Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tetrahydrofuran polymerization catalysts, in particular to a circulating reaction device for high-purity tetrahydrofuran polymerization catalysts and a polymerization process. BACKGROUND

[0002] The tetrahydrofuran polymerization catalyst refers to a chemical substance capable of catalyzing the polymerization reaction of tetrahydrofuran monomers under specific conditions. The catalyst plays a crucial role in the polymerization process, as it can accelerate the bonding between tetrahydrofuran molecules, thereby efficiently generating high-molecular-weight polytetrahydrofuran. High-purity tetrahydrofuran polymerization catalysts are essential for ensuring the quality and performance of the polymerization product. Therefore, the purity and activity of the catalyst need to be strictly controlled during preparation and application.

[0003] According to the patent document CN120054325A, a catalyst preparation device is disclosed. A plurality of upper pressing pieces are arranged on the circumference of the rotating disc. The upper pressing pieces are in sliding connection with the rotating disc. A top rod corresponding to the upper pressing pieces is slidably arranged on the rotating disc. An upper guide piece and a lower guide piece are arranged on the base frame. The rotating disc has an extrusion cavity cooperating with the upper pressing pieces and the top rod. A rod one is slidably arranged in the upper pressing piece. A limiting rod cooperating with the upper pressing piece is slidably arranged on the rod one. An unlocking rod cooperating with the limiting rod is slidably arranged on the upper pressing piece. A rod two is slidably arranged in the top rod. An upper top ring and a lower top ring are slidably arranged on the base frame. A driving piece is arranged on the base frame to drive the upper top ring to move. When the upper top ring moves downward, the upper top ring can stop the unlocking rod to make the rod one and the upper pressing piece disengage. The lower top ring can move upward and stop the rod two to make the rod two extend out of the top rod. The present application is beneficial for efficiently and multi-form pressing of catalyst particles.
