[0002] Fabric printing and dyeing is the process of physically or chemically combining dyes with fibers, or using chemical methods to generate pigments on fibers, so that the entire textile has a certain color. It involves multiple links and aims to give the fabric rich colors and patterns while improving its performance and aesthetics.

[0003] The current printing and dyeing processes generally face the challenge of huge water consumption, especially in the washing, rinsing and dyeing processes. The demand for clean water is extremely large, which has caused the problem of excessive consumption of water resources. What is more serious is that the wastewater discharged in the washing step contains many unfixed dyes and chemical additives. These substances are not only difficult to effectively recycle and reuse, but also seriously pollute the environment, further exacerbating the tension of water resources.

[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Example

[0020] like Figures 1 to 5 Please refer to Figure 2 A water-saving, clean printing and dyeing processing device according to an embodiment of the present invention comprises a cleaning device 1; a feed inlet and a discharge inlet for fabrics are respectively provided on the left and right sides of the cleaning device 1; The cleaning device 1 is provided with four washing tanks 11 arranged in descending order of cleanliness. The four washing tanks 11 are used together to input high-cleanliness washing water into adjacent washing tanks 11 in sequence through three pumping components 12. Each washing tank 11 is rotatably connected with a plurality of transmission rollers 13 for transmitting fabrics, and the fabric transmission direction is opposite to the water delivery direction of the pumping assembly 12; a servo motor is externally connected to the outside of any transmission roller 13, and the servo motor is installed on the outer wall of the cleaning device 1, and the transmission roller 13 is intermittently driven by the servo motor to rotate, so that the fabric has enough time to soak in the washing tank 11; The lower end of the cleaning device 1 is connected to a wastewater treatment device 2 , and a multi-stage screen 5 for filtering fiber debris is slidably connected inside the wastewater treatment device 2 . A water purification component 6 is also arranged inside the wastewater treatment device 2 .

[0021] Specifically, the fabric is fed into the interior of the cleaning device 1 from the feed port, and the fabric first enters the washing tank 11 with the lowest cleanliness. After being soaked, the fabric is sequentially transmitted by multiple transmission rollers 13, so that the fabric passes through multiple washing tanks 11 for cleaning, until the fabric leaves the interior of the cleaning device 1 through the discharge port, and the pumping component 12 extracts the washing water in the current washing tank 11 into the washing tank 11 with the second-highest cleanliness. The fabric passes through four washing tanks 11 with cleanliness from low to high in sequence from the feed port in the cleaning device 1 for cleaning, and finally is thoroughly washed in the last washing tank 11 with the cleanest washing water. The wastewater in the washing tank 11 with the lowest cleanliness will automatically enter the interior of the wastewater treatment device 2, and the wastewater passes through the multi-stage screen 5 in sequence to remove internal fiber debris, and then is re-filtered by the water purification component 6, thereby realizing the purification, recycling and reuse of the water body.

[0022] Please refer to Figure 1 , Figure 2 , the pumping assembly 12 includes a first water pump 121 and a water pipe 122; A first water pump 121 is installed inside the washing tank 11, and the water outlet of each first water pump 121 is connected to a water pipe 122, and one end of each water pipe 122 away from the first water pump 121 is connected to the inside of the adjacent washing tank 11. It should be noted that the first water pump 121 is not installed in the washing tank 11 with the lowest cleanliness.

[0023] Specifically, the first water pump 121 will draw the washing water in the current washing tank 11 into the water pipe 122 until the washing water inside the water pipe 122 enters the washing tank 11 of inferior cleanliness, and utilizes the concentration difference to ensure that the washing water always maintains a high washing efficiency during the washing process. This washing method can always maintain the concentration difference between the lower concentration of washing water and the higher concentration of waste liquid in the slurry in each section, thereby giving full play to the washing effect of the washing water and achieving the purpose of increasing the concentration of the waste liquid. In this way, not only the use of fresh water can be reduced, but also the recycling rate of waste water can be improved.

[0024] Please refer to Figure 2 , Figure 3 The washing tank 11 with the highest cleanliness is also equipped with an ultrasonic washing device 14. The other three washing tanks 11 are each provided with two groups of brush plates 3 that move alternately left and right, and the brushing parts of the two groups of brush plates 3 are both attached to the upper and lower surfaces of the fabric.

