[0028] In order to make the purpose, technical scheme and advantage of the embodiments of the present disclosure more clear and obvious, the embodiments of the present disclosure are further described in detail below with reference to the embodiments and drawings, and the schematic embodiments of the embodiments of the present disclosure and the description thereof are only used to explain the embodiments of the present disclosure, and do not limit the embodiments of the present disclosure.

[0029] As Figure 1 shown, the reverse osmosis equipment operation energy-saving device of the present application includes a water storage tank 1, a high-pressure pump 2, a reverse osmosis membrane assembly 3, a drain pipe 4 and a collection tank 5.

[0030] The water storage tank 1 is installed at the front end of the system and is responsible for storing raw water before entering the system. The water storage tank 1 has sufficient capacity to ensure that the water required for the reverse osmosis process can be stably supplied, and has good sealing performance to prevent water evaporation or be affected by external pollutants.

[0031] The high-pressure pump 2 is directly connected with the water storage tank 1 and is adjacent to the rear thereof, and is responsible for pressurizing the raw water stored in the water storage tank 1 to an appropriate pressure value and then delivering it to the subsequent processing link, i.e., the reverse osmosis membrane assembly 3. This high-pressure pump 2 is driven by a motor and can adjust the output pressure according to the process requirements, and provides stable water flow pressure in the entire operation process, which guarantees the effectiveness and continuity of the processing process.

[0032] The reverse osmosis membrane assembly 3 is located at the central position of the device and is connected with the high-pressure pump 2 for performing the core reverse osmosis separation operation to remove the dissolved solid substances in the water. The assembly is internally provided with multiple layers of high-precision filter core materials, forming a dense structure to allow the treated pure water to flow through while blocking harmful impurities such as salt. In the working state, the concentrated solution retained is discharged through a drain pipe installed at one end.

[0033] The device is also provided with a drain pipe 4 specially used for collecting the concentrated liquid, i.e., the concentrated water discharge. The part of waste liquid from the reverse osmosis membrane assembly 3 is led out of the system through an independent pipeline, avoiding the return of non-standard water quality into the system to pollute the pure product and reducing the difficulty of secondary utilization of water resources.

[0034] The last link is a pure water collection tank 5 for storing the purified product, which is placed at the end of the whole system. The high-quality clean water obtained in the reverse osmosis process will flow along the fixed path into the tank, and when the storage reaches a certain amount, it can be taken out to supply other water departments or further processing steps.

[0035] In one embodiment, referring to Figure 2 , the water storage tank 1 of the reverse osmosis device energy-saving device of the present application is located below the high-pressure pump 2 and is connected to the high-pressure pump 2 by a vertically upward extending pipe 7. The purpose of this design is to allow the raw water to flow into the high-pressure pump 2 by its own gravity, thereby reducing the supply and consumption of external energy.

[0036] That is, in the present application, the pipe is installed in a vertical direction to ensure that the water flows from bottom to top and can naturally rely on the static pressure head stored in the water storage tank 1 before entering the high-pressure pump 2. This vertical installation ensures that the water can flow automatically under the action of gravity without relying on additional power to start the preliminary water inlet process of the pump, thereby effectively reducing energy consumption. In addition, appropriate sealing measures are taken at the connection between the pipe and the high-pressure pump 2 to ensure that there is no leakage or other adverse conditions during the water flow process, thereby maintaining the stability of the entire system.

[0037] Specifically, for example, the water storage tank 1 is designed to have sufficient volume to meet the water supply required for the continuous operation of the high-pressure pump 2, while ensuring that the height difference is suitable for gravity flow. In the actual assembly process, the water storage tank 1 is first fixed and installed at a position lower than the high-pressure pump 2, and then the vertically upward connecting pipe is matched and installed to the high-pressure pump 2, and finally the interfaces are adjusted to achieve a tight combination.

