Row.Feeder motor driving conveying belt is run, and the broken transport of materials of plaster block to conveyer belt discharging end is fallen into blanking funnel
In, the exhaust gas generated in the process is collected through case, and when dust concentration reaches certain value, sensor of dust concentration passes through signal
Signal wire is transmitted to controller；For controller by the way that line traffic control frequency conversion exhaust blower is controlled to run, dust enters bag-type dust from blast pipe
After device dedusting, discharged by frequency conversion exhaust blower.Aspiration pressure sensor, outlet air pressure sensor will be measured into and out of bag-type dust
The air pressure signal of device is transmitted to controller, filters atmospheric pressure value to subtract out the air pressure of bag filter into the atmospheric pressure value of bag filter
Value, when having served as filter atmospheric pressure value more than certain value, the rotating speed increase of controller control frequency conversion exhaust blower；It has served as filter atmospheric pressure value and has been less than one
During definite value, the rotating speed of controller control frequency conversion exhaust blower reduces；So as to ensure that controller controls the rotating speed of frequency conversion exhaust blower
System ensures to transmit the normal operation of the dust-extraction unit of blanking after crushing for plaster block.
After the completion of work, stop button is pressed, signal is passed to controller, controller control feeder motor by stop button
It is out of service with frequency conversion exhaust blower.
The beneficial effects of the utility model：
1. the utility model is simple in structure, it is easy to operate, reduce energy consumption, safe operation.
2. the utility model uses sensor of dust concentration and controller, realize and generated when plaster block transmits blanking after crushing
During dust, automatic running wind turbine has saved energy consumption.
3. the utility model using bag filter, frequency conversion exhaust blower, aspiration pressure sensor, outlet air pressure sensor and
Controller makes filter pressure be maintained at a certain range, and cloth bag is kept not block, and adjusts frequency conversion exhaust blower rotating speed on demand, saves
Energy consumption ensures safe operation.
4. the utility model signal wire and control line have higher transmission rate and good anti-electromagnetism using shielding line
Interference performance ensure that the safe operation for compressing operation.
5. the utility model controller can carry out each equipment automation control for DCS hosts, control accuracy is high.
