Description

Technical Field

[0001] This utility model relates to the technical field of bar screen cleaning machines, specifically to a hydrodynamic adjustable speed rotary bar screen cleaning machine. Background Technology

[0002] In wastewater treatment, a rotary bar screen is used to remove impurities from the wastewater and bring them to the surface, which is a method of coarse filtration in wastewater treatment.

[0003] Chinese patent document CN207792742U discloses a hydrodynamic rotary bar screen cleaning device, including a drive motor, a main support, cleaning rake teeth, a traction chain for collecting and conveying waste, and a hydrodynamic vehicle. The drive motor is mounted on the main support and connected to a reducer. The output shaft of the reducer is connected to a drive sprocket, which is connected to a main reversing sprocket via a belt. The main reversing sprocket, driven sprocket, and auxiliary reversing sprocket are connected by a traction chain to form a longitudinal closed sprocket structure. The cleaning rake teeth are mounted on the rake tooth shaft of the main support and arranged in a certain order to form a closed rake tooth chain. A bar screen is mounted on the outside of the cleaning rake teeth. The lower part of the main support is installed in the water inlet channel and connected to pre-embedded steel plates fixed on both sides of the channel. A rubber brush is installed below the main reversing sprocket, and a waste collection and conveying device is installed below the rubber brush. A hydrodynamic vehicle is installed on the inner underwater side of the main support and is connected to the main reversing sprocket via a belt.

[0004] However, in the above scheme, the water-powered vehicle is directly installed behind the sludge rake teeth. The water-powered vehicle will be directly affected by the flow of sewage, resulting in unstable power output. This requires the drive motor to be started frequently to compensate, increasing energy consumption. Utility Model Content

[0035] Example 1

[0036] like Figure 1-3 As shown, the present invention proposes a hydrodynamic adjustable speed rotary bar screen cleaner, which includes a body 1, a connecting shaft 14, a drive assembly and a flow guiding assembly;

[0037] The connecting shaft 14 is located at the top of the body 1 and its end extends to the outside of the body 1;

[0038] The flow guiding component is located at the rear bottom of the body 1. The flow guiding component is equipped with a valve 8 for adjusting the inner cross-section of the end of the flow guiding component during use. During use, the sewage is accumulated and the flow and pressure generated by the sewage accumulation cause the sewage to be guided and discharged through the flow guiding component. The flow guiding component and valve 8 work together to reduce the sewage discharge cross-sectional area, giving the sewage a force and making the water flow velocity discharged from the flow guiding component more stable. Among them, valve 8 can be selected as a slide valve for adjusting the sewage flow cross-sectional area during use. During use, multiple valves 8 can be linked by a structure such as bevel gears, rotating shafts and motors, so that multiple valves 8 can operate synchronously and electrically.

[0039] The drive assembly is located behind the flow guiding assembly. The end of the drive assembly is provided with a transmission assembly that is connected to the body 1 and the connecting shaft 14 and transmits the rotational force of the drive assembly to the connecting shaft 14 in use. It is used to rotate by the force of the sewage during use, thereby rotating the connecting shaft 14 and making the connecting shaft 14 rotate synchronously with the drive assembly.

[0040] In this embodiment, the machine body 1 removes sewage and the flow guide component accumulates the sewage. Simultaneously, the flow guide component guides and discharges the sewage. During the discharge process, the cross-sectional area of ​​the sewage flow is gradually reduced, adjusting the sewage flow rate to be discharged towards the drive component. The sewage impacts the blades of the drive component, causing the drive component to rotate. At the same time, the connecting shaft 14 is connected to the drive component through the transmission component, causing the drive component to drive the connecting shaft 14 to rotate synchronously. The flow of sewage causes the machine body 1 to effectively intercept suspended solids in the sewage. Meanwhile, the valve 8 adjusts the inner cross-section of the end of the flow guide component, increasing the sewage flow rate in the flow guide component. This, in turn, increases the rotation speed of the connecting shaft 14 driven by the drive component, thereby increasing the operating speed of the machine body 1 and improving the overall sewage removal efficiency.

