Description

Technical Field

[0001] This utility model relates to the technical field of water source filtration, and in particular to a water source replenishment device with filtration function. Background Technology

[0002] In the field of water resource protection and utilization, water sources, as the core source of regional water supply, are directly related to the sustainable development of residents' lives, industrial production, and the ecological environment due to their stable water quantity and water quality safety. With the acceleration of urbanization and the frequent occurrence of extreme weather, problems such as declining water levels and insufficient water quantity in water sources are becoming increasingly prominent. Replenishing water resources to water sources through water replenishment equipment has become a key means to maintain the ecological function of water sources and ensure water supply capacity.

[0003] However, during the replenishment process of water sources, the replenished water often contains pollutants such as silt, suspended solids, and particulate matter. If directly injected into the water source, it will not only cause the water to become turbid and less transparent, but may also clog water intake facilities, affect the living environment of aquatic organisms, and even lead to the risk of the water quality exceeding standards. Therefore, effective filtration of the replenished water during the replenishment process has become a core requirement for ensuring the quality of water replenishment to water sources.

[0004] Currently, most water supply equipment for water sources on the market focuses on water delivery. Existing filtration structures mostly use a single filter screen, which can only remove large particulate impurities and has limited effect on filtering fine suspended solids, colloids and other pollutants, thus failing to meet the high precision requirements of water sources for water supply quality. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this utility model provides a water source replenishment device with filtration function.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a water source replenishment device with filtration function, comprising:

[0008] The filter cartridge has a filter chamber inside, and an inlet pipe and an outlet pipe are connected to the filter cartridge.

[0009] The filter assembly, located inside the filter cartridge, is used to filter the water source coming in from the inlet pipe;

[0010] The filtering components include:

[0011] The coarse filter plate is fixedly installed inside the filter cylinder and is positioned above the inlet pipe.

[0012] A water baffle plate is fixedly installed on the inner wall of the filter cylinder, and a filter element support plate is integrally set on the water baffle plate.

[0013] Multiple secondary filter elements are arranged and connected on a filter element support plate;

[0014] The baffle is fixedly installed on the inner wall of the filter cartridge to block the water flow and prevent the water from flowing directly into the outlet pipe.

[0015] Furthermore, an inspection port is provided at the top of the filter cartridge, an adjustment seat is provided on the outer wall of the inspection port, a swing rod is oscillating on the adjustment seat, a screw is vertically provided on the swing rod, a top cover is threaded onto the screw, and the top cover is installed on the inspection port.

[0016] Furthermore, a handle is provided on the top cover, and the handle is slidably sleeved on the screw.

[0017] Furthermore, an exhaust vent is provided on the top cover.

[0018] Furthermore, a hinged seat is provided on the inspection port of the filter cartridge, a pressure rod is oscillatingly mounted on the hinged seat, and an exhaust plug is slidably mounted on the pressure rod, with the exhaust plug slidably inserted into the exhaust hole.

[0019] Furthermore, the vent plug is equipped with an anti-detachment plate to prevent the vent plug from falling off the pressure rod.

[0020] Furthermore, a waste discharge port is connected to the bottom of the filter cartridge, and a drain cover is installed on the top of the waste discharge port.

[0021] Furthermore, control valves are installed on both the inlet and outlet pipes.

[0022] The water source replenishment device with filtration function provided by this utility model, as described above, has the following beneficial effects:

[0023] The coarse filter plate first intercepts large particles of impurities, preventing them from affecting subsequent fine filtration. Multiple secondary filter cartridges form a dense fine filtration unit, deeply purifying tiny pollutants. This dual filtration mechanism significantly improves filtration accuracy, ensuring that the replenishment water meets the strict requirements of the water source for transparency and pollutant content. This avoids the risk of turbidity in the water source, blockage of water intake facilities, and water quality exceeding standards caused by direct replenishment. The baffle plate divides the filtration chamber into different functional areas, guiding the water flow to pass through the secondary filter cartridges before entering subsequent stages. The baffle prevents water from flowing directly to the outlet pipe, forcing the filtered water to overflow and ensuring that every part of the water flow fully passes through the coarse and fine filtration processes. This completely eliminates water flow short-circuiting, ensures the stability of filtration efficiency, and prevents unfiltered water from directly entering the water source.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] See Figure 1-5 As shown;

[0033] The water source replenishment device with filtration function according to this embodiment of the utility model includes:

[0034] Filter cylinder 1, with a filter chamber inside the filter cylinder 1, and an inlet pipe 11 and an outlet pipe 12 connected to the filter cylinder 1.

[0035] The filter assembly is located inside the filter cylinder 1 and is used to filter the water source coming in from the water inlet pipe 11;

[0036] The filtering components include:

[0037] The coarse filter plate 21 is fixedly installed inside the filter cylinder 1 and is positioned above the water inlet pipe 11.

