It should be noted that the tank 10 and the weld line a shown in fig. 2 use straight lines as schematic portions, and it is understood that the tank and the weld line should have an arc-shaped structure.

Due to the existence of the construction process, a circumferential circle of welding seam A is often present on the canned conventional island deaerator equipment. Because the equipment welded junction overhauls needs, the interval D of the equipment heat preservation support ring position from tank face welding seam A has definite regulation in the heat preservation technical requirement, and the support ring position needs 6.25 times wall thickness from both sides of welding seam for later maintenance. Therefore, if the support ring is moved to avoid the boss 30, the equipment weld 6.25 times spacing requirement needs to be met.

For fixing adjacent support rings 20 distributed along the circumferential direction of the can body 10, a protrusion 30 is provided on the circumferential surface of the can body 10, and the protrusion 30 partitions the adjacent support rings 20. As shown in fig. 2 and 3, the clip includes a pair of clamping plates 41, a plurality of connecting members 42, and at least one pair of wings 43.

A pair of clamping plates 41 are provided on both sides of the protruding member 30 to clamp part or all of the protruding member 30; a plurality of connection members 42 for connecting the pair of clamping plates 41, a part of the connection members 42 being fixedly or adjustably disposed adjacent to the boss 30, and the other part of the connection members 42 being adjustably disposed away from the boss 30 so that the spacing between the pair of clamping plates 41 can be adjusted; at least one pair of wing plates 43 are respectively fixed to the pair of clamping plates 41, the wing plates 43 extend in the circumferential direction of the support ring 20, and are used for fixedly connecting adjacent support rings 20 distributed in the circumferential direction at both sides of the clamping plates 41.

Specifically, in some embodiments, two rectangular steel plates are used for the clamping plate 41. The connecting member includes a pair of first bolts 421, a first nut 423 and a pair of second bolts 422, a second nut 424, the first bolts 421 being disposed adjacent to the boss 30 and fixedly or adjustably connected to the pair of clamping plates 41 by the first nuts 423, the second bolts 422 being engaged with the second nuts 424 to adjustably connect the pair of clamping plates 41 at intervals. The first bolt 421 and the first nut 423 are fixedly arranged to play a role of tensioning the clamping plate on one side, and the first bolt 421 and the first nut 423 are movably arranged to realize the adjusting function together with the second bolt 422 and the second nut 424.

The second bolt 422 on the outer side is adjusted to enable the surfaces of the two clamping plates 41 and the protruding piece 30 to be parallel to each other, so that the contact surface is maximized, and the stability of the clamp is ensured. Four bolts can be pre-tightened step by step in a divided manner, so that even stress of the bolts is ensured. It will be appreciated by those skilled in the art that the initial connection is typically performed by pre-tightening the nut to provide the initial positioning. After the positioning is determined, the first bolt 421 and the first nut 423 positioned at the inner side may be first tightened so that the clamping plate is tightened at the inner side.

In some embodiments, a ceramic fiber cloth is padded on the inside of the clamping plate 41 facing the protruding member 30 to protect the paint on the surface of the clamped object while increasing friction.

Specifically, if four holes are respectively perforated on the plane of the steel plate according to the positions of fig. 4 and 5, four sets of bolts are used for connection and fixation. The outer two second bolts 422 play a role in supporting and adjusting the interval, and the inner two first bolts 421 can play a role in tightening the clamping plates, that is, the inner two first nuts 423 can realize the tightening effect by tightening. The outer two second bolts 422 are movably adjustable, so that the cooperation of the outer second bolts 422 and the second nuts 424 determines the distance between the clamping plates 41, and further adjusts the distance between the two ends of the pair of wing plates 43. It will be appreciated that the first bolt 421 and the first nut 423 may also be provided in a movable adjustment manner to provide adjustment in conjunction with the second bolt 422 and the second nut 424.
