Description

Technical Field

[0001] This invention relates to a cleaning device, specifically a water washing device for animal hair fibers used in laboratory testing. Background Technology

[0002] The structure of wool fibers is a very complex protein structure. The cortex is usually composed of orthocortical and paracortical cells, which have different structures and different physical and chemical properties. Orthocortical cells are relatively small and uniform, with clear boundaries, and easily adsorb basic pigments. Paracortical cells are larger, irregularly shaped, and more easily adsorb acidic pigments. Washing equipment, as the name suggests, is equipment that uses water to clean. Similar in meaning to washing equipment, washing machinery, and water washing machinery, washing equipment is used to wash cotton, wool, synthetic fibers, silk, and other fabrics. It can be used in garment factories to wash denim and silk garments. Washing equipment is suitable for hotels, restaurants, hospitals, schools, factories, and other fields, meeting the requirements for large-capacity laundry.

[0003] When testing animal plush fibers in the laboratory, the fibers need to be cleaned to remove dust and other impurities from the surface. Therefore, a water washing device is proposed to suit laboratory use. Summary of the Invention

A central tube 25 adapted to it is provided inside the through pipe 30. The central tube 25 vertically passes through the lower shell 31 and upper shell 32 of the barrel body 29 through the through pipe 30 and is statically and tightly fixed to the through pipe 30. The upper end of the central tube 25 is inserted into the washing chamber 28 and its inner wall is fixedly connected with a heat insulation coating layer. Ultrasonic transducers 26 are fixedly installed at equal intervals in the circumferential and vertical directions on the heat insulation coating layer. The ultrasonic transducers 26 adopt existing cleaning-specific ultrasonic transducers and are manufactured by Honda Japan. The device, manufactured and commercially available by Electronics Co., Ltd. with model number HEC-45402, or manufactured and commercially available by Yiwei Ultrasonic Technology (Shenzhen) Co., Ltd. with model number CD-38-5600, has an aerogel insulation sleeve 27 fixedly connected to the inner side of the lower end of the central tube 25. The upper end face of the aerogel insulation sleeve 27 is flush with the top surface of the upper shell 32 of the barrel 29, and the top end of the central tube 25 extends out of the barrel 29.The lower wall shell 31 has through holes 35 evenly distributed around the central tube 25 in the circumferential direction at the inner annular portion near the lower central perforation 12. A matching sealing shell 36 is provided above the through holes 35, and the sealing shell 36 is fixedly connected to the lower wall shell 31. A magnetron 20 is installed inside the sealing shell 36. The magnetron 20 is manufactured and commercially available from Panasonic Corporation of Japan, model MG12W-M31. The microwaves emitted by the microwave transmitter inside the recessed mounting portion 21 can penetrate unimpeded through the sealing shell 36 into the heating water jacket. The lower wall shell 31 has eccentric perforations 18 evenly distributed around the central tube 25 in the circumferential direction at the outer annular portion away from the lower central perforation 12. A drive shaft 8 is installed inside the eccentric perforation 18. The drive shaft 8 passes through the eccentric perforation 18, penetrates the lower wall shell 31, and dynamically seals with the eccentric perforation 18 by rotating. A corresponding L-shaped hanger 10 is provided on the lower outer side of the eccentric perforation 18. A hanger 10 is fixedly connected to the bottom surface of the lower shell 31. A third rotary motor 9 is fixedly installed on the L-shaped hanger 10. One end of the drive shaft 8 is inserted into the heating chamber 5 and fixedly connected to a third axial propeller 7. The other end of the drive shaft 8 is fixedly connected to the output shaft of the third rotary motor 9 via a coupling. A platform 11 is fixedly installed on the bottom surface of the barrel 29. A matching support plate 34 is fixedly connected to the inner bottom of the platform 11. A first rotary motor 14 corresponding to the central tube 25 is fixedly installed in the middle of the top surface of the support plate 34. The output shaft of the first rotary motor 14 is vertically upward and fixedly connected to a first axial propeller 13 via a coupling.

