Description

Technical Field

[0001] This invention relates to the field of copper smelting wastewater treatment technology, and more specifically, to an integrated device for deep treatment and reuse of copper smelting wastewater. Background Technology

[0002] Copper smelting generates a large amount of copper-containing wastewater, which contains copper ions, suspended particulate matter, heavy metal oxides, and other impurities. If discharged directly without proper treatment, it will not only waste water resources but also pose a serious threat to the ecological environment. Currently, the main methods for treating copper smelting wastewater include chemical precipitation, membrane filtration, hydrocyclone separation, and mechanical pressure filtration. However, traditional filtration and separation equipment usually requires external electric power to drive pumps, motors, and other power components, resulting in high energy consumption and operating costs. In particular, the applicability of such equipment is severely limited in remote mining areas or locations with unstable power supply.

[0003] Furthermore, copper-containing wastewater has a high concentration of suspended particulate matter, making filter elements prone to clogging during long-term use. This leads to a sharp decline in filtration efficiency, requiring frequent shutdowns for manual cleaning or filter media replacement, severely impacting the equipment's continuous operation and processing efficiency. Simultaneously, existing solid-liquid separation and dewatering equipment are typically independent multi-stage treatment units, occupying large areas, with complex piping connections and cumbersome processes. Even after primary filtration, the copper-containing slurry still has a high water content, requiring separate filter presses or centrifugal dewatering machines for further dewatering. This not only increases equipment investment but also involves multiple intermediate transfer steps, easily causing secondary pollution and copper resource loss.

[0004] Therefore, there is an urgent need to develop a deep treatment device for copper smelting wastewater that is energy-efficient, clog-resistant, compact in structure, and integrates filtration, separation, and dehydration, in order to solve the aforementioned problems in the existing technology. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, this invention proposes an integrated equipment for the deep treatment and reuse of copper smelting wastewater.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] Integrated equipment for deep treatment and reuse of copper smelting wastewater includes:

[0008] The main structure includes an upper support cylinder and a guide cone that is tapered at the top and at the bottom. The top of the guide cone is provided with a first connecting flange, and the bottom of the outer side of the upper support cylinder is provided with a first support ring.

[0009] A spiral water inlet pipe is connected tangentially to the side wall of the upper support cylinder;

[0010] The filtration mechanism includes an impeller assembly, a first drive shaft, a second support ring, and an elastic filter cone. The impeller assembly is driven by a spiral water flow and drives the first drive shaft to rotate. The elastic filter cone is sleeved on the outside of the second support ring and rotates with the second support ring to achieve centrifugal separation.

[0011] The support mechanism includes a connecting ring, a mounting base, and a support roller. The connecting ring is fixed to the upper end of the elastic filter cone, and the bottom of the connecting ring rests on the top surface of the first connecting flange and can rotate relative to it. The support roller is mounted on the upper end surface of the connecting ring via the mounting base and is supported on the top surface of the first support ring for rolling.

[0012] The spiral extrusion mechanism includes an extrusion cylinder and a spiral extrusion plate. The driving bevel gear at the lower end of the first drive shaft meshes with the driven bevel gear on the spiral extrusion plate. The spiral spacing of the spiral extrusion plate gradually decreases along the discharge direction.

[0013] As a further optimization of the present invention, the main body structure further includes a lower support cylinder and a drainage cylinder, the lower end of the guide cone is connected to the upper end of the lower support cylinder, the drainage cylinder is connected to the side wall of the lower support cylinder in a horizontal direction, and the spiral extrusion mechanism is disposed inside the drainage cylinder.

[0014] As a further optimization of the present invention, the upper support cylinder has multiple water outlet holes on its side wall, the inner wall of the upper support cylinder is provided with a limiting ring groove, the support mechanism also includes a limiting ring, the limiting ring is disposed on the connecting ring and embedded in the limiting ring groove to limit axial displacement, and a flow guide baffle is fixedly provided inside the lower support cylinder.

[0015] As a further optimization of the present invention, the top surface of the first connecting flange forms an annular support surface for the bottom of the connecting ring to rest and slide. The connecting ring and the first connecting flange are in surface contact rotational fit. The upper support cylinder is placed on the support roller through the first support ring, and thus the support cylinder is detachably mounted on the first connecting ring.

