Abstract
The utility model relates to a kind of three pressure roller press-dehydrating structures of paper machine, comprise top roll, lower roll, lower felt, top roll and lower roll are corresponding up and down setting, lower roll is set with lower felt, on the roller of lower roll, uniform interval is shaped with blind hole, between top roll and lower roll, be provided with finished product paper, it is characterized in that: outside top roll, be set with top felt, the roller outer rim cylinder of top roll is uniform is shaped with blind hole.By the application of this technology, in production process, the tension force of paper reduces 15%, and by front baking cadre, not easily broken paper, reduces paper-making process and to break paper rate, make paper machine speed improve 60m/min.
Description
Technical field
The utility model belongs to pulp technology for making paper, relates to three press-dehydrating technology, especially a kind of three pressure roller press-dehydrating structures of paper machine.
Background technology
In manufacture body paper process, in three pressure roller press-dehydrating structures of common paper machine, comprise top roll, lower roll and one deck felt, wherein top roll is stone roll, and lower roll is blind-hole roll, and stone roll does not arrange felt, and lower roll is blind-hole roll and arranges felt.In paper-making process, the felt of lower roll attachment with drive displacement together with shaping paper between stone roll, because stone roll is smooth flat, product paper easily and stone roll be bonded together and go together.Trace it to its cause, be product paper when extrusion dehydration, forms negative pressure between stone roll and product paper, cause shaping paper to stick on stone roll, thus it is easily broken to form paper curl overtension, has a strong impact on the raising of the speed of a motor vehicle.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of three pressure roller press-dehydrating structures of paper machine, when this structure effectively can solve product paper dewatering and the adhesion phenomenon that produces of top roll, improves the workmanship of product paper.
The purpose of this utility model is achieved by the following technical solution:
A kind of three pressure roller press-dehydrating structures of paper machine, comprise top roll, lower roll, lower felt, top roll and lower roll are corresponding up and down setting, lower roll is set with lower felt, on the roller of lower roll, uniform interval is shaped with blind hole, between top roll and lower roll, be provided with finished product paper, it is characterized in that: outside top roll, be set with top felt, the roller outer rim cylinder of top roll is uniform is shaped with blind hole.
And described blind hole percent opening is 20-30%, blind hole is divided into dark blind hole and shallow blind hole, and dark blind hole and shallow blind hole are for being spaced.
And described blind hole is for being obliquely installed, and its angle of inclination is 30-55 °.
Advantage of the present utility model and good effect are:
1, the utility model presses stone roll and is replaced by blind-hole roll and adds cover top felt by three, interval between product paper and top roll is made to have felt, product paper is not directly contacted with top roll, reaches product paper and no longer produce pinning phenomenon with top roll, effectively improve the workmanship of product paper.
2, the utility model owing to being set with felt on top roll, therefore can realize the double dewatering of product paper, effectively improve dewatering efficiency, and the stability of paper before entering drying cylinder, and then also improve the speed of a motor vehicle.
3, the utility model is shaped with the different blind hole of the depth on the roller of top roll, effectively can absorb water during roll-in product paper, avoid the formation of negative pressure, solves the adhesion phenomenon of product paper and top roll.
4, by the application of this technology, in production process, the tension force of paper reduces 15%, and by front baking cadre, not easily broken paper, reduces paper-making process and to break paper rate, make paper machine speed improve 60m/min.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural front view of the utility model top roll;
Fig. 3 is that the A-A of Fig. 2 is to cross-sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model thus.
A kind of three pressure roller press-dehydrating structures of paper machine, comprise top roll 2, lower roll 7, lower felt 5, top roll and lower roll are corresponding up and down setting, and lower roll is set with lower felt, on the roller 6 of lower roll, uniform interval is shaped with blind hole, is provided with finished product paper 4 between top roll and lower roll.
Innovative point of the present utility model is:
1, outside top roll, be set with top felt 3, this top felt and lower felt are that identical material is made.
2, the roller 1 outer rim cylinder of top roll is uniform is shaped with blind hole, and its percent opening is 20-30%, and the best is 21.3%; This blind hole is divided into dark blind hole 8 and shallow blind hole 9, and dark blind hole and shallow blind hole are for being spaced.
3, the dark blind hole that the roller of described top roll is made and the degree of depth of shallow blind hole set according to actual needs, and blind hole is for being obliquely installed, and its angle of inclination is 30-55 °, and the best is 45 °.This angle can make the water of top felt be dewatered fully.
