The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0037] The following will describe the heat source application system for a coating factory according to an embodiment of the present application with reference to the drawings.

[0038] Please refer to Figure 1 , Figure 1 , which shows a schematic structural diagram of the heat source application system for a coating factory of the present application, including an air conditioner 1 and a drying oven in the coating workshop. The air conditioner 1 is used to adjust the temperature of each workshop in the coating factory, and the drying oven in the coating workshop is used to dry the coated coating substrate.

[0039] Specifically, the air conditioner 1 includes a condenser 11, and a heat collector 2 is provided on the condenser 11. The water outlet end of the heat collector 2 is connected to a high-temperature water outlet pipe 3, and the water inlet end of the heat collector 2 is connected to a low-temperature return water pipe 4. The drying oven in the coating workshop includes a chassis 5, a water-cooled radiator 6 and a substrate positioning structure 7 arranged in the chassis 5. The water inlet end of the water-cooled radiator 6 is connected to the high-temperature water outlet pipe, the water outlet end of the water-cooled radiator 6 is connected to the low-temperature return water pipe 4, and the substrate positioning structure 7 is used to place the coated coating substrate and is arranged above the water-cooled radiator 6.

[0040] It can be understood that the condenser 11 of the air conditioner 1 is a heat exchange device, and its core function is to convert gas or vapor into liquid, and this process is accompanied by the release of heat. Therefore, the temperature of the condenser 11 will be relatively high during operation. The heat collector 2 includes a heat absorption plate (coated with a heat absorption coating), and the heat absorption plate absorbs the heat of the condenser 11 and converts it into heat energy, and then transfers it to the water flowing behind it. After the water is heated, it is transported to the place where heat energy is required (the drying oven in the coating workshop).

[0041] In this embodiment, when the heat source application system for the coating factory is in operation, the air conditioner 1 adjusts the temperature of each workshop and releases heat along with the condenser 11. The heat released by the condenser 11 is exchanged through the provided collector 2, and the heat is exchanged to the water in the high-temperature outlet pipe 3. The water temperature in the high-temperature outlet pipe 3 rises, and the high-temperature water in the high-temperature outlet pipe 3 passes through the water radiator 6 and returns to the collector 2 through the low-temperature return pipe 4, realizing water circulation.

[0042] When the high-temperature water passes through the water radiator 6, the water radiator 6 exchanges the heat of the high-temperature water to the drying box in the coating workshop again, increasing the temperature in the drying box in the coating workshop, thereby improving the drying efficiency of the coating liner on the liner positioning structure 7.

[0043] Through the provided collector 2, high-temperature outlet pipe 3, low-temperature return pipe 4 and water radiator 6, the heat source of the condenser 11 on the air conditioner 1 is recovered by the collector 2 and reused at the place where the factory heat source is required (coating workshop), improving the drying efficiency of the coating liner and the energy reuse rate, and contributing to clean production and environmental protection.

[0044] Among them, in the traditional technology, the processed coating liner is air-dried, and the drying efficiency is low. The heat source application system for the coating factory can collect and convert the heat discharged by the air conditioner 1, transfer the heat source from the air conditioner 1 to the chassis 5 through the water radiator 6, and accelerate the drying rate of the coating liner by increasing the temperature.

[0045] Furthermore, the high-temperature outlet pipe 3 is used to transport the high-temperature water at the collector 2 to the water radiator 6. To reduce the heat loss of the high-temperature water during transmission, a heat insulation layer is sleeved outside the high-temperature outlet pipe 3. The heat insulation layer includes but is not limited to rock wool, glass wool, polystyrene foam, and extruded polystyrene foam.

[0046] Furthermore, the coated liner after coating is placed on the liner positioning structure 7 for drying. Since the water radiator 6 will heat the surrounding air and hot air has the property of flowing upward, setting the water radiator 6 below the liner positioning structure 7 can ensure that the hot air flows through the coated liner during the upward movement, fully drying the coated liner.

[0047] In some embodiments, refer to Figures 1-3 , the liner positioning structure 7 includes a bottom plate 71 and a plurality of support plates 72. The bottom plate 71 is arranged above the water radiator 6, and the plurality of support plates 72 are arranged at intervals on the bottom plate 71 and form a plurality of support slots for placing the coated liner.

