[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In actual use, due to the large internal space of pressure vessels, it takes a long time to clean the inside of the vessel when using a long-handled brush, which reduces the work efficiency of the staff.
[0023] In view of this, the present invention provides an internal wall cleaning mechanism for pressure vessels, which solves the problem that in actual use, due to the large internal space of pressure vessels, it is necessary to clean the inside of the vessel for a long time when using a long-handled brush to reach into the inside of the vessel, which leads to a decrease in the work efficiency of the staff.
[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0025] Example 1: By Figure 1-4 It is known that an internal wall cleaning mechanism for a pressure vessel includes an air bladder 1, a rotating pipe 11 installed on one side of the outer wall of the air bladder 1, an mounting plate 13 disposed below the side of the rotating pipe 11 away from the air bladder 1, and a cleaning layer 12 disposed on the outer wall of the air bladder 1. The internal wall cleaning mechanism for the pressure vessel also includes a rotating device 2, an inflation device 3, and a moving device 4. The rotating device 2 is installed on the outer wall of the rotating pipe 11; the inflation device 3 is installed at the end of the rotating pipe 11 away from the air bladder 1; and the moving device 4 is installed at the bottom of the mounting plate 13. The rotating device 2 drives the rotating pipe 11 to rotate, the inflation device 3 inflates the air bladder 1, and the moving device 4 adjusts the position of the air bladder 1.
[0026] In the specific implementation process, it is worth noting that the shape of the airbag 1 is not limited. When cleaning the inside of the container, the gas in the airbag 1 is discharged so that the rotating tube 11 can be inserted into the container. A cleaning layer 12 is provided on the outer wall of the airbag 1. The cleaning layer 12 is made of rubber and has protrusions on the outer wall. In this way, the airbag 1 can better contact the inner wall of the container under the drive of the rotating device 2 and clean the inner wall of the container. When cleaning different types of containers, the moving device 4 is used for adjustment. During the cleaning process, the airbag 1 is inflated by the inflation device 3.
[0027] Furthermore, the rotating device 2 includes a servo motor 21, a protective box 22, a drive rod 23, a drive gear 24, and a driven gear 25. The servo motor 21 is positioned above the mounting plate 13. The protective box 22 is fixedly connected to the top of the mounting plate 13 and to the outer wall of the servo motor 21, and is sleeved on the outer wall of the rotating tube 11. The drive rod 23 is rotatably connected to the inner wall of the protective box 22 via a sealed bearing, and one end extending to the outside of the protective box 22 is fixedly connected to the output end of the servo motor 21. The drive gear 24 is fixedly connected to the outer wall of the drive rod 23. The driven gear 25 is fixedly connected to the outer wall of the rotating tube 11 and meshes with the outer wall of the drive gear 24. Through the cooperation of the servo motor 21 and the drive rod 23, the drive gear 24 drives the driven gear 25 to rotate, causing the rotating tube 11 to rotate. The protective box 22 protects the drive gear 24. The model of the servo motor 21 is not limited, as long as it meets the actual usage requirements.
[0028] In the specific implementation process, it is worth noting that when the servo motor 21 drives the drive rod 23 to rotate through the meshing of the active gear 24 and the driven gear 25, the rotating tube 11 rotates, causing the airbag 1 to rotate inside the container and continue to clean the inside of the container.
[0029] Furthermore, the inflation device 3 includes a blower 31, a sleeve 32, and an installation tube 33. The blower 31 is fixedly connected to the top of the mounting plate 13, and its output end extends into the interior of the protective box 22. The sleeve 32 is rotatably connected to the outer wall of the rotating tube 11 via a sealed bearing and is connected to the output end of the blower 31. One end of the installation tube 33 is fixedly connected to the end of the rotating tube 11 away from the blower 31, and its outer wall is fixedly connected to one end of the airbag, and is connected to the airbag 1 and the rotating tube 11 respectively. Through the cooperation of the blower 31 and the sleeve 32, the gas in the installation tube 33 enters the airbag 1. The model of the blower 31 is not limited, as long as it meets the actual use requirements.
