Handling Power Material Impeller Feeder Star Type Ash Unloading
Valve Cast Iron
I. Overview.
The Star Type Ash Unloading Valve is generally made of cast or welded carbon steel plate. It is one
of the main equipment for ash discharge of dust removal equipment
and other equipment. The electric ash unloading valve is divided
into normal temperature type and high temperature type, which is
composed of motor, gear difference planetary reducer or needle
fiber cycloid reducer and rotary discharger. It has two series and
60 specifications. The inlet and outlet flanges are type A and the
circular ones are type B.
The Star Type Ash Unloading Valve is the main equipment for dust discharge, air supply and other
equipment feeding, which is suitable for powdery materials and
granular materials, and is widely used in environmental protection,
metallurgy, chemical industry, grain, food and other industrial
sectors.
Characteristics are below:
a. The Star Type Ash Unloading Valve has high processing precision and air locking function. It can be
used as the quantitative feeder of powder in crushing and
classification systems, and as the unloader of separation, dust
collection and other systems.
b. Smooth operation and low noise.
c. Because the bearing and the tooth shell are at a distance from the
box, the high temperature lubrication has been greatly improved.
d. Cast iron, cast steel, stainless steel, titanium steel and other
materials can be used, and the flange can be square or circular and
other structural forms to meet the different needs of users.
II. Working principle and structural characteristics
The star type ash unloading valve is rotated in the cylindrical casing by the rotor with several
blades. The materials falling from the upper hopper are filled in
the space between the blades and discharged with the rotation of
the blades. The valve can be made of cast iron, cast steel,
stainless steel, titanium steel and other materials. The flange
port can be square or circular and other structural forms to meet
the different needs of users.