[0038] The water baffle plate 22 is fixedly installed on the inner wall of the filter cylinder 1, and the filter element support plate 23 is integrally provided on the water baffle plate 22;

[0039] Multiple secondary filter elements 24 are arranged and connected on the filter element support plate 23;

[0040] Baffle 25 is fixedly installed on the inner wall of filter cylinder 1 to block water flow and prevent water from flowing directly into the outlet pipe 12.

[0041] Water enters through the inlet pipe 11. As the water level inside the filter cartridge 1 rises, the water is initially filtered through the coarse filter plate 21. As the water level continues to rise, the water flows through the filter cartridge support plate 23 into each secondary filter cartridge 24, where it undergoes secondary filtration. After passing through the secondary filter cartridge 24, the filtered water flows through the secondary filter cartridge 24 into the gap between the baffle plate 22 and the filter cartridge 1. Due to the blocking effect of the baffle plate 25, the filtered water does not flow directly into the outlet pipe 12. Only when the water level reaches the opening of the outlet pipe 12 will the filtered water overflow, completing the filtration process.

[0042] By adopting the above technical solution, the replenishing water source enters the filtration chamber inside the equipment through the inlet pipe 11 connected to the filter cylinder 1. As the water level inside the filtration chamber gradually rises, the water flow first contacts the coarse filter plate 21 located above the inlet pipe 11. The coarse filter plate 21 is fixedly installed inside the filter cylinder 1, and its filter hole size is adapted to the interception requirements of large particles. It can quickly filter out pollutants such as silt and larger suspended solids contained in the water source, completing the preliminary purification and preventing large particles from entering the subsequent filtration stage and causing blockage. The water flow after preliminary filtration continues to rise, reaching the solids... The water is positioned at the water baffle 22 on the inner wall of the filter cartridge 1, and then flows through the filter plate 23 into multiple secondary filter elements 24 arranged on the filter plate 23. The secondary filter elements 24 use high-precision filter media, which can deeply intercept fine suspended solids, colloids and other micro-pollutants remaining after the initial filtration, achieving fine purification of the water source and significantly improving water purity. After being finely filtered by the secondary filter elements 24, the water flows through the filter elements into the gap between the water baffle 22 and the inner wall of the filter cartridge 1. Because a baffle 25 is fixedly installed on the inner wall of the filter cartridge 1, the water... The water flow is effectively blocked and cannot flow directly to the outlet pipe 12, but can only gradually accumulate in the gap. When the filtered water level in the gap rises to the position of the outlet pipe 12, the filtered water that meets the water quality requirements flows into the outlet pipe 12 through overflow and is finally transported to the water source, completing the entire filtration process. The coarse filter plate 21 first intercepts large particles of impurities to prevent them from affecting the subsequent fine filtration. Multiple secondary filter cartridges 24 form a dense fine filtration unit to deeply purify tiny pollutants. The dual filtration mechanism greatly improves the filtration accuracy, making the makeup water quality meet the requirements of the water source. Strict requirements on water transparency and pollutant content are imposed to avoid the risk of turbidity in the water source, blockage of water intake facilities, and water quality exceeding standards caused by direct water replenishment. The baffle plate 22 divides the filtration chamber into different functional areas, guiding the water flow to pass through the secondary filter element 24 before entering the subsequent stages. The baffle plate 25 blocks the water flow from flowing directly to the outlet pipe 12, forcing the filtered water to be discharged through overflow, ensuring that each part of the water flow can fully pass through the coarse and fine filtration processes, completely eliminating the phenomenon of water flow short circuit, ensuring the stability of filtration efficiency, and preventing unfiltered water from directly entering the water source.

[0043] As a preferred embodiment of the above technical solution, such as Figures 4 to 5 As shown, the filter cylinder 1 has an inspection port at the top, an adjustment seat 13 is provided on the outer wall of the inspection port, an adjustment rod 14 is oscillatingly provided on the adjustment seat 13, a screw 15 is vertically provided on the oscillating rod 14, a top cover 16 is threaded onto the screw 15, and the top cover 16 is installed on the inspection port.

[0044] In this embodiment, when it is necessary to clean, replace, or repair the filter components such as the coarse filter plate 21 and the secondary filter element 24 inside the filter cartridge, the top cover 16 is rotated to move upward along the vertical direction of the screw 15, gradually disengaging from the sealed contact with the inspection port of the filter cartridge 1, thus releasing the closed state of the inspection port. After the top cover 16 rises to a sufficient height, since the swing rod 14 is oscillatingly connected to the adjusting seat 13 on the outer wall of the inspection port, the operator can push the swing rod 14 to swing horizontally around the hinge point of the adjusting seat 13. At this time, the swing rod... The vertically connected screw 15 and the top cover 16 mounted on the screw will move synchronously with the swing rod, eventually moving the top cover 16 from directly above the access port to the side or other positions that do not affect the maintenance operation, fully exposing the access port and providing operating space for subsequent maintenance of internal components; the sealing can be unlocked and closed by rotating the top cover without disassembling complex parts; the design of the swing rod can quickly move the top cover to the side, eliminating the need to store the top cover separately, and allowing a single person to complete the opening and closing of the access port, greatly shortening maintenance time and reducing the difficulty of field operations.

