[0032] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0033] As Figures 1-9 shown, a medical waste sterilization device includes a microwave sterilizer 4, a steam sterilizer 5, a housing 1, a crushing component 2, and a sorting component 3. Among them, the microwave sterilizer 4 and the steam sterilizer 5 are prior arts. In this application, the microwave sterilizer 4 is mainly used for sterilizing non-metallic waste, and the steam sterilizer 5 is mainly used for sterilizing metal materials. The housing 1 mainly plays a role in installation and support, can provide an installation carrier for the corresponding parts, and can isolate the sterilization parts from the external environment to a certain extent, improving the safety of the device during use.

[0034] As Figure 1 shown, the housing 1 is provided with a feed inlet 11. The feed inlet 11 mainly plays a role in feeding. Medical waste can be put into the interior of the housing 1 through the feed inlet 11, thus facilitating further sterilization operations.

[0035] In addition, as Figure 1 and Figure 3As shown, the crushing assembly 2 is arranged at the feed port 11, and is used to crush medical waste. Specifically, the crushing assembly 2 includes: a first toothed roller 21 and a second toothed roller 22 with two axes parallel to each other, one end of the first toothed roller 21 passes through the housing 1 and is fixedly connected to a first gear 23, one end of the second toothed roller 22 passes through the housing 1 and is fixedly connected to a second gear 24 adapted to the first gear 23, and a first motor 25 is fixedly connected to the housing 1. The first motor 25 is fixedly connected to the outside of the housing 1, and a pulley assembly 26 is connected between the output end of the first motor 25 and the second toothed roller 22. Among them, the first toothed roller 21 and the second toothed roller 22 are mainly used to crush medical waste. When in use, the first motor 25 is started, and the first motor 25 drives the second toothed roller 22 to rotate through the pulley assembly 26. The rotation of the second toothed roller 22 can drive the first toothed roller 21 to rotate through the cooperation between the second gear 24 and the first gear 23, so that the first toothed roller 21 and the second toothed roller 22 can rotate at the same time and in opposite directions. At this time, the medical waste is put between the first gear roller 21 and the second gear roller 22 , so that the medical waste can be flattened or crushed by the first gear roller 21 and the second gear roller 22 .

[0036] In addition, if Figures 3-9 As shown, the sorting component 3 is arranged inside the shell 1, and is mainly used to separate the crushed metal waste and non-metal waste. The sorting component 3 includes a first conveyor belt 31, a second conveyor belt 32, a buoyancy screening component 33, a power component 34 and a first conveying channel 35. Among them, the first conveyor belt 31 is used to transport the waste crushed by the crushing component 2 to the buoyancy screening component 33. A plurality of magnets 324 are fixedly connected to the second conveyor belt 32, and the magnets 324 are used to attract the magnetic metal waste on the first conveyor belt 31, and follow the movement of the second conveyor belt 32, and then transport it toward the steam sterilizer 5 through the first conveying channel 35. Among them, the first channel is a trumpet-shaped structure, and its end with a small diameter is connected to the inside of the steam sterilizer 5. The first conveying channel 35 includes a bottom plate 351 and a limit plate 352 fixedly connected to the inner wall of the shell 1, and the bottom plate 351 is arranged below the second conveyor belt 32 and is an inclined structure. Specifically, the height of the end of the bottom plate 351 close to the crushing assembly 2 from the ground is higher than the height of the end of the bottom plate 351 away from the crushing assembly 2. In this way, if the metal waste attracted by the magnet 324 falls during transportation, it will fall on the bottom plate 351 and slide along the bottom plate 351 into the steam sterilizer 5 under the action of gravity.

[0037] The limiting plate 352 is vertically arranged, and the top of the limiting plate 352 is flush with the bottom of the end of the second conveyor belt 32 away from the crushing assembly 2, so that the limiting plate 352 can be used to block and guide the metal waste attracted by the magnet 324 on the outer wall of the second belt body 323, so that it falls into the steam sterilizer 5.

