Description

Technical Field

[0001] This utility model relates to the field of electrolytic production equipment technology, specifically to a continuous metal powder production device. Background Technology

[0002] In the electrolytic production of copper powder, a solution containing copper ions (such as copper sulfate solution) is used as the electrolyte. Pure copper is used as the anode and an inert material (such as stainless steel) is used as the cathode. After the DC power supply is turned on, the copper at the anode loses electrons and dissolves into copper ions, which enter the solution. The copper ions in the solution are deposited at the cathode. By controlling parameters such as electrolysis voltage, temperature, and electrolyte concentration, copper will be precipitated as powder at the cathode. Finally, copper powder can be obtained through washing, drying, and other processes. This method has the characteristics of high product purity and controllable particle size, and can be used in the fields of electronics and metallurgy.

[0003] Existing electrolysis production equipment places the filter membrane at the bottom or side of the electrolytic cell, close to the cathode area. As copper powder is continuously generated during electrolysis, and some fine particles flow with the electrolyte, the filter membrane needs to continuously filter the copper powder. The high filtration capacity and load-bearing weight make the filter membrane prone to clogging and damage, requiring frequent shutdowns for cleaning or replacement of the filter membrane, which affects the continuity of production. Utility Model Content

[0004] The purpose of this utility model is to provide a continuous metal powder production device in order to solve the above problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0009] The top of the collection tank is equipped with a filter membrane layer for filtering and separating metal powder and electrolyte.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The continuous production system composed of a high-level tank, an electrolytic cell, and a collection tank in this utility model realizes the continuous production of metal powder and the recycling of electrolyte, effectively improving the efficiency of electrolytic preparation.

[0021] 2. In this utility model, the filter membrane layer is placed at the top of the collection tank, so that the metal powder can be deposited at the bottom of the collection tank under the action of gravity. A small amount of metal powder moving with the electrolyte is filtered by the top filter membrane layer and is also deposited at the bottom due to gravity. This reduces the filtration volume of the filter membrane layer and reduces its load-bearing weight. At the same time, it avoids the membrane layer from being frequently blocked or damaged due to excessive load, thus ensuring the continuity and stability of production.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1-2 As shown, in one embodiment, a continuous metal powder production apparatus includes: a high-level tank 1, an electrolytic cell 2, and a collection tank 3.

[0029] The high-level tank 1 is connected to the electrolytic cell 2 via a pipeline, which is used to stably transport the electrolyte to the electrolytic cell 2 by using the kinetic energy generated by the liquid level difference; the electrolytic cell 2 is connected to the collection tank 3 via a pipeline, which is used to electrolyze and generate metal powder (which can be copper powder, etc. in this embodiment); the collection tank 3 is connected to the high-level tank 1 via a pipeline, which is used to separate the metal powder from the electrolyte, and then collect the metal powder and recycle the electrolyte.

[0030] Understandably, the continuous production system consisting of high-level tank 1, electrolytic cell 2 and collection tank 3 enables continuous production of metal powder, avoiding the time loss and efficiency reduction caused by frequent start-ups and shutdowns of equipment in traditional intermittent production. Furthermore, the recycling of electrolyte reduces raw material waste and further improves the overall efficiency of electrolytic preparation.

[0031] Furthermore, one side of the top of the high-level tank 1 is connected to the storage tank 15 via a liquid supply pipeline 5. A first control valve 6 is installed on the liquid supply pipeline 5. After production is completed, the first control valve 6 can be opened to replenish the electrolyte consumed during the electrolytic production of metal powder, ensuring that the total amount of electrolyte in the electrolytic cell 2 remains stable. Correspondingly, the other side of the top of the high-level tank 1 is connected to the top of the collection tank 3 via a recovery pipeline 7. A second control valve 8 and a recovery pump 9 are installed on the recovery pipeline 7. After sedimentation is completed, the second control valve 8 and the recovery pump 9 can be opened, and the filtered electrolyte can be driven by the recovery pump 9 to flow back into the high-level tank 1, realizing closed-loop recovery of electrolyte and reducing resource waste.

