Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to a novel double-gas-sealed structure for drying ovens. Background Technology

[0002] A drying oven is a device used to dry materials. It primarily works by generating hot air or hot gas through heating, causing the moisture in the material to evaporate, thus achieving the drying purpose. Drying ovens are widely used in various industrial production and daily life, characterized by high efficiency and energy saving. Before use, a drying oven needs to be air-sealed; therefore, a new type of double-air-sealing structure for drying ovens is designed.

[0003] When using the new type of drying oven with a dual-air-seal structure, the existing technology makes it difficult to simultaneously dissipate internal heat and allow external cold air to enter during the air-seal process, resulting in the air-sealing effect not meeting expectations. Utility Model Content

[0004] The purpose of this invention is to provide a novel double-air-sealed structure for drying ovens. By adopting a double-air-sealed structure, the overflow of hot air inside the drying oven and the direct entry of cold air outside the oven into the oven are reduced, thereby maximizing the stability of the oven temperature.

[0005] To achieve the above objectives, a novel double-air-sealed structure for a drying oven is provided, comprising a drying oven chamber, wherein a first air curtain vent device and a second air curtain vent device are respectively arranged on the inner side of the drying oven chamber, and a first folding plate, a second folding plate, and a third folding plate are arranged intersectingly between the first air curtain vent device and the second air curtain vent device.

[0006] According to the novel double-air-sealed structure of the drying oven, the first air curtain vent device and the first folding plate are fixedly connected to each other.

[0007] According to the novel double-air-sealed structure of the drying oven, the second air curtain vent device and the second folding plate are fixedly connected to each other.

[0008] According to the novel double-air-sealed structure of the drying oven, multiple wall panels are fixedly connected between the first folding plate, the second folding plate, and the third folding plate.

[0009] According to the novel double-air-sealed structure of the drying oven, a first baffle and a second baffle are symmetrically fixedly connected between the first air curtain vent device and the first folding plate, respectively.

[0010] According to the novel double-air-sealed structure of the drying oven, an air curtain adjustment plate is installed between the first folding plate and the second folding plate.

[0011] According to the novel double-air-seal structure of the drying oven, an inspection door is installed on one side of the wall panel.

[0012] According to the novel double-air-sealed structure of the drying oven, the side wall of the drying oven chamber is symmetrically equipped with return air inlets and supply air inlets, and the return air inlets, supply air inlets and drying oven chamber are all connected and fixed.

[0013] Beneficial effects:

[0014] The dual-air-sealing structure consists of two sets of air curtain vent devices and multiple folding plates. The dual-air-sealing structure is installed at the top of the drying oven chamber. The first air curtain vent device is installed on the first folding plate, and the second air curtain vent device is installed on the second folding plate. The wall panel, the first folding plate, the second folding plate, and the third folding plate form a cavity. When hot air is delivered into the cavity through the air inlet, a hot top is formed at the top of the drying oven chamber. Hot air can only enter the drying oven through the first air curtain vent device, forming a hot air curtain. The hot air curtain prevents hot air from escaping from the drying oven and also prevents cold air from directly entering the drying oven. The second air curtain vent device and the first folding plate form a return cavity, further reducing hot air leakage. The first and second baffles respectively block possible hot air leakage from the bottom and top. The hot air returns to the heating device through the return air inlet, forming a hot air circulation. The dual-air-sealing structure reduces hot air leakage from the drying oven and prevents cold air from directly entering the oven, maximizing the stability of the oven temperature.

[0036] The drying oven chamber 10 has return air inlets 12 and air outlets 13 symmetrically installed on its side walls. The return air inlets 12, air outlets 13 and the drying oven chamber 10 are all connected and fixed.

[0037] Specifically: hot air is sent into the cavity through the air inlet 13 to form a hot top at the top of the drying oven chamber 10, and the hot air returns to the heating device through the return air inlet 12 to form a hot air circulation.

[0038] Working principle: The double-air-sealed structure consists of two sets of air curtain vent devices and a first folding plate 4, a second folding plate 6, and a third folding plate 7. The double-air-sealed structure is installed at the top of the drying oven chamber 10.

The wall panel 3, the first folding plate 4, the second folding plate 6, and the third folding plate 7 form a cavity. When hot air is delivered into the cavity through the air inlet 13, a hot top is formed at the top of the drying oven chamber 10. Only when the first air curtain vent device 1 forms a hot air curtain that is delivered into the drying oven chamber 10 can the hot air in the drying oven chamber 10 be prevented from escaping, and at the same time, external cold air be prevented from directly entering the drying oven chamber 10. The second air curtain vent device 11 and the first baffle plate 4 form a return cavity, further reducing the escape of hot air. The first baffle plate 8 and the second baffle plate 9 respectively block the possible escape of hot air from the bottom and top. The hot air returns to the heating device through the return air port 12, forming a hot air circulation. The double air seal structure reduces the escape of hot air in the drying oven and the direct entry of external cold air into the oven, maximizing the stability of the oven temperature.
