Description

Technical Field

[0001] The invention relates to a spiral coil external ice melting and ice storage device, belonging to the technical field of ice melting devices. Background Art

[0002] The ice storage tank is the core product of the ice storage system, among which the coil ice storage tank is the most common form. The ice melting method can be divided into external ice melting and internal ice melting. During internal ice melting, the high-temperature coolant flowing in the coil exchanges heat with the ice outside the coil, and the ice layer melts from the inside to the outside; during external ice melting, the air conditioning return water directly enters the ice storage tank and flows through the outer surface of the ice layer for heat exchange, and the ice layer melts from the outside to the inside. Large ice storage systems mostly use external ice melting.

[0003] Currently, for ice melting outside the coil, there is a problem of uneven water flow distribution, which leads to low ice melting heat exchange efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a spiral coil external ice melting and ice storage device, which solves the problem of low ice melting heat exchange efficiency for coil external ice melting in the prior art.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a spiral coil external ice melting and ice storage device, comprising a cylindrical ice storage tank, a water inlet main pipe is arranged at the upper part, and a water outlet main pipe is arranged at the lower part, the water inlet main pipe is connected to a water distributor, and the water outlet main pipe is connected to a water collector; a spiral heat exchange coil is arranged inside the cylindrical ice storage tank; an air blowing component is arranged at the bottom of the cylindrical ice storage tank, and the air blowing component is used to blow air into the cylindrical ice storage tank; wherein the water collector and the air blowing component are two concentric annular channels, which are integrally arranged at the bottom of the cylindrical ice storage tank, the water collector is provided with a plurality of connecting holes one, and the air blowing component is provided with a plurality of connecting holes two.

[0006] By adopting the above technical solution, the return water with higher temperature is discharged into the cylindrical ice storage tank again, so that the melting of ice in the cylindrical ice storage tank can be accelerated. At the same time, air flow is blown into the cylindrical ice storage tank through the air blowing component, so that the water flow in the cylindrical ice storage tank is disturbed, and fully contacts with the return water flow, thereby accelerating the heat exchange rate, and making the water flow in the cylindrical ice storage tank contact with the ice body more evenly, thereby increasing the heat exchange area and further promoting the melting of the ice body.

[0007] The present invention is further configured as follows: the first connecting hole is arranged on the bottom plate of the water collector, and the second connecting hole is arranged on the top plate of the air blowing component.

[0008] By adopting the above technical scheme, the connecting hole 1 on the water collector and the connecting hole 2 on the air blowing assembly are arranged in two opposite directions, and when air blowing and drainage are carried out simultaneously, the water flows into the water collector through the connecting hole 1 at the bottom of the water collector under the action of water pressure, and the air flow is blown into the cylindrical ice storage tank from the connecting hole 2 above the air blowing assembly. The air flow automatically floats up after being blown in, and the water flow can be disturbed during the floating process, thereby accelerating the melting of the ice.

[0009] The present invention is further configured as follows: a plurality of support columns are arranged on the bottom plate of the water collector, and the support columns are fixed to the bottom of the cylindrical ice storage tank.

[0010] By adopting the above technical solution, the water collector can be fixed to the bottom of the cylindrical ice storage tank. When the water collector is collecting water, the communication hole 1 at the bottom fits with the bottom surface of the cylindrical ice storage tank to prevent the communication hole 1 from being blocked by the bottom surface of the cylindrical ice storage tank. The bottom plate of the water collector can be separated from the bottom surface of the cylindrical ice storage tank, so that the water flow can smoothly pass through the communication hole 1 and enter the annular inner cavity of the water collector.

[0011] The present invention is further configured as follows: the water distributor includes a drainage pump, the drainage pump is connected to a plurality of supporting pipes, the supporting pipes are connected to a transition pipe, the transition pipe is connected to an annular water distribution pipe, and the annular water distribution pipe is provided with a plurality of water distribution holes.

[0012] By adopting the above technical solution, the return water can be evenly sprayed back into the cylindrical ice storage tank. When the water distributor distributes water, the return water flow in the water inlet main pipe flows into the transition pipe through the support pipe, flows through the transition pipe and is discharged into different annular water distribution pipes, and finally is evenly discharged into the cylindrical ice storage tank through the water distribution pipe, and exchanges heat with the low-temperature liquid in the cylindrical ice tank.

