Jieneng New Era series environmental protection and energy saving automatic circulation hot air dryer ( Hereinafter referred to as dryer ) Sichuan Jieneng drying equipment Co., Ltd. is a newly developed drying equipment for cocoon drying by forced convection with hot air. It can also be used for drying other light and large particle materials by properly adjusting the temperature and speed of hot air Advanced and environmental protection equipment 。
working principle. After the cold air fed by the fan is heated to the required temperature by the hot blast stove, the hot air distribution system sends the cold air from the upper part and the middle part of the drying chamber according to the cocoon drying process requirements. The fresh cocoons are input to the top screen of the drying room through the automatic material laying device. Driven by the transmission mechanism, the cocoon moves with the screen and falls to the next layer of screen screen screen. In this way, the cocoon passes through the three temperature regions of high, medium and low successively Dry material is dried, and then it is cooled and packed outside the machine by the discharging machine. At the same time, part of the hot and humid air generated in the drying process is recycled to the hot blast stove for reheating, and most of it is discharged into the drying room or sent to the recycling device. The whole process is monitored and controlled by automatic control system.
The hot blast stove is an important equipment of this machine. In order to protect the hot blast stove from damage caused by excessive temperature of furnace body caused by improper operation or other reasons, the interlock protection of forced draft fan and combustion supporting fan is set.
In order to adapt to different drying process requirements ( Such as direct drying, first drying, second drying, different moisture content, etc ) The temperature, net speed, air supply volume and moisture discharge of the machine can be adjusted freely to achieve high quality process combination. The control system of the machine also has sound and light alarm for over high temperature or low total air temperature to remind operators to keep the drying temperature stable.
