Description

Technical Field

[0001] This invention relates to the field of anode copper waste residue recycling technology, specifically to equipment for the resource recovery of waste residue from the anode copper production process. Background Technology

[0002] Anode copper is an important intermediate product in the copper smelting process, and its production inevitably generates waste slag containing various heavy metal elements such as copper, lead, and zinc. This waste slag still contains valuable metal components that can be recycled, and its resource recycling treatment has significant economic and environmental value. The resource recycling of waste slag usually requires first crushing large pieces of waste slag to achieve a suitable particle size before subsequent sorting and extraction processes. In the crushing stage, mechanical crushing and roller milling are widely used. The crushed waste slag is then graded by particle size using screening equipment to meet the feeding requirements of different recycling processes.

[0003] However, the crushing process generates a large number of fine dust particles containing heavy metals, which are easily dispersed into the surrounding environment by airflow. Traditional crushing equipment usually lacks effective dust control measures or only uses simple sealing covers to block dust, which cannot fundamentally prevent the escape of dust. Although some existing dust removal equipment is equipped with filtration devices, the filter elements are easily clogged by dust during long-term operation, resulting in a decrease in filtration efficiency. Frequent shutdowns are required to clean or replace the filter media, which affects the continuous operating efficiency of the equipment.

[0004] Therefore, there is an urgent need for a recycling device that can effectively suppress dust dispersion during the waste crushing process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a resource recovery device for waste residue from the production process of anode copper. By combining negative pressure suction and centrifugal separation with filter cloth filtration and self-vibrating dust removal mechanism, the device effectively suppresses the diffusion of heavy metal-containing dust during the crushing process and achieves the resource recovery of dust.

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

[0007] This invention provides a resource recovery device for waste residue from the anode copper production process, comprising:

[0008] The main crushing and recycling mechanism includes a main chamber, with a feed hopper and a discharge hopper respectively arranged on the side walls of the main chamber, a drive motor unit arranged on the top of the main chamber, and a crushing mechanism arranged on the bottom of the main chamber;

[0009] A main drive shaft is disposed inside the main compartment and is connected to the drive motor unit for transmission.

[0010] A flow guiding mechanism is disposed inside the main chamber and above the crushing mechanism. The flow guiding mechanism includes a flow guide shroud and turbine blades. The flow guide shroud is connected to the main drive shaft via a support frame. The turbine blades are disposed inside the flow guide shroud and above it. The main drive shaft drives the turbine blades to rotate to generate a spiral upward airflow and form a negative pressure area above the crushing mechanism.

[0011] A filtration mechanism is disposed above the flow guiding mechanism, and the filtration mechanism includes a filter cloth for intercepting dust particles that rise with the airflow.

[0012] Preferably, the outer edge of the flow guide hood is provided with an annular dust collection platform. The outer side of the dust collection platform is sealed to fit the inner wall of the main chamber, and the dust collection platform is connected to the input end of the discharge hopper. The dust that falls after being filtered by the filter cloth settles to the top of the flow guide hood and is collected by the dust collection platform. As the flow guide hood rotates, it is discharged from the discharge hopper. The dust collection platform is used to receive the dust particles after centrifugal separation and filtration and transport them to the discharge hopper for centralized recycling.

[0013] Preferably, the input end of the discharge hopper is provided with an elastic scraper, the inner side of the elastic scraper is attached to the outer side of the dust collection platform and the attached part is provided with a brush, the elastic scraper is inclined relative to the dust collection platform, and the two form an acute angle when the guide hood rotates in the forward direction and an obtuse angle when the guide hood rotates in the reverse direction. The elastic scraper is used to effectively scrape off the dust accumulated on the dust collection platform and guide it into the discharge hopper when the guide hood rotates in the reverse direction.

[0014] Preferably, the crushing mechanism includes a main crushing roller and a secondary crushing roller. A three-stage screening mechanism is provided below the main chamber. The crushed waste falls into the three-stage screening mechanism for grading and screening. The crushing mechanism and the three-stage screening mechanism work together to achieve crushing and grading of the waste according to particle size.

[0015] Preferably, the filtration mechanism further includes a T-shaped ring plate, which is sleeved on the outer side of the top of the filter cloth. A first sliding rod is symmetrically arranged on one side of the top of the outer side of the T-shaped ring plate, and a support slider is symmetrically arranged on the other side. A second protrusion is symmetrically arranged at the bottom of the outer side of the T-shaped ring plate below the two first sliding rods. The T-shaped ring plate is used to provide top support for the filter cloth and transmit vibration excitation force through the second protrusion.