[0016] As a further optimization of the present invention, the filtration mechanism further includes a spiral guide vane, which is disposed at the upper opening of the elastic filter cone and connected to the first drive shaft, for guiding the spiral water flow downward into the interior of the elastic filter cone.

[0017] As a further optimization of the present invention, an inner guide baffle is provided on the inner wall of the elastic filter cone. The inner guide baffle is inclined along the inner wall of the elastic filter cone to guide the wastewater to flow towards the cone wall to enhance the centrifugal filtration effect.

[0018] As a further optimization of the present invention, an arc-shaped protrusion is provided on the outer edge of the second support ring, and a plurality of cleaning components are provided circumferentially on the inner wall of the flow guide cone. The cleaning components are located in the annular gap space between the flow guide cone and the elastic filter cone. When the arc-shaped protrusion rotates with the second support ring, it intermittently presses the cleaning components, driving the cleaning components to intermittently knock on the outer wall of the elastic filter cone.

[0019] As a further optimization of the present invention, the cleaning assembly includes a support base, a cam, an active connecting rod, a second drive shaft, a passive connecting rod, a spring, and a striking block. The support base is fixedly installed on the inner wall of the flow guide cone. The second drive shaft is rotatably inserted into the support base. The active connecting rod is fixedly connected to the bottom of the second drive shaft. The cam is installed on one side of the active connecting rod with its protruding end facing the rotation path of the arc-shaped protrusion. The passive connecting rod is fixed to the upper part of the second drive shaft. The striking block is fixedly connected to the end of the passive connecting rod and faces the outer wall of the elastic filter cone. One end of the spring is connected to the passive connecting rod, and the other end is connected to the inner wall of the flow guide cone. When the arc-shaped protrusion presses against the cam, it causes the active connecting rod, the second drive shaft, and the passive connecting rod to deflect, causing the striking block to strike the outer wall of the elastic filter cone and stretch the spring.

[0020] As a further optimization of the present invention, the filtration mechanism further includes a discharge pipe, which is sleeved at the bottom small opening of the elastic filter cone, and the outlet end of the discharge pipe is connected to the feed end of the screw extrusion mechanism.

[0021] As a further optimization of the present invention, the impeller assembly includes a disk and a plurality of blades evenly arranged along the circumference of the disk. The blades are inclined to withstand the impact force of the spiral water flow and drive the disk to rotate. The center of the disk is fixedly connected to the upper end of the first transmission shaft.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. This invention introduces wastewater into the upper support cylinder in a spiral reflux state through a spiral inlet pipe, which drives the impeller assembly to rotate. The transmission shaft synchronously drives the support ring and the elastic filter cone to rotate at high speed to achieve centrifugal separation. The active bevel gear and the driven bevel gear mesh to drive the spiral extrusion blade to perform progressive extrusion dewatering of copper-containing sludge by gradually reducing the spiral spacing. The entire process is driven by the kinetic energy of the wastewater itself, without the need for an additional motor or other external power source, which greatly reduces the energy consumption and operating cost of the equipment.

[0024] 2. This invention utilizes the intermittent pressure of the arc-shaped protrusion on the outer edge of the support ring against the cam mounted on one side of the active connecting rod during rotation. This causes the active connecting rod to drive the transmission shaft to deflect, which in turn drives the passive connecting rod and the striking block fixedly connected to its end to offset towards the outer wall of the elastic filter cone, striking and stretching the spring. When the arc-shaped protrusion disengages from the cam, the spring's rebound force drives all components to reset. This achieves periodic and intermittent striking of the outer wall of the elastic filter cone, causing it to vibrate elastically and automatically shake off the attached copper-containing particles and filter cake, effectively preventing filter blockage.

[0025] 3. In this invention, the bottom of the connecting ring is mounted on the top surface of the first connecting flange to form a rotatable support. The support roller is mounted on the upper end face of the connecting ring via the mounting seat and rolls on the top surface of the support ring at the bottom outside the upper support cylinder. The upper support cylinder is placed on the support roller through the support ring, so that a detachable structure is formed between the upper support cylinder and the guide cone. This ensures the smooth rotation of the filtration mechanism and facilitates equipment disassembly, maintenance, and internal inspection and cleaning. Attached Figure Description

[0042] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0043] Example 1

[0044] like Figures 1 to 9 As shown, the integrated equipment for deep treatment and reuse of copper smelting wastewater includes a main body 100, a spiral inlet pipe 200, a support structure 300, a spiral extrusion mechanism 400, and a filtration mechanism 500.

