Description

Technical Field

[0001] This invention relates to a cooling structure device, and more particularly to a cooling structure for surface treatment of galvanized steel sheets and its application method, belonging to the field of galvanized steel sheet processing. Background Technology

[0002] Galvanized steel sheet is produced by immersing thin steel sheets in a molten zinc bath, causing a layer of zinc to adhere to its surface. It is primarily produced using a continuous galvanizing process, where coiled steel sheets are continuously immersed in a zinc bath to create galvanized steel sheets. Alloyed galvanized steel sheets are also manufactured using a hot-dip method, but after exiting the bath, they are immediately heated to approximately 500°C to form an alloy coating of zinc and iron. This type of galvanized sheet exhibits excellent paint adhesion and weldability. Because of its high surface temperature, freshly galvanized steel sheets are not suitable for immediate storage and require cooling treatment first.

[0003] According to Chinese patent document CN218539795U, a cooling water tank for galvanized sheet production is disclosed. This tank disperses and blows air through the high-temperature water, enabling rapid heat dissipation and circulation, thereby improving cooling water efficiency and reliability. The tank includes a galvanized sheet cooling water tank, a drain pipe, a drain pump, a dispersion spray head, a circulating water tank, a guide ladder, a blower head, a fan frame, a fan motor, fan blades, an inlet pump, an inlet pipe, a spray head bracket, and a blower bracket. The output end of the galvanized sheet cooling water tank is connected to a drain pipe, on which a drain pump is installed. The output end of the drain pipe is connected to the input end of the dispersion spray head. The top left side of the circulating water tank is connected to the middle of the bottom end of the guide ladder. The top left middle of the guide ladder is connected to the middle of the bottom end of the dispersion spray head via the spray head bracket. The output end of the circulating water tank is connected to the input end of the inlet pipe, and the output end of the inlet pipe is connected to the input end of the galvanized sheet cooling water tank. An inlet pump is installed on the inlet pipe.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, when the aforementioned equipment is used, during operation and production, the galvanized sheet is cooled in a galvanized sheet cooling water tank. When the water temperature inside the galvanized sheet cooling water tank is too high and requires cooling, a drain pump operates, drawing water from the galvanized sheet cooling water tank through a drain pipe and distributing it through a dispersed spray nozzle to the top of a guide ladder. The water then slides evenly down the guide ladder into a circulating water tank. During this process, a fan motor operates, causing the fan blades to rotate and the airflow diffused by the blower head to cool the water evenly discharged from the guide ladder. Water in the circulating water tank can also be drawn into the galvanized sheet cooling water tank through an inlet pump via an inlet pipe. Although this device uses a fan to dissipate the heated water... It's hot, but with the continuous heating of the water in the cooling tank by the galvanized sheets on the production line, when the water needs to be cooled to a suitable temperature, the fan accelerates the airflow from the surrounding area. However, due to the influence of the surrounding air temperature, the resulting airflow does not achieve the expected cooling effect, and the water in the cooling tank continues to rise. The overheated cooling water is less effective at cooling the galvanized sheets than the cooler water, and the overheated water can scald workers on the production line. To get cooler water again, the only options are to replace the water in the cooling tank or wait for a period of time, which wastes more time and affects production efficiency. The time limit for the cooling water in the cooling tank to be used is greatly shortened when the heat dissipation is insufficient.

[0005] Therefore, it is urgent to improve the cooling structure of galvanized sheet surface treatment to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling structure and its usage method for galvanized sheet surface treatment. This structure involves pressurizing refrigerant and then discharging it through heat dissipation pipes. In these pipes, the gaseous refrigerant is converted into a liquid state. As the liquid refrigerant flows through the pipes, it absorbs heat from the surrounding environment, lowering the temperature of the surrounding air and the water tank, thus achieving a cooling effect. Multiple fans, connected by L-shaped ventilation pipes, air guide pipes, and circular air guide pipes, transport cold air from the cooling chamber to the water tank, acting on the water flow. This cooling method is unaffected by the surrounding environment, transforming the fan power source into the cold air generated by the refrigerant. Driven by multiple fans, the air in the water tank circulates, converting the hot air brought by the water flow into cold air, further enhancing the fan cooling effect and more efficiently reducing the temperature of the water in the cooling water tank.

[0007] To achieve the above objectives, the main technical solution adopted by the present invention includes: a cooling structure for galvanized sheet surface treatment, comprising a water channel box and a cooling water tank, an equipment box fixedly disposed below the water channel box, a compressor disposed on the bottom wall of the equipment box, a heat dissipation pipe connected to the output end of the compressor, a refrigeration pipe embedded in the lower end face of the water channel box, the input end of the refrigeration pipe connected to the end of the heat dissipation pipe away from the compressor, the output end of the refrigeration pipe connected to the input end of the compressor, multiple fans disposed on both sides of the water channel box, each fan being fitted with a sealed box, air guide pipes disposed on both sides of the water channel box, a circular air guide pipe connected between the multiple sealed boxes and the air guide pipes, a refrigeration box fixedly disposed below the water channel box, the refrigeration box being fitted outside the refrigeration pipe, and an L-shaped vent pipe connected between the air guide pipes and the refrigeration box.

