Description

Technical Field

[0001] The invention relates to an open-width washing machine, in particular to a high-efficiency continuous open-width washing machine. Background Art

[0002] It is known that in the printing and dyeing industry, after the textiles are dyed, they need to be cleaned by a washing machine to remove impurities such as dye residues, broken fibers, oil stains, etc., and to make the textiles smooth and soft. The washing machine that processes the cloth is called an open-width washing machine.

[0003] Traditional open-width washing machines have washing devices inside, collectively called washing tanks, which use spraying cleaning liquid and immersion washing to clean cloth. Since they can only clean surface impurities, the washing efficiency is low and generally more than 4 sets of washing tanks are required for repetitive cleaning. This wastes water resources, consumes high energy, occupies a large area, and has a long working time. Summary of the invention

[0004] The purpose of the present invention is to provide a high-efficiency continuous open-width washing machine, which adopts special washing steps to improve washing efficiency and significantly reduce the overall energy consumption of the product, thereby improving production efficiency and environmental protection indicators.

[0005] In order to achieve the above technical objectives, the high-efficiency continuous open-width washing machine of the present invention includes a frame, a cloth feeding device, a centering device, a plurality of washing pools, a heating pre-shrinking area, a cloth outlet rack and other units. The washing pool includes a cloth lifting shaft, a cloth guide shaft and a spray device with a nozzle, and stores washing liquid. The cloth lifting shaft is located above the washing pool, the cloth guide shaft is located inside the washing pool, and the nozzle group of the spray device is located behind the cloth lifting shaft and faces the cloth.

[0006] The aforementioned spray device also includes a microbubble-rich water flow generator, which generates a microbubble-rich water flow that is sprayed toward the fabric through a nozzle. After the microbubble-rich water flow enters the interior of the fabric, the microbubbles expand and push the impurities in the fabric to the surface of the fabric, thereby quickly cleaning the deep impurities in the fabric. After the microbubbles reach the surface of the fabric, they eventually explode on the surface of the fabric, generating ultrasonic shocks that push the impurities away from the fabric, thereby achieving the purpose of efficient cleaning.

[0007] The micro-bubble-rich water flow generator is cylindrical in shape, with an air inlet and a jet water outlet at the bottom, air and water are provided to the air inlet and the jet water outlet by an air pump and a water pump, the air inlet is connected to a porous bubbler through a pipe to generate bubbles; the direction of the jet water outlet is horizontally tangent to the inner wall of the micro-bubble-rich water flow generator, and a spiral upward water flow is generated after entering the water, a cutting net is provided above the micro-bubble-rich water flow generator, and bubbles are cut into tiny bubbles, the micro-bubble-rich water flow generator also includes a heating tube inside, and a micro-bubble-rich water outlet is provided above.

[0008] When the micro-bubble-rich water flow generator is working, the spirally rising water flow is mixed with bubbles, and the spiral water flow passes through the cutting net and is cut into smaller bubbles, thereby generating a micro-bubble-rich water flow.

[0009] As a better design, the cutting net is installed vertically in the micro-bubble-rich water flow generator to improve the cutting efficiency. In the center of the micro-bubble-rich water flow generator is a closed long heating tube to avoid rupture or fusion caused by rapid heating of the micro-bubble-rich water flow, thereby improving the bubbling efficiency.

[0010] The micro-bubble-rich water flow generated by the micro-bubble-rich water flow generator of the present invention has a bubble diameter of less than 100 microns and a gas-to-water ratio of more than 0.5:1.

[0011] In order to further save water resources, the heating pre-shrinking zone of the present invention also includes a set of vacuum moisture absorption and cooling devices; the vacuum moisture absorption and cooling device includes a vacuum moisture absorption and cooling pipe and a connected vacuum moisture absorber; the vacuum moisture absorption and cooling pipe has moisture absorption holes on the side facing the fabric, and movable sealing sleeves at both ends. When the hot fabric with water vapor passes through the moisture absorption holes of the vacuum moisture absorption and cooling pipe, the high-temperature water vapor is absorbed, thereby achieving the purpose of rapid cooling and drying.

