Meanwhile, when the gaseous metal always directly condenses on a condensing surface, the condensing efficiency of the condensing surface is reduced along with the continuous increase of the gaseous metal for a long time, so that the condensing effect is reduced, the hinge body 8 is arranged, the air outlet 9 has mobility, when the rotating shaft lever 2 rotates, the air outlet 9 rotates along with the rotating shaft lever 2, and the air outlet 9 is further acted by centrifugal force, so that when the rotating shaft lever 2 changes speed, the air outlet 9 also changes along with the speed change, namely, when the rotating shaft lever 2 is at a low speed, the air outlet 9 is subjected to smaller centrifugal force, the air outlet 9 is downwards deflected due to self gravity and is in a downwards inclined state, so that the gaseous metal flows downwards through the air outlet 9, and when the rotating shaft lever 2 changes speed at a low speed and a high speed, the air outlet 9 is influenced by the change of the centrifugal force, the flow direction of the gaseous metal can be changed along with the change of the air outlet 9 until the level is reached, so that the gaseous metal can continuously flow to different areas on the surface of the condensation piece 10, and further when one condensation surface is condensed and loses low temperature, the gaseous metal can be timely converted to the low-temperature condensation surface which is not condensed on the other surface to perform complete condensation, thereby avoiding the fixation of the output end of the existing gaseous metal and the condensation surface of the condensation piece 10, further leading the gaseous metal to be always contacted with the same condensation surface, leading the condensation surface to be unable to quickly recover the low-temperature state after condensing the gaseous metal which flows, further performing complete condensation on the uncondensed gaseous metal which flows later, thereby causing the problem of low condensation efficiency, effectively improving the condensation efficiency, the surface of the condensing part 10 is fully used, the circulating energy consumption of condensation is reduced, and the condensing effect is enhanced.
The working principle of the using method of the invention is as follows:
when the purification and distillation of the rare earth solution are needed, the existing servo motor is started firstly, the rotating shaft rod 2 starts to rotate, meanwhile, the condensing part 10 is started, pre-cooling is started, the heating body 1 is started to preheat, wherein the heat temperature generated by the heating body 1 can be sequentially transferred to the evaporation tray 3 and the fixed slope body 4, after the pre-rotation, pre-cooling and preheating preparation in the device are completed, the rare earth solution is continuously poured into the evaporation tray 3 through the feeding port 12 by the existing material conveying device, when the solution flows into the inner cavity of the first layer evaporation tray 3, a part of the solution flows to the surface of the fixed slope body 4 and flows downwards along the surface of the fixed slope body 4, then the other part of the solution is accumulated between the fixed slope body 4 and the rotating shaft rod 2, the other part of the solution flows downwards through the fluid passage 5 and flows into the inner cavity of the second layer evaporation tray 3, a certain amount of solution is reserved in the inner cavity of the second layer evaporation tray 3 when the solution passes through the fluid passage 5, when the solution flows into the inner cavity of the first layer evaporation tray 3, a part of the solution flows downwards through the control system is continuously circulated from top to the top end of the existing servo motor, the solution is continuously circulated to the top end of the first layer evaporation tray 3, and finally, the solution flows downwards to the top end of the inner cavity of the first layer evaporation tray 3 is continuously and the inner cavity is continuously circulated, the solution is circulated to the inner cavity of the second layer 3 due to the inner cavity of the fluid layer 3, and the solution is continuously circulated through the inner cavity of the layer through the layer of the fluid layer through the fluid passage 3, the servo motor starts to perform variable speed motion, namely, the servo motor is uniformly changed from a certain low speed value to a certain high speed value, and is reversely and uniformly changed to an initial low speed value from the high speed value.
When the servo motor changes speed, the rotating shaft lever 2 changes along with the servo motor, when the rotating shaft lever 2 starts to accelerate from an initial low speed value and changes to a high speed value, the centrifugal force born by the solution gradually increases along with the speed change of the rotating shaft lever 2, when the centrifugal force increases, the solution is out of balance and is in a static state and is thrown outwards, but is uniformly changed in speed due to the centrifugal force, so that the solution gradually extends and spreads on the surface of the fixed slope body 4 and continuously flows upwards when the solution moves outwards under the action of the centrifugal force, and the thickness of the accumulated solution gradually weakens when the solution extends upwards and flows, so that when the solution flows and is transferred on the surface of the fixed slope body 4, the thickness of the solution is in a continuously thinned state, and when the solution covers the surface of the fixed slope body 4, the heat energy contained in the fixed slope body 4 rapidly boils and evaporates the thin layer of the solution, so that the solution becomes into a gas state.
When the rotating shaft lever 2 is changed to a set proper high-speed value, the control system of the existing servo motor is used for controlling the existing servo motor to change the speed again, the speed of the servo motor is changed from the high-speed value back to the initial low-speed value again, the speed change process is uniformly changed, and the same principle as the motion process is adopted, when the rotating shaft lever 2 is used for reducing the speed, the centrifugal force born by the solution is reduced, the solution flowing to the high position of the fixed slope body 4 can reversely flow back to the low position of the fixed slope body 4 along the surface of the fixed slope body 4 again, when the solution reversely flows back, the solution can flow back to the surface of the fixed slope body 4 again, and then the fixed slope body 4 rapidly distills the solution again, so that the solution is rapidly changed into a gas state.
Meanwhile, when the solution is evaporated to generate gaseous metal, the gaseous metal flows into the inner cavity of the air outlet pipe 6 through the molecular film 7, flows to the surface of the condensation piece 10 through the air outlet 9, condenses the gaseous metal through the condensation piece 10, and the condensed and liquefied rare earth flows downwards along the surface of the condensation piece 10 and flows into the existing collecting device, so that the distillation and purification of the rare earth metal elements are completed.
