Description

Technical Field

[0001] The invention relates to the technical field of cooling liquid supply, and in particular to a cooling liquid dynamic circulation supply method and cooling liquid supply equipment. Background Art

[0002] In industrial production, some high-speed equipment needs to continuously use coolant to cool it down during the working process to prevent production and safety accidents caused by excessive temperature of the equipment; referring to the field of solid-state additive manufacturing, when preparing large-size deposition components, the existing coolant supply method is difficult to ensure that the water storage capacity of the equipment meets the long-term preparation process, which directly leads to heat accumulation of the components and affects the mechanical properties; in order to ensure the continuous supply of coolant, reduce the use of new water and increase the reuse rate of existing coolant, so as to achieve the purpose of energy saving and consumption reduction, water supply equipment should use circulating water as much as possible. Therefore, the circulation system of coolant is very common and important in scientific research experiments and actual production.

[0003] Referring to the current common coolant circulation supply methods, it can be seen that most of them use cooling towers to supply liquid to achieve the purpose of recycling. However, such uninterrupted activation of cooling towers consumes a lot of energy and has a very high operating cost. Moreover, since the equipment is in a high-speed rotation state, a large amount of coolant will splash during the cooling process, greatly reducing the secondary utilization rate. In addition, the existing circulating water supply method causes the corresponding equipment used to be generally large in size, with slow response and cumbersome daily maintenance. Therefore, it is necessary to propose a dynamic circulation supply method for coolant with high operability and fast response. Summary of the invention

[0045] Embodiment 1

[0046] In an embodiment of the present application, a method for dynamically circulating and supplying a coolant is provided to continuously provide coolant to cool a module to be cooled, for example, to cool a processing position in the field of solid-state additive manufacturing.

[0047] In an optional embodiment, the coolant is controlled to flow to at least one of the multiple containers; then the liquid level information in the container receiving the coolant is obtained to adjust the liquid inlet and discharge states of the multiple containers according to the liquid level information in the container, so that the multiple containers cooperate to alternately supply liquid to the module to be cooled.

[0048] In this embodiment, the module to be cooled is continuously cooled by the coolant by alternately and continuously supplying liquid to the module to be cooled through multiple containers; the alternating liquid supply should be understood as, for example, when a first preset liquid level is reached in one of the multiple containers, liquid is supplied to the module to be cooled, and at least another one of the multiple containers is in a non-liquid supply state (for example, filling with liquid or maintaining the existing liquid level) at this time; when the coolant in one container is discharged to make its liquid level reach a second preset liquid level, the liquid can be discharged from another container whose liquid level reaches the first preset liquid level. Such alternating liquid supply effectively solves the volume limitation of the water storage container and ensures the circulating supply of cooling water, which greatly meets the continuous demand for cooling water and other solutions in scientific research experiments and actual industrial production processes; improves the safety and reliability of the circulating water supply system and plays a role in saving resources; it should be understood that the first preset liquid level and the second preset liquid level here are only for the convenience of explaining the conceived concept and should not be used as an interpretation of the scope of protection.

[0049] In an optional embodiment, for example, the multiple containers are reduced to two, namely a first container 100 and a second container 200. The continuous supply of the coolant can be completed by setting up a minimum number of containers, which can effectively reduce the size of the equipment and facilitate daily repair and maintenance.

[0050] In an optional embodiment, a plurality of trigger liquid levels are respectively set in the first container 100 and the second container 200 in sequence; the liquid level information in the first container 100 and the second container 200 is obtained, and the liquid inlet and outlet states of the first container 100 and the second container 200 are adjusted according to different trigger liquid levels.

[0051] In this embodiment, by sequentially setting a plurality of trigger liquid levels in the first container 100 and the second container 200, respectively, the trigger liquid levels are raised sequentially. When the first container 100 or the second container 200 is at the corresponding trigger liquid level, the first container 100 is controlled to be in a liquid-intake state or a liquid-discharge state, and the second container 200 is controlled to be in a liquid-intake state or a liquid-discharge state. Of course, the liquid-intake and liquid-discharge states here should not be understood as having only two states, namely, liquid-intake or liquid-discharge, but may also be a liquid-level holding state, that is, neither liquid-intake nor liquid-discharge. The purpose is only to continuously supply coolant to the cooling module by alternately draining the first container 100 and the second container 200. For example, when the first container 100 is draining, the second container 200 may be inlet or in a liquid-level holding state. It is understandable that the same is true for the second container 200.

