Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electroflotation device for cosmetic wastewater. Background Technology

[0002] Cosmetic production generates a large amount of wastewater. To prevent environmental pollution, this wastewater needs to be treated. Currently, the most widely used treatment equipment is electrocoagulation flotation (ECF). ECF uses a high-voltage DC electric field and the physical adsorption principle of bubbles to adsorb and aggregate them into larger bubbles, which are then lifted by buoyancy, thus achieving bubble removal and particulate matter separation. The specific working principle is as follows:

[0003] 1. Electric Field Effect: When a high-voltage DC electric field acts on gases such as air, oxygen, and nitrogen in water, it causes reactions such as polarization, ionization, and discharge of gas molecules. This causes water molecules on the surface of bubbles to contract inward, rapidly removing most of the impurities and suspended matter from the bubble surface. Simultaneously, the electrons and ions generated by gas ionization catalyze the oxidation and reduction of organic and inorganic substances in the water, accelerating water purification.

[0004] 2. Physical Adsorption Effect: A strong electric field will cause the surface of the bubbles to become charged. Positively charged bubbles will adsorb negatively charged particles and contaminants, while negatively charged bubbles will adsorb positively charged particles and contaminants. Thus, under a certain electric field, bubbles and particulate contaminants can effectively and gradually accumulate, eventually forming large bubbles, achieving the purpose of defoaming and decontamination.

[0005] Existing electrocoagulation flotation equipment has low flotation efficiency for bubbles and impurities, requiring the use of more chemicals to treat wastewater, which increases the cost of wastewater treatment.

[0006] To address the aforementioned issues, an improved electroflotation device for cosmetic wastewater is now designed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 In this embodiment of the present invention, the electroflotation device for cosmetic wastewater includes two side plates 9. The two side plates 9 are vertically installed on the upper ends of two opposite side walls of the electrocoagulation flotation device 1. The electrocoagulation flotation device 1 is an existing mature device, and its structure and principles are not specifically described. A second electrode plate 10 is horizontally installed on the side wall of each side plate 9 near the scum discharge end of the electrocoagulation flotation device 1. The polarities of the two second electrode plates 10 are opposite. A plurality of [missing information] are arranged between the two side plates 9 on the side of the second electrode plate 10 away from the scum discharge end of the electrocoagulation flotation device 1. A rotating rod 5 has two ends rotatably connected to a side plate 9. One end of the rotating rod 5 passes through the side plate 9 and is equipped with a motor 3 for driving the rotating rod 5 to rotate. The motor 3 is mounted on the side wall of the side plate 9. A rotating roller 6 is mounted on the side wall of the rotating rod 5 near the side plate 9. A belt 7 is fitted on the rotating roller 6 on the same side. The belt 7 is equipped with an attraction conveying mechanism for guiding charged scum to move towards the scum discharge end of the electrocoagulation flotation equipment 1. The side plate 9 is equipped with an air blowing conveying mechanism for blowing the floating scum towards the scum output end of the electrocoagulation flotation equipment 1.

[0027] The suction and conveying mechanism includes several connecting blocks 11, which are evenly installed on the side wall of the belt 7. A first electrode plate 8 is installed at the end of the connecting block 11 away from the belt 7. A conductive block 13 is installed at the end of the first electrode plate 8 near the side plate 9. A conductive groove 12 that works with the conductive block 13 is horizontally installed at the lower end of the side wall of the side plate 9 near the belt 7. The conductive groove 12 and the first electrode plate 8 at the lower end of the belt 7 are on the same horizontal plane. The conductive block 13 moves in contact with the inner wall of the conductive groove 12. The conductive grooves 12 on the two side plates 9 are respectively connected to the positive and negative terminals of the power supply through wires. The first electrode plate 8 and the second electrode plate 10 on the same side plate 9 have the same polarity. The belt 7 drives the lower first electrode plate 8 to move towards the scum discharge end of the electrocoagulation flotation device 1.

