Description

Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and in particular to an intelligent three-phase separation treatment device for medical waste. Background Art

[0002] Medical waste refers to waste that is directly or indirectly infectious, toxic, or otherwise hazardous and is generated during the diagnosis, treatment, and nursing processes of medical institutions, including infectious waste (such as gauze, syringes), damaging waste (such as needles, scalpels), pharmaceutical waste (expired drugs), and chemical waste (such as disinfectants, mercury pollutants), etc.

[0003] This type of garbage contains a large number of pathogenic microorganisms, harmful chemicals and radioactive components. If not handled properly, it can easily cause public health problems such as hospital infections, water pollution, airborne diseases, and may even endanger human health through the food chain. Improper handling may lead to the following consequences: Biological hazards: Pathogens (such as viruses and bacteria) are transmitted through air, liquid or contact, threatening public health; Environmental pollution: Untreated medical waste leachate pollutes soil and water sources, and persistent organic pollutants (such as dioxins) are produced through incineration; Waste of resources: Mixed garbage makes recyclable materials (such as plastics and metals) unable to be reused, increasing processing costs.

[0004] Therefore, the treatment of medical waste must follow the principles of classified collection, reduction, harmlessness and resource utilization, but traditional treatment technology has significant defects: insufficient classification and manual dependence: most equipment uses a single bin for mixed collection, and no independent treatment units are designed for different types of medical waste, which can easily lead to cross-contamination. Pretreatment relies on manual sorting and delivery, exposing operators to infection risks and low efficiency; low compression and separation efficiency: traditional compression equipment is mostly a single compression chamber, relying on manual dumping of garbage, and the liquid residual rate after compression is high, resulting in leakage risks during transportation. Liquid penetration and contamination of the outer wall of the container, and transportation vehicles need to be cleaned frequently, increasing costs. The degree of automation is insufficient: most existing equipment is semi-automated. For example, compression needs to be started manually, and discharge depends on manual operation. There is a lack of intelligent monitoring and linkage control, and process interruptions occur frequently. For example, forced discharge before compression is completed causes equipment jamming or pollution leakage. Therefore, it is necessary to design a practical and intelligent intelligent three-phase separation treatment device for medical waste. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-12 The present invention provides a technical solution: an intelligent three-phase separation and treatment device for medical waste, comprising a collection box 1, At least two collecting bins 2 are arranged in parallel in the collecting box 1, and an electric door 4 controlled by a control button 3 is arranged on the top of each collecting bin 2, and a lifting isolation member 5, a side wall pushing member 6 and a bottom filter member 7 are integrated in the inside thereof from top to bottom, and a compression space 8 is formed between the lifting isolation member 5 and the bottom filter member 7; The collecting bin 2 has a closable discharge port 9 on its side wall, which is externally connected to a closable discharge box 10, a liquid collecting tank 11 and a detachable liquid collecting member 12 on its bottom, and a gas circulation member 13 including an air filter 14 connected to its side wall; The compression space 8 is provided with a garbage height sensor 15, which is linked to the lifting isolation member 5, the discharge port 9, the side wall pusher 6 and the discharge box 10; When the height of the garbage reaches a preset threshold, the lifting and isolating member 5 is triggered to move downward to compress the garbage to a predetermined height and separate the liquid into the liquid collecting tank 11, and then the side wall pushing member 6 is activated to push the compressed garbage into the discharge box 10, while the gas circulation member 13 filters the air in the bin; This device realizes efficient, safe and environmentally friendly treatment of medical waste through automated compression, liquid-gas separation, closed-loop purification and intelligent monitoring. It supports the classified collection of infectious, traumatic and drug-related medical waste and is suitable for the classified collection of medical waste in high-risk areas such as operating rooms, wards and laboratories. It is also suitable for closed environments such as cabin hospitals and mobile medical vehicles. The collection box 1 serves as the main structure of the device, providing a closed space to prevent leakage of garbage, liquid and gas, and protect internal components from external interference. At the same time, an integrated display screen is used for central control