Description

Technical Field

[0001] This utility model belongs to the field of rainwater technology, specifically a rainwater purification device. Background Technology

[0002] Against the backdrop of global water scarcity and accelerated urbanization, rainwater, as a renewable freshwater resource, has become an important way to alleviate urban water supply pressure and reduce non-point source pollution through its recycling and utilization. Rainwater purification devices, as core equipment for rainwater resource utilization, collect, filter, and purify rainwater from different sources such as rooftops, roads, and green spaces. The treated rainwater can then be used for irrigation, toilet flushing, and landscape water replenishment, playing a crucial role in the construction of "sponge cities" and water resource recycling systems.

[0003] However, existing rainwater purification devices commonly face clogging problems in practical applications, becoming a major bottleneck restricting their efficient operation. Specifically, impurities carried by rainwater continuously accumulate on the filter surface, gradually forming a filter cake layer, leading to clogging of the filter pores, reduced flow area, increased filtration resistance, and decreased rainwater throughput. In severe cases, it can even completely block water flow, forcing the device to shut down. At the same time, filter clogging exacerbates the scouring and entrainment of impurities by the water flow, causing some unfiltered impurities to directly enter subsequent treatment units, reducing the quality of purified water.

[0004] Therefore, this utility model provides a rainwater purification device. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a rainwater purification device is proposed.

One side of the surface of the insert 61 is fixedly installed with the support rod 62, and the side of the support rod 62 away from the insert 61 is fixedly installed with the collection hopper 63. The collection hopper 63 is located on top of the filter screen 53 and is movably connected to the filter screen 53. The drive assembly 7 includes a support frame 71 and a waterproof shell 72. The support frame 71 is fixedly installed on the inner wall of the collection hopper 63, and the side of the support frame 71 away from the collection hopper 63 is fixedly installed with the waterproof shell 72. The waterproof shell 72 has a built-in servo motor. The cleaning assembly 8 includes a screw 81 and a scraper 82. The screw 81 is rotatably installed on the bottom of the inner wall of the filter screen 53. The bottom of the surface of the screw 81 is threadedly installed with the scraper 82. The top of the screw 81 is movably engaged with the servo motor built into the waterproof shell 72. The limiting assembly 9 includes a groove 91 and a guide rod 92. The groove 91 is opened on both sides of the surface of the scraper 82. The guide rod 92 is fixedly installed on the side of the inner wall of the filter screen 53 near the groove 91. The guide rod 92 is located in the groove 91. The surface of the sedimentation tank 3 is provided with an observation window 100.

[0026] like Figures 1 to 5As shown, the combined use of connecting plate 51, fixing ring 52, and filter screen 53 can filter rainwater, removing large impurities to prepare for subsequent purification. The combined use of insert block 61, support rod 62, and collection hopper 63 effectively collects rainwater and allows for quick disassembly for maintenance and cleaning of filter screen 53, thus improving collection efficiency. The combined use of support frame 71 and waterproof shell 72 provides stable support for the servo motor built into the waterproof shell 72, along with efficient waterproofing, ensuring normal operation. Damage may occur. The screw 81 and scraper 82 work together to rotate through the servo motor built into the waterproof housing 72, allowing the scraper 82 to rise slowly. This scrapes away impurities from the inner wall of the filter screen 53 and cleans the filter screen 53. The groove 91 and guide rod 92 work together to guide the scraper 82, allowing it to move axially along the screw 81 and rise normally. The observation window 100 allows the user to easily observe the rainwater sedimentation inside the sedimentation tank 3 from the outside. Once sedimentation is complete, the gate can be opened to drain the water.

[0027] Working principle: During operation, first place the support leg 1 on a flat surface, then align the insert 61 with the connecting plate 51 and insert it downwards into the connecting plate 51. After insertion, the collecting hopper 63 will align with the filter screen 53. During insertion, the output end of the motor built into the waterproof shell 72 needs to be engaged with the screw 81. Then it can be used. When it rains, rainwater will flow into the filter screen 53 through the collecting hopper 63 and filter the impurities in the water through the filter screen 53. Then the water will flow into the sedimentation tank 3 for sedimentation. After sedimentation, the user first opens the discharge port 4 to discharge the sludge settled at the bottom. After discharge, connect the discharge port 4 to the water pipe to reuse the clean water. When the filter screen 53 is clogged, first start the motor built into the waterproof shell 72 to drive the screw 81 to rotate. The rotation of the screw 81 will drive the scraper 82 to rise. During the rise, the scraper 82 will scrape off the impurities on the inner wall of the filter screen 53. Then the user removes the collecting hopper 63 and cleans the impurities to complete the unclogging effect.
