Description

Technical Field

[0001] The invention relates to the field of membrane storage tanks, in particular to a membrane storage tank pump tower base device and an installation method thereof. Background Art

[0002] Cryogenic membrane storage tank is a large-scale equipment used to store cryogenic media such as liquefied natural gas. Its structure includes concrete outer tank, inner tank and pump tower. The pump tower base is the key structure connecting the pump tower and the concrete foundation. Its design directly affects the safety, stability and transmission efficiency of liquefied natural gas transmission.

[0003] At present, the pump tower base in the prior art is mainly suitable for membrane storage tanks with a centrally symmetrical arrangement at the bottom. This base adopts an integral support structure and is bulky. When applied to membrane storage tanks, it will seriously interfere with the continuity of the corrugated plate, resulting in corrugation fractures. Secondly, as a key shielding component of the storage tank, the continuity of the corrugated plate is crucial to the sealing effect and thermal insulation performance. The fracture caused by the traditional base passing through the corrugated layer will form a low-temperature "thermal bridge", resulting in leakage of low-temperature media, which not only reduces the insulation efficiency, but may also cause cracks in the concrete foundation. In addition, the existing base structure is difficult to effectively integrate with the rectangular corrugated system, which increases the difficulty and cost of installation.

[0004] Therefore, it is urgent to propose a membrane storage tank pump tower base device and an installation method thereof to solve the above problems. Summary of the invention

[0010] Furthermore, resin mortar is provided between the insulation box, the steel plate and the concrete foundation.

[0011] Furthermore, it also includes glass wool; there is a first filling space between the main layer wing panel and the secondary layer wing panel; there is a second filling space between the secondary layer wing panel, the support seat, the insulation box and the steel plate; the glass wool is filled into the first filling space, the second filling space and the inside of the support seat.

[0012] Furthermore, a guiding mechanism is provided on the main base.

[0013] Furthermore, the corrugated plate includes longitudinal corrugations and transverse corrugations; the longitudinal corrugations and transverse corrugations are perpendicular and cross-shaped to form a grid structure with multiple grids; the number of the wing plates and the support seats is correspondingly arranged to four, and the four wing plates are evenly distributed in a rectangular shape; the four wing plates are respectively located in four different areas of the grid structure; the four support seats respectively pass through the corresponding wing plates.

[0014] In addition, the present invention also provides a method for installing a membrane storage tank pump tower base device, which is used to install the membrane storage tank pump tower base device as described above, and specifically includes the following: Embed steel plates in concrete foundation; Installing a plurality of support seats on the steel plate, connecting and passing through the wing plate; A shielding layer is formed by connecting the corrugated plate and the wing plate; A supporting platform is installed on the supporting seat so that the shielding layer is located below the supporting platform, and a main base is installed above the supporting platform.

[0015] Furthermore, the shielding layer is formed by connecting the corrugated plate and the wing plate, specifically comprising: First, fill the inside of each support seat with glass wool, then install an insulating box around the support seat, and fill the second filling space between the insulating box and the support seat with glass wool; then, install a secondary corrugated plate on the insulating box, and the secondary corrugated plate is connected to the secondary wing plate to form a secondary shielding layer; then, arrange a main layer plywood on the secondary corrugated plate, and fill the first filling space between the main layer wing plate and the secondary layer wing plate with glass wool; then, install the main layer corrugated plate on the main layer plywood, and the main layer corrugated plate is connected to the main layer wing plate to form a main shielding layer.

DETAILED DESCRIPTION

[0020] A membrane storage tank pump tower base device and its installation method of the present invention will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0021] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0022] like Figure 1 As shown, an embodiment of the present invention proposes a membrane storage tank pump tower base device, including a main base 1, a support platform 2, a plurality of support seats 3, a corrugated plate 4 and a wing plate 5.

[0023] Specifically, the main base 1 and the support base 3 are respectively installed above and below the support platform 2; the wing plate 5 is connected to the corrugated plate 4 to form a shielding layer, and the shielding layer is located below the support platform 2; the support base 3 passes through the wing plate 5, one end is connected to the support platform 2, and the other end extends to the concrete foundation 8 and is connected to the steel plate 9.

[0024] The support seat 3 and the wing plate 5 can be integrally formed. The wing plate 5 is located between adjacent corrugated plates 4, and there is a space between multiple support seats 3, and part of the corrugated plates 4 exists in the space, and part of the corrugated plates 4 is located between adjacent wing plates 5. Figure 1 shown.

