Abstract
The utility model provides a scraper machine timing constant speed control device which comprises change-over switches which are in electric connection with a motor of a scraper machine, a start button, a stop button, a contactor and a hot protective relay. The scraper machine timing speed-deciding control device is characterized in that the change-over switches, a time relay and an intermediate relay are arranged between the start button, the stop button and the contactor. Coke-scraping time and stop time of the scraper machine can be accurately controlled alternately in a timing constant speed mode, the scraper machine is enabled to finish scraping coke in a control area evenly within the fixed time, even feeding can be achieved finally, uneven stress of a belt caused by large or small transport capacity cannot happen, the situation that tail coke is reserved on the lower portion of a cooling coke table is ensured, the situation that next oven coke enters a belt conveyor without cooling to cause damage to a conveying belt to influence the serve life of the belt is prevented, safe and stable production can be conducted, in addition, enough cooling coke time and feeding time are guaranteed, coke moisture can be controlled evenly, and the scraper machine timing constant speed control device is beneficial to guaranteeing or improving coke quality.
Description
Technical field
The utility model relates to a kind of timing control device in constant speed, and especially a kind of device that blanking scraper plate machine is carried out the control of timing constant speed belongs to blanking control technology field.
Background technology
In the coking production process, whenever produce an oven coke, need to handle through the ammoniacal liquor quenching, the cool burnt platform of putting into inclination again is cool to be shone, under the state that fully volatilizees of the cool coke moisture that shines, by the scraper plate machine of cool Jiao Tai lower end, with coke equably scraping delivery to the belt transporter of the burnt platform of cold below, under the condition that guarantees the belt transporter smooth operation, be sent to the storage coke bin and store or export trade.The confidential blanking amount of controlling a plurality of feed openings simultaneously of each scraper plate.Because being subjected to on-the-spot geographic restriction, cause the material mouth size of a plurality of feed openings uneven, so when blanking, need manually the scraper plate machine ceaselessly to be carried out crawl control, and the manual operation meeting causes the inhomogeneous present situation of blanking amount, the coke at the roomy position of material mouth has descended soon, and the coke at the narrow position of material mouth is always cumulative, and it is unbalanced to cause coke to enter the overall cool solarization time of cool Jiao Tai therefrom, have a strong impact on the quality of coke, even have red coke and fall on the belt transporter and belt is burnt out.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to provide the scraper plate machine timing control device in constant speed of the balanced blanking of a kind of energy, not damage relevant device, facility, guarantees the balanced blanking of cool burnt platform, production safety is stablized carried out, and improves coke quality.
The utility model is finished by following technical proposal: a kind of scraper plate machine is control device in constant speed regularly; comprise and the dynamo-electric change-over swith that is connected of scraper plate; startup, stop button; contactless switch and hot protective relay is characterized in that arranging change-over swith, time relay and intermediate relay between startup, stop button and contactless switch.
Described change-over swith is commercial manual change-over switch and automatic transfer switch, realizes automatically and manual two kinds of operation modes.
Described time relay arranges two at least, one of them is the time relay of control scraper plate machine work-hours, another is the time relay of control scraper plate machine standing time, make scraper plate machine balanced coke of having scraped in this control area in specific time, finally realize the balanced blanking of scraper plate machine.
Described intermediate relay arranges two at least, for the fluctuation of the capacitance current, voltage and the system voltage that prevent cable.
The utility model can arrange a plurality of, alternately to control the work of a plurality of scraper plate machine.
The utlity model has following advantage and effect: adopt such scheme, the timing constant speed is alternately controlled burnt time of scraping of scraper plate machine, standing time exactly, can make scraper plate machine balanced coke of having scraped in this control area in specific time, the final balanced blanking that realizes the scraper plate machine, guarantee the balanced blanking of cool burnt platform, and then can not cause the belt operational throughput because of many, because making the belt unbalance stress less, thereby influence the problem in its service life; Can guarantee simultaneously that cool Jiao Tai bottom has Last Coke to retain, just pour on the belt transporter to stop next oven coke to shine without cold, and to the damage that travelling belt causes, make production safety, stable carrying out; Can ensure enough cool burnt time and blanking time in addition, make coke moisture obtain balanced control, be conducive to guarantee or improve coke quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The scraper plate machine that the utility model provides is control device in constant speed regularly, comprise the change-over swith 2,3 that is electrically connected with the dynamo-electric machine 1 of scraper plate, startup, stop button 5,4, contactless switch 14 and hot protective relay 13, wherein, between stop button 4 and contactless switch 13 and hot protective relay 14, change-over swith, time relay and intermediate relay are set; Described change-over swith is commercial manual change-over switch 15 and automatic transfer switch 6, to realize automatically and manual two kinds of operation modes; Described time relay arranges 10,11 2, wherein time relay 10 is used for control scraper plate machine work-hours, time relay 11 is used for control scraper plate machine standing time, the contact 19 of intermediate relay 8 links to each other with time relay 10, make scraper plate machine balanced coke of having scraped in this control area in specific time, finally realize the balanced blanking of scraper plate machine; Described intermediate relay arranges 8,12 2; the contact 18 of time relay 10 links to each other with time relay 11; be used for 11 work of control intermediate relay; the contact 17 of time relay 11 links to each other with intermediate relay 12; be used for 12 work of control intermediate relay; the delayed contact 7 of intermediate relay 11 links to each other with time relay 10; be used for the work of period relay 10; the contact 16 of intermediate relay 12 links to each other with contactless switch 14 and hot protective relay 13; 9 is zero line, and A, B, C are three alternating current wires.
During work: press self-locking start button 5, automatic transfer switch 6 starts, intermediate relay 8, contact 19 and delayed contact 7 closures, make time relay 10 electric, when reaching burnt time of scraping of setting, delayed contact 18,17 is closed successively, time relay 11 and intermediate relay 12 are got, contact 16 closures, it is electric that contactless switch 13 is got, hot protective relay 14 energisings, connect motor 1 loop, make the scraper plate machine under motor 1 drives, begin to scrape Jiao; When time relay 11 reaches burnt time of scraping of setting, delayed contact 7 disconnects, make time relay 10 dead electricity, also dead electricity thereupon of time relay 11 simultaneously, when reaching the standing time of setting, delayed contact 7 closures, time relay 10,11 gets, connect motor 1 loop again, to carry out the operation that the next one is scraped Jiao, stopped, so finishing the alternation of scraper plate machine.
