Description

Technical Field

[0001] This utility model relates to the field of water purification and intake technology for reservoirs, and in particular to a multi-level composite ecological water intake and water purification integrated device. Background Technology

[0002] With rapid urbanization, water scarcity and pollution have become increasingly prominent, making traditional methods like direct drinking water and surface water supply insufficient to meet demand. Addressing the pain points of reservoir water intake, a new integrated reservoir water intake system has emerged. This equipment utilizes advanced filtration technology and a self-cleaning device to effectively remove suspended solids, pigments, organic matter, and heavy metals from the water, ensuring the treated drinking water meets national water quality standards. The equipment is highly efficient and energy-saving, employing automated control technology to reduce manual labor and lower daily maintenance costs. Furthermore, its design offers excellent scalability, adapting to water intake projects of varying sizes. This environmentally friendly equipment also boasts significant market potential and technological sophistication, making it an ideal choice for modern households and businesses seeking reservoir water intake solutions.

[0003] With the acceleration of urbanization, water pollution has become increasingly serious. Traditional water supply methods are unable to meet the water quality needs of households and places. Ecological water intake and integrated water purification equipment has emerged to address this issue. Through filtration technology, it effectively removes impurities such as suspended solids and pigments, ensuring the safety of drinking water. However, in practical applications, the filtration effect of some equipment is not good. The main reason is that the selection of filter materials is unreasonable or the design of the filter device is limited, resulting in a decrease in filtration efficiency and failure to completely remove harmful substances in the water. This problem not only affects the water intake effect, but may also cause harm to the environment.

[0004] In response to this technical problem, this application proposes a multi-level composite ecological water intake and water purification integrated device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-level composite ecological water intake and purification integrated device. Equipped with three-stage filtration—filter screen one, filter screen two, and filter screen three—it significantly improves water quality. During water intake, the water enters the delivery pipe through the funnel-shaped intake port. Under the centrifugal force of the spiral plate, impurities move outward, while clean water is extracted through the permeation mesh, achieving efficient purification and ensuring water supply safety and water quality improvement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-level composite ecological water intake and purification integrated device includes a reservoir body. A planting platform is fixedly connected to the bottom of the inner wall of the reservoir body. A base is fixedly connected to the inner wall of the planting platform. Several foundation piles are fixedly connected to the top of the base. A concrete platform is fixedly connected to the top of the foundation piles. A filter screen is fixedly connected to the outer wall of the concrete platform. Several traction ropes are fixedly connected to the outer wall of the filter screen. A connecting pipe is fixedly connected to the top of the reservoir body. A filter pipe is fixedly connected to the left end of the connecting pipe.

[0008] Furthermore, a second filter screen is fixedly connected to the inner wall of the coagulation platform, and a first filter screen is fixedly connected to the inner wall of the second filter screen at the top of the coagulation platform.

A base is constructed outside the water intake, equipped with a three-stage filter screen (filter one, filter two, and filter three), which significantly improves the water quality. When water is taken out, the water enters the delivery pipe through the funnel-shaped water intake. Under the centrifugal action of the spiral plate, impurities move to the outside, and clean water is extracted through the permeation net, achieving efficient purification and ensuring water supply safety and water quality improvement.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a multi-level composite ecological water intake and purification integrated device, comprising a reservoir body 1, a planting platform 2 fixedly connected to the bottom of the inner wall of the reservoir body 1, a base platform 3 fixedly connected to the inner wall of the planting platform 2, a plurality of foundation piles 4 fixedly connected to the top of the base platform 3, a concrete platform 5 fixedly connected to the top of the foundation piles 4, a filter screen 3 16 fixedly connected to the outer wall of the concrete platform 5, a plurality of traction ropes 9 fixedly connected to the outer wall of the filter screen 3 16, a connecting pipe 8 fixedly connected to the top of the reservoir body 1, a filter pipe 7 fixedly connected to the left end of the connecting pipe 8, a filter screen 2 15 fixedly connected to the inner wall of the concrete platform 5, a filter screen 14 fixedly connected to the inner wall of the filter screen 2 15 at the top of the concrete platform 5, a plurality of floats 10 fixedly connected to the outer wall of each traction rope 9, the floats 10 being rotatably connected to each other through an arc plate 11, an interception net 12 fixedly connected to the bottom of each arc plate 11, and a gravity block 13 fixedly connected to the bottom of the interception net 12.

[0025] Specifically: Based on the reservoir body 1, a multi-layered composite ecological water intake and purification integrated system is constructed. Its core structure adopts a gradient protection and purification design from the outside to the inside. The specific technical solution is as follows.

[0026] The protective belt adopts a modular combined structure, consisting of an inner, middle, and outer triple composite interception net 12. Each layer uses a high-strength polyethylene woven mesh (tensile strength ≥200kN / m) integrated with a polyurethane float 10 system. The net layers form a spatial mesh structure through 20mm diameter traction ropes 9. The floats 10 are connected by arc-shaped plates 11 to form a continuous floating platform. Lead-zinc alloy gravity blocks 13 (each weighing 50kg, spaced 2m apart) are installed at the bottom to achieve three-dimensional stability. The outer net uses 200-mesh (75μm pore size) oleophobic filter media, the middle layer is equipped with a 100-mesh (150μm pore size) anti-algae adhesion coating, and the inner layer is equipped with a 50-mesh (300μm pore size) composite photocatalytic material mesh, forming a triple interception of surface oil, algae, and suspended solids. The system utilizes the wave response characteristics of the float array to achieve an automatic accumulation capacity of 5-8 m³ of cyanobacteria per day. Submerged plants are planted between the interception net 12 and the base 3, and physical shading technology is used to inhibit algal photosynthesis, eliminating algal material between the interception net 12 and the base 3. This effectively improves the water transparency within the interception net 12, creating conditions for the restoration of submerged vegetation, inhibiting the growth of algal material in the upper and middle layers of the water, improving water transparency, and preventing clogging during filtration at the base 3.

