Description

Technical Field

[0001] The present invention relates to the technical field of dynamic ice slurry preparation, and in particular to a supercooled water type dynamic ice slurry system and an ice making method. Background Art

[0002] Supercooling continuous ice making is a new type of ice making method developed in recent years. Compared with the traditional static ice making method, supercooled water continuous ice making has low energy loss and high ice making efficiency, so it has attracted extensive attention from experts and scholars at home and abroad. The principle of supercooled water dynamic ice making is: water is cooled to a supercooled state (below the freezing point but not frozen) in the supercooler. When it flows through the ice slurry generator, the supercooled state of the water is eliminated and becomes an ice-water mixture. Finally, the water and the ice slurry with a higher concentration are separated by a filtering device. Among them, the separated water continues to circulate in the system, and the remaining ice is stored in the ice storage tank.

[0003] At present, water in the heat exchanger is refrigerated by -3℃ ethylene glycol to exchange heat with water, so that the water becomes -2℃. Ethylene glycol is transported through copper exchange tubes. The length of a single copper exchange tube is 100 meters, but the bending section of the copper exchange tube is outside the injection pipe. Due to the temperature of ethylene glycol, this section will cause the moisture in the air to condense into ice crystal structure and adhere to the bending section. Long-term accumulation will form "millennium ice", which will gradually squeeze the copper exchange tube after freezing, accelerating the rust of the pipeline. At the same time, excessive squeezing of the copper exchange tube will cause pipeline blockage, affecting the flow of ethylene glycol. Summary of the invention

DETAILED DESCRIPTION

[0039] Embodiment 1:

[0040] Reference Figure 1-10 and Fig.12As shown, the present invention proposes a supercooled water type dynamic ice slurry system and ice making method, including an injection pipe 1 and a copper exchange tube 2, the copper exchange tube 2 is installed through the injection pipe 1, and the end of the injection pipe 1 is provided with a placement groove for placing the bent section of the copper exchange tube 2, and a sealing box 3 is installed in the placement groove to block the opening of the placement groove, and the sealing box 3 is connected to multiple heating tubes 4, and the heating tube 4 is a standard single-head heating tube: diameter Φ6~Φ25㎜, made of 316l steel. The heating temperature of the sealing box 3 and the heating tube 4 is 1-100℃, and the multiple heating tubes 4 and the multiple copper exchange tubes 2 are arranged at intervals. It should be noted that the sealing box 3 can generate heat after being powered on, and the heating tube 4 and the sealing box 3 are powered on and heated together, and the ice crystal structure formed at the bend of the copper exchange tube 2 can be heated and melted, which can ensure long-term heating treatment. The number of heating tubes 4 is set according to actual conditions, and the heating tubes 4 are inserted around and in the gap of the copper exchange tube 2 as much as possible. In actual use, the sealing box 3 is embedded in the placement groove to prevent accidental scalding of the staff.

[0041] The bottom of the injection pipe 1 is provided with a drain port 7 connected to the placement groove, and the drain port 7 is connected to the sewer. A heat-conducting rod 19 is connected to the side of the sealing box 3 close to the buffer plate 5, and a heating ring 20 is connected to the end of the heat-conducting rod 19 away from the sealing box 3. The heating ring 20 is located just above the drain port 7, and the inner diameter of the heating ring 20 is smaller than the opening diameter of the drain port 7.

[0042] The water formed after the ice crystal structure melts can be discharged into the sewer through the drain port 7, reducing the excessive accumulation and expansion of ice accumulation, which may cause extrusion damage to the copper exchange tube 2. When the ice crystal structure is melted, the heat of the heating ring 20 and the heat-conducting rod 19 can be used to melt the ice crystal structure on the drain port 7, and the ice crystal structure above the drain port 7 is melted into icicles. The formed icicles can fall directly from the drain port 7, which can ensure the unobstructed flow of the drain port 7 and facilitate the discharge of the melted water.

