Description

Technical Field

[0001] This utility model relates to the field of slag recycling and reuse technology, and in particular to a zinc slag recycling device for improving the utilization rate of zinc ingots. Background Technology

[0002] In existing technologies, zinc slag recycling mostly uses traditional furnace heating and melting methods. However, such recycling equipment has many technical pain points: First, the furnace liner used to hold zinc slag is mostly a fixed structure that cannot be disassembled. After the zinc slag is melted, the remaining impurities are easy to adhere to the inner wall, making cleaning extremely difficult. Second, hard tools are often used to scrape during cleaning, which can easily damage the inner liner, thereby shortening the service life of the equipment and increasing maintenance costs.

[0003] Meanwhile, the existing equipment has a complex operating process. Adjusting the furnace tilt angle and controlling the position of cleaning components largely rely on manual operation, which is not only time-consuming and labor-intensive, but also makes it difficult to ensure the accuracy of operation and poses safety hazards. In addition, there is a lack of targeted wet cleaning methods during the cleaning process. Simply wiping or rinsing cannot effectively remove stubborn impurities remaining on the inner wall, which in turn affects the efficiency of subsequent zinc slag melting and creates a vicious cycle.

[0004] Therefore, a zinc slag recovery device to improve the utilization rate of zinc ingots is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems of cumbersome operation and poor cleaning effect, and to propose a zinc slag recovery device that is efficient, stable, easy to operate and can guarantee the cleaning effect.

[0007] Preferably, the lifting assembly includes a first right-angle sleeve fixedly mounted on one side of the upper end of the support frame, a second right-angle sleeve fixedly mounted on the other side of the upper end of the support frame and disposed opposite to the first right-angle sleeve, a rotating crossbar rotatably inserted into the second right-angle sleeve, a pair of gears welded to the outside of the rotating crossbar along its length direction and near both ends, and a bidirectional reduction motor fixedly mounted inside the first right-angle sleeve with its output end facing the rotating crossbar.

[0008] Preferably, the lifting assembly further includes a bracket that can be slidably inserted into a preset rectangular through hole at the upper end of the support frame. The bracket is a load-bearing structure for installing the cleaning assembly, and its number corresponds one-to-one with the gears.

[0009] Preferably, the output end of the bidirectional geared motor is fixedly connected to the end of the rotating crossbar away from the second right-angle sleeve, and the lower end of the bracket is integrally formed with a rack structure adapted to the gear. The teeth of the gear mesh with the slots of the rack structure of the bracket. When the bidirectional geared motor is started, it can drive the rotating crossbar to rotate around its own axis. The gear rotates synchronously with the rotating crossbar, and then drives the bracket to move up and down along the rectangular through hole through the meshing transmission of the gear and the rack.

[0010] Preferably, the cleaning assembly includes a mounting plate welded between the upper ends of two supports and arranged horizontally, a unidirectional geared motor fixedly mounted at the center of the top surface of the mounting plate with its output end pointing vertically downward, a rotating rod with one end welded to the output end of the unidirectional geared motor and the other end extending vertically downward to the top of the crucible, and a U-shaped frame soft nylon brush mounted on its outer side along the length of the rotating rod for cleaning the inner wall of the crucible, wherein the bristles of the U-shaped frame soft nylon brush can contact the inner wall of the crucible.

[0011] Preferably, the cleaning assembly further includes an annular tube fixedly mounted on the bottom surface of the mounting plate and arranged around the rotating rod, a plurality of nozzles evenly distributed along the circumference of the annular tube and embedded in the side facing the crucible, a liquid pump fixedly mounted on the edge of the top surface of the mounting plate for conveying liquid, and a three-way electric valve mounted at the water inlet of the liquid pump for switching the liquid source.

[0012] Preferably, when the unidirectional geared motor starts, it can drive the rotating rod to rotate around its own axis, thereby driving the U-shaped frame soft nylon brush to rotate synchronously to clean the inner wall of the crucible; the liquid inlet end of the annular tube is connected to the liquid outlet end of the pump through a pipe, and the nozzle is connected to the internal cavity of the annular tube; the liquid outlet end of the three-way electric valve is connected to the water inlet of the pump; that is, the annular tube, the nozzle, the pump, and the three-way electric valve form an interconnected liquid transport channel through pipes.

[0017] 4. Convenient and controllable operation. All components (furnace start / stop, motor forward / reverse rotation, liquid switching) are centrally controlled through the control box, eliminating the need for complex manual intervention. The furnace tilt angle and cleaning component lifting height can be adjusted to meet the operational needs under different working conditions and reduce the difficulty of manual operation.