[0052] In an optional embodiment, the coolant enters the container in such a way that a negative pressure is created in the container, and then a corresponding liquid inlet valve is opened to allow the coolant to enter the corresponding container. Here, the device used to maintain the negative pressure in the container may be a vacuum pump, which extracts gas from the corresponding container to make it a negative pressure, and opens the corresponding liquid inlet valve to achieve the effect of extracting the coolant (this coolant refers to a gas-liquid mixture) into the corresponding container. For example, a first vacuum pump 340 is connected to the first container 100, and the first vacuum pump 340 extracts the first container 100 into a negative pressure, and opens the liquid inlet valve, at which time the coolant enters the first container 100 from the liquid inlet valve. A second vacuum pump 350 is connected to the second container 200, and the working process is the same as the liquid entry process of the first container 100. The reason why a vacuum pump is used instead of an ordinary booster pump, a diaphragm pump, etc. is because these pumps are only suitable for extracting pure liquids. When gas is mixed in the liquid, it will cause a loss of pressure, and thus the gas-liquid mixture cannot be smoothly extracted. The coolant extracted in the embodiment of the present application may specifically refer to a gas-liquid mixture.

[0053] In an optional embodiment, during the process of alternating liquid supply, the liquid inlet state and the liquid discharge state in a single container are controlled to be mutually exclusive.

[0054] In this embodiment, when liquid is alternately supplied to the modules to be cooled, the liquid filling state and the liquid discharge state in a single container should be made to repel each other; for example, when liquid is filled into the first container 100, liquid is not discharged; when liquid is discharged from the first container 100, liquid is not filled; the same is true for the second container 200; this is because when there is a negative pressure in the container, drainage cannot proceed smoothly at this time; therefore, in order to ensure the normal operation of the entire cooling liquid circulation supply process, liquid filling and liquid discharge cannot be carried out at the same time.

[0055] In an optional embodiment, during the process of alternating liquid supply, the drainage states of the first container 100 and the second container 200 are controlled to be mutually exclusive; for example, when the first container 100 is draining, the second container 200 is not draining; when the second container 200 is draining, the first container 100 is not draining; a prerequisite here is that the drainage states of the first container 100 and the second container 200 are controlled to be mutually exclusive only during the process of alternating liquid supply; for example, when it is necessary to stop the alternating liquid supply process, it may be necessary for the first container 100 and the second container 200 to drain at the same time.

[0056] In an optional embodiment, setting a plurality of trigger liquid levels in the first container 100 and the second container 200 in sequence respectively comprises:

[0057] Three trigger liquid levels A1, A2, and A3 are set in sequence in the first container 100; three liquid levels B1, B2, and B3 are set in sequence in the second container 200; by setting three trigger liquid levels in the first container 100 and the second container 200 respectively, the process of alternately supplying cooling liquid to the module to be cooled by the two containers can be completed.

[0058] In an optional implementation, multiple containers cooperate to alternately supply liquid to the module to be cooled, and the liquid supply step includes:

[0059] S100, open the first liquid inlet valve 310, the first vacuum pump 340 and the first exhaust valve 110 of the first container 100 to allow liquid to enter the first container 100; at this time, other valves and pumps are all closed, and the second container 200 is empty; it is understandable that before S100, the vacuum pump can be opened in advance as needed to draw the interior of the container that needs to be filled with liquid into a negative pressure state to facilitate liquid entry.

[0062] Optionally, determine whether the liquid level in the first container 100 is not lower than A3, and at the same time obtain the liquid level information in the second container 200 through the second liquid level monitoring component 800 to determine whether the liquid level in the second container 200 is not lower than B2. If one of the conditions is not met, continue to add liquid; if one of the conditions is met, control the closing of the first liquid inlet valve 310 and the first air exhaust valve 110, and stop adding liquid to the first container 100; at the same time, control the opening of the first water pump 410, the first water pumping valve 420, the first water outlet valve 430, and the first air valve 130 to break the negative pressure state in the first container 100, the first container 100 starts to discharge liquid, and the second container 200 can continue to add liquid.

[0063] S400, obtain the liquid level information in the first container 100 through the first liquid level monitoring component 700, and determine whether the liquid level in the first container 100 reaches or is lower than A1. If not, continue to drain the liquid; if so, stop draining the liquid, and close the first water pump 410, the first water pump valve 420, the first water outlet valve 430, and the first air valve 130.

[0064] S410, opening the first air extraction valve 110 to balance the internal and external air pressures of the first container 100, and judging whether it is balanced based on the value of the first pressure detection component 120, which needs to be less than a standard atmospheric pressure, i.e., 0.1013 MPa.

[0065] S500, obtain the liquid level information in the second container 200 through the second liquid level component, and determine whether the liquid level in the second container 200 is not lower than B2. If not, continue to add liquid; if so, keep adding liquid while controlling the liquid addition to the first container 100, that is, open the first liquid inlet valve 310 and the first air extraction valve 110.

