The bottom of the movable kettle bottom 110 is provided with the blast pipe 130, the blast pipe 130 is used for discharging the inside air of reation kettle 100, the interior space of blast pipe 130 is divided into second cavity and third cavity by baffle 140, the second cavity can communicate with reation kettle 100 inside, the third cavity intussuseption is filled with hydraulic oil, baffle 140 is located one side elastic connection in the second cavity has regulating plate 150, concretely speaking, through first spring 152 elastic connection between regulating plate 150 and the baffle 140, first connecting port 151 has been seted up on it to the regulating plate 150 along vertical direction extension, second connecting port 131 has been seted up on the upper portion of blast pipe 130, regulating plate 150 can slide along vertical direction, and then change the overlapping area of first connecting port 151 and second connecting port 131, when regulating plate 150 vertically upwards slides to upper limit position, the overlapping area of second connecting port 131 and first connecting port 151 is the biggest, the speed of outwards discharging of gas in the reation kettle 100 can be faster, when regulating plate 150 vertically downwards slides to lower limit position, second connecting port 131 and first connecting port 131 do not overlap and can not discharge gas to outside the reation kettle 100.
The adjusting plate 150 is further connected with an air bag 160, the gas density in the air bag 160 is smaller than the gas density in the second chamber, and the difference value between the gas density in the air bag 160 and the gas density in the second chamber is positively correlated with the superposition area of the first communication port 151 and the second communication port 131.
The third communication port 132 is opened at the lower portion of the exhaust pipe 130, the third chamber is communicated with the first chamber through the third communication port 132, specifically, a connection pipe orifice 1211 is provided at the upper portion of the piston pipe 121, the third communication port 132 and the connection pipe orifice 1211 are connected through a flexible hydraulic oil pipe, specifically, one end of the flexible hydraulic oil pipe is inserted into the connection pipe orifice 1211, and then the other end of the flexible hydraulic oil pipe is inserted into the third communication port 132, so that the first chamber and the third chamber are mutually communicated.

It should be further added that, in order to make the overlapping area of the first communication port 151 and the second communication port 131 be the largest, the adjusting plate 150 is just at the upper limit position, and a limit groove needs to be further formed on the inner wall of the exhaust pipe 130, so that when the engaging plate 174 moves vertically upward along the limit groove to the point that the engaging plate 174 contacts with the upper end surface of the limit groove, the adjusting plate 150 is at the upper limit position, and the overlapping area of the first communication port 151 and the second communication port 131 is the largest.
When the reaction kettle 100 is not in use, the second communication port 131 is communicated with the second chamber and the inside of the reaction kettle 100, the gas in the reaction kettle 100 is air, and because the gas density in the air bag 160 is smaller than the air density, the air bag 160 drives the adjusting plate 150 to vertically move upwards under the buoyancy effect, so that the adjusting plate 150 moves to an upper limit position, at this time, the first spring 152 is vertically pulled upwards and stretched to a longest state, and at this time, the overlapping area of the second communication port 131 and the first communication port 151 is at a maximum value. In the production preparation stage, the staff needs to empty the air in the reaction kettle 100, so that the air in the reaction kettle 100 is pushed to move downwards by utilizing the physical property that the density of the hydrogen is smaller than that of the air, so that the air in the reaction kettle 100 firstly enters the second cavity and then is discharged outwards through the first communication port 151 and the second communication port 131, the air entering the second cavity starts to be mixed gas of the air and the hydrogen as the hydrogen is continuously injected into the reaction kettle 100, the density of the mixed gas is smaller than that of the air, the buoyancy effect of the air bag 160 is gradually reduced, the regulating plate 150 gradually moves downwards under the action of the elastic force of the first spring 152, at the moment, the superposition area of the second communication port 131 and the first communication port 151 starts to be reduced, the gas density around the air bag 160 is further reduced along with the increase of the content of the hydrogen in the mixed gas, the superposition area of the second communication port 131 and the first communication port 151 is further reduced, and the flow of the gas discharged outwards from the second communication port 131 is further reduced gradually, and the loss of the hydrogen is reduced gradually; when the air in the reaction kettle 100 is completely discharged, the air in the second cavity is hydrogen, the difference between the density of the air inside and outside the air bag 160 is the smallest, the buoyancy acting force borne by the air bag 160 is the smallest, at this time, under the elastic action of the first spring 152, the first spring 152 pulls the adjusting plate 150 and the air bag 160 to vertically move downwards, so that the adjusting plate 150 moves downwards to the lower limit position, at this time, the second communication port 131 and the first communication port 151 are not overlapped, and the hydrogen in the second cavity can not be discharged outwards through the first communication port 151 and the second communication port 131, so that the hydrogen in the reaction kettle 100 is prevented from being discharged outwards in time after the air in the reaction kettle 100 is completely discharged, and the waste of the hydrogen is avoided; while hydrogen is continuously injected into the reaction kettle 100, the pressure of the gas on the bottom 110 of the movable kettle is gradually increased, so that the bottom 110 of the movable kettle overcomes the elasticity of the spring and then moves vertically downwards, at the moment, the piston tube 121 moves downwards along with the bottom 110 of the movable kettle, the volume of the first chamber is increased, hydraulic oil in the third chamber enters the first chamber through the third communication port 132, the partition plate 140 is stressed to move downwards, and the first spring 152 is connected to the partition plate 140, so that the first spring 152 is also subjected to vertical downward pulling force, after the mixed gas in the interface area of the air and the hydrogen enters the second chamber, even if all the gas entering the second chamber at a certain moment is air, the regulating plate 150 does not move upwards instantaneously in the vertical direction, so that the situation that the loss amount of the hydrogen is increased due to the fact that the overlapping area of the second communication port 131 and the first communication port 151 is increased instantaneously at the moment is avoided when the air is about to be completely discharged is avoided, and the loss amount of the hydrogen can be further reduced.
It will be appreciated that in the interface region of hydrogen and air, the hydrogen and air are in a disordered mixed state, and that there are localized regions of all air, localized regions of all hydrogen, and more localized regions of mixed gas of hydrogen and air.
It is also added that in order to equalize the pressures applied to the upper and lower sides of the connector plate 174, a vent hole should be provided in the connector plate 174.

It will be appreciated that, to make the second communication port 131 in the state of being alternately opened or closed, because the air flow rate near the second communication port 131 is fast, and the air flow rate between the connection plate 174 and the partition plate 140 is slow, and the pressure is small where the flow rate is large, the air bag 160 will move vertically downward under the effect of the pressure difference, so by making the second communication port 131 in the state of being alternately opened or closed, the gas in the second chamber can be periodically kept still, avoiding inaccurate movement timing of the adjustment plate 150 due to the effect of the gas pressure difference, and making the adjustment plate 150 unable to make the second communication port 131 and the first communication port 151 in a non-overlapping state in time after the hydrogen is completely discharged.
