Description

Technical Field

[0001] This utility model relates to the technical field of pure water equipment maintenance, and in particular to an automatic flushing device for pure water equipment. Background Technology

[0002] Pure water equipment removes impurities such as suspended solids, colloids, dissolved salts, and microorganisms from raw water through multi-stage filtration processes such as pretreatment, reverse osmosis, and ultrafiltration, producing pure water that meets drinking or industrial standards. Its core components include reverse osmosis membranes, ultrafiltration membranes, and activated carbon filters.

[0003] During long-term operation, the membrane module surface of pure water equipment is prone to the formation of a fouling layer due to the deposition of pollutants, which can lead to problems such as increased filtration resistance, decreased water production, and reduced desalination rate. Regular flushing and maintenance are required.

[0004] In the existing technology, some pure water equipment typically uses a straight pipeline with no diversion design to discharge wastewater containing impurities during the rinsing process. This can easily cause solid impurities in the wastewater to mix with the sewage, resulting in local sludge accumulation and blockage in the sewage pipeline. This leads to an imbalance in rinsing pressure and poor sewage discharge, which in turn affects the cleaning effect of the membrane module and increases the burden of equipment operation and maintenance.

[0034] Example 1

[0035] Reference Figures 1 to 3 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0036] Frame 100;

[0037] A rinsing unit 200 is mounted on the frame 100 and is used to rinse the pure water equipment. A drain assembly 300 is mounted on the rinsing unit 200 and is used to discharge rinsing impurities.

[0038] Separation component 400 is disposed within sewage discharge component 300 and is used for solid-liquid separation of impurities.

[0039] In use, the flushing unit 200 integrates the flushing function, which facilitates installation, maintenance and overall equipment coordination, and avoids pollutant deposition affecting the quality of produced water. The sewage discharge component 300 is directly connected to the flushing unit 200 to ensure that the sewage containing impurities generated during flushing is quickly discharged to prevent secondary pollution. At the same time, the separation component 400 performs solid-liquid separation on the impurities in the sewage discharge, which can reduce the risk of pipe blockage, extend the life of core components and reduce the pressure on subsequent sewage treatment.

[0040] Example 2

[0041] Reference Figures 1 to 3 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0042] The flushing unit 200 includes multiple reverse osmosis membrane housings 201, which are fixedly connected to the frame 100 and arranged in sequence. A booster pump 202 is fixedly connected to the frame 100, and the output end of the booster pump 202 is fixedly connected to a flushing pipe 203. The flushing pipe 203 is fixedly connected to the multiple reverse osmosis membrane housings 201. An evaporator 204 is fixedly connected to the frame 100, and a connecting pipe 205 is fixedly connected to the evaporator 204. The connecting pipe 205 is fixedly connected to the booster pump 202.

[0043] The frame 100 integrates multiple reverse osmosis membrane housings 201, which are arranged in an orderly manner to improve space utilization and maintenance convenience. The evaporator 204 delivers the produced water to the booster pump 202 via the connecting pipe 205. After being pressurized, the water is evenly supplied to each membrane housing through the flushing pipe 203 to ensure stable flushing pressure. The integrated design reduces pipeline losses, improves flushing efficiency, effectively delays membrane fouling, and extends equipment life.

[0044] Specifically, the sewage discharge assembly 300 includes two sewage discharge pipes 301, which are fixedly connected to multiple reverse osmosis membrane housings 201 respectively. The bottom ends of the two sewage discharge pipes 301 are fixedly connected to a confluence pipe 302. A three-way valve 303 is fixedly connected to both confluence pipes 302. A hollow box 304 is fixedly connected to the three-way valve 303. A connecting pipe 305 is fixedly connected to the hollow box 304.

[0045] Wastewater from each membrane housing is collected simultaneously through the drain pipes 301 on both sides, improving the efficiency of wastewater discharge and preventing impurities from accumulating. The merging pipe 302 facilitates the collection of wastewater, and the flow direction is regulated by the three-way valve 303. The hollow box 304 provides a buffer space for subsequent separation. The through pipe 305 smoothly discharges the treated wastewater, reducing the risk of blockage and ensuring that flushing impurities are discharged quickly.

