3000 tph capacity stacking and reclaiming system for power plant
1.Summary introduction
Bucket wheel stacker reclaimer can perform the functions of
continuous stacking, reclaiming, blending and storage of bulk
particles and block raw materials. It is widely used in the
material storage and transportation system of electric power,
metallurgy, building materials, chemical industry, port, coal,
grain and other industries. It is a common equipment in large and
medium-sized industrial enterprises.
Bucket wheel stacker reclaimer is mainly composed of bucket wheel,
slewing, boom raising, walking, cantilever belt conveyor, and metal
structure, tail car, auxiliary structure, central hopper, spray
dust suppression system, lubrication system, electrical system,
power supply device and so on.
By adjusting the tail car structure (fixed single tail car, semi
lying tail car, full lying tail car, cross tail car, double tail
car, etc.), the bucket wheel stacker reclaimer can realize many
functions, such as stacking, reclaiming through, reclaiming turn
back, shunting, through and so on, so as to meet the requirements
of different working conditions.
2.Structural form of the whole machine
The medium and small sized bucket wheel machines adopt the overall
balance form, with few movable hinge points and low failure rate.
The central hinge seat of the superstructure is equipped with
lubrication free joint bearing, with less maintenance workload. For
large bucket wheel machines, the movable balance type is mostly
adopted, mainly considering that the pitching angle of the
cantilever frame is small and the change of the center of gravity
relative to the superstructure is small.

3. Main parts of the stacker and reclaimer
1.Traveling mechanism
Three in one reducer with single
2.Bucket wheel mechanism
3. Luffing mechanism
(1)Bucket wheel mechanism generally adopts hydraulic transmission
and hydraulic cylinder pitching. The pitching motion is smooth
without impact. Ensure that there is no leakage in the hydraulic
system.
(2)The main components of the hydraulic system are international
famous brand products.
(3)Double acting differential hydraulic cylinder is adopted, and
maintenance free self-lubricating spherical sliding bearing is
installed at the hinge point of the cylinder. The upper and lower
oil inlet and outlet of the oil cylinder are equipped with anti
pipeline burst valves. When the pipeline breaks, the oil cylinder
will be automatically locked, and the cantilever will not fall, so
as to ensure the safety of the system.
(4)The boom is equipped with a safety rod. When repairing or
replacing the oil cylinder, the boom is fixed with the safety rod
to ensure the safety during maintenance.
(5)Safety device
- Two level limit switches are set at the upper and lower limit
positions of cantilever pitching.
- The pitching angle of the cantilever can be displayed in the cab.
- Both sides of the cantilever are provided with protective devices
to prevent the cantilever from colliding with the material pile.
- The whole oil circuit system is equipped with a safety device to
prevent oil pipe rupture.
