Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an efficient shallow-layer ion air flotation device. Background Art

[0002] Shallow-layer ion air flotation is an efficient water treatment technology, mainly applied to the treatment of industrial sewage and domestic sewage. Shallow-layer ion air flotation is based on the principle of dissolved air flotation, that is, partially water dissolved with gas (dissolved air water) is introduced into the water to be treated. Using the tiny bubbles released from the dissolved air water, the suspended substances or oil in the water are floated to the water surface, so as to achieve the purpose of solid-liquid separation. These tiny bubbles are numerous and can form many short-term local pressure waves in the water, bringing the suspended particulate matters in the water to the water surface to form scum. At the same time, the bubbles themselves will also rise to the water surface, enter the bubble bottom area through the supernatant area, and then flow back to the air flotation area and enter the water again to form bubbles, forming a cyclic process;

[0003] In the process of using the existing shallow-layer ion air flotation machine, the suspended substances in the sewage can be lifted by small bubbles and floated to the water surface. However, after the sundries in the sewage gather together, their weight will change, resulting in the inability of small bubbles to lift them, and then they will precipitate at the bottom of the air flotation tank. Over time, the sundries precipitated at the bottom of the air flotation tank will adsorb on the bottom of the air flotation tank. If not cleaned in time, it will affect the sewage treatment efficiency of the air flotation machine. For this reason, we propose an efficient shallow-layer ion air flotation device. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: an efficient shallow ion air flotation device, including an air flotation tank 1 inside the guardrail.

[0036] Separation components 8, multiple separation components 8 are arranged, and multiple separation components 8 are all arranged in the corresponding exhaust pipes 5, using multiple separation components 8 to drive multiple stirring brushes 6 to rotate synchronously, driving multiple stirring brushes 6 to revolve and rotate simultaneously, and dispersing the sediments at the bottom of the air flotation tank 1, so that the sundries in the sewage float in the sewage and cannot gather and deposit.

[0037] The pneumatic component 7 includes a driving part 9 arranged in the drain pipe, using the driving part 9 to provide power for the rotation of multiple stirring brushes 6. A support part 10 is arranged below the exhaust pipe 5, using the support part 10 to support the positions of multiple stirring brushes 6.

[0038] The driving member 9 includes an auxiliary bearing 91 arranged in the exhaust pipe 5. An inner ring of the auxiliary bearing 91 is provided with a driving ring 92. A plurality of driving fan blades 93 are arranged in the driving ring 92. Driving shafts 94 are arranged at opposite ends of the plurality of driving fan blades 93. The top of the driving shaft 94 is conical. The function is that the auxiliary bearing 91 is stably installed in the exhaust pipe 5. The plurality of driving fan blades 93 in the driving ring 92 rotate under the action of air flow or water flow, thereby generating rotational power. At the same time, the conical design of the top of the driving shaft 94 also helps to guide the air flow and further improve the efficiency of power generation.

[0039] The support member 10 includes a circular pipe 101 arranged at the bottom end of the exhaust pipe 5. A plurality of exhaust grooves 102 are formed on the outer side of the circular pipe 101. A protective cover 103 is arranged at the bottom end of the circular pipe 101. The function is that the plurality of exhaust grooves 102 formed on the outer side of the circular pipe 101 can effectively guide the air flow direction after the air flow blows the driving fan blades 93 to rotate, so that the gas generated in the gas-water release system 4 directly enters the air flotation tank 1 and generates bubbles.

[0040] The separation assembly 8 includes a transmission member 11 arranged in the protective cover 103. The transmission member 11 is used to transmit power for the rotation of the plurality of stirring brushes 6. A guiding member 12 is arranged in the protective cover 103. The force that drives the transmission member 11 by the guiding member 12 can control the rotation of the plurality of stirring brushes 6. A friction reducing member 13 is arranged in the protective cover 103. The friction reducing member 13 is used to reduce the friction between components, so that the force generated by the driving fan blades 93 can be transmitted to the rotation of the stirring brushes 6. A revolution member 14 is arranged in the protective cover 103. The revolution member 14 is used to drive the plurality of stirring brushes 6 to revolve.

[0041] The transmission member 11 includes a transmission rod 111 arranged at the bottom end of the driving shaft 94. The transmission rod 111 is rotatably arranged in the protective cover 103. A transmission gear 112 is arranged at the bottom end of the transmission rod 111. The function is that the force generated by the driving fan blades 93 is transmitted to the transmission gear 112 through the transmission rod 111, driving the transmission gear 112 to rotate, and further transmitting power for the rotation of the stirring brushes 6.

