Description

Technical Field

[0001] This invention relates to the field of drum washing machine technology, specifically to a stand-alone internal and external drum washing machine for medical waste. Background Technology

[0002] Medical waste transfer bins are special containers used by medical institutions to collect and transport infectious medical waste. Traditional medical waste washing devices are mainly used to clean and disinfect the transfer bins after use, remove residual medical waste, bloodstains and germs from the bins, prevent cross-infection, and ensure the hygiene and safety of medical waste transportation. They are an indispensable key equipment in the harmless treatment process of medical waste.

[0003] However, in the high-risk, high-hygiene-standard operating environment of medical waste treatment centers, traditional medical waste washing equipment has a low degree of automation and relies heavily on manual labor for operations such as loading, turning, and unloading. Operators have to directly contact contaminated medical waste bins, posing a very high risk of infection. In addition, manual operation is inefficient and cannot meet the continuous processing needs of large quantities of medical waste bins. Furthermore, the cleaning effect is unstable, and it often uses a single internal rinsing method, which cannot achieve simultaneous and thorough cleaning of the inside and outside of the bin. Moreover, the bins are not securely fixed and are prone to shaking and displacement during the cleaning process. In addition, the lack of precise control over the disinfectant ratio makes it difficult to guarantee a stable disinfection effect, posing potential hygiene and safety hazards. Summary of the Invention

[0004] This invention provides a stand-alone internal and external drum washing machine specifically for medical waste, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A stand-alone internal and external drum washing machine for medical waste includes: a water supply mechanism comprising a water storage tank, a water inlet pipe at the top of the water storage tank, and a water outlet pipe on one side of the bottom of the inner cavity of the water storage tank; a first tilting mechanism comprising a mounting frame, a first chain conveyor fixedly connected inside the mounting frame, and a mounting bracket fixedly connected to the top of the first chain conveyor frame; a cleaning mechanism comprising a second chain conveyor, a fixing component, an internal drum cleaning component, and an external drum cleaning component, wherein the second chain conveyor is disposed on one side of the feeding mechanism, the fixing component is fixedly installed on both sides of the second chain conveyor frame, the internal drum cleaning component is fixedly installed inside the second chain conveyor frame, and the external drum cleaning component is fixedly installed directly above the internal drum cleaning component; and a discharge mechanism fixedly connected to the end of the cleaning mechanism, comprising a second tilting mechanism having the same structure as the first tilting mechanism, and a third chain conveyor disposed on one side of the second tilting mechanism.

[0013] A further improvement of the technical solution of the present invention is that the fixing components are symmetrically arranged on both sides of the second chain conveyor frame. When the medical waste bin to be cleaned is transported to the cleaning station, the second cylinders on both sides extend synchronously, driving the clamping component to rotate around its rotation axis with the second chain conveyor frame.

Through the sequential linkage of a first tilting mechanism, a second chain conveyor, a third chain conveyor, and a robotic arm, it automatically completes continuous operations of loading and tilting, conveying and positioning, cleaning and disinfection, tilting and uprighting, and stacking and unloading. The entire process eliminates the need for direct human contact with contaminated medical waste containers, completely eliminating the risk of cross-infection for operators. The processing efficiency is significantly improved compared to manual operation, while also significantly enhancing the stability of the cleaning and disinfection effect. The machine employs a simultaneous spray pattern inside the container and fan-shaped cleaning nozzles outside, achieving thorough cleaning inside and outside the container without any blind spots. Symmetrical fixing components on both sides elastically clamp the container body to prevent shaking and displacement during cleaning.

It is used to store medical disinfectants such as chlorine-containing disinfectants; the metering pump 15 is an electromagnetic diaphragm metering pump with a metering accuracy of ±1% and a flow rate adjustment range of 0-5L / min.

