Fully liquid-contact honeycomb internal floating plate wax scraper

Abstract

This application provides a fully liquid-contact honeycomb internal floating roof wax scraper, relating to the field of storage tank technology. It includes a floating roof main structure and fixed pipes. Several fixed pipes are evenly distributed and fixedly installed on the floating roof main structure. Each fixed pipe is L-shaped, and a movable rod is movably connected to its bottom end. A circular plate is fixedly connected to one end of the movable rod within the inner cavity of the fixed pipe. High-pressure gas is input into the air inlet pipe and annular pipe via an external pressurizing device. The high-pressure gas enters the fixed pipe and pushes the circular plate. The circular plate, through the movable rod, drives the arc-shaped scraper to move, allowing the scraper to be pressed firmly against the inner wall of the storage tank with a certain pre-pressure. This not only improves the fit between the scraper and the tank wall but also reduces gaps caused by scraper wear. Furthermore, the multiple staggered arc-shaped scrapers enable comprehensive and thorough wax scraping of the inner wall of the storage tank, resulting in excellent performance.

Description

Technical Field

[0001] This application relates to the field of storage tank technology, and more particularly to a fully liquid-contact honeycomb internal floating plate wax scraper. Background Technology

[0002] During the storage of crude oil, heavy oil, wax oil and other media in storage tanks, wax, colloids and impurities in the medium are prone to deposit on the inner wall of the storage tank to form a wax layer. As the storage time is extended, the wax layer gradually thickens, which not only reduces the effective volume of the storage tank, but also reduces the sealing and stability of the floating roof, aggravates the loss of oil and gas volatilization, and may even cause safety hazards.

[0003] Traditional wax scrapers typically have fixed blades, and their fit with the tank wall is greatly affected by installation precision. This can easily lead to insufficient fit due to installation issues. Furthermore, over long-term use, as the scraper blades wear down, local gaps can easily appear, which can significantly affect the wax scraping effect on the tank's inner wall and hinder a comprehensive and thorough cleaning of the tank's interior.

[0004] Based on the above reasons, this utility model proposes a fully liquid-contact honeycomb internal floating plate wax scraper, which can effectively improve the convenience of wax scraper installation and maintenance, thereby achieving thorough wax scraping of the inner wall of the storage tank and ensuring the stability of use. Utility Model Content

[0005] In view of the above problems, this application provides a fully liquid-contact honeycomb internal floating plate wax scraper to solve the problems of insufficient installation and cleaning effect of traditional wax scrapers.

[0006] This application provides a fully liquid-contact honeycomb internal floating plate wax scraper, including a floating plate main structure. Several fixed tubes are evenly distributed and fixedly installed on the floating plate main structure. The fixed tubes are L-shaped and have a movable rod movably connected to the bottom end of the fixed tube. A circular plate is fixedly connected to one end of the movable rod in the inner cavity of the fixed tube. The other end of the movable rod extends out of the fixed tube and is fixedly connected to an arc-shaped scraper. A scraping strip is installed on the arc-shaped scraper.

[0007] In some embodiments, the main structure of the floating roof includes a honeycomb structure plate, on which an oil gauging hole and a manhole are provided. Both the oil gauging hole and the manhole are covered with a cover plate. Several supporting columns are fixedly connected to the bottom surface of the honeycomb structure plate, and sealing airbags are fixedly connected to the side wall of the honeycomb structure plate.

[0008] In some embodiments, the plurality of the arc-shaped scrapers are arranged in two layers, and adjacent arc-shaped scrapers are arranged in an alternating manner.

[0009] In some embodiments, the arc-shaped scraper has an inverted L-shaped cross-section and an installation groove is provided on the horizontal side of the arc-shaped scraper. The scraper bar has a T-shaped cross-section and one side of the scraper bar is inserted into the installation groove. Several fixing bolts are evenly distributed on the top surface of the arc-shaped scraper and are threadedly connected to it. The fixing bolts pass through the scraper bar and the installation groove.

[0010] In some embodiments, the diameter of the circular plate is the same as the inner diameter of the fixed tube, and a sealing ring is fixedly connected to the outer wall of the circular plate.

[0011] In some embodiments, a fixing plate is fixedly connected to the outer wall of the fixing tube, and a crossbar is movably connected to the fixing plate. One end of the crossbar is fixedly connected to the arc-shaped scraper, and the other end of the crossbar is fixedly connected to a side plate.

[0012] In some embodiments, the top ends of several fixed tubes are fixedly connected to the same annular tube, an air inlet tube is fixedly connected to the annular tube, and a control valve is installed inside the air inlet tube.

[0013] The above solution involves injecting high-pressure gas into the inlet pipe and annular pipe via an external pressurizing device. This high-pressure gas enters the fixed pipe and pushes a circular plate. The circular plate, through a movable rod, drives the arc-shaped scraper, allowing the scraper to be pressed firmly against the inner wall of the storage tank with a certain pre-pressure. This not only improves the fit between the scraper and the tank wall but also reduces gaps caused by scraper wear. Furthermore, the multiple staggered arc-shaped scrapers enable a comprehensive and thorough waxing treatment of the tank's inner wall, resulting in excellent performance. The scraper can be removed from its mounting slot by removing the fixing bolts, and a new scraper can be inserted and the fixing bolts tightened. This allows for easy replacement of the arc-shaped scraper, simplifying maintenance and effectively reducing incomplete waxing caused by scraper wear.