[0016] Preferably, an outer limiting ring is fitted on the top of the outer side of the T-shaped ring plate, the first sliding rod passes through the first displacement holes on both sides of the outer limiting ring, the supporting slider slides in the supporting grooves on the other two sides of the outer limiting ring, and a first elastic spacer is provided on the outer side of the T-shaped ring plate and sealed to the bottom of the outer limiting ring. The outer limiting ring is used to constrain the T-shaped ring plate and guide it to slide radially.

[0017] Preferably, a support ring is provided on the inner top of the main chamber, and a plurality of first protrusions are provided on the inner side of the support ring. The number of the first protrusions is odd and they are asymmetrically distributed. The bottom of the outer limiting ring is rotatably connected to the top of the support ring. The second protrusion on the T-shaped ring plate rotates and alternately squeezes the first protrusions. The odd number and asymmetrical arrangement of the first protrusions are used to make the filter cloth alternately subjected to extrusion forces in different directions during rotation, thereby achieving radial bidirectional vibration.

[0018] Preferably, an inner support ring plate is provided on the inner side of the filter cloth, and the inner support ring plate is fastened to the filter cloth. A plurality of second sliding rods are radially arranged on the inner side of the inner support ring plate. An inner limiting ring is provided on the main drive shaft. The second sliding rods pass through the second displacement hole on the inner limiting ring and can slide radially. A through hole is provided between the inner support ring plate and the filter cloth. The inner support ring plate and the second sliding rods are used to radially slide the filter cloth to the main drive shaft and provide an internal discharge channel for the filtered airflow.

[0019] Preferably, a return spring is provided at one end of the second slide rod that is in contact with the main drive shaft, and the other end of the return spring abuts against the main drive shaft. When the filter cloth is compressed and displaced radially along the main drive shaft, the return spring provides a reverse return force and causes the filter cloth to vibrate. The return spring is used to provide a rebound force after the filter cloth is compressed and displaced radially, so that the filter cloth vibrates to automatically shake off the dust attached to the outside.

[0020] Preferably, a blade assembly is provided above the filtration mechanism. The blade assembly is fixed on the main drive shaft and located at the top inside the main chamber. A rotating ring is provided on the outer side of the blade assembly. The outer side of the rotating ring is embedded in the inner wall of the main chamber. The inner wall of the main chamber is provided with a support ring groove that matches the rotating ring.

[0021] The bottom of the inner support ring plate is provided with a second elastic spacer that is sealed to the outside of the main drive shaft, and the bottom of the filter cloth is simultaneously provided with a third elastic spacer.

[0022] The top of the main chamber is provided with a support cover, and the top of the support cover is connected to an air guide pipe. The drive end of the drive motor unit is provided with a transmission unit located inside the support cover. The transmission unit is connected to the main drive shaft. The airflow filtered by the filter cloth is guided by the blade group and discharged from the air guide pipe. During the discharge process, the transmission unit is cooled. The blade group and the air guide pipe are used to guide the clean airflow to be discharged in a directional manner and use the discharged airflow to perform air cooling and heat dissipation on the transmission unit.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0024] 1. This invention creates a negative pressure zone above the crushing mechanism by setting turbine blades and a guide shroud driven by the main drive shaft inside the main chamber. This allows the airflow containing heavy metal dust generated during crushing to be actively drawn upwards instead of escaping outwards. As the dust airflow spirals upwards inside the guide shroud, it is initially separated by the combined action of centrifugal force and gravity. Heavier particles settle to the dust collection platform, thus preventing the spread of dust to the external environment from the source.

[0025] 2. This invention sets an inclined elastic scraper at the input end of the discharge hopper and uses a brush to fit against the dust collection platform. By utilizing the switching of acute and obtuse angles between the elastic scraper and the dust collection platform when the guide hood rotates in both directions, dust is accumulated and directionally scraped off on the dust collection platform. The collected dust particles containing valuable metals are then guided into the discharge hopper for centralized recycling, thus taking into account both dust removal and resource utilization.

[0026] 3. This invention uses the second protrusion on the T-shaped ring plate and the odd number of asymmetrically distributed first protrusions on the support ring to alternately squeeze each other during rotation. In conjunction with the reset spring, the filter cloth generates bidirectional reciprocating vibration in the radial direction, automatically shaking off the dust attached to the outside. This effectively solves the problem of filter cloth clogging easily during long-term operation, reduces the frequency of downtime maintenance, and ensures the continuous and stable operation of the equipment.

It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof.

