[0002] High-efficiency shallow flotation water purification and treatment equipment adopts the dissolved air flotation principle. Part of the dissolved air water is introduced into the pool containing the water to be treated. The tiny bubbles released from the dissolved air water are used to float the suspended matter or oil in the water to the surface, thereby achieving the purpose of solid-liquid separation. The scum on the surface of the pool is then collected by a scum collecting device. The scum collecting device includes an inclined sludge hopper, which rotates along the circumference of the pool. The sludge hopper rotates along the circumference of the pool and rotates on its own while rotating. The sludge floating on the water surface is scooped into the sludge hopper. The sludge slides to the middle of the pool and enters the sludge storage tank.

The scum entering the collecting pipe flows to the middle position of the tank body and then enters the sludge storage tank. When the collecting pipe drives the collecting hopper to rotate along the circumference of the collecting pipe, the collecting hopper moves on the water surface, which will push the scum on the water surface to move and disperse, reducing the scum scooped out by the sludge hopper and affecting the efficiency of scum collection.

DETAILED DESCRIPTION

[0018] The embodiment of the present application discloses a highly efficient shallow-layer air-floating water purification treatment equipment, wherein an auxiliary collecting assembly 3 is arranged in the pool body 1 and rotates along the circumference of the pool body 1 following the sludge hopper 21. The auxiliary collecting assembly 3 includes: a baffle 31, which is used to hinder the movement of scum and make the scum within the rotation range of the sludge hopper 21; a support plate 32, the lower surface of the support plate 32 is close to the side of the baffle 31 and is fixedly connected to the top of the baffle 31; a scraper 33, which is slidably fitted with the upper surface of the support plate 32; a driving member 34, which drives the scraper 33 to reciprocate along the short side direction of the support plate 32, thereby blocking the scum within the scooping range of the collecting hopper 212, and improving the cleaning efficiency of the scum to a certain extent.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-Figure 3A high-efficiency shallow air flotation water purification treatment equipment includes a scum collecting device 2 installed in a pool body 1 to collect scum. The scum collecting device 2 includes a sludge hopper 21 rotating along the circumference of the pool body 1. The sludge hopper 21 includes a collecting pipe 211. A plurality of collecting hoppers 212 are arranged at intervals on the collecting pipe 211. The interiors of the plurality of collecting hoppers 212 are connected to the interior of the collecting pipe 211. The end of the collecting pipe 211 near the edge of the pool body 1 is higher than the end near the middle of the pool body 1. After the scum enters the collecting pipe 211, it slides to the middle of the pool body 1 and then enters the sludge storage tank. A clear water tank 5 for circulating water supply is reserved at the center of the pool body 1. An auxiliary collecting assembly 3 is arranged in the pool body 1 to rotate along the circumference of the pool body 1 following the sludge hopper 21. The auxiliary collecting assembly 3 includes a baffle 31. The baffle 31 is fixedly installed on the scum. On the collecting device 2, the baffle 31 follows the sludge hopper 21 to rotate circumferentially along the tank body 1. Part of the baffle 31 is below the water surface, and part of the baffle 31 is above the water surface. The collecting pipe 211 drives the collecting hopper 212 to rotate. The opening of the collecting hopper 212 is first toward the water surface, and then moves at the water level line position to scoop up the scum. At this time, part of the scum is pushed by the collecting hopper 212 to move toward the baffle 31 and is blocked by the baffle 31. The collecting hopper 212 slowly moves toward the baffle 31 until it fits with the baffle 31, and the scum between the baffle 31 and the collecting pipe 211 is scooped out. As the collecting hopper 212 filled with scum continues to rotate upward, the scum in the collecting hopper 212 flows into the collecting pipe 211, and then slides from the collecting pipe 211 to the middle position of the tank body 1 and enters the sludge storage tank, which improves the cleaning efficiency of the scum to a certain extent.

