The working principle of the invention is as follows:

firstly, filling disinfectant into a disinfection tank 1, and filling the disinfectant into a position where the liquid level of the disinfectant is flush with the lower opening edge of a floating garbage discharge port 2; then the sealing cover plate 14 is buckled, and the medical waste to be treated is directly thrown into the disinfection tank 1 through the feeding port 15 on the sealing cover plate 14. At the moment, the heavier medical waste (namely sinking medical waste) can sink to the crushing roller 4 in the disinfection tank 1, and fall to the conical tank bottom at the bottom of the disinfection tank 1 after being crushed by the rotating crushing roller 4, and wait for the opening of the material discharge port 6 to be discharged together; the light medical waste (namely floating medical waste) floats on the liquid level of the disinfectant under the action of buoyancy, the air blowing nozzle 3 is opened to blow air to the floating waste discharge port 2, and the air blowing nozzle 3 is tightly attached to the upper part of the liquid level of the disinfectant, so that the liquid level of the disinfectant is blown, the liquid level flows towards the floating waste discharge port 2, the floating medical waste is pushed to flow to the floating waste discharge port 2, and the floating medical waste is discharged out of the disinfection tank 1 through the floating waste discharge port 2.

The floating medical garbage pushed out of the disinfection tank 1 falls onto the inclined conveyer belt 20.1, is driven by the inclined conveyer belt 20.1, and enters the incinerator 17 through the horizontal conveyer belt 20.2, the lifting auger 21.1 and the translation auger 21.2 to be incinerated; the bottom ash after incineration can be cleaned out of the incinerator 17 and can be buried after harmless treatment, the fly ash generated in the incineration process can enter the fly ash solidification treatment equipment 28 through the smoke exhaust pipeline 19, after the fly ash is solidified in the fly ash solidification treatment equipment 28, harmless and pollution-free gas is directly discharged into the air, and solid ash can be buried directly.

When a certain amount of sinking medical garbage debris is accumulated in the disinfection tank 1, discharging operation can be carried out, at the moment, the opening and closing valve 9 on the liquid discharge pipe 10 is firstly opened to discharge disinfection liquid in the disinfection tank 1, so that only a small part of the disinfection liquid at the bottom of the conical tank and the sinking medical garbage debris are mixed together in the disinfection tank 1, then the sealing plate 7 on the material discharge port 6 is opened, so that the residual small part of the disinfection liquid and the sinking medical garbage debris are discharged out of the disinfection tank 1 together and fall into the material receiving trolley 13 below to be cleaned away; in addition, a small part of residual disinfectant can also soak the sunk medical waste residues, so that the sunk medical waste residues can be smoothly discharged out of the disinfection tank 1.
