[0029] like Figure 1 As shown, an anti-condensation wind curtain device is characterized in that it includes: a hot top 3, a first wind curtain 12, a second wind curtain 8, and an adjustable air outlet 9. The hot top 3 is fixedly installed on the top of the drying room 1. The hot top 3 is in a rectangular shape and is a closed structure. The top of the hot top 3 is provided with a first air inlet 7, and the bottom sides of the hot top 3 are respectively provided with a first air outlet and a second air outlet. The front side of the drying room 1 is provided with a workpiece entrance and exit 2. The first wind curtain 12 and the second wind curtain 8 are both in a rectangular shape. The first wind curtain 12 and the second wind curtain 8 are respectively installed on the left and right sides of the drying room 1. The top of the first wind curtain 12 is provided with a second air inlet 10, and the top of the second wind curtain 8 is provided with a third air inlet 11. The first wind curtain 12 is provided with a plurality of adjustable air outlets 9 on the side opposite to the second wind curtain 8 for adjusting the wind direction, wherein the first air outlet is connected to the second air inlet 10, and the second air outlet is connected to the third air inlet 11.

[0030] Among them, the hot roof 3 and the wind curtain are both fully welded to ensure the sealing of the wind curtain and the hot roof 3.

[0031] like Figure 2As shown, a first partition plate 5, a second partition plate 4 and a third partition plate 6 are installed in the hot top 3, the first partition plate 5 is arranged in parallel and staggered with the second partition plate 4 and the third partition plate 6, the first partition plate 5 is located between the second partition plate 4 and the third partition plate 6, the left end, the top and the bottom of the first partition plate 5 are tightly connected to the inner wall of the hot top 3 respectively, there is a gap between the right end of the first partition plate 5 and the inner wall of the hot top 3, the first air inlet 7 of the hot top 3 is located at the top of the gap, the right end, the top and the bottom of the second partition plate 4 and the third partition plate 6 are tightly connected to the inner wall of the hot top 3 respectively, there is a gap between the left end of the second partition plate 4 and the third partition plate 6 and the inner wall of the hot top 3 to provide a guide port for the flow of wind, an air inlet channel is formed between the first partition plate 5 and the second partition plate 4 and the third partition plate 6 respectively, an air outlet duct is formed between the second partition plate 4 and the third partition plate 6 and the inner wall of the hot top 3 respectively, and the second air outlet is located in the air outlet duct. By arranging partitions in the hot roof 3 , the hot air can be fully circulated inside the hot roof 3 , so that the surface temperature of the hot roof 3 is uniform, and condensation is prevented from being generated on the surface of the hot roof 3 due to uneven temperature.

[0032] Specifically, the length of the first air curtain 12 and the second air curtain 8 are both 2500 mm, and the width of the first air curtain 12 and the second air curtain 8 are both 550 mm. It should be noted that the length cannot be used to limit the protection scope of the present invention, and the size of the air curtain is adaptively designed according to the size of the drying room 1.

[0033] Preferably, the number of the adjustable air outlets is two, and the number of the air outlets is also set according to the length of the wind curtain. The longer the wind curtain is, the more adjustable air outlets 9 there are, ensuring that the spacing design of about 800 mm is the optimal design.

[0034] Specifically, Figure 3 and Figure 4 As shown, the adjustable air outlet 9 includes a first air outlet plate 904, a second air outlet plate, a hinge 903, a fixed base 901, and a bracket 902.

[0035] Specifically, the sizes of the first tuyere plate 904 and the second tuyere plate are respectively the same as the sizes of the adjustable tuyere 9 .

[0036] Specifically, the movable angles of the first tuyere plate 904 and the second tuyere plate are both 0-120 degrees.

[0037] Specifically, the first tuyere plate 904 and the second tuyere plate each include a first baffle plate 906 and a second baffle plate 907, one end of the first baffle plate 906 is connected to the bracket 902 via a hinge 903, and the middle of the first baffle plate 906 is connected to the second baffle plate 907 via a bolt 905.

[0038] Specifically, the first baffle 906 and the second baffle 907 are both L-shaped and have the same direction.

[0039] Specifically, the first air curtain 12 and the second air curtain 8 are made of stainless steel, which can prevent rust and corrosion by high-temperature solvents.

[0040] Working method: The hot air outside the drying room enters the hot top cavity from the first air inlet of the hot top. There are multiple partitions in the hot top, which divide the hot top into multiple air ducts. The hot air circulates in the air ducts to evenly heat the surface of the hot top to prevent uneven hot and cold from causing high-temperature solvent vapor to condense on the surface of the hot top. The air inlets of the first air curtain and the second air curtain are respectively connected to the hot top. The hot air enters the wind from the hot top and is blown to the entrance and exit of the drying room through the adjustable air outlet at a certain wind speed and direction, so that the temperature at the entrance and exit of the drying room can be maintained between 140-180 degrees, thereby preventing the exchange of hot air in the drying room and cold air at the entrance and exit of the drying room, and also preventing the generation of condensate.

[0041] The invention has a simple structure. By arranging a hot top and a first air curtain and a second air curtain, and connecting the first air curtain and the second air curtain, the heat exchange between the high-temperature solvent vapor in the drying room and the cold air at the outlet of the drying room is effectively prevented, and the generation of condensate is prevented. In addition, a first baffle, a second baffle and a third baffle are arranged in the hot top to ensure that the hot air in the hot top circulates evenly, and the surface of the hot top is evenly heated to prevent condensate from being caused by uneven cold and heat on the surface of the hot top. In addition, an adjustable air outlet is arranged at the air outlet of the first air curtain and the second air curtain. The adjustable air outlet includes a first air outlet plate, a second air outlet plate, a hinge, a fixed base and a bracket. The fixed base is installed at both ends of the inner side of the adjustable air outlet. The bracket is fixedly installed on the outer side of the adjustable air outlet corresponding to the fixed base and fixedly connected by bolts. The first air outlet plate and the second air outlet plate are installed on both sides of the adjustable air outlet and are movably connected to the bracket by hinges. The angle at which the wind from the air curtain blows to the inlet and outlet of the drying room can be manually adjusted to ensure that the temperature of the inlet and outlet of the drying room is almost the same as the indoor temperature in the drying room, thereby effectively preventing the generation of condensate.
