The YJD-A type star discharger consists of a rotor impeller with several blades, a housing, seals, a reducer, and an electric motor, etc.
One, the upper and lower flange openings of the YJD-A type star discharge valve are generally square or round, or can be selected by the user.
When the material in the upper storage bin falls due to its own weight, it fills the gaps between the blades and is discharged at the bottom as the blades rotate. Therefore, the star-type ash unloading valve can discharge the material quantitatively and continuously.
Section 3: Damper Enclosed Rotor Blade Type Star-shaped Ash Discharge Valve This type of valve features a sealing strip at the end of the rotor blades, ensuring a good contact between the blade end and the inner wall of the housing. After wear, the blade end can be easily adjusted to maintain a good contact with the internal housing, providing excellent gas locking performance.
Four, the YJD-A type star-type discharger is commonly used in pneumatic conveying systems. For pressure conveying systems or negative pressure conveying systems, the YJD-A type star discharger can supply material to the conveying pipe uniformly and continuously. This ensures a stable ratio of gas to solids within the conveying pipe, allowing for normal operation of the pneumatic conveying. Additionally, it can isolate the upper and lower air pressure of the ash unloading valve, thereby serving as an airlock. Therefore, the YJD-A type star discharger is an important component commonly used in pneumatic conveying systems.
Five, Temperature-resistant model: The material temperature it can handle is up to 280°C. The two-end bearings and impeller are isolated, preventing the powder from contacting the bearings. The type of ash unloading valve can handle material temperatures up to 500°C, utilizing a sprocket connection, and there is a certain distance between the reducer and the ash unloading valve housing.
Six, the YJD-A type star discharge valve can be used in material collection systems as a hopper unloading valve. The YJD-A type star discharge valve is a commonly used unloading device in China, frequently employed in dust removal systems as one of the key equipment. It is particularly suitable for dust and fine particle materials, and is widely chosen for engineering projects in industries such as environmental protection, metallurgy, chemicals, grain, cement, road construction, and drying equipment.
YJD-A Star-type Ash Discharging Valve Features:
1) By employing the planetary rotation principle, the input and output are on the same axis, and there is an integral direct connection with the motor, resulting in a compact structure, aesthetically pleasing design, small size, and light weight.
2) Smooth operation, low noise, minimal failure, long lifespan. Gear components are made of spheroidal cast iron and bearing steel, offering excellent performance and durability.
3) Bearings, gearbox, and away from valve bodies, resistant to the effects of high temperature and dust; front and rear end caps provide excellent sealing performance, preventing dust leakage, and extending the service life of moving parts and the lubrication system.
4) This machine features overload capacity, low inertia torque, and is suitable for frequent starting and reversing.
5) For special specifications, unloaders such as motors, sprocket drives, etc., please contact our factory, all can be custom-made.
