High-temperature melting equipment for resource utilization of tungsten slag

Abstract

The present application belongs to the technical field of tungsten slag recycling, and discloses a high-temperature melting equipment for tungsten slag resource utilization; the melting furnace is internally provided with an electric heating wire on the inner wall. The separation assembly is arranged to separate the blocky tungsten slag and the powdery tungsten slag during the process of putting the tungsten slag into the melting furnace. The tungsten slag mixture is poured from the feeding pipe into the feeding area between the first conical plate and the conical filter screen. The powdery tungsten slag directly passes through the conical filter screen and falls into the lower internal area. The blocky tungsten slag slides downward along the conical filter screen under the action of gravity. Meanwhile, under the action of centrifugal force and inertia, the blocky tungsten slag is thrown out of the discharge port and thrown to the external area. Since the blocky tungsten slag in the external area is close to the inner wall and the partition plate of the melting furnace, the tungsten slag in the external area is heated quickly, thereby accelerating the melting of the blocky tungsten slag and realizing the uniform melting of the tungsten slag in the melting furnace.

Description

Technical Field

[0001] This invention relates to the field of tungsten slag recycling technology, and more specifically, to a high-temperature melting device for the resource utilization of tungsten slag. Background Technology

[0002] The smelting and processing of tungsten generates a large amount of tungsten slag, which typically contains valuable tungsten elements as well as other metallic and non-metallic impurities. To effectively utilize these resources and reduce environmental pollution, the resource utilization of tungsten slag is crucial. Currently, the main method for resource utilization of tungsten slag is through high-temperature melting equipment. This equipment provides a high-temperature environment, allowing the metallic elements in the tungsten slag to melt and separate, thereby achieving resource recovery and reuse.

[0003] Existing high-temperature melting equipment typically includes a melting furnace body and a stirring assembly. The inner wall of the melting furnace is equipped with heating wires to heat the tungsten slag. The stirring assembly can stir the tungsten slag during the melting process, which can accelerate the melting of the tungsten slag. However, since the tungsten slag produced by current smelting usually includes powdered tungsten slag and block tungsten slag, the current high-temperature melting equipment cannot separate the powdered tungsten slag and block tungsten slag. As a result, the two types of tungsten slag are mixed together for heating. After the powdered tungsten slag melts, the block tungsten slag may not have melted yet, resulting in uneven melting of the tungsten slag. Summary of the Invention

[0004] This invention addresses the problem in the prior art where current high-temperature melting equipment cannot separate powdered and blocky tungsten slag, resulting in uneven melting of tungsten slag. Instead, it proposes a high-temperature melting device for the resource utilization of tungsten slag.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature melting device for the resource utilization of tungsten slag, comprising a melting furnace, wherein an electric heating wire is arranged inside the inner wall of the melting furnace, a feed pipe and a discharge pipe are connected and fixedly connected to the melting furnace, a motor is fixedly connected to the melting furnace via a support plate, a stirring shaft is rotatably connected to the middle of the melting furnace, a first gear that meshes with each other is fixedly connected to the outer wall of the stirring shaft and the output shaft of the motor, and a plurality of stirring rods are fixedly connected to the outer wall of the stirring shaft, and further comprising: The separation component is installed on the stirring shaft and the feed pipe.

[0008] Furthermore, the input component includes an annular plate slidably connected to the outer wall of the connecting column, a second conical plate fixedly connected to the annular plate, the second conical plate being adapted to the conical filter screen, a plurality of springs fixedly connected between the second conical plate and the first conical plate, a plurality of connecting ropes penetrating the conical filter screen fixedly connected to the bottom of the annular plate, a connecting ball fixedly connected to one end of the connecting ropes, a plurality of guide blocks fixedly connected to the bottom of the conical filter screen, the connecting ropes passing through the guide blocks, the connecting ball being located at the discharge port, and a plurality of ribs provided on the connecting ball.

[0009] Furthermore, the exhaust assembly includes multiple exhaust channels formed inside the stirring shaft. A circular shell is rotatably connected to the outer wall of the stirring shaft. The exhaust channels communicate with the circular shell. A connecting pipe is fixedly connected to the circular shell. A suction device is installed at one end of the connecting pipe. The suction device is fixedly connected to the feed pipe. An exhaust pipe is installed on the suction device.

[0010] Furthermore, the feeding assembly includes a feeding channel formed inside the stirring shaft, a rotating block rotatably connected to the top of the stirring shaft and communicating with the feeding channel, an L-shaped block fixed between the rotating block and the annular shell, a horizontal bar fixed to the inner wall of the rotating block, a vertical bar fixed to the bottom of the horizontal bar, and multiple fixing rods fixed to the outer wall of the vertical bar.

