Description

Technical Field

[0001] This application relates to the field of water replenishment equipment technology, and in particular to a low-energy automatic water replenishment system. Background Technology

[0002] In industrial production and daily life, many scenarios involve the use of water-using equipment, especially equipment requiring heat exchange or refrigeration. Water-using equipment needs timely water replenishment during long-term operation to ensure its normal functioning. Failure to replenish water in a timely and effective manner may lead to decreased equipment performance or even malfunctions, affecting the stability and reliability of the entire system. Existing water replenishment systems often use water pumps to draw water from a replenishment tank and supply it to the heat exchanger or refrigeration equipment. However, the pump blades are constantly immersed in water, making the pump extremely prone to rust. If subsequent water replenishment is needed, the pump is easily jammed due to rust, resulting in unstable operation, inability to replenish water in a timely manner, and a high failure rate. Utility Model Content

[0003] This application provides a low-energy automatic water replenishment system to solve the problem that current water replenishment equipment uses water pumps that are prone to rust, leading to unstable operation or even difficulty in timely water replenishment.

[0004] A low-energy automatic water replenishment system includes:

[0005] Water-using equipment, containing water inside;

[0006] A water supply tank, which is hollow inside and contains water, is connected to the water-using equipment and can supply water to the water-using equipment.

[0007] A pneumatic component is connected to the water supply tank and is capable of releasing gas to pressurize the water in the water supply tank, allowing the water in the water supply tank to enter the water-using equipment.

[0008] By adopting the above technical solution, water replenishment is replaced with pneumatic components, eliminating the need for electric drive and significantly reducing energy consumption. This avoids pump malfunctions caused by long-term use, resulting in more stable system operation and extended service life. When the water level in the water-using equipment decreases, causing a drop in gas pressure, the pneumatic components automatically pressurize the water in the replenishment tank, ensuring timely water replenishment and guaranteeing the continuous and stable operation of the water-using equipment.

[0009] In one embodiment, the pneumatic component includes a liquid gas tank and a pressure reducing valve. The liquid gas tank is connected to the water supply tank and can fill the water supply tank with gas. The pressure reducing valve is located between the liquid gas tank and the water supply tank and can reduce the pressure of the gas released from the liquid gas tank. The gas pressure in the water supply tank is equal to the gas pressure in the water-using equipment.

[0010] By adopting the above technical solution, the liquid gas tank and the pressure reducing valve work together to reduce the pressure of the high-pressure gas to a suitable range, so that the pressure in the water replenishment tank is balanced with the pressure in the water-using equipment, ensuring that no water is replenished under normal conditions, and water replenishment is only started when the pressure of the water-using equipment drops, thus precisely controlling the timing of water replenishment.

[0011] In one embodiment, the low-energy automatic water replenishment system further includes a water replenishment tank, the water replenishment tank is provided with a water inlet and a water replenishment valve, the water replenishment tank is connected to the water inlet, and the water replenishment valve can control the opening and closing of the water inlet.

[0012] By adopting the above technical solution, the water replenishment tank, water inlet and water replenishment valve are set up to provide a water source replenishment channel for the water replenishment tank. When the water level in the water replenishment tank is insufficient, water can be manually replenished from the water replenishment tank by opening the water replenishment valve to ensure that the water replenishment tank has water continuously and maintain the water replenishment function of the system.

[0013] In one embodiment, the low-energy automatic water replenishment system further includes a level sensor and an alarm. The level sensor is located inside the water replenishment tank and can monitor the water level. The alarm is electrically connected to the level sensor.

[0014] By adopting the above technical solution, the liquid level sensor monitors the water level in the water replenishment tank in real time. When the water level is lower than the minimum water level or higher than the maximum water level, the alarm will be issued in time to remind the staff to take measures to avoid the water replenishment tank from affecting the system operation.

[0015] In one embodiment, the low-energy automatic water replenishment system further includes a controller electrically connected to the level sensor, alarm, and water replenishment valve.

[0016] By adopting the above technical solution, the controller is connected to these devices to achieve automated control. When the level sensor detects that the water level has reached the minimum level, it automatically sends a signal to the controller, which then controls the water supply valve to open, thereby improving the water supply efficiency and the degree of system automation; when the water level reaches the maximum level, the controller controls the water supply valve to close.

[0017] In one embodiment, the water tank is further provided with a pressure relief valve, which is electrically connected to the controller, and a one-way valve is provided between the water tank and the water-using equipment.