[0018] 5. The structural design is reasonable and reliable. The support frame provides stable support, and the transmission structure (gear and rack, pipe connection) of each component (lifting component, cleaning component) is simple and efficient. The components are easy to install and maintain, and the whole device is compatible with the entire zinc slag recycling process, making it highly practical. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figure 1-7 As shown in the figure, this embodiment of a zinc slag recycling device for improving zinc ingot utilization includes a support frame 1. An electromagnetic furnace body 2 for melting zinc slag is rotatably mounted on the upper end of the support frame 1. A right-angle geared motor 3 for driving the electromagnetic furnace body 2 to rotate is mounted on the upper side of one side of the support frame 1. A crucible 4 for holding zinc slag is detachably mounted inside the electromagnetic furnace body 2. A lifting component 5 capable of lifting is also mounted on the upper end of the support frame 1. A cleaning component 6 for cleaning the inside of the crucible 4 is mounted on the upper end of the lifting component 5. A control box 7 is fixedly mounted on the middle of one side of the support frame 1 by a bracket. A control button 8 for operating the various components is embedded on the top surface of the control box 7. The control box 7 also integrates a controller that is electrically connected to the right-angle geared motor 3, the lifting component 5, and the cleaning component 6.

[0029] Specifically, the support frame 1 serves as the basic load-bearing structure of the entire device, providing stable installation support for the electromagnetic furnace body 2, right-angle geared motor 3, lifting assembly 5, and control box 7, ensuring that the positions of each component are fixed during operation, and avoiding the impact of device shaking on the accuracy and safety of zinc slag recycling operations.

[0030] The core melting component of the electromagnetic furnace body 2 can electromagnetically heat the zinc slag carried in the crucible 4, so that the zinc slag reaches a molten state, providing a prerequisite for the subsequent separation and recovery of zinc elements; at the same time, it can rotate on the upper end of the support frame 1, which facilitates the pouring and transfer of the molten zinc liquid.

[0031] The right-angle geared motor 3 is mounted on the upper side of the support frame 1. As a driving source, it can drive the electromagnetic furnace body 2 to rotate around the rotating shaft on the support frame 1, thereby realizing the adjustment of the tilt angle of the electromagnetic furnace body 2. This facilitates the control of the pouring speed and amount of molten zinc liquid, and meets the requirements for zinc liquid transfer.

[0032] The crucible 4 is detachably assembled inside the electromagnetic furnace body 2 and is a container that directly holds zinc dross. Its material must withstand the high-temperature heating environment of the electromagnetic furnace body 2 to avoid damage at high temperatures. The detachable design facilitates the subsequent individual cleaning, maintenance or replacement of the crucible 4, while preventing zinc dross from directly contacting the inner wall of the electromagnetic furnace body 2 and causing contamination or damage. In addition, the upper end of the crucible 4 has a double-pointed spout structure, which makes it convenient to pour the liquid or debris inside the crucible 4 from two directions.

[0033] The lifting component 5 is mounted on the upper end of the support frame 1 and is used to realize the up and down lifting action of the cleaning component 6.

[0034] The cleaning component 6 is mounted on the upper end of the lifting component 5 and is used to clean the inside of the crucible 4.

[0035] The control box 7 is fixedly mounted on the middle of one side of the support frame 1 by a bracket. It serves as the mounting carrier for the control center of the device. The internal controller is integrated, and the external control button 8 is provided with mounting positions. At the same time, the internal controller is protected from external dust, impurities and other interference, ensuring the stable operation of the control components.

[0036] The control button 8 is embedded on the top surface of the control box 7. As a human-machine interface component, the operator can send operation commands to the controller inside the control box 7 by pressing different control buttons 8, thereby controlling the start and stop of the right angle geared motor 3, the lifting component 5, and the cleaning component 6, as well as their operating status, such as the forward and reverse rotation of the bidirectional geared motor 505, the switching of the three-way electric valve 608, and the rotation of the unidirectional geared motor 602, so as to realize convenient operation of the entire zinc slag recycling device.

[0037] See appendix Figure 1-5 As shown, the lifting assembly 5 includes a first right-angle sleeve 501 fixedly mounted on one side of the upper end of the support frame 1, a second right-angle sleeve 502 fixedly mounted on the other side of the upper end of the support frame 1 and disposed opposite to the first right-angle sleeve 501, a rotating crossbar 503 rotatably inserted into the second right-angle sleeve 502, a pair of gears 504 welded to the outside of the rotating crossbar 503 along its length direction and near both ends, and a bidirectional geared motor 505 fixedly mounted inside the first right-angle sleeve 501 with its output end facing the rotating crossbar 503.

