[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This utility model provides a box cleaning system, such as Figures 1 to 3 As shown, the gearbox cleaning system is used to clean the gearbox housing, which includes a main housing 100 and wheel-side housings 200.

[0047] like Figures 1 to 3As shown, the housing cleaning system includes a filter box 1, a first circulation regeneration box 2, a first filter conveying assembly 3, and a second filter conveying assembly 4. The first circulation regeneration box 2 and the first filter conveying assembly 3 form a first circulation loop, and the first filter conveying assembly 3 filters and conveys the fluid within the first circulation loop. The filter box 1, the second filter conveying assembly 4, and the main housing 100 of the transmission form a second circulation loop, and the second filter conveying assembly 4 filters and conveys the fluid within the second circulation loop. The first circulation regeneration box 2 selectively conveys fluid to the filter box 1. Fluid within the main housing 100 selectively flows into the first circulation regeneration box 2.

[0048] When cleaning the interior of the main housing 100 using this housing cleaning system, the filter box 1, the second filter conveying assembly 4, and the main housing 100 are first adjusted to form a second circulation loop. The first circulation regeneration box 2 is controlled to deliver fluid into the filter box 1. The fluid flows within the second circulation loop to flush and clean the interior of the main housing 100. Debris inside the main housing 100 flows with the fluid, and the second filter conveying assembly 4 filters the debris from the fluid, effectively cleaning the debris inside the main housing 100 and achieving the effect of cleaning the interior of the main housing 100. When the cleaning of the interior of the main housing 100 is complete, the fluid inside the main housing 100 is controlled to flow into the first circulation regeneration box 2 to facilitate cleaning of the next main housing 100. Specifically, by setting up the first filter conveying assembly 3, the first circulation regeneration box 2, and the first filter conveying assembly 3 form a first circulation loop, allowing the fluid in the first circulation regeneration box 2 to be filtered and cleaned simultaneously with the cleaning of the interior of the main housing 100, thus enabling the fluid in the first circulation regeneration box 2 to be reused.

[0049] Therefore, by adopting this tank cleaning system, it is possible to clean the inside of the main tank 100 and simultaneously filter and clean the fluid in the first circulating regeneration tank 2, which can effectively improve work efficiency and has good performance. Secondly, it can effectively extend the service life of the fluid in the first circulating regeneration tank 2 and reduce cleaning costs.

[0050] In this embodiment, the fluid in the first circulation regeneration tank 2 is oil; the type of oil is the same as that in the main tank 100 during actual vehicle operation. In other embodiments, the fluid in the first circulation regeneration tank 2 can also be water or the like, which can also achieve the effect of cleaning the inside of the main tank 100.

[0051] Among them, such as Figures 1 to 3As shown, the housing cleaning system also includes a first conveying component 5, which includes a first pump 51. The first inlet and outlet of the first pump 51 are connected to the first circulation regeneration tank 2, and the second inlet and outlet of the first pump 51 can selectively connect to the filter tank 1. It is understood that the first pump 51 is a bidirectional pump; it can both convey fluid from the first circulation regeneration tank 2 to the filter tank 1 and vice versa. Specifically, the first pump 51 can convey fluid from the first circulation regeneration tank 2 to the filter tank 1, enabling the first circulation regeneration tank 2 to selectively deliver fluid to the filter tank 1. Furthermore, the first pump 51 can convey fluid from the filter tank 1 to the first circulation regeneration tank 2. Specifically, when all the main housings 100 in the previous batch are cleaned, the first pump 51 conveys all the fluid from the filter tank 1 to the first circulation regeneration tank 2, facilitating the reuse of the fluid in the first circulation regeneration tank 2 when cleaning the next batch of main housings 100, thereby further improving fluid utilization.

