[0002] In the textile processing and production process, printing and dyeing wastewater has the characteristics of complex composition, high suspended solids concentration, and large fluctuations in water quality, making it difficult to treat. At present, traditional printing and dyeing wastewater treatment equipment generally has the following problems in the solid-liquid separation process: 1. Uncontrollable sewage flow rate: Existing equipment makes it difficult to dynamically adjust treatment parameters based on the concentration of suspended solids in sewage. For example, the flow rate of sewage in the flotation tank cannot be effectively controlled, resulting in insufficient attachment time between microbubbles and suspended solids, inadequate flotation reaction, and poor solid-liquid separation. 2. The releaser is prone to clogging: The outlet of the dissolved air water release mechanism is easily clogged by suspended impurities, resulting in a reduction in the amount of dissolved air water released, a decrease in the efficiency of microbubble generation, and even interruption of the solid-liquid separation process, affecting the continuous operation and processing efficiency of the equipment; 3. Incomplete solid-liquid separation: Due to the lack of precise control of the flow state of sewage, suspended solids may not fully float up and be discharged with the water flow, resulting in substandard treated water quality and failure to meet environmental discharge requirements.

[0012] The present invention proposes a wastewater treatment device for textile processing, which has the following beneficial effects: 1. Precisely control the flotation reaction to enhance solid-liquid separation: The device controls the baffle's tilt angle through angle adjustment components (such as screws, guide plates, and racks). This dynamically adjusts the flow resistance of the wastewater in the flotation tank based on the concentration of suspended solids, slowing or accelerating the flow rate. When the suspended solids concentration is high, increasing the baffle's tilt angle reduces the flow rate, allowing microbubbles more time to attach to the surface of the suspended solids, enhancing the flotation reaction and achieving complete solid-liquid separation.

[0013] 2. Automatic blockage clearing function ensures continuous processing: The release assembly uses a linked design of a curved plate and a spiral chute. When the discharge outlet is blocked by impurities, the dissolved air and water pressure in the disc increases, driving the piston, connecting rod, and crankshaft assembly to rotate the second gear. The spiral chute pushes the slider outward, increasing the distance between the curved plates and forcing the impurities out. After the impurities are discharged, the torsion spring drive mechanism resets and the curved plates reclose, achieving automatic clearing of the discharge outlet, avoiding treatment interruptions caused by blockage and improving equipment operational stability and processing efficiency.

[0014] 3. Integrated design improves treatment efficiency: The integrated design of the reaction chamber and flotation tank, combined with the first and second agitators to fully stir the flocculant and coagulant aid, ensures sufficient flocculation reaction in the sewage pretreatment stage; the scraper automatically pushes the floating suspended matter into the scum tank, realizing automated operation of solid-liquid separation, reducing manual intervention and improving overall treatment efficiency.

[0015] 4. Strong adaptability and wide application range: The equipment can flexibly adjust operating parameters according to different water quality conditions (such as suspended solids concentration). Through the synergistic effect of the baffle angle and the release component, it can adapt to the treatment needs of various printing and dyeing wastewater. It has strong adaptability to working conditions and broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The gas and liquid are mixed to form dissolved air water. A scraper 10 is installed horizontally on the top of the inner cavity of the sewage treatment tank 1. The scraper 10 moves from left to right on the sewage surface to push the suspended matter into the scum trough 7.

[0020] As a preferred embodiment, further, the dissolved air water release mechanism 6 includes a frame 61 installed on the inner wall of the flotation tank 5, with a base 62 installed at the center of the frame 61. Several rotating shafts 63 are evenly installed on the inner cavity of the base 62 from left to right through bearings, and a first gear 64 is installed at the center of the outer wall of the rotating shaft 63. Baffles 65 are installed on both ends of the rotating shaft 63. The baffles 65 block the sewage and microbubbles, delay the flow of sewage, and allow a large number of microbubbles to adhere to the surface of the suspended matter. An angle adjustment component 66 is installed at the top of the inner cavity of the base 62. The angle adjustment component 66 controls the rotation of the first gear 64, thereby changing the inclination angle of the baffle 65. A mounting pipe 67 is vertically installed on the rear side of the base 62, and the top of the mounting pipe 67 is connected to the liquid outlet of the dissolved air tank 8 through a pipe to release high-pressure dissolved air into the mounting pipe 67.

Insertion rods 666 plugged into the guide grooves 663 are installed on both sides of the rack 665.

[0022] like Figure 3 and Figure 4 As shown, when screw 661 is rotated clockwise, guide plate 662 moves downward along the axis of screw 661. The rear bevel of guide slot 663 pushes rod 666 backward, driving rack 665 to slide backward along guide rail 664. Rack 665 drives first gear 64 to rotate clockwise, causing baffle 65 to tilt rightward, increasing the angle with the water flow direction, enhancing the water blocking effect, and reducing the sewage flow rate. When screw 661 is rotated counterclockwise, guide plate 662 moves upward, the front bevel of guide slot 663 pulls rod 666 forward, rack 665 slides forward, and first gear 64 rotates counterclockwise, causing baffle 65 to tilt leftward (decreasing the angle with the water flow direction), weakening the water blocking effect, and accelerating the sewage flow rate.

