[0055] This application proposes a smart dosing device for achieving the effect of automated dosing treatment of dye wastewater during the treatment process, which is as follows:

[0056] For reference Figure 1The present application is mainly constructed on the liquid storage tank 1, the decolorization tank 2 and the flocculation tank 3. The liquid storage tank 1, the decolorization tank 2 and the flocculation tank 3 cooperate with the intelligent dosing device of the present application, during which the fine solid particles in the wastewater can be effectively aggregated into larger flocs and discharged into the sedimentation tank for the sedimentation step, providing convenience for subsequent treatment or discharge work.

[0057] For reference Figure 1 The present application is mainly composed of a water quality detection component 4 arranged on a liquid storage tank 1 for detecting the water quality concentration in the liquid storage tank 1, a coagulant delivery component 6 arranged in the middle of the connection between the liquid storage tank 1 and the decolorization tank 2, and a control system 7 for controlling the operation of the intelligent dosing device. In this way, after the wastewater is uniformly discharged into the liquid storage tank 1, the wastewater concentration is automatically detected, and the numerical value is transmitted to the control system 7 for calculation. The decolorization solution delivery component 5 and the coagulant delivery component 6 are controlled by calculation to add ferrous sulfate solution and coagulant polyacrylamide in equal proportions. The entire process is built with an intelligent system, which can reduce manpower investment, has a fast calculation speed, and improves the fluency of wastewater treatment.

[0058] It should be noted that the control system 7 can be built near the liquid storage tank 1, the decolorization tank 2 and the flocculation tank 3. Its automatic connection control is a common setting at present, and this application will not go into details.

[0059] For reference Figure 1-6 The water quality detection components 4 are arranged on the liquid storage tank 1, and at least two groups are arranged. The height of the arrangement position is not limited. When arranging the multiple groups of water quality detection components 4, it is sufficient to avoid the spacing being too close.

[0060] The water quality detection component 4 realizes water quality concentration detection of the wastewater inside the liquid storage tank 1, and mainly includes a quantitative waste liquid discharge unit 41, a waste liquid receiving and shaking unit 42, a titration unit 43, a detection unit 44 and a waste liquid discharge unit 45; in specific operation, the waste liquid is first taken out from the liquid storage tank 1 through the quantitative waste liquid discharge unit 41 and enters into the waste liquid receiving and shaking unit 42, and then the titrant is slowly dripped into the liquid storage tank 1 through the titration unit 43, and the changes are recorded by the detection unit 44 during this period until obvious color changes or other indication changes are observed, and the amount of titrant used at this time is recorded in the control system 7, and then the wastewater used for detection is discharged back into the liquid storage tank 1 through the waste liquid discharge unit 45 under the control of the control system 7.

[0061] For reference Figure 1-3 and Figure 4The quantitative waste liquid discharge unit 41 is connected to the liquid storage tank 1, and the quantitative waste liquid discharge unit 41 includes an output pipe 411, a first electromagnetic flow valve 412 and a connecting pipe 413; the output pipe 411 is connected to the liquid storage tank 1, and the first electromagnetic flow valve 412 is installed on the output pipe 411. After the wastewater enters the liquid storage tank 1, the first electromagnetic flow valve 412 is opened by the control system 7. At this time, the wastewater flows into the connecting pipe 413, and the output pipe 411 is connected to the connecting pipe 413, so that the wastewater will eventually be discharged through the connecting pipe 413.

[0062] It should be noted that the amount of waste water discharged from the quantitative waste liquid discharge unit 41 is pre-set according to the size of the waste liquid receiving and shaking unit 42. After setting, the control system 7 will control the first electromagnetic flow valve 412 to open and discharge the preferentially set amount.

