Description

Technical Field

[0001] The invention relates to the technical field of hydrogenation reactors, in particular to a magnetic transmission hydrogenation reactor device. Background Art

[0002] A hydrogenation reactor is a device used to carry out chemical reactions under high pressure and high temperature conditions. It usually consists of a sealed container and a heating system and can be used for hydrogenation, hydrogenation or other gas phase reactions. Currently, hydrogenation reactors are widely used in petrochemicals, chemical synthesis, food processing and drug manufacturing.

[0003] In order to avoid excessive pressure inside the reactor, the hydrogenation reactors currently on the market are usually equipped with pressure relief devices, such as the patents: "Publication No. CN215087035U A hydrogenation reactor convenient for exhaust and pressure relief", "Publication No. CN219984649U A protective device for a hydrogenation reactor". Although these reactors can ensure a constant pressure inside the reactor, the discharged hydrogen will basically cool down. Once the staff transports the discharged hydrogen back to the reactor, the reaction rate of the materials in the reactor will inevitably fluctuate. At the same time, the existing pressure relief devices often cannot continue to work when encountering power outages and other accidents, which can easily cause accidents. Finally, the current hydrogenation reactors often use magnetic transmission mechanisms to avoid leakage, but after long-term use, the internal magnetic rotor of the magnetic transmission mechanism sometimes demagnetizes. When the staff encounters the above situation, they usually can only shut down the machine to repair the magnetic transmission mechanism. Summary of the invention

[0004] The purpose of the present invention is to provide a magnetic transmission hydrogenation reactor device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a magnetic transmission hydrogenation reactor device, the reactor device includes a shell, a transmission seat, a motor and an inner tank, the inner tank is arranged inside the shell, the transmission seat and the motor are arranged in sequence at the upper middle position of the inner tank, a fixed seat is arranged at the upper end of the inner tank, a transmission shaft is arranged at the inner middle position of the fixed seat, a magnetic coupler is arranged inside the transmission seat, the motor is connected to the transmission shaft through the magnetic coupler, the transmission shaft is connected to the stirring rod through a hollow coupling, and the present invention connects the motor through the magnetic coupler. The invention is connected with the stirring rod in a transmission manner, which can reduce the probability of hydrogen leakage, thereby improving the safety of the hydrogenation reaction. A temperature detector and a pressure detector are also arranged on the inner tank, and the temperature and pressure in the inner tank are monitored in real time by the temperature detector and the pressure detector. An air inlet pipe and a feed end are arranged on both sides of the transmission seat, and a first air duct, a second air duct and a protective mechanism are arranged inside the fixed seat. An annular seat is arranged at the lower end of the inner tank, and an air outlet cavity and an air storage cavity are arranged inside the annular seat. One end of the first air duct is connected to the air inlet pipe, and the other end of the first air duct is connected to the air outlet cavity. The lower part of the air outlet cavity is provided with an air outlet hole, one end of the second air channel is connected with the protective mechanism, the other end of the second air channel is connected with the air storage cavity, the feed end runs through the fixed seat, and a stirring rod is provided at the middle position inside the inner tank. When the present invention is working, the catalyst and materials are poured into the inner tank through the feed end, and hydrogen is transported into the inner tank through the air inlet pipe. The present invention is also provided with a protective mechanism. After the work is completed, the unreacted hydrogen in the inner tank can be stored through the protective mechanism for next use. During the working process, the protective mechanism can be adjusted in time. The hydrogen content in the inner tank is to transport excess hydrogen to the gas storage chamber to avoid excessive hydrogen transported into the inner tank per unit time, thereby preventing by-products from appearing in the material and also avoiding accidents caused by excessive pressure in the inner tank. When the hydrogen in the inner tank is no longer excessive, the hydrogen in the gas storage chamber can be returned to the inner tank through the protective mechanism. Compared with the pressure relief device currently used in the hydrogenation reactor device, the protective mechanism in the present invention does not change the temperature of the hydrogen when returning the hydrogen to the inner tank because the hydrogen is always in the inner tank, thereby avoiding fluctuations in the reaction rate of the material in the inner tank.