[0013] The present invention is further configured such that: when melting ice, the annular water distribution pipe is located below the water level in the cylindrical ice storage tank.

[0014] By adopting the above technical solution, it is possible to prevent the water in the annular water distribution pipe from flowing back or leaving gaps, so that the return water flow in the return water pipe can be continuously and stably input into the cylindrical ice storage tank.

[0015] The present invention is further configured as follows: the number of the water collectors is at least two, each water collector is concentrically arranged at an equal distance from each other at the bottom of the cylindrical ice storage tank, the water collector is provided with a plug hole one, the water outlet main pipe is plugged into the plug hole one and connects all the water collectors, and a drainage hole one is opened on the water outlet main pipe plugged into the internal section of the water collector, and the drainage hole one is used to connect the annular channel of the water collector with the water outlet main pipe.

[0016] By adopting the above technical solution, all water collectors can be connected in series through a water outlet main pipe, and by opening a drainage hole 1 on the water outlet main pipe, the inner cavity of the annular water collector and the inner cavity of the water outlet main pipe are connected to each other through the drainage hole 1.

[0017] The present invention is further configured as follows: there are at least two air blowing assemblies, each of which is concentrically arranged at an equal distance from each other at the bottom of the cylindrical ice storage tank, the air blowing assembly is provided with a second plug hole, an air blowing pipe is inserted into the second plug hole, and a second drainage hole is opened on the air blowing pipe plugged into the internal section of the air blowing assembly, and the second drainage hole is used to connect the annular channel of the air blowing assembly with the air blowing pipe.

[0018] By adopting the above technical solution, the energy utilization can be optimized by accurately controlling the air volume and distribution of the air blowing pipe, ensuring that each air blowing component can obtain the required air volume, thereby achieving better ice melting effect and reducing energy waste.

[0019] The present invention is further configured as follows: there are at least two plug holes on each water collector, and they are equidistantly arranged on the annular water collector; one end of the water outlet main pipe branches out a number of plug ends equal to the number of the plug holes and connected to the plug holes, and the other end is connected to the water supply pipe of the air conditioner.

[0020] By adopting the above technical solution, water can be evenly distributed from the outlet main pipe to each water collector. This design helps to avoid excessive concentration or loss of water flow on a certain water collector, thereby improving the uniformity of water flow distribution in the entire system.

[0021] The present invention is further configured such that the number of the second plug holes on each air blowing component and the number of the air blowing pipes are both one.

[0022] By adopting the above technical solution, each air blowing component only needs one plug hole 2 to connect the air blowing pipe, which not only reduces the complexity of the components, but also reduces the cost of production and assembly.

[0023] The beneficial effect of the present invention is that, through the arrangement of the air blowing component, air flow can be blown into the cylindrical ice storage tank during ice melting. After the air flow is blown into the bottom of the cylindrical ice storage tank, a large number of bubbles are generated and float upward. During the floating process of the gas, the water body in the entire cylindrical ice storage tank is disturbed, so that the water body in the cylindrical ice storage tank is in a state of motion, which can accelerate the melting of the ice body. At the same time, the water distributor is used to spray a relatively high temperature return water flow into the cylindrical ice storage tank, which can further improve the heat exchange efficiency between the water body and the ice body in the cylindrical ice storage tank.

[0024] By setting the water distributor, the return water flow in the air conditioner can be evenly sprayed into the water body of the cylindrical ice storage tank, so that the return water flow is evenly in contact with the water body in the cylindrical ice storage tank, thereby improving the heat exchange efficiency.

[0025] By arranging the air blowing assembly and the water collector into an integrated structure, the structure of the entire device is made more compact, which can reduce the installation area of ​​the air blowing assembly and the water collector in the cylinder to a certain extent and increase the overall capacity of the cylinder.

