Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a highly efficient shallow ion flotation device. Background Technology

[0002] Shallow ion flotation is a highly efficient water treatment technology, mainly used for the treatment of industrial and domestic sewage. Shallow ion flotation is based on the principle of dissolved air flotation, which involves introducing a portion of water containing dissolved gas (dissolved air water) into the water to be treated. The tiny bubbles released from the dissolved air water float suspended solids or oil to the surface, thereby achieving solid-liquid separation. These numerous tiny bubbles can form many brief local pressure waves in the water, bringing suspended particles to the surface and forming scum. At the same time, the bubbles themselves also rise to the surface, pass through the supernatant zone into the bubble bottom zone, and then flow back to the flotation zone to re-enter the water and form bubbles again, forming a cycle.

[0003] Existing shallow ion flotation machines can lift suspended solids in wastewater and make them float to the surface using small air bubbles. However, when the impurities in the wastewater accumulate, their weight changes, causing the small air bubbles to fail to lift them and causing them to settle at the bottom of the flotation tank. Over time, the impurities settled at the bottom of the flotation tank will adhere to the bottom of the tank. If they are not cleaned in time, it will affect the wastewater treatment efficiency of the flotation machine. To address this, we propose a highly efficient shallow ion flotation device. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-8 This invention provides a technical solution: a high-efficiency shallow ion flotation device, comprising a flotation tank 1 within a protective enclosure, wherein the flotation tank 1 is equipped with a sewage conveying system, a foam collection system 3, and an air-water release system 4, and further comprising:

[0033] Multiple exhaust pipes 5 are provided, and all multiple exhaust pipes 5 are located below the gas-water release system 4, and all multiple exhaust pipes 5 are connected to the gas-water release system 4.

[0034] Multiple stirring brushes 6 are provided, and each stirring brush 6 is located at the bottom end of the corresponding exhaust pipe 5.

[0035] Multiple pneumatic components 7 are provided, and each pneumatic component 7 is installed in a corresponding exhaust pipe 5. Power is generated by multiple pneumatic components 7 to drive the corresponding stirring brush 6 to rotate.

[0036] Multiple separation components 8 are provided, and each separation component 8 is installed in a corresponding exhaust pipe 5. Multiple separation components 8 drive multiple stirring brushes 6 to rotate synchronously. While driving the multiple stirring brushes 6 to revolve around the sun, they also rotate on their own axis, which disperses the sediment at the bottom of the flotation tank 1, so that the debris in the sewage floats in the sewage and cannot accumulate and settle.

[0037] The pneumatic assembly 7 includes a drive member 9 installed inside the drain pipe, which provides power for the rotation of multiple stirring brushes 6. A support member 10 is installed below the exhaust pipe 5 to support the position of the multiple stirring brushes 6.

[0038] The drive component 9 includes an auxiliary bearing 91 disposed within the exhaust pipe 5. A drive ring 92 is disposed within the inner ring of the auxiliary bearing 91. Multiple drive blades 93 are disposed within the drive ring 92. A drive shaft 94 is disposed at the opposite ends of the multiple drive blades 93. The top of the drive shaft 94 is conical. Its function is to ensure that the auxiliary bearing 91 is securely installed within the exhaust pipe 5, and to generate rotational power by utilizing the multiple drive blades 93 within the drive ring 92 to rotate under the action of airflow or water flow. At the same time, the conical top design of the drive shaft 94 also helps to guide the airflow, further improving the efficiency of power generation.

[0039] The support member 10 includes a circular pipe 101 located at the bottom of the exhaust pipe 5. Multiple exhaust slots 102 are provided on the outer side of the circular pipe 101, and a protective cover 103 is provided at the bottom of the circular pipe 101. The function of the multiple exhaust slots 102 located on the outer side of the circular pipe 101 is to effectively guide the airflow after the airflow is generated by the blowing drive fan blade 93. This allows the air generated in the air-water release system 4 to directly enter the flotation tank 1 and generate bubbles.

[0040] The separation assembly 8 includes a transmission component 11 disposed within a protective cover 103, which transmits power to the rotation of multiple stirring brushes 6. A guide component 12 is disposed within the protective cover 103, which drives the force of the transmission component 11 to control the rotation of multiple stirring brushes 6. A friction-reducing component 13 is disposed within the protective cover 103, which reduces friction between components and enables the force generated by the drive fan blade 93 to be transmitted to the rotation of the stirring brushes 6. A revolving component 14 is disposed within the protective cover 103, which drives the multiple stirring brushes 6 to revolve.

[0041] The transmission component 11 includes a transmission rod 111 disposed at the bottom end of the drive shaft 94, and the transmission rod 111 is rotatably disposed inside the protective cover 103. A transmission gear 112 is disposed at the bottom end of the transmission rod 111. Its function is to transmit the force generated by the drive fan blade 93 to the transmission gear 112 through the transmission rod 111, drive the transmission gear 112 to rotate, and thus transmit power to the rotation of the stirring brush 6.

