Description

Technical Field

[0001] This utility model relates to the field of glass cooling technology, and in particular to a heat dissipation device for a glass drying oven. Background Technology

[0002] After the glass is dried in the drying oven, it needs to be cooled down. However, if the glass is directly put into the cooling device, it will damage the cooling device and reduce its service life. In addition, the hot air generated when the dried glass enters the cooling device will cause the temperature of the processing workshop to rise, which will have an adverse effect on the surrounding equipment and operators, and may even pose a safety hazard.

[0003] Therefore, it is necessary to develop a rapid preliminary heat dissipation device for glass output after drying in the drying oven, which can achieve preliminary heat dissipation of the glass, so that the temperature of the glass entering the cooling device will not be too high, thereby improving the service life of the cooling device.

Detailed Implementation

[0030] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0031] Example 1

[0032] See Figures 1 to 7 A heat dissipation device for a glass drying oven includes a drying oven 1 and a conveyor 2, the conveyor 2 being driven by a motor 22; it also includes a heat dissipation component 3, the heat dissipation component 3 including a wind box 31 and a cooling component, the wind box 31 being disposed at the lower part of the conveyor 2, the cooling component being disposed in the wind box 31, the wind box 31 also being provided with a fan 33, the fan 33 being powered by an external power source, the top of the wind box 31 being provided with an air outlet 312, and the bottom of the wind box 31 being provided with an air inlet 311.

[0033] like Figures 4 to 7 As shown, the cooling assembly includes a cooling coil 34, a liquid storage tank 35, and a circulation pump 36. The cooling coil 34 is positioned within the air box 31 near the air outlet 312. The liquid storage tank 35 and the circulation pump 36 are located at the top of the air box 31. The input end of the cooling coil 34 is connected to the liquid storage tank 35, and the output end of the cooling coil 34 is connected to the circulation pump 36. The circulation pump 36 and the liquid storage tank 35 are connected via a conduit. The cooling coil 34 is filled with coolant. The cooling coil 34 is made of copper.

[0034] like Figure 4 and Figure 6 As shown, the liquid storage tank 35 is provided with a liquid filling port and a sealing cap 351.

[0035] like Figure 6 and Figure 7 As shown, both the air inlet 311 and the air outlet 312 are equipped with dustproof nets 32, which are bolted to the air box 31.

[0036] like Figure 1 and Figure 2 As shown, the conveyor 2 is equipped with a support 23, and a temperature sensor 24 is mounted on the support 23. The temperature sensor 24 is electrically connected to the controller. The external power supply of the fan 33 and the circulating pump are both electrically connected to the controller. The support 23 and the temperature sensor 24 are arranged in an array.

[0037] like Figure 3 As shown, casters are provided on the rotating shaft 21 of the conveyor 2, and the rubber wheels 211 on two adjacent rotating shafts 21 are staggered.

[0038] like Figure 6 and Figure 7 As shown, the heat dissipation component 3 is provided with a support leg 37 at the bottom, and an anti-slip pad 371 is provided at the end of the support leg 37.

[0039] Working principle

[0040] The core of the heat dissipation device of glass drying oven 1 is to achieve rapid cooling after the glass leaves the drying oven 1 through the synergistic effect of "active air cooling + circulating liquid cooling". At the same time, combined with intelligent temperature control and structural optimization, it ensures heat dissipation efficiency and equipment stability.

[0041] The device connects to a conveyor 2 at the output end of the drying oven 1, and a heat dissipation component 3 is installed at the bottom of the conveyor 2. When the glass is heated by the drying oven 1, its temperature is high. Directly entering the subsequent cooling device would damage the equipment due to the large temperature difference. However, the heat dissipation component 3 can reduce the temperature of the glass to a reasonable range through active cooling, thereby reducing the thermal shock to the conveyor 2 and downstream equipment and extending their service life.

[0042] The air box 31 has an air inlet 311 at the bottom and an air outlet 312 at the top. When the built-in fan 33 is working, outside air is drawn in through the air inlet 311, accelerated by the fan 33, and flows upward, blowing onto the high-temperature glass on the conveyor 2, carrying away some heat, and then discharged from the air outlet 312, forming an air circulation cooling system. In the cooling assembly, the coolant in the liquid storage tank 35 flows through the cooling coil 34, exchanging heat with the air inside the air box 31. When the high-temperature air flows through the cooling coil 34, the heat is absorbed by the coolant, reducing the temperature of the blown-out air and enhancing the cooling effect on the glass. The circulating pump 36 drives the coolant to circulate between the cooling coil 34 and the storage tank 35, continuously removing heat. The storage tank 35 can be connected to an external heat exchange device, which can export the coolant that has absorbed heat through a conduit to cool it down and then return it to the storage tank 35 to maintain the coolant at a low temperature. The storage tank 35 is equipped with a reserved conduit that can be connected to an external heat exchange device to provide a stable and constant coolant. The external heat exchange device is a commercially available heat exchange device.

[0043] Temperature sensors 24, arrayed on the support 23 of conveyor 2, monitor the glass surface temperature in real time and transmit the data to the controller. When the temperature exceeds a set threshold, the controller triggers the fan 33 to start and the circulating pump 36 to run, initiating a heat dissipation mode; when the temperature falls below the set threshold, the controller shuts down the fan 33 and the circulating pump 36 to avoid unnecessary energy consumption and achieve energy-saving operation.

[0044] The dustproof nets 32 of the air inlet 311 and the air outlet 312 prevent dust from entering the air box 31, avoid dust accumulation on the fan blades 33 which affects the speed, and prevent dust from adhering to the surface of the cooling coil 34 and reducing the heat conduction efficiency; the support legs 37 and anti-slip pads 371 at the bottom of the heat dissipation component 3 increase the friction with the ground, reduce the shaking of the equipment during operation, and ensure structural stability.

[0045] The rubber wheels 211 on the conveyor shaft 21 are staggered, which makes the contact points between the bottom of the glass and the rubber wheels 211 more even, reduces the cooling dead zone, and ensures that the heat dissipation of each area of ​​the glass is consistent; the array of temperature sensors 24 can also capture the temperature of different positions of the glass more comprehensively, improving the accuracy of temperature control.

[0046] Detailed operating procedures

[0047] In use, the power to the drying oven 1 and conveyor 2 is turned on. After the glass is heated by the drying oven 1, it is conveyed by the conveyor 2 to the heat dissipation component 3 area. When the glass enters the heat dissipation component 3 area, the array temperature sensor 24 detects its surface temperature.

[0048] If the temperature is greater than or equal to the set high temperature threshold, the controller will automatically start the fan 33 and the circulation pump 36 after receiving the signal: the fan 33 drives the air to enter the air box 31 from the air inlet 311, flow through the cooling coil 34, and the air cooled by the coolant is blown out from the air outlet 312 and blown toward the glass surface to quickly remove the heat.

[0049] If the temperature is below the set low temperature threshold, the controller shuts down the fan 33 and the circulation pump 36, and only slowly dissipates heat through natural convection to save energy.

[0050] After the drying oven 1 stops working and the last piece of glass leaves the heat dissipation component 3, wait 5-10 minutes, turn off the controller power, and then turn off the conveyor 2 and the circulation pump 36 in sequence.

[0051] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not a limitation on the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
