Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessels, and particularly to a highly sealed pressure vessel. Background Art

[0002] Pressure vessels with a design pressure p in the range of 10.0 MPa ≤ p < 100.0 MPa are widely used in chemical production. For example, the outer shells of ammonia synthesis towers, urea synthesis towers, copper scrubbing towers, carbon monoxide cold extraction towers, etc. are all high-pressure vessels.

[0003] The patent application with the Chinese patent application number CN202221938032.2 discloses a highly sealed pressure vessel. Although this application realizes preventing the overall sealing performance from being affected by the loosening of the sealing cover, after the sealing cover is screwed together, the clamping rod is rotated to fit the inner wall of the sealing cover, and with the cooperation of the clamping bolt, the clamping of the sealing cover is realized, achieving good sealing performance. However, when storing liquefied gas, it is necessary to pressurize the inside of the pressure vessel to fill the liquefied gas into the pressure vessel. Generally, the liquefied gas is directly filled into the pressure vessel, resulting in the generation of bubbles inside the pressure vessel. When the bubbles collapse, microjets are generated to impact the surface of the container, causing pitting corrosion. This problem needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a highly sealed pressure vessel to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A highly sealed pressure vessel, including support legs, further including a support assembly. The inner side of the support legs is fixedly connected with a high-pressure vessel, and the middle of the top of the high-pressure vessel is fixedly connected with a feed port.

[0006] Among them, the support assembly includes: A fixed cylinder, the fixed cylinder is fixedly connected to the middle of the inner bottom of the high-pressure vessel. The middle part of the fixed cylinder is fixedly connected with a support circular plate. The top of the support circular plate is fixedly connected with a support spring. The top of the support spring is fixedly connected with a lifting seat. The middle of the top of the lifting seat is fixedly connected with a support column. The top of the support column is fixedly connected with a buffer head. The support spring can support the support spring.

[0007] According to the above technical solution, it further includes an adjustment assembly, and the adjustment assembly is composed of a positioning frame, a rotating block, a first guide plate, a fixed arm, a guide pulley, and a guide chute.

[0008] The positioning frame is fixedly connected to the bottom of the buffer head. The rotating block is rotatably connected to the middle part inside the positioning frame. The first deflector is fixedly connected to the side of the rotating block away from the positioning frame. The fixed arm is fixedly connected to the outside of the fixed cylinder near the top. The guiding pulley is rotatably connected to the side of the fixed arm away from the fixed cylinder. The guiding chute is fixedly connected to the side of the first deflector close to the fixed cylinder. The rotating block can rotate in the middle part inside the positioning frame.

[0009] According to the above technical solution, it further includes a telescopic assembly, and the telescopic assembly is composed of a fixed cross plate, a fixed spring, a sliding seat, a second deflector, a rotating frame and a guiding roller.

[0010] The fixed cross plate is fixedly connected to the middle part inside the first deflector. The fixed spring is fixedly connected to the side of the fixed cross plate away from the rotating block. The sliding seat is fixedly connected to the end of the fixed spring away from the fixed cross plate. The second deflector is fixedly connected to the other side of the sliding seat. The rotating frame is fixedly connected to the side of the second deflector away from the sliding seat. The guiding roller is rotatably connected to the middle part inside the rotating frame. The fixed spring can support the sliding seat and the second deflector.

[0011] According to the above technical solution, the top end of the support column penetrates through the top of the fixed cylinder and extends above the fixed cylinder to be connected to the buffer head. When the buffer head moves up and down, the lifting seat can be driven to move up and down through the support column.

[0012] According to the above technical solution, a first diversion groove is formed at the top of the first deflector, and a second diversion groove is formed at the top of the second deflector. The first diversion groove and the second diversion groove can divert the liquefied gas.

[0013] According to the above technical solution, a rectangular groove for accommodating the movement of the second deflector is formed on the left side inside the first deflector. The sliding seat and the second deflector can slide inside the first deflector.

