Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting and filtration technology, and in particular to a centrifugal vortex diversion filtration device. Background Technology

[0002] Rainwater filtration devices filter impurities in rainwater. After initial filtration and screening, the rainwater is transported to a storage tank. Filtration is required in both light and heavy rainfall. The rainwater filter is buried underground and connected to the main rainwater pipe network. Rainwater entering the storage tank requires rapid filtration. In rapid filtration systems, sediment and particulate matter need to be filtered, collected, and cleaned. Existing filters in rapid filtration systems are prone to clogging under increased rainwater flow, resulting in reduced flow rate, low filtration efficiency, and difficulty in cleaning. When filtering impurities, it is also necessary to overcome the resistance generated during filtration. Even light rainwater flow also serves a filtration function, and rapid filtration can lead to clogging, thus affecting filtration efficiency. Utility Model Content

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 6 It is known that a centrifugal cyclone diversion filtration device includes a housing 1, an inlet 2 on the upper outer side of the housing 1, an outlet 3 on the lower outer side of the housing 1, a partition 4 at the bottom of the housing 1, a diversion chamber 5 at the bottom of the partition 4, a through hole 6 between the diversion chamber 5 and the interior of the housing 1, a valve 7 at the through hole 6, an annular filter screen 8 inside the housing 1, a rotating shaft 10 connected to the top of the housing 1 via a bracket 9, a plurality of blades 11 on the rotating shaft 10, a motor 12 and a generator 13 fixedly connected to the upper end of the rotating shaft 10, a cleaning plate 14 coaxially fixed to the bottom of the rotating shaft 10, and a diversion port 15 on the outer side of the diversion chamber 5.

[0018] In practical use, this utility model

[0019] Rainwater enters the housing 1 through the inlet 2, is filtered by the filter screen 8, and is discharged from the outlet 3. When the amount of rainwater is large, the valve 7 is opened, and the rainwater enters the diversion chamber 5 through the through hole 6 and is diverted.

[0020] During the filtration process, rainwater enters the housing 1 and washes the middle blades 11, generating power to rotate the shaft 10. This rotation disperses the rainwater. The rotating blades 11 drive the cleaning plate 14 to clean the bottom dirt, providing a cleaning effect. The rotating blades 11 create a swirling flow, causing heavy objects or impurities to swirl downwards and naturally flow out of the device through the discharge port 15. With a large water volume, the rotational power gradually increases, activating the upper motor 12 and generator 13 to generate electricity. The generator 13 can be connected to the power grid to transmit power. With a large flow rate, the upper sensor detects the speed increase or decrease and opens or closes the bottom discharge valve 7, thus diverting the flow. With a small amount of rainwater, the rainwater entering the housing 1 does not wash the side walls but flows downwards. When it washes over the blades 11, it still drives the blades 11 to rotate, thus dispersing the rainwater and providing a separation effect. Even if the blades 11 do not rotate for a long time, they still disperse the rainwater and wash the side walls because the blades 11 are at a 45° angle to the horizontal plane. A 45-degree tilt creates a height deviation, causing water to flow downwards at an angle through blade 11, resulting in a parabolic flow. If there is debris on blade 11 or baffle 4, motor 12 can be activated to rotate shaft 10 in reverse (counterclockwise) to dislodge the debris, thus achieving an automatic cleaning function. This counterclockwise rotation should only be initiated when there is no water or the rainfall is light, to avoid damaging shaft 10. In low water flow conditions, the diversion valve 7 automatically closes, allowing for the direct collection of rainwater and clean water.

[0021] The rotational speed of the shaft 10 can be obtained by a speed sensor installed on the shaft 10.

[0022] The axes of inlet 2 and outlet 3 do not intersect with the axis of shell 1. Rainwater enters shell 1 and is quickly flushed and rotated downwards through the side wall. The downward swirling flow can disperse through filter screen 8 for rapid filtration.

[0023] The cleaning plate 14 is located at the through hole 6. When it rotates, it can clean the through hole 6, prevent debris from clogging the through hole 6, and facilitate the discarding of flow.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] 1. The blades can sense the water flow rate by sensing the signal, and the rotation speed can predict the water flow rate.

[0026] 2. The flow rate is directly proportional to the water volume. When the water volume is small, close the diversion valve to collect rainwater and clean water directly.

[0027] 3. When water enters the device, it creates a vortex that disperses the rainwater, which helps to better filter impurities;

[0028] 4. When water enters the device, the blades will rotate and generate power, which drives the generator to collect electricity and transmit it to the power system.

[0029] 5. Time-saving and labor-saving, intelligent system; it can automatically clean itself when rotating automatically.
