DETAILED DESCRIPTION

[0023] The specific implementation of the utility model will be further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot be used to limit the protection scope of the utility model.

[0024] A sealing door structure for a rice sterilization chamber, such as Figures 1-5 As shown, the device includes a sterilization chamber 1, which is a cylindrical cavity with an open end. A sealing door structure is provided on the open end for material to enter and exit. When the material to be sterilized enters the sterilization chamber 1 through the open end, the sealing door structure seals the sterilization chamber 1. The sealing door structure includes a flange cavity 2, a rotating sealing door 3, and a drive mechanism 4. The flange cavity 2 has a sealing door opening corresponding to the position of the open end. The flange cavity 2 is connected to the open end. In this device, the rotating sealing door 3 is placed inside the flange cavity 2. When the sterilization chamber 1 is pressurized, the rotating sealing door 3 can be pressed tightly against the outer opening 12, creating a tightening effect that prevents it from detaching, thus ensuring high safety.

[0025] Specifically, the rotating sealing door 3 includes a rotating shaft 5, a sealing door plate 6, and a door plate pusher 7. The rotating shaft 5 extends from the inside of the flange cavity 2 to the outside and is rotatably connected to the flange cavity 2. Its exterior is connected to the drive mechanism 4. One end of the rotating shaft 5 inside the flange cavity 2 is connected to the sealing door plate 6 and the door plate pusher 7. The door plate pusher 7 presses the sealing door plate 6 to seal the opening of the sealing door. In actual use, when it is necessary to open the sealing door, the drive mechanism 4 first pushes the sealing door structure inward to translate, and then controls its rotation, thereby opening the sealing door. In use, the door plate pusher 7 forms a rigid frame, which pushes the sealing door plate 6 to press against the outer opening 12, which can achieve a more flat press and avoid gaps, warping, etc.

[0026] Specifically, the flange cavity 2 includes a circular cylindrical flange 8 and a door flange 9. A sealing chamber 10 is formed inside the cylindrical flange 8 and the door flange 9, allowing the rotary sealing door 3 to move axially and rotate around the rotation axis 5. The sealing door opening includes an inner opening 11 and an outer opening 12. The inner opening 11 is sealed to an open valve, and the outer opening 12 mates with the rotary sealing door 3. The distance between the cylindrical flange 8 and the door flange 9 provides space for the rotary sealing door 3 to move between the inner opening 11 and the outer opening 12.

[0027] Furthermore, the center of the door flange 9 is provided with a through hole 13 for the rotating shaft 5 to pass through. The rotating shaft 5 is controlled by the drive mechanism 4 to have two control actions relative to the through hole 13. The first action is extension control, and the second action is rotation control. During extension control, the rotating shaft 5 is controlled to slide and extend relative to the through hole 13. During rotation control, the rotating shaft 5 is controlled to rotate relative to the through hole 13. In this way, the opening or closing of the sterilization chamber 1 is achieved through the two control actions.

[0028] Further, the outer opening 12 is located at the same position as the inner opening 11, and a sealing gasket 14 is arranged on the inner wall of the outer opening 12. The outer opening 12 is sequentially provided with a sealing door plate 6 and a door plate push frame 7 from the inner opening 11. The outer shape of the sealing door plate 6 is the same as that of the door plate push frame 7. The sealing door plate 6 is larger than the outer opening 12, and the door plate push frame 7 uniformly presses the sealing door plate 6 in the circumferential direction and presses the sealing gasket 14. When the sealing door plate 6 is pressed on the sealing gasket 14, the outer opening 12 can be effectively sealed, and the door plate is further pressed under the action of the internal steam pressure to improve the sealing effect.

[0029] Further, the sealing door plate 6 and the door plate push frame 7 are provided with elastic members 15 arranged at the four corners. The elastic members 15 can provide better pressing and sealing effect on the four corners of the sealing door plate 6.

[0030] Further, the driving mechanism 4 includes a frame body 16 and a translation frame 17. The frame body 16 is fixed to the outer side of the door flange 9, and a guide rod 18 is arranged in parallel in the frame body 16. The translation frame 17 is slidingly arranged on the guide rod 18, so that the translation frame 17 moves in the axial direction. The driving mechanism 4 further includes a translation driving part, which includes a translation push cylinder 19 fixedly arranged at the outer end of the frame body 16. The free end of the push cylinder penetrates through the frame body 16 and is connected to the translation frame 17 to drive the translation frame 17 to slide along the guide rod 18. The other side of the translation frame 17 is connected to the rotating shaft 5, so that the rotating shaft 5 moves in the axial direction with the translation frame 17. The driving mechanism 4 further includes a rotation driving part. The translation frame 17 is rotatably provided with a driving gear 20 and a driven gear 21 which are engaged with each other. The translation frame 17 is provided with a rotation driving cylinder 22, and the free end of the rotation driving cylinder 22 is connected to and controls the rotation of the driving gear 20 through a swing arm 23.

[0031] In actual control, the translation push cylinder 19 first pushes the translation frame 17 to move towards the inner opening 11, so that the sealing door plate 6 is separated from the sealing gasket 14. Then the rotation driving cylinder 22 pushes the swing arm to drive the driving gear 20 to rotate. The diameter of the driving gear 20 is larger than that of the driven gear 21, so that the swing arm 23 can drive the driven gear 21 to rotate by a larger angle at a smaller swing angle, and then the rotating sealing door 3 rotates by a larger angle, so that the sterilization cavity 1 is completely opened. Conversely, when it is necessary to close, the rotating sealing door 3 is first aligned with the outer opening 12 by the swing arm 23 controlled by the rotation driving cylinder 22, and then the rotating sealing door 3 is pulled outward by the translation push cylinder 19 to press the sealing door plate 6 on the sealing gasket 14 to achieve sealing.

[0032] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
