Description

Technical Field

[0001] The present invention relates to the technical field of chemical oil storage tanks, in particular to a chemical liquid transportation surge-proof storage tank. Background Art

[0002] With the development of the petrochemical industry, oil storage tanks are playing an increasingly important role in transportation, storage, and processing, leading to the construction and use of more and more oil tanks. However, under the influence of marine environments, transportation conditions, and severe weather, the liquid inside the tanks can surge, posing a safety hazard and requiring appropriate protective measures.

[0003] Most traditional anti-surge measures are achieved by setting multiple wave-breaking plates at the inner end of the liquid tank, dividing the inner end of the liquid tank into multiple spaces, and using the wave-breaking plates to block and buffer the oil in the surge state, thereby reducing the amplitude of the oil surge. There are two main ways to install the wave-breaking plates. One is to install the wave-breaking plates at the top position inside the liquid tank. This installation method is more effective in suppressing oil surges when the filling coefficient of the liquid tank is large, that is, when the oil is full. The other is to install the wave-breaking plates at the bottom position inside the liquid tank. This installation method is more effective in suppressing oil surges when the filling coefficient is small, that is, when the oil is shallow. Although these two installation methods can suppress the occurrence of surges under certain circumstances, the suppression effects are different in different situations, and the amount of oil transported by the liquid tank will also be adjusted according to actual needs.

[0004] In order to address the above problems, there is an urgent need for a chemical liquid transportation surge-proof storage tank. Summary of the Invention

[0010] As a further improvement of the present technical solution, the end of the positioning column is in an arc-shaped structure, and the cross-sectional dimension of the end of the positioning column is smaller than the cross-sectional dimensions of the remaining positions.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the chemical liquid transportation surge protection storage tank, it is necessary to drive each adjustment ring to rotate along the inner end of the clamping groove at the corresponding position through the driving component, and adjust the adjustment ring to drive the inner baffle to adjust the position. During the transportation process, when encountering brakes, the oil will sway in the braking direction. The arched surface formed by each inner baffle is used to buffer and block the oil in the surging state, slow down and offset the surge caused by braking, and improve the stability of the oil during transportation. At the same time, the position of each inner baffle can be adaptively adjusted according to the oil level height to cope with surge processing of different oil transportation volumes and improve the surge protection effect.

[0017] 2. In the chemical liquid transport surge-proof storage tank, the grooves are provided to increase the contact point between the inner partition arch surface and the surge, thereby increasing the contact time between the surge and the arch surface, and increasing the residence time of the surge on the inner partition arch surface, thereby further improving the surge-proof effect of the inner partition.

[0018] 3. In the chemical liquid transport surge-proof storage tank, the contact area between the outer side of the adjustment ring and the inner wall of the outer tank is reduced by the provided roller. The contact area is proportional to the friction resistance. Reducing the contact area means reducing the friction resistance generated between the two, thereby reducing the obstruction encountered during the rotation of the adjustment ring and improving the position adjustment efficiency of the adjustment ring.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1-8 As shown, a surge-proof storage tank for chemical liquid transportation is provided, including an outer tank 10 and an inner tank 20 installed at the inner end of the outer tank 10. A liquid inlet and a liquid discharge port are connected between the outer tank 10 and the inner tank 20. A plurality of clamping grooves 210 are provided on the side of the inner tank 20. The inner end of the clamping groove 210 is rotatably connected to a positioning ring 230. A side port that is connected to the inner end of the inner tank 20 is provided on the side of the positioning ring 230. An inner baffle 231 is provided at the inner end of the side port. The inner baffle 231 has an arched structure. A driving assembly is connected between each positioning ring 230. Under the action of the driving assembly, each positioning ring 230 is driven to rotate synchronously along the inner end of the clamping groove 210 at the corresponding position. A limiting assembly is connected between the side of the positioning ring 230 and the inner end of the clamping groove 210. Under the action of the limiting assembly, the inner baffle 231 is positioned.

