Technical Field

[0001] This utility model relates to the field of suspended solids filtration technology, and in particular to a suspended solids filtration device for a building rainwater harvesting system. Background Technology

[0002] Suspended solids are organic and inorganic particulate matter suspended in water that cannot pass through 0.45-micron filter paper or filters;

[0003] Suspended solids refer to solid matter suspended in water, including insoluble inorganic and organic matter, as well as silt, clay, and microorganisms. The suspended solids content in water is one of the indicators for measuring the degree of water pollution. Suspended solids are a major cause of water turbidity. Organic suspended solids in water bodies are prone to anaerobic fermentation after sedimentation, leading to water quality deterioration.

[0004] Commonly used large-scale suspended solids filtration devices have complex processes and many operating devices that are relatively independent of each other. Therefore, the construction cost of suspended solids filtration devices is high. Even after the entire device is built, the subsequent daily operation is a tedious task. If any link is neglected or damaged and not properly handled, it is very likely to cause the entire device to be damaged or even paralyzed.

[0005] Secondly, the use of water resources after suspended solids filtration is usually for cooling of air conditioning systems in commercial buildings within the community, as well as for fire-fighting water between floors. Its use for individual residents is still relatively lacking.

[0006] To address the above issues, we have developed a suspended solids filtration device for building rainwater harvesting systems. Utility Model Content

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] This utility model discloses a suspended solids filtration device for a building rainwater harvesting system.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a suspended solids filtration device for a building rainwater harvesting system includes a water storage tank. Four first fixed blocks 2 are symmetrically and equidistantly fixedly connected to the water storage tank 1. Bearings 3 are fixedly connected to each pair of first fixed blocks 2. Threaded rods 4 are rotatably connected between the pairs of bearings 3. Smooth rods 5 are fixedly connected between the pairs of first fixed blocks 2. Movable blocks 6 are slidably connected to the smooth rods 5. The movable blocks 6 are threadedly connected to the threaded rods 4.

[0027] In this embodiment: when the motor drives the threaded rod 4 to rotate, the threaded rod 4 drives the movable block 6 to move on the smooth rod 5 through a threaded connection. When rotating in the opposite direction, it can move in the opposite direction, thereby realizing the back-and-forth movement of the movable block 6. The bearing in the fixed block can support the rotation of the threaded rod, reduce the coefficient of friction during its movement, and ensure its rotational accuracy.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a filter screen 7 is slidably connected inside the movable block 6, a handle 8 is fixedly connected to the filter screen 7, and two rectangular blocks 9 are symmetrically fixedly connected to the filter screen 7. A limit block 10 is fixedly connected to the bottom of each of the two rectangular blocks 9, and a first hole 11 is opened in each of the two limit blocks 10.

[0029] In this embodiment: when the suspended matter in the water storage tank 1 is too small, the staff can remove the filter screen 7 by lifting it by the handle 8, and replace the filter screen 7 with a suitable one according to the size of the suspended matter in the water storage tank 1.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, two second holes 12 are symmetrically provided in the movable block 6, and two third holes 13 are symmetrically provided in the movable block 6. Each second hole 12 is connected to a third hole 13. A spring 14 is fixedly connected in each of the two third holes 13. A limit rod 15 is fixedly connected to the side of each of the two springs 14. The two limit rods 15 extend through the movable block 6 to the outside. A sleeve 16 is fixedly connected to the side of each of the two limit rods 15.

[0031] In this embodiment: when the filter screen 7 is inserted into the movable block 6, the circular end face of the limiting block 10 is pressed down to press the limiting rod 15 into the third hole 13. Then, the limiting block 10 is pressed down further. When the first hole 11 on the limiting block 10 is aligned with the limiting rod 15, the limiting rod 15 will be inserted into the first hole 11 due to the action of the spring, thereby achieving the purpose of auxiliary limiting of the filter screen 7 and the movable block 6. When the filter screen 7 needs to be replaced, the limiting block 10 can be pulled out by applying upward force to separate the filter screen 7 and the movable block 6.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment, a second fixing block 17 is fixedly connected to the water storage tank 1, a signal rod 18 is fixedly connected inside the second fixing block 17, a water level detector 19 is fixedly connected at equal intervals on the signal rod 18, and a water level alarm 20 is fixedly connected to the side of the signal rod 18.

[0033] In this embodiment: when the water level in the reservoir 1 reaches the danger level, the water level detector 19 transmits the signal to the water level alarm 20 through the signal rod 18. The water level alarm 20 is connected to external electronic equipment, and the staff can receive the message to filter the suspended matter in the reservoir 1.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, an inlet pipe 21 is fixedly connected to the side of the water storage tank 1, and an outlet pipe 22 is fixedly connected to the side of the water storage tank 1.

[0035] In this embodiment, rainwater from the building is collected into the storage tank 1 through the inlet pipe 21. After the suspended solids are filtered out, it can be pumped out through the outlet pipe 22 for use.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a water pump 23 is placed on the ground, the output end of the water pump 23 is connected to the water outlet pipe 22, and a motor 24 is fixedly connected to the water storage tank 1, the output end of the motor 24 is connected to the threaded rod 4.

[0037] In this embodiment, the operator starts the water pump 23 and the motor 24 using an external control device. The water pump 23 and the motor 24 make the equipment run, and both can be turned off at the same time when the operation is finished, which is convenient for control.

[0038] Working principle: When the water level in the reservoir 1 reaches the danger level, the water level detector 19 transmits the signal to the water level alarm 20 through the signal rod 18. The water level alarm 20 is connected to external electronic equipment, and the staff can receive the message to filter the suspended matter in the reservoir 1. First, the threaded rod 4 is driven by the motor to rotate. The threaded rod 4 drives the movable block 6 to move on the smooth rod 5 through the threaded connection, thus achieving the first filtration. After cleaning the suspended matter, the threaded rod 4 is rotated in the opposite direction to return to the original position. The filter screen 7 is removed by the handle 8. The appropriate filter screen 7 is replaced according to the size of the suspended matter in the reservoir 1 to achieve the second filtration. The above process is repeated to achieve repeated filtration. Finally, the filtered water is used by the water pump 23 for irrigation of gardens, lawns and crops or for washing family vehicles.

[0039] The entire structure works in concert to filter suspended solids in the water storage tank 1, effectively enabling rainwater reuse and reducing reliance on tap water.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