[0041] Example 2

[0042] like Figure 2 As shown, the present invention proposes a hydrodynamic adjustable speed rotary bar screen cleaner. Compared with embodiment one, the difference in this embodiment is that the flow guiding component includes a connecting shell 4, a connecting pipe 5, a flow guiding shell 6, and a conveying pipe 7.

[0043] The connecting shell 4 is installed at the bottom rear side of the body 1 and is used to seal the rear side of the body 1 during use, so that the wastewater removed by the body 1 can be accumulated.

[0044] The connecting pipe 5 is located on the rear side of the connecting shell 4 and is used to transport the sewage in the connecting shell 4 to the drive assembly.

[0045] The guide shell 6 is installed at the end of the connecting pipe 5 and communicates with the connecting pipe 5. It is used to reduce the cross-sectional area of ​​sewage flow in the connecting pipe 5 during use, so that the flow rate of sewage discharge is stable and the sewage has the impact force to drive the blades of the component.

[0046] The delivery pipe 7 is installed at the end of the guide shell 6 and connected to the valve 8, for discharging wastewater directly to the blades of the drive assembly during use.

[0047] In an optional embodiment, there are multiple connecting pipes 5, which are located at the same height on the rear side of the connecting shell 4, and are used to transport sewage to the blades of the drive assembly during use, so that the blades of the drive assembly can move circumferentially along the drive assembly, thereby generating power for the drive assembly.

[0048] In an optional embodiment, the projection shape of the connecting shell 4 is U-shaped, the bottom end of the connecting shell 4 is sealed, and the U-shaped port of the connecting shell 4 is connected to the rear side of the body 1 for accumulating the sewage from the cleaning of the body 1 during use, so that the sewage flows into the connecting pipe 5.

[0049] In an optional embodiment, the inner dimension of the guide shell 6 gradually decreases from the connecting pipe 5 to the conveying pipe 7 along the end direction of the connecting pipe 5, in order to reduce the cross-sectional area of ​​the sewage flow in the connecting pipe 5, so that the flow rate of the sewage discharged through the conveying pipe 7 is more stable, and the sewage discharged from the conveying pipe 7 impacts the blades of the drive assembly.

[0050] In this embodiment, the wastewater after cleaning the machine body 1 is intercepted by the connecting shell 4, so that the wastewater flows into multiple connecting pipes 5 under pressure, reducing the cross-sectional area of ​​the wastewater flow and ensuring that the wastewater flow velocity in each connecting pipe 5 is uniform. The wastewater flowing in the connecting pipes 5 is guided to the conveying pipe 7 by the guide shell 6. During the guiding process, the cross-sectional area of ​​the wastewater flow is further reduced, so that the wastewater directly impacts the blades of the drive component at a stable flow velocity, causing the drive component to start and perform driving work. At the same time, the cross-sectional area of ​​the inner side of the conveying pipe 7 is adjusted by the valve 8, so that the wastewater discharged from the conveying pipe 7 generates different impact forces, thereby causing the drive component to rotate at different speeds, so that the drive component drives the machine body 1 to perform different working speeds.

[0051] Example 3

[0052] like Figure 1 As shown, the present invention proposes a hydrodynamic adjustable speed rotary bar screen cleaner. Compared with embodiment one, the difference in this embodiment is that the transmission component includes a chain drive structure 2 and a speed regulating gearbox 3.

[0053] The speed regulating gearbox 3 is installed on the side of the machine body 1. Existing technologies, such as reduction gearboxes or speed increasing gearboxes, will not be described in detail here.

[0054] There are two chain drive structures 2, which are respectively installed at the top and bottom of the speed regulating gearbox 3. The ends of the two chain drive structures 2 are respectively connected to the connecting shaft 14 and the drive assembly.

[0055] In this embodiment, the two ends of the two chain drive structures 2 are respectively connected to the speed regulating gearbox 3, the connecting shaft 14 and the drive assembly, so that the drive assembly drives the speed regulating gearbox 3 to operate through one chain drive structure 2, and the speed regulating gearbox 3 drives the connecting shaft 14 to rotate through the other chain drive structure 2, thereby realizing the linkage between the drive assembly and the transmission assembly and ensuring efficient and stable power transmission.

