Description

Technical Field

[0001] This invention relates to the field of medical waste treatment equipment technology, specifically a modular medical waste harmless treatment device. Background Technology

[0002] Medical waste possesses hazardous characteristics such as infectiousness and toxicity, and its generation is increasing year by year with the development of the medical industry. Improper handling can easily lead to public health safety and environmental pollution problems. National environmental protection regulations clearly require the implementation of full-process control of "volume reduction, sterilization, and compliant disposal." Existing treatment technologies are difficult to adapt to the needs of medical institutions of different sizes. Among the current mainstream technologies, incineration is energy-intensive and easily produces toxic gases, making it unsuitable for small and medium-sized institutions; landfilling requires large land areas and easily pollutes groundwater, and is gradually being restricted.

[0003] While high-temperature sterilization and biodegradation methods are more environmentally friendly, existing devices have significant drawbacks: First, they lack modularity, often featuring integrated designs with fixed processing units that are difficult to expand or maintain, and single-compartment degradation is prone to operational interruptions. Second, they lack intelligent control, with scattered sensor layouts and incomplete monitoring of key parameters, leading to incomplete sterilization and material blockage. Third, the lack of standardized interface design results in poor sealing, leakage risks, and inconvenient disassembly and maintenance. In summary, addressing the core pain points of existing devices—weak modularity, poor continuous operation, and low intelligence—there is an urgent need to develop a modular, closed-loop, end-to-end medical waste harmless treatment device to overcome industry technical bottlenecks and meet the requirements for safe and environmentally friendly treatment.

[0023] like Figures 1 to 6As shown, the modular medical waste harmless treatment device of this embodiment includes a feeding chamber 1, a pulverizing chamber 2 installed at the lower end of the feeding chamber 1, a sterilization chamber 5 installed at the lower end of the pulverizing chamber 2, a conveying pipe 7 installed at the lower end of the sterilization chamber 5, an auger conveyor installed inside the conveying pipe 7, a base 8 installed on the outer side of the conveying pipe 7, a rotating disk 9 installed at the upper end of the base 8, an installation disk 10 installed at the upper end of the rotating disk 9, a central column 12 installed at the center of the upper end of the installation disk 10, and equidistant arrays at the upper edge of the installation disk 10. Multiple side troughs 11 are provided, with degradation chambers 16 slidably installed inside each side trough 11. Multiple electric push rods 15 are equidistantly arrayed on the side wall of the central column 12, with the other end of each electric push rod 15 connected to a degradation chamber 16. Each degradation chamber 16 is connected to one end of a conveying pipe 7. The main structure consists of a feeding chamber 1, a crushing chamber 2, a sterilization chamber 5, a conveying pipe 7, and modular degradation units. Each module is connected via standardized interfaces to achieve the complete harmless treatment of medical waste. When medical waste is fed into the feeding chamber 1, it first enters… The lower crushing chamber 2 completes the volume reduction process; the crushed material falls into the sterilization chamber 5 for high-temperature sterilization; the sterilized material enters the conveying pipe 7 from the lower end of the sterilization chamber 5 and is pushed by the internal auger conveyor; a rotating disk 9 is provided on the upper end of the base 8 on the outside of the conveying pipe 7, and multiple side grooves 11 are opened on the edge of the mounting plate 10 on the top of the rotating disk 9. A degradation chamber 16 is slidably installed in each side groove 11. The electric push rod 15 on the side wall of the central column 12 can push the degradation chamber 16 to slide along the side groove 11, and the auger conveyor pushes the material to the end of the conveying pipe 7. When the electric push rod 15 drives the corresponding degradation chamber 16 to move to the discharge end of the conveying pipe 7, the two are connected and the material enters the degradation chamber 16; when the degradation chamber 16 is full of material, the electric push rod 15 pulls it to reset, and the rotating disk 9 drives the installation disk 10 to rotate, switching the empty degradation chamber 16 to the discharge end position of the conveying pipe 7. Through the rotation operation of the modular degradation chambers 16, it can adapt to the waste treatment volume of medical institutions of different sizes, realize continuous and uninterrupted harmless treatment, and each module can be disassembled and assembled independently, which is convenient for later maintenance and expansion.

