Description

Technical Field

[0001] The present invention relates to the field of metallurgy, and in particular provides a tin slag processing device for tin ingot processing. Background Art

[0002] As a common metal, tin has a wide range of uses, including as a coating material in the food, machinery, electrical appliances, automotive, aerospace, and other industries. In float glass production, molten glass floats on the surface of a molten tin pool, where it cools and solidifies. Tin readily bonds with iron and is used as an anti-corrosion coating for lead, zinc, and steel.

[0003] There are generally two processing methods for tin ingots: one is to directly smelt raw materials, and the other is to process recycled tin slag. Tin slag contains a large amount of tin, which can be recycled after smelting. However, because tin easily combines with other metals to form alloys and is also easily oxidized, the tin slag contains impurities such as alloys and tin oxide. The melting point of tin is much lower than that of impurities such as alloys and tin oxide, so the tin slag is generally processed by smelting and filtering.

[0004] Existing tin slag processing devices are mostly tin slag reduction machines, which are relatively simple devices. Most of them heat the tin slag in the open air to melt it into liquid, and use gravity to separate the liquid solder from the oxide. The heating process causes serious energy loss, and the molten tin is easily oxidized by the air. The production efficiency of pure tin is very low, and the product obtained is not proportional to the input cost, making it difficult to be used on a large scale. Summary of the Invention

[0005] In order to address the technical defects of the prior art, the present invention provides a tin slag treatment device for tin ingot processing, which can effectively solve the problems in the background technology.

[0006] The present invention is achieved through the following technical solutions:

[0007] The jar is connected with the tumbler to form a slurry filter, and the tumbler has a bottom slurry filter, and the tumbler has a bottom slurry filter, and the tumbler has a bottom slurry filter. A power transmission device is used to control the sealing state of the smelting chamber, which is convenient for sealing after the tin slag is placed in the smelting chamber. At the same time, the power transmission device provides power for the stirring mechanism, which stirs continuously during the smelting process to make the tin slag solution heated more evenly, which is convenient for melting the tin in the tin slag. The tin slag processing device completes smelting and filtration in an integrated manner, reducing oxidation during the transfer of the tin slag solution, reducing raw material loss, and reducing production costs. The air pressure system can prevent the air pressure in the smelting chamber from being too high while ensuring the sealing of the smelting chamber, avoiding damage to the device. During the smelting process, the air pressure system sends excess high-temperature and high-pressure gas generated by the heating of the smelting chamber into the filter chamber, heats the filter chamber in advance, provides a suitable temperature environment for the filtration of the tin slag solution, and achieves rational use of energy.

[0008] Furthermore, the power transmission device includes a set-top box fixed at the center position of the upper end surface of the kettle body, and a transmission space is provided inside the set-top box. A transmission rod is rotatably connected to the left side of the upper end wall of the transmission space, and a central axis is rotatably provided at the lower end wall of the transmission space. The central axis vertically penetrates the center position of the upper end wall of the smelting chamber and extends into the smelting chamber. The central axis is rotatably connected to the penetration point of the upper end wall of the smelting chamber, and the lower end of the transmission rod vertically penetrates the central axis and extends into the smelting chamber. The penetration point of the transmission rod and the central axis is connected by a ratchet. The upper end surface of the set-top box A motor is fixedly installed on the right side. The motor core shaft of the motor extends downward through the upper end wall of the transmission space and is rotatably connected to the lower end wall of the transmission space. The first gear and the second gear are respectively provided on the upper and lower sides of the shaft body of the motor core shaft. The first gear and the second gear are both fixedly sleeved on the shaft body of the motor core shaft through the center position. The upper side of the rod body of the transmission rod is fixedly sleeved at the same level as the first gear. The first gear and the third gear are meshed and connected in transmission. A semi-annular rack is provided at the same level as the second gear on the outer ring surface of the central shaft. The semi-annular rack is meshed with the second gear. The motor is used to provide power, and the cooperation of the first gear, the second gear, the third gear, the semi-annular rack and the ratchet makes the transmission rod and the central shaft controlled by the motor rotate differently in different working states of forward and reverse rotation, thereby achieving a motor-controlled closed state of the feed port and stirring operation, without the need for an additional power source, reducing the cost of the device.

