Abstract
The utility model relates to an exhaust for a cylinder mould of a cylinder machine, which is characterized in that both ends of the cylinder mould are closed, a closing plate of the driving side is provided with a hole to mount a connecting pipe, and a fan for vacuumization is then mounted on the other end of the connecting pipe. The exhaust has the advantages that by mounting the exhaust fan, the difference between the pressure inside the cylinder mould and the pressure outside the cylinder mould can be increased, moreover, the dehydration level of wet paper can be controlled by regulating the air flow of the fan according to the change of the speed of the cylinder machine and the quantity of paper, and therefore the purposes of increasing the speed of the cylinder machine and guaranteeing the quality of finished paper can be achieved.
Description
Technical field
The utility model relates to a kind of two ends to cylinder mould machine wet end cylinder mould seals, and adopt blower fan to bleed, make the inside and outside mineralization pressure of cylinder poor, can accelerating fibers when the cylinder starching deposition dehydration on wire side, can improve paper machine speed and be unlikely to cause because the fibrage moisture is high at the couch roll place embossing problem; Overcome because of paper machine speed improve after sizing liquor because of the sliding slurry that the effect of scrubbing of the fiber of cylinder forms, prevent after the fibrage moulding destroyed because of sliding slurry, thereby the speed of a motor vehicle of cylinder mould machine can be improved more than 30%.
Background technology
Cylinder mould machine is a kind of paper making equipment simple in structure, the characteristics such as floor space is little, reduced investment, convenient operating maintenance that has, and good adaptability is arranged when the Production and Packaging paper product.This case is when producing fruit-nourishing sleeve bag outer bag paper, compound owing to the internal layer of yellow skin and black need being carried out in paper machine forming part, so adopt cylinder mould machine to produce.
The wet end moulding of cylinder mould machine is the filtration that utilizes the inside and outside water-head of rotary screen cage to produce, and fiber is attracted on wire side forms the l Water Paper page in dehydration.The l Water Paper page is at pressurizing and dehydrating when being surrounded by the couch roll of woollen blanket, and makes l Water Paper page absorption migration to woollen blanket because the specific area of woollen blanket is greater than wire side.
The fiber paper stock needs a large amount of dehydrations when cylinder forming, and the dehydrating amount of l Water Paper page is directly proportional to the dehydration arc length; In dehydration arc length one regularly, the pressure differential Δ p inside and outside dehydrating amount and cylinder mould is proportional.Therefore improve that pressure differential Δ p can improve dehydrating amount and the resistance that reduces to dewater is accelerated dewatering speed, to adapt to the raising of paper machine speed, thereby improve the production capacity in the cylinder mould machine unit interval, can prevent that the on-slip slurry improves quality of finished paper simultaneously.
The utility model content
The purpose of this utility model is to adopt a kind of air extractor at the cylinder mould machine cylinder mould.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of air extractor at the cylinder mould machine cylinder mould, be by the closed at both ends of cylinder mould, and tube connector is installed in perforate on the shrouding of transmission side, then at the other end of tube connector, a vacuum blower fan is installed.In order to adapt to the variation of paper machine speed, blower motor is installed frequency conversion adjustment device for high, and the air quantity of blower fan can be regulated with the variation of paper machine speed, the control of dehydrating amount when meeting the moulding of cylinder mould l Water Paper page.
The utility model has the advantage of: by the installation blower fan of bleeding, can improve the inside and outside pressure differential of rotary screen cage, and pressure differential can realize the control of l Water Paper page dehydrating amount by the air quantity of regulating blower fan with the variation of paper machine speed and page quantification, thereby reach the purpose that improves the cylinder mould machine speed of a motor vehicle, guarantees quality of finished paper.
The accompanying drawing explanation
The air extractor figure of cylinder part cylinder mould.
Fig. 1 is facing of cylinder mould air extractor;
Fig. 2 is the side view of cylinder mould air extractor.
The specific embodiment
Following structure accompanying drawing, be described in more detail the above-mentioned technical characterictic of the utility model and advantage
Refer to Fig. 1, shown in Figure 2, it is respectively the facing of the utility model cylinder part cylinder mould air extractor embodiment, top view and side view, and it comprises:
A kind of air extractor at the cylinder mould machine cylinder mould, be by the closed at both ends of cylinder mould, and tube connector is installed in perforate on the shrouding of transmission side, then at the other end of tube connector, a vacuum blower fan is installed.In order to adapt to the variation of paper machine speed, blower motor is installed frequency conversion adjustment device for high, and the air quantity of blower fan can be regulated with the variation of paper machine speed, the control of dehydrating amount when meeting the moulding of cylinder mould l Water Paper page.
Through the paper stock of sizing mixing, enter net cage 2 from advancing the side's of slurry Taper Pipe 1, after frost boiling, surf the Net from the ox horn road between arc bucket 3 and cylinder mould 4, the water-head inside and outside due to cylinder mould 4 produces filtration, makes the moulding on cylinder mould 4 of paper stock fiber, and the paper stock of small part overflows back approach system from the arc bucket; The page of moulding and woollen blanket are after the press dewatering of couch roll 5, because the specific area of woollen blanket 6 is larger than net, so the l Water Paper page shifts to woollen blanket from network.
Because the dehydration on the net of paper stock fiber depends primarily on the pressure differential Δ p inside and outside cylinder mould, therefore, adopt stainless steel shrouding 8 to seal at the two ends of cylinder mould, and open bleeding point 7 at transmission side, the blower fan 10 of bleeding passes through induced duct 9 from cylinder mould 4 internal air exhaustings, forms negative pressure, thereby improves the dehydration pressure reduction in cylinder mould 4, accelerate the paper stock fiber from dewatering speed on cylinder mould 4, finally improve the speed of service of whole paper machine more than 30%.
Above introduction belongs to explanatory elaboration to the utility model.Those skilled in the art understand, and within not breaking away from appended claim limited range, can be used for other cylinder types, but within all falling into protection domain of the present utility model.
