Description

Technical Field

[0001] This utility model relates to the field of chemical storage tanks, and in particular to a multi-pressure-resistant reinforced structure for a high-safety chemical storage tank. Background Technology

[0002] Chemical storage tanks are specialized equipment used to store chemical raw materials, intermediates, and finished products. They can be categorized by material into metal tanks (such as carbon steel and stainless steel tanks) and non-metallic tanks (such as fiberglass and plastic tanks); by structure into domed tanks, floating roof tanks, and spherical tanks; by application into raw material tanks, finished product tanks, and transfer tanks; and by usage environment into above-ground tanks, underground tanks, and containerized tanks. Chemical storage tanks typically possess corrosion resistance, high strength, and a long service life to ensure the safe storage of various chemical substances, such as acids, alkalis, alcohols, gases, and liquids.

[0003] In existing technologies, composite material storage tanks such as steel-lined plastic and steel-lined fiberglass are used. Taking steel-lined plastic storage tanks as an example, the steel body provides structural strength and rigidity, bearing most of the pressure, while the inner plastic lining, such as polyethylene or polytetrafluoroethylene, has good corrosion resistance and a certain degree of flexibility, which can alleviate pressure shocks, prevent the tank body from being corroded, and extend its service life.

[0004] However, current chemical storage tanks still have significant shortcomings in terms of pressure resistance. Most existing tanks rely solely on their material composition for pressure resistance, lacking specialized pressure-strengthening structural designs. In actual use, chemical storage tanks often face multiple pressures, such as pressure from the stored medium inside the tank wall, external environmental forces, and static pressure generated by the weight of the medium. Under the combined influence of these complex pressures, the lack of effective pressure-strengthening measures makes the tank body prone to deformation and even damage. This not only affects the normal use of the chemical storage tank, leading to safety hazards such as leakage of the stored medium, but also poses a serious threat to the surrounding environment and personnel safety, greatly reducing the safety and reliability of chemical storage tank use. Utility Model Content

[0005] The main purpose of this invention is to provide a multi-pressure-resistant reinforced structure for a high-safety chemical storage tank, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-pressure-resistant reinforcement structure for a high-safety chemical storage tank includes a tank body. The outer wall of the tank body is equipped with a maintenance ladder, and the top surface of the tank body has a filling port. The inner and outer walls of the tank body are respectively provided with a first pressure-resistant reinforcement mechanism, which includes longitudinal stiffeners and annular stiffeners. Several longitudinal stiffeners are fixedly connected to the inner and outer walls of the tank body, and several annular stiffeners are also provided on the inner and outer walls of the tank body and fixedly connected to the longitudinal stiffeners by nuts. The bottom surface of the tank body is provided with a second pressure-resistant reinforcement mechanism, which includes an upper base, a lower base, a rubber seat, and springs. The rubber seat is fixedly connected between the upper and lower bases, and several springs are also fixedly connected between the upper and lower bases and outside the rubber seat.

[0008] As a preferred technical solution of this utility model, the inner and outer walls of the tank are fixedly installed with a number of longitudinal ribs in a ring array, and the side walls of the longitudinal ribs are provided with a number of screw holes in a vertical array.

[0009] As a preferred technical solution of this utility model, a number of annular ribs are arranged in a vertical array on the inner and outer walls of the tank. Notches corresponding to the longitudinal ribs are respectively opened on the outer wall of the annular ribs inside the tank and the inner wall of the annular ribs outside the tank. A through mounting hole is also opened on the inner wall of the notch, and a nut is inserted into the mounting hole and threaded together with the screw hole.

[0010] As a preferred embodiment of this utility model, the nut is inserted into the mounting hole and threadedly connected to the screw hole.

[0011] As a preferred technical solution of this utility model, the upper base is fixedly installed at the bottom of the tank body, and the lower base is located below the upper base. The upper base and the lower base are respectively provided with grooves on opposite walls, and a number of intersecting transverse stiffeners and longitudinal stiffeners are fixedly installed inside the grooves, forming a mesh structure between the number of transverse stiffeners and longitudinal stiffeners.

[0012] As a preferred embodiment of this utility model, a fixing ring is fixedly installed between the opposing walls of the upper base and the lower base, and the upper and lower ends of the rubber seat are fixedly installed inside the fixing ring. Several connecting rods are also fixedly installed between the opposing walls of the upper base and the lower base in a circular array, and the two ends of the rubber seat are respectively fitted and fixedly installed on the outer walls of the upper and lower symmetrical connecting rods.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, the first pressure-resistant strengthening mechanism is provided. The longitudinal ribs and annular ribs in the first pressure-resistant strengthening mechanism are fixed on the inner wall and outer wall of the tank respectively, forming a crisscross support network. The longitudinal ribs are installed in a ring array, and the annular ribs are tightly connected to the longitudinal ribs through nuts. This can effectively disperse the pressure on the tank, enhance the overall rigidity of the tank, and significantly improve the tank's resistance to deformation when subjected to the pressure of the internal storage medium, external environmental forces, and static pressure. This reduces the possibility of tank damage and ensures the structural safety of the storage tank.

