Fengxin technologys Yankee hood finally broke through the foreign blockade and realized domestic production

In the rapid development of modern society, science and technology are also in rapid development. Today, Yanke hood has successfully broken through the technical blockade of foreign countries and achieved domestic production.

The standard Yankee dryer hot air hood is a well-known product in the market. The hot air hood of this type of drying cylinder generally adopts impact drying. The air flow temperature can be as high as 200 ℃, and the air flow speed is 50-160m / s. The mechanical design from the transverse nozzle box to the pressure ventilation system can vary as required. The hot air hood can be dried under the condition of high impact temperature, and it can be divided into three independent areas: high temperature toe area, mixing area and drying area in the first area after making and pressing the Yankee hood. The temperature of these three areas can be adjusted respectively according to the requirements of quality and output (but now domestic manufacturers generally do two areas, namely high temperature toe area and drying area, which can save production costs, and also According to the domestic paper machine speed is not high.

According to the different types of paper produced by Yankee hood manufacturers, Yankee hood is generally divided into three specifications, i.e. hole plate type, strip type or hole slat type.

The operation side is equipped with a full-length electric lifting door, which is equipped with a full-length insulated glass window; the transmission test is equipped with a sliding door, and the door is also equipped with an insulated glass window, so the operation status of the paper machine is clear at a glance. The lifting door is provided with a interlock device with the paper break signal, once the paper break lifting door can be automatically lifted; of course, the lifting of the lifting door can also be manually operated on the console. A manual door for replacing the roller is opened on the operation side panel, and a vertical and horizontal manual hoist is arranged in the air hood, which can easily lead paper and change the roller. At the same time, the rope breaking protection device ensures the safety of personnel and the lifting door body.
