Description

TECHNICAL FIELD

[0001] The present application relates to the field of sterile cloth cleaning, in particular to a bubble and ultrasonic wave assisted sterile cloth cleaning method and device. BACKGROUND

[0002] The fundamental contradiction faced by current sterile cloth cleaning technology is due to the structural defects of the two mainstream technical paths. In the pursuit of cleaning effect and protection of cloth, the existing technical solutions all show obvious limitations between the two opposing targets.

[0003] Traditional mechanical extrusion cleaning technology, including roller extrusion, brush friction, high-pressure water jet, etc., realizes stain removal through direct physical contact and mechanical force. Although it can guarantee the basic cleanliness index, this contact cleaning mechanism will cause progressive damage to the micro-fiber structure of the sterile cloth. Under the repeated mechanical stress, the cotton or blended sterile cloth will show irreversible damage such as fiber breakage, surface pilling and fabric thinning, which not only significantly shortens the service life of this high-value consumable, increases the use cost, but also causes potential risks to the subsequent sterility and functionality of the sterile cloth.

[0004] And another type of non-contact technology represented by pure ultrasonic cleaning, although it avoids mechanical friction, its cleaning mechanism has inherent limitations and is difficult to achieve complete removal of complex stains. Ultrasonic cleaning mainly relies on cavitation effect to generate micro-bubbles in liquid and break them, and its action range and intensity are obviously restricted by frequency and power: low-frequency ultrasonic waves can produce strong cavitation effect, but the energy distribution is uneven, which is easy to form cleaning blind area on the surface of the cloth, and the penetration force is insufficient for organic stains such as oil and protein embedded in the deep part of the fiber; high-frequency ultrasonic waves can improve the uniformity of the action, but the cavitation intensity is weak, and the stripping ability for firmly adhered particle type stains is limited. In addition, single frequency ultrasonic waves are difficult to deal with mixed pollution composed of stains of different particle sizes and different adhesion properties at the same time, resulting in incomplete cleaning and obvious residue. SUMMARY

[0005] In order to overcome the technical defects of mechanical damage and cleaning residue, the present application provides a bubble and ultrasonic wave assisted sterile cloth cleaning method and device.

[0012] Preferably, a drying assembly is further arranged, and the drying assembly is reversibly installed on the outer surface of the top cover of the cleaning tank.

[0016] Preferably, each cleaning area of the composite stain removal module corresponds to an independent liquid supply pipeline and a drain, and the drain is located at the lowest point of the inclined surface of the installation wedge-shaped seat, for directly draining the sewage after cleaning of the current cleaning area, thereby preventing cross contamination caused by backflow of the sewage.

[0017] Preferably, the cleaning tank uses ultrapure water or water for injection during the cleaning process.

DETAILED DESCRIPTION

[0037] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0038] As Figures 1-5As shown, the present invention discloses a sterile fabric cleaning device using bubble-assisted ultrasonic waves, comprising a cleaning tank, characterized in that: a wedge-shaped cleaning track is installed in the cleaning tank; a fabric conveying device is provided on the wedge-shaped cleaning track, the fabric conveying device being able to pull the fabric to be cleaned from the bottom of the wedge-shaped cleaning track and climb up the slope of the wedge-shaped cleaning track; multiple composite stain removal modules are evenly arranged on the slope of the wedge-shaped cleaning track, the composite stain removal modules including a composite frequency ultrasonic wave generating module and a microbubble generating module, the composite frequency ultrasonic wave generating module generating ultrasonic waves to shake off or loosen stains inside and outside the fabric, and the microbubble generating module generating bubbles that penetrate the fabric and carry out the stains inside the fabric.

[0039] Furthermore, a rinsing device is provided on the upper part of the wedge-shaped cleaning track slope, which can wash away stains on the fabric surface from the slope.

