[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] Example 1

[0035] Please refer to Figure 1-3 A novel centrifuge drum washer includes a mobile cleaning frame 1 and a cleaning chamber 2, which are assembled and disassembled. The mobile cleaning frame 1 includes a frame 11, a lifting portion 12 disposed on the frame 11 for lifting heavy objects, a pulley 13, and a first water baffle 14. The cleaning chamber 2 includes a chamber body 21 that can be combined with the frame 11 to form a complete closed space, a liquid inlet channel 22, at least one rotating nozzle 23, a second water baffle 24, and a collection tank 25. The rotating nozzle 23 is disposed at the water outlet end of the liquid inlet channel 22.

[0036] Through the above structural design, the frame 11 is used to provide a fixed space for the lifting part 12, the first water baffle 14, the handlebar 17 and the storage rack 15. The bottom of the frame 11 is equipped with a pulley 13 for sliding. One side of the chamber body 21 can be combined with the mobile cleaning rack 1 to form an internal space for cleaning the components of the centrifuge drum after it is disassembled. The liquid inlet channel 22 is used to supply the pressurized medium with an external pressurized medium pipeline or a delivery pump. The outlet end of the liquid inlet channel 22 is divided into two upper and lower outlet ends. The rotary nozzle 23 is connected to the outlet end. The pressurized medium is discharged to the centrifuge drum through the rotatable multi-outlet rotary nozzle 23 arranged up and down in the cleaning chamber 2. After disassembling, the centrifuge drum is disassembled into its components according to their shape, size, and cleaning difficulty. The components (such as the drum cover, bell jar, and trivet) are then placed on the hook 121 of the mobile cleaning rack and pushed into the cleaning chamber 2, forming a closed space. The cleaning chamber 2 is equipped with two upper and lower rotatable rotary nozzles 23 with multiple water outlets (i.e., each rotary nozzle 23 has multiple nozzles). The cleaning water can fully cover the disassembled components of the centrifuge drum, ensuring that there are no blind spots and the cleaning effect meets the requirements of pharmaceutical production, reducing the manpower input and the amount of injection water consumed during the cleaning process. The cleaning device is not limited to cleaning centrifuge drum components, but can also be used to clean other larger and heavier production tools, reducing the amount of cleaning water used and significantly improving the cleaning effect. It also reduces the labor input during the tool cleaning process.

[0037] Through the above-described structural design, a rotating nozzle 23 is connected to the outlet end. Pressurized medium cleans the disassembled components of the centrifuge drum through the rotatable, multi-outlet rotating nozzle 23, which is arranged vertically within the cleaning chamber 2. Considering the difficult and easy-to-clean surfaces of the cleaned device, the nozzle head and the rotating nozzle are angled. Some are vertically positioned, while others are tilted at approximately 45°, but the actual angle is adjustable. It should be noted that the rotating nozzle rotates under the action of water pressure and the reaction force of the high-pressure water spray. This is a prior art method and will not be described in detail here.

[0038] Specifically, the movable cleaning rack 1 is pushed into one side of the cleaning chamber 2 , and the first water baffle 14 and the second water baffle 24 can be closely connected on one side.

[0039] Through the above structural design, the first water baffle 14 and the second water baffle 24 are used to shield the hollow side of the chamber body 21 so that the water output by the rotary nozzle 23 will not spill out.

[0040] Specifically, the side of the mobile cleaning rack 1 is provided with an inward folding edge, and embedded positioning cards are provided on both sides below it.

[0041] Through the above structural design, the side of the cleaning rack is designed with an inward folding edge, and embedded positioning cards are designed on both sides of the bottom to ensure the airtightness of the space when the cleaning rack and the cleaning chamber 2 are combined, avoiding leakage of the medium during the cleaning process. The cleaning medium can be discharged through the discharge port 26 of the recovery tank at the bottom of the cleaning chamber 2.

[0042] Example 2

[0043] The novel centrifuge drum cleaner provided in Example 1 is further optimized, specifically, as Figure 1-3 As shown, the lifting portion 12 includes a hook 121 arranged on the top of the frame 11, and a conversion ring 122 is suspended on the hook 121.

[0044] Specifically, the conversion ring 122 is a three-ring buckle.

[0045] Through the above structural design, there is a hook 121 above the mobile cleaning rack. Through the three-ring suspension design, the heavy components of the centrifuge drum after disassembly, such as the drum cover, bell cover and three-leaf plate, can be quickly transferred from the elevator to the hook 121 of the mobile cleaning rack.

[0046] Example 3

[0047] The novel centrifuge drum cleaner provided in Example 1 or 2 is further optimized, as Figure 1-3 As shown, the mobile cleaning rack 1 further includes a storage rack 15 horizontally arranged on the rack body 11 for placing articles.

[0048] Through the above structural design, the load-bearing hollow frame below is a plane paved with round stainless steel pipes, which can be used to place other disassembled parts of the centrifuge drum, such as the lifting plate, for cleaning.

[0049] Specifically, the storage rack 15 is provided with a plurality of through holes 16 .

[0050] Through the above structural design, the through hole 16 is used to facilitate the accumulation of water on the shelf 15 to fall into the collection tank 25 at the bottom, so that the washing water can be recovered.

[0051] Specifically, the material of the storage rack 15 is stainless steel or alloy steel.

[0052] Through the above structural design, in this embodiment, the material of the storage rack 15 is stainless steel, and may also be alloy steel according to different needs.

[0053] Specifically, the collecting tank 25 is provided with a discharge port 26 , and the frame 11 is further provided with a handlebar 17 .

[0054] Through the above structural design, the collecting tank 25 prevents the medium from leaking during the cleaning process. The cleaning medium can be discharged through the discharge port 26 of the collecting tank 25 at the bottom of the cleaning chamber 2. The handle 17 is used to manually push the mobile cleaning rack 1.

[0055] The use process of the novel centrifuge drum cleaner provided by the utility model is as follows:

[0056] Taking the GEA centrifuge as an example, the drum assembly of this centrifuge consists of six groups of components, including the drum cavity, drum cover, lifting plates (2 groups), three-leaf plates and bell cover.

[0057] According to the shape, size and cleaning difficulty of the components of the centrifuge drum, the drum cavity, drum cover, trivet and bell can be transferred to the cleaning rack using a hook and a conversion ring in the horizontal crane of the factory (multiple components can be hung on the conversion ring through multiple hooks). Smaller components such as the lifting plate can be placed on the storage rack. Push the handle 17 to push the cleaning rack 1 into the cleaning chamber, start the medium conveying from the liquid inlet channel 22 to the rotary nozzles 23 arranged up and down in the cleaning chamber, and flush and clean the above-mentioned components of the centrifuge drum and the components of the centrifuge drum placed on the storage rack. After completion, the medium conveying is closed, and the medium in the cleaning process is blocked by the first water baffle 14 and the second water baffle 24 to prevent leakage. The cleaning medium is collected by the collection tank 25 and recycled when needed and discharged when not needed.
