Description

Technical Field

[0001] This invention belongs to the field of antimony alloy smelting, specifically a method and apparatus for removing cadmium in antimony alloy smelting. Background Technology

[0002] Antimony alloys are alloys composed of antimony as the base and other elements. Antimony alloys with tin, lead, and copper have high strength and are extremely wear-resistant, making them good materials for manufacturing bearings and gears. High-purity antimony and its composites with other metals (such as silver-antimony and gallium-antimony) are ideal materials for producing semiconductors and electrothermal devices.

[0003] To improve the quality of antimony alloys, it is necessary to remove impurities from the antimony raw materials. Among the more difficult impurities to remove are cadmium and arsenic. These impurities need to be removed to ensure the quality of the antimony alloy. In the existing technology, there are already relatively mature impurity removal solvents. During the preparation process, the corresponding impurity removal agent can be poured into them.

[0004] Typical impurity removal equipment has a relatively simple structure, simply having a feed inlet and a heating chamber. This can easily lead to a large amount of raw material being dumped at the feed inlet after the raw material is added, requiring no manual processing to spread the raw material evenly in the heating chamber. In addition, the entire equipment needs to be fully turned on each time the solution is observed for careful observation.

[0005] Therefore, the present invention provides a method and apparatus for removing cadmium in antimony alloy smelting. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An antimony alloy smelting cadmium removal device of this invention includes a furnace body, the interior of which is hollow, the front end of which is open, and an isolation door is slidably connected to the front end of the furnace body. A hydraulic lifting module is connected between the top of the isolation door and the furnace body. A finished product pipe communicating with the interior of the furnace body is fixedly connected to the outside of the furnace body, and a slag discharge trough communicating with the interior of the furnace body is opened on the outside of the furnace body. A slag discharge plate is slidably connected to the inner side of the slag discharge trough. Flame generators are fixedly connected to both sides of the furnace body, with the output end of the flame generator located inside the furnace body. Exhaust pipes communicating with the interior of the furnace body are also fixedly connected to both sides of the furnace body. A stirring rod is provided inside the furnace body. The top of the stirring rod is equipped with a swinging component, which drives the stirring rod to swing. This design not only improves the cadmium removal rate but also reduces manual intervention. The raw materials are simply placed into the furnace, and the stirring rod mixes and levels the materials. Subsequently, under the heating of the flame generator, the cadmium removal agent reacts with the antimony alloy, displacing the cadmium. The two products will separate into layers after melting. The upper slag layer is slowly discharged by sliding the slag plate downwards, allowing the top of the slag outlet to slowly connect to the inside of the furnace. After the slag has flowed out, the antimony alloy is removed through the finished product pipe, thus realizing the preparation of antimony alloy cadmium removal. The waste gas from the production process is discharged through the exhaust pipe, and the top of the exhaust pipe needs to be connected to a recycling and treatment device.

[0008] Preferably, the end of the inner bottom surface of the furnace body near the isolation door is higher than the end away from the isolation door. The finished product pipe is connected to the lowest point of the inner bottom surface of the furnace body. An inclined guide plate is fixed to the outer side of the furnace body. The guide plate is fixed to the outer side of the slag discharge plate near the bottom. A curved pull rod is fixed to the outer side of the slag discharge plate. By setting the bottom of the furnace body to be inclined, the raw material entering from the isolation door can be more easily spread in the furnace body under the stirring of the stirring rod and the tilting effect of gravity, which further improves the uniformity of the heating process. In addition, with this setting, when collecting the finished product at the end, the finished product pipe at the bottom can guide all the finished product out, reducing residue, while the guide plate is used to receive the outflowing slag.

[0009] Preferably, the swing assembly includes a wrapping frame, with a second drive motor fixedly connected to the inner side of the wrapping frame. The output end of the second drive motor is fixedly connected to the top of the stirring rod. A third drive motor is provided on the outer side of the wrapping frame, with its output end fixedly connected to the outer side of the wrapping frame. A spring telescopic rod is connected to the bottom of the stirring rod, with a smooth, rounded bottom. The second drive motor can drive the stirring rod to swing on one surface, while the third drive motor can drive the entire wrapping frame and the stirring rod to change angles in a vertical plane. This configuration divides the swinging motion of the stirring rod into two parts: first, the third drive motor rotates the wrapping frame, causing the bottom of the stirring rod to face the bottom of the isolation door; then, the third drive motor... Motor 2 drives the stirring rod to swing rapidly, thereby vibrating and smoothing the raw materials being connected at the door. Then, Motor 3 changes the plane of the stirring rod, causing it to swing rapidly again. This design ensures that the stirring rod contacts all the space inside the furnace. Moreover, by moving from one end of the isolation door to the other end of the finished product tube, it effectively moves the raw materials piled up at the isolation door to the end of the finished product tube, reducing the problem of raw materials accumulating at the door. The spring telescopic rod ensures that its bottom always touches the bottom of the furnace and adapts to different furnace bottom heights. In the final heating stage, the stirring rod can be rotated to a horizontal position, preventing the heating flame from directly affecting the stirring rod.

