Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a medical waste pressure position measurement system. Background Art

[0002] Medical waste treatment equipment uses high-temperature and high-pressure steam to treat medical waste. The sealing of the medical waste treatment chamber is a key technology. In order to improve the sealing state of the medical waste entrance and exit, a sealing ring is set at the feed inlet to strengthen the sealing after the feed door is closed. However, in actual use, due to the relative movement between the feed door sealing plate and the sealing ring, a large friction force is generated, causing wear on the sealing ring and reducing the reliability of the seal. At the same time, the medical waste treatment equipment is sterilized in a high-temperature and high-pressure environment, so the sealing door of the equipment has a strong resistance to pressure shock.

[0003] In actual applications, after medical waste enters from the entrance, it must be pressed down to enter the next step. The current structure does not measure the downward pressing position. The actual compression force is used as a reference. When it cannot be pressed down, the pressure is stopped or the compression position is set. When the compression position is reached, the compression is stopped. It cannot be adjusted according to the actual compression situation, which affects the implementation of the subsequent vacuum process.

[0004] Therefore, there is an urgent need for a system that can measure the downward pressure position at the inlet to ensure the sealing effect of the subsequent vacuum pumping of the feed inlet. Utility Model Content
