[0032] Embodiment 1

[0033] As Figures 1-4 shown, the application provides a regeneration treatment device for waste filter element, which comprises a cleaning assembly, the cleaning assembly comprises a cleaning cavity, a centrifugal shaft, a water pump 35 and a control part, the control part is connected with the centrifugal shaft and the water pump; the centrifugal shaft is located in the cleaning cavity, the centrifugal shaft is provided with a placing position for placing waste filter element, the end of the placing position is provided with a water inlet 33, the water inlet 33 is connected with the water pump 35; the waste filter element 13 comprises a central shaft and a membrane layer surrounding the central shaft, the central shaft is a hollow structure, and a through hole is arranged on the outer circumferential side of the central shaft;

[0034] When the waste filter element is placed in the placing position, the axis of the central shaft coincides with the axis of the centrifugal shaft; the water inlet 33 abuts against the end of the central shaft; when the control part controls the centrifugal shaft to drive the waste filter element 13 to rotate around the axis, the control part controls the water pump 35 to inject water into the central shaft through the water inlet 33.

[0035] The center axis of the waste filter element 13 is rotated while being water injected in the application. Since the center axis is a hollow structure and has a through hole on the outer periphery side, the inside of the center axis is communicated with the membrane layer outside. In the rotation process, the injected water is thrown out from the inside of the center axis through the through hole and the membrane layer, realizing the synchronous cleaning of the inside and outside of the waste filter element, effectively reducing the heavy metal ions in the waste filter element 13, realizing the recycling of the waste filter element 13, and reducing the processing cost.

[0036] Embodiment 2

[0037] As Figures 1-4 shown, the application provides a regeneration treatment device for waste filter element, which comprises a cleaning assembly, the cleaning assembly comprises a cleaning cavity, a centrifugal shaft, a water pump 35 and a control part, the control part is connected with the centrifugal shaft and the water pump; the centrifugal shaft is located in the cleaning cavity, the centrifugal shaft is provided with a placing position for placing waste filter element, the end of the placing position is provided with a water injection port 33, the water injection port 33 is connected with the water pump 35; the waste filter element 13 comprises a center axis and a membrane layer around the center axis, the center axis is a hollow structure, and the outer periphery side of the center axis is provided with a through hole; the through hole makes the hollow interval in the center axis inside communicated with the membrane layer outside.

[0038] When the waste filter element is placed in the placing position, the axis of the center axis coincides with the axis of the centrifugal shaft; the water injection port 33 abuts with the end of the center axis; when the control part controls the centrifugal shaft to rotate the waste filter element 13 around its axis, the control part controls the water pump 35 to inject water into the center axis through the water injection port 33.

[0039] Specifically, the placing position is a notch in the centrifugal shaft; the two ends of the placing position are respectively provided with a first positioning part 31 and a second positioning part 32, the first positioning part 31 comprises a first positioning protrusion 311 matched with the first end of the waste filter element 13, and the second positioning part 32 comprises a second positioning protrusion 321 matched with the second end of the waste filter element 13.

[0040] The waste filter element 13 in the application comprises a cylindrical central shaft, and a film layer is wound outside the central shaft. Correspondingly, the centrifugal shaft in the application comprises oppositely arranged first positioning member 31 and second positioning member 32, which are used for clamping the two ends of the central shaft. Since the central shaft is a hollow structure, the two ends of the central shaft are set as the first end and the second end, respectively. Therefore, the first positioning member 31 comprises a positioning protrusion matched with the first end of the waste filter element 13, and the second positioning member 32 comprises a second positioning protrusion 321 matched with the second end of the waste filter element 13. When the waste filter element 13 is fixed, the first positioning protrusion 311 is clamped into the end of the central shaft, and the second positioning protrusion 321 is clamped into the end of the central shaft, so as to fix the central shaft.