[0008] Preferably, a heat dissipation groove is provided on one side of the equipment box. The heat dissipation groove is not connected to the inside of the equipment box. The heat dissipation groove is sleeved on the outside of the heat dissipation pipe and its opening faces the outside of the equipment box. Multiple heat dissipation fins are sleeved on the heat dissipation pipe, and a cooling fan is fixedly provided at the opening of the heat dissipation groove.

[0009] Preferably, the bottom wall of the water channel box is provided with multiple baffles, and the multiple baffles are arranged alternately.

[0010] Preferably, the upper wall of the water channel box is connected to multiple ventilation openings, each of the multiple ventilation openings is slidably connected to a partition, and each of the multiple partitions is provided with a handle on one side.

[0011] Preferably, a No. 1 water guide pipe is connected between the water inlet end of the water channel box and the water outlet end of the cooling water box, and a No. 1 water pump is provided at the bottom of one side wall of the cooling water box, and the No. 1 water pump is connected to the No. 1 water guide pipe.

[0012] Preferably, a second water guide pipe is connected between the water outlet of the water channel box and the water inlet of the cooling water box, and a second water pump is provided on the other side wall of the cooling water box, and the second water pump is connected to the second water guide pipe.

[0013] Preferably, a filter box is fitted in the center of the second water guide pipe, and multiple filter plates are movably connected to the filter box.

[0014] Preferably, the bottom wall of the refrigeration box is connected to an air intake fan, and the air intake end of the air intake fan is provided with a filter screen.

[0015] Preferably, the compressor model is Copeland ZR61KC-TFD-522.

[0016] A method for using a cooling structure for surface treatment of galvanized steel sheet includes the following steps:

[0017] S1: First, the No. 1 water pipe guides the water in the cooling water tank into the water inlet box, and the water flows in the water inlet box under the action of multiple baffles slowing down the water flow.

[0018] S2: Then, the compressor pressurizes the refrigerant and discharges it through the heat dissipation pipe. In the heat dissipation pipe, the gaseous refrigerant turns into a liquid. As the liquid refrigerant flows in the heat dissipation pipe, it absorbs heat from the surroundings, reducing the temperature of the surrounding air and the water tank, thus achieving a cooling effect.

[0019] S3: Next, multiple fans, through the interconnection of the L-shaped ventilation pipe, air guide pipe, and air guide round pipe, transport the cold air in the refrigeration box to the water channel box and act on the water flow.

[0020] S4: Finally, the cooled water flows into the cooling water tank through the No. 2 air guide pipe after being filtered by the filter box.

[0021] This invention has at least the following beneficial effects:

[0022] 1. During use, the refrigerant is pressurized and discharged through the heat dissipation pipe. In the heat dissipation pipe, the gaseous refrigerant is converted into a liquid state. As the liquid refrigerant flows in the heat dissipation pipe, it absorbs heat from the surrounding environment, reducing the temperature of the surrounding air and the water tank, thus achieving a cooling effect. Multiple fans, connected by L-shaped vent pipes, air guide pipes, and air guide round pipes, transport the cold air in the cooling box to the water tank and act on the water flow. This cooling method is not affected by the surrounding environment. The fan power source is changed to the cold air generated by the refrigerant cooling. Driven by multiple fans, the air in the water tank is circulated, turning the hot air brought by the water flow into cold air, further enhancing the fan cooling effect and more efficiently reducing the temperature of the water in the cooling water tank, achieving the purpose of rapid water cooling.

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] like Figures 1-3 As shown, this embodiment provides a cooling structure for galvanized sheet surface treatment, including a water channel box 1 and a cooling water tank 2. An equipment box 3 is fixedly installed below the water channel box 1. A compressor 4, model Copeland ZR61KC-TFD-522, is installed on the bottom wall of the equipment box 3. The output end of the compressor 4 is connected to a heat dissipation pipe 5. A refrigeration pipe 6 is embedded in the lower end face of the water channel box 1. The refrigeration pipe 6 is bent and positioned below the water channel box 1 to increase its length. To maximize the cooling effect on the water channel box 1 when the refrigerant flows within it, the input end of the refrigeration pipe 6 is connected to the end of the heat dissipation pipe 5 furthest from the compressor 4, and the output end of the refrigeration pipe 6 is connected to the input end of the compressor 4. Multiple fans 7 are installed on both sides of the water channel box 1. The multiple fans 7 effectively circulate the air within the water channel box 1, improving the subsequent delivery of cold air. Each fan 7 is encased in a sealed box 8. Air guide pipes 9 are installed on both sides of the water channel box 1. Each sealed box 8 and the air duct 9 are connected by an air duct round pipe 10. A refrigeration box 11 is fixedly installed below the water channel box 1. An air intake fan 26 is connected to the bottom wall of the refrigeration box 11. A filter screen 27 is installed at the air intake end of the air intake fan 26. The refrigeration box 11 prevents the cold air generated by the refrigeration pipe 6 from escaping into the outside air, which is beneficial to the cooling effect of multiple fans 7. The refrigeration box 11 is fitted on the outside of the refrigeration pipe 6. An L-shaped vent pipe 12 is connected between the air duct 9 and the refrigeration box 11. The connection between the air duct 9, the air duct round pipe 10 and the L-shaped vent pipe 12 can ensure that there is no leakage when multiple fans 7 deliver cold air. A heat dissipation slot 13 is opened on one side of the equipment box 3. The heat dissipation slot 13 is not connected to the inside of the equipment box 3. The heat dissipation slot 13 is fitted on the outside of the heat dissipation pipe 5 and the opening faces the outside of the equipment box 3. Multiple heat dissipation fins 14 are fitted on the heat dissipation pipe 5. A heat dissipation fan 15 is fixedly installed at the opening of the heat dissipation slot 13. The heat dissipation fan 15 and the heat dissipation fins 14 are beneficial to the heat dissipation of the heat dissipation pipe 5.

