When the hand-tightening bolt 107 is reset to its original position, the rectangular plate 202 is first removed, and then the prepared organic solvent receiving bottle is connected to the liquid outlet end of the gas-liquid separation tank 209, and then the controller 108 is used to start the motor 112.

When the temperature data received by the controller 108 is outside the pre-set temperature threshold range, the controller 108 will continue to start the two heaters 111. When the controller 108 receives When the received temperature data is within the pre-set temperature threshold range, the controller 108 will adjust the parameters of the two heaters 111 so that the cabinet 101 maintains the temperature for a period of time until the bonded NdFeB magnets complete the curing operation. When the temperature inside the cabinet 101 reaches a certain temperature, the bonded NdFeB magnets inside the cabinet 101 begin to solidify, and the organic solvent will also volatilize. When it is necessary to recover the organic solvent volatilized during the curing process of the bonded NdFeB magnets, the controller 108 is used to start the water pump 208.

At this time, the started air pump 203 will, with the cooperation of the two air pipes 204, the cabinet 101, the cabinet door 102, the annular groove 105, the sealing ring 106 and the sealing plate 214, enable the air inlet end of the shell 213 to obtain suction, and the air inlet end of the shell 213 that obtains suction will suck the air in the environment into the inside of the shell 213. Then, the air entering the shell 213 will be discharged in the two sets of slide grooves 215, the sealing ring 106 and the sealing plate 214. With the cooperation of the sealing plate 214 and the two filter plates 216, impurities mixed in the air are filtered out, and then the air that has completed the filtering operation will directly enter the interior of the cabinet 101. At the same time, the started air pump 203 will, with the cooperation of the two air pipes 204 and the cylindrical hole 205, extract the air inside the cabinet 101 and the organic solvent emitted during the solidification process of the bonded NdFeB magnets, and transport them to the interior of the condenser 206. The organic solvent that has entered the condenser 206 will be condensed into a liquid state with the cooperation of the started condenser 206 and the above-mentioned components. At the same time, the air inside the condenser 206 and the organic solvent that has been condensed into a liquid state will enter the gas-liquid separation with the cooperation of the connecting pipe 211. When the air in the condenser 206 and the condensed organic solvent enter the gas-liquid separation tank 209, the air entering the gas-liquid separation tank 209 will be transported from the gas outlet of the gas-liquid separation tank 209 to the inside of the cabinet 201 and then transported to the environment under the action of the activated gas-liquid separation tank 209, and the liquid organic solvent entering the gas-liquid separation tank 209 will enter the receiving bottle connected to it from the liquid outlet of the gas-liquid separation tank 209 under the cooperation of the activated gas-liquid separation tank 209. At the same time, the staff can observe the curing of the bonded NdFeB magnets inside the cabinet 101 with the cooperation of the T-shaped hole 103 and the transparent plate 104. When the curing operation of the NdFeB magnet is completed, and the condenser 206 and the gas-liquid separation tank 209 have completed their work, the two heaters 111, the temperature sensor 110, the air pump 203, the water pump 208, the condenser 206 and the gas-liquid separation tank 209 are turned off by the controller 108, and then the receiving bottle of the liquid organic solvent is removed and stored. Then, the above-mentioned operation steps are followed to open the cabinet door 102, and then the bonded NdFeB magnet that has completed the curing operation is taken out from the inside of the cabinet 101 and placed in a suitable position for cooling. When the temperature inside the cabinet 101 returns to room temperature, the device body 1 and the processing mechanism 2 are cleaned with the prepared tools, and then the components are reset to their original positions.

[0039] Among them, hinges are common parts in real life.

[0040] The rear surface of the cabinet door 102 is in contact with the front surface of the cabinet body 101 .

[0041] Among them, the gas-liquid separation tank 209 is composed of the following main components:

[0042] Tank body: This is the main part of the gas-liquid separation tank 209, and the material is selected according to the medium to be processed and the working conditions.

[0043] Air inlet end: The air inlet end is located on the side of the tank body and is used to introduce the fluid containing the gas-liquid mixture into the gas-liquid separation tank 209.

[0044] Gas outlet: The gas outlet is located on the side of the tank near the top and is used to discharge the separated gas.

[0045] Liquid outlet: The liquid outlet is at the bottom of the tank and is used to collect and discharge the separated liquid. The liquid outlet is usually equipped with a valve to control the discharge speed and flow of the liquid.

[0046] Baffle: The baffle is a common component inside the gas-liquid separation tank 209. It is installed inside the tank body and can change the flow direction of the fluid.

[0047] Wire mesh demister: The wire mesh demister is located at the upper part of the tank near the air outlet. It is composed of multiple layers of fine metal wire mesh or plastic wire mesh.

[0048] Liquid level meter: The liquid level meter is installed on the side of the tank and is used to monitor the liquid level in the tank in real time. The liquid level changes can be intuitively seen through the liquid level meter.

[0049] Working principle of gas-liquid separation tank 209: After the gas-liquid mixture enters the gas-liquid separation tank 209, due to the large difference in density between the liquid and the gas, under the action of gravity, the liquid naturally settles to the bottom of the tank body, while the gas floats upward. At the same time, the flow direction of the fluid is changed with the help of internal components, and the difference in inertia of the liquid and the gas is used to achieve separation. When the flow direction of the gas-liquid mixture changes suddenly, the liquid cannot change direction in time due to its large inertia, and will hit the baffle or the wall of the tank body, and then flow downward under the action of gravity. The gas has a small inertia and can more easily continue to flow upward as the flow direction changes, thereby achieving gas-liquid separation. In the process of gas flowing upward, the wire mesh demister plays a role. When tiny droplets pass through the wire mesh, they will collide with and adhere to the filaments of the wire mesh. After these droplets gather into larger droplets on the filaments, they flow downward along the wire mesh under the action of gravity and return to the liquid at the bottom of the tank body. In this way, the liquid entrained in the gas can be effectively removed, making the discharged gas purer.

[0050] Among them, the controller 108 (PLC controller), temperature sensor 110, heater 111, motor 112, air pump 203, condenser 206, water pump 208 and gas-liquid separation tank 209 are all existing technologies, and their working principles are all public technologies. Their models can be selected according to actual conditions and no excessive explanation will be given here.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