[0063] For reference Figure 1-3 and Figure 5 The top of the waste liquid receiving shaking unit 42 can be swung at the bottom of the quantitative waste liquid discharge unit 41 through a ball shaft, and the waste liquid receiving shaking unit 42 includes a shaking bottle 421 and a micro electric telescopic rod 422; specifically, the shaking bottle 421 is arranged at the end of the connecting tube 413 away from the output tube 411 through a ball shaft, and the ball shaft is selected to have a through hole in the middle, which can maintain the requirement of the connecting tube 413 to discharge liquid into the shaking bottle 421, and at the same time, the bottom of the inner cavity of the shaking bottle 421 is conical (set for detection requirements); one end of the micro electric telescopic rod 422 is connected to the outer surface of the output tube 411, and the other end is connected to the upper surface of the shaking bottle 421; therefore, when the titration unit 43 controls the dripping of titration liquid into the shaking bottle 421, the micro electric telescopic rod 422 is controlled to start working, and the micro electric telescopic rod 422 will cause the shaking bottle 421 to shake, so as to ensure uniform mixing and observe the changes in the reaction.

[0064] For reference Figure 1-3 It should be noted that the titration unit 43 includes a burette with a control valve, one end of which is fixed and connected to the top of the shaking bottle 421, and the other end is connected to an external titration liquid delivery device. The control system 7 is used to control the switch of the burette to drip the titration liquid into the shaking bottle 421. When the shaking bottle 421 starts to shake, the detection unit 44 synchronously checks the changes in the waste liquid in the shaking bottle 421 and synchronizes it to the control system 7 in real time. When the waste liquid gradually begins to change, the control system 7 controls the control valve of the burette again to slow down the dripping speed and continue dripping until the detection unit 44 observes obvious color changes or other indication changes and transmits them to the control system 7. The control system 7 records the amount of titrant used at this time and synchronously stops the operation of the titration unit 43.

[0065] Furthermore, the control system 7 calculates the concentration of the target substance in the test solution using the chemical reaction equation and related formulas based on the known concentration and dosage of the titrant; and in the configuration of the present application, at least two groups of water quality detection components 4 are provided, so there are at least two groups of titrant dosage data, and the average value is taken according to the two groups of data to improve accuracy. Secondly, when the deviation of at least two groups of titrant dosage data is large, the work is recycled again, and when the same detection situation occurs in the second detection, the control system 7 sends an alarm signal to the maintenance staff; and if the second detection is normal, the subsequent detection work of the device can be continued.

[0066] For reference Figure 1-2 and Figure 6 In order to facilitate the observation of the detection unit 44, a transparent material is selected for the surface of the shaking bottle. The surface is transparent, and the detection unit 44 can observe the waste liquid inside the bottle through the bottle body. The detection unit 44 specifically includes a support rod 441 and a visual sensor 442. The support rod 441 is installed at the end of the output pipe 411 away from the liquid storage tank 1, and the visual sensor 442 is installed at the bottom of the support rod 441 and is set toward the shaking bottle 421. The shape of the support rod 441 is not limited. It can be set to any shape according to the scene requirements and connected to the support rod 441 to support the visual sensor 442 to be set toward the shaking bottle 421.

[0067] For reference Figure 1-2 and Figure 5 After completing the detection of the amount of titration solution used, open the waste liquid discharge unit 45 and discharge the detected waste water back into the liquid storage tank 1; and in order to maintain the shaking work of the waste liquid receiving and shaking unit 42, the top of the waste liquid discharge unit 45 is connected to the waste liquid receiving and shaking unit 42 through a ball shaft, and the other end is connected to the liquid storage tank 1, wherein a through hole is also provided in the middle of the ball shaft, so that the waste liquid can be discharged back into the liquid storage tank 1 after detection.

[0068] Specifically, the waste liquid discharge unit 45 includes a delivery pipe 451 and a second electromagnetic flow valve 452; one end of the delivery pipe 451 is connected to the bottom of the shaking bottle 421 through a ball shaft, and the other end is connected to the liquid storage tank 1, and the second electromagnetic flow valve 452 is arranged on the delivery pipe 451 to control the reflux of the waste liquid; at the same time, a micro water pump is arranged on the delivery pipe 451, which is coordinated with the second electromagnetic flow valve 452; when the control system 7 has recorded the amount of titration liquid, the second electromagnetic flow valve 452 is controlled to open, and the reflux is reduced with the assistance of the micro water pump, so that the waste liquid in the shaking bottle 421 is re-delivered to the liquid storage tank 1 through the delivery pipe 451.