[0012] As an optimization, the vacuum dehumidification and cooling device, the water absorbed by the vacuum dehumidifier, returns to the last washing pool. This step can recycle clean water resources and save water resources and heating resources.

[0013] Since the washing efficiency of the present invention is much higher than that of the traditional washing machine, only three groups of washing pools are needed to achieve the cleaning effect of 4-5 groups of washing pools of the traditional product. The order of the three groups of washing pools is the heavy dirt washing pool, the light dirt washing pool and the cleaning pool.

[0014] Optimized, each washing pool adopts an independent micro-bubble-rich water flow generator, and draws water from the subsequent washing pool, so that water resources are fully recycled and the energy-saving and water-saving environmental protection indicators of the product are improved.

[0015] Optimized, the aforementioned centering device is an infrared centering device, which can improve the edge recognition rate of solid color, patterned color and new color evolution products, enhance the centering effect, prevent edge overlap and reduce manual intervention.

[0016] The advantages and benefits of the present invention are: using the micro-bubble-rich water flow generated by the micro-bubble-rich water flow generator to wash the cloth, utilizing the expansion and bursting characteristics of the micro-bubbles to efficiently remove impurities deep in the cloth, thereby improving the washing efficiency and efficiently saving energy and water.

[0017] The present invention also adopts a vacuum moisture absorption and cooling tube, which can quickly cool and dry the cloth and recycle high-temperature water; improve the efficiency of water resource utilization and reduce heat energy consumption; and adopt an infrared centering device to make the centering of the cloth more accurate.

[0027] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0028] It is used to more clearly illustrate the technical solution of the present invention, but it cannot be used to limit the protection scope of the present invention.

[0029] like Figure 1The first embodiment of the high-efficiency continuous open-width washing machine of the present invention is shown, and there are infrared centering devices 2 and cloth feeding devices 3 at the entrance of the frame, and three washing pools, namely, a heavy-dirty washing pool 4, a light-dirty washing pool 5 and a cleaning pool 6, in the middle of the frame, and a heating pre-shrinking area 7 and a cloth outlet rack 9 at the end of the frame, and the cloth 1 passes through the above units in sequence. Each washing pool has a cloth lifting shaft 14, a plurality of cloth guide shafts 13 and a spray device with a nozzle 11, and the washing liquid is stored inside. The cloth lifting shaft 14 is located above the washing pool, and its function is to raise the height of the cloth 1 through the partition wall between each unit. The cloth guide shaft 13 is located inside the washing pool, and its function is to immerse the cloth 1 into the deep of the washing pool and into the stored washing liquid for soaking and washing. The nozzle 11 of the spray device is located behind the cloth lifting shaft, higher than the washing liquid level, and facing the cloth plane. There is also a drain 20 at the bottom of each washing pool, and when the liquid level is too high, the excess washing liquid is discharged.

[0030] In this embodiment, a micro-bubble-rich water flow generator 12 is also included. The micro-bubble-rich water outlet 11201 is connected to the nozzle 11 through a pipeline, and the micro-bubble-rich water flow generated by the micro-bubble-rich water flow generator 12 is sprayed toward the fabric 1 through the nozzle 11.

[0031] The heating pre-shrinking zone 7 of the present embodiment also includes a set of vacuum moisture absorption and cooling devices; the vacuum moisture absorption and cooling devices include a vacuum moisture absorption and cooling pipe 8 and a connected vacuum desiccant 10, which can quickly absorb the high-temperature water vapor of the cloth, thereby achieving the purpose of rapid cooling and drying. Since the moisture carried by the cloth at this stage is already quite clean, the present embodiment returns the moisture absorbed by the vacuum desiccant 10 to the cleaning pool 6. This design can recycle clean water and save water resources and heating resources.