[0052] Optionally, such as Figures 1 to 3 As shown, a fourth differential pressure filter 101 is provided on the pipeline connecting the first inlet and outlet of the first pump 51 to the first circulation regeneration tank 2; and / or, a fourth differential pressure filter 101 is provided on the pipeline connecting the second inlet and outlet of the first pump 51 to the filter tank 1. This is to further improve the cleanliness of the fluid delivered to the filter tank 1. In this embodiment, a fourth differential pressure filter 101 is exemplaryly provided on the pipeline connecting the first inlet and outlet of the first pump 51 to the first circulation regeneration tank 2. Further, the fourth differential pressure filter 101 is a differential pressure signaling filter. When the pipeline connecting the first inlet and outlet of the first pump 51 to the first circulation regeneration tank 2 becomes blocked, the differential pressure signaling filter can issue an alarm to remind the user to clean the fourth differential pressure filter 101 in a timely manner. In other embodiments, the fourth differential pressure filter 101 is a screen filter, etc. The specific structures of the differential pressure signaling filter and the screen filter are both prior art, so they will not be described in detail here.

[0053] Preferably, the tank cleaning system further includes a recovery structure. The second inlet and outlet of the first pump 51 can selectively connect and disconnect with the recovery structure. The recovery structure can recover residual fluid inside the main tank 100 and fluid leaking from the main tank 100. The first pump 51 transports the fluid recovered by the recovery structure to the first circulation regeneration tank 2 for filtration and cleaning through the first filter conveying assembly 3, so that the fluid recovered by the recovery structure can be reused, thereby further improving the fluid utilization rate.

[0054] Specifically, such as Figure 2As shown, the recovery structure includes a recovery tank 111. The second inlet and outlet of the first pump 51 can be selectively connected to and disconnected from the recovery tank 111. The recovery tank 111 is used to recover fluid leaked from the main tank 100. This configuration enables the recovery of fluid leaked from the main tank 100. The recovered fluid leaked from the main tank 100 is then transported by the first pump 51 to the first circulating regeneration tank 2 for filtration and cleaning by the first filter conveying assembly 3.

[0055] More specifically, such as Figure 2 As shown, the first conveying assembly 5 also includes a first switching valve 52, and the first switching valve 52 is provided on the pipeline connecting the second inlet and outlet of the first pump 51 to the recycling tank 111. This allows the second inlet and outlet of the first pump 51 to be selectively connected and disconnected from the recycling tank 111.

[0056] More specifically, such as Figure 2 As shown, the recovery tank 111 is located directly below the main tank 100 in this tank cleaning system. This facilitates the collection of fluid leaking from the main tank 100 during the cleaning process. It is understood that the fluid leaking from the main tank 100 drips into the recovery tank 111 under its own gravity.

[0057] Specifically, such as Figure 3 As shown, the recycling structure also includes a recycling tank 112. The second inlet and outlet of the first pump 51 can be selectively connected to and disconnected from the recycling tank 112. The recycling tank 112 is used to recycle the fluid remaining inside the main tank 100. Specifically, after the main tank 100 is cleaned, it is transported to the intended placement location, and then the small amount of fluid remaining inside the main tank 100 is recovered through the recycling tank 112. The fluid recovered by the recycling tank 112 is then transported by the first pump 51 to the first circulating regeneration tank 2 for filtration and cleaning through the first filter conveying assembly 3.

[0058] More specifically, such as Figure 3 As shown, the first conveying assembly 5 also includes a second switching valve 53. The second switching valve 53 is provided on the pipeline connecting the second inlet and outlet of the first pump 51 to the recycling tank 112. This allows the second inlet and outlet of the first pump 51 to be selectively connected to and disconnected from the recycling tank 112.

[0059] More specifically, the recycling bin 112 is located in the area where the main body 100 is intended to be placed. The first connecting port of the main body 100 is located at the bottom of the main body 100. In this embodiment, when the main body 100 is placed at the intended location, the recycling port of the recycling bin 112 is connected to the first connecting port of the main body 100. This allows residual fluid in the main body 100 to flow directly into the recycling bin 112 for recycling. In this embodiment, the recycling port of the recycling bin 112 is connected to the first connecting port of the main body 100 by a plug-in connection. In other embodiments, a connecting connector may also be provided to connect the recycling port of the recycling bin 112 to the first connecting port of the main body 100.

