Abstract
Description
Technical Field
[0001] This application relates to the field of isolation sleeve technology, and in particular to a high-strength explosion-proof isolation sleeve. Background Technology
[0002] Magnetic stirred reactors are important pieces of equipment widely used in the fields of chemistry, pharmaceuticals, and biotechnology. Utilizing magnetic coupling technology, they achieve contactless power transmission, enabling efficient mixing and reaction of different types of substances, greatly facilitating research and production. Isolation columns are primarily used in the magnetic stirring of the reactor.
[0003] When subjected to high pressure inside the reactor, especially during pressure fluctuations or impacts, common isolation sleeves are prone to bulging, deformation, or even bursting, leading to isolation failure and causing safety accidents. Summary of the Invention
[0004] To improve the safety of the isolation sleeve, this application provides a high-strength explosion-proof isolation sleeve.
[0005] This application provides a high-strength explosion-proof isolation sleeve, which adopts the following technical solution: A high-strength explosion-proof isolation sleeve includes an outer sleeve and an inner sleeve. The front end of the outer sleeve is provided with a flange, and the wall of the outer sleeve is provided with a reinforcing structure to enhance its radial compressive strength.
[0006] By adopting the above technical solution, the outer and inner sleeves of the isolation sleeve support each other and bear pressure together, greatly resisting internal pressure. Even if the inner sleeve ruptures in an extreme manner, the outer sleeve can still temporarily maintain its integrity, providing a buffer time for system shutdown. The isolation sleeve has dual explosion-proof protection, greatly reducing production safety risks. The reinforced structure is used to enhance its radial compressive strength and improve the strength of the outer sleeve, thus improving the safety of the isolation sleeve.
[0007] Optionally, the reinforcing structure is a spirally wound reinforcing rib disposed on the outer wall of the outer jacket.
[0008] By adopting the above technical solution, the reinforcing ribs can act like a "hoop" to effectively suppress the radial expansion and deformation of the outer sleeve, thereby improving the safety of the isolation sleeve.
[0009] Optionally, a reinforcing ring block is provided at the connection between the flange and the outer casing.
[0010] By adopting the above technical solution, the stress concentration between the flange and the outer sleeve is reduced by setting the reinforcing ring block, resulting in good fatigue resistance and a more durable isolation sleeve.
[0011] Optionally, the outer casing is made of stainless steel.
[0012] By adopting the above technical solutions, stainless steel has excellent corrosion resistance, high strength, and high hardness.
[0013] Optionally, the inner sleeve is made of polyetheretherketone (PEEK).
[0014] By adopting the above technical solution, polyetheretherketone can not only withstand high temperatures of 350℃, but also has excellent corrosion resistance. In addition, polyetheretherketone has excellent electrical insulation effect, the inner sleeve will not generate cutting magnetic field lines, there is no electromagnetic eddy current, and the efficiency of magnetic stirring reactor is improved.
[0015] Optionally, the flange has a plurality of flange holes circumferentially.
[0016] By adopting the above technical solution, the vessel is connected and fixed to the magnetic stirring reactor through the flange hole.
[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. The isolation sleeve has dual explosion-proof protection, which greatly reduces production safety risks. The reinforced structure improves the radial compressive strength of the outer sleeve, thus improving the safety of the isolation sleeve. 2. Reinforcing ribs effectively suppress radial expansion and deformation of the outer sleeve, improving the safety of the isolation sleeve. 3. The reinforcing ring reduces stress concentration between the flange and the outer sleeve, making the isolation sleeve less prone to damage. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.
[0023] This application discloses a high-strength explosion-proof isolation sleeve. (Refer to...) Figure 1 , Figure 2 , Figure 3The high-strength explosion-proof isolation sleeve includes an outer sleeve 1 and an inner sleeve 2. The outer sleeve 1 is made of stainless steel, specifically grade 316L. The inner sleeve 2 is made of polyetheretherketone (PEEK). PEEK has the characteristics of high temperature resistance, corrosion resistance, and good insulation. The thickness of both the outer sleeve (1) and the inner sleeve (2) is 10-12 mm.
[0024] Reference Figure 1 , Figure 2 , Figure 3 A flange 3 is fixed to the front end of the outer casing 1, and the flange 3 has several flange holes 6 circumferentially. A reinforcing ring 5 is fixed at the connection between the flange 3 and the outer casing 1, and the reinforcing ring 5 abuts against the outer wall of both the flange 3 and the outer casing 1. The reinforcing ring 5 is used to reduce stress concentration between the outer casing 1 and the flange 3.
[0025] Reference Figure 1 , Figure 2 , Figure 3 The outer casing 1 has a reinforcing structure 4 fixed to its wall to enhance its radial compressive strength. The reinforcing structure 4 is a spirally wound reinforcing rib 41 fixed to the outer wall of the outer casing 1.
[0026] The implementation principle of a high-strength explosion-proof isolation sleeve in this application embodiment is as follows: the isolation sleeve has dual explosion-proof protection. Even if the inner sleeve 2 is extremely ruptured, the outer sleeve 1 can still temporarily maintain its integrity, providing a buffer time for system shutdown and greatly reducing production safety risks. The spirally wound reinforcing ribs 41 effectively suppress the radial expansion and deformation of the outer sleeve 1, improve the strength of the isolation sleeve, and enhance its safety. The reinforcing ring block 5 reduces the stress concentration between the flange 3 and the outer sleeve 1, making the isolation sleeve more durable.
