Description

Technical Field

[0001] This utility model belongs to the field of rainwater filtration technology, and more specifically, relates to a device for removing impurities from rainwater. Background Technology

[0002] Regarding rainfall, its most prominent characteristic is uneven flow. When the rainfall intensity is low, the amount of rainwater exceeding the amount infiltrated into the ground will form surface runoff, washing away garbage and debris, clogging storm drains, leaving streets covered in filth, affecting environmental sanitation and increasing the difficulty of post-rain cleanup. Heavy rain is characterized by its large instantaneous flow, rapid current, and powerful momentum. In severe cases, it can wash away the ground, leaving rainwater containing large amounts of sand, gravel, branches, and other debris. Rainwater containing sand and gravel flowing into storm drains can cause blockages, preventing the smooth drainage of urban stormwater and, in severe cases, causing urban flooding.

[0003] Currently, rainwater and sewage separation and pollutant source control are important aspects of urban construction. In order to fully meet environmental protection technical requirements, it is particularly necessary to set up small-scale pollutant interception structures at the source, which can effectively reduce sedimentation and blockage in rainwater pipes and alleviate the treatment pressure on subsequent sewage treatment plants. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for removing impurities from rainwater, thereby solving the problem of existing rainwater containing sand and gravel causing blockages in rainwater pipes.

[0005] To achieve the above objectives, this utility model provides a device for removing impurities from rainwater, comprising:

[0006] The filter chamber is sunken and has a stepped first platform, a second platform and a third platform at its lower end. A water inlet is located above the first platform and the third platform forms a water collection pit with the inner wall of the filter chamber.

[0007] A partition is disposed in the filter chamber, located between the second platform and the top of the filter chamber, dividing the filter chamber into a first chamber and a second chamber;

[0008] A lower grille is disposed between the partition and the second platform, and the space between the second grille and the first platform is filled with stones to form a filter groove structure.

[0009] A drain pipe is disposed between the lower grille and the sump, close to the second platform.

[0010] Optionally, a stone layer is formed by filling the space between the second grid and the first platform with stones, wherein the upper end of the stone layer is not higher than the first platform, and the upper end of the lower grid is not higher than the stone layer.

[0011] Optionally, an upper grille is provided between the top ends of the filter chambers.

[0012] Optionally, the first cavity and the second cavity are respectively provided with a first manhole and a second manhole.

[0013] Optionally, the inlet is provided with a vertical bar screen.

[0014] Optionally, the vertical grille is exposed above the ground.

[0015] Optionally, the inlet is provided with a flat bar screen.

[0016] Optionally, the flat grille is not installed above the ground.

[0017] Optionally, the stone material includes pebbles or boulders.

[0018] Optionally, the second platform between the lower grille and the sump is provided with a drainage channel or a gentle slope.

[0019] This utility model provides a device for removing impurities from rainwater, which has the following advantages:

[0020] 1. This device for removing impurities from rainwater utilizes a stepped structure to form a buffer platform, a filter tank, and a collection pit connected in sequence. After rainwater enters the first chamber, it is filtered by the filter tank and then discharged into the second chamber. The filter tank reduces the water flow velocity, allowing fine sediment to settle. Only the filtered rainwater is then discharged through a drain pipe, while the settled sediment is collected in the collection pit for unified treatment, reducing the risk of blockage in the drain pipe. Furthermore, when the rainwater flow is too large, some rainwater can overflow from the upper part of the partition into the second chamber, preventing backflow.

[0021] 2. This device for removing debris from rainwater solves the problem of mud and sand accumulating and clogging in rainwater containing a large amount of sand, gravel, branches and other ground debris, which washes away the ground. At the same time, it is simple to clean and maintain, low in cost, and suitable for use in various environments.

[0022] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0029] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0030] like Figure 1-3 As shown, a device for removing impurities from rainwater includes:

[0031] The filter chamber is a sunken design. At the bottom of the filter chamber, there are three platforms that descend in a stepped manner: a first platform 1, a second platform 2, and a third platform 3. An inlet 9 is located above the first platform 1, and the third platform 3 forms a water collection pit with the inner wall of the filter chamber.