[0024] Specifically, a track drive assembly 3 is installed at the outer end of the feeding chamber 1. Two rotating rollers 17 are symmetrically installed inside the feeding chamber 1. Both rotating rollers 17 are connected to the track drive assembly 3. Several stirring blades 18 are equidistantly arranged on the surface of the rotating rollers 17. The track drive assembly 3 configured at the outer end of the feeding chamber 1 is the power unit for controlling the material conveying. The two rotating rollers 17 symmetrically installed inside the feeding chamber 1 are connected to the transmission structure of the track drive assembly 3. Several stirring blades 18 distributed on the surface of the rotating rollers 17 rotate synchronously with the rotating rollers 17. When medical waste is put into the feeding chamber 1, the track drive assembly 3 starts and drives the two rotating rollers 17 to rotate in the same direction. When the stirring blades 18 rotate with the rotating rollers 17, they break up the clumps and agglomerates of waste on the one hand, and push the material towards the crushing chamber 2 at the lower end of the feeding chamber 1 on the other hand, so as to avoid the accumulation and blockage of waste in the feeding chamber 1, and at the same time achieve uniform material conveying and ensure the feeding stability of the subsequent crushing chamber 2.

[0025] Furthermore, two symmetrical crushing rollers 19 are installed inside the crushing chamber 2. A drive device connected to the two crushing rollers 19 is installed on the outer wall of the crushing chamber 2. When the material from the feeding chamber 1 enters the crushing chamber 2, the drive device starts and drives the two crushing rollers 19 to rotate in opposite directions. By using the shearing and squeezing action of the roller teeth, large and irregular medical waste (such as discarded instruments, dressing packs, etc.) is crushed to a particle size range of 5-20mm, which greatly reduces the volume of waste, increases the contact area between the material and steam, improves the efficiency of the high-temperature sterilization process in the subsequent sterilization chamber 5, and reduces the risk of blockage during the material transportation and degradation process.

[0026] Furthermore, a control valve 4 is installed at the connection between the sterilization chamber 5 and the grinding chamber 2. After the grinding chamber 2 completes the grinding of the material, the control valve 4 receives a signal from the control unit and opens. The ground material falls into the sterilization chamber 5 by its own weight. After all the material has entered the sterilization chamber 5, the control valve 4 closes, making the sterilization chamber 5 a closed space. After the subsequent sterilization process is completed, the control valve 4 opens again in coordination with the feeding rhythm of the conveying pipe 7 to achieve orderly flow of materials.

[0027] Furthermore, steam chambers 6 are connected to both sides of the sterilization chamber 5. Two waste liquid outlets 20 are symmetrically installed on the left and right sides of the lower opening of the sterilization chamber 5. The waste liquid outlets 20 are equipped with filters. Multiple stirring components 21 are rotatably connected inside the sterilization chamber 5. When the material enters the sterilization chamber 5 and the control valve 4 is closed, the steam chamber 6 introduces high-temperature steam at 134℃ and 0.2MPa into the sterilization chamber 5. At the same time, the stirring components 21 are started and rotated at low speed, so that the material is evenly turned over in the chamber and fully contacted with the steam. The condensate generated during the sterilization process flows down the chamber wall to the lower end. After the material is intercepted by the filter, it is temporarily stored in the waste liquid outlet 20. When the humidity sensor in the chamber detects that the humidity exceeds the standard, the solenoid valve of the waste liquid outlet 20 opens to discharge the excess condensate. Through the combination of high-temperature steam and stirring action, the pathogenic microorganisms are killed, while the accumulation of condensate in the chamber affects the sterilization efficiency. The filter can prevent the material from being lost with the waste liquid.

[0028] Furthermore, the conveying pipe 7 is wrapped with a cooling ring plate 22, and a circulation pipe is set inside the cooling ring plate 22. The circulation pipe is connected to an external refrigeration unit. The temperature of the sterilized material is about 80-100℃. When the material enters the conveying pipe 7, the temperature sensor on the inner wall of the conveying pipe 7 monitors the material temperature in real time. If the temperature is higher than 40℃ (the upper limit of the suitable temperature for biodegradation), the control unit will increase the flow rate of the refrigerant in the circulation pipe and use the heat exchange between the cooling ring plate 22 and the conveying pipe 7 to quickly reduce the material temperature.