management, which is convenient for operation and monitoring. The collection bins 2 are arranged in parallel on both sides of the collection bin 1. Each bin is used independently to collect different categories of medical waste. The bin type identification is set on the upper end to facilitate classified delivery and avoid mixing. The number of collection bins 2 can be flexibly set and is not limited here. The number of collection bins 2 in this application is set to 6, which are respectively set as infectious waste bins, injury waste bins, pathological waste bins, pharmaceutical waste bins, chemical waste bins and special management waste bins. The control button 3 is used to control the switch of the electric door 4 to manage the delivery of medical waste. At the same time, it is set as a fingerprint control button to increase safety and prevent unauthorized personnel from delivering garbage. The electric door 4 is installed on the top of the collection bin 2. The switch is controlled by the control button 3 to ensure the convenience of garbage delivery. It automatically closes after delivery is completed to keep the collection bin 2 in a sealed state. The lifting isolation member 5 is installed inside the collection bin 2 to compress the garbage, reduce the volume, and improve the capacity utilization rate. It is opened after delivery is completed to put the garbage into Put it into the compression space, then close and compress it. The bottom filter element 7 filters the waste liquid in the medical waste to prevent accumulation. The filtered liquid is uniformly collected and processed through the liquid collecting tank 11 and the liquid collecting element 12. The liquid collecting element 12 collects and stores the filtered liquid for subsequent processing and replacement. The liquid collecting element 12 is detachable for easy cleaning and maintenance. The gas circulation element 13 circulates and filters the air in the collection bin 2 to keep the air clean and prevent the spread of odor and harmful gases. The gas enters from the bottom of the collection bin 2 and is discharged from the upper end after being filtered by the air filter element 14, which assists the waste liquid to circulate downward and improves the solid-liquid separation effect. The air filter element 14 efficiently filters the air, removes bacteria, viruses and odors, and ensures air quality. The garbage height sensor 15 monitors the compressed air in real time. The height of the garbage is determined by the preset threshold value, and the compression and discharge process is triggered. The side wall pusher 6 pushes the compressed garbage into the discharge box 10 for subsequent processing. The discharge port 9 connects the collection bin 2 and the discharge box 10 to transfer the compressed garbage. The discharge port 9 and the discharge box 10 are both set to a switchable mode and closed after the pushing is completed to achieve double sealing and improve the safety of garbage disposal. The discharge box 10 can be integrated with a full box reminder module and a bag sealing and sealing machine to remind relevant personnel to deal with the full load of garbage in time and seal the garbage. The full box reminder module issues an alarm, and the bag sealing and sealing machine ensures that the garbage will not leak during transportation, further improving safety. The reminder module and the bag sealing and sealing machine are both common technical means in the prior art and will not be described in detail here. Specifically, the lifting and lowering insulating member 5 comprises a lifting and lowering insulating plate 51 and an electric telescopic door 52, wherein: The isolation plate 51 is fixedly mounted on the top of the collection bin 2, and the electric telescopic door 52 is movably arranged in the isolation plate 51 to control the opening and closing of the top of the compression space; The upper end of the isolation plate 51 is provided with an inclined discharge surface 53 facing the electric telescopic door 1 52, and the isolation plate 51 is driven to rise and fall by a lifting assembly 54 to compress the garbage; The user verifies his identity through the fingerprint control button 3, triggers the electric door 4 to open, and the garbage is put into the collection bin 2 and temporarily stored in the temporary storage area between the isolation plate 51 and the electric door 4. After the garbage is put in, the electric door 4 is closed to ensure that the temporary storage area is isolated from the outside world. The temporary storage area avoids direct exposure to the compression space to reduce the risk of odor and liquid overflow. The electric door 4 and the electric telescopic door 1 52 form a double seal to ensure operational safety. The electric telescopic door 1 52 is opened, and the garbage in the temporary storage area falls freely by gravity and slides to the upper surface of the bottom filter element 7 under the guidance of the inclined discharge surface 53. The inclined discharge surface 53 optimizes the garbage sliding path to prevent material jamming or residue. After the garbage transfer is completed, the electric telescopic door 1 52 is immediately closed to ensure that the top of the compression