[0002] Electrochemical machining (ECM) is a processing method that removes metallic materials through electrochemical reactions. Its basic principle is based on electrolysis, where an electric current in an electrolyte causes a redox reaction on the workpiece surface, thereby removing the metal. During ECM, the workpiece and electrodes are connected by an electrolyte; as the current flows, the metal surface is electrolyzed into ions and dissolved, forming tiny metal particles, thus achieving material removal.

[0003] In existing processing technology, even after preliminary filtration, the electrolyte still contains many insoluble micro-impurities and soluble metal ions. If it is to be recycled, the electrolyte needs to be purified to remove the soluble target metal ions and micro-impurities. Existing equipment usually has a sedimentation tank to separate insoluble impurities, but after long-term use, the precipitated impurities accumulate at the bottom of the tank and are inconvenient to discharge.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1:

[0027] This embodiment provides an electrolyte recovery and purification device for metal electrolytic cutting, specifically as follows: Figures 1-2 As shown, it includes a purification tank, which is equipped with a precipitation chamber and a purification group. The precipitation chamber is used to temporarily store the electrolyte, and the purification group is used to purify the electrolyte.

[0028] The purification box is equipped with a base plate 107, a collection trough 111, and a baffle 119, forming the sedimentation chamber. The baffle 119 is connected to the base plate 107 and the collection trough 111 respectively. An inclined guide plate is installed in the sedimentation chamber. The purification box is provided with an inlet 103 and a discharge port 104, both of which are connected to the sedimentation chamber. A valve is installed on the discharge port 104. The collection trough 111 is provided with a discharge hole, which is connected to the purification group. The purification box is provided with an outlet 105, which is connected to the purification group.

[0029] After the electrolyte is slowly introduced into the sedimentation chamber from the inlet 103 with a certain hydraulic pressure, the electrolyte remains in the sedimentation chamber until the liquid level of the electrolyte in the sedimentation chamber is higher than the top of the baffle 119. At this time, the electrolyte in the sedimentation chamber flows to the collecting tank 111 and flows into the purification group from the discharge hole on the collecting tank 111. After being purified by the purification group, it is discharged from the outlet 105.

[0030] Based on the above process, the state of the electrolyte in the precipitation chamber is further analyzed: when the electrolyte flows into the precipitation chamber, it... Figure 2 For example, the electrolyte flows slowly from left to right. During the flow, some insoluble impurities in the electrolyte begin to slowly sink onto the guide plate. The electrolyte flowing from the top of the baffle 119 to the collecting tank 111 is the relatively clean upper layer. Through the sedimentation step, most of the insoluble impurities in the electrolyte can be separated. Due to the inclination of the guide plate, these insoluble impurities will slide towards the lower end of the guide plate under the action of gravity and then collect in the sedimentation chamber near the discharge port 104. After a period of use, the valve on the discharge port 104 is opened, and these insoluble impurities will be discharged from the discharge port 104, achieving periodic cleaning.

[0031] By setting up a guide plate and a baffle 119 together, insoluble impurities in the electrolyte can be separated, which is simple in structure, low in cost and convenient for impurity discharge.

[0032] Example 2:

[0033] This embodiment further extends the above embodiment, specifically as follows: Figures 2-4 As shown, a vibration unit 109 is installed on the guide plate. The vibration unit 109 is used to make the vibrating plate 108 vibrate. In this embodiment, the vibration unit 109 is a vibration motor. The vibration motor makes the vibrating plate 108 vibrate slightly, so that the impurities accumulated on the guide plate can slide down to the impurity discharge port 104, which facilitates the cleaning operation.

[0034] Furthermore, the guide plate includes a mounting frame 114, a shock-absorbing sealing ring 115, and a vibrating plate 108. The vibrating plate 108 is mounted on the shock-absorbing sealing ring 115, which is mounted on the mounting frame 114. The mounting frame 114 is mounted on the base plate 107, and the vibration unit 109 is connected to the vibrating plate 108. The shock-absorbing sealing ring 115 significantly reduces the vibration transmitted from the vibrating plate 108 to the mounting frame 114, ensuring that when the vibration unit 109 guides impurities, the vibration of the vibrating plate 108 is not further transmitted to the mounting frame 114 and the purification chamber, thereby reducing the overall vibration of the purification chamber.