[0040] Furthermore, the cleaning tank is provided with a top cover, and the top cover has a fabric inlet / outlet groove; the guide roller is installed inside the cleaning tank, the axis of the guide roller is parallel to the fabric inlet / outlet groove, and part of its roller body protrudes from the inner surface of the top cover; when the top cover is closed, the sterile cloth is clamped between the pressing mechanism and the guide roller, and can be pulled and guided along the circumference of the guide roller during the cleaning process; a rotary encoder is connected to the rotating shaft of the guide roller to detect the moving length or speed of the sterile cloth during the cleaning process in real time.

[0041] The combination of guide rollers and pressing mechanism enables a smooth and controllable path for the fabric within the equipment. In particular, the introduction of a rotary encoder allows the equipment to monitor the fabric's movement (length / speed) in real time. This not only provides a data foundation for automatic control (such as calculating cleaning time and locating stained areas) but also facilitates the quantification and traceability of the cleaning process, enhancing the equipment's intelligence and process controllability.

[0042] Furthermore, it also includes a control panel, which is electrically connected to the composite frequency ultrasonic generator module and the microbubble generator module respectively, for coordinating the control of the frequency, power, working mode of the ultrasonic waves and the injection parameters of the microbubbles; the control panel has multiple cleaning programs pre-stored, and the cleaning programs define the ultrasonic frequency combination, power curve, and target particle size and injection flow rate of the microbubbles for different pollution levels or fabric materials.

[0043] By integrating a control panel and preset cleaning programs, the complex multi-parameter coordination (ultrasonic frequency, power, bubble size, flow rate) operation is simplified and standardized. Users only need to select the fabric type or contamination level to automatically select the optimal parameter combination, greatly reducing the difficulty of operation and professional requirements, ensuring the consistency and repeatability of cleaning results, and making advanced technology easy to popularize and apply.

[0044] Furthermore, it also includes a drying assembly, which is rotatably mounted on the outer surface of the top cover of the washing tank; when drying is required, the drying assembly can be rotatably opened to form a drying chamber with a receiving space for receiving and accommodating the fabric output from the washing tank; the drying assembly is equipped with a heating unit and an airflow circulation unit inside to dry the fabric contained therein.

[0045] By integrating a tumble dryer, continuous operation of "washing-dehydration-drying" is achieved. This avoids the risk of secondary environmental contamination of wet cloths during transfer, shortens the overall cleaning process time, improves equipment space utilization and operational efficiency, and provides users with a closed-loop complete solution.

[0046] Furthermore, the angle between the upper inclined surface of the mounting wedge and the horizontal plane is 45° to 75°, each cleaning area of ​​the composite cleaning module has an equal length, and the ultrasonic frequency and bubble particle size parameters between adjacent areas change in a stepwise manner.

[0047] By limiting the angle of the inclined plane (45°-75°), the optimal balance between smooth stain sliding and stable fabric transport / adhesion was found. By specifying equal cleaning zone lengths and stepwise parameter variations, a gradual and gradient treatment of stains was achieved, similar to multiple fine processes on an assembly line, from coarse to fine. This effectively handles large stains without damaging the fabric, optimizing energy distribution and the smoothness of the cleaning effect transition.

[0048] Furthermore, each cleaning area of ​​the composite cleaning module corresponds to an independent liquid supply pipeline and a drain outlet. The drain outlet is located at the lowest point of the inclined surface of the mounting wedge seat, which is used to directly discharge the wastewater after cleaning this section to prevent cross-contamination from wastewater backflow.

[0049] By setting up independent water supply and drainage systems for each cleaning area, a segmented counter-current or independent water tank cleaning mode is achieved. This effectively prevents upstream dirty water from flowing back and contaminating the initially cleaned fabric downstream, implementing the concept of "preventing secondary pollution" in every cleaning step and greatly improving the final overall cleanliness.

[0050] Furthermore, the cleaning tank uses ultrapure water or water for injection during the cleaning process;

[0051] The micro-nano bubble generator is connected to a gas regulating unit, which can inject a mixture of air, ozone, or inert gas in different proportions into the cleaning liquid according to the selected cleaning program, so as to generate bubbles with specific oxidation or inertization cleaning functions.

