Description

Technical Field

[0001] The utility model relates to the technical field of paper production equipment, in particular to a hot air hood which can accelerate the drying speed of paper. Background Art

[0002] Paper is a common commodity in daily life. Wet papermaking is a commonly used paper manufacturing method. Wet papermaking requires multiple processes. After mechanical dehydration, there is still a lot of moisture in the paper, which must be removed by drying. The hot air hood used for paper drying is a device that can speed up the paper drying speed. When the paper is dried through the hot air hood, the hot air has a high wind speed at the outlet of the hot air hood and the hot air in the hot air hood is unevenly distributed when it flows out, which may cause the paper to move and fold, requiring later sorting or even causing the paper to be scrapped, increasing costs.

[0022] Example

[0023] Reference Figure 1-6 As shown,

[0024] A hot air hood capable of accelerating paper drying speed comprises a processing table 1, the processing table 1 is arranged parallel to a horizontal plane, a hood body 2 is arranged above the processing table 1, two air inlets of the hood body 2 are both connected to a connecting air duct 3, an electromagnetic valve 301 is arranged on the connecting air duct 3, a plurality of air outlets are opened on the arc surface of the hood body 2 close to the processing table 1, the air outlets are evenly distributed, a speed reduction mechanism 4 is fixedly arranged in the air outlet, a wind speed sensor 406 is arranged in the speed reduction mechanism 4, and an end of the connecting air duct 3 away from the connecting air duct 3 is connected to an air outlet end of a hot air generator;

[0025] The hot air of the hood body 2 is generated by a hot air generator and blown out from the air outlet through the connecting air duct 3 to dry the paper on the processing table 1. A deceleration mechanism 4 is arranged in the air outlet of the hood body 2. The hot air can reduce its wind speed when passing through the deceleration mechanism 4. The staff can control the flow rate of the hot air through the electromagnetic valve 301. The staff can control the flow rate of the hot air from the hot air generator entering the hood body 2 by controlling the electromagnetic valve 301. The greater the hot air flow rate, the greater the wind speed blowing out of the deceleration mechanism 4.

[0026] The deceleration mechanism 4 includes a fixed cylinder 401, a stainless steel filter 402, a fixed shaft 403, a rotating ring 404, blades 405 and a wind speed sensor 406. The outer wall of the fixed cylinder 401 is fixedly connected to the air outlet of the wind hood body 2, and the two ends of the fixed cylinder 401 are communicated. The stainless steel filter 402 is fixedly arranged at both ends of the inner wall of the fixed cylinder 401. A fixed shaft 403 is fixedly arranged between the stainless steel filter 402. The fixed shaft 403 passes through the rotating ring 404 and is rotatably connected to the rotating ring 404. A plurality of blades 405 are fixedly arranged on the outer wall of the rotating ring 404. The blades 405 are arranged in a circular array. The outer wall of the fixed shaft 403 is fixedly arranged with a wind speed sensor 406. The wind speed sensor 406 is arranged between the rotating ring 404 and the stainless steel filter 402 close to the wind hood body 2.

The hot air drives the fan blade 405 to rotate, thereby reducing the hot air speed, and the rotation of the fan blade 405 will drive the hot air to enter between the hood body 2 and the processing table 1 more evenly, so that the paper is heated more evenly and the drying rate of the paper is improved. The wind speed sensor 406 is used to monitor the hot air speed in real time. The maximum wind speed that different papers can withstand is different. The staff controls the electromagnetic valve 301 to adjust the wind speed of the hot air blowing speed reduction mechanism 4 according to the different papers. Stainless steel filters 402 are set on both sides of the fan blade 405 to prevent dust from entering the fixed cylinder 401.

[0028] The fixed shaft 403 passes through the two limit plates 4031 and is fixedly connected to the limit plates 4031. The two limit plates 4031 are arranged on both sides of the rotating ring 404.

[0029] The limiting ring limits the rotating ring 404 , preventing the rotating ring 404 from moving randomly along the fixed axis 403 .

[0031] Stainless steel has high hardness and strength, is not easy to absorb dust and dirt, is easy to clean and maintain, and is resistant to high temperatures and can withstand the temperature of hot air.
