DETAILED DESCRIPTION

[0031] The application will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the application, and the changes made by those skilled in the art in structure, method, or function based on these embodiments are included in the protection scope of the application.

[0032] In various diagrams of the application, the size of some structures or parts may be exaggerated relative to other structures or parts for ease of illustration, and therefore only serve to illustrate the basic structure of the subject matter of the application.

[0033] The purpose of the present application is to provide a supercooling removal device 100 and an ice making system, aiming to solve the problems of low ice making efficiency, insufficient ice-water separation, poor system stability, etc. in the prior art. Specifically, the present application provides a supercooling removal device 100 that can quickly remove the supercooling state of supercooled water and crystallize into ice, while achieving effective separation of ice and water. The present application also provides an integrated ice making system based on the supercooling removal device 100, which realizes the complete process flow from the manufacture of supercooled water to the formation of ice slurry and then to the separation of ice and water, thereby improving the ice making efficiency and system stability.

[0034] Please refer to Figures 1 to 11 The supercooling removal device 100 includes a shell 1, a filter screen 2, and an ice discharge assembly 3.

[0035] The shell 1 is used to provide a spatial environment for the supercooling water to remove the supercooling state. The shell 1 includes a containing cavity 11, an inlet 12 for the supercooled water to enter the containing cavity 11, and an outlet 13 for the water to remove the supercooling state to exit the containing cavity 11.

[0036] Please refer to Figure 2 , Figure 5 , Figure 6 , and Figure 11 The filter screen 2 is located in the containing cavity 11, and the bottom of the filter screen 2 is spaced apart from the bottom of the containing cavity 11. Water can fall from the filter screen 2 to the bottom of the containing cavity 11, but ice crystals, or ice particles, or ice slurry, or ice blocks, etc. cannot pass through the filter screen 2, thereby being retained above the filter screen 2, i.e. the top of the containing cavity 11.

[0037] The supercooled water enters the accommodating cavity 11 and especially touches the filter screen 2, and the supercooled state is released to form ice crystals, or ice particles, or ice slurry, etc., which may be mixed with part of the water. The water falls through the filter screen 2 to the bottom of the accommodating cavity 11 to realize the separation of the ice crystals, or ice particles, or ice slurry, etc.

[0038] Please refer to Figures 1-5 、 Figure 11 The ice discharging assembly 3 is used to transport the separated ice slurry, etc. to the outside of the device. The ice discharging assembly 3 includes a conveying pipe 31 fixed to the shell 1, an ice pushing mechanism 32 located in the conveying pipe 31, and a driving unit (not shown) driving the ice pushing mechanism to discharge ice.

[0039] The conveying pipe 31 has a first port 311 and a second port 312 distributed along the axial direction thereof, the first port 311 is located on the side of the filter screen 2 away from the bottom of the accommodating cavity 11, and the second port 312 is located on the outside of the shell 1. When ice discharging is required, the driving unit is started to drive the ice discharging mechanism 32 to work to move the ice in the accommodating cavity 11 from the first port 311 to the second port 312, so as to discharge it out of the shell 1.

[0040] The specific structure of the supercooling release device 100 in the application will be described in detail below in combination with the accompanying Figures 1 to 11 The specific structure of the supercooling release device 100 in the application will be described in detail below in combination with the accompanying

[0041] The shell 1 is a heat preservation shell, which aims to maintain the temperature in the accommodating cavity 11 stable to avoid the influence of the ambient temperature on the supercooled water, ensure that the supercooled water will not release the supercooled state or the temperature will not rise in advance before entering the accommodating cavity 11 due to the change of the ambient temperature, and also ensure that the ice slurry, etc. will not melt.

[0042] The heat preservation shell can be an insulating layer added to the outer surface, inner surface or inside of the shell 1, which includes but is not limited to a vacuum heat insulation plate, a polyurethane foaming layer, etc. As shown in Figures 6 to 11 The heat preservation shell can also be a vacuum cavity 10 arranged in the shell 1 to improve the heat preservation effect.