[0045] The main structure 100 includes an upper support cylinder 104, a guide cone cylinder 102, a lower support cylinder 101, a first connecting flange 103, and a drain cylinder 105. The upper support cylinder 104 is a cylindrical structure with an end cap at its upper end and a through hole in the center of the end cap for the first drive shaft 507 to pass through. A set of water outlet holes 107 are provided on the side wall of the upper support cylinder 104. The water outlet holes 107 are the inlet ports of the spiral water inlet pipe 200. The end of the spiral water inlet pipe 200 is connected to the water outlet holes 107. Copper smelting wastewater is introduced into the upper support cylinder 104 tangentially through the spiral water inlet pipe 200 and the water outlet holes 107. The inner wall of the upper support cylinder 104 is provided with a limiting ring groove 108. The bottom outer side of the upper support cylinder 104 is provided with a first support ring 109. The first support ring 109 extends outward in the form of an annular horizontal flange structure, and its top surface is a smooth plane for the support roller 303 to roll on it.

[0046] The guide cone 102 has a conical structure that is larger at the top and smaller at the bottom; the first connecting flange 103 is fixedly installed at the top of the guide cone 102, and has a horizontal annular flange structure, with its top surface forming a smooth annular support surface; the lower end of the guide cone 102 is fixedly connected to the upper end of the lower support cylinder 101; the lower support cylinder 101 is a cylindrical body, and its bottom end is provided with a mounting flange for fixing the entire equipment on the support foundation; the drain cylinder 105 is connected to the side wall of the lower support cylinder 101 in the horizontal direction, and is used to accommodate the screw extrusion mechanism 400 and discharge the separated wastewater; a guide baffle 106 is fixedly installed inside the lower support cylinder 101, which supports the lower end of the first drive shaft 507 on one hand, and is used to receive the centrifugally separated wastewater falling along the inner wall of the guide cone 102 and guide it into the drain cylinder 105.

[0047] It should be noted that the upper support cylinder 104 and the guide cone 102 are not tightly connected; the first connecting flange 103 is fixed to the top of the guide cone 102, and the bottom of the connecting ring 301 rests on the top surface of the first connecting flange 103. The two are in a surface contact rotational fit, allowing the connecting ring 301 to rotate freely relative to the first connecting flange 103. The first connecting flange 103 provides vertical support to the connecting ring 301 and the entire filter mechanism 500 it supports from below. The mounting base 304 is fixed to the upper end face of the connecting ring 301, and the support roller 303 is mounted on the mounting base 304. The rolling surface of the support roller 303 rests on the top surface of the first support ring 109 at the bottom outer side of the upper support cylinder 104. Therefore, the upper... The support cylinder 104 rests on the support roller 303 via the first support ring 109 at its outer bottom. The support roller 303 is located on the upper end face of the connecting ring 301, which in turn rests on the first connecting flange 103. When the filter mechanism 500 rotates under the drive of water flow, the connecting ring 301 rotates relative to the first connecting flange 103, and the support roller 303 rolls along the top surface of the first support ring 109, providing stable support for the upper support cylinder 104 while reducing rotational friction resistance. Lifting the upper support cylinder 104 upwards allows the first support ring 109 to detach from the support roller 303, enabling the upper support cylinder 104 to be detachably separated from the guide cone 102, facilitating equipment maintenance and repair as well as the replacement and cleaning of the internal filter structure.

[0048] The spiral inlet pipe 200 is connected tangentially to the outlet hole 107 on the side wall of the upper support cylinder 104; the copper smelting wastewater is driven by an external pump or by gravitational potential energy, and is introduced into the upper support cylinder 104 tangentially through the outlet hole 107 via the spiral inlet pipe 200, forming a high-speed rotating spiral water flow under the constraint of the inner wall of the cylinder.

[0049] The filtration mechanism 500 is rotatably disposed inside the main body 100 and includes an impeller assembly 501, an elastic filter cone 502, a cleaning component 503, a discharge pipe 504, a second support ring 505, a spiral guide vane 506, a first drive shaft 507, a drive bevel gear 508, an arc-shaped protrusion 509, and an inner guide baffle 510.