A second rotary motor 16 is fixedly installed on the top surface of the bracket 15. The output shaft of the second rotary motor 16 is vertically upward and fixedly connected to a second axial propeller 17 via a coupling.

[0022] The barrel body 29 is entirely made of metal.

[0023] The heating chamber 5 is interconnected through the inlet hole 19, the outer cylindrical guide channel 4, the outlet hole 33 and the inner cylindrical guide channel 3.

[0024] The ultrasonic transmitting probes on the top of the ultrasonic transducer 26 are all arranged radially along the central tube 25 and point towards the inner wall shell 37 of the barrel 29.

[0025] The bottom wall of the sealing shell 36 faces upward toward the upper shell 32, and the interior of the sealing shell 36 is exposed from the outer surface of the lower shell 31. The sealing shell 36 as a whole or its bottom wall is made of an insulator that can transmit microwaves.

[0026] The front end face of the third rotary motor 9, which has a power output shaft, is provided with a gap between itself and the lower wall shell 31 so that they do not contact each other. This is to prevent the heat of the high-temperature distilled water being heated in the heating chamber 5 from being conducted to the third rotary motor 9 through the lower wall shell 31.

[0027] The first axial propeller 13 is suspended near the lower end of the central tube 25 in a non-contact manner, and the second axial propeller 17 is suspended near the back of the magnetron 20 in a non-contact manner.

[0028] The working principle of this invention is:

[0029] Before its first application, ensure that the water jacket of the container 29 is filled with distilled water. Therefore, first place the invention upright in a plush fiber laboratory. Under essentially dust-free conditions and room temperature, first manually unscrew the sealing cap 22 that originally fixed and sealed the distilled water inlet / outlet 24, and remove the sealing cap 22. Then, pour the prepared distilled water into the water jacket through the distilled water inlet / outlet 24 until the water level in the water jacket rises to the distilled water inlet / outlet 24 and covers the uppermost edge of the distilled water inlet / outlet 24 or slightly overflows from the distilled water inlet / outlet 24. Ensure that all air in the water jacket is discharged from the container 29 through the distilled water inlet / outlet 24. Then, manually screw the sealing cap 22 to fix and seal the distilled water inlet / outlet 24. Since the distilled water can be isolated in the water jacket for a long time and will not be contaminated by the outside, thereafter, under normal circumstances, it is not necessary to open the distilled water inlet / outlet 24.