[0043] The shell 1 includes a cylinder 14 with an upward opening and a cover 15 opening or closing the opening, and the cylinder 14 and the cover 15 form the accommodating cavity 11. The matching structure of the cylinder 14 and the cover 15 facilitates the daily cleaning and maintenance of the device, while ensuring the sealing of the accommodating cavity 11. The cylinder 14 and the cover 15 are any one of the heat preservation shells as described above.

[0044] The inlet 12 is located on the cover 15, so that the cover 15 can be connected with the outlet of the supercooling water pipeline or heat exchanger. In this way, the temperature rise of the supercooling water caused by the ambient temperature during falling can be reduced, and the supercooling water enters the containing cavity 11 from top to bottom, which is more conducive to ice-water separation.

[0045] The inlet 12 is located in the middle of the cover 15; it ensures that the supercooling water directly impacts the ice crystals, or ice particles, or ice slurry in the central area of the filter screen 2, enhancing the effect of relieving the supercooling state.

[0046] The barrel 14 includes a bottom wall 141 and a side wall 142, and the outlet 13 is arranged on the bottom wall 141 and can smoothly discharge water. Preferably, the outlet 13 is arranged in the middle of the bottom wall 141, which is conducive to uniform outflow of separated water and improves the water recovery efficiency.

[0047] In an embodiment, as shown in Figure 5 , Figure 8 and Figure 11 , the inner wall surface (the surface facing the containing cavity 11) of the bottom wall 141 is inclined downward from the side wall 142 to the outlet 13, that is, the outlet 13 is at the lowest point of the bottom wall 141, which is conducive to water flow to the outlet 13 and facilitates rapid and sufficient discharge of water in the containing cavity 11. Specifically, the downward inclination angle is 1° to 5°, for example, 3°±1° downward inclination.

[0048] In addition, the inlet 12 is connected to the outlet of the supercooling water pipeline or heat exchanger through a water inlet pipe 121. The outlet 13 discharges water outward through a water outlet pipe 131. The water inlet pipe 121 and the water outlet pipe 131 are both designed to be heat-insulated, further avoiding interference of the external temperature on the water temperature in the system.

[0049] Please refer to Figure 2 , Figure 5 , Figure 6 , and Figure 11 , the filter screen 2 is conical, and the diameter of the filter screen 2 gradually decreases from the top to the bottom. The conical structure makes the supercooling water entering the containing cavity 11 relieve the supercooling state by impacting the conical filter screen 2, and the conical filter screen 2 concentrates the generated ice slurry to the middle position, while further making the water in the ice slurry flow downward, which is conducive to ice-water separation. The conical filter screen 2 concentrates the ice crystals, or ice particles, or ice slurry to the middle position, and the ice crystals, or ice particles, or ice slurry provide “ice nuclei” for the supercooling water falling on them, which can improve the efficiency of relieving the supercooling state. This conical design enhances the separation effect of the ice slurry and water, improves the efficiency of relieving the supercooling state, and further improves the ice-making efficiency and the quality of ice.

[0050] The bottom of the filter screen 2 is spaced apart from the bottom of the accommodating cavity 11 to form a water collection area, so that the water after being relieved from the supercooling state can be separated from the ice and discharged through the outlet 13.

[0051] The filter screen 2 is provided with a through hole 21 through which the conveying pipe 31 passes, the conveying pipe 31 passes through the filter screen 2, and the first port 311 is located in the filter screen 2, so that the ice in the filter screen 2 can be discharged in time.

[0052] In an embodiment, the first port 311 does not exceed the central axis L of the filter screen 2, that is, the first port 311 is located between the central axis L of the filter screen 2 and the through hole 21, or the first port 311 is flush with the central axis L of the filter screen 2. That is, the size of the conveying pipe 31 extending into the filter screen 2 does not exceed the radius of the filter screen 2 at the position of the plane (perpendicular to the central axis L) where the through hole 21 is located. This design enables the conveying pipe 31 to more effectively discharge the ice slurry concentrated in the central region of the filter screen 2 while reducing interference with the filtering function of the filter screen 2.

[0053] Preferably, the central axis L of the filter screen 2 coincides with the central axis of the cylinder body 14. The first port 311 does not exceed the central axis of the cylinder body 14.

