Abstract
Description
Technical Field
[0001] This application relates to the field of hydrometallurgical technology, and in particular to a leakage prevention device for an electrolysis system. Background Technology
[0002] Electrolysis or electrowinning are important methods in hydrometallurgy, both of which utilize electrolytic cells. These cells contain an electrolyte, an anode plate, and a cathode plate. In the hydrometallurgical process, a leaching agent dissolves valuable metal components from ores, concentrates, roasted sand, and other materials in a solution. Direct current passes sequentially through the anode plate, the electrolyte, and the cathode plate. The valuable metals ultimately precipitate as a new solid phase at the cathode plate, thus achieving metal separation, enrichment, and extraction.
[0003] Electrolysis and electrowinning both require continuous recycling of the electrolyte. After electrolysis or electrowinning, the electrolyte flows out of the electrolytic cell, passes through a sluice and mixing tank to replenish metal ions, and is then pumped back into the electrolytic cell for use. During this process, the equipment occupies a significant amount of wiring and is in contact with the ground. Over long-term use, the internal and external walls of the equipment develop current channels connected to the ground, resulting in current loss and energy waste during electrolysis or electrowinning.
[0004] Therefore, this application proposes an anti-leakage device for an electrolysis system, which can disconnect the electrolyte discharged into the electrolyte circulation facility from the electrolyte in the electrolysis tank, thereby preventing the formation of a current channel between the electrolyte discharged from the electrolysis tank and the ground, which would result in current loss and energy waste. Utility Model Content
[0005] The main purpose of this application is to provide a leakage prevention device for an electrolysis system, which aims to solve the technical problem of current loss and energy waste caused by the current channel between the electrolyte and the ground.
[0006] To achieve the above objectives, this application provides the following technical solution:
[0007] Electrolytic cells are used in hydrometallurgy.
[0008] At least two buffer pools are used to buffer the electrolyte;
[0009] The pipeline assembly includes a first conduit and a second conduit. The output end of the electrolytic cell is connected to the input end of each buffer tank through the first conduit. The output end of each buffer tank is connected to the electrolyte circulation facility through the second conduit. The on / off state of each first conduit and each second conduit is controlled respectively to discharge the electrolyte in the electrolytic cell and to disconnect the electrolyte in the electrolytic cell from the discharged electrolyte.
[0010] As a further improvement of this application, the pipeline assembly further includes a first pipeline valve and a second pipeline valve. Each first conduit is provided with a first pipeline valve, and each second conduit is provided with a second pipeline valve. The on / off state of each first pipeline valve and each second pipeline valve is controlled respectively to control the on / off state of each first conduit and each second conduit.
[0011] As a further improvement of this application, the pipeline assembly also includes a pump body, with each second conduit equipped with a pump body, and each pump body is controlled to perform work to extract electrolyte from the buffer tank that is disconnected from the electrolytic cell.
[0012] As a further improvement of this application, the pipeline assembly also includes a level gauge, with one level gauge installed in each buffer to detect the actual liquid level in each buffer pool.
[0013] The technical solution provided in this application may include the following beneficial effects:
[0014] During use, the electrolytic cell continuously discharges electrolyte. By controlling the opening / closing of each first pipeline valve, the flow of electrolyte from the electrolytic cell into a buffer tank is controlled. Once the buffer tank is full, the electrolyte continues to flow into subsequent electrolytic cells. Simultaneously, the opening / closing of each second pipeline valve and the corresponding pump are controlled to pump the electrolyte from the buffer tank (which is disconnected from the electrolytic cell) to the electrolyte circulation system. This prevents the formation of a current path between the electrolyte in the electrolytic cell and the ground during discharge, thus avoiding current loss and energy waste.

[0026] Figure 1 An embodiment of an anti-leakage device for an electrolysis system according to this application is shown; see [link to relevant documentation]. Figure 1 In this embodiment, the leakage prevention device of the electrolysis system includes: an electrolytic cell 1, at least two buffer pools 2, and a pipeline assembly.
[0027] Among them, see Figure 1 The pipeline assembly includes a first conduit 3 and a second conduit 4. The output end of the electrolytic cell 1 is connected to the input end of each buffer tank 2 via the first conduit 3. Each buffer tank is connected to the electrolyte circulation facility via the second conduit 4. Electrolyte continuously flows out of the electrolytic cell 1. The opening / closing of each first pipeline valve 5 is controlled to control the opening / closing of each first conduit 3, allowing the electrolyte flowing out of the electrolytic cell 1 to flow into one of the buffer tanks 2. When the buffer tank 2 is full of electrolyte, the electrolyte in the electrolytic cell 1 continues to flow into the subsequent buffer tank 2. At the same time, the opening / closing of each second pipeline valve 6 is controlled, and the corresponding pump 7 performs work to pump the electrolyte in the buffer tank 2 that is disconnected from the electrolyte in the electrolytic cell 1 to the electrolyte circulation facility, avoiding the formation of a current channel between the electrolyte in the electrolytic cell 1 and the ground when the electrolyte is discharged, thus preventing current loss and energy waste.