[0038] The buoyancy screening assembly 33 is mainly used to screen the remaining non-metal waste with a density less than that of water and metal waste with a density greater than that of water on the first conveyor belt 31. Then, the waste with a density less than that of water is transported towards the microwave sterilizer 4, and the waste with a density greater than that of water is transported towards the steam sterilizer 5. The power assembly 34 is used to provide power for the first conveyor belt 31 and the second conveyor belt 32. It should be noted that since metal will affect the sterilization effect of microwaves, through the above screening, most of the metal waste can be separated from the non-metal waste, and the metal waste can be sterilized separately by the steam sterilizer 5, so that the sterilization effect of the microwave sterilizer 4 can be better exerted.

[0039] It should be noted that some metal box-shaped medical wastes with good ductility may not be completely crushed after being crushed by the crushing assembly 2. Such box-shaped wastes may float in water, and it is not completely reliable to screen them directly by the buoyancy screening assembly 33. Therefore, it is necessary to first use the magnet 324 for attraction.

[0040] Further, as Figure 5 and Figure 6 shown, a conveying plate 12 with an inclined structure is fixedly connected inside the housing 1. The conveying plate 12 mainly serves to transport the waste crushed by the crushing assembly 2. One end of the conveying plate 12 is arranged below the first toothed roller 21 and the second toothed roller 22, and the other end of the conveying plate 12 is arranged above the first conveyor belt 31. Specifically, the height of one end of the conveying plate 12 from the ground is higher than the height of the other end of the conveying plate 12 from the ground. In this way, the waste crushed by the crushing assembly 2 will first fall into one end of the conveying plate 12 and then slide along the conveying plate 12 to the first conveyor belt 31 under the action of gravity, so as to better automatically transport the waste.

[0041] Further, as Figure 5 and Figure 6 shown, a vibrating plate 13 is arranged on the side of the conveying plate 12 facing the crushing assembly 2. One side of the vibrating plate 13 close to one end of the conveying plate 12 is fixedly connected to the conveying plate 12, and a vibrator 14 is arranged between the vibrating plate 13 and the conveying plate 12. The vibrator 14 is fixedly connected to the conveying plate 12 and contacts the vibrating plate 13. It should be noted that the other side of the vibrating plate 13 is in a free state, which is convenient for the vibrating plate 13 to vibrate and makes the vibrating plate 13 not easily damaged. During use, the waste crushed by the crushing assembly 2 will fall onto the vibrating plate 13. At this time, the vibrator 14 is turned on, and the vibrator 14 will drive the vibrating plate 13 to vibrate. In this way, the crushed metal waste and non-metal waste can be further separated, facilitating subsequent screening. Moreover, the vibration of the vibrating plate 13 can also reduce the adhesion and accumulation of waste on the vibrating plate 13 and the conveyor, which is beneficial to the transportation of waste.

[0042] In addition, as Figures 5-9 shown, the first conveyor belt 31 includes a first driving shaft 311 and a first driven shaft 312 whose axes are parallel to each other, and a first belt body 313 adapted to the first driving shaft 311 and the first driven shaft 312. The second conveyor belt 32 includes a second driving shaft 321 and a second driven shaft 322 whose axes are parallel to each other, and a second belt body 323 adapted to the second driving shaft 321 and the second driven shaft 322. The power assembly 34 cooperates with the first driving shaft 311 and the second driving shaft 321 at the same time to drive the first driving shaft 311 and the second driving shaft 321 to rotate in opposite directions. In this way, both the metal waste attracted by the magnet 324 and the remaining non-magnetic waste can be transported in the same direction, which is convenient for the subsequent transportation and treatment of the waste.

[0043] Among them, the power assembly 34 includes a third gear 341, a fourth gear 342, a fifth gear 343 and a second motor 344. One end of the first driving shaft 311 extends to the outside of the housing 1 and is fixedly connected to the third gear 341. One end of the second driving shaft 321 extends to the outside of the housing 1 and is fixedly connected to the fourth gear 342. The second motor 344 is fixedly connected to the housing 1, and the output end of the second motor 344 is fixedly connected to the fifth gear 343. The third gear 341 is adapted to the fourth gear 342 and the fifth gear 343 at the same time. When in use, the second motor 344 is started, and the second motor 344 will drive the fifth gear 343 to rotate. The rotation of the fifth gear 343 can drive the first driving shaft 311 to rotate through the cooperation with the third gear 341, so as to drive the first conveyor belt 31 to move. Through the cooperation between the third gear 341 and the fourth gear 342, the fourth gear 342 can be driven to rotate, so as to drive the second driving shaft 321 to rotate, and further drive the second conveyor belt 32 to move. In this way, the transportation of the waste can be realized.