[0049] Example 1

[0050] like Figures 1 to 15 As shown, this embodiment provides a resource recovery device for waste residue from the anode copper production process, including:

[0051] The main crushing and recycling mechanism 200 includes a main bin 203. The side walls of the main bin 203 are respectively provided with a feed hopper 201 and a discharge hopper 202. The top of the main bin 203 is provided with a drive motor unit 204, and the bottom of the main bin 203 is provided with a crushing mechanism 600.

[0052] The main drive shaft 300 is located inside the main compartment 203 and is connected to the drive motor unit 204 for transmission.

[0053] The flow guiding mechanism 500 is located inside the main chamber 203 and above the crushing mechanism 600. The flow guiding mechanism 500 includes a flow guide shroud 501 and a turbine blade 504. The flow guide shroud 501 is connected to the main drive shaft 300 through a support frame 503. The turbine blade 504 is located above the inner wall of the flow guide shroud 501. The main drive shaft 300 drives the turbine blade 504 to rotate to generate a spiral upward airflow and form a negative pressure area above the crushing mechanism 600.

[0054] The filter mechanism 400 is disposed above the flow guiding mechanism 500. The filter mechanism 400 includes a filter cloth 407, which is used to intercept dust particles that rise with the airflow.

[0055] An annular dust collection platform 502 is provided on the outer edge of the flow guide hood 501. The outer side of the dust collection platform 502 is sealed and attached to the inner wall of the main chamber 203. The dust collection platform 502 is connected to the input end of the discharge hopper 202. The dust that falls after being filtered by the filter cloth 407 settles to the top of the flow guide hood 501 and is collected by the dust collection platform 502. It is discharged from the discharge hopper 202 as the flow guide hood 501 rotates. An elastic scraper 208 is provided at the input end of the discharge hopper 202. The inner side of the elastic scraper 208 is attached to the outer side of the dust collection platform 502 and the attached part is provided with a brush. The elastic scraper 208 is inclined relative to the dust collection platform 502. When the flow guide hood 501 rotates in the forward direction, the two form an acute angle. When the flow guide hood 501 rotates in the reverse direction, the two form an obtuse angle.

[0056] The crushing mechanism 600 includes a main crushing roller 601 and a secondary crushing roller 602. A three-stage screening mechanism 100 is provided below the main bin 203. The crushed waste falls into the three-stage screening mechanism 100 for grading and screening.

[0057] The filter mechanism 400 also includes a T-shaped ring plate 406, which is sleeved on the outer side of the top of the filter cloth 407. A first sliding rod 409 is symmetrically arranged on one side of the top of the outer side of the T-shaped ring plate 406, and a support slider 415 is symmetrically arranged on the other side. A second protrusion 408 is symmetrically arranged on the bottom of the outer side of the T-shaped ring plate 406 below the two sets of first sliding rods 409. An outer limiting ring 410 is sleeved on the top of the outer side of the T-shaped ring plate 406. The first sliding rods 409 pass through the first displacement holes 418 on both sides of the outer limiting ring 410, and the support slider 415 is positioned at the outer limiting ring. The outer side of the positioning ring 410 slides within the support grooves 417 on both sides. The outer side of the T-shaped ring plate 406 is provided with a first elastic spacer 411 that is sealed to the bottom of the outer limiting ring 410. The inner top of the main compartment 203 is provided with a support ring 401. The inner side of the support ring 401 is provided with several sets of first protrusions 402. The number of first protrusions 402 is odd and they are asymmetrically distributed. The bottom of the outer limiting ring 410 is rotatably connected to the top of the support ring 401. The second protrusion 408 on the T-shaped ring plate 406 rotates and alternately presses against the first protrusion 402.

[0058] The filter cloth 407 is provided with an inner support ring plate 420, which is fastened to the filter cloth 407. The inner support ring plate 420 is provided with a number of second slide rods 416 arranged radially on the inner side. The main drive shaft 300 is provided with an inner limiting ring 413. The second slide rods 416 pass through the second displacement hole 421 on the inner limiting ring 413 and can slide radially. A through hole is provided between the inner support ring plate 420 and the filter cloth 407.

[0059] The second slide rod 416 is provided with a return spring 414 at one end that is in contact with the main drive shaft 300. The other end of the return spring 414 abuts against the main drive shaft 300. When the filter cloth 407 is compressed and displaced in the radial direction of the main drive shaft 300, the return spring 414 provides a reverse return force and causes the filter cloth 407 to vibrate.

