[0002] A large number of surgeries are performed in hospitals every day, and a large amount of medical waste is generated during each surgery. Medical waste refers to the contaminated garbage produced by hospitals that has come into contact with patients' blood, flesh, etc., including used cotton balls, gauze, adhesive tapes, waste water, disposable medical devices, postoperative waste products, and so on.

[0003] Medical waste may contain a large number of pathogenic microorganisms and harmful chemical substances. If not properly disposed of and randomly stacked in the open air, it will not only occupy a large amount of land, resulting in a reduction of available land resources, but also a large amount of toxic waste residues or waste liquids will flow everywhere in nature and easily come into contact with the soil. Some medical and health institutions even simply bury medical waste, which causes great pollution to the soil. In addition, medical waste can pollute water bodies through various channels. For example, it can enter rivers and lakes along with surface runoff, or fall into water bodies by migrating with the wind.

[0029] During specific use, the garbage bag 10 is fixed at the discharge port 8, and the medical waste is fed into the device from the feed hopper 5, and enters the crushing box 2 through the receiving hopper 3. The crushing device inside the crushing box 2 crushes and destroys the medical waste. At the same time, the disinfection pump conveys the disinfectant in the disinfection box 11 to the nozzle 13 and sprays it on the crushed medical waste to disinfect the medical waste. The medical waste after destruction and disinfection enters the compression box 6 through the discharge port 4 and the crushed material inlet 7 in turn, and is compressed by the compression and conveying device in the compression box 6 and conveyed to the garbage bag 10. After the garbage bag 10 is filled with garbage, it is replaced in time.

[0030] In order to achieve the purpose of thorough disinfection of medical waste, preferably, the pulverizing device includes two pulverizing rollers 14 rotatably connected to the inside of the pulverizing box 2, a motor 15 is provided on the outer wall of the box body 1, and the output end is fixedly connected to one of the pulverizing rollers 14, a driving gear 16 is coaxially provided on the pulverizing roller 14 fixedly connected to the output end of the motor 15, and the other pulverizing roller 14 is coaxially provided with a driven gear 17 meshing with the driving gear 16.

[0032] In order to achieve the purpose of compressing and conveying shredded medical waste, preferably, the compression and conveying device includes a screw conveyor 18 rotatably connected to the inside of the compression box 6, the spiral turns on the screw conveyor 18 gradually change from sparse to dense from right to left, the driving gear 16 is coaxially provided with a first driving pulley 19, the screw conveyor 18 is coaxially provided with a first driven pulley 20, and the first driving pulley 19 and the first driven pulley 20 are transmission-connected by a first belt 21.

[0033] When the motor 15 is working, it drives the first active pulley 19 to rotate synchronously. The first active pulley 19 drives the screw conveyor 18 to rotate through the first belt 21 and the first driven pulley 20. The screw conveyor 18 conveys the shredded medical waste to the discharge port 8. Since the spiral turns on the screw conveyor 18 change from sparse to dense in the conveying direction, the shredded medical waste is gradually compressed during the conveying process and finally enters the garbage bag 10 from the discharge port 8, thereby reducing the space occupied by medical waste and reducing the cost of storing and transporting medical waste.
