The discharge gate control mechanism has a manual, electric, and pneumatic three forms. Manual only for small mixers. Large and medium-sized mixer using electric or pneumatic control.
Electric control is by the electric actuator to open and close the discharge gate. It is mainly composed of an electric actuator, connecting rod and bump, and other components, the electric actuator reciprocates motion, through the connecting rod to drive the linkage shaft and discharge door rotation, so that the discharge door opens and closes. There are bumpers and limit switches on the electric actuator, when the actuator moves to the specified position, the bumpers contact the limit switches to make the motor run or stop running to protect the electric actuator. In addition, the bumpers on the linkage shaft rotate together with it, when the discharge door opens to the required position, the electric actuator stops moving, at this time, the bumpers are also installed in the upper limit of the body of the screw on top of the body to prevent the discharge door due to the self-weight or inertia effect of the continuous movement of the electric actuator is damaged.
The powder material adopts the pneumatic big door structure, which has the advantages of fast discharge and no residue. High fineness material or semi-fluid material selection manual butterfly valve or pneumatic butterfly valve, manual butterfly valve is economical, pneumatic butterfly valve for semi-fluid sealing is good, but the cost is higher than manual butterfly valve. According to needs, the screw belt mixer can also be equipped with butterfly valves, ball valves, star discharge valves, flap valves, knife gate valve side discharge valves, etc.
