Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a sliding support device and a pressure vessel. Background Technology

[0002] During operation, especially hot water spherical tanks in air-based energy storage systems, spherical tanks undergo frequent temperature changes (such as cycling from room temperature to 200℃~240℃). Existing spherical tanks are supported on a foundation platform by multiple support columns welded to the tank body, with the support columns anchored to the foundation platform using anchor bolts. However, the existing support columns cannot accommodate the thermal expansion and deformation of the spherical tank, resulting in significant localized stress at the base of the support columns and on the tank shell. Long-term accumulation of this stress can easily lead to fatigue cracks, reducing structural safety and service life. Utility Model Content

[0003] One objective of this invention is to overcome the shortcomings of existing technologies and provide a sliding support device. To solve the aforementioned technical problems, this invention adopts the following technical solution:

[0004] A sliding support device, comprising:

[0005] The main support body has a top end for connecting to the tank of the pressure vessel, and a bottom support plate at the bottom end.

[0006] The sliding assembly includes a mounting support, a rolling structure, and a connector. The mounting support is used to fix the pressure vessel to the mounting base surface. The rolling structure is disposed on the mounting support and is used to roll in contact with the supporting base plate. The connector passes through the mounting support, and its two ends are used to connect the pressure vessel's mounting base and the supporting base plate, respectively.

[0007] The support base plate is provided with an elongated hole for the top of the connector to pass through. The elongated hole extends along the horizontal radial direction of the tank, allowing the support base plate to slide back and forth relative to the mounting bracket in the horizontal radial direction of the tank.

[0008] In one embodiment, the mounting support is a box structure with an open top, and a mounting cavity is formed inside the mounting support, in which the rolling structure is housed.

[0009] In one embodiment, the sliding support device further includes a lubrication structure disposed between the rolling structure and the support base plate to reduce the coefficient of friction between the rolling structure and the support base plate.

[0010] In one embodiment, the mounting cavity is a cavity structure with a closed bottom, and the lubrication structure is lubricating grease, which fills the mounting cavity.

[0011] In one embodiment, the mounting bracket is further provided with a connecting cavity, which is located on one side of the mounting cavity. The connecting cavity and the mounting cavity are independent of each other. A connecting through hole is provided on the bottom wall of the connecting cavity, and the connector passes through the connecting through hole.

[0012] In one embodiment, the rolling structure includes a shaft core and a cylindrical body rotatably disposed outside the shaft core, with a rotating bearing provided between the shaft core and the cylindrical body;

[0013] The axial direction of the shaft is perpendicular to the length extension direction of the elongated hole. The two ends of the shaft are respectively connected to the opposite side walls of the mounting support.

[0015] The sliding assembly has two connectors, the top ends of which are respectively inserted into two elongated holes, and the bottom ends of which are respectively connected to the mounting base of the pressure vessel.

[0016] In one embodiment, the connector includes a connecting bolt and a connecting nut. The connecting bolt passes through the mounting support, and the bottom end of the connecting bolt is fixedly connected to the mounting base of the pressure vessel. The top end of the connecting bolt passes through an elongated hole and protrudes from the support base plate. The connecting nut is threadedly connected to the end of the connecting bolt that protrudes from the support base plate.

[0017] In one embodiment, the connecting nut is a double nut structure.

[0018] Another objective of this invention is to provide a pressure vessel, comprising a tank body and a sliding support device as described in any of the above embodiments, wherein the top end of the support body is connected to the outer wall of the tank body.

[0037] See Figure 1 This utility model provides a pressure vessel 10, including a tank body 11 and a sliding support device 12 disposed at the bottom of the tank body 11. The tank body 11 can be a spherical tank, or it can be a cylindrical tank. Multiple sliding support devices 12 can be provided, and these devices can be evenly connected to the bottom of the tank body 11 along its circumference to stably support the tank body 11.

[0038] The following will describe in detail the specific embodiments of the sliding support device 12 of this utility model with reference to the accompanying drawings.

[0039] Please see Figure 2 and Figure 3 As shown, the sliding support device 12 of this embodiment includes a support body 100 and a sliding assembly 200. The top end of the support body 100 is used to connect to the tank body 11 of the pressure vessel 10, and the bottom end of the support body 100 is provided with a support base plate 110. The sliding assembly 200 includes a mounting bracket 210, a rolling structure 220, and a connecting member 230. The mounting bracket 210 is used to be fixedly installed on the mounting base surface of the pressure vessel 10. The rolling structure 220 is disposed on the mounting bracket 210 and is used to roll in contact with the support base plate 110. The connecting member 230 passes through the mounting bracket 210, and its two ends are used to connect the mounting base of the pressure vessel 10 and the support base plate 110, respectively.

