Description

Technical Field

[0001] The present invention generally relates to the circulation of fluid to an elevated container, and more specifically to a system and method for circulating fluid to an elevated container in a resistance-free manner using at least one fluid source container, at least one closed container for circulation, at least one elevated fluid container, at least one circulation mechanism for circulation purposes, and at least one start-stop mechanism for circulation control purposes. Background Technology

[0002] From the perspective of existing technology, one should mention the conventional circulation using pumps, in which pumps deliver fluid from a source container to another container, with fluid flowing from the source container into the end container in an additive manner until the existing fluid in the end container is replaced by the source fluid.

[0003] One approach describes the source fluid as the ocean, designed to contain marine animals and circulate naturally through a permeable net. This approach can also take the form of a sea-based container with semi-permeable or impermeable walls, where circulation is maintained by some form of circulation mechanism.

[0004] The most significant change in the method is the elevation of the container on land, where the circulation mechanism requires energy to transport the fluid to the elevated position. This necessitates that the circulation mechanism acquire sufficient energy to overcome hydrostatic pressure and the weight of the fluid by moving the water to the elevated position.

[0005] These methods are known as conventional fluid circulation methods, and their purpose is to displace the fluid in a container.

[0006] The main problems with fluid circulation to an elevated position are: 1. When moving a fluid to a higher position, the fluid needs a circulation mechanism to obtain enough energy to overcome the hydrostatic pressure and weight of the liquid; 2. Fluid circulation must be high. For example, marine organism containers require large amounts of water because each cubic meter of water contains seafood. Higher volumes will require greater power or lower flow resistance; 3. Liquid circulation requires high altitude. For fluid containers with marine animals or plants growing on a horizontally elevated plane, energy consumption must be low and the altitude must be high.

[0007] For example, in the seafood industry, circulating fluids to elevated positions solves many problems; the direct consequences of inefficient circulation are: 1. There is no need to transport marine animal feed by ship; 2. Seabed pollution caused by excrement will be easier to treat in land-based containers; 3. Anaerobic conditions caused by pollutants, excrement, and marine animal populations are easier to manage in closed and controlled environments; 4. Since the containers for marine animals can be land-based, there is no need to transport the products to market by ship; 5. High energy utilization of the water purification system; 6. The production of marine animals and the growth of urban plants will be more likely to increase in cities.

[0013] The problem this invention aims to solve: The problems listed below relate to all known methods of circulating liquids at elevated heights.

[0014] hydrostatic pressure and fluid weight If fluids flow naturally, elevation typically creates a downward flow. Due to gravity, water naturally flows from raised dams into the sea.

[0015] When upward flow occurs, the flow can be considered a resistance flow, where force is applied to the fluid's motion in a manner opposite to gravity. Water has a density of approximately 1 gram per cubic centimeter, and force is used to move water to any given elevation. The old definition of horsepower indicates that lifting one cubic meter at a rate of one meter per second would require a significant amount of energy. When moving water to an elevated location, removing resistance flow is crucial for energy efficiency.

[0016] Problem Solving Methods According to the present invention, the objective is achieved by: a system for circulating fluid to an elevated height; and a method for circulating fluid to an elevated height.

[0017] The present invention uses multiple operations of at least one circulation unit to circulate fluid to an elevated height, thereby achieving the above-mentioned objective.

[0018] Effects of the present invention The technical difference from traditional circulation methods is that at least one circulation unit can circulate fluid into the elevated container in a resistance-free manner, improving energy efficiency.

[0019] These effects also provide several other beneficial consequences: • The number of loop units can be increased, thereby increasing the loop flow. • Specific loop units can be used for specific loop tasks. • A specific circulation unit can be used for a specific fluid with different components. • The height of the circulating container can be increased with improved efficiency. • Due to the increased efficiency, overall noise can be significantly reduced.

[0038] the term Exemplary embodiments of the invention are described in conjunction with terminology to illustrate numerous alternatives, modifications, and equivalents that may be derived from the exemplary embodiments.

[0039] • Cyclic movement includes: all forms of motion or flow in the material within a loop, where the constituent particles are constantly changing position. • Circulation mechanisms include all forms of mechanisms that make circulation possible. In some implementations, the term "circulation device" refers to a circulation mechanism.

