Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, specifically to a medical waste pretreatment system. Background Technology

[0002] Medical waste refers to infectious, toxic, and other hazardous waste generated by medical and health institutions during medical treatment, prevention, and healthcare activities. According to relevant requirements, medical waste should be centrally disposed of in a harmless manner. However, due to the dispersed nature of medical waste in both time and space, centralized collection and transportation are challenging, and medical institutions generally face the need to collect and temporarily store it. During the collection and temporary storage process, problems often arise such as difficulties in sorting and a lack of sufficient space and equipment for storage.

[0003] Medical waste, primarily consisting of disposable medical supplies such as syringes and infusion sets, and fabrics like drapes and dressings contaminated with patient bodily fluids, carries a large number of pathogenic microorganisms. During collection, packaging, and storage, these wastes pose a risk of transmitting infectious diseases to staff. Furthermore, the accumulation of this infectious waste creates numerous cavities within the pile, significantly increasing the space required for temporary storage.

[0004] Furthermore, sharps waste such as needles, guidewires, ampoules, and glass slides pose a risk of puncture or cut to workers. Weight-based charging is a widely used method for the centralized collection and disposal of medical waste. Sharps waste, primarily composed of metals and glass, is a misplaced resource; after proper treatment, it can be recycled, reducing disposal costs and generating greater value. Utility Model Content

Compared with the prior art, the advantages of this utility model are: 1. The medical waste pretreatment system of this utility model achieves efficient crushing of medical waste by setting the crusher above the feed end of the first conveying mechanism, setting the eccentric magnetic roller at the discharge end of the first conveying mechanism, and then setting the metal buffer mechanism, air separator, glass temporary storage hopper and light fragment buffer mechanism below the discharge end of the first conveying mechanism in sequence; by utilizing the high-frequency alternating magnetic field provided by the eccentric magnetic roller, combined with the conductivity of metal, the metal fragments in the mixture are induced to generate current through electromagnetic induction, and are repulsed in the magnetic field, so that the metal waste jumps and separates from the discharge end of the first conveying mechanism along the conveying direction into the metal buffer mechanism; By directing the air separator's outlet towards the discharge end of the first conveying mechanism, the air force provided by the air separator allows lightweight fragments to be blown into the lightweight fragment buffer mechanism.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0013] In the description of this utility model, it should be understood that the terms "side", "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0015] Example like Figure 1 and Figure 4As shown, the medical waste pretreatment system of this utility model includes: a crusher 1, a first conveying mechanism 2, an eccentric magnetic roller 3, an air separator 5, a glass temporary storage hopper 8, a metal buffer mechanism, a lightweight fragment buffer mechanism, and an ultraviolet disinfection and packaging mechanism. The crusher 1 is located above the feed end of the first conveying mechanism 2. Medical waste is fed into the crusher 1 and is crushed, sheared, and broken into finely crushed mixed materials. The components of the medical waste include plastics, rubber, fibers, glass (soda-lime glass, borosilicate glass), and metals (stainless steel). The first conveying mechanism 2 uses a belt conveyor; the finely crushed mixed materials fall onto the conveyor belt and are conveyed to the discharge end. The eccentric magnetic roller 3 is located at the discharge end of the first conveying mechanism 2. The metal buffer mechanism, air separator 5, glass temporary storage hopper 8, and lightweight fragment buffer mechanism are sequentially located below the discharge end of the first conveying mechanism 2. The metal buffer mechanism is located in front of the discharge end of the first conveyor 2. When the fine mixed material is conveyed on the first conveyor 2, there is a forward force, so the glass storage hopper 8 is located directly below and slightly forward of the discharge end of the first conveyor 2. The lightweight waste buffer mechanism is located behind the discharge end of the first conveyor 2. The eccentric magnetic roller 3 provides a high-frequency alternating magnetic field. Based on the conductivity of metal, the metal waste is subjected to a repulsive force in the magnetic field, thus collecting the metal waste into the metal buffer mechanism. The air outlet of the air classifier 5 faces the discharge end of the first conveyor 2 to blow the lightweight waste into the lightweight waste buffer mechanism. The glass storage hopper 8 collects the glass waste that falls from the discharge end of the first conveyor 2 due to gravity. In practice, fine materials other than metal fall from the discharge end of the conveyor belt. After being separated by compressed air, the less dense plastic, rubber, and fiber fragments are blown into the lightweight waste buffer mechanism, while the denser glass fragments fall naturally into the glass storage hopper 8. The discharge ends of the metal buffer mechanism, the glass temporary storage hopper 8, and the lightweight fragment buffer mechanism are all connected to the ultraviolet disinfection and packaging mechanism, which is used to achieve independent packaging and disinfection of sorted medical waste. In this embodiment, by placing the crusher 1 above the feed end of the first conveying mechanism 2, efficient crushing of medical waste is achieved. An eccentric magnetic roller 3 is positioned at the discharge end of the first conveying mechanism 2. A metal buffer mechanism, an air separator 5, a glass storage hopper 8, and a lightweight waste buffer mechanism are sequentially positioned below the discharge end of the first conveying mechanism 2. Utilizing the high-frequency alternating magnetic field provided by the eccentric magnetic roller 3, combined with the conductive properties of metal, electromagnetic induction induces a current in the metal fragments in the mixture. These fragments are repelled in the magnetic field, causing the metal waste to jump and separate from the discharge end of the first conveying mechanism 2 along the conveying direction into the metal buffer mechanism. With the air separator 5's outlet facing the discharge end of the first conveying mechanism 2, the air force provided by the air separator 5 blows the lightweight waste into the lightweight waste buffer mechanism. Glass waste in the mixed waste falls from the discharge end of the first conveying mechanism 2 into the metal buffer mechanism due to gravity. Thus, medical waste is classified according to material. Finally, the discharge ends of the metal buffer mechanism, the glass temporary storage hopper 8, and the lightweight fragment buffer mechanism are all connected to the ultraviolet disinfection and packaging mechanism. This enables the independent packaging and disinfection of sorted medical waste, reduces the risk of medical waste causing harm to staff, and significantly improves the efficiency of medical waste collection, storage, and management.

