Description

Technical Field

[0001] The present invention relates to the technical field of mechanical seals for new energy generator sets, and in particular to a novel foil sealing device suitable for shaft end sealing of hydrogen energy generator sets. Background Art

[0002] Hydrogen power generation is considered to be one of the important directions for clean energy generation in the future. The basic principle of hydrogen power generation is to use hydrogen and oxygen to react chemically under the action of a catalyst to produce electricity and water. This process occurs in a fuel cell, where hydrogen is oxidized under the action of an anode catalyst to produce electrons and protons. Oxygen is reduced under the action of a cathode catalyst and combines with electrons and protons to produce water. The electrical energy is transmitted in an external circuit for use by the equipment. Hydrogen power generation has the characteristics of high efficiency, cleanliness, safety, and durability, and can be widely used in transportation, portable power supplies, fixed power generation and other fields. However, due to the small size and high permeability of hydrogen molecules, leakage is prone to occur at the shaft end of a high-speed rotating generator set, and the poor sealing effect of the shaft end will lead to energy loss and safety hazards.

[0003] Therefore, the present invention proposes a new foil sealing device suitable for the shaft end sealing of hydrogen energy generator sets, which can effectively prevent hydrogen leakage and improve the sealing effect and durability. The research and development and promotion and application of this technology will further promote the development of hydrogen energy power generation technology, promote the utilization of sustainable energy and environmental protection. Summary of the invention

[0004] The present invention provides a novel foil sealing device suitable for the shaft end sealing of a hydrogen energy generator set. One of the technical problems to be solved is that the shaft end sealing effect of the existing hydrogen energy generator set is poor, resulting in leakage of hydrogen energy, which not only greatly reduces the power generation efficiency of the whole machine, but also poses a certain threat to the environment.

[0005] The present invention is achieved through the following technical solutions: In view of the problem that the shaft end sealing effect of the existing hydrogen energy generator set is poor and hydrogen energy leakage is easy to occur, the present invention proposes a new foil sealing device suitable for the shaft end sealing of the hydrogen energy generator set. The hydrogen energy generator set includes a rotating shaft, and the foil sealing device includes a sealing cavity sleeved on the rotating shaft, a clamping end cover sleeved on the rotating shaft to clamp the middle sealing cavity, an elastic gasket cushioned between the sealing cavity and the clamping end cover, a foil sealing group sleeved on the rotating shaft and embedded between the sealing cavity and the rotating shaft, and an auxiliary sealing group sleeved on the rotating shaft between the clamping end cover and the sealing cavity, wherein the auxiliary sealing group and the sealing cavity are detachably connected by screws. The structure and performance of the sealing cavity, the clamping end cover, and the elastic gasket are the existing technologies that those skilled in the art should understand, and the shaft end hydrogen achieves a low leakage effect under the coordinated cooperation of the foil sealing group and the auxiliary sealing group.

[0006] Furthermore, the foil sealing group is mainly composed of a bottom flat foil, a second layer of corrugated foil, a transition flat foil and a top layer of corrugated foil, which are sequentially covered from the inside to the outside. The bottom flat foil, the second layer of corrugated foil, the transition flat foil and the top layer of corrugated foil are non-closed cylindrical structures, a card seam is provided along the axial direction, and a radially outward protrusion is provided along the card seam direction. The protrusion is adjacent to the card seam, and the bottom flat foil, the second layer of corrugated foil, the transition flat foil and the top layer of corrugated foil are mutually engaged by the protrusions and buckled together layer by layer. Each component is fixedly matched with each other, and the main sealing function of the device is realized by different deformations. The foil sealing group is fixed by the groove or protrusion structure provided to prevent loosening, interference and other undesirable phenomena during the working process, thereby ensuring the sealing performance of the device.

[0007] Furthermore, the protrusion of the bottom flat foil is in a straight line shape, and an L-shaped slot is formed on the protrusion of the second corrugated foil, and the protrusion of the bottom flat foil is inserted into the L-shaped slot for matching connection.