[0050] The impeller assembly 501 is located in the upper space of the upper support cylinder 104 and includes a disc and multiple blades uniformly fixed along the circumference of the disc. The blades are set at an inclined angle. When the high-speed spiral water flow impacts the blades, the impeller assembly 501 is driven to rotate under the action of water force, thereby converting the kinetic energy of the water flow into mechanical rotational energy.

[0051] The first drive shaft 507 is arranged vertically, with its upper end fixedly connected to the center of the disc of the impeller assembly 501, and its lower end extending into the lower support cylinder 101. The first drive shaft 507 is supported and positioned at its lower end by the bearing seat on the guide baffle 106; the active bevel gear 508 is fixedly installed at the lower end of the first drive shaft 507.

[0052] Three second support rings 505 are fixedly disposed on the first drive shaft 507 at axial intervals, respectively located at the upper, middle and lower parts of the first drive shaft 507; the diameter of the three second support rings 505 decreases from top to bottom, matching the conical inner cavity profile of the guide cone 102; each second support ring 505 is fixedly connected to the first drive shaft 507 through spokes, forming a radial rigid support structure; an arc-shaped protrusion 509 is provided on the outer edge of the second support ring 505, and the arc-shaped protrusion 509 rotates synchronously with the second support ring 505.

[0053] The elastic filter cone 502 has a cone-shaped structure that is wider at the top and narrower at the bottom. It is made of elastic metal wire mesh, and micropores are evenly distributed on the cylinder wall to allow water to pass through while trapping copper-containing suspended particles. The elastic filter cone 502 is sleeved on the outside of the three second support rings 505, supported by the second support rings 505 and rotating synchronously with the first drive shaft 507. The elastic filter cone 502 is set inside the guide cone 102, and an annular gap space is formed between the two. Multiple inner guide baffles 510 are provided on the inner wall of the elastic filter cone 502. The inner guide baffles 510 are inclined along the cylinder wall to guide the wastewater to flow towards the cylinder wall during rotation, thereby enhancing the centrifugal force to separate solid particles.

[0054] The spiral guide vane 506 is disposed at the upper opening of the elastic filter cone 502 and connected to the first drive shaft 507, for effectively guiding the spiral water flow from the impeller assembly 501 area downward into the interior of the elastic filter cone 502.

[0055] The discharge pipe 504 is fitted at the small opening at the bottom of the elastic filter cone 502, and the discharge pipe 504 is directly connected to the inside of the extrusion cylinder 401. The copper-containing slurry concentrated after centrifugal separation slides downward along the cone surface of the elastic filter cone 502 under the action of gravity and water flow, and is discharged directly into the inside of the extrusion cylinder 401 through the discharge pipe 504, where it is dewatered by the spiral extrusion plate 402.

[0056] The cleaning assembly 503 is disposed on the inner wall of the guide cone 102, located in the annular gap space between the guide cone 102 and the elastic filter cone 502, and multiple sets are arranged at intervals along the circumference; such as Figure 9As shown, each cleaning assembly 503 includes a support base 5032, a cam 5033, an active connecting rod 5034, a second drive shaft 5031, a passive connecting rod 5035, a spring 5036, and a striking block 5037. The support base 5032 is fixedly installed on the inner wall of the guide cone 102. The second drive shaft 5031 is rotatably inserted into the shaft hole of the support base 5032. The active connecting rod 5034 is fixedly connected to the bottom of the second drive shaft 5031 and extends to one side. The cam 5033 is installed on one side of the active connecting rod 5034, with its protruding end facing the arc. The rotation path of the protrusion 509 extends so that the arc-shaped protrusion 509 can contact and squeeze the cam 5033 during rotation; the passive connecting rod 5035 is fixed to the upper part of the second drive shaft 5031 and is arranged at a certain angle with the active connecting rod 5034; the striking block 5037 is fixedly connected to the end of the passive connecting rod 5035, and its striking surface faces the outer wall of the elastic filter cone 502; one end of the spring 5036 is connected to the passive connecting rod 5035, and the other end is connected to the inner wall of the guide cone 102, which is used to provide a restoring elastic force after the striking action is completed.

