Referring to fig. 1, fig. 1 shows a module schematic diagram of an intelligent water saving system in an embodiment of the present invention, and the intelligent water saving system provided in an embodiment of the present invention includes: a first wash water tank 100, a water flow line 200, and a control module 300. Wherein the first water-washing tank 100 stores water for washing cloth in the spinning process; the water flow pipeline 200 can facilitate the water in the first water tank to flow out and supply water to the first water washing tank 100, and the water flow pipeline 200 is provided with an absorbance detection sensor 216 which can detect the color depth of the water flowing through the first water washing tank 100 and feed back the color depth to the control module 300; the control module 300 can determine whether the water flow line 200 is supplementing water into the first wash water tank 100 based on the absorbance value detected by the absorbance detection sensor 216. The absorbance refers to the logarithm of the ratio of the incident light intensity before the light passes through the solution or the substance to the transmitted light intensity after the light passes through the solution or the substance, which is based on 10, and can reflect the color depth of the water body. The greater the absorbance value, the greater the color depth of the water body. Of course, when different sensors or calculation formulas are adopted, the finally defined absorbance value can also be in an inverse correlation relationship with the color depth. Because this embodiment is based on the color depth degree index in first wash water tank 100 and judges whether need to add water in first wash water tank 100, therefore it compares current adoption regular water supply scheme, can play the purpose of using water wisely, reduction water cost.

Specifically, the first water washing tank 100 comprises an a1 water inlet 110, an a2 water outlet 120, wherein a heating module 130 is arranged in the first water washing tank 100; it should be noted that the first water washing tank 100 is pre-stored with water, for example, before use, water is introduced into the inlet 110 of the a 1; in addition, in the fabric washing process, the temperature of the water in the first water washing tank 100 needs to be maintained constant, and for this purpose, a heating module 130 needs to be arranged in the first water washing tank 100, and the heating module 130 may be a constant temperature steam pipe or a constant temperature heating module including a temperature sensor and a heating pipe.

The water flow pipeline 200 comprises a return pipeline 210, wherein the return pipeline 210 comprises a first pipeline 211 and a second pipeline 212, a heat exchanger 213 is arranged between the first pipeline 211 and the second pipeline 212, the heat exchanger 213 can be a plate heat exchanger 213, and the heat exchanger 213 comprises a first water inlet 2131 and a first water outlet 2132 which are communicated with each other, and a second water inlet 2133 and a second water outlet 2134 which are communicated with each other; one end of the first pipeline 211 is communicated with the a2 water outlet 120 of the first water washing tank 100, the other end of the first pipeline 211 is communicated with the first water inlet 2131 of the heat exchanger 213, the second water outlet 2134 is communicated with the external space outside the intelligent water saving system, for example, the second water outlet 2134 can be communicated with the wastewater recovery tank, the first pipeline 211 is provided with a first electromagnetic control valve 214, a branch pipeline 215 is arranged on the first pipeline 211 and is close to the a2 water outlet 120 of the first water washing tank 100 and between the first electromagnetic control valve 214, wherein the branch pipeline 215 is provided with an absorbance detection sensor 216, that is, one end of the branch pipeline 215 is communicated with the first pipeline 211, and the other end of the branch pipeline 215 can be directly communicated with the wastewater recovery tank or flow into the first water inlet 2131 of the heat exchanger 213 through a branch joint. It should be noted that the first solenoid control valve 214 may be a flow meter proportional valve of the electromagnetic type. Further the diameter of the branch line 215 may be smaller than the diameter of the first line 211, the branch line 215 may be understood as detecting a sample of the water in the first flush tank 100. That is, in order to prevent the water in the first wash water tank 100 from flowing through the first pipe 211 too quickly, the water in the first wash water tank 100 is flowed through by using the branch pipe 215 having a small diameter.

The second water inlet 2133 of the heat exchanger 213 is communicated with an external water source, such as a tap water pipe, the second water outlet 2134 of the heat exchanger 213 is communicated with one end of a second pipe 212, the other end of the second pipe 212 is communicated with the a1 water inlet 110 of the first water washing tank 100, and the second pipe 212 is provided with a second electromagnetic control valve 217.

The second solenoid control valve 217 may be identical to the first solenoid control valve 214.

The control module 300 is electrically connected to the first solenoid control valve 214, the absorbance detection sensor 216, and the second solenoid control valve 217, respectively, as shown in fig. 2. The control module 300 can be a PLC controller or a single chip microcomputer.