[0042] The guiding member 12 includes a guiding bearing 121 arranged in the protective cover 103. An inner ring of the guiding bearing 121 is provided with a guiding plate 122. The guiding plate 122 is rotatably arranged in the protective cover 103 through the guiding bearing 121. The function is that the guiding bearing 121 is used to reduce the friction between the guiding plate 122 and the protective cover 103, so that when the transmission gear 112 drives the synchronous gear 142, the guiding plate 122 can drive the corresponding plurality of stirring brushes 6 to revolve through a plurality of tooth grooves 141 in cooperation with the synchronous gear 142.

[0043] The friction-reducing member 13 includes a plurality of friction-reducing bearings 131 disposed in the guide plate 122. The inner rings of the plurality of friction-reducing bearings 131 are each provided with a rotating shaft 132, and the plurality of rotating shafts 132 are each rotatably disposed in the guide plate 122 through the corresponding friction-reducing bearing 131. A plurality of stirring brushes 6 are respectively disposed at the bottom ends of the corresponding rotating shafts 132. Its function is to use the friction-reducing bearing 131 to reduce the frictional force between the rotating shaft 132 and the guide plate 122, so that the power generated by the driving fan blade 93 can be applied to the rotation of the stirring brush 6 as much as possible, reducing power loss.

[0044] The revolution member 14 includes a plurality of tooth grooves 141 disposed in the protective cover 103. Synchronous gears 142 are disposed on the outer sides of the plurality of rotating shafts 132, and the plurality of synchronous gears 142 are each meshed with the transmission gear 112, and the plurality of synchronous gears 142 are each meshed with the plurality of tooth grooves 141. Its function is that when the transmission gear 112 drives the synchronous gear 142 to rotate, the synchronous gear 142 can revolve through the plurality of tooth grooves 141, so that the stirring brush 6 rotates while revolving, thereby expanding the stirring area of the stirring brush 6.

[0045] During use, the sewage transfer system 2 transfers sewage into the air flotation tank 1, and the air-water release system 4 transports gas through the exhaust pipe 5 into the sewage in the air flotation tank 1, thereby generating bubbles and forming floating foam. The floating foam collection device located above the air flotation tank 1 automatically collects the floating foam on the surface of the sewage. When the air-water release system starts releasing gas, the gas passes through the exhaust pipe 5. When the gas passes through the exhaust pipe 5, the gas blows the driving fan blade 93, causing the driving fan blade 93 and the driving ring 92 to rotate. The auxiliary bearing 91 arranged on the outer side of the driving ring 92 can reduce the friction between the driving ring 92 and the inner wall of the exhaust pipe 5, enabling the driving fan blade 93 to rotate more quickly and easily. When the driving fan blade 93 rotates, the driving shafts 94 arranged at the opposite ends of the multiple fan blades will rotate together. The conical shape at the top of the driving shaft 94 can guide the gas to blow on the driving fan blade 93, thereby causing the driving fan blade 93 to rotate quickly and generate power. When the driving shaft 94 rotates, the transmission rod 111 arranged at the bottom of the driving shaft 94 will rotate together with the driving shaft 94. When the transmission rod 111 rotates, the transmission gear 112 arranged at the bottom of the transmission rod 111 will rotate together with the transmission rod 111. The rotating transmission gear 112 will drive a plurality of synchronous gears 142 meshing with it to rotate together. When the multiple synchronous gears 142 rotate simultaneously, the rotating shafts 132 at the centers of the multiple synchronous gears 142 will rotate together. The rotating rotating shafts 132 will drive the corresponding stirring brushes 6 at their bottom ends to rotate, thus forming the self-rotation of the stirring brushes 6. When the synchronous gears 142 rotate, since the synchronous gears 142 mesh with a plurality of tooth grooves 141 on the protective cover 103, the rotating synchronous gears 142 will rotate around the transmission gear 112, thereby forming a revolution. The stirring brushes 6 arranged at the bottom ends of the rotating shafts 132 will move together with the rotating shafts 132, thereby increasing the movement area of the stirring brushes 6, and thus being able to stir the sundries in the sewage more dispersedly by the stirring brushes 6. By guiding the bearing 121 to rotate, the guiding plate 122 arranged in the protective cover 103 can support the movement trajectories of the rotating shafts 132 at the centers of the multiple synchronous gears 142 when the multiple synchronous gears 142 perform a revolution, enabling the revolution of the multiple stirring brushes 6 to proceed smoothly. The anti-friction bearing 131 arranged at the top of the rotating shaft 132 can reduce the friction between the rotating shaft 132 and the guiding plate 122 when the rotating shaft 132 rotates, thereby achieving the purpose of minimizing power loss as much as possible.

[0046] Embodiment 2: Please refer to Figure 9 , the present invention provides a technical solution:

[0047] A plurality of through holes 15 are formed at the bottom of the circular pipe 101, and the directions of the plurality of through holes 15 all face the top of the protective cover 103. Its function is to guide the gas in the exhaust pipe 5 to the top of the protective cover 103, thereby preventing sundries in the sewage from accumulating on the top of the protective cover 103.