[0040] The support base plate 110 is provided with an elongated hole 111, which is used to pass through the top end of the connector 230. The elongated hole 111 extends along the horizontal radial direction of the tank body 11, so that the support base plate 110 can slide back and forth relative to the mounting support 210 in the horizontal radial direction of the tank body 11.

[0041] The sliding support device 12 of this utility model has a top end of the support body 100 fixedly connected to the tank body 11, and the bottom end of the support body 100 cooperates with the sliding component 200 through the support base plate 110, which enables the support body 100 to slide along the horizontal radial direction of the tank body 11. When the tank body 11 expands or contracts due to temperature changes, the support body 100 can adapt to the displacement within a certain range, thereby effectively avoiding stress concentration between the support body and the tank body, reducing the risk of fatigue cracks, and thus improving the safety and reliability of the pressure vessel and enhancing its long-term stability.

[0042] See Figure 1 For ease of description, it is hereby defined that the direction of gravity of tank 11 is the up and down direction, and the horizontal radial direction of tank 11 is the direction of the horizontal plane passing through the center of tank 11.

[0043] like Figure 2 As shown, the support body 100 extends vertically, with its top end connected to the tank 11 and its bottom end slidably connected to the mounting base via a sliding assembly 200. The support body 100 can be a column structure with a circular or square cross-section. The support body 100 can be made of metal, for example, it can be made of steel of the same or similar material as the tank 11.

[0044] For example, the top of the support body 100 may be welded and fixed to the outer wall of the tank 11 to ensure a reliable connection between the two. The support base plate 110 may be welded and fixed to the bottom of the support body 100 to ensure a reliable connection between the two.

[0045] like Figure 3 As shown, the support base plate 110 is provided with an elongated hole 111 for the connector 230 to pass through. The length of the elongated hole 111 extends along the horizontal radial direction of the tank body 11, so that the connector 230 can move in the elongated hole 111 along the horizontal radial direction of the tank body 11, thereby limiting the sliding direction of the support body 100 and enabling the support body 100 to adapt to the displacement caused by the thermal expansion and contraction of the tank body 11 along the horizontal radial direction of the tank body 11.

[0046] Optionally, two elongated holes 111 on the support base plate 110 can be provided, with the two elongated holes 111 symmetrically arranged on both sides of the support body 100. By providing two elongated holes 111, two connectors 230 can be passed through them respectively, which can enhance the stability of the support body 100 in the horizontal radial direction and improve the reliability of the connection between the support body 100 and the mounting bracket 210, thereby improving the stability of the support body 100 and the support of the tank 11.

[0047] SeeFigure 2 In this invention, the sliding component 200 is mainly used to enable the support body 100 to adapt to the thermal expansion and contraction of the tank 11 and move in the horizontal radial direction. For example, the sliding component 200 includes a mounting bracket 210, a rolling structure 220, and a connector 230.

[0048] The mounting bracket 210 is used to fix the pressure vessel 10 to the mounting base surface. Optionally, the mounting base of the pressure vessel 10 can be a reinforced concrete boss. The mounting bracket 210 can be made of metal. The mounting bracket 210 can be fixed to the reinforced concrete boss using connectors 230, anchor bolts, or welding. The outer surface of the mounting bracket 210 can be coated with epoxy zinc-rich primer and polyurethane topcoat to improve its weather resistance.

[0049] like Figure 3 and Figure 4 As shown, in one embodiment, the mounting support 210 is a box structure with an open top, and a mounting cavity 211 is formed inside the mounting support 210, in which the rolling structure 220 is housed.

[0050] For example, the mounting bracket 210 can be a square box structure. The mounting bracket 210 may include a bottom wall and four circumferential side walls, which together can form a square box with an open top. The mounting bracket 210 may have two partitions 21 arranged in parallel at intervals, and the space between the two partitions 21 can form a mounting cavity 211 for mounting the rolling structure 220.

[0051] Optionally, the mounting cavity 211 is a cavity structure closed at the bottom. For example... Figure 4 As shown, the bottom end of each partition 21 is welded and fixed to the bottom wall of the mounting support 210, and the two ends of each partition 21 are welded and fixed to the opposite side walls of the mounting support 210. Thus, the bottom wall of the mounting support 210 between the two partitions 21, the side wall portion of the mounting support 210 between the two partitions 21, and the two partitions 21 can be enclosed to form a mounting cavity 211 with a closed bottom.