[0010] Preferably, two electric telescopic rods are fixedly connected to the outer side of the furnace body away from the isolation door. A solenoid valve is fixedly connected to the output end of each electric telescopic rod. A mating frame adapted to the solenoid valve is fixedly connected to the outer side of each spring telescopic rod. A connecting assembly is provided between the spring telescopic rod and the stirring rod. This connecting assembly connects the spring telescopic rod and the stirring rod. When replacing or not using the electric telescopic rods, after the stirring rod rotates to a horizontal position, the two electric telescopic rods are extended, allowing the solenoid valve at the end of each electric telescopic rod to contact the mating frame of the spring telescopic rod. Closing the solenoid valve at this time will lock the mating frame. As the electric telescopic rods retract, the spring telescopic rod can be pulled out. When pairing is required, as the electric telescopic rods push the spring telescopic rod against the stirring rod, the connecting assembly connects the spring telescopic rod and the stirring rod. Simultaneously, the solenoid valve is released, allowing the electric telescopic rods to disengage. This arrangement facilitates the process of connecting and releasing the spring telescopic rods.

[0011] Preferably, a material collection cylinder is fixedly connected to the bottom of the stirring rod, and the bottom of the material collection cylinder is open. An electric telescopic rod II is fixedly connected to the inner side of the stirring rod, and an extension rod is fixedly connected to the output end of the electric telescopic rod II. A quartz base is fixedly connected to the bottom of the extension rod. An observation port, flush with the electric telescopic rod I, is opened on the outer side of the furnace body. A flip plate is rotatably connected to the outer side of the observation port. When it is necessary to observe the solution condition using the material collection cylinder, the electric telescopic rod II is activated, causing the extension rod to extend the quartz base. The quartz base is not only transparent but also heat-resistant. The stirring rod is rotated to a vertical position, at which point the spring telescopic rod is in the extended position. At this time, part of the material collection cylinder is in the solution, allowing the solution to enter the vertically positioned material collection cylinder. Then, the electric telescopic rod II moves the quartz upwards to the closed collection position. The system uses a cylindrical container to isolate part of the solution within the sampling cylinder. Because the sampling cylinder is in a vertical position when sampling, it can collect portions of both the upper and lower layers of solution. Then, as the stirring rod rotates back to a horizontal position, the driving motor rotates both the stirring rod and the sampling cylinder to one side, positioning the sampling cylinder at the observation port. By opening the flip plate, the stratification of the solution can be observed through the bottom of the quartz base. The top surface of the sampling cylinder, once horizontal, can be rotated open to observe whether there are any clumps inside the sampled solution. This design allows for observation of the solution's state without opening the isolation door, reducing the problem of large-scale heat leakage and providing closer observation of the solution's condition, effectively improving control over the solution's state. After observation, the solution can be returned to its original position.

[0012] Preferably, the outer side of the furnace body is provided with an inclined sliding groove, in which an isolation plate is slidably connected. A power assembly is fixedly connected to the outer side of the furnace body. The power assembly is used to drive the isolation plate to slide. In order to reduce the impact of heat in the furnace on the electrical appliances above, the isolation plate is set so that during the processing, the power assembly drives the isolation plate to slide up, separating the upper and lower furnace bodies and reducing the impact of heat on the electrical appliances above. At the same time, the isolation plate can reflect heat more directly, ensuring high temperature inside the furnace. When the isolation plate needs to be opened when the material is being taken out of the feeding cylinder or when the raw material is being leveled, the power assembly can be turned off, and the isolation plate can be allowed to slide down and open under the action of gravity.

[0013] Preferably, the docking assembly includes two symmetrically arranged forked rods, each forked rod being cylindrical and made of elastic metal. A splitting groove of the same length as the forked rod is formed in the middle of each forked rod. Two docking rings adapted to the forked rods are fixed to the outer side of the material receiving cylinder. Two separating blocks for spreading the forked rods are also fixed to the outer side of the material receiving cylinder. When assembling the spring telescopic rod, simply push the spring telescopic rod forward using the electric telescopic rod. The forked rod will pass through the docking ring. After passing through, the splitting groove in the middle of the forked rod will insert into the separating block, causing the forked rod to split. This allows the forked rod to be fixed to the docking ring, and the greater the compression, the greater the bonding force. At this point, closing the solenoid valve and retracting the electric telescopic rod will fix the spring telescopic rod to the material receiving cylinder. When it needs to be pulled out, simply pull the spring telescopic rod outwards. Furthermore, when passing through the docking ring, the forked rod can be brought together towards the center for future use.

