Description

Technical Field

[0001] This utility model relates to the field of hydrogen compressor exhaust technology, specifically a circulating hydrogen compressor with an exhaust structure. Background Technology

[0002] In the industrial production sector, circulating hydrogen compressors are extremely critical equipment, widely used in many important industries such as petrochemicals, oil refining, and hydrogenation. They are mainly used for the circulation and pressurization of hydrogen to ensure the smooth operation of various processes.

[0003] However, existing circulating hydrogen compressors have some shortcomings in actual operation. Traditional exhaust structures are difficult to adjust the exhaust pressure accurately and flexibly according to different working conditions. When the pressure inside the cylinder is too high, the pressure cannot be released in a timely and effective manner. This can easily lead to damage to equipment components, such as cylinder rupture and seal failure, significantly shortening the service life of the equipment, increasing maintenance costs and downtime, and may also cause serious safety accidents, threatening the lives of operators and the normal operation of production. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a circulating hydrogen compressor with an exhaust structure, which solves the problem that traditional exhaust structures are unable to accurately and flexibly adjust the exhaust pressure according to different working conditions.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A circulating hydrogen compressor with an exhaust structure includes: a base, a cylinder fixedly connected to the outer wall of the top of the base, a crankcase fixedly connected to the outer wall of the cylinder, and an exhaust device, the outer wall of the bottom of the exhaust device being fixedly connected to the inner wall of the top of the cylinder; the exhaust device includes an exhaust pipe, a slide rod fixedly connected to the outer wall of the top of the exhaust pipe, a guide shroud fixedly connected to the outer wall of the top of the slide rod, a fixing frame fixedly connected to the outer wall of the bottom of the guide shroud, a sound-absorbing plate fixedly connected to the inner wall of the guide shroud, a screw rod threadedly connected to the inner wall of the top of the guide shroud, a throttle fixedly connected to the outer wall of the top of the screw rod, a compression plate rotatably connected to the outer wall of the bottom of the throttle, a pressure spring fixedly connected to the outer wall of the bottom of the compression plate, an opening and closing plate slidably connected to the outer wall of the slide rod, a plug fixedly connected to the outer wall of the bottom of the opening and closing plate, and a sealing ring fixedly connected to the outer wall of the plug.

[0009] Preferably, the slide rods are arranged in a ring around the central point of the exhaust pipe, the guide shroud is disposed outside the exhaust pipe, and the inner wall of the fixing frame is fixedly connected to the outer wall of the exhaust pipe. The guide shroud connected to the exhaust pipe by the fixing frame serves to guide the ejected airflow downwards and avoids the airflow from being directly sprayed onto the operator.

[0010] Preferably, the inner wall of the extrusion plate is slidably connected to the outer wall of the slide rod, and the outer wall of the pressure spring on the side away from the extrusion plate is fixedly connected to the outer wall of the top of the opening and closing plate. When the pressure in the cylinder exceeds the pressure of the pressure spring on the opening and closing plate, the high-pressure hydrogen will push the opening and closing plate to slide upward along the slide rod.

[0011] Preferably, the outer wall of the bottom of the opening and closing plate is in contact with the outer wall of the top of the exhaust pipe, and the outer wall of the sealing ring is slidably connected to the inner wall of the exhaust pipe. When the opening and closing plate slides upward along the slide rod, the plug will be pulled out from the exhaust pipe, and the sealing ring will also detach from the inner wall of the exhaust pipe, thus opening the exhaust pipe.

[0012] Preferably, a compressed air pipe is symmetrically and fixedly connected to the inner wall of the cylinder side, and a gas tank is fixedly connected to the outer wall of the compressed air pipe on the side away from the cylinder. The hydrogen in the cylinder is compressed and squeezed into the gas tank through the compressed air pipe for compressed storage.

[0013] Preferably, the outer wall of the top of the base is fixedly connected to the outer wall of the crankcase and the bottom of the gas tank, and the outer wall of the bottom of the exhaust pipe is fixedly connected to the inner wall of the top of the cylinder. When the internal pressure is too high due to the compression of hydrogen in the cylinder, exhaust can be carried out through the exhaust pipe.

[0014] (III) Beneficial Effects

[0015] This invention provides a circulating hydrogen compressor with an exhaust structure. It has the following advantages:

[0016] (I) The opening and closing plate, through the cooperation of the pressure spring and the extrusion plate, when the hydrogen in the cylinder is compressed and the pressure exceeds the pressure set by the pressure spring on the opening and closing plate, the high-pressure hydrogen automatically pushes the opening and closing plate to slide upward along the slide rod, opening the exhaust pipe to exhaust the gas. This can release the excessive pressure in the cylinder in a timely and effective manner, avoiding equipment damage caused by excessive pressure. At the same time, the operator can easily adjust the position of the screw rod by turning the handle, thereby precisely changing the height of the extrusion plate, and thus adjusting the pressure of the pressure spring on the opening and closing plate. This allows the exhaust device to freely set the exhaust opening pressure according to different working conditions, enhancing the practicality and versatility of the equipment.