[0054] A portion of the supercooled water entering through the inlet 12 may impact on the first port 311 of the conveying pipe 31 to form ice slurry or even accumulate to form an ice column. In a preferred embodiment, the height difference H1 between the conveying pipe 31 and the inlet 12 is not less than 200 mm. For example, not less than 220 mm, or not less than 250 mm, or not less than 300 mm. This is to prevent the aforementioned ice column from being too high to affect the water outlet or even cause ice blockage at the inlet 12. The greater the height difference H1, the less the ice column affects the water inlet, and the less likely it is to cause ice blockage.

[0055] The inventors have found that the ice column formed by the supercooled water will break off when it accumulates to a certain height. In combination with the micro-vibration generated when the ice discharging assembly 3 operates, the height difference H1 of not less than 200 mm can ensure that the ice column will not accumulate to the inlet 12.

[0056] In a preferred embodiment, the height difference H2 between the conveying pipe 31 and the bottom of the filter screen 2 is not less than 100 mm. For example, not less than 120 mm, or not less than 150 mm, or not less than 200 mm. This height difference design ensures that the ice slurry at the position of the first port 311 has a low water content (in the form of snow), thereby improving the quality of the discharged ice slurry. The greater the height difference H2, the less liquid water contained in the discharged ice.

[0057] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 11As shown, in some embodiments, the ice pushing mechanism 32 of the ice discharging assembly 3 is a screw rod. The screw rod comprises a rotating shaft 321 extending axially along the conveying pipe 31 and a rotating blade 322 connected to the rotating shaft 321. The driving unit is connected to the rotating shaft to drive the rotating shaft to rotate around its axis, and the rotating blade 322 drives the ice slurry and the like to move from the first port 311 to the second port 312. The generated ice slurry is transported out of the barrel by the screw rod, which can continuously and stably deliver the ice slurry out of the device and improve the ice discharging efficiency.

[0058] The rotating blade 322 is close to the inner wall of the conveying pipe 31 away from the outer edge, which prevents the ice slurry from flowing back during the conveying process and improves the conveying efficiency.

[0059] The screw rod exceeds the first port 311 from the second end to the first end. The design that the screw rod exceeds the first port 311 makes the front end of the screw rod exceed the center of the barrel 14, which can agitate the ice layer to prevent the ice column from being too high and avoid the system from being blocked due to excessive ice accumulation. Specifically, when the height of the ice slurry and the like in the filter screen 2 exceeds 100 mm or more than 100 mm of the conveying pipe 31, the screw rod is started to discharge ice outward.

[0060] In the present application, the driving unit includes but is not limited to a motor, a hand crank and the like, as long as it can drive the rotating shaft 321 to rotate.

[0061] In other embodiments, as shown in Figure 12 , the ice pushing mechanism 32 is a screw rod. The screw rod comprises a push-pull rod 320, a rotating shaft 321 connected to the push-pull rod, and a rotating blade 322 connected to the rotating shaft 321. The rotating shaft 321 extends axially along the conveying pipe 31. The driving unit is connected to the rotating shaft 321 to drive the rotating shaft 321 to rotate around its axis.

[0062] The rotating shaft 321 extends axially along the conveying pipe 31, and the push-pull rod 320 can push the rotating shaft 321 to move axially along the conveying pipe 31, so that the screw rod is retracted from the first port 11 (as shown in Figure 12 (a) of FIG. 3) or extends out of the conveying pipe 31 (as shown in Figure 12 (b) of FIG. 3). When the height of the ice slurry and the like in the filter screen 2 exceeds 100 mm or more than 100 mm of the conveying pipe 31, the screw rod is pushed out of the first port 11 (as shown in Figure 12 (b) of FIG. 3), and the ice is discharged outward in time. When the ice is not needed to be discharged, the screw rod can be retracted into the conveying pipe 31 (as shown in Figure 12 (a) of FIG. 3) to reduce the influence on the subcooled water, the ice slurry and the like; or the screw rod can be kept in the extended state (as shown in Figure 12 (b) of FIG. 3) to start discharging ice outward at any time.