[0037] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0038] like Figure 1 As shown, a spiral coil external ice melting and ice storage device includes a cylindrical ice storage tank 1, a water inlet main pipe 2 is arranged at the upper part, and a water outlet main pipe 3 is arranged at the lower part, the water inlet main pipe 2 is connected to a water distributor 4, and the water outlet main pipe 3 is connected to a water collector 5; a spiral heat exchange coil 6 is arranged inside the cylindrical ice storage tank 1; an air blowing component 7 is arranged at the bottom of the cylindrical ice storage tank 1, and the air blowing component 7 is used to blow air into the cylindrical ice storage tank 1; wherein the water collector 5 and the air blowing component 7 are two concentric annular channels, which are integrally arranged at the bottom of the cylindrical ice storage tank 1, and the water collector 5 is provided with a plurality of connecting holes 501, and the air blowing component 7 is provided with a plurality of connecting holes 701.

[0039] Furthermore, two cooling pipes 12 are installed in the middle of the cylindrical ice storage tank 1, and the two ends of the spiral heat exchange coil are respectively connected to the two cooling pipes 12. When the device is storing ice, the cooling agent enters the spiral heat exchange coil through one cooling pipe 12, circulates once, and then flows out from the other cooling pipe 12. In this embodiment, the cooling agent used for ice storage is specifically ethylene glycol solution.

[0040] In this embodiment, the entire ice storage device realizes the circulation of cold source water and hot source water through the coordinated operation of the water distributor 4 and the water collector 5. The ice storage period of the device is generally selected in the late night when the user's electricity demand is low. During the ice storage process, the device closes the water inlet main pipe 2 and the water outlet main pipe 3, and circulates the low-temperature refrigerant in the spiral heat exchange coil, so that the water near the outer wall of the spiral heat exchange coil gradually condenses into ice until the ice thickness on the outer surface of the spiral heat exchange coil reaches the set value, completing the ice storage step. During the ice melting process of the device, the return water flow with a higher temperature flows into the water inlet main pipe 2 through the return water pipe of the air conditioner, is introduced into the water distributor 4 through the water inlet main pipe 2, and then is evenly sprayed into the cylindrical ice storage tank 1 through the water distributor 4. The return water entering the ice storage tank merges with the original low-temperature water in the ice storage tank and continues to flow, and at the same time contacts with the ice body to promote the melting of the ice body. The bottom of the cylindrical ice storage tank 1 collects water with a lower overall temperature through the water collector 5 and flows into the water outlet main pipe 3, and is transported to the air conditioning refrigeration pipe through the water outlet main pipe 3. During the entire ice melting process, the water inflow and water outflow in the cylindrical ice storage tank 1 are always kept equal, so that the cylindrical ice storage tank 1 is always full of water, and the annular water distribution pipe 404 is always immersed in the cylindrical ice storage tank 1, ensuring that the water in the water inlet main pipe 2 can continuously flow into the cylindrical ice storage tank 1. There will be no interruption of flow. In this process, the ice condensed on the spiral heat exchange coil continuously melts into low-temperature water, merges with the water in the cylindrical ice storage tank 1, and is discharged into the water outlet main pipe 3 through the water collector 5.

[0041] During the ice melting process, air is blown into the cylindrical ice storage tank 1 through the air blowing component 7, which can disturb the water flow, so that the water flow in the flowing state and the water flow after the ice body melts are mixed more evenly. The lower temperature water generated after the ice body melts can quickly move away from the ice body under the disturbance of the water flow, thereby increasing the contact probability between the ice body and the higher temperature water body and improving the ice melting efficiency.

[0042] Furthermore, a cylindrical cover is provided on the top of the cylindrical ice storage tank 1 and is not sealed, so that the gas blown into the cylindrical ice storage tank 1 eventually overflows from the top of the cylindrical ice storage tank 1 .

[0043] Further, such as Figure 3 and Figure 5As shown, the communication hole 1 501 is arranged on the bottom plate of the water collector 5, and the communication hole 2 701 is arranged on the top plate of the air blowing assembly 7. The communication hole 1 501 on the water collector 5 and the communication hole 2 701 on the air blowing assembly 7 are arranged in two opposite directions, and when air blowing and drainage are performed simultaneously, water flows into the water collector 5 through the communication hole 1 501 at the bottom of the water collector 5 under the action of water pressure, and air flows into the cylindrical ice storage tank 1 from the communication hole 2 701 above the air blowing assembly 7. After the air flows in, it automatically floats up, and can generate disturbances to the water flow during the floating process, thereby accelerating the melting of the ice body.