[0069] When the water quality detection component 4 completes all the detection work, the waste water is discharged from the liquid storage tank 1 into the decolorization tank 2 through the control system 7; before discharging the waste water, the control system 7 calculates the waste water concentration in the liquid storage tank 1 based on the above steps, and adds an equal proportion of ferrous sulfate solution through the decolorization solution delivery component 5 to decolorize the dyed residual liquid according to the water quality concentration.

[0070] For reference Figure 1 and Figure 7-8 In order to promote a better fusion effect between the ferrous sulfate solution and the wastewater without stirring, the ferrous sulfate solution input is set to be discharged into the decolorization tank 2 synchronously with the wastewater in the liquid storage tank 1, which relatively reduces the hardware requirements required for the equipment; most of the existing devices have a stirring device on the top of the decolorization tank 2, and the decolorization tanks are mostly large, and subsequent maintenance and other problems are relatively troublesome; while the decolorization solution delivery component 5 in the present application is set at a position close to the ground, which is conducive to subsequent maintenance and repair work, and also reduces the danger of maintenance personnel working at high altitudes during maintenance.

[0071] For reference Figure 1 and Figure 7-8 The decolorizing liquid delivery assembly 5 includes a first drainage pipe 51, a first water pump 52, a first treatment unit 53 and a first infusion pipe 54; specifically, the first treatment unit 53 is mixed with ferrous sulfate solution to enter the first treatment unit 53; specifically, the first drainage pipe 51 is connected to the liquid storage tank 1, the water pumping end of the first water pump 52 is connected to the first drainage pipe 51, and the other end of the first water pump 52 is connected to the first treatment unit 53 through a pipeline, thereby the wastewater is sucked and discharged into the first treatment unit 53 through the first water pump 52. and wait for the first treatment unit 53 to mix with the ferrous sulfate solution and enter the first treatment unit 53; the first treatment unit 53 is connected to one end of the first infusion pipe 54, and the other end of the first infusion pipe 54 is connected to the decolorization tank 2, so that after the ferrous sulfate solution is added, it enters the first infusion pipe 54 together with the wastewater and is discharged into the decolorization tank 2; wherein the diameter of the first infusion pipe 54 is set to be smaller than the diameter of the first discharge pipe 51, which can reduce the flow rate discharged outward and increase the contact between the ferrous sulfate solution and the wastewater in the first treatment unit 53.

[0072] Furthermore, a third electromagnetic flow valve 511 is provided on the first liquid discharge pipe 51. The control system 7 calculates the amount of ferrous sulfate solution to be input based on the above-mentioned wastewater concentration and the total volume of the wastewater, and finally controls the flow rate of the third electromagnetic flow valve 511 to discharge the wastewater outward. The control system 7 then controls the amount and speed of ferrous sulfate solution introduced into the first treatment unit 53 according to the flow rate, thereby ensuring that the ferrous sulfate solution participates in the entire process of wastewater discharge and can be fully fused with the wastewater, thereby reducing the need for subsequent stirring and fusion; secondly, a fourth electromagnetic flow valve 541 is provided on the first infusion pipe 54. Based on the situation in which the control system 7 controls the third electromagnetic flow valve 511, the flow rate and amount of wastewater discharged by the fourth electromagnetic flow valve 541 are reduced, thereby increasing the contact between the ferrous sulfate solution and the wastewater in the first treatment unit 53, and increasing the effect of full fusion of the ferrous sulfate solution and the wastewater.

