[0002] In the field of metallurgical hydrometallurgy, there are many processes that require water replenishment in a short period of time.

[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] like Figure 1 As shown, the liquid supply system in this embodiment includes a liquid storage tank 1, an infusion component 2 and a pressurized energy storage component 3, the liquid storage tank 1 is used to store liquid; the liquid inlet of the infusion component 2 is connected to the liquid outlet of the liquid storage tank 1; the pressurized energy storage component 3 includes an energy storage tank 31 and a high-pressure gas supply component 32, the liquid inlet of the energy storage tank 31 is connected to the liquid outlet of the infusion component 2, the gas outlet of the high-pressure gas supply component 32 is connected to the gas inlet of the energy storage tank 31, and the gas inlet of the energy storage tank 31 is located above the liquid level in the energy storage tank 31, the high-pressure gas supply component 32 is used to transport gas into the energy storage tank 31 to discharge the liquid in the energy storage tank 31 by air pressure, and the liquid outlet of the energy storage tank 31 is connected to the liquid replenishment terminal 15.

[0019] Specifically, the liquid in the liquid storage tank 1 is stored according to the liquid required by the liquid infusion terminal 15. For example, if the liquid required by the liquid infusion terminal 15 is water, a certain amount of water can be pre-stored in the liquid storage tank 1. Of course, when the liquid infusion terminal 15 needs other liquids, other liquids can also be injected into the liquid storage tank 1, which is not limited here. Figure 1 As shown, the liquid storage tank 1 is provided with a first liquid discharge pipe, and the first liquid discharge pipe is provided with an eleventh valve 4 to control the opening and closing of the first liquid discharge pipe through the eleventh valve 4. When the liquid storage tank 1 needs to store liquid, the eleventh valve 4 is closed, and when the system stops working and the liquid in the liquid storage tank 1 needs to be discharged, the liquid in the liquid storage tank 1 can be discharged through the eleventh valve 4. For example, the eleventh valve 4 can be a manual valve, and the opening and closing of the eleventh valve 4 can be manually controlled.

[0020] like Figure 1As shown, the liquid reservoir 1 is also provided with a second liquid level gauge 5, and the liquid level information in the liquid reservoir 1 can be obtained by the second liquid level gauge 5, so as to control the infusion component 2 to continue to transport liquid into the energy storage tank 31 according to the liquid level information in the liquid reservoir 1 obtained by the second liquid level gauge 5. Specifically, when the liquid level in the liquid reservoir 1 is lower than the preset liquid level, the infusion component 2 is controlled to stop infusion to reduce the damage to the system caused by dry operation.

[0021] When the liquid supply system in this embodiment is working, a certain amount of gas is transported into the energy storage tank 31 through the high-pressure gas supply component 32, and the liquid in the liquid storage tank 1 is transported into the energy storage tank 31 through the infusion component 2. When the liquid is transported into the energy storage tank 31, the gas in the energy storage tank 31 is compressed to increase the gas pressure in the energy storage tank 31, so that the liquid in the energy storage tank 31 can be discharged from the liquid outlet of the energy storage tank 31 under the action of the gas pressure, and then the liquid can be replenished through the energy storage tank 31 to the liquid replenishment terminal 15. By using compressed air as power, continuous and timely water supply to the liquid replenishment terminal 15 can be achieved, and the infusion component 2 does not need to have an instantaneous large flow rate transportation capacity, which is beneficial to reducing energy consumption.

[0022] In this embodiment, if Figure 1 As shown, the liquid supply system further includes a twelfth valve 6, the inlet of the twelfth valve 6 is connected to the liquid outlet of the liquid reservoir 1, and the liquid outlet of the twelfth valve 6 is connected to the liquid inlet of the infusion assembly 2. The twelfth valve 6 is a manual valve, so as to reliably cut off the liquid reservoir 1 and the subsequent infusion assembly 2 in an emergency.

[0023] In this embodiment, if Figure 1 As shown, the infusion assembly 2 includes a first delivery pump 21 , an inlet of the first delivery pump 21 is connected to the liquid storage tank 1 , and an outlet of the first delivery pump 21 is connected to the pressurized energy storage assembly 3 .

[0024] For example, the first delivery pump 21 can be a variable frequency pump, which can accurately control flow and pressure, is more energy-efficient and efficient, and gradually accelerates from low frequency and low speed to the required speed during startup, reducing the impact of starting current on the power grid and wear on mechanical components, thereby extending the service life of the equipment.

[0025] In this embodiment, the first delivery pump 21 delivers liquid into the energy storage tank 31. The specific model of the first delivery pump 21 can be selected as needed, and the lift of the first delivery pump 21 can ensure that the liquid can enter the energy storage tank 31, which is not limited here.

