During the copper foil production process, electrolyte purification is a crucial step, which directly affects the quality and production efficiency of copper foils.
[0003] Existing electrolyte purification devices mostly rely on chemical purification methods, using motors to drive stirring devices to promote the mixing of electrolytes and precipitants to achieve the purification purpose. However, during daily use, some problems still emerge. The position of the stirring device is fixed and the mode is single, which limits the mixing range, resulting in insufficient reaction in local areas, insufficient contact between impurities in the electrolyte and the precipitant, and reduced reaction efficiency. In addition, this traditional process relies on subsequent precipitation steps to separate the purified liquid from the precipitate, and this link is inefficient, resulting in discontinuous purification processes.

An annular wave groove is arranged at the upper end of the inner arc surface of the purification tank. Transversely symmetrically distributed connecting rods are arranged at the upper end of the outer arc surface of the purification tank. The outer spherical heads of the connecting rods are all slidably connected with the annular wave groove. A first motor is arranged at the middle part of the upper end surface of the purification tank, and the lower end of the output shaft of the first motor is fixedly connected with the upper end of the rotating cylinder. The solenoid valve and the first motor are both electrically connected to an external single-chip microcomputer. A filtering component is also arranged at the upper end of the filtering box, and a solid-liquid separation component is arranged at the upper end of the right surface of the filtering box.
[0006] The purification mechanism further includes annular plates symmetrically arranged vertically at the lower end of the outer arc surface of the stirring rod.
[0007] The filtering assembly includes filter plates symmetrically arranged vertically at the upper end of the inner cavity of the filtering box. Discharge ports corresponding to the filter plates one by one are provided at the upper end of the right surface of the filtering box. The filtering assembly further includes electric telescopic rods symmetrically arranged vertically at the upper end of the left surface of the filtering box.

[0008] The solid-liquid separation assembly includes a fixed cover provided at the upper end of the right surface of the filtering box.

[0009] The beneficial effects of the above technical solutions of the present utility model are as follows:
[0010] 1. First, relevant staff feed an appropriate amount of electrolyte to be purified into the purification tank, and then select a suitable precipitant according to the types and concentrations of impurities in the electrolyte and add it to the purification tank. Then, relevant staff control the operation of the first motor through an external single-chip microcomputer. The rotation of the output shaft of the first motor drives the rotating cylinder, stirring rod, connecting rod and annular plate to rotate synchronously, so that the electrolyte and the precipitant added to the purifying agent are fully mixed and reacted. At the same time, when the connecting rod rotates, it drives the stirring rod and the annular plate to move up and down through the annular wave groove, thereby changing the stirring depth of the stirring rod. At the same time, when the annular plate moves up and down, it will intensify the turbulence of the electrolyte, ensuring that the precipitant fully contacts and efficiently reacts with the impurity ions in the electrolyte, and realizing a three-dimensional stirring effect.
[0011] 2. When the impurities in the electrolyte react completely with the precipitant to form insoluble precipitates, the relevant staff adjust and control the solenoid valve to open through an external single-chip microcomputer. The preliminarily purified electrolyte carrying the precipitates flows through the liquid outlet pipe into the filter box. The electrolyte mixture entering the filter box will pass through two filter plates in sequence for more refined filtration, so that the precipitates in the electrolyte mixture will remain on the filter surface of the filter plates. At the same time, the relevant staff adjust and control the electric telescopic rod to operate reciprocally synchronously through the external single-chip microcomputer. When the telescopic end of the electric telescopic rod extends, it drives the rectangular plate, the sliding scraper, the second motor and the lead screw to extend synchronously, so that the sliding scraper scrapes off the precipitates remaining on the filter surfaces of the two filter plates, and finally discharges them through the discharge port. When the telescopic end of the electric telescopic rod retracts, the external single-chip microcomputer controls the second motor to operate. The output shaft of the second motor moves to drive the lead screw to rotate synchronously. When the lead screw rotates, the sliding scraper moves upward, so that the sliding scraper is separated from the filter plate, avoiding scraping the precipitates when the sliding scraper resets, thus being able to continuously maintain the filtration efficiency and avoid the situation that the filter holes are blocked by precipitates resulting in the failure of the filter plate to filter, solving the problem that the existing method needs to precipitate in a sedimentation tank to separate the electrolyte and the precipitates, and the whole process is continuous and efficient, greatly improving the efficiency of electrolyte purification.
[0012] 3. The precipitates discharged from the discharge port and part of the purified electrolyte will fall into the filter plate box. Among them, the purified electrolyte is separated from the precipitates through the filter plate box. Finally, the purified electrolyte flows back into the filter box through the purified electrolyte, realizing the effective separation of the electrolyte and the precipitates. Then, the relevant staff only need to regularly pull out the filter plate box for cleaning. Description of the Drawings