[0027] The base 3 is constructed using a rock-filling and silt-squeezing process. It is constructed with 10-50cm granite blocks to form a 5m wide trapezoidal cross section. Φ800mm prestressed concrete pipe piles 4 (15m long, 3m spacing) are pre-embedded inside as the load-bearing structure. The top concrete platform 5 (C30 concrete, 1.2m thick) integrates a three-stage filtration unit. It is equipped with a 100μm pore size stainless steel wedge filter 14, made of SS304 material, with an opening rate of 38%. It is also equipped with a 50μm polyester melt-blown filter 15 with a dirt holding capacity of 800g / m² and a 20μm ceramic membrane filter 16 with a porosity of 40% and a flow rate of 50L / (m²·h).

[0028] Reference Figure 4 A water intake pipe 6 is fixedly connected to the left end of the filter pipe 7, and a horn-shaped water intake port 17 is fixedly connected to the right end of the connecting pipe 8. A conveying pipe 19 is fixedly connected to the left end of the inner wall of the connecting pipe 8. The outer wall of the conveying pipe 19 is installed on the inner wall of the filter pipe 7. A permeation mesh 20 is fixedly connected to the inner wall of the filter pipe 7. A spiral plate 21 is fixedly connected to the outer wall of the permeation mesh 20. The left end of the permeation mesh 20 is fixedly connected to the right end of the water intake pipe 6 and passes through it. A slag discharge pipe 18 is fixedly connected to the outer wall of the filter pipe 7. A slag discharge valve is installed at the bottom end of the slag discharge pipe 18.

[0029] Specifically: Based on the reservoir body 1, a multi-level composite ecological water intake and purification integrated system is constructed. Its core water intake process achieves efficient purification through the following structure: Water intake pump 7 has a power of 55kW and a flow rate of 1500m³ / h. When water intake pump 7 is started, water enters water intake pipe 6 through the trumpet-shaped water intake port 17 (diameter 2.5m, 304 stainless steel). The hydraulic acceleration through the trumpet-shaped water intake port 17 increases the flow velocity from 0.3m / s to 2.5m / s. The high-speed water flow then enters the delivery pipe 19, with a spiral section length of 12m. Under the action of the spiral plate 21 with a pitch of 300mm, a turbulent field with a Reynolds number > 50000 is generated. The spiral plate 21 has a ceramic coating and a friction coefficient ≤ 0.05.

[0030] The spiral plate 21, through its hyperboloidal flow-guiding design, allows suspended solids in the water to migrate outwards in a mechanical environment with a centrifugal acceleration ≥15g, forming a stratified flow. Impurities such as silt and algae with a density >1.2g / cm³ move along the spiral groove (200mm wide) to the slag discharge pipe 18 and are discharged by the slag discharge valve. The permeable mesh 20 adopts a gradient pore size design, with an outer layer of 50μm wedge-shaped filter mesh, a middle layer of 10μm gradient density fiber layer, and an inner layer of 5μm ultrafiltration membrane. Through the three-stage synergy of "hydraulic centrifugation - gradient permeation - photochemical purification", the effluent turbidity can be ≤0.1NTU, the algae removal rate ≥99.7%, the E. coli inactivation rate >99.99%, and the comprehensive energy consumption ≤0.35kWh / m³, realizing an integrated operation of ecological high-purity water intake and purification.

[0031] Working principle: First, a flexible, physically floating protective barrier net 12 is installed 50 meters from the water intake of the reservoir body. This outermost layer of the barrier mainly collects and blocks oil and algae from the shallow water surface, at a depth of 1-3 meters. It is supported by a filter net 16 as a base. From the inside out, there are three layers: an inner layer, a middle layer, and an outer layer. Each layer includes several traction ropes 9. The outer wall of the traction ropes 9 is connected to buoys 10 for floating on the lake surface. The components are connected by an arc-shaped plate 11, and a gravity block 13 is installed at the lower end of the interception net 12. The purpose is to utilize the protective barrier surrounding the reservoir body 1 to effectively block surface algae and algae in the water, preventing them from entering the water intake and ensuring the safety of the water quality at the water source intake. Furthermore, the wind power is used to automatically collect algae, improving the protection of the water intake. Within the outer enclosure of the trumpet-shaped water intake 17, at a distance of 30-50 mm from the water intake... At a distance of 1 meter, a 3-5 meter wide base platform 3 is constructed using 10-50 cm diameter boulders. The structure includes foundation piles 4, on which a concrete platform 5 is fixed. The filtration mechanism above the concrete platform 5 includes filter screen 3 16, filter screen 2 15, and filter screen 1 14. Filter screen 3 16 has a pore size of less than 20 micrometers and is used to intercept larger suspended solids or impurities. Filter screen 2 15 typically has a filtration diameter of around 50 micrometers and further filters smaller particles or pollutants. Filter screen 1 14 can have a filtration diameter of 100 micrometers or more and is suitable for purifying pollutants in water containing larger suspended solids or organic matter. This effectively protects and improves the water supply safety of drinking water sources and upgrades water quality.

[0032] Finally, when water is drawn through the horn-shaped water inlet 17, the water pump installed at the water intake pipe 6 draws the water through the horn-shaped water inlet 17 to the delivery pipe 19. Under the spiral guidance of the spiral plate 21, the impurities in the delivery pipe 19 are moved outward by the centrifugal force of the spiral plate 21, and the clean water is drawn through the permeation net 20 to the water intake pipe 6 and then extracted, thus achieving the water purification work.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