[0038] In one embodiment, continuing to refer to Figure 2 , the water storage tank 1 of the reverse osmosis device energy-saving device of the present application is provided with a plurality of evenly distributed support feet 8 at the bottom to ensure that the water storage tank 1 can be placed stably. The specific arrangement of the support feet 8 takes into account different ground flatness conditions, and the design height can be flexibly adjusted, thereby effectively ensuring the stability of the entire water storage tank 1 in actual installation and use. The support feet 8 are located at the outer side of the bottom end of the water storage tank 1 and are arranged in a surrounding manner to achieve the best balance. These structural members are in close contact with the bottom end surface of the water storage tank 1 to avoid the risk of shaking or tilting during use, and have good applicability to different types of placement sites.

[0039] Specifically, the support leg 8 adopts a split screw adjusting mechanism, which is composed of an upper fixing plate, a connecting column and an adjustable base. The connecting column is in an extension structure and is provided with a locking part to stabilize the set length. When facing a non-flat base or a special environment, the overall extension amount can be adjusted by manually rotating the adjustable base at the lower end to compensate for the height difference and maintain the horizontal center of gravity of the device.

[0040] For example, in some specific industrial environments, if a slightly uneven concrete floor is encountered, the user only needs to individually rotate the hand wheel at the end of the corresponding support leg 8 according to the actual needs of each support point until the entire device is in the ideal stationary state. At this time, all support components can stably contact the ground and evenly disperse the pressure, thereby avoiding negative effects on system operation. In addition, considering the aspect of moving convenience, this adjustable support leg 8 can also allow quick disassembly for transportation without affecting the working state of other functional components.

[0041] In one embodiment, the connecting pipe of the energy-saving device of the reverse osmosis equipment of the present application is internally provided with a smooth inner lining 9 (see Figure 2 ). The inner lining 9 is arranged in the connecting pipe between the high-pressure pump 2 and the water storage tank 1 and is constructed by using a specific low-friction material. The inner lining 9 closely adheres to the inner wall of the pipe and extends from the pipe inlet to the pipe outlet, seamlessly covering the part through which the raw water flows.

[0042] The design of this inner lining 9 is to minimize the damping of the raw water flowing through the pipe. The selection of low-friction material can significantly reduce the resistance caused by surface roughness compared to traditional materials, improving fluid transmission efficiency. The pipe is designed with sufficient space for the inner lining 9 to ensure that it does not affect the original architectural layout of the entire system while achieving optimization goals.

[0043] Specifically, during the manufacturing stage, the pre-formed inner lining 9 can be fitted into the openings at both ends of the connecting pipe, and special techniques can be used to ensure that it closely adheres to the pipe wall without gaps; in addition, low-friction material can also be directly applied to the surface of the specified area by coating, and after the material is hardened, an effective inner protective structure is naturally formed to reduce mechanical energy consumption during the flow process. For example, it can be fixed and installed through special spraying processes or adhesives, thereby improving overall performance without affecting the functions of other components.

[0044] In one embodiment, as shown in FIG. 3, the reverse osmosis device operating energy saving device of the present application is characterized in that the reverse osmosis membrane assembly 3 comprises multiple layers of parallel arranged reverse osmosis membranes 10. Reasonable gaps are left between each layer of membranes to ensure smooth water flow channels, thereby ensuring that raw water uniformly permeates through each layer of membranes under pressure. In this way, while effectively removing dissolved substances and impurities in water, the additional energy consumption caused by path resistance of water flow is reduced, and energy efficiency is improved. The above-mentioned features are designed ingeniously to optimize device performance and reduce operating costs.

[0045] For example, the device can achieve this multi-layer and parallel arrangement by installing multiple sets of support partitions. Each support partition is responsible for separating one or more layers of reverse osmosis membranes 10 and keeping them at a consistent and small distance from each other, which can ensure sufficient water contact area and minimize unnecessary frictional resistance when water flows through. Specifically, these support partitions are vertically arranged on the inner side walls of the reverse osmosis membrane assembly 3 and are in contact with the end caps for fixation, thereby forming a series of closed or semi-closed chambers for the placement of reverse osmosis membranes 10.

[0046] In addition, considering the water flow characteristics and pressure distribution, the device also has an adjustment module for precisely controlling the water pressure level before entering the reverse osmosis assembly, so that the optimal operating parameter settings can be adapted at different time periods or working conditions. This function ensures that the working state of each region inside the device can reach a better balance state regardless of whether the external water supply is stable, providing technical support for the energy-saving operation of the entire device.