[0052] See Figure 4 In one embodiment, the mounting support 210 is further provided with a connecting cavity 212, which is located on one side of the mounting cavity 211 and is independent of the mounting cavity 211. In this embodiment, by providing a connecting cavity 212 that is independent of the mounting cavity 211, the connecting cavity 212 can be used to arrange the connector 230 to avoid damaging the sealing of the mounting cavity 211.

[0053] For example, such as Figure 4As shown, two spaced connecting plates 22 may be provided between the partition 21 and the side wall of the opposite mounting support 210, and the space between the two connecting plates may form a connecting cavity 212. Optionally, two connecting cavities 212 may be provided to accommodate two connecting members 230 respectively.

[0054] Understandable, such as Figure 4 As shown, a mounting cavity 211 for mounting the rolling structure 220 can also be formed between each connecting plate 222 and the side wall of the opposite mounting support 210. By configuring the mounting support 210 in this way, the space outside the connecting member 230 in the mounting support 210 can be fully utilized to mount the rolling structure 220, thereby increasing the rolling contact area between the rolling structure 220 and the supporting base plate 110 and improving the sliding flexibility of the supporting base plate 110.

[0055] See Figure 3 and Figure 4 The rolling structure 220 is housed within the mounting cavity 211. Optionally, the rolling structure 220 includes a shaft core 221 and a cylindrical body 222 rotatably disposed outside the shaft core 221, with a rotating bearing 223 provided between the shaft core 221 and the cylindrical body 222.

[0056] The axial direction of the shaft core 221 is perpendicular to the length extension direction of the elongated hole 111, and the two ends of the shaft core 221 are respectively connected to the opposite side walls of the mounting support 210. (See also...) Figure 4 When the mounting cavity 211 is formed by the bottom wall of the mounting support 210 located between the two partitions 21, the side wall portion of the mounting support 210 located between the two partitions 21, and the two partitions 21, the two ends of the shaft core 221 are respectively fixed to the side wall portion of the mounting support 210 located between the two partitions 21. When the mounting cavity 211 is formed by the connecting plate 22, a portion of the wall surface of the partitions 21, two adjacent side wall portions of the mounting support 210, and the corresponding bottom wall portion of the mounting support 210, the two ends of the shaft core 221 are respectively fixed to the connecting plate 22 and the side wall of the mounting support 210 opposite to the connecting plate 22.

[0057] Optionally, the two ends of the shaft core 221 can be welded and fixed to the corresponding side walls respectively to ensure the sealing of the connection between the shaft core 221 and the mounting support 210, and to ensure the sealing of the mounting cavity 211.

[0058] like Figure 4 As shown, the cylinder 222 is rotatably connected to the shaft core 221 via a rotating bearing 223. The outer circumferential surface of the cylinder 222 is not lower than the top surface of the mounting support 210 so as to be able to roll contact with the support base plate 110.

[0059] In this embodiment, the cylinder 222 is used to roll contact with the support base plate 110. A rotating bearing 223 is provided between the cylinder 222 and the shaft core 221, which can improve the smoothness of the rotation of the cylinder 222 relative to the shaft core 221, thereby ensuring the smoothness of the sliding of the support base plate 110 relative to the mounting support 210, so as to ensure that the support body 100 can adaptively move in the horizontal radial direction when the tank 11 expands and contracts with heat.

[0060] It should be noted that, in the embodiments of this utility model, the rolling structure 220 includes a shaft core 221, a cylinder 222, and a rotating bearing 223. However, this utility model is not limited to this; in other embodiments, the rolling structure 220 may also be a roller or a ball bearing, etc., and can be specifically set according to actual needs.

[0061] See Figure 4 In one embodiment, the sliding support device 12 further includes a lubrication structure 240 disposed between the rolling structure 220 and the support base plate 110 to reduce the coefficient of friction between the rolling structure 220 and the support base plate 110. Optionally, the lubrication structure 240 can be lubricating grease, which is filled in the mounting cavity 211. Since the rolling structure 220 is housed in the mounting cavity 211, by filling the mounting cavity 211 with lubricating grease, the lubricating grease can not only effectively reduce the coefficient of friction between the cylinder 222 and the support base plate 110, enabling the support body 100 to more sensitively adapt to the temperature changes of the tank 11 for displacement, but also effectively prevent the rust and corrosion of the components of the rolling structure 220, extending the service life of the rolling structure 220.