[0028] During use, the bubbles and impurities inside the electro-coagulation flotation device 1 will attract each other and carry an electric charge. Utilizing the principle of opposite charges attracting, the first electrode plate 8 and the second electrode plate 10 attract the bubbles and impurities inside the electro-coagulation flotation device 1, causing the bubbles and impurities in the electro-coagulation flotation device 1 to float up quickly.

[0029] Simultaneously, motor 3 is started. The output end of motor 3 drives rotating rod 5 to rotate, rotating rod 5 drives rotating roller 6 to rotate, rotating roller 6 drives belt 7 to rotate, belt 7 drives connecting block 11 and first electrode plate 8 to move, and the first electrode plate 8 at the lower end of belt 7 moves towards the scum output end of electrocoagulation flotation equipment 1, thereby guiding the floating scum to the scum discharge end of electrocoagulation flotation equipment 1 and discharging it.

[0030] The air blowing and conveying mechanism includes several air pumps 4, which are existing technologies, such as bicycle pumps. The air pumps 4 are installed on the upper end of the side plate 9. The output end of the air pump 4 is equipped with a connecting pipe 2. The end of the connecting pipe 2 away from the air pump 4 passes through the side plate 9 below the conductive groove 12 and is equipped with a nozzle 15 for blowing the scum. The output end of the nozzle 15 faces the scum output end of the electrocoagulation flotation device 1 and is inclined downward. The pressing end of the air pump 4 is provided with a driving component for driving the pressing end of the air pump 4 to move back and forth.

[0031] The drive assembly includes a fixed plate 17. The output end of the air pump 4 faces the belt 7. The fixed plate 17 is installed on the output end of the air pump 4. A spring 16 for pushing the fixed plate 17 away from the air pump 4 is installed on the lower end of the fixed plate 17 near the side wall of the side plate 9. The end of the spring 16 away from the fixed plate 17 is installed on the side wall of the side plate 9. A push block 14 for cooperating with the fixed plate 17 is installed on the end of the conductive block 13 away from the first electrode plate 8. Guide plates 18 for guiding the push block 14 are installed on both sides of the fixed plate 17.

[0032] When the first electrode plate 8 and the conductive block 13 move, the conductive block 13 drives the push block 14 to move. The push block 14 moves along the guide plate 18, thereby pushing the fixed plate 17 closer to the air pump 4. The air pump 4 blows air into the connecting pipe 2, and the connecting pipe 2 discharges gas through the nozzle 15. The nozzle 15 blows the scum towards the scum output end of the electrocoagulation flotation device 1. When the push block 14 moves away from the fixed plate 17, under the action of elasticity, the fixed plate 17 moves away from the air pump 4, causing the air pump 4 to suck in air.

[0033] Working principle of electroflotation equipment for cosmetic wastewater treatment:

[0034] During use, the bubbles and impurities inside the electro-coagulation flotation device 1 will attract each other and carry an electric charge. Utilizing the principle of opposite charges attracting, the first electrode plate 8 and the second electrode plate 10 attract the bubbles and impurities inside the electro-coagulation flotation device 1, causing the bubbles and impurities in the electro-coagulation flotation device 1 to float up quickly.

[0035] Simultaneously, motor 3 is started. The output end of motor 3 drives rotating rod 5 to rotate, rotating rod 5 drives rotating roller 6 to rotate, rotating roller 6 drives belt 7 to rotate, belt 7 drives connecting block 11 and first electrode plate 8 to move, and the first electrode plate 8 at the lower end of belt 7 moves towards the scum output end of electrocoagulation flotation equipment 1, thereby guiding the floating scum to the scum discharge end of electrocoagulation flotation equipment 1 and discharging it.

[0036] When the first electrode plate 8 and the conductive block 13 move, the conductive block 13 drives the push block 14 to move. The push block 14 moves along the guide plate 18, thereby pushing the fixed plate 17 closer to the air pump 4. The air pump 4 blows air into the connecting pipe 2, and the connecting pipe 2 discharges gas through the nozzle 15. The nozzle 15 blows the scum towards the scum output end of the electrocoagulation flotation device 1. When the push block 14 moves away from the fixed plate 17, under the action of elasticity, the fixed plate 17 moves away from the air pump 4, causing the air pump 4 to suck in air.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
