Description

Technical Field

[0001] The present invention belongs to the field of lead-zinc waste slag smelting equipment, and more specifically, relates to a lead-zinc smelting waste slag comprehensive utilization reaction device and a use method thereof. Background Art

[0002] In the lead and zinc smelting industry, the treatment of lead and zinc smelting waste slag has always been a key and extremely challenging issue. The lead and zinc smelting process produces a large amount of waste slag with complex composition. It not only contains heavy metals such as lead and zinc, but may also contain a variety of other valuable metals and harmful substances. Lead and zinc smelting waste slag actually contains a large amount of recyclable metal resources, such as lead, zinc, iron, etc. According to relevant data statistics, the lead and zinc content in certain waste slags can reach a certain industrial grade after reasonable recovery, and has high economic value. However, due to the lack of efficient comprehensive utilization technology and equipment, these valuable metals have been abandoned for a long time, resulting in a huge waste of resources, which runs counter to the current concept of sustainable development.

[0003] The current lead-zinc waste slag smelting equipment has been found to have at least the following technical problems:

[0004] First, lead-zinc smelting waste contains a large amount of recyclable metal resources, such as lead, zinc, and iron. Relevant data show that the lead and zinc content in certain waste residues can reach a certain industrial grade after reasonable recovery, and have high economic value. However, due to the lack of effective comprehensive utilization technology and equipment, these valuable metals have been abandoned for a long time, which not only causes a huge waste of resources, but also increases the dependence of lead-zinc smelting enterprises on new ore raw materials, thereby increasing production costs. The device of the present invention utilizes a metal recovery mechanism to achieve the recovery of valuable metals such as lead and zinc from waste residues, thereby improving resource utilization, reducing resource waste, and reducing the cost of enterprises to obtain raw materials, which meets the requirements of sustainable resource development.

[0005] Second, lead and zinc smelting waste is rich in various heavy metals such as lead, zinc, cadmium, mercury, and harmful substances such as arsenic. The traditional stacking or landfill treatment method causes these heavy metals to continuously migrate and diffuse into the surrounding soil and water bodies under the natural effects of rainwater erosion, soil infiltration, etc. Summary of the Invention

[0012] A method for using a reaction device for comprehensive utilization of lead-zinc smelting waste residues, comprising the reaction device for comprehensive utilization of lead-zinc smelting waste residues according to any one of claims 1 to 9, comprising the following steps:

[0013] S1: The waste residue to be processed is fed into the kiln barrel from the feed port in the kiln tail. After the fuel in the combustion chamber is adjusted, the device is started. The DC motor drives the first transmission shaft to rotate. The second flat gear on the first transmission shaft engages with the first transmission belt to drive the first transmission belt to operate. The first transmission belt drives the third flat gear engaged with it to rotate, so that the second transmission shaft fixed on the third flat gear rotates synchronously. The second transmission shaft engages with the large gear ring through the first flat gear, driving the large gear ring to rotate, so that the kiln barrel fixed on the large gear ring starts to rotate. The kiln barrel is tilted at a certain angle. The waste residue in the kiln barrel continuously climbs along the inner wall under the combined action of the friction force of the inner wall of the barrel and its own gravity, and then falls and rolls due to the action of gravity, presenting a state of fusion of spiral rolling and axial propulsion, so that the waste residue can fully contact with the heat source in a high-temperature environment.

[0014] S2: The second transmission shaft rotates, causing the fifth spur gear fixed thereon to rotate. The fifth spur gear meshes with the second transmission belt, driving the second transmission belt to rotate, causing the fourth spur gear and the third transmission shaft to rotate. The rotation of the third transmission shaft drives the reciprocating power supply device fixed thereon to rotate. The reciprocating power supply device rotates to a predetermined position, and the shift lever on the multi-link device is shifted by the stop lever on the stop lever fixing plate. The limit slider in the reciprocating power supply device releases the limit on the sliding switch. The sliding switch falls under the cross slot in the reciprocating power supply device due to gravity and is connected to the bottom circuit, causing the upper electromagnet device to be de-energized and the lower electromagnet device to be energized. The energized electromagnet device at the lower end attracts the metal-containing waste slag in the kiln drum, and the de-energized electromagnet device at the upper end loses its attraction force, causing the metal waste slag on it to fall into the collection device. The scraper on the collection device scrapes off the waste slag remaining on the electromagnet device. The metal-containing waste slag passes through the connection between the collection device and the metal waste storage drum and falls into the metal waste storage drum.