[0046] Specifically, the separation component 400 includes a rotating plate 401, which is rotatably connected to the inner wall of the hollow box 304, and a filter plate 402 is movably disposed inside the hollow box 304.

[0047] During use, the rotating plate 401 rotates within the hollow box 304 under the influence of flushing water, which can break up the aggregated impurities in the sewage, prevent local clogging of the filter plate 402, and simultaneously achieve solid-liquid separation, improve the impurity retention efficiency, and reduce the cleaning frequency of the filter plate 402.

[0048] Example 3

[0049] Reference Figures 1 to 3 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0050] Two positioning blocks 4021 are fixedly connected to the filter plate 402, and two clamping plates 4022 are rotatably connected to one side surface of the hollow box 304. Both clamping plates 4022 are engaged with the corresponding positioning blocks 4021.

[0051] The filter plate 402 is engaged with the clamping plate 4022 by the positioning block 4021, which facilitates quick disassembly of the filter plate 402 without tools. This ensures that the filter plate 402 is stable and does not shake, and also makes it easy to remove it for cleaning or replacement regularly, ensuring a long-lasting and stable filtration effect.

[0052] Specifically, pressure regulating valves 2031 are fixedly connected to the flushing pipe 203 and the two drain pipes 301.

[0053] The pressure regulating valve 2031 can control the internal pressure of the flushing pipe 203 and the drain pipe 301, so as to avoid damage to the membrane module or pipeline due to excessive pressure, and also to prevent insufficient pressure from causing incomplete flushing and poor drainage.

[0054] Specifically, the flushing pipe 203 is fixedly connected to two branch pipes 2032, each branch pipe 2032 is fixedly connected to a solenoid valve 2033, each branch pipe 2032 is fixedly connected to a U-shaped pipe 2034, and each U-shaped pipe 2034 is fixedly connected to a flow meter 2035.

[0055] The two side pipes 2032 can be equipped with solenoid valves 2033 to flexibly adjust the distribution of flushing water flow. The U-shaped pipe 2034 buffers water flow fluctuations to ensure stability. The flow meter 2035 monitors flow data in real time to achieve precise flow control, improve flushing efficiency, reduce water waste, and ensure uniform flushing effect for each membrane module.

[0056] Specifically, the bottom surface of the frame 100 is fixedly connected to multiple base plates 101, and each base plate 101 is provided with an anti-slip surface.

[0057] During use, the frame 100 is stably supported by multiple base plates 101 with anti-slip surfaces, which increases the friction between the frame and the ground, prevents the equipment from shifting or shaking due to vibration during operation, improves overall stability, ensures secure pipeline connections, and reduces the risk of failure.

[0058] During use, the frame 100 is stably supported by the base plate 101 with an anti-slip surface. The water to be treated produced by the evaporator 204 is transported to the booster pump 202 via the connecting pipe 205. After the booster pump 202 starts, it pressurizes the water flow. The pressurized water is distributed to multiple horizontally arranged reverse osmosis membrane housings 201 through the flushing pipe 203 to achieve the flushing operation of the membrane modules. The pressure regulating valve 2031 on the flushing pipe 203 can accurately control the inlet water pressure. The solenoid valves 2033 on the two branch pipes 2032 can switch on and off as needed. The U-shaped pipe 2034 buffers water flow fluctuations, and the flow meter... 2035 monitors the flow rate of each branch pipe 2032 in real time to ensure that the flushing intensity is stable and controllable. The wastewater containing impurities generated during flushing is discharged through two drain pipes 301 connected to the membrane housing assembly. The wastewater flows into the confluence pipe 302 through the drain pipe 301, and then enters the hollow box 304 through the three-way valve 303. The rotating plate 401 inside the hollow box 304 rotates with the water flow, initially breaking up the solid impurities in the wastewater. Then the water flows through the filter plate 402. The filter plate 402 is fixed by the engagement of the positioning block 4021 and the clamping plate 4022, which efficiently intercepts solid pollutants and completes solid-liquid separation. The separated wastewater is discharged through the connecting pipe 305.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