[0052] The chemical functions of micro- and nano-bubbles are expanded through a gas regulation unit. Injecting ozone enables strong oxidative sterilization and disinfection; injecting inert gases (such as nitrogen) generates more stable bubbles with stronger implosion energy, enhancing physical cleaning effects or protecting sensitive fabrics. This makes the cleaning process not only reliant on physical forces but also adds controllable chemical-assisted cleaning or fabric protection functions, broadening its application scenarios and making cleaning strategies more flexible.

[0053] Furthermore, the control panel also includes a self-learning module, which can automatically optimize and generate new cleaning program parameters based on the user's historical cleaning effect ratings for different fabrics. These parameters represent the sterile fabric cleaning parameters of the bubble-coordinated ultrasonic wave of the present invention.

[0054] By introducing a self-learning module, the equipment gains the ability to continuously optimize and personalize. It can automatically fine-tune cleaning parameters based on actual usage feedback (user ratings), enabling the cleaning program to adapt to the specific needs of different users, differences in water quality, or subtle changes in fabric. This represents a leap from "preset programs" to "intelligent optimization," enhancing the equipment's intelligence level and long-term user satisfaction.

[0055] The method for cleaning fabric using the cleaning module of the present invention includes the following steps:

[0056] S1. Fabric feeding and stain separation: The fabric to be cleaned is conveyed upward along the inclined surface of the wedge-shaped cleaning module, and the composite stain removal module is activated at the same time, so that the stains detached from the fabric slide down the inclined surface to the bottom of the cleaning tank.

[0057] S2. Segmented Composite Cleaning: The fabric is cleaned segment by segment using the multi-segmented composite cleaning module, wherein:

[0058] Low-frequency ultrasound combined with micron-sized large bubbles acts on the fabric surface to remove large particles and adherent stains.

[0059] High-frequency ultrasound combined with nano-sized microbubbles penetrates into the fabric fibers to remove deep, fine stains.

[0060] S3. Fabric recycling and prevention of secondary pollution: After washing, the fabric changes its running direction at the support roller and is retracted into the washing tank to avoid contact with the slipped dirt again.

[0061] S4. Fabric drying process: The cleaned fabric is output to the drying assembly, the drying chamber is closed and the heating and airflow circulation are started to dry the fabric.

[0062] Example 1:

[0063] This embodiment provides a basic implementation of the bubble-coordinated ultrasonic sterile cloth cleaning device of the present invention.

[0064] Equipment structure integration points:

[0065] The cleaning equipment has a streamlined structure, mainly consisting of a stainless steel cleaning tank, a hinged top cover with a sealing strip, a core wedge-shaped cleaning module, and a basic control system. Its core cleaning module integrates the following features: the mounting wedge is made of corrosion-resistant engineering plastic, with its upper inclined surface forming a 60° angle with the horizontal plane; three composite cleaning modules are evenly embedded on its inclined surface, each containing a transducer capable of generating 40kHz / 120kHz dual-frequency ultrasonic waves and a micro-nano bubble generator capable of generating adjustable bubbles from 10 micrometers to 100 nanometers; a support roller is located at the sharp end of the wedge to guide the fabric towards recycling.

[0066] Workflow:

[0067] First, the operator guides the fabric to be cleaned to the inclined surface of the cleaning module. After the equipment is started, the fabric undergoes three stages of treatment: the first stage uses 40kHz ultrasonic waves and micron-level bubbles to powerfully remove large stains from the surface, and the dirt slides off with the water flow; the second stage switches to dual-frequency mixed ultrasonic waves and submicron-level bubbles for medium cleaning; the third stage uses pure 120kHz ultrasonic waves and nano-bubbles to penetrate deep into the fibers to remove microorganisms and fine residues; finally, the clean fabric is turned at the support roller and guided into the clean area of ​​the tank for collection, separating it from dirt throughout the process.

[0068] The effect of this embodiment is that it achieves gradient cleaning of sterile cloth from the surface to the inside and from coarse to fine. The physical cleaning method avoids chemical residues, and the wedge structure design effectively separates dirt from clean cloth, meeting the basic requirements for sterile cloth reprocessing.