[0043] A side of the heating tube 4 close to the sealing box 3 is connected with a sight glass 6, which is a rod-shaped structure, and the sight glass 6 slides through the sealing box 3. When the ice crystal structure expands and causes displacement by squeezing the buffer plate 5, the sight glass 6 will be pushed to pass through a certain length (5-9MM) in the sealing box 3 at the same time, and the staff can judge the internal icing situation according to the length of the sight glass 6 extending. In use, a push switch can be installed at the end 8mm away from the initial position of the sight glass 6. When the sight glass 6 extends a suitable length, it will touch the push switch, and the push switch is closed to connect the circuit of the sound and light alarm. The sound and light alarm is installed on the top of the equipment housing. The sound and light alarm works to remind the staff, and the staff connects the circuit of the sealing box 3 and the heating tube 4, so that the two heat up and melt the ice crystal structure. After the ice crystal structure is processed, the buffer silicone pad 10 can be reset by the compressed air inside the buffer silicone pad 10, and the buffer silicone pad 10 pushes the buffer plate 5 to reset, and the buffer plate 5 drives the viewing cup 6 to reset.

[0044] The side of the sealing box 3 facing the outside and the sight glass 6 are coated with fluorocarbon paint. The fluorocarbon paint can prevent the ice crystal structure from condensing on the outer surfaces of the sight glass 6 and the sealing box 3, and prevent the condensed ice crystal structure from hindering the extension of the sight glass 6; a ventilation pipe 29 is installed through the sealing box 3, and the ventilation pipe 29 penetrates the buffer silicone pad 10 and the buffer plate 5. A windshield 30 parallel to the buffer plate 5 is also installed on the inner walls of both sides of the placement groove. The gap between the windshield 30 and the buffer plate 5 is 13mm, and the upper and lower sides of the windshield 30 do not contact the upper and lower inner walls of the placement groove. An air inlet hole is penetrated on the windshield 30, and the position of the air inlet hole does not correspond to the position of the air outlet end of the ventilation pipe 29. In actual operation of the equipment, since the temperature of the ethylene glycol transported by the copper exchange tube 2 is -3°C, the temperature of the copper exchange tube 2 is also -3°C. The copper exchange tube 2 then cools the air in the placement tank. Due to the heat conduction of the air, the temperatures of the wind shield 30, the buffer plate 5, etc. are all at -3°C or infinitely close to -3°C.

[0045] When the outside air enters through the air inlet pipe 20 during normal operation, the air at normal temperature of the outside is directly blown onto the wind shield 30 through the air inlet pipe 29. The wind shield 30 blocks the incoming air, and the air spreads around along the surface of the wind shield 30. Since the temperature of the wind shield 30 is also around -3°C, the outside air first contacts the wind shield 30, and then rebounds against the wind shield 30 and contacts the surface of the buffer plate 5. At the same time, part of the outside air is discharged through the air inlet hole and contacts the outer wall of the copper exchange tube 2. The water vapor in the outside air condenses into water droplets on the surface of the wind shield 30 and then forms an ice crystal structure. The preferred position for ice formation is the outer wall of one side of the wind shield 30 close to the buffer plate 5 and the side of the buffer plate 5 close to the wind shield 30. The gap between the buffer plate 5 and the sealing box 3 is filled with the buffer silicone pad 10, which can play a certain sealing effect and prevent the entry of water vapor in the air. The scattered air then enters the placement slot through the air inlet hole and contacts the copper exchange tube 2 , and the remaining water vapor in the air will partially condense into ice crystal structure on the outer wall of the copper exchange tube 2, which can reduce the contact between the external water vapor and the outer wall of the copper exchange tube 2, and reduce the amount of ice on the outer wall of the copper exchange tube 2, thereby reducing the accumulation of ice crystal structure and the squeezing effect on the outer wall of the copper exchange tube 2; when the space between the wind shield 30 and the buffer plate 5 is gradually filled with the ice crystal structure, the volume of the ice crystal structure will continue to increase. Due to the expansion of the volume of the ice crystal structure, the ice crystal structure will squeeze the inner wall of the placement groove, the wind shield 30, and the buffer plate 5. However, there is an air inlet hole on the wind shield 30 as an expansion position for the ice crystal structure to collide, and the buffer plate 5 slides on the heating tube 4. The expansion of the volume of the ice crystal structure will cause compression on the buffer plate 5, causing the buffer plate 5 to move in the placement groove, and the buffer plate 5 pushes the sight glass 6 to extend. The staff can judge whether it is necessary to process the ice crystal structure in the placement groove based on the length of the extended sight glass 6. The maximum extension length of the sight glass 6 is 10 mm. When the sight glass 6 is extended by 8 mm, the space in the placement slot where the copper exchange tube 2 is located is not filled with the ice crystal structure. In this way, the pressure exerted by the ice crystal structure on the outer wall of the copper exchange tube 2 is relatively small, which is not enough to collapse the copper exchange tube 2 and cause a depression.

