The situation of head happens occasionally, and general control strategy can not get around failure and cut somebody's hair when blocking tripping when cutting somebody's hair, therefore event of cutting somebody's hair
During barrier, by tripping so as to reduce blowing amount, taking turn continues this result until fault restoration of cutting somebody's hair is complete after complete one week for this operation
Into so as to increase fault rate, maintenance rate, reduce blowing efficiency.
Utility model content
The purpose of this utility model be directed to prior art presence problem provide one kind can automatic detection thus blowing barrier
Cut somebody's hair and blowing can be adjusted and cut somebody's hair the rotary kiln charging system of blowing strategy.
Concrete technical scheme of the present utility model is as follows：
A kind of rotary kiln charging system, including rotary kiln, preheater feed bin, blowing belt and Hydraulic Station, the blowing skin
Band discharge end is corresponding with preheater feed bin charging aperture, and preheater feed bin discharge hole is connected with rotary kiln kiln tail, and preheater feed bin goes out
It is provided with multigroup circulation blowing hydraulic pressure at material mouth to cut somebody's hair, multigroup circulation blowing hydraulic pressure is cut somebody's hair and be connected with Hydraulic Station；Also include
Position switch, PLC control system, PC, the position switch are arranged on multigroup circulation blowing hydraulic pressure cuts somebody's hair, and position opens
Connection is connected to PLC control system, and the PLC control system is connected with PC and Hydraulic Station electric cabinet respectively；
The preheater feed bin middle part is provided with radial gravity sensor, and the radial gravity sensor is connected to PLC
Control system, the PLC control system is by frequency converter and the motor connection of blowing belt；
Belted electronic balance is provided with the blowing belt, the belted electronic balance is connected to PLC control system, the PLC
Control system is by frequency converter and the motor connection of blowing belt.
The utility model has the advantages that：
The utility model is cut somebody's hair to multigroup failure circulated during blowing hydraulic pressure is cut somebody's hair by position switch and is detected and incited somebody to action
Information transfer to PLC control system, by after the information gathering and analysis of PC, by failure cut somebody's hair information it is placed within therefore
Staff is reminded in barrier database, meanwhile, PLC control system adjustment Hydraulic Station control strategy, in multigroup circulation blowing hydraulic pressure
Cut somebody's hair it is next circulation blowing when, skip the failure and cut somebody's hair, reduce system servicing down times, reduce equipment maintenance, collection
In trouble point is processed, it is ensured that the uninterrupted accurate operation of production；Radial gravity sensor can detect preheater
Weight of material in feed bin, and in the case where material is excessive or very few, blowing belt blowing speed is controlled by PLC control system
Degree, belted electronic balance can detect the weight of material on blowing belt, further enhance the blowing accuracy of blowing belt.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is electrical apparatus control system connection figure of the present utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of rotary kiln charging system, including rotary kiln 1, preheater feed bin 2, the and of blowing belt 3
Hydraulic Station 4, the discharge end of blowing belt 3 is corresponding with the charging aperture of preheater feed bin 2, the discharging opening of preheater feed bin 2 and rotary kiln 1
Kiln tail is connected, and the discharge outlet of preheater feed bin 2 is provided with multigroup circulation blowing hydraulic pressure and cuts somebody's hair 5, multigroup circulation blowing hydraulic pressure
Cut somebody's hair and 5 be connected with Hydraulic Station 4；Also include position switch 6, PLC control system 7, PC 8, the position switch 6 is arranged at multigroup
Circulation blowing hydraulic pressure is cut somebody's hair on 5, and position switch 6 is connected to PLC control system 7, the PLC control system 7 respectively with PC