[0038] The lifting assembly 5 also includes a bracket 506 that can be slidably inserted into a pre-set rectangular through hole at the upper end of the support frame 1. The bracket 506 is a load-bearing structure for installing the cleaning assembly 6, and its number corresponds one-to-one with the gears 504.

[0039] The output end of the bidirectional geared motor 505 is fixedly connected to the end of the rotating crossbar 503 away from the second right-angle sleeve 502. The lower end of the bracket 506 is integrally formed with a rack structure that matches the gear 504. The teeth of the gear 504 mesh with the slots of the rack structure of the bracket 506. When the bidirectional geared motor 505 is started, it can drive the rotating crossbar 503 to rotate around its own axis. The gear 504 rotates synchronously with the rotating crossbar 503, and then drives the bracket 506 to move up and down along the rectangular through hole through the meshing transmission of the gear and the rack.

[0040] Specifically, the No. 1 right-angle sleeve 501 is fixed on one side of the upper end of the support frame 1, providing a stable mounting structure for the bidirectional geared motor 505, ensuring that the bidirectional geared motor 505 will not shift when it is working, and ensuring stable power output.

[0041] The second right-angle sleeve 502 is fixed on the other side of the upper end of the support frame 1 and is opposite to the first right-angle sleeve 501. It is used to provide rotational support for the rotating crossbar 503, so that the rotating crossbar 503 can rotate stably around its own axis and avoid deviation or swaying during rotation.

[0042] The rotating crossbar 503 can be rotatably inserted into the second right-angle sleeve 502. One end is fixedly connected to the output end of the bidirectional geared motor 505. As a power transmission component, it can transmit the rotational power of the bidirectional geared motor 505 to the gear 504, and at the same time provide a mounting carrier for the gear 504.

[0043] The gear 504 is welded to the outer side of the rotating crossbar 503 along its length and near both ends. It meshes with the rack structure at the lower end of the bracket 506. When the rotating crossbar 503 drives the gear 504 to rotate, the rotational motion is converted into the vertical linear motion of the bracket 506 through the meshing transmission of the gear and rack, providing power for the lifting and lowering of the bracket 506.

[0044] The bidirectional geared motor 505 is fixedly installed inside the first right-angle sleeve 501, with its output end facing the rotating crossbar 503. It is the power source of the lifting assembly 5 and can rotate forward or backward. By driving the rotating crossbar 503 to rotate forward and backward around its own axis, it controls the gear 504 to rotate forward and backward, ultimately realizing the raising or lowering of the bracket 506.

[0045] The bracket 506 can slide up and down into the pre-set rectangular through hole at the upper end of the support frame 1. The number of brackets corresponds one-to-one with the gears 504. As the bearing structure of the cleaning component 6, it is used to install and fix the mounting plate 601. It can move up and down with the meshing transmission of the gears 504 and the rack, so as to drive the cleaning component 6 closer to or away from the crucible 4 to meet the position requirements of the cleaning operation.

[0046] See appendix Figure 1-7 As shown, the cleaning assembly 6 includes a horizontally arranged mounting plate 601 welded between the upper ends of two supports 506, a unidirectional geared motor 602 fixedly mounted at the center of the top surface of the mounting plate 601 with its output end pointing vertically downward, a rotating rod 603 with one end welded to the output end of the unidirectional geared motor 602 and the other end extending vertically downward to the top of the crucible 4, and a U-shaped soft nylon brush 604 mounted on its outer side along the length of the rotating rod 603 for cleaning the inner wall of the crucible 4. The bristles of the U-shaped soft nylon brush 604 can contact the inner wall of the crucible 4.

[0047] The cleaning assembly 6 also includes an annular tube 605 fixedly mounted on the bottom surface of the mounting plate 601 and arranged around the rotating rod 603, a plurality of nozzles 606 evenly distributed along the circumference of the annular tube 605 and embedded in it on the side facing the crucible 4, a liquid pump 607 fixedly mounted on the edge of the top surface of the mounting plate 601 for conveying liquid, and a three-way electric valve 608 mounted at the water inlet of the liquid pump 607 for switching the liquid source.

