Repairing inconvenience or even some maintenance can not carry out.
2, measured deviation.Some instrument cannot be installed as required by spacial influence, may influence measurement effect, reduce accurate
Degree.
3, technique change is more troublesome.Due in actual production and design there may be some deviations, in finishing operations
It needs to carry out some technique changes, but device characteristic, may cause technique change and be difficult to carry out.
4, inspection is inconvenient.Space is small, compact arrangement of equipment, and inspection is more troublesome.
Summary of the invention
The utility model proposes feeder air rapping apparatus, can expeditiously shake in time to coal bunker when feeder produces coal
It beats, to prevent coal bunker from generating clogging when conveying coal.
The utility model uses following technical scheme.
Feeder air rapping apparatus, the rapping apparatus include disconnected coal signal pickup assembly, cylinder, solenoid valve, gas source,
PLC and multiple silo wall vibrating air hammers；The multiple height of the multiple silo wall vibrating air hammer point are set to coal bunker vertical side walls in couples
Outer surface；The disconnected coal signal pickup assembly is set to coal bunker exit；The gas source is connected with cylinder；The solenoid valve is set to
At the gas circuit of cylinder；Silo wall vibrating air hammer is connected with cylinder；When feeder carries out coal supply operation, if coal bunker exports disconnected coal,
Solenoid valve control cylinder drives silo wall vibrating air hammer impact coal bunker side wall so that the coal in coal bunker restores flowing.
The coal bunker vertical side walls are equipped with protective plate in the impact point of silo wall vibrating air hammer.
The solenoid valve connects the outlet pipe of silo wall vibrating air hammer by air inlet pipeline；The solenoid valve passes through preceding tracheae
It is connected to one end of cylinder, is connected to the other end of cylinder, rear tracheae and rapid escape valve by rear tracheae and rapid escape valve
Between be equipped with control valve；Cylinder is fixed on the base, and the piston rod in cylinder connects silo wall vibrating air hammer tup；The PLC
Timing, continuous vibration are realized through solenoid valve control cylinder driving silo wall vibrating air hammer.
When the solenoid valve is energized, the compressed air of gas source flows into cylinder, increases cylinder interior pressure, the piston with piston
The coal bunker side wall outer wall of head high-speed impact hammer body front end；When solenoid valve stops being powered, compressed air discharge, piston reset.
The disconnected coal signal pickup assembly includes non-contact switch, and the non-contact switch passes through the outlet of detection coal bunker
The coal contact mechanism posture at place is to determine whether there is disconnected coal phenomenon.
Horizontal insertion plate door is equipped in the middle part of the coal bunker.
Silo wall vibrating air hammer is equipped with above and below the insertion plate door.
Utility model has the advantages that
1 is high-efficient: a set of silo wall vibrating air hammer can substitute 10 work task efficiencies.
2 automatically control: being realized and automatically controlled by disconnected coal signal acquisition.
3 impact strength are big: beating frequency can be adjusted arbitrarily.Meet the requirement of different coal bunkers, different coals quality.
Accessible dredging in 4 storehouses: being not take up coal scuttle inner space, easy to maintenance, not will cause artificial chute blockage.
Since the pneumatic hammer of the utility model is uniformly controlled by PLC, can just unite when disconnected coal phenomenon just occurs
One ground executes rapping, prevents the further deterioration of coal bunker blocking, and can realize by the rapping frequency match of multiple pneumatic hammers
The resonance of coal bunker wall, to strengthen ramping effect.
