Description

Technical Field

[0001] This invention relates to the technical field of medical waste treatment, and in particular to a medical waste treatment container and a medical waste treatment method. Background Technology

[0002] Medical waste, generally referring to medical solid waste, is solid waste generated by medical and health institutions, medical research units, and medical teaching institutions during medical activities, medical research, teaching experiments, and other related activities. It possesses infectious, toxic, harmful, or other hazardous properties and requires collection, storage, transportation, and treatment according to specific regulations. Medical waste contains harmful microorganisms and chemical pollutants, and improper handling can easily pose environmental infection risks; therefore, it must be rendered harmless using specialized equipment.

[0003] In existing technologies, the treatment and transportation of medical waste are mostly achieved through manual operation or simple conveying structures. First, the waste to be sterilized is placed into a sterilization container; after the sterilization process is completed, it is collected and processed collectively. From a practical application perspective, existing technologies have certain shortcomings. On the one hand, the equipment for sterilization, crushing / compression, and transportation is set up independently, resulting in low overall integration and insufficient coordination between processing stages, affecting the overall efficiency of medical waste treatment. On the other hand, the transportation of medical waste requires manual intervention.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0026] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sterilization chamber 1a serves as a high-temperature, low-pressure sterilization site for medical waste and is an important container to ensure the harmlessness of medical waste. It is used to create a high-temperature, low-pressure environment to kill pathogenic microorganisms that may be present in the waste. The crushing and compression unit 2a is used for subsequent processing of sterilized medical waste. First, the sterilized waste is crushed into particles of uniform size to destroy the shape of the medical waste, and then it is further compressed into blocks to reduce the volume of waste. At the same time, the moisture accumulated after high-temperature steam treatment is removed, reducing the difficulty of subsequent storage and transportation. The transfer unit 3a is located between the sterilization chamber 1a and the crushing and compression unit 2a, and is responsible for transferring medical waste between the two units. It needs to send the medical waste to be sterilized into the sterilization chamber 1a, and also transfer the waste from the sterilization chamber 1a to the crushing and compression unit 2a after sterilization, so as to realize the connection of the processing flow. The steam supply unit 4a is connected to the sterilization chamber 1a. Its functions are as follows: first, to provide steam to the steam jet pump, so that the steam jet pump can evacuate the sterilization chamber and improve the penetration ability of steam for subsequent sterilization; second, to provide sufficient steam to the sterilization chamber 1a, so as to create an environment that meets the requirements of high temperature and high pressure sterilization within the sterilization chamber 1a, ensuring the sterilization effect. The waste gas treatment unit 5a manages the waste gas generated in the entire processing process, forming a complete process from waste gas collection, treatment to final emission, avoiding the direct emission of harmful gases and the impact on the environment.

[0028] The medical waste treatment unit also includes a wastewater treatment unit, which collects the drainage pipes of various equipment and merges them into one channel. The wastewater is then discharged after secondary sterilization by an ultraviolet sterilizer.

[0029] Through the coordinated operation of the above-mentioned units, this modular unit can realize the entire process of medical waste treatment from delivery to harmless treatment and compliant discharge of exhaust gas and wastewater. The units have clear division of labor and are interconnected, providing a structural foundation for the efficient treatment of medical waste and solving the problems of decentralized links and low degree of automation in traditional treatment methods.

[0030] like Figure 1 As shown, the container includes a platform that extends in the left and right direction with a certain extension length. The steam supply unit 4a and the exhaust gas treatment unit 5a are arranged side by side at the left end of the platform, the crushing and compression unit 2a is at the right end of the platform, and the transfer unit 3a is arranged between the sterilization chamber 1a and the crushing and compression unit 2a.

[0031] To ensure the sterilization chamber 1a can stably and efficiently complete high-temperature and high-pressure sterilization, its structural design must meet the requirements of sealing, media transportation, and discharge during the sterilization process. The sterilization chamber 1a includes a support base 11a, a sterilization chamber body 12a, a sterilization chamber door 13a, and steam inlet, vacuum outlet, and drain outlet located on the sterilization chamber body 12a. The support base 11a is fixed to the ground to provide stable support for the sterilization chamber body 12a, preventing displacement due to pressure changes or its own weight during sterilization and ensuring the safety of the sterilization process. The sterilization chamber body 12a is designed as a double-layered hollow tank with an external insulation layer. This double-layered structure reduces heat exchange between the interior and exterior of the sterilization chamber body 12a, helping to maintain the required temperature environment for sterilization. The axis of the sterilization chamber body 12a extends along the moving direction of the hopper 31c, and one side of its axis is provided with a steam inlet facing the transfer unit 3a. The sterilization hatch provides a passage for the entry and exit of medical waste. The sterilization door 13a is hinged to the end of the sterilization chamber 12a with the sterilization hatch and is opened and closed by a cylinder. The cylinder drive ensures the smoothness and sealing of the opening and closing process of the sterilization door 13a. The sterilization door is a pressure vessel quick-opening door structure. Two cylinders drive the locking ring and the sterilization door respectively. After the sterilization door is closed, the cylinder drives the locking ring to close tightly to ensure the sealing requirements. When the sterilization door 13a is closed, it can form a sealed space with the sterilization chamber 12a, which meets the sealing requirements of the sterilization chamber 12a for high temperature and high pressure sterilization.

[0032] In addition, the steam inlet on the sterilization chamber 12a is used to receive steam supplied by the steam supply unit 4a and evenly distribute the steam into the interior of the sterilization chamber 12a; the vacuum port is used to evacuate the sterilization chamber; and the drain port is used to discharge condensate, spray wastewater, or wastewater generated during the sterilization process. This structural design enables the sterilization chamber 1a to meet the core functional requirements of high-temperature and high-pressure sterilization while also achieving the orderly transport and discharge of the media, ensuring the stability and efficiency of the sterilization process.

[0033] The crushing and compression unit 2a, as a key component in the reduction and treatment of medical waste, is structurally designed to adapt to the physical characteristics of sterilized waste, ensuring smooth crushing and compression processes. The crushing and compression unit 2a includes a frame, a crusher 200a, and a compressor 300a. The compressor 300a contains a compression pusher plate. The frame is fixedly mounted on a platform, serving as the mounting base for the crusher 200a and compressor 300a. The stable support of the frame prevents displacement due to vibration during operation, ensuring the stability of the crushing and compression operations. The crusher 200a, mounted on the frame, crushes the high-temperature, high-pressure sterilized medical waste into granules. It is a twin-shaft crusher. The discharge gate of the compressor 300a is linked to a hydraulic cylinder. During compression, the inlet of the compression chamber is closed simultaneously. After compression, the discharge gate opens, and the hydraulic cylinder continues to push the compression pusher plate to discharge the waste.

[0034] The function of the transfer unit 3a is to automate the transfer of medical waste between the sterilization chamber 1a and the crushing and compression unit 2a. The transfer unit 3a includes a lifting structure 31a, a horizontal drive structure 31b, and a hopper 31c.

[0035] The lifting structure 31a is located between the sterilization chamber 12a and the crusher 200a. The lifting structure 31a is a scissor type structure with stable lifting stroke and strong load-bearing capacity. It can realize the lifting action through hydraulic drive and provide power for the height adjustment of the hopper 31c.