[0060] A blade assembly 404 is provided above the filter mechanism 400. The blade assembly 404 is fixed on the main drive shaft 300 and located at the top inside the main chamber 203. A rotating ring 405 is provided on the outer side of the blade assembly 404. The outer side of the rotating ring 405 is embedded in the inner wall of the main chamber 203. The inner wall of the main chamber 203 is provided with a support ring groove 403 that is adapted to the rotating ring 405.

[0061] The bottom of the inner support ring plate 420 is provided with a second elastic spacer 412 that is sealed and connected to the outside of the main drive shaft 300, and the bottom of the filter cloth 407 is simultaneously provided with a third elastic spacer 419.

[0062] The top of the main chamber 203 is provided with a support cover 205, and the top of the support cover 205 is connected to an air guide pipe 206. The drive end of the drive motor unit 204 is provided with a transmission unit 207 located inside the support cover 205. The transmission unit 207 is connected to the main drive shaft 300. The airflow filtered by the filter cloth 407 is guided by the blade group 404 and discharged from the air guide pipe 206. During the discharge process, the transmission unit 207 is cooled.

[0063] The usage process of the waste recycling equipment for the anode copper production process proposed in this embodiment is as follows:

[0064] Start the drive motor unit 204. The drive motor unit 204 drives the main drive shaft 300 to rotate through the transmission unit 207 inside the support cover 205. The main drive shaft 300 simultaneously drives the flow guiding mechanism 500 and the filter mechanism 400 to work together. The entire equipment only needs a single power source to complete multiple functions such as crushing and suction, centrifugal separation, filtration and dust removal and self-cleaning.

[0065] Waste residue is fed into the main chamber 203 from the feed hopper 201 and falls between the main crushing roller 601 and the secondary crushing roller 602 to be crushed. The squeezing force generated by the main crushing roller 601 and the secondary crushing roller 602 rotating in opposite directions gradually grinds large pieces of waste residue into fine particles. The crushed waste residue falls downward into the three-stage screening mechanism 100, and the particle size is classified through different levels of screens, so that waste residue of different particle sizes enters the corresponding collection area for subsequent classification and recycling.

[0066] During the crushing process, a large amount of dust particles containing heavy metals are generated. The main drive shaft 300 drives the guide shroud 501 and turbine blades 504 to rotate synchronously through the support frame 503. When the turbine blades 504 rotate, a spiral upward airflow is generated inside the guide shroud 501, creating a negative pressure area above the crushing mechanism 600. Since the feed hopper 201 is the main channel connecting the inside and outside of the main chamber 203, the negative pressure causes external air to flow into the main chamber 203 from the feed hopper 201, forming a directional airflow from the outside to the inside, effectively preventing the dust-laden airflow from escaping outward from the feed hopper 201. Under the action of negative pressure, the dust-laden airflow is drawn into the guide shroud 501 and spirals upward. During the spiral upward process, the dust particles are subjected to the combined effects of centrifugal force and gravity. Heavier particles are thrown outward and settle to the dust collection platform at the top of the guide shroud 501. On 502; the outer side of the dust collection platform 502 is sealed to the inner wall of the main chamber 203 to prevent dust from leaking from the gap between the dust collection platform 502 and the main chamber 203, ensuring that dust can only be discharged directionally through the discharge hopper 202; the dust is carried to the input end of the discharge hopper 202 as the guide hood 501 rotates. When the guide hood 501 rotates in the forward direction, the elastic scraper 208 and the dust collection platform 502 form an acute angle, and the brush of the elastic scraper 208 follows the direction of movement of the dust collection platform 502 and lies flat, and the dust continues to accumulate on the dust collection platform 502; when the guide hood 501 rotates in the reverse direction, the elastic scraper 208 and the dust collection platform 502 form an obtuse angle, and the brush stands up in the opposite direction to form an effective scraping angle, scraping off the dust accumulated on the dust collection platform 502 and guiding it into the discharge hopper 202 for discharge and recycling. The intermittent collection and discharge of dust is achieved through alternating forward and reverse operation;