[0006] Furthermore, the stirring rod is a hollow structure, and a self-priming impeller is provided at the lower end of the stirring rod, and a paddle is provided at the middle position of the stirring rod. The material and hydrogen in the inner tank are stirred and mixed by the paddle, and the hydrogen floating above the material is re-absorbed into the reaction material through the self-priming impeller and the hollow coupling (the functions realized by the stirring rod, self-priming impeller, hollow coupling and paddle belong to conventional technical means in this field, and the specific structure is not described). There is a gap between the outer shell and the inner tank, and a heating element can be provided in the gap to facilitate heating of the material in the inner tank during operation. The lower end of the outer shell is provided with a liquid inlet, and the upper end of the outer shell is provided with a liquid outlet. After the work is completed, the material in the inner tank can be cooled by transporting coolant into the gap.

[0007] Furthermore, the protection mechanism includes a motor, a reversing groove, a crankshaft, a connecting seat and a protective cavity, the crankshaft is arranged above the protective cavity, a piston is arranged in the protective cavity, the crankshaft is connected to the piston through a connecting rod, the crankshaft is connected to the transmission shaft through a connecting seat and a first bevel gear assembly, an electromagnet is arranged at a position of the crankshaft near the connecting seat, and one end of the connecting seat near the electromagnet is magnetic, a first through hole, a second through hole and a third through hole are arranged at the side end of the reversing groove, the first through hole is connected to the second air duct, the second through hole is connected to the inner tank, and the third through hole is connected to the protective cavity, a reversing assembly is also arranged in the reversing groove, the reversing assembly includes an air inlet frame, a first sealing block, a second sealing block and an air outlet frame, the air inlet frame and the air outlet frame are relatively arranged on both sides of the reversing shaft through two support rods, the first sealing block is arranged in the air inlet frame through a first sealing spring, the second sealing block is arranged in the air outlet frame through a second sealing spring, The motor is connected to the reversing shaft. During normal working of the present invention, the electromagnet is in a non-working state, and the crankshaft does not rotate when the transmission shaft rotates. When too much hydrogen is delivered to the inner tank per unit time during working, or when the unreacted hydrogen in the inner tank needs to be stored after the work is finished, the staff can first turn on the motor to align the air inlet frame with the second through hole and the air outlet frame with the first through hole, and then turn on the electromagnet. The transmission shaft rotates with the crankshaft synchronously through the electromagnet and the connecting seat, and the piston is driven to move up and down in the protective cavity through the crankshaft. At this time, the hydrogen in the inner tank will flow into the gas storage cavity unidirectionally and continuously, and the hydrogen is stored through the gas storage cavity; when the staff needs to return the hydrogen in the gas storage cavity to the inner tank, the staff only needs to change the direction of the air inlet frame and the air outlet frame through the motor (the air outlet frame is aligned with the second through hole, and the air inlet frame is aligned with the first through hole), so that the hydrogen in the gas storage cavity can flow into the inner tank unidirectionally and continuously.

[0008] Furthermore, the protection mechanism also includes a crank handle, which is arranged above the fixed seat, and the crank handle is connected to the end of the crankshaft away from the transmission shaft through the second bevel gear assembly. When the protection mechanism in the present invention is not working, the air inlet frame is always aligned with the second through hole, and the air outlet frame is aligned with the first through hole (the protection mechanism needs to be reset after the work is completed). When encountering power outages, equipment failures and other phenomena, the staff usually need to remove the material from the inner tank. When encountering the above situation, the present invention can rotate the crankshaft by rotating the crank handle. At this time, the protection mechanism can continue to work, thereby transporting the hydrogen in the inner tank to the gas storage chamber, thereby avoiding the hydrogen in the inner tank from being retained above the material, and preventing the staff from leaking the hydrogen in the inner tank into the external environment during the process of discharging the material.

[0009] Furthermore, a brake assembly is provided at one end of the fixed seat close to the transmission seat, and the brake assembly includes a brake groove, a telescopic groove, a hydraulic element and an annular groove. A brake disc is provided in the brake groove, and the brake disc is fixedly installed on the outside of the transmission shaft. When the present invention is working, the brake disc and the transmission shaft rotate synchronously, and a block is provided at one end of the brake disc close to the telescopic groove. A brake frame is provided in the telescopic groove, and the brake frame is connected to the telescopic groove through a telescopic spring rod, and the annular groove is connected to the end of the telescopic groove away from the brake groove, and the annular groove is connected to the hydraulic element. When the present invention encounters a situation where emergency braking is required, transmission fluid is transported to the telescopic groove through the hydraulic element. At this time, under the action of the hydraulic pressure, the brake frame will extend out of the telescopic groove, and the transmission shaft and the stirring rod can be stopped from rotating urgently through the brake frame and the block.