[0017] (ii) The flow guide is connected to the exhaust pipe through the fixed frame, which can effectively guide the exhaust airflow downward, avoid the high-pressure and high-speed airflow from directly spraying onto the operator, reduce the risk of injury to personnel caused by airflow impact, and at the same time, the hydrogen will generate noise when it is discharged through the exhaust pipe, while the sound-absorbing plate on the inner wall of the flow guide can absorb some of the noise, reduce the noise pollution to the surrounding environment when the compressor is working, and help to create a relatively quiet working environment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a technical solution: a circulating hydrogen compressor with an exhaust structure, comprising: a base 1, a cylinder 2 fixedly connected to the outer wall of the top of the base 1, a crankcase 3 fixedly connected to the outer wall of the cylinder 2, and an exhaust device 6, the outer wall of the bottom of the exhaust device 6 being fixedly connected to the inner wall of the top of the cylinder 2; the exhaust device 6 includes an exhaust pipe 61, a slide rod 62 fixedly connected to the outer wall of the top of the exhaust pipe 61, a guide shroud 63 fixedly connected to the outer wall of the top of the slide rod 62, and a guide shroud 63 fixedly connected to the outer wall of the bottom of the guide shroud 63. A fixed bracket 631 is connected to the inner wall of the flow guide 63, a sound-absorbing plate 64 is fixedly connected to the inner wall of the top of the flow guide 63, a screw rod 65 is threadedly connected to the inner wall of the top of the screw rod 65, a handle 66 is fixedly connected to the outer wall of the top of the handle 65, a pressure plate 67 is rotatably connected to the outer wall of the bottom of the handle 66, a pressure spring 68 is fixedly connected to the outer wall of the bottom of the pressure plate 67, an opening and closing plate 69 is slidably connected to the outer wall of the slide rod 62, a plug 691 is fixedly connected to the outer wall of the bottom of the opening and closing plate 69, and a sealing ring 692 is fixedly connected to the outer wall of the plug 691.

[0025] The slide rods 62 are arranged in a ring around the central point of the exhaust pipe 61. The guide shroud 63 is set outside the exhaust pipe 61. The inner wall of the fixing frame 631 is fixedly connected to the outer wall of the exhaust pipe 61. The guide shroud 63, which is connected to the exhaust pipe 61 through the fixing frame 631, guides the ejected airflow downward to avoid the airflow directly spraying onto the operator.

[0026] The inner wall of the extrusion plate 67 is slidably connected to the outer wall of the slide bar 62. The outer wall of the pressure spring 68 on the side away from the extrusion plate 67 is fixedly connected to the outer wall of the top of the opening and closing plate 69. When the pressure in the cylinder 2 exceeds the pressure of the pressure spring 68 on the opening and closing plate 69, the high-pressure hydrogen will push the opening and closing plate 69 to slide upward along the slide bar 62.

[0027] The outer wall of the bottom of the opening and closing plate 69 contacts the outer wall of the top of the exhaust pipe 61, and the outer wall of the sealing ring 692 is slidably connected to the inner wall of the exhaust pipe 61. When the opening and closing plate 69 slides upward along the slide rod 62, the plug 691 will be pulled out from the exhaust pipe 61, and the sealing ring 692 will also detach from the inner wall of the exhaust pipe 61, thus opening the exhaust pipe 61.

[0028] A compressed air pipe 4 is symmetrically fixedly connected to the inner wall of the side of the cylinder 2. A gas tank 5 is fixedly connected to the outer wall of the compressed air pipe 4 away from the cylinder 2. The hydrogen in the cylinder 2 is compressed and squeezed into the gas tank 5 through the compressed air pipe 4 for compression and storage.

[0029] The outer wall of the top of the base 1 is fixedly connected to the outer wall of the crankcase 3 and the bottom of the gas tank 5. The outer wall of the bottom of the exhaust pipe 61 is fixedly connected to the inner wall of the top of the cylinder 2. When the internal pressure is too high due to the compression of hydrogen in the cylinder 2, exhaust can be carried out through the exhaust pipe 61.

[0030] During use, the base 1 provides stable support for the entire compressor, ensuring the normal operation of each component. The drive motor in the crankcase 3 drives the crankshaft to rotate. The crankshaft converts the rotational motion into the reciprocating linear motion of the piston in the cylinder 2 through the connecting rod. When the piston moves, a negative pressure is formed in the cylinder 2. Hydrogen is drawn into the cylinder 2 through the air inlet. As the piston reciprocates, the hydrogen in the cylinder 2 is compressed and squeezed into the gas tank 5 through the compressed air pipe 4 for compression and storage. When the gas pressure in the gas tank 5 reaches a certain value, the crankcase 3 stops working. To avoid the crankcase 3 not closing in time or the pressure in the cylinder 2 being too high, exhaust can be performed through the exhaust device 6.

[0031] As the hydrogen gas in cylinder 2 is compressed, when the pressure inside cylinder 2 exceeds the pressure of the pressure spring 68 on the opening and closing plate 69, the high-pressure hydrogen gas will push the opening and closing plate 69 to slide upward along the slide rod 62. At this time, the plug 691 is pulled out from the exhaust pipe 61, and the sealing ring 692 also separates from the inner wall of the exhaust pipe 61. The exhaust pipe 61 opens, and the compressed hydrogen gas is discharged through the exhaust pipe 61. At the same time, the operator can adjust the position of the screw rod 65 by turning the handle 66, thereby changing the height of the extrusion plate 67. The change in the height of the extrusion plate 67 will change the degree of compression of the pressure spring 68, thereby adjusting the pressure of the pressure spring 68 on the opening and closing plate 69. In this way, the pressure required to open the exhaust device 6 can be flexibly adjusted according to actual needs to adapt to different working conditions.

[0032] When hydrogen is discharged through the exhaust pipe 61, the guide shroud 63, which is connected to the exhaust pipe 61 by the fixing bracket 631, guides the ejected airflow downward to avoid the airflow directly spraying onto the operator. At the same time, when hydrogen is discharged through the exhaust pipe 61, it will generate some noise. The sound-absorbing plate 64 on the inner wall of the guide shroud 63 can absorb some of the noise, play a role in noise reduction, and reduce the noise impact of the compressor on the surrounding environment when it is working.