[0040] • Flow includes: all forms of particles in matter that continuously change position along a path. • Containers encompass all methods of containing substances • Elevated containers include all methods for containing substances at an elevated position above zero reference point. • Fluids include: all forms of matter having particles that can easily move and change their relative positions without separating the matter. • Start-stop mechanisms include all forms of mechanisms that prevent or allow substances to pass through. In some implementations, the term "valve" refers to a start-stop mechanism.

[0041] • A loop includes all forms of paths or routes located in space between two or more points. • Conveyors include all forms of loops used for transporting materials along a loop. • Maximum altitude limit is the altitude at which fluid in a closed container begins to flow in a downward motion, limited by equipment or physical laws. • A resistance-free cycle is a cycle in which the constituent particles of the material in the loop are not affected by the resistance of gravity. • A resistance cycle is a cycle in which the constituent particles of a substance in a loop are affected by the resistance of gravity. • A cycle unit refers to Figure 1 The invention and principles that form the basis of this invention In this invention, friction is considered negligible. Friction in the conveyor (pipe) is related to the thickness of the conveyor; for very thick conveyors (pipes), friction is close to zero and can be ignored. The term "resistance-free" is used to emphasize that this invention "eliminates" most of the resistance effects from gravity. The term "thickness" or "thickness" can refer to the hydraulic diameter of the conveyor (pipe).

[0042] The principles that form the basis of this invention The invention will be further described in conjunction with exemplary embodiments schematically illustrated in the figures.

[0043] To simplify the exemplary implementation, water (seawater) is used as the fluid. Similarly, friction in the circulation is neglected as resistance to flow because it is small compared to gravity. Friction in the pipe is related to the pipe thickness; for very thick pipes, friction is close to zero and can be ignored. Throughout the specification, all start / stop mechanisms are designated as valves (ball valves), and all circulation conveyors are designated as pipes. These mechanisms are most common in circulation systems and are schematically shown in the figures.

[0044] This invention utilizes the principle of generating hydrostatic systems. Pascal's law states that in a stationary encapsulated fluid, a pressure change at any point is transmitted undiminished to all points in the fluid. If the pressure changes within the circulation device at the conveyor inlet, it will produce the same pressure at the conveyor outlet.

[0045] A key characteristic is that the inlet and outlet are at the same level (pressure level). The principle that defines kinetic energy (in SI units, watts) states that energy will be used to generate motion, and if this motion is at the same level (height), energy will only be used to generate motion. Friction in motion is the only opposing force. If the motion of matter is not at the same level, energy is used to counteract gravity caused by the level difference. Energy can also be extracted from the level difference by using a siphon as a circulation device, where energy is consumed from the kinetic energy at the higher level.

[0046] When referring to the level, the depth below the container surface is not considered. If the depth of the conveyor inlet increases compared to the conveyor outlet, it will not affect the system. The pressure difference generated by the different fluid columns will uniformly offset the effect of the water column in the conveyor, and will not cause any flow.

[0047] However, gravity is significant, and if the conveyor inlet and outlet are at different surface levels, uneven pressure will occur. The water column will differ and begin to flow towards the lower level. This is a well-known principle; siphon.

[0048] If the conveyor inlet and outlet are at different levels, energy consumption can be increased to compensate for the pressure difference. A conventional centrifugal pump must generate a pumping pressure of 10,000 Pascals (0.1 bar) to move water upwards by 1 meter. This problem is solved by ensuring that the inlet and outlet are at the same hydrostatic pressure level, at the source surface, or at an elevated container surface.

[0049] Since the circulation unit does not add or remove fluid in the circulation, the only energy required is to establish the circulation (motion).

[0050] Initially, such as Figure 1 The system shown is filled with fluid. All start / stop mechanisms 13 and 14 are closed, and circulation devices 11 and 12 are stopped. In the example shown, start / stop mechanisms 13 and 14 cannot be opened simultaneously. If valve 13 is open and valve 14 is closed, the hydraulic system will be stationary, with no flow from container 2 to source container 1. Similarly, if valve 14 is open and valve 13 is closed, the hydraulic system will be stationary, with no flow from container 2 to the raised container 3. If both valves are open, the hydraulic system is not stationary, and fluid will flow from the raised container 3 to the source container 1.

[0051] By applying circulation through circulation device 11, a free-flowing circulation from the open source container 1 to the closed container 2 can be achieved when valve 13 is open and valve 14 is closed.

[0052] Similarly, when valve 13 is closed and valve 14 is open, the circulation device 12 circulates water from the closed container 2 to the raised container 3 in a resistance-free manner.

[0053] The basis of this invention is to solve the problems of hydrostatic pressure and fluid weight by introducing a resistance-free circulation.

