Description

Technical Field

[0002] Vertical pressure vessels refer to pressure vessels that are set vertically, which are mainly used to store high-pressure gases or liquids, such as liquefied gas, liquid oxygen, etc. The working principle of vertical pressure vessels is mainly to use the pressure generated by the container shell on the gas medium to keep the medium within a certain pressure range. During the manufacture, installation, operation and maintenance of pressure vessels, various impurities may adhere to the outer surface, such as oil, dust, metal particles, oxides, etc. These impurities not only affect the appearance of the pressure vessel, but may also have adverse effects on the performance and service life of the equipment. Therefore, regular cleaning of the outer surface is an important measure to ensure the normal operation of the equipment.

[0003] For cleaning of vertical pressure vessels, workers are often required to hold a water pipe to spray the outer shell of the container. The vertical pressure vessel has a certain height, and the dust at a higher position is not cleaned completely. Due to height restrictions, the water pipe cannot contact the higher part of the pressure vessel well, which reduces the quality of cleaning the outer surface of the pressure vessel. In addition, it is time-consuming and energy-consuming to manually control the direction of the water pipe. The volume of the pressure vessel is also relatively large, and the overall cleaning is more labor-intensive. Therefore, it is particularly important to design a vertical pressure vessel cleaning device. Utility Model Content

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, a vertical pressure vessel cleaning device comprises a cleaning rack 1, a vertical rack 2 is arranged at the bottom of the cleaning rack 1, a servo motor 3 is arranged at the top of the cleaning rack 1, a threaded rod 4 is arranged inside the vertical rack 2, a moving block 5 is sleeved on one end of the threaded rod 4, an L-shaped plate 6 is arranged on one side of the moving block 5, a limiting ring 7 is arranged at the bottom end of the L-shaped plate 6, a plurality of positioning sleeves 15 are inserted and connected to the outer wall of the limiting ring 7, a cleaning pipe 8 is arranged inside each of the plurality of positioning sleeves 15, and an L-shaped pipe 9 is arranged at one end of each of the plurality of cleaning pipes 8. A bellows 10 is provided at one end of each of the multiple L-shaped tubes 9, and a pressure vessel body 14 is provided at the bottom of the cleaning rack 1. After the servo motor 3 is started, it will drive the threaded rod 4 to rotate synchronously, and then drive the moving block 5 to move up and down at one end of the threaded rod 4, thereby driving the limit ring 7 to move up and down, so that the cleaning range of the multiple cleaning tubes 8 on the surface of the pressure vessel body 14 can be adjusted. Since the bellows 10 is composed of foldable corrugated sheets, the bellows 10 will gradually extend and stretch after the limit ring 7 moves upward.

[0024] Embodiment 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4 As shown, one end of the multiple L-shaped tubes 9 is fixedly inserted and connected with one end of the multiple bellows 10 respectively, the diameters of the multiple bellows 10 are larger than the diameters of the multiple L-shaped tubes 9, the moving block 5 is threadedly sleeved with one end of the threaded rod 4, and the servo motor 3 is located at the top of the vertical frame 2. The utility model is a vertical pressure vessel cleaning device, which is provided with a servo motor 3, a threaded rod 4, an L-shaped plate 6 and a suction pipe 11. The moving block 5 is threadedly sleeved with one end of the threaded rod 4. During the rotation of the threaded rod 4, the outer surface of the moving block 5 is always tightly fitted with the inner wall of the vertical frame 2, so the moving block 5 can only do up and down reciprocating motion inside the vertical frame 2.

[0026] Working principle: A vertical pressure vessel refers to a pressure vessel arranged vertically, which is mainly used to store high-pressure gas or liquid. The working principle of a vertical pressure vessel is mainly to use the pressure generated by the container shell on the gas medium to keep the medium within a certain pressure range. During the manufacture, installation, operation and maintenance of the pressure vessel, various impurities such as oil, dust, metal particles and oxides may be attached to the outer surface. These impurities not only affect the appearance of the pressure vessel, but also may have adverse effects on the performance and service life of the equipment. Therefore, regular cleaning of the outer surface is an important measure to ensure the normal operation of the equipment. For the cleaning of the pressure vessel, the staff often needs to hold a water pipe to spray the outer shell of the container. The pressure vessel has a certain height, and the dust at a higher position is not cleaned comprehensively. Due to the height limit, it is not possible to achieve good contact with the higher part of the pressure vessel, which reduces the quality of cleaning the outer surface of the pressure vessel. In addition, it is time-consuming and energy-consuming to manually control the direction of the water pipe. The volume of the pressure vessel is also relatively large, and the overall cleaning is relatively labor-intensive. For this reason, since the guide pipe 13 is connected to an external water source and a water pump is installed, under the action of the water pump, water is finally transmitted to multiple cleaning pipes along the inner surface of multiple suction pipes 11. The inside of the washing pipe 8 can spray water on the outer surface of the pressure vessel body 14 to achieve the cleaning effect. After the servo motor 3 is started, it will drive the threaded rod 4 to rotate synchronously, and then drive the moving block 5 to move up and down at one end of the threaded rod 4, thereby driving the limit ring 7 to move up and down, so that the cleaning range of the surface of the pressure vessel body 14 by multiple washing pipes 8 can be adjusted. Since the bellows 10 is composed of foldable corrugated sheets, after the limit ring 7 moves upward, the bellows 10 will gradually extend and stretch, and water can continue to be transmitted to the inside of the washing pipe 8 through the L-shaped pipe 9 and the bellows 10 , increasing the cleaning area of ​​the cleaning device, the moving block 5 and one end of the threaded rod 4 are threadedly sleeved, and during the rotation of the threaded rod 4, the outer surface of the moving block 5 is always tightly fitted with the inner wall of the vertical frame 2, so the moving block 5 can only reciprocate up and down inside the vertical frame 2, and the moving block 5 and the limiting ring 7 are connected by the L-shaped plate 6. As the moving block 5 moves, the limiting ring 7 will also be driven to move at the same time, the water guide seat 12 is in contact with the ground, and one end of the suction pipe 11 is interconnected with the guide pipe 13, and the water transmitted in the guide pipe 13 will be subsequently diverted to the inside of the suction pipe 11.