[0048] Further, the bottom plate 71 is horizontally connected inside the chassis 5, and the support plates 72 are spaced and connected to the bottom plate 71. When the coating liner is placed on the liner positioning structure 7, the circumferential edge of the coating liner abuts against the bottom plate 71, and the side surface of the coating liner abuts against the support plates 72. Hot air flows through the gap between the support plates 72 of the coating liner, thereby realizing the drying of the coating liner.

[0049] Among them, the bottom plate 71 can be connected to the chassis 5 by screws, and the support plates 72 can be connected to the bottom plate 71 by screws.

[0050] Further, a plurality of support plates 72 are arranged in parallel with each other, each support plate 72 is perpendicular to the bottom plate 71, and ventilation holes 73 are provided on the bottom plate 71 opposite to the water-cooled radiator 6.

[0051] To improve the efficiency of the hot air flowing between the support plates 72, the plurality of support plates 72 are arranged in parallel. In this way, when the hot air flows between the support plates 72, it will not be blocked by the support plates 72, the flow is smoother, and the speed of the hot air flow will not be affected, thereby improving the drying effect.

[0052] The provided ventilation holes 73 are used to ensure that the hot air of the water-cooled radiator 6 can smoothly enter between the support plates 72, and prevent the hot air from being blocked under the bottom plate 71.

[0053] Further, a plurality of ventilation holes 73 are provided and evenly distributed on the bottom plate 71. The area ratio of the ventilation holes 73 on the bottom plate 71 is not less than 80%, so as to improve the passing rate of the hot air on the bottom plate 71.

[0054] In some embodiments, refer to Figure 1 and Figure 3 , the heat source application system for the coating factory further includes a circulation pump 8 for driving the liquid to flow. The circulation pump 8 is connected to the high-temperature water outlet pipe 3, or the circulation pump 8 is connected to the low-temperature water return pipe 4.

[0055] To better realize the circulating flow of the water in the circulating pipeline composed of the high-temperature water outlet pipe 3, the water-cooled radiator 6, the low-temperature water return pipe 4 and the collector 2, a circulation pump 8 is provided on the circulating pipeline. After the circulation pump 8 is turned on, it applies pressure to the water flow, accelerates the circulating flow of the water in the circulating pipeline, and ensures that the high-temperature water in the collector 2 can quickly reach the water-cooled radiator 6, reducing heat loss.

[0056] Since the high-temperature water outlet pipe 3, the water-cooled radiator 6, the low-temperature water return pipe 4 and the collector 2 form a circulating pipeline, therefore, for the convenience of installation, the circulation pump 8 can be selected to be installed on any one of the high-temperature water outlet pipe 3 or the low-temperature water return pipe 4.

[0057] Of course, the circulation pump 8 can also be arranged at the water blowing port or the water inlet of the collector 2, or the circulation pump 8 can be arranged at the water inlet or the water outlet of the water-cooled radiator 6.

[0058] In some embodiments, referring to Figure 1 and Figure 3 , the heat source application system for the coating factory further includes a water replenishing tank 9 for replenishing water to the pipeline. The water replenishing tank 9 is connected to the high-temperature water outlet pipeline 3, or the water replenishing tank 9 is connected to the low-temperature water return pipeline 4.

[0059] The water replenishing tank 9 is used to replenish water to the circulation pipeline formed by the high-temperature water outlet pipeline 3, the water-cooled radiator 6, the low-temperature water return pipeline 4 and the collector 2, ensuring that there is sufficient water in the circulation pipeline for heat exchange and flow, and ensuring the normal operation of the circulation pipeline.

[0060] In some embodiments, referring to Figure 1 and Figure 3 , an air drying fan 10 is further provided in the chassis 5. The air drying fan 10 is arranged below the water-cooled radiator 6, and the air outlet of the air drying fan 10 is directly opposite to the lining plate positioning structure 7.

[0061] It can be understood that when drying the coating lining plate, the drying efficiency is related not only to the air temperature but also to the air flow velocity. The faster the air flow velocity, the higher the drying efficiency.

[0062] After the air drying fan 10 is set, the air drying fan 10 can accelerate the flow of hot air near the water-cooled radiator 6, forming a directional flow of hot air from the air drying fan 10 to the lining plate positioning structure 7. This greatly accelerates the air flow velocity around the coating lining plate, can fully blow the hot air carrying the exchanged heat to the periphery of the coating lining plate, thereby accelerating the drying efficiency and improving the heat utilization rate.

