Use the utility model discloses a device's specific embodiment as follows: the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can better understand the present invention and apply it to experimental work, but the examples are not intended to limit the present invention.
The sealing assembly of the pressure reactor vessel is assembled completely according to fig. 1, wherein the spring force of the pressure spring is prefabricated. The elastic force is mainly adjusted according to the tolerance limit of the pressure reaction tank. The greater the spring force, the higher the tolerance limit of the pressure reactor. If the sealing device is used for vacuum acid-dispelling operation, a small elastic spring needs to be replaced, and sealing in a vacuum environment is mainly ensured.
In the using process, the sealing component of the pressure reaction tank is firstly pressed on the upper part of the reaction tank body 2, and the reaction tank sealing cover 1 is twisted with the reaction tank body 2 through threads. In the twisting process, the reaction tank sealing gasket 3 with the gas circuit seals the whole reaction tank body 2 with the inner wall of the reaction tank body 2.
After the pressure is generated by the reaction, the gas in the reaction tank body 2 expands to push the reaction tank sealing gasket 3 with the gas path to move upwards, and meanwhile, the pressure spring 6 in the reaction tank sealing interlayer 4 also starts to generate a downward resistance. When the resistance generated by the spring is not large than the pressure in the tank, the sealing gasket 3 of the reaction tank with the gas circuit continues to move upwards.
When the pressure in the reaction tank body 2 is enough, the reaction tank sealing gasket 3 with the gas path moves to a proper position, and the exhaust hole of the reaction tank sealing gasket 3 with the gas path is flush with the exhaust hole on the reaction tank sealing interlayer 4 to form the through of the gas path, so that the gas in the reaction tank can be exhausted along the path. After the gas is discharged, the pressure inside the reaction tank 2 is reduced, so that the reaction tank sealing gasket 3 with the gas path moves down first under the resistance of the pressure spring, and the communicated vent hole passage is blocked again.
In the whole process of the pressurized reaction, the overpressure gas in the reaction tank body 2 is continuously discharged through the reciprocating motion of the reaction tank sealing gasket 3 with the gas path. Thereby avoiding overpressure damage to the reactor vessel 2.
And a groove is formed in the position, which is vertical and coaxial with the exhaust hole, of the upper part of the reaction tank sealing interlayer 4 to form a fixed bolt slide way 9, and the length of the groove of the fixed bolt slide way 9 is limited by the telescopic distance of the pressure spring in the working process.
The upper part of the sealing gasket 3 of the reaction tank with the gas circuit is transversely provided with a hole, and the fixing bolt 8 passes through the sealing gasket 3 of the reaction tank with the gas circuit. The length of the fixing bolt 8 exceeds the diameter of the reaction tank sealing interlayer 4, so that the reaction tank sealing gasket 3 with the gas circuit cannot pop up the reaction tank sealing interlayer 4 downwards in the reciprocating motion process, and the end point of the upward motion ensures that the exhaust hole passages after being communicated are communicated all the time. In the vertical axis direction, the exhaust hole passage can not be dislocated due to the rotation of the reaction tank sealing interlayer 4, and the communication of the exhaust hole passage can also be ensured.
When the sealing assembly of the pressure reaction tank with the structure is used for acid removing operation, only the elastic force of the internal pressure spring needs to be changed into a small elastic force spring, and the reaction tank sealing gasket 3 with the gas circuit is ensured not to be compressed under the pressure of external atmospheric pressure under the vacuum condition. In the use process, due to the external atmospheric pressure, the reaction tank body 2 is not placed at the lower part of the sealing component of the pressure reaction tank with the structure, and the sealing of the whole set of vacuum device cannot be influenced. After the reaction tank body 2 is placed at the lower part of the sealing assembly of the pressure reaction tank with the structure, the sealing gasket 3 of the reaction tank with the gas path moves upwards to the exhaust port for communication due to external pressure, so that a vacuum passage is formed, and gas in the reaction tank body 2 is pumped out.
The cavity where the pressure spring 6 is located is relatively sealed, and in the reciprocating motion process of the reaction tank sealing gasket 3 with the gas circuit, after the top of the reaction tank sealing interlayer 3 is provided with a hole, pressure change cannot be generated in the cavity, and the normal work of the pressure spring 6 cannot be influenced.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