[0062] It is understood that in other embodiments, the lubrication structure 240 may also be graphite grease or a solid lubricant, depending on actual needs. For example, graphite grease or solid lubricants are more suitable for use in environments with long-term high temperatures.

[0063] See Figure 4 The mounting bracket 210 has a connecting cavity 212. For example, a connecting through hole 213 is formed on the bottom wall of the connecting cavity 212, and the connector 230 passes through the connecting through hole 213. It can be understood that the connecting through hole 213 can be a square hole or a circular hole, etc. The size of the connecting through hole 213 can be slightly larger than the radial dimension of the connector 230 to facilitate the smooth passage of the connector 230.

[0064] like Figure 4As shown, the connector 230 passes through the connecting through hole 213 of the mounting bracket 210 and is connected to the mounting base at the bottom of the mounting bracket 210 and the support base plate 110 at the top of the mounting bracket 210, respectively. In this embodiment, the connector 230 not only connects and fixes the mounting bracket 210 to the mounting base, but also limits and fixes the support base plate 110 to the top of the mounting bracket 210 in the vertical direction. At the same time, since the top end of the connector 230 passes through the elongated hole 111 of the support base plate 110, the support base plate 110 can slide relative to the mounting bracket 210 in the horizontal radial direction.

[0065] Optionally, the mounting support 210 may be provided with two connectors 230, the top ends of which pass through two elongated holes 111 respectively. The bottom ends of the two connectors 230 are respectively connected to the mounting base of the pressure vessel 10.

[0066] like Figure 3 As shown, in one embodiment, the connector 230 includes a connecting bolt 231 and a connecting nut 232, with the connecting bolt 231 passing through the mounting bracket 210. For example, the connecting bolt 231 passes through the connecting through hole 213 of the mounting bracket 210.

[0067] The connecting bolt 231 can be made of metal. The bottom end of the connecting bolt 231 can be welded and fixed to the reinforcing steel bar inside the reinforced concrete boss. Optionally, the connecting bolt 231 can be an anchor bolt pre-embedded in the reinforced concrete boss.

[0068] The top end of the connecting bolt 231 passes through the elongated hole 111 and protrudes from the support base plate 110. The connecting nut 232 is threadedly connected to the end of the connecting bolt 231 that protrudes from the support base plate 110.

[0069] Optionally, the connecting nut 232 is a double nut structure. This ensures the installation reliability between the support base plate 110 and the mounting bracket 210, and effectively prevents the support base plate 110 from detaching from the mounting bracket 210 in the vertical direction.

[0070] Optionally, the connector 230 may further include a washer 233, which is sleeved around the connecting bolt 231 and positioned between the connecting nut 232 and the support base plate 110. The washer 233 may be made of a wear-resistant material with a low coefficient of friction, such as stainless steel, copper-based alloy, or polytetrafluoroethylene (PTFE). By providing the washer 233 between the connecting nut 232 and the support base plate 110, the coefficient of friction between them can be reduced, thereby decreasing the sliding resistance of the support base plate 110.

[0071] In the manufacturing process of this utility model embodiment, the sliding support device 12 can be first assembled from steel plates by welding to form a mounting support 210 having multiple mounting cavities 211 and two connecting cavities 212. It is necessary to ensure the bottom end sealing of the mounting cavities 211. It is understood that during use, the mounting cavities 211 of the sliding support device 12 can be filled with lubricating grease.

[0072] Next, the rolling structure 220 is installed into the mounting cavity 211 of the mounting support 210. Specifically, the two ends of the shaft core 221 are welded to the two side walls of the mounting cavity 211 respectively, and the coaxiality of each shaft core 221 must be ensured.

[0073] In addition, two connecting through holes 213 can be opened on the bottom wall of the mounting bracket 210 corresponding to the positions of the two connecting cavities 212.

[0074] During on-site installation of the sliding support device 12 according to this embodiment of the invention, the mounting bracket 210 is first initially fixed to the reinforced concrete boss using connecting bolts 231, and the levelness of the mounting bracket 210 is adjusted. The mounting bracket 210 is then welded and fixed to the reinforcing mesh of the reinforced concrete boss, thereby enhancing the lateral force resistance of the sliding support device 12.

[0075] Then, align the elongated hole 111 of the support base plate 110 with the connecting bolt 231 and place it on the mounting bracket 210 so that the support base plate 110 contacts the surface of each cylinder 222, ensuring that the support base plate 110 can slide freely in the horizontal direction.