[0060] Among them, such as Figures 1 to 3 As shown, the housing cleaning system also includes a second conveying assembly 6, which includes a second pump 61. The inlet of the second pump 61 is connected to the first communication port of the main housing 100, and the outlet of the second pump 61 is connected to the first circulation loop. This allows for the selective discharge of fluid from the main housing 100 to the first circulation regeneration tank 2. It is understood that the second pump 61 is a unidirectional pump, capable of only pumping and discharging fluid from the main housing 100 to the first circulation regeneration tank 2.

[0061] Preferably, such as Figures 1 to 3 As shown, the second conveying assembly 6 also includes a one-way valve 62. A one-way valve 62 is provided on the pipeline connecting the main housing 100 and the second pump 61, and / or a one-way valve 62 is provided on the pipeline connecting the second pump 61 and the second circulation loop. The one-way valve 62 is used to guide fluid to flow unidirectionally from the main housing 100 to the second circulation loop. This is to prevent backflow of fluid in the first circulation regeneration tank 2 and ensure that the fluid in the main housing 100 can only flow unidirectionally to the second circulation loop. In this embodiment, a one-way valve 62 is provided, exemplary, on the pipeline connecting the second pump 61 and the second circulation loop. In other embodiments, a one-way valve 62 is provided on the pipeline connecting the main housing 100 and the second pump 61. In other embodiments, a one-way valve 62 is provided on the pipeline connecting the main housing 100 and the second pump 61, and a one-way valve 62 is provided on the pipeline connecting the second pump 61 and the second circulation loop.

[0062] Preferably, the inlet of the second pump 61 is connected to the first communication port of the main housing 100 via a second quick-release connector. This improves the efficiency of connecting the main housing 100 and the housing cleaning system to form an integrated structure, thereby further improving cleaning efficiency. In other embodiments, the inlet of the second pump 61 can also be connected to the first communication port of the main housing 100 via other types of connectors or plug-in methods. The specific structure of the quick-release connector is prior art and will not be described in detail here. In this embodiment, the inlet of the second pump 61 is exemplaryly connected to the first communication port of the main housing 100 via a plug-in method.

[0063] Among them, such as Figures 1 to 3 As shown, the first filtration and conveying assembly 3 includes a third pump 31, a first magnetic filter 32, and a first differential pressure filter 33. The first circulation regeneration tank 2, the third pump 31, the first magnetic filter 32, and the first differential pressure filter 33 form a first circulation loop. Specifically, the first magnetic filter 32 magnetically filters magnetically adsorbable debris from the fluid flowing through it, while the first differential pressure filter 33 filters both magnetically adsorbable and non-magnetically adsorbable debris from the fluid flowing through it. This effectively improves the cleanliness of the filtered fluid and enhances the utilization rate of the fluid in the first circulation regeneration tank 2. The specific structure of the magnetic filter is prior art and will not be described in detail here.

[0064] Optionally, the number of first magnetic filters 32 is multiple. In this embodiment, such as... Figures 1 to 3 As shown, the number of first magnetic filters 32 is exemplarily set to one.

[0065] Optionally, the number of first differential pressure filters 33 is multiple. In this embodiment, such as... Figures 1 to 3 As shown, an exemplary configuration is provided with two first differential pressure filters 33. One first differential pressure filter 33 is integrated inside the first regeneration tank 2; the other first differential pressure filter 33 is located outside the first regeneration tank 2.

[0066] In this embodiment, as Figures 1 to 3 As shown, an exemplary configuration includes a first circulation regeneration tank 2, a first differential pressure filter 33, the inlet and outlet of a third pump 31, a first magnetic filter 32, and another first differential pressure filter 33, all connected sequentially to form a first circulation loop. It is understood that the position of any one of the first circulation regeneration tank 2, the third pump 31, the first magnetic filter 32, and the first differential pressure filter 33 within the first circulation loop can be adjusted according to actual operating conditions.

