Secondly, the second sealing ring 206 is squeezed and squeezed with the movable ring 205 at the same time. The movable ring 205 moves downward under the action of the squeezing force. One end surface of the movable ring 205 is fixedly connected to one end surface of the spring 204. The spring 204 is deformed under the squeezing of the movable ring 205 and recovers the deformation in a vertical downward direction. The connecting ring 203 fixedly connected to the lower end surface of the spring 204 is squeezed by the spring 204 and begins to move.

The fixed table 201 is subjected to the force provided by the degassing equipment 1, and the force is applied to the first sealing ring 202. The first sealing ring 202 is subjected to forces in two completely opposite directions until the two forces are equal in size. At this time, the sealing mechanism 2 reaches a completely sealed state.

[0033] Furthermore, the heat dissipation mechanism 3 includes a protective sleeve 301, a fan 302, a bolt 303, a protective plate 304 and a screw hole 305.

[0037] Furthermore, a first chamfered surface 2021 is provided on the outer ring surface of the first sealing ring 202. The first chamfered surface 2021 cooperates with the second chamfered surface 181 so that when the second chamfered surface 181 is pressed down with the rubber ring 18, the first sealing ring 202 is squeezed through the rubber ring 18, thereby further enhancing the sealing performance of the first sealing ring 202.

[0038] Furthermore, a cylinder 11 is connected to the upper surface of the degassing device 1 , and a lifting ring 12 is connected to one end of the telescopic end of the cylinder 11 extending into the interior of the degassing device 1 , and the lifting ring 12 is lifted and lowered by the cylinder 11 .

[0040] Furthermore, a motor 14 is connected to the upper surface of the lifting ring 12, and a stirring shaft 15 is connected to the output shaft of the motor 14. A stirring blade 16 is connected to the outer surface of the stirring shaft 15. The motor 14 is driven to rise and fall by the lifting ring 12, and the stirring shaft 15 is driven by the motor 14, so that the stirring shaft 15 drives the stirring blade 16 to stir, thereby turning over the raw materials in the degassing machine.

[0041] Furthermore, a spring 111 is sleeved on the outer side of the output end of the cylinder 11, and an extrusion ring 17 is abutted at the bottom end of the spring 111. A rubber ring 18 is provided at the bottom end of the extrusion ring 17. A second chamfered surface 181 is provided on the inner ring surface of the rubber ring 18. The second chamfered surface 181 abuts against the first chamfered surface 2021. A push ring 19 is abutted on the top end of the spring 111. The push ring 19 is connected to the outer surface of the output end of the cylinder 11. The push ring 19 is driven by the cylinder 11, and the spring 111 is driven by the push ring 19. The extrusion ring 17 is pressed down by the spring 111, and the rubber ring 18 is pressed down by the extrusion ring 17.

[0042] Working principle: First, put the product to be degassed into the cavity, apply pressure to the cover of the degassing equipment 1 so that one end surface of the cover fits tightly with the upper end surface of the sealing seat 207, and the sealing seat 207 squeezes the second sealing ring 206 under the action of the pressure. Secondly, the second sealing ring 206 is squeezed and squeezed with the movable ring 205 at the same time. The movable ring 205 moves downward under the action of the squeezing force. One end surface of the movable ring 205 is fixedly connected to one end surface of the spring 204. The spring 204 is deformed under the squeezing of the movable ring 205 and recovers the deformation in a vertical downward direction. The connecting ring 203 fixedly connected to the lower end surface of the spring 204 is squeezed by the spring 204 and begins to move. Finally, the first sealing ring 202 is deformed under the squeezing of the connecting ring 203 and squeezes the fixed table 201. The lower surface of the fixed table 201 is fixedly connected to the degassing equipment 1. The fixed table 201 is squeezed by the degassing equipment 1 The force provided is applied to the first sealing ring 202, and the first sealing ring 202 is subjected to two forces in completely opposite directions until the two forces are equal in magnitude. At this time, the sealing mechanism 2 reaches a completely sealed state. When the degassing device 1 needs to be used, first, a bolt 303 is used to penetrate the screw hole 305 opened on the surface of one side of the protective plate 304, so that the protective plate 304 and the outer surface of the degassing device 1 form a stable fixed connection, thereby preventing accidental touching of the rotating fan 302. Finally, the bolt 303 is used to penetrate the protective cover 301, so that the protective cover 301 and the inner surface of the degassing device 1 form a stable fixed connection and limit the fan 302 at the same time. Secondly, the power of the fan 302 is turned on to put it in a working state. The rotation of the fan 302 can speed up the reduction of air circulation in the degassing device 1 and reduce the working temperature of the equipment in the degassing device 1, thereby achieving a heat dissipation effect on the degassing device 1.