space is sealed, and the lifting component 54 drives the isolation plate 51 to move downward, exerting pressure on the garbage and compressing it to a predetermined height; Specifically, the lifting assembly 54 includes a servo motor 541, a threaded rod 542 and a guide rod 543, and is disposed in a placement groove 21 symmetrically opened on the side wall of the collection bin 2; The servo motor 1 541 is fixedly installed in the placement slot 21 at one end, and its output end is fixedly connected to the threaded rod 542; The guide rod 543 is fixedly mounted in the placement slot 21 at the other end; A slider 544 is symmetrically fixedly installed on the side wall of the isolation plate 51 away from the electric telescopic door 1 52, the slider 544 is threadedly connected with the threaded rod 542, and the guide rod 543 is slidably matched with the slider 544; After the garbage height sensor 15 triggers a signal, the servo motor 541 drives the threaded rod 542 to rotate clockwise / counterclockwise. When the threaded rod 542 rotates forward, it drives the slider 544 to slide up along the guide rod 543, and the isolation plate 51 is lifted to make room for compression. When the threaded rod 542 rotates reversely, the slider 544 slides down, and the isolation plate 51 compresses the garbage to a preset height. The threaded rod 542 and the guide rod 543 have clear division of labor, taking into account both power transmission and motion guidance, and avoiding the jamming problem of the traditional single screw structure. Specifically, the side wall pusher 6 includes a cylinder 61 and a push cylinder 62, wherein: A push groove 22 is provided at one end of the collecting bin 2 away from the discharge port 9; The cylinder 61 is fixedly installed in the push groove 22, and its telescopic end is fixedly connected to the push cylinder 62; The push cylinder 62 is embedded in the push groove 22, and a clearance groove is provided at one end adjacent to the cylinder 61, and the cylinder 61 is accommodated in the clearance groove; The cylinder 61 provides a stable thrust to ensure that the compressed garbage can be smoothly pushed into the discharge box 10. The design of the push tube 62 being embedded in the push groove 22 saves space and avoids the protruding structure affecting the overall appearance and operation. The cylinder 61 is embedded in the give way groove of the push tube 62, which not only reduces the space occupied by the cylinder 61 in the collection bin 2, making the entire device more compact and convenient for installation and maintenance, but also extends its telescopic stroke, thereby increasing the pushing distance of the push tube 62. This ensures that the compressed garbage can be completely pushed into the discharge box 10 to avoid residue, and reduces direct contact with the external environment, preventing garbage, liquids and harmful gases from polluting and corroding the cylinder 61. Specifically, the bottom filter element 7 is a fixed structure, including a bottom plate 71 and a top plate 72 arranged on the upper end of the bottom plate through a telescopic mechanism 73, wherein: A plurality of liquid flow ports 721 are evenly distributed on the top plate 72; Two sets of independently distributed structures are provided on the bottom plate 71: Liquid flow port 2 711: evenly distributed on the bottom plate 71, corresponding to the position of liquid flow port 1 721 one by one; The puncture pins 712 are evenly distributed on the bottom plate 71 and correspond to the positions of the first liquid flow port 721 one by one, and the positions of the puncture pins 712 do not overlap with the second liquid flow port 711; The second liquid flow port 711 and the puncture pin 712 correspond to the positions of the first liquid flow port 721, respectively, so that the three are aligned in the vertical direction; The bottom filter 7 is used during the compression process: Puncture the liquid container with the puncture spike 712; The liquid is guided to flow into the liquid collecting tank 11 through the liquid flow port 1 721 and the liquid flow port 2 711; The liquid flow port 1 721 is set as evenly distributed small holes to guide the liquid to seep downward. The liquid flow port 2 711 is a hole vertically aligned with the liquid flow port 1 721 to ensure that the liquid directly flows into the liquid collection tank 11. The puncture nail 712 is a sharp protrusion evenly distributed in the gap position of the liquid flow port 2 711 to puncture the liquid container (such as an infusion bag, a blood bag) in the medical waste. The puncture nail 712 actively punctures the container to force the release of the liquid to avoid relying on natural leakage. The liquid flow port 1 721, the liquid flow port 2 711 and the puncture nail 712 are aligned in the vertical direction to form a continuous diversion path to reduce the liquid The top plate 72 is connected with the bottom plate 71 to control the lifting and lowering of the top plate 72 (for example, when compressed, it is pressed down to puncture the container, or when reset, it is raised for cleaning). When the lifting and isolating member 5 presses down the garbage, the top plate 72 is synchronously moved down by the telescopic mechanism 