[0011] Furthermore, a fixing seat is fixedly connected to the inner wall of the feeding channel, and an opening is provided in the middle of the fixing seat. An elastic connecting line is fixedly connected to the inner wall of the feeding channel, and a sealing ball for sealing the opening is fixedly connected to one end of the connecting line.

[0012] Furthermore, the auxiliary stirring assembly includes a first rotating shaft fixed to the bottom of the partition plate, the first rotating shaft being rotatably connected to the bottom of the melting furnace, a second gear being fixed to the bottom end of the first rotating shaft, a rotating ring plate being rotatably connected to the bottom of the melting furnace, an annular gear meshing with multiple second gears being fixed to the outer wall of the rotating ring plate, a second rotating shaft being rotatably connected to the bottom of the melting furnace, a third gear meshing with the annular gear being fixed to the bottom end of the second rotating shaft, a worm gear being fixed to the bottom of the second rotating shaft, a worm being rotatably connected to the bottom of the melting furnace via a support plate, the worm meshing with the worm gear, a fourth gear being fixed to one end of the worm, two external threads being formed on the outer wall of the bottom end of the stirring shaft, the two external threads having opposite thread directions, a lifting plate being threaded to the stirring shaft via the external threads, a guide rod penetrating the lifting plate being fixed to the bottom of the melting furnace, an electric push rod being fixed to the lifting plate, a T-shaped plate being fixed to the output end of the electric push rod, a rack being fixed to the T-shaped plate, the rack being directly opposite the fourth gear.

[0013] The technical effects and advantages of the high-temperature melting equipment for the resource utilization of tungsten slag of this invention are as follows: (1) By setting up a separation component, in order to separate lumpy tungsten slag and powdery tungsten slag during the process of feeding tungsten slag into the melting furnace, the motor is started to drive the stirring shaft to rotate. The stirring shaft drives the conical filter screen and the first conical plate to rotate, and the tungsten slag mixture is poured from the feed pipe into the feeding area between the first conical plate and the conical filter screen. The powdery tungsten slag will directly pass through the conical filter screen and fall into the inner area below. The lumpy tungsten slag is blocked by the conical filter screen and cannot fall down. Under the action of gravity, it slides down along the conical filter screen. At the same time, under the action of centrifugal force, the lumpy tungsten slag is thrown out from the discharge port and thrown to the outer area. Since the lumpy tungsten slag in the outer area is closer to the inner wall and partition of the melting furnace, the tungsten slag in the outer area heats up faster, thereby accelerating the melting of the lumpy tungsten slag. Although the powdery tungsten slag in the inner area is farther from the partition and the inner wall of the melting furnace, the powdery tungsten slag is easily heated to a molten state, thus achieving a more uniform melting of the tungsten slag in the melting furnace.