[0035] Furthermore, an elastic element 110 is installed on the base plate 107. The elastic element 110 is used to support the vibrating plate 108. In this embodiment, the elastic element 110 is a spring. Since the vibrating plate 108 is not rigidly connected to the mounting frame 114, in order to prevent excessive displacement of the vibrating plate 108 due to hydraulic pressure, which would cause leakage between the shock-absorbing sealing ring 115 and the mounting frame 114 and the vibrating plate 108, a spring is used to support the bottom of the vibrating plate 108. This setting does not affect the vibration of the vibrating plate 108, but it can prevent the vibrating plate 108 from excessive displacement.

[0036] Furthermore, a flow-damping shroud 118 is installed on the sedimentation chamber, covering the inlet 103. The flow-damping shroud 118 blocks the electrolyte flowing at the inlet 103, thereby slowing down the flow rate and preventing it from overturning the impurities deposited on the vibrating plate 108, thus maintaining a low-speed flow of the electrolyte in the sedimentation chamber.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0038] Example 3:

[0039] This embodiment further extends the above embodiment. Specifically, as shown in the purification group, the purification group includes a drain pipe 116, an inlet pipe 117, and a resin separation column 112. The inlet pipe 117 is connected to the discharge hole and the input end of the resin separation column 112, respectively. The drain pipe 116 is connected to the output end of the resin separation column 112 and the outlet 105, respectively, and the outlet 105 is higher than the resin separation column 112.

[0040] The electrolyte at the collecting tank 111 flows into the resin separation column 112 through the inlet pipe 117. Because the sedimentation chamber is airtight and the electrolyte flowing in through the inlet 103 is hydraulically pressurized, the electrolyte can quickly pass through the resin separation column 112 under hydraulic pressure. It then flows from the drain pipe 116 to the outlet 105 and finally out of the outlet. The resin separation column 112 can adsorb and separate soluble target metal ions in the electrolyte, thus purifying the electrolyte.

[0041] Furthermore, the purification box is also provided with a clamp 113 for supporting and fixing the resin separation column 112; the clamp 113 includes an upper clamping arc 1131, a lower clamping arc 1132, and a fastening bolt 1133. The upper clamping arc 1131 and the lower clamping arc 1132 are rotatably connected, and the fastening bolt 1133 is used to tighten the upper clamping arc 1131 and the lower clamping arc 1132 to fix the resin separation column 112.

[0042] The resin separation column 112 is supported and limited by the clamp 113 to prevent it from shaking. When disassembling, first loosen the clamp 113. At this time, the upper clamp arc 1131 and the lower clamp arc 1132 no longer clamp the resin separation column 112. Then, move the clamp 113 laterally to both sides of the resin separation column 112. At this time, loosen the connection between the resin separation column 112 and the drain pipe 116 and the inlet pipe 117. Replace the resin separation column 112 with a new one. Then connect the new resin separation column 112 to the drain pipe 116 and the inlet pipe 117. Then move the clamp 113 back to its original position so that the upper clamp arc 1131 and the lower clamp arc 1132 are fitted onto the resin separation column 112. Tighten the fastening bolt 1133. At this time, the clamp 113 will support and limit the resin separation column 112 again.

[0043] Furthermore, the purification chamber includes a chamber body 101, a chamber cover 102, and a replacement window baffle 106. Both the chamber body 101 and the replacement window baffle 106 are detachably connected to the chamber cover 102, and the chamber body 101 and the chamber cover 102 are sealed together. The chamber cover 102 is provided for the installation of parts in the sedimentation chamber, while the replacement window baffle 106 is provided to facilitate the disassembly and assembly of the resin separation column 112.

[0044] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