[0036] Example 3, as Figures 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the external cleaning assembly includes a fourth cylinder 39, the output end of which is fixedly connected to a lifting frame 310, and a cleaning nozzle 311 is fixedly connected to the surface of the lifting frame 310. The interior of the cleaning nozzle 311 is connected to the interior of the water supply pipe 17 through a branch pipe. A support frame 43 is fixedly connected to one side of the end of the third chain conveyor 42, and a robotic arm 44 is fixedly connected to the top of the support frame 43. A pneumatic gripper 45 is fixedly connected to the output end of the robotic arm 44, and a discharge conveyor 46 is provided on the side of the robotic arm 44. The fixing components are symmetrically arranged on both sides of the frame of the second chain conveyor 31. When the medical waste bin 28 to be cleaned is transported to the cleaning station, the second cylinders 33 on both sides extend synchronously, driving the clamping member 34 to rotate around its rotation axis with the frame of the second chain conveyor 31. The medical waste bin is elastically clamped by the rubber buffer pad 35 at the end to prevent the bin from shaking or shifting during the cleaning process. The cleaning components inside and outside the bin are started synchronously. The third cylinder 37 drives the spray nozzle 38 to rise to the middle of the inner cavity of the medical waste bin 28 to be cleaned. The fourth cylinder 39 drives the lifting frame 310 to descend to 5-10cm above the opening of the medical waste bin 28 to be cleaned. The spray nozzle 38 sprays water in a 360° rotating manner to rinse the inner wall of the bin. The cleaning nozzle 311 sprays water in a fan shape to rinse the outer wall and bottom of the bin. The first tilting mechanism, the second chain conveyor 31, the fixing component, the cleaning components inside and outside the bin, the second tilting mechanism 41, the third chain conveyor 42 and the robotic arm 44 are linked in sequence to realize the automatic feeding and tilting, conveying and positioning, synchronous cleaning inside and outside, tilting and uprighting, and automatic stacking and unloading of the medical waste bin.

[0037] It should be noted that: the fourth cylinder 39 is a double-acting cylinder with a stroke of 300mm and a thrust of 500N, used to drive the lifting frame 310 to move up and down; the lifting frame 310 is welded from rectangular steel pipes, with a portal-shaped structure, spanning above the second chain conveyor 31, used to install and fix the cleaning nozzles 311; there are a total of 8 cleaning nozzles 311, arranged in two rows, with a spray angle of 120° fan shape, and a flow rate of 2L / min per nozzle, used to rinse the outer wall and bottom of the medical waste bin in a fan-shaped spray pattern; the support frame 43 is welded from 100×100mm square steel.

[0038] In this embodiment, by adding an external cleaning component, synchronous, thorough cleaning of the inner and outer walls of the medical waste bin is achieved, with the cleaning time adjustable between 30 and 60 seconds. A PLC control system enables precise timing linkage between various mechanisms, completing a fully automated process from automatic feeding and tilting, conveying and positioning, synchronous internal and external cleaning, tilting and uprighting, to automatic stacking and unloading. This completely eliminates the risk of cross-infection from direct contact between operators and contaminated medical waste bins. The processing efficiency is significantly improved compared to traditional manual operation, fully meeting the needs of large-volume, high-hygiene-standard, and continuous operations in medical waste treatment centers.

[0039] The working principle of this independent internal and external drum washing machine for medical waste will be explained in detail below.

[0040] like Figures 1-10 As shown, after the system is powered on, the PLC control system first performs a self-test to confirm that all sensors, cylinders, motors, and pumps are working properly. The medical waste bin 28 to be cleaned is placed at the entrance of the first chain conveyor 22 by manual or automatic conveyor line. After the photoelectric sensor detects the bin, the first chain conveyor 22 starts and smoothly transports the medical waste bin to the flipping station of the first flipping mechanism.

[0041] Upon reaching the flipping station, the first cylinder 26 drives the two clamping plates 27 to extend synchronously and clamp the body of the medical waste bin; the flipping motor 24 starts, driving the flipping frame 25 to flip smoothly 180°, so that the mouth of the medical waste bin faces downward and the remaining medical waste and accumulated liquid inside the bin are poured out; after the flipping is completed, the flipping motor 24 reverses, driving the flipping frame 25 to reset, the first cylinder 26 retracts, and the clamping plates 27 are released.