[0036] A horizontal drive structure 31b is mounted on the lifting structure 31a and is used to drive the hopper 31c to move horizontally, allowing the hopper 31c to adjust its position in the horizontal direction to match the horizontal distance between the sterilization chamber opening of the sterilization chamber 1a and the feed end of the crusher 200a. The horizontal drive structure 31b drives the arc-bottom hopper 31c to move horizontally.

[0037] The curved bottom design of hopper 31c increases the effective volume of the sterilization cart within a limited space. The porous structure of the curved bottom allows wastewater to drain promptly, ensuring effective sterilization of medical waste by steam. Hopper 31c can be raised and lowered by lifting structure 31a and moved horizontally by horizontal drive structure 31b. When medical waste to be sterilized needs to be sent into sterilization chamber 1a, the height of hopper 31c can be adjusted via lifting structure 31a to match the waste storage device. After loading the waste, hopper 31c is moved to the sterilization hatch of sterilization chamber 1a via horizontal drive structure 31b, and the height is adjusted before the waste is sent into the chamber. After sterilization, the position of hopper 31c is adjusted via lifting and horizontal structures to transfer the sterilized waste from the chamber to the feed end of crusher 200a. Through the coordinated lifting and horizontal movement, transfer unit 3a can flexibly adapt to the positional requirements of different operation stages, achieving seamless connection between the two core processing units, reducing manual intervention, and improving overall processing efficiency.

[0038] The steam supply unit 4a, as a key unit providing sterilization medium to the sterilization chamber 1a, must be structurally designed to ensure stable steam generation and precise delivery, while also adapting to the pressure and temperature requirements of the sterilization chamber 1a. The steam supply unit 4a includes: a water softener, whose inlet is connected to the water inlet pipe outside the chamber; a water tank 41a, whose inlet is connected to the outlet of the water softener; a steam generator 42a, whose inlet is connected to the water tank 41a, and whose first steam outlet is connected to the steam inlet of the sterilization chamber 1a via a steam inlet pipe; a steam jet pump 43a, whose steam inlet is connected to the second steam outlet of the steam generator, and whose suction port is connected to the vacuum port via a vacuum pipe; and a water pump 44a is installed between the water tank 41a and the steam generator 42a. From the steam generator 42a to the sterilization chamber 12a, a first pneumatic angle seat valve, a steam jet pump 43a and a pneumatic butterfly valve are sequentially installed on the vacuum pipeline. A second pneumatic angle seat valve 45a, a bellows 46a and a pneumatic regulating valve 47a are sequentially installed on the steam inlet pipeline. The first pneumatic angle seat valve and the pneumatic butterfly valve are not shown in the figure.

[0039] Water tank 41a is used to store water softened by a water softener to prevent impurities and minerals in ordinary water from forming scale in steam generator 41a, which would affect the heat transfer efficiency and service life of steam generator 41a. Steam generator 41a can heat the softened water transported by water tank 41a to vaporize and generate steam that meets sterilization requirements. Steam jet pump 43a on the vacuum pipeline can create a vacuum environment in sterilization chamber 1a. On the one hand, it can assist in the discharge of air in sterilization chamber 1a during sterilization to ensure stable pressure in sterilization chamber 1a. On the other hand, it can assist in the discharge of exhaust gas in sterilization chamber 1a after sterilization, improving exhaust efficiency.

[0040] A water pump 44a is installed between the water tank 41a and the steam generator 41a. Through the power of the water pump 44a, the soft water in the water tank 41a can be stably delivered to the steam generator 41a, ensuring a continuous water supply to the steam generator 41a. A first pneumatic angle seat valve acts as an on / off valve, quickly controlling the opening and closing of the vacuuming pipeline. A second pneumatic angle seat valve 45a acts as an on / off valve, quickly controlling the opening and closing of the steam inlet pipeline. When evacuating the chamber, the first pneumatic angle seat valve is opened and the second pneumatic angle seat valve is closed. When introducing steam into the chamber, the second pneumatic angle seat valve is opened. The second pneumatic angle seat valve closes the first pneumatic angle seat valve; the corrugated hose 46a has good flexibility and can play a role in pipeline compensation, adapting to the slight displacement between the steam generator 41a and the sterilization chamber 12a caused by installation errors or temperature changes, and can also absorb the vibration generated by steam entering the pipeline, avoiding damage to the pipeline due to rigid connection; the pneumatic regulating valve 47a is used to regulate the steam delivery flow rate, accurately controlling the steam input according to the temperature and pressure requirements in the sterilization chamber 1a, ensuring that the sterilization chamber 1a is always maintained in a high temperature and low pressure environment that meets the requirements. Through the synergistic effect of the above components, the steam supply unit 4a can stably and accurately provide steam to the sterilization chamber 1a1, ensuring the sterilization effect.

[0041] The purpose of the exhaust gas treatment unit 5a is to comprehensively treat the exhaust gas generated during the medical waste treatment process, ensuring that the final emissions meet environmental protection requirements. Its structure needs to realize the collection, multi-stage treatment, and compliant emission of exhaust gas. The exhaust gas treatment unit 5a includes a spray tower 51a, a gas-liquid separator 52a, a silencer 53a, a biological filter 54a, an activated carbon adsorber 55a, and a negative pressure fan 56a, and all components are connected in sequence to form a complete exhaust gas treatment pathway. The spray tower 51a is connected to the exhaust port of the steam jet pump 43a, which discharges the extracted steam and air mixture to the spray tower for treatment. The function of the spray tower is to pre-treat the waste gas by contacting the sprayed liquid with the waste gas, removing some soluble harmful components and dust particles. The gas-liquid separator 52a is connected to the spray tower 51a and is used to separate the liquid carried in the waste gas after spraying, preventing the liquid from entering subsequent structures and affecting the treatment effect, while also recovering some of the sprayed liquid. The silencer 53a is connected to the gas-liquid separator 52a. Since the waste gas may generate noise due to pressure changes during flow, the silencer 53a can reduce the noise during waste gas emission through sound absorption and sound insulation structures, reducing noise interference to the surrounding environment. The biological filter 54a is connected to the silencer 53a. It is filled with a PTFE filter element with a pore size of 0.22μm. Through the metabolic activity of microorganisms and the filtration effect of the microbial filter element, it biodegrades and filters out harmful organic components in the exhaust gas. The activated carbon adsorber 55a is connected to the biological filter 54a. Activated carbon has a porous structure and strong adsorption capacity, which can further adsorb harmful components remaining in the exhaust gas after treatment by the biological filter 54a, ensuring more thorough removal of harmful substances. The negative pressure fan 56a is connected to the activated carbon adsorber 55a. The negative pressure provided by the fan 56a ensures stable flow of exhaust gas throughout the entire treatment process, ensuring that the exhaust gas passes through each treatment unit sequentially and preventing accumulation in the pipeline. The outlet of the negative pressure fan 56a is connected to an exhaust pipe of a certain length.