[0041] Further, the second positioning member 32 in the application is connected with a clamping driving member, which can drive the second positioning member 32 to move towards or away from the first positioning member 31, so as to adapt to waste filter elements 13 of different lengths. In actual operation, the centrifugal shaft is arranged on the cleaning table 36, that is, the first positioning member 31 and the second positioning member 32 are fixed on the cleaning table 36 at the same time. Specifically, the first positioning member 31 is fixed on the cleaning table 36 and does not move, and the second positioning member 32 is located in the slide rail 34 and is in sliding connection with the slide rail 34. The extension direction of the slide rail 34 is parallel to the axis of the centrifugal shaft. In this way, the clamping driving member can drive the second positioning member 32 to move in the slide rail 34, so as to adjust the distance between the first positioning member 31 and the second positioning member 32, and adapt to waste filter elements 13 of different lengths.

[0042] In the application, one end of the water inlet 33 is connected with the water pump 35, and the other end is in communication with the first positioning protrusion 311 in the first positioning member 31, and the hollow structure inside the central shaft is watered through the first positioning protrusion 311.

[0043] The control member in the application can control the rotation of the centrifugal shaft and the operation of the water pump 35, respectively, or the control member can be set as a double-shaft driving motor, which comprises a first output shaft and a second output shaft. The first output shaft is connected with the centrifugal shaft, and the second output shaft is connected with the water pump 35. In this way, it can be ensured that the centrifugal shaft and the water pump 35 are synchronously operated when the driving motor is operated.

[0044] The centrifugal shaft and the cleaning table 36 are located inside the cleaning cavity. When the centrifugal shaft rotates, the water inside the central shaft is ejected from the membrane layer through the through hole, and the metal ions and the chemical solution in the waste filter element 13 are ejected at the same time, so as to realize the cleaning of the waste filter element. The water pump 35 in the application can be a high-pressure water pump, so that the water injected into the central shaft through the water injection port 33 has a certain pressure. The centrifugal force makes the residual chemical solution in the waste filter element 13 more easily ejected, and the high-pressure water penetrates the central shaft from the shaft, enhances the cleaning effect, and can reduce the water consumption and wastewater treatment capacity, and protect the waste filter element 13.

[0045] The inner side wall of the cleaning cavity is sprayed with a polytetrafluoroethylene coating. The specific process parameters are as follows: before spraying, the surface of the inner side wall of the cleaning cavity is sandblasted to increase the surface roughness and improve the adhesion of the coating. Then, the polytetrafluoroethylene powder is uniformly sprayed on the surface of the inner side wall of the cleaning cavity by electrostatic spraying, the spraying thickness is controlled to be 0.2-0.3mm, and after spraying, sintering and curing at a high temperature of 380-400℃ is performed to make the coating firmly combined with the surface of the inner side wall of the cleaning cavity, effectively preventing the inner side wall of the cleaning cavity from being corroded by the chemical solution.

[0046] The bottom of the cleaning cavity is provided with a drain hole, and the side of the drain hole is provided with a concentration detection assembly. The concentration detection assembly is used to detect the metal ion concentration in the cleaning water ejected from the waste filter element 13 in the cleaning cavity. At the same time, the concentration detection assembly and the control member are in communication connection, and when the metal ion concentration detected by the concentration detection assembly is greater than or equal to the concentration threshold value, the control member controls the centrifugal shaft to continue rotating.

[0047] The concentration detection assembly is used to detect the water discharged from the cleaning cavity. If the metal ion concentration in the cleaning water is large, it indicates that the centrifugal cleaning can continue. If the metal ion concentration in the cleaning water is small, it indicates that the cleaning process is completed, and the waste filter element 13 can be taken out.

[0048] The concentration detection assembly in the application can specifically detect the concentration of metal ions according to the conductivity of the cleaning water. The metal ion concentration and its corresponding conductivity value can be stored in the system, and the metal ion concentration can be determined according to the real-time monitored conductivity.

[0049] The concentration detection assembly in the application can also be an XRF heavy metal detector. The XRF technology determines the element type and content in the sample through the fluorescent response of the cleaning water to X-rays.

[0052] Specifically, the soaking liquid is a sulfuric acid solution with a concentration of 5wt%. The waste filter element 13 is soaked in the soaking liquid for a period of time, which can make the medicine liquid in the waste filter element 13 fully dissolve into the soaking liquid. The application can also control the temperature in the soaking tank 12 to be maintained at 25-30℃, so as to accelerate the exchange speed of the medicine liquid in the waste filter element 13 and the soaking liquid, and improve the soaking effect.