[0015] S3: The third transmission shaft rotates, and through the meshing of the first bevel gear fixed thereon with the second bevel gear and the third bevel gear, the three bevel gears are driven to rotate synchronously. When the third bevel gear rotates, the fourth transmission shaft drives the stirring device fixing frame and the spiral stirring plate connected to it to rotate, and the rotation direction of the spiral stirring plate is opposite to that of the kiln barrel. The spiral stirring plate stirs the waste slag in the opposite direction in the kiln barrel, and the treated waste slag finally falls into the waste slag storage barrel, waiting for the staff to dispose of it harmlessly.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, by providing a metal recovery mechanism, efficient recovery of magnetic metals in lead-zinc smelting waste slag is achieved. In the mechanism, the electromagnet device operates in an orderly manner under the control of a reciprocating power-on device. When the device is running, the sliding conversion switch in the reciprocating power-on device moves in a cross slide, periodically changing the power-on state of the electromagnet device. Two groups of electromagnet devices are alternately energized, one group is energized to adsorb magnetic metals such as lead and zinc in the waste slag, and the other group is de-energized to allow the adsorbed metals to fall into a collection device. In this way, the valuable metals in the waste slag are fully recovered, which greatly improves the comprehensive utilization rate of resources and reduces resource waste.

[0018] In the present invention, a stirring mechanism is provided, and its core component, the spiral stirring plate, rotates continuously in the kiln barrel. During actual operation, the spiral stirring plate rotates at a specific speed and direction, and continuously turns over the waste slag in the kiln barrel. On the one hand, this turning makes the waste slag more evenly heated inside the kiln barrel, greatly increases the contact area between the waste slag and the reaction reagent, and allows the chemical reaction to proceed more fully, thereby significantly accelerating the reaction speed and effectively improving the overall reaction efficiency. On the other hand, in a high-temperature environment, the continuous stirring of the spiral stirring plate effectively prevents the sticking and ringing of the waste slag, which not only avoids the obstruction of the reaction process due to the agglomeration of the waste slag, but also eliminates the risk of clogging the equipment pipeline, effectively ensuring that the reaction device can operate stably, thereby reducing the frequency of equipment failures and reducing the maintenance cost of the equipment.

[0019] In the present invention, a rotary drive mechanism is provided to provide powerful power for the treatment of lead-zinc smelting waste slag. The mechanism uses a DC motor as a power source and drives the kiln drum to rotate stably through the coordinated transmission of a series of transmission shafts, flat gears and transmission belts. During the rotation of the kiln drum, the waste slag presents a unique motion state in the drum that combines spiral rolling with axial propulsion. This motion mode enables the waste slag to move fully in all directions in the kiln drum, achieves uniform mixing between materials, and greatly improves the heat transfer efficiency. In an environment of efficient heat transfer, chemical reactions can be carried out more fully, greatly improving the treatment effect of lead-zinc smelting waste slag, ensuring that the reaction is both sufficient and efficient, thereby laying a solid foundation for improving the quality of the final product. The products produced are of better quality and more in line with industrial application requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A metal recovery mechanism is provided inside the kiln barrel 12. The metal recovery mechanism is used to absorb and separate magnetic metals from the lead-zinc smelting waste slag to achieve resource recovery and pre-treat the waste slag to reduce interference with subsequent processes. A stirring mechanism is provided inside the kiln barrel 12. The stirring mechanism is used to continuously turn over the waste slag in the kiln barrel 12 so that the waste slag is evenly heated inside the kiln barrel 12 and to prevent the waste slag from sticking and ringing. A rotary drive mechanism is provided on the kiln barrel 12. The rotary drive mechanism is used to drive the rotation of the kiln barrel 12 and bring the waste slag from the feed port to the discharge port.

[0033] In this embodiment, Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, the metal recovery mechanism includes a baffle fixing plate 45, on which two baffles are provided, and two sets of limit sliders 33 are provided in the slide groove opened by the reciprocating power supply device 44. The two sets of limit sliders 33 are used to limit the sliding conversion switch 34. The two sets of limit sliders 33 are both provided with a multi-link device 32, which is used to control the limit slider 33 to release the limit slider 33 from limiting the sliding conversion switch 34. The two sets of multi-link devices 32 are both provided with a lever. The third transmission shaft 28 is rotatably mounted on the rod fixing plate 45, and the fourth flat gear 27 is fixedly mounted on the third transmission shaft 28. The circumferential surface of the fourth flat gear 27 is meshed with the second transmission belt 26, and the inner wall of the second transmission belt 26 is meshed with the fifth flat gear 46. The second transmission shaft 25 is fixedly mounted on the fifth flat gear 46. The kiln tube 12 is provided with a kiln tail 13, and the kiln tail 13 is provided with a metal scrap storage cylinder 18. A waste slag storage cylinder 17 is provided on the side of the metal scrap storage cylinder 18. The metal scrap storage cylinder 1 8 is connected to the collecting device 16, and the metal waste storage barrel 18 is used to store the metal waste collected by the metal recycling mechanism. During operation, when the second transmission shaft 25 drives the reciprocating power supply device 44 to rotate to a predetermined position, the shift lever provided on the multi-link device 32 is shifted by the stop lever provided on the stop lever fixing plate 45, driving the limit slider 33 in the reciprocating power supply device 44 to release the limit on the sliding conversion switch 34. The sliding conversion switch 34 will fall under the cross slide groove provided in the reciprocating power supply device 44 due to gravity and be connected to the circuit at the bottom, so that the upper electromagnet device 31 is powered off and the lower electromagnet device 31 is powered on, so that the electromagnet device 31 that contacts the waste slag at the lower end can absorb the waste slag containing metal in the kiln tube 12. The upper electromagnet device 31 is powered off, so that the metal waste slag that has lost its adsorption force just falls into the collecting device 16, and the scraper provided on the collecting device 16 can also scrape off the waste slag remaining on the electromagnet device 31, thereby realizing the separation and collection of metal waste slag.

