[0038] In the pure water recovery device provided by the present utility model, the filtered water is temporarily stored in the circulation tank 1. The conductivity probe 23 can detect the conductivity of the water. The smaller the detected conductivity, the purer the water quality, so as to effectively judge the water quality after purification and avoid transporting unqualified purified water to the electrophoresis process. At the same time, when the conductivity probe 23 is attached with dirt after being used for a certain period of time, the mounting arm 21 can be moved to extend the conductivity probe 23 out of the liquid level and cleaned by the cleaning part 22. After the cleaning is completed, the conductivity probe 23 is moved back into the liquid level to improve the accuracy of the detection result. And the cleaning part 22 is placed on the liquid level to avoid the cleaning part 22 contacting the water and causing fouling, which has good practicability.

[0039] In one embodiment, please refer to Figure 4 and Figure 5 , a shaft hole 1a is provided along the radial direction at the upper end of the circulation tank 1, and the shaft hole 1a is located above the liquid level; the detection assembly 2 further includes a rotating shaft 24, the rotating shaft 24 is rotatably installed in the shaft hole 1a, and one end extends into the circulation tank 1. One end of the mounting arm 21 is connected to the rotating shaft 24, and the other end is connected to the conductivity probe 23.

[0040] In this embodiment, by rotating the rotating shaft 24 to drive the mounting arm 21 to rotate synchronously, the conductivity probe 23 can be extended and immersed in the water, with a simple structure and convenient operation.

[0041] In one embodiment, a seat body 25 is connected to the end of the rotating shaft 24 extending into the circulation tank 1.

One end of the locking bolt 26 is screwed into the locking screw hole 25b and can extend into the adjustment hole 25a to press against the mounting arm 21.

[0042] In this embodiment, the distance between the conductivity probe 23 and the rotating shaft 24 can be adjusted by tightening or loosening the bolt, so that the height of the conductivity probe 23 can be adjusted to be applicable to different water level scenarios and improve the practicability.

[0043] In one embodiment, the cleaning part 22 includes a cleaning seat 221 and a cleaning brush 222. The cleaning seat 221 is arranged above the rotating shaft 24 and is provided with a cleaning groove 221a in the horizontal direction.

It should be noted that in this solution, the height of the cleaning tank 221a is adapted to the adjustment range of the height of the conductivity probe 23. In addition, the free ends of the cleaning brushes 222 on the upper and lower side walls of the cleaning tank 221a are in contact with each other to improve the cleaning ability of the conductivity probe 23.

[0045] In one embodiment, a retaining wall 223 protrudes upward from the periphery of the lower side wall of the cleaning tank 221a; a handle 27 is provided at one end of the rotating shaft 24 located outside the circulation tank 1.

[0046] In this embodiment, by providing the retaining wall 223 on the lower side wall of the cleaning tank 221a, the dirt cleaned from the conductivity probe 23 can fall within the retaining wall 223, preventing the dirt from accidentally falling into the water and contaminating the aqueous solution. In addition, a handle 27 is further provided at one end of the rotating shaft 24 extending outside the circulation tank 1 to facilitate the operator to rotate the rotating shaft 24 and improve the convenience.

[0047] In one embodiment, the conductivity probe 23 is rotatably mounted on the mounting arm 21 around an axis in the first direction, and the first direction is the same as the axis direction of the rotating shaft 24.

[0048] In this embodiment, the conductivity probe 23 and the mounting arm 21 are rotatably connected as described above.

[0050] In this embodiment, the cleaning seat 221 is provided at the open end of the bottom tank 12, and the upper cover 11 is detachably connected to the bottom tank 12. In this way, the upper cover 11 can be regularly disassembled to clean the cleaning seat 221 and improve the cleanliness.

[0051] In one embodiment, a mating hole 12a is provided at the open end of the bottom tank 12, and a fixing hole 11a corresponding to the mating hole 12a is provided on the upper cover 11; the circulation tank 1 further includes a fastening bolt 13 and a fastening nut 14. The fastening bolt 13 passes through the fixing hole 11a and the mating hole 12a in sequence, and the fastening nut 14 is screwed onto one end of the fastening bolt 13 extending out of the mating hole 12a.