[0009] Advantageously, a horizontally placed strip plate is provided on the upper side of the interior of the smelting chamber, the lower end of the transmission rod is located inside the smelting chamber and fixedly connected to the center position of the upper end face of the strip plate, the left and right ends of the strip plate are both rotatably hoisted with a vertical downward rotating shaft, the shaft body of the rotating shaft is fixedly sleeved with a pentagonal dial plate, four medium-frequency electric heating plates are distributed in an annular shape inside the annular inner wall of the smelting chamber, and four vertical fixed dial plates are evenly distributed around the circumference of the annular interior of the smelting chamber, and the distance between the center line of the rotating shaft and the vertex of the fixed dial plate is less than the radius of the inscribed circle of the regular pentagon formed by the five corners of the pentagonal dial plate. During the process of the pentagonal dial plates on the left and right sides revolving around the center line of the transmission rod, the pentagonal dial plates will be toggled by one angle by the fixed dial plate and rotated, the revolution being clockwise and the rotation being counterclockwise, which can make the tin slag solution in the smelting chamber flow disordered, facilitate the spread of heat, and ensure uniform heating.

[0010] Furthermore, the transmission rod and the center line of the central shaft are on the same vertical line, the ratchet is a one-way transmission structure and the forward rotation direction is counterclockwise rotation, the semi-annular rack is arranged on the front annular surface of the central shaft, and the transmission ratio between the first gear and the third gear is the same as the transmission ratio between the second gear and the semi-annular rack. Before the tin slag is put into the smelting chamber, the motor reverses and the motor core shaft rotates clockwise. At this time, the transmission rod rotates counterclockwise, and the ratchet drives the central shaft to rotate counterclockwise, so that the feed port is opened. In the process of counterclockwise rotation of the central shaft, the right side of the semi-annular rack will contact and mesh with the second gear. The same transmission ratio can ensure that the transmission of the two gear meshing is not interfered with; after the tin slag is put into the smelting chamber, the motor rotates forward and the motor core shaft rotates counterclockwise. At this time, the transmission rod rotates clockwise. At the same time, the semi-annular rack is in meshing state with the second gear, and the central shaft will rotate clockwise accordingly. When the semi-annular rack rotates clockwise to a certain angle, that is, after the feed port is sealed, the right end of the semi-annular rack is disengaged from the second gear and no longer rotates accordingly. Due to the action of the ratchet, the central shaft will not rotate with the transmission rod, so that after the feed port is closed, the central shaft will no longer rotate, and will not affect the rotation of the transmission rod, and will not interfere with the stirring.

[0011] Furthermore, a horizontal sector-shaped partition is provided on the upper left side of the interior of the smelting chamber. The central end of the sector-shaped partition is fixedly connected to the annular end surface of the central shaft. An annular connecting groove is provided on the upper side of the annular inner wall of the smelting chamber. The sector-shaped end of the sector-shaped partition is installed in the connecting groove with a clearance fit. The sector-shaped cross-section of the sector-shaped partition covers the feed port. The closure state of the feed port is controlled by the sector-shaped partition being positioned in different positions as the central shaft rotates.

[0012] Furthermore, a sealing coating is fixedly provided on the upper end wall of the smelting chamber. The thickness of the sealing coating is equal to the gap between the upper end wall of the smelting chamber and the sector-shaped partition. The sealing coating fills the gap between the upper end wall of the smelting chamber and the sector-shaped partition, ensuring sealing during the smelting process. The generated high-pressure environment can accelerate the smelting process. In the sealed state, the ingress of air is reduced, reducing the proportion of tin oxidized after melting during the smelting process, thereby improving production efficiency.

