Description

Technical Field

[0001] This utility model relates to the field of wet refining technology of anode mud, and more specifically, it relates to a low-carbon oriented leaching device for wet copper refining of anode mud. Background Technology

[0002] The low-carbon-oriented wet refining process for precious metals in anode slime is as follows: First, the copper anode slime is sulfated, roasted, and selenium-distilled to convert base metals such as copper into sulfates. Then, acid leaching removes copper, followed by ammonia leaching for silver separation, and finally chlorination for gold separation. After a certain period of time, the precipitate is separated, and the resulting copper sulfate solution is replaced with iron sheets to obtain crude copper. The replacement solution is pretreated and then discharged into the plant's wastewater treatment plant for centralized treatment. The precipitated copper slag is then sent to the gold separation process.

[0003] Patent CN214735989U discloses a copper anode mud treatment system, which includes an atmospheric pressure leaching copper removal kettle and a pressure leaching copper removal kettle arranged in sequence on four layers, a silver and selenium precipitation kettle and a tellurium precipitation kettle arranged on three layers, a tellurium precipitation post-liquid tank arranged on two layers, a slurry stirring tank arranged on one layer, and a solid-liquid separation kettle arranged on five layers. The copper anode mud diluted in the slurry stirring tank is pumped to the solid-liquid separation kettle. The supernatant outlet of the solid-liquid separation kettle is connected to the slurry stirring tank, and the precipitate outlet is connected to the atmospheric pressure leaching copper removal kettle in the lower layer.

[0004] Although the above-mentioned device can achieve the leaching of metals and solid-liquid separation in anode mud through various reaction vessels with different layers, the stirring, leaching and solid-liquid separation of anode mud need to be carried out in reaction vessels with different layers. The device has a complex structure and is inconvenient to directly separate the solution and precipitate after the reaction, so it is impossible to directly process the solution and precipitate separately. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-carbon guided leaching device for wet copper smelting of anode mud that realizes solid-liquid separation of solution and precipitate after the leaching reaction is completed, and facilitates direct subsequent processing of precipitate and solution.

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

[0007] A low-carbon guided leaching device for wet copper smelting using anode mud includes an outer cylinder, a cap disposed on the top of the outer cylinder, a filter cylinder disposed on the inner wall of the outer cylinder, and a sliding assembly disposed between the outer cylinder and the filter cylinder. The outer cylinder has an inlet pipe on its side wall and an outlet pipe at its bottom. The filter cylinder has a plurality of filter holes. The sliding assembly includes a sliding strip and a sliding rail that are slidably connected. The sliding strip is disposed around the outer wall of the filter cylinder, and the sliding rail is disposed around the inner wall of the outer cylinder.

[0008] The present invention is further configured such that: the slide bar and the slide rail are arranged in a vertical direction, and the slide rail includes a connecting part connected to the inner wall of the outer cylinder and a track adapted to the shape of the slide bar.

[0009] The present invention is further configured such that: the slider can slide along the track, and a limiting seat is provided at the bottom of the track.

[0010] By adopting the above technical solution, the lifting mechanism pulls the handle, at which time the slide bar on the outer wall of the filter cylinder slides along the slide rail on the inner wall of the outer cylinder until the slide bar and the slide rail separate, and the filter cylinder is taken out from the inside of the outer cylinder, which makes it easier to remove the anode mud from the filter cylinder later.

[0011] The present invention is further configured such that: an leaching chamber is provided inside the outer cylinder, and multiple support legs are arranged around the bottom of the outer cylinder.

[0012] The present invention is further configured such that: the inlet pipe is connected to the interior of the leaching chamber, and the outlet pipe is connected to the interior of the leaching chamber.

[0013] The present invention is further configured such that the filter holes are respectively opened on the cylinder wall and the bottom of the filter cylinder, and the top of the filter cylinder is symmetrically provided with handles.

[0014] The present invention is further configured such that: a stirring assembly is provided at the center of the top of the cover, and a feed pipe is provided on one side of the stirring assembly, the feed pipe extending downward through the cover.

[0015] The present invention is further configured such that: the stirring assembly includes a stirring shaft that penetrates the cover, a motor disposed at the end of the stirring shaft, and a plurality of stirring blades disposed along the stirring shaft.

[0016] The beneficial effects of this utility model are:

[0017] The anode mud inside the filter cylinder comes into contact with the leachate inside the outer cylinder through the filter holes, undergoing a leaching reaction. After the leaching reaction is complete, the filter cylinder is removed from the outer cylinder by sliding the slider along the slide rail, thus separating the anode mud from the leaching device. Simultaneously, the solution that has undergone reaction in the leaching chamber is discharged through the outlet pipe. This process ensures that the leaching reaction is fully completed while achieving solid-liquid separation, facilitating subsequent separate treatment of the solution and anode mud.