[0032] The partition 4 is disposed in the filter chamber, located between the second platform 2 and the top of the filter chamber, dividing the filter chamber into a first chamber and a second chamber.

[0033] The lower grille 6 is disposed between the partition 4 and the second platform 2. Stone material is filled between the second grille and the first platform 1 to form a filter groove structure.

[0034] Drainage pipe 8 is installed between the lower grille 6 and the sump, near the second platform 2.

[0035] Specifically, a stepped structure is used to form a buffer platform, a filter tank, and a collection pit connected in sequence. After rainwater enters the first chamber, it is filtered by the filter tank before being discharged into the second chamber. The filter tank reduces the water flow velocity, allowing fine silt in the water to settle. Only the filtered rainwater is then discharged through the drain pipe 8, while the settled silt is collected in the collection pit for unified treatment, reducing the risk of clogging in the drain pipe 8. At the same time, when the rainwater flow is too large, some rainwater can overflow from the top of the partition 4 into the second chamber, preventing rainwater backflow.

[0036] Furthermore, the first platform 1 allows rainwater to fall and collect, reducing the rainwater flow rate and separating larger impurities, while providing ample space to prevent debris from clogging the water flow. The drain pipe 8 maintains a certain gap with the second platform 2 to prevent the direct intake of settled silt.

[0037] Furthermore, the lower end of the partition plate 4 is provided with multiple through holes at intervals, and the two ends of the through holes are provided with vertical grooves, in which the lower grid 6 is slidably connected. The upper end of the through holes should be lower than the stone layer 7.

[0038] In this embodiment, a stone layer 7 is formed by filling the space between the second grid and the first platform 1 with stones. The upper end of the stone layer 7 is not higher than the first platform 1, and the upper end of the lower grid 6 is not higher than the stone layer 7.

[0039] Specifically, the stone layer 7 filters impurities, is low in cost, and is easy to maintain. At the same time, the stone layer 7 is not higher than the first platform 1, so that when the side of the stone layer 7 close to the first platform 1 is blocked, rainwater can still be filtered from the side of the stone layer 7 away from the first platform 1 through overflow, ensuring the filtration effect and working time of the stone layer 7.

[0040] In this embodiment, an upper grille 5 is provided between the top ends of the filter chambers.

[0041] Specifically, the upper grille 5 prevents some debris from entering the second cavity and blocking the drain pipe 8 when rainwater overflows from above the partition 4.

[0042] In this embodiment, the first cavity and the second cavity are respectively provided with a first manhole and a second manhole.

[0043] Specifically, the first and second manholes facilitate the cleaning and maintenance of the first and second cavities, respectively.

[0044] In this embodiment, the water inlet 9 is equipped with a vertical grille.

[0045] In this embodiment, the vertical grille is exposed above the ground.

[0046] Specifically, rainwater is filtered through vertical grilles.

[0047] In this embodiment, the inlet 9 is equipped with a flat grille.

[0048] In this embodiment, the flat grille is installed no higher than the ground level.

[0049] In this embodiment, the stone material includes pebbles or boulders.

[0050] In this embodiment, the second platform 2 between the lower grille 6 and the water collection pit is provided with a diversion channel or a gentle slope.

[0051] Specifically, the diversion channel or gentle slope facilitates the collection of fine sediment into the sump.

[0052] In this embodiment, the device for removing impurities from rainwater is used, taking rainwater filtration as an example:

[0053] Rainwater enters the first chamber through inlet 9, falls onto the first platform 1, and then enters the second chamber through the filter structure, allowing the filtered rainwater to be discharged through drain pipe 8. The filter structure filters and reduces the flow rate, while also causing fine impurities to settle due to the reduced flow velocity, minimizing clogging of drain pipe 8. The settled impurities are collected in a collection pit for centralized treatment. When there is excessive rainwater, it can enter the second chamber through the upper grille 5 above the partition 4.

[0054] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
