Description

Technical Field

[0001] This utility model relates to the field of boiler vibrating sleeves, and more specifically, to a sealing device for boiler vibrating sleeves. Background Technology

[0002] Boiler rapping sleeves are an important component of boiler systems. They are mainly used to remove ash and deposits from the boiler's heating surfaces to ensure efficient and stable operation. Sealing devices are crucial for ensuring stable boiler system operation and extending equipment lifespan. Through precise design and the selection of high-quality materials, sealing devices can provide reliable sealing effects in extreme working environments, such as high temperature, high pressure, and the presence of corrosive media. This effectively prevents media leakage and ash accumulation, ensuring a tight connection and smooth operation between the rapping sleeve and the rapping rod. This improves the boiler's heat exchange efficiency and cleaning and maintenance performance, providing a solid guarantee for the safe and efficient operation of the boiler system.

[0003] Currently widely used rapping sleeve sealing devices mainly rely on packing to seal the tiny gaps between the sleeve and the rapping rod, supplemented by an external rubber sleeve for secondary sealing. However, this sealing method has significant limitations, especially after long-term operation. The packing material often experiences a decline in sealing performance due to wear and aging, leading to incomplete sealing and an increased risk of media leakage. Simultaneously, the original rubber sleeve sealing design is prone to slippage due to vibration and temperature changes, further exacerbating the risk of seal failure. Furthermore, the tiny gaps between the sleeve and the rapping rod can become clogged due to dust accumulation and rust, severely hindering the normal operation efficiency of the rapping device, increasing maintenance costs, and potentially adversely affecting the overall performance of the boiler system.

[0004] Therefore, we have made improvements to this by proposing a sealing device for a boiler rapping sleeve. Utility Model Content

[0029] To address the technical problems in the background section, the following sealing device for boiler rapping sleeves is provided:

[0030] Combination Figure 1 - Figure 4 As shown, the present invention provides a sealing device for a boiler rapping sleeve, including a rapping sleeve 1, a rapping rod 2 connected inside the rapping sleeve 1, and a sealing sleeve 3 sleeved on the outside of the rapping sleeve 1 and the rapping rod 2. The two ends of the sealing sleeve 3 are respectively matched with the rapping sleeve 1 and the rapping rod 2, and the inner diameters of the two ends of the sealing sleeve 3 are (110*φ100) mm and (25*φ60) mm, respectively. The thickness of the sealing sleeve 3 is 5 mm.

[0031] In this embodiment, the sealing sleeve 3 is sleeved on the outside of the vibrating sleeve 1 and the vibrating rod 2. The two ends of the sealing sleeve 3 are matched with the dimensions of the vibrating sleeve 1 and the vibrating rod 2, respectively, with inner diameters of (110φ100) mm and (25φ60) mm, respectively, to meet the sealing requirements of different parts. The thickness of the sealing sleeve 3 is designed to be 5 mm, ensuring good sealing effect and structural strength.

[0032] As a preferred embodiment, based on the above method, the sealing sleeve 3 further includes a base layer 301, and the outer side of the base layer 301 is provided with a high temperature resistant layer 302, a wear resistant layer 303, a corrosion resistant layer 304 and an elastic sealing layer 305 in sequence.

[0033] In this embodiment, the base layer 301 provides basic structural support and sealing performance. Furthermore, a high-temperature resistant layer 302, a wear-resistant layer 303, a corrosion-resistant layer 304, and an elastic sealing layer 305 are sequentially arranged on the outer side of the base layer 301. This multi-layer structure design not only significantly improves the overall performance of the sealing sleeve 3, enabling it to better adapt to harsh working environments such as high temperature, wear, and corrosion, but also ensures the stability and reliability of the sealing sleeve 3 in long-term operation through the synergistic effect between the layers.

[0034] As a preferred embodiment, based on the above method, the base layer 301 is further made of natural rubber material to ensure good elasticity, strength and wear resistance of the sealing sleeve 3.

[0035] In this embodiment: Natural rubber material has excellent elasticity, high strength and good wear resistance. By using natural rubber as the material of base layer 301, it is ensured that the sealing sleeve 3 can maintain a stable sealing effect under various complex working conditions, and can withstand certain mechanical stress and wear, thereby extending the service life of the sealing sleeve 3.

[0036] As a preferred embodiment, based on the above method, the high-temperature resistant layer 302 is further made of silicone rubber material to effectively resist thermal deformation and aging under high-temperature environment, and ensure the stability and durability of the sealing sleeve 3 under high-temperature operating conditions.

[0037] In this embodiment: In order to ensure that the sealing sleeve 3 can maintain stability and durability under high temperature operating conditions, silicone rubber material is used to make the high temperature resistant layer 302. Silicone rubber material is known for its excellent high temperature resistance, excellent thermal stability and anti-aging ability, and can effectively resist thermal deformation and aging under extreme high temperature environment. This choice not only improves the sealing performance of the sealing sleeve 3 under high temperature conditions, but also ensures its reliability and durability in long-term high temperature operation.

[0038] As a preferred embodiment, based on the above method, the wear-resistant layer 303 is further made of nitrile rubber material to improve the durability and service life of the sealing sleeve 3 under friction and wear conditions.

[0039] In this embodiment: In order to improve the durability and service life of the sealing sleeve 3 under friction and wear conditions, nitrile rubber is used to make the wear-resistant layer 303. Nitrile rubber is widely praised for its excellent wear resistance, high strength and good tear resistance. It can maintain excellent performance in various friction and wear environments. By using nitrile rubber, we ensure that the sealing sleeve 3 can still maintain a stable sealing effect under frequent friction and wear conditions, effectively extending its service life.

[0040] As a preferred embodiment, based on the above method, the corrosion-resistant layer 304 is further made of neoprene rubber to enhance the sealing sleeve 3's resistance to chemical substances and protect it from corrosive media such as acids, alkalis, and salts.

[0041] In this embodiment: In order to improve the resistance of the sealing sleeve 3 to chemical substances and ensure that it remains intact when in contact with corrosive media such as acids, alkalis, and salts, a chloroprene rubber material is used to make the corrosion-resistant layer 304. Chloroprene rubber is known for its excellent corrosion resistance, aging resistance, and good elasticity, and can maintain stable performance in a variety of corrosive environments. By using chloroprene rubber material, a strong protective barrier is provided for the sealing sleeve 3, which effectively prevents the corrosion of corrosive media, thereby ensuring the long-term stability and reliability of the sealing sleeve 3 in harsh working environments.

[0042] As a preferred embodiment, based on the above method, the elastic sealing layer 305 is further made of EPDM rubber material to ensure that the sealing sleeve 3 has excellent elastic recovery ability and sealing performance.

[0043] In this embodiment: In order for the sealing sleeve 3 to have excellent elastic recovery ability and sealing performance, EPDM rubber is used to make the elastic sealing layer 305. EPDM rubber is known for its excellent elasticity, weather resistance, ozone resistance and chemical media resistance, and can maintain a stable sealing effect under various complex working conditions. By using EPDM rubber, it can be ensured that the sealing sleeve 3 can still quickly restore its original shape when subjected to pressure, temperature changes and chemical media, thereby maintaining an effective seal.
