Most of these liquids are in demand in the pharmaceutical and chemical fields. In these fields, the amount of volatile, toxic, harmful or highly corrosive liquid materials required for the reaction is not large per batch, but continuous addition is often required.

[0003] The traditional way of adding materials is usually to manually weigh or measure liquid materials from storage tanks into barrels. Liquids are prone to leak or splash during the transfer process. Liquid volatilization can easily cause harm to workers and pose a serious threat to operators and the environment. Toxic or corrosive liquids may produce harmful gases when in contact with air, increasing operational risks.

[0045] The transport mechanism 410 includes a transport roller 411 , a clamping hydraulic machine 412 and a clamping block 413 . The transport roller 411 is fixedly arranged on the side wall of the sealed box body 1 , the clamping hydraulic machine 412 is arranged in pairs on the side wall of the sealed box body 1 , and the clamping block 413 is fixedly arranged on the output end of the clamping hydraulic machine 412 .

[0046] An observation window 102 is provided on the side wall of the sealed box body 1, and an electrical control panel 101 is fixedly provided on the side wall of the sealed box body 1.

[0047] The telescopic hydraulic device 211 is located in the middle of the fixing frame 212 , one end of the sewage pipe 222 located outside the sealed box body 1 is connected to the external exhaust gas treatment system, and the bottom end surface of the air inlet pipe 221 is lower than the bottom end surface of the overflow prevention cylinder 217 .

[0048] The anti-overflow gear 215 is meshed with the anti-overflow wheel teeth 216, the closing gear 506 is meshed with the sealing teeth 504, the bottom end of the anti-overflow cylinder 217 is provided with a thread, the power gear 438 is meshed with the rotating gear 437, the adjusting threaded rod 423 is connected to the adjusting base 424 by a thread, and the thread of the anti-overflow cylinder 217 is meshed with the thread of the outer wall of the nozzle of the transfer barrel.

[0049] When in use, first place the transfer barrel on the transport roller 411 outside the sealed box body 1, and the user can control the sealing motor 505 to rotate through the electrical control panel 101, and the two sealing plates 503 can move opposite to each other in the sealing groove 502 through the transmission of the closing gear 506 and the sealing tooth 504, so that the sealing port 501 can be opened, and then the user can push the transfer barrel to the middle of the two clamping blocks 413, and then the user can control the sealing motor 505 to reverse, and move the two sealing plates 503 relative to each other until the two sealing plates 503 are closed, and then the user can control the clamping hydraulic press 412 to work through the electrical control panel 101, and the extension of the clamping hydraulic press 412 will drive the clamping block 413 to move toward the transfer barrel, so as to fix the transfer barrel;

[0050] Then the user can control the adjustment motor 422 and the suspension electromagnet 436 through the electrical control panel 101. The adjustment threaded rod 423 is driven to make the adjustment base 424 slide downward on the side wall of the adjustment slot 421, thereby driving the suspension electromagnet 436 at the bottom of the rotating frame 431 to contact the metal barrel cover of the transfer barrel. At this time, since the suspension electromagnet 436 has magnetic force, the metal barrel cover can be tightly sucked. At this time, the user can control the adjustment motor 422 through the electrical control panel 101 to adjust the base 424 together with the adjustment slot 421. The rotating frame 431 moves upward by five centimeters. Since the metal barrel cover and the suspension electromagnet 436 are firmly attracted, the adjusting base 424 moves upward, which will drive the fixing rod 427 to move upward, and then the limiting rod 430 can slide downward relatively on the side wall of the fixing groove 428. At this time, the buffer spring 429 will be stretched and have a retracting elastic force. Then the user controls the rotating motor 433 to rotate through the electrical control panel 101, and the power gear 438 can drive the rotating gear 437 to rotate on the side wall of the rotating frame 431, thereby driving The rotating ring disk 439 rotates. Due to the inertial force of the rotating ring disk 439 and the friction between the suspended electromagnet 436 and the metal bottle cover, the rotating claw 434 can slide along the side wall of the opening groove 432 toward the rotating axis direction of the rotating gear 437 through the transmission of the connecting rod 435, until the side wall of the rotating claw 434 contacts the side wall of the metal bottle cover. At this time, the rotating motor 433 continues to work. Since the rotating claw 434 is limited by the metal barrel cover in the direction of the opening groove 432 and is in tight contact with the metal barrel cover, the rotating ring disk 439 will rotate and The rotating claw 434 is driven to rotate, and then the metal barrel cover is unscrewed. Since the buffer spring 429 is stretched, when the rotating ring disk 439 rotates, the rotating ring disk 439 will be driven to move upward, so that the metal barrel cover can be screwed out upward and separated from the transfer barrel. At this time, the user can control the folding hydraulic machine 426 to retract through the electrical control panel 101, thereby driving the folding bracket 425 to rotate on the side wall of the adjustment base 424, and then driving the rotating ring disk 439 and the metal barrel cover to move obliquely upward in the direction of the folding bracket 425 until they are separated from the top of the transfer barrel;

