Figure 1 and Figure 2 As shown, the bracket structure includes: a first bracket 1, a second bracket 2, a third bracket 3, a first support ear 4, a second support ear 5 and a third support ear 6; wherein: the first bracket 1 is horizontally placed and located at the front and rear sides of the small pressure vessel, the first support ear 4 is arranged on the side wall of the large pressure vessel, and the first bracket 1 is fixedly connected to the large pressure vessel through the first support ear 4 on the side away from the small pressure vessel; the second bracket 2 is horizontally placed and located at the left and right sides of the small pressure vessel, and the front and rear ends of the second bracket 2 are fixedly connected to the first bracket 1 (for example, the front and rear ends of the second bracket 2 are fixedly connected to the first bracket 1 by welding); the first bracket 1 and the second bracket 2 keep the small pressure vessel stable through the second support ear 5 (for example, keep the small pressure vessel fixed or move only within a limited range); the third bracket 3 is tilted, the third support ear 6 is arranged on the side wall of the large pressure vessel and located below the first support ear 4, one end of the third bracket 3 is fixedly connected to the side of the first bracket 1 close to the small pressure vessel (for example, the third bracket 3 is detachably connected to the first bracket 1 by bolts and nuts), and the other end of the third bracket 3 is fixedly connected to the large pressure vessel through the third support ear 6. As used herein, a "large pressure vessel" refers to a pressure vessel with a relatively high pressure and a relatively large diameter, and a "small pressure vessel" refers to a pressure vessel with a relatively low pressure and a relatively small diameter. The support structure provided in the present application can be used to stabilize a small pressure vessel near a large pressure vessel, wherein the first support 1 and the second support 2 surround the small pressure vessel and play a major stabilizing role, and the two ends of the third support 3 are respectively connected to the first support 1 and the large pressure vessel to form a triangular structure, further improving the stability of the entire support structure.

[0029] In a preferred embodiment of the present application, the first lug 4 may include a first pad 41, a first connecting plate 42 and a first rib plate 43. Figure 3As shown, the first pad 41 is welded to the side wall of the large pressure vessel, the first connecting plate 42 is placed horizontally and welded to the first pad 41, the first rib plate 43 is placed vertically and welded to the lower end of the first connecting plate 42 and the first rib plate 43, and the first bracket 1 is detachably connected to the first connecting plate 42 by bolts and nuts. In other embodiments, other detachable methods other than bolt and nut connection can also be used to connect the first bracket 1 to the first connecting plate 42. The detachable method enables the first support ear 4 to be assembled flexibly, wherein the first support ear 4 can be assembled on site, that is, welded to the large pressure vessel on site and connected to the first bracket 1, or it can be welded to the large pressure vessel immediately after the large pressure vessel is manufactured, and connected to the first bracket 1 after being transported to the designated location.

[0030] In a preferred embodiment of the present application, the second lug 5 may include a second pad 51, a first trapezoidal connecting block 52 and a second trapezoidal connecting block 53. Figure 6 and Figure 7 As shown, the second pad 51 is welded to the side wall of the small pressure vessel; one end of the first trapezoidal connecting block 52 faces the second pad 51, and the other end of the first trapezoidal connecting block 52 has a first inclined plane; one end of the second trapezoidal connecting block 53 is welded to the first bracket 1 or the second bracket 2, and the other end of the second trapezoidal connecting block 53 has a second inclined plane matching the first inclined plane; the first inclined plane and the second inclined plane are in contact with each other and can move and fix relatively, so that there is a gap of 2mm between the first trapezoidal connecting block 52 and the second pad 51 after fixation. The 2mm gap between the first trapezoidal connecting block 52 and the second pad 51 allows the small pressure vessel to move relative to each other within a certain range, which helps to release the load and avoid stress concentration. In a specific embodiment, the first inclined plane and the second inclined plane can be fixed by welding after adjusting the relative position, and welding can ensure that the first trapezoidal connecting block 52 and the second trapezoidal connecting block 53 are firmly fixed together. In an alternative embodiment, the first inclined plane and the second inclined plane can be fixed by a stopper after the relative position is adjusted, and the stopper helps to quickly adjust the relative position between the two and facilitates disassembly. In another alternative embodiment of the present application, the first inclined plane and the second inclined plane can adjust the relative position by a stopper and be fixed by welding.

[0031] In a preferred embodiment of the present application, the third lug 6 may include a third pad 61 and a third connecting plate 62. Figure 4 and Figure 5, the third pad 61 is welded to the side wall of the large pressure vessel and is located below the first pad 41, the third connecting plate 62 is placed vertically and welded to the third pad 61, and the third bracket 3 is detachably connected to the third connecting plate 62 by bolts and nuts. In other embodiments, other detachable methods other than bolt and nut connection can also be used to connect the third bracket 3 to the third connecting plate 62. Similar to the first bracket 1, the third bracket 3 can be assembled on site or welded to the large pressure vessel in advance. The detachable connection between the first bracket 1 and the first lug 4 and the third bracket 3 and the third lug 6 makes the entire bracket structure flexible and changeable, and the operator can assemble it as needed.

[0032] In a preferred embodiment of the present application, the first bracket 1 can be made of channel steel, which further reduces the weight of the bracket and saves materials compared to other solid steel materials. Further preferably, the first bracket 1 made of channel steel is fixedly connected (for example, welded) with a second connecting plate 44 at the lower end of the side away from the small pressure vessel, and the second connecting plate 44 is detachably connected to the first connecting plate 42 by bolts and nuts. Such a structure avoids the problem of decreased stability of the channel steel caused by opening a through hole in the channel of the channel steel for passing the bolts.

[0033] In a preferred embodiment of the present application, the second bracket 2 can be made of channel steel to reduce the overall weight of the bracket. Further preferably, the first bracket 1 and the second bracket 2 made of channel steel are further provided with a second rib plate 54 at the position where the second trapezoidal connecting block 53 is welded. Figure 6 As shown, the second rib plate 54 ensures that the two ends of the slot of the channel steel will not be deformed due to the interaction force between the first trapezoidal connecting block 52 and the second trapezoidal connecting block 53.

[0034] In a preferred embodiment of the present application, a first cushion block 45 is further provided between the second connecting plate 44 and the first connecting plate 42. Figure 3 As shown, the first spacer 45 can be used in conjunction with a bolt and nut connection to make the connection more secure and reduce the risk of material damage.

[0035] In a preferred embodiment of the present application, the third bracket 3 is made of angle steel, thereby further reducing the overall weight of the bracket. Figure 5 As shown, a second cushion block 63 is further provided between the third bracket 3 and the third connecting plate 62 for reinforcement and protection.

[0036] In a preferred embodiment of the present application, Figure 8 As shown, the first pad 41 and the third pad 61 are evenly opened with holes, and the first pad 41 and the third pad 61 can be welded to the large pressure vessel by plug welding. Plug welding has a fast construction speed and high connection strength. After plug welding, the area near the hole can be ground flat to avoid stress concentration.
