Description

Technical Field

[0001] This utility model specifically relates to a pressure vessel sight glass with a magnetic cleaning brush. Background Technology

[0002] Sight glasses for pressure vessels are used to monitor the internal conditions of containers in industries such as chemical and petroleum, but they are often obstructed by splashing media. Existing technologies, such as the sight glass observation window with a scraper flange disclosed in Chinese utility model patent "CN217332998U", clean the sight glass through a pneumatic drive device and a complex linkage system. However, this cleaning method has a complex structure, is difficult to maintain, and its cleaning effect depends on the contact between the scraper and the glass, making it prone to incomplete cleaning or damage to the glass.

[0003] To address these issues, this application proposes a pressure vessel sight glass with a magnetic cleaning brush, designed to simplify the structure and improve cleaning efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pressure vessel sight glass with a magnetic cleaning brush to address the shortcomings of the prior art. This provides a clearer and more reliable observation effect, simplifies the cleaning structure, improves cleaning efficiency, and reduces maintenance and usage costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel sight glass with a magnetic cleaning brush, comprising a flange and a transparent observation window installed inside the flange, characterized in that: it further comprises two sets of outer magnetic scrapers and inner magnetic scrapers respectively placed on the inner and outer end faces of the transparent observation window, the outer magnetic scrapers and inner magnetic scrapers being symmetrically distributed; one end of the outer magnetic scraper is located at the center of the transparent observation window and is hinged to the flange, and the other end of the outer magnetic scraper extends to the inner wall of the flange; one end of the inner magnetic scraper is located at the center of the transparent observation window and is hinged to the flange, and the other end of the inner magnetic scraper extends to the inner wall of the flange.

[0006] This technical solution employs a simpler and more efficient design. It utilizes the interaction of magnetic forces through symmetrically distributed outer and inner magnetic scrapers on both end faces to achieve the cleaning function. This simplifies the cleaning structure, eliminating complex drive mechanisms and linkage systems, and instead employing simple hinges and magnetic action. This significantly reduces the number of parts, thereby lowering maintenance difficulty and failure rates, and also reducing production costs. Secondly, the magnetic scrapers can evenly adhere to the surface of the transparent observation window, providing stable and reliable cleaning, effectively avoiding cleaning problems caused by uneven pressure or improper adjustment, thus improving cleaning efficiency and quality. In terms of response speed, the movement of the magnetic scrapers is more direct and rapid, allowing for faster start and end of the cleaning process compared to complex mechanical transmission systems.

[0007] As a further embodiment of this utility model: the flange is provided with an outer crossbeam on one side of the outer end face of the transparent observation window. The outer crossbeam is distributed along a direction parallel to the diameter of the transparent observation window. An outer hinge hole is provided in the middle of the outer crossbeam. One end of the outer magnetic scraper is connected to an outer hinge shaft. The lower end of the outer hinge shaft is connected to the end of the outer magnetic scraper, and the middle part is rotatably connected to the outer hinge hole.

[0008] By incorporating an outer crossbeam and an outer hinge hole, a rotatable connection between the outer magnetic scraper and the flange is achieved, avoiding a complex mechanical transmission mechanism. This also eliminates the need for an opening in the transparent observation window, protecting it. The non-rigid contact between the outer magnetic scraper and the observation window reduces wear and extends the service life of the sight glass.

[0009] As a further embodiment of this utility model: a swing arm is connected to the upper end of the outer hinge shaft, and a lever is connected to the end of the swing arm located away from the outer hinge shaft.

[0010] It facilitates control of the rotation of the outer hinge shaft around the outer hinge hole. By directly pushing the lever by hand or machine, the swing arm can drive the outer hinge shaft to rotate. During this process, neither the hand nor the machine will directly contact the outer hinge shaft, thus protecting it.