[0045] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, a handle 17 is provided on the top cover 16, and the handle 17 is slidably sleeved on the screw 15;

[0046] In this embodiment, the handle 17 provides a stable gripping area for the operator, making it easy for the operator to rotate the top cover 16 without the need for additional tools. This is suitable for operation scenarios in the wild where there is no electricity or special tools, thus improving the efficiency of maintenance operations.

[0047] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, an exhaust port 18 is provided on the top cover 16;

[0048] In this embodiment, the vent 18 can discharge the air inside the cavity in real time, completely eliminating air resistance, ensuring that the water flow can rise smoothly and pass through the staged filtration in sequence, maintaining stable filtration efficiency, avoiding the problem of reduced water delivery capacity of the water supply equipment and interruption of the filtration process due to air resistance, and ensuring the continuity of water supply to the water source.

[0049] As a preferred embodiment of the above technical solution, such as Figures 4 to 5As shown, a hinge seat 1a is provided on the inspection port of the filter cartridge 1, a pressure rod 1b is oscillatingly provided on the hinge seat 1a, and an exhaust plug 1c is slidably provided on the pressure rod 1b. The exhaust plug 1c is slidably inserted into the exhaust hole 18.

[0050] In this embodiment, when the equipment is started and enters the normal filtration process, the air in the filter chamber needs to be discharged through the exhaust port 18. At this time, the operator can swing the pressure rod 1b connected to the hinge seat 1a upward. Since the pressure rod 1b and the hinge seat 1a are oscillatingly connected, the pressure rod will rotate upward around the hinge point, causing the exhaust plug 1c, which is slidably set on the pressure rod, to move upward synchronously. As the pressure rod continues to swing upward, the exhaust plug 1c is gradually pulled out from the inserted exhaust port 18, and finally completely disengages from the channel of the exhaust port 18, so that the exhaust port 18 is in a fully open state. If the equipment is running... In the event of severe weather such as heavy rain or strong winds, rainwater or dust may enter the filter chamber through the open vent 18 and contaminate the water. At this time, the operator can quickly press down the pressure rod 1b, which swings downward around the hinge seat 1a, causing the vent plug 1c to move vertically downward until the vent plug 1c slides back into the vent hole 18. Since the vent plug 1c and the vent hole 18 are a matching sliding fit structure, the vent plug can completely seal the passage of the vent hole 18 after insertion, preventing external rainwater and impurities from entering, while also preventing the water in the filter chamber from overflowing from the vent hole due to changes in air pressure.

[0051] As a preferred embodiment of the above technical solution, an anti-detachment plate is provided on the exhaust plug 1c, which is used to prevent the exhaust plug 1c from falling off the pressure rod 1b.

[0052] In this embodiment, the exhaust plug 1c and the pressure rod 1b are only in a simple sliding fit. During field operations, if the operator does not reset the exhaust plug in time after opening it, or if the pressure rod swings violently due to strong winds or collisions, the exhaust plug is very likely to slip off the pressure rod and be lost. The anti-detachment plate ensures that the exhaust plug is always connected to the pressure rod through physical limiting, which can ensure the integrity of the equipment's exhaust and sealing functions and avoid the overall equipment from stopping due to the loss of small parts.

[0053] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, a waste discharge port is connected to the bottom of the filter cylinder 1, and a drain cover 19 is installed on the top of the waste discharge port;

[0054] In this embodiment, if the existing water source replenishment equipment does not have a bottom waste outlet, the silt and large particles of impurities intercepted by the coarse filter plate 21 during the filtration process will continue to accumulate at the bottom of the filter cylinder, gradually clogging the filter holes of the coarse filter plate 21, causing the water flow to be unable to rise smoothly to the secondary filter element 24; the waste outlet and the drain cover 19 can periodically and thoroughly remove the impurities at the bottom, avoid clogging the filter holes of the coarse filter plate 21, ensure that the water flow can smoothly pass through the coarse filter plate and enter the secondary filter element 24, and ensure that the equipment meets the high precision requirements of the water source for replenishment water quality for a long time.

[0055] As a preferred embodiment of the above technical solution, control valves are connected to both the inlet pipe 11 and the outlet pipe 12;

[0056] In this embodiment, the control valve adjusts the inlet water flow to ensure a steady rise in water flow, allowing the coarse filter plate and the secondary filter element to function fully in sequence; by matching the outlet water flow, the water level is maintained to ensure that the quality of the replenished water meets the high-precision requirements of the water source.

[0057] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