[0025] In one embodiment, the main base 1 is a cylindrical structure, and can also be set to a rectangular column structure as needed. The specific size and material of the main base 1 can be set according to actual needs, which can effectively bear the load of the pump tower and improve the structural stability. The support platform 2 can be a disc-shaped structure or a rectangular structure. The diameter or side length of the support platform 2 is larger than the main base 1, and a plurality of reserved connection holes are evenly arranged around it for connection with the support seat 3. The top surface of the support platform 2 is fixedly connected to the bottom surface of the main base 1 by welding, which can enhance the stability and bearing capacity of the overall structure. Compared with the bulky structure of the traditional pump tower base, the device is designed with multiple support seats 3 distributed near the corrugations of the corrugated plate 4, so that the corrugated plate 4 can be arranged continuously, thereby solving the problem that the excessive volume of the traditional pump tower base affects the continuity of the corrugations and improves the sealing performance of the storage tank.

[0026] In this embodiment, combined with Figure 2 and Figure 3 As shown, the corrugated plate 4 includes a main layer corrugated plate 41 and a secondary layer corrugated plate 42 arranged from top to bottom. Specifically, the wing plate 5 includes a main layer wing plate 51 and a secondary layer wing plate 52 arranged from top to bottom; the main layer corrugated plate 41 is connected with the main layer wing plate 51 to form a main shielding layer, and the secondary layer corrugated plate 42 is connected with the secondary layer wing plate 52 to form a secondary shielding layer; the support seat 3 passes through the main layer wing plate 51 and the secondary layer wing plate 52 in sequence, and the support seat and the wing plate are fixedly connected by welding.

[0027] Furthermore, a main layer of plywood 6 is provided between the main layer of corrugated plate 41 and the secondary layer of corrugated plate 42. Preferably, the main layer of plywood 6 can be made of a specially treated low temperature resistant material, and filled in the space between the main layer of corrugated plate 41 and the secondary layer of corrugated plate 42 to form a continuous heat insulation layer. The main layer of plywood 6 not only provides additional heat insulation protection, but also enhances the rigidity and stability of the corrugated plate 4 structure, reduces deformation and stress concentration. The material and thickness of the plywood can be accurately calculated and selected according to actual needs, so that it can still have good physical properties and heat insulation effects in extremely low temperature environments, further improving the performance and reliability of the overall shielding structure.

[0028] In a specific example, the main layer corrugated plate 41 is located on the outside, the secondary layer corrugated plate 42 is located on the inside, and the main layer plywood 6 is filled between the two layers of corrugated plates 4. The main layer corrugated plate 41 and the secondary layer corrugated plate 42 are connected with the corresponding wing plate 5 to form a double-layer shielding structure, thereby improving the overall sealing performance and heat insulation effect, and effectively reducing low-temperature leakage and heat conduction.

[0029] In one embodiment, if Figure 4As shown, this embodiment also includes a secondary plywood 71 and polyurethane 72. Specifically, the secondary plywood 71 is arranged on both sides of the polyurethane 72 to form an insulation box 7. The insulation box 7 is arranged around the support seat 3 and is located between the secondary corrugated plate 42 and the steel plate 9 and the concrete foundation 8. The material of the secondary plywood 71 can be selected according to actual needs, for example, it is made of high-strength and low-temperature resistant material. The insulation box 7 formed by the secondary plywood 71 and the polyurethane 72 is arranged around the support seat 3 to play a role in heat insulation protection. The insulation box 7 is located between the secondary corrugated plate 42 and the steel plate 9 and the concrete foundation 8 (from Figure 1 As can be seen in the figure, the steel plate 9 and the concrete foundation 8 form a whole, and the insulation box 7 is located between the whole and the secondary corrugated plate 42, effectively blocking the heat conduction path and reducing the "thermal bridge" effect. The setting of the insulation box 7 can further enhance the thermal insulation performance of the overall structure, especially in the transition area between the support seat 3 and the secondary corrugated plate 42, providing more comprehensive thermal insulation protection, significantly reducing the heat loss of the cryogenic storage tank, thereby improving energy efficiency and operational safety.

[0030] Preferably, a resin cement 11 is provided between the insulating box 7 and the steel plate 9 and the concrete foundation 8. The resin cement 11 is filled in the gap between the insulating box 7 and the steel plate 9 and the concrete foundation 8 (from Figure 1 It can be seen that the steel plate 9 and the concrete foundation 8 form a whole, that is, the resin cement 11 is filled in the gap between the insulation box 7 and the whole), which plays the role of fixing the insulation box and transferring the load.

[0031] Preferably, continue to refer to Figure 1 As shown, this embodiment also includes glass wool 10. Specifically, there is a first filling space between the main wing plate 51 and the secondary wing plate 52; there is a second filling space between the secondary wing plate 52, the support seat 3, the insulation box 7 and the steel plate 9, and the glass wool 10 is filled into the first filling space, the second filling space and the inside of the support seat 3. It can effectively avoid the cold leakage phenomenon between the components, improve the overall thermal insulation effect, and reduce the conduction of low temperature to the concrete foundation 8. The filling of glass wool 10 not only improves the thermal insulation performance, but also enhances the vibration resistance of the overall structure, reduces the structural stress caused by temperature changes and external vibrations, and thus extends the service life of the device.

