Description

Technical Field

[0001] The present utility model design relates to the technical field of reactors, and particularly to a movable fixing device for a hollow reactor. Background Art

[0002] Traditional reactor fixing devices usually need to firmly fix the reactor in the placement position by bolts, buckles, welding or other means. Once fixed, it becomes very difficult to move or adjust the position of the reactor again. This is because the structural design of the fixing device makes the reactor tightly connected to the supporting components and difficult to untie or disassemble. This fixing method not only consumes time and human resources, but also may cause damage or loss of the device, as well as delays and inconveniences during the working process.

[0003] Therefore, a new type of device is needed that can make the reactor move more conveniently during testing and after installation without the need for fixed installation. Summary of the Utility Model