[0014] (2) By setting up the feeding component, when there is a lot of blocky tungsten slag in the outer zone, the stirring shaft is driven by the motor to speed up the rotation. The increased rotation speed of the stirring shaft can drive the rotation speed of the conical filter screen to increase. The centrifugal force on the connecting ball increases. Under the action of centrifugal force, the connecting ball leaves the guide block. The connecting ball pulls the ring plate and the second conical plate through the connecting rope, causing the second conical plate to move downward. The second conical plate covers the conical filter screen. The tungsten slag mixture fed into the feed pipe will be thrown out from the discharge port in a unified manner, thereby throwing the powdery tungsten slag into the outer zone. An appropriate amount of powdery tungsten slag can be fed into the outer zone. The powdery tungsten slag can fill the gaps between the blocky tungsten slag, preventing the gaps between the blocky tungsten slag from causing slow heat transfer. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1 - Figure 9 A high-temperature melting device for the resource utilization of tungsten slag includes a melting furnace 1. Heating wires are installed inside the inner wall of the melting furnace 1. A feed pipe 2 and a discharge pipe are connected and fixed to the melting furnace 1. A motor 3 is fixed to the melting furnace 1 via a support plate. A stirring shaft 4 is rotatably connected to the middle of the melting furnace 1. A first gear 5, meshing with each other, is fixed to the outer wall of the stirring shaft 4 and the output shaft of the motor 3. Multiple stirring rods 6 are fixed to the outer wall of the stirring shaft 4. The device also includes: The separation component is installed on the stirring shaft 4 and the feed pipe 2. The separation component is used to separate lumpy tungsten slag and powdered tungsten slag. The separation component is equipped with a feeding component for feeding powdered tungsten slag into the lumpy tungsten slag zone. The exhaust assembly and the feeding assembly are mounted on the stirring shaft 4. The exhaust assembly is used to exhaust the waste gas generated during the tungsten slag melting process, and the feeding assembly is used to add flux into the melting furnace 1. An auxiliary stirring assembly is installed at the bottom of the melting furnace 1 and is used to assist in stirring the tungsten slag. In operation, the tungsten slag mixture to be melted is first poured into the melting furnace 1 through the feed pipe 2. The tungsten slag is separated by the separation component, separating the lumpy tungsten slag from the powdered tungsten slag. The lumpy tungsten slag is guided to the vicinity of the inner wall of the melting furnace 1, while the powdered tungsten slag is guided to the center of the melting furnace 1. The heating wire and motor 3 are turned on. The heating wire heats the tungsten slag in the melting furnace 1. The motor 3 drives the stirring shaft 4 to rotate through two first gears 5. The stirring shaft 4 drives multiple stirring rods 6 to rotate. The stirring rods 6 can stir the tungsten slag, which can accelerate the heating of the tungsten slag. Since the heating wire is set inside the inner wall of the melting furnace 1, the lumpy tungsten slag near the inner wall of the melting furnace 1 heats up faster, making the lumpy tungsten slag and powdered tungsten slag melt more evenly. During the heating process, the exhaust component can discharge the waste gas generated during the heating process. The feeding component can add flux to assist in the melting of the tungsten slag. The auxiliary stirring component can stir the lumpy tungsten slag and powdered tungsten slag.

[0019] Reference Figure 2The bottom of the melting furnace 1 is provided with multiple baffles 7, each containing a heating wire. The multiple baffles 7 form a closed ring. The outer side of the closed ring is designated as an outer zone 701, which is used to place blocky tungsten slag. The inner side of the closed ring is designated as an inner zone 702, which is used to place powdered tungsten slag. An auxiliary stirring component is used to drive the baffles 7 to rotate reciprocally. The tungsten slag mixture can be separated by a separation component. The blocky tungsten slag is guided to the outer zone 701, making it evenly distributed in the outer zone 701, while the powdered tungsten slag is guided to the inner zone 702, making it evenly distributed in the inner zone 702. This achieves separate heating of the blocky and powdered tungsten slag, resulting in more uniform overall heating of the tungsten slag. The auxiliary stirring component can drive the multiple baffles 7 to rotate reciprocally, which can stir the blocky and powdered tungsten slag and accelerate the heating of the tungsten slag.

[0020] Reference Figure 2 , Figure 4 and Figure 5 The separation assembly includes a conical filter screen 8 fixed to the outer wall of the stirring shaft 4. A first conical plate 9 is rotatably connected to the bottom outer wall of the feed pipe 2. The first conical plate 9 and the conical filter screen 8 are fixedly connected by multiple connecting posts 10. The area between the first conical plate 9 and the conical filter screen 8 is set as a feeding zone. The bottom end of the feed pipe 2 extends into the feeding zone. The area between the edge of the first conical plate 9 and the edge of the conical filter screen 8 is set as a discharge port. The tungsten slag mixture is poured into the melting furnace 1 through the feed pipe 2. When the slag enters the feeding zone, the tungsten slag falls onto the conical filter screen 8, while the powdered tungsten slag passes directly through the conical filter screen 8 and falls into the inner zone 702. The motor 3 is started to drive the stirring shaft 4 to rotate, which in turn drives the conical filter screen 8 and the first conical plate 9 to rotate. The lumpy tungsten slag slides down the conical filter screen 8 and is discharged from the outlet. Under the action of centrifugal force and inertia, the lumpy tungsten slag is evenly thrown into the outer zone 701, thus achieving the separation of lumpy tungsten slag and powdered tungsten slag.

