Abstract

The utility model relates to a fuel conveying controller, which comprises a fuel storehouse, a feeder and a burner. The fuel storehouse is connected with the feeder; the feeder is connected with a pipeline solid flow meter and is communicated with the burner; the pipeline solid flow meter is connected with a transmitter; the transmitter is connected with a control computer; the control computer is connected with a driving controller; the driving controller is connected with the feeder. The fuel conveying controller adopts the pipeline solid flow meter to replace a complicated metering conveying system in the background art, and the actual flow rate of materials in a pipeline can be known at any time; the utility model can be used for the control of a multiplex coal injection burner. The utility model has the advantages of simple structure and low running cost. The fuel conveying controller is an ideal automatic controller used for fuel conveyance in gas and solid phases.

Description

The fuel conveying control device
Technical field
The utility model relates to a kind of fuel conveying control device, belongs to technical field of automatic control, can be widely used in the Coal powder spray burnings such as rotary kiln, boiler of power plant in blast furnace, the cement plant of steel plant, Gu adopt the occasion of gas-two-phase transfer the fuel.
Background technology
The pipeline conveying powder material system that uses is to use belt conveyer scale, rotor scale, Coriolis scale or heavy plate flowmeter etc. earlier at present, and after the material that carry was measured, the method for being carried by the blower-use strength was carried material with air quantity and entered next link again.What of conveying capacity are controlled by feeding controlling organization (batcher) or air quantity controlling organization (air door) owing to above-mentioned measuring equipment complex structure, cost an arm and a leg, and often occur getting stuck, fault such as obstruction, he often causes mass transport to interrupt.If these faults appear in the fuel delivery system in steel mill, power plant, cement plant, can cause main process equipment to stop, stop production, cause the tremendous economic loss.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of transmission measurement system of selecting for use solid flowmeter to replace the background technology complexity in system, remove traditional weigher, simple in structure, cost is low, production efficiency is high fuel conveying control device.
The technical scheme that addresses the above problem is: a kind of fuel conveying control device, comprise feed bin, batcher, burner, and feed bin is connected with batcher.Batcher is connected with the pipeline solid flowmeter, communicates with burner; The pipeline solid flowmeter is connected with transmitter, and transmitter links to each other with controller calculation machine, and the control computer links to each other with driving governor, and driving governor is connected with batcher.
Adopt technique scheme, select the pipeline solid flowmeter for use, utilize it to measure accurately and replace transmission measurement system complicated in the background technology, utilize the dynamic measuring characteristics of pipeline solid flowmeter, understand the actual flow of material in the pipeline in real time, can be used for the control of multichannel coal powder injection burner.The result is simple for this device, and operating cost is low.It has overcome the weak link that the pipeline conveying solid substance granular material system of background technology easily breaks down, thoroughly eradicated because of the weigher fault cause blowing out, stop kiln, parking accident, production efficiency height.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
The specific embodiment
The utility model is the improvement to background technology, and its design philosophy is to replace traditional weigher with pipeline solid flowmeter 3.Overall structure such as accompanying drawing 1, its feed bin 1 is connected with batcher (control valve) 7.Batcher (control valve) 7 is connected with breeze fan 8, pipeline solid flowmeter 4, and batcher (control valve) 7 communicates with burner 5 by pipeline solid flowmeter 4.Pipeline solid flowmeter 4 is connected with burner 5.Transmitter 3 is connected with pipeline solid flowmeter 4, calculates machine 2 with controller and is connected.Controller is calculated and 2 is connected with driver 6, and driver 6 is connected with batcher (control valve) 7.
Operation principle of the present utility model:
After main frame and control system startup, controller calculation machine 2 sends the feeding capacity signal makes driver 6 drive batchers (control valve) 7 beginning feedings.Material is sent into burner 5 burnings after by pipeline solid flowmeter 4 by pressure fan 8.Pipeline solid flowmeter 4 records the solid, powdery material that flows through pipeline and feeds back to controller calculation machine 2 through transmitter 3.Controller is calculated machine 2 can adjust the output that output signal is controlled driver 6 automatically according to setting value, and then adjusts the feeding coal of batcher (control valve) 2, makes it reach the purpose of adjustment or stably feeding.Also can carry out aforesaid operations by manually utilizing controller to calculate machine 2.

Claims (1)

1, a kind of fuel conveying control device comprises feed bin, batcher, burner, and feed bin is connected with batcher, it is characterized in that, batcher is connected with pipeline solid flow machine, communicates with burner; Pipeline solid flow machine is connected with transmitter, and transmitter links to each other with controller calculation machine, and the control computer links to each other with driving governor, and driving governor is connected with batcher.
