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.

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.