[0014] Preferably, a separation frame is slidably connected to the top of the furnace body, and a hydraulic telescopic rod is fixedly connected to the top of the furnace body. The bottom output end of the hydraulic telescopic rod is fixedly connected to the separation frame. Support rods are fixedly connected to the outer sides of the enclosure frame and the drive motor. One support rod is fixedly connected to the separation frame, and a locking disc is fixedly connected to the end of the other support rod. A locking seat is fixedly connected to the inner side of the separation frame, and multiple elastic protrusions are fixedly connected to the outer side of the locking disc. The surface of the locking seat has a limiting groove that matches the locking disc. To ensure that all the solution on the vertical plane can be retrieved, when... After the quartz base is pushed outwards and the material collection cylinder is vertical, the hydraulic telescopic rod drives the entire separation frame to sink, thereby causing the stirring rod to sink. At this time, the electric telescopic rod 2 slowly lifts the quartz base in coordination with the sinking speed, finally bringing the bottom of the material collection cylinder into contact with the bottom of the furnace body and sealing the material collection cylinder. This downward-pressing sealing material collection method allows the material collection cylinder to be sealed and extracted to the vertical surface, ensuring that the actual state of the liquid in the furnace can be accurately simulated during observation, thus improving the accuracy of observation. The cooperation between the locking seat and the locking plate allows the wrapping frame to be maintained relatively stably in a plane.

[0015] Preferably, the power assembly includes two winding discs, the interior of which is hollow. A drive motor is fixedly connected to the outer side of the winding disc, and the output end of the drive motor is located inside the winding disc. A pull rope is fixedly connected between the outer side of the isolation plate and the output end of the drive motor. By rotating the drive motor, the pull rope can be wound or released, thereby pulling the isolation plate upward or causing the isolation plate to move downward.

[0016] A method for removing cadmium in antimony alloy smelting, applicable to the aforementioned antimony alloy smelting cadmium removal apparatus, the method specifically comprising:

[0017] S1: Open the isolation door, send the antimony alloy raw material into the furnace body, and add sufficient cadmium removal agent into the furnace body at the same time. At the same time, close the isolation door. Drive motor 2 can drive the stirring rod to swing on one surface, while drive motor 3 can drive the entire wrapping frame and stirring rod to change the angle in the vertical plane.

[0018] S2: First, drive motor three to rotate the package frame so that the bottom of the stirring rod faces the bottom of the isolation door. Drive motor two drives the stirring rod to swing quickly to vibrate and smooth the raw material connected at the door. Then, drive motor three changes the plane of the stirring rod and then makes the stirring rod swing quickly to smooth the raw material in the furnace and spread it evenly on the bottom of the furnace.

[0019] S3: After the reaction has been going on for a period of time, the stirring rod is rotated and inserted vertically into the solution. The hydraulic telescopic rod drives the entire separation frame to sink, which in turn causes the stirring rod to sink. At this time, the electric telescopic rod 2 slowly lifts the quartz base in coordination with the sinking speed, and finally the bottom of the material taking tube is attached to the bottom of the furnace body and the material taking tube is sealed. Finally, the material taking tube is extended out of the furnace body and penetrates the internal solution to determine the reaction status inside the furnace.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The present invention discloses a method and apparatus for removing cadmium from antimony alloy smelting. By setting up a stirring rod, the cadmium removal rate is improved, and the manual intervention steps are reduced. The raw materials are simply placed into the furnace body, and the stirring rod can mix and level the materials. Subsequently, under the heating of the flame generator, the cadmium removal agent reacts with the antimony alloy, displacing the cadmium. The two products will separate into layers after melting. The upper layer of slag is allowed to slowly flow out by sliding the slag plate downwards, allowing the top of the slag outlet to slowly connect to the inside of the furnace. After the slag has flowed out, the antimony alloy is taken out through the finished product pipe, thus realizing the preparation of antimony alloy with cadmium removal. The waste gas produced during production is discharged through the exhaust pipe, and the top of the exhaust pipe needs to be connected to a recycling and treatment device.

