Description

Technical Field

[0001] This utility model belongs to the field of medical waste treatment technology, specifically relating to an automated medical waste treatment device. Background Technology

[0002] According to the "Regulations on the Management of Medical Waste," the state promotes centralized and harmless disposal of medical waste and encourages research and development of relevant technologies for the safe disposal of medical waste. Currently, medical waste disposal centers in China with a disposal capacity of more than 10 t / d mainly adopt centralized incineration. The feeding and cleaning / disinfection of medical waste incineration containers are mostly carried out semi-automatically or manually. Early domestic automatic feeding systems for medical waste incineration required manual feeding of medical waste containers into the conveyor line at the front end and manual feeding of the cleaned containers into the temporary storage area at the back end.

[0003] Some experts have developed equipment that cleans and disinfects the transfer containers immediately after medical waste is unloaded. This method requires manual feeding of the medical waste into an elevator, which then lifts the waste to the inlet for unloading. The transfer containers then return, undergoing cleaning and disinfection during the return process. Finally, the containers are manually removed from the elevator and outlet. All of these medical waste feeding operations require some degree of human intervention and cannot completely prevent contact between personnel and medical waste, posing a certain negative impact on the health of on-site workers. Especially during outbreaks of acute infectious diseases, the large amounts of epidemic-related waste generated place a heavy burden on the ecological environment and present a severe challenge to medical waste disposal companies. Furthermore, the processes of medical waste feeding and transfer container cleaning and disinfection are cumbersome, requiring significant manpower and exhibiting low production efficiency.

Each transfer and rotating component includes a support plate, an electrically powered slide rail mounted on the support plate, and a rotating component connected to the slide rail. Each rotating component includes a turntable, a robotic arm fixedly connected to the turntable, and a servo motor. A pushing component is provided at the kiln head of the rotary kiln and at the end of the third roller conveyor near the second rotary conveyor, and a connecting conveyor line is connected to the end of the third roller conveyor near the second rotary conveyor.

[0007] Preferably, both the first and second vertical conveyors are continuous vertical conveyors with a corrugated sidewall belt structure.

[0008] Furthermore, a spray system is installed in the rinsing chamber, and a 90°C high-temperature steam sterilization device is installed in the disinfection chamber. The spray system includes multiple nozzles, and the spray liquid is water containing disinfectant.

[0009] Preferably, photoelectric sensors and weight sensors are installed on the feeding conveyor and the return conveyor.

[0010] Furthermore, the PLC control cabinet is electrically connected to the hoist, feeding conveyor, pushing assembly, return conveyor, cleaning and disinfection machine, transfer rotating assembly and connecting conveyor, as well as photoelectric sensor and weight sensor.

[0011] Furthermore, the actuating component includes a cylinder and a movable block connected to the telescopic rod of the cylinder.

[0012] Preferably, the robotic arm that transfers the rotating component is a four-jaw pneumatic gripper, and the turntable can rotate 360°.

[0013] Furthermore, the connecting conveyor line connects the second roller conveyor line and the third roller conveyor.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The device achieves fully automated operation of the entire process of medical waste treatment, from unloading, conveying, feeding, and returning to the container, to cleaning, disinfection, and stacking, through the coordinated operation of modules such as the elevator, feeding line, and return container. Operators do not need to directly contact medical waste, eliminating the risk of infection at the source; at the same time, the efficient operation of equipment such as continuous vertical conveyors and rotary conveyors improves the efficiency of medical waste treatment.

[0016] The photoelectric sensors and weight sensors on the feeding conveyor and return conveyor are linked with the PLC control cabinet in real time to automatically monitor the process. When the empty bucket is overweight, the connecting conveyor automatically starts and pushes the components to complete the return unloading, ensuring thorough unloading. The cleaning and disinfection machine adopts a partitioned design of "rinsing chamber + disinfection chamber" and is equipped with a 180° flipping mechanism, so that water containing disinfectant and 90° high-temperature steam can fully cover the inner and outer surfaces of the turnover bucket.

[0027] like Figure 1-4 As shown, this utility model relates to an automated medical waste treatment device, comprising a hoist 1, a feeding conveyor line 2, a rotary kiln 3, a return container conveyor line 4, a cleaning and disinfection machine 5, a stacking machine 6, and a PLC control cabinet. The feeding conveyor line 2, connected to the hoist 1, includes a first roller conveyor line 21, a first vertical conveyor 22, a second roller conveyor line 23, and a first rotary conveyor 24 connected in sequence. After the hoist 1 lifts the medical waste containers to the temporary storage area platform, the containers are conveyed by the first roller conveyor line 21, lifted by the first vertical conveyor 22 to the height of the feeding platform, and then conveyed to the rotary kiln 3 by the second roller conveyor line 23 and the first rotary conveyor 24.

[0028] In this embodiment, the return conveyor line 4 includes a second rotary conveyor 41, a third roller conveyor 42, a second vertical conveyor 43, and a fourth roller conveyor 44 connected in sequence. Empty turnover drums are conveyed by the second rotary conveyor 41 and the third roller conveyor 42, descended by the second vertical conveyor 43 to the height of the cleaning and disinfection machine 5, and then conveyed to the cleaning and disinfection machine 5 by the fourth roller conveyor 44.