[0010] Furthermore, a groove is provided at the middle position of the block, a sensing hole is provided at the middle position of the brake frame, a sensing block is provided at one end of the sensing hole close to the brake disc, a piezoelectric sheet is provided at one end of the sensing hole away from the brake disc, and a sensing spring is provided between the sensing block and the piezoelectric sheet. The present invention monitors the rotation of the transmission shaft through the sensing block and the piezoelectric sheet. If the transmission shaft rotates smoothly, the piezoelectric sheet will output a relatively stable electrical signal. When the transmission shaft rotates unsteadily, the brake disc will intermittently apply a force to the sensing block. At this time, under the action of the sensing spring, the piezoelectric sheet will output an electrical signal with large fluctuations. The staff can determine whether the rotation of the transmission shaft is smooth by monitoring the fluctuation amplitude of the electrical signal generated by the piezoelectric sheet, so as to timely repair the various transmission components of the present invention.

[0011] Furthermore, a transmission cavity is provided inside the transmission seat, and the magnetic coupler is arranged in the transmission cavity. The magnetic coupler includes a linkage disk, an outer magnetic rotor, an inner magnetic rotor and an isolation sleeve. The inner magnetic rotor is arranged inside the isolation sleeve, and the outer magnetic rotor is arranged outside the isolation sleeve. The transmission shaft is fixedly connected to the inner magnetic rotor, and the motor is transmission-connected to the outer magnetic rotor through the motor shaft and the linkage disk. When the motor in the present invention rotates with the outer magnetic rotor, the inner magnetic rotor will rotate synchronously. At this time, the transmission shaft will drive the stirring rod to stir the material in the inner tank, and the probability of hydrogen leakage is reduced by the magnetic coupler.

[0012] Furthermore, a liquid guide groove is arranged above the transmission cavity, a slider and transmission fluid are arranged at the lower end of the interior of the transmission cavity, a liquid pump is arranged outside the transmission seat, the liquid pump has forward and reverse functions, one end of the liquid pump is connected with the liquid guide groove, and the other end of the liquid pump is connected with the lower end of the interior of the transmission cavity, and the transmission fluid content inside the liquid guide groove and the transmission fluid content at the lower end of the interior of the transmission cavity are controlled by the liquid pump, a slide groove is arranged on the outer surface of the motor shaft, and the linkage disk can perform lifting and lowering movements on the motor shaft, and two groups of external magnetic rotors are arranged, and the two groups of external magnetic rotors are arranged in sequence below the linkage disk. Since the liquid is incompressible, the present invention is achieved by The liquid pump changes the transmission fluid content inside the liquid guide groove and the transmission fluid content at the lower end of the transmission cavity, so that the linkage disk can move up and down in the transmission cavity. During normal working of the present invention, a group of outer magnetic rotors away from the linkage disk are aligned with the inner magnetic rotor. When a group of outer magnetic rotors away from the linkage disk suddenly loses magnetism during working, the staff can drive the linkage disk to descend through the liquid pump. At this time, a group of outer magnetic rotors close to the linkage disk are aligned with the inner magnetic rotor, so as to ensure the normal operation of the transmission shaft and the stirring rod. Compared with the current hydrogenation reactor device, the present invention can replace the outer magnetic rotor without stopping the machine when the outer magnetic rotor demagnetizes, so as to prevent the hydrogenation reaction of the material from being affected.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: compared with the current hydrogenation reactor device, the present invention is provided with a protection mechanism. After the work is completed, the unreacted hydrogen in the inner tank can be stored through the protection mechanism for next use. During the working process, the hydrogen content in the inner tank can be adjusted in time through the protection mechanism, and the excess hydrogen can be transported to the gas storage chamber to avoid excessive hydrogen transported to the inner tank per unit time. When the hydrogen in the inner tank is no longer excessive, the hydrogen in the gas storage chamber can be returned to the inner tank through the protection mechanism. Compared with the pressure relief device used in the current hydrogenation reactor device, the protection mechanism in the present invention, on the one hand, when the hydrogen is returned to the inner tank, since the hydrogen is always in the inner tank, the temperature of the hydrogen will not change, thereby avoiding fluctuations in the reaction rate of the material in the inner tank. On the other hand, the protection mechanism can continue to work under power failure and the like, thereby improving safety. The invention also provides a brake assembly, which can stop the transmission shaft and the stirring rod from rotating urgently on the one hand, and can monitor the rotation of the transmission shaft in real time on the other hand, so as to facilitate the staff to judge the wear conditions of various transmission parts of the invention. The invention also provides two groups of external magnetic rotors, and controls the transmission fluid content inside the liquid guide groove and the transmission fluid content at the lower end of the transmission cavity by a liquid pump, so as to change the positions of the two groups of external magnetic rotors. During normal operation of the invention, a group of external magnetic rotors away from the linkage disk are aligned with the inner magnetic rotor. When a group of external magnetic rotors away from the linkage disk suddenly loses magnetism, the staff can use the liquid pump to align a group of external magnetic rotors close to the linkage disk with the inner magnetic rotor, so as to ensure the normal operation of the transmission shaft and the stirring rod. Compared with the current hydrogenation reactor device, the invention can replace the external magnetic rotor without stopping the machine when encountering the demagnetization phenomenon of the external magnetic rotor, so as to prevent the hydrogenation reaction of the material from being affected.

