Fully wetted stainless steel internal floating plate wax scraping device

Abstract

This application provides a wax scraping device for a fully wetted stainless steel internal floating roof, relating to the field of internal floating roof technology for storage tanks. It includes a tank body, inside which an internal floating roof body is installed. A limiting groove is formed at the top of the internal floating roof body, and a movable ring is movably fitted inside the limiting groove. Multiple scrapers, perpendicular to the tank wall, use a layered, progressive method with annular arc-shaped scrapers to initially scrape away oil stains. The scrapers, curved and conforming to the tank wall, collect the oil stains, greatly improving the efficiency of scraping residual oil stains. By pushing a connecting rod, the connecting rod slides at the top of the limiting groove, which in turn drives the movable ring to slide within the limiting groove. The rotation of the movable ring also drives the vertical scrapers to rotate, scraping and cleaning the inner wall of the tank. This can be combined with the downward movement of the internal floating roof body for secondary cleaning, thus improving cleaning efficiency.

Description

Technical Field

[0001] This application relates to the field of floating roof technology for storage tanks, and more particularly to a wax scraping device for a fully liquid-contact stainless steel floating roof. Background Technology

[0002] The sealing system between the storage tank and the main body of the internal floating roof can be classified into mechanical seals, bladder seals, and tongue seals according to the sealing form; and into primary seals and secondary seals according to the sealing structure. The sealing system between the storage tank and the main body of the internal floating roof is the most important part of the prefabricated internal floating roof in terms of energy saving and safety.

[0003] However, with existing fully wetted stainless steel internal floating roof wax scraping devices, when the internal floating roof sinks, the oil stains on the tank wall can easily escape into the air, resulting in serious evaporation and loss. Long-term use also requires the replacement or cleaning of the scraper to avoid residues on the tank wall and scraper, which poses certain safety hazards. Utility Model Content

[0004] In view of the above problems, this application provides a fully wetted stainless steel internal floating plate wax scraping device to solve the problems of existing fully wetted stainless steel internal floating plate wax scraping devices, where oil stains on the tank wall are easily dispersed into the air when the internal floating plate sinks, resulting in serious evaporation and loss; and long-term use also requires replacement or cleaning of the scraper to avoid residues on the tank wall and scraper, which may pose certain safety hazards.

[0005] This application provides a fully liquid-contact stainless steel internal floating plate wax scraping device. It includes a tank body, inside which an internal floating plate body is installed. A limiting groove is formed at the top of the internal floating plate body, and a movable ring is movably fitted inside the limiting groove. Several vertical scrapers are installed on the outer wall of the movable ring, and a connecting rod is fixedly installed at the top of the movable ring, movably fitted inside the limiting groove.

[0006] The above solution involves pushing the connecting rod to slide at the top of the limiting groove, which in turn drives the movable ring to slide within the limiting groove. The rotation of the movable ring also drives the vertical scraper to rotate, which scrapes and cleans the inner wall of the tank. This can be combined with the downward movement of the inner floating disc body for secondary cleaning, thus improving cleaning efficiency.

[0007] In some embodiments, an annular sealing airbag is fixedly installed on the outer wall of the inner floating disk body.

[0008] By using the above method, a floating seal can be formed by filling the annular sealing airbag with gas to abut against the tank wall.

[0009] In some embodiments, a rotating shaft is movably sleeved on one side of the vertical scraper, a first bevel gear is fixedly installed on one side of the rotating shaft, a second bevel gear is symmetrically meshed with the outer wall of the first bevel gear, a screw is fixedly installed on one side of the second bevel gear, an installation block is meshed with the outer wall of the screw, and installation holes are symmetrically opened on the inner wall of the groove on one side of the movable ring.

[0010] With the above solution, the vertical scraper is movably fitted into the groove on one side of the movable ring. Turning the shaft drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate through symmetrical meshing. This drives the screw to rotate, causing the mounting block to move outward from the grooves on both sides of the vertical scraper and movably embed into the mounting hole. By turning, the vertical scraper can be easily installed and removed.

[0011] In some embodiments, a sliding groove is provided in the internal groove of one side of the vertical scraper plate, and a slider is movably sleeved inside the sliding groove. The slider is fixedly installed on the outer wall of the mounting block.

[0012] With the above solution, when the mounting block is pushed outward from the grooves on both sides of the vertical scraper, the slider also slides in the slide groove. The slider and slide groove play a limiting role, preventing the mounting block from rotating with the screw.