[0044] Furthermore, as Figure 9 shown, annular grooves 27 are formed along the axial direction on both the second driving shaft 321 and the second driven shaft 322 to avoid the magnet 324. It should be noted that in order to facilitate the separation of the magnetic metal waste from the second conveyor belt 32, the magnet 324 can be arranged on the inner wall of the second belt body 323. The annular grooves 27 mainly play a role of avoidance. During the movement of the second belt body 323, the second belt body 323 will drive a plurality of magnets 324 to move together. During the movement of the magnet 324, the annular grooves 27 can avoid the magnet 324, so as to avoid interference between the magnet 324 and the second driving shaft 321 and the second driven shaft 322.

[0045] In addition, as Figures 5-8As shown in the figure, the buoyancy screening assembly 33 includes a processing box 331 fixedly connected inside the housing 1, a pushing assembly 332, a second conveying channel 333, and a third conveying channel 334. Inside the processing box 331, a horizontally placed partition plate 3311 is fixedly connected. The partition plate 3311 can divide the processing box 331 into a buoyancy chamber 3312 above and a water collection chamber 3313 below. A filter screen 33111 is provided on the partition plate 3311. The filter screen 33111 can communicate the buoyancy chamber 3312 with the water collection chamber 3313, and a one-way valve 33112 cooperating with the filter screen 33111 is provided on the partition plate 3311. Among them, the buoyancy chamber 3312 is mainly used to load water, and use the buoyancy of water to separate non-metals with a density less than that of water, mainly plastics, and metals with a density greater than that of water and without magnetism. Specifically, when the remaining waste after being attracted by the magnet 324 continues to be transported on the first conveyor belt 31, the waste on the first conveyor belt 31 will fall into the buoyancy chamber 3312. At this time, non-metallic materials with a density less than that of water will float on the water surface, and metallic materials with a density greater than that of water and without magnetism will fall onto the partition plate 3311.

[0046] The filter screen 33111 mainly plays a filtering role, and can reduce waste from falling into the water collection chamber 3313 during the process of introducing the water in the buoyancy chamber 3312 into the water collection chamber 3313. The one-way valve 33112 can be an electromagnetic one-way valve 33112, which mainly controls the communication between the buoyancy chamber 3312 and the water collection chamber 3313.

[0047] A partition assembly 336 is provided on one side of the buoyancy chamber 3312 close to the crushing assembly 2. The partition assembly 336 is used to selectively partition the internal space of the buoyancy chamber 3312 in the vertical direction. Specifically, the partition assembly 336 includes a partition board 3361 and a second cylinder 3362. The partition board 3361 is horizontally slidably connected to one side of the buoyancy chamber 3312 close to the crushing assembly 2. The second cylinder 3362 is fixedly connected to the housing 1, and its telescopic end is fixedly connected to the partition board 3361 to selectively push the partition board 3361 into the buoyancy chamber 3312. A plurality of filter holes are provided on the partition board 3361. It should be noted that the end of the partition board 3361 away from the crushing assembly 2 is flush with the inner wall of the processing box 331 in the initial state, so as to reduce the interference of the partition board 3361 on the waste screening process. During use, when all the remaining waste on the first conveyor belt 31 falls into the buoyancy chamber 3312 and stands for a period of time, the second cylinder 3362 is started at this time to push the partition board 3361 into the interior of the buoyancy chamber 3312. Then the one-way valve 33112 is opened, and the water inside the buoyancy chamber 3312 will flow into the water collection chamber 3313 through the filter screen 33111 and the one-way valve 33112 for collection, and the original waste with a density less than that of water will fall onto the partition board 3361, and the remaining waste with a density greater than that of water will fall onto the partition board 3361.