[0054] Increase the circulation volume like Figure 2 The illustrated cyclic system solves the problem that arises when you need to increase flow through a resistance-free cycle.

[0055] Increasing the circulation volume into the raised container will increase energy consumption.

[0056] When fluids are transported to elevated containers, energy usage will increase by roughly the same factor by increasing the volume.

[0057] This problem is addressed by introducing multiple parallel-connected circulation units. These units allow for resistance-free circulation, and the efficiency gained can be multiplied by utilizing multiple parallel-connected units. Increasing the pipe diameter could also yield similar results, but this would limit the maximum elevation due to hydrostatic pressure and the weight of the water. The elevation gain might be more important than the pipe diameter.

[0058] This method will introduce flow in a resistance-free manner.

[0059] Increased altitude Figure 3 An efficient method for generating resistance-free fluid circulation is shown, in which altitude can be increased to an extreme level. This is achieved by multiple circulation units connected in series.

[0060] Because materials and equipment are limited when subjected to high pressure, hydrostatic pressure limits altitude.

[0061] This is usually solved by using high-pressure pumps and high-pressure equipment, but this method is a resistance cycle and inefficient.

[0062] By subdividing the pressure level into smaller elevations, a free-flowing circulation of fluid from the source container 35 to the elevated container 53 can be achieved, such as... Figure 3 As shown.

[0063] Figure 3 The circulation system shown solves the fluid circulation problem at extreme altitudes by using multiple circulation units connected in series.

[0064] Figure 1 A circulation unit is shown that circulates fluid from container 1 to closed container 2 when valve 13 is open and valve 14 is closed.

[0065] Once the circulation mechanism 11 has replaced the fluid in container 2 with fluid from source container 1, valve 14 is opened and valve 13 is closed. The circulation device 12 will then replace the contents of container 2 with fluid from the raised container 3.

[0066] As shown in the figure, the system is initially filled with fluid and all start / stop mechanisms 13 and 14 are closed, while circulation mechanisms 11 and 12 are stopped. Figure 1 In the example shown, valves 13 and 14 cannot be open simultaneously. If valve 13 is open and valve 14 is closed, the hydraulic system will be stationary, with no flow from container 2 to source container 1. Similarly, when valve 13 is closed and valve 14 is open, the hydraulic system will be stationary, with no flow from container 2 to the raised container 3.

[0067] Due to physical limitations imposed by the equipment and the laws of physics, the hydrostatic pressure generated by container 2 and pipe 4 will limit the maximum altitude. This limit is designated as the "maximum altitude limit," where the hydraulic system is not stationary and the fluid begins to flow in a downward motion. This limit may vary for different fluids or under different operating conditions.

[0068] Figure 1A This is a detailed diagram of the axial thruster pump motor 11. The circulation mechanism enables circulation between container 2 and container 1. Circulation replaces the fluid in container 2 with fluid from open container 1 through input pipe 9 (7) and outputs the fluid through pipe 10 (6). Similarly, circulation device 12 enables circulation between container 2 and container 3 in pipe 5.

[0069] If valve 13 opens and circulation mechanism 11 is activated, fluid will circulate between open container 1 and closed container 2. The hydraulic system is initially at rest, and the circulation mechanism generates pressure changes that are transmitted to all points in the fluid without attenuation. Low-pressure circulation is energy-efficient.

[0070] Figure 1B This is a detailed illustration of a discharge device 16 for removing contaminant 15 that may affect the "maximum altitude limit". When the discharge device 16 removes contaminant 15, the contaminant can be replaced with fluid used in the circulation. The discharge device 16 can separate the inside and outside of container 2, so that the closed container 2 forms a closed system.

[0071] Depending on the type of elements to be discharged from the enclosed container 2, the discharge device can be placed in other locations for different purposes. Preferred operations involve discharging unwanted elements from the fluid that could negatively affect circulation or lower maximum altitude limits. In the example shown, discharge device 16 is used for discharging air 15.

[0072] Figure 1C This is a detailed illustration of the cross-section of pipe 4, which comprises two pipes: a circulating input 7 and a circulating output 6. In the example shown, region 8 within the pipe is closed. Hydraulic pressure from the circulation device is evenly distributed across regions 6 and 7, which have opposite values. When valve 13 is open and valve 14 is closed, the pipe forms a static hydraulic circuit until it is subjected to... Figure 1A The effect of the force (pressure) generated by the central circulation device 11.