[0067] Fine dust particles that are not centrifugally separated continue to rise with the airflow to the filtration mechanism 400, where they are intercepted by the outer side of the filter cloth 407. A third elastic spacer 419 at the bottom of the filter cloth 407 forms an elastic seal between adjacent filter cloth sheets, preventing dust-laden airflow from directly entering the inner side of the filter cloth 407 without filtration. Clean airflow passes through the filter cloth 407 and enters the through-hole connecting the inner support ring plate 420 and the filter cloth 407, continuing to rise along the inner space. A second elastic spacer 412 is provided at the bottom of the inner support ring plate 420, and this second elastic spacer 412 is sealed to the outer side of the main drive shaft 300, preventing unfiltered airflow from entering the inner space from the bottom, thus ensuring... All exhaust airflow is effectively filtered by filter cloth 407; the clean airflow is guided upward by blade assembly 404, which rotates and is embedded in the support ring groove 403 of the inner wall of main chamber 203 through rotating ring 405, ensuring the stability of blade assembly 404 rotation; the guided airflow enters the internal space of support cover 205 and is discharged from air guide pipe 206. During the process of airflow rising and flowing through the inside of support cover 205, the transmission unit 207 is cooled by air, and the flow of exhaust air carries away the heat generated by the operation of transmission unit 207, extending the service life of transmission unit 207 and realizing the multi-functional reuse of airflow.

[0068] Meanwhile, the main drive shaft 300 drives the inner limiting ring 413 to rotate. The inner limiting ring 413 drives the inner support ring plate 420 to rotate through the cooperation of the second displacement hole 421 and the second slide rod 416. The inner support ring plate 420 is fastened to the filter cloth 407, thereby driving the filter cloth 407 and the T-shaped ring plate 406 on its top outer side to rotate synchronously. The first elastic spacer 411 set on the outer side of the T-shaped ring plate 406 is sealed to the bottom of the outer limiting ring 410, maintaining a sealed state when the T-shaped ring plate 406 rotates and moves radially, preventing dust from entering the upper space from the gap between the T-shaped ring plate 406 and the outer limiting ring 410. The second protrusion 408, symmetrically arranged at the bottom of the T-shaped ring plate 406, makes pressing contact with the first protrusion 402 on the inner side of the support ring 401 as it rotates, so that the T-shaped ring plate 406 as a whole is subjected to a radial thrust along the main drive shaft 300, which drives the filter cloth 407 to rotate and move radially. During the radial displacement, the first slide rod 409 slides radially in the first displacement hole 418 of the outer limiting ring 410, and the support slider 415 slides in the support groove 417. The two work together to limit the T-shaped ring plate 406 to only translate in the radial direction without deflection, ensuring that the filter cloth 407 is uniformly stressed. At the same time, the second slide rod 409 slides radially in the first displacement hole 418 of the outer limiting ring 410, and the support slider 415 slides in the support groove 417. The two work together to limit the T-shaped ring plate 406 to translate only in the radial direction without deflection, ensuring that the filter cloth 407 is uniformly stressed. 16 slides radially within the second displacement hole 421, and the return spring 414 is compressed and stores energy; when the second protrusion 408 continues to rotate past the position of the first protrusion 402, the return spring 414 releases the rebound force, drives the filter cloth 407 to reverse reset and generate instantaneous vibration, shaking off the dust attached to the outside; since the number of the first protrusions 402 is odd and they are asymmetrically distributed, the other set of second protrusions 408 on the symmetrical plane of the first set of second protrusions 408 first contacts the adjacent first protrusions 402, and pushes the T-shaped ring plate 406 and the filter cloth 407 in the opposite direction to the previous extrusion direction, so that the filter cloth 407 generates reverse displacement and vibration in the radial direction; As the T-shaped ring plate 406 continues to rotate, the two sets of second protrusions 408 alternately contact the first protrusions 402 at different positions and repeatedly squeeze and release in different directions, causing the filter cloth 407 to generate continuous bidirectional alternating vibration in the radial direction, realizing the self-cleaning function of the filter cloth 407, continuously shaking off dust, preventing the filter cloth 407 from being blocked due to dust accumulation, and ensuring the long-term stability of filtration efficiency; the shaken-off dust slides down along the conical outer wall of the guide hood 501 under the action of gravity and settles into the dust collection platform 502, and is finally discharged and recycled through the discharge hopper 202 as the guide hood 501 rotates, realizing the resource recycling of valuable metals in the dust particles.

[0069] Example 2

[0070] like Figure 2As shown, this embodiment provides a waste recycling device for the anode copper production process. The outlet end of the gas guide pipe 206 can be connected to an external cyclone separator to perform secondary separation of the exhaust gas to recover ultrafine metal particles. The discharge hopper 202 can be connected to a sealed collection container to prevent dust from spreading again during the collection process. The drive motor unit 204 can be configured with a frequency converter to adjust the speed of the main drive shaft 300 in real time according to the feed rate and dust concentration. The speed is reduced to save energy under low load and increased to enhance the negative pressure adsorption capacity under high load. In the scenario of multiple devices connected in parallel, the gas guide pipes 206 of each device can be collected into a unified exhaust gas treatment system to achieve centralized management.
