[0002] Initiators play an important role in the preparation and processing of polymers. They can initiate free radical, ionic and other chain liquid phase polymerization reactions, activate the reaction center on the monomer molecule, accelerate the reaction rate, and promote the combination of monomer molecules to form polymers. Generally, the initiators are added to the reaction tank to promote the occurrence of polymerization reaction by manual feeding or using a funnel. However, the manual feeding or the use of the funnel cannot accurately control the dosage and cannot guarantee the quality of the generated polymer. CONTENT OF THE UTILITY MODEL

The amount of initiator in the hopper is monitored in real time by the liquid level meter. When the amount of initiator in the hopper is too small, the alarm sends an alarm to prompt the staff to add an appropriate amount of initiator to the hopper, thereby ensuring that the amount of initiator in the hopper is sufficient and avoiding the influence of insufficient amount of initiator on the polymerization reaction.
