Abstract
The utility model relates to the technical field of the papermaking equipment, in particular to a papermaking dehydrating device, which comprises a boot press roller and a backup roller, wherein the boot press roller comprises a press boot, a boot beam and a boot sleeve, the upper surface of the press boot is in a boot-shaped structure, the boot beam and the press boot are arranged inside the boot sleeve, the boot beam supports the press boot, and a press area is formed at a squeezing position of the press boot and the backup roller. The width of the press area is set as 280mm. Compared with the dehydrating device of the prior art, since a squeezing part of a squeezing roller is set as the boot-shaped structure, the width of the press area is increased, the dehydrating efficiency is improved, and the energy consumption of the subsequent drying can be reduced.
Description
Technical field
The utility model relates to the paper making equipment technical field, particularly relates to a kind of papermaking dewater unit.
Background technology
In paper industry; Page still contains a large amount of moisture behind net part forming; Generally must the l Water Paper page or leaf be carried out processed and send to drying again, directly not send to drying and will consume a large amount of steam, and gained page tightness is low, rough surface, intensity are low if do not dewater in advance.Only along a narrow alignment paper wood is exerted pressure by pressure roller but carry out the dry device of l Water Paper page or leaf at present, be difficult to the moisture of extruding out preferably, the water separation capability difference influences follow-up sheet processing and product quality.
The utility model content
The purpose of the utility model is to avoid weak point of the prior art and provides a kind of dehydrating effect good papermaking dewater unit.
The purpose of the utility model realizes through following technical scheme.
A kind of papermaking dewater unit comprises pressure roller and back flow roll, pressure roller and back flow roll mutual extrusion; Pressure roller comprise pressure shoes, boots beam and boots cover, and the upper surface of pressure shoes is set to the boot-shaped structure, and boots beam and pressure shoes are arranged at the inside of boots cover; The boots beam supports pressure shoes, and pressure shoes and back flow roll extruding place form nip.
Wherein, the width of nip is set to 250 ~ 350mm.
Wherein, the width of nip is set to 280mm.
Wherein, the boots beam is set to I-shaped structure.
Wherein, the upper end of boots beam compresses the lower end of boots.
The beneficial effect of the utility model: a kind of papermaking dewater unit, comprise pressure roller and back flow roll, pressure roller comprise pressure shoes, boots beam and boots cover; The upper surface of pressure shoes is set to the boot-shaped structure; Boots beam and pressure shoes are arranged at the inside of boots cover, and the boots beam supports pressure shoes, and pressure shoes and back flow roll extruding place form nip.Increase nip width widely because the press section of pressure roller is set to the boot-shaped structure, improved dewatering efficiency, reduced follow-up energy consumption for drying.
Description of drawings
Utilize accompanying drawing that the utility model is further specified, but the content in the accompanying drawing does not constitute any restriction to the utility model.
Fig. 1 is the structural representation of an embodiment of a kind of papermaking dewater unit of the utility model.
Include among Fig. 1:
1 boots pressure roller, 11 boots covers, 12 pressure shoes, 13 boots beams, 2 back flow rolls.
The specific embodiment
In conjunction with following examples the utility model is described further.
embodiment 1.
A kind of papermaking dewater unit, pressure roller 1 comprise pressure shoes 12, boots beam 13 and boots cover 11, and the upper surface of pressure shoes 12 is set to the boot-shaped structure, and boots beam 13 is arranged at boots with pressure shoes 12 and overlaps 11 inside, and boots beam 13 supports pressure shoes 12, and pressure shoes 12 forms nip with back flow roll 2 extruding place.In the present embodiment, the width of nip is set to 250 ~ 300mm.Nip width is about 10 times of transmission nip width, and line pressure is higher than conventional roll line ball property pressure, has improved the page dewatering efficiency, because moisture reduces in the paper, and the energy consumption of having saved follow-up drying section.
In the present embodiment, boots beam 13 is set to I-shaped structure, and the upper end of boots beam 13 compresses the lower end of boots 12.Boots beam 13 is designed to I-shaped structure, can guarantee the rigidity and the intensity of boots pressure roller.The roller core of pressure roller 1 is static, and boots that flexible material is processed cover 11 is installed in through pressing plate on the handtailor bearing of roller core and runs up, thereby has improved the speed of a motor vehicle of paper machine.
embodiment 2.
A kind of papermaking dewater unit of present embodiment and the difference of embodiment 1 are that the width of present embodiment nip is set to 280mm.Suitable nip width helps improving moisture and sloughs rate, reduces moisture in the paper.Other structure and the principle of present embodiment are identical with embodiment 1, repeat no more at this.
Should be noted that at last; Above embodiment only be used to explain the utility model technical scheme but not to the restriction of the utility model protection domain; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model, and do not break away from the essence and the scope of the utility model technical scheme.
