Description
Technical field
The utility model relates to metallurgical technology/cold-rolling mill production technology, relates in particular to a kind of Emulsified liquid nozzle state device for fast detecting.
Background technology
Cold rolling unit need be used emulsion as the technological lubrication medium when producing, to reduce the effect of being out of shape heat and playing control panel shape.Emulsified liquid nozzle arrangement form at present commonly used is arranged for the spray beam, with the roll parallel direction, arranges some spray beams, sprays on beam according to the some nozzles of certain pitch arrangement.
In order to guarantee to reach corresponding process requirements, in the shutdown maintenance process of tandem mills, need to detect each nozzle and whether stop up.The main method of current cold rolling unit Emulsified liquid nozzle state-detection is that nozzle is pulled down one by one and manually checked whether nozzle stops up, though the method can be confirmed condition of nozzles, but due to hundreds of the Emulsified liquid nozzles of all having an appointment in each frame, for 5 common frame cold-rolling mills, the whole piece milling train approximately has nearly thousand nozzles, so the method inefficiency.And if, under the emulsion system opening, owing on a spray beam, numerous nozzles being arranged, and the scattering surface of each nozzle is larger, therefore in frame, mist of oil fills the air, by naked eyes, can't confirm condition of nozzles, therefore it is as follows to sum up the difficult point of current Emulsified liquid nozzle state-detection:
1, under spray beam opening, after the scattering of frame internal emulsification liquid, formed mist of oil drop fills the air, and can't confirm condition of nozzles by naked eyes.
2, the artificial method inefficiency that dismounting detects one by one, and cost of labor is very large.
Chinese Patent Application No. CN201010617450.7 discloses " cold rolling unit spray cooling device nozzle fault detection method ", the novel loop of application comprises flowmeter, stop valve and related accessories etc., element is arranged on the spray cooling spray beam on the emulsion pipeline, by control, realizes duty flow detection and nozzle inspecting state flow detection.The duty of final each spray cooling nozzle of reflection.The utility model reduces nozzle repair time and workload, can avoid artificial the detection to produce mistake, can detect the working flow of each nozzle.
Contrast: this patent is, at the inlet end of each nozzle, the related elements such as flowmeter, stop valve are installed, by the monitor and detection condition of nozzles to flow valve.But this patent is only for the outlet spray cooling nozzle of cold-rolling mill, if will extend to all nozzles in frame, cost is excessive and efficiency is too low, and practicality is not high.
The liquid ejection apparatus that a kind of inspection precision while making no liquid from the inspection of nozzle opening ejection that discloses Chinese Patent Application No. CN200910166831.5 improves, and discharge inspection method.For discharge inspection method, for spray the nozzle formation face of the record-header of ink from nozzle opening under the driving of piezoelectric element, the arranged opposite cover, between the nozzle plate of record-header and cover, be applied under the state of voltage, nozzle plate when detection sprays ink from from nozzle opening to cover and the electric variation between cover, check and have or not ink to spray from nozzle opening thus, in this discharge inspection method, use ejection that shape is different with common driving pulse (P) for inspection driving pulse (Pt) sprayed check processing, check the waveform with driving pulse according to environment temperature correction ejection.
Contrast: the method mainly is used in the detection exact instrument and whether sprays ink, with previously described problem, compares, and the method is not suitable for the operating mode of the large production of steel industry and the problem of the required solution of this patent.

Embodiment
Referring to Fig. 1, a kind of Emulsified liquid nozzle state device for fast detecting of the present utility model, it comprises, some nozzle casings 1, size coupling Emulsified liquid nozzle 100; Some injection supervisors 2, the one end is connected respectively in above-mentioned each nozzle casing 1, sprays supervisor's 2 opposite sides and upwards bends and extend; Each injection supervisor 2 is arranged side by side, and interconnects by connecting link 3; Spray supervisor's 2 other end sealings; Some playpipes 4, one end is connected in and sprays supervisor 2 side that upwards bending is extended, and be arranged in parallel along spraying the supervisor 2 side short transverse that upwards bending is extended, form at least two rows, be bottom-up first, second row's playpipe 41,42 that is arranged in parallel, first row playpipe 41 center lines are higher than the center line of Emulsified liquid nozzle 100; And the length of first row playpipe 41 is greater than the length of second row playpipe 42; Described playpipe 41 (first playpipe 41 of take is example, lower same) is offered PH test paper draw-in groove 411 and corresponding PH test paper near the upper surface, end of its liquid outlet.
Referring to Fig. 2, further, the described second row playpipe 42 tops also parallel length that is provided with the 3rd row's playpipe 43, the three row's playpipes 43 are less than the length of second row playpipe 42.
Again, each to arrange between playpipe 41～43 perpendicular separation H distance be 5～8cm.
On described injection supervisor 2 one side direction, bending is extended and is become α angle=50 °～75 ° with vertical direction.
The liquid outlet horizontal axis spacing L of described the first～three row's playpipe 41～43 remains on 10～13cm.
In addition, the ratio that 2 internal diameters square and Emulsified liquid nozzle 100 internal diameters square are responsible in injection described in the utility model is in (12～15): between 10.
During detection, nozzle casing is enclosed within on Emulsified liquid nozzle, according to emulsion system pressure condition demand, uses a certain amount of fastening bolt to carry out fastening to prevent that high-pressure emulsion from making the device displacement.
Spray supervisor's caliber and made according to the Emulsified liquid nozzle caliber, so that emulsion can pass through system smoothly, the ratio of its internal diameter square and Emulsified liquid nozzle internal diameter square is 12: 10.Simultaneously, spray supervisor's internal diameter square and be 12: 4 with the internal diameter duplicate ratio of three liquid outlets, the bent angle that sprays supervisor is 75 °.Each liquid outlet end PH test paper draw-in groove inserts high precision pH value test paper.
Open emulsion system, flow starts adjusting from minimum flow and is enlarged to gradually maximum, one minute approximately consuming time of adjustment process.The spray beam is opened after 3 minutes and is closed, and checks the state of high precision PH test paper in each liquid outlet end PH test paper draw-in groove.3 liquid outlet end test paper all do not show light yellow (in the present embodiment, the emulsion pH value is between 5.5 to 6.0, therefore be light yellow, for different emulsion of rolling mill systems, only need carry out the color judgement according to the actual pH value of unit emulsion system gets final product), explanation is flow through without emulsion, and nozzle stops up fully.
First, second row's playpipe 41,42 liquid outlet end test paper show light yellow, and the 3rd row's playpipe 43 liquid outlet end test paper do not show light yellow, and the condition of nozzles normal is described, actual flow is being set flow more than 1/3rd and below 2/3rds.