[0052] In this embodiment, through the cooperation of the fastening bolt 13, the fastening nut 14, the mating hole 12a and the connection hole, the detachable connection between the upper cover 11 and the bottom tank 12 is realized, and the structure is stable and reliable.

[0053] In one embodiment, please refer to Figure 1 and Figure 7 , the pure water recovery device further includes a filter tank 3, a filter membrane 4, a partition plate 5, a circulation pipeline 6 and a circulation pump 7. The filter membrane 4 is disposed in the filter tank 3 to divide the inner cavity of the filter tank 3 into a liquid inlet chamber and a filtrate chamber 3c. The partition plate 5 is disposed in the liquid inlet chamber to divide the liquid inlet chamber into a primary chamber 3a and a circulation chamber 3b. The primary chamber 3a and the circulation chamber 3b are respectively communicated with the filtrate chamber 3c. The circulation tank 1 is communicated with the filtrate chamber 3c, and the circulation pipeline 6 is communicated with the circulation chamber 3b and the circulation tank 1. The circulation pump 7 is disposed on the circulation pipeline 6; wherein, the pores of the filter membrane 4 in the circulation chamber 3b are smaller than the pores of the filter membrane 4 in the primary chamber 3a.

[0054] In this embodiment, when the conductivity probe 23 detects that the water quality purity is unqualified, the circulation pump 7 pumps the aqueous solution in the circulation tank 1 to the circulation chamber 3b through the circulation pipeline 6, so as to be filtered again by the relatively fine filter membrane 4 in the circulation chamber 3b to improve the water quality purity. And the filter chamber structure is relatively compact, reducing the occupied space. It should be noted that in this solution, the filtrate chamber 3c and the circulation tank 1 are communicated through a connecting pipeline 8. And a valve is provided on the connecting pipeline 8. In addition, the primary chamber 3a is communicated with a liquid inlet pipeline 9, and the circulation tank 1 is also communicated with an outlet pipeline 10.

[0055] In one embodiment, the circulation tank 1 is provided with a light-transmitting area 15 corresponding to the conductivity probe 23. The light-transmitting area 15 extends in the vertical direction and is provided with scale lines.

[0056] In this embodiment, a light-transmitting area 15 is provided corresponding to the conductivity probe 23, so as to facilitate the operator to view the dirt attachment condition of the conductivity probe 23, and at the same time facilitate observing the liquid level height in the tank body, avoiding the liquid level being too high to immerse the cleaning part 22, and avoiding the liquid level being too low to cause the conductivity probe 23 to not be able to extend into the water.

[0057] For a better understanding of the present invention, the following is a detailed description of the technical solution of the present invention in conjunction with Figures 1 to 7 :

[0058] Wastewater enters the filtration tank 3 from the primary chamber 3a, and after being purified by the filter membrane 4 corresponding to the primary chamber 3a, it enters the filtrate chamber 3c, and then is input into the circulation tank 1 through the connecting pipe 8. At this time, the conductivity probe 23 is immersed in the water to monitor the conductivity of the purified water in real time. When the monitored conductivity is qualified, the water in the circulation tank 1 is output from the liquid outlet pipe 10 to the electrophoresis process. When the monitored conductivity is unqualified, the water in the circulation tank 1 is pumped through the circulation pump 7 through the circulation pipe 6 to the circulation chamber 3b of the filtration tank 3 for re-filtration through the fine filter membrane 4 corresponding to the circulation chamber 3b. The water filtered by the circulation chamber 3b enters the re-circulation tank 1 successively through the filtrate chamber 3c and the connecting pipe 8 and is output after the conductivity is qualified. In addition, when too much dirt adheres to the surface of the conductivity probe 23, the rotating shaft 24 can be rotated to clean the conductivity probe 23 with the cleaning brush 222 to ensure the accuracy of conductivity detection.