[0032] In order to address the above problems, during the oil transportation through the storage tank, the oil is first introduced into the inner end of the inner tank 20 through the liquid inlet for storage, and the rising changes of the oil level in the inner tank 20 are observed to complete the oil storage. At this time, the oil level at the inner end of the inner tank 20 is determined. In the present invention, when the oil level is lower than 2 / 3 of the storage height at the inner end of the inner tank 20, it is marked as a low oil level. At this time, it is necessary to drive each adjusting ring 230 to rotate along the inner end of the clamping groove 210 at the corresponding position through the driving component, so that the bottom surface of the inner partition 231 rotates to the bottom position of the inner end of the inner tank 20 along with the adjusting ring 230, and the position of the adjusting ring 230 is positioned by the limiting component, so that the top of the inner partition 231 is kept parallel to the center of the cross section of the inner tank 20. When the oil level is not lower than 2 / 3 of the storage height at the inner end of the inner tank 20, The mark is a high oil level. At this time, each adjusting ring 230 is driven by the driving component to rotate along the inner end of the clamping groove 210 at the corresponding position, so that the bottom surface of the inner baffle 231 rotates to the top position of the inner end of the inner tank 20 along with the adjusting ring 230. The position of the adjusting ring 230 is positioned by the limiting component, so that the bottom end of the inner baffle 231 is kept parallel to the center of the cross section of the inner tank 20. During transportation, when braking, the oil will shake in the braking direction. The arched surface formed by each inner baffle 231 is used to buffer and block the oil in the surging state, slow down and offset the surge caused by braking, and improve the stability of the oil during transportation. At the same time, the position of each inner baffle 231 can be adaptively adjusted according to the oil level height to cope with surge processing of different oil transportation volumes and improve the surge protection effect.

[0033] In addition, the driving assembly includes a servo motor 120 and various connecting plates 121 installed on the side of the servo motor 120. The side ends of each connecting plate 121 are connected to the side of the positioning ring 230, and a number of connecting blocks 240 are connected between two adjacent positioning rings 230. When the position of the inner partition 231 needs to be adjusted, the servo motor 120 needs to be started, and the servo motor 120 drives the various connecting plates 121 to rotate synchronously. The connecting plates 121 will drive the positioning rings 230 connected thereto to rotate, and the two adjacent positioning rings 230 are connected through various connecting blocks 240. When one of the positioning rings 230 is in a rotating state, the remaining positioning rings 230 will follow it to rotate synchronously, thereby driving the various inner partitions 231 to perform synchronous position adjustment, so that the positions of the various inner partitions 231 always remain consistent.

[0034] When the adjusting ring 230 rotates along the inner end of the servo motor 120 at the corresponding position, the side rings at both sides respectively rotate synchronously with the inner end of the slide groove 220 at the corresponding position. At the same time, the adjusting ring 230 is supported by the side rings and the slide groove 220, thereby reducing the support burden of the connecting plate 121 and improving the stability of the adjusting ring 230 during rotation.

[0035] Furthermore, the limit assembly includes a pair of positioning posts 233 and a pair of sockets 221. Side holes 232 are provided on the upper and lower sides of the side ring. The positioning posts 233 are plugged into the inner ends of the side holes 232, and a limiting spring 234 is connected between the end of the positioning post 233 and the inner wall of the side hole 232. The two sockets 221 are respectively provided at the upper and lower ends of the inner side of the slide groove 220, and the end of the positioning post 233 is plugged into the inner end of the socket 221. In the initial state, the inner partition 231 is at the bottom position of the inner end of the inner tank 20. At this time, the two positioning posts 233 are just inserted into the inner ends of the sockets 221 at the corresponding positions. When the position of the adjustment ring 230 needs to be adjusted, the servo motor is used to adjust the position. 120 drives the adjusting ring 230 to rotate along the inner end of the clamping groove 210. At this time, the positioning column 233 follows the adjusting ring 230 to detach from the inner end of the socket 221 at the corresponding position, and its end will be squeezed by the inner wall of the clamping groove 210, prompting the positioning column 233 to move toward the inner end of the side hole 232 and squeeze the limit spring 234 until the end of the positioning column 233 is aligned with the opening of the other socket 221. At this time, the limit spring 234 in the compressed state will drive the positioning column 233 to move toward the inner end of the socket 221 and re-fix the position of the adjusting ring 230. At this time, the inner partition 231 is adjusted from the bottom position of the inner end of the inner tank 20 to the top position, thereby improving the position correction effect of the inner partition 231.