[0022] 2. The method and apparatus for removing cadmium in antimony alloy smelting according to the present invention, by setting the bottom of the furnace body to be inclined, the raw material entering from the isolation door can be more easily spread in the furnace body under the stirring of the stirring rod and the tilting action of gravity, which further improves the uniformity of the heating process. In addition, with this setting, when collecting the finished product at the end, the finished product pipe at the bottom can guide all the finished product out, reducing residue, while the guide plate is used to receive the outflowing slag.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figures 1 to 3 As shown in the embodiment of the present invention, an antimony alloy smelting cadmium removal device includes a furnace body 1. The interior of the furnace body 1 is hollow. The front end of the furnace body 1 is open and a sliding isolation door 2 is slidably connected to the front end of the furnace body 1. A hydraulic lifting module is connected between the top of the isolation door 2 and the furnace body 1. A finished product pipe 13 communicating with the interior of the furnace body 1 is fixedly connected to the outside of the furnace body 1. A slag discharge trough communicating with the interior of the furnace body 1 is opened on the outside of the furnace body 1. A slag discharge plate 7 is slidably connected to the inside of the slag discharge trough. Flame generators 8 are fixedly connected to both sides of the furnace body 1. The output end of the flame generator 8 is located inside the furnace body 1. Exhaust pipes 5 communicating with the interior of the furnace body 1 are also fixedly connected to both sides of the furnace body 1. A stirring rod 12 is provided inside the furnace body 1. A swing assembly is provided at the top of the stirring rod 12. The swing assembly is used to drive the stirring rod 12 to swing.

[0035] During operation, the isolation door 2 is opened, and the antimony alloy raw material is fed into the furnace body 1. Simultaneously, a sufficient amount of cadmium removal agent is added inside the furnace body 1. The oscillating assembly is activated, causing the bottom of the stirring rod 12 to contact the bottom surface of the furnace body 1. The oscillating assembly also causes the stirring rod 12 to oscillate, thus shaking the antimony alloy raw material and the cadmium removal agent. This disperses and evenly distributes the raw material at the entrance of the isolation door 2. The stirring of the stirring rod 12 ensures that the raw material is spread as evenly as possible on the surface of the furnace body 1, allowing for more uniform heating. Furthermore, the antimony alloy raw material and the cadmium removal agent blend together, resulting in better removal of cadmium from the antimony alloy. This setup not only... The process improves the cadmium removal rate and reduces manual intervention steps. The raw materials are simply placed into the furnace body 1, and the stirring rod 12 mixes and levels the materials. Subsequently, under the heating of the flame generator 8, the cadmium removal agent reacts with the antimony alloy, displacing the cadmium. The two products will separate into layers after melting. The upper slag layer is slowly connected to the furnace interior by sliding the slag plate 7 downwards, allowing the upper molten slag to flow out slowly. After the molten slag has flowed out, the antimony alloy is removed through the finished product pipe 13, thus realizing the preparation of antimony alloy cadmium removal. The waste gas produced during production is discharged through the exhaust pipe 5, and the top of the exhaust pipe 5 needs to be connected to a recycling and treatment device.

[0036] like Figures 1 to 3 As shown, the end of the inner bottom surface of the furnace body 1 closest to the isolation door 2 is higher than the end furthest from the isolation door 2. The finished product pipe 13 is connected to the lowest point of the inner bottom surface of the furnace body 1. An inclined guide plate 6 is fixed to the outer side of the furnace body 1. The guide plate 6 is fixed to the outer side of the slag discharge plate 7 near the bottom. A curved pull rod is fixed to the outer side of the slag discharge plate 7. During operation, by setting the bottom of the furnace body 1 to be inclined, the raw material entering from the isolation door 2 can be more easily spread in the furnace body 1 under the stirring of the stirring rod 12 and the tilting effect of gravity, which further improves the uniformity of the heating process. In addition, with this setting, when collecting the finished product at the end, the finished product pipe 13 at the bottom can guide all the finished product out, reducing residue, while the guide plate 6 is used to receive the outflowing slag.

[0037] like Figures 2 to 4 As shown, the rocking assembly includes a wrapping frame 11, a second drive motor 26 is fixedly connected to the inner side of the wrapping frame 11, the output end of the second drive motor 26 is fixedly connected to the top end of the stirring rod 12, a third drive motor 27 is provided on the outer side of the wrapping frame 11, the output end of the third drive motor 27 is fixedly connected to the outer side of the wrapping frame 11, and a spring telescopic rod 14 is connected to the bottom of the stirring rod 12, the bottom of the spring telescopic rod 14 is smoothly rounded.

