[0033] See also Figures 1 to 4 The medical waste treatment equipment of the embodiment of the utility model includes a crushing device 10 and a disinfection device 20.

[0034] The crushing device 10 is used to crush the medical waste. Thus, through the crushing process of the medical waste by the crushing device 10, the medical waste is dispersed, the volume becomes smaller, the quantity becomes larger, and the crushed waste is formed.

[0035] The disinfection device 20 includes a disinfection box 21 and a plurality of disinfection nozzles 221. The disinfection box 21 is located downstream of the crushing device 10, and a disinfection chamber 2101 connected to the crushing device 10 is formed in the disinfection box 21. In this way, the crushed waste formed by crushing can enter the disinfection chamber 2101.

[0036] A plurality of the disinfection nozzles 221 are arranged on the inner wall of the disinfection box 21 and are spaced apart along the circumference of the disinfection box 21 to form at least one annular spray body 22 , and each of the disinfection nozzles 221 has a nozzle 22101 opening toward the center of the annular spray body 22 .

[0037] In this way, compared with spraying disinfectant downward from the nozzle, the medical waste only receives disinfectant from above. The utility model first breaks the medical waste, and when disinfecting the broken waste, the disinfectant can spray hypochlorous acid disinfectant from the circumferential edge of the disinfection chamber 2101 to the center of the disinfection chamber 2101, so that the broken waste located in the disinfection chamber 2101 can receive the disinfectant sprayed from multiple directions on its outer peripheral side, and the disinfectant can fully contact the outer surface of the broken waste, so that the medical waste treatment equipment of the utility model has a good disinfection treatment effect on the medical waste.

[0038] According to some preferred embodiments of the present invention, refer to Figure 3 There are multiple annular spray bodies 22, and the multiple annular spray bodies 22 are arranged at intervals along the vertical direction. Such an arrangement can further improve the disinfection treatment effect of the disinfection device 20 on the crushed waste.

[0039] According to some preferred embodiments of the present invention, refer to Figure 5 and Figure 6 The crushing device 10 includes a crushing box 11, a crushing shaft 12 and a plurality of crushing bodies 13. A crushing chamber 1101 is formed in the crushing box 11. The crushing shaft 12 is rotatably disposed in the crushing chamber 1101. The plurality of crushing bodies 13 are arranged at intervals in the vertical direction. Each layer of the crushing body 13 includes a plurality of crushing knives 131. One end of the plurality of crushing knives 131 is close to each other and connected to the crushing shaft 12, and the other end is far away from each other.

[0040] In this way, when the medical waste enters the crushing chamber 1101, the crushing shaft 12 rotates and drives the multiple crushing knives 131 on each layer to rotate, so that the crushing knives 131 can crush the large volume of medical waste into small particles, which has a good crushing effect and is also conducive to the subsequent disinfectant to fully contact with the medical waste and fully disinfect the medical waste.

[0041] According to some preferred examples of the present invention, see Figure 5 and Figure 6 The crushing device 10 further includes a first filter plate 14. The first filter plate 14 is disposed in the crushing chamber 1101 and below the crushing body 13, and is used to filter the crushed waste.

[0042] In this way, after the crushing element 12 crushes the medical waste, the crushed waste with a particle size small enough after crushing can pass through the filter holes of the first filter plate 14 and then enter the subsequent disinfection device 20. The crushed waste with a larger particle size after crushing is trapped above the first filter plate 14 and then crushed again by the crushing element 12 until the particle size is small enough to pass through the filter holes of the first filter plate 14.

[0043] Thus, the first filter plate 14 can screen the crushed waste, facilitating the subsequent recycling of the crushed waste, such as heating and melting the crushed waste with a small particle size and made of plastic to synthesize new plastic products. At the same time, the first filter plate 14 can also assist the crushing element 12 in crushing, so that the crushing element 12 can crush the volume of the medical waste into a small enough size.

[0044] According to some preferred examples of the present invention, see Figure 5 The crushing device 10 further includes a microwave generator 15. The microwave generator 15 is disposed in the crushing chamber 1101 and below the first filter plate 14.

[0047] In this way, the second filter plate 23 can filter the sterilized crushed waste again, and the sterilized crushed waste with a smaller particle size can pass through the filter holes of the second filter plate 23 and then enter the subsequent processing device. The crushed waste with a larger particle size is retained above the second filter plate 23. Therefore, the second filter plate 23 can screen the crushed waste, facilitating the subsequent recycling of the crushed waste, such as heating and melting the crushed waste with a smaller particle size and made of plastic to synthesize new plastic products.

[0048] According to some preferred embodiments of the present invention, refer to Figure 2 and Figure 7 The medical waste treatment equipment further comprises a drying device 30. The drying device 30 is arranged downstream of the disinfection device 20 and is used to dry the broken waste after disinfection.

[0049] In this way, the drying device 30 can heat and evaporate the disinfectant sprayed on the crushed waste at high temperature, thereby facilitating the collection and treatment of the crushed waste. In addition, the drying method can also use high temperature to further kill bacteria remaining on the crushed waste, thereby further sterilizing the crushed waste.

[0050] According to some preferred embodiments of the present invention, refer to Figure 2 The drying device 30 includes a drying box 31 and a heating element 32. The drying box 31 is provided with a heating chamber 3101 connected to the disinfection chamber 2101, for receiving the sterilized crushed waste. The heating element 32 is provided in the drying box 31, for heating the crushed waste to dry it.

[0051] In this way, when the heating element 32 is working, the heating element 32 heats the heating chamber 3101, thereby drying the crushed waste in the heating chamber 3101.

[0052] According to some preferred examples of the present invention, the heating element 32 is configured as a heating resistance wire. The heating resistance wire is spirally wound around the outer circumference of the drying box body 31 .

[0053] In this way, the heating element 32 has a good heating effect on the crushed waste, and can dry the crushed waste in the heating chamber 3101 quickly and evenly.

[0054] According to some preferred embodiments of the present invention, refer to Figure 7 The medical waste treatment equipment further comprises a first delivery pump 40. The suction port of the first delivery pump 40 is connected to the crushing device 10, and the discharge port is connected to the disinfection device 20.

[0055] In this way, the first delivery pump 40 can pump the crushed waste material crushed in the crushing device 10 to the disinfection device 20 , so that the crushed waste material can be disinfected by the disinfection device 20 in time.

[0056] According to some preferred embodiments of the present invention, refer to Figure 7 The medical waste treatment equipment further comprises a second delivery pump 50. The suction port of the second delivery pump 50 is connected to the disinfection device 20, and the discharge port is connected to the drying device 30.

[0057] In this way, the second delivery pump 50 can pump the sterilized crushed waste in the sterilizing device 20 to the drying device 30 , so that the sterilized crushed waste can be dried by the drying device 30 in time.
