Description

Technical Field

[0001] The utility model relates to the technical field of medical waste treatment, in particular to a medical waste collaborative disinfection device. Background Art

[0002] In the medical waste disinfection device with a built-in crusher, the high-temperature steam disinfection treatment process, microwave disinfection treatment process and friction heat disinfection treatment process are currently the most common non-incineration disinfection treatment processes for medical waste. Regardless of whether a simple high-temperature steam disinfection treatment process, microwave disinfection treatment process or friction heat disinfection treatment process is used, there are problems of long disinfection time and low treatment efficiency.

[0003] Among them, the simple high-temperature steam sterilization process is the most widely used non-incineration sterilization process, offering high reliability and zero emission of contaminated gases. However, its main problem is that steam heating can only proceed gradually from the outside in, requiring a long period of heat transfer to fully heat the medical waste inside, significantly impacting treatment efficiency. High-temperature steam sterilization devices with built-in crushers can significantly improve this problem. However, high-temperature steam sterilization devices with built-in low-speed, high-torque crushers still require heating from the outside in, as the crushed waste fragments remain stacked within the sterilization chamber. This does not fundamentally address the heating and disinfection efficiency issue. High-temperature steam sterilization devices with built-in high-speed crushers, on the other hand, face the problem of wear on the pressure vessel wall caused by the high-speed rotation of the crushed material fragments. Furthermore, the sterilized waste residue can adhere to the discharge port and door during discharge, resulting in a poorly sealed pressure vessel door. Consequently, current literature and practical applications have not yet identified a solution for high-temperature steam sterilization processes that incorporate a high-speed crusher within the pressure vessel that can generate sufficient frictional heat.

[0004] Simple microwave disinfection processes, however, are limited by the limited heating range of microwave radiation. They typically utilize an internal high-speed crusher to simultaneously pulverize and rapidly agitate the waste, ensuring that all waste passes through the microwave radiation area, evenly heating the waste and eliminating any dead spots. A major problem with this approach is that if the crusher or agitator malfunctions, unconventional measures such as spraying disinfectant are necessary to disinfect the remaining sterilized waste and equipment (such as the crusher blades) before repair can be performed, posing a significant risk of infection to operators. Furthermore, because simple microwave disinfection devices utilize non-pressurized vessels, they continuously emit large amounts of contaminated exhaust gases during the microwave disinfection process. High-efficiency filtration / adsorption devices are typically used to treat these contaminated exhaust gases before discharge. However, this can contaminate the filtration / adsorption devices, creating a new source of secondary contamination during the microwave disinfection process and necessitating regular secondary disinfection of the filtration / adsorption devices.

[0005] Simple friction heat disinfection treatment processes basically use non-pressure containers with built-in high-speed crushers. This solution has similar problems as simple microwave disinfection treatment processes.

[0006] The disinfection process of "combining microwaves and high-temperature steam" is the most efficient, safest and most reliable process known to date. The main feature of this process is the coordinated disinfection treatment method of high-temperature steam and microwaves. It takes advantage of the advantages of microwaves' strong penetration into the interior of the material and their ability to directly heat the interior, as well as the advantages of high-temperature steam's wide coverage and heating from the outside in, so that the outer surface and interior of the material are heated simultaneously, achieving the purpose of rapid disinfection and sterilization. Another major advantage of this process is that due to the use of a pressure vessel, compared to microwave disinfection treatment devices or friction heat disinfection treatments that use non-pressure vessels, no contaminated gases can be discharged during the entire disinfection process, avoiding the risk of secondary contamination caused by the discharge of contaminated gases caused by disinfection using non-pressure vessels.

[0007] From the above, it can be seen that the structure of using a high-speed crusher built into a pressure vessel has outstanding advantages, whether it is a synergistic disinfection process of high-temperature steam and frictional heat, or a synergistic disinfection process of high-temperature steam, microwave and frictional heat. However, the difficulty lies in how to give full play to the respective advantages of high-temperature steam disinfection, frictional heat disinfection and microwave radiation disinfection, and solve the key problems such as the wear of material fragments on the inner wall of the container during the operation of the high-speed crusher, the adhesion of material fragments to the inlet / outlet and inlet / out door of the pressure vessel, and the limited range of microwave radiation, resulting in the shortcomings of disinfection dead zones.