[0042] To improve the treatment efficiency and economy of the spray tower 51a in the exhaust gas treatment unit 5a, the exhaust gas treatment unit 5a also includes a circulating pump 57a, a heat exchange coil 58a installed in the water tank 41a, and a spray water filter 59a. The three are connected in sequence to form a spray water circulation pipeline and are connected to the spray tower 51a. The diagram shows the portion of heat exchange coil 58a extending outside the water tank. The circulating pump 57a, serving as the power source for the spray water circulation, extracts the spray water from spray tower 51a, sends it into the circulation pipeline, and then returns it to spray tower 51a, achieving the recycling of spray water. Compared to single-use spray water, the circulation design significantly saves water resources and reduces treatment costs. The spray water filter 59a, a Y-type filter, is installed in the circulation pipeline. Its function is to filter impurities in the spray water. These impurities may originate from particulate matter in the exhaust gas or detached material from spray tower 51a. Without filtration, these impurities can easily clog the nozzles of spray tower 51a or the circulation pipeline, affecting the spraying effect. The filter ensures the unobstructed flow of the spray pipeline and the uniformity of the spray. The heat exchange coil 58a, also installed in the circulation pipeline, is used to regulate the temperature of the spray water. The temperature of the recycled spray water will rise rapidly. The high temperature spray water can exchange heat to the water tank 41a through the heat exchange coil 58a, so that the soft water in the water tank 41a is kept at a high temperature level, while the temperature of the spray circulating water is reduced, thereby reducing the energy consumption of the steam generator 41a.

[0043] Through the synergistic action of the circulating pump 57a, heat exchange coil 58a and spray water filter 59a, the spray system realizes the recycling of spray water, impurity filtration and heat exchange, which not only improves the stability and efficiency of spray treatment, but also reduces water consumption and equipment operating costs, and further optimizes the overall performance of the exhaust gas treatment unit 5a.

[0044] To prevent the escape of waste gas during medical waste treatment, the waste gas treatment unit 5a5 also includes a gas collection hood 510a. The gas collection hood 510a is positioned above the sterilization chamber door 13a and the crushing and compression unit 2a, and is connected to the activated carbon adsorber 55a, ensuring that the areas above the sterilization chamber door and the crushing and compression unit are always under negative pressure. In actual treatment, when the sterilization chamber door 13a is opened to receive or remove medical waste, a small amount of residual waste gas in the sterilization chamber 1a may easily escape from the open end into the surrounding environment. When the crushing and compression unit 2a crushes and compresses the sterilized waste, volatile substances that may adhere to the waste surface or dust and gases generated during the crushing process may also escape. The gas collection hood 510a positioned above the sterilization chamber door 13a can collect the waste gas that escapes when the sterilization chamber door 13a is opened and closed, and the gas collection hood 510a positioned above the crushing and compression unit 2a can collect the gases (including vapor) and dust that escape during the crushing and compression process.

[0045] The escaping exhaust gas collected by the gas collection hood 510a is sent to the activated carbon adsorber 55a through pipelines. It undergoes final adsorption treatment together with the exhaust gas that has been treated by spraying and biological filtration, ensuring that the escaping exhaust gas can also be effectively treated, preventing it from directly spreading to the operating area or the surrounding environment, reducing the impact on the health of operators, and further improving the exhaust gas collection rate and treatment integrity of the entire container, ensuring that there is no exhaust gas pollution.

[0046] To ensure the stable and reliable operation of the compressor 300a and the lifting structure 31a, the medical waste treatment cabin in this embodiment is also equipped with a hydraulic workstation 6a. The hydraulic workstation 6a provides hydraulic medium to the compressor 300a and the lifting structure 31a to drive them to complete the corresponding actions.

[0047] like Figure 5 As shown, the present invention also provides a method for treating medical waste, wherein the medical waste treatment container provided by the above technical solution includes: Step S1: The medical waste is transferred into the sterilization chamber 1a for sterilization via the transfer unit 3a. Step S2: The sterilized medical waste is transferred into the crushing and compression unit 2a under the transfer of the transfer unit 3a, crushed into particles and compressed into bales. Step S3: Push the compressed block inside the crushing and compression unit 2a to the outside.

[0048] Furthermore, Step S1 includes: The lifting structure 31a is activated, and the hopper 31c containing medical waste is raised to a specified height via the lifting structure 31a. The sterilization chamber door 13a of the sterilization chamber 1a is opened and the horizontal drive structure 31b is started. The hopper 31c is transferred to the designated position in the sterilization chamber 1a for sterilization through the horizontal drive structure 31b. After the lifting structure 31a and the horizontal drive structure 31b are reset, the sterilization chamber door 13a of the sterilization chamber 1a is closed.

[0049] Furthermore, Step S2 includes: The sterilization chamber door 13a of the sterilization chamber 1a is opened and the lifting structure 31a is activated, and the lifting structure 31a is raised to a specified height. The horizontal drive structure 31b is started, and the hopper 31c is transferred out of the chamber through the horizontal drive structure 31b and transferred to the crusher 200a. The hopper 31c is raised further by the lifting structure 31a until it reaches the feed inlet of the crusher 200a. The horizontal drive structure 31b continues to push the hopper 31c to move, aligning the discharge port of the hopper 31c with the feed port of the crusher 200a, so that the medical waste in the hopper 31c falls into the crusher 200a for crushing, and the crushed medical waste enters the crusher 200a for compression into bales. Control the compression pusher to push the compressed package to the outside; The control lifting structure 31a and the horizontal drive structure 31b are reset.

[0050] Specifically, the processing methods include: Feeding stage: The packaged medical waste is directly loaded into the hopper 31c. The weighing module of the weighing platform 500 monitors the loading amount in real time. When the set value is reached, a prompt is issued and loading is stopped. The hopper 31c is sent into the sterilization chamber 1a through the horizontal drive structure 31b. Sterilization stage: Vacuum the sterilization chamber 1a to -0.09MPa in a single operation, or pulsate it to -0.08MPa, then fill it with high-temperature steam to raise the temperature to 135-136℃ and maintain the pressure at 0.23-0.24MPa. Start timing when the temperature and pressure reach 134℃ and the pressure reaches 0.22MPa, and continue sterilization for 45 minutes. After sterilization, start the exhaust program. When the pressure inside the sterilization chamber drops to 0.05MPa, start the drainage stage to facilitate faster and better discharge of wastewater. After drainage, start the drying program and repeatedly vacuum to -0.05-0.07MPa to dry the waste and reduce its moisture content. After drying, introduce air to break the vacuum and equalize the pressure inside and outside the chamber, then open the sterilization chamber door.

[0051] Transfer stage: After sterilization, the horizontal drive structure 31b docks with the sterilization chamber 1a, and moves the sterilization hopper 31c out smoothly to the crusher 200a. The hopper is then lifted to the feed inlet of the crusher 200a by the lifting mechanism. Crushing and Compression Stage: The sterilized medical waste in hopper 31c is automatically pushed in batches to the feed inlet of crusher 200a by pushers, allowing the sterilized medical waste to fall into the crusher for crushing. The crushed material then falls into compressor 300a and is compressed four times at a 5:1 compression ratio, forming regular bales weighing approximately 23kg each. It should be noted that the pushers push the sterilized medical waste to the crusher feed inlet in batches to ensure that the amount of crushed material falling into the compression structure is appropriate, facilitating the achievement of a 5:1 compression ratio under the given pressure. Simultaneously, the compressed bales are not excessively heavy, making them easy for a single adult to handle. The compression amount of each batch of waste is determined by the pusher plate of the arc-bottom hopper. Discharge stage: After compression is completed, the discharge port of the compression structure opens automatically, and the compression push plate 302 pushes out the compressed bale, which is collected by the transfer vehicle; the wastewater generated during the process is discharged after being treated by an ultraviolet sterilizer, and the exhaust gas is discharged after being treated by multiple stages of spray tower 51a, gas-liquid separator 52a, sterilization filter and activated carbon adsorption box to meet the emission standards.