[0034] In this embodiment, Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, the stirring mechanism includes a discharge port fixing plate 47, which is fixedly installed in the kiln tail 13, and a gear fixing frame 37 is fixedly installed on the discharge port fixing plate 47. The second bevel gear 38 is rotatably installed on the gear fixing frame 37. The circumferential surface of the second bevel gear 38 is meshed with the first bevel gear 36 and the third bevel gear 39. The first bevel gear 36 is fixedly installed on the third transmission shaft 28, and the third bevel gear 39 is provided with a fourth transmission shaft 41. The stirring device fixing frame 42 is fixedly installed on the fourth transmission shaft 41. The stirring device fixing frame 42 is fixedly connected to the spiral stirring plate 43. During operation, the third transmission shaft 28 rotates to drive the first bevel gear 36, the second bevel gear 38 and the third bevel gear 39 that are meshed with each other to rotate synchronously. The third bevel gear 39 drives the spiral stirring plate 43 to rotate through the fourth transmission shaft 41, and the rotation direction of the spiral stirring plate 43 is opposite to that of the kiln tube 12, so that the waste slag in the kiln tube 12 is continuously turned over, so that the waste slag is heated more evenly, thereby accelerating the reaction of the waste slag with the internal reaction reagent.

[0035] In this embodiment, Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, the rotary drive mechanism includes a first transmission shaft 21, which is fixedly connected to the DC motor through the output shaft, and a second spur gear 22 is fixedly mounted on the first transmission shaft 21, and a first transmission belt 23 is meshed on the circumferential surface of the second spur gear 22, and a third spur gear 24 is meshed on the first transmission belt 23, and the third spur gear 24 and the second transmission shaft 25 are fixedly mounted, and a first spur gear 19 is fixedly mounted on the second transmission shaft 25, and the first spur gear 19 is meshed with the large ring gear 15. During operation, the motor drives the first transmission shaft 21 to rotate through the output shaft, and the first transmission shaft 21 drives the large ring gear 15 to rotate, so that the kiln drum 12 fixedly mounted on the large ring gear 15 also rotates synchronously. Since the kiln drum 12 is designed to be inclined at a certain angle, the waste slag in the kiln drum 12 is in a state of spiral tumbling and axial propulsion. This composite motion enables the waste slag to fully contact the heat source in a high-temperature environment, thereby achieving uniform mixing, efficient heat transfer and chemical reaction between materials.

[0036] Working principle:

[0037] In the first step, the staff put the waste slag to be processed into the kiln barrel 12 from the feed port in the kiln tail 13, adjust the fuel in the combustion chamber and start the device. At this time, the DC motor drives the first transmission shaft 21 to rotate, and the second flat gear 22 on the first transmission shaft 21 engages with the first transmission belt 23, driving the first transmission belt 23 to operate. The first transmission belt 23 in turn drives the third flat gear 24 engaged therewith to rotate, thereby causing the second transmission shaft 25 fixed on the third flat gear 24 to rotate synchronously. The second transmission shaft 25 engages with the large ring gear 15 through the first flat gear 19, driving the large ring gear 15 to rotate, thereby causing the kiln barrel 12 fixed on the large ring gear 15 to start rotating. Since the kiln barrel 12 is tilted at a certain angle, during the rotation process, the waste slag in the kiln barrel 12 continuously climbs along the inner wall under the combined action of the friction force of the inner wall of the barrel and its own gravity, and then falls and rolls due to the action of gravity, presenting a state of fusion of spiral rolling and axial propulsion, so that the waste slag can fully contact the heat source in a high-temperature environment.

