Description
Technical Field
[0001] The utility model relates to the technical field of rainwater treatment, and in particular to a device combining wetland and rainwater reuse. Background Art
[0002] Artificial wetlands are an emerging sewage treatment technology that has developed rapidly throughout the world with its advantages of low investment cost, high purification efficiency and simple maintenance. It is widely used in the treatment of agricultural, landscape water and domestic sewage. It has good removal functions and effects on organic pollutants, as well as nitrogen and phosphorus in sewage. It uses the physical, chemical and biological synergistic effects of soil, plants, artificial media and microorganisms in artificial wetlands to treat rainwater. At present, the artificial wetland rainwater collection system is a technology that relies on collecting rainwater and reusing it after simple sedimentation and filtration. The treated rainwater can be used as grey water, such as flushing toilets, watering green spaces, spraying roads or recharging underground to achieve zero rainwater discharge.
[0003] After rainwater is recycled, it is necessary to filter impurities in the rainwater through a purification and reuse device. However, during use of the purification and reuse device in the prior art, the water inlet pipe usually directly faces the filter screen, which causes the area of the filter screen below the water inlet pipe to be easily damaged by the long-term flushing of the water flow. In this case, the area in the middle of the filter screen bears a greater filtration pressure, while the edge area of the filter screen bears a lower filtration pressure, resulting in a lower utilization rate of the edge area of the filter screen, affecting the filtration efficiency. How to invent a method to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content
[0004] In order to make up for the above deficiencies, the utility model provides a wetland and rainwater reuse combined device, which aims to improve the purification and reuse device under the prior art. During use, the water inlet pipe usually directly faces the filter screen, which causes the area of the filter screen located below the water inlet pipe to be easily damaged by the long-term scouring of the water flow. In this case, the area in the middle of the filter screen bears a greater filtration pressure, while the edge area of the filter screen bears a lower filtration pressure, resulting in a low utilization rate of the edge area of the filter screen, affecting the filtration efficiency.
[0005] The utility model is achieved in this way:
[0006] The utility model provides a wetland and rainwater recycling combined device, comprising a box body, the box body is connected with a water inlet pipe and a drain pipe, the interior of the box body is provided with a filter plate, an expansion plate and a water distribution plate, the upper end of the water distribution plate is provided with a drainage filter cartridge and an arc plate, the arc plate is connected with a plurality of diversion plates, the arc plate is provided with a plurality of water flow holes of the same size on the side wall between two adjacent diversion plates, the box body is connected with a limiting cylinder, the water distribution plate is connected with a reset spring, a groove is provided on the side wall of the water distribution plate, a plurality of evenly distributed water distribution holes are provided on the inner wall of the groove away from the opening, and the groove is spiral.

[0008] Preferably, the inner wall of the limiting cylinder is slidably connected to one end of the drainage filter cylinder, and the limiting cylinder and the drainage filter cylinder are both in a "T" shape.
[0009] By adopting the above technical solution, the limiting cylinder can block the drainage filter cylinder.
[0010] Preferably, the lower end of the drainage filter cartridge is fixedly connected to the water distribution plate, the drainage filter cartridge is located outside the arc plate, and the arc plate is fixedly connected to the water distribution plate.
[0011] Preferably, the inner wall of the box is fixedly connected to the expansion plate, the expansion plate is annular, a support ring is fixedly connected to the upper side wall of the expansion plate, and the side wall of the expansion plate is provided with a plurality of arc-shaped buffer holes which expand outwards in a circular array respectively and sequentially.
[0012] By adopting the above technical solution, the water discharged from the drainage filter cartridge can be accumulated on the expansion plate between the support ring and the inner wall of the box body, so that the water flows through a plurality of buffer holes to fall.
[0013] Preferably, a fixing ring is fixedly connected to the inner wall of the box body, the fixing ring is fixed to the filter plate by bolts, and the filter plate and the opposite side walls of the water distribution plate are fixedly connected to the two ends of the reset spring respectively.
[0014] By adopting the above technical solution, the water pressure can drive the water distribution plate to squeeze the reset spring, thereby extending one end of the drainage filter cartridge out of the limiting cylinder to discharge excess rainwater, and reset it through the reset spring after the discharge is completed.
[0015] The beneficial effects of the utility model are:
[0016] The rainwater is transported to the interior of the limit cylinder through the water inlet pipe. In the initial state, the limit cylinder and the drainage filter cylinder are in a sealed state. At this time, the rainwater is buffered by the arc surface of the arc plate, and then drops to the water distribution plate through the water flow hole for a second buffering. After that, the rainwater flows into the inside of the groove and then falls to the filter plate through the water distribution hole for filtration; when the amount of rainwater entering is large, the water pressure inside the limit cylinder is strengthened. At this moment, the falling speed of the rainwater in the water flow hole is less than the water storage speed inside the limit cylinder. At this moment, the reset spring is compressed, the water distribution plate moves downward, and the outer diameter of the water distribution plate is smaller than the inner diameter of the support ring. At the same time, one end of the drainage filter cylinder gradually extends out of the limit cylinder. At this moment, excess rainwater is discharged from the drainage hole on the side wall of the drainage filter cylinder to the surface of the expansion plate, and then drips to the periphery of the filter plate through the buffer hole for filtration, so as to perform multi-level buffering on the rainwater, reduce the burden of the filter screen, ensure its service life, and improve the utilization rate and filtration effect.