[0038] During operation, drive motor 26 drives the stirring rod 12 to oscillate on one surface, while drive motor 3 drives the entire packaging frame 11 and the stirring rod 12 to change angles in the vertical plane. This configuration divides the oscillation motion of the stirring rod 12 into two parts. First, drive motor 3 drives the packaging frame 11 to rotate, so that the bottom of the stirring rod 12 faces the bottom of the isolation door 2. Drive motor 26 then drives the stirring rod 12 to oscillate rapidly, thereby vibrating and smoothing the raw materials being connected at the doorway. Then, drive motor 3 changes the plane in which the stirring rod 12 is located, and then the stirring rod 12... The rapid oscillation allows the stirring rod 12 to contact all the space inside the furnace body 1. Moreover, by moving from one end of the isolation door 2 to one end of the finished product tube 13, the raw materials piled up at the isolation door 2 can be effectively moved to one end of the finished product tube 13, reducing the problem of raw materials accumulating at the doorway. The spring telescopic rod 14 is designed so that its bottom can always touch the bottom of the furnace body 1 and adapt to different furnace bottom heights. At the same time, in the final heating stage, the stirring rod 12 can be rotated to a horizontal state so that the heating flame does not directly act on the stirring rod 12.

[0039] like Figures 3 to 5 As shown, two electric telescopic rods 15 are fixedly connected to the outer side of the furnace body 1 away from the isolation door 2. The output end of the electric telescopic rod 15 is fixedly connected to a solenoid valve. The outer side of the spring telescopic rod 14 is fixedly connected to a docking frame adapted to the solenoid valve. A connecting component is provided between the spring telescopic rod 14 and the stirring rod 12. The connecting component is used to connect the spring telescopic rod 14 and the stirring rod 12.

[0040] When replacing or not using the electric telescopic rod 15 during operation, after the agitator rod 12 rotates to a horizontal position, both electric telescopic rods 15 are extended, allowing the solenoid valves at the ends of the electric telescopic rods 15 to contact the docking frame of the spring telescopic rod 14. Closing the solenoid valves at this time will lock the docking frame. As the electric telescopic rod 15 retracts, the spring telescopic rod 14 can be pulled out. When pairing is required, the electric telescopic rod 15 pushes the spring telescopic rod 14 and the agitator rod 12 in the same direction. Through the connection of the connecting components, the spring telescopic rod 14 and the agitator rod 12 can be connected. At the same time, the solenoid valves are released, allowing the electric telescopic rod 15 to disengage. This design facilitates the docking and undoing of the spring telescopic rod 14.

[0041] like Figures 3 to 5As shown, a material taking cylinder 21 is fixedly connected to the bottom of the stirring rod 12. The bottom of the material taking cylinder 21 is open. An electric telescopic rod 23 is fixedly connected to the inner side of the stirring rod 12. An extension rod 22 is fixedly connected to the output end of the electric telescopic rod 23. A quartz base 24 is fixedly connected to the bottom of the extension rod 22. An observation port 17, which is flush with the electric telescopic rod 15, is opened on the outer side of the furnace body 1. A flip plate 33 is rotatably connected to the outer side of the observation port 17.

[0042] During operation, in the process of heating cadmium, in addition to judging the heating status by time, the most direct method is to observe whether the metal solution shows obvious stratification and whether there are still unmelted clumps in the solution to determine whether the reaction has been completed. A completely stable stratified solution should have a red upper layer and a silvery-white lower layer. If the reaction is judged solely by time, the reaction time will be difficult to control due to the difference in the amount of raw materials each time. Traditional observation methods can only be used by opening the isolation door 2, inserting a metal rod inside, and skimming off the upper layer to observe the specific situation of the solution. This method is too cumbersome and has certain dangers.

[0043] By using the feeding tube 21, when it is necessary to observe the solution, the electric telescopic rod 23 is activated, causing the extension rod 22 to extend the quartz base 24. The quartz base 24 is not only transparent but also heat-resistant. The stirring rod 12 is rotated to a vertical position, at which point the spring telescopic rod 14 is in the extended position. At this time, part of the feeding tube 21 is in the solution, allowing the solution to enter the vertically positioned feeding tube 21. Then, the electric telescopic rod 23 moves the quartz upwards to the closed feeding tube 21, thus isolating part of the solution in the feeding tube 21. Since the feeding tube 21 is in a vertical position when feeding, a portion of the upper and lower layers of solution can be taken. Then, with the stirring rod 12... Rotate again to horizontal, and simultaneously rotate the stirring rod 12 and the feeding cylinder 21 to one side via the drive motor 26, so that the feeding cylinder 21 is rotated to the position of the observation port 17. By opening the flip plate 33, the layering phenomenon of the solution can be observed through the bottom of the quartz base 24. At the same time, the top surface of the feeding cylinder 21 after being horizontal can be rotated open to observe whether there are lumps inside the taken solution. With this setting, the solution state can be observed without opening the isolation door 2, reducing the problem of large-scale leakage of internal heat. At the same time, the solution condition can be observed more closely, effectively improving the control of the solution state. After the observation is completed, the solution can be returned to its original path.