[0036] When the positioning post 233 is driven by the adjusting ring 230 to detach from the inner end of the socket 221, its end will be restricted by the opening of the socket 221, and this restriction effect is proportional to the contact area of ​​the end of the positioning post 233. Specifically, the end of the positioning post 233 has an arc-shaped structure, and the cross-sectional size of the end of the positioning post 233 is smaller than the cross-sectional size of the other positions. The end of the positioning post 233 is designed to have an arc-shaped structure, which reduces the contact area between the end of the positioning post 233 and the opening of the socket 221, thereby improving the efficiency of the positioning post 233 detaching from the inner end of the socket 221 and reducing the obstruction of the socket 221 to the positioning post 233.

[0037] As the oil surface shakes due to vehicle braking, the surge generated will come into contact with the arch surface of the inner baffle 231, and the arch surface will block and buffer the surging oil, thereby offsetting the surge power. In addition, the arch surface of the inner baffle 231 is provided with a number of grooves, and each groove is equidistantly arranged on the side of the inner baffle 231. The grooves are arranged to increase the contact point between the arch surface of the inner baffle 231 and the surge, increase the contact time between the surge and the arch surface, and increase the residence time of the surge on the arch surface of the inner baffle 231, thereby further improving the surge prevention effect of the inner baffle 231.

[0038] During the position adjustment process, the positioning ring 230 will not only be affected by the friction resistance generated by the side wall of the clamping groove 210 and the side of the positioning ring 230, but its outer side will also contact the inner wall of the outer tank 10, and friction resistance will also be generated between the two. This friction resistance will hinder the rotation of the positioning ring 230, affecting the position adjustment effect of the positioning ring 230. Furthermore, a number of outer grooves 236 are provided on the outer side of the positioning ring 230, and the inner end of each outer groove 236 is rotatably connected to a roller 237, and the end of the roller 237 contacts the inner wall of the outer tank 10. The contact area between the outer side of the positioning ring 230 and the inner wall of the outer tank 10 is reduced by the provision of the roller 237. The contact area is proportional to the friction resistance. Reducing the contact area means reducing the friction resistance generated between the two, thereby reducing the obstruction encountered by the positioning ring 230 during rotation and improving the position adjustment efficiency of the positioning ring 230.

[0039] Since the outer tank 10 is in a sealed state, the transport personnel cannot observe the position changes of each adjusting ring 230 through the outer tank 10 in time, and thus cannot determine the alignment position of the inner partition 231. Furthermore, a number of scale grooves 235 are provided on the edge positions on both sides of the adjusting ring 230, and a transparent plate 130 is provided on the outer side of the outer tank 10 to align with the adjusting ring 230. The set scale grooves 235 and the transparent plate 130 provide a reference point for the transport personnel. The transport personnel can observe the position changes of the scale grooves 235 on the outer side of the adjusting ring 230 at the corresponding position through the transparent plate 130, determine the alignment position of the inner partition 231 in the current state, and thus determine the amount of oil that the inner partition 231 is suitable for transporting.

[0040] Since the bottom end of the outer tank 10 is an arc-shaped structure, the fixing work during transportation is relatively cumbersome and it is easy to move, resulting in violent shaking when the vehicle brakes, which increases the surge level. In addition, a pair of bases 110 are provided at the bottom end of the outer tank 10, and a ring is connected between the top of the base 110 and the outside of the outer tank 10. The bases 110 are provided to symmetrically support the two sides of the bottom end of the outer tank 10, thereby improving the stability of the outer tank 10 during transportation and further reducing the surge level caused by braking.
