Description
Technical Field
[0001] The utility model belongs to the technical field of textile drying equipment, and more specifically relates to a quick pressing device suitable for the air distribution plate of a dryer, especially suitable for pressing the air distribution plate of a cylinder dryer in a non-woven fabric production line. Background Art
[0002] A dryer is a device that works based on the principle of heat convection transfer of hot air. The dryer uses hot air as a transfer medium to transfer heat to the material and evaporate the moisture in the material - that is, the heated hot air is blown by a circulating fan towards the entire drying chamber, and after passing through the upper and lower air distribution plates, it is blown towards the material on the surface of the cylinder. Then, the high-temperature hot air flow first penetrates the material and the cylinder, and then is drawn away by the circulating fan connected to the cylinder, and then recycled. In the actual production process, with the progress of technology, the production speed has been gradually increased, the output has been greatly improved, and correspondingly, the circulating air volume in the drying chamber needs to be greatly increased. The circulation times of the high-temperature air flow are also more frequent. In this way, the air distribution plate often falls off onto the cylinder under the action of the strong air flow. Coupled with the fact that the surface of the cylinder plate is punched with dense air holes with very small diameters and is covered with a layer of stainless steel wire mesh, the fallen air distribution plate will seriously damage the wire mesh on the surface of the cylinder, thereby affecting the normal operation of the equipment and the smooth progress of production. At the same time, it is only possible to enter the maintenance after the high-temperature drying chamber has cooled down to room temperature, and there are also defects such as difficult disassembly and replacement of the wire mesh, time-consuming and laborious, and expensive repair. Therefore, there is an urgent need to design a quick pressing device that can effectively prevent the air distribution plate from falling off onto the cylinder under the action of the strong air flow, avoid damaging the wire mesh on the surface of the cylinder due to the falling off of the air distribution plate, and more importantly, save the cumbersome disassembly, replacement and repair troubles after the wire mesh is damaged, ensure the normal operation of the equipment and the smooth progress of production.
