Description
Technical field
This utility model relates to papermaking equipment apparatus field, particularly relates to the main press device of a kind of high water rate.
Background technology
Papermaking operation include slurrying, modulate, the step such as manufacture paper with pulp, and in manufacturing paper with pulp, first screening, then wet end, squeeze again, the operations such as finally drying, l Water Paper is guided between two shaping rods having felt by squeezing exactly, the extrusion of mat shaping rod and the water sorption of felt, l Water Paper is made further dehydration, and make papery relatively tight, to improve paper, increase intensity.Existing papermaking press portion typically uses plain press roller that l Water Paper page is carried out press dewatering, plain press roller has the roll surface of flat smooth, l Water Paper page frame table after plain press roll-in is squeezed is smooth, but due to its circumferential outer surface unusual light of plain press roller, moisture easily rests on pressure roller surface, the phenomenon of squeezing roller strap water often occurs, during the moisture on pressure roller surface can return to the l Water Paper page of follow-up squeezing in expressing process, cause the phenomenon of page rewetting, affect the squeezing effect of l Water Paper page.
China Patent No.: 201220309800.8 disclose the main press device of a kind of high water rate, it includes roller and lower roll, glazing felt is carried on described upper roller, the contact surface of described upper roller and lower roll is line nip, lower felt is carried on described lower roll, it is precompressed zone before described glazing felt and upper roller contact point to line pressure, described upper roller deflection paper feed side.By experiment test, this device show that best angle is 128 degree, increase precompressed zone, before entering line pressure, have begun to dehydration, when entering line nip, the change of position, water flow to Angulation changes, owing to the deadweight flow velocity down of water is accelerated, reach Quick drainage, during but the moisture on pressure roller surface can return to the l Water Paper page of follow-up squeezing in expressing process, cause the phenomenon of page rewetting, affect the squeezing effect of l Water Paper page.
Utility model content
Therefore, for above-mentioned problem, this utility model provides the main press device of a kind of high water rate, and it mainly solves pressure roller surface moisture residual, the problem causing the phenomenon of page rewetting in prior art.
For achieving the above object, this utility model have employed techniques below scheme: the main press device of a kind of high water rate, including main press roller and the secondary pressure roller that is arranged on main press roller side, the surface configuration of described main press roller has a plurality of blind hole, described secondary pressure roller includes main shaft, the rhone of plural number two end faces of bar lateral direction penetrating it is provided with on the outer surface of described main shaft, it is provided with pressure roller outside the outer surface of described main shaft and around main shaft, it is provided with plurality of through holes on the outer surface of described pressure roller, it is provided with collect cavity between described pressure roller and main shaft, the water inlet of described collect cavity is connected with through hole by water pipe, the outlet of described collect cavity is provided with check valve, described collect cavity is that elastomeric material is made, a plurality of spring it is additionally provided with between described pressure roller and main shaft.
Further, main shaft extrusion spring deflection main press roller during described secondary pressure roller work, form eccentric shape.
Further, the number of described secondary pressure roller is one or more, and is surrounded on main press roller outer surface.
nullBy using preceding solution，The beneficial effects of the utility model are: the main press device of this high water rate，It is located at outside main shaft by press-roller sleeve，And between pressure roller and main shaft arrange the resilient collect cavity of tool and spring，During work，Main shaft extrusion spring deflection main press roller，Also extrude collect cavity simultaneously，Form eccentric shape，When woollen blanket clips wet web in time passing through between main press roller and secondary pressure roller，Spring is in squeezed state，Increase the pressure of pressure roller extruding main press roller，Increase water rate，When wet web is extruded simultaneously，Moisture is got in collect cavity by the through hole on pressure roller，Check valve on the outlet of collect cavity is opened，Moisture flows out，Discharged by the rhone on main shaft surface，When main press roller is to be separated with secondary pressure roller，The spring being extruded restores to the original state，The collect cavity being simultaneously extruded restores to the original state under natural resiliency effect，Because the effect of check valve，Collect cavity recovery process is formed suction，Absorb the moisture on wet web and the moisture of secondary roller surface residual further，The blind hole of main press roller surface configuration prevents its remained on surface moisture，Cause the phenomenon of page rewetting；Further, the number of secondary pressure roller is one or more, and is surrounded on main press roller outer surface, by arranging multiple secondary pressure roller, increases the dehydrating amount of wet web, reduces drying time, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the sectional view in Fig. 1 at A-A.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
This utility model embodiment is:
With reference to Fig. 1 and Fig. 2, a kind of main press device of high water rate, including main press roller 1 and a secondary pressure roller 2 being arranged on main press roller 1 side, the surface configuration of described main press roller 1 has blind hole, described secondary pressure roller 2 includes main shaft 3, the rhone 31 of two end faces of lateral direction penetrating it is provided with on the outer surface of described main shaft 3, it is provided with pressure roller 4 outside the outer surface of described main shaft 3 and around main shaft 3, it is provided with through hole 41 on the outer surface of described pressure roller 4, it is provided with collect cavity 5 between described pressure roller 4 and main shaft 3, the water inlet of described collect cavity 5 is connected with through hole 41 by water pipe, the outlet of described collect cavity 5 is provided with check valve 6, described collect cavity 5 is made for elastomeric material, it is additionally provided with spring 7 between described pressure roller 4 and main shaft 3.
nullWorking method of the present utility model is: the main press device of this high water rate，By the resilient collect cavity of tool 5 arranged between pressure roller 4 and main shaft 3 and spring 7，During work，Main shaft 3 extrusion spring 7 is partial to main press roller 1，The most also extruding collect cavity 5，Form eccentric shape，When woollen blanket clips wet web in time passing through between main press roller 1 and secondary pressure roller 2，Spring 7 is in squeezed state，Increase secondary pressure roller 2 and extrude the pressure of main press roller 1，Increase water rate，When wet web is extruded simultaneously，Moisture is got in collect cavity 5 by the through hole 41 on pressure roller 4，Check valve 6 on the outlet of collect cavity 5 is opened，Moisture flows out，Discharged by the rhone 31 on main shaft 3 surface，When main press roller 1 is to be separated with secondary pressure roller 2，The spring 7 being extruded restores to the original state，The collect cavity 5 being simultaneously extruded restores to the original state under natural resiliency effect，Because the effect of check valve 6，Collect cavity 5 recovery process is formed suction，Absorb the moisture on wet web and the moisture of secondary pressure roller 2 remained on surface further，The blind hole of main press roller 1 surface configuration prevents its remained on surface moisture，Cause the phenomenon of page rewetting.
