Quantity be two or more, between lever switch by electrical connection, be vertically successively set on coal store；
Multiple lever switches are set by the vertical direction of coal store, the different zones to coal store carry out segmentation inspection
Survey, it is to avoid coal cinder blocks the failure for causing anti-block apparatus outside the detection range of single lever switch, and coal cinder is deposited in coal store
When reserves are relatively low, the lever switch positioned at the top starts, and reminds staff to supplementing coal cinder in coal store.
In order to improve to the dredging effect of coal cinder in coal store and vibrations area, the quantity of the Rapping apparatus for two or
Two or more, by electrical connection between Rapping apparatus, is separately positioned on coal store；
By increasing the quantity of Rapping apparatus, the vibrating effect and vibrations area to coal store are improve.
For the ease of using shaking device, the Rapping apparatus to select vibrating motor；
It is Rapping apparatus by using vibrating motor, is easy to Rapping apparatus to be driven using electric power, it is to avoid to use fossil
The inconvenience that other driven by energy Rapping apparatus such as fuel bring.
In order to improve the prompting effect to staff, the warning device selects audible-visual annunciator；
By selecting audible-visual annunciator so that staff can be received and be carried by alarm and light two ways of warning
Show.
In order to reduce the wrong report of warning device, the lever switch is provided with time-delay relay with the circuit of warning device；
Time-delay relay is set by the circuit of lever switch and warning device, the time of fire alarming to warning device enters
Row is postponed, it is to avoid lever switch once being powered, just alarmed, coal store is effectively dredged in Rapping apparatus by warning device
Staff is still notified afterwards, increases the workload of staff.
The congestion position of coal store is observed for the ease of staff, and is easy to dredge coal store, the coal storage
Storehouse is provided with the bar hole of vertical direction.
By setting the bar hole of vertical direction on coal store, it is easy to staff to observe the position that coal cinder is put up a bridge with congestion
Put, and be easy to the staff to carry out dredging operation to coal cinder by bar hole using instrument.
