[0024] Pressure sensors are installed in the primary filter mechanism 7 and the fine filter 11, and the pressure sensors are connected to the master controller 17 by signal.

[0026] It should be noted that: in this embodiment, the filter 103 is detachably arranged in the diamond abrasive recovery tank 1.

[0027] Example 2

[0028] Reference Figure 2 The diamond wire saw electroplating liquid purification treatment device of this embodiment has the following differences compared with the embodiment 1:

[0029] An ultrasonic generator 18 is provided on the side wall of the diamond abrasive recovery tank 1 where the filter screen 103 is provided. The ultrasonic wave generated by the ultrasonic generator 18 is used to enhance the movement of the fluid in the diamond abrasive recovery tank 1, thereby improving the filtering efficiency. When the impurities attached to the diamond abrasive are flushed through the flushing water inlet pipe 105, it is beneficial to remove the impurities from the surface of the diamond abrasive. Then, the diamond abrasive is further separated from the impurities due to its large density and the small density of impurities, which makes it easy to float horizontally and overflow from the impurity discharge port 101, thereby efficiently recovering the diamond abrasive and reducing the loss of the diamond abrasive in the electroplating process.

[0030] The liquid inlet pipe 102 is connected to the liquid discharge pipe 104 of the diamond wire saw electroplating device 19 through a pipeline, and the electroplating liquid discharge port 1301 is connected to the liquid inlet pipe 102 of the diamond wire saw electroplating device 19 or the electroplating liquid storage tank 20 through a pipeline. Compared with the existing manual transfer of electroplating liquid to the electroplating liquid treatment tank for treatment, the use, purification and storage of the electroplating liquid are realized by using the pipeline, which reduces the transfer work intensity during the purification process of the diamond wire saw electroplating liquid.

[0031] Working principle and usage of this utility model:

[0032] The filter screen 103 in the diamond abrasive recovery tank 1 can not only filter and separate large-size impurities and diamond abrasives in the electroplating solution to improve the subsequent electrolytic purification efficiency, but also can use the flushing water inlet pipe 105 to further separate large-size impurities and diamond abrasives, so as to facilitate the recycling of diamond abrasives; the pretreatment tank 2 uses the aeration pipe 4, the constant temperature heating pipe 5 and the activated carbon to perform primary adsorption and impurity removal treatment on the electroplating solution. The airflow generated by the aeration pipe 4 can promote the mixing and contact of the activated carbon and the electroplating solution, improve the adsorption efficiency, and also remove the oxygen dissolved in the electroplating solution to prevent the occurrence of oxidation reaction, so as to facilitate the improvement of the electrolytic treatment efficiency of the subsequent electrolytic tank 9 on the electroplating solution.

[0033] When in use, first open the solenoid valves on the liquid inlet pipe 102 and the liquid discharge pipe 104 through the main controller 17, add diamond wire saw electroplating liquid into the diamond abrasive recovery tank 1, and the electroplating liquid flows into the pretreatment tank 2 after being filtered by the filter 103. After the diamond wire saw electroplating liquid is completely filtered and flows into the pretreatment tank 2, close the solenoid valves on the liquid inlet pipe 102 and the liquid discharge pipe 104, and then open the solenoid valve and the ultrasonic generator 18 on the flushing water inlet pipe 105 through the main controller 17. As the liquid level in the diamond abrasive recovery tank 1 rises, the light impurities on the filter 103 are separated from the diamond abrasives under the action of buoyancy and ultrasonic waves, and the diamond abrasives are deposited on the filter 103, while the light large particles of impurities enter the impurity discharge port 101 and are discharged from the diamond abrasive recovery tank 1. At the same time, the flushing water can also clean the diamond abrasives. After washing, after the light large particle impurities are removed, the washing water is discharged from the diamond abrasive recovery tank 1 through the drain pipe 104, and then the diamond abrasives on the filter screen 103 are manually collected. Preferably, the filter screen 103 is detachably arranged in the diamond abrasive recovery tank 1. After washing, the filter screen 103 is taken out and the diamond abrasives are recovered, and then the filter screen 103 is washed; at the same time, the solenoid valve on the feeding pipe 601 is controlled to open by the main controller 17, and activated carbon is quantitatively added to the pretreatment tank 2. The plating solution flowing into the pretreatment tank 2 is heated by the constant temperature heating tube 5, and the airflow bursting from the aeration tube 4 drives the plating solution to flow, promotes the collision and adsorption between the plating solution and the activated carbon added to the pretreatment tank 2, further removes the tiny particle impurities in the plating solution, and removes the oxygen dissolved in the plating solution. The plating liquid treated by the pretreatment tank 2 is filtered again by the primary filtering mechanism 7 and then enters the electrolytic tank 9. The metal impurities in the plating liquid can be removed in the electrolytic tank 9. At the same time, the composition of the electrolyte in the purification tank 13 is monitored in real time by the plating liquid analyzer 12, and then the operation state of the dosing pump 14 is controlled by the main controller 17 to supplement the corresponding reagents. When the plating liquid analyzer 12 detects that the composition of the plating liquid in the purification tank 13 meets the requirements, the main controller 17 issues an instruction and the dosing pump 14 stops working, so that the composition of the plating liquid in the electrolytic tank 9 is more in line with the production requirements of diamond wire saw electroplating; the plating liquid after electrolysis in the plating tank is filtered by the fine filter 11 and enters the purification tank 13, and then flows into the diamond wire saw electroplating device 19 through the plating liquid discharge port 1301 for use or enters the plating liquid storage tank 20 for standby.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model are included in the protection scope of the utility model.
