By disposing the crushing knife set 3 and the sterilization assembly 4 in the bottom bucket 1, and when the crushing knife set 3 is rotating, the medical waste can be broken, and the crushing knife set 3 and the inner wall of the bottom bucket 1 can crush the medical waste. The materials are rubbed, so that the temperature in the sterilization barrel continues to rise, thereby achieving friction heat sterilization of medical waste. At the same time, in the process of rubbing medical waste materials, larger materials can also be removed through friction. Granulation to facilitate subsequent discharge of medical waste.

The connecting barrel 2 and the bottom barrel 1 are connected through a flange 6 .

The barrel body is arranged in a segmented manner with bottom barrel 1 and connecting barrel 2, which facilitates subsequent cleaning-level maintenance of the crushing knife unit 3. At the same time, the flange connection method is used to improve the stability and sealing of the connection. This further improves the safety performance of medical waste treatment and prevents waste gas leakage.

An end surface of the connecting barrel 2 away from the bottom barrel 1 is provided with a flange 21 extending in the horizontal direction, and a sealing cover 7 is provided on the flange 21, and the sealing cover 7 is snap-fitted to the connecting barrel 2 .

By providing the flange 21 on the connecting barrel 2 and the sealing cover 7 fitting the flange 21, the barrel can be better sealed. At the same time, the sealing cover 7 faces the connecting barrel 2 and is opposite to the flange 21. A snap-fit portion 71 is provided at one end of the flange 21 , a locking hole 211 is provided on the flange 21 , and a locking piece for locking the snap-fit portion 71 is provided at a position where the connecting barrel 2 is located below the flange 21 .
