After the utility model installation comes into operation, when slag muck product position is in below feed bin absolute altitude, the pressure of detection inserting tube output
Power one is set to negative pressure, if when slag muck product position reaches absolute altitude and slightly above absolute altitude, due to now detecting the loudspeaker of inserting tube end
Mouth has been flooded by material, and original negative pressure now will be no longer maintained at detection mouth and becomes malleation, can accurately detect material
Level of filler material in storehouse.During use, compressed air is passed through by jet pipe, period purge is carried out to detection inserting tube, prevents loudspeaker
Mouth blocks and adhesion.
The beneficial effects of the utility model are：
1st, it is simple in construction, make, be easy for installation, cost is low, and equipment fault can be substantially reduced after use, and larger reduction is set
Standby maintenance cost, it is ensured that equipment stable operation；
2nd, can efficiently solve level meter mounting bracket come off jam batcher, conveying worm the problem of, and feeler lever
The problem of measurement of adhesion accumulated slag is inaccurate；
3rd, signal display apparatus can use DCS system, and high and low level signals are just shown on monitoring interface for operation
Operating personnel's monitoring, judge.The signal can also be delivered to the related rotation equipment such as batcher, conveying worm, as interlocking/
Barring condition, relevant device is automatically controlled.