[0038] In the second step, as the second transmission shaft 25 rotates, the fifth flat gear 46 fixed thereon rotates accordingly, and the fifth flat gear 46 drives the second transmission belt 26 to operate by meshing with the second transmission belt 26, thereby rotating the fourth flat gear 27 and the third transmission shaft 28, and the rotation of the third transmission shaft 28 drives the reciprocating power supply device 44 fixed thereon to rotate. When the reciprocating power supply device 44 rotates to a predetermined position, the shift lever on the multi-link device 32 will be shifted by the shift lever on the shift lever fixing plate 45, so that the limit slider 33 in the reciprocating power supply device 44 releases the limit on the sliding conversion switch 34. At this time, the sliding conversion switch 34 falls into the reciprocating power supply device 44 due to gravity. The device 44 is located below the cross slide and is connected to the bottom circuit, causing the upper electromagnet device 31 to be powered off and the lower electromagnet device 31 to be powered on. The electromagnet device 31 with power on at the lower end adsorbs the metal-containing waste slag in the kiln tube 12, while the electromagnet device 31 with power off at the upper end loses its adsorption force, and the metal waste slag on it falls into the collecting device 16. The scraper on the collecting device 16 will scrape off the waste slag remaining on the electromagnet device 31, and the metal-containing waste slag passes through the connection between the collecting device 16 and the metal waste storage tube 18 and falls into the metal waste storage tube 18, waiting for subsequent processing, thereby realizing the resource recovery process of adsorbing and separating magnetic metals from lead and zinc smelting waste slag.

[0039] In the third step, during the rotation of the third transmission shaft 28, the first bevel gear 36 fixed thereon is engaged with the second bevel gear 38 and the third bevel gear 39, driving the three bevel gears to rotate synchronously. When the third bevel gear 39 rotates, the fourth transmission shaft 41 drives the stirring device fixing frame 42 and the spiral stirring plate 43 connected thereto to rotate, and the rotation direction of the spiral stirring plate 43 is opposite to that of the kiln barrel 12. The spiral stirring plate 43 stirs the waste slag in the kiln barrel 12 in the opposite direction, effectively preventing the waste slag from agglomerating due to high temperature, ensuring that the waste slag can be evenly heated and fully reacted. The treated waste slag finally falls into the waste slag storage barrel 17, waiting for the staff to dispose of it harmlessly.

[0040] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.

The waste residue in the kiln barrel (12) continuously climbs along the inner wall under the combined action of the friction force on the inner wall of the barrel and its own gravity, and then falls and rolls due to the action of gravity, presenting a state of spiral rolling and axial propulsion, so that the waste residue can fully contact the heat source in a high-temperature environment; S2: The second transmission shaft (25) rotates, and the fifth flat gear (46) fixed thereon rotates. The fifth flat gear (46) engages with the second transmission belt (26) to drive the second transmission belt (26) to operate, so that the fourth flat gear (27) and the third transmission shaft (28) rotate. The rotation of the third transmission shaft (28) drives the reciprocating power supply device (44) fixed thereon to rotate. The reciprocating power supply device (44) rotates to a predetermined position, and the shift lever on the multi-link device (32) is shifted by the shift lever on the shift lever fixing plate (45). The limit slider (33) in the reciprocating power supply device (44) releases the limit on the sliding conversion switch (34), and the sliding The conversion switch (34) falls under the cross slide in the reciprocating power supply device (44) due to gravity and is connected to the bottom circuit, causing the upper electromagnet device (31) to be powered off and the lower electromagnet device (31) to be powered on. The electromagnet device (31) powered on at the lower end adsorbs the metal-containing waste slag in the kiln cylinder (12). The electromagnet device (31) powered off at the upper end loses its adsorption force, and the metal waste slag on it falls into the collecting device (16). The scraper on the collecting device (16) scrapes off the waste slag remaining on the electromagnet device (31). The metal-containing waste slag passes through the connection between the collecting device (16) and the metal waste storage cylinder (18) and falls into the metal waste storage cylinder (18); S3: The third transmission shaft (28) rotates, and the first bevel gear (36) fixed thereon engages with the second bevel gear (38) and the third bevel gear (39), thereby driving the three bevel gears to rotate synchronously. When the third bevel gear (39) rotates, the fourth transmission shaft (41) drives the stirring device fixing frame (42) and the spiral stirring plate (43) connected thereto to rotate, and the rotation direction of the spiral stirring plate (43) is opposite to that of the kiln barrel (12). The spiral stirring plate (43) stirs the waste residue in the opposite direction in the kiln barrel (12). The treated waste residue finally falls into the waste residue storage barrel (17) and waits for the staff to dispose of it harmlessly.
