Abstract
The utility model relates to a drying grate material thickness automatic checking and adjusting device which comprises a material position sensor, a transmitting unit, a programmable logic controller, a grate bed motor transducer, a shuttle-type material distributor motor transducer and a wide belt motor transducer, and is characterized in that the material position sensor is arranged on a grate bed material layer, an output end of the material position sensor is connected with an input end of the transmitting unit, an output end of the transmitting unit is connected with an input end of the programmable logic controller, and the output end of the programmable logic controller is respectively connected with the input ends of the grate bed motor transducer, the shuttle-type material distributor motor transducer and the wide belt motor transducer. When the drying grate material thickness automatic checking and adjusting device works, the programmable logic controller combines with original set values of the drying grate material thickness to realize automatic adjustment to the speed of a drying grate, a shuttle-type material distributor motor and a wide belt motor under dynamic state according to feedback signals sent by the material position sensor through the transmitting unit. Since real time material position signals are introduced and are properly adjusted, the evenness of the material thickness on the grate bed can be guaranteed.
Description
Technical field
The utility model belongs to motor control assembly, is thick automatic detection of drying grate material and adjusting device specifically.
Background technology
In the pelletizing process production process, the green-ball of producing will pass through material distributing machine, cloth is at drying grate uniformly, be convenient to green-ball thermally equivalent on chain is combed, guarantee the gas permeability of the bed of material, guarantee the balance of temperature and wind system, green-ball is carried out drying, preheating, obtain qualified preheating pelletizing, cloth is an important step of grate kiln process system, and the uniformity of cloth is even more important, the cloth inequality can cause the heat power engineering system instability, product quality descends, and grate plate is out of shape or drops, and can cause the consequence of stopping production when serious.And prior art is because detection means is improper and do not form closed-loop control with cloth system, so the cloth uniformity is not high.Therefore design and a kind ofly can guarantee green-ball the thick automatic detection of the drying grate material of cloth on drying grate and adjusting device are very necessary equably.
Summary of the invention
The purpose of this utility model provides thick automatic detection of a kind of drying grate material and adjusting device, with guarantee to guarantee green-ball equably cloth on drying grate.
For achieving the above object, the utility model adopts following technical scheme: thick automatic detection of drying grate material and adjusting device, comprise level sensor, transducing unit, programmable logic controller (PLC), a comb bed motor frequency conversion device, shuttle-type material distributing machine motor frequency conversion device and wide belt motor frequency converter, it is characterized in that level sensor is arranged on the bed bed of material top of combing, the output of level sensor is connected with the input of transducing unit, the output of transducing unit is connected with the input of programmable logic controller (PLC), the output of programmable logic controller (PLC) respectively with the bed motor frequency conversion device of combing, the input of shuttle-type material distributing machine motor frequency conversion device and wide belt motor frequency converter is connected.
In such scheme, level sensor is a radar level gauge.
In such scheme, level sensor is a plurality of and even layout.
In such scheme, level sensor is 5.
During the utility model work, the feedback signal that programmable logic controller (PLC) is sent here through transducing unit according to level sensor in conjunction with the thick setting value of drying grate material, is dynamically directly realizing regulating automatically to drying grate, shuttle-type material distributing machine, wide belt speed down.Owing to introduced Realtime Level signal and timely adjustment, the uniformity of the bed material loading bed thickness that therefore not only guaranteed to comb also prevents the grate plate distortion or drops, and has prolonged service life of equipment, has saved cost.