[0011] As a further embodiment of this utility model: the flange is provided with an inner crossbeam on one side of the inner end face of the transparent observation window. The inner crossbeam is distributed along the direction parallel to the diameter of the transparent observation window. An inner hinge hole is provided in the middle of the inner crossbeam. One end of the inner magnetic scraper is connected to an inner hinge shaft. The lower end of the inner hinge shaft is connected to the end of the inner magnetic scraper, and the middle part is rotatably connected to the inner hinge hole.

[0012] By incorporating an inner crossbeam and an inner hinge hole, a rotatable connection between the inner magnetic scraper and the flange is achieved, avoiding a complex mechanical transmission mechanism. This also eliminates the need for an opening in the transparent observation window, protecting it. The non-rigid contact between the inner magnetic scraper and the observation window reduces wear and extends the service life of the sight glass.

[0013] As a further embodiment of this utility model: the inner magnetic scraper is provided with a scraper strip on the end face near the transparent observation window.

[0014] The addition of a scraper improves the sealing and cleaning efficiency between the inner magnetic scraper and the transparent viewing window surface, ensuring more effective removal of dirt and preventing the formation of cleaning dead corners.

[0015] As a further embodiment of this utility model: the flange includes an outer flange ring and an inner flange ring arranged opposite to each other. The outer flange ring is provided with an upper annular groove at one end facing the inner flange ring, and the inner flange ring is provided with a lower annular groove corresponding to the upper annular groove. The upper annular groove and the lower annular groove cooperate with each other and limit the transparent observation window between the outer flange ring and the inner flange ring.

[0016] Designing the flange as a separate structure with interlocking outer and inner flange rings achieves several technical advantages: First, this structure simplifies the assembly process. The interlocking upper and lower annular grooves allow the transparent observation window to be quickly and accurately positioned between them, improving assembly efficiency and ensuring precision. Second, this design enhances the overall strength and stability of the pressure vessel sight glass. The mutual support between the inner and outer flange rings better withstands pressure changes and mechanical impacts, reducing the risk of leakage.

[0017] As a further embodiment of this utility model: a first sealing gasket is provided between the transparent observation window and the upper annular groove, and a second sealing gasket is provided between the transparent observation window and the lower annular groove.

[0018] The first and second sealing gaskets enhance the sealing between the transparent observation window and the flange, preventing media leakage and ensuring the safe operation of the pressure vessel.

[0024] like Figures 1 to 2 The pressure vessel sight glass with magnetic cleaning brush shown includes a flange, a transparent observation window 1 installed inside the flange, and two sets of outer magnetic scrapers 2 and inner magnetic scrapers 3 respectively placed on the inner and outer ends of the transparent observation window 1. The outer magnetic scrapers 2 and inner magnetic scrapers 3 are symmetrically distributed. One end of the outer magnetic scraper 2 is located at the center of the transparent observation window 1 and is hinged to the flange, while the other end of the outer magnetic scraper 2 extends to the inner wall of the flange. One end of the inner magnetic scraper 3 is located at the center of the transparent observation window 1 and is hinged to the flange, while the other end of the inner magnetic scraper 3 extends to the inner wall of the flange.

[0025] An outer crossbeam 4 is located on one side of the outer end face of the flange of the transparent observation window 1. The outer crossbeam 4 is distributed along a direction parallel to the diameter of the transparent observation window 1. An outer hinge hole 5 is provided in the middle of the outer crossbeam 4. One end of the outer magnetic scraper 2 is connected to an outer hinge shaft 6. The lower end of the outer hinge shaft 6 is connected to the end of the outer magnetic scraper 2, and the middle part is rotatably connected to the outer hinge hole 5. By setting the outer crossbeam 4 and the outer hinge hole 5, the rotatable connection between the outer magnetic scraper 2 and the flange is realized, avoiding a complex mechanical transmission mechanism. At the same time, it also eliminates the need for openings in the transparent observation window 1, thus protecting the transparent observation window 1. The non-rigid contact between the outer magnetic scraper 2 and the observation window reduces wear and extends the service life of the sight glass.

