Abstract
The utility model belongs to the technical field of electric sparks and provides an automatic ignition device of a coal combustor. The automatic ignition device of the coal combustor is characterized by comprising an ignition gun, an oil supplying device, an automatic control system and a power-driven push rod. The power-driven push rod is connected with the ignition gun through a connection assembly. Interlocking control is performed among a control circuit of the power-driven push rod, a control circuit of the ignition gun and a control circuit of the oil supplying device through a PLC. Compared with the manner of connecting a micro-air-cylinder with an ignition gun in the prior art, interlocking control is performed among all equipment circuits and automatic control of the whole ignition process is achieved, and the power-driven push rod serves as a driving device. The automatic ignition device has the advantages of being free of influences of high temperature and dust do not exist and especially suitable for the working environment of a fuel coal heat source device. Generally speaking, the automatic ignition device of the coal combustor is high in automation degree and low in stoppage rate, thus, the production efficiency is further improved and maintenance cost is reduced.
Description
Technical field
The utility model belongs to the spark technology field, particularly supporting on the coal-fired combusting device of asphalt mixing plant, for lighting a kind of automatic ignition device of fuel oil and then firing coal-dust.
Background technology
At present, China's pulverized coalapparatus used at road building business is comprised of coal-fired combusting device, coal pulverizer, conveying coal pipe, oil-firing system and several parts of control system.Wherein, the structure of oil-firing system comprises burning torch, and the fueller that coordinates igniting with burning torch, burning torch is arranged in the automatic ignition device passage of the thick coal culm passage at coal-fired combusting device center, and burning torch is connected with the minitype cylinder that can do straight reciprocating motion.During work, minitype cylinder pushes burner hearth by burning torch, with high-voltage arc, directly light from the pressure atomization light oil of fueller ejection, and the coal dust that ignites, after igniting, fueller stops oil, and minitype cylinder exits burning torch from burner hearth again, thus the ignition process of completing.The application of this oil-firing system on pulverized coalapparatus, compare early stage employing manually with the ignite behindhand type of coal dust of torch, has an ignition success rate high, dangerous low advantage.But also there is following defect, in long-term production and application, find that the burning torch that adopts cylinder to promote can not be according to the control instruction realization igniting action accurately set, cause loss of ignition, need the maintenance of stopping, trace it to its cause, the coal fuel heating source device works in the environment of high temperature and high dust, the cylinder be connected with burning torch is for a long time under this environment, there are gas in the jar volumetric expansion and irregular following, cylinder body is heated plastic deformation easily occurs, the potted component well damage gas leakage of cylinder, advance the problems such as ash, the problems referred to above all make cylinder can't maintain normal duty, the automation control system that makes original design is inconsistent with anticipation fully, need often maintenance or change cylinder, cause production efficiency to reduce, increased production cost.
The utility model content
The utility model is that the technical scheme that its technical problem of solution is taked is, designs a kind of automatic ignition device of coal-fired combusting device, and its structure comprises burning torch, fueller and automatic control system, and this automatic control system comprises PLC controller, cable; Wherein on described burning torch, be provided with an electric pushrod, this electric pushrod is connected with burning torch by coupling assembling; Described PLC controller is connected with the switch of electric pushrod, the switch of burning torch and the switch of fueller respectively by cable, and the PLC controller carries out chain control according to the instruction set to electric pushrod, burning torch and fueller.
Preferably, also comprise that described burning torch comprises positioning seat, positioning seat is located at the afterbody of burning torch, and described coupling assembling is connected on positioning seat.
Preferably, the periphery at described electric pushrod is provided with guard assembly.
Preferably, the axis of described electric pushrod is parallel with the axis of burning torch.
The utility model adopts technique scheme: an electric pushrod is connected with burning torch, and, by the chain control between circuit, can have realized the automatic ignition process of whole igniter.Secondly electric pushrod is a kind of power-jdriven gear, be not subject to the impact of high temperature and dust, be specially adapted to the hot environment that the coal fuel heating source device is worked, guaranteed in adverse circumstances the accurate control to the burning torch front-rear reciprocation movement, in sum: automation degree of equipment is high, failure rate is low, and then improved production efficiency, reduced maintenance cost.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, structure of the present utility model is further described, its structure and advantage will be clearer.
Fig. 1 is structural representation of the present utility model;
