Description

Technical Field

[0001] The present invention relates to the technical field of air flotation machines, and particularly to an energy-saving and environmentally friendly sewage treatment device. Background Art

[0002] There are various types of energy-saving and environmentally friendly sewage treatment devices, including chain air flotation machines. A chain air flotation machine is a sewage treatment equipment that combines air flotation technology with a chain drive system. Its core function is to achieve efficient separation of pollutants through the synergistic effect of microbubbles and the chain.

[0003] The chain air flotation machine adheres suspended solids, oils and other pollutants in the sewage to the surface of microbubbles through high-speed air flow, forming a scum layer with a density less than that of water. At the same time, the chain drive system is responsible for transporting and collecting the scum. And in the scum scraping process, the chain cooperates with the scraper to continuously scrape the scum into the sludge tank to achieve solid-liquid separation.

[0004] However, in the actual application process, we observed that when the scraper of the existing chain air flotation machine performs the function of scraping scum, there are significant problems: a large amount of scum will remain on the scraper itself. Although these residues can be partially removed in the subsequent scum scraping process, the residue phenomenon continues to occur, forming a cyclic process. This not only weakens the overall scum scraping efficiency but also exposes the limitations of the scraper function. It can only remove the scum on the upper surface. When faced with a large amount of scum accumulation, the scraping ability of the scraper seems inadequate and it is difficult to quickly and effectively complete the work, thus triggering a series of chain reactions. For this reason, we propose an energy-saving and environmentally friendly sewage treatment device. Summary of the Invention

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Embodiment 1: Please refer to Figures 1-11 , the present invention provides a technical solution: an energy-saving and environmentally friendly sewage treatment device, including a body 1, a support frame 4, two chains 2 and two driving rods 3. The chains 2 and the driving rods 3 are both prior arts and will not be elaborated here. It further includes:

[0043] A moving groove plate 7, arranged between the two chains 2;

[0044] A telescopic plate 8, movably arranged on the inner wall of the moving groove plate 7, extending when performing slag scraping work and retracting otherwise;

[0045] A rotating bottom plate 9, rotatably arranged at the bottom of the telescopic plate 8;

[0046] The rotating deformation unit 5 is arranged on the machine body 1 and is used for driving the telescopic plate 8 to extend from the inner wall of the moving groove plate 7 when scraping slag, and also driving the rotating bottom plate 9 to rotate at the bottom of the telescopic plate 8, so that the moving groove plate 7, the telescopic plate 8 and the rotating bottom plate 9 form an L shape when scraping slag. After the three form an L shape, there will be a slot at the moving groove plate 7, which can reduce a certain resistance, and the floating slag inside will fall and be flushed after reversing;

[0047] The arc-shaped plate 11 is movably arranged inside the machine body 1 and is in movable contact with the side of the moving groove plate 7;

[0048] The flushing assembly 6 is arranged on the machine body 1 and is used for spraying water on the moving groove plate 7, the telescopic plate 8 and the rotating bottom plate 9 to clean them when the moving groove plate 7 contacts the arc-shaped plate 11;

[0049] The scraper 10 is arranged on the side of the telescopic plate 8, and there are multiple scrapers 10, which are used for scraping the floating slag on the moving groove plate 7 when the telescopic plate 8 retracts.

[0050] The rotating deformation unit 5 includes two side plates 51 fixedly arranged on both sides of the inner wall of the machine body 1. Inner ring grooves 514 are opened on the adjacent inner sides of the two side plates 51. The driving rod 3 sequentially penetrates through the sides of the two side plates 51. Two moving rollers 52 are movably arranged inside the two inner ring grooves 514. The four moving rollers 52 are divided into two groups and are respectively rotatably arranged on both sides of the corresponding moving groove plate 7. By arranging the inner ring grooves 514, the moving rollers 52 can be moved, so as to drive the moving groove plate 7 to move along a fixed route and prevent deviation.

[0051] Adjusting rollers 53 are arranged on both sides of the telescopic plate 8. Straight grooves 54 are opened on both sides of the moving groove plate 7. The two adjusting rollers 53 are movably arranged on the inner walls of the corresponding straight grooves 54. A plurality of C-shaped plates 55 are arranged on both sides of the moving groove plate 7. The plurality of C-shaped plates 55 are movably arranged on the outer surface of the telescopic plate 8;

[0052] An outer ring groove 515 is opened on the side of the side plate 51 close to the moving groove plate 7, and inclined grooves 517 are opened at both ends of the outer ring groove 515. A deformation groove 516 is opened between the adjacent end faces of the two inclined grooves 517. The outer ring groove 515, the two inclined grooves 517 and the deformation groove 516 are communicated with each other. The adjusting roller 53 is movably arranged on the inner walls of the outer ring groove 515, the two inclined grooves 517 and the deformation groove 516. By setting the movement track of the moving groove plate 7 at the inner ring groove 514, at this time, the adjusting roller 53 connected to the telescopic plate 8 changes, so that it enters the deformation groove 516 when scraping slag, so as to extend and lengthen.