[0030] During use, the compressor 4 pressurizes the refrigerant and discharges it through the heat dissipation pipe 5. In the heat dissipation pipe 5, the gaseous refrigerant turns into a liquid. As the liquid refrigerant flows in the refrigeration pipe 6, its boiling point decreases after losing high pressure, and it will evaporate and absorb at room temperature. Therefore, the refrigerant in the refrigeration pipe 6 continuously absorbs the surrounding heat while flowing, reducing the temperature of the surrounding air and the water channel box 1, thus achieving a cooling effect. Multiple fans 7, connected by the L-shaped vent pipe 12, the air guide pipe 9, and the air guide round pipe 10, transport the cold air in the refrigeration box 11 to the water channel box 1 and act on the water flow.

[0031] Furthermore, such as Figures 1-3 As shown, multiple baffles 16 are provided on the bottom wall of the water channel box 1, and the multiple baffles 16 are staggered. The staggered arrangement of the multiple baffles 16 helps to block the water flow in the water channel box 1, slowing down the water speed, so that the water flow time in the water channel box 1 is increased, and the water flow is further extended by the cooling air. A first water guide pipe 20 is connected between the water inlet end of the water channel box 1 and the water outlet end of the cooling water tank 2. A first water pump 21 is provided at the bottom of one side wall of the cooling water tank 2, and the first water pump 21 is connected to the first water guide pipe 20. A second water guide pipe 22 is connected between the water outlet end of the water channel box 1 and the water inlet end of the cooling water tank 2. A second water pump 23 is provided on the other side wall of the cooling water tank 2, and the second water pump 23 is connected to the second water guide pipe 22. A filter box 24 is sleeved in the middle of the second air guide pipe, and multiple filter plates 25 are movably connected to the filter box 24. The filter box 24 can filter the water drawn from the first water pipe 20 before it flows into the cooling water tank 2, thereby increasing the water usage time in the cooling water tank 2 and reducing costs and time wasted on water replacement. The upper wall of the water channel box 1 is connected to multiple vents 17, and each vent 17 is slidably connected to a partition 18. Each partition 18 has a handle 19 on one side. When the water in the cooling water tank 2 is not overheated, the partition 18 can be opened to connect the water channel box 1 with the outside through the vents 17, so as to achieve natural heat dissipation. It can also be used for circulating hot and cold air. When multiple fans deliver cold air from the cooling box 11 into the water channel box 1, the internal pressure of the water channel box 1 is relatively high. The ventilation effect of the vents 17 can release this pressure and ensure the stability of the internal pressure of the water channel box 1.

[0032] In use, the No. 1 water pipe 20 guides the water in the cooling water tank 2 into the water channel box 1, and the water flows in the water channel box 1 under the action of multiple baffles 16 to slow down the water flow. Then, the cooled water flows into the cooling water tank 2 through the No. 2 air pipe after being filtered by the filter box 24.

[0033] like Figures 1-3 As shown in this embodiment, the method of using a cooling structure for surface treatment of galvanized steel sheets includes the following steps:

[0034] S1: First, the No. 1 water pipe 20 guides the water in the cooling water tank 2 into the water inlet channel 1, and the water flows in the water channel 1 under the action of multiple baffles 16 to slow down the water flow.

[0035] S2: Then, the compressor 4 pressurizes the refrigerant and discharges it through the heat dissipation pipe 5. In the heat dissipation pipe 5, the gaseous refrigerant is converted into a liquid state. The liquid refrigerant absorbs the surrounding heat while flowing in the refrigeration pipe 6, thereby reducing the temperature of the surrounding air and the water tank 1 and achieving the cooling effect.

[0036] S3: Next, multiple fans 7, through the interconnection of the L-shaped ventilation pipe 12, the air guide pipe 9, and the air guide round pipe 10, transport the cold air in the refrigeration box 11 to the water channel box 1 and act on the water flow.

[0037] S4: Finally, the cooled water flows into the cooling water tank 2 after being filtered by the filter box 24 through the second air guide pipe.
