Problems solved by technology
[0003] 1) The powder is easy to agglomerate, the degree of drying is uneven, and the efficiency is low
[0004] 2) When drying powder in a traditional oven, the powder needs to be placed in a heat-resistant container, and high-temperature-resistant gloves are required to take it out. During the powder transfer process, there is a risk of burns
[0005] 3) If the powder is directly spread in the oven, it is not easy to take out the powder

The invention provides a hot air drying type powder coating drying device and a powder coating drying method. The hot air drying powder coating drying device includes a drying chamber, which is provided with a hot air inlet and an air outlet for introducing hot air for drying. The hot air inlet is equipped with a one-way valve; the air outlet is equipped with a filter device; It also includes a hot air supply system. The hot air supply system includes sequentially connected fans, preheaters and intermediate boxes. The air outlet of the intermediate box is connected to the hot air inlet. It also includes a support frame, and the bottom right end of the drying chamber is hinged to the support frame. , a cylinder is also hinged on the support frame, the piston rod of the cylinder is hinged with the bottom of the left end of the drying chamber; the right end of the drying chamber is a material port, and the material port is detachably connected with a cover. This patent uses hot air to dry the powder, which realizes the powder flying in the drying chamber and the timely output of water vapor, which improves the drying uniformity of the powder and avoids the problem of agglomeration.
Description
technical field [0001] The invention relates to the field of mechanical technology, in particular to a powder drying device and a drying method. Background technique [0002] In the production of oil pipeline inner coating products, in order to ensure the construction quality, it is necessary to dry the powder coating. Traditionally, the oven is mainly used for drying the powder. Traditional oven drying has the following defects: [0003] 1) The powder is easy to agglomerate, the degree of drying is uneven, and the efficiency is low. [0004] 2) When drying powder in a traditional oven, the powder needs to be placed in a heat-resistant container, and high-temperature-resistant gloves are required to handle it when taking it out. During the powder transfer process, there is a risk of burns. [0005] 3) If the powder is directly spread in the oven, it is not easy to take out the powder. Contents of the invention [0006] Aiming at the problems existing in the prior art, t...
