Abstract
The invention discloses a papermaking dehydration device which comprises a press roll, a back roll and a controller, wherein the press roll comprises a press boot, a boot beam and a boot sleeve; the upper surface of the press boot is arranged to be boot-shaped structure, the boot beam and the press boot are arranged inside the boot sleeve, the boot beam supports the press boot, and the press roll and the back roll squeeze each other, so that a pressing area is formed; the controller is fixed on one side of the boot beam; the controller is connected with the press roll to be used for adjusting the position of the press roll. According to the invention, the travelling is stable and uniform, the edge folding, creasing and other phenomena are avoided, and the smooth dehydration of wet paper sheets can be kept, so that the uniform dehydration can be implemented, and the dehydration effect of wet paper sheets is improved; pulp flinging and paper breakage are avoided when paper sheets are discharged out of a paper-making screen, so that the papermaking production efficiency and papermaking product quality are guaranteed.
Description
Technical field
This
inventionrelate to paper making equipment technical field, particularly relate to
a kind of papermaking dewater unit.
Background technology
In existing paper industry technology, page still contains a large amount of moisture after net part forming, generally l Water Paper page must be carried out processed and send to drying again, directly send to drying if do not dewater in advance and will consume a large amount of steam, and gained page tightness be low, rough surface, intensity are low.But the device carrying out wet paper page drying position at present only applies pressure along a narrow alignment to paper wood by pressure roller, is difficult to press preferably squeeze the water out, the water separation capability difference follow-up sheet processing of impact and product quality.
This
inventionobject be to avoid weak point of the prior art and the papermaking dewater unit providing a kind of dehydrating effect good.
This
inventionthe technical scheme adopted is:
a kind of papermaking dewater unitcomprise pressure roller, back flow roll, controller, described pressure roller comprise pressure shoes, boots beam, boots cover, the upper surface of described pressure shoes is set to boot-like structure, described boots beam and described pressure shoes are arranged at the inside of described boots cover, described boots beam supports described pressure shoes, and described pressure roller and back flow roll extrude mutually, forms a nip; Described controller is fixed on boots beam side, and described controller is connected with described pressure roller, for adjusting the position of described pressure roller;
Also comprise humidity sensor and alarm, described humidity sensor and alarm are connected with described controller respectively, described humidity sensor is arranged on described nip position, for obtaining the humidity of described nip, and the numerical value of measurement is sent to described controller, described controller controls the duty of alarm according to the numerical value received.
Preferably, described alarm is voice guard.
Preferably, the width of described nip is set to 500 ~ 800mm.
Preferably, described boots beam is set to I-shaped structure.
Preferably, described pressure roller comprise carbon fiber layer, resin bed, metal level and roll centre, and the outside of described roll centre is disposed with metal level, resin bed and carbon fiber layer, and the outer setting of described carbon fiber layer has nano coating.
This
inventionpapermaking dewater unit, press section due to pressure roller is set to boot-like structure and substantially increases nip width, improve dewatering efficiency, reduce follow-up energy consumption for drying, simultaneously when l Water Paper page enters to certain one side offset rows, and when being triggered to the controller of corresponding side, the pressure roller controlling this limit unclamps by controller, namely compacted l Water Paper page retracts normal course by the pressure roller of opposite side, then this side pressure roller recovers to compress immediately, thus make l Water Paper page in dehydration, to advance even, also avoid occurring flanging, the phenomenons such as gauffer, l Water Paper page is made to keep plane, dehydrated, thus reach even dehydration, also improve the dehydrating effect of l Water Paper page simultaneously, page is made to avoid when going out papermaking wire-cloth getting rid of slurry, disconnected paper, thus ensure paper efficiency and papermaking product quality.
