Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
A kind of cold rolling reversable mill as shown in Figure 1 to Figure 3 without water clock stripper device, including upper stripper 24,
It is sprayed under spray beam 4, roll gap and the body of roll on spray beam 7, roll gap and the body of roll under spray beam 6, plate face on lower stripper 22, plate face
Beam 2, the no water clock stripper device further include strip upper and lower surface edge purge nozzle 23, strip upper and lower surface at roll gap
Beam 19, spray beam movement sealing plate 20 in plate face, spray beam sealing plate mobile cylinder 26 in plate face are purged, upper spray beam negative pressure is taken out
Inhale recovery system.
At the roll gap strip upper and lower surface edge purge nozzle 23 be set to the upper stripper 24 and under anti-tangle lead
At the front end shovel head of plate 22 (namely at rolling centerline), one or more groups of, every group of two nozzles can be set according to bandwidth
It is arranged in strip both sides of the edge up and down.When passage switches, after emulsion injection in side stops, opening the side mode of blowing and prevent the other side
Roll gap gap of the emulsion of ejection other than strip width range is scurried out, and strip lower surface side blows and sprays mouth purging pressure and wants small
Mouth is blowed and sprayed in upper surface side, prevents strip lower surface from being splashed, in case the interference of upper and lower surface purge stream causes turbulent flow to be made
At splashes.
The strip upper and lower surface purging beam 19 is set to the rear portion of the upper stripper 24 and lower stripper 22, leans on
Nearly strip upper and lower surface, strip upper and lower surface purge interval on beam 19 and install a certain number of fan nozzles covering whole bandwidths.
When passage switches, after emulsion injection in side stops, opening strip upper and lower surface purging beam 19 and blow off plate face is emulsion remained
After can stop.
Spray beam movement sealing plate 20 is arranged inside upper stripper 24 in the plate face, in plate face after spray beam 6
Lower section is driven using spray beam sealing plate mobile cylinder 26 in plate face.When passage switches, spray beam 6 stops spray in the plate face of side
After penetrating emulsion, spray beam movement sealing plate 20 will be in plate face in spray beam sealing plate mobile cylinder 26 i.e. promotion plate face in plate face
The nozzle spray-hole of 6 lower part of spray beam connection covers.Spray beam movement sealing plate 20 is equipped with sealing ring in the plate face, works as plate
It can guarantee spray-hole without water clock when spray beam movement sealing plate 20 covers spray-hole on face.
The upper spray beam negative-pressure ward recovery system is cut by spray beam in spray beam stop valve 3 on roll gap, the body of roll, plate face
Disconnected valve 8, roll gap, spray beam suction valve 5 on the body of roll, spray beam suction valve 10, vacuum pump 13, gas-liquid separator 16, gas in plate face
Liquid/gas separator overflow valve 17 and drain valve 15 etc. form.When passage switches, after emulsion injection in side stops, spray beam control is closed
It is also switched off spray beam stop valve 3 and 8 while valve 1 and 9 processed, makes spray beam pipeline disconnection up and down, is remained in lower spray beam pipeline
Emulsion is then turned on vacuum pump 13 and spray beam suction because dead weight can be wandered from lower spray beam nozzle in milling train catch tray
Valve 5 and 10 aspirates upper spray beam pipeline, and remaining emulsion in upper spray beam pipeline is extracted into gas-liquid separator 16
In, emulsified liquid collection case 18 can be flowed back to by overflow port 17 after the emulsion for having accumulated certain liquid level in gas-liquid separator 16,
If storing emulsion in gas-liquid separator 16 reaches superelevation liquid level, drain valve 15 will be opened, emulsion is flow back into emulsified liquid collection case
18。
A kind of cold rolling reversable mill passes through closure upper stripper 24 upper face injection without water clock stripper device
The spray-hole of beam 6 and the spray beam pipeline being arranged on upper stripper 24 is aspirated, has fundamentally prevented switching road
Each emulsion of strip upper surface drips source when secondary, and is only opened with row's strip upper and lower surface purging beam 19 when switching passage
The a bit of time（Generally a few minutes, preferably live practical application is 3 ~ 5 minutes）Blow plate face residual breast when passage is shut down off
Change liquid, and coordinating strip upper and lower surface side to blow and spray mouth 23 can make plate face reach good cleaning effect.
Above example is only for illustration of the utility model rather than limitations of the present invention, related technical field
Technical staff can also make various transformation or modification in the case where not departing from the spirit and scope of the utility model, because
This all equivalent technical solution, both falls within the scope of protection of the utility model.