In the present embodiment, in the initial case, the control module 300 causes the first solenoid-operated valve 214 and the second solenoid-operated valve 217 to remain closed while causing the absorbance detection sensor 216 to start operating. The heating module 130 heats the water in the first wash water tank 100 and maintains the water in the first wash water tank 100 at a desired temperature, the water in the first wash water tank 100 is discharged from the water outlet 120 of the a2 along the branch line 215 of the first line 211, the absorbance detection sensor 216 can detect and acquire the absorbance of the water passing through the branch line 215 and transmit the detected absorbance value to the control module 300, and the control module 300 can process and compare the absorbance value with a set threshold value, for example, directly compare the absorbance value with the threshold value, or multiply the detected absorbance value with a related detection error coefficient to obtain an actual absorbance value, and compare the actual absorbance value with the threshold value. The control module 300 causes the first and second control valves to open if the current absorbance value is greater than a threshold set by the control module 300. At this time, the water in the first wash water tank 100 flows into the first water inlet 2131 of the heat exchanger 213 from the water outlet 120 of a2 along the first pipeline 211, the external water source flows into the second water inlet 2133 of the heat exchanger 213, the external water source exchanges heat with the water source entering the first water inlet 2131, and the temperature of the external water source is increased; the water source entering the first water inlet 2131 is then discharged from the first water outlet 2132 and the water source entering the second water inlet 2133 enters the a1 water inlet 110 of the first flush tank 100 from the second water outlet 2134 along the second conduit 212. Since the external water source is heat-exchanged with the water source flowing out of the first wash water tank 100, the temperature of the external water source is increased, so that the heating time of the heating module 130 can be reduced, thereby reducing the production cost; in addition, since the external water source continuously enters the first wash water tank 100, thereby causing the color depth in the first wash water tank 100 to decrease, the absorbance detected by the absorbance detection sensor 216 is lower than the threshold set by the control module 300, and the control module 300 closes the first and second electromagnetic control valves 214 and 217 again. The embodiment can detect the color depth in the first wash water tank 100 in real time, so as to judge whether water needs to be added into the first wash water tank 100, and the problem that the water use cost is increased in the existing scheme of periodically injecting quantitative water into the wash water tank can be well avoided.

In order to better filter impurities, such as floating color, fiber, etc., in the water flowing out of the water outlet 120 of the a2 of the first water washing tank 100, in one embodiment, referring to fig. 3, the first pipe 211 is provided with a filtering module 218. The filter module 218 can remove impurities of the water body discharged from the first wash water tank 100 well. Wherein, the filtering module 218 comprises a filtering net and a filtering tank, wherein the filtering net is arranged at the water inlet of the filtering tank. The mesh number of the filter screen can be 200-300 meshes. For example, the mesh number of the filter net is 200 mesh, 220 mesh, 250 mesh, 300 mesh, or the like.

Considering that at least two water washing tanks may be required to wash cloth during the washing process of cloth, for this reason, a problem of how to replenish water when two or more water washing tanks are included in the cloth washing needs to be considered. In one embodiment, referring to FIG. 4, the intelligent water saving system further comprises a second flush tank 400, wherein second flush tank 400 comprises a B1 water inlet 410 and a B2 overflow 420, and the B2 overflow 420 of second flush tank 400 is higher than the A1 water inlet 110 of first flush tank 100 in the vertical direction, for example, the height of second flush tank 400 may be designed to be higher than first flush tank 100 or second flush tank 400 may be placed at a higher position than first flush tank 100 such that the B2 overflow 420 of second flush tank 400 is higher than the A1 water inlet 110 of first flush tank 100. In addition, a heating module 130 is also provided in the second water washing tank 400. The B1 inlet 410 of the second flush tank 400 communicates with the end of the second conduit 212 remote from the second outlet 2134, i.e. the above embodiment has been modified to refill the a1 inlet 110 of the first flush tank 100 with the second conduit 212, to refill the B1 inlet 410 of the second flush tank 400. And overflows into the first water washing tank 100 when the height of the water in the second water washing tank 400 meets an overflow requirement, and particularly, the water flow pipeline 200 further includes an overflow pipeline 220, wherein one end of the overflow pipeline 220 is communicated with the B2 overflow port 420 of the second water washing tank 400, and the other end of the overflow pipeline 220 is communicated with the a1 water inlet 110 of the first water washing tank 100.

