Description

Technical Field

[0001] This utility model relates to the field of chemical barrel cleaning technology, and in particular to a clamping mechanism and cleaning equipment for chemical barrels. Background Technology

[0002] Acid tank cleaning technology was developed to address the unique challenges posed by highly corrosive and hazardous chemicals. Its core focus is risk control, namely, balancing personal safety, environmental safety, equipment safety, and cleaning efficiency. Modern acid tank cleaning relies on accurate analysis of residue properties, strict management of confined space operations, flexible application and combination of various physical and chemical cleaning techniques, and efficient wastewater and waste treatment technologies. It is increasingly moving towards automation and minimally staffed or unmanned operations. This is a highly specialized and systematic engineering service.

[0003] Currently, the clamping mechanism of automated acid tank cleaning equipment only has a clamping function, holding the acid tank in place to prevent it from moving during the cleaning process. The cleaning is then achieved through the movement of a roller brush. This roller brush movement method requires reserved space for the brush's movement, resulting in a relatively large footprint for the entire automated cleaning equipment. Utility Model Content

[0008] The support frame is arranged vertically.

[0009] Multiple first rollers are mounted on one end of the bracket and in contact with the chemical barrel, thereby clamping the chemical barrel together with the first rollers of the other clamping components;

[0010] The first driving component is mounted on the bracket;

[0011] The second roller is connected to the first driving component and contacts the chemical tank; under the drive of the first driving component, the second roller rotates, thereby driving the chemical tank to rotate.

[0013] A second drive unit, mounted on the frame and connected to the sleeve, is configured to controllably drive the sleeve to move vertically relative to the frame, thereby causing the first roller to drive the chemical tank to move vertically.

[0014] Optionally, each of the clamping components further includes:

[0015] A third drive unit is mounted on the bracket and configured to controllably drive the first drive unit and the second roller to move horizontally, such that the second roller contacts or separates from the chemical tank.

[0016] Optionally, the frame includes two parallel and interconnected first vertical sections;

[0017] Each of the sleeves includes two second vertical sections and two horizontal sections, each second vertical section being fitted onto a first vertical section, and the two second vertical sections being parallel and connected to each other; each horizontal section extends horizontally from a second vertical section and is fitted with a first roller at its end.

[0018] Optionally, each of the clamping components further includes:

[0019] Multiple elastic elements are provided, with at least one elastic element installed inside each of the horizontal sections, and the first roller is installed at the end of the elastic element; when the first roller is compressed, the elastic element can drive the first roller to contract along the horizontal direction.

[0020] Optionally, the sleeve includes a first sleeve and a second sleeve, the first sleeve is arranged above the second sleeve, the second driving member is connected to the first sleeve, and the third driving member is mounted on the second sleeve and connected to the second driving member, so that the second driving member drives the first sleeve and the second sleeve to move synchronously in the vertical direction.

[0021] Optionally, the second driving element is a motor and has an output shaft connected to the first sleeve; each of the clamping assemblies further includes:

[0022] A fourth driving component is connected to the first sleeve and the third driving component, and the fourth driving component is configured to controllably drive the third driving component, the first driving component, the second roller and the second sleeve to move vertically.

[0023] Optionally, the plurality of said transverse portions are arranged in parallel and have the same extension length.

[0024] Optionally, the second roller is located at the middle position of the plurality of first rollers.

[0025] In particular, this utility model also provides a cleaning device for chemical barrels, including the above-mentioned clamping mechanism.

[0026] The clamping mechanism of this utility model includes multiple clamping components located around the periphery of the chemical tank. Each clamping component includes a support, multiple first rollers, a first driving member, and a second roller. The multiple first rollers are mounted on one end of the support and contact the chemical tank, thus clamping the chemical tank together with the first rollers of the other clamping components. The first driving member is mounted on the support, and the second rollers are connected to the first driving member and contact the chemical tank. Driven by the first driving member, the second rollers rotate, thereby causing the chemical tank to rotate.

[0027] Furthermore, the clamping assembly of this utility model also includes multiple elastic elements, with at least one elastic element installed inside each horizontal section, and a first roller mounted at the end of the elastic element. When the first roller is compressed, the elastic element can drive the first roller to contract in the horizontal direction. The above technical solution, through the design of the elastic elements, is equivalent to designing the first roller to be movable in the horizontal direction, avoiding hard contact between the first roller and the chemical drum, thus preventing scratches on the chemical drum.

[0040] Figure 1 This is a schematic structural diagram of a cleaning device 1000 according to an embodiment of the present invention. Figure 2 This is a schematic structural diagram of a clamping assembly 100 according to an embodiment of the present invention. Figure 3 This is a schematic side view of a clamping assembly 100 according to an embodiment of the present invention. Figures 1 to 3 As shown, in some embodiments, the clamping mechanism of the chemical container 200 includes multiple clamping assemblies 100 located around the periphery of the chemical container 200. Each clamping assembly 100 includes a bracket 10, multiple first rollers 20, a first drive member 60, and a second roller 70. The bracket 10 is arranged vertically. The multiple first rollers 20 are mounted on one end of the bracket 10 and contact the chemical container 200, thereby clamping the chemical container 200 together with the first rollers 200 of the other clamping assemblies 100. The first drive member 60 is mounted on the bracket 10. The second roller 70 is connected to the first drive member 60 and contacts the chemical container 200. Driven by the first drive member 60, the second roller 70 rotates, thereby causing the chemical container 200 to rotate. Here, when the second roller 70 causes the chemical container 200 to rotate, the first rollers 20 also rotate synchronously.