[0013] Advantageously, an electrically controlled valve is disposed within the discharge port, a horizontally positioned filter plate is positioned in the middle of the filter chamber, and a liquid infusion tube is disposed at the center of the lower end surface of the kettle body, communicating with the filter chamber. The tube body of the liquid infusion tube is provided with an infusion valve. The tin slag processing device integrates smelting and filtration, reducing oxidation during the transfer of the tin slag solution, minimizing raw material loss, and lowering production costs.

[0014] More advantageously, a removable annular disassembly plate is provided on the upper side of the front end wall of the filter chamber. The left and right ends of the disassembly plate are connected to the kettle body by bolts. An annular stepped groove is provided horizontally between the disassembly plate and the inner wall of the filter chamber, and the annular end of the filter plate is located within the stepped groove. After filtration is completed, the disassembly plate can be removed by unscrewing the bolts, and the filter plate and the metal residue and tin oxide left on the filter plate can be removed together, thereby facilitating cleaning and replacement of the filter plate.

[0015] Furthermore, a sealed space is provided inside the pressure stabilizer, and the sealed space is connected to the smelting chamber through the exhaust hole at its lower end wall. An air inlet is provided at the upper end of the pressure stabilizer, and the air inlet connects the sealed space with the outside space. An air pressure valve is provided inside the air inlet, and a horizontally placed sealing plate is provided on the lower side of the interior of the sealed space. The connection port between the first air pipe and the sealed space is located on the lower side of the rear end wall of the sealed space, and the diameter of the connection port between the first air pipe and the sealed space is smaller than the thickness of the sealing plate. During use, the sealed space is pressurized through the air inlet so that the air pressure in the sealed space is equal to the maximum pressure value of the smelting chamber. The air pressure in the sealed space pushes the sealing plate to move downward, thereby blocking the connection between the first air pipe and the sealed space and the exhaust hole, ensuring the sealing of the smelting chamber and providing a suitable high-pressure environment for smelting. As the temperature rises, the air pressure in the smelting chamber increases to a critical value, the air pressure in the smelting chamber is greater than the air pressure in the sealed space. Under the action of air pressure, the sealing plate moves upward, the exhaust hole and the connection between the first air pipe and the sealed space are in an open state, and the gas in the smelting chamber will be discharged through the exhaust hole and the first air pipe, ensuring the safe use of the device.

[0016] Furthermore, the first air pipe connects the induction solenoid valve and the voltage stabilizer, the second air pipe connects the induction solenoid valve and the smelting chamber, the third air pipe connects the induction solenoid valve and the filter chamber, the induction solenoid valve is a four-way valve, and the induction solenoid valve is connected to the external space, and the four connection ports of the induction solenoid valve are all equipped with built-in solenoid valves. During the smelting process, the electromagnetic valve connected to the induction solenoid valve and the external space and the electromagnetic valve connected to the second air pipe are closed to ensure that the high-temperature and high-pressure gas generated by the pressure overload of the smelting chamber enters the filter chamber, thereby preheating the filter chamber and realizing energy recovery and utilization; after the smelting is completed, the electromagnetic valve connected to the induction solenoid valve and the second air pipe is opened, and the smelted liquid enters the filter chamber through the discharge port for filtration, while the gas in the filter chamber enters the smelting chamber through the third air pipe and the second air pipe, avoiding the air in the filter chamber from entering the smelting chamber through the discharge port in the form of bubbles, thereby reducing the oxidation caused by the contact between liquid tin and air; after the filtered liquid tin is transmitted away through the infusion tube, the air pressure in the smelting chamber and the filter chamber becomes low. In order to prevent the fan-shaped partition from being difficult to open under the negative pressure state, the electromagnetic valve connected to the induction solenoid valve and the external space is opened, so that the smelting chamber and the filter chamber are in a normal pressure state.