[0067] Preferably, the third pump 31 is a unidirectional pump.

[0068] Preferably, the first differential pressure filter 33 is a differential pressure signaling filter. When the first circulation loop becomes clogged, the differential pressure signaling filter can issue an alarm, conveniently reminding users to clean the first magnetic filter 32 and the first differential pressure filter 33 in a timely manner, and conveniently reminding users to maintain the first circulation loop. In other embodiments, the first differential pressure filter 33 is a screen filter or the like.

[0069] In this embodiment, as Figures 1 to 3As shown, the outlet of the check valve 62 is exemplarily connected to the pipeline connecting the outlet of the third pump 31 and the first magnetic filter 32. It is understood that the connection position of the outlet of the check valve 62 to the first circulation loop can also be adjusted according to actual operating conditions.

[0070] In this embodiment, the main housing 100 is made of iron substrate, so the first magnetic filter 32 can effectively magnetically filter the iron filings in the fluid flowing through the first magnetic filter 32.

[0071] Among them, such as Figures 1 to 3 As shown, the second filtration and delivery assembly 4 includes a fourth pump 41, a second magnetic filter 42, and a second differential pressure filter 43. The filter box 1, the fourth pump 41, the second magnetic filter 42, and the second differential pressure filter 43 form a communication channel. The input end of the communication channel can be connected to the second communication port of the main housing 100, and the output end of the communication channel can be connected to the third communication port of the main housing 100. This allows the filter box 1, the second filtration and delivery assembly 4, and the main housing 100 of the transmission to selectively form a second circulation loop. Specifically, the second magnetic filter 42 can magnetically filter magnetically adsorbable debris in the fluid flowing through it, and the second differential pressure filter 43 can filter both magnetically adsorbable and non-magnetically adsorbable debris flowing through it. This effectively improves the cleanliness of the filtered fluid. Compared to the prior art which uses multiple filters with different filtration levels, this structure is simple and effectively improves the cleaning effect on the inside of the main housing 100.

[0072] Optionally, the number of second magnetic filters 42 is multiple. In this embodiment, such as... Figures 1 to 3 As shown, the number of second magnetic filters 42 is exemplarily set to one.

[0073] Optionally, the number of second differential pressure filters 43 is multiple. In this embodiment, such as... Figures 1 to 3 As shown, the exemplary configuration is that the number of second differential pressure filters 43 is one.

The inlet of the second magnetic filter 42 is connected to the second communication port of the main housing 100, and the outlet of the fourth pump 41 is connected to the third communication port of the main housing 100. The fourth pump 41 is integrated inside the filter box 1 to form a second circulation loop. It is understood that the position of any one of the second magnetic filter 42, the second differential pressure filter 43, the filter box 1, and the fourth pump 41 in the communication path can be adjusted according to actual working conditions.

[0075] Preferably, the fourth pump 41 is a unidirectional pump.

[0076] Preferably, the second differential pressure filter 43 is a differential pressure signaling filter. When the second circulation loop becomes clogged, the differential pressure signaling filter can issue an alarm, conveniently reminding users to clean the second magnetic filter 42 and the second differential pressure filter 43 in a timely manner, and conveniently reminding users to maintain the second circulation loop. In other embodiments, the second differential pressure filter 43 is a screen filter or the like.

[0077] Preferably, such as Figures 1 to 3 As shown, the second filter delivery assembly 4 also includes two first quick-release connectors 44. One first quick-release connector 44 is used to connect the input end of the communication passage to the second communication port of the main housing 100, and the other first quick-release connector 44 is used to connect the output end of the communication passage to the third communication port of the main housing 100. This can improve the efficiency of connecting the main housing 100 and the housing cleaning system to form an integrated structure, thereby further improving cleaning efficiency. In this embodiment, one first quick-release connector 44 is used to connect the inlet of the second magnetic filter 42 to the second communication port of the main housing 100, and the other first quick-release connector 44 is used to connect the outlet of the fourth pump 41 to the third communication port of the main housing 100. In other embodiments, the inlet of the second magnetic filter 42 can also be connected to the second communication port of the main housing 100, and the outlet of the fourth pump 41 can be connected to the third communication port of the main housing 100, through other types of connectors.

