Description

Technical Field

[0001] This invention relates to the field of metal waste recycling and treatment, specifically a safe recycling device for polymetallic waste residue. Background Technology

[0002] During the smelting and processing of metals from ores or waste materials, after the main metal is extracted, other metals and impurities cannot be completely separated and eventually enter the waste residue. Other useful metals may also remain in the waste residue. Extracting such multi-metal waste residue can reduce some of the resource waste. Currently, when recycling multi-metal waste residue, a certain amount of treatment liquid is usually added. The treatment liquid reacts with the metals in the metal waste residue, converting the metals into metal ions that dissolve in the treatment liquid and are effectively separated from the impurities.

[0003] Normally, the metal waste to be treated is poured into a treatment tank for centralized soaking. At the same time, in order to improve the reaction rate between the metal waste and the treatment liquid, a second agitator is often used to stir the metal waste in the treatment tank, thereby increasing the contact area between the second agitator and the treatment liquid. However, in actual implementation, due to the large mass of the metal waste, the metal waste remains at the bottom of the treatment tank when the second agitator is stirring, and it is not possible to fully disperse the metal waste in the treatment tank to react with the treatment liquid. Summary of the Invention

[0004] The purpose of this invention is to provide a safe recycling device for polymetallic waste residue, thereby solving the aforementioned technical problems. To achieve the above objectives, the present invention provides a safe recycling device for polymetallic waste residue, including a reaction vessel and a holding cylinder. The reaction vessel is fixedly installed on the ground by two sets of support legs, and a drain port is provided at its bottom. The upper opening is sealed by a sealing cover. The sealing cover is lifted and lowered by a lifting assembly at the top of the reaction vessel. The holding cylinder is installed at the bottom of the sealing cover and includes a rotating cylinder and a rotating tube. The rotating cylinder is rotatably installed at the bottom of the sealing cover and is driven to rotate by a rotating assembly on the sealing cover.

The upper end of the rotary drum is equipped with an intermittent discharge assembly and a first stirring assembly. The lower end of the rotary drum is equipped with multiple sets of second stirring assemblies at intervals along the vertical direction. Each set of second stirring assemblies includes multiple sets of second stirrers. Multiple sets of second stirrers in the same layer are arranged circumferentially inside the rotary drum, and their two ends are rotatably mounted on the rotary drum and the rotary tube, respectively.

Each set of second stirring assemblies is equipped with a set of screening screens at the bottom. The aperture of the multiple sets of screening screens decreases from top to bottom, and adjacent screening screens are fixedly connected by connecting columns. The screening screens are connected to the reaction vessel through a vibration assembly. When the rotary drum rotates, it drives the first stirring component to stir the metal waste slag at the top of the intermittent discharge component, and the transmission component drives multiple sets of second stirrers to rotate, and the vibration component drives multiple sets of screening screens to reciprocate and vibrate.

[0005] As a further embodiment of the present invention, the lifting assembly includes multiple sets of guide columns, a drive screw, and a first motor; The upper ends of multiple sets of guide columns are fixedly installed on the sealing cover, and the lower column body is slidably connected to the guide hole opened on the upper side of the reactor. The upper end of the drive screw is rotatably installed on the sealing cover and is driven to rotate by the first motor correspondingly set on the sealing cover. The upper side of the reactor is provided with a fixed inner nut that is threadedly connected to the corresponding drive screw.

[0006] As a further embodiment of the present invention, the sealing cover is provided with a ventilation pipe and a feed guide groove; The ventilation pipe is connected to the ventilation hole on the sealing cover, and the feed guide groove is connected to the feed inlet in the center of the sealing cover. The top of the pipe is sealed by a sealing flip cover.

[0007] As a further embodiment of the present invention, the rotary assembly includes a rotary gear ring, a drive gear, and a second motor; The rotary gear ring is coaxially fixedly installed on the outside of the rotary drum. The drive gear is located on one side of the rotary gear ring and meshes with it. The second motor is fixedly installed on the sealing cover and is used to drive the drive gear to rotate.