[0044] like Figures 1 to 3As shown, an inclined sliding groove 16 is provided on the outer side of the furnace body 1. An isolation plate 10 is slidably connected in the sliding groove 16. A power assembly is fixed to the outer side of the furnace body 1. The power assembly is used to drive the isolation plate 10 to slide. During operation, in order to reduce the impact of heat in the furnace on the electrical appliances above, the isolation plate 10 is set up so that the upper and lower furnace bodies 1 are separated by the power assembly during processing, reducing the impact of heat on the electrical appliances above. At the same time, the isolation plate 10 can reflect heat more directly to ensure high temperature in the furnace. When the material taking cylinder 21 takes material or smooths the raw material, and the isolation plate 10 needs to be opened, the power assembly only needs to be turned off, and the isolation plate 10 can slide down and open under the action of gravity.

[0045] like Figure 5 As shown, the docking assembly includes two symmetrically arranged forked rods 19, each forked rod 19 being cylindrical and made of elastic metal. A splitting groove of the same length as the forked rod 19 is formed in the middle of each forked rod 19. Two docking rings 20 adapted to the forked rods 19 are fixedly connected to the outer side of the material taking cylinder 21. Two separating blocks 29 for opening the forked rods 19 are also fixedly connected to the outer side of the material taking cylinder 21. During operation, when assembling the spring telescopic rod 14, it is only necessary to drive the spring telescopic rod 14 through the electric telescopic rod 15. 4. Push forward, and the forked rod 19 will pass through the docking ring 20. After passing through, the split groove in the middle of the forked rod 19 will insert into the separating block 29, causing the forked rod 19 to split, thereby fixing the forked rod 19 on the docking ring 20. The more it is squeezed, the greater the bonding force. At this time, close the solenoid valve and let the electric telescopic rod 15 retract, which will fix the spring telescopic rod 14 on the material picking cylinder 21. When it needs to be pulled out, simply pull the spring telescopic rod 14 outward. When passing through the docking ring 20, the forked rod 19 can also be brought together towards the center for the next use.

[0046] like Figures 3 to 4As shown, a separation frame 4 is slidably connected to the top of the furnace body 1, and a hydraulic telescopic rod 3 is fixedly connected to the top of the furnace body 1. The bottom output end of the hydraulic telescopic rod 3 is fixedly connected to the separation frame 4. Support rods 25 are fixedly connected to the outer sides of the wrapping frame 11 and the drive motor 27. One support rod 25 is fixedly connected to the separation frame 4, and a locking disc 31 is fixedly connected to the end of the other support rod 25. A locking seat 30 is fixedly connected to the inner side of the separation frame 4, and multiple elastic protrusions are fixedly connected to the outer side of the locking disc 31. The surface of the locking seat 30 is provided with a limiting groove that matches the locking disc 31. During operation, in order to ensure that all the melt on the vertical plane can be taken out... When the quartz base 24 is pushed outward and the material collection cylinder 21 is vertical, the hydraulic telescopic rod 3 drives the entire separation frame 4 to sink, thereby causing the stirring rod 12 to sink. At this time, the electric telescopic rod 23, in coordination with the sinking speed, slowly lifts the quartz base 24, finally bringing the bottom of the material collection cylinder 21 into contact with the bottom of the furnace body 1 and sealing the material collection cylinder 21. This downward-pressing sealing material collection method allows the material collection cylinder 21 to be sealed and extracted to the vertical surface, ensuring that the actual state of the liquid in the furnace can be accurately simulated during observation, thus improving the accuracy of observation. The cooperation between the locking seat 30 and the locking plate 31 allows the wrapping frame 11 to be maintained relatively stably in a plane.

[0047] like Figure 7 As shown, a method for removing cadmium in antimony alloy smelting is provided. This method is applicable to the aforementioned antimony alloy smelting cadmium removal device. The method specifically comprises:

[0048] S1: Open the isolation door 2, send the antimony alloy raw material into the furnace body 1, and at the same time add sufficient cadmium removal agent into the furnace body 1. At the same time, close the isolation door 2. The second drive motor 26 can drive the stirring rod 12 to swing on one surface, while the third drive motor 27 can drive the entire wrapping frame 11 and the stirring rod 12 to change the angle in the vertical plane.

[0049] S2: First, drive motor 3 27 to rotate the packaging frame 11 so that the bottom of the stirring rod 12 faces the bottom of the isolation door 2. Drive motor 2 26 drives the stirring rod 12 to swing rapidly to vibrate and smooth the raw material connected at the door. Then, drive motor 3 27 changes the plane of the stirring rod 12 and then makes the stirring rod 12 swing rapidly to smooth the raw material in the furnace and spread it evenly on the bottom of the furnace.

