Abstract

The utility model provides a paper pulp squeezing device, which belongs to the field of paper-making machinery and comprises a press roller and a cleaning roller. Water absorption material is arranged on the surface of the cleaning roller, and the surface of the cleaning roller contacts with the surface of the press roller. The embodiment of the utility model additionally arranges the cleaning roller and absorbs the water on the surface of the press roller through the water absorption material on the surface of the cleaning roller, so as to alleviate or eliminate the rewetting phenomenon on the made paper due to the water on the press roller.

Description

A kind of paper pulp pressing device

Technical field

The utility model relates to a kind of papermaking equipment, particularly a kind of paper pulp pressing device.

Background technology

Existing paper mill is mechanization day by day all, reduces manual operation to save the labour and to raise the efficiency in whole production line.Before paper is dried, need push paper pulp by pressure roller, to extrude the moisture in the paper pulp as far as possible, to improve the efficient of baking operation.

The outer surface of existing pressure roller is smooth, the water in the paper pulp can be extruded when extruding paper pulp like this.But, therefore have the surface that part water is stayed pressure roller because the surface of pressure roller is very smooth.In continuous firing, the water on the pressure roller can be got back in the paper pulp again like this, causes the paper that produces wet phenomenon to occur back.

In the prior art, have the water delivery groove or the mode of blind hole are set on the pressure roller surface.This mode all can cause the paper pulp surface irregularity after the squeezing, has influenced the quality of paper greatly.Simultaneously, water delivery groove and blind hole all can only play very little effect, can not thoroughly solve the problem of squeezing roller strap water.

The utility model content

The pressure roller smooth surface causes water easy-storing in the prior art in order to solve, and the pressure roller surface is provided with water hole and blind hole can cause the squeezing back problem that paper pulp is rough and hydrophobic effect is also bad, the utility model embodiment has proposed a kind of paper pulp pressing device, and the existing pressing device of can comparing has better effect.Described technical scheme is as follows:

The utility model embodiment has proposed a kind of paper pulp pressing device, comprises pressure roller, clearer, and described clearer surface is provided with absorbent material, and described clearer surface contacts with described pressure roller surface.

Preferred as technique scheme, described clearer is one or more.

Preferred as technique scheme, described clearer has the cleaning roll shaft, and described cleaning roll shaft links with described squeezing roll shaft.

Preferred as technique scheme, described cleaning roll shaft is connected linkage by belt with described pressure roller through-drive.

Preferred as technique scheme, the diameter of described clearer is the 10%-20% of the diameter of described pressure roller.

The beneficial effect of the technical scheme that the utility model embodiment provides is: the utility model embodiment absorbs the moisture on pressure roller surface by increasing a clearer by the absorbent material on clearer surface.Can when pressure roller are worked, draw the moisture on pressure roller surface like this, cause the paper that produces wet phenomenon to occur back to reduce or thoroughly to solve because of squeezing roller strap water.

Description of drawings

In order to be illustrated more clearly in the technical scheme of the utility model embodiment, to do one to the accompanying drawing that uses among the embodiment below introduces simply, apparently, below listed accompanying drawing only be embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of the utility model preferred embodiment.

1. pressure roller;

11. squeezing roll shaft;

2. clearer;

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing.

The paper pulp pressing device that the utility model first preferred embodiment proposes, its result comprises pressure roller 1 and clearer 2 as shown in Figure 1.Wherein, the outer surface of clearer 2 is made by absorbent material.As shown in Figure 1, pressure roller 1 contact with the surface of clearer 2.

First preferred embodiment of the present utility model has proposed a kind of paper pulp pressing device, can make the moisture of the absorbent material absorption pressure roller remained on surface on clearer surface when pressure roller are worked, and to prevent back wet phenomenon, improves the quality of paper.

As shown in Figure 1, pressure roller 1 have squeezing roll shaft 11, and clearer 2 has cleaning roll shaft 21, and described squeezing roll shaft 11 is in transmission connection with described cleaning roll shaft 21.Wherein, the mode of transmission can be for multiple, for example by gear or pass through belt.Like this can be so that clearer 2 rotates with pressure roller 1, to improve soaking effect.For example, as shown in Figure 1, squeezing roll shaft 11 is in transmission connection by belt 3 with cleaning roll shaft 21 and rotates.

Certainly, can also be designed to squeeze roll shaft 11 and connect different drive units respectively, make pressure roller 1 rotate with different angular speed with clearer 2 with cleaning roll shaft 21.This mode also is more convenient for changing clearer 2, and does not need to stop the work of pressure roller 1.

As shown in Figure 1, for the ease of changing the absorbent material on clearer 2 surfaces, a plurality of clearers 2 can be set.As shown in Figure 1, what clearer 2 can be provided with is smaller, so that dismounting at any time.Simultaneously, a plurality of clearers 2 are set.Like this can be when a clearer to be changed absorbent material, other clearer works on.Preferably, diameter that can clearer 2 is set to the 10%-20% of pressure roller 1 diameter.Like this can be so that clearer 2 more quick detachable, replacings.

Because when suction, rotate the convenient clearer 2 that distributes along pressure roller 1, water absorption can reduce successively.The clearer 2 of the most close pressure roller 1 Exit Point, the moisture content on pressure roller 1 surface that is contacted is maximum, needs often to change.And clearer 2 water absorptions after leaning on this moment can be smaller, do not need frequent replacing.

By the foregoing description as can be seen: the utility model embodiment has the clearer of absorbent material by setting up a surface, and the clearer surface is contacted with the pressure roller surface.So just can when pressure roller are worked, make the moisture of the absorbent material absorption pressure roller remained on surface on clearer surface,, improve the quality of paper to prevent back wet phenomenon.In order to improve the effect of suction, can be arranged to clearer and rotate with pressure roller.The surface of clearer is contacted with the pressure roller surface in turn, reduce to prevent the water absorbing capacity that causes after the long-time suction of absorbent material.Simultaneously, in order to improve soaking effect and to be convenient to change clearer, can be along a plurality of clearers of surface difference of pressure roller.When a clearer soaking effect reduced, follow-up clearer can be proceeded suction like this.And when a clearer is changed, do not need break-off, can work on by other clearers.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