[0032] like Figure 2 As shown, the micro-bubble-rich water flow generator 12 of the present invention is cylindrical in shape, with an air inlet 1207 and a jet water outlet 1208 at the bottom, and air and liquid are provided to the air inlet 1207 and the jet water outlet 1208 by an air pump 1205 and a water pump 1206. The air inlet 1207 is connected to a porous bubbler 1203 through a pipe to generate bubbles; the water outlet direction of the jet water outlet 1208 is horizontally tangent to the inner wall of the cylinder of the micro-bubble-rich water flow generator 12, and a spiral upward water flow is generated after the liquid enters. A multi-layer cutting net 1202 is provided above the inside of the micro-bubble-rich water flow generator 12, and bubbles mixed in the liquid are cut into tiny bubbles when passing through. The micro-bubble-rich water flow generator 12 also includes a heating tube 1204, and a micro-bubble-rich water outlet 1201 is provided above. When the micro-bubble-rich water flow generator 12 is working, the spirally rising liquid water flow is mixed with bubbles and spirally passes through the cutting net to be cut into smaller bubbles, thereby generating a micro-bubble-rich water flow.

[0033] like Figure 3As shown in FIG. 1 , an optimized structure of the micro-bubble-rich water flow generator 12 is shown, in which the cutting net 1202 is directly installed in the micro-bubble-rich water flow generator 12, and the center is a closed long strip heating tube 1204. The vertical surface cutting net 1202 increases the number of times the bubbles are cut and improves the bubble formation efficiency, while the long heating tube 1204 gradually increases the liquid temperature, and the generated bubbles also gradually expand with the water temperature, and the surface tension is stable; it will not Figure 2 In the structure, due to the concentrated heating at the bottom, the temperature difference is too large, the bubbles will break or merge, reducing the bubbling efficiency.

[0034] like Figure 4 As shown, in the micro-bubble-rich water flow generator 12, the center is a closed heating tube 1204, and the cutting net 1202 surrounds the heating tube 1204 and is arranged radially. Therefore, each time the liquid water flow goes around a circle, it is cut by the cutting net 1202 for many times, and the bubbling efficiency is higher. In this design, the angle of the water flow injected through the jet nozzle can be tilted toward the water outlet direction to achieve higher water outlet efficiency and improve the overall output flow of the micro-bubble-rich water flow generator 12 device.

[0035] like Figure 2-4 The micro-bubble-rich water flow generated by the micro-bubble-rich water flow generator 12 shown has bubbles with a diameter between 30 and 50 microns, and an input gas to liquid volume ratio of 1:1.

[0036] Figure 2-4 The structure of the microbubble-rich water flow generator 12 shown cannot be regarded as a limitation on the microbubble-rich water flow generator used in the present invention. Any device that can generate a microbubble-rich water flow that meets the required indicators of the present invention can be applied to the present invention.

[0037] like Figure 5 As shown in the figure, the principle diagram of the present invention using a water flow rich in microbubbles to wash printing and dyeing impurities is enlarged for a clear composition. In the figure, the triangle represents printing and dyeing impurities, and the circle represents microbubbles. As shown by the arrow, it is the running direction of the cloth 1. The inside of the cloth undergoes three stages of changes: infiltration, expansion, and bursting. The first stage is the infiltration stage. The water flow rich in microbubbles is sprayed through the nozzle 11 and penetrates into the inside of the cloth under the water flow pressure; the second stage is the expansion stage. After leaving the spraying area, the microbubbles expand and push the impurities in the cloth to the surface of the cloth, which can quickly clean the deep impurities in the cloth; in the subsequent bursting stage, after the microbubbles reach the surface of the cloth, they finally explode on the surface of the cloth, generating ultrasonic shock, pushing the impurities away from the surface of the cloth, and avoiding the retention of printing and dyeing impurities on the surface of the cloth due to their greasy and sticky characteristics, so as to achieve the purpose of efficiently cleaning the printing and dyeing impurities.

[0038] In this embodiment, only three groups of washing pools are needed to achieve the cleaning effect of 4-5 groups of washing pools of traditional products. Therefore, it has the advantages of high efficiency, energy saving, small footprint, etc., and also saves the amount of washing detergent, thereby reducing washing costs and sewage discharge.

[0039] like Figure 1 In the first embodiment of the present invention, only one group of micro-bubble-rich water flow generators 12 is used to provide micro-bubble-rich water flow to the nozzles of the three washing pools at the same time. However, in actual production, the conditions of the processed fabrics vary greatly, and it may be necessary to add detergent to the micro-bubble water flow in stages. Figure 1 The embodiment shown is subject to certain limitations in practical use and can only provide superior washing performance for a relatively single type of cloth.

