Description

Technical Field

[0001] This utility model belongs to the technical field of anode mud recycling and processing equipment, and specifically relates to an integrated device for leaching and pressure filtration of anode mud. Background Technology

[0002] In the wet processing and refining process of anode mud, there are often multiple leaching operations on the anode mud, and solid-liquid separation operations are required after leaching.

[0003] Filter bags possess both liquid permeability and solid particle blocking properties. Therefore, it's advisable to add a filter bag to the leaching container, add anode mud to the filter bag, and then add leaching solution for leaching. The leaching solution can freely permeate through the filter bag and overflow, thus achieving the filtration and separation of the leaching solution and anode mud solid residue. However, even with this natural filtration method, some leaching solution will still remain inside the filter bag, requiring further pressure filtration to ensure complete overflow and separation of the leaching solution.

[0004] However, if the pressure filtration operation is carried out directly in the leaching container, there will be many inconveniences. For example, considering that the same leaching solution often needs to be added to the anode mud multiple times during the leaching process to fully leach out a certain target component from the anode mud, the filter bag needs to be kept open. However, due to the presence of the opening, if the pressure filtration is carried out directly later, a large amount of anode mud solid residue will flow out of the filter bag through the opening and adhere to the inner wall of the leaching container, resulting in waste of raw materials and the need for subsequent cleaning. At the same time, pressure filtration will also cause the anode mud solid residue to be flattened and concentrated in a deeper part of the leaching container, making it difficult to remove the solid residue from the leaching container. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated leaching and pressure filtration device for anode mud, including a vertically oriented receiving cylinder, which is a rectangular structure with a rectangular opening at the top and a horizontally oriented cover plate that can be detachably installed on the top of the receiving cylinder.

[0006] A drive cylinder is fixedly installed in the cavity of the container. The drive cylinder extends vertically upward with a drive rod that is coaxial with the container. A perforated plate with a horizontal surface is fixedly connected to the top of the drive rod. The drive cylinder controls the drive perforated plate to slide back and forth coaxially in the cavity of the container through the drive rod.

[0007] A filter bag with an open top is fitted into the cavity of the receiving cylinder above the perforated plate. One of the opening edges of the filter bag extends outward to form a cover cloth for the filter bag. The filter bag and the cover cloth are integrated. Zippers are provided on the edges of the cover cloth away from the filter bag and the corresponding opening edges on the filter bag, so that the cover cloth covers the top opening of the filter bag.

[0008] As a preferred embodiment: a connecting cloth extends horizontally outward in a ring around the top opening of the filter bag on its vertical outer circumference. The connecting cloth is sewn inward to the filter bag. The connecting cloth has several holes that connect the upper and lower surfaces of the connecting cloth at intervals along its length.

[0009] The inner part of the top of the container cylinder is vertically recessed downwards, thus forming a stepped structure with a lower inner surface and a higher outer surface. On the lower horizontal step surface, a limiting post extends vertically upwards in correspondence with the sleeve hole. Each limiting post extends vertically upwards to be flush with the higher horizontal step surface. The limiting post is vertically inserted into the corresponding sleeve hole.

[0010] As a preferred embodiment: a horizontally oriented partition is fixedly installed in the cavity of the receiving cylinder, and the inner cavity of the receiving cylinder is divided into an upper cavity and a lower cavity by the partition. An installation chamber is fixedly connected to the lower plate of the partition, and the drive cylinder is fixedly installed in the installation chamber. The drive rod passes through the partition in a sealed fit along its own axis vertically upward and is fixedly connected to the lower plate of the orifice plate.

[0011] A discharge pipe extends vertically downwards from the mounting chamber along its radial direction on the partition, and the upper and lower cavities are connected by the discharge pipe.

[0012] As a preferred option, a solenoid valve is installed on the discharge pipe.

[0013] Preferably, the partition plate has a vertical through hole for the drive rod to pass through coaxially. The wall of the through hole is recessed horizontally outward to form a sealing groove coaxial with the through hole. The sealing ring coaxial with the through hole is fully embedded in the sealing groove. The drive rod passes through the sealing ring coaxially to achieve a sealed passage through the partition plate.

[0014] Preferably, each through hole on the perforated plate is vertically connected to the upper and lower surfaces of the perforated plate in the axial direction, and there is a through hole that is coaxially connected to the feed pipe.

[0015] As a preferred embodiment, each corner of the cover plate is provided with a vertical mounting hole that connects the upper and lower surfaces of the cover plate. The top of the receiving cylinder (on the horizontal high step of the step) is provided with a threaded hole that is coaxially connected to the mounting hole. The mounting bolts are tightened into the corresponding threaded holes by coaxially engaging vertically downwards through the mounting holes and then coaxially engaging with the bolts to achieve a secure fit between the cover plate and the receiving cylinder.