[0044] Specifically, the water collector 5 and the air blowing assembly 7 are an integrated structure. By splicing the water collector 5 and the air blowing assembly 7 together and concentrically arranging them at the bottom of the cylindrical ice storage tank 1, the area occupied by the water collector 5 and the air blowing assembly 7 in the cylindrical ice storage tank 1 can be saved to a certain extent, thereby making the cylindrical ice storage tank 1 have a larger available space.

[0045] In this embodiment, the water collector 5 is an annular hexagonal shape, and is composed of six through grooves of equal length, each of which is connected to each other to form a drainage channel of the water collector 5. The air blowing assembly 7 fits the annular hexagonal water collector 5 and is arranged in the inner circle of the water collector 5. The air blowing assembly 7 and the water collector 5 share a side plate. That is, the air blowing channel of the air blowing assembly 7 and the drainage channel of the water collector 5 are separated by a side plate.

[0046] In one embodiment, the water collector 5 and the air blowing assembly 7 may also be octagonal.

[0047] like Figure 4 As shown, a plurality of support columns 8 are arranged on the bottom plate of the water collector 5. In this embodiment, the number of support columns 8 is six, which are arranged at the six corners of the water collector 5 respectively. The other end of the support column 8 is fixed to the bottom of the cylindrical ice storage tank 1. The water collector 5 can be fixed to the bottom of the cylindrical ice storage tank 1. When the water collector 5 is collecting water, the connecting hole 1501 at the bottom fits with the bottom surface of the cylindrical ice storage tank 1 to prevent the connecting hole 1501 from being blocked by the bottom surface of the cylindrical ice storage tank 1. The bottom plate of the water collector 5 can be separated from the bottom surface of the cylindrical ice storage tank 1, so that the water flow can smoothly pass through the connecting hole 1501 into the annular inner cavity of the water collector 5.

[0048] like Figure 6As shown, the water distributor 4 includes a drainage pump 401, and the drainage pump 401 is connected to a plurality of support pipes 402, and the support pipes 402 are connected to a transition pipe 403, and the transition pipe 403 is connected to an annular water distribution pipe 404, and the annular water distribution pipe 404 is provided with a plurality of water distribution holes. Through the arrangement of the water distributor 4, the return water can be evenly sprayed back into the cylindrical ice storage tank 1. When the water distributor 4 distributes water, the return water flow in the water inlet main pipe 2 flows into the transition pipe 403 through the support pipe, flows through the transition pipe 403, and is discharged into different annular water distribution pipes, and finally is evenly discharged into the cylindrical ice storage tank 1 through the water distribution pipe, and performs heat exchange with the low-temperature liquid in the cylindrical ice tank.

[0049] Furthermore, one end of the support pipe 402 converges to the drainage pump 401 and is communicated with the drainage pump 401 , and the other end is fixed on the wall surface of the cylindrical ice storage tank 1 .

[0050] By setting the water distribution holes, the return water flow can be evenly sprayed into the cylindrical ice storage tank 1 through the annular water distribution pipe 404, and fully and evenly contact the water in the cylindrical ice storage tank 1, which can effectively improve the heat exchange efficiency of the entire device.

[0051] In this embodiment, the annular water distribution pipe 404 is specifically hexagonal, and when melting ice, the annular water distribution pipe 404 is below the water level in the cylindrical ice storage tank 1. This can prevent the water in the annular water distribution pipe 404 from flowing back or leaving gaps, so that the return water flow in the return pipe can be continuously and stably input into the cylindrical ice storage tank 1.

[0052] In one embodiment, the annular water distribution pipe 404 may also be octagonal.

[0053] like Figure 3 As shown, there are at least two water collectors 5 , and each water collector 5 is concentrically arranged at the bottom of the cylindrical ice storage tank 1 with equal spacing.

[0054] like Figure 4 As shown, the water collector 5 is provided with a plug hole 1 502, the water outlet main pipe 3 is plugged into the plug hole 1 502 and connects all the water collectors 5, and the water outlet main pipe 3 plugged into the inner section of the water collector 5 is provided with a drainage hole 1 301, and the drainage hole 1 301 is used to connect the annular channel of the water collector 5 with the water outlet main pipe 3. Further, there are at least two air blowing components 7, each of which is equidistantly and concentrically arranged at the bottom of the cylindrical ice storage tank 1, and the air blowing component 7 is provided with a plug hole 2 702, and the air blowing pipe 10 is inserted into the plug hole 2 702, and the air blowing pipe 10 plugged into the inner section of the air blowing component 7 is provided with a drainage hole 2, and the drainage hole 2 is used to connect the annular channel of the air blowing component 7 with the air blowing pipe 10.