[0052] The crushing and compression unit 2a is the integrated crushing and compression device in Embodiment 2, the crushing structure 200 is the crusher 200a, the compression structure 300 is the compressor 300a, the transfer unit 3a is the transfer device in Embodiment 3, and the horizontal drive structure 31b includes the assembly structure 600 and the translation structure 700. Example 2

[0053] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the present invention provides an integrated crushing and compression device, including a crushing structure 200, a compression structure 300 and a frame 100. The crushing structure 200 is disposed on the frame 100 and has a discharge port at the bottom. The compression structure 300 is disposed below the crushing structure 200 and has a feed port at the top that communicates with the discharge port 205 of the crushing structure.

[0054] In the embodiments of the present invention, the above-described configuration integrates the crushing structure 200 and the compression structure 300, thereby improving the overall compactness of the equipment layout. Furthermore, it enables medical waste within the crushing structure 200 to naturally fall into the compression structure 300, thus improving the efficiency of medical waste treatment and reducing the labor intensity of operators.

[0055] The crushing structure 200 can be a double-toothed roller crushing structure 200, which can effectively crush medical waste after high-temperature sterilization, ensuring that large particles are processed into small particles of uniform size, facilitating the compression process. The compression structure 300 can be a hydraulically driven compression structure 300, whose inlet is directly connected to the outlet 205 of the crushing structure. It can receive the crushed small particles and compress them into compact block solids according to a preset volume ratio, while squeezing out residual medical wastewater, reducing the overall weight of the treated waste, and facilitating subsequent collection and transportation. The frame 100 can be a frame structure made of high-strength hollow square steel welded together and fixed to the ground with bolts. It can not only provide stable support for the crushing structure 200 and the compression structure 300, but also precisely limit the two components through preset installation positions, ensuring that the two maintain a stable relative position during operation and avoiding the impact of component displacement on the connection and transmission of materials.

[0056] The crushing structure 200 and the compression structure 300 are integrated together by the frame 100, eliminating the need for separate equipment and installation space for the two processes, effectively reducing the overall footprint of the equipment. At the same time, the crushing structure 200 and the compression structure 300 are directly connected. Specifically, the compression structure 300 is located below the crushing structure 200, and the discharge port 205 of the crushing structure is located above the feed port 306 of the compression structure. This allows the crushed material to fall naturally into the compression structure 300, eliminating the intermediate transfer link, reducing the labor intensity of operators, improving processing efficiency, and reducing the risk of material spillage during transfer, which meets the hygiene and efficiency requirements of medical waste treatment.

[0057] To ensure that the crushing structure 200 can stably and efficiently complete the material crushing operation, the crushing structure 200 specifically includes a crushing box 201, crushing rollers 202, and a crushing drive component 203. The crushing box 201 is made of stainless steel, and its inner wall is lined with a wear-resistant lining to prevent excessive wear on the box during the crushing process. Stainless steel is also easy to clean and meets the hygiene standards for medical waste disposal. The crushing rollers 202 are a pair of interlocking rollers with anti-slip teeth on their surfaces. When material enters the crushing box 201, the interlocking action between the two rollers squeezes and shears the material, ensuring that large particles are crushed uniformly and preventing material jamming or incomplete crushing. The crushing drive component 203 is connected to the crushing rollers 202, providing power for their rotation and ensuring that the crushing rollers 202 maintain a stable rotational speed, thereby guaranteeing the continuity and stability of the crushing operation.

[0058] The intermeshing pair of crushing rollers 202 can exert bidirectional force on the material, resulting in higher crushing efficiency and more uniform particle size after crushing compared to a single crushing roller 202. The wear-resistant lining of the crushing box 201 extends the service life of the equipment, while the stainless steel material reduces the difficulty of cleaning and the risk of pathogenic microorganism residue. The crushing drive component 203 provides continuous power to the crushing rollers 202102, avoiding interruption of crushing operations due to insufficient power and ensuring the stable progress of the entire crushing process.

[0059] To further optimize the feeding effect of the crushing structure 200, the crushing structure 200 also includes a feeding hopper 204. The bottom of the feeding hopper 204 is connected to the top of the crushing box 201, ensuring that the material in the hopper can smoothly enter the crushing box 201 for crushing. The feeding hopper 204 adopts an inverted conical opening design, and the size of the opening 101 at the top gradually increases in the direction away from the crushing box 201. This structure facilitates the batch pouring of medical waste into the feeding hopper 204 by operators or automated equipment, and also avoids spillage of materials during the pouring process. At the same time, the inner wall of the conical structure can guide the material to slide down naturally, reducing the accumulation of materials in the feeding hopper 204.

[0060] The gradually increasing design of the open section 101 expands the feeding range and reduces the difficulty of feeding operations, making it particularly suitable for the high-efficiency feeding requirements when processing medical waste in batches. The feeding hopper 204 is directly connected to the crushing box 201, allowing materials to enter the crushing box 201 without passing through other transfer structures, reducing the residence time of materials in the feeding process and further improving the efficiency of the entire crushing process. At the same time, the inverted cone structure effectively avoids the accumulation of materials in the feeding hopper 204, reducing the feeding blockage problem caused by material accumulation and ensuring smooth feeding.

[0061] To ensure stable and efficient operation of the crushing roller 202, the crushing drive unit 203 uses two geared motors with their output shafts arranged vertically and horizontally. The two geared motors are installed on opposite sides of the crushing box 201, and the output shaft of each geared motor is connected to one crushing roller 202 via a coupling. This installation method allows the power of the geared motor to be directly transmitted to the crushing roller 202, reducing power loss. Simultaneously, the vertical and horizontal arrangement of the output shafts allows the geared motors to be installed on the side of the crushing box 201 without occupying the feeding space above the crushing box 201, thus avoiding interference with the installation and feeding operation of the hopper.

[0062] Two geared motors drive two crushing rollers 202 respectively, enabling independent control of the speed of each crushing roller 202. This allows for adjustment of the speed according to the hardness and particle size of the material, ensuring the meshing effect between the two rollers and thus guaranteeing the crushing quality. The geared motors reduce the output speed of the motors and increase the torque, providing sufficient crushing force to the crushing rollers 202 and preventing jamming of the crushing rollers 202 due to insufficient torque. In addition, the motors are installed on both sides of the crushing box 201, which is not only reasonable in layout but also facilitates the maintenance and repair of the motors in the future.

[0063] The bottom of the crushing structure 200 is provided with an opening, and a discharge hopper extending downward is provided at the opening. The inner perimeter of the discharge hopper forms the discharge port 205 of the crushing structure. The discharge port 205 of the crushing structure gradually expands from top to bottom, which is conducive to the dispersion of medical waste entering the compression structure 300.

[0064] Furthermore, the crushing structure 200 is supported on the frame 100; the compression structure 300 is located below the frame 100 where the crushing structure 200 is located. Specifically, the frame 100 is a groove-shaped structure with the groove opening facing downwards; the crushing structure 200 is supported on the bottom wall of the groove of the frame 100; the compression structure 300 is located in the groove of the frame 100, so that the frame 100 supports the crushing structure 200 while limiting the compression structure 300.