The feed end 5 runs through the fixed seat 6, and a stirring rod 72 is provided at the middle position of the inner tank 7. When the present invention is working, the catalyst and materials are poured into the inner tank 7 through the feed end 5, and hydrogen is transported into the inner tank 7 through the air inlet pipe 2. The present invention is also provided with a protective mechanism. After the work is completed, the unreacted hydrogen in the inner tank 7 can be stored through the protective mechanism for next use. During the working process, the inner tank 7 can be adjusted in time through the protective mechanism. The hydrogen content in the inner liner 7 is adjusted, and the excess hydrogen is transported to the gas storage chamber 712 to avoid excessive hydrogen transported to the inner liner 7 per unit time, thereby preventing by-products from appearing in the material and avoiding accidents caused by excessive pressure in the inner liner 7. When the hydrogen in the inner liner 7 is no longer excessive, the hydrogen in the gas storage chamber 712 can be returned to the inner liner 7 through the protective mechanism. Compared with the pressure relief device currently used in the hydrogenation reactor device, the protective mechanism in the present invention does not change the temperature of the hydrogen when returning the hydrogen to the inner liner 7 because the hydrogen is always in the inner liner 7, thereby avoiding fluctuations in the reaction rate of the material in the inner liner 7.

[0031] like Figure 2-Figure 4As shown, the stirring rod 72 is a hollow structure, a self-priming impeller is provided at the lower end of the stirring rod 72, and a paddle is provided at the middle position of the stirring rod 72. The material and hydrogen in the inner tank 7 are stirred and mixed by the paddle, and the hydrogen floating above the material is re-absorbed into the reaction material through the self-priming impeller and the hollow coupling 721 (the functions realized by the stirring rod 72, the self-priming impeller, the hollow coupling 721 and the paddle belong to conventional technical means in this field, and the specific structure is not described). There is a gap between the outer shell 1 and the inner tank 7, and a heating element can be provided in the gap to facilitate heating of the material in the inner tank 7 during operation. The lower end of the outer shell 1 is provided with a liquid inlet, and the upper end of the outer shell 1 is provided with a liquid outlet. After the work is completed, the material in the inner tank 7 can be cooled by conveying coolant into the gap.

[0032] like Figure 4-Figure 9As shown, the protection mechanism includes a motor, a reversing groove 66, a crankshaft 67, a connecting seat 68 and a protection chamber 69. The crankshaft 67 is arranged above the protection chamber 69. A piston is arranged in the protection chamber 69. The crankshaft 67 is connected to the piston through a connecting rod. The crankshaft 67 is connected to the transmission shaft 62 through the connecting seat 68 and the first bevel gear assembly. An electromagnet 671 is arranged at a position of the crankshaft 67 near the connecting seat 68. One end of the connecting seat 68 near the electromagnet 671 is magnetic. The side end of the reversing groove 66 is provided with a first through hole, a second through hole and a third through hole. The first through hole is connected to the The second air channel 65 is connected, the second through hole is connected to the inner tank 7, the third through hole is connected to the protective cavity 69, and a reversing assembly is also arranged in the reversing groove 66, and the reversing assembly includes an air inlet frame 661, a first sealing block 662, a second sealing block 663 and an air outlet frame 664. The air inlet frame 661 and the air outlet frame 664 are relatively arranged on both sides of the reversing shaft 665 through two support rods. The first sealing block 662 is arranged in the air inlet frame 661 through a first sealing spring, and the second sealing block 663 is arranged in the air outlet frame 664 through a second sealing spring. The motor is connected to the reversing shaft 665. 65 is connected. In the normal working process of the present invention, the electromagnet 671 is in a non-working state. When the transmission shaft 62 rotates, the crankshaft 67 does not rotate. When too much hydrogen is delivered to the inner tank 7 per unit time during the working process, or when the unreacted hydrogen in the inner tank 7 needs to be stored after the work is finished, the staff can first turn on the motor to align the air inlet frame 661 with the second through hole and the air outlet frame 664 with the first through hole, and then turn on the electromagnet 671. Through the electromagnet 671 and the connecting seat 68, the transmission shaft 62 rotates with the crankshaft 67 rotates synchronously, and the piston is driven by the crankshaft 67 to move up and down in the protective cavity 69. At this time, the hydrogen in the inner tank 7 will flow into the gas storage cavity 712 in a unidirectional manner, and the hydrogen will be stored in the gas storage cavity 712. When the staff needs to return the hydrogen in the gas storage cavity 712 to the inner tank 7, the staff only needs to change the direction of the air inlet frame 661 and the air outlet frame 664 through the motor (the air outlet frame 664 is aligned with the second through hole, and the air inlet frame 661 is aligned with the first through hole), so that the hydrogen in the gas storage cavity 712 can flow into the inner tank 7 in a unidirectional manner.