[0017] The beneficial effects of the present invention are as follows: a tin slag treatment device for tin ingot processing uses a power transmission device to control the sealing state of the smelting chamber, which is convenient for sealing after the tin slag is placed in the smelting chamber. At the same time, the power transmission device provides power to the stirring mechanism, which stirs continuously during the smelting process. In the process of the five-angled paddles on the left and right sides revolving around the center line of the transmission rod, the five-angled paddles will be paddled by the fixed paddle to rotate at one angle, the revolution is clockwise, and the rotation is counterclockwise, which can make the tin slag solution in the smelting chamber flow disorderly, facilitate the spread of heat, and make the tin slag solution in the smelting chamber flow disorderly. The tin slag solution is heated more evenly, which facilitates the melting of the tin in the tin slag. The tin slag processing device completes smelting and filtration in an integrated manner, reducing oxidation during the transfer of the tin slag solution, reducing raw material loss, and reducing production costs. The air pressure system can prevent the air pressure in the smelting chamber from being too high while ensuring the sealing of the smelting chamber, thereby avoiding damage to the device. During the smelting process, the air pressure system sends the excess high-temperature and high-pressure gas generated by the heating of the smelting chamber into the filter chamber, heating the filter chamber in advance, providing a suitable temperature environment for the filtration of the tin slag solution, and achieving rational use of energy.

[0032] like Figures 1 to 3As shown, a tin slag treatment device for tin ingot processing includes a kettle body 1, a power transmission device 2 and an air pressure system 3. An annular support plate 4 is fixedly provided on the lower side of the annular end surface of the kettle body 1, and the support plate 4 is supported by support legs 5 distributed circumferentially on its lower end surface. A smelting chamber 6 is provided on the upper side of the interior of the kettle body 1, and a feed port 12 is provided on the left side of the upper end wall of the smelting chamber 6. The feed port 12 connects the smelting chamber 6 and the external space. A filter chamber 13 is provided on the lower side of the interior of the kettle body 1, and a lower filter chamber 13 is provided at the center of the upper end wall of the filter chamber 13. The feed port 33, the feed port 33 is connected to the smelting chamber 6 and the filter chamber 13, the power transmission device 2 is located at the center of the upper end surface of the kettle body 1, and a stirring mechanism is provided inside the smelting chamber 6. The power transmission device 2 is connected to the stirring mechanism by power, and the pneumatic system 3 includes a first air pipe 7, a second air pipe 8, a third air pipe 9 and an induction solenoid valve 10 and a voltage stabilizer 11 fixed on the rear side of the upper end surface of the kettle body 1. The voltage stabilizer 11 is connected to the smelting chamber 6 and the filter chamber 13 through the first air pipe 7, the second air pipe 8, the third air pipe 9 and the induction solenoid valve 10. The power transmission device 2 is used to control the sealing state of the smelting chamber 6, which is convenient for sealing after the tin slag is placed in the smelting chamber 6. At the same time, the power transmission device 2 provides power for the stirring mechanism, which stirs continuously during the smelting process to make the tin slag solution heated more evenly, which is convenient for melting the tin in the tin slag. The tin slag processing device completes smelting and filtration in an integrated manner, reduces oxidation during the transfer of the tin slag solution, reduces raw material loss, and reduces production costs. The air pressure system 3 can prevent the air pressure in the smelting chamber 6 from being too high while ensuring the sealing of the smelting chamber 6, thereby avoiding damage to the device. During the smelting process, the excess high-temperature and high-pressure gas generated by the heating of the smelting chamber 6 is sent into the filter chamber 13 through the air pressure system 3, and the filter chamber 13 is heated in advance to provide a suitable temperature environment for the filtration of the tin slag solution, thereby achieving rational use of energy.