[0065] More specifically, the two side walls of the frame 100 are respectively provided with openings 101; the compression structure 300 is placed in the slot of the frame 100 through the opening 101 on one side of the frame 100, and its discharge port faces the opening 101 on the other side of the frame 100. Medical waste from the discharge port of the compression structure 300 is taken out through the opening 101 of the frame 100.

[0066] Furthermore, a through opening 102 is provided on the bottom wall of the slot of the frame 100; The crushing structure 200 is supported on the frame 100 on the outer periphery of the through opening 102; The discharge port 205 of the crushing structure extends downward, passes through the through port 102, and extends to the inlet port 306 of the compression structure, so that the discharge port 205 of the crushing structure can be close to the inlet port 306 of the compression structure, preventing medical waste from leaking during the transfer process.

[0067] Furthermore, the lower end of the discharge port 205 of the crushing structure is bent outward to form a support part 206; The feed inlet 306 of the compression structure is provided with several spaced ribs 307 on its outer periphery; The support part 206 is supported and abuts against several ribs 307, and cooperates with the discharge port 205 of the crushing structure to cover the feed port 306 of the compression structure.

[0068] The ribs 307 of the compression structure 300 can increase the structural strength of the compression structure 300 and can abut against the support part 206 of the crushing structure 200 to stably support the crushing structure 200, thereby achieving stability between the compression structure 300 and the crushing structure 200. In addition, the crushing box 201 of the crushing structure 200 supports and is fixed to the frame 100, thereby achieving stability among the compression structure 300, the crushing structure 200 and the frame 100.

[0069] The support 206 and the discharge port 205 of the crushing structure cover the inlet 306 of the compression structure, which can further prevent medical waste from leaking during the transfer process.

[0070] Furthermore, at least one of the two non-open slot sidewalls of the frame 100 protrudes outward from the slot to form an auxiliary frame 103 disposed below the frame 100; The crushing drive component 203 of the crushing structure 200 is supported on the auxiliary frame 103.

[0071] Preferably, the two non-open trough sidewalls of the frame 100 are respectively provided with auxiliary frames 103, and the two crushing drive components 203 of the crushing structure 200 are respectively supported on the corresponding auxiliary frames 103. The two auxiliary frames 103 are arranged with the frame 100 as the center. The two auxiliary frames 103 are set lower than the frame 100, and their bottoms are flush with the frame 100. The bottom of the frame 100 and the bottom of the auxiliary frames 103 are in contact with the ground or other supporting platforms.

[0072] The two openings 101 of the frame 100 are located on the front and rear sides of the frame 100. The compression box 301 of the compression structure 300 is placed in the groove of the frame 100 along the front and rear direction. The ribs 307 on the compression box 301 extend along the front and rear direction. Several ribs 307 are arranged at intervals along the left and right direction. Two auxiliary frames 103 are located on the left and right sides of the frame 100.

[0073] The compression structure 300 includes a compression box 301, a compression push plate 302, and a compression drive component 303. The compression box 301 has a discharge port and a gate 304 for opening and closing the discharge port on one side. A compression chamber is formed inside the compression box 301 that extends and retracts relative to the gate 304. The inlet 306 of the compression structure is located on the path of the compression chamber's contraction to ensure that there is medical waste in the compression chamber during compression.

[0074] Specifically, the compression box 301 is equipped with a compression push plate 302; The outer periphery of the compression pusher plate 302 is in contact with the inner wall of the compression box 301 and slides toward or away from the gate 304; When the gate 304 is closed, the compression push plate 302 cooperates with the inner wall of the gate 304 and the compression box 301 to form a compression cavity, and when the gate 304 is open, it acts as a push plate.

[0075] The bottom of the compression chamber 301 is directly connected to the bottom of the crushing chamber 201. The crushed material can fall naturally into the compression chamber 301 through the connection, eliminating the need for additional transfer and achieving a seamless connection between the crushing and compression processes, thus avoiding material loss and contamination during transfer. The compression pusher plate 302 is made of high-strength metal, and its outer periphery fits tightly against the inner wall of the compression chamber 301. It can also slide along the inner wall of the compression chamber 301, ensuring that no material leaks out from the gaps during the movement of the compression pusher plate 302, ensuring that the material can be fully compressed and improving the compression and volume reduction effect. The compression drive component 303 is connected to the compression pusher plate 302 and can drive the compression pusher plate. 302 slides back and forth within the compression chamber 301, providing sufficient thrust for material compression. The gate 304 is located at one end of the compression chamber 301. When closed, the gate 304 and the compression pusher plate 302 form a variable-volume compression chamber, where the material is compressed. After compression, the gate 304 opens to facilitate the discharge of the compressed blocky solid to the outside of the compression chamber 301. The compression pusher plate 302 pushes the blocky solid to the outside of the compression chamber 301. The compression drive component 303 provides stable thrust to ensure the reliability of the compression process. The opening and closing design of the gate 304 enables the orderly switching between compression and discharge, ensuring that the entire compression process is continuous and efficient. The compression drive 303 can be a first hydraulic cylinder 3031. The compression push plate 302 divides the interior of the compression chamber 301 into a first space and a second space along the length of the compression chamber 301. The first space forms a compression cavity, and the second space is used to install the compression drive 303. The drive shaft of the first hydraulic cylinder 3031 moves along the length of the compression chamber 301. Figure 4 As shown, the length direction of the compression box 301 is the front-to-back direction.

[0076] The discharge port of the compression chamber 301 serves as the discharge port of the compression structure 300. The discharge port of the compression chamber 301 is equipped with a discharge section 308 of a certain extension length. The discharge section 308 is connected to or disconnected from the interior of the compression chamber 301 via a gate. The compression pusher plate 302 pushes the blocky solids to the outside of the compression chamber 301, specifically to the discharge section 308, to prevent the blocky solids from falling and to facilitate their removal. The discharge section 308 and the gate 304 extend into the slot of the frame 100 through an opening 101 on one side of the frame.

[0077] The gate 304 includes a gate panel and a gantry frame 3041 with an internal hollow cavity forming a receiving cavity. The gantry frame 3041 is fixed at the discharge port of the compression box 301; the gate panel retracts vertically relative to the receiving cavity; when the gate panel extends out of the receiving cavity, the gate 304 is open, and when the gate panel retracts into the receiving cavity, the gate 304 is closed. Specifically, the top of the receiving cavity is provided with an opening; the top of the door panel is provided with a movable part 3042; The door panel retracts into or extends out of the receiving cavity through the opening; A door panel drive member 305 is connected to the moving part 3042 to drive the moving part 3042 to move in the vertical direction; the door panel drive member 305 includes two second hydraulic cylinders 3051, which are located on both sides of the gate 304. The outwardly protruding parts on both sides of the moving part 3042 are connected to the drive ends of the second hydraulic cylinders 3051. Specifically, the second hydraulic cylinders 3051 are supported on the ground or other platform, and the cylinder rods of the second hydraulic cylinders 3051 extend and retract in the vertical direction. The drive ends of the cylinder rods are used to support the moving part 3042.