[0013] In some embodiments, a plurality of annular arc-shaped scrapers are fixedly installed at the bottom of the outer wall of the inner floating disk body.

[0014] The above scheme uses a layered approach with annular arc-shaped scrapers. Multiple scrapers perpendicular to the tank wall remove oil stains first, while the scrapers bent and fitted to the tank wall collect the oil stains, greatly improving the efficiency of removing residual oil stains.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Using a layered, progressive approach with annular arc-shaped scrapers, multiple scrapers perpendicular to the tank wall initially remove oil stains. The scrapers, curved and conforming to the tank wall, collect the oil stains, significantly improving the efficiency of removing residual oil. By pushing the connecting rod, it slides at the top of the limiting groove, which in turn drives the movable ring to slide within the groove. The rotation of the movable ring also drives the vertical scrapers to rotate, scraping and cleaning the inner wall of the tank. This can be combined with the downward movement of the inner floating plate for secondary cleaning, further improving cleaning efficiency.

[0017] 2. By turning the shaft, the first bevel gear is driven to rotate, and the first bevel gear drives the second bevel gear to rotate through symmetrical meshing. This drives the screw to rotate, causing the mounting block to move outward from the grooves on both sides of the vertical scraper and be inserted into the mounting hole. By turning, the vertical scraper can be easily installed and removed.

[0030] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application provides a fully liquid-contact stainless steel internal float wax scraping device. For example... Figures 1-4As shown, it includes a tank body 1, an inner floating roof body 2 is installed inside the tank body 1, a limit groove 3 is opened at the top of the inner floating roof body 2, a movable ring 4 is movably sleeved inside the limit groove 3, several vertical scrapers 5 are installed on the outer wall of the movable ring 4, and a connecting rod 6 is fixedly installed at the top of the movable ring 4, and the connecting rod 6 is movably sleeved inside the limit groove 3.

[0032] By pushing the connecting rod 6, the connecting rod 6 slides at the top of the limiting groove 3, and then drives the movable ring 4 to slide in the limiting groove 3. After the movable ring 4 rotates, it also drives the vertical scraper 5 to rotate. The rotation of the vertical scraper 5 scrapes and cleans the inner wall of the tank 1. It can be used to perform secondary cleaning when the inner floating plate body 2 moves downward to clean, which can improve the cleaning efficiency.

[0033] In the technical solution of this application embodiment, an annular sealing airbag 7 is fixedly installed on the outer wall of the inner floating disk body 2.

[0034] A floating seal can be formed by filling the annular sealing airbag 7 with gas to abut against the tank wall of the tank body 1.

[0035] In the technical solution of this application embodiment, a rotating shaft 8 is movably sleeved on one side of the vertical scraper 5, a first bevel gear 9 is fixedly installed on one side of the rotating shaft 8, a second bevel gear 10 is symmetrically meshed with the outer wall of the first bevel gear 9, a screw 11 is fixedly installed on one side of the second bevel gear 10, an installation block 12 is meshed with the outer wall of the screw 11, and installation holes 13 are symmetrically opened on the inner wall of the groove on one side of the movable ring 4.

[0036] The vertical scraper 5 is movably fitted into the groove on one side of the movable ring 4. By turning the rotating shaft 8, the first bevel gear 9 is driven to rotate. The first bevel gear 9 drives the second bevel gear 10 to rotate through symmetrical meshing, which in turn drives the screw 11 to rotate. This causes the mounting block 12 to move outward from the grooves on both sides of the vertical scraper 5 and be movably embedded into the mounting hole 13. By turning, the vertical scraper 5 can be easily installed and removed.

[0037] In the technical solution of this application embodiment, a sliding groove 14 is provided in the groove inside one side of the vertical scraper 5, and a slider 15 is movably sleeved inside the sliding groove 14. The slider 15 is fixedly installed on the outer wall of the mounting block 12.

[0038] When the mounting block 12 is pushed outward from the grooves on both sides of the vertical scraper 5, the slider 15 also slides in the slide groove 14. The slider 15 and the slide groove 14 play a limiting role, preventing the mounting block 12 from rotating with the screw 11.

[0039] In the technical solution of this application embodiment, a plurality of annular arc-shaped scrapers 16 are fixedly installed at the bottom of the outer wall of the inner floating disk body 2.

[0040] By using a layered approach with annular arc-shaped scrapers 16, multiple scrapers 16 perpendicular to the tank wall 1 can first scrape off oil stains, while the scrapers, which are curved and fit against the tank wall 1, can collect oil stains, greatly improving the scraping efficiency of residual oil stains.