[0033] In a preferred embodiment, the power transmission device 2 includes a set-top box 14 fixed at the center position of the upper end surface of the kettle body 1, and a transmission space 15 is provided inside the set-top box 14. A transmission rod 16 is rotatably connected to the left side of the upper end wall of the transmission space 15, and a central axis 18 is rotatably provided at the lower end wall of the transmission space 15. The central axis 18 vertically penetrates the center position of the upper end wall of the smelting chamber 6 and extends into the smelting chamber 6. The central axis 18 is rotatably connected to the penetration point of the upper end wall of the smelting chamber 6, and the lower end of the transmission rod 16 vertically penetrates the central axis 18 and extends into the smelting chamber 6. The penetration point of the transmission rod 16 and the central axis 18 is connected by a ratchet 17, and the lower connection between the transmission rod 16 and the central axis 18 is arranged. An elastic sealing ring is installed, and a motor 19 is fixedly provided on the right side of the upper end face of the set-top box 14. The motor core shaft of the motor 19 extends downward through the upper end wall of the transmission space 15 and is rotatably connected to the lower end wall of the transmission space 15. A first gear 21 and a second gear 22 are respectively provided on the upper and lower sides of the shaft body of the motor core shaft. The first gear 21 and the second gear 22 are both fixedly sleeved on the shaft body of the motor core shaft through the center position. A third gear 23 is fixedly sleeved on the upper side of the rod body of the transmission rod 16 at the same level as the first gear 21. The first gear 21 and the third gear 23 are meshed and transmitted. A semi-annular rack 24 is provided at the same level as the outer ring surface of the central shaft 18 and the second gear 22. The semi-annular rack 24 is meshed with the second gear 22. The motor 19 is used to provide power, and the cooperation of the first gear 21, the second gear 22, the third gear 23, the semi-annular rack 24 and the ratchet 17 enables the motor 19 to control the different rotation conditions of the transmission rod 16 and the central shaft 18 in different working states of forward rotation and reverse rotation, thereby achieving a motor-controlled closing state of the feed port 12 and the stirring operation, without the need for an additional power source, reducing the cost of the device.

[0034] Preferably, a horizontally placed strip plate 28 is provided on the upper side of the smelting chamber 6, the lower end of the transmission rod 16 is located inside the smelting chamber 6 and is fixedly connected to the center position of the upper end surface of the strip plate 28, and the left and right ends of the strip plate 28 are rotatably hoisted with a vertical downward rotating shaft 29, and the shaft body of the rotating shaft 29 is fixedly sleeved with a five-angled dial plate 30, such as Figure 4As shown, four medium-frequency electric heating plates 32 are distributed in an annular pattern within the annular inner wall of the smelting chamber 6. Four vertical fixed plates 31 are evenly distributed circumferentially within the annular interior of the smelting chamber 6. The distance between the centerline of the rotating shaft 29 and the vertices of the fixed plates 31 is less than the radius of the inscribed circle of the regular pentagon formed by the five corners of the pentagonal plates 30. As the pentagonal plates 30 on the left and right sides revolve around the centerline of the transmission rod 16, the fixed plates 31 toggle one angle of the pentagonal plates 30, causing them to rotate. The revolution is clockwise, while the rotation is counterclockwise. This can cause the tin slag solution in the smelting chamber 6 to flow in a disordered manner, facilitate heat dissipation, and ensure uniform heating.