[0078] Preferably, such as Figures 1 to 3 As shown, a third switching valve 45 is provided on the connecting passage.

[0079] In this embodiment, as Figures 1 to 3 As shown, a third switching valve 45 is provided on the pipeline connecting the inlet of filter box 1 to the second differential pressure filter 43, and a third switching valve 45 is also provided on the pipeline connecting the outlet of filter box 1 to the main housing 100. This allows the filter box 1 and the main housing 100 to be connected or disconnected. For example, two third switching valves 45 are provided on the pipeline connecting the outlet of filter box 1 to the main housing 100.

[0080] In this embodiment, as Figures 1 to 3As shown, the second inlet and outlet of the first pump 51 are connected to a set pipeline, which is a pipeline connecting the third switching valve 45 and the second differential pressure filter 43. The third switching valve 45 is a third switching valve 45 on the pipeline connecting the inlet of the filter box 1 and the second differential pressure filter 43. Further, the first conveying assembly 5 also includes a fourth switching valve 54, which is provided on the pipeline connecting the second inlet and outlet of the first pump 51 to the set pipeline. The third switching valve 45 and the fourth switching valve 54 work together to selectively connect and disconnect the second inlet and outlet of the first pump 51 from the filter box 1. The first pump 51, the first switching valve 52, the second switching valve 53, the third switching valve 45, and the fourth switching valve 54 work together to selectively pump fluid from at least one of the recovery tank 111, the recovery box 112, and the filter box 1 to the first circulation regeneration box 2, and to selectively pump fluid from the first circulation regeneration box 2 to the filter box 1.

[0081] Optionally, such as Figures 1 to 3 As shown, the housing cleaning system also includes a replenishment tank 121, which can be selectively switched on and off with the filter tank 1. Further, as... Figures 1 to 3 As shown, the replenishment tank 121 is located above the filter tank 1; or, a seventh pump is installed on the pipeline connecting the replenishment tank 121 and the filter tank 1. This allows fluid to be replenished into the filter tank 1 through the replenishment tank 121. Furthermore, the type of fluid in the replenishment tank 121 is the same as the type of fluid in the first circulation regeneration tank 2. Specifically, fluid can also be replenished into the filter tank 1 through the first circulation regeneration tank 2.

[0082] It is understandable that, such as Figures 1 to 3 As shown, with the supply tank 121 located above the filter tank 1, the fluid inside the supply tank 121 can flow into the filter tank 1 under its own gravity. If a seventh pump is installed on the pipeline connecting the supply tank 121 and the filter tank 1, the fluid inside the supply tank 121 can be pumped into the filter tank 1 by the seventh pump. In this case, the positions of the supply tank 121 and the filter tank 1 are not limited.

[0083] Specifically, such as Figures 1 to 3 As shown, the housing cleaning system also includes a fifth switching valve 122, which is installed on the pipeline connecting the supply tank 121 and the filter tank 1. This allows the supply tank 121 to be selectively connected to and disconnected from the filter tank 1.