[0047] In one embodiment, the connecting pipeline between the reverse osmosis membrane assembly 3 and the collection tank 5 of the reverse osmosis device operating energy saving device of the present application is designed as a U-shaped bend. This design not only shortens the length of the flow channel, but also avoids the use of right-angle bends, thereby effectively reducing the local water flow resistance caused by sharp turns. The device directly introduces a U-shaped bend with a unique structure into the downstream of the reverse osmosis membrane assembly 3 to connect the collection tank 5, ensuring that the water flow can flow more smoothly from the membrane assembly into the collection tank 5, and this special bend structure can reduce energy loss in physical structure.

[0048] On the basis of the existing, the connection form is optimized to reduce the problem of water dynamic performance decline caused by path turning. Specific measures include selecting a design scheme with a more gentle radius and meeting the requirements of fluid mechanics to ensure that the liquid does not form vortex or stagnation area due to excessive turning. In addition, in order to ensure the stability and efficiency of the system, sufficient attention is also given to the selection of manufacturing materials and the smoothness of the internal surface to further enhance the fluid transmission efficiency.

[0049] For example, during installation, a pre-fabricated U-shaped bend can be placed in the designated position, with one end tightly connected to the outlet of the reverse osmosis membrane module 3, and the other end extending and precisely aligned with the inlet of the downstream collection tank 5. Ensure the connection between the two pipe sections is tightly sealed and leak-free, while maintaining the structural integrity of the U-shaped pipe itself without deformation. Furthermore, select pipe materials with pressure resistance and corrosion resistance to meet the requirements of the actual operating environment and ensure long-term stable operation of the device.

[0050] In one embodiment, such as Figure 4 As shown, the drain pipe 4 of the reverse osmosis equipment energy-saving device of this application uses a tapered pipe 12 instead of a traditional straight pipe. This drain pipe 4 is characterized by its gradually increasing diameter, which gradually reduces the cross-sectional flow velocity when concentrated water is discharged, thus reducing the impact and friction on the pipe wall. In this way, the system can significantly reduce the internal frictional resistance of the pipe, thereby improving the overall energy utilization efficiency.

[0051] For example, this can be accomplished by installing a pipe that gradually widens from the reverse osmosis membrane module 3 to the outlet 15. The innovation of this design lies in the unique configuration of the conical section, which is not limited to a fixed angle of inclination. In practical applications, to ensure a smooth water flow transition and minimize pressure drop, the drain pipe 4 needs to be precisely positioned after the reverse osmosis membrane module 3, separate from the collection tank 5. Furthermore, considering different site environment requirements and user needs, conical structures with different opening ratios and length variation rates can be customized for specific operating conditions.

[0052] For example, in a specific application scenario, the drain pipe 4 in this energy-saving device gradually expands from near the reverse osmosis membrane module 3 to a wider diameter until it reaches the complete discharge port. This ensures low flow resistance throughout the discharge process, simplifies system maintenance, and enhances the overall stability and lifespan of the equipment. With this structure, concentrate can be drawn out of the system more slowly and continuously without causing significant pressure fluctuations or unnecessary energy loss.

[0053] Return to reference Figure 2 In one embodiment, the collection tank 5 of the reverse osmosis equipment energy-saving device of this application is provided with multiple longitudinally distributed guide plates 13. These guide plates 13 are installed inside the collection tank 5, uniformly distributed longitudinally and arranged parallel to each other. The purpose of the guide plates 13 is to effectively guide the pure water treated by the reverse osmosis membrane module 3 to the bottom outlet of the tank, thereby minimizing the unnecessary energy consumption of the water flow during movement. In particular, all components in direct contact with the liquid, such as the guide plates 13, have undergone surface treatment to ensure that their outer surfaces are smooth.

