[0025] Please refer to Figure 1-Figure 3 , a storage tank cleaning device for petrochemical industry, including a workbench 1.

[0026] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, an electric push rod 2 is arranged on the top of the workbench 1, the top rod of the electric push rod 2 is fixedly connected to the first motor 3, a cleaning component 4 is arranged under the first motor 3, moving blocks 5 are slidably arranged on both sides of the top of the workbench 1, a moving groove 6 used in conjunction with the moving block 5 is opened inside the workbench 1, a second motor 7 is fixedly connected to the top of the moving block 5, a cleaning roller 8 is fixedly connected to the output end of the second motor 7, and an adjusting component 9 for adjusting the distance between the two cleaning rollers 8 is arranged at the bottom of the workbench 1.

[0027] A placement groove 101 is provided at the bottom of the workbench 1 , and a can body 102 is placed in the placement groove 101 .

[0028] The cleaning assembly 4 includes a rotating rod 41 arranged at the output end of the first motor 3, two fixed cylinders 42 are fixedly connected to the outer side of the rotating rod 41, a fixed rod 43 is inserted into the fixed cylinder 42, a cleaning brush plate 44 is fixedly connected to one side of the fixed rod 43, the top and bottom of the fixed rod 43 are fixedly connected to the screw 45, the top and bottom of the fixed rod 43 are opened with a through groove 46 used in conjunction with the screw 45, and a knob 47 is screwed on the screw 45.

[0029] The adjustment assembly 9 includes two screw rods 91 rotatably arranged on the inner wall of the workbench 1 , a threaded block 92 is screwed on the screw rods 91 , a rotating shaft 93 is rotatably arranged inside the threaded block 92 , and the top of the rotating shaft 93 is fixedly connected to the bottom of the cleaning roller 8 .

[0030] It should be noted that: the tank body 102 to be cleaned is placed in the placement groove 101 in the workbench 1, and the spacing between the two cleaning brush plates 44 is adjusted according to the size of the tank body 102. During the adjustment, the cleaning brush plate 44 drives the fixing rod 43 to slide in the fixing cylinder 42, and the screws 45 at the top and bottom of the fixing rod 43 slide in the through groove 46, so that one side of the two cleaning brush plates 44 is close to the inner wall of the tank body 102, and then the fixing rod 43 is positioned by turning the knob 47, and then the electric push rod 2 drives the first motor 3 and the rotating rod 41 to descend to the inside of the tank body 102, and the first motor 3 drives the rotating rod 41 to rotate, so that the two cleaning brush plates 44 are close to the tank. The inner wall of the tank body 102 is cleaned, and at the same time, the electric push rod 2 drives the cleaning brush plate 44 to reciprocate up and down in the tank body 102 to evenly clean the inner wall of the tank body 102, and the threaded block 92 is driven to move by rotating the screw rod 91, so that the cleaning roller 8 on the rotating shaft 93 drives the moving block 5 to move in the moving groove 6, so that the two cleaning rollers 8 are in contact with the outer wall of the tank body 102, and the cleaning roller 8 is driven to rotate by the second motor 7 to clean the outer wall of the tank body 102, thereby achieving the effect of simultaneously cleaning the inner and outer walls of the tank bodies 102 of different sizes. During the cleaning process, a water spraying device is used to spray water on the inner and outer walls of the tank body 102 to improve the cleaning effect.

[0031] A slide groove 10 is provided inside the workbench 1 , and the outer side of the threaded block 92 is slidably matched with the inner wall of the slide groove 10 .

[0036] When in use, the tank body 102 to be cleaned is placed in the placement groove 101 in the workbench 1, and the spacing between the two cleaning brush plates 44 is adjusted according to the size of the tank body 102. During adjustment, the cleaning brush plate 44 drives the fixing rod 43 to slide in the fixing cylinder 42, and the screws 45 at the top and bottom of the fixing rod 43 slide in the through groove 46, so that one side of the two cleaning brush plates 44 is close to the inner wall of the tank body 102, and then the fixing rod 43 is positioned by turning the knob 47, and then the electric push rod 2 drives the first motor 3 and the rotating rod 41 to descend to the inside of the tank body 102, and the first motor 3 drives the rotating rod 41 to rotate, so that the two cleaning brush plates 44 touch the tank body. The inner wall of the tank body 102 is cleaned, and at the same time, the electric push rod 2 drives the cleaning brush plate 44 to reciprocate up and down in the tank body 102 to evenly clean the inner wall of the tank body 102, and the threaded block 92 is driven to move by rotating the screw rod 91, so that the cleaning roller 8 on the rotating shaft 93 drives the moving block 5 to move in the moving groove 6, so that the two cleaning rollers 8 are released from the outer wall of the tank body 102, and the cleaning roller 8 is driven to rotate by the second motor 7 to clean the outer wall of the tank body 102, thereby achieving the effect of simultaneously cleaning the inner and outer walls of the tank bodies 102 of different sizes. During the cleaning process, a water spraying device is used to spray water on the inner and outer walls of the tank body 102 to improve the cleaning effect.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