[0029] Furthermore, a rotating plate 13 is rotatably mounted on the upper end of the central column 12, and a dispensing port 14 is installed on the lower end of the other side of the rotating plate 13. A pipe connected to the dispensing port 14 is provided inside the rotating plate 13. The pipe is connected to an external microbial agent. A quantitative addition valve is provided inside the dispensing port 14. A driving device is provided inside the central column 12 to drive the rotating plate 13 to rotate. The microbial agent is sent into the dispensing port 14 through the pipe inside the rotating plate 13. The dispensing port 14 is located directly above any degradation chamber 16. The dispensing and stopping of the microbial agent can be controlled by the quantitative addition valve.

[0030] Furthermore, an infrared level sensor is installed on the top of the inner wall of the feeding bin 1, and a torque sensor is installed at the shaft of the crushing roller 19 in the crushing bin 2. The infrared level sensor is electrically linked to the track drive assembly 3, and the torque sensor is electrically linked to the drive device of the crushing bin 2. When the infrared level sensor detects that the amount of material in the feeding bin 1 is lower than a preset threshold, it sends a signal to the control unit to start the track drive assembly 3 to drive the rotating roller 17 to rotate and replenish material to the crushing bin 2. When the torque sensor detects that the load torque of the crushing roller 19 exceeds a preset value, the control unit controls the drive device to reduce the speed of the crushing roller 19 and simultaneously suspends the material conveying of the track drive assembly 3. Operation resumes after the load returns to normal. The closed-loop control model of "real-time monitoring → data filtering and processing → deviation calculation → dynamic adjustment → feedback correction → learning iteration" is adopted. Combined with PID regulation, trend prediction and historical data fitting, it breaks through the limitations of traditional single threshold triggering and improves control accuracy and adaptability to operating conditions. Linkage control between infrared level sensor and track drive assembly: Core equation:

[0031] Variable definition: Material level deviation (mm); The effective material level value after filtering (mm); The optimal material level height (mm, default = volume of the feeding bin × 60%).

[0032] Application: To quantify the deviation of the current material level from the ideal range, providing core input parameters for speed regulation.

[0033] Variable definition: The material level change rate (mm / s); The effective material level at the current moment; The effective material level for the previous second; Sampling interval; Application: To predict feed trends (positive for increased feed, negative for decreased feed) and make advance adjustments;

[0034] Variable definition: The real-time rotational speed (m / s) of the track drive. The initial rotational speed (default 0.3 m / s); =0.8 (proportionality coefficient) =0.2 (integral coefficient) =0.1 (differential coefficient); t is the settling time (s); Application: To dynamically offset material level deviations and maintain material level stability through a proportional-integral-differential algorithm; Control logic and feedback mechanism: Initialization settings: Preset optimal material level range

[0035] Real-time adjustment: when <- (Low material level): Increased PID algorithm output, increased track speed Upgraded to a maximum of 1.50 Simultaneously record the adjustment parameters; when > (Material level too high): Rotation speed The lowest it dropped to 0.50 The decline and Positive correlation (the greater the rate of change, the faster the rate of decrease).

[0036] Linkage control between torque sensor and crushing chamber drive unit: Core equation: Variable definition: The effective value of torque (N·m); The sensor samples the data 3 times per second; after removing extreme values, the remaining value is taken as the valid value. Application: To eliminate transient overload noise and obtain accurate load data; Variable definition: The torque change rate (N·m / s); This is the current effective torque; The effective torque is in the first 1 / 3 second; =1 / 3s; Purpose: To distinguish between "instantaneous overload" (mixed with hard objects) and "sustained overload" (excessive material); Tiered Response and Emergency Handling: Normal range: , It is 5 N·m. 30 N·m Warning range: , 45 N·m Rate of change threshold: =5 N·m / s; Emergency handling module: Sensor abnormality: No data for 5 consecutive seconds or a jump of ±20 N·m, initiate redundancy verification (material level is normal but torque is 0 → sensor failure; material level is normal but torque changes abruptly → material jamming). Emergency response to material blockage: Material level continues to rise but < (Without crushing load), start the track to reverse. =0.2m / s) + crushing roller rotates at low speed (30r / min) for 3s to clear blockage.