[0033] like Figure 3-Figure 6As shown, the protection mechanism also includes a crank handle 61, which is arranged above the fixed seat 6, and the crank handle 61 is connected to the end of the crankshaft 67 away from the transmission shaft 62 through the second bevel gear assembly. When the protection mechanism in the present invention is not working, the air inlet frame 661 is always aligned with the second through hole, and the air outlet frame 664 is aligned with the first through hole (the protection mechanism needs to be reset after the work is completed). When encountering power outages, equipment failures and other phenomena, the staff usually need to remove the material from the inner liner 7. When encountering the above situation, the present invention can rotate the crankshaft 67 by rotating the crank handle 61. At this time, the protection mechanism can continue to work, thereby transporting the hydrogen in the inner liner 7 to the gas storage chamber 712, thereby avoiding the hydrogen in the inner liner 7 from being retained above the material, and preventing the staff from leaking the hydrogen in the inner liner 7 into the external environment during the process of discharging the material.

[0034] like Figure 10-12 As shown, a brake assembly 63 is provided at one end of the fixed seat 6 close to the transmission seat 3. The brake assembly 63 includes a brake groove, a telescopic groove, a hydraulic element and an annular groove 634. A brake disc 631 is provided in the brake groove. The brake disc 631 is fixedly installed on the outer side of the transmission shaft 62. When the present invention is working, the brake disc 631 and the transmission shaft 62 rotate synchronously, and a stopper 6311 is provided at one end of the brake disc 631 close to the telescopic groove. A brake frame 633 is provided in the telescopic groove. The brake frame 633 is connected to the telescopic groove through a telescopic spring rod, and the annular groove 634 is connected to the end of the telescopic groove away from the brake groove. The annular groove 634 is connected to the hydraulic element (the hydraulic element is not drawn in the figure). When the present invention encounters a situation where emergency braking is required, the transmission fluid is transported into the telescopic groove through the hydraulic element. At this time, under the action of the hydraulic pressure, the brake frame 633 will extend out of the telescopic groove, and the transmission shaft 62 and the stirring rod 72 can be stopped from rotating urgently through the brake frame 633 and the stopper 6311.

[0035] like Figure 10-12 As shown, a groove is provided at the middle position of the block 6311, a sensing hole is provided at the middle position of the brake frame 633, a sensing block 632 is provided at one end of the sensing hole close to the brake disc 631, a piezoelectric sheet is provided at one end of the sensing hole away from the brake disc 631, and a sensing spring is provided between the sensing block 632 and the piezoelectric sheet. The present invention monitors the rotation of the transmission shaft 62 through the sensing block 632 and the piezoelectric sheet. If the transmission shaft 62 rotates smoothly, the piezoelectric sheet will output a relatively stable electrical signal. When the transmission shaft 62 rotates unsteadily, the brake disc 631 will intermittently apply a force to the sensing block 632. At this time, under the action of the sensing spring, the piezoelectric sheet will output an electrical signal with a large fluctuation. The staff can determine whether the rotation of the transmission shaft 62 is stable by monitoring the fluctuation amplitude of the electrical signal generated by the piezoelectric sheet, so as to timely repair the various transmission components of the present invention.