[0084] Among them, such as Figure 2 and Figure 3As shown, the tank cleaning system also includes a second circulation regeneration tank 7, a fifth pump 8, and a third filter conveying assembly 9. The first inlet and outlet of the fifth pump 8 are connected to the second circulation regeneration tank 7, and the second inlet and outlet of the fifth pump 8 are connected to the wheel-side tank 200. The second circulation regeneration tank 7 and the third filter conveying assembly 9 form a third circulation loop, which filters and conveys the fluid within the third circulation loop. It is understood that the fifth pump 8 is a bidirectional pump. The fifth pump 8 can pump the fluid in the second circulation regeneration tank 7 to the wheel-side tank 200 for rinsing and cleaning, and can also pump the fluid after rinsing and cleaning the wheel-side tank 200 back to the second circulation regeneration tank 7. By setting the second circulation regeneration tank 7 and the third filter conveying assembly 9 to form a third circulation loop, the fluid in the second circulation regeneration tank 7 can be simultaneously filtered and cleaned by the third filter conveying assembly 9 during the rinsing and cleaning process of the wheel-side tank 200, thus allowing the fluid in the second circulation regeneration tank 7 to be reused.

[0085] Therefore, it can clean the inside of the wheel-side housing 200 and simultaneously filter and clean the fluid in the second circulation regeneration tank 7, which can further improve the working efficiency of the housing cleaning system; secondly, it can effectively extend the service life of the fluid in the second circulation regeneration tank 7 and reduce cleaning costs.

[0086] In this embodiment, the fluid in the second circulation regeneration tank 7 is oil; the type of oil is the same as that in the wheel-side housing 200 during actual vehicle operation. In other embodiments, the fluid in the second circulation regeneration tank 7 can also be water or the like, which can also achieve the effect of cleaning the wheel-side housing 200.

[0087] In this embodiment, as Figure 2 and Figure 3 As shown, there are two wheel-side housings 200. Both the wheel-side housing 200 and the main housing 100 are part of the transmission structure. The specific structure of the transmission is prior art and will not be described in detail here.

[0088] Because the wheel-side housing 200 is small in size, in this embodiment, the fifth pump 8 is preferably a bidirectional pump; the first inlet and outlet of the fifth pump 8 are connected to the second circulation regeneration tank 7, and the second inlet and outlet of the fifth pump 8 can be connected to the wheel-side housing 200 of the transmission. In other embodiments, the second circulation regeneration tank 7 and the wheel-side housing 200 form a fourth circulation loop; the fifth pump 8 is disposed in the fourth circulation loop. This also enables the fifth pump 8 to pump the fluid in the second circulation regeneration tank 7 into the wheel-side housing 200 to flush and clean the inside of the wheel-side housing 200, and also enables the pumping of the fluid after flushing and cleaning the inside of the wheel-side housing 200 into the second circulation regeneration tank 7.

[0089] Among them, such as Figure 2 and Figure 3 As shown, the third filtration and delivery assembly 9 includes a sixth pump 91, a third magnetic filter 92, and a third differential pressure filter 93. The second circulation regeneration tank 7, the sixth pump 91, the third magnetic filter 92, and the third differential pressure filter 93 form a third circulation loop. Specifically, the third magnetic filter 92 magnetically filters magnetically adsorbable debris from the fluid flowing through it, and the third differential pressure filter 93 filters both magnetically adsorbable and non-magnetically adsorbable debris from the fluid flowing through it. This effectively improves the cleanliness of the filtered fluid and enhances the utilization rate of the fluid in the second circulation regeneration tank 7.

[0090] Optionally, the number of third magnetic filters 92 is multiple. In this embodiment, such as... Figure 2 and Figure 3 As shown, the exemplary configuration is that the number of third magnetic filters 92 is one.

[0091] Optionally, the number of third differential pressure filters 93 is multiple. In this embodiment, such as... Figure 2 and Figure 3 As shown, an exemplary configuration uses two third differential pressure filters 93.

[0092] In this embodiment, as Figure 2 and Figure 3 As shown, an exemplary configuration includes a second regeneration tank 7, one of its third differential pressure filters 93, the inlet of the sixth pump 91, the outlet of the sixth pump 91, a third magnetic filter 92, and another third differential pressure filter 93 connected in sequence. It is understood that the position of any one of the second regeneration tank 7, the sixth pump 91, the third magnetic filter 92, and the third differential pressure filter 93 in the third regeneration loop can be adjusted according to actual operating conditions.