[0041] The clamping mechanism in this embodiment not only has a clamping function, but also has the function of driving the chemical tank 200 to rotate. It can achieve all-round cleaning of the chemical tank 200 without the need for the roller brush to move, which can reduce the space occupied by the cleaning equipment 1000 and make the structure of the cleaning equipment 1000 more compact.

[0042] In some embodiments, the first drive member 60 is a motor, and the second roller 70 is mounted on the output shaft of the motor.

[0043] In some embodiments, the support 10 includes a frame 11 and at least one sleeve, the sleeve being fitted onto the frame 11, and a first roller 20 mounted on the sleeve. Each clamping assembly 100 further includes a second drive member 30, mounted on the frame 11 and connected to the sleeve, the second drive member 30 being configured to controllably drive the sleeve to move vertically relative to the frame 11, thereby causing the first roller 20 to drive the chemical tank 200 to move vertically. Here, the chemical tank 200 is first clamped using the first roller 20 and the second roller 70, and then the second drive member 30 controllably drives the sleeve to move upward, thereby driving the chemical tank 200 upward, so that the roller brush can extend under the chemical tank 200 for cleaning.

[0044] In some embodiments, each clamping assembly 100 further includes a third drive member 40, which is mounted on the bracket 10 and configured to controllably drive the first drive member 60 and the second roller 70 to move horizontally, such that the second roller 70 contacts or separates from the chemical tank 200. Here, configuring the first drive member 60 and the second roller 70 to be horizontally movable can meet the clamping requirements of chemical tanks 200 of different diameters. In this embodiment, the third drive member 40 is a cylinder. In other embodiments, the third drive member 40 may be other drive components.

[0045] In some embodiments, the frame 11 includes two parallel and interconnected first vertical sections 111. Each sleeve includes two second vertical sections 122 and two horizontal sections 121. Each second vertical section 122 is fitted onto one first vertical section 111, and the two second vertical sections 122 are parallel and interconnected. Each horizontal section 121 extends horizontally from one second vertical section 122, and a first roller 20 is mounted at its end. This embodiment, by providing two first vertical sections 111 and two second vertical sections 122, can improve the stability of the clamping assembly 100, and by arranging multiple first rollers 20 separately, different parts of the chemical container 200 can be clamped, thereby improving the stability of clamping the chemical container 200.

[0046] In some embodiments, each clamping assembly 100 further includes a plurality of elastic elements, with at least one elastic element installed inside each transverse portion 121, and a first roller 20 mounted at the end of the elastic element. When the first roller 20 is compressed, the elastic element can cause the first roller 20 to contract in the horizontal direction.

[0047] This embodiment, through the design of an elastic element, effectively makes the first roller 20 movable in the horizontal direction, avoiding hard contact between the first roller 20 and the chemical container 200, which could scratch the chemical container 200. Furthermore, it can meet the clamping requirements of chemical containers 200 of different diameters, and the position of the first roller 20 can be adjusted according to the diameter of the chemical container 200.

[0048] In some embodiments, the sleeve includes a first sleeve 12 and a second sleeve 13. The first sleeve 12 is arranged above the second sleeve 13. A second driving member 30 is connected to the first sleeve 12. A third driving member 40 is mounted on the second sleeve 13 and connected to the second driving member 30, so that the second driving member 30 drives the first sleeve 12 and the second sleeve 13 to move synchronously in the vertical direction.

[0049] In some embodiments, the second drive member 30 is a motor with an output shaft connected to the first sleeve 12. Each clamping assembly 100 also includes a fourth drive member 50 connected to the first sleeve 12 and the third drive member 40. The fourth drive member 50 is configured to controllably drive the third drive member 40, the first drive member 60, the second roller 70, and the second sleeve 13 to move vertically. This can be understood as the fourth drive member 50 driving the second roller 70 to move and adjusting its vertical position. Essentially, the second drive member 30 can coarsely adjust the position of the second roller 70, while the fourth drive member 50 can finely adjust its position. Furthermore, the fourth drive member 50 can also drive the second sleeve 13 to move and adjust the vertical position of the first roller 20 on the second sleeve 13, thereby adjusting the distance between the first roller 20 on the second sleeve 13 and the first roller 20 on the first sleeve 12, thus meeting the clamping requirements of chemical barrels 200 of different heights.

[0050] In some embodiments, the plurality of horizontal portions 121 are arranged in parallel and have the same length. In other embodiments, the length of the plurality of horizontal portions 121 can be determined according to specific design requirements.

[0051] In some embodiments, the second roller 70 is located at the middle position of the plurality of first rollers 20. It can be understood that the second roller 70 contacts the middle position of the chemical tank 200, and the plurality of first rollers 20 disperse to clamp the upper and lower positions of the chemical tank 200, thereby improving the stability of clamping the chemical tank 200.

[0052] This embodiment also provides a cleaning device 1000 for a chemical tank 200, the cleaning device 1000 including any of the clamping mechanisms described above. Details of the clamping mechanisms are omitted here.

[0053] In this embodiment, the chemical drum 200 is first held between the first roller 20 and the second roller 70. Then, the second drive member 30 controls the upward movement of the chemical drum 200. Next, the first drive member 60 drives the second roller 70 to rotate, thus rotating the chemical drum 200. Finally, the roller brush approaches the chemical drum to clean it. After cleaning, the roller brush moves away from the chemical drum 200, the first drive member 60 stops driving the second roller 70, and then the second drive member 30 moves the chemical drum 200 downward back to its original position. If the chemical drum 200 is transported via a conveyor, it is placed back onto the conveyor so that it can be transported outside the cleaning equipment 1000.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