[0078] The sliding gate panel is mounted on the compression chamber 301, ensuring the flexibility of the gate 304's opening and closing, and enabling rapid sealing of the compression chamber and opening of the discharge port. The gantry frame 3041 provides stable support for the gate panel, ensuring uniform force distribution during sliding and preventing deformation or damage due to uneven force. The wear-resistant material of the gate panel extends the service life of the gate 304 and can withstand the friction and impact when compressed solid blocks are discharged. In addition, the vertical sliding method ensures that the gate 304 does not occupy the space on both sides of the compression chamber 301 after opening, facilitating the installation of a collection device below the compression chamber 301 and improving the overall rationality of the equipment layout. Example 3

[0079] like Figure 10 , Figure 11 , Figure 12 as well as Figure 13 As shown, the present invention provides a hopper transfer device, including a lifting support 400, a weighing platform 500, a docking structure 800, an assembly structure 600, a translation structure 700, and a control structure 900.

[0080] The weighing platform 500 has two ends along its length, one for the hopper to enter and the other for the hopper to exit. The entry end of the weighing platform 500 faces the discharge port of the sterilization equipment, and the exit end faces the inlet of the crushing equipment. The sterilization equipment moves the hopper carrying the sterilized medical waste to the discharge port. Because the discharge port of the sterilization equipment and the inlet of the crushing equipment are at different heights, a lifting bracket 400 is needed to adjust the height of the weighing platform 500 to accommodate the different equipment. This setup allows for automatic transfer of medical waste to the crushing equipment without operator intervention, reducing the number of times operators come into contact with the medical waste during transport and lowering the risk of infection and burns.

[0081] The docking structure 800 is located on the side of the weighing platform 500 facing the sterilization equipment and is used for horizontal docking with the discharge port of the sterilization equipment. The assembly structure 600 is used to move the hopper from the discharge port of the sterilization equipment onto the weighing platform 500. The translation structure 700 is installed on the weighing platform 500 and connects the assembly structure 600 and the docking structure 800. The translation structure 700 is used to move the assembly structure 600 and the docking structure 800 together closer to or further away from the sterilization equipment. The control structure 900 is located on the side of the weighing platform 500 facing the crushing equipment. The control structure 900 is used to control the automatic dumping of medical waste in the hopper to the feed inlet of the crusher.

[0082] Furthermore, the weighing platform 500 includes two first crossbeams 510 extending along the length of the weighing platform 500; The translation structure 700 includes a translation slide 710, which is suspended and slidably mounted on two first crossbeams 510; The assembly structure 600 includes an assembly bracket 610, which is located outside the two first crossbeams 510 and is slidably mounted on the first crossbeams 510. The assembly bracket 610 is fixedly connected to the translation slide 710.

[0083] There are two assembly brackets 610, which slide on the corresponding first crossbeams 510 respectively. The area between the two first crossbeams 510 is the inner area, and the two assembly brackets 610 are outside the two first crossbeams 510. Specifically, an auxiliary crossbeam parallel to the first crossbeam 510 is supported above the first crossbeam 510, and the assembly brackets 610 slide on the auxiliary crossbeam. The translational slide 710 is connected to the first crossbeam 510 via a first slider and slides along the length of the weighing platform 500 on the first crossbeam 510. The first slider is groove-shaped and is fastened to the first crossbeam 510 with the groove opening facing upwards. The translational slide 710 is fixedly connected to the bottom wall of the groove of the first slider. Figure 10 As shown, the length direction of the weighing platform 500 is the left-right direction; The assembly bracket 610 is connected to the auxiliary crossbeam via the second slider and slides on the auxiliary crossbeam along the length of the weighing platform 500. The second slider is groove-shaped and is fastened to the auxiliary crossbeam with the groove facing downward. The arrangement of the first slider and the second slider improves the stability and smoothness of the sliding of the translation slide 710 and the assembly bracket 610.

[0084] Furthermore, the assembly bracket 610 has a sliding part 620 and a support part 630 that are distributed vertically on one side facing the first crossbeam 510. The sliding part 620 is slidably disposed on the first crossbeam 510; The side of the translation slide 710 near the entry end of the weighing platform 500 is fixed to the support part 630.

[0085] The sliding part 620 is provided on the bottom wall of the groove that supports and is fixed to the second slider; the translation slide 710 is clamped between the first slider and the support part 630, which increases the stability of the movement of the translation slide 710 and the assembly bracket 610.

[0086] Furthermore, a second crossbeam 520 parallel to the first crossbeam 510 is provided on one side; The side of the translation slide 710 away from the weighing platform 500 is slidably mounted on the second crossbeam 520 via the sliding member 720; A first driving component 750 is connected to the sliding component 720. The first driving component 750 is a servo electric cylinder 7501. The servo electric cylinder 7501 is fixed on the weighing platform 500.

[0087] The second crossbeam 520 is positioned higher than the first crossbeam 510, and the two first crossbeams 510 are located between the two second crossbeams 520; The sliding component 720 enables a sliding connection between the translational carriage 710 and the second crossbeam 520; Specifically, the sliding component 720 has a plate-like structure and is groove-shaped; The sliding member 720 is fastened to the second crossbeam 520 with the slot facing downwards; The end of one sidewall of the sliding member 720 protrudes outward from the groove to form a first fixing part 730 that fits against and is fixedly connected to the bottom of the translational slide 710; The other sidewall of the sliding member 720 protrudes outward to form a second fixing part 740 that is fixedly connected to the first driving member 750.

[0088] The slider 720 slides on the second crossbeam 520 via the third slider, which is groove-shaped and engages with the second crossbeam 520 with the groove facing downwards; specifically, the slider 720 engages with the third slider with the groove facing downwards. The servo electric cylinder 7501 extends along the length of the weighing platform 500. The servo electric cylinder 7501 is located outside the two second crossbeams 520, and the output end of the servo electric cylinder 7501 is fixedly connected to the second fixing part 740.

[0089] The assembly structure 600 also includes an assembly gear set 640 and a second drive component 650;

[0090] Two sets of assembly gear groups 640 are provided, each corresponding to one of the two group-shaped supports. The assembly gear group 640 includes several vertically meshing assembly gears. The assembly gears rotate along the length of the weighing platform 500. The assembly gear located at the bottom is connected to the second drive member 650, which is used to control the rotation of the assembly gear. The assembly gear located at the top meshes with the rack 6 provided at the bottom of the hopper.

[0091] Additionally, a second drive unit 650 is mounted at the bottom of the translation slide 710. The second drive unit 650 includes a servo motor 6501, a reducer, and a universal joint coupling connected in sequence. The output end of the universal joint coupling is connected to the lowest assembled gear. The servo motor 6501 drives the assembled gear to rotate, thereby moving the hopper onto the weighing platform 500 through meshing with the rack 8 of the hopper. Multiple sets of assembled gears 640 can be connected simultaneously via the universal joint coupling.

[0092] The docking structure 800 includes a docking support 810, a docking rod 830, and a docking flange 820.

[0093] The docking support 810 is installed on the side of the translation slide 710 facing the entry end of the weighing platform 500, that is, the side of the translation slide 710 facing the discharge port of the sterilization equipment. The docking rod 830 is installed on the docking support 810 and is used to insert into the docking hole on the sterilization equipment. The docking flange 820 is installed on the docking support 810 and is used to connect with the electromagnetic clutch 9203 on the sterilization equipment.

