Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a high-strength pressure vessel. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses and plays an important role in many sectors such as industry, civil and military industries, as well as in many fields of scientific research. It is most widely used in the chemical and petrochemical industries. In the chemical and petrochemical fields, pressure vessels are mainly used in process processes such as heat transfer, mass transfer and reaction, as well as in the storage and transportation of pressurized gases or liquefied gases.

[0003] The utility model with the existing authorization announcement number CN216202439U discloses a pressure vessel with high strength, pressure resistance and long service life, including a pressure vessel body, the pressure vessel body including a base layer, a first functional layer and a second functional layer, the first functional layer including a high alloy medium carbon layer and a nickel-chromium alloy layer, the second functional layer including a silicide fiber layer and a polyvinyl chloride resin layer, and support legs are fixedly installed around the bottom of the pressure vessel body.

[0004] By adopting the above technical scheme, the carbon layer in the high alloy has the effect of high strength, and the nickel-chromium alloy layer has the effects of high strength, corrosion resistance and rust prevention. By setting the protective plate and the spring, the pressure resistance effect can be achieved, which solves the problem that the existing pressure vessels have low strength and short service life, making them inconvenient for people to use.

Moreover, it is very troublesome to move the pressure vessel after placement, and it needs to be lifted by external machinery. During the lifting process, it is very easy to collide with foreign objects, causing damage to the pressure vessel, which not only reduces the applicability of the pressure vessel, but also reduces the use effect of the pressure vessel.

[0026] The mobile protection mechanism 3 includes an auxiliary platform 301, which is located outside the pressure vessel body 1. Two support blocks 6 are fixedly connected to the upper surface of the auxiliary platform 301, one group of support blocks 6 is internally rotatably connected to a bidirectional threaded rod 7, and the outer surface of the bidirectional threaded rod 7 is threadedly connected to two clamping plates 8, each clamping plate 8 is slidably connected to the inside of the two support blocks 6, and the rotation of the bidirectional threaded rod 7 is utilized to drive the two clamping plates 8 to move closer to or away from each other inside the support block 6, thereby limiting the position of the pressure vessel body 1 and improving the protection capability of the pressure vessel body 1.

[0027] Two groups of dampers 303 are fixedly connected to the inner bottom wall of the auxiliary platform 301, and the top ends of the two groups of dampers 303 are fixedly connected to a placement plate 302. The inner wall of the support block 6 is inlaid with an auxiliary bearing 11, and the inner wall of the inner ring of the auxiliary bearing 11 is fixedly connected to the outer surface of the bidirectional threaded rod 7. The auxiliary bearing 11 can reduce the friction generated by the bidirectional threaded rod 7 during rotation, making the bidirectional threaded rod 7 more sensitive during rotation. At the same time, it can also reduce the wear of the bidirectional threaded rod 7 and increase the service life of the bidirectional threaded rod 7.

[0028] The upper surface of the placement plate 302 is in contact with the bottom surface of the pressure vessel body 1, and an auxiliary spring 304 is sleeved on the outside of each group of dampers 303.

[0031] The working principle of the utility model is as follows: when in use, firstly connect the power supply to the hydraulic rod 305, then place the pressure vessel body 1 inside the auxiliary platform 301 so that it contacts the placement plate 302, then rotate the handle 10, thereby rotating the rotating wheel 9 and the bidirectional threaded rod 7, the auxiliary bearing 11 can improve the sensitivity of the bidirectional threaded rod 7 during rotation, thereby making the two clamping plates 8 approach each other and contact the pressure vessel body 1, and utilizing the two clamping plates 8 to limit the position of the pressure vessel body 1, while relying on the cooperation of the protective spring 4 and the protective shell 5 to protect the pressure vessel body 1 during the placement process, the support column 13 and the anti-sliding block 14 can increase the stability during the placement, and when the pressure vessel body 1 needs to be sealed, rely on the threaded pipe 203 and the sealing cover 204 to connect them by matching threads, thereby performing the first sealing on the through pipe 201, and then rotating the upper flange 20 5 so that it is parallel to the aperture of the lower flange 202, and then the fixing bolts 206 are threadedly connected in the upper flange 205 and the lower flange 202, so as to further improve the sealing effect and realize the high sealing ability of the pressure vessel body 1. When it is necessary to move the position, the hydraulic rod 305 is started to make the lifting block 306 descend, so that the universal wheel 307 contacts the ground and the auxiliary platform 301 is lifted up. At this time, the universal wheel 307 can be used to conveniently move the position of the pressure vessel body 1. The elasticity of the auxiliary spring 304 and the damping effect of the damper 303 can reduce the shaking of the pressure vessel body 1 during movement and avoid damage during the movement. When it is moved to a suitable position, the hydraulic rod 305 can be started again to make the universal wheel 307 rise and make the support column 13 contact the ground, which not only increases the applicability of the pressure vessel, but also improves the use effect of the pressure vessel.
