Technical Field
[0001] This utility model relates to the field of drying oven technology, and in particular to a cooling device suitable for the high-temperature environment at the top of a drying oven. Background Technology
[0002] In the industrial production of glass fiber, glass fiber is wet after being drawn into shape. It needs to be dried to become dry before subsequent packaging and winding processes can proceed normally. During the drying process, using a microwave drying oven can significantly reduce the drying time.
[0003] Microwave drying ovens are typically designed with the microwave control system mounted on top of the oven, which facilitates the drying of glass fibers and improves production efficiency.
[0004] However, in summer, due to the heat dissipation of the oven body and the influence of the environment, the installation environment of the microwave control system will reach 50°C to 60°C. At this time, the effect of drawing air from the top of the drying oven to cool the microwave power supply and magnetron is not good. This causes the microwave control to frequently report over-temperature faults, and the operating power is lower than the power required by the process. This reduces the drying and digestion capacity of the products, and the quality of the dried products does not meet the process requirements, posing a potential quality hazard. Utility Model Content
[0005] The purpose of this invention is to provide a cooling device suitable for high-temperature environments at the top of a drying oven, which facilitates cooling of the drying oven during summer use, improves the operating power of the microwave system, reduces potential quality issues in dried products, and increases drying efficiency.
[0006] To achieve the above objectives, this utility model provides a cooling device suitable for high-temperature environments at the top of a drying oven, including a drying oven top platform, a cooling equipment control cabinet, a mounting plate, an induced draft fan, an air supply assembly, and a mounting assembly.
[0007] The cooling equipment control cabinet is fixedly connected to the top platform of the drying furnace and is located on one side of the top platform of the drying furnace. The mounting plate is fixedly connected to the top platform of the drying furnace and is located on the side of the top platform of the drying furnace closer to the cooling equipment control cabinet. The induced draft fan is fixedly mounted on the mounting plate. The air supply components are respectively mounted on the induced draft fan and the cooling equipment control cabinet. The mounting components are mounted on the top platform of the drying furnace.
[0008] The air supply assembly includes an air supply pipe and a connecting pipe. The air supply pipe is connected to the induced draft fan. One end of the connecting pipe is connected to the air supply pipe, and the other end of the connecting pipe is connected to the cooling equipment control cabinet.
[0009] The air supply assembly further includes a ventilation duct and an air inlet duct. The ventilation duct is connected to the air inlet of the induced draft fan. The air inlet duct is fixedly connected to the ventilation duct and is located on one side of the ventilation duct.
[0010] The installation assembly includes an installation box and a cover plate. The installation box is fixedly connected to the fixed platform of the drying oven and to the ventilation pipe. The cover plate is detachably connected to the installation box and is located on one side of the installation box.
[0011] The cover plate is provided with a plug-in plate, which is fixedly connected to the cover plate and detachably connected to the mounting box.

The device includes a drying oven top platform, a cooling equipment control cabinet, a mounting plate, an induced draft fan, an air supply assembly, and a mounting assembly.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows:
[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of a cooling device suitable for the high-temperature environment at the top of a drying oven. Figure 2 This is an overall top view of the equipment cooling device suitable for the high-temperature environment at the top of the drying oven. Figure 3 This is a diagram showing the installation of the cover plate. Figure 4 This is a schematic diagram of the air supply assembly. This utility model provides a cooling device suitable for high-temperature environments at the top of a drying oven: it includes a drying oven top platform 101, a cooling equipment control cabinet 102, a mounting plate 103, an induced draft fan 104, an air supply assembly, and a mounting assembly. The air supply assembly includes an air supply pipe 105, a connecting pipe 106, a ventilation pipe 107, and an air inlet pipe 108. The mounting assembly includes a mounting box 109 and a cover plate 110, with a plug-in plate 111 provided on the cover plate 110. The aforementioned solution addresses the issue that in summer, due to heat dissipation from the oven body and environmental factors, the installation environment of the microwave control system can reach 50°C to 60°C. At this temperature, venting air from the top of the oven to cool the microwave power supply and magnetron is ineffective, leading to frequent over-temperature faults in the microwave control system and operating power below the required process power. This reduces the drying capacity of the products, resulting in products failing to meet process requirements and posing quality risks. Understandably, the aforementioned solution facilitates cooling of the oven during summer use, increases the operating power of the microwave system, reduces quality risks in dried products, and improves drying efficiency.