[0055] Among them, Figure 5 As shown, the number of drainage holes 1 301 provided on the water outlet main pipe 3 is one less than the number of water collectors 5, and the end of the water outlet main pipe 3 is plugged into the water collector 5 arranged at the innermost circle of the bottom of the cylindrical ice storage tank 1, and the end opening is directly connected to the inner cavity channel of the water collector 5. Similarly, the number of drainage holes 2 provided on the air blowing pipe 10 is one less than the number of the air blowing assembly 7, and the end of the air blowing pipe 10 is plugged into the air blowing assembly 7 arranged at the innermost circle of the bottom of the cylindrical ice storage tank 1, and the end opening is directly connected to the inner cavity channel of the air blowing assembly 7.

[0056] Simplified piping layout also helps improve system reliability and stability, reducing potential leak points and sources of failure.

[0057] In this embodiment, the number of the plug holes 1 502 on each water collector 5 is at least two, and they are equidistantly arranged on the annular water collector 5, so that the water outlet main pipe 3 can be connected to the plug holes 1 502 on the water collector 5 through different numbers of plug ends according to actual needs. Through the plug holes 1 502 equidistantly arranged on the circumference, the water outlet main pipe 3 can distribute water flow to each water collector 5 more evenly, thereby ensuring that the water flow distribution in the air conditioning system is more reasonable, reducing the phenomenon of local overheating or overcooling, and improving the overall efficiency and comfort of the air conditioning system. The plug ends equal to the number of the plug holes 1 502 are separated from one end of the water outlet main pipe 3 and connected to the plug holes 1 502, and the other end is connected to the water supply pipe of the air conditioner. The number of the plug holes 2 702 on each air blowing component 7 is the same as the number of the air blowing pipe 10.

[0058] The plug-in connection greatly simplifies the installation process, reduces the complex pipe layout and number of joints required in traditional connection methods, and reduces installation costs and time. At the same time, this design is also convenient for subsequent maintenance and repair work, and the plug-in end can be easily disconnected and reconnected.

[0059] In one embodiment, Figure 7 As shown, at least six floating nozzles 9 are equidistantly arranged on each annular water distribution pipe 404, and the return water in the annular water distribution pipe 404 is sprayed out through the floating nozzles 9. The larger the range encircled by the annular water distribution pipe 404, the more floating nozzles 9 are installed on the upper part thereof.

[0060] Specifically, the lower end of the annular water distribution pipe 404 is extended with a telescopic sleeve 11, and the floating nozzle 9 is slidably connected in the telescopic sleeve 11. The floating nozzle 9 includes a sliding pipe 903 that is slidably connected in the telescopic sleeve 11, and a float 902 is fixedly connected to the sliding pipe 903, and a sinking member 901 is fitted at the lower end of the float 902. When the entire floating nozzle 9 is in use, the weight of the sinking member 901 causes a part of the floating nozzle 9 to sink below the water level of the cylindrical ice storage tank 1, and at the same time, under the action of the float 902, the floating nozzle 9 is kept from completely sinking into the water in the cylindrical ice storage tank 1, so that the return water flow in the annular water distribution pipe 404 is connected to the water in the cylindrical ice storage tank 1, and the return water flow can be continuously and evenly passed into the water without interruption.

[0061] After the return water flows into the annular water distribution pipe 404, it passes through the telescopic sleeve 11 and enters the sliding pipe 903. Under the guidance of the sliding pipe 903, it smoothly flows into the cylindrical ice storage tank 1. During the whole process, the floating nozzle 9 will not be affected by the recoil force generated when the water flow is sprayed out. The entire floating nozzle 9 only plays a guiding role to ensure that the water flow in the annular water distribution pipe 404 will not be interrupted during water distribution.