[0073] If an additional circulation device is introduced in the output pipe 10 (6), then region 8 in the surrounding pipe 4 can operate as a differential loop. If the flow rate in the input pipe 9 (7) is higher or lower than the flow rate in the output pipe 10 (6), the loop created by region 8 handles the difference. Any pipe configuration is possible as long as the start / stop mechanism can open and close the loop as intended. Figure 1C As shown, it might be better to group the pipelines together, since traditional start-stop mechanisms such as ball valves are used.

[0074] The position of the pipe within the closed container 2 depends on the preferred fluid used for circulation, removal of contaminants, etc. In the example shown, with water as the fluid, it would be ideal if the extraction pipe 5 were placed horizontally on the left side of the closed container 2. This would result in lower hydrostatic pressure when valve 13 is closed and valve 14 is open. Pipe 5 can be as short as possible to create a more efficient circulation.

[0075] The position of the closed container 2 can be submerged in the fluid in the raised container 3 (e.g., Figure 5 (As shown in 70 of the alternative implementation). This simplifies the removal of pollutants or air and is more optimized in terms of altitude and circulation. Furthermore, the source container can also be a closed container, such as... Figure 5 The alternative implementation shown is 69. This optimization can increase the maximum elevation height. However, these illustrations are exemplary, and the preferred locations of the pipes and containers may change if the fluid is not water or if more optimized circulation parameters are required.

[0076] Figure 2 , Figure 3 and Figure 4 This illustrates how cyclic units connected in parallel and in series are formed. Figure 2 and Figure 3 The basic loop units for parallel and series connections are shown. Figure 1 ). Figure 4 yes Figure 3 A variation of a cyclic unit connected in series.

[0077] Parallel-connected circulation units will increase flow, while series-connected circulation units will increase elevation in a resistance-free manner without reducing the efficiency of the circulation system.

[0078] Parallel and series-connected circulation units can also introduce additional functionality. They may contain fluids of different compositions and have different locations within the system.

[0079] Similarly, containers can represent additional functionality. Multiple containers can represent fluids with different compositions. In an exemplary embodiment, the source container and the raised container are shown as a single container. If they represent multiple containers and different circulation units are used in parallel, the functionality of the system can be greatly increased. As an example, if a contaminant is present at the bottom of a raised container, the contaminant can be moved to a separate source container using a circulation unit, such as... Figure 9 The alternative implementation is shown in the diagram. This demonstrates that multiple functions can be separated by containers and multiple loop units connected in parallel and series. By using an elevated buffer container 44 ( Figure 3 The functionality can be further enhanced by introducing multiple elevated (open or closed) buffer containers.

[0080] Valves 13 and 14 are start-stop mechanisms and can be of any form, as long as they are capable of shutting off the conveyor (pipeline) and closing the circulation loop. Since air or other contaminants in the fluid can affect hydrostatic pressure, their location should be as low as possible. If they increase the maximum altitude limit, other configurations and implementations of the number and location of valves can be envisioned. The valves can be combined into a single start-stop mechanism with one input in container 2 and two outputs in containers 1 and 3, so that one input operates one output simultaneously. Using two separate valves simplifies the illustration and description of the innovation.

[0081] Equally important, this system is a closed system. If one of valves 13 and 14 is open and the other is closed, the system is closed. If both valves 13 and 14 are open simultaneously, the system is open, and fluid will begin to flow downwards from the elevated container 3 to the source container 1. Electronic monitoring and control can be implemented to keep the hydraulic system in a static state. Start-stop mechanisms, circulation mechanisms, and discharge mechanisms can be controlled and monitored electronically. Furthermore, sensors can be implemented to monitor the flow in pipes (4 and 5) and contaminants in containers (1, 2, and 3) to monitor and control the sequence of circulation units without affecting the maximum altitude limit. The electronic control system must be able to monitor whether the system is a closed hydraulic system to allow for unrestricted circulation and prevent downward flow.

[0082] Although the above embodiments have been described in some detail for clarity of understanding, the present invention is not limited to the details provided. Many alternative methods can be used to implement the invention. The disclosed embodiments are illustrative and not restrictive.

[0083] Best way to carry out the invention Optimal operating mode for basic loop units: Figure 1 This illustrates the resistance-free circulation of fluid from source container 1 to the raised container 3.

[0084] Before operation, containers 2 and pipes 4 and 5 must be filled with liquid. This can be done via air venting device 16, or by vacuuming, or by a combination of pumping or circulating water filling and emptying. Before operation, all valves must be closed and the circulation device must be stopped.