[0008] As a further embodiment of the present invention, the intermittent rotation assembly includes a fixed base and a rotary sealing plate; The fixed base includes a fixed tube and multiple sets of base plates. The fixed base is rotatably installed on the outside of the rotating tube, and its upper end is fixedly connected to the sealing cover. The multiple sets of base plates are fixedly installed at the bottom of the fixed tube. There is a discharge opening between adjacent base plates for metal waste to fall. The two ends of the rotating sealing plate are fixedly connected to the rotating tube and the rotating cylinder. The rotating sealing plate can seal the discharge opening.

[0009] As a further embodiment of the present invention, the first stirring assembly includes multiple sets of stirring claws, which are evenly arranged along the circumference of the rotating cylinder, and one end of the stirring claws is fixedly connected to the inner wall of the rotating cylinder.

[0010] As a further embodiment of the present invention, the second stirrer includes a stirring shaft and multiple sets of stirring columns, wherein the multiple sets of stirring columns are provided with stirring branch pipes that communicate with the liquid delivery channel inside the stirring shaft.

[0011] As a further embodiment of the present invention, the transmission assembly includes a fixed bevel gear and multiple sets of transmission bevel gears; The fixed bevel gear is coaxially mounted on the outside of the fixed shaft, and multiple sets of transmission bevel gears are coaxially mounted on the ends of the corresponding stirring shafts and mesh with the fixed bevel gear for transmission.

[0012] As a further embodiment of the present invention, the liquid delivery pipe is fixedly installed on the outer side of the rotating cylinder, and an inlet is provided at the end of the pipe away from the rotating cylinder.

[0013] As a further embodiment of the present invention, the vibration assembly includes a transmission rod, a return spring, a sliding guide wheel, and a fixing ring; Multiple sets of transmission rods are fixedly installed at the bottom of the connecting column. The reset spring is wound around the transmission rod body and is used to elastically transmit the transmission rod and the rotary drum. The sliding guide wheel is rotatably installed at the bottom of the transmission rod. The fixed ring is fixedly installed at the bottom of the reactor. Its upper end face is provided with a wave-shaped support surface for the sliding guide wheel to slide.

[0014] Compared with the prior art, the advantages of the present invention are: 1. The material container is connected to the sealing cover at the top of the reactor. When the operator puts in the metal waste, the lifting component moves the sealing cover and the material container at its bottom upwards, keeping the intermittent discharge component in the material container above the liquid surface. This prevents the metal waste from contacting the liquid and generating gas that could affect the operator's discharge during the process of putting the metal waste into the material container. When the sealing cover is lowered and the metal waste comes into contact with the liquid, the chemical gases generated by the reaction can be discharged through the vent on the sealing cover into the vent pipe for unified collection and treatment. 2. The rotation of the rotary drum drives the bottom support plate and the rotary sealing plate in the intermittent discharge assembly to alternate intermittently, so that the metal waste on the intermittent discharge assembly is intermittently discharged into the bottom screen when participating in the reaction, thus avoiding the accumulation of metal waste on the first screen and affecting the vibration of the screen. 3. During the reaction, the fully reacted metal waste is sieved through the mesh of the screening screen to the next layer of the screening screen due to the reduction in its particle size, and the reaction continues until the metal waste has completely reacted. Thus, metal waste participates in the reaction on each layer of the screening screen. 4. When different layers of the treated liquid react, the second stirrer rotates synchronously with the rotary drum, agitating the metal waste slag in the vibrating state of the screen. At the same time, the stirring shaft of the second stirrer can draw the treated liquid away from the rotary drum in the reactor through the liquid inlet of the liquid delivery pipe, and finally inject it into the rotary drum through the stirring branch pipe to participate in the reaction of the metal waste slag, thereby improving the flow of the treated liquid in the reactor.

