Description

Technical Field

[0001] The utility model relates to the technical field of material storage devices, in particular to a material storage system suitable for water transportation. Background Art

[0002] In the field of water transportation, storage tanks are widely used in the transportation and storage of various chemicals, foods, pharmaceuticals, and other materials. However, traditional storage tanks have certain deficiencies in terms of sealing performance and material protection. Especially during long-term water transportation, factors such as external air, water vapor, and vibration often have adverse effects on the materials inside the storage tanks, such as oxidation, contamination, and volatilization. This not only reduces the purity and quality of the materials, but also may pose safety risks.

[0003] While existing storage devices have implemented some sealing measures to address these issues, the sealing effect is often less than ideal. For example, some storage tanks use simple mechanical seals or rubber seals. However, these seals are prone to aging, wear, loosening, and corrosion over time and in vibration environments, resulting in a decrease in sealing performance and an inability to effectively prevent the intrusion of air and moisture. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a storage system suitable for water transportation, which has the advantages of multiple sealing structures and uses vacuum belts for sealing and isolation, and solves some problems raised in the background technology.

[0006] Furthermore, the left end of the sealing ball is fixedly connected to a rotating rod, the left end of the rotating rod passes through the tank mouth and is fixedly installed with a handwheel, the outer side of the rotating rod is fixedly sleeved with a sealing bearing at the intersection with the tank mouth, the outer ring of the sealing bearing is fixedly connected to the tank mouth, and a locking part is provided on the rotating rod at the left side of the tank mouth, and the rotating rod can be locked by the locking part to avoid accidental collisions and other accidents that cause the sealing ball to rotate and affect the sealing effect. At the same time, when in use, you only need to take out the locking part directly, which is simple to operate.

[0007] Furthermore, a vacuum sensor is integrated on the two-way air valve, and a detachable vacuum pump is fixedly installed on the right end of the two-way air valve. The vacuum pump and the vacuum sensor are connected via wireless technology signals, and the vacuum pump is fixedly connected to the storage tank. Through the integrated design of the vacuum sensor, the vacuum environment at the tank mouth can be effectively maintained.

[0008] Furthermore, a sealing sleeve is fixedly installed at the corresponding sliding rod at the lower end of the ball disc on the lower side, and the sealing sleeve is slidably sleeved on the outer side of the sliding rod. The outer side of the sliding rod is fixedly sleeved with a limiting sleeve at the lower end near the tank cover. The sealing sleeve can improve the sealing between the sliding rod and the ball disc on the lower side to avoid liquid leakage.

[0009] Furthermore, the upper end of the slide rod passes through the tank cover and extends to the outside. The upper end of the slide rod is threadedly connected to a fastening bolt. The upper end of the slide rod is fixedly connected to the tank cover through the fastening bolt.

[0010] Furthermore, a sealing ring 1 is provided on the ball disc at the connection with the sealing ball, and the diameter of the sealing ring 1 is larger than the diameter of the inlet and outlet grooves and the through hole on the ball disc. A sealing ring 2 is provided at the outer ring position of the upper end of the sealing base, that is, the sealing ring 1 and the sealing ring 2 can not only improve the sealing between the structures, but also further improve the sealing between the structures under the promotion of negative pressure during vacuuming, thereby achieving a complementary effect.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model uses a vacuum pump and a two-way air valve in combination with an exhaust pipe to vacuum the tank mouth, and uses the vacuum state to form a negative pressure area, effectively preventing the intrusion of external air and water vapor, greatly improving the sealing performance of the storage tank.

The diameter of the sealing ring 19 is larger than the diameter of the through hole on the inlet and outlet grooves 5 and the ball disc 3. When in use, turn on the vacuum pump 12 and the two-way air valve 11, and the enclosed space in the tank mouth 2 can be vacuumed through the exhaust pipe 10. The stability of the vacuum state can be guaranteed by the close fit between the structures and the sealing bearing 8 and the sealing ring 19 and other structures. By making the interior of the tank mouth 2 a vacuum state, a negative pressure area can be formed, which effectively prevents outside air and water vapor from entering the interior of the storage tank 1, and prevents internal gas leakage or material evaporation, etc. In this way, not only the sealing performance of the storage tank 1 is improved, but also the purity and quality of the internal material are ensured. Especially in scenarios where it is necessary to prevent material oxidation, contamination or volatilization, the vacuum belt sealing effect is particularly significant.

