[0030] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0031] like Figure 1 , 2 As shown, a new energy controller housing cooling water channel cleaning device 2 is used to clean products, including a frame 1, on which a cleaning device 2, a filtering device 3, a high-pressure pump 4 and a clean water pool 5 are arranged, and the cleaning device 2 includes a forward flushing mechanism 21 and a backwashing mechanism 22, and the water outlet of the clean water pool 5 is connected to the forward flushing mechanism 21 and the backwashing mechanism 22, and the water return port is connected to the filtering device 3;

[0032] It includes a forward flushing state and a backwashing state. In the forward flushing state, the water inlet of the cooling water channel of the product is connected to the forward flushing mechanism 21, and the water outlet is connected to the filter device 3; in the backwashing state, the water outlet of the cooling water channel of the product is connected to the backwashing mechanism 22, and the water inlet is connected to the filter device 3;

[0033] The clean water pool 5 is provided with a first water level sensor 6;

[0034] It also includes a control module 7 , which is electrically connected to the forward flushing mechanism 21 , the backwashing mechanism 22 , the high-pressure pump 4 , the filtering device 3 and the first water level sensor 6 .

[0036] During forward flushing, the control module 7 controls the forward flushing mechanism 21 to open and the backwashing mechanism 22 to close. The clean water forms high-pressure water under the action of the high-pressure pump 4, and enters the cooling water channel of the product after passing through the outlet pipe and the forward flushing mechanism 21 to remove impurities such as aluminum chips in the cooling water channel. Then, the water carrying impurities is discharged and filtered by the filter device 3 to form clean water that flows back to the clean water pool 5.

[0037] During backwashing, the control module 7 controls the backwashing mechanism 22 to be closed and the forward flushing mechanism 21 to be opened. The clean water forms high-pressure water under the action of the high-pressure pump 4, and enters the cooling water channel of the product after passing through the water outlet pipe and the backwashing mechanism 22, and removes impurities such as aluminum chips in the cooling water channel. Then, the water carrying impurities is discharged and filtered by the filter device 3 to form clean water that flows back to the clean water pool 5;

[0038] The above structure cleans the cooling water channel of the product through multiple positive and negative high-pressure flushing, thereby efficiently and reliably removing impurities such as aluminum chips in the cooling water channel, so that the cleanliness of the cooling water channel meets the product requirements.

[0039] In this embodiment, the clean water level in the clean water pool 5 is monitored in real time by the first water level sensor 6. When the clean water level exceeds the upper limit or is lower than the lower limit, the control module 7 displays and issues an alarm to ensure that the clean water level is within the set range.

[0040] In this embodiment, the water temperature, water level and related cleaning parameters of the cleaning water can be parameterized on the control module 7 .

Clean water enters the cooling water channel through the outlet pipe 1b, the first diversion block 8, the first inlet pipe 1a, and the second diversion block 9 in sequence to remove impurities such as aluminum chips in the cooling water channel. Then, the water carrying impurities flowing out of the cooling water channel flows through the first drain pipe 2a to the filter device 3 for filtration, and then forms clean water that flows back to the clean water pool 5.

[0051] During back flushing, the third valve 221 and the fourth valve 222 are opened (at this time, the first valve 211 and the second valve 212 are closed), so that the inlet and outlet of the cooling water channel of the product are connected through the first water channel interface 95 and the second water channel interface 96, and the clean water enters the cooling water channel through the outlet pipe 1b, the first diversion block 8, the second water inlet pipe 3a, and the second diversion block 9 in sequence to remove impurities such as aluminum chips in the cooling water channel, and then the water carrying impurities flowing out of the cooling water channel flows through the second drain pipe 4a to the filter device 3 for filtration, and then forms clean water that flows back to the clean water pool 5.

[0052] In this embodiment, the first valve 211 , the second valve 212 , the third valve 221 and the fourth valve 222 are all solenoid valves.

[0053] Further, such as Figure 1 , 2 As shown, the filtering device 3 includes a water collecting tank 31, a primary filtering component 32 and a secondary filtering component 33 which are connected in sequence by pipes, the primary filtering component 32 is located below the water collecting tank 31, and the first drainage interface 93 and the second drainage interface 94 are connected to the water collecting tank 31 at one end away from the second diversion block 9; the secondary filtering component 33 is connected to the clean water pool 5 through the return pipe 2b.

[0054] In this embodiment, the water from forward and reverse flushing is collected by the water collection tank 31 and collected into the primary filter component 32, large particles of impurities in the water are filtered out by the primary filter component 32, and small particles of impurities in the water are filtered out by the secondary filter component 33; the above structure adopts a multi-stage filtering structure to achieve efficient filtration of the cleaning water, and at the same time, impurities such as aluminum chips in the cleaning water are concentrated and effectively collected, thereby achieving energy saving and environmental protection.

[0055] Further, such as Figure 1 , 2 As shown, the primary filter component 32 includes a sewage treatment tank 321, in which a partition 322 is arranged. The partition 322 enables the sewage treatment tank 321 to form a sedimentation tank 3211 and a clarification tank 3212 which are interconnected at the upper ends. A filter net 323 is arranged on the water inlet of the sedimentation tank 3211. The secondary filter component 33 is connected to the clarification tank 3212; and a second water level sensor 10 is arranged on the clarification tank 3212.

[0056] In this embodiment, a partition 322 is provided in the sewage treatment tank 321, and the partition 322 enables the sewage treatment tank 321 to form a sedimentation tank 3211 and a clarification tank 3212. The filter net 323 is provided at the water inlet of the sedimentation tank 3211, and the secondary filter component 33 is connected to the clarification tank 3212; the filter net 323 has a filtration aperture of 1 mm, which is used to filter large particles of impurities in the water, and then enters the secondary filter component 33 after purification in the sedimentation tank 3211 and the clarification tank 3212.

[0057] In this embodiment, the clarified water level in the clarification tank 3212 is monitored in real time by the second water level sensor 10.

The first filter 332 is a 20μ filter bag filter, and the second filter is a 5μ filter bag filter, which are respectively used to filter fine and tiny particles in the water, thereby achieving efficient filtration of cleaning water.

[0061] Further, such as Figure 1 , 2 As shown, the first filter 332 and the second filter 333 are provided with a first pressure gauge 100 and a second pressure gauge 200 respectively.

[0062] In this embodiment, the effective filtering performance of the filter is determined by real-time monitoring of the pressure values ​​of the first pressure gauge 100 and the second pressure gauge 200. When the pressure value is lower than the set value, it indicates that the filter bag of the filter needs to be cleaned to ensure the filtering effect.

[0063] Further, such as Figure 1 , 2 As shown, a protective plate 311 is provided at the mouth of the water collecting tank 31 .

[0064] In this embodiment, the above structure effectively prevents the cleaning water flowing out from the first drainage interface 93 and the second drainage interface 94 from splashing to the outside of the water collection tank 31, thus playing a good protective role.
