All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a high-efficiency treatment device for dyeing and printing wastewater, including a treatment tank 1, a water level sensor installed inside the treatment tank 1, a support column 2 welded to the bottom of the treatment tank 1 to ensure the overall stability of the device, an outlet pipe 3 riveted to the center of the bottom of the treatment tank 1, and an inlet pipe 4 riveted to the outer wall of the treatment tank 1 for connecting the dyeing and printing wastewater to be treated.

[0025] The top of the treatment tank 1 has a through hole, and a stirring rod 5 is movably connected inside the through hole for necessary stirring of the dyeing and printing wastewater. A rotary motor 6 is installed at the top of the stirring rod 5, and one end of the stirring rod 5 is fixedly connected to the output end of the rotary motor 6. A conveying pipe 7 is riveted to the outer wall of the treatment tank 1 on the side opposite to the inlet pipe 4. A dosing assembly 8 is riveted to the upper end of the conveying pipe 7. The dosing assembly 8 is fixedly connected to one side of the treatment tank 1, and an adjusting component 9 is installed inside the dosing assembly 8.

[0026] refer to Figure 2 An electric valve is installed in the outlet pipe 3 to control the discharge of treated wastewater and ensure that the reaction in the treatment tank 1 is fully carried out.

[0027] refer to Figure 3 , 4 The dosing assembly 8 includes a dose adjustment plate 81, which is a circular plate structure with two drug outlet holes of different diameters. The center of the two drug outlet holes is on the same straight line as the center of the dose adjustment plate 81. The dosage can be controlled by the different sized drug outlet holes.

[0028] A dosing housing 82 is movably connected above the dosing adjustment plate 81. The dosing housing 82 is fixedly connected to the processing tank 1 via a connecting rod. An installation cover 83 is riveted inside the dosing housing 82. A dispensing hopper 84 is welded below the installation cover 83 and is installed inside the dosing housing 82. An opening corresponding to the feed end of the dispensing hopper 84 is opened on the installation cover 83. A drug inlet pipe 71 is fixedly connected to the lower end of the dispensing hopper 84. The outlet of the drug inlet pipe 71 is aligned with the inlet of the conveying pipe 7. The drug is stored in the dispensing hopper 84, enters the dosing adjustment plate 81 through the drug inlet pipe 71, and is conveyed into the conveying pipe 7 through the drug outlet hole on the dosing adjustment plate 81.

[0029] refer to Figure 5 The adjusting assembly 9 is installed inside the dosing housing 82. The adjusting assembly 9 includes a grooved plate 91, which is a square plate with U-shaped grooves at its four corners and arc-shaped grooves on its four sides. The grooved plate 91 is fixedly connected to the dosage adjusting plate 81 via connecting posts. A rotating rod 92 is installed on one side of the grooved plate 91, and a turntable 93 is fitted onto the rotating rod 92. The turntable 93 is a circular disc with a quarter section missing. A lever 94 is welded to the missing section of the turntable 93. A rotary motor 95 is installed at the end; after the rotary motor 95 drives the rotating rod 92 to rotate the turntable 93, so that the lever 94 rotates synchronously and is inserted into the U-shaped groove on the groove plate 91 in sequence, so that the undulating groove plate 91 drives the dosage adjustment plate 81 to rotate 90 degrees in one go. The different drug outlet holes on the dosage adjustment plate 81 are aligned with the drug inlet tube 71 through the adjustment component 9. It should be noted that when the two sides of the unopened hole of the dosage adjustment plate 81 are aligned with the drug inlet tube 71, the drug dispensing stops.

[0030] In this embodiment, the dyeing and printing wastewater is introduced into the treatment tank 1 through the inlet pipe 4. When the amount of dyeing and printing wastewater in the treatment tank 1 reaches a certain level, chemical agents are added through the dosing component 8 and the conveying pipe 7. After the agent enters the treatment tank 1, the rotary motor 6 is started to make the stirring rod 5 rotate, which fully stirs and mixes the dyeing and printing wastewater and the agent in the treatment tank 1.

[0031] The amount of dyeing and printing wastewater in the treatment tank 1 can be determined by the water level sensor installed inside the treatment tank 1. The water level boundary point is set as H, and the actual water level is h.

[0032] When h is greater than H, it indicates that there is a lot of wastewater in the treatment tank 1. At this time, the adjustment component 9 is activated so that the larger diameter drug outlet is aligned with the drug inlet pipe 71. The medicine in the drug hopper 84 enters the treatment tank 1 through the delivery pipe 7. After the set time is reached, the adjustment component 9 is driven again so that the unopened part of the dosage adjustment plate 81 is aligned with the drug inlet pipe 71 and the drug feeding is stopped. At this time, the stirring rod 5 is stirred to mix the wastewater and the medicine.

[0033] When h is less than H, it means that the amount of wastewater in the treatment tank 1 is small. At this time, the adjustment component 9 is activated so that the smaller diameter drug outlet is aligned with the drug inlet pipe 71, and the drug is delivered into the treatment tank 1. After the set time is reached, the adjustment component 9 is driven again so that the unopened part of the dosage adjustment plate 81 is aligned with the drug inlet pipe 71, and the drug delivery is stopped. At this time, the stirring rod 5 is stirred again to mix the wastewater and the drug.

[0034] The above operations can control the dosage of chemical agents to a certain extent, reducing the waste of agents during wastewater treatment; the pollutants in the mixed dyeing and printing wastewater are removed and reduced to a certain extent, and then discharged through the effluent pipe 3.