[0066] S600, determine whether the liquid level in the first container 100 is not lower than A2, and at the same time determine whether the liquid level in the second container 200 is not lower than B3. If any of the conditions is not met, continue to add liquid; if one of the conditions is met, control the second container 200 to stop adding liquid and drain the liquid, that is, close the second air extraction valve 210 and the second liquid inlet valve 320; at the same time, open the second water pump 520, the second water extraction valve 520, the second water outlet valve 530, and the second air valve 230.

[0067] S700, determine whether the liquid level in the second container 200 reaches or is lower than B1, if not, continue to drain the liquid; if yes, stop draining the liquid, that is, close the second pumping pump 520, the second pumping valve 520, the second outlet valve 530, and the second air valve 230.

[0069] S800, determine whether the liquid level in the first container 100 is not lower than A2, if not, continue to add liquid, if so, keep adding liquid while controlling the second container 200 to add liquid, that is, open the second air extraction valve 210 and the second liquid inlet valve 320.

[0070] S900, determine whether the liquid level in the first container 100 is not lower than A3, and at the same time determine whether the liquid level in the second container 200 is not lower than B2.

[0072] When it is necessary to stop the above circulating liquid supply process, the first liquid inlet valve and the second liquid inlet valve can be closed, and the first water pump 410 and the second water pump 520 can be turned on to discharge the coolant in the first container 100 and the second container 200 to the specified liquid level, and then the coolant can be cut off to shut down the equipment.

[0073] Example 2

[0074] In this embodiment, a cooling liquid supply device is also provided to implement the above-mentioned embodiments and preferred embodiments, which have been described and will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0075] A cooling liquid supply device comprises a first container 100 and a second container 200, wherein the second container 200 and the first container 100 are arranged side by side; the first container 100 and the second container 200 are both connected to a liquid supply component 300; the first container 100 is connected to a first drain component 400 for extracting and discharging liquid in the first container 100 when necessary; the second container 200 is connected to a second drain component 500 for extracting and discharging liquid in the second container 200 when necessary; the first drain component 400 and the second drain component 500 are commonly connected to a liquid outlet pipe 600 for discharging the liquid in the first container 100 and the second container 200 to the liquid outlet pipe 600; wherein the first drain component 400 and the second drain component 500 work alternately to alternately extract the liquid in the first container 100 and the second container 200 to flow to the liquid outlet pipe 600.

[0076] In this embodiment, the second container 200 is arranged side by side with the first container 100 and both are connected to the liquid supply component 300. The liquid supply component 300 can supply liquid to the first container 100 and / or the second container 200. The liquid can be water, oil or other liquid suitable for cooling; the first liquid discharge component 400 can extract the liquid in the first container 100 and discharge it to the liquid outlet pipe 600; the second liquid discharge component 500 can extract the liquid in the second container 200 and discharge it to the liquid outlet pipe 600; the liquid outlet pipe 600 is connected to the cooling liquid demand module; the first liquid discharge component 400 and the second liquid discharge component 500 work alternately to alternately extract the liquid in the first container 100 and the second container 200 to flow to the liquid outlet pipe 600, and by alternately supplying liquid to the liquid outlet pipe 600, the volume limitation of the liquid storage container itself can be eliminated, and the cooling liquid can be continuously supplied, thereby meeting the continuous demand for cooling liquid in scientific research experiments and actual industrial production processes; and the safety and reliability of the supply of the circulating water system are improved and the resource saving effect is played.

[0077] In an optional embodiment, the liquid supply component 300 includes a first vacuum pump 340 and a second vacuum pump 350. The first container 100 is connected to the first vacuum pump 340 to extract negative pressure from the first container 100; the second container 200 is connected to the second vacuum pump 350 to extract negative pressure from the second container 200; in one of the use states, the first vacuum pump 340 is used to evacuate the first container 100 to a negative pressure state, thereby extracting liquid from the liquid supply pipe of the liquid supply component 300 into the first container 100; the working principle of the second vacuum pump 350 is similar to that of the first vacuum pump 350, which will not be repeated here; the choice of a vacuum pump as the power component of the liquid supply component 300 here is a better choice, because if the booster pump or diaphragm pump extracts a gas-liquid mixture during use, it will cause decompression and poor liquid extraction effect.

[0078] In an optional embodiment, before the liquid is introduced, the first vacuum pump 340 or the second vacuum pump 350 may be used to make the gas pressure in the first container 100 or the second container 200 lower than the standard atmospheric pressure.
