Background technique
It is raw in milling train by manufacturing technique requirent as the cold mill complex of one of main unit in production technology procedures for steel rolling
Emulsion system is installed outside producing line line, because production is cooling, the needs of lubrication, and divides net liquid system and dirty liquid system, to ensure
The stable operation of milling equipment, it is very strict to dirty liquid system requirements；Existing dirty liquid system, dirty liquid are pumped cooled lubrication
Liquid is evacuated to filtering level bed, is filtered by level bed filter paper, in filter process, cannot filter when surface piles with foul
When, when the liquid level detector above filter paper detects that liquid level is excessively high, chain bed, which starts, to carry out automatic replacement filter paper and carries out next round mistake
Filter, filtered lubricating fluid flow to net liquid case, and net liquid pump is turned clean lubricating fluid to strip and roller and fastened, and provide the cold of cleaning
But liquid reaches cooling and lubrication strip, roller system purpose.Existing filtering level bed structure mainly includes organic frame, is arranged in rack
There is cabinet, the intracorporal top of case is equipped with chain bed, and the cabinets cavity below chain bed is net liquid storage chamber, and the top of cabinet is equipped with dirty liquid
Pipe, blower and chain bed driving device, cabinet lateral wall upper end are equipped with overflow pipe, and lower end is equipped with net liquid pipe, and cabinet side is equipped with filter
Paper bracket is simultaneously rolled up equipped with filter paper, and filter paper is laid with along chain bed upper surface, since the pressure-pad-force of both sides stripper rubber is inconsistent, leads to two
Side filter paper and stripper rubber frictional force size are uneven, and filter paper is filtered due to the weight effect by dirty liquid in filter process
The edge of paper also can be to middle shrinkage, so that fold occurs in filter paper edge, and a large amount of particulate matter in dirty emulsion is from filter paper side
It is filtered at portion's fold just to enter the lubricating fluid that pollution is clean in the net liquid storage chamber below filter paper, cause belt steel surface to be formed
Roll marks；Due to filter paper edge leakage, make effectively establish liquid level above filter paper, so filter paper can not normal automatic carriage, lead
Filter paper poor filtration effect is caused, therefore roll marks roll change daily, up to 3 times, seriously constrain milling train rolls the surface quality rolled up firmly, steel rolling
Yield performance does not come out, while but also roller consumption is high.
Summary of the invention
The purpose of the present invention is to emulsion of rolling mill filtering level bed filter paper edge during filter operation pleat occurs
It wrinkles this problem, a kind of simple and practical, easy to adjust, filter paper using effect more preferably synchronous pressure roll-type filter bed device is provided.
Concrete scheme of the invention is：A kind of synchronous pressure roll-type filter bed device has rack, is disposed with cabinet in rack,

And chain bed driving device, the upper and lower part of cabinet lateral wall are respectively equipped with overflow pipe and net liquid pipe, the front end of cabinet is equipped with filter
Paper bracket is fitted with filter paper on paper filter support, and filter paper is laid with along chain bed upper surface, is located at filter paper two sides along each in cabinet wall
Equipped with a sealing flange fixing installation, it is additionally provided with liquid level detection device above the sealing flange fixing installation on cabinet wall, after cabinet
End is equipped with filter paper and exports roller, and the top positioned at the filter paper export roller in filter paper exit is equipped with filter paper synchronous-roller on the rack
Device, the filter paper synchronous-roller device include the compression roller adjusting device being symmetrically installed on the rack and are arranged in two pressure roller tune
Synchronous-roller between engagement positions.
Heretofore described compression roller adjusting device has the pressure roller mounting plate being vertically arranged, the pressure roller mounting plate and rack
It is fastenedly connected, being coaxially welded on pressure roller mounting plate has top nut and lower nut, is respectively threaded with one in top nut and lower nut
A adjustment hold-down bolt, two adjust between hold-down bolts for compressing the roll shaft of fastening synchronous-roller；In top nut and lower spiral shell
A rectangle roll shaft limiting slot is offered on pressure roller mounting plate between mother, the rectangle roll shaft limiting slot is for placing synchronous-roller
Roll shaft.
The present invention solves on existing level bed caused by filter paper sealing pressure at both sides is inconsistent and both sides filter paper asynchronism
Filter paper fold, and then lead to emulsion, lubricating fluid etc. dirty liquids filter effect is bad, finally make rolled band steel quality occur and lacks
The problems such as falling into, such as generating roll marks, roller bubble；And a synchronous-roller is arranged by exporting in filter paper in the present invention above roller, lead to
It crosses synchronous-roller and compression appropriate is carried out to the filter paper on filter paper export roller, be that friction connects between synchronous-roller and filter paper at this time
Touching, the presence of synchronous-roller make the pressure of the two sides of filter paper more balanced, and the tensioning of whole filter paper is more preferable, passes through worker's
Practical operation discovery, is arranged after synchronous-roller, has prevented the generation of dirty liquid leakage, filter paper buckling phenomena substantially；Pass through simultaneously
The case where synchronous-roller, which is arranged, realizes the equilibrium of filter paper pressure at both sides, thus can be by thicker filter paper is only used originally（It is thick
Although the good still slow low efficiency of the rate of filtration of filter paper filter effect, the filter paper the thin more is easy to appear fold, while thick filter paper cost
It is high many）It is substituted for using relatively thin filter paper, can equally reach good effect, and filter paper is at low cost, and be not in pleat
Wrinkle.
Compression roller adjusting device in the present invention can adjust the height of synchronous-roller according to different filter paper thickness
It is whole（The roll shaft that hold-down bolt compresses synchronous-roller is adjusted by two, roller of synchronous-roller itself can rotate）, because not
The filter paper of stack pile, synchronous-roller are also different its pressing force, are just able to achieve preferable synchronous compression effect in this way.
The present invention can reduce oil consumption indirectly, realize the mutual conversion of thick, thin filter paper and filter paper will not all be made to generate fold, drop
Low production cost is overhauled, is safeguarded, adjusting simple and convenient, and equipment is durable.