[0035] In a preferred embodiment, Figure 5 As shown, the center lines of the transmission rod 16 and the central shaft 18 are on the same vertical line, the ratchet 17 is a one-way transmission structure and the forward rotation direction is counterclockwise rotation, the semi-annular rack 24 is arranged on the front annular surface of the central shaft 18, and the transmission ratio between the first gear 21 and the third gear 23 is the same as the transmission ratio between the second gear 22 and the semi-annular rack 24. Before the tin slag is put into the smelting chamber 6, the motor 19 is reversed and the motor core shaft rotates clockwise. At this time, the transmission rod 16 rotates counterclockwise, driving the central shaft 18 to rotate counterclockwise through the ratchet 17, so that the feed port 12 is opened. During the counterclockwise rotation of the central shaft 18, the right side of the semi-annular rack 24 will contact and mesh with the second gear 22. The same transmission ratio can ensure that the transmission of the two gear meshings does not interfere with each other; and after the tin slag is put into the smelting chamber 6, the motor 19 rotates forward and the motor core shaft rotates counterclockwise. At this time, the transmission rod 16 rotates counterclockwise. When the semi-annular rack 24 rotates clockwise, the semi-annular rack 24 is in meshing state with the second gear 22, and the central shaft 18 will rotate clockwise accordingly. When the semi-annular rack 24 rotates clockwise to a certain angle, that is, after the feed port 12 is sealed, the right end of the semi-annular rack 24 is disengaged from the second gear 22 and no longer rotates accordingly. Due to the action of the ratchet 17, the central shaft 18 will not rotate with the transmission rod 16, so that after the feed port 12 is closed, the central shaft 18 will no longer rotate, will not affect the rotation of the transmission rod 16, and will not interfere with the stirring.

[0036] As a preference, Figure 6 and Figure 7 As shown, a horizontal sector-shaped partition 25 is provided on the upper left side of the interior of the smelting chamber 6. The central end of the sector-shaped partition 25 is fixedly connected to the annular end surface of the central shaft 18. An annular connecting groove 26 is provided on the upper side of the annular inner wall of the smelting chamber 6. The sector-shaped end of the sector-shaped partition 25 is installed in the connecting groove 26 by a clearance fit. The sector-shaped cross-section of the sector-shaped partition 25 covers the feed port 12. The sector-shaped partition 25 is in different positions as the central shaft 18 rotates, thereby controlling the closed state of the feed port 12.

[0037] In a preferred embodiment, a sealing coating 27 is fixedly provided on the upper end wall of the smelting chamber 6. The thickness of the sealing coating 27 is equal to the gap between the upper end wall of the smelting chamber 6 and the sector-shaped partition 25. The sealing coating 27 fills the gap between the upper end wall of the smelting chamber 6 and the sector-shaped partition 25, ensuring sealing during the smelting process. The generated high-pressure environment can accelerate the smelting process. In the sealed state, the ingress of air is reduced, reducing the proportion of tin that is oxidized after melting during the smelting process, thereby improving production efficiency.

[0038] In a preferred embodiment, an electrically controlled valve 34 is disposed within the discharge port 33, a horizontally positioned filter plate 35 is disposed in the middle of the filter chamber 13, and a liquid infusion tube 36 is disposed at the center of the lower end surface of the kettle body 1. The liquid infusion tube 36 communicates with the filter chamber 13 and is provided with a liquid infusion valve 37. The tin slag processing device integrates smelting and filtration, reducing oxidation during the transfer of the tin slag solution, reducing raw material loss, and lowering production costs.

[0039] In a more preferred embodiment, Figure 8 As shown, a removable annular disassembly plate 38 is provided on the upper side of the front end wall of the filter chamber 13. The left and right ends of the disassembly plate 38 are connected to the kettle body 1 by bolts. An annular stepped groove is formed horizontally between the disassembly plate 38 and the inner wall of the filter chamber 13, and the annular end of the filter plate 35 is located within the stepped groove. After filtration is completed, the disassembly plate 38 is removed by unscrewing the bolts, and the filter plate 35 and the metal residue and tin oxide left on the filter plate 35 can be removed together, facilitating the cleaning and replacement of the filter plate 35.