[0008] Existing literature describes high-temperature steam sterilization devices with built-in crushers in pressure vessels. For example, US Patent Publication No. 10,512,956B2 proposes a high-temperature steam sterilization system with a built-in crusher. The system includes a pressure vessel and a crusher for sterilizing medical waste. However, the patent discloses a method for discharging waste residue by rotating the entire pressure vessel and dumping it out of the feed port, using a shared inlet and outlet door. This lacks a structural design to address the adhesion of material fragments. Furthermore, the patent fails to consider a solution for protecting the inner wall of the pressure vessel once the crusher enters high-speed rotation, sufficient to generate frictional heat.

[0009] In the existing literature, there are descriptions of microwave and high-temperature steam combined disinfection and sterilization devices, each of which has its own characteristics, and some have obvious shortcomings that affect practical applications. For example, the patent with patent number ZL202022136580.0 proposes a vertical pre-crushing microwave and high-temperature steam combined disinfection treatment device, which can achieve the purpose of microwave and high-temperature steam combined disinfection and sterilization under the premise of first crushing. However, due to the following problems with this device: the crusher in the device only has a crushing function, and has no stirring function for the crushed material fragments. After the material is crushed and falls into the sterilization chamber, it will remain motionless, and there will be a dead angle for microwave radiation. It is necessary to set up another stirring device in the chamber to stir the waste fragments in the sterilization chamber or to rotate the entire chamber to solve the problem of uneven microwave distribution. Its structure is relatively complex and the cost is high.

[0010] Patent application publication number CN106670214A proposes a simple microwave treatment device with a built-in pulverizer, comprising a tank, a built-in pulverizer, and a microwave generator. Because this microwave treatment device utilizes a simple microwave treatment process, it clearly shares almost all of the aforementioned issues with typical simple microwave disinfection devices. Furthermore, it faces issues such as medical waste fragments impacting the tank's sealing performance. Installing a high-speed pulverizer within the pressure vessel of a high-temperature steam disinfection device, or within the pressure vessel of a microwave and high-temperature steam combined disinfection device, not only rapidly agitates the pulverized medical waste fragments, effectively improving the efficiency of steam heating and microwave disinfection, but also generates frictional heat, further enhancing disinfection and sterilization efficiency. While a built-in high-speed pulverizer can achieve the three functions of crushing, agitating, and generating frictional heat to heat the material, the high-speed motion of the waste fragments can damage the container's walls. While damage to the inner wall of a non-pressure vessel presents no safety hazard, persistent damage to the inner wall of a pressure vessel poses a significant safety hazard, making it unacceptable. In addition, the waste fragments splashing around in the container during the treatment process, and the discharge of waste residue fragments after treatment, will inevitably adhere to the inlet and outlet doors of the pressure vessel, making it difficult to close and seal the pressure vessel door, which is also a relatively prominent problem.

[0016] Optionally, the medical waste collaborative disinfection device further includes a microwave generator capable of irradiating microwaves on the medical waste crushed and rapidly stirred by the high-speed crusher in the space within the cabin.

[0017] Optionally, the microwave generator is installed on the outside of the pressure vessel, one or more first microwave inlets are provided on the pressure vessel, and one or more second microwave inlets are provided on the separation cabin, and the microwaves emitted by the microwave generator are introduced into the space inside the cabin through one or more first microwave inlets and one or more second microwave inlets.

[0018] Optionally, the feed hatch cover and the feed door are connected so that the feed hatch cover and the feed door open and close in a coordinated manner.

[0019] Optionally, a first feed port is provided at the top or upper side wall of the pressure vessel, the feed door is provided at the first feed port, a second feed port is provided at the top of the compartment, the feed hatch is provided at the second feed port, a first waste slag discharge port is provided at the bottom or lower side wall of the compartment, the first slag discharge door is provided at the first waste slag discharge port, a second waste slag discharge port is provided on the pressure vessel to provide a discharge channel for the waste slag discharged from the first waste slag discharge port, and the second slag discharge door is provided at the second waste slag discharge port.

