[0002] Water treatment refers to the purification of water through physical, chemical, or biological methods to meet certain usage standards. The main purpose of water treatment is to improve water quality and make it suitable for specific uses. Low-salt food wastewater zero-discharge treatment refers to the treatment of food processing wastewater containing low salt content to achieve a high efficiency reduction of salt and pollutants in the wastewater, ultimately achieving a recycling rate of over 99% and no further discharge of liquid into the environment. In the process of low-salt food wastewater zero-discharge treatment, an air flotation device can be used for auxiliary operations.

Detailed Implementation

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1-3 As shown, an air flotation device for zero-discharge treatment of low-salt food wastewater includes a treatment tank 1, a drive assembly 7, and a collection assembly 8. An aeration device 2 is installed at the bottom of the treatment tank 1, and a filter plate 3 is installed on the inner side of the treatment tank 1. Movable sliders 4 are installed on both sides of the bottom of the filter plate 3. Limiting blocks 5 are fixedly connected to the top two sides of the movable sliders 4, and the bottom of the filter plate 3 is engaged with the limiting blocks 5. A fixed rod 6 is movably connected through the center of the movable sliders 4, and the end of the fixed rod 6 is welded to the side wall of the treatment tank 1. The drive assembly 7 is located above the filter plate 3 and includes a fixed block 701, a drive motor 702, a limiting screw 703, a limiting rod 704, a square slider 705, a protruding block 706, a movable block 707, and a connecting block 708. The fixed block 701 is welded to the top of the treatment tank 1 and is fixed... A drive motor 702 is provided on one side of the fixed block 701, and the output shaft of the drive motor 702 is fixedly connected to a limit screw 703 via a coupling. The end of the limit screw 703 is rotatably connected to the fixed block 701. A limit rod 704 is provided on one side of the limit screw 703, and the end of the limit rod 704 is fixedly connected to the fixed block 701. A square slider 705 is provided on the outer side of the limit screw 703 and the limit rod 704. A protruding block 706 is fixedly connected to one bottom side of the square slider 705. A movable block 707 is rotatably connected to the other bottom side of the square slider 705 via a damping shaft. The filter plate 3 is located between the protruding block 706 and the movable block 707. Connecting blocks 708 are welded to the sides of both the protruding block 706 and the movable block 707. The connecting blocks 708 are fixedly connected to each other by bolts.

[0025] The specific operation is as follows: The operator engages the bottom of the filter plate 3 between the limiting blocks 5 fixedly connected to the top two sides of the movable slider 4, and rotates the movable block 707 in the drive assembly 7, so that the top of the filter plate 3 is engaged between the protruding block 706 and the movable block 707. Then, bolts are used to fix the connecting block 708 welded to the side of the protruding block 706 and the movable block 707, thereby stably positioning the filter plate 3. Next, the aeration device 2 is used to supply gas into the treatment tank 1, so that the impurities inside the treatment tank 1 are aerated by the gas. The bubbles adhere and rise, and then the drive assembly 7 drives the filter plate 3 to move. The drive motor 702 drives the limit screw 703 to rotate, causing the square slider 705 connected to the outside of the limit screw 703 to move. This causes the square slider 705 on the outside of the limit rod 704 on the other side to drive the filter plate 3 to move accordingly. Thus, the filter plate 3 collects the impurities in the treatment tank 1. The structure is simple and convenient for staff to collect and treat the impurities. It is also convenient for staff to use the flotation device for zero discharge treatment of low-salt food wastewater.