[0030] When starting up, first pour sufficient tap water (preferably high-efficiency filtered tap water with low hardness to avoid significant sediment buildup on the inner wall of the washing chamber 28 after heating) into the washing chamber 28 through the open spout 6. However, the water level in the washing chamber 28 should be lower than the top of the tub 29 to prevent water from overflowing from the upper end of the central pipe 25 and wetting the ultrasonic transducer 26. This also further prevents water from dripping down the central pipe 25 onto the first rotary motor 14, preventing damage to the ultrasonic transducer 26 and the first rotary motor 14 from water immersion, ensuring electrical safety. Then add a cashmere and wool detergent (yuan) matching the weight of the tap water in the washing chamber 28. Adding ingredients such as sodium sulfate (or similar powders), tap water and detergent are initially stirred manually with a wooden stirring rod to form a washing solution. Then, an appropriate amount of wool fiber samples collected from various wool-producing sheep and alpacas (such as Merino sheep) are added to the washing chamber 28. The total weight of the wool fiber samples added to the purified water matches the weight of the washing solution. Because the central tube 25 is statically and seamlessly fixed to the through-tube 30 by passing through it, the washing solution in the washing chamber 28 will not flow down through the through-tube 30 to the bottom of the tank 29 and wet the corresponding electrical components such as the rotary motor and magnetron 20. The magnetron 20 is then activated to emit microwaves at a frequency of 2450MHz (the electromagnetic wave frequency of a microwave oven) into the water jacket, starting the first... The second rotary motor 16 drives the second axial propeller 17 to rotate, causing air to flow towards or away from the magnetron 20, thus providing timely air cooling for the magnetron 20 which generates heat during operation. This ensures reliable and stable operation of the magnetron 20 and extends its service life. Since the shell of the barrel 29 is made of microwave-reflective metal, the sample fibers are washed and heated without damage. Microwaves reflect back and forth along different paths within the heating chamber 5 and the cylindrical heat transfer channel according to the ultra-high frequency electromagnetic wave reflection law, subsequently filling the water jacket comprehensively. The microwave heating effect rapidly raises the temperature of the distilled water. After heating, the distilled water acts as a heat transfer medium, continuously heated through the inner wall shell 37 of the washing chamber 28. The washing solution inside chamber 28, after being dissolved in tap water, performs a non-destructive chemical cleaning of the sample wool and cashmere. The heated washing solution simultaneously heats the sample wool fibers, further enhancing the washing effectiveness of the detergent. The groove-shaped sealing shell 36 is made of rigid engineering plastic. Microwaves emitted from the microwave transmitter, whose magnetron is built into the recessed mounting part 21, can penetrate unimpeded through the sealing shell 36 into the heating water jacket. The metal shell of the barrel 29 prevents electromagnetic waves from penetrating into the washing chamber 28 and outside the barrel 29, ensuring safe use and shielding the sample wool fibers, which are composed of organic proteins, from harmful physical effects of microwaves. Simultaneously, the ultrasonic transducer 26 is activated.The ultrasonic transducer 26 emits ultrasonic waves at a frequency of 20-40kHz radially through the peripheral wall of the central tube 25 towards the washing liquid and sample wool / cashmere in the washing chamber 28 in a static, fixed state. This activates the first rotary motor 14, which drives the first axial propeller 13 to rotate, causing cooler air to flow towards the lower end of the central tube 25. The air enters the central tube 25 through the lower end and flows upwards, exiting from the upper end of the central tube 25. This air flow effectively cools the ultrasonic transducer 26, which generates heat during operation. The air, heated by the absorption of heat from the ultrasonic transducer 26, flows out from the upper end of the central tube 25, thus providing timely cooling for the ultrasonic transducer. The transducer 26 operates reliably and stably. The heat-insulating coating layer, fixedly applied to the tail end face of the ultrasonic transducer 26 or evenly distributed and fixedly applied to the inner circumferential wall of the central tube 25, effectively prevents the heat from the high-temperature washing liquid or water in the washing chamber 28 from being conducted to the ultrasonic transducer 26 through the circumferential wall of the central tube 25. This avoids the ultrasonic transducer 26 being heated by the washing liquid or water, extending its service life. Furthermore, the cooler air discharged to the central tube 25 by the first axial propeller 13 enters the central tube 25 to cool the ultrasonic transducer 26. To prevent the cooler air from being affected by the second axial propeller 17 below the barrel 29 when flowing through the section of the central tube 25 below the heating chamber 5, further measures are taken. The hotter air, driven by the magnetron 20, is heated. To prevent the cooler air from being heated by the distilled water in the heating chamber 5 as it flows upward through