Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically an electrochemical device for treating ink wastewater that integrates oxidation, flocculation, and air flotation. Background Technology

[0002] The device used in ink wastewater treatment integrates oxidation, flocculation, and flotation, which is a highly efficient comprehensive treatment technology that significantly improves pollutant removal efficiency through synergistic effects. Flocculants are added to the ink wastewater treatment equipment. Oxidative flocculation is a technology used in water treatment, mainly to accelerate the aggregation of suspended particles, promote the separation of particles from the solution, and thus improve treatment efficiency.

[0003] Oxidized small-molecule organic matter is more easily captured by flocculants, improving flocculation efficiency. The dissolved air system in ink wastewater treatment equipment generates 20-50 micron microbubbles, which adhere to the flocs to form flocs. Since the density is lower than that of water, the flocs float quickly to the water surface, causing the flocs to accumulate on the water surface, which is not convenient for subsequent automatic centralized cleaning.

[0004] Therefore, it is necessary to propose an electrochemical device that integrates oxidation, flocculation, and flotation for treating ink wastewater. Utility Model Content

The first support plate 21 and the second support plate 22 are respectively fixedly installed at both ends of one side of the dissolved air flotation machine 1. The electrical control box 28 is installed on the first support plate 21 and is electrically connected to a geared motor 27, a hydraulic cylinder 33, and a water pump 37. A first connecting block 23 is rotatably installed on the inner side of the first support plate 21, and the first support plate 21 is used to support and install the first connecting block 23. A second connecting block 24 is rotatably installed on the inner side of the second support plate 22, and the second support plate 22 is used to support and install the second connecting block 24. A geared motor 27 is installed on the outer side of the first support plate 21, and the output end of the geared motor 27 is connected to the first connecting block 23. The geared motor 27 is used to drive the first connecting block 23 to rotate. The rotation position of the first connecting block 23 can be controlled by the operator without precise position control. A connecting rod 25 is fixedly installed between the first connecting block 23 and the second connecting block 24. The first connecting block 23 and the second connecting block 24 are connected by the connecting rod 25 to increase the stability of the first connecting block 23 and the second connecting block 24 and to enable the first connecting block 23 and the second connecting block 24 to rotate synchronously. One end of the first connecting block 23 and the second connecting block 24 is fixedly connected to the scooping screen 26. The first connecting block 23 and the second connecting block 24 are used to support the rotation of the scooping screen 26. When the scooping screen 26 is reset and stationary, it is placed vertically inside the dissolved air flotation machine 1. When the scooping screen 26 rotates and flips, it is used to scoop and process the flocculent floating inside the dissolved air flotation machine 1.

[0028] Furthermore, the collection component 3 includes a collection box 31, a first support frame 32, and a valve 39. The collection box 31 is located on one side of the dissolved air flotation machine 1 and is used to collect flocculants. The first support frame 32 is fixedly installed at both ends of the collection box 31 and is used to support the installation of the hydraulic cylinder 33. The valve 39 is installed at one end of the collection box 31. When the valve 39 is opened, it is used to discharge the flocculants in the collection box 31. The hydraulic cylinder 33 is installed on the top of the first support frame 32 and is used to support the lifting and adjusting height of the pipeline 36. The output end of the hydraulic cylinder 33 is connected to a second support frame 35, which is used to support the installation of the pipeline 36. A guide rod 34 is fixedly installed on the top of the second support frame 35. 4 is used to guide the movement of the second support frame 35.

The wide-angle nozzle 362 is easy to disassemble and maintain. Water is sprayed onto the scooping screen 26 through the wide-angle nozzle 362 to wash away the flocculent on the scooping screen 26. When the wide-angle nozzle 362 sprays water, the spray range of the wide-angle nozzle 362 covers the scooping screen 26, but will not wash the flocculent on the scooping screen 26 outside the collection box 31.

[0029] A water pump 37 is installed at one end of the first support frame 32. The water pump 37 is connected to an external water source through a water pipe, and water is introduced into the corrugated pipe 38 through the water pump 37.

The corrugated pipe 38 connects the water pump 37 and the pipe network 36, and water is introduced into the pipe network 36 through the corrugated pipe 38. At the same time, the corrugated pipe 38 does not affect the raising and lowering of the pipe network 36.

[0030] The working principle of this utility model is as follows: When the scooping screen 26 is in its reset and stationary state, it is placed vertically inside the dissolved air flotation machine 1. The control box 28 drives the reduction motor 27, which in turn drives the scooping screen 26 to rotate. After rotating and rotating, the scooping screen 26 is used to scoop and process the flocculent material floating inside the dissolved air flotation machine 1. The scooping screen 26 moves above the collection box 31, and the hydraulic cylinder 33 controls the pipeline 36 to descend to a position 5-10 cm above the scooping screen 26. The water pump 37 is connected to an external water source through a water pipe, and the water... Pump 37 introduces water into corrugated pipe 38, which in turn introduces water into pipe network 36. At the same time, corrugated pipe 38 does not affect the raising and lowering of pipe network 36. Water then enters the connecting pipe 361 through pipe network 36, and finally into wide-angle nozzle 362 through connecting pipe 361. Water is then sprayed onto the scooping screen 26 through wide-angle nozzle 362 to rinse it. The rinsing range of wide-angle nozzle 362 can completely cover the scooping screen 26, causing the flocculent material on the scooping screen 26 to be rinsed and fall into collection box 31. After rinsing, the scooping screen 26 is flipped back and placed vertically inside dissolved air flotation machine 1.

[0031] In summary, by setting up a flocculant treatment mechanism on one side of the dissolved air flotation machine, the scooping screen 26 is placed inside the dissolved air flotation machine when it is stationary. By driving the scooping screen 26 to flip, it is easy to automatically clean the flocculants that have gathered on the water surface. Water is sprayed onto the scooping screen 26 through the wide-angle nozzle 362 to rinse and wash away the flocculants and collect them in a concentrated manner.