[0014] According to the above technical solution, the guiding pulley is arranged inside the guiding chute. The fixed arm can be slidably connected to the inner wall of the guiding chute through the guiding pulley. The guiding pulley can slide inside the guiding chute.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. Through the step-by-step diversion of buffer head → first deflector → second deflector → guiding roller, the liquefied gas is forced to flow along the inner wall of the container, reducing the conversion of liquid kinetic energy into heat energy and inhibiting flashing and bubble generation; 2. The guiding roller abuts against the inner wall of the high-pressure container, directly transferring the liquefied gas to the metal wall surface inside the high-pressure container, and using the high thermal conductivity of the high-pressure container to quickly dissipate heat, maintaining the low-temperature state and further reducing the gasification risk; 3. During low-pressure filling, the buffer head remains at a high position, the first flow guide plate and the second flow guide plate unfold, extending the flow path of the liquefied gas to ensure sufficient contact between the liquefied gas and the flow guide structure; 4. During high-pressure filling, the buffer head is pressed downward, then the inclination angle of the first flow guide plate is increased, and the second flow guide plate is contracted, which can shorten the residence time of the liquefied gas on the flow guide plate. At the same time, it lengthens the flow path of the liquefied gas along the inner wall of the high-pressure container, forcing the liquefied gas to flow along the inner wall of the container, and using the principle of gravity-accelerated falling to shorten the filling cycle; 5. By setting the buffer head and the support spring, the support spring can absorb the impact energy during high-speed filling and reduce the impact intensity of the liquefied gas. The flow guide rollers are in rolling contact with the inner wall of the high-pressure container, converting the concentrated impact force into rolling friction dissipation, avoiding local stress concentration, and being able to reduce the fatigue risk of the bottom weld of the tank.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0020] Example 1, please refer to Figures 1-3 , the present invention provides a technical solution: a highly sealed pressure vessel, including support legs 1, and further including a support assembly 4. A high-pressure vessel 2 is fixedly connected to the inner side of the support legs 1, and a feed port 3 is fixedly connected to the middle of the top of the high-pressure vessel 2.

[0021] Among them, the support assembly 4 includes: A fixed cylinder 401, the fixed cylinder 401 is fixedly connected to the middle of the inner bottom of the high-pressure vessel 2. A support circular plate 402 is fixedly connected to the middle of the inner part of the fixed cylinder 401. A support spring 403 is fixedly connected to the top of the support circular plate 402. The top end of the support spring 403 is fixedly connected to a lifting seat 404. A support column 405 is fixedly connected to the middle of the top of the lifting seat 404. A buffer head 406 is fixedly connected to the top of the support column 405. The support spring 403 can support the support spring 403.

[0022] The top end of the support column 405 penetrates through the top of the fixed cylinder 401 and extends above the fixed cylinder 401 to be connected to the buffer head 406. When the buffer head 406 moves up and down, it can drive the lifting seat 404 to move up and down through the support column 405.

[0023] Example 2, please refer to Figures 1-8 , on the basis of Example 1, the present invention provides a technical solution: further including an adjustment assembly 5. The adjustment assembly 5 is composed of a positioning frame 501, a rotating block 502, a first deflector 503, a fixed arm 504, a guide pulley 505, and a guide chute 506.

[0024] The positioning frame 501 is fixedly connected to the bottom of the buffer head 406. The rotating block 502 is rotatably connected to the middle of the positioning frame 501. The first deflector 503 is fixedly connected to the side of the rotating block 502 away from the positioning frame 501. The fixed arm 504 is fixedly connected to the outer side of the fixed cylinder 401 near the top. The guide pulley 505 is rotatably connected to the side of the fixed arm 504 away from the fixed cylinder 401. The guide chute 506 is fixedly connected to the side of the first deflector 503 near the fixed cylinder 401. The rotating block 502 can rotate in the middle of the positioning frame 501.

[0025] It further includes a telescopic component 6, which is composed of a fixed horizontal plate 601, a fixed spring 602, a sliding seat 603, a second deflector plate 604, a rotating frame 605 and a deflector roller 606.

