Background
Cyclone separators are commonly used medium separation systems in the industry field, and can realize the function of efficiently separating tiny particles mixed in air flow in the working occasion of gas conveying materials, and due to the influence of the working principle, a negative pressure space is always formed in the cyclone separators, so that the collected tiny particles are difficult to discharge under the condition that equipment is not stopped, and the existing ash discharge valve is difficult to completely seal.
Currently, there are several media separation devices:
the star-shaped ash discharging valve discharges the material and continuously feeds the material into the next device by means of the gravity action of the material and the forced action of the working mechanism of the feeder. The structure depends on the extrusion of the impeller and the inner wall of the cavity, but the sealing performance is poor because the impeller always rotates.
A screw feeder is a device for conveying a material in a semicircular trough concentric with the screw by rotation of the screw. The material in the trough does not rotate along with the spiral in movement due to the gravity and the friction force to the trough wall, but moves along the trough in a sliding mode, so that the material conveying function is realized. The structure of the sealing device cannot guarantee tight sealing for fine materials, and pressure leakage is easy to occur.
The existing star-shaped ash discharging valve or spiral feeder can realize continuous discharging action, but is limited by the working principle, and the two devices have the conditions of unreliable sealing, quick abrasion and easy scratching caused by large particle blocking, which cannot meet the working requirement of continuous separation.
