[0024] This application discloses a filter element cleaning device, referring to... Figure 1The filter element cleaning device includes a frame 1, on which three cleaning tanks are arranged horizontally: a pre-cleaning tank 2, a rinsing tank 3, and an ultrasonic cleaning tank 4. The ultrasonic cleaning tank 4 is equipped with an ultrasonic cleaning mechanism. The pre-cleaning tank 2 is used to remove large particulate impurities, the rinsing tank 3 is used to remove residual contaminants, and the ultrasonic cleaning tank 4 is used to remove microscopic impurities. A transmission system 5 spans the three cleaning tanks at the top of the frame. A basket 6 for carrying the filter element is suspended on the transmission system 5. The transmission system 5 can drive the basket 6 to move horizontally along the three cleaning tanks and to rise and fall vertically above the corresponding tanks. A nickel recovery system 7 is provided on the frame to treat the waste liquid from the pre-cleaning tank and the rinsing tank. The frame is also equipped with an inlet / outlet water system 8 and a control cabinet 9. The control cabinet 9 is equipped with a display to show the operating status of the device.

[0025] Reference Figure 2 Each of the three cleaning tanks is equipped with a ring-shaped water supply pipe 10, a float level sensor 11, and a liquid outlet 12. The ring-shaped water supply pipe 10 facilitates uniform water distribution and stable liquid replenishment. The float level sensor 11 is used to detect the liquid level in the tank. The liquid outlet 12 is equipped with a valve 13 for controlling the opening and closing of the liquid outlet. The liquid outlet of the pre-cleaning tank 2 is equipped with a Y-type filter, and the liquid outlet of the rinsing tank 3 is equipped with a bag filter. The pre-cleaning tank 2 is also equipped with a stirring paddle 14, an electric heating rod 15, and a motor that drives the stirring paddle 14 to rotate. The stirring paddle 14, together with the electric heating rod 15, accelerates the removal of impurities from the filter element. The rinsing tank 3 automatically replenishes liquid through the annular water supply pipe 10 according to the float level sensor 11 to continuously dilute pollutants. The immersion and soaking promotes the diffusion and removal of residual impurities. At the same time, the waste is filtered and discharged through the bag filter at the outlet. The timing of the discharge and replenishment is coordinated to form a partial replacement to avoid secondary adhesion of pollutants. The soluble nickel salts and small particles remaining after pre-cleaning are removed. The ultrasonic cleaning mechanism includes several ultrasonic transducers 16 set at the bottom of the ultrasonic cleaning tank 4. An ultrasonic generator 17 is also set on the frame 1. The ultrasonic generator 17 drives the ultrasonic transducers 16.

[0026] Reference Figure 3The transmission system 5 includes a lateral drive assembly and a vertical lifting assembly. The lateral drive assembly includes a ball screw mechanism 18 mounted on the top of the frame. The ball screw mechanism 18 includes a screw 19, which is rotatably mounted on the top of the frame 1. The top of the frame 1 is also provided with two parallel linear guide rails 20. A sliding plate 21 is threaded onto the screw 19. Two rollers are provided on the two sides of the sliding plate 21 that are parallel to the linear guide rails 20. The rollers can roll along the linear guide rails 20. The screw 19 drives the sliding plate 21 to move laterally along the linear guide rails 20, so that the basket 6 moves between the three cleaning pools. The vertical lifting assembly includes an electric push rod 22, which connects the sliding plate 21 and the basket 6, so that the basket 6 can be immersed in and leave the cleaning pool. The frame 1 is also provided with a servo motor 23 that drives the screw 19. The basket 6 has a hollow structure to facilitate the soaking of the filter element. The basket 6 is equipped with an elastic silicone bracket 24 for clamping and fixing the filter element. The top of the basket 6 is equipped with a quick-release lifting lug, which is connected to an electric push rod 22.

[0027] refer to Figure 4 The water inlet and outlet system 8 includes an inlet pipe 25, an outlet pipe 26, and a water pump for conveying water flow. The inlet pipe 25 connects the water source to the annular water supply pipe 10 of each pool, and the outlet pipe 26 connects the liquid outlet 12 of each pool to the nickel recovery system 7.

[0028] The working process of this utility model is as follows:

[0029] The device is activated, and water begins to be added to the pre-cleaning tank 2 and the rinsing tank 3. The annular water supply pipe 10 in the tank controls the liquid level in the tank according to the float level sensor 11. At this time, the basket 6 is located above the pre-cleaning tank 2. The filter element to be cleaned is inserted into the elastic silicone holder 24 in the basket 6 and fixed. Then, the electric push rod 22 drives the basket 6 to descend, and the filter element is immersed in the tank. The stirring paddle 14 and the electric heating rod 15 in the pre-cleaning tank 2 are activated and continue for 3 minutes. The basket 6 rises, the valve 13 of the pre-cleaning tank 2 opens, and the nickel-containing waste liquid is discharged into the outlet pipe 26 through the Y-type filter. After the liquid is discharged, the valve 13 closes, and the ball screw mechanism 18 drives the basket 6 to move to the rinsing tank 3. The filter element is immersed in the rinsing tank for 9 minutes. The annular water supply pipe 10 continuously replenishes water according to the float level sensor 11 to maintain a stable liquid level. Every 3 minutes of immersion, 1 / 3 of the liquid is discharged while simultaneously replenishing. The basket 6 rises, and the valve 13 of the rinsing tank 3 opens, allowing the nickel-containing waste liquid to pass through the bag filter and drain into the outlet pipe 26. The valve 13 closes, and the basket 6 is moved to the ultrasonic cleaning tank 4. The nickel recovery system 7 is activated to recover the waste liquid. Pure water is injected into the annular water distribution pipe 10 of the ultrasonic cleaning tank 4, and the ultrasonic generator 17 is activated. The ultrasonic transducer 16 operates intermittently for 8 minutes, with the pure water replacing the filter element twice to ensure no residue remains on the surface. The basket 6 rises, and the filter element is removed from the basket 6. After drying, the filter element can be reused.

[0030] This invention effectively removes impurities from the surface and interior of the filter element through two-stage differentiated cleaning and ultrasonic enhanced cleaning, enabling the filter element to be reused. At the same time, it can also collect and recycle nickel-containing waste liquid generated during the cleaning process.
