[0014] The present invention provides an air flotation device for deep treatment of wastewater generated by colorant manufacturing. It has the following beneficial effects: (1) The invention makes the bubbles in the wastewater more evenly distributed by the rotating plate, promotes the physical adsorption and separation in the flotation process, and ensures the full mixing of the bubbles and the wastewater, thereby effectively improving the flotation treatment efficiency. After the scraper is reset, it contacts the mixture of bubbles and impurities on the top of the wastewater surface and scrapes these impurities off the water surface, ensuring that the impurities can be removed in time to prevent them from settling again or being carried into the treatment system by the water flow again, resulting in water quality recovery or secondary pollution. At the same time, it avoids the blockage of the device or the excessive thickness of the sediment layer caused by excessive accumulation of impurities, thereby maintaining the long-term efficient operation of the flotation equipment.

[0015] (2) The invention ensures that the bubble generation system remains unobstructed by moving the scraper rod 1 to clean the air pipe, so that the bubbles in the water are evenly distributed, thereby improving the treatment efficiency. At the same time, it prevents the air pipe from being blocked and causing the bubbles to aggregate into larger bubbles. By moving the scraper rod 2 to scrape at the bottom of the box, it prevents the sludge and sediment from depositing and accumulating, ensuring that the sludge can be removed or collected in time, avoiding equipment blockage or unstable operation due to excessive deposition. At the same time, it prevents mud and suspended matter from accumulating at the bottom of the flotation device for a long time, causing equipment blockage, which may increase corrosion and wear of the equipment, thereby increasing the cost of maintenance and cleaning.

[0016] (3) The invention pushes the impurities cleaned from the surface of the wastewater by the scraper rod 1 outward by moving the push plate, ensuring that the impurities are concentrated in one area, making them easier to dehydrate and remove. This helps to reduce the retention time of impurities in the pool, thereby improving the overall treatment efficiency and reducing the treatment difficulties caused by uneven distribution of impurities. The flap is rotated to block impurities or spilled wastewater from above during the movement of the push plate, ensuring that no impurities fall into the working area of ​​the push plate when the push plate moves, thereby improving the processing capacity of the equipment and preventing impurities from falling between the push plates, causing the push plate to work abnormally, jamming or being damaged. The scraper rod 3 moves to scrape away impurities that may fall on the flap, ensuring that the flap can rotate and reset normally, preventing impurities from falling and accumulating, causing the flap to work abnormally or be damaged.

[0022] When the present embodiment is working, first, before introducing the wastewater, the staff shall check whether the equipment state is normal. After the inspection, the connecting piece shall be connected with the water outlet 5, and then the wastewater shall be introduced into the box body 1 through the water inlet 4. When the wastewater is about to be flush with the partition 6, the introduction of wastewater shall be stopped. At this time, the staff shall start the gas tank 2 to allow the gas to enter the box body 1 from the gas pipe 3 and contact the wastewater, and the impurities in the wastewater are driven to float through the bubbles to facilitate the treatment of these impurities.

The fixed rod 192 moves to drive the scraper rod 191 to start moving. The scraper rod 191 moves to clean the air pipe 3 to ensure that the bubble generation system remains unobstructed, so that the bubbles in the water are evenly distributed, and the processing efficiency is improved. At the same time, the air pipe 3 is prevented from being blocked and causing the bubbles to gather into larger bubbles. When the scraper rod 191 moves, the inclined rod 193 is driven to start moving. The inclined rod 193 moves to contact and push the inclined block 197 to start moving. The inclined block 197 moves to push the connecting rod 196 to start moving. The connecting rod 196 moves to push the scraper rod 2 195 to start moving.

[0030] As the scraper rod 195 moves, the push rod 198 is driven to start moving, and the movement of the push rod 198 drives the push plate 201 to start moving. The movement of the push plate 201 pushes the impurities cleaned from the surface of the wastewater by the scraper rod 191 outward, ensuring that the impurities are concentrated in one area, making it easier to dehydrate and remove them, which helps to reduce the retention time of impurities in the pool, thereby improving the overall treatment efficiency and reducing the treatment difficulties caused by uneven distribution of impurities. As the push plate 201 moves, the long rod 203 is no longer pushed, and then the inclined plane block 202 starts to move and reset under the action of the spring 2. The inclined plane block 202 moves and drives the flap 204 to start rotating. The flap 204 rotates to block impurities or spilled wastewater that may fall from above during the movement of the push plate 201, ensuring that no impurities fall into the working area of ​​the push plate 201 when the push plate 201 moves, thereby improving the equipment treatment efficiency.

When the push plate 201 moves, it drives the fixed rod 207 to start moving. The movement of the fixed rod 207 drives the transmission belt 3 206 to start rotating. The rotation of the transmission belt 3 206 drives the scraper rod 3 208 to start moving. The scraper rod 3 208 moves and contacts the flap 204. After the flap 204 blocks the impurities, the push plate 201 starts to move and reset under the drive of the push rod 198. The movement of the push plate 201 drives the fixed rod 207 to move.
