Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a device for dividing the outlet of a thermal polymerization reactor. Background Technology

[0002] Thermal polymerization refers to the process in which monomer molecules acquire sufficient energy through heating without the addition of an external initiator, thereby initiating a polymerization reaction to form a high molecular weight compound. This reaction belongs to the category of free radical polymerization, in which monomer molecules are excited into free radicals at high temperatures, which in turn initiate a chain polymerization reaction.

[0003] After the high-temperature polymerization reaction, the materials need to be transported to the next processing stage. Since the polymerized substances are mostly viscous liquids, semi-solids, or solids, large-scale production of the reaction materials will result in the formation of large clumps. These clumps are not conducive to subsequent transportation, so they need to be divided and cut. Common dividing and cutting devices are mostly independent steps, which affects the processing time of the process and greatly reduces the efficiency of work, increasing the cost of thermal polymerization.