[0026] In this embodiment, if Figure 1As shown, the infusion component 2 also includes a first valve 22 and a second valve 23 and a second delivery pump 24 arranged in sequence along the delivery path. The liquid inlet of the first valve 22 is connected to the liquid outlet of the liquid storage tank 1; the liquid inlet of the second valve 23 is connected to the liquid inlet of the first valve 22, and the liquid outlet of the second delivery pump 24 is connected to the liquid outlet of the first delivery pump 21.

[0027] The model of the second delivery pump 24 can be the same as that of the first delivery pump 21 , and those skilled in the art can select the model according to the actual needs, which is not limited here.

[0028] The infusion assembly 2 in this embodiment includes two sets of parallel delivery pumps, namely the first delivery pump 21 and the second delivery pump 24. When the first valve 22 and the second valve 23 are both in the open state, the first delivery pump 21 and the second delivery pump 24 can operate simultaneously to jointly provide a higher total flow rate to the system. When one of the first valve 22 and the second valve 23 is open and the other is closed, one of the first delivery pump 21 and the second delivery pump 24 operates independently and the other is closed, which can provide a certain flow rate. When one fails, the other can work normally, thereby improving the stability and work efficiency of the system. The working mode of the infusion assembly 2 can be selected as needed and is not limited here.

[0029] In this embodiment, if Figure 1 As shown, the infusion component 2 also includes a third valve 25 , the liquid inlet of the third valve 25 is connected to the liquid outlet of the first delivery pump 21 , and the liquid outlet of the third valve 25 is connected to the liquid inlet of the pressurized energy storage component 3 .

[0030] For example, the third valve 25 may be a manual valve.

[0031] By setting the third valve 25 to control the on-off of the pipeline, it is possible to control whether the liquid delivered by the first delivery pump 21 enters the pressurized energy storage component 3, and when encountering an abnormal situation or when the downstream needs to be controlled, the third valve 25 can be used to quickly isolate the first delivery pump 21 and the pressurized energy storage component 3, which is beneficial to improving the safety and reliability of the system.

[0032] like Figure 1 As shown, the infusion component 2 also includes a fourth valve 26 , the liquid inlet of the fourth valve 26 is connected to the liquid outlet of the second delivery pump 24 , and the liquid outlet of the fourth valve 26 is connected to the liquid inlet of the pressurized energy storage component 3 .

[0033] The fourth valve 26 can control whether the liquid delivered by the second delivery pump 24 enters the subsequent pressurized energy storage assembly 3. The function of the fourth valve 26 is the same as that of the third valve 25, which will not be described in detail here.

[0034] In this embodiment, if Figure 1As shown, the liquid supply system further includes a first pressure gauge 7 , which is disposed on a pipeline between the liquid outlet of the infusion component 2 and the pressurized energy storage component 3 .

[0035] It can be understood that by setting the first pressure gauge 7 to obtain the pressure on the pipeline between the liquid outlet of the infusion component 2 and the pressurized energy storage component 3, it can be judged whether the infusion component 2 is working normally based on the pressure information monitored by the first pressure gauge 7 so that timely adjustments can be made.

[0036] In this embodiment, if Figure 1 As shown, the high-pressure gas supply component 32 includes a gas supply part 321, a fifth valve 322, and a sixth valve 323 which are sequentially connected along the conveying path. The fifth valve 322 is a check valve, and the sixth valve 323 is a flow regulating valve. The outlet of the sixth valve 323 is connected to the air inlet of the energy storage tank 31.

[0037] For example, the gas supply member 321 may be a compressor, and the compressor is provided to provide high-pressure gas to the energy storage tank 31. Of course, the gas supply member 321 may also be in other forms, which are not limited here.

[0038] It can be understood that by providing the gas supply part 321 to provide high-pressure gas to the energy storage tank 31, the fifth valve 322 can prevent the gas entering the energy storage tank 31 from flowing back, effectively ensuring the amount of gas in the energy storage tank 31, and the sixth valve 323 is a flow regulating valve, which can adjust the amount of gas entering the energy storage tank 31 according to demand.

[0039] In this embodiment, if Figure 1 As shown, the liquid supply system further includes a second pressure gauge 8, which is disposed in the energy storage tank 31, and is used to obtain pressure information in the energy storage tank 31 to adjust the opening of the sixth valve 323 according to the pressure information.

[0040] It can be understood that by arranging the second pressure gauge 8 on the energy storage tank 31 to timely obtain the pressure information in the energy storage tank 31, the opening of the sixth regulating valve is timely adjusted according to the obtained pressure information, so that when the pressure in the energy storage tank 31 is lower than the set value, gas is replenished in the energy storage tank 31 in time, thereby accurately controlling the pressure in the energy storage tank 31, so that the energy storage tank 31 can stably and continuously supply water to the liquid replenishment terminal 15.

[0041] In this embodiment, the liquid supply system further includes a controller (not shown in the figure), and the second pressure gauge 8 and the sixth valve 323 are both electrically connected to the controller, and the controller can adjust the opening of the sixth valve 323 according to the pressure information in the energy storage tank 31 obtained by the second pressure gauge 8. The connection method and working principle of the second pressure gauge 8, the sixth valve 323 and the controller are conventional existing technologies and will not be described in detail here.