The idea of this embodiment is that, when the absorbance value detected by the absorbance detection sensor 216 exceeds the threshold value of the control module 300, water is first supplied to the second wash water tank 400, and when the supplied water in the second wash water tank 400 reaches the overflow port, the supplied water is overflowed into the first wash water tank 100 through the overflow pipe. The reason for this consideration is that the first wash water tank 100 is a first-pass washing tank for cloth, the second wash water tank 400 is a second-pass washing tank for cloth, and therefore the color depth of the first wash water tank 100 is higher than or not less than that of the second wash water tank 400, so that the color depth in the second wash water tank 400 can be reduced on the one hand by supplementing water into the second wash water tank 400, and simultaneously, water with a lower color depth in the second wash water tank 400 overflows into the first wash water tank 100, thereby reducing the water color depths of the first wash water tank 100 and the second wash water tank 400.

When the cloth needs to be washed by multiple times, that is, when more than two wash tanks are needed, for example, four wash tanks, referring to fig. 5, a third wash tank 500 and a fourth wash tank 600 may be disposed, where in the vertical direction, the height of the overflow port of the third wash tank 500 is higher than the height of the water inlet of the second wash tank 400, the height of the overflow port of the fourth wash tank 600 is higher than the height of the water inlet of the third wash tank 500, and the second pipeline 212 may replenish water to at least one of the second wash tank 400, the third wash tank 500, and the fourth wash tank 600, for example, the fourth wash tank 600 is adopted in fig. 5. It should be noted that overflow pipes, i.e., three overflow pipes, are provided between the first flush tank 100, the second flush tank 400, the third flush tank 500, and the fourth flush tank 600.

Further, in order to facilitate the transfer of cloth between first flush water tank 100 and second flush water tank 400, in one embodiment, a transfer mechanism is further provided between first flush water tank 100 and second flush water tank 400.

Specifically, the conveying mechanism comprises a first guide roller and a second guide roller which are opposite up and down and can rotate around the axis of the conveying mechanism, and a conveying channel for the cloth to pass through is formed between the first guide roller and the second guide roller. That is to say, the cloth is between first deflector roll and second deflector roll, and when first deflector roll and second deflector roll rotated around its respective axis, the drive cloth conveying. Wherein a first guide roller and a second guide roller may be provided in both the first wash water tank 100 and the second wash water tank 400. In addition, a bending roll may be further provided between the first and second water washing tanks 100 and 400 to widen the cloth and a padder to dry the cloth.

The invention further provides a control method, which is shown in fig. 6 and is used for controlling the intelligent water-saving system, and the control method specifically comprises the following steps:

s110, the control module 300 controls the absorbance detection sensor 216 to work and controls the first electromagnetic control valve 214 and the second electromagnetic control valve 217 to be closed respectively;

s120, detecting the absorbance value of the water body flowing through the first pipeline 211 by the absorbance detection sensor 216, and transmitting the absorbance value to the control module 300;

s130, the control module 300 compares the absorbance value with a threshold value set in the control module 300, and when the absorbance value is greater than the threshold value, the control module 300 simultaneously opens the first solenoid control valve 214 and the second solenoid control valve 217.

In the control method of the present embodiment, the control module 300 controls the operation of the absorbance detection sensor 216 and controls the first solenoid-operated valve 214 and the second solenoid-operated valve 217 to be kept closed in the initial condition. When the absorbance value detected by the absorbance detection sensor 216 exceeds the threshold value of the control module 300, the control module 300 opens the first and second solenoid-operated valves 214 and 217, thereby replenishing water to the first wash water tank 100 through the water flow line 200. When the absorbance value detected by the absorbance detection sensor 216 is equal to or less than the threshold value of the control module 300, the control module 300 closes the first and second solenoid-operated valves 214 and 217 again at this time.

The invention also provides a cloth production line which comprises the intelligent water-saving system. The intelligent water-saving system can play a better water-saving effect by being added in a cloth production line, and the following table can be specifically referred.

Comparison results	Length of processing code	Length of working	Consuming water (ton)	Water consumption (ton/thousand yard)
					Existing solutions	20000	6	49	2.45
This scheme	20000	6	34.3	1.72

By giving a comparison in the above table, under the condition that the cloth processed in 6 hours is 20000 yards, the total water consumption of the existing scheme is 49 tons, and the water consumption of each thousand yards of cloth is 2.45 tons, in the scheme, under the condition of the cloth processed in the same time and the same processing length, the total water consumption of 34.3 tons is less than that of the existing scheme, and the water consumption of each thousand yards of cloth is 1.72 tons is less than that of each thousand yards of cloth in the existing scheme. Therefore, when the intelligent water-saving system is introduced into a cloth production line, the waste of water sources can be reduced, and the use cost of water can be reduced.