[0026] Furthermore, the upper side wall of the box body 1 is fixedly connected to the water inlet pipe 2, and the inner wall of the box body 1 connected to the water inlet pipe 2 is fixedly connected to one end of the limiting cylinder 8.
[0027] It should be noted that: rainwater is transported to the interior of the limit cylinder 8 through the water inlet pipe 2. In the initial state, the limit cylinder 8 and the drainage filter cylinder 11 are in a sealed state. At this time, the rainwater is buffered by the arc surface of the arc plate 12, and then falls onto the water distribution plate 17 through the water flow hole 13 for a second buffering. After that, the rainwater flows into the interior of the groove 15 and then falls onto the filter plate 5 through the water distribution hole 16 for filtration.
[0028] Reference Figure 3-4 , further; the inner wall of the limit cylinder 8 is slidably connected to one end of the drainage filter cylinder 11, and the limit cylinder 8 and the drainage filter cylinder 11 are both in a "T" shape; the lower end of the drainage filter cylinder 11 is fixedly connected to the water distribution plate 17, and the drainage filter cylinder 11 is located on the outside of the arc plate 12, and the arc plate 12 is fixedly connected to the water distribution plate 17; the inner wall of the box body 1 is fixedly connected to the expansion plate 6, the expansion plate 6 is annular, and the upper side wall of the expansion plate 6 is fixedly connected with a support ring 9, and the side wall of the expansion plate 6 is provided with a number of arc-shaped buffer holes 7 that expand outward in a circular array respectively and in sequence; the inner wall of the box body 1 is fixedly connected with a fixing ring 4, and the fixing ring 4 and the filter plate 5 are fixed by bolts, and the filter plate 5 and the opposite side walls of the water distribution plate 17 are respectively fixedly connected to the two ends of the reset spring 10.
[0029] It should be noted that: when a large amount of rainwater enters, the water pressure inside the limit cylinder 8 is strengthened. At this moment, the falling speed of rainwater in the water flow hole 13 is less than the water storage speed inside the limit cylinder 8. At this moment, the reset spring 10 is compressed, the water distribution plate 17 moves downward, and the outer diameter of the water distribution plate 17 is smaller than the inner diameter of the support ring 9. At the same time, one end of the drainage filter cylinder 11 gradually extends out of the limit cylinder 8.

In the initial state, the limiting cylinder 8 and the drainage filter cylinder 11 are in a sealed state. At this time, the rainwater is buffered by the curved surface of the arc plate 12, and then the rainwater is lowered to the water distribution plate 17 through the water flow hole 13 for a second buffering. After that, the rainwater flows into the interior of the groove 15 and then falls to the filter plate 5 through the water distribution hole 16 for filtration; when the amount of rainwater entering is large, the water pressure inside the limiting cylinder 8 is strengthened. At this moment, the falling speed of the rainwater in the water flow hole 13 is less than the water storage speed inside the limiting cylinder 8. At this moment, the reset spring 10 is compressed, the water distribution plate 17 moves downward, and the outer diameter of the water distribution plate 17 is smaller than the inner diameter of the support ring 9. At the same time, one end of the drainage filter cylinder 11 gradually extends out of the limiting cylinder 8. At this moment, excess rainwater is discharged from the drainage hole on the side wall of the drainage filter cylinder 11 to the surface of the expansion plate 6, and then drips to the periphery of the filter plate 5 through the buffer hole 7 for filtration, and finally discharged from the drain pipe 3.