[0053] A protective shell 56 is provided at the bottom of the movable slot plate 7. A chute 57 is provided on the side of the protective shell 56. A slide bar 512 is rotatably provided on the side of the rotating bottom plate 9. The slide bar 512 is movably arranged on the inner wall of the chute 57. A connecting ring 511 is provided at the end face of the slide bar 512. A second torsion spring 513 is sleeved on the outer surface of the slide bar 512. One end of the second torsion spring 513 is provided at the end face of the connecting ring 511. A winding ring 58 is rotatably provided inside the protective shell 56. A first torsion spring 510 is provided on the inner wall of the winding ring 58. One end of the first torsion spring 510 is provided on the inner wall of the protective shell 56. A hanging rope 59 is wound on the outer surface of the winding ring 58. The other end of the hanging rope 59 is fixedly wound on the connecting ring 511. By using the fixity of the movable slot plate 7, when the telescopic plate 8 moves, the winding ring 58 winds up the hanging rope 59, thereby driving the connection to rotate, and thus driving the rotating bottom plate 9 to rotate.

[0054] The flushing assembly 6 includes two first springs 68 provided on the side of the arc plate 11. An arc-shaped groove 63 is provided on the side of the side plate 51. The arc plate 11 is movably arranged on the inner wall of the arc-shaped groove 63. A guide rod 67 is provided on the side of the arc plate 11. One end of the guide rod 67 away from the arc plate 11 penetrates the inner wall of the arc-shaped groove 63. A driving plate 610 is provided at the end of the guide rod 67 penetrating the inner wall of the arc-shaped groove 63. The driving plate 610 is movably sleeved on the driving rod 3. Both sides of the movable slot plate 7 are inclined surfaces. In this way, when it contacts the arc plate 11, it can squeeze the arc plate 11, so that the arc plate 11 drives the guide rod 67 to move, thereby driving the driving plate 610 to move.

[0055] A first gear ring 611 is rotatably provided on the side of the driving plate 610. A first spline sleeve 612 is provided on the inner wall of the first gear ring 611. A first spline shaft 69 is sleeved on the outer surface of the driving rod 3. The first spline sleeve 612 is movably arranged on the outer surface of the first spline shaft 69. A second gear ring 613 is rotatably provided on the side of the driving plate 610 close to the first gear ring 611. The second gear ring 613 and the first gear ring 611 are meshed with each other. A second spline sleeve 618 is provided on the inner wall of the second gear ring 613. A second spline shaft 614 is rotatably provided on the side of the side plate 51. The second gear ring 613 is movably sleeved on the outer surface of the second spline shaft 614. The first gear ring 611 and the second gear ring 613 are meshed with each other and are simultaneously rotatably provided on the side of the driving plate 610. Therefore, when the guide rod 67 is pushed, they will move together. The starting position of the first spline sleeve 612 does not enter the outer surface of the first spline shaft 69. They are only connected together when the guide rod 67 moves. However, the second spline sleeve 618 and the second spline shaft 614 are always in a connected state.

[0056] On the end face of the spline shaft two 614 away from the side plate 51, there is a crankshaft 619. On the end face of the crankshaft 619, there is a fixing plate 615. A rotating plate 623 is movably sleeved on the outer surface of the crankshaft 619. A lifting rod 621 is rotatably arranged on the side of the rotating plate 623. A guiding plate 620 is movably sleeved on the outer surface of the lifting rod 621. The side of the guiding plate 620 is fixedly arranged on the side of the fixing plate 615. By rotating the crankshaft 619, the rotating plate 623 can be driven to move, thereby driving the lifting rod 621 to move. Since the lifting rod 621 is limited by the guiding plate 620, the movement trajectory of the lifting rod 621 is only up and down movement.

