Description

Technical Field

[0001] This invention relates to an urban sewage treatment device, specifically a device capable of treating urban sewage, belonging to the field of sewage treatment. In particular, it relates to a sewage treatment device that uses a connecting rod to separate rising air bubbles in sewage, and simultaneously uses fan blades to rotate and disperse the bubbles, thereby enhancing the aeration effect. Background Technology

[0002] Currently, some cities have inadequate drainage systems, which can easily lead to waterlogging during heavy rain or continuous rainfall. In the treatment of urban sewage, aeration devices are often used to enhance the contact between air and water, dissolving oxygen from the air into the water and releasing gases and volatile substances from the water into the air. Existing aeration devices use air pumps to aerate the sewage, which has low aeration efficiency and slow speed, and cannot quickly disperse the gases and volatile substances inside the sewage into the air.

[0003] CN207330530U discloses a float-type sewage aeration device, characterized by comprising a float, a frame mounted on the float, a motor, a main reducer connected to the motor output, a transmission device, and multiple impellers distributed circumferentially around the float. The motor and main reducer are mounted on the frame, which extends horizontally outward to form multiple support arms. The impellers are pivotally mounted on the support arms. The transmission device includes a driving pulley, a number of driven pulleys equal to the number of impellers, and a belt. The driving pulley is coaxially connected to the output of the main reducer, and each impeller is coaxially connected to a driven pulley. The driving pulley is connected to each driven pulley via a belt. This device aerates sewage by stirring it with impellers, but it cannot oxygenate the sewage internally, thus failing to ensure sufficient contact between the sewage and air. The aeration efficiency is low and the speed is slow.

[0004] CN206692428U discloses a wastewater aeration device that combines blower and mechanical aeration, including a buoyancy cylinder, a connecting cylinder, a connecting rod, a fixing block, a motor fixing block, a motor, a protective rod, a fan blade, a rotating shaft, an aeration head, an aeration pipe, a thin pipe, a support rib, a fixing column, a fan blade support column, and a coupling. This device uses the fan blade to break up rising air bubbles for secondary aeration of wastewater. However, when the fan blade rotates, air bubbles can easily pass through the gaps, affecting the aeration effect and failing to effectively disperse the air bubbles to enhance the aeration effect of the wastewater.

The fan blade (8), stiffening rib, circular retaining plate (10), connecting rod (11), second support rod (12), gear (13), turntable (14), nail head (18) and through hole (19) are composed of a fan blade (8), stiffening rib, circular retaining plate (10), connecting rod (11), second support rod (12), gear (13), turntable (14), nail head (18) and through hole (19). One end of the first support rod (2) is placed on the connecting plate (16), and the turntable (14) is placed on the other end of the first support rod (2). The first support rod (2) is a cylindrical structure with the other end open. A retaining ring is placed inside the first support rod (2). One end of the second support rod (12) is placed inside the first support rod (2). A retaining groove is opened on one end of the second support rod (12). The retaining groove and the retaining ring are correspondingly engaged. Circular retaining plate (10) is placed on the second support rod (12). Multiple gears (13) are placed on the circular retaining plate (10). On the gear (13) and the turntable (14), the gear (13) and the fixed seat (1) are correspondingly meshed. One end of the connecting rod (11) is placed on the gear (13), and the other end of the connecting rod (11) extends to the fixed seat (1). A bearing (7) is placed between the connecting rod (11) and the fixed seat (1). A fan blade (8) is placed on the connecting rod (11), and bearings (7) are placed at both ends of the fan blade (8). Multiple reinforcing ribs (20) are placed at equal angles on the other end of the second support rod (12). One end of the reinforcing rib (20) is connected to the second support rod (12), and the other end of the reinforcing rib (20) extends to the fixed ring (21). The connecting rod (11) is a slender rod.The fan blade (8) has a spindle-shaped structure.