[0057] The working principle of the cleaning component 503 is as follows: When the first drive shaft 507 drives the second support ring 505 to rotate, the arc-shaped protrusion 509 on the outer edge of the second support ring 505 rotates in the annular gap space between the elastic filter cone 502 and the guide cone 102. The arc-shaped protrusion 509 intermittently contacts and squeezes the cam 5033 on the rotation path. After being squeezed, the cam 5033 shifts, causing the active connecting rod 5034 connected to it to deflect. The deflection of the active connecting rod 5034 drives the second drive shaft 5031 to rotate around the shaft hole of the support seat 5032 by a certain angle. The rotation of the second drive shaft 5031 synchronously drives the passive connecting rod 5035 above it to shift towards the outer wall of the elastic filter cone 502. The striking block 5037 fixedly connected to the end of the passive connecting rod 5035 then moves closer to the outer wall of the elastic filter cone 502 and strikes it. During this striking process, the spring 5036 is stretched and stores energy. When the arc-shaped protrusion 509 continues to rotate and disengages from the cam 5033, the cam 5033 loses external pressure, and the spring 5036 releases the stored elastic potential energy to generate a rebound force, driving the passive connecting rod 5035, the second transmission shaft 5031, the active connecting rod 5034, and the cam 5033 to return to their initial positions as a whole. The striking block 5037 then moves away from the outer wall of the elastic filter cone 502. As the second support ring 505 continues to rotate, the arc-shaped protrusion 509 periodically presses the cam 5033, causing the striking block 5037 to intermittently and rhythmically strike the outer wall of the elastic filter cone 502. After being struck, the elastic filter cone 502 generates elastic vibration, causing the copper-containing particles and filter cake attached to the inner and outer surfaces of the cone wall to fall off under the action of vibration, thereby achieving the function of automatic cleaning and preventing clogging.

[0058] The support mechanism 300 is disposed in the connection area between the upper support cylinder 104 and the guide cone 102, such as Figure 8 As shown, the system includes a connecting ring 301, a limiting ring 302, a support roller 303, and a mounting base 304. The connecting ring 301 has an annular structure, and its inner edge is fixedly connected to the upper opening edge of the elastic filter cone 502. The bottom of the connecting ring 301 rests on the top surface of the first connecting flange 103. The top surface of the first connecting flange 103 is a smooth annular plane, and the bottom surface of the connecting ring 301 and the top surface of the first connecting flange 103 are in surface contact rotational fit, allowing the connecting ring 301 to rotate freely on the top surface of the first connecting flange 103. The limiting ring 302 is located on the outer edge of the connecting ring 301, and has an annular protrusion structure. It is embedded in the limiting ring groove 108 on the inner wall of the upper support cylinder 104, restricting the axial movement of the filter mechanism 500 as a whole. The mounting base 304 is fixedly located on the upper end face of the connecting ring 301, and multiple bases are evenly spaced along the circumference. Roller 303 is rotatably mounted on mounting base 304, and the rolling surface of supporting roller 303 is supported on the top surface of first support ring 109 at the bottom outer side of upper support cylinder 104. When the filter mechanism 500 rotates under the drive of water flow, connecting ring 301 rotates relative to first connecting flange 103, and supporting roller 303 rolls along the top surface of first support ring 109, providing a stable support base for upper support cylinder 104 and reducing rotational friction resistance. Upper support cylinder 104 is placed on top of supporting roller 303 via first support ring 109, supporting roller 303 is mounted on connecting ring 301 via mounting base 304, and connecting ring 301 is placed on first connecting flange 103. The three are detachably connected. Lifting upper support cylinder 104 upwards will allow first support ring 109 to detach from supporting roller 303, achieving overall disassembly.