[0028] It should be noted that there is a certain distance between the electrolytic cell 1 and the electrolyte circulation facility. The electrolyte discharge pipe may have a part that is in contact with the ground or close to the ground. The discharge of electrolyte from the electrolytic cell 1 is a continuous process, which makes the electrolyte in the discharge pipe and the electrolyte in the electrolytic cell 1 a short circuit. This makes it easy for the electrolyte to form a current channel with the ground during the discharge process. The leakage prevention structure provided in this embodiment separates the electrolyte extraction and discharge processes in the electrolytic cell 1, and disconnects the discharged electrolyte from the electrolyte in the electrolytic cell 1, thus solving this problem.
[0029] Further, see Figure 1 The pipeline assembly also includes a first pipeline valve 5 and a second pipeline valve 6. Each first conduit 3 is provided with a first pipeline valve 5 and each second conduit 4 is provided with a second pipeline valve 6. The opening / closing of each first pipeline valve 5 and each second pipeline valve 6 are controlled respectively to control the on / off state of each first conduit 3 and each second conduit 4.
[0030] Optionally, both the first pipeline valve 5 and the second pipeline valve 6 are solenoid valves, so as to remotely control the opening / closing of each first pipeline valve 5 and each second pipeline valve 6.
[0031] It should be noted that each first pipeline valve 5 and each second pipeline valve 6 are initially in a closed state.
[0032] Further, see Figure 1 The pipeline assembly also includes a pump body 7. Each second conduit 4 is equipped with a pump body 7. The electrolyte flowing out of the electrolytic cell is continuously injected into one of the buffer tanks 2. When the buffer tank is full, it continues to flow into the subsequent buffer tanks. The pump body associated with the buffer tank 2 that has been filled with electrolyte is controlled to pump out the electrolyte in the buffer tank 2.
[0033] Further, see Figure 1 The pipeline assembly also includes a level gauge 8, with one level gauge 8 installed in each buffer pool 2 to detect the actual liquid level in each buffer pool 2.
[0034] It should be noted that this embodiment focuses on the working principle of the first pipeline valve 5, the second pipeline valve 6, the pump body 7, and the level gauge 8. The specific structure of the first pipeline valve 5, the second pipeline valve 6, the pump body 7, and the level gauge 8 is not the focus of this embodiment and is existing technology. This embodiment and the accompanying drawings have given the installation area or position of the first pipeline valve 5, the second pipeline valve 6, the pump body, and the level gauge 8, and the specific structure of the first pipeline valve 5, the second pipeline valve 6, the pump body, and the level gauge 8 will not be described in detail again.
[0035] Optionally, in this embodiment, setting two electric buffer pools 2 is the best embodiment. Correspondingly, there are two first conduits 3, two second conduits 4, one first pipeline valve 5, one second pipeline valve 6, and one pump body 7.
[0036] For example, consider two buffer tanks, Buffer Tank I and Buffer Tank II. Correspondingly, there are two first conduits, First Conduit I and First Conduit II; two second conduits, Second Conduit I and Second Conduit II; two first pipeline valves, First Pipeline Valve I and First Pipeline Valve II; two second pipeline valves, Second Pipeline Valve I and Second Pipeline Valve II; and two pump bodies, Pump Body I and Pump Body II. The working principle of the leakage protection device for this electrolysis system is as follows:
[0037] Step S1: Control the first pipeline valve I to open, and control the first pipeline valve II, the second pipeline valve I, the second pipeline valve II, the pump body I and the pump body II to close, so that the internal electrolyte will be continuously input into the buffer tank I until the buffer tank I is full of electrolyte;
[0038] Step S2: Control the opening of the first pipeline valve II, the second pipeline valve I and the pump body I, and control the opening of the first pipeline valve I, the pipeline valve II and the pump body II to continuously input the electrolyte in the electrolytic cell into the buffer tank II, while draining the electrolyte in the buffer tank I into the electrolyte circulation facility until the buffer tank II is full of electrolyte;
[0039] Step S3: Repeat the above steps in sequence.
[0040] In this embodiment, electrolyte continuously flows out of the electrolytic cell 1. By controlling the opening / closing of each first pipe valve 5, the on / off state of each first conduit 3 is controlled, allowing the electrolyte flowing out of the electrolytic cell 1 to be injected into one of the buffer tanks 2. When the buffer tank 2 is full of electrolyte, it continues to be fed into the subsequent buffer tank 2. At the same time, the opening / closing of each second pipe valve 6 is controlled, the on / off state of each second conduit 4 is controlled, and the corresponding pump body 7 is controlled to perform work to pump the electrolyte that is disconnected from the electrolyte in the buffer tank 2 to the electrolyte circulation facility, so as to avoid the formation of a current channel between the electrolyte in the electrolytic cell 1 and the ground when the electrolyte is discharged, which would cause current loss and energy waste.
[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