73, and the puncture nail 712 punctures the liquid container. The waste liquid seeps down through the liquid flow port 1 721, enters the liquid collection tank 11 through the liquid flow port 2 711, and is finally collected by the liquid collection member 12. After the compression is completed, the telescopic mechanism 73 lifts the top plate 72, and the puncture nail 712 is separated from the garbage to avoid adhesion and residue. Specifically, the telescopic mechanism 73 includes a bottom column 731, a lifting block 732 and a spring 733, wherein: The bottom column 731 is fixedly mounted at the four corners of the lower end of the top plate 72; The bottom plate 71 is provided with lifting slots at the four corners, and the lower end of the bottom column 731 extends into the lifting slot and is fixedly connected to the lifting block 732; The lifting block 732 is slidably installed in the lifting slot, and a spring 733 is fixedly installed at the lower end thereof; The spring 733 is used to buffer the relative movement between the top plate 72 and the bottom plate 71 when the isolation plate 51 descends, so as to ensure that the piercing nail 712 accurately pierces the liquid container; The isolation plate 51 is driven downward by the lifting assembly 54 to push the garbage to contact the top plate 72. After the top plate 72 is compressed, the bottom column 731 drives the lifting block 732 to move down along the lifting slot, compressing the spring 733. The spring 733 absorbs part of the pressure by deformation to avoid the rigid collision between the top plate 72 and the bottom plate 71. The top plate 72 moves downward at a uniform speed to ensure that the puncture nail 712 accurately punctures the liquid container. At the same time, the liquid flow port 1 721 and the liquid flow port 2 711 are aligned, and the liquid flows smoothly into the liquid collecting tank 11. After the compression is completed, the lifting assembly 54 drives the isolation plate 51 to rise, and the spring 733 releases the elastic force , push the lifting block 732 and the top plate 72 to reset and separate from the garbage. The spring 733 prevents the puncture pin 712 from being offset or excessively penetrated due to the downward pressure being too fast. The spring 733 of different stiffness can be selected according to the type of medical garbage (such as soft gauze or hard glass container) to adapt to different compression resistances. The sliding cooperation between the bottom column 731 and the lifting groove ensures the vertical movement of the top plate 72, and maintains the alignment of the puncture pin 712 with the liquid flow port 1 721 and the liquid flow port 2 711. When the top plate 72 is reset, the spring 733 pushes the top plate 72 to quickly separate from the garbage, reducing the adhesion of viscous liquid or debris. Specifically, the liquid collecting member 12 includes a liquid collecting box 121, a magnet 122, a liquid discharge pipe 123, a control valve 124 and a linkage button 125, wherein: The liquid collecting box 121 is detachably connected to the liquid collecting tank 11 via a magnet 122; The drain pipe 123 is fixedly installed at the lower end of the collecting bin 2, with its upper end connected to the collecting bin 2 and its lower end connected to the collecting tank 121; The control valve 124 is disposed on the drain pipe 123, and the linkage button 125 is disposed on the inner wall of the liquid collecting tank 11 and is electrically connected to the control valve 124 through a wire to control the opening and closing of the drain pipe 123; The liquid collecting box 121 is provided with a clearance opening corresponding to the liquid discharge pipe 123; During the garbage compression process, the bottom filter 7 guides the liquid to the liquid collecting tank 11, and the waste liquid flows into the liquid collecting box 121 through the drainage pipe 123 to achieve centralized collection. When the liquid collecting box 121 is adsorbed and fixed in the liquid collecting tank 11 by the magnet 122, its box structure presses the linkage button 125, and the linkage button 125 transmits an electrical signal to the control valve 124 through a wire, triggering the valve to open, and the waste liquid flows into the liquid collecting box 121 through the drainage pipe 123. When the liquid collecting box 121 is pulled out, the linkage button 125 is reset due to the loss of pressure, and the control valve 124 is automatically closed to cut off the drainage channel to prevent leakage of waste liquid. The liquid collecting box 121 can be disassembled without tools, which is convenient for cleaning and replacement. The linkage button 125 realizes the drainage pipe 123. Open and close control reduces direct contact of operators, eliminates the need for manual valve operation, simplifies processes, reduces the risk of operating errors, and avoids waste liquid leakage or environmental pollution caused by forgetting to close the valve. A liquid level sensor can be integrated in the liquid collecting box 121. When the liquid volume reaches 80% of the capacity, the control system prompts replacement to avoid overflow, or a liquid level scale line is set on the outer wall of the liquid collecting box 121 for