[0016] Preferably, the horizontal top of the receiving cylinder (on the horizontal high step surface and inside a ring of threaded holes) is recessed vertically downward to form a mounting groove coaxial with the receiving cylinder, and a sealing ring coaxial with the mounting groove is vertically and fully fitted into the mounting groove.

[0017] Preferably, a discharge pipe extends horizontally outward from a position on the container cylinder that is vertically downward and close to the bottom of the container cylinder, connecting the inner cavity of the container cylinder with the outside. Attached Figure Description

Detailed Implementation

[0025] It should be noted that the terms "horizontal" and "vertical" used in the description of this application refer to the attached... Figure 5 , 6In this context, "inner" and "outer" refer to directions toward or away from the geometric center of a specific component or structure, respectively. These are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] As shown in the attached diagram, the integrated leaching and filtration device for anode mud of this invention first includes a vertically oriented receiving cylinder 1. The receiving cylinder 1 is a vertically oriented cuboid structure. The top of the receiving cylinder 1 has a rectangular opening. A horizontally oriented cover plate 2 is detachably mounted on the top of the receiving cylinder 1. Vertically oriented mounting holes (not shown in the attached diagram) are provided at each corner of the cover plate 2, connecting the upper and lower surfaces of the cover plate 2. The circumferentially inward portion of the top of the receiving cylinder 1 is vertically recessed, forming an annular step at the top of the receiving cylinder 1, with the inner side lower than the outer side. The horizontal height of the step... The stepped surface has threaded holes 12 that are coaxially connected vertically to the mounting holes. Mounting bolts 8, which pass vertically downwards and coaxially through the mounting holes, are then screwed into the corresponding threaded holes 12, achieving a secure fit between the cover plate 2 and the receiving cylinder 1. Simultaneously, on the horizontal high-step surface of the step, inside a ring of threaded holes 12, a circumferentially vertically downward recess forms a mounting groove 14 coaxial with the receiving cylinder 1. A sealing ring 10 (rectangular sealing rubber ring) coaxial with the mounting groove 14 is vertically and fully embedded in the mounting groove 14 (as shown in the attached figure). Figure 1 This is to achieve a sealed cover between the cover plate 2 and the receiving cylinder 1;

[0027] As attached Figure 2 , 5 A horizontally oriented partition 6 is fixedly installed in the cavity of the receiving cylinder 1. The inner cavity of the receiving cylinder 1 is divided into an upper cavity and a lower cavity by the partition 6. An installation chamber 7 is fixedly connected to the lower surface of the partition 6. A drive cylinder 3 is fixedly installed in the installation chamber 7. A drive rod 31, coaxially arranged with the receiving cylinder 1, extends vertically upward from the drive cylinder 3. A through hole 62 is provided on the partition 6, which is axially vertical and allows the drive rod 31 to slide up and down coaxially. A sealing groove 63, coaxially arranged with the through hole 62, is formed by a horizontally recessed ring on the wall of the through hole 62. A sealing ring 64 (sealing rubber ring), coaxially arranged with the through hole 62, is fully embedded in the sealing groove 63. The drive rod 31 passes through the sealing ring 64 coaxially to achieve a sealed passage on the partition 6 (as shown in the attached figure). Figure 6 );

[0028] The top of the drive rod 31 is vertically upward and passes through the partition 6 and is fixedly connected to the perforated plate 4 with a horizontal plate surface. The drive cylinder 3 controls the drive perforated plate 4 to slide up and down in the inner cavity of the receiving cylinder 1 through the drive rod 31.

[0029] As attached Figure 3 A filter bag 5 with an open top is vertically and coaxially fitted above the perforated plate 4 in the upper cavity (i.e., the flexible filter bag 5, when fully expanded in its natural state, will form a vertical cuboid structure that matches the shape of the upper cavity), as shown in the attached figure. Figure 4 One edge of the top opening (rectangular opening) of the filter bag 5 extends outward to form a flap 51. The filter bag 5 and the flap 51 are integrally formed. The three edges of the flap 51 away from the filter bag 5 are detachably pulled together with the corresponding edges of the filter bag 5 by means of zippers 52, so that the flap 51 covers the top opening of the filter bag 5. At the same time, a ring extends horizontally outward from the top opening of the filter bag 5, which is coaxial with the filter bag 5. The connecting cloth 53 is stitched together with the filter bag 5 in the circumferential direction. The connecting cloth 53 has a number of uniformly spaced holes 531 that connect the upper and lower surfaces of the connecting cloth 53 along its own length. On the horizontal lower step surface of the top of the receiving cylinder 1, limit posts 11 extend vertically upward in correspondence with the holes 531. Each limit post 11 extends vertically upward along its own axis until it is flush with the horizontal higher step surface of the step, and the limit post 11 is vertically inserted into the corresponding hole 531.

