision of the pressure-receiving slopes, when the plugging plate A5 or the plugging plate B8 or the stability-maintaining seat 11 passes by the locking block 22, it can contact the pressure-receiving slopes, and through the linear displacement of the plugging plate A5 or the plugging plate B8 or the stability-maintaining seat 11, the pressure-receiving slopes are pushed, prompting the displacement of the locking block 22 to avoid interference with the displacement of the plugging plate A5. And when the locking block 22 corresponds to the lock-matching groove, the resilience of the spiral spring 24 can drive the locking block 22 to snap into the lock-matching groove, thereby providing auxiliary support for the plugging plate A5 or the plugging plate B8.

[0042] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0043] During operation, pour the butyl acrylate raw material into the esterification reactor main body 1, connect the external liquid pipeline to the spray pipe 7, and carry out esterification reaction through the esterification reactor main body 1. When the inner wall of the esterification reactor main body 1 needs to be cleaned subsequently, first start the drive motor 19 to drive the central shaft rod 13 connected thereto to rotate. With the setting of the two linkage spur gears 17, the power of the central shaft rod 13 can be transmitted, prompting the two central shaft rods 13 to rotate simultaneously to drive the eccentric drive plate 14 to flip. Under the connection between the eccentric drive plate 14 and the extension seat 16, the extension seat 16 can follow the flip of the eccentric drive plate 14, driving the plugging plate A5 to displace under the limitation of the displacement frame 4, prompting the plugging plate B8 to move out of the avoidance groove 2 until the spray pipe 7 moves into the esterification reactor main body 1, and at the same time using the plugging plate A5 to plug the avoidance groove 2;

[0044] And when the stability-maintaining seat 11 moves downward, it can drive the displacement of the locking block 22 by the contact between the plugging plate A5 and the plugging plate B8 and the locking block 22 until the locking block 22 corresponds to the lock-matching groove. Subsequently, the resilience of the spiral spring 24 will prompt the locking block 22 to snap into the lock-matching groove to provide auxiliary support for the plugging plate A5 or the plugging plate B8;

[0045] The liquid conveyed by the liquid pipeline will be injected into the spray pipe 7 and sprayed onto the inner wall of the esterification reactor main body 1 through the spray pipe 7 to clean the inner wall of the esterification reactor main body 1.