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figure 1-3A low-carbon oriented leaching device for wet copper smelting using anode mud includes an outer cylinder 2, a cap 1 positioned at the top of the outer cylinder 2, a filter cylinder 3 positioned inside the outer cylinder 2, a sliding assembly 5 positioned between the outer cylinder 2 and the filter cylinder 3, and a stirring assembly 4 positioned on the cap 1. During leaching, the cap 1 is sealed at the top of the outer cylinder 2, anode mud is injected into the filter cylinder 3, and leaching solution is injected into the outer cylinder 2. The leaching solution comes into contact with the anode mud, causing a leaching reaction. The stirring assembly 4 stirs the anode mud to accelerate the reaction. After the reaction is complete, the solution is discharged, the cap 1 is opened, and the filter cylinder 3 is removed using a lifting mechanism, achieving solid-liquid separation of the anode mud and solution, facilitating subsequent direct processing of the anode mud and solution.

[0033] Please refer to Figure 1-3 The bottom of the cover 1 is connected to the top of the outer cylinder 2. The cover 1 and the outer cylinder 2 are connected by multiple connecting bolts 13, thereby achieving a seal on the outer cylinder 2. The cover 1 can be separated from the outer cylinder 2 by removing the connecting bolts 13. The cover 1 is provided with a feed pipe 11, which extends downward through the cover 1. The feed pipe 11 communicates with the inside of the outer cylinder 2. The end of the feed pipe 11 is provided with a feed port 12. Anode mud can be injected into the feed pipe 11 through the feed port 12 and finally enter the filter cylinder 3 through the feed pipe 11.

[0034] Please refer to Figure 1-6 The outer cylinder 2 is a cylindrical structure with an open top. Multiple support legs 26 are arranged around the bottom of the outer cylinder 2, and the support legs 26 are fixedly connected to the side wall of the outer cylinder 2. A leaching chamber 23 is provided inside the outer cylinder 2, and the filter cylinder 3 is located inside the leaching chamber 23. An inlet pipe 21 is provided on the side wall of the outer cylinder 2, and the height of the inlet pipe 21 is lower than the top height of the filter cylinder 3. The inlet pipe 21 communicates with the interior of the leaching chamber 23, and an inlet port 22 is provided at the end of the inlet pipe 21. The leaching solution can enter the inlet pipe 21 through the inlet port 22 and is finally discharged into the leaching chamber 23 through the inlet pipe 21. An outlet pipe 24 is provided at the bottom of the outer cylinder 2, located at the center of the outer cylinder 2. The outlet pipe 24 communicates with the interior of the leaching chamber 23, and an outlet port 25 is provided at the end of the outlet pipe 24. The solution that has completed the reaction in the leaching chamber 23 can be discharged through the outlet pipe 24 and finally discharged from the outlet port 25. It should be noted that a valve (not shown in the figure) is installed at the outlet pipe 24, which can be used to open or close the outlet 25. During the leaching reaction, the outlet 25 remains closed, and when the solution is discharged after the reaction is completed, the outlet 25 remains open.

[0035] Please refer to Figure 3-5 and Figure 7The filter cylinder 3 is a cylindrical structure with an open top, and its outer diameter is smaller than that of the outer cylinder 2. Several filter holes 34 are provided on the filter cylinder 3, located on the cylinder wall 32 and bottom 33. After the anode mud enters the filter cylinder 3, it can come into contact with the leachate through the filter holes 34 on the cylinder wall 32 and bottom 33 to undergo a leaching reaction. Simultaneously, the filter holes 34 isolate the anode mud inside the filter cylinder 3, facilitating subsequent solid-liquid separation. Two handles 31 are symmetrically arranged on the top of the filter cylinder 3, each connected to the inner wall of the cylinder wall 32. Both handles 31 are positioned from the inner wall of the cylinder wall 32 towards the axis of the filter cylinder 3. By pulling the handles 31 using a lifting mechanism, the filter cylinder 3 can be removed from the outer cylinder 2.