[0057] At the top of the lifting rod 621, there is a piston disc 622. On the side of the side plate 51, there is a placing plate 617. Inside the placing plate 617, there is an air cylinder 616. The piston disc 622 is movably arranged on the inner wall of the air cylinder 616. On the side of the air cylinder 616, there is a water suction pipe 61. The other end of the water suction pipe 61 is arranged inside the machine body 1. And at the top of the air cylinder 616, there is a connecting pipe 65 that is interconnected with the inside. By driving the piston disc 622 to move back and forth in the air cylinder 616, clean water can be pumped out through the water suction pipe 61 and then discharged through the connecting pipe 65. And a check valve is arranged at the water suction pipe 61, so that the water can only be discharged from the connecting pipe 65 when pushing the water flow. When pulling the piston disc 622, the check valve will be opened. Similarly, there is also a check valve with a reverse working principle at the connecting pipe 65.

[0058] On the top of the side plate 51, there is a support plate 64. On the side of the support plate 64, there is a straight pipe 62. The top of the connecting pipe 65 penetrates through the side of the support plate 64 and extends into the inside of the straight pipe 62. On the outer surface of the straight pipe 62, there are multiple spray nozzles 66. Multiple spray nozzles 66 are all interconnected with the inside of the straight pipe 62. The water flow sprays out through the spray nozzles 66 to wash the outer surfaces of the moving groove plate 7, the telescopic plate 8 and the rotating bottom plate 9.

[0059] When using this device, first drive the chain 2 by the driving rod 3. The chain 2 will drive the moving groove plate 7 to move. The moving rollers 52 on both sides of the moving groove plate 7 will slide inside the inner ring groove 514. At this time, the adjusting roller 53 on the side of the telescopic plate 8 will slide inside the outer ring groove 515. Then when the adjusting roller 53 enters the inclined groove 517 from the outer ring groove 515, since the moving groove plate 7 is limited by the inner ring groove 514, the telescopic plate 8 will extend out from the inside of the moving groove plate 7 until it reaches the deformation groove 516 and completes the deformation. While the telescopic plate 8 extends, since the first torsion spring 510 and the winding ring 58 are both arranged on the protective shell 56, and the protective shell 56 is arranged on the moving groove plate 7, when the telescopic plate 8 moves, it will drive the rotating bottom plate 9 to move. At this time, the sliding rod 512 and the connecting ring 511 are both on the rotating bottom plate 9. Therefore, under the pulling of the hanging rope 59, the rotating bottom plate 9 rotates and forms a 90-degree angle, and the second torsion spring 513 and the first torsion spring 510 will reset when the adjusting roller 53 reaches the next inclined groove 517. Then the moving groove plate 7, the telescopic plate 8 and the rotating bottom plate 9 form an L shape for slag scraping;

[0060] After the slag scraping is completed, start to flip. At this time, the side of the moving groove plate 7 presses against the arc-shaped plate 11. The arc-shaped plate 11 will press the first spring 68 and the guide rod 67. The guide rod 67 will drive the driving plate 610. The driving plate 610 drives the first gear ring 611 and the second gear ring 613 to move. The first gear ring 611 will drive the spline sleeve one 612 to enter the outer surface of the spline shaft one 69. Since the spline shaft one 69 is arranged on the driving rod 3, when the driving rod 3 rotates, it will drive the first gear ring 611 to rotate, and the second gear ring 613 meshing with the first gear ring 611 will also rotate. The rotation of the second gear ring 613 will drive the spline sleeve two 618 to rotate. The spline sleeve two 618 will drive the spline shaft two 614 inside to rotate. The spline shaft two 614 drives the crankshaft 619 to rotate. Thus, under the limitation of the rotating plate 623, the lifting rod 621 and the guide plate 620, the piston disk 622 is driven to perform reciprocating up and down movements, so as to pump water through the water suction pipe 61 connected to the air cylinder 616. After entering the air cylinder 616, the water flow is pushed into the connecting pipe 65, enters the straight pipe 62 from the connecting pipe 65, and finally sprays out from the multiple nozzles 66 to complete the flushing.

[0061] Embodiment 2: Please refer to Figure 12 , the present invention provides a technical solution: A second spring 12 is sleeved on the outer surface of the spline sleeve one 612. The spline sleeve one 612 is movably arranged on the side of the driving plate 610, that is, the spline sleeve one 612 slides a short distance on the side of the driving plate 610. One end of the second spring 12 is arranged on the side of the driving plate 610. By providing the second spring 12, when the spline sleeve one 612 cannot be pushed onto the outer surface of the spline shaft in time, there is a buffer space to prevent the jamming phenomenon.