[0030] In the specific implementation process, it is worth noting that when in use, the blower 31 delivers gas into the rotating pipe 11 and through the connection of the installation pipe 33, the gas enters the air bag 1 and inflates the air bag 1, which is convenient for cleaning. Conversely, when the blower 31 is stopped, the gas in the air bag 1 is discharged, causing the air bag 1 to contract, making it convenient to remove the rotating pipe 11 from the container.
[0031] Specifically, when using the internal wall cleaning mechanism of this pressure vessel, during the cleaning of the inside of the container, the height of the rotating pipe 11 is adjusted according to the size of the container using the moving device 4. After adjustment, some water is placed inside the container, and the rotating pipe 11 is inserted inside the container. Gas is delivered into the airbag 1 through the installation pipe 33 by the blower 31, causing the airbag 1 to inflate and the cleaning layer 12 on the outer wall of the airbag 1 to contact the inner wall of the container. The servo motor 21 drives the rotating drive rod 23 to rotate. Through the meshing of the drive gear 24 and the driven gear 25, the rotating pipe 11 is driven to rotate, causing the airbag 1 to rotate inside the container. This, combined with the water, cleans the inner wall of the container. After cleaning, the blower 31 is stopped from delivering gas into the container, and the blower 31 is reversed to make the gas pressure inside the airbag 1 lower than the gas pressure inside the container, thus expelling the gas from the airbag 1 and allowing the rotating pipe 11 to be removed from the container.
[0032] Example 2: From Figure 1-4 It is known that the moving device 4 includes a moving plate 41, a mounting box 42, a mounting frame 43, and a telescopic motor 44. The moving plate 41 is located below the mounting plate 13; the mounting box 42 is fixedly connected to the top of the moving plate 41; the mounting frame 43 is fixedly connected to the bottom of the mounting plate 13 and inserted into the inner wall of the mounting box 42; the telescopic motor 44 is fixedly connected to the bottom of the inner wall of the mounting box 42, and its output end is fixedly connected to the bottom of the mounting frame 43. The moving plate 41 and the mounting box 42 drive the mounting plate 13 to move, the mounting frame 43 supports the mounting plate 13, and the telescopic motor 44 drives the mounting plate 13 to rise and fall. The telescopic motor 44 is connected to a hydraulic cylinder for control.
[0033] In the specific implementation process, it is worth noting that when cleaning different types of containers, the telescopic motor 44 is used to squeeze the mounting frame 43, causing the mounting frame 43 to drive the mounting plate 13 to rise, and the overall height of the rotating pipe 11 to move upward. This enables the rotating pipe 11 to clean different types of pressure vessels.
[0034] Furthermore, a limiting post 14 is inserted into the inner wall of the mounting bracket 43, and the bottom of the limiting post 14 is fixedly connected to the bottom of the inner wall of the mounting box 42. A fixing ring 15 is rotatably connected to the outer wall of the rotating tube 11 through a bearing. The bottom of the fixing ring 15 is fixedly connected to the top of the mounting plate 13. A ball bearing 17 is attached to the outer wall of the rotating tube 11, and a support ring 16 is movably connected to the outer wall of the ball bearing 17.
[0035] In the specific implementation process, it is worth noting that when the mounting frame 43 is raised and lowered, the limiting column 14 can ensure its stable raising and lowering, and the fixing ring 15 can support the rotating tube 11 to prevent the rotating tube 11 from being too long and breaking under the action of gravity. The support ring 16 is fixed to the flange of the container opening with bolts, and the rotating tube 11 is inserted into the container through the inside of the support ring 16. A ball bearing 17 is provided between the support ring 16 and the rotating tube 11. The ball bearing 17 reduces the friction between the rotating tube 11 and the support ring 16, and supports the rotating tube 11 under the support of the support ring 16.
[0036] Specifically, based on the above embodiments, when cleaning containers of different sizes, the telescopic motor 44 drives the mounting frame 43 to rise and fall, and the mounting plate 13 drives the rotating tube 11 to move, adjusting its height. When adjusting the height, the limiting post 14 can ensure its stable movement, and the fixing ring 15 can support the rotating tube 11, making it more convenient to clean the inner wall of the container.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