[0051] Then the user can control the extension of the telescopic hydraulic machine 211 through the electrical control panel 101, which can drive the rotating rod 213 to slide on the side wall of the fixed frame 212 until the bottom anti-overflow cylinder 217 contacts the mouth of the transfer barrel. Then the user can control the anti-overflow motor 214 to rotate through the electrical control panel 101, and the anti-overflow gear 215 and the anti-overflow gear 216 can drive the anti-overflow cylinder 217 to rotate on the side wall of the rotating rod 213, so that the inner side wall of the anti-overflow cylinder 217 can rotate on the outer wall of the mouth of the transfer barrel, so that the thread of the mouth of the transfer barrel is engaged with the thread of the inner wall of the anti-overflow cylinder 217, so that the anti-overflow cylinder 217 is screwed into the outer wall of the bottle mouth of the transfer barrel to close the transfer barrel. At this time, the liquid flowing into the transfer barrel can be prevented from evaporating and overflowing. Then the user can pump the liquid in the external storage tank into the feeding pipe 301, and the flow control valve 30 2. The electric-controlled three-way valve 226, the air inlet pipe 221 and the corrosion-resistant hose 223 finally enter the transfer barrel. The flow control valve 302 can monitor the liquid flow. At this time, the end of the electric-controlled three-way valve 226 connected to the nitrogen pipe 225 is closed, and the two ends connected to the feeding pipe 301 and the air inlet pipe 221 are opened. When the amount of liquid flowing through the feeding pipe 301 reaches a preset value, the flow control valve 302 will automatically close the feeding pipe 301, and at the same time, the end of the electric-controlled three-way valve 226 connected to the nitrogen pipe 225 will be opened. At this time, the high-pressure nitrogen in the nitrogen tank 224 will purge the air inlet pipe 221 and the corrosion-resistant hose 223 through the nitrogen pipe 225, and enter the transfer barrel, and start to purge the anti-overflow cylinder 217 and the toxic gas volatilized by the liquid inside the transfer barrel, and discharge it from the sealed box 1 through the sewage pipe 222 and enter the external waste gas treatment system;

[0052] The user can then control the anti-overflow motor 214 to reverse, and through the anti-overflow gear 215 and the anti-overflow gear 216, the anti-overflow cylinder 217 and the transfer barrel can rotate relative to each other and lose contact. At this time, the high-pressure nitrogen will begin to flush the entire sealed box body 1 and discharge the exhaust gas from the sewage pipe 222. The user can control the folding hydraulic press 426 to extend, and through the folding bracket 425, the rotating frame 431 and the metal barrel cover can return to the initial position, that is, just above the barrel mouth of the transfer barrel. Then the user can control the adjustment motor 422 to rotate through the electrical control panel 101, driving the adjustment base 424 and the rotating frame 431 to move downward to separate the metal barrel cover from the barrel mouth of the transfer barrel. Contact, and continue to move downward for five centimeters. Since the rotating frame 431 is limited by the transfer barrel, the buffer spring 429 will be compressed at this time, and then the user can control the rotating motor 433 to reverse, and the power gear 438, the rotating gear 437 and the connecting rod 435 are driven. Since the metal barrel cover and the rotating frame 431 are subject to the resistance of the metal barrel cover and the transfer barrel being tightened, the rotating claw can first move away from the rotating axis of the rotating gear 437 in the opening groove 432, and then move closer to the rotating axis of the rotating gear 437 after reaching the maximum displacement, thereby locking the metal barrel cover again and driving the metal barrel cover to reverse, that is, tightening the metal barrel cover to complete the sealing of the transfer barrel;

[0053] When the toxic gas inside the sealed box 1 is flushed, the user closes the electrically controlled three-way valve 226, retracts the clamping hydraulic press 412 and starts the sealing motor 505, so that the clamping block 413 can be out of contact with the transfer barrel. The forward rotation of the sealing motor 505 will drive the two sealing plates 503 to rotate relative to each other, thereby opening the sealing port 501. The user can then drag the transfer barrel out through the transport roller 411 and the sealing port 501, thereby completing the loading of the transfer barrel.
