Description

Technical Field

[0001] This invention relates to the technical field of gas holder sealing devices, specifically a cylindrical (POC type) thin oil sealed gas holder and its sealing device. It is a cylindrical POC type thin oil sealed gas holder suitable for blast furnace / coke oven / converter gas recovery systems in iron and steel metallurgical enterprises. Background Technology

[0002] Cylindrical (POC type) thin oil sealed gas holders are the core energy storage and pressure stabilization equipment of gas recovery systems in iron and steel metallurgical enterprises. They play an important role in large-capacity gas storage, pipeline pressure stabilization, supply and demand balance, and energy conservation and emission reduction. Their sealing performance directly determines the operational safety and efficiency of the gas holder.

[0003] The existing piston oil groove sealing device of the cylindrical POC type thin oil sealed gas holder mainly uses a clamping lever to press a long strip of sealing rubber against the side plate of the gas holder, and the sealing is achieved by the oil pressure in the piston oil groove being greater than the gas storage pressure of the gas holder. The sealing rubber strip has a two-layer structure with wooden spacers in between for support. However, the gas holder is a large welded steel structure, and the side plate of the gas holder inevitably has uneven deformation problems. The sealing rubber strip is about 6000mm long, and when it is fitted with the uneven side plate, it is easy to create a large gap, which leads to serious leakage of sealing oil in the piston oil groove, significantly reduced sealing performance, and affects the normal operation of the gas holder.

[0004] There is currently no effective solution to address the aforementioned deficiencies, and there is an urgent need for a sealing component that can adapt to the concave and convex structure of the side plate, fill the fitting gap, and improve sealing performance. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this invention provides a cylindrical POC-type thin oil sealing gas holder piston oil groove sliding rubber sealing block, which is applied to the piston oil groove sealing device. The piston oil groove sealing device is installed inside the gas holder and includes sealing tape and sliding rubber sealing block. The sliding rubber sealing block is made of nitrile rubber and has a T-shaped structure. The sliding rubber sealing block integrates a spring sleeve and a compression spring. Adjacent sliding rubber sealing blocks are assembled in a T-shaped cross pattern between the upper and lower four sealing rubber tapes.

[0006] Preferably, the sliding rubber sealing block is made of nitrile rubber and molded into a T-shaped structure. A spring sleeve mounting position is preset inside the block, and the compression spring is assembled into the spring sleeve to complete the preparation of the sliding rubber sealing block.

[0007] Preferably, the piston oil groove sealing device is arranged in an orderly and tight manner along the circumference of the inner side plate of the gas holder. The force of the compression spring pushes each sliding rubber sealing block to fit tightly against the side plate of the gas holder, forming a secondary sealing structure at the uneven part of the inner side plate of the gas holder.

[0008] The beneficial effects of this invention are that the sliding sealing block is an independent elastic component that can slide freely under the action of the compression spring. It can actively adapt to the uneven structure of the gas holder side plate, effectively compensate for the gap between the sealing rubber strip and the side plate, and achieve double sealing in conjunction with the sealing rubber strip. This significantly improves the overall sealing performance of the piston oil groove sealing device, solves the problem of sealing oil leakage from the root, effectively ensures the safety and efficiency of the gas holder piston's up and down movement, maintains stable oil level and pressure in the piston oil groove, ensures the normal operation of the gas holder's core functions such as energy storage, pressure stabilization, and supply and demand balance, reduces gas venting, and improves energy utilization.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] like Figure 1-5The diagram shows a cylindrical POC-type thin oil sealed gas holder piston oil groove sliding rubber sealing block, which is applied to piston oil groove sealing device 1. Piston oil groove sealing device 1 is installed inside gas holder 2. The piston oil groove sealing device 1 includes sealing tape 6 and sliding rubber sealing block 3. The sliding rubber sealing block 3 is made of nitrile rubber and has a T-shaped structure. The sliding rubber sealing block 3 integrates a spring sleeve 4 and a compression spring 5 inside. Adjacent sliding rubber sealing blocks 3 are assembled in a T-shaped cross-shaped manner between the upper and lower four sealing rubber tapes 6.

[0014] The sliding rubber sealing block 3 can slide freely under the elastic force of the compression spring 5 and can independently adhere to the surface of the inner side plate of the gas holder 2.

[0015] The sliding rubber sealing block 3 is made of nitrile rubber and molded into a T-shaped structure. A spring sleeve 4 is preset inside it, and the compression spring 5 is assembled into the spring sleeve 4 to complete the preparation of the sliding rubber sealing block 3.

[0016] The sliding sealing block 7 is made of nitrile rubber, which has the advantages of oil resistance, wear resistance and good sealing performance, and is suitable for the working environment of the gas holder.

[0017] The piston oil groove sealing device 7 is arranged in an orderly and tight manner along the circumference of the inner side plate of the gas holder 2. The force of the compression spring 5 pushes each sliding rubber sealing block 3 to fit tightly against the side plate of the gas holder. It can actively adapt to the uneven structure of the side plate of the gas holder and form a secondary sealing structure at the uneven part of the inner side plate of the gas holder 2. This effectively makes up for the gap between the long sealing rubber strip and the side plate, and solves the problem of sealing oil leakage from the root.

[0018] Working principle: During use, the piston and piston oil groove sealing device 1 move up and down with the gas holder. When there are unevenness in the inner side plate of the gas holder 2, the sliding sealing block 3 can slide freely under the force of the compression spring 5, and adjust its position adaptively according to the uneven structure of the inner side plate, effectively making up for the gap between the sealing rubber strip 6 and the side plate.

[0019] 1. The sliding sealing block is an independent elastic component that can slide freely under the action of the compression spring. It can actively adapt to the uneven structure of the gas holder side plate, effectively compensate for the gap between the sealing rubber strip and the side plate, and achieve double sealing in conjunction with the sealing rubber strip. This significantly improves the overall sealing performance of the piston oil groove sealing device, solves the problem of sealing oil leakage from the root, effectively ensures the safety and efficiency of the gas holder piston's up and down movement, maintains stable oil level and pressure in the piston oil groove, ensures the normal operation of the gas holder's core functions such as energy storage, pressure stabilization, and supply and demand balance, reduces gas venting, and improves energy utilization.

[0020] 2. The sliding sealing block is made of nitrile rubber, which has the advantages of oil resistance, wear resistance and good sealing performance. It is suitable for the working environment of the gas holder and has a long service life.

[0021] 3. The improvement of the sealing device only requires replacing the wooden clamps and adding a spring assembly. The rest of the original components and installation methods do not need to be changed. The modification cost is low and the installation is convenient, making it suitable for upgrading existing gas holders.

[0022] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