[0063] In some embodiments, the ventilation holes 73 are set as spiral holes. When the air drying fan 10 is started, the formed air flow can form a certain gas eddy when passing through the spiral ventilation holes 73, changing the velocity and direction of the air flow, so that the air flow can more fully contact the surface of the coating lining plate, achieving the effect of improving the drying efficiency and improving the utilization efficiency of heat.

[0064] Furthermore, support ribs (not shown in the figure) are provided on the side wall of the support plate 72. The extending direction of the support ribs is perpendicular to the bottom plate 71. When the coating lining plate is placed between adjacent support plates 72, the support ribs are used to abut against the coating lining plate, so that only a small part of the area of the coating lining plate contacts the support ribs on the support plate 72, and the rest are in a suspended state, enabling the air flow to flow around the coating lining plate more without dead angles and improving the drying efficiency.

[0065] Furthermore, the supporting rib is a hollow structure with a plurality of hollow holes, which further reduces the contact area between the support plate 72 and the coating lining plate, reduces the dead area of drying of the coating lining plate, improves the drying efficiency, and at the same time makes the drying more uniform.

[0066] Furthermore, referring to Figure 1 and Figure 3 , to improve the air flow efficiency, the chassis 5 is provided with an air inlet 51 and an air outlet 52. The air inlet 51 is located below the water-cooled radiator 6, and the air outlet 52 is located above the lining plate positioning structure 7.

[0067] After setting the air inlet 51 and the air outlet 52, the original air internal circulation is converted into air external circulation, that is, the external air enters the chassis 5 from the air inlet 51 and then is discharged from the air outlet 52. When the air is discharged from the air outlet 52, it can also carry the water vapor in the air, ensuring that the internal environment of the chassis 5 is drier, and improving the drying efficiency and heat utilization rate.

[0068] Furthermore, the water-cooled radiator 6 includes a serpentine tube, and the two ends of the serpentine tube are respectively connected to the high-temperature water outlet pipe 3 and the low-temperature water return pipe 4.

[0069] The serpentine tube refers to a tubular structure designed to be continuously bent or spiral. The high-temperature water flowing in from the high-temperature water outlet pipe 3 flows through the serpentine tube and then into the low-temperature water return pipe 4. The serpentine tube structure can significantly increase the contact area between the high-temperature water in the water-cooled radiator 6 and the external environment, thereby improving the heat exchange efficiency and heat utilization rate.

[0070] In some embodiments, referring to Figure 3 , the heat source application system for the coating factory further includes an ultrasonic cleaning machine 101. The ultrasonic cleaning machine 101 includes a heating device. The water inlet of the heating device is connected to the high-temperature water outlet pipe 3 through a high-temperature water outlet branch pipe 102, and the water outlet of the heating device is connected to the low-temperature water return pipe 4 through a low-temperature water return branch pipe 103.

[0071] It can be understood that in addition to coating, the coating workshop also needs to clean the equipment before and after coating, so there is also a cleaning workshop for cleaning operations. When cleaning parts with the ultrasonic cleaning machine 101, ultrapure water is required. In some cases, the ultrapure water needs to be heated to effectively clean the parts. For example, when there is cured glue on the parts, a higher temperature environment is required to clean the cured glue. Therefore, the ultrasonic cleaning machine 101 also requires a heat source.

[0072] In this embodiment, the heat discharged by the air conditioner 1 is not only used for the drying step, but also can be used to heat the ultrasonic cleaner 101 to adjust the temperature of ultrapure water. Specifically, the high-temperature water in the high-temperature water outlet branch pipe 102 passes through a heating device, and the heating device exchanges heat with the ultrapure water to increase the temperature of the ultrapure water, and then flows into the low-temperature return branch pipe and flows back to the collector 2 again for heat exchange. Thereby, the utilization rate of heat is further improved, achieving the effect of energy conservation and emission reduction.

[0073] Furthermore, referring to Figure 3 , a water outlet control valve 104 is provided on the high-temperature water outlet branch pipe 102, and the water outlet control valve 104 is used to conduct or block the high-temperature water outlet branch pipe 102. A return water control valve 105 is provided on the low-temperature return water branch pipe 103, and the return water control valve 105 is used to conduct or block the low-temperature return water branch pipe 103.

[0074] The on-off of the high-temperature water outlet branch pipe 102 and the low-temperature return water branch pipe 103 can be controlled by the water outlet control valve 104 and the return water control valve 105, thereby controlling whether to heat the ultrasonic cleaner 101.

[0075] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