[0032] In this embodiment, a guide mechanism 12 is provided on the main base 1 for guiding the vertical displacement of the pump tower and restricting the lateral displacement of the pump tower.

[0033] In a specific example, combining Figure 5As shown, the corrugated plate 4 includes longitudinal corrugations 43 and transverse corrugations 44. Specifically, the longitudinal corrugations 43 and transverse corrugations 44 are perpendicular and cross-shaped to form a grid structure with multiple grids; the number of the wing plates 5 and the support seat 3 is correspondingly arranged to four, and the four wing plates 5 (each wing plate 5 includes a main layer wing plate 51 and a secondary layer wing plate 52) are evenly distributed in a rectangular shape; the four wing plates 5 are respectively located in non-corrugated positions in four different areas of the grid structure; the four support seats 3 respectively pass through the corresponding wing plates 5 to avoid the corrugations and do not interfere with the continuity of the corrugations. In this embodiment, the four wing plates 5 are evenly distributed in a rectangular shape and are located in four different areas of the grid structure, so that the structure has symmetry and the load is evenly distributed.

[0034] In one embodiment, the support seat 3 includes a connecting portion and an extending portion arranged from top to bottom. Specifically, the connecting portion is connected to the supporting platform 2, one end of the extending portion is connected to the connecting portion, and the other end passes through the wing plate 5 and is connected to the steel plate 9. The extending portion passes through the wing plate 5 and is firmly connected to the wing plate 5 and the steel plate 9 by welding to form a complete load transfer path.

[0035] In addition, if Figure 6 As shown, this embodiment also provides a method for installing a membrane storage tank pump tower base device, which is used to install the membrane storage tank pump tower base device as described above, and specifically includes the following steps: S1, embedding a steel plate 9 in a concrete foundation 8; S2, installing a plurality of support seats 3 on the steel plate 9, connecting and passing through the wing plate 5; S3, forming a shielding layer by connecting the corrugated plate 4 and the wing plate 5; S4, installing the support platform 2 on the support seat 3 so that the shielding layer is located below the support platform 2, and installing the main base 1 above the support platform 2.

[0036] In this embodiment, before pouring the concrete foundation 8, the steel plate 9 is accurately positioned and fixed according to the design requirements, so that its position corresponds precisely to the node position of the subsequently installed corrugated plate 4. After the concrete is poured and reaches the design strength, a plurality of support seats 3 are evenly distributed and fixedly mounted on the steel plate 9 by welding, wherein the support seats 3 pass through the wing plate 5 (i.e., pass through the primary wing plate 51 and the secondary wing plate 52 in sequence from top to bottom), and are integrally formed with the wing plate 5.

[0037] Secondly, fill the inside of each support seat 3 with glass wool 10, then install an insulating box 7 around the support seat, and fill the second filling space between the insulating box 7 and the support seat 3 with glass wool 10. Then, install the secondary corrugated plate 42 on the insulating box 7, and the secondary corrugated plate 42 is connected to the secondary wing plate 52 (for example, fixed by welding) to form a secondary shielding layer. Subsequently, set the main layer plywood 6 on the secondary corrugated plate 42, and fill the first filling space between the main layer wing plate 51 and the secondary layer wing plate 52 with glass wool 10. Then, install the main layer corrugated plate 41 on the main layer plywood 6, and the main layer corrugated plate 41 is connected to the main layer wing plate 51 (for example, fixed by welding) to form a main shielding layer. Finally, the support platform 2 can be installed on multiple support seats 3, and the main base 1 can be installed above the support platform 2.

[0038] In summary, the membrane storage tank pump tower base device and the installation method thereof proposed by the present invention have the following advantages: By setting multiple support seats at the bottom of the support platform, and setting corrugated plates on the outside of the support seats, connecting the corrugated plates through wing plates to form a shielding layer, and connecting the support seats through the wing plates to the steel plates on the concrete foundation, the problem of the large volume of the traditional pump tower base affecting the continuity of the corrugations is solved. This setting is particularly suitable for membrane storage tanks with rectangular bottom arrangements, which improves the continuity of the corrugated plates, enhances the sealing performance of the storage tanks, reduces the formation of low-temperature "thermal bridges", and extends the service life of the storage tanks.

[0039] In addition, by setting the main layer corrugated plate and the secondary layer corrugated plate to form a primary and secondary double-layer shielding structure, more reliable sealing protection is provided. Filling the gaps between the support seats with insulation materials effectively avoids cold leakage and improves the overall thermal insulation performance. Multiple support seats are evenly distributed and respectively arranged in four different areas of the grid structure formed by the corrugated plate as a whole, so that the corrugated plate can be arranged continuously without interfering with the original arrangement of the corrugated plate, while forming a stable support structure, reducing the difficulty of installation and manufacturing cost.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