[0021] Reference Figure 4 , Figure 5 and Figure 6The input assembly includes an annular plate 11 slidably connected to the outer wall of the connecting column 10. A second conical plate 12 is fixedly connected to the annular plate 11. The second conical plate 12 is adapted to the conical filter screen 8. A plurality of springs 13 are fixedly connected between the second conical plate 12 and the first conical plate 9. A plurality of connecting ropes 14 penetrating the conical filter screen 8 are fixedly connected to the bottom of the annular plate 11. A connecting ball 15 is fixedly connected to one end of each connecting rope 14. A plurality of guide blocks 16 are fixedly connected to the bottom of the conical filter screen 8. The connecting rope 14 passes through the guide block 16, and the connecting ball 15 is located at the discharge port. The connecting ball 15 is equipped with multiple ribs 1501. During the process of tungsten slag entering the feeding zone, the separation component can distinguish between blocky and powdered tungsten slag for easy heating. When there is a large amount of blocky tungsten slag in the outer zone 701, an appropriate amount of powdered tungsten slag needs to be added to the outer zone 701 to prevent large gaps between the blocky tungsten slag from affecting heating efficiency. The powdered tungsten slag can fill the gaps between the blocky tungsten slag. The stirring is driven by the motor 3. The rotation of shaft 4 increases its speed, which in turn increases the speed of the conical filter screen 8. This increased speed leads to greater centrifugal force on the connecting balls 15, causing them to be thrown outwards. The connecting balls 15, via connecting rope 14, pull the annular plate 11 and the second conical plate 12 downwards. The spring 13 is stretched, allowing the second conical plate 12 to cover the conical filter screen 8, preventing further drop of powdery tungsten slag. Simultaneously, the second conical plate 12 covers and presses against the conical filter screen 8, preventing any residue stuck in the screen from falling out. The tungsten slag inside the holes of the filter screen 8 is squeezed down. After the second conical plate 12 covers the conical filter screen 8, the falling tungsten slag mixture is guided to the discharge port by the second conical plate 12. Under the action of centrifugal force and inertia, it is thrown to the outer area 701. The powdered tungsten slag can fill the gaps between the blocky tungsten slag. By setting the baffles 1501, during the separation of blocky tungsten slag and powdered tungsten slag, the baffles 1501 can initially crush the sliding blocky tungsten slag. When the blocky tungsten slag hits the baffles 1501, the blocky tungsten slag may be crushed.

[0022] Reference Figure 3 and Figure 5 The exhaust assembly includes multiple exhaust channels 17 formed inside the stirring shaft 4. A circular shell 18 is rotatably connected to the outer wall of the stirring shaft 4. The exhaust channels 17 communicate with the circular shell 18. A connecting pipe 19 is fixedly connected to the circular shell 18. A suction device 20 is installed at one end of the connecting pipe 19. The suction device 20 is fixedly connected to the feed pipe 2. An exhaust pipe 21 is installed on the suction device 20. A large amount of waste gas is generated during the heating of tungsten slag. When the suction device 20 is started, it can suck air from the circular shell 18 through the connecting pipe 19. The circular shell 18 sucks gas from inside the melting furnace 1 through the exhaust channels 17, and the waste gas generated during heating can be sucked out and discharged to the external waste gas treatment equipment through the exhaust pipe 21.

[0023] Reference Figure 5 and Figure 7 The feeding assembly includes a feeding channel 22 formed inside the stirring shaft 4. A rotating block 23 communicating with the feeding channel 22 is rotatably connected to the top of the stirring shaft 4. An L-shaped block 24 is fixed between the rotating block 23 and the annular shell 18. A horizontal bar 25 is fixed to the inner wall of the rotating block 23, and a vertical bar 26 is fixed to the bottom of the horizontal bar 25. Multiple fixing rods 27 are fixed to the outer wall of the vertical bar 26. During the heating process of tungsten slag, flux is added to the feeding channel 22 through the rotating block 23. The flux enters the melting furnace 1 through the feeding channel 22. At the same time, the motor 3 drives the stirring shaft 4 to rotate. The stirring shaft 4 rotates relative to the rotating block 23. Since the rotating block 23 is fixed to the annular shell 18 through the L-shaped block 24, the stirring shaft 4 rotates relative to the horizontal bar 25, the vertical bar 26 and the fixing rods 27. The fixing rods 27 can clear the feeding channel 22 to prevent the flux from getting blocked.

[0024] Reference Figure 7 The inner wall of the feeding channel 22 is fixedly connected to a fixing seat 28, and the fixing seat 28 has an opening in the middle. The inner wall of the feeding channel 22 is fixedly connected to an elastic connecting line 29, and one end of the connecting line 29 is fixedly connected to a sealing ball 30 for sealing the opening. During the flux addition process, the flux can push the sealing ball 30 open, and the flux can be discharged from the opening of the fixing seat 28 into the melting furnace 1. The connecting line 29 is stretched. When no flux is added, the sealing ball 30 blocks the opening under the action of the connecting line 29, which can prevent the exhaust gas generated by heating from being discharged from the feeding channel 22 into the melting furnace 1.