[0020] Optionally, the medical waste collaborative disinfection device also includes a slag conveyor or a slag chute, the waste slag input end of the slag conveyor or the slag chute can extend into the space outside the cabin through the second waste slag discharge outlet to receive the waste slag discharged from the first waste slag discharge outlet, and the slag conveyor or the slag chute is used to output the waste slag to the outside of the pressure vessel.

[0021] Optionally, a wastewater outlet is provided at the bottom of the pressure vessel, a waste gas outlet is provided on the pressure vessel, a water inlet for inputting cooling water and / or cleaning water is provided on the pressure vessel, and the waste gas outlet and the steam inlet are the same interface or different interfaces.

[0022] The utility model has the following features:

[0023] The use of a pressure vessel as the tank avoids the problem of the non-pressure vessel used in common microwave-only or friction-only disinfection devices, which requires continuous exhaust of the contaminated gases (including contaminated steam) generated during the treatment process. A compartment is also provided within the pressure vessel, keeping the medical waste contained throughout the disinfection and sterilization process. During high-speed crusher operation, the churning of medical waste fragments is confined within the compartment, preventing them from damaging the inner walls of the pressure vessel or sensors within it. They also avoid adhering to the feed door and the first feed port, potentially compromising their sealing. They also avoid adhering to the second waste discharge port and the second discharge door, potentially compromising their sealing.

[0024] The waste slag after disinfection and sterilization can be discharged to the outside of the pressure vessel through the first waste slag discharge outlet and the second waste slag discharge outlet, which can prevent the waste slag fragments from adhering to the second slag discharge door of the pressure vessel during the slag discharge process, thereby preventing the waste slag fragments from adversely affecting the sealing performance of the second slag discharge door.

[0025] The first feed port and the first waste residue discharge port are arranged separately, and the second feed port and the second waste residue discharge port are arranged separately, so that the loading and discharging of medical waste are more convenient.

[0026] A slag conveyor or slag chute is provided. During the discharging process, when the first slag discharge door is opened and the waste slag of medical waste falls out, it can directly fall into the slag discharge conveyor or slag discharge chute and be sent out of the disinfection device through the slag discharge conveyor or slag discharge chute, thereby preventing the waste slag from falling into the disinfection device and adhering to the second waste slag discharge outlet when being removed, thereby affecting the normal closing and sealing of the second slag discharge door and the second waste slag discharge outlet.

[0027] Through the above-mentioned innovative design, the utility model successfully solves the problem that when the built-in high-speed crusher is running at high speed, the material fragments stirred at high speed after crushing damage the inner wall of the pressure vessel, and the fragments adhere to the feed port / door and discharge port / door, resulting in the feed door or discharge door on the pressure vessel not closing tightly, making it difficult to discharge the waste residue.

[0028] A high-speed crusher (typically rotating at 800-2000 rpm) shreds and rapidly agitates the medical waste within the compartment. Friction between the blades, the materials themselves, and the compartment walls generates frictional heat, rapidly heating the waste. This also allows high-temperature steam and microwaves to more effectively heat and disinfect the rapidly agitated fragments. This design leverages the synergistic heating advantages of frictional heat, microwaves, and high-temperature steam, effectively improving sterilization efficiency and achieving rapid disinfection and sterilization of medical waste.

[0035] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0037] like Figure 1 A medical waste collaborative disinfection device shown in the figure includes a pressure vessel 1 and a high-speed crusher 3. A partition cabin 2 is provided in the pressure vessel 1, and the partition cabin 2 divides the inner cavity of the pressure vessel 1 into an inner cabin space 203 located inside the partition cabin 2 and an outer cabin space 103 located outside the partition cabin 2. The inner cabin space 203 is used to accommodate medical waste. An openable and closable feed door 102 is provided on the upper side wall or top of the pressure vessel 1, and an openable and closable feed hatch cover 202 is provided on the upper part of the partition cabin 2. A first openable and closable slag discharge door 205 is provided on the bottom or lower side wall of the partition cabin 2, and an openable and closable second slag discharge door 110 is provided on the bottom or side wall of the pressure vessel 1. The position of the second slag discharge door 110 is lower than the bottom of the partition cabin 2. The high-speed crusher 3 is configured to crush the medical waste in the inner cabin space 203; a steam inlet 105 is provided on the pressure vessel 1, and a steam channel connecting the inner cabin space 203 and the outer cabin space 103 is provided on the partition cabin 2.

