[0034] The detailed connection means is a technology known in the art, and the working principle and process are mainly introduced below. The specific work is as follows.

[0035] Step one: when the liquid level of the reaction kettle 1 is too high and overflows one end of the first liquid discharge pipe 53, the liquid enters the tank body 52 through the first liquid discharge pipe 53, and the liquid in the tank body 53 can enter the strip-shaped frame 57 through the through hole 58, so as to float the floating ball 510 upwards, until the floating ball 510 contacts the contact switch 511, and the contact switch 511 controls the electromagnetic valve 54 to start, so that the liquid filled in the tank body 53 can be discharged into the first collecting tank 56 through the second liquid discharge pipe 55 for collection, so as to avoid the increase of the internal pressure of the reaction kettle;

[0036] Step two: when the first overflow mechanism cannot meet the discharge of the liquid in the reactor 1, the liquid level in the reactor 1 continues to rise, which causes the liquid pressure to be too large to extrude the pressing plate 65 through the connecting pipe 61, so that the pressing plate 65 extrudes the spring 66 under the limitation of the guide column 67 and the guide rod 68, so that the pressing plate 65 can be separated from one side of the cylindrical shell 62 to unseal one side of the cylindrical shell 62, and then the liquid in the reactor 1 can flow into the cylindrical shell 62 and then be discharged into the second collecting tank 64 through the third liquid discharge pipe 63, so that the liquid level in the reactor 1 can be quickly lowered, thereby avoiding the risk of overflow and avoiding the rupture of the container caused by the increase of the internal pressure, and the safety is high.

[0037] Step three:

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
