[0015] Compared with the prior art, the present invention has the following beneficial effects: This argon purification device is equipped with a transmission mechanism, etc. When it is necessary to remove oxygen from the argon, the argon is introduced into the box through the air inlet pipe, and the oxygen can come into contact with the active metal particles through the filter plate. The oxygen can be adsorbed by the active metal particles and form oxide scale on their surface. After the deoxygenation is completed, the argon can enter the denitrification module through the first connecting pipe to continue purification. At the same time, the motor is started to rotate counterclockwise. The rotation of the motor drives the rotation of the rotating shaft and the toothed pulley, thereby driving the toothed belt to transport counterclockwise and driving the active metal particles to be transported through the filter plate. At the same time, it is convenient to remove the oxide scale on the surface of the active metal particles, thereby flipping the active metal particles, making the deoxygenation more efficient and more effective.

[0016] This argon purification device is provided with a cleaning mechanism, etc., and when it is necessary to clean the oxide scale on the surface of the active metal particles during the transportation of active metal particles, the transportation of the toothed belt is first stopped, and then the lifting block is driven to move back and forth up and down by the lifting module. At the same time, it can drive the movable plate and the steel wire rod to move back and forth up and down, and can extend the steel wire rod between the box body and the toothed belt. At this time, the oxide scale on the surface of the active metal particles can be frictionally cleaned to facilitate its shedding, thereby making the deoxidation efficiency higher and the effect better.

[0017] This argon purification device is provided with a pushing mechanism, etc., so that when the movable plate moves upward, the first movable block is driven to move upward by the second connecting plate and the second spring, and at the same time, the extrusion plate is driven to move upward by the third spring and the second movable block. When the extrusion plate abuts against the bottom of the baffle, the baffle can be pushed to move upward along the movable cover. At the same time, the first spring is gradually compressed, and at this time, the active metal particles between the two baffles can be squeezed. When the active metal particles are squeezed, the two baffles can be pushed to move away from each other. At the same time, the fourth spring is gradually compressed, so that the active metal particles can be gradually flattened. The second spring can be compressed and Moreover, when the second moving block moves upward, the pushing block can be driven to move upward through the L-shaped block. When the pushing block is against the side wall of the triangular block, the second moving block can be pushed to move away from the first moving block. The third spring is stretched. When the pushing block passes over the triangular block, the second moving block can be reset in the direction close to the first moving block under the action of the third spring. This reciprocating process can make the second moving block move back and forth, and drive the extrusion plate to move back and forth, and the rubber frame is deformed. At this time, the extrusion plate can rub the active metal particles back and forth, which facilitates the shedding of oxide scale on the surface of the active metal particles, making the cleaning efficiency higher and the effect better, thereby making the deoxidation efficiency higher and the effect better.

[0018] The argon purification device is provided with a collection mechanism, etc., and when the oxide scale on the surface of the active metal particles is cleaned, the fan is started to perform an exhaust operation. At this time, the exhaust operation can be performed through the exhaust hood, so that the shed oxide scale can enter the exhaust hood through the first through-hole, and then enter the filter box through the first L-shaped tube, the first fixed hood and the second connecting tube for filtration and collection. The filtered argon gas can enter the second L-shaped tube through the second fixed hood and return to the box through the blowing hood and the second through-hole, thereby facilitating the collection of the shed oxide scale. In addition, when the movable plate moves up and down, the argon gas can enter the second L-shaped tube through the second fixed hood and return to the box through the blowing hood and the second through-hole, thereby facilitating the collection of the shed oxide scale. During reciprocating movement, the first connecting plate and the mounting plate can drive multiple push pins to slide back and forth up and down in the sliding groove, thereby driving the driving rod to rotate, and driving the rotating rod and the triangular plate to rotate through the telescopic mechanism. At this time, the active metal particles can be stirred, making the absorption efficiency higher and the effect better, thereby improving the collection efficiency and effect of the oxide scale, and when the filter plate is against the side wall of the triangular plate, it can push the triangular plate and the rotating rod to move downward, and at the same time, drive the connecting plate to move downward, and the reset spring is compressed to ensure that the filter plate can pass over the triangular plate and the rotating rod.

[0019] This type of argon purification device, by setting up a feeding mechanism, etc., can squeeze the active metal particles temporarily stored in the storage box and enter the third L-shaped tube under the action of the gravity plate when in use. When there are gaps between the active metal particles of two adjacent baffles, the active metal particles in the third L-shaped tube can be automatically filled, which is more convenient and quick to use, and ensures the efficiency and effect of deoxygenation.

