CDQ Furnace Rotary Seal Valve

Introduction of CDQ furnace rotary seal valve

CDQ furnace rotary seal valve is one kind of multi-squared seal feeder, installed below the CDQ furnace electro-vibrating feeder. Cycloidal pinwheel reducer driving the rotor of the CDQ furnace rotary seal valve rotates as a fixed direction, and the rotating rotor discharges CDQ from the CDQ furnace electro-vibrating feeder continuously and hermetically. This equipment can operate long-time and steadily under the CDQ below 200 degree centigrade.

Function of CDQ furnace rotary seal valve

CDQ furnace rotary seal valve discharges CDQ from the CDQ furnace electro-vibrating feeder continuously and uniformly.

Advantages of CDQ furnace rotary seal valve

  • Adopting wear-resisting material , with good lubrication and long service life. Redesign and optimize the fat pipeline; set testing system of reversing valve to alarm Anomalies; install the sight glass and purge device on the both sides of lateral cavity, to facilitate inspectors to observe the lubrication of sealing pair intuitively; adopt wear-resisting plate, and use the wear-resisting ceramics on some places, with a more long service life.
  • Adopting welding wire to surfacing directly instead of the installation of rotor blade on the partition, this avoids the falling off of the rotor blade, and controls the outside diameter tolerance effectively.
  • Using special screws on the checking hole, convenient to operation.
  • It can be controlled lonely, and also can be controlled with the PLC in the central control room. It is convenient to operate and overhaul.
  • It can be equipped with frequency control cabinet, then it can regulate speed and achieve soft starting, and protect the impact from opening and closing of inertia and extend the equipment lifetime.

Working principle of CDQ furnace rotary seal valve

When the driving device of CDQ furnace rotary seal valve receives the start signal, cycloidal pinwheel reducer rotates the active sprocket, then power transmits to driven sprocket which installed on the spindle of rotor under the driving of Sleeve roller, finally, the rotor of CDQ furnace rotary seal valve starts to rotate. When CDQ drops from the blanking tube and then enters into CDQ furnace rotary seal valve, throwing troughs throw CDQ to the next equipment. CDQ is sent to the next equipment uniformly. Through this way, the flow of CDQ can be controlled conveniently.

Structure of CDQ furnace rotary seal valve

It is mainly composed of valve body, driving device, mobile trolley and the up and down compensator.
