Description
Technical field
The present invention relates to a kind of SUPPLEMENTARY UNLOADING GRAIN, be specifically related to a kind of run coal bin SUPPLEMENTARY UNLOADING GRAIN.
Background technology
Because the ature of coal coal of coal-burning power plant is complicated and changeable, and the reason such as warehouse entry moisture content of coal is high, viscosity is large, run coal bin chute blockage, fluffy coal, wall sticking phenomenon are frequently occurred, general canopy coal seam is extended down to run coal bin top cylinder or square tube part from the side of run coal bin bottom conical section is upwards fluffy, not only affect the smooth operation of boiler of power plant, and cause run coal bin actual library capacity to reduce, coal handling system is had to long-play; Meanwhile, when run coal bin and upstream device maintenance, long-pending coal slump brings potential safety hazard.At present, deposit coal in cleaning run coal bin, general adopt artificial lower storehouse cleaning, not only service conditions is severe, labour intensity is high, work capacity is large, and clearance time is long, and belongs to high-risk operations.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of simple, efficient, the run coal bin SUPPLEMENTARY UNLOADING GRAIN of run coal bin inner product coal can be cleared up safely.
For achieving the above object, technical scheme of the present invention is: a kind of run coal bin SUPPLEMENTARY UNLOADING GRAIN, is characterized in that: comprise jacking system, pneumatic exciting arch breaking apparatus and integrated control unit; Described jacking system connects pneumatic exciting arch breaking apparatus; Described jacking system, pneumatic exciting arch breaking apparatus are controlled by integrated control unit; Described jacking system comprises winch, lifting wire rope, location auxiliary rope and fixed pulley; Described pneumatic exciting arch breaking apparatus comprises strength vibration excitor and secondary Arch-Breaking Device, and strength vibration excitor is welded on the upper end of secondary Arch-Breaking Device; Described integrated control unit comprises compressed air gas source, overall-in-one control schema case and gas source pipe.
Described secondary Arch-Breaking Device top is the structure of the cylinder vertex of a cone, and bottom is the structure of long thin cylinder, bottom wedge shape.
Described lifting wire rope, location auxiliary rope to be stretched pneumatic exciting arch breaking apparatus by fixed pulley.
The top of described strength vibration excitor is provided with suspension ring.
Principle of work: overall-in-one control schema case starts, after three-point fix by lifting wire rope, location auxiliary rope and the thin cylindrical wedge body in secondary Arch-Breaking Device bottom, strength vibration excitor to shake to inside, coal seam by certain frequency drives secondary Arch-Breaking Device and discloses, make the downward landing of the destroyed dispersion in coal seam of bonding or knot arch, discharge from run coal bin outlet, thus the long-pending coal of cleaning.
As shown from the above technical solution, the invention has the beneficial effects as follows: it is strong that 1, reasonable in design, structure is simple, use safety, work efficiency are high, broken arch brings down stocks ability, need not manually clear up by warehouse entry.2, adopt secondary Arch-Breaking Device, the thin cylindrical wedge body of lower minister can be easy to insert coal seam, plays location, improves the broken arch degree of depth and efficiency; Upper cylindrical cone can expand the broken arch cleaning face in coal seam gradually.3, locate auxiliary rope and can assist three-point fix.4, adopt the pneumatic exciting arch breaking apparatus of strength air cylinder driven, meet the explosion-proof needs of run coal bin.