[0025] Reference Figure 2 , Figure 8 and Figure 9The auxiliary stirring assembly includes a first rotating shaft 31 fixed to the bottom of the partition plate 7. The first rotating shaft 31 is rotatably connected to the bottom of the melting furnace 1. A second gear 32 is fixedly connected to the bottom end of the first rotating shaft 31. A rotating ring plate 33 is rotatably connected to the bottom of the melting furnace 1. A ring gear 34 that meshes with multiple second gears 32 is fixedly connected to the outer wall of the rotating ring plate 33. A second rotating shaft 35 is rotatably connected to the bottom of the melting furnace 1. A third gear 36 that meshes with the ring gear 34 is fixedly connected to the bottom end of the second rotating shaft 35. A worm gear 37 is fixedly connected to the bottom end of the furnace 35. A worm 38 is rotatably connected to the bottom of the furnace 1 via a support plate. The worm 38 meshes with the worm gear 37. A fourth gear 39 is fixedly connected to one end of the worm 38. Two external threads 40 are formed on the outer wall of the bottom end of the stirring shaft 4. The two external threads 40 have opposite thread directions. The stirring shaft 4 is threadedly connected to a lifting plate 41 via the external threads 40. A guide rod is fixedly connected to the bottom of the furnace 1, passing through the lifting plate 41. An electric push rod 42 is fixedly connected to the lifting plate 41. A T-shaped plate 43 is fixedly connected to the output end of motor 2. A rack 44 is fixedly connected to the T-shaped plate 43, and the rack 44 is directly opposite the fourth gear 39. During the heating process, the blocky tungsten slag and the powdered tungsten slag are heated separately. When the blocky tungsten slag is about to melt after a certain heating time, the electric push rod 42 is activated. The electric push rod 42 drives the T-shaped plate 43 and the rack 44 to move, so that the rack 44 meshes with the fourth gear 39. The motor 3 continuously drives the stirring shaft 4 to rotate. The stirring shaft 4 drives the lifting plate 41 to reciprocate in the vertical direction through the external thread 40. 1 can drive rack 44 to reciprocate, rack 44 drives fourth gear 39 to reciprocate, fourth gear 39 drives second rotating shaft 35 to reciprocate through worm 38 and worm wheel 37, second rotating shaft 35 drives third gear 36 to reciprocate, third gear 36 drives ring gear 34 and rotating ring plate 33 to reciprocate, ring gear 34 can drive multiple second gears 32 and first rotating shaft 31 to reciprocate, first rotating shaft 31 drives partition plate 7 to reciprocate, partition plate 7 can stir block tungsten slag and powder tungsten slag, and accelerate the melting of tungsten slag.

