AI Technical Summary
[0002]现有的部分药品在生产时，需要使用具有转笼的药品生产设备来对药品进行翻滚（如在药品包衣工序、药品干燥工序），而药品在转笼中翻滚时会使得药品表面的物质（如油污、角质等）会黏附在转笼表面而导致转笼表面形成残留物；尤其是在需要对药品进行干燥时，会使得转笼表面形成残留物干燥固化而难以清洗；而转笼表面的这些残留物需要定期进行清理才能保证药品的产品质量；而现有具有转笼的药品生产设备不带清洗机构，只能人工将转笼从药品生产设备上拆卸下来，然后再对转笼进行人工清洗或机器清洗，清洗完的转笼再安装回药品生产设备的机箱中，这样每次对转笼进行清洗都需要拆装转笼，操作操作繁琐且成本较高
[0015]采用上述方案后，本实用新型可以对转笼进行在线清洗；具体的，当需要对药品生产设备的转笼进行清洗时，首先，将清洗刷可转动的安装到清洗槽中；然后，打开进液阀门并通过进液阀门往清洗槽中输入清洗液；接着，控制超声波发生器进行工作，同时控制转笼进行转动；此时，超声波发生器产生的振动波会在清洗液中传播并使得清洗液中形成大量气泡，这些气泡塌缩时会产生强烈冲击力与微流效应而作用于转笼表面，从而对转笼进行超声波清洗，使得转笼表面的残留物松动脱落；于此同时，转笼会带动清洗刷转动，使得清洗刷对转笼表面进行清刷，进一步保证转笼表面的残留物能脱落；待清洗完成后，控制超声波发生器停止工作和控制转笼停止转动，并打开排液阀门排出清洗槽中的清洗液和转笼脱落的残留物，最后取出清洗刷。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical production equipment, and in particular to an online cleaning system for rotating drums. Background Technology
[0002] In some existing pharmaceutical production processes, rotating drums are used to tumble the drugs (such as in drug coating and drying processes). During this tumbling, substances from the drug's surface (such as oil and keratin) adhere to the drum, leaving residue. This residue is particularly problematic during drying, as it hardens and becomes difficult to clean. Regular cleaning is necessary to maintain product quality. However, existing rotating drum pharmaceutical production equipment lacks a cleaning mechanism. The drum must be manually removed from the equipment for manual or machine cleaning, and then reinstalled. This cumbersome and costly process requires disassembling and reassembling the drum for each cleaning.
[0003] In view of the above problems, it is necessary to study an online cleaning system for rotating drums that can directly clean the drums without disassembling them, making it convenient for users. Utility Model Content
[0004] The purpose of this invention is to provide an online cleaning system for rotating drums, which can directly clean the rotating drums without disassembling them, making it convenient for users.
[0005] To achieve the above objectives, the solution of this utility model is: An online cleaning system for a rotating drum includes a composite cleaning device installed in the chassis of a pharmaceutical production equipment. The pharmaceutical production equipment has a rotating drum rotatably disposed in the chassis. The composite cleaning device includes a cleaning tank installed in the chassis of the pharmaceutical production equipment, an ultrasonic generator installed in the cleaning tank, and a cleaning brush rotatably installed in the cleaning tank. The cleaning tank is located below the rotating drum of the pharmaceutical production equipment, and the bottom of the rotating drum is accommodated in the cleaning tank. The cleaning tank is connected to an inlet valve and an outlet valve. The cleaning brush is detachably coupled to the cleaning tank, and the cleaning brush moves against the outside of the rotating drum.

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0026] like Figures 1 to 7 As shown, this utility model discloses an online cleaning system for a rotating drum, which includes a composite cleaning device 1 installed in the casing A1 of a pharmaceutical production equipment A; the pharmaceutical production equipment A has a rotating drum A2 rotatably disposed in the casing A1; the composite cleaning device 1 includes a cleaning tank 11 installed in the casing A1 of the pharmaceutical production equipment A, an ultrasonic generator 12 installed in the cleaning tank 11, and a cleaning brush 13 rotatably installed in the cleaning tank 11; the cleaning tank 11 is located below the rotating drum A2 of the pharmaceutical production equipment A, and the bottom of the rotating drum A2 is accommodated in the cleaning tank 11; the cleaning tank 11 is connected to an inlet valve 15 and an outlet valve 16; the cleaning brush 13 is detachably coupled to the cleaning tank 11, and the cleaning brush 13 moves against the outside of the rotating drum A2; the ultrasonic generator 12 can be installed on the outside of the cleaning tank 11 to prevent water from entering the ultrasonic generator 12.