[0025] Specifically, the ultrasonic generator power of the ultrasonic washing equipment 14 is 500W and the frequency is 40kHz, which is suitable for washing a variety of fabrics. The ultrasonic washing equipment 14 is used in the cleanest washing tank 11 to utilize the cavitation effect of ultrasound to enhance the washing effect and further remove stains on the surface of the fabric, thereby achieving the effect of enhanced cleaning. In each of the remaining washing tanks 11, two groups of brush plates 3 that move alternately left and right are used to enhance the washing effect and make the fabric cleaner. At the same time, brushing with the brush plate 3 can also destroy the stain structure on the surface of the fabric, making it easier to be removed by the detergent. Therefore, the brush plate 3 is combined with the countercurrent of the detergent to further improve the washing efficiency and reduce the washing time and water consumption.

[0026] Please refer to Figure 2 , Figure 3 , Figure 4Each bristle plate 3 is connected to a reciprocating screw 31 through a thread, and each reciprocating screw 31 is rotatably connected to the inside of the washing tank 11. Each bristle plate 3 is slidably connected to a sliding rod 32, and each sliding rod 32 is connected to the inside of the washing tank 11. One end of each reciprocating screw 31 close to the water outlet of the water pipe 122 is connected to a turbine 33, and the same side ends of two adjacent reciprocating screws 31 are connected to gears 34, and the outer walls of the two gears 34 are meshed with each other.

[0027] Specifically, the first water pump 121 draws washing water into the water pipe 122 and then sprays it out. When the washing water is sprayed out, it drives the turbine 33 to rotate, thereby causing the turbine 33 to drive the reciprocating screw 31 connected thereto to rotate in the washing tank 11. The reciprocating screw 31 rotates, thereby driving the brush plate 3 to move on the reciprocating screw 31 and the sliding rod 32. The reciprocating screw 31 rotates while driving the gear 34 to rotate, thereby causing the two gears 34 to rotate at the same time, thereby driving another reciprocating screw 31 under the fabric to rotate, thereby driving another group of brush plates 3 to move, causing the upper and lower brush plates 3 to move back and forth in an interlaced manner, thereby forming a two-way brushing effect on the fabric. This two-way force helps to more effectively remove stains and impurities on the fabric surface, especially those stains embedded deep in the fibers. When the two brush plates 3 move in opposite directions, they will form alternating pulling forces on the fabric. This alternating action helps to disperse the stress points of the fabric during the brushing process and reduce local excessive wear.

[0028] Please refer to Figure 2 A plurality of retractable scrapers 4 are equidistantly arranged inside the cleaning device 1, the bottom end of each scraper 4 is in contact with the fabric surface, and each scraper 4 cooperates with the transmission roller 13 to reduce the moisture on the fabric surface; a plurality of fixed plates 41 are equidistantly connected inside the cleaning device 1, and a plurality of first springs 42 are equidistantly connected inside each fixed plate 41, and the bottom ends of the plurality of first springs 42 are commonly connected to the top of the scraper 4.

[0029] Specifically, when the fabric is transported and moved on the upper transmission roller 13 inside the cleaning device 1, the scraper 4 is driven to move downward inside the fixed plate 41 under the action of the first spring 42, so that the bottom end of the scraper 4 is always in contact with the surface of the fabric of any thickness, thereby automatically scraping off part of the water stains on the surface of the fabric, so that the fabric can be more effectively in contact with new washing water when entering the next washing tank 11, which helps the effective ingredients in the washing water to penetrate into the fabric fibers faster, thereby accelerating the decomposition and removal of stains.

[0030] Please refer to Figure 1 , Figure 2A slag bin 21 and a wastewater purification bin 22 are provided inside the wastewater treatment device 2. The slag bin 21 is connected to the washing tank 11 with the lowest cleanliness. The multi-stage screen 5 is slidably connected inside the slag bin 21. The slag bin 21 and the wastewater purification bin 22 are connected, and a one-way valve 23 is provided at the connecting portion to prevent water in the wastewater purification bin 22 from flowing back. A guide plate 24 is connected to the inner wall of the slag bin 21, and the water purification component 6 is installed inside the wastewater purification bin 22.

