Description

Technical Field

[0001] This utility model relates to the field of waste liquid recycling technology, and in particular to a device for recycling silver powder washing waste liquid. Background Technology

[0002] Silver powder washing is a process for cleaning silver powder, a type of metal powder widely used in industrial production, laboratory research, and some handicrafts. Due to factors such as the production process or storage environment, some impurities may adhere to the surface of the silver powder, such as additive residues, dust, oxides, etc. The purpose of washing is to remove these impurities to improve the purity and quality of the silver powder. The waste liquid from silver powder washing needs to be recycled and filtered to remove impurities and retain high-purity silver powder.

[0003] In existing methods for recycling silver powder washing waste liquid, most methods involve filtering the waste liquid through high-density filter cloth to separate the silver powder. However, since silver powder contains particulate impurities, including metal particles generated during metal friction during processing and impurities present in the cleaning liquid itself, once these impurities accumulate on the filter cloth, it not only reduces filtration efficiency but also easily causes blockage. Furthermore, this direct filtration method results in a large amount of impurities mixed in with the silver powder, thus reducing the purity of the silver powder.

[0004] Therefore, we propose a device for recovering silver powder washing waste liquid. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the recycling of silver powder washing waste liquid mostly involves filtering the waste liquid through high-density filter cloth to filter and sieve the silver powder. However, since silver powder contains particulate impurities, including metal particles generated by metal friction during processing and impurities present in the cleaning liquid itself, once these impurities accumulate on the filter cloth, it will not only reduce the filtration efficiency but also easily cause blockage. Furthermore, this direct filtration method will result in a large number of impurities mixed in with the silver powder, thereby reducing the purity of the silver powder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] The first rotating tube 4 is equipped with a multi-stage filtration device, and the multi-stage filtration device includes a second rotating tube 8. The outer surface of the second rotating tube 8 is mounted to the inner wall of the first rotating tube 4 through a bearing.

[0029] Example 2

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a second bevel gear 81 is fixedly sleeved on the outer surface of the second rotating pipe 8, and a conveying pipe 82 is installed on the inner wall of one end of the second rotating pipe 8 through a sealed bearing. A fixing block 83 is fixedly sleeved on the outer surface of the conveying pipe 82. The fixing block 83 serves to fix and support the conveying pipe 82. The conveying pipe 82 is connected to the external waste liquid discharge pipe through a flange at one end, and is easy to disassemble.

[0031] The lower end of the fixing block 83 is fixedly connected to the upper surface of the cover 3. The other end of the second rotating tube 8 passes through the first rotating tube 4 and extends into the interior of the recycling cylinder 1. The outer surface of the second rotating tube 8 is fixedly connected with symmetrically distributed second connecting rods 84. The cover 3 and the recycling cylinder 1 are detachably connected, which facilitates the cleaning of the recycling cylinder 1.

[0032] One end of each of the two second connecting rods 84 is fixedly connected to a primary filter cartridge 85. A drive rod 86 is fixedly connected to the outer surface of the second rotating tube 8. One end of the drive rod 86 is fixedly connected to an arc-shaped cleaning scraper 87. The outer ring and bottom of the primary filter cartridge 85 are detachably connected, which facilitates the treatment of internal impurities.

[0033] The outer surface of the arc-shaped cleaning scraper 87 contacts the inner wall of the secondary filter cylinder 7. A shovel 88 is fixedly connected to the inner surface of the arc-shaped cleaning scraper 87. The lower end of the shovel 88 contacts the inner bottom wall of the secondary filter cylinder 7. A servo motor 89 is fixedly installed on the upper surface of the cover 3 through a mounting base. The outer ring and bottom of the secondary filter cylinder 7 are detachably connected, which facilitates the treatment of internal impurities.

[0034] The output shaft of the servo motor 89 is fixedly mounted with a rotating shaft 810 via a coupling. A third bevel gear 811 is fixedly sleeved on the outer surface of one end of the rotating shaft 810. The tooth surfaces of the third bevel gear 811 mesh with the tooth surfaces of the first bevel gear 5 and the second bevel gear 81, respectively. An annular support block 812 is fixedly sleeved on the inner wall of the recovery cylinder 1. The rotation of the third bevel gear 811 drives the meshing first bevel gear 5 and the second bevel gear 81 to rotate in opposite directions.

[0035] An annular support block 812 has an annular filter frame 813 movably inserted into its inner wall. A filter cloth 814 is fixedly sleeved on the inner wall of the annular filter frame 813. A drain pipe 815 is fixedly connected to the lower surface of the recovery cylinder 1. A handle is provided on the annular support block 812 to facilitate the removal of the filter cloth 814.

[0036] The multi-stage filtration device separates large and small particles in the wastewater through rotation and centrifugation, greatly reducing the filtration burden on the subsequent filter cloth 814. The rotation cleaning process also prevents clogging during filtration, thus improving both the filtration efficiency of the silver powder waste liquid and the purity of the filtered silver powder.

[0037] The working process of this utility model:

[0038] Step 1: Connect one end of the washing waste liquid discharge pipe to the conveying pipe 82. The washing waste liquid is conveyed to the recovery cylinder 1 through the conveying pipe 82 and flows into the first-stage filter cylinder 85. At this time, the servo motor 89 is started. The servo motor 89 drives the third bevel gear 811 to rotate through the rotating shaft 810. The rotation of the third bevel gear 811 drives the first rotating pipe 4 and the second rotating pipe 8 to rotate in opposite directions through the meshing first bevel gear 5 and second bevel gear 81 respectively. The rotation of the second rotating pipe 8 drives the first-stage filter cylinder 85 to rotate through the second connecting rod 84. The centrifugal force when the first-stage filter cylinder 85 rotates intercepts larger impurities, and the remaining small particles of impurities, silver powder and wastewater flow into the second-stage filter cylinder 7.

[0039] Step two: The rotation of the first rotating tube 4 drives the rotation of the secondary filter cylinder 7 via the first connecting rod 6. The rotation of the secondary filter cylinder 7 intercepts small particulate impurities, allowing the silver powder and wastewater to flow out. Meanwhile, the rotation of the second rotating tube 8 drives the arc-shaped cleaning scraper 87 via the drive rod 86 to clean the impurities adsorbed on the inner wall of the secondary filter cylinder 7, preventing blockage. When the arc-shaped cleaning scraper 87 rotates and cleans, it drives the shovel 88 to scoop up the impurities and silver powder at the bottom, thus assisting in filtration and preventing the accumulation and sedimentation of silver powder, thereby improving the filtration quality.

[0040] Step 3: Finally, the wastewater and silver powder enter the filter cloth 814 for filtration. The wastewater enters the bottom of the recovery cylinder 1 through the filter cloth 814 and is discharged to the next processing step through the drain pipe 815. The silver powder is intercepted above the filter cloth 814. After filtration, the cover 3 can be lifted off the recovery cylinder 1 by external equipment, so that the filter cloth 814 can be taken out through the annular filter frame 813 to collect the silver powder.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