[0069] Example 2:

[0070] Based on Example 1, this embodiment integrates intelligent control, directional air supply, and independent sewage discharge functions to process linens of different pollution levels in batches.

[0071] Equipment structure integration points:

[0072] The device in this embodiment integrates multiple functions in its structure. First, a pair of guide conveyor belts are symmetrically integrated on both sides of the inclined surface of the mounting wedge-shaped seat of the cleaning module for automatic clamping and pulling of the fabric. Second, the control system has been upgraded to an intelligent panel with pre-stored multiple cleaning programs, and can be linked with the gas regulating unit to inject a mixture of air and ozone into the microbubble generating module. Most importantly, to achieve more thorough cleaning, each section of the composite decontamination module is equipped with an independent liquid supply pipeline and a drain outlet located at the lowest point of the inclined surface of that section, realizing unidirectional segmented flow and immediate discharge of cleaning water, eliminating cross-contamination.

[0073] Workflow:

[0074] The workflow is an intelligent, programmed cleaning process. After the operator selects the "heavy contamination" program, the equipment operates fully automatically: the conveyor belt feeds and positions the fabric; then the fabric passes through three independently supplied and discharged cleaning zones in sequence—the first zone uses 40kHz ultrasound and high-concentration micron bubbles for a powerful pre-cleaning process for 2 minutes, with the wastewater being directly discharged; the second zone uses composite frequencies and ozone-containing submicron bubbles for deep cleaning and oxidation for 1.5 minutes; the third zone uses pure high-frequency ultrasound and high-concentration ozone nanobubbles for final penetration sterilization and rinsing for 1.5 minutes; after cleaning, the fabric is guided by support rollers to fall into the clean collection basket.

[0075] The advantages of this embodiment are: the standardization and optimization of the cleaning process are achieved through programmed control; the introduction of ozone bubbles provides an additional chemical sterilization effect; the independent supply and drainage system greatly improves the utilization rate of cleaning water and ensures the independence of each cleaning stage, making it particularly suitable for treating high-risk pollutants.

[0076] Example 3:

[0077] This embodiment demonstrates the fully automated workstation form of the present invention, which is highly integrated with drying function, process monitoring and self-learning system, and is suitable for sterile fabric production or recycling enterprises with extremely high requirements for cleaning quality and traceability.

[0078] Equipment structure integration points:

[0079] This embodiment constitutes a highly integrated, fully automated workstation. First, a flip-up drying assembly is integrated outside the washing tank, hinged to the outer surface of the top cover to form a sealed drying chamber, achieving integrated washing and drying. Second, to meet process traceability requirements, a rotary encoder is integrated on the guide rollers inside the top cover for real-time monitoring of the fabric's movement speed and length. Finally, its control system integrates a self-learning module, capable of automatically optimizing and generating washing program parameters based on historical washing effect feedback data, possessing intelligent evolution capabilities.

[0080] Workflow:

[0081] The workflow is fully automated washing, drying, and learning optimization. After the operator scans the fabric label and selects a program, the system executes automatically: the fabric is fed in by the conveyor system, positioned by the guide conveyor belt, and then cleaned in three stages according to a preset program (such as a high-frequency main and inert bubble mode to protect microfibers), during which the encoder monitors the operating parameters; after cleaning, the fabric is automatically transferred to the opened drying unit, the cavity is closed, and it is dried with a 60°C medium-temperature airflow circulation; after drying, if the quality inspection data is rated as "excellent", the self-learning module will associate and store the parameters and results for intelligent optimization recommendations for similar tasks in the future.

[0082] The advantages of this embodiment are: it achieves a "one-click" process from contaminated cloth to clean, dry cloth; through process monitoring and data traceability, it meets the stringent quality management requirements of the medical device or pharmaceutical industries; its self-learning function enables the equipment to continuously adapt to new materials and new contaminants, demonstrating a high degree of intelligence and significant long-term operational benefits.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