[0073] For reference Figure 1 and Figure 7 The first processing unit 53 includes a collecting box 531, a stirring member 532 and a drug delivery tube 533. The collecting box 531 is L-shaped as a whole, and one side is connected to the first water pump 52 through a pipeline. The wastewater is first discharged into the collecting box 531 through the first water pump 52, and the L-shaped design can reduce the situation where the wastewater will preferentially contact the first infusion tube 54; the drug delivery tube 533 is connected and arranged on the collecting box 531, and is connected to an external ferrous sulfate solution drug delivery device. When the collecting box 531 receives the wastewater, the drug delivery tube 533 simultaneously discharges an appropriate amount of ferrous sulfate solution into the collecting box 531; and then it is stirred by the stirring member 532 arranged on the collecting box 531 and discharged through the first infusion tube 54.

[0074] Among them, the stirring element 532 and the first water pump 52 are opposite to each other front and back. For example, the stirring element 532 and the first water pump 52 are both arranged on the left side of the collecting box 531 for work, and the first infusion tube 54 is arranged on the right side of the collecting box 531 for work. The divided area work increases the fusion effect between the wastewater and the medicine.

[0075] It should be noted that the stirring member 532 is a combination of a common existing driving motor and a stirring rod, and this application will not elaborate on it.

[0076] For reference Figure 1 and Figure 8-9After entering the decolorization tank 2, based on the addition of ferrous sulfate, the residual liquid to be dyed undergoes a decolorization reaction. In order to realize intelligent and automatic control, a transparent window is set at the bottom of the surface of the decolorization tank 2, and a sensor is installed to observe the situation. The observation situation is transmitted to the control system 7 in real time. The control system 7 judges the decolorization reaction according to the transmission data. After the decolorization requirement is met, the decolorized wastewater in the decolorization tank 2 is controlled to enter the flocculation tank 3 through the coagulant delivery component 6. When the coagulant delivery component 6 delivers the decolorized wastewater, it will be integrated with the coagulant polyacrylamide and the decolorized wastewater into the flocculation tank 3. After the wastewater enters the flocculation tank 3, it is discharged to the sedimentation tank. The mixed liquid treated with flocculation flows into the sedimentation tank. In the sedimentation tank, the flocs will settle to the bottom due to gravity to form a precipitate. The precipitate at the bottom of the sedimentation tank is discharged regularly to remove the removed solids, and the clear liquid is extracted from the upper part for subsequent treatment or discharge.

[0077] For further reference Figure 1 and Figure 8-9 The structure of the coagulant delivery component 6 is roughly similar to that of the decolorizing solution delivery component 5, including a second drainage pipe 61, a second water pump 62, a second treatment unit 63 and a second infusion pipe 64. The second drainage pipe 61 is connected and arranged on the flocculation tank 3. The input end of the second water pump 62 is connected to the second drainage pipe 61, and the second treatment unit 63 is connected to the output end of the second water pump 62. After the wastewater is decolorized, the second water pump 62 is controlled by the control system 7 to start working, and the decolorized wastewater is sucked into the second treatment unit 63 through the second drainage pipe 61, and the coagulant polyacrylamide is added and stirred through the second treatment unit 63; one end of the second infusion pipe 64 is connected to the second treatment unit 63, and the other end is connected to the flocculation tank 3. Pool 3 is connected, the decolorized wastewater added with coagulant polyacrylamide treated by the second treatment unit 63 is thrown into the flocculation tank 3, and the second infusion pipe 64 is connected to the flocculation tank 3 and is arranged at the top position of the surface of the flocculation tank 3, so that the wastewater enters the flocculation tank 3 from top to bottom, and the rolling of the internal liquid is increased again by the impact force of the fall. At the same time, the flocculation tank 3 is connected with the top of the sedimentation tank through the pipeline from the bottom of the surface. When the flocculation tank 3 has half of the wastewater volume, the connecting valve between the flocculation tank 3 and the sedimentation tank is opened, and the wastewater is discharged into the sedimentation tank synchronously, thereby increasing the fusion between the wastewater and the reagent during the flow, and there is no need to set a stirring device on the top of the flocculation tank 3 to increase the difficulty of maintenance.