[0026] The fixed horizontal plate 601 is fixedly connected to the middle part inside the first deflector plate 503. The fixed spring 602 is fixedly connected to the side of the fixed horizontal plate 601 away from the rotating block 502. The sliding seat 603 is fixedly connected to one end of the fixed spring 602 away from the fixed horizontal plate 601. The second deflector plate 604 is fixedly connected to the other side of the sliding seat 603. The rotating frame 605 is fixedly connected to the side of the second deflector plate 604 away from the sliding seat 603. The deflector roller 606 is rotatably connected to the middle part inside the rotating frame 605. The fixed spring 602 can support the sliding seat 603 and the second deflector plate 604.

[0027] A first diversion groove is formed at the top of the first deflector plate 503, and a second diversion groove is formed at the top of the second deflector plate 604. The first diversion groove and the second diversion groove can divert the liquefied gas.

[0028] A rectangular groove for the movement of the second deflector plate 604 is formed on the left side inside the first deflector plate 503. The sliding seat 603 and the second deflector plate 604 can slide inside the first deflector plate 503.

[0029] The guiding pulley 505 is arranged inside the guiding chute 506. The fixed arm 504 can be slidably connected to the inner wall of the guiding chute 506 through the guiding pulley 505, and the guiding pulley 505 can slide inside the guiding chute 506.

[0030] When the pressure is relatively small when the liquefied gas is filled into the high-pressure container 2, the liquefied gas falls and directly contacts the surface of the buffer head 406, and flows downward along the outer wall of the buffer head 406, so that the liquefied gas flowing on the buffer head 406 contacts the top of the first deflector plate 503 and continues to flow downward along the first diversion groove at the top of the first deflector plate 503. At this time, the liquefied gas continues to flow through the second diversion groove at the top of the second deflector plate 604. Subsequently, when the liquefied gas contacts the deflector roller 606, it can continue to flow downward in the high-pressure container 2 along the top of the deflector roller 606. Since the outer side of the deflector roller 606 can abut against the inner wall of the high-pressure container 2, the liquefied gas can be directly transferred from the deflector roller 606 to the inner wall of the high-pressure container 2 and continue to fall to the bottom inside the high-pressure container 2 under the action of gravity, avoiding the generation of bubbles when the liquefied gas is directly filled into the high-pressure container 2.

[0031] When quickly filling with liquefied gas, the falling liquefied gas is ejected at an accelerated speed, causing the liquefied gas to impact the top of the buffer head 406, enabling the buffer head 406 to move downward, synchronously driving the support column 405 and the lifting seat 404 to move downward, compressing the support spring 403. Since the pressure exerted by the liquefied gas on the top of the buffer head 406 is a constant value, the support spring 403 can be continuously compressed to a certain position. When the buffer head 406 moves downward, the positioning frame 501 can squeeze the first deflector 503, causing the rotating block 502 to rotate in the middle of the positioning frame 501. At the same time, the guiding pulley 505 on the fixed arm 504 outside the fixed cylinder 401 slides in the guiding chute 506, causing the first deflector 503 to tilt and rotate relative to the bottom of the buffer head 406. At this time, when the second deflector 604 on the other side of the first deflector 503 moves upward in the high-pressure container 2, the guiding roller 606 outside the second deflector 604 slides upward on the inner wall of the high-pressure container 2, causing the second deflector 604 to move within the first deflector 503, squeezing the fixed spring 602 by the second deflector 604 and the sliding seat 603, causing the fixed spring 602 to contract. At the same time, a part of the second deflector 604 retracts into the first deflector 503, shortening the flow path of the liquefied gas on the first deflector 503 and the second deflector 604, and increasing the flow path of the liquefied gas on the inner wall of the high-pressure container 2. It can quickly guide the liquefied gas, accelerate the speed of the liquid reaching the bottom of the tank, and shorten the filling cycle.