[0040] like Figure 6 The second embodiment of the high-efficiency continuous open-width washing machine of the present invention is shown, in which each washing pool is equipped with a set of micro-bubble-rich water flow generators. In order to make full use of water resources, each set of micro-bubble-rich water flow generators draws water from the washing pool at the rear. The figure simplifies the composition and hides parts such as cloth shafts.

[0041] Specifically, the micro-bubble-rich water flow generator 12 matched with the heavy-dirty washing tank 4 draws water from the light-dirty washing tank 5 through a pipeline, and a detergent mixing port 1200 is provided on the pipeline; the micro-bubble-rich water flow generator 15 matched with the light-dirty washing tank 5 draws water from the cleaning tank 6 through a pipeline, and a detergent mixing port 1500 is provided on the pipeline; the micro-bubble-rich water flow generator 16 matched with the cleaning tank 6 draws water from the return water of the vacuum dehumidifier 10 through a pipeline, and a water adding port 1600 is provided on the pipeline, so that clean water can be added to replenish the water level of the whole set of machinery at any time.

[0042] The second embodiment of the present invention, through the vacuum dehumidification and cooling device composed of the vacuum dehumidification and cooling tube 8 and the vacuum dehumidifier 10, not only quickly cools the cloth, but also recovers the clean high-temperature water vapor contained in the cloth, and uses it as the source of the micro-bubble-rich water flow sprayed by the cleaning tank 6. The cleaner cleaning water in the cleaning tank 6 is filtered and used as the source of the micro-bubble-rich water flow sprayed by the light-contaminated washing tank 5. Finally, the cleaning water with a lower degree of pollution in the light-contaminated washing tank 5 is filtered and used as the source of the micro-bubble-rich water flow sprayed by the heavy-contaminated washing tank 4. In this way, the step-by-step reuse of water resources is realized, which saves more than 30% water than the traditional flat-width washing machine, and saves the heat energy for heating the washing water.

[0043] Figure 6 All water intake areas are filtered through filters to remove impurities in the water. For occasions with higher requirements, independent filtration systems can be added as needed. Since various filtration systems are mature products in the industry, they will not be described in detail here.

[0044] like Figure 7-8 As shown, the structure of the vacuum moisture absorption and cooling tube 8 has moisture absorption holes 801 on the side facing the contact with the cloth, and movable sealing sleeves are provided at both ends, namely a left sealing sleeve 802 and a right sealing sleeve 803. The function of the sealing sleeve is to move with the width and position of the cloth to seal the moisture absorption holes 801 outside the contact area between the vacuum moisture absorption and cooling tube 8 and the cloth, so as to prevent air leakage and make the moisture absorption capacity stronger.

[0045] The vacuum moisture absorption and cooling tube 8 is in direct contact and friction with the fabric, so it is necessary to use a material with a small friction coefficient. The moisture absorption hole 801 needs to be polished as smooth as possible and adopt different shapes according to different fabrics. Specifically, for thicker fabrics, long gaps are preferred to improve moisture absorption efficiency, while for thinner fabrics, Figure 7 The staggered intermittent gap holes shown in the figure are used to improve the bearing capacity of the fabric and prevent thin fabrics from wrinkling due to suction. Various types of gaps can be adjusted and replaced according to actual production needs.

[0046] The effective benefit of the present invention is that, taking Example 2 as an example compared with a traditional 4-tank washing machine, it can save about one-fifth of the equipment volume, save 30% to 50% of the detergent and cleaning agent usage, save about 20% to 35% of water, save 10% of heating energy, and the pollution index of the discharged wastewater is reduced by more than one-third.

[0047] The above is only a preferred embodiment of the present invention. In the actual deployment process of the present invention, due to different production process requirements, it is not possible to operate completely according to the above embodiments. Therefore, the embodiments of the present invention should not be understood as limiting the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical principles of the present invention, several improvements and adjustments can be made, and these improvements and adjustments should also be regarded as within the effective protection scope of the present invention.