[0054] Specifically, in the manufacturing process, the material with good wear resistance and corrosion resistance can be selected to make the guide plate 13, and it is finely polished to ensure the absolute smoothness of its surface. Then the guide plate 13 is inclined at a predetermined angle, which not only enables the water to flow smoothly along the specified path into the next system, but also facilitates the smooth discharge of waste water and impurities during cleaning, without causing residual or clogging. For example, the guide plate 13 can be stably connected to the two side walls of the collection tank 5 by screw fastening or other suitable means, maintaining the stability and integrity of the entire structure. In this way, the requirements of the description of the characteristics of the device regarding the internal configuration optimization are realized, which not only improves the operation efficiency but also guarantees the long-term stable operation requirements.

[0055] In one embodiment, a spiral flow channel 14 is provided in the connecting pipe between the high-pressure pump 2 of the energy-saving device of the reverse osmosis equipment and the reverse osmosis membrane module 3. The spiral flow channel 14 is installed in the internal space of the connecting pipe, and its shape presents a spiral structure. The special geometry of the spiral flow channel 14 can guide the fluid to form a stable vortex flow pattern inside the pipe. Through this unique design, the water flow generates a continuous vortex effect during transportation, effectively reducing the local flow resistance and laminar boundary thickness. This vortex effect significantly optimizes the velocity distribution of the water flow before passing through the reverse osmosis membrane module 3, making the flow state of the incoming water more stable and uniform.

[0056] Specifically, the spiral flow channel 14 is not a simple straight channel, but is composed of a series of guide vanes arranged along the axis in a spiral manner. These guide vanes are continuously distributed in the entire flow channel and gradually guide the water flow to move in a spiral manner. In order to ensure that the spiral effect can be maintained throughout the water transportation process, the angle and spacing of the guide vanes are precisely calculated and designed. In addition, the guide vanes are made of high-strength wear-resistant materials, which not only have corrosion resistance to adapt to various water qualities, but also have smooth surfaces to further reduce the friction coefficient. For example, in actual application, the high-pressure pump 2 accelerates the push of raw water into the reverse osmosis membrane module 3 through the spiral flow channel 14. Due to the existence of the vortex effect, the raw water exhibits lower resistance characteristics when flowing through the reverse osmosis membrane 10, thereby enhancing the operation efficiency of the water treatment system.

[0057] In one embodiment, the reverse osmosis device operating energy saving device of the present application is characterized by optimizing the positional relationship between the reverse osmosis membrane module 3 and the high-pressure pump 2 and the collection tank 5. By arranging the high-pressure pump 2 close to the reverse osmosis membrane module 3, the raw water output by the high-pressure pump 2 can quickly enter the reverse osmosis membrane module 3 via the shortest path, while the distance from the reverse osmosis membrane module 3 to the collection tank 5 is relatively long. This layout ensures that the delivery path from the high-pressure pump 2 to the reverse osmosis membrane module 3 is the shortest, thereby effectively reducing frictional losses in the water flow path. The compact design between components not only simplifies the overall structure of the device, but also reduces the energy consumption of the system.

[0058] In terms of specific design, this positional optimization can be achieved in various ways. For example, in the planar arrangement of the device, the high-pressure pump 2 can be installed next to one side of the reverse osmosis membrane module 3, while the collection tank 5 is placed at a relatively distant position. In order to ensure the shortest and smoothest flow path, a straight pipeline 6 with an appropriate diameter is connected between them. In addition, in order to improve the overall layout compactness, integrated pipeline design is adopted for the connecting components, and the bending section of the pipeline is shortened as much as possible to further reduce the resistance during flow.

[0059] The above design ensures that the pressurization kinetic energy provided by the high-pressure pump 2 is maximized to propel the water flow through the reverse osmosis membrane module 3, rather than being consumed in a long or complex pipeline system, thereby improving the energy efficiency and stability of the system. This compact pipeline arrangement not only simplifies maintenance work, but also helps to improve the reliability of the system and prolong the service life of the device. Specifically, by precisely selecting and optimizing the relative distances between components and their connecting pipelines, unnecessary energy loss can be significantly reduced.