liquid level monitoring. These are common technical means in the prior art and can be freely selected according to usage requirements. The linkage design of the liquid collecting part 12 realizes the "install and drain, remove and stop" function of waste liquid collection through mechanical triggering, magnetic fixation and automatic valve control, which significantly improves the safety and operational efficiency of medical waste treatment; Specifically, the gas circulation member 13 includes a circulation pipe 1 131, a purification chamber 132, a circulation pipe 2 133, a circulation pump 134 and a circulation pipe 3 135, which are sequentially connected to form a gas circulation path; The circulation pump 134 is embedded in the heat dissipation groove opened at the upper end of the collection box; The air filter 14 is located in the purification chamber 132 and is used to filter odors and harmful substances in the gas; After the circulation pump 134 is started, the polluted gas (including dust, pathogens, volatile organic compounds, etc.) in the collection bin 2 is drawn into the purification chamber 132 through the circulation pipe 1 131, and filtered and purified by the air filter 14. The purified clean gas is re-injected from the top of the collection bin 2 through the circulation pipe 2 133, the circulation pump 134 and the circulation pipe 3 135 to form a positive pressure environment to prevent the infiltration of external polluted air. The heat generated by the circulation pump 134 during operation is quickly discharged through the heat sink to avoid overheating of the equipment. The circulation pump 134 uses a circulation pump with a built-in frequency conversion regulation function to adapt to the gas flow requirements of different waste treatment stages (such as high-load extraction during compression and low-load maintenance during static state). The gas is recycled to reduce external emissions, which complies with environmental protection regulations for medical waste treatment. The positive pressure environment and high-efficiency filtration block the spread of pathogens and protect the safety of operators. The gas circulation part 13 realizes efficient purification and safe circulation of gas in the process of medical waste treatment through the design of closed-loop purification and dynamic adjustment, and reduces the energy consumption of the fresh air system. It is suitable for closed medical waste treatment scenarios (such as mobile cabins, isolation wards, etc.); Specifically, the air filter 14 includes a convenient pull-out plate 141 and a filter plate 143, wherein: The convenient pull-out plate 141 passes through the purification chamber 132 and extends to the outside of the side wall of the collection box 1, and a handle plate 142 is fixedly installed at the end thereof; The handle plate 142 is embedded in the side wall of the collection box 1, and a purification port corresponding to the purification chamber 132 is opened on the convenient pull-out plate 141; The filter plate 143 is detachably disposed in the purification port to filter odors and harmful substances in the gas; The polluted gas enters the purification chamber 132 from the collection bin 2 through the circulation pipe 1 131, and the gas enters the filter plate 143 through the purification port on the convenient pull-out plate 141. The filter plate 143 is configured as a multi-layer composite filter plate, which is respectively provided with a pre-filter layer: a metal mesh or foam to intercept large particles of impurities, a main filter layer: a HEPA filter to filter particles larger than 0.3 microns, an adsorption layer: an activated carbon layer to adsorb harmful gases (such as formaldehyde and hydrogen sulfide), and a sterilization layer: a photocatalyst coating to kill microorganisms. The filter plate 143 is an independent module, which is convenient for selecting filter materials according to different pollution types in the collection bin 2, and can be detachably installed in the purification port of the convenient pull-out plate 141. The purified gas enters the circulation pump 134 through the circulation pipe 2 133, and is re-injected into the collection bin 2 through the circulation pipe 3 135 after pressurization to form a cycle. The filter plate 143 can be pulled out for replacement or cleaning by pulling the convenient pull-out plate 141 through the handle plate 142 to reduce downtime; Specifically, the collection bin 2 comprises: The guide plate 23 is fixedly installed below the side wall pusher 6 to prevent the liquid from entering the circulation pipe 131 of the gas circulation part 13; The guide slope 24 is arranged at the bottom of the collecting bin 2 and is inclined toward the drain pipe 123 to guide the liquid to flow toward the liquid collecting tank 11; In the collection bin 2, liquid waste may be generated due to garbage compression or other operations.

The guide slope 24 is set at the bottom of the collection bin 2 and is inclined toward the discharge pipe 123. The liquid waste flows along the guide slope 24 under the action of gravity and finally enters the collecting tank 11 through the discharge pipe 123 to realize the centralized collection and treatment of liquid waste.