the central tube 25 surrounded by the through tube 30, an aerogel insulation sleeve 27 is fixedly fitted inside the section of the central tube 25 that passes through and is located below the heating chamber 5. The aerogel insulation sleeve 27 blocks the high heat of the microwave-heated distilled water from being conducted through the through tube 30 and the central tube 25 to the air flowing upward through the aerogel insulation sleeve 27 in the central tube 25. This ensures that the air entering from the lower end of the central tube 25 is not heated by the distilled water, thus minimizing the temperature rise of the air flowing through the central tube 25 and allowing the air to be heated as much as possible. Multiple locations absorb heat from the ultrasonic transducer 26, improving the cooling efficiency of the ambient air flowing upward through the central tube 25. The ultrasonic waves cavitate, radiate pressure, and generate acoustic flow in the washing liquid, physically ultrasonically cleaning the wool and cashmere samples through these processes. The third rotary motor 9 is activated, driving the third axial propeller to rotate via the drive shaft 8. Because the drive shaft 8 and the eccentric perforation 18 are dynamically sealed, the water in the heating chamber 5 will not leak through the eccentric perforation 18 to the bottom of the barrel 29 and wet the third rotary motor 9. When the third axial propeller 7 rotates, it can forcefully drive the heated water located between the sealing shell 36 and the inlet hole 19 in the heating chamber 5 towards the inlet hole 19.Driven by the third axial propeller 7, the heated water can only circulate sequentially through the inlet hole 19, the outer cylindrical guide channel 4, the outlet hole 33, and the inner cylindrical guide channel 3 into the heating chamber 5. This circulation within the water jacket not only facilitates the rapid and seamless diffusion of the microwave-heated distilled water to all parts of the heating water jacket, but also allows the heated water, when forced to flow upwards through the outer cylindrical guide channel 4, to exchange heat with the cooler air outside the barrel 29 via the outer peripheral wall shell 38. This dissipates heat from the excessively hot distilled water flowing through the outer cylindrical guide channel 4, resulting in a significant temperature reduction. Consequently, the temperature of the water flowing through the inner cylindrical guide channel 3 and ultimately into the heating chamber 5 is also reduced. This will correspondingly lower the temperature, maintaining the temperature of the distilled water in the heating water jacket between 70℃ and 75℃, thus appropriately cooling the washing solution in the washing chamber 28 and limiting its temperature to between 65℃ and 70℃. This prevents the washing solution from becoming too hot. If the sample wool fibers are heated in an excessively high-temperature environment, subsequent quality inspection results after washing and drying will be distorted, rendering the inspection results meaningless. Therefore, lowering the temperature of the washing solution to a temperature that the sample wool fibers can tolerate ensures that the quality of the sample wool fibers to be tested is not significantly affected. The chemical non-destructive cleaning of the detergent and the microwave heating and ultrasonic cavitation cleaning can effectively remove various tiny impurity particles originally present in the sample wool fibers (which are inherently...). Some oil particles and adhering dust particles detach from the sample fibers, causing most of them to remain suspended in the washing liquid or a very small portion to settle on the bottom surface of the washing chamber 28. This results in the washing liquid collecting tiny impurities and forming wastewater. After heating for a sufficiently long time, the magnetron 20 and ultrasonic transducer 26 are first turned off, while all rotating motors are kept running for an appropriate period to allow the distilled water, magnetron 20, and ultrasonic transducer 26 to cool down significantly. Then, all rotating motors are turned off again. Once the washing liquid has cooled down significantly, the sample fibers are removed from the washing liquid and placed in a container. Then, one end of the inlet pipe connected to the inlet of the small wastewater pump is placed at the bottom of the washing chamber 28, and the small wastewater pump is turned on to pump the wastewater from the washing chamber 28. Wastewater from washing the sample fibers is discharged into the sewer through an inlet pipe, a small wastewater pump, and an outlet pipe connected to the pump's outlet. Any remaining impurities or sediment on the bottom of the washing chamber 28 can be wiped away with a damp sponge or other cleaning cloth. Next, add an appropriate amount of clean water to the washing chamber 28, and then place the sample fibers, which have just been washed with detergent and microwave ultrasonic heating, back into the chamber, but without adding detergent. The remaining operations follow the corresponding sections of the above-described procedure. The sample fibers, initially washed with detergent, undergo a second microwave ultrasonic heating wash. After removing the sample fibers from the washing chamber 28 and completing the necessary operations, they are drained / spin-dried and then dried before proceeding with subsequent quality inspection procedures.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