[0021] Reference Figure 2-Figure 4The auxiliary collecting assembly 3 also includes a supporting plate 32, a scraper 33, a driving member 34, and a power member 37. The side of the lower surface of the supporting plate 32 close to the baffle plate 31 is fixedly connected to the top of the baffle plate 31, and a mounting plate 35 is fixedly installed at both ends of the upper surface of the supporting plate 32. The mounting plate 35 is vertically arranged with the supporting plate 32. A slide groove 351 is provided at the corresponding position of the two supporting plates 32, and a slider 36 is slidably connected in the two slide grooves 351. The two ends of the scraper 33 are respectively fixedly connected to the two sliders 36. The scraper 33 is slidably fitted with the upper surface of the supporting plate 32. A driving member 34 for driving the scraper 33 to reciprocate along the short side direction of the supporting plate 32 is provided on the supporting plate 32. The driving member 34 includes two cranks 341 and two connecting rods 342. The two cranks 341 are rotatably connected to the ends of the sludge bucket 21 on the opposite sides of the two supporting plates 32. One end of the connecting rod 342 is rotatably connected to the crank 341 at the corresponding position, and the other end of the connecting rod 342 is rotatably connected to the slider 36 at the corresponding position. The power piece 37 is used to drive the two cranks 341 to rotate at the same time. The simultaneous rotation of the two cranks 341 drives the connecting rod 342 to change its position, so that the slider 36 moves back and forth along the slide groove 351, thereby driving the scraper 33 to move back and forth along the short side direction of the support plate 32. When the scum on the water surface accumulates too thickly, the scum scooped out by the collecting hopper 212 may overflow and flow onto the support plate 32. The scraper 33 blocks the scum flowing onto the support plate 32 and pushes it toward the collecting hopper 212. The scum can re-enter the water surface between the baffle 31 and the collecting pipe 211 to wait for the next scooping, or directly enter the collecting hopper 212, slide into the middle position of the pool body 1 and then enter the sludge storage tank, thereby improving the cleaning efficiency of the scum to a certain extent.

[0022] Reference Figure 4 The power member 37 includes a connecting column 371, which is close to the end of the support plate 32 away from the sludge bucket 21. The two ends of the connecting column 371 are respectively fixedly connected to the ends of the two cranks 341 away from the connecting rod 342. A driven gear 372 is fixedly installed on the connecting column 371, and the driven gear 372 is coaxially arranged with the connecting column 371. A motor 373 is fixedly installed on the support plate 32, and a driving gear 374 is fixedly installed on the output end of the motor 373. The driving gear 374 is meshed with the driven gear 372. The rotation of the motor 373 drives the driving gear 374 to rotate, and the rotation of the driving gear 374 drives the connecting column 371 to rotate through the driven gear 372, so that the two cranks 341 rotate simultaneously.

[0023] Reference Figure 1 A splash plate 4 is fixedly installed at the end of the baffle 31 near the clean water tank 5. The splash plate 4 is located between the clean water tank 5 and the end of the collecting hopper 212 near the clean water tank 5. The splash plate 4 is located between the support plate 32 and the collecting pipe 211 to prevent the scum in the collecting hopper 212 from falling into the clean water tank 5.

[0024] The working principle of the embodiment of the present application is as follows: when the high-efficiency shallow air flotation water purification treatment equipment treats sewage, the sludge hopper 21 rotates along the circumference of the pool body 1, and the motor 373 is started to make the scraper 33 reciprocate along the short side direction of the support plate 32. At the same time, the collecting pipe 211 drives the collecting hopper 212 to rotate, and the opening of the collecting hopper 212 faces the water surface. As the collecting pipe 211 rotates, the collecting hopper 212 moves near the water level line to scoop up the scum. At this time, part of the scum is pushed by the collecting hopper 212 to move toward the baffle 31 and is blocked by the baffle 31. The collecting hopper 212 slowly moves toward the baffle 31 until it is in contact with the baffle. The plate 31 is fitted to scoop out the scum between the baffle plate 31 and the collecting pipe 211, and the scraper 33 blocks the scum that flows onto the support plate 32 and pushes it toward the collecting hopper 212. The scum can re-enter the water surface between the baffle plate 31 and the collecting pipe 211 to wait for the next scooping, or directly enter the collecting hopper 212 and flow into the collecting pipe 211 together with the scum scooped from the sludge hopper 21, and then slide from the collecting pipe 211 to the middle position of the tank body 1 and enter the sludge storage tank, thereby blocking the scum within the scooping range of the collecting hopper 212, thereby improving the cleaning efficiency of the scum to a certain extent.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