[0050] S3: After a period of reaction, the stirring rod 12 is rotated and vertically inserted into the solution. The hydraulic telescopic rod 3 drives the entire separation frame 4 to sink, thereby causing the stirring rod 12 to sink. At this time, the electric telescopic rod 23, in coordination with the sinking speed, slowly lifts the quartz base 24, finally bringing the bottom of the material taking cylinder 21 into contact with the bottom of the furnace body 1 and sealing the material taking cylinder 21. Finally, the material taking cylinder 21 is extended out of the furnace body 1 and penetrates the internal solution to determine the reaction status inside the furnace.

[0051] Example 2

[0052] like Figures 1 to 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the power assembly includes two winding discs 28, the interior of the winding discs 28 is hollow, a drive motor 9 is fixedly connected to the outer side of the winding discs 28, the output end of the drive motor 9 is located on the inner side of the winding discs 28, and a pull rope 32 is fixedly connected between the outer side of the isolation plate 10 and the output end of the drive motor 9. During operation, the pull rope 32 can be wound or released by the rotation of the drive motor 9, thereby pulling the isolation plate 10 upward or causing the isolation plate 10 to move downward.

[0053] During operation, the isolation door 2 is opened, and the antimony alloy raw material is fed into the furnace body 1. Simultaneously, a sufficient amount of cadmium removal agent is added inside the furnace body 1. The oscillating assembly is activated, causing the bottom of the stirring rod 12 to contact the bottom surface of the furnace body 1. The oscillating assembly also causes the stirring rod 12 to oscillate, thus shaking the antimony alloy raw material and the cadmium removal agent. This disperses and evenly distributes the raw material at the entrance of the isolation door 2. The stirring of the stirring rod 12 ensures that the raw material is spread as evenly as possible on the surface of the furnace body 1, allowing for more uniform heating. Furthermore, the antimony alloy raw material and the cadmium removal agent blend together, resulting in better removal of cadmium from the antimony alloy. This setup not only... The process improves the cadmium removal rate and reduces manual intervention steps. The raw materials are simply placed into the furnace body 1, and the stirring rod 12 can mix and level them. Subsequently, under the heating of the flame generator 8, the cadmium removal agent can react with the antimony alloy to replace the cadmium. The two products will separate into layers after melting. The upper slag is slowly connected to the furnace interior by sliding the slag plate 7 downwards, allowing the upper molten slag to flow out slowly. After the molten slag has flowed out, the antimony alloy is taken out through the finished product pipe 13, thus realizing the preparation of antimony alloy cadmium removal. The waste gas in the production is discharged through the exhaust pipe 5, and the top of the exhaust pipe 5 needs to be connected to the recycling and treatment device.

[0054] By setting the bottom of the furnace body 1 to be inclined, the raw materials entering from the isolation door 2 can be more easily spread in the furnace body 1 under the stirring of the stirring rod 12 and the tilting effect of gravity, which further improves the uniformity of the heating process. In addition, with this setting, when collecting the finished product at the end, the finished product pipe 13 at the bottom can guide all the finished product out, reducing the residue, while the guide plate 6 is used to receive the outflowing scum.

[0055] Drive motor 26 can drive the stirring rod 12 to swing on one surface, while drive motor 27 can drive the entire packaging frame 11 and the stirring rod 12 to change angles in the vertical plane. This arrangement divides the swinging motion of the stirring rod 12 into two parts. First, drive motor 27 drives the packaging frame 11 to rotate, so that the bottom of the stirring rod 12 faces the bottom of the isolation door 2. Drive motor 26 drives the stirring rod 12 to swing rapidly, thereby vibrating and smoothing the raw materials connected at the door. Then, drive motor 27 changes the plane on which the stirring rod 12 is located, and then the stirring rod 12 swings rapidly again. The swaying mechanism allows the stirring rod 12 to contact all the spaces inside the furnace body 1. Furthermore, by moving from one end of the isolation door 2 to one end of the finished product tube 13, it effectively moves the raw materials piled up at the isolation door 2 to the end of the finished product tube 13, reducing the problem of raw material accumulation at the doorway. The spring telescopic rod 14 allows its bottom to always touch the bottom of the furnace body 1, adapting to different furnace bottom heights. Simultaneously, during the final heating stage, the stirring rod 12 can be rotated to a horizontal position, preventing the heating flame from directly affecting the stirring rod 12.