[0094] When the servo electric cylinder 7501 drives the translation slide 710 to approach the inlet of the weighing platform 500, that is, when it approaches the outlet of the sterilization equipment, the docking rod 830 first gradually inserts into the docking hole of the sterilization equipment, and finally the docking flange 820 connects with the electromagnetic clutch 9203 on the sterilization equipment. The electromagnetic clutch 9203 can keep the connection between the translation slide 710 and the sterilization equipment stable and uninterrupted, ensuring a stable connection environment for the meshing transmission of the gears and the rack of the hopper in the subsequent assembly.

[0095] After the hopper moves to the weighing platform 500, the docking flange 820 and the electromagnetic clutch 9203 are disconnected. The drive assembly gear rotates until the hopper reaches a position approximately 100 mm away from the control structure 900. After the assembly gear stops rotating, the lifting bracket 400 is first raised to the discharge height, and then the servo electric cylinder 7501 retracts, driving the translation slide 710 to reset, thereby driving the hopper to move to the control structure 900. The flange on the hopper docks with the electromagnetic clutch 9203, and at the same time, the control slide rod 553 slides into the insertion hole 9103. The hopper door 2 is automatically opened under the drive of the connecting rod. After the door 2 is opened, the push plate 3 inside the hopper dumps the medical waste.

[0096] To ensure smoother movement of the hopper on the weighing platform 500, a receiving slide rod 530 is installed on the top of the weighing platform 500, which slides horizontally with the bottom of the hopper. A limiting guide rail 540, arranged along the length of the weighing platform 500, is located on the top of the receiving slide rod 530. A guide wheel assembly 9 is slidably connected within the limiting guide rail 540. Multiple sets of guide wheels are installed on the side wall of the hopper basket 1 and spaced apart along the length of the hopper. The end of the limiting guide rail 540 facing the sterilization equipment is closed, thereby limiting the sliding distance of the hopper.

[0097] The guide wheel assembly 9 includes rollers 91 and guide arc blocks 92. The rollers 91 are vertically arranged and rotatably mounted on the hopper basket 1. The guide arc blocks 92 are mounted on the hopper basket 1, and the end face facing away from the hopper basket 1 is an outwardly convex arc surface. Multiple sets of roller assemblies are arranged at intervals along their own trajectory within the limiting guide rail 540. Each roller assembly includes two rollers arranged in parallel and rotating. The arc surface of the guide arc block 92 slides against the peripheral wall of the roller.

[0098] As the hopper enters the weighing platform 500, its bottom end rolls on the receiving slide bar 530. The guide block 92 and roller 91 both enter the limiting guide rail 540. The roller 91 reduces the friction between the hopper and the receiving slide bar 530. The guide block 92 contacts the peripheral wall of the roller as it moves, causing the roller to roll. This further reduces friction with the hopper while completing the limiting guidance, thus lowering the load on the drive assembly gear and rack. The control structure 900 includes a first control element 910 for controlling the opening of the hopper's door panel and a second control element 920 for controlling the movement of the push plate inside the hopper towards the door panel. The first control element 910 is located on the side of the second control element 920 closest to the assembly structure 600.

[0099] First, the door panel is opened by the first control component 910, and then the push plate 3 inside the hopper is moved along the direction close to the door panel 2 by the second control component 920, thereby pushing the medical waste away from the hopper. The door panel is directly facing the feed inlet of the crushing equipment, thus completing the dumping of the medical waste.

[0100] The first control component 910 includes a first bracket 9101 and a first insertion rod 9102. The first bracket 9101 is mounted on the weighing platform 500 and the first insertion rod 9102 is mounted on the first bracket 9101. The first insertion rod 9102 has an insertion hole 9103 at one end facing the entry end of the weighing platform 500 for horizontally inserting a control slide rod that passes through the side wall of the feeding hopper. The first bracket 9101 is located outside the weighing platform 500 and is positioned higher than the limiting guide rail 540. The movement of the inner push plate of the hopper is controlled by a control slide rod 553 extending from the side wall of the hopper. When the control slide rod 553 slides away from the door panel 2, the door panel opens. As the hopper approaches the first control member 910, the control slide rod on the hopper slides into the insertion hole 9103 and abuts against the wall of the insertion hole 9103. As the hopper continues to move, the control slide rod slides away from the door panel relative to the hopper, and the door panel opens until the hopper moves to abut against the closed end of the limit guide rail 540.

[0101] Additionally, the second control component 920 includes a second bracket 9201, a control motor 9202, and an electromagnetic clutch 9203. The second bracket 9201 is mounted on the weighing platform 500, the control motor 9202 is mounted on the second bracket 9201 and its output shaft is connected to the electromagnetic clutch 9203. The electromagnetic clutch 9203 is used to dock with the flange on the linear guide rail of the hopper. The second bracket 9201 is located outside the weighing platform 500 and is positioned higher than the limit slide rail. The electromagnetic clutch contacts the flange, which is connected to the synchronous pulley via a drive shaft. The synchronous pulley is mounted on the four corner columns of the hopper. Under the operation of the motor 9202, the synchronous belt drives the push plate 3 to move closer to the door plate 2, so as to push the medical waste into the feed inlet of the crushing equipment.

[0102] Before medical waste is pushed out of the hopper and before the hopper enters the weighing platform, the lifting support 400 needs to adjust the height of the weighing platform 500. To know the weight of the medical waste in the hopper, a weighing sensor can be installed between the weighing platform 500 and the lifting support 400 to record the weight of the medical waste each time it is crushed.

[0103] The implementation principle of the hopper transfer device in this embodiment of the invention is as follows: When the sterilization equipment transports the hopper carrying medical waste to the discharge port, the lifting bracket 400 controls the docking structure 800 to be horizontally aligned with the docking interface facing the sterilization equipment. The translation structure 700 drives the docking structure 800 and the assembly structure 600 to approach the sterilization equipment together until the docking structure 800 contacts and connects to the sterilization equipment. Subsequently, the assembly structure 600 drives the hopper located at the discharge port to move horizontally onto the weighing platform 500. Then, the docking structure 800 disconnects from the sterilization equipment, and the translation structure 700... Structure 700 controls docking structure 800 and assembly structure 600 to move away from the sterilization equipment. Then, assembly structure 600 continues to move the hopper toward control structure 900 until it contacts control structure 900. Control structure 900 controls the medical waste in the hopper to be automatically poured into the feed inlet of the crushing box, specifically into feed hopper 204. The entire process does not require operators to approach the hopper and weighing platform, thereby reducing the number of times operators come into contact with medical waste during medical waste transfer and reducing the risk of infection and high-temperature burns to operators during the transfer process. Example 4

[0104] like Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, the present invention provides a hopper structure, including an upward-opening hopper basket 1, a door panel 2, and a pusher plate 3.

[0105] The hopper 1 includes an outer support frame 11 and an inner liner 12. Multiple drainage holes 4, penetrating the inside and outside of the hopper 1, are spaced apart on the bottom and side walls of the inner liner 12. A discharge port 13 is provided on one side of the hopper 1 along its length. A hinge connects the top of the door panel 2 and the support frame 11 located at the top of the discharge port 13, allowing the door panel 2 to rotate upwards or downwards to cover the discharge port 13. An opening and closing assembly 5 is provided between the hopper 1 and the door panel 2 to control the upward or downward rotation of the door panel 2. A pusher plate 3 is located inside the cavity of the inner liner 12, with its periphery adapted to fit against the inner wall of the inner liner 12. A pushing assembly 6 is provided between the hopper 1 and the pusher plate 3 to control the sliding of the pusher plate 3 along the length of the hopper 1.