[0021] See also Figure 3-Figure 4 The left end of the sealing ball 4 is fixedly connected with a rotating rod 6, and the left end of the rotating rod 6 passes through the tank mouth 2 and is fixedly installed with a hand wheel 7. The outer side of the rotating rod 6 is fixedly sleeved with a sealing bearing 8 at the intersection with the tank mouth 2, and the outer ring of the sealing bearing 8 is fixedly connected to the tank mouth 2. A locking piece 9 is provided on the rotating rod 6 at the left side of the tank mouth 2. When the tank mouth 2 is opened, the tank cover 16 can be directly removed by loosening the fastening bolt 17, and then the hand wheel 7 is turned to make the rotating rod 6 drive the sealing ball 4 to rotate, so that the inlet and outlet grooves 5 and the through holes of the ball disc 3 correspond to each other, and a channel for material in and out can be formed. It is worth mentioning that the sealing base 14 will be separated and moved downward between the ball disc 3 under the action of gravity or other operations until it stops when the limit sleeve 18 contacts the limit between the upper ball disc 3, thereby releasing the restriction on the through hole of the lower ball disc 3.

[0022] See also Figure 1-Figure 2A vacuum sensor is integrated on the two-way air valve 11, and a detachable vacuum pump 12 is fixedly installed on the right end of the two-way air valve 11. The vacuum pump 12 and the vacuum sensor are connected through wireless technology signals. The vacuum pump 12 is fixedly connected to the storage tank 1 for the above-mentioned vacuum operation. The vacuum environment can be detected by the integrated vacuum sensor. When it is lower than the set threshold, an instruction is sent to the vacuum pump 12 to realize automatic vacuum operation.

[0023] See also Figure 2-Figure 3 The lower end of the lower ball disc 3 is fixedly installed with a sealing sleeve 15 at the corresponding slide rod 13. The sealing sleeve 15 is slidably sleeved on the outer side of the slide rod 13. The outer side of the slide rod 13 is fixedly sleeved with a limiting sleeve 18 at the lower end near the tank cover 16. The upper end of the slide rod 13 passes through the tank cover 16 and extends to the outside. The upper end of the slide rod 13 is threadedly connected with a fastening bolt 17. The upper end of the slide rod 13 is fixedly connected to the tank cover 16 by the fastening bolt 17. The upper end of the sealing base 14 is provided with a sealing ring 20 at the outer ring position. After the upper end of the slide rod 13 passes through the tank cover 16, it can be tightened to the tank cover by screwing the fastening bolt 17. 16 is used to limit and fix the seal to prevent it from loosening. At the same time, the sealing base 14 at the lower end of the slide rod 13 will also be stuck in the through hole of the lower ball disc 3 during the process of screwing the fastening bolt 17. In addition, during the vacuum process, the sealing base 14 will also be pushed by the air pressure to cooperate with the sealing ring 20 to make it fit more tightly with the through hole of the lower ball disc 3, thereby further improving the sealing performance at the tank mouth 2. At the same time, it can effectively prevent the chemical materials inside the storage tank 1 from entering the interior of the tank mouth 2 when the hull shakes and causing erosion to the sealing ball 4 and other structures, thereby ensuring the service life of the device.

[0024] Working principle: When in use, turn on the vacuum pump 12 and the two-way air valve 11, and the enclosed space in the tank mouth 2 can be vacuumed through the exhaust pipe 10. The stability of the vacuum state can be guaranteed by the close fit between the structures and the sealing bearing 8 and the sealing ring 19. Therefore, by making the interior of the tank mouth 2 a vacuum state, a negative pressure area can be formed, which effectively prevents external air and water vapor from entering the interior of the storage tank 1, and prevents internal gas leakage or material evaporation, etc. Further, after the upper end of the sliding rod 13 passes through the tank cover 16, it can be tightened to the tank cover 1 by screwing the fastening bolt 17. 6 is limited and fixed to prevent loosening. At the same time, the sealing base 14 at the lower end of the slide rod 13 will also be stuck in the through hole of the lower ball disc 3 during the process of screwing the fastening bolts 17. In addition, during the vacuum process, the sealing base 14 will also be pushed by the air pressure to cooperate with the sealing ring 20 to make it fit more tightly with the through hole of the lower ball disc 3. When opening the tank mouth 2, the tank cover 16 can be directly removed by loosening the fastening bolts 17, and then the hand wheel 7 is turned to make the rotating rod 6 drive the sealing ball 4 to rotate, so that the inlet and outlet grooves 5 correspond to the through hole of the ball disc 3 to form a channel for material to enter and exit.
