Flange Square Inlet Outlet Unloading Valve Rigid Impeller Feeder
I. Overview.
YJD series Rigid Impeller Feeder, also known as electric ash unloading valve, is composed of motor
needle wheel cycloid needle (Z) and rotary dragon type unloader.
There are two series and 60 specifications. The square of the
flange is type A and the round one is type B.
The Rigid Impeller Feeder 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. Compact structure, beautiful shape and easy to use.
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. Our factory can also be made according to customer requirements
(bracket coupling belt chain drive)
II. Working principle and structural characteristics
Rigid Impeller Feeder is composed of shell, impeller and end cover. The reducer,
transmission shaft and impeller are combined into one, which is
reliable, light and energy-saving. As the bearings and reducer of
this machine are protruding outward, it can avoid the phenomenon of
dust squeezing into the bearings and large granular material
jamming.
III. Instructions for use
1. Check whether the motor wiring is correct and reliable before
use, and whether to install overload protection.
2. This product has been added No. 00 lithium grease before leaving
the factory.
3. This product is suitable for powder dry materials and fine
particle dry materials, such as high humidity and high viscosity
materials, high temperature materials need to be customized
separately.
4. The safety should be paid attention to when starting, and the
hand should not be extended to the rotor part.