[0056] Example 4

[0057] like Figure 3As shown, the present invention proposes a hydrodynamic adjustable speed rotary bar screen cleaner. Compared with embodiment one, the difference in this embodiment is that the drive assembly includes a rotating shaft, a bracket 10 and a baffle 13.

[0058] The rotating shaft is installed at one end of the transmission assembly and is located behind the delivery pipe 7;

[0059] The bracket 10 is installed at the end of the rotating shaft and is rotatably connected to the rotating shaft;

[0060] There are multiple baffles 13, which are installed at equal intervals on the outside of the sleeve 12.

[0061] In an optional embodiment, the projected shape of the baffle 13 is arc-shaped, which is used to make the sewage discharged from the conveying pipe 7 flow along the arc trajectory, increase the contact area between the sewage and the blade, improve the driving efficiency, and reduce the resistance between the baffle 13 and the sewage on the outside, so that the movement of the baffle 13 is smoother.

[0062] In this embodiment, the rotating shaft is installed behind the conveying pipe 7 by the bracket 10, and the baffle 13 is located behind the conveying pipe 7. When the conveying pipe 7 discharges sewage, the sewage generates an impact force on the baffle 13, causing the baffle 13 to drive the rotating shaft to rotate on the bracket 10, thereby driving the entire drive assembly to work, realizing the power output and speed regulation function of the cleaning machine, and improving the cleaning efficiency.

[0063] Example 5

[0064] like Figure 3 As shown, the present invention proposes a hydrodynamic adjustable speed rotary bar screen cleaner. The difference between this embodiment and the first embodiment is that the rotating shaft includes a rotating rod 9, a support plate 11, and a sleeve 12.

[0065] The rotating rod 9 is installed at one end of the transmission assembly and is located behind the conveying pipe 7;

[0066] There are multiple support plates 11, which are installed in the middle of the machine body 1 and located behind the conveying pipe 7. The support plates 11 are arranged in a one-to-one correspondence with the conveying pipe 7.

[0067] The sleeve 12 is fitted onto the outside of the support plate 11 to fix the baffle 13 at the end of the conveying pipe 7, so that the sewage discharged from the conveying pipe 7 directly impacts the baffle 13.

[0068] In this embodiment, the sleeve 12 is mounted on the rotating rod 9 by the support plate 11, and the baffle 13 is mounted on the sleeve 12, so that there is a certain distance between the end of the rotating rod 9 and the end of the conveying pipe 7, ensuring that the sewage can evenly impact each baffle 13 when discharged, thereby driving the sleeve 12 to rotate, further driving the rotating rod 9 to rotate, realizing the stable operation and efficient speed regulation of the cleaning machine, and improving the overall cleaning effect.

[0069] In this invention, the machine body 1 removes sewage, while the connecting shell 4 intercepts the sewage after cleaning the machine body 1. This allows the sewage to flow into multiple connecting pipes 5 under its own pressure, reducing the cross-sectional area of ​​the sewage flow and ensuring uniform sewage flow velocity in each connecting pipe 5. The guide shell 6 guides the sewage flowing in the connecting pipes 5 to the conveying pipe 7, further reducing the cross-sectional area of ​​the sewage flow during the guiding process. This allows the sewage to directly impact the baffle 13 at a stable flow velocity. The baffle 13, through the cooperation of the support plate 11 and the sleeve 12, drives the rotating rod 9 to rotate on the bracket 10. At the same time, through the cooperation of the speed regulating gearbox 3 and the two chain drive structures 2, the rotational torque of the rotating rod 9 is transmitted to the connecting shaft 14, causing the connecting shaft 14 to drive the machine body 1 to rotate. The valve 8 adjusts the cross-sectional area of ​​the inner side of the conveying pipe 7, thereby adjusting the impact force of the sewage discharged from the conveying pipe 7. This, in turn, adjusts the rotation speed of the rotating rod 9 driven by the baffle 13, allowing the machine body 1 to perform sewage removal work at different operating speeds.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
