More commonly adopt manually in the stokehold operation in the industry at present, namely manually realize break, thermometric and sampling.But whole process is meticulous loaded down with trivial details, and working strength is large, and the environment that on-the-spot high temperature, smog, molten iron splash badly is unfavorable for the operation of workman's long-time continuous especially, and the gentle security of Automated water that therefore improves the thermometric sampling system is very important.Application number is to disclose a kind of automatic temperature measurement sampling dregs breaking device in 200620098983 the patent document, comprise break rifle, temperature-measuring gun, sampling gun, firm banking, thermometric sampling lift cart, break lance lifting bogie, gun rack, break rifle drive unit, temperature-measuring gun drive unit, sampling gun drive unit, gun rack rotating driving device, can not realize comprising the automatic control of thermometric, sampling, still need manually-operated.
Summary of the invention
To the objective of the invention is in order addressing the above problem, to have proposed a kind of molten iron automatic temperature measurement sampling dregs breaking device, fully automatic program control has improved production efficiency greatly, has strengthened simultaneously the security of controlling.
The invention discloses molten iron automatic temperature measurement sampling dregs breaking device in a kind of molten iron pre-service production, increased scrambler, wireless thermodetector, frequency converter and PLC controller on the basis of original device.Wherein wireless thermodetector is installed on the thermometric sampling gun of original device, described wireless thermodetector comprises the thermometric original paper that is installed on the rifle head and the wireless launcher that is installed on the barral of a gun, the temperature data that wherein wireless launcher can wireless receiving thermometric original paper, and temperature data sent to thermometric receiving instrument and PLC controller with wireless mode, wireless transmission method is more easily realized so that apparatus structure of the present invention is simple.Scrambler is installed on the decelerating through motor arbor of break rifle drive unit, temperature-measuring gun drive unit and sampling gun drive unit of original device, is used for measuring the particular location of rifle body, the distance that is risen or descend.Three motors of frequency converter and break rifle drive unit, temperature-measuring gun drive unit and sampling gun drive unit are used for the speed of regulating electric machine respectively by electrical connection, realize the adjusting control to the rising of rifle body and decline rate; Be electrical connection between PLC controller and frequency converter, scrambler, wireless thermodetector and the motor.Requirement according to production technology, by the auto-programming of PLC controller temperature, scrambler numerical value (rifle body position data) and the predefined parameter (initial position, standby position, break position, the speed setting value that comprise rifle body) etc. next according to collection, thereby drive the motor of this device or automatic break, thermometric and the sampling process that the rifle body is realized molten iron by the control frequency converter.The application of the automation control system of introducing among the present invention has improved production efficiency greatly, thereby simultaneously owing to having replaced on-the-spot manually-operated to strengthen the security of controlling.
The invention has the advantages that:
(1) after the present invention adopts robotization control, improved the automatization level of thermometric sampling and break, thereby improved greatly production efficiency;
(2) replace manually-operated by controllable mechanical electric equipment, thereby strengthened the security that the STEELMAKING PRODUCTION scene is controlled.
Description of drawings
Fig. 1 is thermometric sampling break artwork provided by the invention.
Among the figure:
1-rifle body; 2-gun rack rotating driving device; 3-initial bit (position of attentioning); The stand-by position of 4-; 5-boosts; 6-falls after rise; 7-descends; 8-rises.
Embodiment
The present invention is described in further detail below in conjunction with artwork.
The present invention is the improvement to molten iron automatic temperature measurement sampling dregs breaking device of the prior art and method, its whole technique as shown in Figure 1, each step is temperature, scrambler numerical value and the predefined parameter (initial position, standby position, break position, the speed setting value that comprise the rifle body) etc. come according to collection by the PLC auto-programming in the course of work, thereby drives automatic break, thermometric and the sampling process that this device is realized molten iron by the control frequency converter.Concrete steps are as follows:
1, rifle body 1 is parked in the position 3 of attentioning, and is in the position of attentioning and can selects rifle or change the rifle head by the gun rack rotating driving device in 3 o'clock; Described rifle body 1 comprises break rifle, temperature-measuring gun or the sampling gun that is installed on the gun rack.
2, after hot-metal car puts in place, the gun rack rotating driving device is selected the break rifle, and the PLC controller sends instruction to the gun rack rotating driving device, and the break rifle is boosted stand-by position 4, opens simultaneously port lid;
3, the PLC controller sends instruction to break rifle drive unit, drives the break rifle and descends, and touches molten iron surface slag blanket and begins break;
4, after the break success, the break rifle rises to stand-by position 4, then falls after rise to the position 3 of attentioning, and break is finished;
