Description

Technical Field

[0001] The utility model relates to the technical field of filter core replacement, in particular to a sponge city outdoor drainage filtering device with a filter core that can be easily replaced. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge. It can also be called a "water-elastic city". The international general term is "low-impact development rainwater system construction". When it rains, it absorbs, stores, infiltrates and purifies water. When needed, the stored water will be released and used to achieve the free migration of rainwater in the city. The construction of sponge cities should follow the principle of ecological priority, combine natural methods with artificial measures, and maximize the accumulation, infiltration and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and flood prevention, so as to promote the utilization of rainwater resources and the protection of the ecological environment. The construction of "sponge city" is not to start from scratch and replace the traditional drainage system, but to "reduce the burden" and supplement the traditional drainage system to maximize the role of the city itself. In the process of sponge city construction, the systematic nature of natural precipitation, surface water and groundwater should be coordinated, and the various links of water recycling such as water supply and drainage should be coordinated, and its complexity and long-term nature should be considered.

[0003] The current sponge city outdoor drainage filtration device with easily replaceable filter elements filters debris through a filter net, but the filter net is inconvenient to replace, resulting in clogging of the filter net after long-term use, resulting in reduced filtration efficiency and failure to quickly and effectively separate sludge. Therefore, we propose a sponge city outdoor drainage filtration device with easily replaceable filter elements. Utility Model Content

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1-4 As shown, the utility model is a sponge city outdoor drainage filtration device that can easily replace the filter element, including a rainwater filter box 1, a tool box 2 is symmetrically fixedly connected to the two sides of the rainwater filter box 1, springs 3 are fixedly connected to the two sides inside the rainwater filter box 1, the top of the spring 3 is fixedly connected to a limiting groove 4, the inside of the limiting groove 4 is detachably connected to a limiting block 5, the top of the limiting block 5 is fixedly welded with an arc filter plate 6, one side of the limiting groove 4 is fixedly connected to a moving block 7, a handle 8 is provided inside the tool box 2, and the handle 8 is rotatably connected to the moving block 7, and the top of the tool box 2 is rotatably connected to a moving door 9 through a hinge.

[0024] Among them, the lower end of the rainwater filter box 1 is fixedly connected to the rainwater treatment box 10, and U-shaped plates 11 are symmetrically fixedly welded on both sides of the bottom of the rainwater treatment box 10. The inside of the U-shaped plate 11 is fixedly welded with an extrusion spring 12. By setting the extrusion spring 12, the filter net can be limited to facilitate subsequent disassembly.

[0025] Among them, one end of the extrusion spring 12 is fixedly welded with a limit plate 13, one end of the limit plate 13 is detachably connected with an impurity filter screen 14, a hydraulic cylinder 15 is fixedly installed on one side of the rainwater treatment box 10, and the output end of the hydraulic cylinder 15 is fixedly connected with a push plate 16. By setting the push plate 16, sand and gravel in the water flow will not accumulate on the surface of the filter screen 14.

[0026] Among them, the pushing plate 16 is fixedly welded with a sealing plate 18 through a connecting rod 17, and the pushing plate 16 is slidingly connected to the inside of the rainwater treatment box 10. By setting the sealing plate 18, impurities such as sand and gravel are pushed into the impurity treatment box 19, which can prevent mosquitoes and odors in the impurity treatment box 19.

[0027] Among them, an impurity treatment box 19 is fixedly welded on one side of the rainwater treatment box 10, and the surface of the impurity treatment box 19 is slidably connected with a movable plate 21 through a slide rail 20. A processing port 22 is opened at the bottom of the impurity treatment box 19. By setting the movable plate 21, when the impurity treatment box 19 needs to be cleaned, the movable plate 21 is slid to facilitate the cleaning of impurities in the cylinder.

[0028] A rainwater storage box 23 is fixedly connected to the lower part of the U-shaped plate 11 , and a water outlet pipe 24 is fixedly connected to one side of the rainwater storage box 23 , through which the filtered rainwater is reused for a second time.

[0029] A sealing strip is provided at the bottom of the movable plate 21, and a sealing ring is provided at the upper end of the processing port 22. The sealing ring is provided to prevent mosquitoes and odor from leaking.

[0030] Working principle: When used on rainy days, rainwater, debris, soil, sand and gravel are filtered through the curved filter plate 6. Larger debris is filtered by the curved filter plate 6 and then falls into the rainwater storage box 23 through the filter screen 14; when the soil, sand and gravel fall on the surface of the filter screen 14 through the curved filter plate 6, the hydraulic cylinder 15 is started, and the output end of the hydraulic cylinder 15 pushes the push plate 16 to push the sand and gravel and other impurities accumulated on the surface of the filter screen 14 into the impurity treatment box 19 for collection, so that the sand and gravel and other impurities in the water flow will not accumulate on the surface of the filter screen 14, solving the problem that the filtered impurities accumulate on the filter screen 14 and will clog the filter screen 14 if not cleaned in time. By opening the movable door 9 and turning the handle 8 vertically, the filter screen 14 is moved downward. By pressing, the movable block 7 drives the limiting groove 4 to be pressed downward, so that the limiting block 5 is disassembled and separated from the limiting groove 4, and the arc filter plate 6 can be disassembled, cleaned and replaced. By squeezing the limiting plate 13 like the extrusion spring 12, the limiting plate 13 cancels the limitation on the filter screen 14, so that the filter screen 14 can be disassembled, cleaned and replaced, which greatly saves the labor for replacement and makes the use of the device more convenient. By sliding the movable plate 21, it is convenient to clean the impurities in the impurity treatment box 19. The setting of the sealing ring and the sealing strip facilitates the sealing of the movable plate 21 and the side wall of the treatment port 22 to prevent impurities from overflowing and prevent mosquitoes and odors from leaking. Through the outlet pipe 24, the filtered rainwater is reused for a second time.