[0008] Furthermore, the protrusion of the transition flat foil is generally in a straight line shape, and an embedded groove is provided inside, and the protrusions of the two-layer corrugated foil are inserted into the embedded groove for matching connection.

[0009] Furthermore, the protrusion of the top corrugated foil is in the shape of a letter "┐", and is provided with a vertical groove that is matched and connected with the transition flat foil, so as to realize the axial fixation of the sealing assembly and facilitate installation and disassembly in the radial direction.

[0010] Furthermore, micron-level grooves are evenly arranged in the circumferential direction on the inner ring side of the bottom flat foil. The groove form is not specified, and can be a straight groove, a spiral groove, a herringbone groove, etc.

[0011] Furthermore, the shape of the two-layer corrugated foil is a plurality of concave fan-shaped parts connected end to end to form an integrated structure, the card seam and the protrusion are arranged on one of the concave fan-shaped parts, and the two-layer corrugated foil is provided with Lello triangular holes and elliptical holes at equal intervals along the axial direction, and the Lello triangular holes and the elliptical holes are arranged at intervals and cross-arranged, and except for the card seam and the protrusion, the other concave fan-shaped parts are discontinuous structures, and a certain amount of their surfaces are cut circumferentially along the axial direction.

[0012] Furthermore, the shape of the top layer of corrugated foil is a plurality of concave fan-shaped parts connected end to end to form an integrated structure, the snap joint and the protrusion are arranged on one of the concave fan-shaped parts, and elliptical holes are opened on the top layer of corrugated foil at equal intervals along the axial direction. Except for the snap joints and the protrusions, the other concave fan-shaped parts are discontinuous structures, and a certain amount of cutting is performed on the surface along the circumferential direction along the axial direction.

[0013] Furthermore, the auxiliary sealing group is mainly composed of multiple layers of circumferential fingertip sealing sheets, the inner diameter of which is the same as that of the bottom flat foil, and the surface of which is provided with staggered groove gaps along the circumferential direction, the groove gaps being composed of a combination of curves and straight lines, but the number and size of the groove gaps are different, so as to achieve staggered arrangement. The circumferential fingertip sealing sheets are fixedly matched with each other to achieve the function of auxiliary sealing, further reducing the leakage of hydrogen from the shaft end. In addition, its inner diameter is the same as that of the bottom flat foil and the contact surface fits tightly, blocking the leakage of hydrogen along the shaft end and forcing it to flow along the opened groove gaps, but due to the staggered arrangement of the multiple layers of circumferential fingertip sealing sheets, the circumferential leakage of the gas is blocked again, minimizing the leakage of the gas from the shaft end.

[0014] Furthermore, a groove is provided on the inner ring side of the sealing cavity along the axial direction, and the protrusion of the top layer of the corrugated foil is inserted into the groove for fitting connection.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. The sealing device can effectively prevent the leakage of hydrogen and improve the sealing effect and durability, and has the characteristics of simple structure, convenient operation, reliable operation, etc.

[0016] 2. Each foil is formed by bending a thin and soft metal sheet, which ensures the strength of the structure and provides sealing and isolation of the lower foil.

[0017] 3. The bottom flat foil is provided with several micron-sized grooves on the circumferential side of the inner ring. When the rotating shaft rotates, the dynamic pressure effect and wedge effect generated by the micro-grooves form a micron-sized rigid air film between the rotating shaft and the grooves, which increases the original shaft end sealing effect.

[0018] 4. The cross-section of each corrugated foil is in the form of an arch. By utilizing its special geometric shape and stress characteristics, it can effectively disperse and bear external loads, providing stable and reliable structural support. By cutting a certain amount of its surface along the circumferential direction, when subjected to stress, each corrugated foil will not only undergo axial deformation, but also produce a certain degree of axial deformation, thereby achieving sealing performance under multiple degrees of freedom.

[0019] 5. Adding elastic gaskets between the cavity and the end cover connectors not only provides a reliable sealing effect, but also has buffering and shock-absorbing effects, providing important guarantees for the normal operation and reliability of the device.

[0020] 6. Each component is detachable to facilitate replacement of damaged foil or cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