[0036] Please refer to Figure 1-3 A stirring assembly 4 is located at the center of the top of the cover 1, and a feed pipe 11 is located on one side of the stirring assembly 4. The stirring assembly 4 includes a stirring shaft 42 that passes through the cover 1, a motor 41 located at the end of the stirring shaft 42, and multiple stirring blades 43 arranged along the stirring shaft 42. The stirring shaft 42 is coaxially arranged with the filter cylinder 3, the motor 41 is mounted on the cover 1, and multiple stirring blades 43 are arranged around the stirring shaft 42. The motor 41 can drive the stirring shaft 42 to rotate. During the rotation of the stirring shaft 42, the stirring blades 43 stir the anode mud in the filter cylinder 3, thereby increasing the contact between the anode mud and the leachate. The stirring blades 43 are arranged at different heights along the stirring shaft 42, which can stir the anode mud at different heights in the filter cylinder 3, ensuring that the anode mud at different heights can fully contact the leachate.

[0037] Please refer to Figure 5-7 The sliding assembly 5 includes a sliding strip 51 and a sliding rail 52 that are slidably connected. The sliding strip 51 is arranged around the outer wall of the filter cylinder 3, and the sliding rail 52 is arranged around the inner wall of the outer cylinder 2. The sliding connection between the outer cylinder 2 and the filter cylinder 3 is achieved through the sliding strip 51 and the sliding rail 52. The sliding strip 51 and the sliding rail 52 are arranged vertically, and the position of the sliding strip 51 on the filter cylinder 3 corresponds to the position of the sliding rail 52 on the outer cylinder 2. The sliding rail 52 includes a connecting part 521 that connects to the inner wall of the outer cylinder 2 and a track 522 that is adapted to the shape of the sliding strip 51. The connecting part 521 is fixedly connected to the inner wall of the outer cylinder 2, and the connecting part 521 and the track 522 are integrally formed. The sliding strip 51 can slide along the track 522, and a limiting seat 523 is provided at the bottom of the track 522. The width of the limiting seat 523 is greater than the width of the track 522. When the bottom of the sliding strip 51 contacts the limiting seat 523, the limiting seat 523 can limit the sliding strip 51, thereby fixing the position of the filter cylinder 3.

[0038] Specifically, before the leaching reaction, the cap 1 is fixed to the top of the outer cylinder 2 by the connecting bolt 13 to achieve a seal on the outer cylinder 2. Then, the anode mud is injected into the feed pipe 11 through the feed port 12, and finally enters the filter cylinder 3 through the feed pipe 11; the leachate is introduced into the feed pipe 21 through the liquid inlet 22, and finally discharged into the leaching chamber 23 through the liquid inlet 21.

[0039] After the leachate enters the leaching chamber 23, it comes into contact with the anode mud through the filter holes 34 on the cylinder wall 32 and the bottom 33 to carry out the leaching reaction. At the same time, the filter holes 34 can isolate the anode mud inside the filter cylinder 3, which facilitates subsequent solid-liquid separation. During the leaching reaction, the motor 41 drives the stirring shaft 42 to rotate. During the rotation of the stirring shaft 42, the stirring blades 43 stir the anode mud in the filter cylinder 3, thereby increasing the contact between the anode mud and the leachate and ensuring that the leaching reaction is fully carried out.

[0040] After the leaching reaction is complete, the outlet 25 is opened, and the solution that has completed the reaction in the leaching chamber 23 is discharged through the outlet pipe 24 and finally discharged from the outlet 25. At the same time, the detachable connecting bolt 13 separates the cap 1 from the outer cylinder 2. After the cap 1 is removed, the handle 31 is pulled by the lifting mechanism. At this time, the slide bar 51 on the outer wall of the filter cylinder 3 slides along the slide rail 52 on the inner wall of the outer cylinder 2 until the slide bar 51 and the slide rail 52 separate, and the filter cylinder 3 is taken out from the inside of the outer cylinder 2, which facilitates the subsequent removal of the anode mud from the filter cylinder 3. After the anode mud is removed, the filter cylinder 3 is placed inside the outer cylinder 2 by the lifting mechanism, and the slide bar 51 is limited by the limiting seat 523 to fix the filter cylinder 3 inside the outer cylinder 2.

[0041] The anode mud inside the filter cylinder 3 comes into contact with the leachate inside the outer cylinder 2 through the filter holes 34, and a leaching reaction takes place. After the leaching reaction is completed, on the one hand, the slide bar 51 slides along the slide rail 52, causing the slide bar 51 and the slide rail 52 to separate, and the filter cylinder 3 is removed from the inside of the outer cylinder 2, thereby separating the anode mud from the leaching device; on the other hand, the solution that has completed the reaction in the leaching chamber 23 is discharged through the liquid outlet pipe 24. This achieves solid-liquid separation while ensuring that the leaching reaction is fully completed, which facilitates the subsequent separate treatment of the solution and the anode mud.
