DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0024] Please refer to Figure 1 The secondary separator for electrolytic copper production provided in the present application comprises a separation tank 01 having a liquid inlet 02 at the top and a liquid outlet 03 at the bottom; a multi-layer filter 05 arranged in the separation tank 01 for filtering and separating particulate matter; positive and negative electrodes 09 arranged below the multi-layer filter 05 for separating adsorbed colloidal substances and metal ions; the anode 10 in the positive and negative electrodes is an inert electrode that does not react with the electrolyte, the cathode 11 in the positive and negative electrodes is a metal electrode, and the selected positive and negative electrodes 09 are all single materials; the positive and negative electrodes 09 are further connected with a voltage stabilizer 12 for stabilizing the voltage within a fixed range; a cleaning mechanism 18 having a cleaning element 07 arranged on the surface of the multi-layer filter 05 for cleaning the surface of the filter; a rotating shaft 06 made of insulating material for mounting the cleaning element 07, and a driver 08 for driving the rotating shaft 06 and the cleaning element 07 to rotate.

[0025] It can be understood that the multi-layer filter 05 is a component for filtering fine substances in the electrolyte, and the filter hole diameter of the multi-layer filter 05 decreases from top to bottom layer by layer, and the filtering precision increases layer by layer. For example, the multi-layer filter 05 can be a single filter sheet composed of multiple filtering materials, the single filter sheet contains multiple layers of filter screens, each layer of filter screen is made of different materials, and the single filter sheet can also be a single-layer filter screen made of a single filtering material, and multiple single-layer filter screens are arranged in the separator, but not limited thereto. The cathode and anode 09 separate metal ions in the electrolyte by electrolytic reaction, and separate colloidal substances in the electrolyte by electrophoresis effect. Since the anode 10 is usually used to provide a metal ion source in the electrolytic reaction, in order to avoid the oxidation reaction of the metal on the anode 10, new metal ions enter the electrolyte, so the material of the anode 10 should be selected to be an inert material that does not undergo an electrochemical reaction, for example, it can be graphite, platinum, etc., but not limited thereto. The metal ions will be reduced to solid metal on the surface of the cathode 11 by gaining electrons, for example, it can be stainless steel, platinum, etc., but not limited thereto. After the electrolysis process is completed, the cathode and anode 09 contain reduced metals and absorbed colloidal substances on the surface, so the cathode and anode 09 can be detached and replaced, for example, it can be installed by screws, or it can be installed by rotating and tightening, etc., but not limited thereto. During the separation process, the voltage size affects the separation speed of colloidal substances and metal ions, so it is necessary to control the voltage within a certain range, for example, it can be a voltage stabilizer 12, or a transformer, etc., but not limited thereto. Since the voltage stabilizer 12 can set the voltage range, it is preferred to use the voltage stabilizer 12. The cleaning element 07 is used to automatically clean the surface of the filter element, for example, it can be an automatic scraping mechanism, or a washing machine that sprays the filter element surface, etc., but not limited thereto.

[0026] As can be seen from the above, the secondary separator for electrolytic copper production provided by the present application has a multi-layer filter 05 and a cathode and anode 09 in the separator. When the electrolyte is injected into the separator, the electrolyte is first filtered by the multi-layer filter 05, and then the electrolyte flows into the cathode and anode 09. The voltage range of the cathode and anode 09 is set on the voltage stabilizer 12, and the cathode and anode 09 are powered. The multi-layer filter 05 can filter fine particles in the electrolyte, the cathode and anode 09 can separate colloidal substances and metal ions in the electrolyte, and high-precision separation of impurities in the electrolyte is achieved.

[0027] Optionally, in some embodiments, referring to Figure 1 , the separator further has a flow guide plate 04 arranged on the top of the separation tank 01 and below the water inlet, for uniformly entering the electrolyte into the separation tank 01.

[0028] It can be understood that the flow guide plate 04 is a component for distributing the electrolyte, for example, it can be a shower head, or a disc distributor, etc., but not limited thereto.

[0029] In this way, the electrolyte can flow uniformly to the surface of the multi-layer filter 05, improving the filtering efficiency.

[0030] Optionally, in some embodiments, referring to Figure 1 , the multi-layer filter 05 includes a coarse filter layer 15 for removing large particulate impurities in the electrolyte, a medium filter layer 16 for removing small impurities in the electrolyte, and a fine filter layer 17 for removing extremely small impurities in the electrolyte.

[0031] It can be understood that the multi-layer filter 05 is a component with increasingly high filtering precision, for example, the coarse filter layer 15, the medium filter layer 16, and the fine filter layer 17 in the multi-layer filter 05 can be metal filter layers, fiber filter layers, and ultrafiltration membrane filter layers, or polypropylene fiber filter layers, activated carbon fiber layers, and ceramic membrane filter layers, but are not limited thereto.

[0032] In this way, the multi-layer filter 05 filters layer by layer, and as the electrolyte flows downward, the filtering precision of the filter layer becomes higher and higher, improving the ability to purify the electrolyte.

[0033] Optionally, in some embodiments, referring to Figure 1 and Figure 4 , the cathode and anode electrodes 09 are opposite and parallel; the lines of the cathode and anode electrodes 09 penetrate the separation tank 01 and are connected to the voltage stabilizer 12 installed outside the separation tank 01. The surface of the cathode and anode electrodes 09 is provided with a translucent film 19 for collecting colloidal substances.

[0034] It can be understood that the voltage stabilizer 12 is on the line of the cathode and anode electrodes 09, and is used to stabilize the voltage of the cathode and anode electrodes 09. The translucent film 19 is provided on the surface of the cathode and anode electrodes 09, and is used to collect colloidal substances gathered to the cathode and anode electrodes 09, while metal ions can pass through the translucent film 19 to the surface of the cathode 11 and be reduced to metal on the surface of the cathode 11.

[0035] In this way, colloidal substances and metal impurities can be treated separately, improving the treatment efficiency.

[0036] As can be seen from the above, the liquid inlet is opened, the electrolyte flows onto the deflector, is divided by the deflector, and then passes through the three-layer filter. When the electrolyte reaches the cathode and anode electrodes, the liquid inlet is closed, the voltage is set in the voltage stabilizer, the circuit of the cathode and anode electrodes is connected, and the cathode and anode electrodes start to separate colloidal substances and metal ions in the electrolyte. After the separation is completed, the circuit is closed, the liquid outlet is opened to guide the separated electrolyte out, and after the electrolyte is completely guided out, the cleaning device is opened to clean the surface of the filter.

[0037] The above merely describes a preferred embodiment of the present application; the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the scope of protection of the present application.
