Description

Technical Field

[0001] This utility model relates to the field of rainwater filtration and collection technology, and in particular to a composite vortex 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

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5 It is known that a composite cyclone filtration device includes a housing 1, with an inlet 2 and an outlet 3 respectively provided on both sides of the housing 1. Inside the housing 1, there is a sloping baffle 4 near the inlet 2 and a basket 5 near the outlet 3. A collision plate 6 is provided between the sloping baffle 4 and the basket 5. The basket 5 has a collection hole 7 on the side facing the inlet 2. The basket 5 is hollow inside and has a filter hole 8 on its outer wall. Rainwater enters the housing 1 from the inlet 2, passes through the sloping baffle 4 and the collision plate 6, and then enters the basket 5. After filtration, it is discharged from the outlet 3.

[0023] In practical use, this utility model

[0024] When this device is connected to the front end of the rainwater harvesting system, rainwater enters the housing 1 through the inlet 2, passes through the inclined baffle 4, and forms a swirling vortex along the inclined direction of the baffle 4. Then, it forms a collision separation effect with the collision plate 6. Some water enters the basket 5 through the collection hole 7, and some water enters the basket 5 through the filter hole 8 on the outer wall of the basket 5. Finally, after being filtered by the basket 5, it is discharged from the outlet 3.

[0025] Inside this device, due to the presence of the inclined folding plate 4 and the collision plate 6, a special water channel is formed, and the water will form a circulating vortex inside the shell 1 to continuously flush and reduce the accumulation of silt.

[0026] The inclined folding plate 4 forms a 45° angle with the horizontal plane. There are three inclined folding plates 4. The inclined folding plate 4 is equipped with a support 9 on the outside. The support 9 is welded from 0.8mm thick 304 stainless steel square tube. Both the inclined folding plate 4 and the basket 5 are made of 1mm 304 stainless steel plate. There are four horizontal plates 10 on the collision plate 6. After assembly, the inclined folding plate 4 and the horizontal plates 10 are spaced apart.

[0027] The bracket 9 can improve the stability of the inclined plate 4 and facilitate the removal of the inclined plate 4 for cleaning and maintenance. The three inclined plates 4 and the four horizontal plates 10 are arranged at intervals, so that when water flows from the inclined plates 4 into the horizontal plates 10, a collision separation effect is formed.

[0028] Water enters the inclined baffle 4 and is repeatedly deflected, causing the particles to hang down naturally, avoiding direct flow when the water volume is large. This allows heavier particles to be collected at the bottom of the shell 1 for final cleaning.

[0029] The collision plate 6 can also be removed from the housing 1 for cleaning, facilitating inspection and maintenance.

[0030] When water enters between the two inclined baffles 4, it can generate a vortex when the water volume is large, which increases the local flow velocity of the water and enhances the filtration capacity.

[0031] The basket 5 is provided with a cover plate 11, and a handle 12 is provided on the cover plate 11 to facilitate the removal of the basket 5 and the cleaning of the impurities collected inside. The cover plate 11 has an extension edge on the side to facilitate the positioning of the basket 5 and to keep the basket 5 in a vertical position when it is taken out or put in.

[0032] Compared with the prior art, this utility model has the following advantages: after rainwater enters the equipment, it will form a swirling vortex state, which will repeatedly flush away the blockage and avoid blockage, thereby improving the filtration efficiency.