[0062] Furthermore, in the present embodiment, the float 902 is hollow and filled with gas, the sinker 901 has a cavity inside, and the cavity is filled with an appropriate amount of high-density solid material, which may be pebbles or stainless steel beads. By reasonably controlling the weight of the sinker 901, the entire floating nozzle 9 can float on the water surface, and the drainage port of the floating nozzle 9 is immersed under the water surface. The entire floating nozzle 9 can rise and fall with the rise and fall of the water surface, so that the drainage port of the floating nozzle 9 always remains below the water surface.

[0063] By setting the floating nozzle 9, the flow control between the water inlet pipe and the water outlet pipe can be more relaxed, and there is no need to accurately control the water output to be consistent with the water inlet. When the water output is greater than the water inlet, causing the liquid level in the cylindrical ice storage tank 1 to drop, the floating nozzle 9 also drops accordingly. When the water output is less than the water inlet, causing the liquid level to rise, the floating nozzle 9 also rises accordingly.

[0064] In one embodiment, the number of floating nozzles 9 provided on each annular water distribution pipe 404 may also be twelve, eighteen or twenty-four.

[0065] Further, such as Figure 8 and Fig. 9 As shown, a step slide groove is provided on the sliding pipe 903, and a contact sensor 1 904 and a contact sensor 2 905 are respectively provided at the upper and lower ends of the step slide groove.

[0066] By setting the contact sensor 1 904 and the contact sensor 2 905, when the water level in the cylindrical ice storage tank 1 drops too much, the floating nozzle 9 drops to the bottom, the contact sensor 1 904 contacts the telescopic sleeve 11, and triggers an alarm, thereby reminding the staff to manually control the water level in the cylindrical ice storage tank 1, and to increase the water level in the cylindrical ice storage tank 1 by reasonably reducing the water output of the water outlet main pipe 3 or increasing the water input of the water inlet main pipe 2. When the water level in the cylindrical ice storage tank 1 rises too much, the floating nozzle 9 rises to the top, the contact sensor 2 905 contacts the telescopic sleeve 11, and triggers an alarm, reminding the staff to adjust the water level in the cylindrical ice storage tank 1 to prevent water from overflowing.

[0067] In one embodiment, if Fig.10 As shown, a cylindrical baffle is fixedly installed in the middle of the cylindrical ice storage tank 1, wherein two cooling pipes 12 are installed in the inner circle of the cylindrical baffle, a supporting pipe 402 passes through the wall of the cylindrical baffle and is connected to the drainage pump 401, and a water inlet main pipe 2 passes through the wall of the cylindrical baffle and is connected to the drainage pump 401. In this embodiment, the diameter of the cylindrical baffle is greater than one meter, which can accommodate workers to pass through, and construction workers can go down to the bottom of the cylindrical ice storage tank 1 through the drainage baffle to inspect the entire device.

[0068] Working principle:

[0069] When the device stores ice, the water inlet main pipe 2 and the water outlet main pipe 3 are closed, and the refrigerant is introduced into the spiral heat exchange coil through the refrigerant pipe 12. The refrigerant flows in the spiral heat exchange coil and releases the cold source, so that the water near the outer wall of the spiral coil gradually condenses into ice. When the ice condenses to the set target value, the introduction of the refrigerant is stopped.

[0070] When the device melts ice, by opening the water inlet main pipe 2 and the water outlet main pipe 3, the water inlet main pipe 2 is connected to the water distributor 4 and the return water pipe of the air conditioner respectively. Since the temperature of the return water flow is higher than the water temperature in the cylindrical ice storage tank 1, the return water flow is discharged into the cylindrical ice storage tank 1 through the annular water distribution pipe, and gradually mixes with the water in the cylindrical ice storage tank 1, and contacts with the ice condensed on the spiral heat exchange coil, promoting the melting of the ice body, and mixing with the low-temperature water after the ice body melts, and the temperature is lowered again. The low-temperature water flow enters the inner cavity of the water collector 5 through the connecting hole 501 on the water collector 5. Through continuous circulation, the ice body can contact the water flow with a higher temperature, accelerate the melting of the ice body, and improve the efficiency of heat exchange.

[0071] When uneven ice melting occurs, air is blown into the cylindrical ice storage tank 1 through the air blowing component 7. After the air is blown into the water, bubbles are generated and automatically float up. The water body can be disturbed during the floating process, so that the return water flow and the water in the cylindrical ice storage tank 1 are mixed faster, and the actively flowing water flow can further promote the melting of the ice body.

[0072] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