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 , Figure 2 as well as Figure 3As shown in the embodiment of the present invention, a safe recycling device for polymetallic waste includes a reaction vessel 1 and a holding cylinder 8. The reaction vessel 1 is fixedly installed on the ground by two sets of support legs 2, and has a drain port at its bottom. Its upper opening is sealed by a sealing cover 3. The sealing cover 3 is raised and lowered by a lifting assembly 7 at the top of the reaction vessel 1. The holding cylinder 8 is installed at the bottom of the sealing cover 3 and includes a rotating cylinder 801 and a rotating pipe 802. The rotating cylinder 801 is rotatably installed at the bottom of the sealing cover 3 and is supported by the upper part of the sealing cover 3. The rotating component 4 drives the rotation, and the rotating tube 802 is coaxially arranged at the center of the rotating drum 801; the rotating drum 801 has a connecting groove on its side for processing and flow, and the upper end of the rotating drum 801 is provided with an intermittent discharge component 11 and a first stirring component. The lower end of the rotating drum 801 is provided with multiple sets of second stirring components at intervals along the vertical direction. Each set of second stirring components includes multiple sets of second agitators 13. The multiple sets of second agitators 13 in the same layer are arranged circumferentially in the rotating tube 802 inside the rotating drum 801, and their two ends rotate respectively. Installed on the rotary drum 801 and the rotary tube 802, the second agitator 13 has a liquid delivery channel for the processed liquid to pass through, and a liquid outlet for the processed liquid to be discharged. One end of multiple sets of second agitators 13 inserted into the rotary tube 802 is connected to the fixed shaft 17 inside the rotary tube 802 via a transmission assembly 12. One end of the second agitator 13 extending out of the rotary drum 801 is connected to the liquid delivery pipe 9 outside the rotary drum 801. The end of the agitator shaft 1301 of the second agitator 13 is coaxially and fixedly connected to the spiral rod 14 inside the liquid delivery pipe 9. Next, each set of second stirring components is provided with a set of screening screens 15 at the bottom. The aperture of the multiple sets of screening screens 15 decreases from top to bottom, and adjacent screening screens 15 are fixedly connected by connecting columns. The screening screens 15 are connected to the reactor 1 by a vibration component 16. When the rotary drum 801 rotates, it drives the first stirring component to stir the metal waste slag at the upper end of the intermittent discharge component 11. The transmission component 12 drives the multiple sets of second stirrers 13 to rotate, and the vibration component 16 drives the multiple sets of screening screens 15 to vibrate back and forth.

[0023] like Figure 1As shown, in this embodiment of the invention, the lifting assembly 7 includes multiple sets of guide columns 704, a drive screw 701, and a first motor 702. The upper ends of the multiple sets of guide columns 704 are fixedly installed on the sealing cover 3, and their lower column bodies are slidably connected to the guide holes opened on the upper side of the reactor 1. The upper end of the drive screw 701 is rotatably installed on the sealing cover 3 and is driven to rotate by the first motor 702 correspondingly provided on the sealing cover 3. The upper side of the reactor 1 is provided with a fixing inner nut 703 that is threadedly connected to the corresponding drive screw. The present invention achieves the lifting of the sealing cover 3... When moving up and down, the two sets of first motors 702 are started, driving the two sets of drive screws 701 and the fixed inner nut 703 to move vertically. At the same time, the two sets of guide posts 704 located on both sides of the sealing cover 3 slide to the corresponding guide holes when the sealing cover 3 is raised and lowered, guiding and positioning the movement of the sealing cover 3. The lifting component 7 can also be replaced by other components with the same function, such as using a telescopic cylinder to drive the drive screw 701 of the present invention.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment of the invention, the sealing cover 3 is provided with a ventilation pipe 6 and a feed guide 5. The ventilation pipe 6 is connected to the ventilation hole on the sealing cover 3, and the feed guide 5 is connected to the feed inlet in the center of the sealing cover 3. Its top is sealed by a sealing flip cover 501. In this invention, after the operator completes the entry of the metal waste, the feed inlet in the center of the sealing cover 3 can be sealed by the sealing flip cover 501. This allows the chemical gas generated by the contact between the metal waste in the container 8 and the processing liquid to be discharged from the ventilation hole into the ventilation pipe 6 for unified collection and treatment, thus preventing the reaction gas from leaking into the environment.