[0030] In addition, as attached Figure 5 A discharge pipe 61 extends vertically downward from the partition plate 6 at a position away from the installation chamber 7 along its own radial direction. The upper cavity and the lower cavity are connected only through the discharge pipe 61. A solenoid valve 611 is installed on the discharge pipe 61. Several through holes 41 are distributed on the orifice plate 4, which are vertically connected to the upper and lower surfaces of the orifice plate 4 in the axial direction. One of the through holes 41 is coaxially connected to the discharge pipe 61. A discharge pipe 13 extends horizontally outward from a position close to the bottom of the cavity of the receiving cylinder 1, which connects the inner cavity of the receiving cylinder 1 with the outside.

[0031] Based on the above structural design, when leaching the anode mud is required, the cover plate 2 is opened and removed, and the filter bag 5 is fully opened and vertically placed downwards into the receiving cylinder 1. The connecting cloth 53 around the filter bag 5 has corresponding holes 531 that vertically fit downwards onto the limiting post 11 (as shown in the attached diagram). Figure 3 , 4Anode mud is added to filter bag 5 (the volume of the added anode mud in its natural state is about half that of the solvent in the upper cavity). By pre-setting the vertical length of filter bag 5, and combined with the sinking of the anode mud in filter bag 5, filter bag 5 is stretched and expanded vertically in the upper cavity. Filter bag 5 is then fitted into the upper cavity and rests against the perforated plate 4 (and is supported vertically by the perforated plate 4). Then, (with solenoid valve 611 closed), leaching solution is injected into it. The anode mud is soaked in the leachate. After soaking for a period of time, the solenoid valve 611 is opened, allowing the leachate to enter the lower chamber through the through hole 41 on the orifice plate 4 and the discharge pipe 61 on the partition plate 6. (Simultaneously, a delivery pipe equipped with a pump can be connected to the outer port of the discharge pipe 13. When the liquid is discharged through the discharge pipe 61, the leachate entering the lower chamber is immediately pumped to the storage tank of the leachate (not shown in the attached figure). This also allows the leachate from the upper chamber to fall into the lower chamber more smoothly and not accumulate in the lower chamber.) This completes one leaching operation. After closing the solenoid valve 611, the same leachate is added to the anode mud in the upper chamber for soaking again to perform a second leaching. This process is repeated until the target component is fully leachated.

[0032] During the intervals between each leaching operation, the anode mud can be manually stirred and turned over to an appropriate degree using a stirring rod to improve the subsequent leaching efficiency.

[0033] As attached Figure 3 The above-mentioned method involves vertically and downwardly fitting the sleeve holes 531 on the connecting cloth 53 around the filter bag 5 onto the limiting post 11, which ensures that the filter bag 5 remains stably open throughout the leaching process, facilitating operation. Furthermore, throughout the entire leaching operation, the perforated plate 4 inside the receiving cylinder 1 always rests parallel to the bottom of the partition plate 6, allowing the weight of the anode mud and leaching liquid in the filter bag 5 to fall fully onto the partition plate 6, thereby effectively reducing the pressure on the drive cylinder 3 itself during this stage and reducing the burden on the drive cylinder 3 and drive rod 31.

[0034] After the above leaching operation is completed, first pull the zipper 52 to close it, so that the flap cloth 51 covers the opening of the filter bag 5. Then, use the mounting bolts 8 to tighten and seal the cover plate 2 to the top of the receiving cylinder 1 to form a cover. Open the solenoid valve 611, and use the drive cylinder 3 and drive rod 31 to lift the perforated plate 4 vertically upward until the filter bag 5 containing anode mud above the perforated plate 4 is pressed vertically upward onto the lower plate surface of the cover plate 2 (as shown in the attached figure). Figure 5 The leachate squeezed out from the filter holes of the filter bag 5 falls through the through holes 41 on the perforated plate 4 and the gap between the horizontal periphery of the perforated plate 4 and the vertical inner wall of the receiving cylinder 1, and is also drawn away into the lower cavity, thus completing the pressure filtration operation of the anode mud.

[0035] During the aforementioned pressure filtration process, sealing the opening of the filter bag 5 prevents the anode mud inside the filter bag 5 from adhering to the inner wall of the receiving cylinder 1 and the lower plate surface of the cover plate 2. The sealing ring 10 at the top of the receiving cylinder 1 seals the cover plate 2 and the receiving cylinder 1, preventing the leachate from being forced out of the receiving cylinder 1 through the gap between the cover plate 2 and the top of the receiving cylinder 1 during the aforementioned pressure filtration operation, thus avoiding the loss and waste of leachate and the impact on the environment. After the pressure filtration operation is completed, since the filter bag 5 containing the anode mud is located at the opening of the receiving cylinder 1, it is convenient to remove the filter bag 5 from the receiving cylinder 1 after opening the cover plate 2, and then lower and reset the drive rod 31 and the orifice plate 4.