[0026] A swing arm 7 is connected to the upper end of the outer hinge shaft 6, and a lever 8 is connected to the end of the swing arm 7 located away from the outer hinge shaft 6. This facilitates control of the rotation of the outer hinge shaft 6 around the outer hinge hole 5. By directly pushing the lever 8 by hand or machine, the swing arm 7 can drive the outer hinge shaft 6 to rotate. During this process, neither the hand nor the machine will directly contact the outer hinge shaft 6, thus protecting the outer hinge shaft 6.

[0027] An inner crossbeam 9 is located on one side of the inner end face of the flange within the transparent observation window 1. The inner crossbeam 9 is distributed along a direction parallel to the diameter of the transparent observation window 1. An inner hinge hole 10 is located in the middle of the inner crossbeam 9. One end of the inner magnetic scraper 3 is connected to an inner hinge shaft 11. The lower end of the inner hinge shaft 11 is connected to the end of the inner magnetic scraper 3, and the middle part is rotatably connected to the inner hinge hole 10. By setting the inner crossbeam 9 and the inner hinge hole 10, a rotatable connection between the inner magnetic scraper 3 and the flange is achieved, avoiding a complex mechanical transmission mechanism. It also eliminates the need for openings in the transparent observation window 1, protecting it. The non-rigid contact between the inner magnetic scraper 3 and the observation window reduces wear and extends the service life of the sight glass.

[0028] The inner magnetic scraper 3 has a scraper strip 12 on its end face near the transparent observation window 1. The addition of the scraper strip 12 can improve the sealing and cleaning efficiency of the contact between the inner magnetic scraper 3 and the surface of the transparent observation window 1, ensuring more effective removal of dirt and preventing the formation of cleaning dead corners.

[0029] The flange includes an outer flange annular body 13 and an inner flange annular body 14 arranged opposite to each other. The outer flange annular body 13 has an upper annular groove 15 at its end facing the inner flange annular body 14, and the inner flange annular body 14 has a lower annular groove 16 corresponding to the upper annular groove 15. The upper annular groove 15 and the lower annular groove 16 cooperate to confine the transparent observation window 1 between the outer flange annular body 13 and the inner flange annular body 14. Designing the flange as a separate structure with cooperating outer flange annular bodies 13 and inner flange annular bodies 14 achieves several technical benefits: First, this structure simplifies the assembly process. Through the cooperation of the upper annular groove 15 and the lower annular groove 16, the transparent observation window 1 can be quickly and accurately positioned between them, improving assembly efficiency and ensuring assembly accuracy. Second, this design enhances the overall strength and stability of the pressure vessel sight glass. Due to the mutual support of the inner and outer flange annular bodies 13, it can better withstand pressure changes and mechanical impacts, reducing the risk of leakage.

[0030] A first sealing gasket 17 is provided between the transparent observation window 1 and the upper annular groove 15, and a second sealing gasket 18 is provided between the transparent observation window 1 and the lower annular groove 16. The first sealing gasket 17 and the second sealing gasket 18 can enhance the sealing between the transparent observation window 1 and the flange, prevent media leakage, and ensure the safe operation of the pressure vessel.

[0031] This embodiment employs a simpler and more efficient design. The cleaning function is achieved through the symmetrical distribution of outer magnetic scrapers 2 and inner magnetic scrapers 3 on both end faces, utilizing the interaction of magnetic forces. This simplifies the cleaning structure, eliminating complex drive mechanisms and linkage systems, and instead using simple hinges and magnetic action, significantly reducing the number of parts, thereby lowering maintenance difficulty and failure rate, and also reducing production costs. Secondly, the magnetic scrapers can uniformly adhere to the surface of the transparent observation window 1, providing a stable and reliable cleaning effect, effectively avoiding cleaning problems caused by uneven pressure or improper adjustment, thus improving cleaning efficiency and quality. In terms of response speed, the movement of the magnetic scrapers is more direct and rapid, allowing for faster start and end of the cleaning process compared to complex mechanical transmission systems.
