Description
Technical field
The utility model relates to a kind of paper making equipment, especially a kind of shoe press apparatus.
Background technology
From between more than 200 year of paper machine development, at press section and calecder section, two pairs of columniform pressure roller are the most frequently used squeezing or press polish modes.But because just line contact between two rollers, nip is very narrow, causes in press section dehydration difficulty; Not high in calecder section page smoothness.
For addressing these problems, shoe press has appearred in shoe-press from the early 1980s, existing it is used growing and is tending towards universal.This press type belongs to high squeezing and defeats press for extracting juice or be called wide nip press.Higher squeeze force is meant to compare with the concora crush roller to have higher squeezing specific pressure; Wide nip also is to compare with the squeezing of traditional pressure roller, and the l Water Paper page or leaf has the long time of staying in nip.Wide nip press is based on the formed nip of major diameter pressure roller (being also referred to as long nip press LNP), and the nip length of tradition squeezing is 20-90mm, and roller diameter is 1320-1800mm; And the nip length of shoe press is generally 50-300mm, helps page and dewaters better.In shoe-press, squeeze pressure is normally produced by the boot last nip of concave, and the boot last nip is by the belt on last pressure roller squeezing lower compression roller surface--and the resilient synthetic material squeezing of one deck pad produces.Shoe-press increases removing of squeeze water through improving the squeezing time, and it mainly is to utilize oil pressure that the shoe press plate of bottom is pressed on the pressure roller on top, is supporting the woollen blanket of l Water Paper page or leaf and the nip that adhesive tape passes through boot last pressing plate and last pressure roller.Initial shoe-press is open, and is as shown in Figure 1, about 20 liters of leakage of oil every day.
For this reason, develop the boots laminated structure of closed again, it is by pressure roller, press belt, and shoe press plate, the pressurization oil cylinder, siphon device and oil gas are discharged system, boots beam, whirligig, in-line, compositions such as belt stretcher.Its composition is in proper order: paper, cardboard or other thin-film materials get into the zone between pressure roller and the press belt, and the pressurization oil cylinder pressurizes to this thin-film material through shoe press plate.Hydraulic oil forms lubricating oil film and forms certain barometric gradient through the zone that in-line gets between press belt and the shoe press plate, and unnecessary oil is discharged system through siphon device and oil gas discharge system.Pressure roller rotate through the press belt that rubbing action drives through the belt stretcher tensioning as main transmission; Press belt driven rotary device is around the rotation of the center of boots beam; Thin-film material is achieved to be produced continuously.The boot last pressing plate is installed in the good flexible press belt of having of rotation, and is as shown in Figure 2, but structure is comparatively complicated, and the shoe press plate manufacturing is difficulty relatively, and flexible pipe, joint and instrument are numerous; In case instrument malfunction and pipeline leakage must shut down and remove press belt, and press belt are changed difficulty, costs an arm and a leg.And the pressure roller undercapacity often damages.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, a kind of shoe press apparatus is provided, and this apparatus structure is simple, makes easy to process; Flexible pipe, joint and instrument are rationally distributed, are easy to maintain easily, and cost is low, and pressure roller intensity is high; Bearing capacity is strong, and the life-span is long, and reliability is high.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of shoe press apparatus comprises the pressure roller and the press belt that match, and it is outside that press belt is enclosed within the boots beam; Be respectively arranged with belt stretcher, whirligig and shoe press plate on the boots beam; Press belt is through the belt stretcher tensioning, and press belt is enclosed within on the whirligig, and shoe press plate is between boots beam and press belt; The fore side spindle nose and the transmission side spindle nose at said boots beam two ends all are hollow structures; Fore side spindle nose end is provided with manhole and manhole cover, and boots beam inside is provided with the I-shaped beam slab muscle of band opening, is furnished with connecting line and instrument on the I-shaped beam slab muscle; Said shoe press plate global shape is a boot last, hold to derive to hold from importing to be the wedge shape distribution, and zone line is a spill.
The transmission side of said boots beam is the passage of connecting line and instrument, and fore side gets into the passage of boots beam for the attendant.
Form four zones between said shoe press plate and the press belt successively: static pressure district, dynamic pressure district, emptying district, oil level keep the district.
The roller core of said pressure roller is a thick cyclinder, and it is welded by two thick steel sheet bendings, and it has only two straight welds, and material is a mild steel, the weld seam annealing in process.
The utility model provides a kind of shoe press plate meter of new design; Under the situation of not dismantling press belt, the attendant can get into the inner maintenance of shoe press apparatus; A kind of high-intensity welding pressure roller body structure also is provided simultaneously.
The utility model is by pressure roller and bearing arrangement, press belt, and shoe press plate, the pressurization oil cylinder, siphon device and oil gas are discharged system, boots beam and bearing arrangement, whirligig, in-line, compositions such as belt stretcher.The pressurization oil cylinder, siphon device and oil gas are discharged system, whirligig, in-line, belt stretcher etc. all are fixed on the boots beam, pressurization oil cylinder and shoe press plate be linked together, through belt pressure roller are pressurizeed.
The utility model has designed the structure of boots beams, and fore side and transmission side spindle nose all are hollow, and line arrangement does not hinder attendant's turnover on I-shaped beam slab muscle.
The special shape of the shoe press plate of the utility model, make and formed four zones between it and the press belt: static pressure district, dynamic pressure district, emptying district, oil level keep the district, and it is interval to form good lubricated and pressure distribution.The utility model is owing to the roller core material of pressure roller and the design of technology, make pressure roller can bear higher pressure, and the life-span is longer, and reliability is higher.
