Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution for a shunt device for detecting the concentration of polishing liquid:

[0022] Embodiment 1:

[0023] As Figures 1-3 shown, a shunt device for detecting the concentration of polishing liquid includes a shunt frame 1. A confluence cylinder 2 is arranged at the top of the shunt frame 1. A diversion pipe 3 is arranged at the top of the confluence cylinder 2. An auxiliary cylinder 4 is rotatably installed at the bottom of the confluence cylinder 2. A diversion net 6 is arranged inside the confluence cylinder 2. A second filtrate tray 9 is arranged inside the auxiliary cylinder 4. A plurality of shunt pipes 5 are arranged at the bottom of the auxiliary cylinder 4. A micro - motor 10 is arranged on one side of the top of the shunt frame 1. The output shaft of the micro - motor 10 is in transmission connection with a transmission rod 11. One end of the transmission rod 11 is sleeved with a plurality of shelving frames 14. Storage cylinders 15 are placed inside the plurality of shelving frames 14. The other end of the transmission rod 11 is fixedly sleeved with a first gear 12. The auxiliary cylinder 4 will also rotate at the bottom of the confluence cylinder 2, driving the second filtrate tray 9 inside it to rotate. The diameters of the leakage grooves formed on the surfaces of the first filtrate tray 8 and the second filtrate tray 9 are different. During this rotation process, the area of their connection is adjusted, so as to adjust the amount of shunted polishing liquid. The anti - overflow cover 16 increases the area of shielding for the polishing liquid, avoiding the spraying of the polishing liquid into the external environment.

[0024] Embodiment 2:

[0025] On the basis of Embodiment 1, as Figure 1and Figure 4 As shown, a plurality of scraping bars 18 are provided at the top ends of the plurality of straight plates 17. The opening diameters of the plurality of overflow prevention covers 16 are all larger than the opening diameters of the plurality of storage cylinders 15. Two L-shaped plates 7 are fixedly installed inside the flow collecting cylinder 2. A first filter plate 8 is provided at the bottom ends of the two L-shaped plates 7. The bottom surface of the first filter plate 8 is in contact with the surface of the second filter plate 9. In a shunt device for detecting the concentration of polishing liquid according to the present invention, by providing a shelving frame 14, straight plates 17, scraping bars 18 and L-shaped plates 7, the storage cylinder 15 can be pulled out from the inside of the shelving frame 14. During the rotation of the transmission rod 11, the plurality of shelving frames 14 move in a circular motion, and the tops of the plurality of scraping bars 18 respectively rub against the bottoms of the plurality of shunt pipes 5.

[0026] Working principle: The shunt device used to detect the concentration of the polishing liquid is usually designed as a fluid mixing and separation system for shunting the sample flow and the detection flow. The shunt device can mainly shunt and inject the polishing liquid. Subsequently, using a conductivity meter, the sensor is immersed in the polishing liquid to measure the conductivity. According to the standard solution with a known solute concentration, the relationship between the conductivity and the concentration is established to determine the concentration of the polishing liquid. One end of the diversion pipe 3 can be connected to other pipe fittings, adjusting the distance for collecting the polishing liquid. The polishing liquid is gradually sucked into the interior of the diversion pipe 3 through the pump body, and then sent to the interior of the flow collecting cylinder 2 through one end of the diversion pipe 3 for centralized collection. Then, it is shunted and injected into the interiors of multiple storage cylinders 15 through several shunt pipes 5. After starting the micro-motor 10, first, the driving rod 11 connected to its output shaft in a transmission manner is driven to rotate. The shelving frame 14 is fixed to one end of the driving rod 11. The multiple shelving frames 14 rotate along with the rotation of the driving rod 11, so that the polishing liquid can be injected into the multiple storage cylinders 15 simultaneously. The design of the multiple storage cylinders 15 increases the working stations for shunt storage of the polishing liquid, improving the efficiency of the shunt device. Since the first gear 12 and the second gear 13 are meshed and connected, after the driving rod 11 rotates, the auxiliary cylinder 4 will also rotate at the bottom of the flow collecting cylinder 2, driving the second filter plate 9 inside it to rotate. The flow collecting cylinder 2 is stationary. The first filter plate 8 is connected to the flow collecting cylinder 2 by relying on two L-shaped plates 7, so the first filter plate 8 is also stationary. The diameters of the leakage grooves formed on the surfaces of the first filter plate 8 and the second filter plate 9 are different. During this rotation process, the area of their connection is adjusted, so that the amount of shunted polishing liquid can be adjusted. When the connection area is larger, the amount of polishing liquid flowing downward is more, and thus the injected amount is more. After the storage cylinder 15 stores the polishing liquid, the conductivity meter can be used to detect the concentration of the polishing liquid. The anti-overflow cover 16 increases the area for shielding the polishing liquid, preventing the polishing liquid from spraying into the external environment. The storage cylinder 15 can be pulled out from the interior of the shelving frame 14. During the rotation of the driving rod 11, the multiple shelving frames 14 perform circular motion. The tops of several scraping strips 18 respectively rub against the bottoms of several shunt pipes 5. The tops of the several scraping strips 18 are made of absorbent cotton, and the absorbent cotton wipes the polishing liquid on the bottom surface of the shunt pipe 5, preventing the polishing liquid from flowing onto the ground. One side of the straight plate 17 is clamped with one side of the shelving frame 14, and the two can be disassembled for easy replacement and cleaning of the scraping strip 18.