[0018] By adopting the above technical solution, the pressure relief valve can restore the pressure in the water supply tank to atmospheric pressure, eliminate the obstruction caused by excessive pressure in the tank during water supply, and allow water from the water supply pool to smoothly enter the water supply tank, ensuring the smooth progress of the water supply process; at the same time, the one-way valve ensures that water can only flow from the water supply tank to the water-using equipment and cannot return.

[0019] In one embodiment, the pneumatic component further includes a shut-off valve located between the liquid gas tank and the water replenishment tank. The shut-off valve is electrically connected to the controller and is capable of controlling the flow of gas within the liquid gas tank.

[0020] By adopting the above technical solution, the controller is electrically connected to the shut-off valve. When the water level drops to a certain level, the controller controls the shut-off valve to close, preventing the liquid gas tank from continuing to fill the water tank with gas. This then controls the pressure relief valve to open, and after a period of time, the water supply valve is opened to facilitate water replenishment to the water tank, thus achieving intelligent linkage of multiple components.

[0021] In one embodiment, the water tank is further provided with an isolation element that can isolate the gas and water inside the water tank.

[0022] By adopting the above technical solution, the isolation component separates the gas and water in the water supply tank, preventing the gas from dissolving in the water and causing pressure changes, ensuring that the pressure of the water supply tank and the water-using equipment always remains balanced, and ensuring the normal operation of the water supply system; furthermore, it can use different high-pressure gases to pressurize the water, expanding the scope of application.

[0023] In one embodiment, the isolation element is an airbag, which is connected to the liquid gas tank and the pressure relief valve.

[0024] By adopting the above technical solution and connecting it with the liquid gas tank and pressure relief valve, it can flexibly expand and contract according to changes in gas pressure, effectively isolating gas and water, adapting to system pressure fluctuations, and ensuring the stable operation of the water replenishment system.

[0025] In one embodiment, the isolation element is an isolation plate that abuts and seals against the inner wall of the water tank, with the lower surface of the isolation plate in contact with water and the upper surface in contact with gas.

[0026] By adopting the above technical solution, the gas pressure is ensured to be stably transmitted to the water surface through the isolation plate, so as to achieve reliable water replenishment; at the same time, the structure is simple and easy to install and maintain.

[0027] In summary, this application includes at least one beneficial effect:

[0028] 1. By switching to pneumatic water replenishment, no electricity is required, significantly reducing energy consumption; this avoids pump malfunctions caused by long-term use, resulting in more stable system operation and extended service life. When the water level in the water-using equipment decreases, causing a drop in gas pressure, the pneumatic component automatically pressurizes the water in the replenishment tank to replenish water promptly, ensuring the continuous and stable operation of the water-using equipment.

[0029] 2. The controller is electrically connected to the shut-off valve. When the water level drops to a certain level, the controller controls the shut-off valve to close, preventing the liquid gas tank from continuing to fill the water tank with gas. This, in turn, controls the pressure relief valve to open. After a period of time, the water supply valve is opened to facilitate water replenishment to the water tank, thus achieving intelligent linkage of multiple components.

[0030] 3. The isolation component separates the gas and water in the water supply tank, preventing the gas from dissolving in the water and causing pressure changes. This ensures that the pressure between the water supply tank and the water-using equipment remains balanced, guaranteeing the normal operation of the water supply system. Furthermore, it allows the use of different high-pressure gases to pressurize the water, expanding the range of applications. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-3 The low-energy automatic water replenishment system provided in this application will be described in further detail.

[0036] Example 1

[0037] Please see Figure 1-3 The low-energy automatic water replenishment system provided in this application includes a water-using device 1, a water replenishment tank 2, and a pneumatic component 3.

[0038] like Figure 1As shown, the water-using device 1 contains water and is used for cooling and heat exchange. The outer surface of the water-using device 1 is typically made of metal, such as stainless steel, which has good thermal conductivity and corrosion resistance. It can be various devices requiring heat exchange operations, suitable for heat exchangers in heating systems or condensers and air conditioners in refrigeration systems, and also applicable to industrial cooling towers that cool objects by spraying water. In this embodiment, the water-using device is a heat exchanger in industrial production; it is cylindrical in shape, made of metal, and has good thermal conductivity. In other embodiments, the water-using device can be a radiator in a residential heating system; it has a sheet-like structure and also utilizes the circulating flow of water to transfer heat. During normal operation, the water in the internal water tank participates in the heat exchange process, ensuring the normal operation of the system.

[0039] The water tank 2 is hollow and contains water. It is typically made of sturdy plastic or metal, such as polyethylene or carbon steel. Its shape can be cylindrical or square to accommodate different installation spaces. The water tank 2 is equipped with a water supply pipe connected to the water-using equipment 1. This pipe is usually made of PVC or steel, and its outlet extends into the water in the water-using equipment 1.