[0036] like Figure 2 , Fig.13 As shown, a transmission cavity is provided inside the transmission seat 3, and a magnetic coupler is arranged in the transmission cavity. The magnetic coupler includes a linkage disk 411, an outer magnetic rotor 32, an inner magnetic rotor 34 and an isolation sleeve 35. The inner magnetic rotor 34 is arranged inside the isolation sleeve 35, and the outer magnetic rotor 32 is arranged outside the isolation sleeve 35. The transmission shaft 62 is fixedly connected to the inner magnetic rotor 34, and the motor 4 is transmission-connected to the outer magnetic rotor 32 through the motor shaft 41 and the linkage disk 411. When the motor 4 in the present invention rotates with the outer magnetic rotor 32, the inner magnetic rotor 34 will rotate synchronously. At this time, the transmission shaft 62 will drive the stirring rod 72 to stir the material in the inner tank 7, and the probability of hydrogen leakage is reduced by the magnetic coupling.

[0037] like Figure 2 , Fig.13 As shown, a liquid guide groove is arranged above the transmission cavity, a slider 33 and a transmission fluid are arranged at the lower end of the interior of the transmission cavity, a liquid pump 31 is arranged outside the transmission seat 3, and the liquid pump 31 has a forward and reverse rotation function. One end of the liquid pump 31 is connected to the liquid guide groove, and the other end of the liquid pump 31 is connected to the lower end of the interior of the transmission cavity. The transmission fluid content inside the liquid guide groove and the transmission fluid content at the lower end of the interior of the transmission cavity are controlled by the liquid pump 31. A slide groove is arranged on the outer surface of the motor shaft 41, and the linkage disk 411 can perform lifting and lowering movements on the motor shaft 41. Two groups of external magnetic rotors 32 are arranged, and the two groups of external magnetic rotors 32 are arranged in sequence below the linkage disk 411. Since the liquid is incompressible, the present invention changes the transmission fluid content inside the liquid guide groove through the liquid pump 31. , the transmission fluid content at the lower end of the transmission cavity can make the linkage disk 411 move up and down in the transmission cavity. During normal working of the present invention, a group of outer magnetic rotors 32 away from the linkage disk 411 are aligned with the inner magnetic rotor 34. When a group of outer magnetic rotors 32 away from the linkage disk 411 suddenly loses its magnetism during working, the staff can drive the linkage disk 411 to descend through the liquid pump 31. At this time, a group of outer magnetic rotors 32 close to the linkage disk 411 are aligned with the inner magnetic rotor 34, so as to ensure the normal operation of the transmission shaft 62 and the stirring rod 72. Compared with the current hydrogenation reactor device, the present invention can replace the outer magnetic rotor 32 without stopping the machine when the outer magnetic rotor 32 demagnetizes, so as to prevent the hydrogenation reaction of the material from being affected.

[0038] The working principle of the present invention is as follows: the catalyst and materials are poured into the inner tank 7 through the feed end 5, hydrogen is transported into the inner tank 7 through the air inlet pipe 2, the motor 4 is turned on during operation, the outer magnetic rotor 32 is rotated by the motor 4, the inner magnetic rotor 34 and the transmission shaft 62 rotate synchronously at this time, the stirring rod 72 is rotated through the transmission shaft 62, the stirring rod 72 is a hollow structure, the materials and hydrogen in the inner tank 7 are stirred and mixed by the blades on the stirring rod 72, the hydrogen floating on the materials is re-absorbed into the reaction materials by the self-priming impeller on the stirring rod 72 and the hollow coupling 721, so as to avoid the waste of hydrogen. During the operation, if too much hydrogen is transported into the inner tank 7 per unit time, the protective mechanism can be used to suck the hydrogen in the inner tank 7. Part of the hydrogen is transported to the gas storage chamber 712, on the one hand to avoid the appearance of by-products in the material, and on the other hand to prevent accidents caused by excessive pressure in the inner tank 7. When the hydrogen in the inner tank 7 is no longer excessive, the hydrogen in the gas storage chamber 712 can be returned to the inner tank 7 through the protective mechanism. When a group of outer magnetic rotors 32 away from the linkage disk 411 suddenly loses its magnetism during operation, the staff can drive the linkage disk 411 to descend through the liquid pump 31. At this time, a group of outer magnetic rotors 32 close to the linkage disk 411 are aligned with the inner magnetic rotor 34 to ensure the normal operation of the transmission shaft 62 and the stirring rod 72. After the work is completed, the unreacted hydrogen in the inner tank 7 is stored through the protective mechanism for next use.

A person skilled in the art may change, modify, substitute and vary the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