[0026] Working principle: In use, the tungsten slag mixture to be melted is first poured into the melting furnace 1 through the feed pipe 2. The tungsten slag is separated by the separation component, separating the blocky tungsten slag from the powdery tungsten slag. The blocky tungsten slag is guided to the vicinity of the inner wall of the melting furnace 1, while the powdery tungsten slag is guided to the center of the melting furnace 1. The heating wire and motor 3 are turned on. The heating wire heats the tungsten slag in the melting furnace 1. The motor 3 drives the stirring shaft 4 to rotate through two first gears 5. The stirring shaft 4 drives multiple stirring rods 6 to rotate. The stirring rods 6 can stir the tungsten slag, and stirring can accelerate the heating of the tungsten slag. Since the heating wire is set inside the inner wall of the melting furnace 1, the blocky tungsten slag near the inner wall of the melting furnace 1 heats up faster, so that the blocky tungsten slag and the powdery tungsten slag melt more evenly. During the heating process, the exhaust component can discharge the waste gas generated during the heating process. The feeding component can add flux to assist the melting of the tungsten slag. The auxiliary stirring component can stir the blocky tungsten slag and the powdery tungsten slag. The tungsten slag mixture can be separated by a separation component. The blocky tungsten slag is guided to the outer zone 701, so that the blocky tungsten slag is evenly distributed in the outer zone 701, and the powdery tungsten slag is guided to the inner zone 702, so that the powdery tungsten slag is evenly distributed in the inner zone 702. This allows the blocky tungsten slag and the powdery tungsten slag to be heated separately, so that the overall heating of the tungsten slag is more uniform. The auxiliary stirring component can drive multiple baffles 7 to reciprocate, and the reciprocating rotation of the baffles 7 can stir the blocky tungsten slag and the powdery tungsten slag, accelerating the heating of the tungsten slag. The tungsten slag mixture is poured into the melting furnace 1 through the feed pipe 2. The tungsten slag enters the feeding zone and falls onto the conical filter screen 8. The powdered tungsten slag will pass directly through the conical filter screen 8 and fall into the inner zone 702. The motor 3 is started to drive the stirring shaft 4 to rotate. The stirring shaft 4 can drive the conical filter screen 8 and the first conical plate 9 to rotate. The blocky tungsten slag will slide down the conical filter screen 8 and be discharged from the outlet. Under the action of centrifugal force and inertia, the blocky tungsten slag will be evenly thrown into the outer zone 701, realizing the separation of blocky tungsten slag and powdered tungsten slag. During the process of tungsten slag entering the feeding zone, the separation component can distinguish between blocky tungsten slag and powdery tungsten slag for easy heating. When there is a large amount of blocky tungsten slag in the outer zone 701, it is necessary to add an appropriate amount of powdery tungsten slag into the outer zone 701 to prevent the large gaps between the blocky tungsten slag from affecting the heating efficiency. The powdery tungsten slag can fill the gaps between the blocky tungsten slag. The motor 3 drives the stirring shaft 4 to rotate, and the stirring shaft 4 speed is increased. The stirring shaft 4 drives the conical filter screen 8 to rotate faster. The increased speed increases the centrifugal force of the connecting balls 15, and multiple connecting balls 15 are thrown outward. The connecting balls 15 pull the annular plate 11 and the second conical plate 12 downward through the connecting rope 14. The spring 13 is stretched, causing the second conical plate 12 to move downward. The second conical plate 12 can cover the conical filter screen 8 to prevent powdery tungsten slag from continuing to fall from the conical filter screen 8. At the same time, the second conical plate 12 covers and presses the conical filter screen 8, which can squeeze the tungsten slag stuck in the holes of the conical filter screen 8 down. After the second conical plate 12 covers the conical filter screen 8, the falling tungsten slag mixture will be guided by the second conical plate 12 to the discharge port. Under the action of centrifugal force and inertia, it will be thrown to the outer area 701. Powdery tungsten slag can fill the gaps between the blocky tungsten slag. By setting the baffle 1501, during the separation of blocky tungsten slag and powdery tungsten slag, the baffle 1501 can initially crush the sliding blocky tungsten slag. When the blocky tungsten slag hits the baffle 1501, the blocky tungsten slag may be crushed. A large amount of waste gas is generated during the heating of tungsten slag. The suction device 20 is started. The suction device 20 can suck air from the annular shell 18 through the connecting pipe 19. The annular shell 18 sucks gas from the inside of the melting furnace 1 through the exhaust channel 17. The waste gas generated during heating can be sucked out and discharged to the external waste gas treatment equipment through the exhaust pipe 21. During the heating process of tungsten slag, flux is added to the feeding channel 22 through the rotating block 23. The flux enters the melting furnace 1 through the feeding channel 22. At the same time, the motor 3 drives the stirring shaft 4 to rotate. The stirring shaft 4 rotates relative to the rotating block 23. Since the rotating block 23 is fixed to the annular shell 18 through the L-shaped block 24, the stirring shaft 4 rotates relative to the horizontal bar 25, the vertical bar 26 and the fixed bar 27. The fixed bar 27 can clear the feeding channel 22 to prevent the flux from getting blocked. During the flux addition process, the flux can push open the sealing ball 30, and the flux can be discharged from the port of the fixed seat 28 into the melting furnace 1. The connecting line 29 is stretched. When no flux is added, the sealing ball 30 blocks the port under the action of the connecting line 29, which can prevent the exhaust gas generated by heating from being discharged from the feeding channel 22 into the melting furnace 1. During the heating process, lumpy tungsten slag and powdered tungsten slag are heated separately. When the lumpy tungsten slag is about to melt after a certain heating time, the electric push rod 42 is activated. The electric push rod 42 drives the T-shaped plate 43 and the rack 44 to move, so that the rack 44 meshes with the fourth gear 39. The motor 3 continuously drives the stirring shaft 4 to rotate. The stirring shaft 4 drives the lifting plate 41 to reciprocate in the vertical direction through the external thread 40. The lifting plate 41 can drive the rack 44 to reciprocate. The rack 44 drives the fourth gear 39 to reciprocate. The fourth gear 39 drives the second rotating shaft 35 to reciprocate through the worm 38 and the worm wheel 37.