[0045] Working principle: During use, when it is necessary to remove oxygen from the argon gas, the argon gas is introduced into the box body 102 through the air inlet pipe 106, and the oxygen can contact the active metal particles through the filter plate 12. The oxygen can be adsorbed by the active metal particles and form oxide scale on their surface. After the deoxygenation is completed, the argon gas can enter the denitrification module 103 through the first connecting pipe 107 to continue purification. At the same time, the motor 1003 is started to rotate counterclockwise. The rotation of the motor 1003 drives the rotation of the rotating shaft 1001 and the toothed pulley 1002, thereby driving the toothed belt 11 to transport counterclockwise, and can drive the active metal particles to be transported through the filter plate 12. At the same time, it facilitates the shedding of the oxide scale on the surface of the active metal particles, thereby flipping the active metal particles, making the deoxygenation more efficient and more effective.

[0046] When the active metal particles are being transported, when it is necessary to clean the oxide scale on the surface of the active metal particles, the transport of the toothed belt 11 is stopped first, and then the lifting block 304 is driven to move up and down by the lifting module 303. At the same time, the movable plate 302 and the steel wire rod 301 can be driven to move up and down, and the steel wire rod 301 can be extended between the box body 102 and the toothed belt 11. At this time, the oxide scale on the surface of the active metal particles can be cleaned by friction, making it easier to fall off, making the deoxidation efficiency higher and the effect better.

[0047] When the moving plate 302 moves upward, the first moving block 502 is driven to move upward by the second connecting plate 501 and the second spring 510. At the same time, the extrusion plate 16 is driven to move upward by the third spring 513 and the second moving block 503. When the extrusion plate 16 contacts the bottom of the baffle 14, the baffle 14 can be pushed to move upward along the moving cover 13. At the same time, the first spring 17 is gradually compressed. At this time, the active metal particles between the two baffles 14 can be squeezed. When the active metal particles are squeezed, the two baffles 14 can be pushed to move away from each other. At the same time, the fourth spring 804 is gradually compressed, so that the active metal particles can be gradually flattened. The second spring 510 can be compressed, and when the second moving block 503 moves upward, it can be pushed by the L-shaped block 504 drives the pushing block 505 to move upward. When the pushing block 505 abuts against the side wall of the triangular block 507, it can push the second moving block 503 to move in the direction away from the first moving block 502. The third spring 513 is stretched. When the pushing block 505 passes over the triangular block 507, the second moving block 503 can be reset in the direction close to the first moving block 502 under the action of the third spring 513. This reciprocating motion can make the second moving block 503 move back and forth, and drive the extrusion plate 16 to move back and forth. The rubber frame 15 is deformed. At this time, the extrusion plate 16 can rub the active metal particles back and forth, which facilitates the shedding of the oxide scale on the surface of the active metal particles, making the cleaning efficiency higher and the effect better, thereby making the deoxidation efficiency higher and the effect better.

[0048] Furthermore, when the oxide scale on the surface of the active metal particles is cleaned, the fan 211 is started to perform the exhaust operation. At this time, the exhaust operation can be performed through the exhaust hood 201, so that the oxide scale that has fallen off can enter the exhaust hood 201 through the first through hole 202, and then enter the filter box 210 after passing through the first L-shaped tube 203, the first fixed cover 204 and the second connecting tube 212 for filtration and collection. The filtered argon gas can enter the second L-shaped tube 207 through the second fixed cover 208, and return to the box body 102 through the blowing cover 205 and the second through hole 206, so as to facilitate the collection of the oxide scale that has fallen off. Moreover, when the movable plate 302 moves up and down, it can be removed through the filter box 210. The first connecting plate 705 and the mounting plate 703 drive multiple push pins 704 to slide back and forth up and down in the sliding groove 702, thereby driving the driving rod 701 to rotate, and driving the rotating rod 403 and the triangular plate 404 to rotate through the telescopic mechanism. At this time, the active metal particles can be stirred, making the absorption efficiency higher and the effect better, thereby improving the collection efficiency and effect of the oxide scale, and when the filter plate 12 is against the side wall of the triangular plate 404, it can push the triangular plate 404 and the rotating rod 403 to move downward, and at the same time, drive the connecting plate 605 to move downward, and the reset spring 606 is compressed to ensure that the filter plate 12 can pass over the triangular plate 404 and the rotating rod 403.

[0049] During use, under the action of the gravity plate 903, the active metal particles temporarily stored in the storage box 901 can be squeezed and enter the third L-shaped tube 904. When there are gaps between the active metal particles of two adjacent baffles 14, the active metal particles in the third L-shaped tube 904 can be automatically filled, which is more convenient and quick to use, and ensures the efficiency and effect of deoxygenation.
