Abstract
The utility model discloses an upper felt vacuum system pipeline structure of a paper machine. The upper felt vacuum system pipeline structure comprises steam separators, downpipes, a vacuum pipeline, a water seal tank, felt, a first vacuum pump and a second vacuum pump. The upper felt vacuum system pipeline structure is characterized in that one ends of the steam separators are communicated with the downpipes, the other ends are connected with the vacuum pipeline, and the steam separators and the vacuum pipeline are provided with vacuum regulating butterfly valves; the downpipes are inserted into the water seal tank; the first vacuum pump and a second vacuum pump are communicated with the vacuum pipeline; the location difference between the steam separators and the water seal tank is 6 meters. According to the upper felt vacuum system pipeline structure of the paper machine, felt vacuum degree is increased stably, dryness of pressed sheets is improved, steam consumption is saved, and speed is increased; the vacuum degree of the upper and lower felt is not less than 0.06 MPa; the vacuum degree of the vacuum system is stable, motor load is not volatile, and meanwhile, load is lowered and white water recovery is free of overflowing.
Description
Technical field
The utility model belongs to paper making equipment, particularly a kind of paper machine squeezing top felt vacuum system pipeline configuration.
Background technology
In prior art, papermaking press portion configuration mode be the upper and lower felt of twice press with large-roll-diameter band with together with optical pressure, page enters pressure roller nip extrusion dehydration to felt by felt, after upper and lower felt outgoing nip, through the vacuum draw of suction flat box, reach and promote the clean object with mass dryness fraction of felt, thereby the clean and mass dryness fraction of felt is the principal element of page dehydration, there is certain problem in existing press section vacuum system, there is a chain of negative effect, main honorable following several respects: 1, the vacuum degree deficiency of felt up and down (vacuum≤0.04MPa) of twice squeezing.2, vacuum-load is unstable, and fluctuation of motor current is large, motor oepration at full load.3, vacuum is unstable, causes disconnected paper frequent.4, the steam-water separation effect of vacuum system is bad, and the water that felt takes off directly enters vavuum pump, causes whole vavuum pump water ring system unstable, and a large amount of plain boiled water runs off.5, by the web dryness low (≤42%) of press section, steam consumption is larger, has restricted the space that the speed of a motor vehicle promotes.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of paper machine squeezing top felt vacuum system pipeline configuration, this paper machine squeezing top felt vacuum system pipeline configuration, stable lifting felt vacuum, improve the mass dryness fraction that squeezing page, steam saving consumes, and improves the speed of a motor vehicle: the vacuum that improves upper and lower felt is not less than 0.06MPa; Vacuum system vacustat, motor load does not fluctuate, and reduces load and not overflow of white water recycle simultaneously.
The technical solution of the utility model is: a kind of paper machine squeezing top felt vacuum system pipeline configuration, comprise steam-water separator, downpipe, vacuum pipe, water seal tank, felt, the first vavuum pump, the second vavuum pump, it is characterized in that: described steam-water separator one end UNICOM downpipe, the other end connects vacuum pipe, and steam-water separator and vacuum pipe are provided with vacuum conditions butterfly valve; Described downpipe inserts water seal tank; The first vavuum pump, the second equal UNICOM of vavuum pump vacuum pipe; The dropping place of described steam-water separator and water seal tank is poor is 6 meters.
The beneficial effects of the utility model are: paper machine squeezing top felt vacuum system pipeline configuration has lower advantageous effect: 1, vacuum significantly improves, and 0.03MPa brings up to 0.06MPa; 2, former three 250KW vavuum pumps are worked simultaneously, now only use two vavuum pumps just to meet the requirement of vacuum and vavuum pump current stabilization current stabilization; 3, the plain boiled water of the water circulation system of vavuum pump no longer includes a large amount of overflow phenomenas, all by steam-water separation tank, has been recovered to smoothly in white water chest, recycles; 4, the web dryness by press section obviously improves, and has greatly saved steam, and the speed of a motor vehicle has improved 60 meters simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of paper machine squeezing of the utility model top felt vacuum system pipeline configuration
Accompanying drawing sign: 1 is that steam-water separator, 2 is that downpipe, 3 is that vacuum pipe, 4 is that water seal tank, 5 is that felt, 60 is that the first vavuum pump, 61 is the second vavuum pump
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of paper machine squeezing top felt vacuum system pipeline configuration, comprise steam-water separator 1, downpipe 2, vacuum pipe 3, water seal tank 4, felt 5, the first vavuum pump 60, the second vavuum pump 61, it is characterized in that: described steam-water separator 1 one end UNICOM downpipe 2, the other end connects vacuum pipe 3, and steam-water separator 1 is provided with vacuum conditions butterfly valve with vacuum pipe 3; Described downpipe 2 inserts water seal tank 4; The first vavuum pump 60, the second vavuum pump 61Jun UNICOM vacuum pipe 3; The dropping place of described steam-water separator 1 and water seal tank 4 is poor is 6 meters.