[0016] like Figure 1 As shown, the metal buffer mechanism includes a metal storage hopper 4, an eddy current sterilization component 6, and a metal storage hopper 7. The metal storage hopper 4 is located in front of the discharge end of the first conveying mechanism 2. The eddy current sterilization component 6 surrounds the outside of the metal storage hopper 4. The eddy current sterilization component 6 uses a coil carrying high-frequency alternating current to generate a high-frequency alternating magnetic field, causing strong eddy currents in the metal scrap. Under the action of the current heating effect, high heat is released from the inside to the outside, killing pathogenic microorganisms in the scrap. The metal storage hopper 7 is located below the metal storage hopper 4 to hold the sterilized metal scrap inside the metal storage hopper 4. The discharge end of the metal storage hopper 7 is connected to the ultraviolet sterilization and packaging mechanism.

[0017] like Figure 1 As shown, the lightweight scrap buffer mechanism includes a lightweight scrap sorting hopper 9, a compression conveying assembly, and a scrap temporary storage hopper 15. The lightweight scrap sorting hopper 9 is located behind the discharge end of the first conveying mechanism 2. The air classifier 5 blows low-density plastic, rubber, and fiber scraps into the lightweight scrap sorting hopper 9. The feed end of the compression conveying assembly is connected to the lightweight scrap sorting hopper 9, and the discharge end of the compression conveying assembly is connected to the scrap temporary storage hopper 15. The compression conveying assembly is used to compress and compact the lightweight scrap before conveying it to the scrap temporary storage hopper 15. The discharge end of the scrap temporary storage hopper 15 is connected to the ultraviolet sterilization and packaging mechanism.

[0018] like Figure 1As shown, the upper part of the lightweight waste sorting hopper 9 is equipped with an atomizing nozzle 10. By spraying an appropriate amount of water mist through the atomizing nozzle 10, the lightweight waste is moistened, which can enhance the effect of subsequent microwave sterilization.

[0019] like Figure 1 As shown, the compression conveying assembly includes a screw conveyor mechanism 12. The screw conveyor mechanism 12 includes a conveying screw 13. The feed end of the screw conveyor mechanism 12 is connected to the discharge end of the lightweight crushed material sorting hopper 9, and the discharge end of the screw conveyor mechanism 12 extends to connect with the feed end of the crushed material temporary storage hopper 15.

[0020] Furthermore, a gas collecting pipe 14 is provided inside the screw conveyor mechanism 12. The gas collecting pipe 14 extends through to the outside of the screw conveyor mechanism 12 and connects to the waste gas treatment mechanism. The gas collecting pipe 14 is used to collect gas so that the waste gas generated inside the screw conveyor mechanism 12 can be transported to the waste gas treatment mechanism. In other embodiments, the shaft of the conveying screw 13 can be set as a hollow structure, with an air inlet at the end of the shaft near the outlet end of the screw conveyor mechanism 12, and the other end of the shaft extends to the outside of the screw conveyor mechanism 12 and is connected to the waste gas treatment mechanism through a pipe.