[0063] This push-pull type screw rod can replace the screw rod in the filter screen 2 to control the extension distance of the screw rod, and the ice can be discharged to the maximum extent. Figures 1 to 11

[0064] Through the above structure design, the supercooling removal device 100 can realize efficient removal of the supercooled state of the supercooled water, promote crystallization into ice, and realize full separation of ice water and timely discharge of ice slurry through the combined structure, thereby improving the continuous working capacity and ice making efficiency of the system.

[0065] On the basis of any of the above designs, as shown in Figures 6-8 and Figure 11 The supercooling removal device 100 further comprises a window 4 for observing the water and / or ice in the containing cavity 11. The window 4 is a transparent plate material with a vacuum interlayer inside, such as glass or acrylic plate.

[0066] The window 4 is not higher than the bottom of the ice discharge assembly 3. When it is observed that the liquid level in the containing cavity 11 is higher than the bottom of the ice discharge assembly 3, it indicates that the amount of ice is insufficient or no ice can be discharged, or the amount of water is too high, and the ice discharge should be stopped and the water outlet pipe 131 should be opened to discharge water.

[0067] Preferably, the window 4 is lower than the bottom of the ice discharge assembly 3, and the liquid level can be found when it is lower than the ice discharge assembly 3, so that the water can be discharged in time to avoid affecting the quality of the ice.

[0068] The application also provides an ice making system, which comprises a cooling supply system, a water supply system, a heat exchanger, and the above-mentioned supercooling removal device 100. The cooling supply system provides a cold carrier medium with a temperature lower than the freezing point of water; the water supply system controls the temperature and flow of the water supply; the heat exchanger exchanges heat between the cold carrier medium and the water to form supercooled water; and the supercooling removal device 100 receives the supercooled water and removes the supercooled state to form ice slurry, while realizing ice-water separation and ice slurry transportation.

[0069] When the whole system is working, the supercooled water enters the containing cavity 11 and removes the supercooled state by impacting the conical filter screen 2. The conical filter screen 2 concentrates the generated ice slurry to the middle position, which can improve the efficiency of removing the supercooled state and promote the water in the ice slurry to gather downward, which is beneficial to ice-water separation. The ice discharge assembly 3 connected to the side of the shell 1 transports the generated ice slurry to the outside of the shell 1 through the screw rod, and the water outlet pipe 131 connected to the bottom returns the separated water to the water supply system for recycling, thereby realizing efficient ice making and recycling of resources.

[0070] ​The cooling supply system comprises a first temperature control device for providing a first preset temperature of the cooling medium and a first pump for controlling the flow of the cooling medium. The cooling medium refers to a medium for cooling water, such as refrigerant, non-freezing liquid, etc. The first temperature control device controls the temperature of the cooling medium in a range below the freezing point of water, and the flow of the cooling medium is controlled by the first pump to ensure that the system has sufficient cooling capacity for refrigeration.

[0071] The first preset temperature is lower than the freezing point of water. The first preset temperature is lower than the target temperature of the supercooled water. The temperature difference between the first preset temperature and the target temperature of the supercooled water is not less than 5℃, preferably not less than 7℃, and preferably not less than 10℃. The temperature difference between the first preset temperature and the target temperature of the supercooled water is not more than 15℃, preferably not more than 12℃, and preferably not more than 10℃.

[0072] The water supply system comprises a second pump for controlling the flow of water. In a preferred embodiment, the water supply system further comprises a second temperature control device for providing water at a second preset temperature, which can provide water at a constant temperature.

[0073] The second preset temperature is higher than the freezing point of water. The temperature difference between the second preset temperature and the freezing point of water is not more than 10℃, preferably not more than 7℃, preferably not more than 5℃, and preferably not more than 3℃. The temperature difference is set in this range to keep the water at a temperature close to the freezing point, which facilitates the rapid formation of supercooled water in the heat exchanger and improves the ice-making efficiency. The outlet 13 of the supercooling device is connected to the second temperature control device through the water outlet pipe 131, forming a water circulation system and improving the water resource utilization efficiency.