[0085] Initially, valve 13 is open, and the hydrostatic pressure generated by the water in container 2 and the fluid in pipe 4 will prevent any flow from container 2 into source container 1. This gives us a static hydraulic system in which there is no flow from container 2 to source container 1. Pascal's law states that in a static, closed fluid, a pressure change at any point is transmitted undiminished to all points in the fluid.

[0086] For simplicity, Figure 1 The loop units shown can be grouped in a loop: • Supply unit 1, including valve 13, pipe 4 and circulation device 11 • Extractor 1, including circulation device 12, pipe 5 and valve 14 When the circulation device stops and the valve closes, the loop is closed; when the circulation device starts and the valve opens, the loop opens. The supply unit cannot circulate simultaneously with the extraction unit, thus forming a closed system with closed container 2.

[0087] The circulation from source container 1 to raised container 3 is accomplished by opening the supply unit and closing the extraction unit. After the optimal circulation, the supply unit will be closed and the extraction unit will be opened. After the optimal circulation, the fluid in raised container 3 has been replaced by the fluid in closed container 2.

[0088] If it is necessary to remove unwanted elements from container 2, both the supply and extractor are shut off until the removal is complete.

[0089] The flow in the loop between source container 1 and raised container 3 is discontinuous. The extractor and the supply cannot operate simultaneously.

[0090] The described mechanism provides a way to circulate fluid to an elevated height without resistance. Energy is used only for circulation and for resistance movement through the pipes.

[0091] Optimal operating mode based on multiple loop units connected in parallel: Figure 2 This illustrates how a variation of the invention combines several cyclic units in parallel (from...) Figure 1 To increase the circulation flow.

[0092] For simplicity, the system shown can be grouped according to cyclic loops: • Supply unit 1, including valve 18, pipe 19 and circulation device 20 • Extractor 1, including circulation device 23, pipe 24 and valve 25 • Supply device 2, including valve 26, pipe 27 and circulation device 28 • Extractor 2, including circulation device 31, pipe 32 and valve 33 The supply circuit cannot operate simultaneously with the extraction circuit. • System 1, comprising supplier 1 and extractor 2 • System 2, comprising supplier 2 and extractor 1 When the circulation device stops and the valve closes, the loop is closed; when the circulation device starts and the valve opens, the loop is open. The supply unit and the extraction unit cannot circulate simultaneously on the same circulation unit, thus enclosing containers 21 and 29 form a closed system.

[0093] To obtain a loop from source container 17 to the raised container 34, parallel operations will create a continuous flow if the components in system 1 are open while the components in system 2 are closed. The same applies when the components in system 1 are closed and the components in system 2 are open.

[0094] A cycle can represent the dilution of liquids of different purities, and parallel-connected cycle units will propagate this effect in parallel.

[0095] Adding multiple parallel units will continuously increase the flow in a smooth and uninterrupted manner. Parallel operation can decouple the function for each system if the location, contents, and purpose of each unit change.

[0096] Optimal operating mode based on multiple cascaded loop units: Figure 3 A variation of the invention is shown, which increases altitude by combining several cyclic units in series.

[0097] The hydrostatic pressure is based on the height between the source container and the raised container. A system of units connected in series will address any unwanted increases in hydrostatic pressure. Each unit connected in series will operate below the maximum raised height.

[0098] To simplify, the system can be divided into loops: • The supply unit 1 includes a valve 36, a pipe 37, and a circulation device 38.

[0099] • Extractor 1 includes circulation device 41, pipe 42 and valve 43.

[0100] • The supply unit 2 includes a valve 45, a pipe 46, and a circulation device 47.

[0101] • Extractor 2 includes circulation device 50, pipe 51 and valve 52.

[0102] When the circulation device stops and the valve closes, the loop is closed; when the circulation device starts and the valve opens, the loop opens. The supply unit and the extraction unit cannot circulate simultaneously on the same circulation unit, therefore, closed containers 39 and 48 form a closed system.

[0103] The loop unit is connected to the open buffer container 44 and can operate independently, similar to the basic loop unit. The flow in the series-connected system will be interrupted by the start / stop mechanism.

[0104] A circulation system can represent the dilution of liquids of varying purities. Circulation units connected in series will propagate this effect sequentially.

[0105] This design will eliminate the problem of high hydrostatic pressure at high altitudes. Each cascaded circulation unit will circulate in a resistance-free manner.

