[0018] 1. The epichlorohydrin storage tank that is easy to open described in the present invention is provided with a connecting assembly and a driving assembly so as to quickly assemble the upper tank body and the lower tank body together. When in use, the flange one and the flange two are first aligned, and the locking bolt is passed through the through holes on the sealing ring and the flange one, and the top of the locking bolt is abutted against the threaded hole on the pressure ring. Then, the locking bolt is driven to rotate by the driving assembly so that the pressure ring is threadedly connected to the locking bolt. The locking bolt is continuously rotated so that the pressure ring moves to be pressed against the top of the flange one, and then the flange one and the flange two can be tightly pressed against the two sides of the sealing ring to complete the installation. When the driving assembly is made to move in the reverse direction, the upper tank body and the lower tank body can be separated. The operation is simple, and the storage tank body can be quickly disassembled and assembled by rotating the driving assembly, thereby improving the disassembly and assembly efficiency.

[0019] 2. The epichlorohydrin storage tank that is easy to open described in the present invention prevents the driving ring from being accidentally touched by the outside world by setting an anti-mistouch component, which causes the connection between the upper tank body and the lower tank body to loosen. When it is needed to use the driving component to drive the locking bolt to rotate during use, the driving ring is pressed downward first, and the spring 2 is compressed at this time. After the driving ring moves downward, the push block at the bottom can contact the stop block. When the driving ring is rotated, the driving ring, the push block and the stop block cooperate to drive the rotating frame to rotate, thereby driving the gear below to rotate, and finally driving the locking bolt to rotate for disassembly and assembly. In addition, when the driving ring is no longer pressed downward, the driving ring is pushed upward under the rebound action of the spring 2, and the push block is simultaneously driven to move up to the top of the stop block. At this time, the push block will not contact the stop block, which can prevent the driving ring from accidentally rotating due to external touch, so that the upper tank body and the lower tank body remain stable after sealing and installation.