[0074] The heat exchanger comprises a first fluid passage and a second fluid passage for heat exchange of two fluids. The two ports of the first fluid passage are connected to the cooling supply system, and the water inlet of the second fluid passage is connected to the water supply system. The inlet 12 of the supercooling relief device 100 is connected to the water outlet of the second fluid passage.

[0075] In the heat exchanger, the low-temperature cooling medium from the cooling supply system passes through the first fluid passage, and the water from the water supply system passes through the second fluid passage. The water in the two fluid passages exchanges heat, and the water temperature is reduced to a supercooled state below the freezing point but not yet crystallized.

[0076] The working process of the entire ice-making system is as follows: first, the second pump in the water supply system delivers water at a temperature close to the freezing point to the second fluid passage of the heat exchanger; at the same time, the first pump in the cooling supply system delivers cooling medium at a temperature below the freezing point to the first fluid passage of the heat exchanger. The two fluids exchange heat in the heat exchanger, and the water temperature is reduced to a supercooled state below the freezing point but not yet crystallized. This supercooled water flows out of the water outlet of the second fluid passage of the heat exchanger and directly enters the inlet 12 of the supercooling relief device 100.

[0077] After entering the supercooling removal device 100, the supercooled water is removed from the supercooling state by impacting the conical filter screen 2, and begins to crystallize to form ice slurry. The conical filter screen 2 concentrates the generated ice slurry to the middle position, which can not only improve the efficiency of removing the supercooling state, but also make the water in the ice slurry converge downward, promoting ice-water separation. The separated water falls from the filter screen 2 to the bottom of the containing cavity 11 and is discharged through the outlet 13. The ice slurry concentrated on the side of the filter screen 2 away from the bottom of the containing cavity is transported to the outside of the shell 1 by the screw rod of the ice discharge assembly 3. The screw rod maintains an appropriate height difference H2 (not less than 100 mm) with the bottom of the filter screen 2, ensuring that the collected ice slurry has a low water content. The front end of the screw rod exceeds the center of the barrel and can stir the ice layer to prevent the system from being blocked due to the accumulation of ice columns that are too high.

[0078] The discharged water is returned to the second temperature control device of the water supply system through the water outlet pipe 131, and after temperature adjustment, it is again introduced into the system for recycling. This closed loop design not only improves the efficiency of water resource utilization, but also reduces the energy consumption of the system, because the temperature of the returned water is relatively low, and less energy is required to heat it to near the freezing point again.

[0079] The ice making system of the present application realizes the complete process flow from the manufacture of supercooled water to the removal of supercooling state to form ice slurry and then to separate and transport the ice slurry through system integration. Each component works cooperatively to improve the overall ice making efficiency and system stability. Compared with the prior art, the present system has the following significant advantages: high ice making efficiency, supercooled water quickly removes the supercooling state and crystallizes through the conical filter screen 2. Good ice-water separation effect, the special design of the filter screen 2 fully separates the ice slurry and water. Strong system stability, the design of the screw rod prevents the system from being blocked due to ice accumulation. Low energy consumption, water recirculation improves resource utilization efficiency.

[0080] The supercooling removal device 100 and the ice making system of the present application are suitable for various scenes requiring efficient ice making, such as food freezing, medical refrigeration, industrial refrigeration and other fields, and have broad application prospects.

[0081] In the present embodiment, the cooling supply system provides a cold carrier medium input heat exchanger below the freezing point of water (0℃) to reduce the temperature of the water to prepare supercooled water. The water supply system provides constant temperature water close to the freezing point temperature to ensure the stability of the water inlet. The cooperation of the cooling supply system and the water supply system ensures that the water flow can quickly and uniformly reach the target temperature range in the heat exchanger.

[0082] It should be understood that although the present specification is described in terms of embodiments, each embodiment does not necessarily contain only one independent technical solution, and the specification is described in this way only for the sake of clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.

[0083] The above detailed description merely illustrates preferred and possible non-limiting implementations of the application, and is not intended to limit the scope of the application. Other equally effective embodiments and modifications will be apparent to those skilled in the art, and are intended to be included within the scope of the application.