[0046] The staff can connect the circuit of the sealing box 3 and the heating tube 4 so that both of them start to heat up. When the heating tube 4 heats the ice crystal structure, a hole will be generated on the inner wall of the ice crystal structure. At the same time, multiple heating tubes 4 will create multiple holes in the ice crystal structure, similar to honeycomb coal. As the heating tube 4 heats the ice, it melts and turns it into water. At the same time, the water is heated to generate water vapor. The water vapor quickly expands in the holes on the ice, expanding the entire ice crystal structure, causing the entire ice crystal structure to break into small pieces of crushed ice. As the heating tube 4 continues to heat, the ice crystal structure that has been broken into small pieces can fall directly. The high-temperature water vapor generated by the heating of the heating tube 4 will enter along the cracks in the ice crystal structure, increasing the heat dissipation area of ​​the ice crystal structure, which can increase the efficiency of melting the ice crystal structure. The melted water can flow through the air inlet or the gap between the wind shield 30 and the upper and lower inner walls of the placement slot to the placement slot space where the copper exchange tube 2 is located, and then be discharged through the drain port 7.

[0047] An elastic compression structure is arranged on the periphery of the heating tube 4; the elastic compression structure comprises a telescopic block 8 and a No. 1 spring 9; an active groove which slides with the telescopic block 8 is opened on the periphery of the heating tube 4, and the active groove is connected with the inside of the heating tube 4, and the No. 1 spring 9 is installed in the heating tube 4, and the No. 1 spring 9 makes the telescopic block 8 have a tendency to move out of the active groove.

[0048] When the equipment fails (for example, there is a leak between the injection pipe 1 and the copper exchange tube 2, or in an environment with high humidity), there are many ice crystal structures in the placement tank where the copper exchange tube 2 is located, and ice accumulates at the bend of the copper exchange tube 2. The ice crystal structure first condenses into ice from the outside of the copper exchange tube 2. As time goes by, the outer wall of the ice crystal structure comes into contact with the moisture in the outside air, so that the water vapor on the outer wall of the ice crystal structure condenses into an ice crystal structure. At this time, the pressure of the ice crystal structure on the copper exchange tube 2 is relatively small, and the ice crystal structure can expand the volume of the ice crystal structure from the outer wall of the ice crystal structure. When the entire placement tank is completely frozen, the ice crystal structure continues to expand and needs to squeeze the inner wall of the placement tank and the copper exchange tube 2. Since the ice crystal structure is a whole at this time, the extrusion force caused by the outward expansion of any point therein is generated by the mutual extrusion of the water molecules in the ice crystal structure. Therefore, the pressure exerted by the ice crystal structure on the copper exchange tube 2 and the inner wall of the placement tank is the same. However, the strength of the copper exchange tube 2 is lower than the inner wall of the placement groove, and the ice crystal structure will squeeze the copper exchange tube 2 and cause a depression. Since the heating tube 4 is also in the placement groove, the temperature of the heating tube 4 is the same as or infinitely close to the temperature of the copper exchange tube 2. The surface of the heating tube 4 will also condense the ice crystal structure and squeeze the heating tube 4. At the same time, the telescopic block 8 is compressed into the heating tube 4 by the ice crystal structure. After the telescopic block 8 is compressed, the volume of the ice cavity increases, thereby increasing the space for ice storage.