[0106] Optimal operating mode based on multiple cascaded loop units without opening the buffer container: Figure 4 A variation of the invention is shown, which increases altitude by combining several cyclic units in series.

[0107] The illustration shows a cycle in a container that depends on the previous container.

[0108] This variant does not require opening the raised container, but each unit depends on the valve in the subsequent container.

[0109] For the preceding unit to function properly, the subsequent valves must be closed.

[0110] To simplify, the system can be divided into loops: • Supply unit 1, including valve 55, pipe 56 and circulation device 57.

[0111] • The supply unit 2 includes a valve 60, a pipe 61, and a circulation device 62.

[0112] • Extractor 1 includes circulation device 65, pipe 66 and valve 67.

[0113] Supply 1 is replacing the fluid in container 58 with the fluid in source container 54. During this operation, supply 2 is shut off.

[0114] When supply 1 is closed, supply 2 is opened, and the fluid in container 63 circulates with the fluid in container 58. During this operation, extractor 1 is stopped.

[0115] The last operation is performed when supplier 2 stops; both supplier 1 and extractor 1 can cycle.

[0116] Extractor 1 circulates the contents of container 63 with the raised container 68.

[0117] A circulation can represent the dilution of fluids of different purities. A series of connected circulation units will propagate this effect sequentially.

[0118] This variant does not require an elevated, open buffer container and can be designed with multiple units in a series-connected tubing column to allow fluid circulation to extremely high elevations.

[0119] Optimal operating mode based on multiple cyclic units connected in series and parallel: The present invention is shown in different embodiments, wherein Figure 1 The basic unit shown is as Figure 2 , Figure 3 , Figure 4 Multiple units connected in series or in parallel are connected together.

[0120] Multiple cyclic units connected in parallel or in series via multiple containers are not shown in the figure, but can be constructed to further optimize functionality.

[0121] In mathematics, series and parallel connections introduce Boolean algebra, and multiple parallel and series connections can create functions that produce optimal, unhindered circulation to an elevated container in any way or form.

[0122] The complexity of operating parallel and series circulating units introduces some form of control system and electronically controlled start-stop sequence. The control system can monitor the system to ensure that the elevated container remains below its maximum elevation limit, preventing downward flow from the elevated container towards the source container.

[0123] The optimal operating mode for such a system is similar to that of series and parallel connected units, but the functionality is multiplied in a computer control system.

[0124] How to perform a resistance-free loop at an elevated altitude? As demonstrated in the exemplary embodiments, fluid can be efficiently circulated to an elevated position by utilizing the principle to establish a static hydraulic system and introducing resistance-free circulation.

[0125] The present invention relies on the sequential control of the start-stop mechanism and the circulation mechanism to form a closed system for resistance-free circulation.

[0126] How to generate a continuous increase in flow? Examples show that by connecting resistance-free circulating units in parallel, we can achieve an increase in resistance-free and uninterrupted flow.

[0127] This can solve the problem that energy consumption increases linearly with increasing volume relative to the fluid's volume.

[0128] Solving the problem of increasing altitude Studies have shown that connecting multiple cyclic units in series can increase altitude several times over with high efficiency.

[0129] This can solve the problem that energy consumption increases linearly with increasing altitude relative to the increase in height.

[0130] Alternative implementation methods Some variations can be envisioned.

[0131] Variant 1 Figure 5 The envisioned design involves immersing the recirculation unit within both the source and elevated containers. This creates a closed source and elevated container, increasing the elevation limit for the system. This is advantageous for small, inexpensive systems, as well as for very high-altitude systems where the number of cascaded buffer containers can be reduced to achieve high energy efficiency.

[0132] Variant 2 Another variation of the invention is Figure 6 The diagram shows the circulation units connected in series, but the elevated circulation container is not opened. This series-connected variant is a cost-effective way to circulate to higher altitudes.

[0133] Variant 3 Figure 6 It is also envisioned that start-stop mechanisms, circulation mechanisms, and conveyors be combined to form a transfer function for circulation between two containers. These could be multiple stacked units, thus forming a pipeline of containers that facilitates transfer between them. This is Figure 4 A variation of the cascaded loop unit shown.

