Description

Technical Field

[0001] The utility model relates to the technical field of storage tank cleaning, in particular to a cleaning mechanism for storage tanks of multiple sizes. Background Technique

[0002] A storage tank is a container used to store liquids or gases, usually made of materials such as metals. The size, shape, and design of the storage tank depend on the substances it stores, the usage scenarios, as well as safety and environmental requirements.

[0003] Chinese patent document CN218574545U discloses a crude oil storage tank cleaning device including a bottom plate. One end of the upper surface of the bottom plate is fixedly connected with a vertical plate. The middle part of the upper surface of the bottom plate is rotatably connected with a turntable. Above the turntable, there are two arc-shaped plates, and an adjusting component for driving the two arc-shaped plates to approach or move away from each other is arranged on the turntable. By fixing the storage tank on the turntable, then the two support arms approach the side wall of the storage tank simultaneously under the elastic force of the elastic component until the cleaning roller and the scraper contact the side wall of the storage tank. The cleaning roller is driven to rotate by a first motor, and at the same time, the external water source is turned on to make water spray out from the water spray pipe onto the surface of the storage tank. The storage tank is driven to rotate horizontally by rotating the turntable, so that the cleaning roller rotates to clean the outer wall of the storage tank wetted by water. Then when the storage tank rotates to the scraper, the scraper scrapes off the water stains on the surface of the storage tank. The design of flushing, brushing, and scraping avoids water stain residue and improves the cleaning effect.

[0004] Although the above device can clean the storage tank, it cannot clean storage tanks of different sizes, and its usage is relatively limited, not meeting the actual needs. Content of the Utility Model

[0026] The present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] As Figure 1 shown, the cleaning mechanism for multi-size storage tanks includes an installation cover 1. The installation cover 1 includes a circular top plate 11 and a lower edge 12 extending downward from the outer edge of the top plate 11. A plurality of fixing assemblies 4 are provided on the inner wall of the lower edge 12. The fixing assemblies 4 are arranged in a circular array along the lower edge 12 of the installation cover 1. As Figure 4 shown, the fixing assembly 4 includes an arc-shaped plate 43 elastically connected to the inner wall of the lower edge 12 in a plane parallel to the top plate 11 and pointing in the direction of the central axis of the installation cover 1. A rubber pad is provided on the side of the arc-shaped plate 43 away from the inner edge; As Figure 2As shown in the figure, a motor 3 is fixedly installed at the center of the upper surface of the top plate 11 of the mounting cover 1 through a support sleeve 2. The output end of the motor 3 is fixedly connected to a rotating column 6 through a coupling. The rotating column 6 passes through the top plate 11 of the mounting cover 1 and is rotatably connected to the top plate 11 of the mounting cover 1. A cleaning assembly 7 is installed on the outer surface of the rotating column 6. The cleaning assembly 7 includes a cleaning roller 77 elastically connected to the rotating column 6 along the radial direction of the rotating column 6.

[0028] The fixing assembly 4 further includes a fixing block 41. The fixing block 41 is fixed to the inner wall of the lower edge 12 of the mounting cover 1. The fixing block 41 is connected to an arc plate 43 through a first spring 42. Under the elastic action of the first spring 42, the distance between the arc plate 43 and the fixing block 41 in the horizontal direction can be changed.

[0029] A liquid storage tank 5 is fixedly installed on the lower surface of the top plate 11 of the mounting cover 1. A nozzle is provided on the liquid storage tank 5.

[0030] As Figure 3 shown, the cleaning assembly 7 includes a first telescopic sleeve 71 fixedly connected to the rotating column 6. The first telescopic sleeve 71 is slidably sleeved outside a second telescopic sleeve 72. A second spring 73 is sleeved on the outer wall of the part of the second telescopic sleeve 72 extending out of the first telescopic sleeve 71. The two ends of the second spring 73 are respectively fixedly connected to one end of the first telescopic sleeve 71 close to the second telescopic sleeve 72 and one end of the second telescopic sleeve 72 far from the first telescopic sleeve 71. A support frame 74 is fixed at the front end of the second telescopic sleeve 72. A cleaning roller 77 is provided on the support frame 74. Placement grooves 75 are respectively formed at both ends of the support frame 74 corresponding to both ends of the cleaning roller 77. A cleaning roller 77 is slidably connected between the two placement grooves 75. As Figure 5 shown, central shafts 78 are provided at both ends of the cleaning roller 77. The central shafts 78 are slidably connected to the placement grooves 75. A third spring 76 is provided between one side of the central shaft 78 close to the support frame 74 and the rear side wall of the placement groove 75. The two ends of the third spring 76 are respectively connected to the central shaft 78 and the rear side wall of the placement groove 75.

[0031] Through the above settings, the cleaning roller 77 can be adjusted more flexibly with the inner wall of the tank body 9, and better fitting can be achieved. The second telescopic sleeve 72 compresses the second spring 73 inward, so that the second telescopic sleeve 72 extends more into the inner cavity of the first telescopic sleeve 71. The cleaning roller 77 compresses the third spring 76 inward, so that the cleaning roller 77 moves along the placement groove 75 towards the support frame 74.

[0032] As Figure 1 、 Figure 2As shown in the figure, it further includes a storage component 8. The storage component 8 includes a liquid storage barrel 81. The liquid storage barrel 81 is placed on one side of the mounting cover 1. A water pump 82 is fixedly installed at the center of the top of the liquid storage barrel 81. The output end of the water pump 82 is fixedly connected to a first hose 83. One end of the first hose 83 away from the water pump 82 penetrates through the mounting cover 1 and extends into the inner cavity of the liquid storage chamber 5. The input end of the water pump 82 is fixedly connected to a second hose 84. The second hose 84 penetrates through the top of the liquid storage barrel 81 and extends into the inner cavity of the liquid storage barrel 81. The second hose 84 extends to the bottom of the liquid storage barrel 81. A liquid inlet pipe is fixedly connected to the top of the liquid storage barrel 81.

[0033] The working process is as follows:

[0034] Place the mounting cover 1 at the upper opening of the tank body 9. The cleaning roller 77 is compressed inward. Through the combined action of the third spring 76 and the second spring 73, the cleaning component 7 is placed in the inner cavity of the tank body 9, and the cleaning roller 77 abuts against the inner wall of the tank body 9. At the same time, adjust the arc-shaped plate 43 to compress the first spring 42 according to the outer diameter of the tank body 9, so that the distance between it and the fixed block 41 becomes smaller, so that the rubber pad of the arc-shaped plate 43 abuts against the outer wall of the tank body 9. At this time, the first spring 42 has an inward thrust on the arc-shaped plate 43, so that the mounting cover 1 is installed on the tank body 9.

[0035] Start the water pump 82 to pump out the cleaning liquid at the bottom of the liquid storage barrel 81 through the second hose 84 and pump it into the inner cavity of the liquid storage chamber 5 through the first hose 83. Then, spray the cleaning liquid into the inner cavity of the tank body 9 through the nozzle. Then start the motor 3 to rotate the rotating column 6, driving the cleaning roller 77 of the cleaning component 7 to clean the inner wall of the tank body 9.