[0025] like Figure 2 , Figure 3 as well as Figure 4 As shown, in this embodiment of the invention, the rotary assembly 4 includes a rotary gear ring 403, a drive gear 402, and a second motor 401. The rotary gear ring 403 is coaxially fixedly installed on the outside of the rotary drum 801. The drive gear 402 is disposed on one side of the rotary gear ring 403 and meshes with the rotary gear ring 403. The second motor 401 is fixedly installed on the sealing cover 3 and is used to drive the drive gear 402 to rotate. When the sealing cover 3 is lowered to the lowest position, the second motor 401 can be started to drive the drive gear 402 to rotate, and the rotary gear ring 403 meshes and drives the rotary drum 801 to rotate continuously. Furthermore, the intermittent rotation assembly includes a fixed base and a rotary sealing plate 1103. The fixed base includes a fixed tube 1101 and multiple sets of base plates 1102. The fixed base is rotatably mounted on the outside of the rotary tube 802, and its upper end is fixedly connected to the sealing cover 3. The multiple sets of base plates 1102 are fixedly mounted on the bottom of the fixed tube 1101. A discharge opening for metal waste to fall is provided between adjacent base plates 1102. The two ends of the rotary sealing plate 1103 are fixedly connected to the rotary tube 802 and the rotary drum 801. The rotary sealing plate 1103 can seal the discharge opening. When the rotary drum 801 rotates, it drives the multiple sets of rotary sealing plates at the bottom of the base plates 1102. The plate 1103 rotates. When the rotary sealing plate 1103 rotates to the bottom of the bottom support plate 1102, the discharge opening is open, and the metal waste slag on the top of the fixed bottom support can fall to the bottom through the discharge opening. When the rotary sealing plate 1103 rotates to the bottom of the discharge opening, the rotary sealing plate 1103 continues to seal the discharge opening, so that the metal waste slag cannot fall further. The rotation of the rotary drum 801 realizes the intermittent opening and closing of the discharge opening, thereby ensuring that the metal waste slag in the intermittent rotating component is intermittently transported to the bottom screen 15 for further reaction, avoiding the one-time transport of a large amount of metal waste slag to the screen 15, which would affect the vibration reaction effect of the screen 15. Furthermore, the first stirring assembly includes multiple sets of stirring claws 10, which are evenly arranged around the circumference of the rotary drum 801. One end of each stirring claw 10 is fixedly connected to the inner wall of the rotary drum 801. When the rotary drum 801 rotates, the multiple sets of stirring claws 10 can simultaneously stir and mix the metal waste on the intermittent rotating assembly, allowing it to react further with the upper treatment liquid and assisting the metal waste to fall from the discharge opening.

