Description

Technical Field

[0001] This utility model relates to the field of sealing devices, specifically a high-efficiency sealing device for an internal floating disc. Background Technology

[0002] An internal floating roof is a type of floating cover that floats on the surface of the oil in a tank, moving with the rise and fall of the oil. Using this type of internal floating roof to cover the liquid surface is considered the most economical and effective method to reduce oil evaporation losses. Currently, internal floating roofs are typically located inside the storage tank during use. To remove the internal floating roof from the tank, it needs to be placed in a sealed container to prevent oxidation from the air, which could cause rust and affect its use. Therefore, a sealing device is required to ensure the sealing of the floating roof. Currently used sealing devices generally suffer from insufficient limiting and fixing effects, causing the floating roof to easily shake during transfer and transportation, and collide with the inner wall of the sealing seat, resulting in damage. To address this, we propose a high-efficiency sealing device for internal floating roofs. Utility Model Content

[0007] (III) Beneficial Effects

[0008] Compared with the prior art, this utility model provides a high-efficiency sealing device for an internal floating disc, which has the following beneficial effects:

This ensures the stability of the sealing state, enabling the device to maintain a vacuum or low-pressure environment during operation, reducing the potential impact of air on internal components. This not only helps prevent oxidation reactions but also effectively reduces internal pressure, avoiding gas leaks or other safety hazards caused by gas accumulation. Support rods 7 are symmetrically fixed on both sides of the through-hole on the inner surface of the upper cover 1. Springs 9 are fixedly fixed on the outer periphery of the support rods 7 on the inner surface of the upper cover 1. A sponge pad 8 is fixedly connected to the other end of the springs 9. The fixing mechanism includes a base plate 16, a belt 17, a pulley 18, a lead screw 22, and a motor 23. Support blocks are symmetrically fixed on the bottom surface of the base plate 16 at the short axes on both sides. A lead screw 22 rotates between the two support blocks. A pulley 18 is rotatably connected to the middle of the lead screw 22. A belt 17 is driven through the pulley 18. The other end of the belt 17 is driven through the other pulley 18. A motor 23 is also fixedly connected to the bottom surface of the base plate 16. The output shaft of the motor 23 is fixedly connected to the pulley 18, which is not connected to the lead screw 22. The fixing mechanism also includes a clamping block 11, a support sliding frame 12, a slide bar 13, and a slider 20. A slide bar 13 is provided in the middle of the top surface of the base plate 16. Grooves are symmetrically opened on both sides of the slide bar 13. The slider 20 is a cuboid. The bottom surface of the slider 20 has a groove, and protrusions are provided on both sides of the groove. The slider 13 and the slider 20 are engaged and slidably connected through the groove and protrusions. Two sliders 20 are slidably connected to the slider 13. The supporting sliding frame 12 is "n"-shaped. One side of the supporting sliding frame 12 is slidably connected to the lead screw 22, and the inner side of the other side is tightly fitted and fixedly connected to the top surface of the slider 20. A clamping block 11 is fixedly provided on the outer side. The clamping block 11 has an opening, and a rubber pad 19 is fixedly provided on the side wall of the opening. Through the design of the fixing mechanism, the inner floating plate 10 can be stably placed inside the base 4, thereby achieving an effective fixing effect. This innovative fixing mechanism ensures that the inner floating plate 10 remains stable under various conditions and avoids displacement caused by external vibration or movement.This design not only improves the safety of the inner floating roof 10, but also reduces the risk of damage caused by shaking during transportation. A sleeve 21 is fixedly installed in the middle of the upper surface of the slide bar 13. A hole is opened on the surface of the sleeve 21, and a telescopic rod 14 is slidably connected in the hole.

The inner floating roof 10 is engaged in the opening of the clamping block 11 and the upper end of the pressure plate 15.

[0018] Working principle: When the motor 23 is started, the lower pulley 18 rotates and drives the belt 17 for transmission. The upper pulley 18 also rotates, and the lead screw 22 connected to the pulley 18 also rotates. The supporting sliding frame 12 can therefore slide on the lead screw 22, which drives the slider 20 to slide on the slide bar 13. Therefore, the clamping blocks 11 at both ends can hold the inner floating plate 10. The rubber pad 19 wraps around the inner floating plate 10 to reduce the damage caused by collision. The telescopic rod 14 pushes the pressure plate 15 to press against the inner floating plate 10, further preventing the inner floating plate 10 from shaking. Then, the upper cover 1 is covered, and the sponge pad 8 also presses against the inner floating plate 10. Then, the upper cover 1 and the base 4 are connected together by bolts 3. The air valve 2 and the air pipe 5 can allow some of the air in the base 4 to be discharged, delaying the oxidation and rusting process of the inner floating plate 10.
