[0002] With the continuous development of society and the continuous progress of science, people are paying more and more attention to the environment. In order to prevent the direct discharge of wastewater from polluting the environment, wastewater is usually treated. The treatment of dyeing and printing wastewater is one type of wastewater treatment. Dyeing and printing wastewater needs to be decolorized, which usually requires the addition of decolorizing flocculants to react. This can cause the suspended particles in the dyeing and printing wastewater to form flocs and quickly settle out of the water. These precipitated impurities are not easy to clean inside the dyeing and printing wastewater decolorization equipment, and will accumulate inside the equipment over time, affecting the use of the equipment and reducing the efficiency of the dyeing and printing wastewater decolorization process. Currently, filtration is carried out through separation devices. Due to the different fiber contents in the liquid, when the fiber content is high, it will cause the water flow rate to decrease.

[0025] This specific embodiment is a decolorization device for dyeing and printing wastewater, and its structural schematic diagram is shown below. Figures 1-7 As shown, it includes: a mixing tank 2 and a filter shell 5 installed at its top. A sealing cover 6 is installed on the top surface of the filter shell 5. A stirring paddle 16 is installed through the inside of the mixing tank 2. A motor 15 is installed at the bottom of the mixing tank 2, and the bottom of the stirring paddle 16 is fixedly connected to the output end of the motor 15. A circulation pump 14 is installed on the outer surface of the mixing tank 2. A drain pipe 7 and a water inlet pipe 1 are installed at the output and input ends of the circulation pump 14, respectively. The ends of the drain pipe 7 and the water inlet pipe 1 that are far apart from each other are installed through the filter shell 5 and the mixing tank 2, respectively. A wastewater pipe 23 and a water outlet pipe 17 are installed through the bottom surface of the mixing tank 2, respectively. A drug delivery mechanism is provided on the outside of the mixing tank 2, and the drug delivery mechanism is installed through the drain pipe 7. A filtration mechanism is installed inside the filter shell 5.

[0026] Specifically, by connecting the outlet pipe 17 and the wastewater pipe 23 to the water pump, the water pump draws a quantitative amount of wastewater into the mixing tank 2 through the wastewater pipe 23. Then, the motor 15 drives the stirring paddle 16 to rotate and stir. Then, the circulation pump 14 starts and draws the wastewater from the mixing tank 2 through the inlet pipe 1 and drops it onto the filter mechanism through the drain pipe 7 for filtration. After filtration, the filtered water falls back into the mixing tank 2 for circulation. Under the action of the dosing mechanism, decolorizing and flocculant solution is added to the wastewater. Under the action of the circulation pump 14, the wastewater circulates. Under the action of the motor 15 and the stirring paddle 16, the circulating wastewater flows radially to ensure that the wastewater and the decolorizing and flocculant solution are fully in contact, improve the mixing uniformity, ensure the efficacy of the drug, accelerate the decolorization and flocculant of the wastewater, and improve the wastewater treatment efficiency. After the wastewater is purified, it is discharged by the water pump through the outlet pipe 17.

[0027] Furthermore, a bracket 4 is installed on the bottom surface of the filter housing 5.

[0028] Specifically, the bracket 4 supports the filter housing 5, increasing the stability of the filter housing 5.

[0029] Furthermore, a sealing door 24 is installed on the right end of the filter housing 5.

[0030] Specifically, the end of the filter housing 5 away from the mixing tank 2 is opened through the sealing door 24 to facilitate cleaning of the inside of the filter housing 5.

[0031] Furthermore, a drain head 18 is provided inside the front filter housing 5, and the drain pipe 7 is installed through the drain head 18.

[0032] Specifically, the drain head 18 disperses the wastewater discharged from the drain pipe 7, preventing the wastewater discharged from the drain pipe 7 from concentrating and causing impurities to accumulate locally on the filter mechanism, leading to blockage.

[0033] Furthermore, a viewing window 3 is installed through the outer surface of the mixing tank 2, and the outer surface of the viewing window 3 is provided with scale.

[0034] Specifically, this allows users to easily view the waste liquid volume and decolorization effect in mixing tank 2.

[0035] Furthermore, the drug delivery mechanism includes a metering pump 9, with a drug delivery tube 8 and a drug extraction tube 10 installed at the output and input ends of the metering pump 9, respectively. The drug extraction tube 10 is installed inside the medicine bottle 11, and a connector 12 is installed through the outer surface of the drain pipe 7, with a one-way valve 13 installed through the outer surface of the connector 12.