[0048] When the unidirectional geared motor 602 starts, it can drive the rotating rod 603 to rotate around its own axis, thereby driving the U-shaped frame soft nylon brush 604 to rotate synchronously to clean the inner wall of the crucible 4; the liquid inlet end of the annular tube 605 is connected to the liquid outlet end of the liquid pump 607 through a pipe, and the nozzle 606 is connected to the internal cavity of the annular tube 605; the liquid outlet end of the three-way electric valve 608 is connected to the water inlet of the liquid pump 607; that is, the annular tube 605, the nozzle 606, the liquid pump 607 and the three-way electric valve 608 form an interconnected liquid transport channel through the pipe.

[0049] Specifically, the mounting plate 601 is welded between the upper ends of the two brackets 506 and is set horizontally. As the core mounting carrier of the cleaning component 6, it provides a stable mounting surface for the unidirectional geared motor 602, the annular pipe 605, and the liquid pump 607, ensuring that the positions of each cleaning component are relatively fixed and work together to complete the cleaning work.

[0050] The unidirectional geared motor 602 is fixedly mounted at the center of the top surface of the mounting plate 601, with its output end pointing vertically downward. As a rotational power source, it can drive the rotating rod 603 to rotate around its own axis when started, providing power for the rotational cleaning of the U-shaped frame soft nylon brush 604.

[0051] One end of the rotating rod 603 is welded and fixed to the output end of the unidirectional geared motor 602, and the other end extends vertically downward to the top of the crucible 4. As a power transmission and component connection structure, it can transmit the rotational power of the unidirectional geared motor 602 to the U-shaped frame soft nylon brush 604, and at the same time provide installation support for the U-shaped frame soft nylon brush 604.

[0052] The U-shaped frame soft nylon brush 604 is mounted on the outside of the rotating rod 603 along its length. The brush bristles can contact the inner wall of the crucible 4. When the rotating rod 603 drives it to rotate, the brush bristles can wipe and clean the residual zinc dross, impurities and other substances attached to the inner wall of the crucible 4, so as to avoid the residual substances affecting the subsequent zinc dross melting efficiency or contaminating the molten zinc liquid. The soft nylon material can also prevent scratching the inner wall of the crucible 4.

[0053] The annular tube 605 is fixedly mounted on the bottom surface of the mounting plate 601 and is arranged around the rotating rod 603. As a liquid conveying and distribution structure, its inlet end is connected to the outlet end of the pump 607 through a pipe. It can evenly distribute the liquid conveyed by the pump 607 to each nozzle 606 to ensure that the liquid spraying range covers the inner wall of the crucible 4.

[0054] The nozzles 606 are evenly distributed along the circumference of the annular tube 605 and embedded on the side facing the crucible 4, communicating with the internal cavity of the annular tube 605. They can spray the liquid in the annular tube 605 onto the inner wall of the crucible 4 in the form of a spray or a column, and work with the U-shaped frame soft nylon brush 604 to achieve wet cleaning and enhance the cleaning effect. At the same time, different liquids (neutral slag remover solution, neutral detergent solution or distilled water) can be sprayed as needed.

[0055] The liquid pump 607 is fixedly mounted on the top edge of the mounting plate 601. As a power source for liquid transportation, it draws liquid from the three-way electric valve 608 through its inlet port, and then pressurizes the liquid through the outlet end and delivers it to the annular pipe 605, providing power for the flow of liquid in the entire transportation channel and ensuring normal liquid discharge from the nozzle 606.

[0056] The three-way electric valve 608 is installed at the water inlet of the liquid pump 607, and the liquid outlet is connected to the water inlet of the liquid pump 607. It can switch the liquid source according to the cleaning needs (such as connecting to a neutral slag remover solution tank, a neutral detergent solution tank, or a distilled water tank) to achieve rapid switching of different types of liquids and meet the needs of different cleaning scenarios of the inner wall of the crucible 4.

[0057] The right-angle geared motor (3), the bidirectional geared motor (505), and the unidirectional geared motor (602) are self-locking motors.

[0058] The operating steps of this utility model are as follows: During the preparation and feeding of zinc slag melting, a command is sent through the control button 8 on the top surface of the control box 7, and the controller controls the electromagnetic furnace body 2 to start preheating. After the electromagnetic furnace body 2 reaches the preset melting temperature, the operator pours the zinc slag to be recycled into the crucible 4, which is detachably assembled inside the electromagnetic furnace body 2, thus completing the feeding operation.

[0059] During the zinc slag melting process, the controller is sent a command again via control button 8 to keep the electromagnetic furnace body 2 running continuously. The zinc slag in the crucible 4 is heated using the electromagnetic heating principle until the zinc slag is completely melted to form liquid zinc. During this process, the staff needs to observe the melting state of the zinc slag to ensure that the melting is complete.

