[0002] Liquefied petroleum gas is a colorless, volatile liquid obtained by pressurizing and cooling natural gas or petroleum to liquefy it in an oil refinery. It is extremely prone to spontaneous combustion, and when its content in the air reaches a certain concentration range, it can explode when exposed to open flames.

[0003] Most existing liquefied petroleum gas storage tanks are cleaned 360° by rotating the main pipe. However, due to the structural characteristics of the main pipe, connecting pipe and functional block after connection, it is destined to be able to clean only cylindrical tanks with openings at the ends. Although many liquefied petroleum gas storage tanks are also cylindrical in structure as a whole, their openings are set on the outer cylindrical wall of the tank body. In this way, it is difficult for the oil cleaning device to enter the tank body and fit the inner wall of the tank for cleaning.

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] See also Figure 1-5 As shown, in this embodiment, an oil cleaner for a liquefied petroleum gas storage tank is provided, comprising a liquefied petroleum gas storage tank body 1, a cleaning device is installed inside the liquefied petroleum gas storage tank body 1, and an oil outlet device is installed on one side of the liquefied petroleum gas storage tank body 1;

[0030] The cleaning device includes a drive motor 2, which is installed on one side of the liquefied petroleum gas storage tank body 1. The output end of the drive motor 2 is equipped with a threaded rod 10. The surface of the threaded rod 10 is threadedly engaged with a movable plate 15. One side of the movable plate 15 is rotatably engaged with a rotating plate 8. The rotating plate 8 is threadedly engaged with the threaded rod 10. One side of the rotating plate 8 is equipped with multiple cleaning scrapers 11. An annular groove 12 is provided inside the liquefied petroleum gas storage tank body 1. The cleaning scraper 11 slides with the liquefied petroleum gas storage tank body 1 through the annular groove 12. An oil outlet hole 16 is provided inside the liquefied petroleum gas storage tank body 1. The liquefied petroleum gas storage tank body 1 cooperates with the oil outlet device through the oil outlet hole 16.

[0031] The application of one aspect of this embodiment is as follows: when in use, the staff starts the driving motor 2, and the output end of the driving motor 2 rotates to drive the threaded rod 10 to rotate. When the moving block 14 is limited by the sliding groove 13, the threaded rod 10 rotates to drive the moving plate 15 to move, and the threaded rod 10 rotates to drive the rotating plate 8 to rotate, and the rotating plate 8 rotates to drive the cleaning scraper 11 to move, so that the interior of the liquefied petroleum gas storage tank body 1 can be cleaned. Under the action of the cleaning scraper 11, the oil can be cleaned through the oil outlet 16. At this time, the staff pulls the pull rod 6, and the pull rod 6 moves to drive the L-shaped moving block 19 to move. When the L-shaped moving block 19 moves in and out of the oil inlet and outlet grooves 17 When the oil is cleaned up, the staff pulls the sliding rod 7, and the spring 1 22 causes the moving block 21 and the L-shaped moving block 19 to move. When the L-shaped moving block 19 moves to the inside of the oil inlet groove 17, the staff releases the sliding rod 7, and the limiting plate 9 can be limited by the limiting plate 9. By setting the limiting block 1 23 and the limiting block 2 26, the sliding rod 7 and the pull rod 6 can be limited, and the stability of the sliding rod 7 and the pull rod 6 can be maintained during operation.

[0032] The interior of the LPG storage tank body 1 of this embodiment includes two sliding grooves 13. A movable block 14 slidably engages within each of the sliding grooves 13. The movable block 14 is fixedly connected to a movable plate 15. Rotation of the threaded rod 10 drives the movable plate 15 to move. Rotation of the threaded rod 10 drives the rotating plate 8 to rotate. Rotation of the rotating plate 8 drives the cleaning scraper 11 to move, thereby cleaning the interior of the LPG storage tank body 1.

[0033] The oil outlet device of this embodiment includes a fixed rod 4, which is installed on one side of the liquefied petroleum gas storage tank body 1. An oil inlet groove 17 is opened inside the fixed rod 4, and an L-shaped moving block 19 is slidably fitted inside the oil inlet groove 17.