[0106] When medical waste is placed in the hopper 1, the door panel 2 is closed, and the push plate 3 abuts against the side wall of the inner liner 12 opposite the door panel 2. The medical waste is located between the door panel 2 and the push plate 3. The drainage hole 4 not only allows the water accumulated in the medical waste to flow to the outside of the hopper, but also accelerates the cooling of the medical waste. The opening and closing assembly 5 controls the door panel 2 to flip upward and open the discharge port 13. The pushing assembly 6 controls the push plate 3 to move closer to the door panel 2, thereby pushing the medical waste away from the discharge port 13 from the hopper 1.

[0107] In addition, since medical waste tends to stick to the inner liner 12 under high temperatures, a high-temperature resistant anti-stick layer 7 is provided on the inner liner 12, push plate 3, and door panel 2 to improve this situation. The high-temperature resistant anti-stick layer 7 is preferably made of polytetrafluoroethylene, which is resistant to high temperatures and has a low coefficient of friction. The high-temperature resistant anti-stick layer 7 prevents medical waste from sticking to the inner liner 12, and the drain hole 4 penetrates through the high-temperature resistant anti-stick layer 7, so the drainage of accumulated water is not affected.

[0108] The combination of drainage hole 4 and high-temperature resistant non-stick layer 7 reduces the number of times operators come into contact with medical waste when moving and dumping it, thereby reducing the risk of infection and high-temperature burns to operators during the transportation of medical waste.

[0109] To further guide the condensate accumulated in the inner liner 12 out of the liner 12, the bottom of the inner liner 12 is a downwardly curved drainage arc surface 14, and a row of spaced drainage holes is provided at the lowest point of the bottom of the inner liner 12 along the length of the basket 1. The bottoms of the door panel 2 and the push plate 3 are adapted to the bottom of the inner liner 12 to prevent medical waste from leaking from the door panel 2 or from being missed when the push plate 3 pushes the medical waste.

[0110] The feeding assembly 6 includes a linear guide rail 61, a connector 62, and a guide member 63.

[0111] In this embodiment, linear guide rails 61 are installed on the support frame 11 and multiple sets are arranged on both sides of the push plate 3 along the width direction of the bucket 1.

In this embodiment, four linear guide rails 61 are provided, and the four linear guide rails 61 are arranged in pairs on both sides of the push plate 3 along the width direction of the bucket 1. The two linear guide rails 61 in the same group are arranged vertically, and the lower linear guide rail 61 is connected to the power source. Connecting the push plate 3 to the four linear guide rails 61 improves the stability of the push plate 3 during its movement. Figure 14 As shown, the length direction of the basket 1 of the present invention is the left-right direction, and the width direction of the basket 1 of the present invention is the front-back direction; Specifically, the linear guide rail 61 extends along the length of the bucket basket 1 and extends to the discharge port 13 to connect with the power source; The linear guide 61 is a synchronous belt, which moves back and forth along the length of the bucket basket 1 under the drive of the power source; The power source can be a device such as an electric motor that can drive the linear guide rail. An electromagnetic clutch is used to connect the power source and the linear guide rail 61. In this embodiment, the flange 64 of the electromagnetic clutch is connected to the linear guide rail 61 to facilitate quick connection of the power source.

[0112] The connector 62 is connected to the push plate 3 and the linear guide rail 61 respectively, causing the push plate 3 to move with the linear guide rail 61; the linear guide rail 61 moves, causing the connector 62 to move, thereby causing the push plate 3 to slide along the length of the basket 1. In addition, the connector 62 includes a slider 621, which is fixedly connected to the push plate 3 on the side facing the inside of the basket 1; The pressure plate 622 is fixed to the upper side of the slider 621 and cooperates with the slider 622 to clamp the linear guide 61. Specifically, the pressure plate 622 is used to fix the timing belt on the slider 622. The slider 621 and the pressure plate 622 are square block structures. The pressure plate 622 is fixed to the upper side of the slider 621 by screws. The slider 621, the pressure plate 622 and the linear guide 61 are fixed together, so that the slider 621 and the pressure plate 622 move linearly with the linear guide 61. The bottom surface of the pressure plate 622 is provided with a toothed structure that contacts the linear guide rail 61, increasing the friction between the pressure plate 622 and the linear guide rail 61 and improving the stability of the slider 621 and the pressure plate 622 as they move with the linear guide rail 61. The slider 621 has a locking part 623 protruding on the side facing the inside of the bucket basket 1; under the operation of the motor, the electromagnetic clutch drives the synchronous belt pulley to rotate, and the synchronous belt drives the slider 621, the locking part 623 and the push plate 3 to slide linearly.

[0113] Both the high-temperature resistant non-stick layer 7 and the inner liner 12 are provided with connecting grooves 15 arranged along the length of the basket 1. The snap-fit ​​part 623 passes through the connecting groove 15 into the basket 1 and connects with the push plate 3, and slides on the connecting groove 15.

[0114] Two fixing parts 32 are provided on the side of the flange facing the inside of the basket 1, which are distributed vertically. The two fixing parts 32 are located at the upper and lower parts of the notch 311, respectively. After the snap-fit ​​part 623 passes through the connecting groove 15, it slides into the notch 311. After being snapped into the notch 311, it is fixedly connected to the two fixing parts 32. The snap-fit ​​part 32 snapping into the notch 311 has a pre-positioning function for the fixed connection between the snap-fit ​​part 32 and the two fixing parts 32.

Specifically, the guide slide rod 631 is fixed to the top of the guide slide 632, and the two ends of the guide slide rod 631 are in contact with the two vertical beams at both ends of the crossbeam.

[0117] An opening and closing assembly 5 is provided between the support frame 11 and the door panel 2. Two sets of the opening and closing assembly 5 are located on both sides of the door panel 2 along the width direction of the basket 1. The opening and closing assembly 5 includes a hinged support 51 and a connecting rod assembly that causes the door panel 2 to flip up and down. The connecting rod assembly includes a first connecting rod 52, a second connecting rod 53, and a third connecting rod 54.

[0118] The hinged support 51 is installed on the support frame 11. Specifically, the hinged support 51 is installed on the crossbeam of the support frame 11. The linkage assembly is supported on the support frame 11 by the hinge support 51 and passes through the support frame 11 from top to bottom. Its upper end is hinged to the inner side of the door panel 2, and its lower end is hinged to the support frame 11 and slidably connected.

[0119] The center of the first link 52 is rotatably mounted on the hinge support 51 along the rotation direction of the door panel 2. One end of the second link 53 is rotatably hinged to one end of the first link 52 and the other end is rotatably hinged to the door panel 2. One end of the third link 54 is rotatably hinged to the other end of the first link 52. The other end of the third link 54 is connected to a control element 55 for controlling the rotation angle of the third link 54.

[0120] To improve the smoothness and stability of the opening and closing of the door panel 2, the first connecting rod 52 is a curved rod with an obtuse angle triangle shape, thicker in the middle and thinner at both ends, and the second connecting rod 53 is an arc-shaped rod that bends towards the door panel 2.

[0122] The lower end of the linkage assembly is hinged to and slidably connected to the support frame 11 via the control element 55.

[0123] The control component 55 includes a control slide 551, a control slider 552, and a control rod 553.