[0056] When replacing or not using the electric telescopic rod 15, after the stirring rod 12 is rotated to the horizontal position, both electric telescopic rods 15 are extended, allowing the solenoid valve at the end of the electric telescopic rod 15 to contact the docking frame of the spring telescopic rod 14. At this time, closing the solenoid valve will lock the docking frame. As the electric telescopic rod 15 retracts, the spring telescopic rod 14 can be pulled out. When pairing is required, as the electric telescopic rod 15 pushes the spring telescopic rod 14 and the stirring rod 12 in the same direction, the spring telescopic rod 14 and the stirring rod 12 can be connected through the connection component. At the same time, the solenoid valve is released to disengage the electric telescopic rod 15. This setting facilitates the docking and unfixing process of the spring telescopic rod 14.

[0057] In the process of heating cadmium, in addition to judging the heating status by time, the most direct method is to observe whether the metal solution shows obvious stratification and whether there are still unmelted clumps in the solution to determine whether the reaction has been completed. The upper layer of a completely stable stratified solution should be red and the lower layer should be silvery-white. If the reaction is judged solely by time, the reaction time will be difficult to control due to the difference in the amount of raw materials each time. The traditional observation method can only be done by opening the isolation door 2, inserting a metal rod inside, and skimming off the upper layer to observe the specific situation of the solution. This method is too cumbersome and has certain dangers.

[0058] By using the feeding tube 21, when it is necessary to observe the solution, the electric telescopic rod 23 is activated, causing the extension rod 22 to extend the quartz base 24. The quartz base 24 is not only transparent but also heat-resistant. The stirring rod 12 is rotated to a vertical position, at which point the spring telescopic rod 14 is in the extended position. At this time, part of the feeding tube 21 is in the solution, allowing the solution to enter the vertically positioned feeding tube 21. Then, the electric telescopic rod 23 moves the quartz upwards to the closed feeding tube 21, thus isolating part of the solution in the feeding tube 21. Since the feeding tube 21 is in a vertical position when feeding, a portion of the upper and lower layers of solution can be taken. Then, with the stirring rod 12... Rotate again to the horizontal position, and simultaneously rotate the stirring rod 12 and the feeding cylinder 21 to one side via the drive motor 26, so that the feeding cylinder 21 is rotated to the position of the observation port 17. By opening the flip plate 33, the layering phenomenon of the solution can be observed through the bottom of the quartz base 24. At the same time, the top surface of the feeding cylinder 21 after being horizontal can be rotated open to observe whether there are lumps inside the taken solution. With this setting, the solution state can be observed without opening the isolation door 2, reducing the problem of large-scale leakage of internal heat. At the same time, the solution state can be observed more closely, effectively improving the control of the solution state. After the observation is completed, the solution can be returned to the original path.

[0059] To reduce the impact of heat inside the furnace on the electrical appliances above, the isolation plate 10 is installed. During the processing, the power component drives the isolation plate 10 to slide upward, separating the upper and lower furnace bodies 1, reducing the impact of heat on the electrical appliances above. At the same time, the isolation plate 10 can reflect heat more directly, ensuring high temperature inside the furnace. When the material taking cylinder 21 takes material or smooths the raw material, if the isolation plate 10 needs to be opened, simply turn off the power component, and the isolation plate 10 will slide down and open under the action of gravity.

[0060] When assembling the spring telescopic rod 14, simply use the electric telescopic rod 15 to push the spring telescopic rod 14 forward. The forked rod 19 will pass through the docking ring 20. After passing through, the split groove in the middle of the forked rod 19 will insert into the separating block 29, causing the forked rod 19 to split. This allows the forked rod 19 to be fixed on the docking ring 20, and the more it is squeezed, the greater the bonding force. At this time, close the solenoid valve and let the electric telescopic rod 15 retract to fix the spring telescopic rod 14 on the feeding cylinder 21. When it needs to be pulled out, simply pull the spring telescopic rod 14 outward. When passing through the docking ring 20, the forked rod 19 can also be brought together towards the center for the next use.

[0061] To ensure that all the solution on the vertical plane can be obtained, after the quartz base 24 is pushed outward and the material collection cylinder 21 is vertical, the hydraulic telescopic rod 3 drives the entire separation frame 4 to sink, thereby causing the stirring rod 12 to sink. At this time, the electric telescopic rod 23, in coordination with the sinking speed, slowly lifts the quartz base 24, finally bringing the bottom of the material collection cylinder 21 into contact with the bottom of the furnace body 1 and sealing the material collection cylinder 21. This downward-pressing and sealing material collection method allows the material collection cylinder 21 to be sealed and extract multiple layers of raw materials on the vertical plane, ensuring that the actual state of the liquid in the furnace can be accurately simulated during observation, thus improving the accuracy of observation. The cooperation between the locking seat 30 and the locking plate 31 allows the wrapping frame 11 to be maintained relatively stably in a plane.
