Discharger

As a kind of environmental protection equipment, star discharge valve is widely used in metallurgical, chemical, grain, cement, road construction, drying equipment and other industrial projects, so it is also known as the discharger.

Product overview

As a kind of environmental protection equipment, star discharge valve is widely used in metallurgical, chemical, grain, cement, road construction, drying equipment and other industrial projects, so it is also known as discharger, rotary feeder, air lock valve. The structure of star discharge valve is composed of rotor, impeller, shell, seal, reducer and motor with several blades. When the material in the upper bin falls by its own weight and fills the gap between the blades, the upper part is discharged with the rotation of the blades. Therefore, the star discharger can discharge the material quantitatively and continuously.

working principle

1、 Star type discharge valve is also called star type discharge valve, rotary feeder and air lock valve. Generally, the structure of discharge valve is composed of rotor impeller with several blades, shell, seal, reducer and motor.

2、 When the material in the upper bin falls by its own weight and fills the gap between the blades, it is discharged at the lower part with the rotation of the blades. Therefore, the discharger can discharge the material quantitatively and continuously.

3、 Star type discharge valve is commonly used in the conveying of bulk, particle and powder materials. For the positive pressure output system or negative pressure output system, the discharge valve can uniformly and continuously supply materials to the conveying pipe, so as to ensure that the materials in the output pipe are stable, so that the conveying of bulk materials can work normally. At the same time, it can block the upper and lower air pressure of the discharge valve and play the role of air locking. Therefore, the discharge valve is an important part of pneumatic conveying system.

4、 The upper and lower flange openings of star discharge valve are basically square or round, which can also be selected by users.

5、 The characteristic of this type of discharger is that the end of the rotor blade is lined with polyfluoroethylene sealing strip or wear-resistant nitrile sealing strip, which can ensure that the end of the blade has good contact with the inner wall of the shell, and the end of the blade can be easily adjusted after wear, so that it still keeps good contact with the inner shell, and has better sealing performance.

6、 The temperature of the material transported by the high temperature resistant type can reach 280 ℃, and the bearings at both ends are isolated from the impeller to a certain extent, which can prevent the superfine powder from contacting with the bearing, so as to reduce the wear.

As a kind of simple and fast conveying equipment, star discharge valve has stable performance and is widely recognized by users.