[0029] In this embodiment, the cleaning and disinfection machine 5 is installed on the fourth roller conveyor 44 and is divided into a rinsing chamber 51 and a disinfection chamber 52.

[0032] In this embodiment, a pushing assembly 31 is provided at the kiln head of the rotary kiln 3 and at one end of the third roller conveyor 42 near the second rotary conveyor 41. The pushing assembly 31 includes a cylinder 312 and a moving block 313 connected to the telescopic rod of the cylinder 312. The moving block 313 has a groove in the middle and is connected to a connecting block 314 by a spring 315. The surface of the connecting block 314 is provided with a rubber pad. When the pushing assembly 31 is used to introduce medical waste into the rotary kiln 3, when the robotic arm 74 flips the turnover bucket, it is driven by the cylinder 312 to pat the outside of the turnover bucket, so that the medical waste is emptied cleanly. The pushing assembly 31 also plays a certain pushing role on the return conveyor line 4. The surface of the connecting block 314 connected by the spring 315 is also provided with a rubber pad, which can play a buffering role during patting and prevent damage to the turnover bucket.

[0033] In this embodiment, the third roller conveyor 42 is connected to a connecting conveyor line 8 at one end near the second rotary conveyor 41. The connecting conveyor line 8 connects the second roller conveyor line 23 and the third roller conveyor 42, and is used to achieve return when the turnover drum is overloaded.

[0034] In this embodiment, both the first vertical conveyor 22 and the second vertical conveyor 43 are continuous vertical conveyors with a corrugated sidewall belt structure, which can stably lift and lower the turnover drum.

[0035] In this embodiment, a spray system is installed in the rinsing chamber 51, and a 90°C high-temperature steam sterilization device is installed in the disinfection chamber 52. The spray system includes multiple nozzles, and the spray liquid is water containing disinfectant, which can thoroughly rinse and disinfect the turnover bucket.

[0036] In this embodiment, photoelectric sensors and weight sensors are installed on the feeding conveyor line 2 and the return conveyor line 4. The PLC control cabinet is electrically connected to the hoist 1, the feeding conveyor line 2, the pushing assembly 31, the return conveyor line 4, the cleaning and disinfection machine 5, the transfer and rotation assembly 7, and the connecting conveyor line 8, as well as the photoelectric sensors and weight sensors, to control the operation of the entire device, display system images in real time, adjust operating parameters, and perform fault diagnosis.

[0037] Working principle:

[0038] After the medical waste container is transported to the disposal unit, the elevator 1 lifts it to the temporary storage area platform. The robotic arm 74 of the transfer rotating assembly 7 grabs the container and places it on the first roller conveyor line 21. After the photoelectric sensor detects that the container is in place, the roller conveyor motor starts, and the container is sequentially lifted by the first vertical conveyor 22, conveyed by the second roller conveyor line 23 and the first rotary conveyor 24 to the kiln head of the rotary kiln 3.

[0039] At the kiln head of rotary kiln 3, the robotic arm 74 of the rotating conveyor assembly 7 grabs the turnover drum. The servo motor starts, rotating the turnover drum 90°. The slide rail 72 starts, placing the turnover drum 3 on the medical waste hopper of rotary kiln 3. It is then pushed into the assembly 31, and driven by the cylinder 312, the outside of the turnover drum is patted to empty the medical waste completely. After processing, the empty turnover drum enters the return conveyor line 4, and is then transported by the second rotary conveyor 41 and the third roller conveyor 42.

[0040] On the third roller conveyor 42, a weight sensor detects the weight of the empty turnover drum. If the empty turnover drum is detected to be overweight, the PLC control cabinet controls the connecting conveyor line 8 to open, and the pushing component 31, under the continuous pushing of the cylinder 312, the empty turnover drum flows back to the feeding conveyor line 2 via the connecting conveyor line 8 for re-unloading. If the weight is normal, the empty turnover drum is lowered by the second vertical conveyor 43 to the height of the cleaning and disinfection system, and then conveyed by the fourth roller conveyor 44 to the front of the cleaning and disinfection machine 5. The transfer rotating component 7 grabs the empty turnover drum, the servo motor starts, rotates the turnover drum 180°, and then lowers the turnover drum into the cleaning and disinfection machine 5.

[0041] Inside the cleaning and disinfection machine 5, empty turnover drums first enter the rinsing chamber 51, where they are rinsed and disinfected by the spray system. Then they enter the disinfection chamber 52, where they are disinfected by a 90℃ high-temperature steam disinfection device. After cleaning and disinfection, the empty turnover drums are picked up by the transfer and rotating assembly 7, and the servo motor continues to start, rotating the turnover drums 180° to restore their original shape. They are then placed on the stacking machine 6 for storage and stacking. After stacking, they are sent to the empty turnover drum temporary storage area.

[0042] In use, the operation is controlled by a PLC control cabinet and can be monitored in real time through various sensors without human intervention. Furthermore, in this new experimental device, some components such as the hoist 1 and the conveyor are existing technologies, and their specific structures will not be described in detail.