[0134] Variant 4 exist Figure 7 The invention also envisions its use for transferring fish between a source container and an elevated container. Figure 7Slightly different from the previous illustration, this design introduces two valves 76 and 78 on the extraction circulation loop and two valves 80 and 82 on the source circulation loop. Therefore, when operating the source loop, both extraction valves must be closed, while the source valves are open. Similarly, when operating the extraction loop, both source valves must be closed when the extraction valves are open. Another difference is that pipes 75 and 83 extend into the enclosed container, providing better displacement of the fluid within the tank when source or extraction circulation occurs. Circulation devices 74 and 84 are standard recirculation pumps. The enclosed container stands between the source and extraction containers, creating a vacuum when source valves 80 and 82 are open. This can negatively impact marine life. The directional arrows in circulation devices 74 and 84 indicate the direction of the source and extraction flow, indicating that fish typically swim against the current, thus defining the transport direction. The direction can be reversed, or additional units can be installed in parallel to allow for transfer of fish (marine life) in another direction.

[0135] Fish production, particularly salmon production, is plagued by salmon lice. The normal response of infected salmon is to seek freshwater. One of the containers can be a freshwater container, which can also be used for feeding, thus periodically exposing the fish to freshwater in which salmon lice cannot survive. A variation of the invention can also prevent salmon lice by collecting water at a depth below their habitat using one of the source pipes 81, 83.

[0136] Variant 5 Figure 8 It is also envisioned that the invention can be used alone in the source container to avoid a vacuum that may be unsuitable for marine life. This would also effectively increase the elevation. In this variant, the distance between the source circulation loops 86, 88 is increased so that the fluid circulation from the potentially contaminated elevated container does not mix with the source fluid. The distance can be further increased to enhance the effect. Similarly, the distance between the extraction circulation loops 96, 99 will improve the displacement of the fluid in the tank used for the circulation unit.

[0137] like Figure 8A The aerator shown depicts an air inlet conduit 101 that distributes air from an air pump 94 in an annular fitting with an air inlet to a circulation conveyor 102. It is well known that aerators can reduce the density of water and provide a positive lift. If a fluid with a density Y87 is higher than a fluid with a density X100 in a raised container, the aerator can compensate for any pressure difference that may arise between fluids of different densities and weights.

[0138] A mesh filter 97 is inserted into an elevated container to illustrate the separation of fluid from contaminants containing particles, such as marine excrement or other types of contaminants with a certain particle size. In the figures, a particle size of 5 micrometers is used. In this exemplary embodiment, it is assumed that the filter has a flow rate higher than that provided by the circulation device. The effect of such a filter may not affect the circulation device and resistance-free circulation.

[0139] This variant can replace the transportation of marine organisms (fish), such as Figure 7 The envisioned device might be more suitable due to the absence of a vacuum. Marine life is adapted to pressure and depth, but less so to pressures below atmospheric pressure.

[0140] Variant 6 Figure 9 The plan also envisions how to utilize the increased weight provided by the high-density fluid to remove contaminated, high-density fluid from an elevated container. Circulation devices 105 and 114 may not be necessary for providing circulation, as the high-density fluid provides additional weight and will move downwards, and positive circulation can be provided without circulation devices 105 and 114. Due to this effect, circulation devices 105 and 114 can be included to accelerate the process of transporting contaminated (high-density) fluid from the elevated container with increased efficiency. Marine life (fish) can be a source of contamination, and the device can be used in conjunction with... Figure 8 The provided ideas are used in combination with other variations.

[0141] Variant 7 Figure 10 It was also envisioned how to use the siphon principle instead of a pump to circulate fluid into an elevated container. Source circulation conveyors 127, 128 and source circulation start-stop mechanisms 126, 129 circulate fluid from an elevated container 130 to a container 125 using the siphon principle.

[0142] Height 131 allows fluid to flow in supply conveyors 128 and 127, and height 124 allows fluid to flow in extraction conveyors 121 and 118.

[0143] The closed container 119 will contain fluid from container 130. When the start / stop mechanisms 126 and 129 in the source circulation are closed and the start / stop mechanisms 117 and 122 are open, the extraction circulation displaces fluid from the source container 130 and moves it to the raised container 116, thereby circulating water to the raised container solely based on the siphon principle. During this process, depending on how the fluid displacement is controlled, the fluid in the raised container can be a mixture of fluids from the source container 129 and the raised container 122.

[0144] Variant 8 Figure 11The plan also envisions how to use a resistance-free circulation device to transport fluid net forward to an elevated container. Since any circulation involves a pressure increase, the elevated container could utilize air or compressible gas as a damping element within enclosed elevators 138 and 146. The elevated, enclosed container includes a top component that functions as a piston 137, wherein the piston sealing ring... Figure 11B As shown in 145. Figure 11C A closed annular container 147 with trapped gas 146 and a spring damper support 148 are shown.