[0031] Specifically, the wastewater in the washing tank 11 with the lowest cleanliness will automatically enter the slag bin 21 in the wastewater treatment device 2, and the fiber debris in the wastewater will be intercepted by the multi-stage screen 5 in the slag bin 21. The multi-stage screen 5 is provided with three filter screens with different mesh sizes distributed in sequence from top to bottom. The aperture sizes of the three filter screens decrease from top to bottom, and are used to intercept fiber debris of different sizes to further remove impurities in the wastewater. The filtered wastewater flows along the guide plate 24 through the one-way valve 23 into the wastewater purification bin 22, and then the wastewater is filtered for a second time through the water purification component 6.

[0032] Please refer to Figure 2 , Figure 5 Four guide columns 51 are connected inside the slag bin 21, and the multi-stage screen 5 is slidably connected to the four guide columns 51. The outer wall of each guide column 51 is connected to a second spring 52, and the other end of each second spring 52 is connected to the top of the multi-stage screen 5. The inner wall of the slag bin 21 is rotatably connected to a rotating rod 53, and a cam 54 is connected to the rotating rod 53. The outer wall of the cam 54 is attached to the bottom end of the multi-stage screen 5, and the rotating rod 53 is connected to the adjacent reciprocating screw rod 31 through a belt drive; pulleys are installed on the same side ends of the rotating rod 53 and the adjacent reciprocating screw rod 31, and a belt is wrapped around the outer walls of the two pulleys.

[0033] Specifically, the reciprocating screw rod 31 is driven by the belt to drive the rotating rod 53 to rotate inside the slag bin 21, so that the rotating rod 53 drives the cam 54 to rotate, so that the outer wall of the cam 54 continuously squeezes the multi-stage filter screen 5, and the multi-stage filter screen 5 slides on the four guide columns 51, thereby squeezing the second spring 52, and then realizing the reciprocating movement of the multi-stage filter screen 5 on the guide columns 51, thereby vibrating the multi-stage filter screen 5, preventing impurities in the wastewater from clogging the multi-stage filter screen 5, and thus accelerating the filtration and circulation of wastewater.

[0034] Please refer to Figure 2 , the water purification component 6 includes an activated carbon adsorption plate 61, a plate-and-frame reverse osmosis membrane 62, and a second water pump 63; An activated carbon adsorption plate 61 is installed on one side of the wastewater purification chamber 22 close to the one-way valve 23, a plate-and-frame reverse osmosis membrane 62 is installed on the other side of the activated carbon adsorption plate 61 away from the one-way valve 23, a second water pump 63 is installed on the side of the plate-and-frame reverse osmosis membrane 62 away from the activated carbon adsorption plate 61, and the water outlet of the second water pump 63 is connected to the washing tank 11 with the highest cleanliness through a pipe.

[0035] Specifically, after the impurities are removed, the wastewater enters the wastewater purification chamber 22, the organic matter is removed from the wastewater through the activated carbon adsorption plate 61, and then the wastewater is further purified through the plate and frame reverse osmosis membrane 62. The purified water is pumped into the washing tank 11 with the highest cleanliness through the second water pump 63, completing the collection and reuse of the wastewater.

[0036] A water-saving clean printing and dyeing process according to the above comprises the following steps: S1: placing the fabric to be printed and dyed into the washing tank 11 with the lowest cleanliness in the washing device 1, and ensuring that the fabric is completely immersed in the washing water; S2: Start the pumping assembly 12, so that the washing water in the washing tank 11 with the highest cleanliness level flows to the washing tank 11 with the lowest cleanliness level in turn, and wash the fabrics in turn. When the pumping assembly 12 is started, it will drive the multiple reciprocating screws 31 to drive the brush plate 3 to clean the fabric surface, thereby improving the cleaning effect of the washing water; S3: When the fabric enters the washing tank 11 with the highest cleanliness from the washing tank 11 with the lowest cleanliness, the ultrasonic washing device 14 is started to enhance the washing effect by using the cavitation effect of ultrasonic waves, thereby completing the washing work of the fabric; S4: During the washing process of the fabric, a certain amount of waste water will gradually accumulate in the washing tank 11 with the lowest cleanliness, and the waste water will automatically enter the slag bin 21, and the fiber impurities in the waste water will be filtered through the multi-stage screen 5. After the impurities are filtered, the waste water enters the waste water purification bin 22 through the one-way valve 23, and is purified by the activated carbon adsorption plate 61 and the plate and frame reverse osmosis membrane 62 in turn; S5: The purified wastewater is then returned to the washing tank 11 with the highest cleanliness through the second water pump 63, thereby realizing the recycling of water resources.