[0076] Subsequently, the double nuts at the top of the connecting bolts 231 are tightened, and an appropriate gap is maintained between the double nuts and the support base plate 110 to prevent the double nuts from being too tight and restricting the sliding of the support base plate 110.

[0077] Finally, the sliding support device 12 can be debugged and accepted: for example, the support base plate 110 can be manually pushed to check whether its sliding is smooth. Also, thermal expansion conditions can be simulated to measure whether the actual sliding amount of the support base plate 110 meets the design requirements.

[0078] See Figure 5 As shown, the sliding support device 12 of this utility model embodiment operates at room temperature, for example, as can be seen from... Figure 5 The sliding support device 12 is indicated by the middle arrow C. At this time, the center of the support base plate 110 can coincide vertically with the center of the mounting bracket 21. The connector 230 can be located in the middle of the elongated hole 111, and there is no relative movement between the support base plate 110 and the rolling structure 220.

[0079] When the tank 11 heats up and expands, it tends to expand in the horizontal radial direction. At this time, under the rolling contact action of the rolling structure 220 and the guiding action of the connecting bolts 231 and the elongated hole 111, the supporting base plate 110 can slide in the horizontal radial direction to compensate for the displacement of the heated and expanding tank 11, thereby avoiding stress concentration between the supporting body 100 and the tank 11. For example, see reference... Figure 5 The position of the sliding support device 12 indicated by the middle arrow D.

[0080] When the tank 11 cools down and shrinks, the tank 11 tends to shrink in the horizontal radial direction. At this time, the support base plate 110 can slide in the opposite direction in the horizontal radial direction to compensate for the displacement of the tank 11 as it cools down and shrinks, thereby avoiding the stress concentration problem between the support body 100 and the tank 11.

[0081] The sliding support device of this utility model includes a support body and a sliding assembly. The bottom end of the support body is provided with a support base plate, and the support base plate has an elongated hole. The sliding assembly includes a mounting bracket, a rolling structure, and a connecting component. Since the top end of the support body is fixedly connected to the tank body, and the bottom end of the support body cooperates with the sliding assembly through the support base plate, the support body can slide along the horizontal radial direction of the tank body. When the tank body expands or contracts due to temperature changes, the support body can adapt and displace within a certain range, thereby effectively avoiding stress concentration between the support body and the tank body, reducing the risk of fatigue cracks, and thus improving the safety and reliability of the pressure vessel and enhancing its long-term stability.

[0082] The sliding support device of this utility model fills the space between the rolling structure and the mounting bracket with lubricating grease. Combined with the rotating bearing in the rolling structure, the coefficient of sliding friction can be reduced to below 0.05, improving the smoothness of sliding of the support base plate. The lubricating grease not only significantly reduces the risk of jamming in the rolling structure, but also effectively inhibits its corrosion and abrasion, extending the service life of the rolling structure, and significantly improving the durability of the sliding support device under high-temperature (e.g., 200℃~240℃) cyclic conditions.

[0083] The sliding support device of this utility model embodiment allows for the prefabrication and assembly of the mounting support and rolling structure, thereby enabling modular manufacturing and installation of the sliding support device. On-site installation only requires the mounting support, support body, and anchor bolts, facilitating construction and ensuring the connection rigidity of the sliding support device while enabling rapid installation and operation maintenance.

[0084] The sliding support device of this utility model embodiment can realize the radial free sliding of the spherical tank under temperature alternation conditions, and completely solves the fatigue damage problem caused by thermal stress concentration in traditional fixed support columns.

[0085] The sliding support device of this utility model solves the stress concentration problem caused by thermal expansion and contraction of spherical tanks under alternating temperature conditions. It is particularly suitable for hot water spherical tanks in air energy storage projects that frequently undergo high-temperature cycles (such as 200℃~240℃). This sliding support device allows the support body to adapt to radial displacement fluctuations, thereby effectively eliminating thermal stress concentration and significantly improving the safety and reliability of the spherical tank body and the long-term stability of the support body under thermal cycling conditions.

[0086] The sliding support device of this invention is suitable for high-temperature spherical tanks in air energy storage projects, and can also be extended to spherical tank support systems in fields such as chemical engineering and energy where there are periodic thermal cycles. Compared with traditional fixed support columns, this invention solves the risk of fatigue cracking caused by thermal stress accumulation through a dynamic sliding mechanism, providing a reliable support solution for industrial equipment that has been subjected to alternating temperatures above 200°C for a long time.

[0087] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0088] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