[0053] As shown, Figure 1 The application can place the waste filter element 13 in the soaking cage 14, the soaking cage 14 is a hollow structure, and the hollow structure soaking cage 14 is placed into or taken out of the soaking tank 12 by the crane 11. The inner side wall of the soaking tank 12 in the application is sprayed with a polytetrafluoroethylene coating. The specific process parameters are as follows: before spraying, the inner side wall surface of the soaking tank 12 is sandblasted to increase the surface roughness and improve the coating adhesion. Then, the polytetrafluoroethylene powder is uniformly sprayed on the inner side wall surface of the soaking tank 12 by electrostatic spraying, the spraying thickness is controlled at 0.2-0.3mm, and after spraying, sintering and curing at a high temperature of 380-400℃, the coating is firmly combined with the inner side wall surface of the soaking tank 12, effectively preventing the inner side wall of the soaking tank 12 from being corroded by the chemical medicine liquid.

[0054] The clamp in the application is specifically a robot 21, the end of the robot 21 is provided with a mechanical hand 22, the side of the mechanical hand 22 is provided with a visual positioning assembly, the visual positioning assembly comprises a camera and an image processor, the camera is used for shooting the waste filter element to be clamped, and the shooting image is transmitted to the image processor, the image processor calculates the length of the waste filter element 13 by identifying the end point of the waste filter element 13 in the shooting image; the image processor is in communication connection with the centrifugal shaft, and the size of the placement position is adjusted according to the length of the waste filter element 13 calculated by the image processor. Specifically, the placement position is a notch in the centrifugal shaft; the two ends of the placement position are respectively provided with a first positioning piece 31 and a second positioning piece 32, the first positioning piece 31 comprises a first positioning protrusion 311 matched with the first end of the waste filter element 13, and the second positioning piece 32 comprises a second positioning protrusion 321 matched with the second end of the waste filter element 13. The image processor is also in communication connection with the clamping driving piece in the centrifugal shaft, the clamping driving piece determines the distance between the first positioning piece 31 and the second positioning piece 32 according to the length of the waste filter element 13, so as to ensure that the distance between the first positioning piece 31 and the second positioning piece 32 is matched with the length of the waste filter element 13.

[0055] The mechanical arm 22 in the present application is a flexible gripper, that is, a buffer layer is arranged between the mechanical arm 22 and the waste filter element 13, so as to avoid damage to the appearance of the waste filter element 13 caused by the mechanical arm 22.

[0056] In the present application, the camera is mounted on the side of the mechanical arm 22. When the mechanical arm 22 is used to grab the filter element in the soaking groove 12, the camera is used to take a picture of the filter element to be grabbed, and the picture is transmitted to the image processor. Specifically, the camera and the image processor communicate with each other through EtherCAT bus configuration, so as to ensure fast and accurate data transmission. The image processor can control the position of the mechanical arm 22 and the grabbing and releasing operation, so as to ensure that the mechanical arm 22 is grabbed to the center position of the waste filter element 13. The image processor is also in communication connection with the clamping driving member in the centrifugal shaft. The clamping driving member determines the distance between the first positioning member 31 and the second positioning member 32 according to the length of the waste filter element 13, so as to ensure that the distance between the first positioning member 31 and the second positioning member 32 is adapted to the length of the waste filter element 13.

[0057] Further, the side of the robot 21 is provided with a marking assembly; the image processor is used to identify whether the appearance of the waste filter element 13 is damaged, and the mechanical arm clamps the waste filter element 13 to the marking assembly for marking according to the identification result.

[0058] The marking assembly can be a seal, and the seal is provided with the words “used once”. The image processor is also used to identify whether the appearance of the waste filter element 13 is damaged. If the waste filter element 13 is damaged, the waste filter element 13 does not need to be stamped, and the waste filter element 13 can be directly clamped into the cleaning cavity for cleaning and then discarded. If the waste filter element 13 is not damaged, the robot 21 clamps the waste filter element 13 and moves to the position of the seal, stamps the words “used once” on the waste filter element 13, and then clamps the waste filter element 13 into the cleaning cavity for cleaning and recycling. The seal