[0048] As an optional embodiment, a water inlet communicating with the buoyancy chamber 3312 and a water outlet communicating with the water collection chamber 3313 may be provided on the housing 1, which facilitates filling water into the buoyancy chamber 3312 and also facilitates treating the water in the water collection chamber 3313 for repeated use.

[0049] As Figure 5 shown, a sealing assembly 335 is provided on the side of the treatment tank 331 away from the crushing assembly 2 to selectively close and open the side of the buoyancy chamber 3312 away from the crushing assembly 2. That is to say, the sealing assembly 335 can seal the buoyancy chamber 3312 or release the seal of the buoyancy chamber 3312. Specifically, the sealing assembly 335 includes a sealing plate 3351 and a first cylinder 3352 fixedly connected to the bottom of the sealing plate 3351. The sealing plate 3351 is vertically slidably connected to the treatment tank 331, and the first cylinder 3352 drives the sealing plate 3351 to move up and down to selectively close and open the side of the buoyancy chamber 3312 away from the crushing assembly 2. During use, after the one-way valve 33112 is opened and before the water completely enters the water collection chamber 3313, the sealing plate 3351 is always in a state of sealing the buoyancy chamber 3312. When the water completely enters the water collection chamber 3313, the first cylinder 3352 is started at this time. The first cylinder 3352 contracts to drive the sealing plate 3351 to descend, so that the side of the buoyancy chamber 3312 away from the crushing assembly 2 is in an open state. At this time, the pushing assembly 332 is used to push the waste material with a density greater than that of water on the partition plate 3311 to one end of the second conveying channel 333, and then it is conveyed to the steam sterilizer 5 from the other end of the second conveying channel 333. And the waste material with a density less than that of water on the isolation plate 3361 is pushed to one end of the third conveying channel 334, and then it is conveyed to the microwave sterilizer 4 from the other end of the third conveying channel 334.

[0050] It should be noted that the bottom of one end of the second conveying channel 333 is flush with the partition plate 3311, and the bottom of one end of the third conveying channel 334 is flush with the isolation plate 3361, which can reduce the leakage of waste material during the pushing process of the pushing assembly 332. In addition, both the second conveying channel 333 and the third conveying channel 334 are inclined structures. Specifically, both the second conveying channel 333 and the third conveying channel 334 have a height of one end from the ground higher than that of the other end from the ground, which can utilize the gravity to automatically transport the materials.

[0051] Furthermore, as Figure 5 and Figure 6As shown, the pushing component 332 includes a first through hole 3321 and a second through hole 3322 opened on the side of the buoyancy chamber 3312 close to the crushing component 2. The first through hole 3321 and the second through hole 3322 are respectively located on the upper and lower sides of the partition plate 3361. A first push plate 3323 and a second push plate 3324 are respectively and slidably connected through the first through hole 3321 and the second through hole 3322. The structures of the first push plate 3323 and the second push plate 3324 can both be L-shaped structures. A third cylinder 3325 and a fourth cylinder 3326 are fixedly connected inside the housing 1. The telescopic ends of the third cylinder 3325 and the fourth cylinder 3326 are respectively fixedly connected to the sides of the first push plate 3323 and the second push plate 3324 close to the crushing component 2. In the initial state, the first push plate 3323 and the second push plate 3324 are both located on the side of the buoyancy chamber 3312 close to the crushing component 2. After all the water in the buoyancy chamber 3312 is introduced into the water collection chamber 3313, the third cylinder 3325 and the fourth cylinder 3326 are started simultaneously at this time. The third cylinder 3325 pushes the first push plate 3323 to push the waste with a density less than that of water on the partition plate 3361 into one end of the third conveying channel 334, and then conveys it into the microwave sterilizer 4. And the fourth cylinder 3326 pushes the second push plate 3324 to push the waste with a density greater than that of water on the partition plate 3311 into one end of the second conveying channel 333, and then conveys it into the steam sterilizer 5.
