Description

[Detailed Description of the Invention] The present invention relates to a dewatering device using a nonwoven fabric roll.

Recently, various dehydration devices using airflow have been devised, and many of them are in practical use.

However, with these mechanisms, the rotating or contacting rolls generally have water absorbing properties themselves, and the suction dewatering by a certain section is so-called local suction, so although a considerable dewatering effect can be expected, it is still not sufficient and has not been widely used. cannot be used as a suction dehydration device.

In addition, since they are generally made of metal, they can suffer from scratches due to surface friction with the rolls, making them unusable depending on the type of fabric.

Furthermore, the roll is a perforated cylinder and a slit cylinder, and has high-pressure gas permeability, and since this high-pressure gas passes through the porous or slit parts, it must be a considerably high-pressure gas, and its capacity must be increased. There are structural and economic problems.

In view of the above, the present invention has the following advantages: the impermeability of the non-woven fabric roll to appropriate high-pressure gas; It is an object of the present invention to provide a dewatering device using a nonwoven fabric roll that can efficiently dehydrate using force.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

Reference numeral 1 denotes a cylindrical shaft body having bearing parts 2, 2a at both ends.A hollow part 3 facing in the axial direction is opened in this shaft main body 1, and a hollow part 3 connected to the hollow part 3 is formed on the circumferential surface of the shaft main body 1. A large number of communicating holes 4 are opened.

Further, at least one of the hollow portions 3 of the shaft body 1 is an opening 5, and a suction mechanism (not shown) such as a pump is communicated with the opening 5 via a hose 6 or the like.

Side plates 7.9 are provided on both ends of the shaft body 1 configured in this manner.
are fixed to each other, and a roll body 10 is provided on the shaft body 1, which is formed by overlapping a large number of nonwoven fabrics 8 in a compressed manner, for example, by press molding, with side plates 7 and 9 interposed therebetween. A nonwoven fabric roll A of the invention is constructed.

A wind barrel 11 has a pressure chamber 12 inside, and a nozzle 14 is provided at its lower end.

This nozzle 14 is attached to the wind barrel 11 with a stopper.

Preferably, the nozzle 14 is constructed as a two-part member as in this example, so that the width of the slit 13 provided therein can be adjusted as appropriate.

Note that both ends of the nozzle 14 in the width direction (perpendicular direction to the drawing) are sealed with seal members.

Each nozzle 14 is made of a thick member, and the tips of the slits 13 are formed into a skirt portion 13a having approximately the same circumference as the circumference of the roll body 10, or an expanded shape 13b, as will be described later. It is thought that it is possible to expand the pressure contact area of the fabric.

Note that high-pressure air, steam, or other gas is pressurized into the pressure chamber 12 via a blower and a hose (not shown).

An appropriate interval is provided between the tip of the nozzle 14 and the roll body 10 of the nonwoven fabric roll A, and the fabric B is configured to pass through this interval.

To explain the case where fabric B is dehydrated using the dewatering apparatus configured in this way, in the example shown in FIG.
If the surface of the nonwoven fabric roll A' is wet, the nonwoven fabric roll A is pressed through a rubber roll C, etc.
' Push the moisture into the inner surface of the roll body 10,
In addition, suction force is used to attract the hollow portion 3 of the shaft body 1.

The fabric B fed through the guide rolls is
First, it is attached to a nonwoven fabric roll A, and during this attachment, moisture adhering to the surface of the fabric B is mainly sucked into the roll body 10 by the suction force of the nonwoven fabric roll A, which will be described later, and the water absorbency of the nonwoven fabric 8 itself.

When the fabric B reaches the above-mentioned spacing, as shown in FIG. 3 which shows an enlargement of this example (however, the shape of the slit 13 has a skirt portion 13a in this example).

), is pressed against the outer peripheral surface of the nonwoven fabric roll A by the high pressure gas ejected from the slit 13 of the nozzle 14, and
The slit side is pressed.

As a result, the water impregnating the fabric B is pushed out, and is also sucked into the roll body 10 by the suction force of the suction mechanism connected to the nonwoven fabric roll A and the water absorbency of the nonwoven fabric 8 itself, and the water is drawn from the through hole 4 to the hollow part 3 to the opening. 5 → The water is suctioned and dehydrated through a hose and discharged to the outside.

In this way, the water content of fabric B is removed.

In the example shown in FIG. 4, fabric B is fed along with nonwoven fabric roll A via a guide roll, and at the time of this attachment, the suction force and water absorption of nonwoven fabric roll A are used to mainly absorb fabric B. sucks up moisture adhering to the surface.

When the fabric B reaches the above-described spacing, it is pressed and pressed by the high-pressure gas ejected from the slit 13 in the same manner as in the previous example.

In this case, it is considered that the expanded shape 13b of the slit 13 allows the pressure contact area to be expanded.

As a result, the water impregnated in the fabric B is pushed out, dehydrated by suction, and removed in the same manner as in the previous example.

As detailed above, the present invention has a structure in which a nonwoven fabric roll is provided with a suction force and nozzles having slits at appropriate intervals are provided on this nonwoven fabric roll, so that the fabric fed to the nonwoven fabric roll is relatively wide. It has the effect of being pressed against the nonwoven fabric roll over a wide range, and together with the suction force and water absorption of the nonwoven fabric roll, efficient suction dewatering becomes possible.

In addition, the roll body of the nonwoven fabric roll is appropriately impermeable and has water absorbency itself, so unlike the conventional method of blowing away moisture using this type of high-pressure gas, the present invention uses a suction and blotting method. be.

Furthermore, since it is a non-woven fabric roll, the occurrence of one-scratch of the fabric can be reduced.
