Using direct cycloid gear reducer, compact structure, reduces the speed of the hinge dragon, increases the output torque, can use a small power motor, thus reducing energy consumption. Because the humidifier adopts the structure of stirring blade and stirring bar, the humidification effect and production capacity will not be affected by the decline of speed. The stirring bar is made of special material, which is characterized by strong wear resistance and adhesion resistance. The machine by the feeder uniform feed flip strike humidification. The standard mixture with uniform mixing and humidification is pushed to the discharge port to achieve the purpose of solving secondary dust. The water supply of the machine is controlled by the valve group, and the main control cabinet is used to interlock the parts of the humidifier, so as to achieve the purpose of controlling the water supply and constant humidity operation.