[0078] To further illustrate, the second processing unit 63 has the same structure as the first processing unit 53, and both have a stirring and conveying structural arrangement, which will not be repeated in this application; while in the first processing unit 53, the drug delivery tube 533 is connected to the ferrous sulfate solution delivery device, and in the second processing unit 63, the drug delivery tube is connected to the external coagulant polyacrylamide delivery device.

[0079] In view of the above, the specific implementation steps of this application are as follows:

[0080] 1. First, the wastewater is put into the liquid storage tank 1, and during the transportation process, a flow valve is set on the transportation pipeline to record the amount of wastewater discharged into the liquid storage tank 1, and the recorded data is synchronously transmitted to the control system 7.

[0081] 2. Secondly, when the wastewater in the liquid storage tank 1 stops being discharged, the control system 7 counts the amount of wastewater, and controls the first electromagnetic flow valve 412 to open and discharge an appropriate amount of wastewater into the shaking bottle 421 and then stops, and then controls the micro-electric telescopic rod 422 to move, and at the same time turns on the titration unit 43 to transport the titrant into the shaking bottle 421. During the shaking process, the visual sensor 442 records the changes and synchronizes them to the control system 7, and the control system 7 also receives the titration status of the control valve of the titration unit 43. During this period, the visual sensor 442 observes the reaction of the wastewater. , when the indication change is observed, the control system 7 records the amount of titrant in the titration unit 43, and stops the titration work of the titration unit 43 and the shaking work of the micro-electric telescopic rod 422, and the water quality detection component 4 is provided with at least two groups, and the control system 7 counts all the data and takes the average value as the final value. When the deviation between the values ​​is large, the control system 7 discharges the detection wastewater into the liquid storage tank 1 and performs another detection. If the detection still has a large deviation, the control system 7 sends an alarm signal to the staff to notify the staff to come for maintenance;

[0082] 3. Then, after taking the intermediate values, the average value is taken to calculate the water quality concentration through the chemical formula, and the flow rate and amount of the ferrous sulfate solution delivered to the collection box 531 by the control system 7 are controlled by the drug delivery tube 533 in proportion; during the delivery of the ferrous sulfate solution, the first water pump 52 synchronously draws wastewater into the collection box 531 to merge with the input ferrous sulfate solution, and the stirring member 532 performs stirring during the fusion to promote the fusion between the ferrous sulfate solution and the wastewater, and then controls the first infusion tube 54 to discharge into the decolorization tank 2 at a lower flow rate than the first discharge tube 51, and waits for the internal wastewater to undergo a decolorization reaction in the decolorization tank 2, and observes through the sensor arranged at the bottom of the decolorization tank 2 (for details, please refer to Figure 8 ), whose data is synchronized to the control system 7. After the control system 7 observes that the decolorization reaches the index according to the data transmitted by the sensor, it controls the coagulant delivery component 6 to work.

[0083] 4. Finally, the coagulant delivery component 6 is controlled by the control system 7. The second water pump 62 first outputs the decolorized wastewater from the second discharge pipe 61 to the second treatment unit 63. Based on the values ​​calculated by the control system 7 in steps 2 and 3, the amount of coagulant polyacrylamide to be input is calculated. The coagulant polyacrylamide and the decolorized wastewater are stirred and blended through the second treatment unit 63, and then discharged into the flocculation tank 3 through the second infusion pipe 64. The wastewater is received at the top position of the flocculation tank 3. After the flocculation tank 3 takes up half of the capacity, the control system 7 opens the switch valve between the flocculation tank 3 and the sedimentation tank, and the wastewater in the flocculation tank 3 is simultaneously discharged from the top position of the sedimentation tank surface into the inner cavity of the sedimentation tank for sedimentation, and subsequent treatment or discharge is performed according to the precipitated wastewater.