[0021] When in use, the sewage treatment device is placed in the aeration tank. The float plate (3) floats on the surface of the liquid in the aeration tank. The air pump (5) and the drive motor (4) are started. The air pump (5) inputs outside air into the main body through the air inlet pipe (6) and fills the first support rod (2) through the through hole, thereby pumping air into the sewage and enhancing the aeration effect. At the same time, the motor shaft of the drive motor (4) drives the first support rod (2) to rotate. The first support rod (2) adjusts the turntable (14) to rotate. The turntable (14) and the gear (13) mesh, thereby causing the gear (13) to rotate, which in turn causes the connecting rod (11) to drive the fan blade (8) to rotate, breaking up the gas in the aeration tank and making the aeration more complete.

[0022] Example 2

[0023] The difference between this embodiment and embodiment 1 is that: a nail head (18) is placed on the other end of the second support rod (12), and multiple through holes (19) are opened on the nail head (18); when in use, the axis of the nail head (18) is kept in the center of the device, which can enhance the overall weight of the device, thereby improving the stability of the device and preventing the floating plate (3) from shaking under the impact of the air bubbles;

[0024] The connecting rod (11) is designed with a fan blade (8). When in use, the gear (13) drives the connecting rod (11) to rotate. The connecting rod (11) cuts the floating foam and drives the fan blade (8) to rotate. The fan blade (8) rotates and continuously beats the air bubbles in the sewage, breaking up the air bubbles and making the sewage tank fully aerated.

[0025] The fan blade (8) is designed with a spindle-shaped structure. The spindle-shaped structure has a smooth and regular surface. When the fan blade (8) turns over in the sewage, it mainly exhibits laminar flow, which ensures that the fan blade (8) is subjected to less resistance, thereby enabling the fan blade (8) to form irregular turning to break up the bubbles.

[0026] The connecting rod (11) is designed as a slender rod, which makes the diameter of the connecting rod (11) small, so that the cross-section of the connecting rod (11) is close to a linear structure. When the connecting rod (11) rotates, it can quickly cut and break up the bubbles.

[0027] The fan blade (8) is designed with bearings (7) at both ends. When the connecting rod (11) rotates, the fan blade (8) is resisted by the sewage and thus flips over, so that the fan blade (8) and the connecting rod (11) form a relative rotation. The irregular flipping and rotation of the fan blade (8) cuts and breaks up the air bubbles, thus making the aeration more complete.

[0028] The design of the bottom of the float plate (3) is equipped with an air bladder, which can help increase the buoyancy of the float plate (3) so that the float plate (3) floats stably on the surface of the sewage tank and avoids the float plate (3) from overturning under the impact of air bubbles.

[0029] Since the connecting rod (11) is a slender rod, and during the rotation process, the fan blade (8) on the connecting rod (11) is subjected to resistance and transmits the resistance to the connecting rod (11), causing the connecting rod (11) to flip and shift, thereby causing the fixed ring (21) to shift. In this invention, multiple reinforcing ribs (20) are placed at equal angles on the other end of the second support rod (12), which can increase the connection stability between the second support rod (12) and the fixed ring (21), so that the fixed ring (21) will not shift under the influence of the connecting rod (11);

[0030] The design of the drive motor (4), the first support rod (2) and the connecting rod (11) is such that when in use, the drive motor (4) drives the first support rod (2) to rotate, and the turntable (14) and gear (13) on the first support rod (2) mesh to form a transmission relationship, so that the turntable (14) drives the gear (13) to rotate, and then the connecting rod (11) rotates. At the same time, the first support rod (2) has an internal hollow structure. With the help of the air pump (5), air is input into the first support rod (2) through the air inlet pipe (6). The air enters the aeration tank for aeration, and the connecting rod (11) disperses the bubbles to make the aeration more complete.

[0031] This achieves the purpose of breaking down and rotating the rising air bubbles in the wastewater, thereby enhancing the aeration effect.
