The quick-opening laboratory reaction kettle mainly features a triangular sealing design between the kettle body and the kettle lid. The quick-opening reaction kettle utilizes a quick-opening lid structure between the kettle body and lid. The kettle body and lid are sealed using a quick-opening clamping ring for flange connection, which can be sealed by simply tightening the bolts on the kettle lid. This results in short lifting and opening times, making operation convenient. It can also be upgraded to lift the kettle lid by rotating the lifting handwheel on the equipment to turn the screw, allowing the lid to be moved to the side for easy addition of materials, discharge, and cleaning. Handles are provided on the stand, allowing the kettle body to be rotated 120 degrees around the horizontal axis for convenient pouring and cleaning of residues. The heating furnace can be easily and quickly mounted and removed, offering ease of operation and enhanced safety. Its ability to meet complex process pipeline configuration requirements has made it highly favored by a wide range of users.