[0060] When the molten zinc liquid is poured and transferred, after the zinc slag has completely melted, the right-angle geared motor 3 is started by controlling button 8. The right-angle geared motor 3 drives the electromagnetic furnace body 2 to rotate around the rotating shaft on the support frame 1, so that the electromagnetic furnace body 2 drives the crucible 4 to tilt in the preset zinc liquid collection direction (using one of the tips in the double-pointed structure of the crucible 4). The running speed of the right-angle geared motor 3 is controlled to adjust the tilt angle of the crucible 4, so that the molten zinc liquid in the crucible 4 is slowly and steadily poured from the corresponding tip into the external zinc liquid collection container until the molten zinc liquid is completely poured out. After the pouring is completed, the right-angle geared motor 3 is reversed by controlling button 8, so that the electromagnetic furnace body 2 drives the crucible 4 to return to the horizontal state.

[0061] When crucible 4 is cooling and settling, keep crucible 4 in a horizontally stable state inside the electromagnetic furnace body 2, turn off the heating function of the electromagnetic furnace body 2, and let crucible 4 cool naturally to room temperature.

[0062] When adjusting the position of cleaning component 6, after the crucible 4 has cooled to room temperature, a command is sent to the controller via the control button 8 on the control box 7 to start the bidirectional geared motor 505 in the lifting component 5 and control its forward rotation. The bidirectional geared motor 505 drives the rotating crossbar 503 to rotate around its own axis. The rotating crossbar 503 drives the gear 504 welded on the outside to rotate synchronously. The gear 504, through meshing with the rack structure at the lower end of the bracket 506, drives the bracket 506 to move downward along the pre-set rectangular through hole at the upper end of the support frame 1. The bracket 506 drives the cleaning component 6 mounted at the upper end to descend synchronously until the U-shaped frame soft nylon brush 604 in the cleaning component 6 extends into the crucible 4 and the bristles contact the inner wall of the crucible 4. At this point, the bidirectional geared motor 505 stops running, completing the positioning of the cleaning component 6.

[0063] During wet cleaning of the inner wall of crucible 4, the three-way electric valve 608 is switched to the corresponding liquid source according to the amount of residual impurities on the inner wall of crucible 4 (e.g., switching to the neutral slag remover solution tank when there is a lot of residual zinc slag, switching to the neutral detergent solution tank when there is a lot of oil). Then, the liquid pump 607 is started, and the liquid pump 607 draws the corresponding liquid through the three-way electric valve 608 and transports it through the pipeline to the annular pipe 605. The annular pipe 605 evenly distributes the liquid to each [unclear - possibly a specific location or component]. A nozzle 606 sprays liquid onto the inner wall of the crucible 4. Simultaneously, a one-way reduction motor 602 in the cleaning assembly 6 is activated. The one-way reduction motor 602 drives a rotating rod 603 to rotate around its own axis. The rotating rod 603 drives a U-shaped soft nylon brush 604 to rotate synchronously. The rotating U-shaped soft nylon brush 604, in conjunction with the liquid sprayed by the nozzle 606, wipes and cleans the zinc slag, impurities, and other residues on the inner wall of the crucible 4. The cleaning time is set according to the cleanliness of the inner wall.

[0064] When emptying the wastewater after cleaning, after cleaning is completed, turn off the liquid pump 607 and the one-way geared motor 602, and control the two-way geared motor 505 to reverse through the control button 8, so as to drive the bracket 506 and the cleaning component 6 to rise until the U-shaped frame soft nylon brush 604 is completely detached from the inside of the crucible 4, and then stop the two-way geared motor 505; then start the right angle geared motor 3, drive the electromagnetic furnace body 2 to tilt the crucible 4 in the preset wastewater collection direction (using the other tip in the double tip structure of the crucible 4), so that the wastewater generated during cleaning in the crucible 4 is poured from the corresponding tip into the external wastewater collection container until the wastewater is completely poured out.

[0065] When the cleaning components are reset and the device is shut down, after the wastewater is poured out, control the right-angle reduction motor 3 to reverse so that the electromagnetic furnace body 2 and crucible 4 are reset to a horizontal state; control the bidirectional reduction motor 505 to rotate forward or reverse through the control button 8 to adjust the support 506 and cleaning components 6 to the initial standby position (away from the area above the crucible 4); finally, turn off the power of the controller inside the control box 7 to complete the entire zinc slag recovery and crucible cleaning operation process.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
