[0021] The utility model provides a countercurrent cleaning device for multiple metal strips, which comprises: a frame, a water storage tank is installed on the frame, a plurality of partitions are arranged in the water storage tank, the plurality of partitions divide the water storage tank into a plurality of water storage chambers and a sewage discharge chamber in sequence, a sewage main pipe is provided below the water storage tank, and a third sewage discharge pipe is connected between the sewage discharge chamber and the sewage main pipe; a plurality of cleaning troughs are provided and erected above the water storage tank; a first water inlet pipe is connected to the water storage chamber away from the sewage discharge chamber and located on the other side of the sewage discharge chamber, and the first water inlet pipe is used to supply water to the water storage chamber; wherein the metal strip runs in the direction from the sewage discharge chamber to the water storage chamber; the height of the partition is lower than the height of the water storage tank; a second water inlet pipe and a drainage pipe are respectively connected between the cleaning trough and the water storage chamber. Under the above structure, since the height of the partition is lower than the height of the water tank, when the first water inlet pipe is filled with water in the water storage chamber connected to it, the water flow will flow over the partition into the adjacent water storage chamber, thereby filling all the water storage chambers with water; the cleaning tank injects the water in the water storage chamber into it through the second water inlet pipe to clean the metal strip, and then discharges it to the corresponding water storage chamber through the drain pipe, thereby forming a water cycle; and the direction of movement of the metal strip is opposite to the direction of water injection into the water storage chamber.

[0022] A pH probe and a conductivity probe are also installed in the water storage chamber, which is away from the sewage chamber and located on the other side of the sewage chamber. When the pH value or conductivity of the water in the water storage chamber detected by the pH probe and the conductivity probe reaches the set value, the electronic control valve on the first water inlet pipe opens to continue to inject clean water into the water storage chamber. The heavily polluted water in the water storage chamber flows toward the sewage chamber under the action of the newly injected water flow and is discharged from the third sewage pipe. Chemical agents are then added as needed. Therefore, this multi-metal strip countercurrent cleaning device can achieve autonomous water replacement while also discharging heavily polluted water sources as needed and retaining lightly polluted water sources as the water source for the first cleaning. This makes the device more water-efficient and chemical-efficient, reducing the cleaning cost of its metal strips. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-5 As shown, the utility model provides a countercurrent cleaning device for multiple metal strips, which includes a frame 1, a water tank 3 is installed on the frame 1, and a plurality of partitions 31 are arranged inside the water tank 3. The plurality of partitions 31 divide the water tank 3 into multiple water storage chambers 32 and a sewage chamber 33 in sequence. A sewage main pipe 7 is provided below the water tank 3, and a third sewage pipe 10 is connected between the sewage chamber 33 and the sewage main pipe 7; a plurality of cleaning tanks 2 are provided and erected above the water tank 3. The cleaning tanks 2 are used for cleaning the metal strips 4; a first water inlet pipe 11 is connected to the water storage chamber 32 away from the sewage chamber 33 and located on the other side of the sewage chamber 33, and the first water inlet pipe 11 is used to supply water to the water storage chamber 32;

[0038] Among them, the metal material belt 4 runs along the sewage chamber 33 towards the water storage chamber 32; the height of the partition 31 is lower than the height of the water tank 3; the second water inlet pipe 14 and the drain pipe 15 are respectively connected between the cleaning tank 2 and the water storage chamber 32.

[0039] The utility model provides a countercurrent cleaning device for multiple metal strips. By setting the height of the partition 31 to be lower than the height of the water tank 3, when the first water inlet pipe 11 is filled with water in the water storage chamber 32 connected to it, the water flow will flow over the partition 31 into the adjacent water storage chamber 32, thereby filling all the water storage chambers 32 with water; the cleaning tank 2 injects the water in the water storage chamber 32 into it through the second water inlet pipe 14 to clean the metal strip 4, and then discharges it to the corresponding water storage chamber 32 through the drain pipe 15, thereby forming a water cycle; and the direction of movement of the metal strip 4 is opposite to the direction of the water flow injected into the water storage chamber 32. Therefore, the cleaning tank 2 located above the sewage chamber 33 is the first cleaning of the metal strip 4, that is, the degree of water contamination in the water storage chamber 32 increases from the water storage chamber 32 connected to the first water inlet pipe 11 toward the sewage chamber 33.

[0040] A pH probe 34 and a conductivity probe 35 are also provided in the water storage chamber 32, which is away from the sewage chamber 33 and located on the other side of the sewage chamber 33. When the pH value or conductivity of the water in the water storage chamber 32 detected by the pH probe 34 and the conductivity probe 35 reaches a set value, the electronic control valve 12 on the first water inlet pipe 11 opens to continue injecting clean water into the water storage chamber 32. The heavily polluted water in the water storage chamber 32 flows toward the sewage chamber 33 under the action of the newly injected water flow and is discharged from the third sewage pipe 10. Chemical agents are then added as needed. Therefore, the countercurrent cleaning device for multiple metal strips can realize autonomous water replacement while also discharging heavily polluted water sources as needed and retaining lightly polluted water sources as the water source for the first cleaning, making the device more water-efficient and chemical-efficient, and reducing the cleaning cost of its metal strips 4.

The water pump 16 injects the water in the water storage chamber 32 into the cleaning tank 2 through the second water inlet pipe 14 to clean the metal strip 4. The cleaned water source then flows from the two drainage pipes 15 into the corresponding water storage chamber 32 to form a water cycle, so that the water source in the water storage chamber 32 can be reused many times. When the conductivity and pH value of the water source in the water storage chamber 32 reach the set value, the first water inlet pipe 11 continues to inject water into the water storage chamber 32, so that the countercurrent cleaning device for multiple metal strips can realize autonomous water change while also being able to discharge heavily polluted water sources as needed and retain lightly polluted water sources as the water source for the first cleaning, thereby saving more water resources.

This setting is also for the convenience of cleaning the water after the cleaning operation is completed or the water storage chamber needs to be cleaned. When the cavity 32 is cleaned, the water in the water storage cavity 32 can be discharged from the second sewage pipe 9 conveniently and quickly. In order to enable the device to better realize autonomous water replacement, an electronic control valve 12 is provided on the first water inlet pipe 11, and two groups of detection modules 6 are provided on the top of the frame 1. The electronic control valve 12, the pH probe 34 and the conductivity probe 35 are respectively communicated with the two groups of detection modules 6; the electronic control valve 12 can cooperate with the pH probe 34 and the conductivity probe 35 to realize water injection into the water storage cavity 32 and replacement of new water source.