[0037] Working principle: The fabric is fed into the interior of the cleaning device 1 from the feed port, and the fabric first enters the washing tank 11 with the lowest cleanliness. After being soaked, the fabric is sequentially transmitted by multiple transmission rollers 13, so that the fabric passes through multiple washing tanks 11 for cleaning, until it leaves the interior of the cleaning device 1 through the discharge port, and the pumping component 12 will extract the washing water in the current washing tank 11 and enter the washing tank 11 with the second-highest cleanliness. The fabric passes through four washing tanks 11 with the cleanliness from the feed port in the cleaning device 1 in sequence for cleaning, and finally is thoroughly washed in the last washing tank 11 with the cleanest washing water. The first water pump 121 will extract the washing water in the current washing tank 11 into the water pipe 122, until the washing water in the water pipe 122 enters the washing tank 11 with the second-highest cleanliness. The concentration difference is used to make the washing water always maintain a high washing efficiency during the washing process. In the cleanest washing tank 11, the ultrasonic washing device 14 is used to enhance the washing effect by using the cavitation effect of the ultrasonic wave, and further remove the stains on the surface of the fabric, thereby achieving the effect of enhanced cleaning. The first water pump 121 draws washing water into the water pipe 122 and then sprays it out. When the washing water is sprayed out, it drives the turbine 33 to rotate, so that the turbine 33 drives the reciprocating screw 31 connected thereto to rotate in the washing tank 11. The reciprocating screw 31 rotates, and then drives the brush plate 3 to move on the reciprocating screw 31 and the sliding rod 32. The reciprocating screw 31 rotates while driving the gear 34 to rotate, so that the two gears 34 rotate at the same time, and then drives another reciprocating screw 31 under the fabric to rotate, thereby driving another set of brush plates 3 to move, so that the upper and lower brush plates 3 move back and forth alternately, forming a two-way brushing effect on the fabric. This two-way force helps to more effectively remove stains and impurities on the fabric surface, especially those stains embedded deep in the fibers. When the two brush plates 3 move in opposite directions, they will form alternating pulling forces on the fabric. This alternating action helps to disperse the stress points of the fabric during the brushing process and reduce local excessive wear. When the fabric is transported and moved on the driving roller 13 located at the top inside the cleaning device 1, the scraper 4 is driven to move downward inside the fixed plate 41 under the action of the first spring 42, so that the bottom end of the scraper 4 is always in contact with the surface of the fabric of any thickness, thereby automatically scraping off part of the water stains on the surface of the fabric, so that the fabric can be more effectively contacted with new washing water when entering the next washing tank 11, which helps the effective ingredients in the washing water to penetrate into the fabric fibers faster, thereby accelerating the decomposition and removal of stains; The wastewater in the washing tank 11 with the lowest cleanliness will automatically enter the slag bin 21 in the wastewater treatment device 2, and the fiber debris in the wastewater will be intercepted by the multi-stage screen 5 in the slag bin 21. The multi-stage screen 5 is provided with three filter screens with different mesh sizes, which are distributed in sequence from top to bottom. The aperture sizes of the three filter screens decrease from top to bottom, and are used to intercept fiber debris of different sizes, further removing impurities in the wastewater. The filtered wastewater flows along the guide plate 24 through the one-way valve 23 into the wastewater purification bin 22, and then the wastewater is filtered for a second time by the water purification component 6. The reciprocating screw rod 31 is driven by the belt to drive the rotating rod 53 to rotate inside the slag bin 21, so that the rotating rod 53 drives the cam 54 to rotate, so that the outer wall of the cam 54 continuously squeezes the multi-stage filter screen 5, so that the multi-stage filter screen 5 slides on the four guide pillars 51, thereby squeezing the second spring 52, and then realizing the reciprocating movement of the multi-stage filter screen 5 on the guide pillars 51, thereby vibrating the multi-stage filter screen 5, preventing impurities in the wastewater from clogging the multi-stage filter screen 5, and thus accelerating the filtration and circulation of the wastewater; After the impurities are removed, the wastewater enters the wastewater purification chamber 22, and the organic matter is removed from the wastewater by the activated carbon adsorption plate 61, and then the wastewater is further purified by the plate and frame reverse osmosis membrane 62. The purified water is pumped into the washing tank 11 with the highest cleanliness by the second water pump 63, completing the collection and reuse of the wastewater.
