Rotary valve for dust collection and HVAC applications.

 Capacity: 2~66L/Round

Speed: 24 Round/Minute

Working temperature: ≤300 *C

 

1. Working Principle:

This airlock valve, or named rotary valve. with several blades rotor rotating in a barrel enclosure, the material which dropped down from the top, to fill up the blanks among the blades, it will be discharged through the rotating of blades. rotary airlock systems allow free flowing solids to pass from one valve space to another valves space with a different air pressure.

2. Application:

The airlock valve is applied to discharge granulator/powder material or add granulator/powder material either in different positive air pressure or in different negative air-pressure of pneumatic conveying system, also it is a necessary device for ventilation and removing dust system. A rotary valve is of no use by itself. Rotary airlock, and rotary valves are useful as one component in a bulk or specialty material handling system. Rotary Airlock Feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: cement, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals and so on.

Application Areas:

(1).Silo Discharge:-The rotary valve placed under the silo or dust collection system is used to control the bulk solid discharge.
(2).Dosage Control:-By controlling the rotation speed of the airlock feeder, volumetric metering and dosing of granular solids is achieved.
(3).Pneumatic Transportation:-The airlock mounted under a cyclone is used for discharging the cyclone.
(4).Pneumatic Transportation:-Rotary valves mounted under cyclones, silos or hoppers are used to feed the pneumatic conveying line.

 

3.Characteristics:

(1) Usually it is composed of three-phrase AC asynchronous motor, motor reducer and rotary valve.

(2)It can work stably with high efficiency

­(3)With external bearings and motor-reducer, it can work under 280 °C.

­(4)The material can be cast iron,carbon steel, stainless steel;

­- Rotors can be made especially according to users requirement.

- Minimum gap between blade and body can lock the air efficiently.

- Driving method can be direct model or chain model.

- ­Widely used in chemical, cement, pharmacy, iron   & steel and foodstuff industry etc.

- Precision machining of the components