[0059] The cleaning assembly includes a cleaning cavity, a centrifugal shaft, a water pump 35 and a control member. The centrifugal shaft is located inside the cleaning cavity, and the centrifugal shaft is provided with a placement position for placing the waste filter element. The end of the placement position is provided with a water inlet 33, and the water inlet 33 is connected with the water pump 35. The waste filter element 13 includes a central shaft and a membrane layer surrounding the central shaft. The central shaft is a hollow structure, and a through hole is arranged on the outer circumferential side of the central shaft. The through hole makes the hollow space inside the central shaft in communication with the membrane layer outside. When the waste filter element is placed in the placement position, the axis of the central shaft coincides with the axis of the centrifugal shaft. The water inlet 33 abuts against the end of the central shaft.

The concentration detection assembly is in communication with the control member. When the metal ion concentration detected by the concentration detection assembly is greater than or equal to a concentration threshold, the control member controls the centrifugal shaft to continue rotating.

[0061] During the operation of the regeneration treatment device of this application, if the metal ion content still does not meet the standard after multiple cleanings, or other key parameters of the equipment are abnormal, such as a sudden and significant drop in centrifugal speed, unstable high-pressure water pump pressure, etc., the control component will immediately issue an alarm and automatically stop the equipment operation, and record the fault information at the same time to facilitate maintenance personnel to troubleshoot the problem.

[0062] Example 4

[0063] like Figures 1-4 As shown, the present embodiment provides a method for regenerating a waste filter element, which is implemented based on the waste filter element regeneration device described in the above embodiment, and includes:

[0064] Place the discarded filter element 13 in a soaking cage 14, which is then placed in a soaking tank 12 via a crane 11. The soaking tank 12 contains a 5wt% sulfuric acid solution, and the temperature is maintained at 25-30°C. Soak for 30 minutes.

[0065] The crane 11 moves the soaking cage 14 onto the transfer table 15. The robot 21 drives the manipulator 22 to move above the soaking cage 14. The camera takes a picture of the waste filter element to be clamped and transmits the captured image to the image processor. The image processor calculates the length of the waste filter element 13 by identifying the endpoints of the waste filter element 13 in the captured image. At the same time, the image processor identifies whether the waste filter element 13 is damaged.

[0066] According to the length of the waste filter element 13, the clamping driving element drives the second positioning element 32 to move along the slide rail 34 until the size of the placement position is consistent with the length of the waste filter element 13. If the appearance of the waste filter element 13 is damaged, the robot 21 drives the mechanical hand 22 to clamp the waste filter element and place it in the placement position; if the appearance of the waste filter element 13 is not damaged, the robot 21 clamps the waste filter element 13 and moves it to the stamp position, and then stamps the waste filter element 13 with the words “used once”, and then clamps the waste filter element 13 to the placement position;

[0067] The driving motor is operated, the water pump 35 and the centrifugal shaft are simultaneously operated, and under the action of the centrifugal force, the water injected into the waste filter element 13 is thrown out from the outer peripheral side of the waste filter element 13. The rotation speed of the centrifugal shaft is controlled to control the centrifugal pressure received by the central shaft. When the waste filter element 13 is a foam filter element, the centrifugal pressure of the central shaft is controlled to be less than or equal to ≤2 kg / cm 2 When the waste filter element 13 is a non-foam filter element, the centrifugal pressure of the central shaft is controlled to be 2-5 kg / cm 2 .

[0068] The concentration detection assembly detects the metal ion concentration of the cleaning water in real time. If the metal ion concentration is ≤50 ppm, the cleaning is stopped. If the metal ion concentration is >50 ppm, the cleaning is continued. If the cleaning time reaches the preset time and the metal ion concentration is still >50 ppm, the filter element is scrapped into a hazardous waste pile.

[0069] The water pump 35 is turned off, the driving motor drives the centrifugal shaft to rotate, the filter element is spun dry, and then output is made according to specific conditions.

[0070] The application can change the waste filter element 13 from hazardous waste to general solid waste, and the second-hand filter element can be used for grinding plate filtration, realizing recycling and reuse of the filter element carrier and saving resources. Through the efficient cleaning process, the copper ion content in the waste filter element 13 is reduced from 3200 ppm to 28 ppm, with a reduction of 99.1%, reducing the pollution of heavy metals to the environment.
