Design Rotary Airlock Valve Cement Grain Star Unloader Ash Coal Mine Rigid Impeller Feeder
1. Introduction
The unloader is used to install in the negative pressure work of
the unloader discharge port, the upper part of the acceptance of
the unloader discharged materials, relying on the rotating impeller
plays a role in conveying materials, but also assume the role of
sealing, to prevent the pneumatic conveying process from the
discharge port inhalation of air, the unloader's normal discharge
as a special unloading equipment, in the cleaning and cleaning work
plays a great role. So we need to summarize some of its
characteristics, so you can better do a comprehensive understanding
of the unloader and maintenance, play its ability.
(1) The unloader is often used in the pneumatic output system, for
the pressure output system or negative pressure output system, the
unloader can be uniform, continuous material supply to the delivery
pipe. To pneumatic output pipe gas, solid is relatively stable, so
that the pneumatic conveying can work normally, at the same time,
but also will be able to unloader on the lower part of the air
pressure isolation and play a role in locking gas. Therefore, the
unloader is an important part commonly used in pneumatic conveying
system.
(2) Then the material of the upper silo falls by its own weight and
fills in the gap between the blades, it is discharged in the lower
part with the rotation of the blades. Therefore, the discharger can
quantitatively and continuously discharge materials.
(3) The unloader can be used in the collection of materials in the
system, as the unloader of the silo. The unloader is currently the
domestic into the unloading device, often used in the dust removal
system as one of the important equipment in the dust removal
system. It is especially suitable for dust, small particles of
material, by the environmental protection, metallurgy, chemical
industry, food, cement, road construction, drying equipment and
other industrial projects in the industry of choice.
(4) Temperature-resistant type, the temperature of the material it
conveys can reach 280°C. The bearings at both ends are isolated
from the impeller, which can prevent the ultra-fine powder from
contacting with the bearings. High-temperature type unloader
conveys materials at temperatures up to 500°C and adopts chain
wheel connection. There is a certain distance between the reducer
and the unloader shell.
2. The unloading device is divided into three parts, motor, cycloid
reducer and the rotary ash unloading valve.
(1) By adopting the principle of planetary rotation, the input and
output shafts are on the same axis, and there is the uniqueness of
being directly connected with the motor, thus the structure is
compact, the modeling is beautiful and novel, the volume is small
and the weight is light.
(2) Excellent sealing performance, uniform and stable feeding,
smooth discharging, low noise, less failure, long service life,
high wear resistance.
(3) Bearings, gear box, away from the valve body, to avoid the
influence of high temperature dust, before and after the end cover
sealing performance is good, to prevent dust leakage, to extend the
service life of the motorized parts, lubrication system.
(4) Strong overload capacity, impact resistance and small inertia
force, suitable for frequent starting and inverse rotation.
(5) According to the user needs to configure special special
motors, such as explosion-proof, frequency control, speed control,
marine motors, etc., in order to meet the user's special
requirements. In the material can also be according to user needs
for special processing, such as high temperature resistance,
corrosion resistance, stainless steel, flexible blade,
explosion-proof impeller.