[0026] like Figure 1 and Figure 4 As shown, the collection assembly 8 is disposed on both sides of the top of the processing pool 1, and the collection assembly 8 includes a collection frame 801, a connecting rack 802, a fixing plate 803, a servo motor 804, a rotating rod 805, a rotating gear 806, a lifting component 807, and a limiting component 808. The collection frame 801 contacts the inner wall of the processing pool 1, and the connecting rack 802 is welded to one side of the top of the collection frame 801. The fixing plate 803 is disposed on one side of the top of the connecting rack 802, and the fixing plate 803 is welded to the top of the processing pool 1. The servo motor 804 is disposed on one side of the fixing plate 803, and the output shaft of the servo motor 804 is fixedly connected to the rotating rod 805 through a coupling. Furthermore, a rotating gear 806 is fixedly connected to the outer wall of the end of the rotating rod 805, and the rotating gear 806 meshes with the connecting rack 802 for rotational connection. A lifting component 807 is welded to the other side of the top of the collection frame 801, and a limiting component 808 is provided on the outer side of the top of the lifting component 807. The limiting component 808 is welded to the top of the treatment tank 1. An electro-adsorption device 9 is provided on one side of the treatment tank 1. An inlet pipe 10 is fixedly connected to one side of the electro-adsorption device 9, and a pump 11 is fixedly connected to one end of the inlet pipe 10. A drain pipe 12 is fixedly connected to the other side of the pump 11, and one end of the drain pipe 12 is fixedly connected to the bottom of one side of the treatment tank 1.

[0027] The specific operation is as follows: When impurities gradually gather on both sides of the treatment tank 1 under the push of the filter plate 3, the collection component 8 is used to lift the impurities. The servo motor 804 drives the rotating rod 805 to rotate, so that the rotating gear 806 fixedly connected to the outer wall of the end of the rotating rod 805 rotates accordingly and gradually meshes with the connecting rack 802 welded to the top side of the collection frame 801. As the rotating gear 806 rotates, the collection frame 801 is gradually lifted, thereby lifting the impurities and making it easier for the staff to clean them. Subsequently, the pump 11 is used to extract the treated liquid, so that the liquid is discharged from the drain pipe 12 at the bottom of one side of the treatment tank 1 and enters the electro-adsorption device 9 from the inlet pipe 10 fixedly connected to one side of the electro-adsorption device 9. The charged electrode surface adsorbs ions and charged particles in the water, so that dissolved salts and other charged substances in the water are enriched and concentrated on the electrode surface, thereby achieving water purification or desalination. The structure is simple and convenient for staff to use the flotation device for zero discharge treatment of low-salt food wastewater.

[0028] In summary, the air flotation device used for zero-discharge treatment of low-salt food wastewater is based on... Figures 1-4The structure shown illustrates the use of the air flotation device in the zero-discharge treatment of low-salt food wastewater. First, the operator engages the bottom of the filter plate 3 between the limiting blocks 5 fixedly connected to the top of the movable slider 4 on both sides. Then, the movable block 707 in the drive assembly 7 is rotated, causing the top of the filter plate 3 to engage between the protruding block 706 and the movable block 707. Next, bolts are used to fix the connecting block 708 welded to the sides of the protruding block 706 and the movable block 707, thus securing the filter plate 3. Then, the aeration device 2 supplies gas into the treatment tank 1, causing impurities inside the tank 1 to be attached to the air bubbles and rise. The drive assembly 7 then moves the filter plate 3, and the drive motor 702 rotates the limiting screw 703, causing the square slider 705 rotatably connected to the outside of the limiting screw 703 to move. This causes the square slider 705 on the outside of the other limiting rod 704 to move the filter plate 3 accordingly, thereby using the filter plate 3 to filter the impurities in the treatment tank 1. As impurities gradually gather on both sides of the treatment tank 1 under the push of the filter plate 3, the collection component 8 lifts the impurities. The servo motor 804 drives the rotating rod 805 to rotate, causing the rotating gear 806 fixedly connected to the outer wall of the end of the rotating rod 805 to rotate as well. The gear 806 gradually meshes with the connecting rack 802 welded to the top side of the collection frame 801. As the rotating gear 806 rotates, the collection frame 801 is gradually lifted, thus lifting the impurities and making it easier for the staff to clean them. Subsequently, the pump 11 is used to extract the treated liquid, which is discharged from the drain pipe 12 at the bottom of one side of the treatment tank 1 and enters the electro-adsorption device 9 through the inlet pipe 10 fixedly connected to one side of the electro-adsorption device 9. The charged electrode surface adsorbs ions and charged particles in the water, causing dissolved salts and other charged substances in the water to be enriched and concentrated on the electrode surface, thereby achieving water purification or desalination. The structure is simple and convenient for staff to use for zero-discharge treatment of low-salt food wastewater. (The model of the electroadsorption device 9 is NTK-2000T)