[0040] The pneumatic component 3 is connected to the water supply tank 2 and can release gas to pressurize the water in the water supply tank 2, causing the water in the water supply tank 2 to enter the water-using device 1. This achieves the effect of timely water replenishment when the water in the water-using device 1 decreases. The reason for this is that the pressure applied by the pneumatic component 3 drives the water in the water supply tank 2 to flow, which does not require electric drive like a water pump. This results in more stable operation, reduced energy consumption, reduced probability of failure, and extended system life.

[0041] Specifically, the pressure component 3 includes a liquid gas tank 31 and a pressure reducing valve 32. The liquid gas tank 31 is typically made of high-strength alloy steel, capable of withstanding high pressure, and stores a water-insoluble liquid gas, such as nitrogen. The liquid gas tank 31 is connected to the water supply tank 2 via an inlet pipe, which must also possess good pressure resistance and sealing performance. The pressure reducing valve 32 is located in the inlet pipe; it reduces the high-pressure gas released from the liquid gas tank 31 to a suitable pressure before pressurizing the water in the water supply tank 2. Simultaneously, the gas pressure in the water-using device 1 is the same as the gas pressure in the water supply tank 2, so under normal circumstances, the water supply tank 2 will not replenish water to the water-using device 1. When the water in the water tank of the water-using device 1 decreases, its internal gas pressure decreases, while the water supply tank 2 maintains a stable pressure. At this time, the water in the water supply tank 2 will enter the water-using device 1 under the pressure of the gas until the pressures of the two are equal. In this embodiment, the gas pressure in the liquid gas tank 31 is 2 MPa. After being reduced to 3 to 4 MPa by the pressure reducing valve 32, it pressurizes the water in the water supply tank 2. Both the water supply tank 2 and the water storage tank of the water-using equipment 1 can be equipped with pressure sensors to facilitate monitoring of the internal gas pressure. The pressure reducing valve 32 is generally a pilot-operated pressure reducing valve 32 or a direct-acting pressure reducing valve 32. The pilot-operated pressure reducing valve 32 has high adjustment accuracy and is suitable for occasions with strict pressure requirements; the direct-acting pressure reducing valve 32 has a simple structure and rapid response, and is commonly used in general pressure reduction scenarios.

[0042] The low-energy automatic water replenishment system also includes a water replenishment tank 4 and a water replenishment tank 2 equipped with a water inlet and a water replenishment valve 21. The water replenishment tank 4 is connected to the water inlet via the water replenishment valve 21, which controls whether water is replenished. The water replenishment tank 4 can be a concrete structure or a stainless steel tank, and its capacity is determined according to actual needs. The water replenishment valve 21 can be a ball valve or a gate valve, used to control the flow of water between the water replenishment tank 4 and the water replenishment tank 2. When there is no water in the water replenishment tank 2, the water replenishment valve 21 can be manually opened, allowing water from the water replenishment tank 4 to flow into the water replenishment tank 2.

[0043] The low-energy automatic water replenishment system also includes a level sensor 22 and an alarm 23. The level sensor 22 is located inside the water replenishment tank 2 and can monitor the water level. The alarm 23 is electrically connected to the level sensor 22. The level sensor 22 can be a float-type level sensor. The float-type level sensor 22 triggers a switch by the rise and fall of the float as the water level rises and falls. It has a simple structure and low cost. The alarm 23 can be an audible and visual alarm 23. When it receives a signal, it will emit a sound and flash a light to alert the staff. By monitoring the water level through the level sensor 22, the alarm 23 will sound when the water level in the water replenishment tank 2 is lower than the minimum water level, which will remind the staff to open the water replenishment valve 21 to replenish the water in the water replenishment pool 4. At the same time, when the water level is higher than the maximum water level, the alarm 23 will also sound, which will allow the staff to close the water replenishment valve 21 and reduce energy consumption.

[0044] The low-energy automatic water replenishment system also includes a controller, which is electrically connected to the level sensor 22, the alarm 23, and the water replenishment valve 21. The controller can be a programmable logic controller (PLC), which receives signals from the level sensor 22 and controls the opening and closing of the alarm 23 and the water replenishment valve 21 according to a preset program. When the water level in the replenishment tank 2 drops, the level sensor 22 sends a signal to the controller. The controller analyzes whether the actual water level is within the limit range and then controls the alarm 23 to sound an alarm. Simultaneously, it can directly control the opening and closing of the water replenishment valve 21 or manually control its opening and closing.

