Description

Technical Field

[0001] The utility model relates to the technical field of sterilization chambers, and more specifically, it relates to a sterilization chamber structure of a high-temperature sterilization furnace. Background Art

[0002] A high-temperature sterilization furnace heats water through the furnace and transports the water vapor to the sterilization chamber through a pipeline to perform high-temperature sterilization treatment on the materials in the sterilization chamber. The water vapor moves upward in the sterilization chamber. When it contacts the top cover plate, since the cover plate is in contact with the outside air, the temperature of the cover plate is relatively low, and the water vapor is likely to condense into water droplets at the cover plate. When the water droplets drip down, they are likely to drip onto the surface of the materials, resulting in excessive humidity on the surface of the materials and affecting the quality of the materials. In addition, after the sterilization chamber is used, the internal temperature is relatively high. If the worker directly opens the sterilization chamber, the water vapor in the sterilization chamber will be discharged from the opening, which is likely to scald the worker. Therefore, generally, it is necessary to wait for a period of time until the temperature in the sterilization chamber drops to a certain level. At this time, the sterilization chamber is manually opened to take out the materials. This method has a long waiting time and affects the sterilization efficiency. Content of the Utility Model

The opening and closing mechanism includes a fixed seat 8, a mounting seat 9, an opening and closing cylinder 10, and a first connecting seat 11. A box door 12 is hinged on one side of the box body 1. The fixed seat 8 is fixedly arranged on one side of the box body 1. The mounting seat 9 is fixedly sleeved outside the opening and closing cylinder 10, and a rotating rod 13 is provided on the mounting seat 9. The rotating rod 13 is rotatably connected with the fixed seat 8. The drainage mechanism includes a first sealing seat 16, a second sealing seat 17, a fixed rod 18, and a compression spring 19.

The top of the second sealing seat 17 fits with the bottom of the first sealing seat 16. The two ends of the compression spring 19 are respectively fixedly connected with the second sealing seat 17 and the fixed rod 18. A guide rod 20 is provided on the lower surface of the second sealing seat 17. The bottom end of the guide rod 20 penetrates through the fixed rod 18 and is slidably connected with the fixed rod 18.

[0029] In this embodiment, the material to be sterilized is placed on the support plate 22, and the support plate 22 is placed on the receiving plate 21. Both the air inlet pipe 24 and the air outlet pipe 25 are connected to the steam generating end of the external sterilization furnace. Steam is introduced into the box body 1 through the air inlet pipe 24 to sterilize the material inside the box body 1. The steam moves upward and is discharged from the air outlet pipe 25. During this process, some water droplets condense on the lower surface of the cover plate 2 and slide along the arc surface 26 to the upper side of the annular frame 3. When the condensed water droplets are relatively large, they drip into the lower water receiving groove 6 and are discharged into the external water storage box 5 along the connecting pipe 4.

During this process, some water droplets condense on the lower surface of the cover plate 2 and slide along the arc surface 26 to the upper part of the annular frame 3. When the condensed water droplets are relatively large, they drip into the water receiving tank 6 below and are discharged to the external water storage box 5 along the connecting pipe 4. When the pressure of the water volume in the water storage box 5 on the second sealing seat 17 is greater than the pressure of the compression spring 19, at this time, the compression spring 19 continues to be compressed, the second sealing seat 17 leaves the first sealing seat 16, and the water in the water storage box 5 is discharged.

[0033] After the sterilization is completed, first stop the entry of water vapor, start the opening and closing cylinder 10 to make it extend, drive the box door 12 to rotate and open, which is convenient for the water vapor in the box body 1 to be discharged. After the water vapor is discharged, at this time, the worker can wear heat-insulating gloves and take out the support plate 22 from the box body 1. During the rotation of the box door 12, the mounting seat 9 and the rotating rod 13 rotate around the axis of the rotating rod 13 to realize the process of the opening and closing cylinder 10 extending to drive the box door 12 to open.
