Description

A solid-liquid separation device for silver electrolysis before material release

Technical Field

The utility model relates to the technical field of precious metal refining, in particular to a solid-liquid separation device used before silver electrolysis.

Background Art

Electrolytic silver is a production method that uses electrolytic reaction to reduce silver ions at the cathode to obtain metallic silver. Most of the electrolytic silver powder will adhere to the cathode plate. Generally, a manual or semi-automatic scraper is used to scrape the silver powder on the cathode surface. The scraped silver powder is deposited at the bottom of the electrolytic cell. By opening the valve at the bottom of the electrolytic cell, the silver powder and the electrolyte are discharged together, and then the silver powder is obtained through solid-liquid separation.

After searching, the Chinese patent with publication number CN211394657U discloses a solid-liquid separation device for silver electrolysis before discharging, which solves the problem of high time cost and labor intensity of using circulating tank filter cloth to filter electrolytic silver powder. The utility model includes a three-way filter, a filter screen is provided in the vertical channel of the three-way filter, the upper end interface of the three-way filter is the feed liquid inlet, and a valve I is provided at the feed liquid inlet, the right side of the three-way filter is the electrolyte discharge port, and a valve II is provided in the electrolyte discharge port, and the lower end outlet of the three-way filter is the electrolytic silver powder discharge port, and a valve III is provided at the electrolytic silver powder discharge port. By adopting the technical scheme of the utility model, the electrolytic silver powder and electrolyte of the silver electrolytic tank can be discharged separately, the electrolyte can be placed in the electrolyte circulation tank, and the electrolytic silver powder can be placed in the silver powder receiving vehicle and directly sent for cleaning, which reduces the time of electrolyte filtration; there is no need to collect silver powder on the manual filter cloth, which saves time and reduces labor intensity.

However, in the above technical solution, the electrolytic silver powder and electrolyte in the silver electrolytic cell are released and collected respectively by opening and closing multiple valves. The patent realizes the filtration of the electrolyte by setting a filter in the vertical channel of the three-way filter. The mesh of the filter is easy to be clogged over a long period of time, resulting in a decrease in the efficiency of screening and filtration. Therefore, the filter needs to be maintained and replaced frequently, and the flange connection is relatively complicated to disassemble and install. The three-way filter in the above patent adopts flange connection in many places, which increases the steps and parts that need to be disassembled when maintaining the filter.

The utility model can facilitate the disassembly and maintenance of the filter screen 5. When the filter screen 5 needs to be disassembled, it is only necessary to disassemble the flange at the connection between the discharge pipe 6 and the pipeline 4 to remove the discharge pipe 6 and the separation box 8. The fixed cylinder 9 can move in the guide groove 14 on the inner wall of the pipeline 4 through the guide block 15 on the outer peripheral surface. The fixed cylinder 9 slides in the limit groove 11 through the limit ball 12 and compresses the first spring 13. The first spring 13 contracts so that the fixed cylinder 9 can be moved for replacement. A scraper 20 that can reciprocate along the axis of the pipeline 4 is also provided in the cleaning mechanism. The scraper 20 is driven by the moving rod 21 connected to the valve core of the valve 3 to move and clean the silver powder in the valve body of the valve 3 to prevent the silver powder from adhering to the valve body and being crushed and ground by the valve core to cause waste.

Embodiment 2

As shown in Figures 1 to 4, the utility model proposes a solid-liquid separation device for silver electrolysis before discharging. Compared with the first embodiment, in this embodiment, the fixed assembly includes a fixed cylinder 9, a mounting ring 10, a limiting groove 11, a limiting ball 12 and a first spring 13. The two ends of the hollow circular fixed cylinder 9 are used to connect with the filter screen 5. The fixed cylinder 9 is placed on the mounting ring 10 connected to the inner wall of the pipeline 4. The fixed ring is provided with circumferentially distributed receiving grooves. The first spring 13 is connected to the receiving grooves. The first spring 13 is connected to the limiting ball 12 in the limiting groove 11. When the fixed cylinder 9 is installed, the fixed cylinder 9 enters the guide groove 14 on the discharge pipe 6 through the guide block 15 on the outer peripheral surface.

Embodiment 3

As shown in Figures 3 and 5, the utility model proposes a solid-liquid separation device for silver electrolytic release. Compared with the second embodiment, in this embodiment, the cleaning mechanism includes a baffle 16, a limit block 17, a limit rod 18, a second spring 19, a scraper 20 and a moving rod 21. The baffle 16 is connected to the inner wall of the pipeline 4. The baffle 16 is provided with circumferentially distributed through holes for passing the limit rod 18. One end of the limit rod 18 passes through the through hole to connect the scraper 20. The L-shaped moving rod 21 connected to the valve core of the valve 3 is slidably connected to the scraper 20. A second spring 19 sleeved on the outer peripheral surface of the limit rod 18 is connected between the baffle 16 and the scraper 20. The limit block 17 is connected to the other end of the limit rod 18. When the valve 3 is started, the handle on the valve body is rotated to drive the valve core to rotate. When the valve core rotates, the moving rod 21 on the valve core rotates and gradually contacts the scraper 20. The scraper 20 moves and stretches the length of the second spring 19 to drive the limit rod 18 and the limit block 17 to move. The scraper 20 blocks and scrapes the inner wall of the valve body to prevent the silver powder from adhering to the valve body and contacting the valve core.

One end of the scraper 20 is connected to a cleaning brush 22 for sliding connection with the pipe 4, and both the scraper 20 and the cleaning brush 22 are semicircular. When the scraper 20 moves, the cleaning brush 22 contacts and cleans the valve body of the valve 3 to prevent the silver powder attached to the valve body from getting stuck on the valve core. The semicircular scraper 20 and the cleaning brush 22 prevent contact with the valve core and cause the two to hinder each other.
