Rotary discharge valve is commonly known as shut-off fan, impeller feeder, star feeder, air lock, rotary feeder, etc. It is composed of a rotor with several blades, a shell, a seal, a motor, a reducer, etc. composition. When the rotor rotates in the cylindrical casing, the material falling from the upper hopper by its own weight is packed in the spaces between the blades and discharged to the lower part as the rotor rotates, so as to realize uniform and continuous conveying of materials.
The rotary discharge valve has the characteristics of compact structure, beautiful appearance, good air-locking performance, stable work, uniform blanking, light and energy-saving, etc., which can play the role of feeding and locking the air flow. Due to the low-speed rotation of the rotor and the rotor and the shell The very small gap in the cavity effectively prevents the reverse flow of the airflow, thus ensuring the stability of the air pressure in the system and the normal discharge of materials.
The rotary discharge valve is the key equipment in the pneumatic conveying system. For the positive pressure conveying system or the negative pressure conveying system, the rotary discharge valve can uniformly and continuously supply material to the conveying pipe. The rotary discharge valve is very suitable for positive and negative pressure pneumatics. Conveying system, pulse dust removal equipment and gravity unloading and feeding occasions.
According to the characteristics of the materials, uses and conditions of use, the rotary valve has a variety of structural types, and its selection should be determined according to the characteristics of the conveyed materials such as particle size, adhesion, temperature, humidity, etc.