[0021] like Figure 1 As shown, the conveying screw 13 is a variable pitch conical conveying screw. From the inlet to the outlet of the conveying screw 13, the radial cross-sectional area of ​​the conveying screw 13 gradually decreases, and the screw pitch gradually decreases. During the conveying process of lightweight crushed materials in the variable pitch conical screw, as the volume becomes smaller closer to the outlet, the cavities between the crushed materials are gradually compressed, becoming compact and dense, thus reducing the required storage space.

[0022] Furthermore, a microwave generator 11 is installed within the screw conveyor mechanism 12. Specifically, the microwave generator 11 is arranged around the outer periphery of the variable-pitch conical conveying screw, using microwaves to rapidly heat the moist lightweight scrap inside the screw, killing pathogenic microorganisms therein. Water vapor generated during the conveying of the lightweight scrap and air squeezed out of the cavity after compression are discharged from the exhaust port of the gas collecting pipe 14 to the waste gas treatment mechanism. After being disinfected and compressed, the lightweight scrap is discharged from the outlet of the variable-pitch conical screw to the scrap temporary storage hopper 15, and then enters the ultraviolet disinfection and packaging mechanism.

[0023] like Figure 2 As shown, the waste gas treatment mechanism includes a purification chamber 16 and an exhaust fan 18. Activated carbon 17 is installed inside the purification chamber 16; the gas collection pipe 14 is connected to the air inlet of the purification chamber 16 via a pipe, and the exhaust fan 18 is connected to the air outlet of the purification chamber 16. Under the action of the exhaust fan 18, the waste gas generated in the spiral conveying mechanism 12 is transported to the purification chamber 16, purified by the activated carbon 17, and then discharged.

[0024] like Figure 3As shown, the ultraviolet disinfection packaging mechanism comprises a second conveying mechanism 20, a material level detector 21, a packaging box 22, a glue-injection packaging machine 24 and a disinfection bin 25. The second conveying mechanism 20 may specifically be a belt conveyor, and the packaging box 22 is configured to hold sorted medical waste. The discharge ends of the second metal temporary storage hopper 7, the glass temporary storage hopper 8 and the crushed material temporary storage hopper 15 are all arranged above the second conveying mechanism 20, and control valves 23 are arranged at the discharge ends of the second metal temporary storage hopper 7, the glass temporary storage hopper 8 and the crushed material temporary storage hopper 15. Material level detectors 21 are arranged at sides of the discharge ends of the second metal temporary storage hopper 7, the glass temporary storage hopper 8 and the crushed material temporary storage hopper 15, and both the material level detectors 21 and the control valves 23 are connected to a remote control system for linkage control. The material level detector 21 may specifically be a radar detection sensor. The material level detector 21 is configured to detect the material level height in the packaging box 22 in real time. When a preset loading capacity is reached, the control valve 23 at the discharge end of the temporary storage hopper is closed to stop discharging, and the second conveying mechanism 20 is controlled to transmit the packaging box 22 to the position of the glue-injection packaging machine 24. The glue-injection packaging machine 24 and the disinfection bin 25 are sequentially arranged at the side of the second conveying mechanism 20 along the conveying direction of the packaging box 22. The glue-injection packaging machine 24 is configured to package the packaging box 22, and the specific structural arrangement of the glue-injection packaging machine 24 may adopt conventional arrangements in the art, which will not be repeated herein. An ultraviolet generator 26 is arranged in the disinfection bin 25, so as to completely seal the packaging box 22 and disinfect the medical waste in the packaging box 22.

[0025] In this embodiment, the crushed material processed in the front-end temporary storage hopper falls into the open packaging box 22. After the packaging material level is reached, the control valve 23 on the discharge opening of the temporary storage hopper is closed, the packaging box 22 is conveyed to the position where the glue-injection packaging machine 24 is located, UV glue (ultraviolet photosensitive glue) is injected into the joint of the packaging box 22 and the box cover is closed. Then the whole is conveyed into the disinfection bin 25, the UV glue is cured under the irradiation of ultraviolet light, and the packaging box 22 is completely sealed. The packaging box 22 and the box cover are made of materials with high ultraviolet transmittance (such as PMMA and other acrylates), ultraviolet light can disinfect the surface of the box body, and penetrate the box body to disinfect the surface of the crushed waste inside. Medical glass includes soda-lime glass and borosilicate glass, which also have good ultraviolet transmittance, so the crushed glass can be directly disinfected in the disinfection bin 25. The completely disinfected and packaged packaging box 22 is conveyed out of the system.

[0026] The integrated pretreatment system in this embodiment can be used for simple pretreatment of on-site disinfection and packaging of medical waste at generation sources such as hospitals and clinics, which effectively reduces the risk of harm to staff, facilitates on-site collection, temporary storage and subsequent transfer, and provides more possibilities for resource disposal.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