[0042] In this embodiment, if Figure 1 As shown, the pressurized energy storage component 3 also includes a first liquid level gauge 33 and a seventh valve 34 and an eighth valve 35 arranged in sequence along the conveying path, the seventh valve 34 is a check valve, the eighth valve 35 is a flow regulating valve, the first liquid level gauge 33 is arranged on the energy storage tank 31, the inlet of the seventh valve 34 is connected to the outlet of the infusion component 2, the outlet of the eighth valve 35 is connected to the inlet of the energy storage tank 31, and the first liquid level gauge 33 is used to obtain the liquid level information in the energy storage tank 31 to adjust the opening of the eighth valve 35 according to the liquid level information.

[0043] Specifically, the eighth valve 35 and the first liquid level meter 33 are both electrically connected to the controller, so that the controller can control the opening of the eighth valve 35 according to the liquid level information obtained by the first liquid level meter 33. The connection mode and working principle of the first liquid level meter 33, the eighth valve 35 and the controller are conventional prior art and will not be described in detail here.

[0044] It is understandable that by providing the seventh valve 34, it is possible to prevent the liquid entering the energy storage tank 31 from flowing back and causing damage to the conveying assembly. According to the liquid level information in the energy storage tank 31 obtained by the first liquid level meter 33, it is possible to adjust the opening of the eighth valve 35 in time, thereby adjusting the liquid flow entering the energy storage tank 31, so that the liquid supply in the energy storage tank 31 can meet the needs of the liquid replenishment terminal 15, which is conducive to the stable operation of the system.

[0045] In this embodiment, if Figure 1 As shown, the liquid supply system also includes a second liquid discharge pipe and a thirteenth valve 9. The liquid inlet of the second liquid discharge pipeline is connected to the pipeline between the infusion component 2 and the seventh valve 34, and the thirteenth valve 9 is arranged on the second liquid discharge pipeline.

[0046] For example, the thirteenth valve 9 may be a manual valve so as to be reliably opened or closed in an emergency.

[0047] It is understandable that when the liquid supply system stops working, the liquid in the pipeline between the infusion component 2 and the pressurized energy storage component 3 can be discharged by opening the thirteenth valve 9.

[0048] In this embodiment, if Figure 1 As shown, the liquid supply system also includes a ninth valve 10 and a flow meter 11 which are sequentially arranged along the conveying path. The ninth valve 10 is a flow regulating valve. The inlet of the ninth valve 10 is connected to the inlet of the energy storage tank 31. The flow meter 11 is arranged on the pipeline between the ninth valve 10 and the liquid replenishment terminal 15 to control the opening of the ninth valve 10 according to the flow information obtained by the flow meter 11.

[0049] It should be noted that, by providing the flow meter 11 , it is possible to easily obtain the flow information of the liquid outlet of the energy storage tank 31 , so as to adjust the liquid flow output by the energy storage tank 31 according to the requirements of the liquid replenishment terminal 15 .

[0050] In this embodiment, if Figure 1 As shown, the liquid supply system further includes a fourteenth valve 14, the inlet of the fourteenth valve 14 is connected to the liquid outlet of the energy storage tank 31, and the outlet of the fourteenth valve 14 is connected to the inlet of the ninth valve 10. For example, the fourteenth valve 14 is a manual valve, so that the energy storage tank 31 and the liquid replenishment terminal 15 can be disconnected in a timely and reliable manner in an emergency.

[0051] It can be understood that, by providing the fourteenth valve 14 , it is possible to facilitate the disconnection between the energy storage tank 31 and the liquid replenishment terminal 15 as needed.

[0052] In this embodiment, if Figure 1 As shown, the liquid supply system also includes a liquid return pipeline 12 and a tenth valve 13. The inlet of the liquid return pipeline 12 is connected to the outlet of the energy storage tank 31, the liquid outlet of the liquid return pipeline 12 is connected to the liquid inlet of the liquid storage tank 1, and the tenth valve 13 is arranged on the liquid return pipeline 12.

[0053] Specifically, the tenth valve 13 is a flow regulating valve, and the opening of the tenth valve 13 can be controlled according to the flow information obtained by the flow meter 11 .

[0054] It can be understood that by setting the return liquid pipeline 12 and the tenth valve 13, the opening of the tenth valve 13 can be adjusted according to the water demand of the liquid replenishment terminal 15, so that when the liquid flow entering the liquid replenishment terminal 15 is too large or the liquid replenishment terminal 15 does not need liquid replenishment, the water in the energy storage tank 31 and the water replenishment terminal can be returned to the liquid storage tank 1 through the return liquid pipeline 12, which is conducive to saving resources while meeting the liquid replenishment demand of the liquid replenishment terminal 15.
