Abstract
The utility model discloses a fire coal multilevel conveying device which comprises conveyors and a control device. The fire coal multilevel conveying device is formed by more than one conveyor in a built-up connection mode in series or in parallel. Each conveyor is provided with an online pressure sensor, a driving motor and a frequency conversion controller, and the conveyors are controlled by a PLC in a linkage mode. The conveying mode of each conveyor is one of a differential motion drum mode, a tipping bucket mode and a belt mode. Multiple levels of the conveyors are controlled in the linkage mode in the fire coal conveying process, after one or more conveyors break down, the anteposition conveyor stops conveying, the retroposition conveyor is also stopped after fire coal is conveyed, and the phenomenon of fire coal accumulation is avoided. Frequency converters arranged on the conveyors achieve the effects of regulation of fire coal conveying flow and protection of the motors.

The utility model content
For the drawback that above-mentioned traditional approach transporting buring coal exists, the utility model is intended to propose the multistage feedway of a kind of fire coal.
The technical scheme that its technical matters that solves the utility model adopts is:
The multistage feedway of a kind of fire coal, comprise conveyer and control setup, described multistage feedway is an above conveyer through the series and parallel formation that is connected, be respectively arranged with online pressure sensor, driving motor, frequency-variable controller on every conveyer, between each conveyer by PLC controller connecting move control.
Every conveyer all arranges field operation box in this feedway, and hand starting button, stop button, run signal lamp, scram button are arranged in the case.
This conveyer is equipped with overload protection and protective switch of the short circuit.
The mode of movement of this conveyer is a kind of of differential drum-type, tipping bucket type and belt-type.
The control setup of this conveyer comprises electronic scales treasure, speed sensor, electromagnetic valve, PLC controller and signal transmitting apparatus.
The electronic scales treasure is floor type or online.
Transmission mode in the signal transmitting apparatus is wire transmission or transmission over radio.
The utility model beneficial effect is: the connecting move control by for conveyer transporting buring coal at different levels the time, after one or more conveyer breaks down therein, its anteposition conveyer stops to carry, and rear position conveyer stops after complete fire coal is carried, and avoids the appearance of coal-fired packing phenomenon.The frequency converter that arranges on the conveyer plays the effect of regulating transporting buring coal flow and protection motor.