[0036] Specifically, the dosing tube 8 and connector 12 are connected first. When the circulating pump 14 draws wastewater through the inlet pipe 1 and the outlet pipe 7, the metering pump 9 is started to draw the medicine liquid in the medicine bottle 11 through the extraction pipe 10. The medicine liquid enters the outlet pipe 7 through the dosing tube 8 and connector 12. Under the action of the metering pump 9, the medicine liquid is slowly drawn into the outlet pipe 7 and comes into contact with the rotating wastewater in the outlet pipe 7, which further increases the uniformity of the contact between the medicine liquid and the wastewater and increases the wastewater purification efficiency.

[0037] Furthermore, the filtration mechanism includes a conveyor 19 installed inside the filter housing 5, and the conveyor belt of the conveyor 19 is made of filter screen material. A baffle 20 is installed on the outer surface of the conveyor belt of the conveyor 19. An air nozzle 21 is installed inside the conveyor 19 and is located inside the conveyor belt of the conveyor 19. An air pump 22 is installed inside the filter housing 5 and is installed through the air pump 22 and the air nozzle 21.

[0038] Specifically, during use, the conveyor 19 starts and rotates with its filter material conveyor belt. The drain pipe 7 discharges wastewater and flocculated impurities onto the filter material conveyor belt of the conveyor 19. The wastewater is filtered by the conveyor 19 and falls into the mixing tank 2. As the filter material conveyor belt of the conveyor 19 rotates, it moves with flocculated impurities to below the jet nozzle 21. The air pump 22 blows air through the jet nozzle 21 onto the filter material conveyor belt of the conveyor 19. The flocculated impurities on the surface of the filter material conveyor belt fall into the right end of the filter shell 5, thereby continuously cleaning the filter material conveyor belt of the conveyor 19, preventing clogging during use, and ensuring wastewater filtration efficiency.

[0039] This utility model discloses a decolorizing device for dyeing and printing wastewater. Both the outlet pipe 17 and the wastewater pipe 23 are connected to a water pump. The water pump draws a quantitative amount of wastewater into the mixing tank 2 through the wastewater pipe 23. Then, a motor 15 drives a stirring paddle 16 to rotate and stir the wastewater. Next, a circulation pump 14 is started, drawing wastewater from the mixing tank 2 through the inlet pipe 1 and draining it through the outlet pipe 7 to a filtration mechanism for filtration. After filtration, the wastewater falls back into the mixing tank 2 for circulation. A decolorizing and flocculant solution is added to the wastewater by a dosing mechanism. The circulation pump 14 causes the wastewater to circulate, while the motor 15 and the stirring paddle 16 reduce the radial flow of the circulating wastewater, ensuring sufficient contact between the wastewater and the decolorizing and flocculant solution, improving mixing uniformity, ensuring the effectiveness of the solution, accelerating wastewater decolorization and flocculation, and improving wastewater treatment efficiency. After purification, the wastewater is discharged by the water pump through the outlet pipe 17.

[0040] Next, the dosing tube 8 and connector 12 are connected. When the circulating pump 14 draws wastewater through the inlet pipe 1 and the outlet pipe 7, the metering pump 9 is started to draw the medicine liquid in the medicine bottle 11 through the medicine drawing pipe 10. The medicine liquid enters the outlet pipe 7 through the dosing tube 8 and connector 12. Under the action of the metering pump 9, the medicine liquid is slowly drawn into the outlet pipe 7 and comes into contact with the rotating wastewater in the outlet pipe 7, which further increases the uniformity of the contact between the medicine liquid and the wastewater and increases the wastewater purification efficiency.

[0041] Then, the conveyor 19 starts and rotates with its filter material conveyor belt. The drain pipe 7 discharges wastewater and flocculated impurities onto the filter material conveyor belt of the conveyor 19. The wastewater is filtered by the conveyor 19 and falls into the mixing tank 2. As the filter material conveyor belt of the conveyor 19 rotates, it moves with flocculated impurities to below the jet nozzle 21. The air pump 22 blows air through the jet nozzle 21 to blow air onto the filter material conveyor belt of the conveyor 19. The flocculated impurities on the surface of the filter material conveyor belt fall into the right end of the filter shell 5, thereby achieving continuous cleaning of the filter material conveyor belt of the conveyor 19, preventing blockage during use, and ensuring wastewater filtration efficiency.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