[0022] In this specific embodiment, the cooling equipment control cabinet 102 is fixedly connected to the drying furnace top platform 101 and located on one side of the drying furnace top platform 101. The mounting plate 103 is fixedly connected to the drying furnace top platform 101 and located on the side of the drying furnace top platform 101 near the cooling equipment control cabinet 102. The induced draft fan 104 is fixedly mounted on the mounting plate 103. The air supply components are respectively mounted on the induced draft fan 104 and the cooling equipment control cabinet 102. The mounting components are mounted on the drying furnace top platform 101. The ambient temperature of the drying furnace platform is 50℃-60℃. The cooling equipment control cabinet 102 and the mounting plate 103 are mounted on the upper surface of the drying furnace platform. The induced draft fan 104 is fixed on the mounting plate 103 and located on the left side of the cooling equipment control cabinet 102. The induced draft fan 104 and the cooling equipment control cabinet 102 are connected through the air supply components. When the induced draft fan 104 is activated, it directly introduces air into the cooling equipment control cabinet 102, thereby cooling the top platform 101 of the drying oven to below 30°C. This ensures the normal operation of equipment such as the microwave power supply and magnetron, increases the operating power of the microwave system, reduces potential quality issues in the dried products, and improves the drying efficiency. The mounting assembly is located on the upper surface of the top platform 101 of the drying oven. The induced draft fan 104 and the cooling equipment control cabinet 102 are located within the mounting assembly, which enhances the cooling effect. During summer use of the drying oven, by installing the induced draft fan 104 and the cooling equipment control cabinet 102 on the top platform 101 of the drying oven, the cold air blower delivers cold air to the cooling equipment control cabinet 102 through the air supply assembly, allowing the cooling equipment control cabinet 102 to cool the top platform 101 of the drying oven, increasing the operating power of the microwave system, reducing potential quality issues in the dried products, and improving the drying efficiency.
[0023] The air supply duct 105 is connected to the induced draft fan 104; one end of the connecting pipe 106 is connected to the air supply duct 105, and the other end of the connecting pipe 106 is connected to the cooling equipment control cabinet 102; the ventilation duct 107 is connected to the air inlet of the induced draft fan 104; the air inlet duct 108 is fixedly connected to the ventilation duct 107 and located on one side of the ventilation duct 107; the air supply duct 105 is connected to the induced draft fan 104 through a flange; and the cooling equipment control cabinet 102 is connected to the air supply duct 105 through the connecting pipe 106, so that after the induced draft fan 104 starts, the airflow is delivered to the connecting pipe 106 through the air supply duct 105. Finally, the air enters the cooling equipment control cabinet 102. The ventilation pipe 107 is fixed to the air inlet of the induced draft fan 104 through a PP flange. The ventilation pipe 107 is a 0.5-meter diameter PP duct. The end of the ventilation pipe 107 is connected to the air inlet pipe 108, which is a 1-meter diameter PP duct. The ventilation pipe 107 and the air inlet pipe 108 are welded together with PP. The ventilation pipe 107 is completely independent of the drying oven platform, preventing the penetration of hot air from the space environment. Cold air enters the ventilation pipe 107 through the air inlet pipe 108 and is then transported to the cooling equipment control cabinet 102 by the induced draft fan 104, thereby cooling the top platform 101 of the drying oven.
[0024] Secondly, the mounting box 109 is fixedly connected to the fixed platform of the drying oven and to the ventilation pipe 107; the cover plate 110 is detachably connected to the mounting box 109 and is located on one side of the mounting box 109. The mounting box 109 is fixed to the upper surface of the top platform 101 of the drying oven. The mounting box 109 is a frame structure. The mounting box 109 covers the induced draft fan 104 and the cooling equipment control cabinet 102, providing them with closed working conditions. The left side of the mounting box 109 is penetrated by the ventilation pipe 107, which enables air intake. The cover plate 110 is placed on top of the mounting box 109. The cover plate 110, together with the mounting box 109, seals the induced draft fan 104 and the cooling equipment control cabinet 102, preventing the penetration of hot air from the space environment.
[0025] Meanwhile, the plug-in plate 111 is fixedly connected to the cover plate 110 and detachably connected to the mounting box 109. The plug-in plate 111 is fixed to the lower surface of the cover plate 110. The size of the plug-in plate 111 is smaller than the size of the cover plate 110. The size of the plug-in plate 111 is adapted to the internal size of the mounting box 109, so that the plug-in plate 111 can be inserted into the mounting box 109, and the cover plate 110 covers the mounting box 109, improving the stability of the cover plate 110 and preventing the penetration of hot air from the space environment.
[0026] When using the equipment cooling device suitable for high-temperature environments at the top of a drying oven according to this embodiment, during the summer use of the drying oven, by setting the induced draft fan 104 and the cooling equipment control cabinet 102 on the drying oven top platform 101, the cold air fan delivers cold air to the cooling equipment control cabinet 102 through the air supply component, thereby cooling the drying oven top platform 101, increasing the operating power of the microwave system, reducing potential quality problems of the dried products, and improving the product drying efficiency.
[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