[0059] The screw extrusion mechanism 400 is located inside the drain cylinder 105, such as... Figure 3 and Figure 6As shown, the system includes an extrusion cylinder 401, a spiral extrusion plate 402, and a driven bevel gear 403. The extrusion cylinder 401 is a cylindrical body, located inside the drainage cylinder 105, and its length is greater than that of the drainage cylinder 105. The end of the extrusion cylinder 401 extends beyond the end of the drainage cylinder 105. The cylinder wall of the extrusion cylinder 401 has a filtering function, with micropores or filter slits distributed on the wall surface, allowing the squeezed-out water to permeate and be discharged while preventing solid mud cake from passing through. The discharge pipe 504 is directly connected to the interior of the extrusion cylinder 401 to concentrate the water content... Copper slurry is discharged directly into the extrusion cylinder 401 from the discharge pipe 504; the spiral extrusion plate 402 has a spiral blade structure and is rotatably disposed in the extrusion cylinder 401; one end of the rotating shaft of the spiral extrusion plate 402 extends into the lower support cylinder 101, and a driven bevel gear 403 is fixedly installed at its end; the driven bevel gear 403 meshes with the driving bevel gear 508 at the lower end of the first transmission shaft 507 at a 90-degree angle, converting the vertical rotational motion of the first transmission shaft 507 into the horizontal rotational motion of the spiral extrusion plate 402; The helical spacing of the spiral extrusion plate 402 gradually decreases along the discharge direction. When the copper-containing slurry enters the extrusion cylinder 401 directly from the discharge pipe 504, the rotating spiral extrusion plate 402 pushes the slurry axially towards the discharge end. As the helical spacing gradually decreases, the volume occupied by the slurry is gradually compressed, and the extrusion pressure increases step by step. The residual water in the slurry is squeezed out and permeates through the cylinder wall of the extrusion cylinder 401 into the drainage cylinder 105. At the same time, the waste water that has passed through the cylinder wall after centrifugal separation by the elastic filter cone 502 is also removed. Water flows down the inner wall of the guide cone 102 to the top of the guide baffle 106, and is then guided into the drain cylinder 105 via the guide baffle 106. The two parts of wastewater merge in the drain cylinder 105 and are discharged from the end of the drain cylinder 105. Since the length of the drain cylinder 105 is shorter than the length of the extrusion cylinder 401, the separated wastewater is discharged from the end of the drain cylinder 105 first, while the copper-containing mud cake, after being fully extruded and dehydrated, is discharged from the end of the extrusion cylinder 401 extending from the end of the drain cylinder 105, thus achieving the separate discharge of wastewater and mud cake.

[0060] The usage process of the integrated equipment for deep treatment and reuse of copper smelting wastewater proposed in this embodiment is as follows:

[0061] Copper-containing smelting wastewater is introduced into the upper support cylinder 104 via a spiral inlet pipe 200 and outlet hole 107 in a tangential spiral recirculation manner. The high-speed spiral water flow impacts the inclined blades of the impeller assembly 501, driving the impeller assembly 501 to rotate. The rotation of the impeller assembly 501 drives the first drive shaft 507 to rotate synchronously, which in turn drives the second support ring 505 and the elastic filter cone 502 fixed thereon to rotate at high speed. Guided by the spiral guide vanes 506, the wastewater enters the elastic filter cone 502 through the upper opening. Under centrifugal force, copper-containing suspended particles are thrown towards the inner wall of the elastic filter cone 502. Water passes through the microporous filter wall and enters the annular gap space between the guide cone 102 and the elastic filter cone 502; the filtered wastewater is blocked by the inner wall of the guide cone 102 and flows downward along the inner wall of the guide cone 102, falling to the top of the guide baffle 106, and flowing into the drain cylinder 105 under the guidance of the guide baffle 106; during rotation, the arc-shaped protrusion 509 on the outer edge of the second support ring 505 periodically presses the cam 5033 in the cleaning component 503 fixed on the inner wall of the guide cone 102. After being pressed, the cam 5033 drives the active connecting rod 5034 to deflect, and the active connecting rod 5034 drives... The second drive shaft 5031 rotates, thereby driving the passive connecting rod 5035 and the striking block 5037 to shift towards the outer wall of the elastic filter cone 502 and strike it, while stretching the spring 5036; after the arc-shaped protrusion 509 disengages from the cam 5033, the spring 5036 rebounds and drives the passive connecting rod 5035, the second drive shaft 5031, the active connecting rod 5034 and the cam 5033 to reset, thus periodically striking to maintain unobstructed filtration; the concentrated copper-containing slurry slides down the conical surface of the elastic filter cone 502 and is directly discharged into the extrusion cylinder 401 through the discharge pipe 504; the active bevel gear 5 at the lower end of the first drive shaft 507... 08 drives the driven bevel gear 403 to rotate, which in turn drives the spiral extrusion plate 402 to push the copper-containing slurry axially and extrude it step by step. The squeezed-out water seeps out through the cylinder wall of the extrusion cylinder 401 into the drainage cylinder 105, where it merges with the centrifugally separated wastewater introduced by the guide baffle 106 and is discharged from the end of the drainage cylinder 105. Since the length of the drainage cylinder 105 is shorter than that of the extrusion cylinder 401, the separated wastewater is discharged from the end of the drainage cylinder 105 first. The copper-containing slurry cake, which has been fully extruded and dehydrated, then extends out of the extrusion cylinder 401 from the end of the drainage cylinder 105 and is discharged, thus completing the integrated process of deep wastewater treatment and copper resource recovery.