[0060] In one embodiment, the collection tank 5 of the reverse osmosis device operating energy saving device of the present application is provided with a plurality of uniformly distributed discharge outlets 15, each equipped with an automatic regulating valve 16. The discharge outlets 15 are distributed in the bottom area of the collection tank 5 to ensure that pure water can be discharged in multiple directions, improving the uniformity of the drainage process. Each discharge outlet 15 is equipped with an independent automatic regulating valve 16, which monitors flow changes and adjusts the opening degree of each valve in a timely manner through an automatic control system, to maintain the stability of the water flow speed and the consistency of the flow path. This multi-point arrangement design can effectively reduce the frictional losses caused by uneven flow during the drainage process.

[0061] The automatic regulating valve 16 is a key component of the entire design, which is specifically composed of an actuator, a valve body and a controller. The controller determines the required opening or closing degree according to the preset parameters and the data returned by the sensor. When the flow increases, the controller transmits signals to each actuator to drive the valve to gradually increase the opening degree, so that the water flow can flow in a wider and smoother path; when the flow decreases, the opening degree is correspondingly reduced to maintain system stability and efficiency. In addition, the installation between the valve and the collection tank 5 adopts a modular design scheme, which is convenient for later maintenance and replacement.

[0062] For example, the automatic regulating valve 16 can respond to changes in flow demand in real time. When detecting changes in flow, the flow sensor located at the discharge port 15 will immediately send data to the controller. According to the received data, the controller will calculate the required valve opening degree and transmit it to each automatic regulating valve 16 through electrical signals or pneumatic means. This ensures that the optimal working state is always maintained within the entire working range, and significantly reduces energy loss caused by sudden narrowing of the flow path.

[0063] In one embodiment, the reverse osmosis device of the present application is provided with a protective shell 17 outside the reverse osmosis membrane assembly 3 of the energy-saving device, which is installed outside the reverse osmosis membrane assembly 3 and made of high-thermal-conductivity material, aiming to help the device dissipate heat better. By using high-quality thermal conductive material, the protective shell 17 can not only effectively reduce the influence of external high temperature on the reverse osmosis membrane assembly 3, but also prevent the assembly from being affected in performance and service life due to excessive heat generated during work. In order to further optimize the heat dissipation effect, a certain space gap is intentionally reserved between the protective shell 17 and the reverse osmosis membrane assembly 3, which ensures the smooth circulation of air and reduces the problems that may be caused by heat accumulation inside the assembly.

[0064] Specifically, when the device is used in a high-temperature environment, the heat in the surrounding environment will be quickly conducted and dissipated by the thermal conductive material, thereby avoiding the direct effect of excessive temperature on the surface or internal structure of the reverse osmosis membrane assembly 3. In addition, since the gap between the two is a layer of free air, it can carry away part of the heat energy dissipated by the reverse osmosis membrane assembly 3 under the action of natural convection. For example, in a specific embodiment, the protective shell 17 can be realized by processing aluminum or copper materials with high thermal conductivity into thin plates that conform to the shape of the membrane assembly, achieving efficient, stable and durable installation, and thus ensuring the energy-saving operation of the entire system.

[0065] Through this unique structural design, the overall heat dissipation capacity of the device can be significantly improved, and it can ensure normal operation in a wider temperature range, meeting the needs of different practical application scenarios. In the actual manufacturing process, the specific parameters of the protective shell 17 can be adjusted to match the optimal working state according to different sizes and models of reverse osmosis membrane assemblies 3. This includes not only the reasonable selection of materials for making the protective shell 17, but also fully considering factors such as the size and position of the reserved gap to ensure its optimal performance in actual application.

[0066] In actual operation, when the device is in use, the raw water before reverse osmosis is first stored in the water storage tank 1. Then, the raw water is extracted from the water storage tank 1 by the high-pressure pump 2 and delivered to the reverse osmosis membrane assembly 3. The reverse osmosis membrane assembly 3 filters the pressurized raw water to remove impurities and dissolved solids, generating pure water and concentrated water. The pure water is directly collected into the collection tank 5, while the concentrated water is discharged from the system through the drain pipe 4. The components are connected by compact straight pipelines 6, ensuring the shortest flow path length, thereby reducing water flow friction loss and improving overall energy efficiency. During the entire process, all operations are automatically and continuously performed without human intervention, effectively ensuring the efficient operation of the system.