[0015] Furthermore, the annular ribs are connected to the bolt holes on the longitudinal ribs through notches and mounting holes, and can be fixed with nuts, which is convenient and quick and helps to improve installation efficiency. At the same time, this structural design also facilitates later maintenance and repair work. When a component is damaged, it can be replaced and repaired more easily, reducing maintenance costs and increasing the service life of the storage tank.

[0016] The second pressure-resistant reinforcement mechanism consists of an upper base, a lower base, a rubber seat, and springs. The rubber seat has good elasticity and cushioning performance, which can absorb the energy generated when the tank is subjected to pressure impact and reduce the impact of vibration on the tank. The springs further enhance the cushioning effect and can restore the tank to its original state after the pressure is removed. At the same time, the mesh structure formed by the transverse and longitudinal stiffeners inside the upper and lower bases increases the strength and stability of the base, allowing the tank to bear its own weight and medium pressure more stably when placed, effectively preventing the tank from tilting or being damaged due to uneven force on the bottom, and further improving the pressure resistance and safety of the storage tank.

[0017] Therefore, the combination of multiple pressure-resistant measures achieved through the first and second pressure-resistant strengthening mechanisms effectively improves the pressure resistance and safety of the storage tank, ensuring the smooth progress of chemical production and reducing safety hazards.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] like Figure 1 - Figure 4 As shown, a multi-pressure-resistant reinforcement structure for a high-safety chemical storage tank includes a tank body 1. A maintenance ladder 2 is provided on the outer wall of the tank body 1, and a filling port 3 is provided on the top surface of the tank body 1. First pressure-resistant reinforcement mechanisms 4 are respectively provided on the inner and outer walls of the tank body 1. The first pressure-resistant reinforcement mechanism 4 includes longitudinal stiffeners 6 and annular stiffeners 8. Several longitudinal stiffeners 6 are fixedly connected to the inner and outer walls of the tank body 1, and several annular stiffeners 8 are also provided on the inner and outer walls of the tank body 1 and fixedly connected to the longitudinal stiffeners 6 by nuts 11. A second pressure-resistant reinforcement mechanism 5 is provided on the bottom surface of the tank body 1. The second pressure-resistant reinforcement mechanism 5 includes an upper base 12, a lower base 13, a rubber seat 18, and springs 20. The rubber seat 18 is fixedly connected between the upper base 12 and the lower base 13, and several springs 20 are also fixedly connected between the upper base 12 and the lower base 13 and outside the rubber seat 18.

[0025] Example 1:

[0026] like Figures 1-3 As shown, several longitudinal stiffeners 6 are fixedly installed on the inner and outer walls of the tank 1 in a ring array, and several screw holes 7 are opened in a vertical array on the side walls of the longitudinal stiffeners 6; several ring stiffeners 8 are fitted on the inner and outer walls of the tank 1 in a vertical array, and notches 9 corresponding to the longitudinal stiffeners 6 are opened on the outer walls of the ring stiffeners 8 inside the tank 1 and the inner walls of the ring stiffeners 8 outside the tank 1, respectively. Through mounting holes 10 are also opened on the inner walls of the notches 9; nuts 11 are inserted into the mounting holes 10 and threaded together with the screw holes 7.

[0027] The specific operating principle of the first pressure-resistant strengthening mechanism 4 in conjunction with the chemical storage tank is as follows:

[0028] Several longitudinal stiffeners 6 are fixedly installed in a ring array on the inner and outer walls of the tank body 1, forming a longitudinal support system evenly distributed along the circumference of the tank body. Several screw holes 7 are vertically arrayed on the side walls of the longitudinal stiffeners 6, providing a foundation for the subsequent connection of the ring stiffeners 8. At the same time, several ring stiffeners 8 are fitted in a vertical array on the inner and outer walls of the tank body 1. Notches 9 corresponding to the longitudinal stiffeners 6 are respectively opened on the inner and outer walls of the ring stiffeners 8 located inside and outside the tank body. The through mounting holes 10 opened on the inner wall of the notches 9 correspond to the screw holes 7 on the longitudinal stiffeners 6. The ring stiffeners 8 are fitted onto the longitudinal stiffeners 6 on the inner and outer walls of the tank body 1 through the notches 9, respectively. Then, by inserting nuts 11 into the mounting holes 10 and threading them into the screw holes 7, the ring stiffeners 8 and the longitudinal stiffeners 6 are tightly fixed together, thereby constructing a support system on the inner and outer walls of the tank body 1 composed of longitudinal stiffeners 6 and ring stiffeners 8. The interlocking three-dimensional support network structure can distribute pressure from various directions, such as pressure from the storage medium on the inner wall, external forces from the external environment, and static pressure generated by the gravity of the medium, to the longitudinal stiffeners 6 and annular stiffeners 8. Utilizing the longitudinal bearing capacity of the longitudinal stiffeners 6 and the circumferential restraint capacity of the annular stiffeners 8, the network jointly resists the pressure on the tank body 1, enhancing its overall rigidity and pressure resistance. This effectively improves the deformation resistance of the tank body 1 under complex pressure environments, reduces the probability of deformation, cracking, and other damage caused by internal and external pressure, and ensures the stability and integrity of the tank body 1 structure. This, in turn, ensures the safe and reliable storage of various chemical substances in the chemical storage tank, reduces safety hazards such as leakage of the storage medium due to damage to the tank body 1, improves the safety and reliability of the chemical storage tank, and extends its service life.

[0029] Example 2:

[0030] like Figure 4 As shown, the upper base 12 is fixedly installed at the bottom of the tank 1, and the lower base 13 is located below the upper base 12. Grooves 14 are respectively provided on the opposite walls of the upper base 12 and the lower base 13, and several horizontal stiffeners 15 and vertical stiffeners 16 are fixedly installed inside the grooves 14, forming a mesh structure between the several horizontal stiffeners 15 and vertical stiffeners 16. Fixing rings 17 are fixedly installed between the opposite walls of the upper base 12 and the lower base 13, and the upper and lower ends of the rubber seat 18 are fixedly installed inside the rings of the fixing rings 17. Several connecting rods 19 are also fixedly installed between the opposite walls of the upper base 12 and the lower base 13 in a ring array, and the two ends of the rubber seat 18 are respectively fitted and fixedly installed on the outer walls of the upper and lower symmetrical connecting rods 19.

[0031] The second pressure-strengthening mechanism 5 further complements the specific operating principle of this chemical storage tank as follows:

[0032] The upper base 12 is fixedly installed at the bottom of the tank body 1, and the lower base 13 is placed below the upper base 12. The upper and lower bases are arranged opposite to each other. Interlocking transverse stiffeners 15 and longitudinal stiffeners 16 are fixedly installed in the grooves 14 opened on the opposite walls of the upper base 12 and the lower base 13. The mesh structure formed by them increases the strength and rigidity of the upper and lower bases, enabling them to better withstand pressure. The fixing ring 17 installed between the opposite walls of the upper base 12 and the lower base 13 is used to fix the upper and lower ends of the rubber seat 18, so that the rubber seat 18 is stably positioned between the upper and lower bases. This not only provides additional support for the rubber seat 18 but also restricts its range of motion. Meanwhile, several connecting rods 19 are fixedly installed in a circular array between the opposing walls of the upper base 12 and the lower base 13, and springs 20 are fixedly installed between the symmetrically arranged connecting rods 19. When the tank 1 is subjected to pressure, the pressure is first transmitted to the upper base 12. At this time, the mesh structure formed by the transverse stiffeners 15 and the longitudinal stiffeners 16 helps to disperse and bear the pressure, ensuring the stability of the entire structure. Then, the pressure is distributed to the lower base 13 through the rubber seat 18 and springs 20. 3. During this process, the rubber seat 18 absorbs the energy generated by the pressure impact using its good elasticity and buffering performance. The spring 20 further enhances the buffering effect and restores the tank to its original shape after the pressure disappears. This second pressure-resistant strengthening mechanism 5, composed of the upper base 12, lower base 13, rubber seat 18, spring 20, transverse stiffener 15, longitudinal stiffener 16, fixing ring 17, and connecting rod 19, further enhances the pressure resistance and stability of the bottom of the tank 1. On the one hand, it effectively reduces the pressure caused by uneven force distribution or large pressure impacts on the bottom of the tank 1. In the event of tilting, deformation, or damage, the integrity of the tank body 1 structure is ensured. On the other hand, the buffering effect of the rubber seat 18 and spring 20 reduces the impact of pressure on the tank body 1, reduces the damage of vibration to the tank body 1, and extends the service life of the tank body. At the same time, the mesh structure formed by the transverse stiffeners 15 and longitudinal stiffeners 16 in the upper and lower bases further improves the load-bearing capacity of the upper and lower bases, enabling the tank body to be placed more stably, ensuring the safety and reliability of the chemical storage tank when storing chemical substances, and reducing the safety risks caused by problems at the bottom of the tank body.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
