Description
Technical field
The present invention relates to a kind of coke oven door intelligence to go out cigarette car, belong to coking production equipment technical field.
Background technology
In coking production, coke oven door poorly sealed close be one of primary pollution source of coke oven; Coking chamber can cause the raw gas in coking chamber to escape at barotropic state, affects the recovery of coke-oven gas and chemical products, and meanwhile, raw gas escapes can degradation manipulation environment, burns out furnace retaining ironware, causes coking furnace shaft to be easy to damage, and shortens body of heater work-ing life; In coking latter stage because of reasons such as collecting main pressure fluctuations, the air coking chamber that can bleed makes the graphite subject to severe risks of damage of furnace wall brickwork joint, causes the mutual blowby of furnace wall, burns part of coke simultaneously, increase ash content in coke, reduce coke quality and output; Therefore, coke oven door sealing situation with smolder, burn with anger and firedoor frame, furnace stay distortion, losing efficacy has substantial connection.During current most of coke-oven plants coke oven is produced, pushing machine and coke guide should complete production task, also to go out cigarette by manually utilizing the mode of refractory gun shutoff to carry out shutoff to coke oven door simultaneously, often because to produce and the cigarette that goes out intersects the problem causing rhythm of coming out of the stove to affect cigarette of producing or go out slowly to pollute not in time, and artificial shutoff labour intensity is larger, and poison gas can be made to damage human body, production safety coefficient is lower.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coke oven door intelligence and goes out cigarette car, this invention is without the need to manual operation, automatic, the tight shutoff to coke oven door can be realized while pushing machine and coke guide normally run, effectively stop the problem of environmental pollution because oven door sealing does not sternly cause, improve production safety coefficient and efficiency.
The technical scheme solved the problems of the technologies described above is:
Coke oven door intelligence is gone out cigarette car, and it comprises spraying system, grating positioning system, traveling brake system and circuit control system; The slurry conduit that spraying system is connected slush pump and whitewashing plate respectively by mud tank, the slush pump being located at mud tank inside, the hollow spray pulpboard and switch box, the two ends that are individually fixed in the relative both sides of mud tank outer wall is formed, size and the coke oven door of whitewashing plate are measure-alike, plate plate face is provided with swivel in whitewashing, and slush pump is electrically connected with switch box; Grating positioning system by upper end be fixed on switch box outer side wall support, be fixed on pedestal lower end moving grating scale and be fixed on fixed grating scale coke oven regenerator outer furnace wall docking signal with moving grating scale and form, moving grating scale vertical center line is positioned on the profile perpendicular to whitewashing board plane done along whitewashing plate vertical center line, moving grating scale and switch box electrical connection; Traveling brake system by the drive sprocket axle be fixed on bottom mud tank, the travelling wheel being installed on drive sprocket axle two ends, step-down gear input shaft, the step-down gear be installed on drive sprocket axle and step-down gear input shaft, the running motor be installed on step-down gear input shaft, be installed on the band-type brake of step-down gear input shaft one end and the band-type brake motor for controlling band-type brake work is formed; Running motor, band-type brake motor and switch box are electrically connected; Circuit control system comprises traveling master loop, whitewashing master loop and control loop; Traveling master loop by running motor, contactor FC1 normally opened contact, be parallel to band-type brake motor in traveling master loop and contactor FC3 normally opened contact is formed; Whitewashing master loop is made up of slush pump motor and contactor FC2 normally opened contact; Control loop is by contactor FC1 and control contact, contactor FC2 and control contact, contactor FC3, time relay KM and control contact, intermediate relay KA1 and control contact and intermediate relay KA2 and control contact to form; Traveling master loop is connected in parallel with whitewashing master loop, controls by circuit breaker Q F is unified.
Above-mentioned coke oven door intelligence is gone out cigarette car, and the distance between the travelling wheel being installed on drive sprocket axle two ends in described traveling brake system is equal with the distance between coke oven coke side platform track.
Above-mentioned coke oven door intelligence is gone out cigarette car, and described mud tank top is provided with top traveling wheel, and the direction of travel of top traveling wheel is consistent with the travelling wheel direction of travel on drive sprocket axle bottom mud tank.
Working process of the present invention is: when using at coke oven machine side, due to coke oven machine side platform rail-free, in order to ensure to go out cigarette car at pusher side platform straight-line travelling, below pusher side furnace stay, set up the slideway of I-beam as the cigarette car mud tank top traveling wheel that goes out in the mode of gusset welding, to be gone out cigarette car straight-line travelling on coke oven machine side platform by traveling wheel straight-line travelling and then guarantee on I-beam; When using at coke oven coke side, because coke oven coke side platform has track, the travelling wheel of cigarette car mud tank bottom of going out can ensure along rail running the straight-line travelling of cigarette car at coke oven coke side platform that go out.Go out in cigarette car driving process, when after moving grating scale with the initial contraposition of fixed grating scale signal of locating for coke vehicle, intermediate relay KA2 coil obtains electric, its normally closed contact is opened, traveling contactor FC1 coil, band-type brake contactor FC3 coil losing electricity, running motor quits work, band-type brake locking step-down gear input shaft, the cigarette car that goes out stops mobile, because moving grating scale vertical center line is positioned on the profile perpendicular to whitewashing board plane done along whitewashing plate vertical center line, so now whitewash, plate is just to coke oven door position, because now traveling contactor FC1 normally closed contact closed whitewashing contactor FC2 coil obtains electric, start and to utilize after slush pump whitewashing plate to carry out whitewashing to go out cigarette, whitewashing process adopts time relay KM to carry out timing (timing duration is set to 3min), slush pump motor dead electricity after whitewashing 3min, slush pump quits work, time relay KM normally closed contact is opened simultaneously, intermediate relay KA2 dead electricity, KA2 normally closed contact closes again, because the normally closed contact of FC2 is now closed, traveling contactor FC1 coil, band-type brake contactless coil FC3 respectively electric, traveling band-type brake motor obtains electric rear band-type brake and unclamps, running motor starts, the cigarette car that goes out enters the coke oven number of next cigarette that needs to go out according to grating positioning system.
Beneficial effect of the present invention is:
The present invention utilizes the feedback signal of grating positioning, under operatorless state, shutoff is carried out to coke oven door to go out cigarette by the intelligent control cigarette car that realizes going out, realize automatic, the tight shutoff to coke oven door, effectively stop the problem of environmental pollution because oven door sealing does not sternly cause, improve production safety coefficient and efficiency; Structure of the present invention is simple, easy to use, while saving manpower, ensure that the normal operation that coking is produced.
