Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and in particular to a hydraulic mechanical anti-detachment structure for the discharge port of a thermal polymerization reactor. Background Technology

[0002] In chemical production, the inner wall and the edge of the vessel opening of most reaction vessels are made of enamel. The vessel opening cover is connected to the vessel body by a connecting mechanism. After the vessel opening cover is opened, it can only be fixed to one side. Because the vessel opening cover itself is very heavy, coupled with the large-scale material of the thermal polymerization reaction, it all accumulates on the top of the vessel opening cover at the discharge port during the reaction process. Therefore, it adds a lot of load pressure to the vessel opening cover. Once the traditional hydraulic device fails or is damaged, it will directly cause the vessel opening cover at the discharge port to open, the material to fall prematurely, the thermal polymerization reaction to be incomplete, and the material to be wasted.

Then, the hydraulic push rod 53 is activated to push the sliding plate 51 on the positioning column 46 to move upward on the seat plate 47. At this time, the sliding plate 51 drives the fixed shaft seat 54 to rise, and the linkage rod 55 rotates around the fixed shaft seat 54, thereby pushing the pin 56 to slide in the cavity between the limiting cover plate 44 and the limiting strip 42 until the pin 56 is inserted and locked with the bracket group 2 to prevent hydraulic failure of the hydraulic rod 34. The entire kettle cover body 41 opens from the discharge port 1 to ensure the completion of the thermal polymerization reaction.