[0045] The water supply tank 2 is also equipped with a pressure relief valve 24. The pressure relief valve 24 is generally installed on the top of the water supply tank 2 and electrically connected to the controller; it can be a spring-loaded pressure relief valve 24. When water needs to be added to the water supply tank 2, the controller first restores the pressure inside the water supply tank 2 to atmospheric pressure through the pressure relief valve 24 before starting water replenishment, preventing the pressure inside the water supply tank 2 from increasing and making water replenishment difficult. Therefore, the pressure sensor is also electrically connected to the controller, facilitating timely closure of the pressure relief valve 24 based on pressure changes, avoiding wasted time. A one-way valve 25 is installed on the water supply pipe between the water supply tank 2 and the water-using equipment 1, providing good sealing and durability, ensuring that water can only flow from the water supply tank 2 to the water-using equipment 1.

[0046] To avoid wasting gas in the liquid gas tank 31, the pneumatic components also include a shut-off valve 33. The shut-off valve 33 is located between the liquid gas tank 31 and the water supply tank 2. The shut-off valve 33 is electrically connected to the controller and can control the flow of gas within the liquid gas tank 31. The shut-off valve 33 can be an electric shut-off valve or a pneumatic shut-off valve. Electric shut-off valves are convenient to control and easy to automate; pneumatic shut-off valves have a fast response speed and are suitable for applications requiring high control speed. When the water level drops to a certain distance, the controller activates the alarm 23 and closes the shut-off valve 33. Then, it opens the pressure relief valve 24 to release pressure from the water supply tank 2. After this, the controller closes the pressure relief valve 24 and opens the water supply valve 21. When the water level is higher than the maximum water level, the controller again activates the alarm and closes the water supply valve 21, then opens the shut-off valve 33 to facilitate gas filling of the tank. Additionally, when the pressure sensor detects that the pressure in the water tank 2 has not reached the preset pressure after a certain period of replenishment, i.e., the liquid gas tank 31 has no pressure, the controller can control the shut-off valve 33 to close, thereby replacing the liquid gas tank 31.

[0047] The implementation principle of this embodiment is as follows: This low-energy automatic water replenishment system uses a pneumatic component 3 to replace a water pump to achieve the water replenishment function, avoiding the problems of high energy consumption and easy failure of water pumps. The setting of the controller, liquid level sensor 22, alarm 23, shut-off valve 33 and pressure relief valve 24 enables the system to automatically monitor the water level, promptly alarm and perform water replenishment operation when needed, improving the timeliness and accuracy of water replenishment.

[0048] Example 2

[0049] like Figures 2 to 3 As shown, this embodiment differs from the previous embodiment in that: the water replenishment tank 2 is also equipped with an isolation component, which can isolate the gas and water inside the water replenishment tank 2. Specifically, the isolation component can be an air bladder 26 or an isolation plate 27. If the isolation component is an air bladder 26, the air bladder 26 is connected to the liquid gas tank 31 and the pressure relief valve 24. The air bladder 26 is usually made of elastic materials such as rubber, and it can expand and contract with the filling and expulsion of gas. At this time, there is a gas insoluble in water outside the air bladder 26 inside the water replenishment tank. When the liquid gas tank 31 inflates the water replenishment tank 2, the air bladder 26 expands downward and abuts against the upper surface of the water. The gas outside the air bladder 26 is located above and isolated from the water, preventing the gas inside the air bladder 26 from dissolving in the water and causing the pressure to be different from that in the water-using equipment 1, making it difficult to replenish water to the equipment. If the isolation component is an isolation plate 27, the isolation plate 27 abuts and seals against the inner wall surface of the water replenishment tank 2. The lower surface of the isolation plate 27 is in contact with the water and the upper surface is in contact with the gas. The isolation plate 27 is generally made of plastic or metal, possessing good rigidity and sealing properties. It can slide within the water tank 2, moving up and down with changes in water level to maintain a constant separation between gas and water. Additionally, a sealing ring can be provided on the outer surface of the isolation plate 27, abutting against the inner wall of the water tank 2 for sealing, and the sealing ring can also move with the isolation plate 27. The lowest point of the isolation plate 27 is higher than the water inlet and the level sensor 22, preventing water from the water inlet from falling onto the upper surface of the isolation plate 27.

[0050] The implementation principle of this embodiment is as follows: the use of the isolation component ensures the stability of the gas pressure inside the water replenishment tank 2, further improving the stability and reliability of the system. Compared with the prior art, it greatly reduces the operating cost and maintenance workload, and extends the service life of the system. At the same time, the use of water-soluble gas to pressurize the water replenishment tank 2 improves the applicability of the system.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
