Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment equipment technology, and in particular to an opening and closing mechanism for the feed inlet of a high-pressure sterilization tank. Background Technology

[0002] Traditional autoclaves are commonly used in various industries such as biology, medicine, and food. Their core function is to kill or remove microorganisms from materials through a high-temperature, high-pressure environment, ensuring the sterility of the products. However, traditional door mechanisms often employ relatively simple sealing structures, such as flat seals or simple rubber ring seals. These designs are prone to leaks when exposed to high-pressure steam due to material aging, wear, or improper installation. Poor sealing performance not only leads to steam leakage, affecting sterilization effectiveness, but also poses a risk of burns to operators due to steam leakage, while increasing energy consumption. Furthermore, some traditional autoclave door mechanisms are complex in design, requiring considerable force or specific tools to open and close, which not only increases the difficulty of operation but may also cause safety issues due to improper operation.

The plurality of second wedge teeth have a front end and a gradually expanding rear end, and the rear end is fixedly connected to the door body 1. Preferably, the plurality of second wedge teeth and the door body 1 are integrally formed. This integral forming design helps to ensure a firm connection and tight fit between the wedge teeth and the door body 1, thereby improving the strength and stability of the entire structure. The size of the second preset interval of the plurality of second wedge teeth can be determined according to actual needs and design requirements to ensure that the wedge teeth can be evenly distributed on the edge without interfering with each other or affecting their function. Preferably, the number of the plurality of second wedge teeth can be equal to the number of the plurality of first wedge teeth. The size of the second wedge teeth 3 is slightly smaller than the first preset interval, and the size of the first wedge teeth 2 is slightly smaller than the second preset interval to ensure that the second wedge teeth 3 pass through the first preset interval and the first wedge teeth 2 pass through the second preset interval, thereby realizing the unlocking and locking of the door body 1 and the feed inlet.

The second wedge 3 of the door body 1 passes through the first preset interval, and the first wedge 2 of the feed inlet passes through the second preset interval. Then, the second push rod 52 extends and drives the door body 1 to rotate around the rotation axis. The door body 1 and the feed inlet are nested together to achieve locking. When the feed inlet is opened, the second push rod 52 shortens and drives the door body 1 to rotate around the rotation axis, so that the first wedge 2 is aligned with the second preset interval and the second wedge 3 is aligned with the first preset interval. Then, the first push rod 62 shortens and pulls the top plate 12 to rise. The second wedge 3 of the door body 1 passes through the first preset interval, and the first wedge 2 of the feed inlet passes through the second preset interval. The door body 1 and the feed inlet are separated, and the feed inlet is opened.