[0038] The above-mentioned medical waste collaborative disinfection device is used to separate the area in the pressure vessel 1 from other areas by providing a partition chamber 2 inside the pressure vessel 1. The partition chamber 2 is used to form an independent internal space 203, and the medical waste is loaded in the internal space 203. The medical waste is confined to the partition chamber 2, which can effectively prevent the medical waste from splashing and overflowing into the external space 103 outside the partition chamber 2 during the high-speed crushing process. When the high-speed crusher 3 is running, the medical waste fragments stirred at high speed are confined to the partition chamber 2, so that the medical waste fragments will neither damage the inner wall of the pressure vessel 1 nor the sensors inside the pressure vessel 1, nor will they adhere to the feed door 102 and the second slag discharge door 110 of the pressure vessel 1. This can prevent the medical waste fragments from adversely affecting the sealing performance of the feed door 102 and the second slag discharge door 110, allowing the pressure vessel 1 to better achieve and maintain high pressure inside, thereby ensuring the heating effect on the medical waste and achieving rapid disinfection and sterilization of the medical waste.

[0039] In the aforementioned medical waste collaborative disinfection device, steam inlet 105 allows high-temperature steam to be introduced into the external space 103. The high-temperature steam in external space 103 can then enter the internal space 203 through the steam passage. High-speed crusher 3 crushes and agitates the medical waste within compartment 2, allowing the high-temperature steam to more fully act on the medical waste within the compartment after being crushed by the high-speed crusher. This allows the high-temperature steam to heat and disinfect the entire pressure vessel interior and the medical waste. This design fully leverages the synergistic disinfection advantages of frictional heat and high-temperature steam, effectively improving sterilization efficiency and achieving rapid disinfection and sterilization of medical waste.

[0040] The combination of high-temperature steam, high-speed crusher 3, and pressure vessel 1 can solve the problem of a simple microwave disinfection and sterilization device where a failure of the high-speed crusher 3 or agitator requires emergency disinfection of unsterilized waste and devices such as the blades of the high-speed crusher 3 before repairs can be performed, which poses a high risk of infection to operators. Furthermore, the problem of a simple microwave disinfection device continuously discharging a large amount of bacteria-laden exhaust gas during the microwave disinfection process, necessitating the addition of an exhaust gas treatment device, which creates new secondary pollution during the microwave disinfection process.

[0041] In some embodiments, the steam passage includes holes and / or gaps provided on the compartment 2. In a specific implementation, the holes and / or gaps may be provided on the top and / or side walls and / or bottom of the compartment 2. As a preferred example, the holes and / or gaps are provided on the top of the compartment 2, and the holes and / or gaps on the compartment 2 are utilized to connect the cabin interior space 203 and the cabin exterior space 103, thereby reducing the possibility of high-speed churning medical waste fragments clogging the steam passage. In a specific implementation, the holes on the compartment top may be provided on the feed hatch cover 202, and the gaps on the compartment top may be provided between the feed hatch cover 202 and the compartment body 201.

[0042] In some embodiments, the high-speed crusher 3 includes a crushing blade 303 and an electric drive assembly for driving the crushing blade 303 to rotate. The crushing blade 303 is disposed at the bottom of the cabin space 203. Placing the crushing blade 303 at the bottom of the cabin space 203 of the compartment 2 and using the electric drive assembly to drive the crushing blade 303 to rotate not only breaks the medical waste in the cabin space 203 into small fragments, but also stirs the medical waste fragments in the cabin space 203, allowing microwaves and high-temperature steam to fully contact the medical waste fragments, fully leveraging the synergistic disinfection advantages of microwaves and high-temperature steam to achieve rapid disinfection and sterilization of medical waste.