[0042] The guide member 12 includes a guide bearing 121 disposed inside the protective cover 103. A guide plate 122 is disposed on the inner ring of the guide bearing 121. The guide plate 122 is rotatably disposed inside the protective cover 103 via the guide bearing 121. Its function is to reduce the friction between the guide plate 122 and the protective cover 103 by using the guide bearing 121, so that when the transmission gear 112 drives the synchronous gear 142, the guide plate 122 can drive the corresponding multiple stirring brushes 6 to revolve through multiple tooth grooves 141 in cooperation with the synchronous gear 142.

[0043] The friction-reducing component 13 includes multiple friction-reducing bearings 131 disposed within the guide plate 122. Each of the multiple friction-reducing bearings 131 has a rotating shaft 132 disposed within its inner ring, and the multiple rotating shafts 132 are rotatably disposed within the guide plate 122 via corresponding friction-reducing bearings 131. Multiple stirring brushes 6 are respectively disposed at the bottom end of corresponding rotating shafts 132. Its function is to reduce the friction between the rotating shafts 132 and the guide plate 122 by utilizing the friction-reducing bearings 131, so that the power generated by driving the fan blades 93 can be used as much as possible for the rotation of the stirring brushes 6, reducing power loss.

[0044] The revolving component 14 includes multiple toothed grooves 141 disposed within the protective cover 103. Synchronous gears 142 are disposed on the outer sides of multiple rotating shafts 132, and the multiple synchronous gears 142 mesh with the transmission gear 112. The multiple synchronous gears 142 mesh with the multiple toothed grooves 141. Its function is that when the transmission gear 112 drives the synchronous gears 142 to rotate, the synchronous gears 142 can revolve through the multiple toothed grooves 141, so that the stirring brush 6 revolves while rotating, thereby expanding the stirring area of ​​the stirring brush 6.

[0045] During operation, the sewage transfer system 2 transfers sewage to the flotation tank 1. The gas-water release system 4 delivers gas through the exhaust pipe 5 into the sewage in the flotation tank 1, generating bubbles and forming foam. The foam collection device located above the flotation tank 1 automatically collects the foam on the surface of the sewage. When the gas-water release system starts releasing gas, the gas passes through the exhaust pipe 5. As the gas passes through the exhaust pipe 5, it blows the drive fan blade 93, causing the drive fan blade 93 and drive ring 92 to rotate. The auxiliary bearing 91 located on the outside of the drive ring 92 reduces the friction between the drive ring 92 and the inner wall of the exhaust pipe 5, thus... The drive blade 93 can rotate faster and more easily. When the drive blade 93 rotates, the drive shaft 94, located at the opposite ends of the multiple blades, will rotate together. The conical shape at the top of the drive shaft 94 can guide the air to blow the drive blade 93, thereby causing the drive blade 93 to rotate quickly and generate power. When the drive shaft 94 rotates, the transmission rod 111 located at the bottom of the drive shaft 94 will rotate along with the drive shaft 94. When the transmission rod 111 rotates, the transmission gear 112 located at the bottom of the transmission rod 111 will rotate along with the transmission rod 111. The rotating transmission gear 112 will drive the gear meshing with it. Multiple synchronous gears 142 rotate together. When multiple synchronous gears 142 rotate simultaneously, the rotating shaft 132 at the center of the shaft of the multiple synchronous gears 142 will also rotate together. The rotating shaft 132 will drive the corresponding stirring brush 6 at its bottom end to rotate, thus forming the rotation of the stirring brush 6. When the synchronous gear 142 rotates, since the synchronous gear 142 meshes with the multiple tooth grooves 141 on the protective cover 103, the rotating synchronous gear 142 rotates around the transmission gear 112, thus forming a revolution. The stirring brush 6 set at the bottom end of the rotating shaft 132 will move together with the rotating shaft 132, thereby... The increased moving area of ​​the stirring brush 6 allows for more thorough dispersion of impurities in the wastewater. The guide plate 122, mounted inside the protective cover 103 and rotated via the guide bearing 121, supports the rotation trajectory of the rotating shaft 132 at the center of the multiple synchronous gears 142 during their revolution, ensuring smooth rotation of the stirring brushes 6. The friction-reducing bearing 131 at the top of the rotating shaft 132 reduces friction between the rotating shaft 132 and the guide plate 122 during its rotation, thereby minimizing power loss.

[0046] Example 2: Please refer to Figure 9 The present invention provides a technical solution:

[0047] The bottom of the round tube 101 has multiple through holes 15, and the direction of the multiple through holes 15 is towards 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 the accumulation of debris in the sewage on the top of the protective cover 103.