[0021] As Figures 1-4As shown in the figure, the filtering component includes filter plates 300 symmetrically arranged vertically at the upper end of the inner cavity of the filtering box 100. A discharge port 301 corresponding to each filter plate 300 is provided at the upper end of the right surface of the filtering box 100. The filtering component also includes electric telescopic rods 302 symmetrically arranged vertically at the upper end of the left surface of the filtering box 100. The telescopic ends of the electric telescopic rods 302 respectively pass through the through holes provided at the upper end of the left wall surface of the filtering box 100 and extend into the filtering box 100. Rectangular plates 303 are provided at the inner end heads of the telescopic ends of the electric telescopic rods 302. Sliding scrapers 304 are slidably connected to the grooves provided on the lower surfaces of the electric telescopic rods 302.

The electric telescopic rods 302 are all electrically connected to an external single-chip microcomputer. The filtering component also includes a second motor 305 provided in the middle of the top wall surface of the groove.

The second motors 305 are all electrically connected to an external single-chip microcomputer. The diameters of the filter holes of the two filter plates 300 and the filter plate box 401 gradually decrease from top to bottom.
[0022] The working principle of an electrolyte purification device provided by the utility model is as follows: First, relevant staff feed an appropriate amount of electrolyte to be purified into the purification tank 200. Then, according to the types and concentrations of impurities in the electrolyte, a suitable precipitant is selected and added to the purification tank 200. Then, relevant staff regulate the operation of the first motor 207 through an external single-chip microcomputer. The output shaft of the first motor 207 rotates to drive the rotating cylinder 203, the stirring rod 204, the connecting rod 206, and the annular plate 208 to rotate synchronously, so that the electrolyte and the precipitant added as the purification agent are fully mixed and reacted. At the same time, when the connecting rod 206 rotates, it drives the stirring rod 204 and the annular plate 208 to move up and down through the annular wave groove 205, thereby changing the stirring depth of the stirring rod 204. At the same time, when the annular plate 208 moves up and down, it will intensify the turbulence of the electrolyte, ensuring that the precipitant is in full contact with the impurity ions in the electrolyte and reacting efficiently, achieving a three-dimensional stirring effect. When the impurities in the electrolyte completely react with the precipitant to form insoluble precipitates, relevant staff regulate the solenoid valve 202 to open through an external single-chip microcomputer. The preliminarily purified electrolyte carrying the precipitate flows through the liquid outlet pipe 201 into the filter box 100. The electrolyte mixture entering the filter box 100 will be more finely filtered through two filter plates 300 in sequence, so that the precipitate in the electrolyte mixture stays on the filter surface of the filter plate 300. At the same time, relevant staff regulate the synchronous reciprocating operation of the electric telescopic rod 302 through an external single-chip microcomputer. When the telescopic end of the electric telescopic rod 302 extends, it drives the rectangular plate 303, the sliding scraper 304, the second motor 305, and the lead screw 306 to extend synchronously, so that the sliding scraper 304 scrapes off the precipitate staying on the filter surfaces of the two filter plates 300 and finally discharges it through the discharge port 301. When the telescopic end of the electric telescopic rod 302 retracts, the external single-chip microcomputer regulates the operation of the second motor 305. The output shaft of the second motor 305 moves to drive the lead screw 306 to rotate synchronously. When the lead screw 306 rotates, the sliding scraper 304 moves up, so that the sliding scraper 304 is separated from the filter plate 300, avoiding the sliding scraper 304 scraping the precipitate during the reset process, thereby being able to continuously maintain the filtering efficiency and avoiding the problem of the filter plate 300 failing to filter due to the precipitate blocking the filter holes. It solves the problem of the existing need to separate the electrolyte and the precipitate through sedimentation in a sedimentation tank, and the whole process is continuous and efficient, greatly improving the efficiency of electrolyte purification.
[0023] Such as Figures 1-2As shown in the figure, the solid-liquid separation component includes a fixed cover 400 arranged at the upper end of the right surface of the filtration tank 100. A filter plate box 401 is slidably connected to the opening arranged at the lower end of the front surface of the fixed cover 400. A transfer pipe 402 is provided between the circular hole arranged in the middle of the lower surface of the fixed cover 400 and the through hole arranged at the lower end of the right surface of the filtration tank 100. The discharge ports 301 are all located inside the fixed cover 400. The precipitates discharged from the discharge ports 301 and part of the purified electrolyte will fall into the filter plate box 401. Among them, the purified electrolyte passes through the filter plate box 401 to be separated from the precipitates. Finally, the purified electrolyte flows back into the filtration tank 100 through the purified electrolyte, realizing the effective separation of the electrolyte and the precipitates. Then, the relevant staff only need to regularly pull out the filter plate box 401 for cleaning.