[0062] Example 2

[0063] like Figures 1 to 9 As shown, this embodiment of the integrated equipment for deep treatment and reuse of copper smelting wastewater optimizes the setting of the cleaning component 503 based on embodiment 1.

[0064] In this embodiment, the cleaning components 503 are arranged in multiple layers along the axial direction of the inner wall of the guide cone 102, with each layer corresponding to the height position of a second support ring 505. Multiple sets of cleaning components 503 are evenly arranged circumferentially in each layer, and the cleaning components 503 of adjacent layers are staggered circumferentially, so that the elastic filter cone 502 can be subjected to intermittent knocking action at different heights and different circumferential positions, ensuring that the cleaning coverage of the entire filter surface is more uniform. At the same time, the arc length and protrusion height of the arc-shaped protrusions 509 in different layers can be set to different values. The arc length of the arc-shaped protrusions 509 on the upper second support ring 505 is longer and the protrusion height is larger, so that the knocking frequency and knocking force of the cleaning components 503 at the corresponding position are higher. The arc length of the arc-shaped protrusions 509 on the lower second support ring 505 is shorter and the protrusion height is smaller, corresponding to a moderate knocking frequency and a smaller force.

[0065] The usage process of the integrated equipment for deep treatment and reuse of copper smelting wastewater proposed in this embodiment is as follows: The usage process is basically the same as that in Embodiment 1. The difference is that during the cleaning process, each layer of cleaning components 503 performs differentiated cleaning of the elastic filter cone 502 in different areas and layers according to the parameter differences of the arc-shaped protrusions 509, ensuring that the entire filter surface can maintain good permeability under different working conditions.

[0066] Example 3

[0067] like Figures 1 to 9 As shown, this embodiment of the integrated equipment for deep treatment and reuse of copper smelting wastewater optimizes the structure of the screw extrusion mechanism 400 based on embodiment 1.

[0068] In this embodiment, the spiral spacing of the spiral extrusion plate 402 adopts a three-stage gradual design: the spiral spacing of the feeding section is the largest, which facilitates the smooth reception and initial conveying of copper-containing slurry directly discharged from the discharge pipe 504; the spiral spacing of the intermediate transition section is moderate, which realizes the initial compression and dewatering of the slurry; the spiral spacing of the discharge section is the smallest, which realizes the deep compression and dewatering of the slurry; in addition, the extrusion cylinder 401 has filtration areas spaced along the axial direction on its cylinder wall, and the filtration areas are densely covered with micropores or filter slits, so that the water squeezed out by the spiral extrusion plate 402 can be timely permeated and discharged into the drainage cylinder 105.

[0069] The process of using the integrated equipment for deep treatment and reuse of copper smelting wastewater proposed in this embodiment is as follows: The concentrated copper-containing slurry is discharged directly into the extrusion cylinder 401 from the bottom end of the elastic filter cone 502 through the discharge pipe 504. After that, it goes through three stages in sequence: preliminary conveying in the feeding section, preliminary compression in the intermediate transition section, and deep extrusion in the discharge section. The water in the copper-containing slurry is squeezed out step by step and permeates into the drainage cylinder 105 through the filtration area on the cylinder wall of the extrusion cylinder 401. The permeated water and the centrifugally separated wastewater introduced by the guide baffle 106 merge in the drainage cylinder 105 and are discharged together from the end of the drainage cylinder 105. The copper-containing sludge cake that has been fully dehydrated is discharged from the end of the drainage cylinder 105 from the extrusion cylinder 401, realizing the separate and orderly discharge of wastewater and sludge cake.