[0145] Combination Figure 11A The spring damper 144 shown, when fluid circulates into the closed container, the increased pressure from the circulation device 133 will reduce the vacuum and thus increase the volume of the closed container. If the start-stop mechanisms in sources 132, 134 close rapidly in sequence, the damping elements (gas and spring damper) will not respond quickly enough and release excess water through source circulation conveyors 135, 136. When the start-stop mechanisms 141, 143 in the extractor are opened, this pressure is released, and some fluid is delivered to the raised container through the extractor circulation conveyors 139, 140.

[0146] The volume of the closed container, the sequence and speed of operation of the start-stop mechanism, and the pressure from the circulation device will determine the volume of fluid transferred between the source container and the raised container.

[0147] In the above variation, the piston is the power source, thereby displacing the circulation device. If the piston operates within the entire closed container, it can also function as a displacement mechanism.

[0148] The technical advantage of using a piston as a separator is that it completely avoids mixing fresh water and wastewater. In this way, the water in the raised container can be more effectively replaced by fresh water. Variation 9 below also envisions this water separation.

[0149] Variant 9 Figure 12 The paper also envisions how a closed container would improve the efficiency of fluid displacement between the source and extractor. Since the closed container undergoes a switching process between the source and extractor, this would affect how the fluid from the raised container is diluted (mixed) within the closed container.

[0150] If the elevated container is used as a marine habitat, the oxygen in the water will be depleted over time. This invention replaces the oxygen-depleted water in the elevated container with fresh, oxygen-rich water from this source. The effectiveness of the innovation is diminished if the water is mixed in a closed container and multiple recirculations of the closed container are required.

[0151] This is addressed by the displacement barrier 159, which slides on the guide roller support 160 of the central rod attached to the tank.

[0152] The source circuit includes valves 149 and 158 and conveyors 152 and 155. The extraction circuit includes valves 150 and 157 and conveyors 151 and 156.

[0153] As can be seen, when the source fluid 154 is circulated into the closed container, the displacement barrier moves to the left and displaces the raised container fluid 153 into the source container through the source loop. Similarly, when the raised container fluid 153 is circulated into the closed container, the displacement barrier moves to the right and displaces the source fluid into the raised container through the extraction loop.

[0154] When displacing the volume within the sealed container in a single operation, the displacement barrier ensures near 100% displacement. This is less efficient than the piston operation envisioned in Variant 8, but can be more cost-effective when the sealed container is quite large.

[0155] Other variations It is also conceivable that parallel and series-connected units can form multiple circulation units with multiple containers. These multiple circulation units will combine to create optimal circulation, allowing for the calculation of impurities (concentrations) in the fluid within different containers based on the specified function of the overall circulation system. In a construction with multiple circulation units, it is also conceivable that some circulation units can circulate fluids with different compositions and for purposes different from the other circulation units.

[0156] Energy savings can also be achieved between containers if required by the application by using heat exchangers between the conveyors.

[0157] Other variations of the invention may include different types of filters for removing contaminants or other harmful elements from a stream.

[0158] Different types of valves will produce beneficial effects. It is conceivable that the four valves on each side of the closed container could be replaced by two rotating discs with gaskets and orifices therein, and a central axis passing through the closed container. This would act as gate valves for the input and output on both sides of the closed container. The orifices in the discs open the source loops at both ends and close the extraction loops at both ends as they rotate. The discs can rotate at closing and opening rates according to the flow and displacement within the closed container. In a parallel configuration, the valves can act as flap valves, such that when the input loop of one circulation unit is closed, the other input loop is open. The number of valves can be reduced if the input and output sections can be combined with valves that switch between the conveyor and the circulation loop. Many conventional valves can be used, or custom hinged valves with a switching configuration can be used, where at least one input can switch between multiple circulation loops.

[0159] Industrial applicability The invention, as claimed, discovers a method for frictionless circulation in a container at an elevated height using a particularly energy-efficient circulation unit.

[0160] Land-based fish farming and elevated greenhouses are key applications requiring energy-saving recycling at elevated heights.

[0161] This invention will have many other industrial applications for displacing fluids in tanks at elevated heights, where the fluids become contaminated or diluted over time, and can be displaced through circulation.

[0162] This invention has a wide range of applications because it is extremely efficient in circulating water to an elevated container.