[0093] Preferably, the sixth pump 91 is a unidirectional pump.

[0094] Preferably, the third differential pressure filter 93 is a differential pressure signaling filter. When the third circulation loop becomes clogged, the differential pressure signaling filter can issue an alarm, conveniently reminding users to clean the third magnetic filter 92 and the third differential pressure filter 93 in a timely manner, thus facilitating maintenance of the third circulation loop. In other embodiments, the third differential pressure filter 93 is a screen filter or the like.

[0095] In this embodiment, the wheel-side housing 200 is made of iron substrate, so the iron filings in the fluid flowing through the third magnetic filter 92 can be effectively magnetically filtered.

[0096] Preferably, the first switching valve 52, the second switching valve 53, the third switching valve 45, the fourth switching valve 54, and the fifth switching valve 122 are all electromagnetic switching valves. As an alternative, the first switching valve 52, the second switching valve 53, the third switching valve 45, the fourth switching valve 54, and the fifth switching valve 122 are all manual switching valves.

[0097] In this embodiment, as Figure 1-3 As shown, the working process of this enclosure cleaning system is as follows:

[0098] Connect the inlet of the second magnetic filter 42 to the second communication port of the main housing 100 via one of the first quick-release connectors 44, and connect the outlet of the fourth pump 41 to the third communication port of the main housing 100 via another first quick-release connector 44. Open the three third switch valves 45 and start the fourth pump 41. The fourth pump 41 causes fluid to flow in the second circulation loop, flushing and cleaning the inside of the main housing 100. Connect the inlet of the second pump 61 to the first communication port of the main housing 100, and keep the second pump 61 closed.

[0099] During the flushing process inside the main chamber 100, the third pump 31 is simultaneously turned on, and the fluid flows in the first circulation loop through the third pump 31. The first magnetic filter 32 and the first differential pressure filter 33 filter the debris in the fluid in the first circulation loop.

[0100] During the flushing process inside the main chamber 100, the sixth pump 91 is simultaneously activated, allowing the fluid to flow in the third circulation loop. The third magnetic filter 92 and the third differential pressure filter 93 filter out debris in the fluid within the third circulation loop.

[0101] Connect the second inlet and outlet of the fifth pump 8 to the wheel rim housing 200. Before the main housing 100 is finished being flushed, turn on the fifth pump 8 to pump the fluid in the second circulation regeneration tank 7 into the wheel rim housing 200 to flush and clean the inside of the wheel rim housing 200. Then pump the fluid after flushing and cleaning the inside of the wheel rim housing 200 back into the second circulation regeneration tank 7. After the wheel rim housing 200 is finished being flushed, turn off the fifth pump 8.

[0102] When rinsing the main housing 100 is complete, turn off the fourth pump 41, the third pump 31, and the sixth pump 91; turn on the second pump 61, which pumps the fluid inside the main housing 100 into the first circulating regeneration tank 2. Then, disconnect the inlet of the second magnetic filter 42 from the second communication port of the main housing 100 through one of its first quick-release connectors 44; disconnect the outlet of the fourth pump 41 from the third communication port of the main housing 100 through another first quick-release connector 44; disconnect the inlet of the filter box 1 and the second differential pressure filter 43 through one of its third switch valves 45, and disconnect the outlet of the filter box 1 from its corresponding quick-release connector through two other third switch valves 45; disconnect the inlet of the second pump 61 from the first communication port of the main housing 100; move the main housing 100 and the wheel-side housing 200 as a whole to the desired placement position so that the next main housing 100 and wheel-side housing 200 can be cleaned.

[0103] Therefore, by adopting this tank cleaning system, the main tank 100 and the wheel side tank 200 can be cleaned relatively independently, and the quality and efficiency of cleaning the main tank 100 and the wheel side tank 200 can be effectively improved. Secondly, it can effectively improve the service life of the fluid in the first circulating regeneration tank 2 and the service life of the fluid in the second circulating regeneration tank 7.