[0027] When cleaning the rotating drum A2 of pharmaceutical production equipment A is required, firstly, the cleaning brush 13 is rotatably installed into the cleaning tank 11; then, the liquid inlet valve 15 is opened and cleaning fluid is introduced into the cleaning tank 11 through the liquid inlet valve 15; next, the ultrasonic generator 12 is controlled to work, and the rotating drum A2 is controlled to rotate simultaneously; at this time, the vibration waves generated by the ultrasonic generator 12 will propagate in the cleaning fluid and cause a large number of bubbles to form in the cleaning fluid. When these bubbles collapse, they will generate a strong impact force and microfluidic effect, which will act on the... The ultrasonic cleaner cleans the surface of the rotating drum A2, loosening and removing any residue. Simultaneously, the rotating drum A2 drives the cleaning brush 13 to rotate, further cleaning the surface of the drum A2 and ensuring the residue is removed. After cleaning, the ultrasonic generator 12 stops working, the rotating drum A2 stops rotating, and the drain valve 16 is opened to drain the cleaning solution and residue from the cleaning tank 11. Finally, the cleaning brush 13 is removed.
[0028] As can be seen from the above, this utility model can perform ultrasonic cleaning and brushing of the rotating drum A2 using the composite cleaning device 1, ensuring the cleaning effect of the rotating drum A2. Furthermore, this utility model eliminates the need to disassemble the rotating drum A2 during cleaning, achieving online cleaning, making cleaning more convenient and user-friendly. The cleaning solution can be water or a solution prepared from water and a cleaning agent.
[0029] In an embodiment of this utility model, the inner wall of the cleaning tank 11 is equipped with support clamps 14 corresponding to both ends of the cleaning brush 13, and the ends of the cleaning brush 13 are rotatably inserted into the support clamps 14. This arrangement allows the cleaning brush 13 to be disassembled and assembled easily. When the rotating drum A2 needs to be cleaned, the cleaning brush 13 is installed in the cleaning tank 11; when the rotating drum A2 does not need to be cleaned, the cleaning brush 13 is removed to avoid the cleaning brush 13 affecting the production of medicines.
[0030] In an embodiment of this utility model, the composite cleaning device 1 may further include a steam coil 17 for receiving steam. The steam coil 17 is installed in the cleaning tank 11. After the steam coil 17 receives steam, it can heat the cleaning liquid in the cleaning tank 11, thereby improving the cleaning effect of the cleaning liquid on the residue on the surface of the rotating drum A2. The steam coil 17 is connected to a steam valve 18 located outside the cleaning tank 11.

As the rotating drum A2 rotates, the inner brush body 2 tumbles within the rotating drum A2 to clean the inside of the rotating drum A2, ensuring that any residue on the inside of the rotating drum A2 can be removed. After the rotating drum A2 is cleaned, the inner brush body 2 is removed to avoid affecting the production of pharmaceuticals. The inner brush body 2 may include multiple interlocking sub-brush bodies 21, so that when the inner brush body 2 is inserted into or removed from the rotating drum A2, it can be separated into multiple sub-brush bodies 21, facilitating insertion and removal operations.
[0032] In an embodiment of this utility model, the online cleaning system for a rotating drum may further include an outer brush body 3 rotatably installed inside a housing A1 of the pharmaceutical production equipment A. The outer brush body 3 is detachably fitted to the housing A1 and is located outside the cleaning tank 11. When the rotating drum A2 needs to be cleaned, the outer brush body 3 is inserted into the housing A1. When the rotating drum A2 rotates, it will drive the outer brush body 3 to rotate, allowing the outer brush body 3 to further clean the outside of the rotating drum A2, ensuring that the residue on the outside of the rotating drum A2 is removed. After the rotating drum A2 is cleaned, the inner brush body 2 is removed to avoid affecting the production of pharmaceuticals. The inner wall of the housing A1 is fitted with mounting clamps A11 at both ends corresponding to the outer brush body 3, and the ends of the outer brush body 3 are rotatably inserted into the mounting clamps A11.