[0023] As a preferred solution, further, the release assembly 68 includes a joint 681 installed at the bottom of the mounting tube 67, a hollow disc 682 is installed on the top of the joint 681, one end of a driving unit 683 is installed on the lower surface of the disc 682, and the other end of the driving unit 683 is fixedly connected to the side wall of the joint 681, a second gear 684 capable of rotating is installed in the inner cavity of the disc 682, and the second gear 684 is driven to rotate by the driving unit 683, and a slide groove 685 is provided on the upper surface of the second gear 684, and the slide groove 685 is spirally opened on the upper surface of the second gear 684. When the second gear 684 is clockwise, the second gear 684 is rotated. When rotating clockwise or counterclockwise, the curved surface of the slide 685 can squeeze the teeth 688 inward or outward, allowing the slider 687 to drive the arc plate 689 gradually closer or farther away. Sealing rings 686 are installed on the inner wall of the disc 682 at equal intervals along the circumference, and several sliders 687 are inserted into the inner wall of the disc 682 at equal intervals along the circumference. The sealing rings 686 are used to seal the disc 682 and the slider 687. The bottom of the slider 687 is equipped with teeth 688 that are inserted into the inner cavity of the slide 685, and an arc plate 689 is installed on the inner side of the slider 687. The arc plates 689 are combined to form a circular through cavity, which serves as a liquid outlet for releasing dissolved gas and water.

[0024] As a preferred solution, further, the driving unit 683 includes a piston cylinder 6831 installed laterally on the side wall of the joint 681, and a piston 6832 that can slide left and right is inserted into the inner cavity of the piston cylinder 6831. The right end of the piston 6832 is connected to one end of the connecting rod 6833 through a pin. A connecting pipe 6834 is installed between the outer wall of the piston cylinder 6831 and the bottom of the disc 682. A rotatable crankshaft 6835 is installed in the inner cavity of the connecting pipe 6834. The bottom of the crankshaft 6835 is connected to the other end of the connecting rod 6833 through a pin. A third gear 6836 that is meshed with the second gear 684 is installed on the top of the crankshaft 6835. A torsion spring 6837 is sleeved on the outer wall of the crankshaft 6835, and the two ends of the torsion spring 6837 are respectively clamped with the crankshaft 6835 and the inner wall of the piston cylinder 6831. Under the action of the torsion force of the torsion spring 6837, the crankshaft 6835 is driven to rotate, and the torsion force of the torsion spring 6837 is used to resist the pressure of the dissolved air and water.

[0025] As a preferred solution, further, the connecting rod 6833 is installed at an eccentric position of the crankshaft 6835, so that the right end of the connecting rod 6833 performs circular motion, while the left end of the connecting rod 6833 performs linear motion, thereby realizing the linkage between the piston 6832 and the crankshaft 6835.

[0026] like Figure 5 、 Figure 6 and Figure 7As shown, the high-pressure dissolved air in the dissolved air tank 8 flows into the disc 682 through the installation pipe 67 and releases microbubbles through the gaps in the curved plate 689. When the release port is blocked by suspended impurities, the pressure in the disc 682 increases, pushing the piston 6832 (located in the piston cylinder 6831 of the drive unit 683) to the right. The crankshaft 6835 is driven to rotate via the connecting rod 6833. The third gear 6836 at the top of the crankshaft 6835 drives the second gear 684 to rotate. The spiral chute 685 pushes the slider 687 outward through the teeth 688, increasing the distance between the curved plates 689 and forcing the impurities to be discharged. After the impurities are discharged, the torsion spring 6837 drives the crankshaft 6835 to return to its original position, and the curved plate 689 is closed again, achieving automatic unblocking of the release port.

[0027] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific work is as follows.

[0028] In step 1, the sewage first enters the reaction chamber 2 and is stirred by the first stirrer 3 and the second stirrer 4, so that the flocculant and the coagulant aid are fully in contact with the sewage, thereby achieving a sewage flocculation reaction. Then, the sewage flows from the bottom of the reaction chamber 2 into the flotation tank 5. Under the suction of the water pump 9, high-pressure water is input into the air dissolving tank 8, and high-pressure gas is input into the air dissolving tank 8. The gas and liquid mix to form dissolved air water, which is input into the installation pipe 67 through a pipeline. The dissolved air water passes through the joint 681 and the disc 682 in sequence and is discharged from the discharge port formed by the arc plate 689. Microbubbles adhere to the surface of the suspended matter, increasing the buoyancy of the suspended matter. The sewage moves from left to right in the sewage treatment tank 1. The sprocket on the scraper 10 pulls the chain to move, causing the scraper to move from left to right. The scraper pushes the suspended matter on the sewage surface into the scum tank 7, completing the solid-liquid separation of the sewage. Step 2: Adjust the baffle 65 according to the amount of suspended matter in the sewage. Rotate the screw 661 clockwise or counterclockwise to raise or lower the guide plate 662. The inclined surface of the guide groove 663 presses the insertion rod 666 forward or backward, causing the rack 665 to move back and forth along the outer wall of the guide rail 664. Under the transmission condition of the rack 665 and the first gear 64, the inclination angle of the baffle 65 is changed to control the rising rate of the suspended matter and microbubbles in the sewage. Therefore, flotation can be performed according to the concentration of suspended matter in the sewage, allowing the suspended matter to float fully and completely remove the solids in the sewage. Step 3: Once the discharge port formed by the curved plate 689 is clogged with impurities, the dissolved air pressure inside the disc 682 increases, causing the piston 6832 to move rightward along the piston cylinder 6831. This causes the connecting rod 6833 to pull the crankshaft 6835 to rotate, and the third gear 6836 to drive the second gear 684 to rotate. The inclined surface of the chute 685 presses the teeth 665 outward, allowing the slider 687 to drive the curved plate 689 to gradually separate, thereby discharging the blocked impurities. After the gap between the arc-shaped plates 689 is unblocked, the pressure inside the disc 682 drops, the torsion force of the torsion spring 6837 drives the crankshaft 6835 to rotate, and the connecting rod 6833 pulls the piston 6832 to the left to return to the initial position. The curved surface of the slide 685 squeezes the teeth 688 inward, and the arc-shaped plates 689 move inward until they contact each other. Therefore, it has an anti-clogging function and realizes continuous treatment of sewage.