[0026] like Figure 3 and Figure 4 As shown, in this embodiment of the invention, the second stirrer 13 includes a stirring shaft 1301 and multiple sets of stirring columns 1302. The multiple sets of stirring columns 1302 are provided with stirring branch pipes that communicate with the liquid delivery channel inside the stirring shaft 1301. In this invention, when the rotary drum 801 rotates, the stirring shaft 1301 of the second stirrer 13 is driven to rotate synchronously through the transmission assembly 12, so that the multiple sets of stirring columns 1302 outside the stirring shaft 1301 can stir the metal waste residue in the vibrating state of the screen 15, so that the metal waste residue can fully react with the treatment liquid. The transmission assembly 12 includes a fixed bevel gear 1201 and multiple sets of transmission bevel gears 1202. The fixed bevel gear 1201 is coaxially mounted on the outside of the fixed shaft 17, and the multiple sets of transmission bevel gears 1202 are coaxially mounted on the ends of the corresponding stirring shafts 1301 and mesh with the fixed bevel gear 1201 for transmission. When the rotary drum 801 drives the stirring shafts 1301 of the multiple sets of second stirrers 13 to rotate around the fixed shaft 17, the meshing of the fixed bevel gear 1201 and the transmission bevel gear 1202 drives the stirring shaft 1301 to rotate itself. Furthermore, the liquid delivery pipe 9 is fixedly installed on the outer side of the rotating cylinder, and an inlet is provided at the end away from the rotating cylinder 801. When the stirring shaft 1301 rotates, it can drive the spiral rod 14 inside the liquid delivery pipe 9 to rotate, drawing the treatment liquid away from the rotating cylinder 801 in the reactor 1 into the inlet of the liquid delivery pipe 9, and then transporting it along the liquid delivery channel inside the stirring shaft 1301. Finally, it is injected into the rotating cylinder 801 through the stirring branch pipe of the stirring column 1302 to participate in the reaction of the metal waste. In this way, the present invention forcibly improves the flow of the treatment liquid in the reactor 1, avoiding the problem of large deviation in the reaction ion concentration of the treatment liquid due to poor flowability of the treatment liquid in the reactor 1.

[0027] like Figure 3 and Figure 5 As shown, in this embodiment of the invention, the vibration assembly 16 includes a transmission rod 1601, a return spring 1602, a sliding guide wheel 1603, and a fixed ring 1604. Multiple sets of transmission rods 1601 are fixedly installed at the bottom of the connecting column. The return spring 1602 is wound around the transmission rod 1601 to elastically transmit the transmission rod 1601 to the rotary drum 801. The sliding guide wheel 1603 is rotatably installed at the bottom of the transmission rod 1601. The fixed ring 1604 is fixedly installed at the bottom of the reactor 1. Its upper end face is provided with a wave-shaped support surface for the sliding guide wheel 1603 to slide. In this invention, when the rotary drum 801 rotates, it drives the two sets of sliding guide wheels 1603 at the bottom to slide along the upper surface of the fixed ring 1604. Due to the wave-shaped undulation on the fixed ring 1604, the sliding guide wheel 1603 moves back and forth up and down during the sliding process, and is driven by the connecting column to drive multiple sets of screening screens 15 to vibrate back and forth.

[0028] In summary, this invention provides a material container 8 for holding metal waste slag inside the reactor 1. The material container 8 is composed of a rotating cylinder 801 and a rotating pipe 802. When the operator puts in the metal waste, the lifting component 7 moves the sealing cover 3 and the material container 8 at its bottom upwards, keeping the intermittent discharge component 11 inside the material container 8 above the liquid surface. This prevents the metal waste from contacting the liquid and generating gas that could affect the operator's discharge during the process of putting the metal waste into the material container 8. When the sealing cover 3 descends, the chemical gas generated by the contact between the metal waste and the liquid can be discharged through the ventilation hole on the sealing cover 3 into the ventilation pipe 6 for unified collection and treatment. When the metal waste paper comes into contact with the processing liquid, the rotation of the rotary drum 801 drives the bottom support plate 1102 and the rotary sealing plate 1103 in the intermittent discharge assembly 11 to intermittently alternate, so that the metal waste on the intermittent discharge assembly 11 is intermittently discharged into the bottom screen 15 when participating in the reaction, and reacts in different layers of the processing liquid. When the second agitator 13 rotates with the rotary drum 801, its own rotation agitates the metal waste in the vibrating state of the screen 15. At the same time, when the agitator shaft 1301 of the second agitator 13 rotates, it can draw the processing liquid away from the rotary drum 801 in the reaction vessel 1 through the liquid inlet of the liquid delivery pipe 9, and finally inject it into the rotary drum 801 through the agitator branch pipe to participate in the reaction of the metal waste, improve the flow of the processing liquid in the reaction vessel 1. The fully reacted metal waste is screened into the next layer of screen 15 through the mesh of the screen 15 due to the reduction of its particle size during the reaction, and continues to react until the metal waste is completely reacted.

[0029] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