[0040] Preferably, a sealed space 39 is provided inside the pressure stabilizer 11, and the sealed space 39 is connected to the smelting chamber 6 through the exhaust hole 40 at its lower end wall. An air inlet 41 is provided at the upper end of the pressure stabilizer 11, and the air inlet 41 connects the sealed space 39 with the external space. An air pressure valve 42 is provided inside the air inlet 41, and a horizontally placed sealing plate 43 is provided on the lower side of the interior of the sealed space 39. The connection port of the first air pipe 7 and the sealed space 39 is located on the lower side of the rear end wall of the sealed space 39, and the diameter of the connection port of the first air pipe 7 and the sealed space 39 is smaller than the thickness of the sealing plate 43. During use, the sealed space 39 is pressurized through the air inlet 41 so that the air pressure in the sealed space 39 is equal to the maximum pressure value of the smelting chamber 6. The air pressure in the sealed space 39 pushes the sealing plate 43 to move downward, thereby blocking the connection between the first air pipe 7 and the sealed space 39 and the exhaust hole 40, ensuring the sealing of the smelting chamber 6 and providing a suitable high-pressure environment for smelting. As the temperature rises, the air pressure in the smelting chamber 6 increases to a critical value, and the air pressure in the smelting chamber 6 is greater than the air pressure in the sealed space 39. Under the action of air pressure, the sealing plate 43 moves upward, and the exhaust hole 40 and the connection between the first air pipe 7 and the sealed space 39 are in an open state. The gas in the smelting chamber 6 will be discharged through the exhaust hole 40 and the first air pipe 7 to ensure the safe use of the device.

[0041] More preferably, the first air pipe 7 connects the induction solenoid valve 10 and the voltage stabilizer 11, the second air pipe 8 connects the induction solenoid valve 10 and the smelting chamber 6, the third air pipe 9 connects the induction solenoid valve 10 and the filter chamber 13, the induction solenoid valve 10 is a four-way valve, and the induction solenoid valve 10 is connected to the external space, and the four connection ports of the induction solenoid valve 10 are all equipped with electromagnetic valves. During the smelting process, the electromagnetic valve connected to the external space by the induction solenoid valve 10 and the electromagnetic valve connected to the second air pipe 8 are closed to ensure that the high-temperature and high-pressure gas generated by the pressure overload of the smelting chamber 6 enters the filter chamber 13, thereby preheating the filter chamber 13 and realizing energy recovery and utilization; after the smelting is completed, the electromagnetic valve connected to the induction solenoid valve 10 and the second air pipe 8 is opened, and the smelted liquid enters the filter chamber 13 through the discharge port 33 for filtration, while the gas in the filter chamber 13 enters the smelting chamber 6 through the third air pipe 9 and the second air pipe 8, avoiding the air in the filter chamber 13 from entering the smelting chamber 6 through the discharge port 33 in the form of bubbles, thereby reducing the oxidation caused by the contact between the liquid tin and the air; after the filtered liquid tin is transmitted away through the infusion pipe 36, the air pressure in the smelting chamber 6 and the filter chamber 13 becomes low. In order to prevent the fan-shaped partition 25 from being difficult to open under the negative pressure state, the electromagnetic valve connected to the induction solenoid valve 10 and the external space is opened, so that the smelting chamber 6 and the filter chamber 13 are in a normal pressure state.