[0028] 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.

[0029] like Figure 1-5 As shown, this application embodiment provides a fully liquid-contact honeycomb internal floating plate wax scraper, including a floating plate main structure 1, the floating plate main structure 1 including a honeycomb structure plate 7, the honeycomb structure plate 7 is provided with an oil measuring hole 8 and a manhole 9, both the oil measuring hole 8 and the manhole 9 are equipped with a cover plate 10, a number of support columns 11 are fixedly connected to the bottom surface of the honeycomb structure plate 7, and a sealing airbag 12 is fixedly connected to the side wall of the honeycomb structure plate 7.

[0030] In the technical solution of this embodiment, the honeycomb structure plate 7 is composed of a large number of hexagonal honeycomb units, resembling a honeycomb. The units are connected to each other to form an integral panel. The honeycomb structure plate 7 serves as the main body of the floating plate and is in direct contact with the liquid in the tank, eliminating the oil and gas space between the traditional floating plate and the liquid, thereby reducing evaporation. The manhole 9 facilitates maintenance by maintenance personnel. The oil measuring hole 8 is used to insert an oil measuring stick to measure the liquid level. The sealing airbag 12 and the cover plate 10 improve the sealing performance of the main structure 1 of the floating plate and facilitate its use.

[0031] Several fixed pipes 2 are evenly distributed and fixedly installed on the main structure 1 of the floating table. The fixed pipes 2 are L-shaped and the bottom end of the fixed pipes 2 is movably connected to a movable rod 3. One end of the movable rod 3 is fixedly connected to a circular plate 4 in the inner cavity of the fixed pipe 2. The other end of the movable rod 3 extends out of the fixed pipe 2 and is fixedly connected to an arc-shaped scraper 5. The several arc-shaped scrapers 5 are arranged in two layers and adjacent arc-shaped scrapers 5 are staggered. Scraper strips 6 are installed on the arc-shaped scrapers 5. The top ends of the several fixed pipes 2 are fixedly connected to the same annular pipe 19. An air inlet pipe 20 is fixedly connected to the annular pipe 19. A control valve 21 is installed inside the air inlet pipe 20.

[0032] In the technical solution of this embodiment, during use, the air inlet pipe 20 is connected to an external pressurizing device. The external pressurizing device is used to input high-pressure gas into the air inlet pipe 20 and the annular pipe 19. The high-pressure gas enters the fixed pipe 2 and pushes the circular plate 4. The circular plate 4 drives the arc-shaped scraper 5 to move through the movable rod 3, so that the scraper 6 can be pressed against the inner wall of the storage tank with a certain pre-pressure. This not only improves the fit between the scraper 5 and the tank wall, but also reduces the gaps caused by the wear of the scraper 6. At the same time, through multiple staggered arc-shaped scrapers 5, a comprehensive and thorough waxing treatment operation can be achieved on the inner wall of the storage tank, resulting in good performance.

[0033] Furthermore, the diameter of the circular plate 4 is the same as the inner diameter of the fixed pipe 2, and a sealing ring 15 is fixedly connected to the outer wall of the circular plate 4 to ensure the sealing between the circular plate 4 and the fixed pipe 2, thereby making the scraper 6 fit well against the inner wall of the storage tank.

[0034] Furthermore, a fixing plate 16 is fixedly connected to the outer wall of the fixing tube 2. A crossbar 17 is movably connected to the fixing plate 16. One end of the crossbar 17 is fixedly connected to the arc-shaped scraper 5, and the other end of the crossbar 17 is fixedly connected to the side plate 18. The crossbar 17 limits the arc-shaped scraper 5 laterally to ensure the stability of the arc-shaped scraper 5 in the wax scraping operation.

[0035] The cross-section of the arc-shaped scraper 5 is set in an inverted L shape, and an installation groove 13 is provided on the horizontal side of the arc-shaped scraper 5. The cross-section of the scraper 6 is set in a T shape, and one side of the scraper 6 is inserted into the installation groove 13. Several fixing bolts 14 are evenly distributed on the top surface of the arc-shaped scraper 5 and are threadedly connected. The fixing bolts 14 pass through the scraper 6 and the installation groove 13.

[0036] In the technical solution of this embodiment, when maintaining the scraper 6, the high-pressure gas inside the fixing tube 2 is discharged. At this time, by disassembling the fixing bolt 14, the scraper 6 can be taken out from the mounting groove 13, and a new scraper 6 can be inserted into the mounting groove 13 and the fixing bolt 14 can be tightened. This allows for the replacement of the scraper 6 on the arc-shaped scraper 5, which is convenient for maintenance and can effectively reduce the problem of incomplete waxing caused by the wear of the scraper 6. It is also convenient to use.