[0049] Since the force causing the telescopic block 8 to retract into the heating tube 8 is much smaller than the force causing the copper exchange tube 2 and the heating tube 4 to sag (the reaction force of the telescopic block 8 on ice can be ignored here), the increased ice storage space reduces the pressure of the ice crystal structure on the heating tube 4 and the copper exchange tube 2, which can protect the heating tube 4 and the copper exchange tube 2. The squeezing effect of the ice crystal structure will first cause the telescopic block 8 to retract into the heating tube 4. In actual use, a silicone rubber sealing pad is provided between the telescopic block 8 and the heating tube 4 to prevent external water vapor from entering the heating tube 4 and causing ice to form in the heating tube 4, which can play a role of insurance and prevent the staff from not checking the extension of the sight glass 6 in time, and the copper exchange tube 2 is squeezed by the ice crystal structure in the placement slot space where the copper exchange tube 2 is located, thereby preventing the copper exchange tube 2 from being dented.

[0050] When the ice crystal structure reaches 8 mm, the heating tube 4 and the sealing box 3 can be powered on to generate heat to melt the ice crystal structure into water, thereby preventing the ice crystal structure from being squeezed and damaged by long-term accumulation.

[0051] A buffer plate 5 is provided on the side of the sealing box 3 close to the heating tube 4, and the buffer plate 5 is in transitional fit with the placement groove. A buffer structure is provided between the sealing box 3 and the buffer plate 5, and the buffer structure includes a silicone buffer pad 10; the silicone buffer pad 10 is placed between the sealing box 3 and the buffer plate 5, and the heating tube 4 passes through the silicone buffer pad 10 and is connected to the sealing box 3. In a specific embodiment, the silicone buffer pad 10 is a hollow structure. A plurality of openings are provided on the side of the buffer plate 5, and a metal spring 12 is installed at one end of the opening away from the silicone buffer pad 10, and the metal spring 12 is used to block the port of the opening. A plurality of grooves 11 are provided on the side of the sealing box 3 close to the silicone buffer pad 10.

[0052] The material of the silicone buffer pad 10 is relatively soft. When the ice crystal structure expands, it will first act on the buffer plate 5, pushing the buffer plate 5 to slide on the heating tube 4 and squeezing the silicone buffer pad 10. Since the silicone buffer pad 10 is a hollow structure, the air inside it is a dry gas and can have a certain compression space, which can reduce the squeezing of the copper exchange tube 2 by the ice crystal structure. When the buffer plate 5 squeezes the silicone buffer pad 10, the air inside the silicone buffer pad 10 can expand the part of the back into the groove 11 after compression, and can also be opened, so that the gap between the buffer plate 5 and the sealing box 3 is smaller, so as to facilitate more compression. When the ice crystal structure continues to expand, it will squeeze the metal spring 12. Since the deformation force of the metal spring 12 is small, the metal spring 12 will change from a protruding state toward the opening to a sunken state toward the opening, such as Figure 6 , Figure 7As shown. In actual use, the buffer plate 5 can be a heat-conducting metal plate, which can transfer the heat from the heating tube 4 to a certain extent to melt the ice crystal structure. The buffer plate 5 and the inner wall of the placement groove are coated with lubricating oil. The silicone cushion pad 10 is partially bonded to the buffer plate 5 and the sealing box 3, and the rest of the parts are coated with lubricating oil to achieve a sealing effect. It can prevent the water vapor in the gap between the three from freezing into ice and gradually expanding, causing the buffer plate 5 to be unable to slide. The role of the metal shrapnel 12 is similar to that of the telescopic block 8. The metal shrapnel 12 has two states, the state is as Figure 6 As shown, the metal spring 12 protrudes outward from the opening; State 2 is as shown Figure 7 As shown, the metal spring 12 is concave toward the opening, and the metal spring 12 is in a normal state. Figure 6 At the same time, the silicone cushion pad 10 can block the position of the placement groove opening, and at the same time, the ice crystal structure compresses the buffer plate 5 and pushes the buffer plate 5 to move and compress the silicone cushion pad 10, so that the silicone cushion pad 10 is compressed and opened, making the gap between the silicone cushion pad 10 and the inner wall of the placement groove smaller, which can reduce the outside air from entering the placement groove through the gap between the sealing box 3 and the inner wall of the placement groove, and improve the sealing performance.