[0043] In some embodiments, the electric drive assembly includes a drive motor 301 and a transmission mechanism 302. The drive motor 301 is disposed outside the pressure vessel 1, and the transmission mechanism 302 is connected between the drive motor 301 and the crushing blade 303. As a specific example, the crushing blade 303 can be mounted on the bottom wall of the compartment 2 via a blade shaft and bearings. The drive motor 301 can be fixedly connected to the bottom side of the pressure vessel 1, and the transmission mechanism 302 can be a transmission shaft connected between the power output end of the drive motor 301 and the blade shaft.

[0044] In specific implementation, by selecting a high-speed drive motor 301 to drive the crushing blade 303 to operate at high speed, high-speed crushing and rapid stirring can be achieved. The speed of the crushing blade 303 of the high-speed crusher 3 is usually around 800-2000 rpm, while the speed of an ordinary low-speed crusher is usually below 30 rpm.

[0045] Regarding the speed setting of the high-speed crusher 3, generally, the higher the speed, the greater the frictional heat generated and the greater the wear on the container wall; the lower the speed, the less frictional heat generated and the less wear on the container wall. The present invention, by providing a compartment 2 within the pressure vessel 1, allows the speed of the high-speed crusher 3 to be set higher, which helps improve the crushing and agitation effect of medical waste and also generates more frictional heat. In specific implementations, the speed of the high-speed crusher can be set to no less than 1200 rpm.

[0046] In some embodiments, the medical waste collaborative disinfection device further includes a microwave generator 4 capable of irradiating the medical waste crushed and rapidly agitated by the high-speed crusher 3 within the chamber space 203 with microwave radiation. The coordinated operation of high-temperature steam, the high-speed crusher 3, the microwave generator 4, and the pressure vessel 1 fully leverages the advantages of frictional heat, microwaves, and high-temperature steam for synergistic heating, effectively improving sterilization efficiency and achieving rapid disinfection and sterilization of medical waste. The combined disinfection process of frictional heat, microwaves, and high-temperature steam proposed in this utility model can shorten the disinfection time of medical waste to approximately 5 minutes, significantly reducing the disinfection and sterilization time required by high-temperature steam, frictional heat, or microwave disinfection processes alone.

[0047] In some embodiments, microwave generator 4 is installed outside pressure vessel 1. Pressure vessel 1 is provided with one or more first microwave inlets 108, and compartment 2 is provided with one or more second microwave inlets. Microwaves emitted by microwave generator 4 are introduced into compartment space 203 via one or more first microwave inlets 108 and one or more second microwave inlets. In a specific implementation, multiple microwave generators 4 may be installed outside the sidewall of pressure vessel 1, with corresponding multiple first microwave inlets 108 and multiple second microwave inlets.

[0048] In some embodiments, the feed hatch cover 202 is connected to the feed door 102 so that the feed hatch cover 202 and the feed door 102 are opened and closed in a linked manner. By arranging the feed hatch cover 202 and the feed door 102 that are opened and closed in a linked manner, it is convenient to load medical waste. During specific implementation, the feed hatch cover 202 can be fixedly connected to the feed door 102 to realize linked opening and closing, and the feed hatch cover 202 and the feed door 102 can also be connected by a linked door opening mechanism to realize linked opening and closing. In other embodiments, the feed hatch cover 202 can also be arranged beside the feed door 102, and feeding can be completed by successively opening and closing the feed door 102 and the feed hatch cover 202.

The above-mentioned technical solution, with the separate provision of the first feed port and the first waste residue discharge port 204, and the separate provision of the second feed port and the second waste residue discharge port 109, facilitates the loading and unloading of medical waste and helps prevent medical waste fragments from adhering to the feed door 102 and the second slag discharge door 110 of the pressure vessel 1.

