Description

Technical Field

[0001] This utility model relates to the field of organosilicon monomer by-product treatment technology, and in particular to an improved copper-containing liquid filtration system. Background Technology

[0002] In current practices of by-product recycling in the organosilicon industry, particularly in the extraction of copper from organosilicon slurry, a technical bottleneck exists. The initial stage of the process involves using standard filters to remove large-volume impurities from the slurry soaking solution, followed by pumping the solution into a sedimentation tank. However, large particles clog the filters, affecting the efficiency of the slurry soaking tank's discharge. Small impurities enter the intermediate copper-containing tank with the copper-containing solution. These fine impurities, during subsequent chemical reactions with iron powder, penetrate and mix within the sponge copper structure, directly causing a decrease in the purity and quality of the final sponge copper product, severely impacting its market value and application performance. This problem highlights the urgent need to optimize and upgrade existing filtration systems to achieve finer filtration and improve by-product recovery efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an improved copper-containing liquid filtration system for filtering impurities in copper-containing liquids. This system not only improves the purity of sponge copper products but also solves the problem of prolonged liquid discharge time due to filter screen clogging.

[0004] To achieve this technical objective, the present invention adopts the following solution: An improved copper-containing liquid filtration system includes a slurry soaking tank, a sedimentation tank, a stirring tank, and an intermediate copper-containing liquid tank. The slurry soaking tank is connected to the sedimentation tank via a pipeline. A diaphragm pump is installed on the connecting pipeline between the slurry soaking tank and the sedimentation tank. A first trench is installed at the inlet of the sedimentation tank. The sedimentation tank and the stirring tank are connected via a second trench. A filter press is connected to the stirring tank via a pipeline. A filter press pump is installed on the connecting pipeline between the stirring tank and the filter press. The outlet of the filter press is connected to the intermediate copper-containing liquid tank. A filter screen is installed at the outlet of the slurry soaking tank, and a vibrator is installed above the filter screen.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention adds a vibrator to the filter screen of the slurry soaking tank, shortening the discharge time and improving the discharge efficiency. The copper-containing liquid first enters a sedimentation tank for settling, then flows by gravity along a first drainage ditch to a mixing tank. The mixing tank is equipped with a stirring device. A filter press pump transports the copper-containing liquid to a filter press. After small-volume impurities are removed by the filter press, the copper-containing liquid enters an intermediate copper-containing liquid tank for later use, thus improving the quality of the sponge copper product. The copper-containing liquid undergoes multiple filtration measures, including filter screen, drainage ditch sedimentation, sedimentation tank sedimentation, and filter press filtration, significantly improving filtration accuracy and efficiency. The resulting sponge copper product has a purity of over 75%, while simultaneously shortening the production cycle and improving overall production efficiency and economic benefits.

[0006] Furthermore, the slurry soaking tank includes a first slurry soaking tank and a second slurry soaking tank arranged in parallel. The outlets of the first slurry soaking tank and the second slurry soaking tank are respectively equipped with filter screens, and a vibrator is installed above the filter screens.

[0007] Furthermore, a stirring device is installed inside the mixing tank.

[0008] Furthermore, a filter is installed on the inlet pipeline of the filter press pump, and a pressure gauge and a drain valve are installed on the outlet pipeline.

[0009] Furthermore, the outlet pipeline of the filter press pump is connected to a pump loop pipeline, which is connected to the mixing tank.

[0010] Furthermore, the filter press is a plate and frame filter press.

[0011] Furthermore, the filter press has a ton container at the cake outlet.

[0012] Furthermore, both the outlet of the filter press pump and the inlet of the filter press are connected to reserved joints. Attached Figure Description

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] Please see Figure 1 This utility model provides an improved copper-containing liquid filtration system, including a slurry soaking tank, a sedimentation tank 3, a stirring tank 4, a filter press pump 5, a filter press 6, and a copper-containing liquid intermediate tank 7.

[0017] The outlet of the slurry soaking tank is equipped with a filter screen 12, and a vibrator 13 is installed above the filter screen 12. The slurry soaking tank is connected to the sedimentation tank 3 through a pipeline. A diaphragm pump 9 is installed on the pipeline connecting the slurry soaking tank and the sedimentation tank 3. A first trench 10 is installed at the inlet of the sedimentation tank 3. The sedimentation tank 3 and the mixing tank 4 are connected through a second trench 11.

A filter press pump 5 is installed on the pipeline connecting the mixing tank 4 and the filter press 6. The outlet of the filter press 6 is connected to the intermediate tank 7 containing copper liquid. A ton container 8 is installed at the mud cake outlet of the filter press 6.

[0018] In one specific embodiment, the slurry soaking tank includes a first slurry soaking tank 1 and a second slurry soaking tank 2 arranged in parallel. The outlets of the first slurry soaking tank 1 and the second slurry soaking tank 2 are respectively provided with filter screens 12, and a vibrator 13 is provided above the filter screens 12.

[0019] In one specific embodiment, a filter is installed on the inlet pipeline of the filter press 5, a pressure gauge and a drain valve are installed on the outlet pipeline, a pump loop pipeline 15 is installed at the outlet of the filter press 5, the pump loop pipeline 15 is connected to the mixing tank 4, and a valve is installed on the pump loop pipeline 15.

[0020] In one specific embodiment, two filter press pumps 5 are connected in parallel to facilitate system inspection and maintenance.

[0021] In one specific embodiment, the filter press 6 is a plate and frame filter press.

[0022] In one specific embodiment, both the outlet of the filter press pump 5 and the inlet of the filter press 6 are connected to reserved connectors 16 for pipeline purging or flushing to prevent pipeline blockage. The reserved connectors 16 can be connected to nitrogen for pipeline purging or to circulating water for pipeline flushing, depending on the specific circumstances.

[0023] The working process of this improved copper-containing liquid filtration system is as follows: After the organosilicon slurry residue is soaked in the first slurry residue soaking tank 1 and the second slurry residue soaking tank 2 for 20 hours, the outlet valve of the slurry residue soaking tank is opened, and the copper-containing liquid is screened through the filter screen 12 to remove large particles of impurities. A vibrator 13 is installed above the filter screen 12 to prevent the filter screen 12 from clogging and affecting the liquid discharge time. The copper-containing liquid with large particles removed is transported to the first drainage ditch 10 by the diaphragm pump 9, and then flows by gravity to the sedimentation tank 3 through the first drainage ditch 10. The settled copper-containing liquid then flows by gravity through the second drainage ditch 11 to the stirring tank 4. The stirring tank 4 is equipped with a stirring device 14 (stirring motor YBBP-160L-4P-dII). CT4), the copper-containing liquid in the mixing tank 4 is transported to the filter press 6 (model XMZFN100 / 1000-U) by the filter press pump 5 (model UHB-ZK65 / 30-50) for deep filtration. The filtrate is transported to the intermediate tank 7 containing copper liquid for standby. The sludge cake after filtration is directly poured into the ton tank 8 for collection. The outlet of the filter press pump 5 is equipped with a pump loop pipeline 15 and valve.