[0053] Embodiment 2:

[0054] like Figure 1-11 As shown, what is different from the first embodiment is that the sealing box 3 is a hollow structure, one end of the heating tube 4 is inserted into the sealing box 3 and communicated with the inside of the sealing box 3, the end of the heating tube 4 away from the sealing box 3 is sealed, the sealing box 3 is connected with an air inlet pipe 13, the air inlet pipe 13 is connected with a fan and an air dryer, an air outlet hole 21 communicating with the inside of the sealing box 3 is opened through the telescopic block 8, and a sealing structure capable of sealing the metal spring 12 is installed on the telescopic block 8. The sealing device includes a conical sealing block 14, a mounting frame 15 and a No. 2 spring 16; a conical groove 17 connected to the air outlet is opened in the telescopic block 8; the conical groove 17 is coaxially arranged with the air outlet, the conical sealing block 14 is slidably arranged in the conical groove 17, and the conical sealing block 14 can block the conical groove 17, the mounting frame 15 is connected to the inner wall of the conical groove 17, and a telescopic rod 18 is connected to the side of the conical sealing block 14 close to the mounting frame 15, the telescopic rod 18 slides through the mounting frame 15, the No. 2 spring 16 is mounted on the telescopic rod 18, and the two ends of the telescopic rod 18 are respectively against the conical sealing block 14 and the mounting frame 15.

[0055] It should be noted that the air dryer is an air filter composed of an air filter element that can absorb water, and its main materials are activated carbon, air desiccant and other materials to filter the air. It can prevent the outside air from entering the heating tube 4, and prevent the heating tube 4 from freezing when not in use. When melting the ice crystal structure, the sealing box 3 and the heating tube 4 can be powered on to generate heat to melt the ice crystal structure. After the ice crystal structure is melted into water, the fan is operated to blow the external air into the sealing box 3 and the heating tube 4. The air pressure in the heating tube 4 pushes the sealing block 14 in the conical groove 17, so that there is a gap between the inner wall of the sealing block 14 and the conical groove 17. The air heated in the heating tube 4 is discharged through the air outlet 21 and blown to the outer wall of the copper exchange tube 2, which can dry the water stains remaining on the outer wall of the copper exchange tube 2, and avoid the water stains remaining and causing the outer wall of the copper exchange tube 2 to freeze again quickly. When there is no air blowing, the second spring 16 pushes the conical sealing block 14 to return to its original position, so that the conical sealing block 14 blocks the conical groove 17 to prevent moisture in the groove from entering the heating tube 4.

[0056] In actual use, before the copper exchange tube 2 is frozen, the sealing box 3 and the heating tube 4 can be powered on to heat up, and the heating temperature is 1-3°C. The fan can then draw the outside wind into the sealing box 3 and the heating tube 4, and the air pressure of the heating tube 4 pushes the conical sealing block 14 to slide in the conical groove 17, and the conical sealing block 14 pushes the telescopic rod 18 to slide on the mounting frame 15. The flowing air brings the hot air in the heating tube 4 out and blows it into the placement groove and the outer wall of the heating tube 4, which can heat the temperature in the placement groove and reduce the possibility of ice on the outer wall of the copper exchange tube 2.

[0057] In actual use, when ice reaches a certain thickness at the bend of the copper exchange tube 2, the sealing box 3 and the heating tube 4 can be powered on regularly to heat up. For example, in air conditioning ice making and cold storage, the ice making work of large factories is usually 8 hours at night, which can effectively avoid the peak period of electricity consumption. The heating time of the sealing box 3 and the heating tube 4 can be controlled from 11 am to 6 pm during the day, and the heating temperature is also controlled at 1-2°C. The heated heating tube 4 and the sealing box 3 can dissolve part of the ice crystal structure, and a small amount of ice crystal structure remains on the outer wall of the bend section of the copper exchange tube 2. When ethylene glycol is transported through the copper exchange tube 2, the energy loss can be reduced, and the ice crystal structure can be avoided from squeezing the copper exchange tube 2 and causing the copper exchange tube 2 to be concave and damaged, thereby ensuring the flow of ethylene glycol.
