Description

Technical Field

[0001] This utility model relates to the field of secondary water supply equipment, and in particular to a water tank rotation disturbance device for secondary water supply. Background Technology

[0002] In a secondary water supply system, the water in the tank flows directly in through the inlet pipe, and the direction of the inlet flow remains unchanged. Therefore, theoretically, the main flow path of the water inside will not change. This situation will lead to poor flow in some parts of the tank, making it very easy for bacteria and impurities to grow, affecting the hygiene of the tank. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a rotating agitation device for secondary water supply tanks. By installing a centrifugal impeller in the inlet pipe that can agitate the surrounding water, the water in the secondary water supply tank can be circulated, preventing localized stagnant water and improving the hygiene of the secondary water supply tank.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a water tank rotation disturbance device for secondary water supply, including a water inlet pipe and a centrifugal impeller;

[0005] The inlet pipe is fitted with a rotating cylinder, which can rotate circumferentially relative to the inlet pipe but cannot slide axially.

[0006] The centrifugal impeller and the rotating drum are coaxially fixed, and the end of the water inlet pipe extends to the axial inlet of the centrifugal impeller.

[0007] This solution is installed in the secondary water supply tank. The external pipe is connected to the inlet pipe. The external water flows from the inlet pipe to the shaft inlet of the centrifugal impeller and then flows outward. Because it flows outward through the centrifugal impeller, the water flow is diffused outward, avoiding water flow to concentrate in one place and avoiding stagnant water. In addition, the outward flow of water will drive the centrifugal impeller to rotate, further agitating the water in the tank, so that the water in the tank can be more fully circulated.

[0008] Preferably, a plurality of first centrifugal blades are evenly distributed around the axial periphery of the front end face of the centrifugal impeller. When the centrifugal impeller rotates under the influence of the incoming water, the first centrifugal blades fixed on the front end face will rotate together, thereby disturbing the water at the front end of the centrifugal impeller and preventing stagnant water in the front area.

[0009] Preferably, the first centrifugal blade has a circular arc structure, which can improve the disturbance effect.

[0010] Preferably, a plurality of second centrifugal blades are evenly distributed around the rear end face of the centrifugal impeller. When the centrifugal impeller rotates under the influence of the incoming water, the second centrifugal blades fixed on the rear end face will rotate together, thereby disturbing the water at the rear end of the centrifugal impeller and preventing stagnant water in the rear area.

[0011] Preferably, the second centrifugal blade has a circular arc structure, which can improve the disturbance effect.

[0012] Preferably, a limiting plate is provided around the end of the water inlet pipe, which is used to prevent the rotating drum from separating from the water inlet pipe. This can improve the stability of the cooperation between the water inlet pipe and the rotating drum.

[0013] Preferably, a planar thrust bearing is provided between the limiting plate and the end of the rotating drum. When water flows out from the inlet pipe, the rotating drum will experience axial sliding force relative to the inlet pipe. Using a planar thrust bearing can reduce friction and facilitate relative rotation.

[0014] Preferably, a radial ball bearing is provided between the water inlet pipe and the rotating drum. This reduces friction and facilitates relative rotation.

[0015] Advantages of this utility model:

[0016] This solution involves installing a centrifugal impeller in the inlet pipe that can agitate the surrounding water, thereby driving the water flow in the secondary water supply tank, preventing localized stagnant water, and improving the hygiene of the secondary water supply tank.

[0021] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0022] Example

[0023] like Figure 1 As shown, a water tank rotation disturbance device for secondary water supply includes an inlet pipe 3 and a centrifugal impeller 1; the inlet pipe 3 is fitted with a rotating cylinder 2, which can rotate relative to the inlet pipe 3 in a circular manner but cannot slide axially; the centrifugal impeller 1 and the rotating cylinder 2 are coaxially fixed, and the end of the inlet pipe 3 extends to the axial inlet of the centrifugal impeller 1.

[0024] This solution is installed in the secondary water supply tank. The external pipe is connected to the inlet pipe 3. The external water flows from the inlet pipe 3 to the shaft inlet of the centrifugal impeller 1, and then flows outward. Since it flows outward through the centrifugal impeller 1, the water flow diffuses outward, avoiding the water flow from concentrating in one place and avoiding stagnant water. In addition, during the outward flow of water, the centrifugal impeller 1 will be driven to rotate, further agitating the water in the tank, so that the water in the tank can be more fully circulated.

[0025] The centrifugal impeller 1 has several first centrifugal blades 5 evenly distributed around its front end shaft. When the centrifugal impeller 1 rotates under the influence of the incoming water, the first centrifugal blades 5 fixed on the front end will rotate together, thereby disturbing the water at the front end of the centrifugal impeller 1 and preventing stagnant water in the front area.

[0026] The first centrifugal blade 5 has a circular arc structure, which can improve the effect of disturbance.

[0027] The centrifugal impeller 1 has several second centrifugal blades 4 evenly distributed around its rear end face. When the centrifugal impeller 1 rotates due to the inlet water, the second centrifugal blades 4 fixed on the rear end face will rotate together, thereby disturbing the water at the rear end of the centrifugal impeller 1 and preventing stagnant water in the rear area.

[0028] The second centrifugal blade 4 has a circular arc structure, which can improve the disturbance effect.

[0029] A limiting plate is provided around the end of the water inlet pipe 3. The limiting plate is used to prevent the rotating drum 2 from separating from the water inlet pipe 3. This can improve the stability of the cooperation between the water inlet pipe 3 and the rotating drum 2.

[0030] A planar thrust bearing is provided between the limiting plate and the end of the rotating drum 2. When water flows out from the inlet pipe 3, the rotating drum 2 will experience axial sliding force relative to the inlet pipe 3. Using a planar thrust bearing can reduce friction and facilitate relative rotation.

[0031] A radial ball bearing is installed between the water inlet pipe 3 and the rotating drum 2. This reduces friction and facilitates relative rotation.

[0032] Advantages of this utility model:

[0033] This solution involves installing a centrifugal impeller 1 in the inlet pipe 3, which can agitate the surrounding water body, thereby driving the water flow in the secondary water supply tank, preventing local stagnant water, and improving the hygiene of the secondary water supply tank.