[0042] The first chain conveyor 22 restarts, transporting the medical waste bin with its opening facing down to the second chain conveyor 31, and then to the cleaning station. Once the photoelectric sensor at the cleaning station detects that the bin has arrived in place, the second chain conveyor 31 stops operating; at this time, the second cylinders 33 on both sides extend synchronously, driving the clamping parts 34 to rotate around the shaft, and elastically clamping the medical waste bin body through the rubber buffer pads 35 at the ends, completing the precise positioning and fixing of the bin.

[0043] Subsequently, the delivery pump 16 starts, drawing clean water from the storage tank 11. Simultaneously, the metering pump 15 pumps chlorine-containing disinfectant from the disinfectant storage tank 14 into the outlet pipe 13 at a preset ratio of 1:100. The disinfectant mixes in the pipe to form disinfectant cleaning water, which is then delivered to the shower spray plate 38 and the cleaning nozzles 311 via the water supply pipe 17. The third cylinder 37 drives the shower spray plate 38 to rise to the middle of the medical waste bin's inner cavity, using a 360° rotating spray to high-pressure rinse the inner wall of the bin. The fourth cylinder 39 drives the lifting frame 310 to descend to 8cm above the bin opening, where eight fan-shaped cleaning nozzles 311 spray simultaneously to rinse the outer wall and bottom of the bin. The internal and external cleaning is carried out simultaneously for 45 seconds.

[0044] After cleaning, the conveying pump 16 and the metering pump 15 stop running, the third cylinder 37 and the fourth cylinder 39 retract, driving the shower spray plate 38 and the lifting frame 310 to reset; the second cylinder 33 retracts, and the fixing component loosens the barrel; the second chain conveyor 31 starts, transporting the cleaned medical waste barrel to the discharge mechanism.

[0045] The second flipping mechanism 41 repeats the action of the first flipping mechanism, flipping the medical waste bin back to its upright position, and is then transported to the unloading station by the third chain conveyor 42. Once the photoelectric sensor at the unloading station detects that the bin is in place, the third chain conveyor 42 stops operating; the robotic arm 44 drives the pneumatic gripper 45 to move above the bin opening, clamping the edge of the opening, lifting the medical waste bin, and neatly stacking it onto the discharge conveyor 46 according to a preset program, with a stacking height of up to 3 layers. After stacking is complete, the discharge conveyor 46 starts, transporting the stacked medical waste bins to the medical waste bin cleaning and storage area, completing the entire cleaning process.

[0046] The system's various mechanisms achieve precise timing linkage through PLC control, are equipped with multiple safety protection devices, can operate continuously for 24 hours without manual intervention, and effectively ensure the safety of operators and the stable operation of equipment.

[0047] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

When the medical waste bin (28) to be cleaned is transported to the cleaning station, the second cylinders (33) on both sides extend synchronously, driving the clamping component (34) to rotate around its rotation axis with the frame of the second chain conveyor (31). The rubber buffer pad (35) at the end elastically clamps the body of the medical waste bin to prevent the bin from shaking or shifting during the cleaning process.

9. A stand-alone internal and external drum washing machine for medical waste as described in claim 1, characterized in that: The cleaning components inside and outside the bucket are started simultaneously. The third cylinder (37) drives the spray nozzle (38) to rise to the middle of the inner cavity of the medical waste bucket (28) to be cleaned. The fourth cylinder (39) drives the lifting frame (310) to descend to 5-10cm above the opening of the medical waste bucket (28) to be cleaned. The spray nozzle (38) sprays in a 360° rotating manner to rinse the inner wall of the bucket, and the cleaning nozzle (311) sprays in a fan shape to rinse the outer wall and bottom of the bucket.

10. A stand-alone internal and external drum washing machine for medical waste as described in claim 1, characterized in that: The first flipping mechanism, the second chain conveyor (31), the fixed component, the inner cleaning component, the outer cleaning component, the second flipping mechanism (41), the third chain conveyor (42) and the robotic arm (44) are linked in sequence to realize the automatic feeding and flipping, conveying and positioning, synchronous cleaning inside and outside, flipping and uprighting, and automatic stacking and unloading of medical waste bins.