[0050] In some embodiments, the medical waste collaborative disinfection device also includes a slag conveyor 5 or a slag chute. The slag input end of the slag conveyor 5 or the slag chute can extend into the extravehicular space 103 through the second slag discharge port 109 to receive the slag discharged from the first slag discharge port 204. The slag conveyor 5 or the slag chute is used to output the slag to the outside of the pressure vessel 1. Using the above technical solution, the second slag discharge port 109 is set on the side wall of the pressure vessel 1. The laterally arranged second slag discharge port 109 provides convenience for using the slag conveyor 5 or the slag chute to discharge the slag, and can discharge the slag more conveniently. The waste slag after disinfection and sterilization is discharged to the outside of the pressure vessel 1 through the first slag discharge port 204 and the second slag discharge port 109, which can prevent the slag fragments from adhering to the second slag discharge door 110 of the pressure vessel 1 and prevent the medical waste fragments from adversely affecting the sealing performance of the second slag discharge door 110. As a preferred example, the second waste slag discharge port 109 is provided on the side wall of the pressure vessel 1 , which can facilitate the use of the slag conveyor 5 or the slag chute.

[0051] As a specific example, the slag conveyor 5 includes a housing, a waste slag conveying mechanism disposed within the housing, and a motor for driving the waste slag conveying mechanism. The housing is provided with a waste slag inlet 501 and a waste slag outlet 502. The motor drives the waste slag conveying mechanism to convey the waste slag at the waste slag inlet 501 to the waste slag outlet 502. In a specific implementation, the waste slag conveying mechanism can be a screw conveying mechanism, and the slag conveyor 5 can be mounted on a cart 6 to facilitate movement of the slag conveyor 5.

[0052] In some embodiments, a wastewater outlet 107 is provided at the bottom of the pressure vessel 1 , and the wastewater outlet 107 is used to discharge wastewater in the pressure vessel 1 .

[0053] In some embodiments, the pressure vessel 1 is provided with an exhaust gas outlet 104. The exhaust gas outlet 104 is used to discharge exhaust gas from the pressure vessel 1 and can be provided on the top wall or side wall of the pressure vessel 1. In a specific implementation, the exhaust gas outlet 104 and the steam inlet 105 are the same interface or different interfaces, that is, the steam inlet 105 and the exhaust gas outlet 104 can be two separate interfaces or combined into one interface.

[0054] In some embodiments, the pressure vessel 1 is provided with a water inlet 106 for inputting cooling water and / or cleaning water. The water inlet 106 can be provided on the top wall or side wall of the pressure vessel 1 and is connected to a cooling water spraying device and / or a cleaning water spraying device within the pressure vessel 1.

[0055] As a specific example, the pressure vessel 1 includes a pressure vessel body 101 with an open top and a plurality of legs 111 connected to the bottom of the pressure vessel body 101. The open top of the pressure vessel body 101 is the first feed port, a wastewater outlet 107, a steam inlet 105, and an exhaust gas outlet 104 are provided on the pressure vessel body 101, a water inlet 106 is provided on the feed door 102, a second waste residue outlet 109 is provided on the side wall of the pressure vessel body 101, a second residue outlet 110 is used to open or close the second residue outlet 109, and the feed door 102 is used to open or close the first feed port. When the feed door 102 and the second residue outlet 110 are closed, the feed door 102, the second residue outlet 110, and the pressure vessel body 101 form a sealed inner cavity. In a specific implementation, the feed door 102 and the second residue outlet 110 can be quick-opening doors.

[0056] In a specific implementation, the compartment 2 can be an independent container disposed inside the pressure vessel 1.

The compartment 2 can also be surrounded by a partition plate disposed inside the pressure vessel 1 and a portion of the container wall of the pressure vessel 1.

[0057] As a specific example, the compartment 2 is an independent container disposed within the pressure vessel 1. The compartment 2 further includes a compartment body 201 with an upper opening. The upper opening of the compartment body 201 serves as a second feed inlet. A first waste slag discharge outlet 204 is disposed at the lower portion of the bottom wall or side wall of the compartment body 201. A feed hatch 202 is used to open or close the second feed inlet, and a first slag discharge door 205 is used to open or close the first waste slag discharge outlet 204.