[0042] The embodiment of the present invention is as follows: the fan-shaped partition 25 is in different positions as the central shaft 18 rotates to control the closing state of the feed port 12. Before the tin slag is put into the smelting chamber 6, the motor 19 is reversed and the motor core shaft rotates clockwise. At this time, the transmission rod 16 rotates counterclockwise, and the ratchet 17 drives the central shaft 18 to rotate counterclockwise, so that the feed port 12 is opened. During the counterclockwise rotation of the central shaft 18, the right side of the semi-annular rack 24 contacts and meshes with the second gear 22. The same transmission ratio can ensure that the transmission of the two gear meshing does not interfere with each other; and when the tin slag is put into the smelting chamber 6, the motor 19 is reversed and the motor core shaft rotates clockwise. At this time, the transmission rod 16 rotates counterclockwise, and the ratchet 17 drives the central shaft 18 to rotate counterclockwise, so that the feed port 12 is opened. During the counterclockwise rotation of the central shaft 18, the right side of the semi-annular rack 24 contacts and meshes with the second gear 22. The same transmission ratio can ensure that the transmission of the two gear meshing does not interfere with each other; After entering the smelting chamber 6, the motor 19 rotates forward and the motor core shaft rotates counterclockwise. At this time, the transmission rod 16 rotates clockwise. At the same time, the semi-annular rack 24 is in meshing state with the second gear 22, and the central shaft 18 will rotate clockwise accordingly. When the semi-annular rack 24 rotates clockwise to a certain angle, that is, after the feed port 12 is sealed, the right end of the semi-annular rack 24 is disengaged from the second gear 22 and no longer rotates therewith. The fan-shaped partition 25 rotates to the left and is limited in the connecting groove 26. Under the unidirectional transmission action of the ratchet, the central shaft 18 will not rotate with the transmission rod 16, so that the feed port 12 is sealed. After the material port 12 is closed, the central shaft 18 no longer rotates, and will not affect the rotation of the transmission rod 16, and will not interfere with the stirring. When the transmission rod 16 rotates, the five-angled dial plates 30 on the left and right sides revolve around the center line of the transmission rod 16. The five-angled dial plates 30 will be toggled by the fixed dial plate 31 at one angle and rotate on their own. The revolution is clockwise and the rotation is counterclockwise, which can make the tin slag solution in the smelting chamber 6 flow disorderly, facilitate the spread of heat, and make it heated evenly. After the smelting is completed, the electromagnetic valve connected to the induction electromagnetic valve 10 and the second air pipe 8 is opened, and the smelting is completed. The liquid enters the filter chamber 13 through the discharge port 33 for filtration, and the gas in the filter chamber 13 enters the smelting chamber 6 through the third air pipe 9 and the second air pipe 8, preventing the air in the filter chamber 13 from entering the smelting chamber 6 through the discharge port 33 in the form of bubbles, thereby reducing the oxidation caused by the contact between the liquid tin and the air; after the filtered liquid tin is transmitted away through the infusion pipe 36, the air pressure in the smelting chamber 6 and the filter chamber 13 becomes low. In order to prevent the fan-shaped partition 25 from being difficult to open under the negative pressure state, the electromagnetic valve connected to the external space of the induction solenoid valve 10 is opened, so that the smelting chamber 6 and the filter chamber 13 are in a normal pressure state.

[0043] Beneficial effects of the present invention: A tin slag processing device for tin ingot processing uses a power transmission device 2 to control the sealing state of the smelting chamber 6, which is convenient for sealing after the tin slag is placed in the smelting chamber 6. At the same time, the power transmission device 2 provides power for the stirring mechanism, which stirs continuously during the smelting process. In the process of the five-angled dial plates 30 on the left and right sides revolving around the center line of the transmission rod 16, the five-angled dial plates 30 will be rotated by one angle by the fixed dial plate 31. The revolution is clockwise and the rotation is counterclockwise, which can make the tin slag solution in the smelting chamber 6 flow disorderly, facilitating the spread of heat. , so that the tin slag solution is heated more evenly, which is convenient for melting the tin in the tin slag. The tin slag processing device completes smelting and filtration in an integrated manner, reduces oxidation during the transfer of the tin slag solution, reduces raw material loss, and reduces production costs. The air pressure system 3 can prevent the air pressure in the smelting chamber 6 from being too high while ensuring the sealing of the smelting chamber 6, thereby avoiding damage to the device. During the smelting process, the excess high-temperature and high-pressure gas generated by the heating of the smelting chamber 6 is sent into the filter chamber 13 through the air pressure system 3, and the filter chamber 13 is heated in advance to provide a suitable temperature environment for the filtration of the tin slag solution, thereby achieving rational use of energy.