[0037] Furthermore, a temperature sensor and a pressure sensor are installed on the top of the inner wall of the sterilization chamber 5, and a humidity sensor is installed on the bottom of the inner wall of the sterilization chamber 5. A liquid level sensor is installed inside the waste liquid outlet 20. The temperature sensor, pressure sensor and steam supply valve of the steam chamber 6 are electrically linked. When the temperature sensor detects that the temperature inside the chamber is lower than 134°C, or the pressure sensor detects that the pressure inside the chamber is lower than 0.2MPa, the control unit will open the steam supply valve to supplement high-temperature steam into the sterilization chamber 5. When the humidity sensor detects that the humidity inside the chamber is higher than 60%, it will trigger the solenoid valve of the waste liquid outlet 20 to open and discharge excess condensate. When the liquid level sensor detects that the condensate in the waste liquid outlet 20 reaches the full chamber threshold, it will also start the solenoid valve to drain the liquid, maintaining the high temperature and high pressure environment inside the sterilization chamber 5 in real time to ensure the stability of the sterilization effect. At the same time, the discharge of condensate is automatically controlled to avoid water accumulation in the chamber affecting the uniformity of material sterilization.

[0038] Furthermore, temperature and humidity sensors and material level sensors are installed on the inner wall of the degradation chamber 16, and a temperature sensor is installed on the inner wall of the conveying pipe 7. The temperature sensor of the conveying pipe 7 is electrically linked to the circulation pipe control valve 4 of the cooling ring plate 22. When the temperature sensor on the inner wall of the conveying pipe 7 detects that the material temperature is higher than 40°C, the control unit will increase the opening of the circulation pipe control valve 4 to increase the flow rate of the refrigerant and accelerate cooling. When the material level sensor inside detects that the material has reached the full threshold, the control unit will activate the electric push rod 15 to pull the degradation chamber 16 back to its initial position along the side groove 11. At the same time, the stepper motor will be activated to drive the rotating disk 9 to rotate, switching the unloaded degradation chamber 16 to the position corresponding to the discharge end of the conveying pipe 7. When the temperature and humidity sensor inside the degradation chamber 16 detects that the temperature and humidity deviate from the suitable range (temperature 55-65℃, humidity 50-60%), it will control the speed of the stirring shaft inside the degradation chamber 16 and adjust the material turning frequency to maintain environmental stability. It should be noted that the conveying pipe 7 and the degradation chamber 16 are connected by a snap-fit ​​connection and sealed with a sealing ring.

[0039] The usage method of this embodiment is as follows: Before use, check the connection and sealing status of each module, confirm that each sensor and drive component is powered normally, open the feeding chamber 1, put the medical waste into the chamber, and start the track drive component 3. The rotating roller 17 drives the stirring blade 18 to rotate, breaking up the clumps of material and pushing it smoothly to the crushing chamber 2; the drive device of the crushing chamber 2 is then started, and the crushing rollers 19 rotate in opposite directions to shear and reduce the volume of the material. After completion, the control valve 4 automatically opens, and the material falls into the sterilization chamber 5 by its own weight. Then the control valve 4 closes to form a closed space in the sterilization chamber 5. The steam chamber 6 introduces high-temperature steam into the sterilization chamber 5, while the stirring component 21 rotates at low speed to allow the material to come into uniform contact with the steam to achieve sterilization; the condensate generated during the process is intercepted by the filter screen and automatically discharged from the waste liquid outlet 20. After sterilization, control valve 4 opens in coordination with the feeding rhythm of conveying pipe 7, allowing material to enter the conveying pipe 7. The auger conveyor in the conveying pipe 7 pushes the material forward, and cooling ring plate 22 automatically adjusts the cooling capacity according to the material temperature to cool the material to a suitable degradation environment temperature. The electric push rod 15 controls any degradation chamber 16 to move and connect with the conveying pipe 7. Then, rotating plate 13 is adjusted to the corresponding position, and the quantitative addition valve automatically injects bacterial agent simultaneously. When the degradation chamber 16 is full, the electric push rod 15 pulls the degradation chamber 16 to reset, and rotating plate 9 drives installation plate 10 to switch the empty degradation chamber 16 to the discharge end of the conveying pipe 7 to continue receiving material. During the degradation process, the device automatically adjusts the stirring rhythm to maintain a suitable temperature and humidity environment, ultimately completing the harmless treatment of medical waste.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
