A kind of big flow vacuum apparatus described in the utility model, comprise casing, be located at casing middle part the chain bed, be layered on filter paper on the chain bed, be positioned at former liquid pool on the chain bed, the negative pressure chamber under being positioned at, be located at casing one end be connected with the chain bed cooperation chain bed driving mechanism, the electrical contact switch cabinet that is located at casing one side and switch board, be located at the support of bottom half, it is characterized in that: be provided with vavuum pump on casing, the inlet tube of vavuum pump stretches in the negative pressure chamber, outlet is corresponding with air distributor above being located at former liquid pool; On former liquid pool, be provided with more than one stoste distributor and corresponding with it stoste enters pipe; Be provided with clean liquid pipe and liquid back pipe in the bottom of casing; Clean liquid pipe communicates with clean liquid case, and liquid back pipe communicates with the stoste case.
Described a kind of big flow vacuum apparatus is characterized in that: be provided with sealing strip and sealing clamp and hold-down bolt on the both sides of chain bed, be provided with carrying roller below the chain bed.
Described a kind of big flow vacuum apparatus, its clean liquid case (22) and stoste case (23) connect as one, and the height of dividing plate is lower than the height of sidewall between the two, and the volume of stoste case is greater than the volume of clean liquid case.When milling train quit work, the emulsion filter pump did not quit work.The emulsion of clean liquid case overflows to the stoste case, thereby realizes continuous filtration, circulating filtration and filtration fully.
Described a kind of big flow vacuum apparatus is provided with overflow launder on the next door of former liquid pool, is provided with float switch in former liquid pool, and float switch links to each other with switch board.
Characteristics of the present utility model are: whole box body is Welding Structure, and is simple in structure, simple for production, reliable owing to adopt liquid level control and vacuum degree control, once change paper for a long time fault-free move continuously; Filter capacity is strong, and filtration yield reaches 13000L/min; A filtering accuracy height, controlled within the specific limits characteristics.
The utility model is compared with prior art and had the following advantages: filter capacity is big, can realize that 13000L/min filters, and the filter capacity that level bed or leaf filter are generally has only 3000～5000L/min; The high and low pressure contact of filter paper walking employing is control and liquid level ball float control model automatically, realizes continuous filtration, need not stop when changing filter paper, does not influence the continuous filtration of emulsion and filtration fully; This filter filtering accuracy can select the filter paper of different accuracy to realize with the different negative pressure value of setting according to customer requirements.Because this filter is to realize that by the Negative Pressure Difference between vacuum chamber and the atmospheric pressure low-pressure filters, and compares with leaf filter with traditional level bed filter, almost is zero failure, does not have the maintenance operation, use cost is low.Can satisfy that aluminium hot rolling tandem mill is confidential asks the continuously big flow of hole liquid, high-precision filtration requirement.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, at first, open the power switch on the electrical contact switch cabinet 7 of casing 18 1 sides, start chain bed driving mechanism 1, chain bed 6 promptly is being with filter paper 13 to move between carrying roller 17 and sealing strip 16, finishes the laying of filter paper to the paper delivery end from going into the paper end.The sealing strip sealing that the both sides of chain bed are passed through, sealing strip and sealing clamp 15 are close to, and sealing clamp is fixing by hold-down bolt 14,
Restart stoste delivery pump 24, with the stoste (emulsion before promptly filtering) in the stoste case 23 below the support 21 in stoste enters the pipe 20 stoste distributors of delivering on the former liquid pool 11 5, the effect of stoste distributor is that the stoste of band pressure is slowed down, make it evenly, slowly and enter former liquid pool glibly, avoid stoste with pressure directly to be punched on the filter paper filter paper is washed out.
Simultaneously, start the air that vavuum pump 2 is discharged in the negative pressure chamber 19,3 pairs of the outlet of vavuum pump and the air distributors above the former liquid pool should make the pressure reduction between negative pressure chamber's formation and the atmospheric pressure.Stoste enters negative pressure chamber by filter paper under the effect of pressure reduction and deadweight.
During stoste process filter paper, wherein aluminium bits and other booty are stayed on the filter paper.Along with the carrying out of filtering, sludge constantly thickens on filter paper, and sludge forms a cake layer on filter paper, it in filtration subsequently as the filtering material filtration.Along with constantly thickening of cake layer, more tiny particle also is left on the filter paper, and filtering accuracy further improves, and this filtration is cake filtration, and cake filtration need be absolutely necessary in the system than high filtering precision.Emulsion after the filtration is called clean liquid, enters clean liquid case 22 through clean liquid pipe 9, and clean liquid pump 25 is transported to hot-rolling mill 26 with clean liquid and uses, and the cooling-lubricant after hot-rolling mill is used flows into stoste case 23 through blow-off pipe 27.
When cake layer reached certain thickness, by the former liquid measure minimizing of filter paper, the negative pressure value in the negative pressure chamber increased gradually, and stoste increases by the resistance of filter paper, and former liquid pool liquid level raises.When the liquid level of former liquid pool reached setting value, stoste promptly flow back into the stoste case from overflow launder 10, and float switch 4 actions that link to each other with switch board 8 make chain bed driving mechanism out of service.
Also can set the negative pressure value in the negative pressure chamber, when reaching setting value, chain bed driving mechanism realizes walking automatically, stopping filter paper under the control system effect.
At the arrival end of former liquid pool, because of not forming filter cake, make that negative pressure value is low in the negative pressure chamber on the filter paper of this part, big by the former liquid measure of filter paper.This part filtration zone is overlaying the district, and the stoste that overlays district's filtration is poor because of cleannes, is flow back to stoste case 23 through liquid back pipe 12.
Owing to have pressure reduction between negative pressure chamber and the atmospheric pressure, the pipeline that links to each other with negative pressure chamber must go deep into the case bottom, to keep the seal of negative pressure chamber.Simultaneously, because of there being negative pressure in the negative pressure chamber, the difference in height of the high liquid level (HLL) of former liquid pool bottom and casing must be more than 3000mm, so that the water-column that produces because of pressure reduction to be provided.
This device can be used for the emulsion of heat, cold aluminium milling equipment and filters, and is used for being separated in the mineral wet goods that aluminium powder, greasy dirt, booty and emulsion in the emulsion self decompose out that remains in that produces in the operation of rolling, and the emulsion of cleaning is provided for milling train.