[0032] Furthermore, one side of the bottom of the electrolytic cell 2 is connected to the bottom of the high-level tank 1 through the inlet pipe 10, allowing the liquid to flow into the electrolytic cell 2 continuously and stably through the liquid level difference during production. Correspondingly, the other side of the bottom of the electrolytic cell 2 is connected to one side of the collection tank 3 through the outlet pipe 11, and a third control valve 12 is installed on the outlet pipe 11. During production, the second control valve 8 can be opened, so that the copper powder generated in the electrolytic cell 2 and scraped off from the cathode can flow into the collection tank 3 along with the electrolyte, ensuring that the copper powder leaves the electrolysis area in time and avoids accumulating in the electrolytic cell 2 and affecting the reaction.

[0033] Furthermore, the bottom of the collection tank 3 is connected to the receiving end through the discharge pipe 13, and a fourth control valve 14 is provided on the discharge pipe 13. When the copper powder in the collection tank 3 accumulates to a set amount, the fourth control valve 14 can be opened to continuously transport the collected metal powder to the collection end.

[0034] It should be noted that a filter membrane layer 4 is provided at the top of the collection tank 3 for filtering and separating metal powder and electrolyte.

[0035] Understandably, placing the filter membrane layer 4 at the top of the collection tank 3 allows the metal powder produced by electrolysis to naturally settle to the bottom of the collection tank 3 under gravity. A small amount of metal powder moving upward with the electrolyte can be intercepted by the filter membrane layer 4 at the top and gradually settle to the bottom under gravity. The filter membrane layer 4 does not need to bear the task of filtering a large amount of copper powder, but only plays a role in filtering a small amount of fine particles, which greatly reduces the filtration volume. At the same time, the copper powder mainly relies on gravity to settle rather than accumulate on the surface of the membrane layer. The membrane layer does not need to bear the weight of a large amount of copper powder, which fundamentally reduces the risk of clogging and damage to the membrane layer due to excessive load, effectively extends the service life of the membrane layer, reduces the frequency of downtime maintenance, and ensures the continuity and stability of production.

[0036] Working principle:

[0037] (1) Continuous copper powder production process: The copper powder scraped off from the cathode of the electrolytic cell 2 is deposited at the bottom of the electrolytic cell 2 under the action of gravity. The electrolyte flowing down from the high-level tank 1 has a certain kinetic energy, which can drive the copper powder at the bottom of the electrolytic cell 2 to move continuously towards the collection tank 3 (the second control valve 6 and the third control valve 12 are continuously open during the electrolytic production process). Then it enters the collection tank 3. Most of the copper powder is deposited at the bottom of the collection tank 3 under the action of gravity, while a small amount of copper powder moves towards the top of the collection tank 3 under the action of the electrolyte. After being filtered by the filter membrane layer 4, it is collected and finally deposited at the bottom of the collection tank 3 under the action of gravity. The electrolyte is then re-entered into the high-level tank 1 after passing through the filter membrane layer 4 under the action of the recovery pump 9. Then it continuously flows from the bottom of the high-level tank 1 into the electrolytic cell 2, thus completing one cycle.

[0038] (2) Copper powder collection process: When the copper powder in the collection tank 3 reaches the required set quantity, the production process of the electrolytic cell 2 is paused and the recovery pump 9 is turned off simultaneously. Then, the second control valve 8 and the third control valve 12 are turned off, and the fourth control valve 14 is turned on, so that the copper powder can be continuously transported to the collection end under the action of gravity. After the discharge is completed, the fourth control valve 14 is turned off, and then the second control valve 8 and the third control valve 12 are turned on. The first control valve 6 is turned on so that the electrolyte in the storage pipe enters the high-level tank 1 to replenish the electrolyte to the required amount. Then, the recovery pump 9 is turned on and the next round of electrolytic production process is carried out.
