Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous dewatering apparatus that uses a space formed by four rolls as a main structure as a negative pressure chamber.

As a device for continuously dewatering (dewatering) a liquid-containing fabric that is continuously transferred, for example, a squeezing mangle consisting of a pair of pressure rolls that are pressed against each other is well known. The squeezing means, which is a combination of 40 liters, has a limit to the pressure force applied to the fabric and is often unable to produce a sufficient amount of internal liquid.

For example, a drawing mangle made up of two pressure rolls can only be made up to about 50 inches, so
It was not possible to expect more ('Ij liquid (dehydration)). Therefore, in order to increase the squeezing effect, for example, as shown in Fig. First, a squeezing device is used to draw liquid into the space (in the space formed by these rolls) using the contact pressure of the rolls pressed against each other as a negative pressure and the negative pressure in the space (in the space). However, with this diaphragm device, is it possible to continuously pass through the coating? 51 Liquid fabric hanging (e) must be guided in a 100-degree bend by a single roll (IL), and since it cannot be moved in a straight line, there is a problem that wrinkles occur in the fabric during this bending guide. there were.

Therefore, in order to prevent the occurrence of wrinkles, in order to make the fabric move linearly, for example, as shown in Fig. 2,
Two pairs of squeeze rolls (a), body) and (a').

(Intermediate rolls (d) and (d) are interposed between a and K, and a space formed by these squeezing rolls, intermediate rolls (d), and K (within b being a negative pressure chamber) , has also proposed a method that measures the internal fluid of the fabric passing through this negative chamber,
In this device, each roll (a) is
, (a'), and (d) are formed to be long, the intermediate roll (d) in particular is distorted (curved) in the direction of the negative pressure chamber due to the action of negative pressure, and the space between the squeeze roll and the intermediate roll is There was a problem in that a gap was created in the chamber, making it impossible to maintain an effective negative pressure state within the chamber.

The present invention has been made to solve these problems, and by combining four seal rolls and a cylindrical seal plate, a dewatering device that eliminates the conventional drawbacks and achieves effective continuous dewatering. - The purpose is to provide

Hereinafter, the present invention will be explained in detail based on the embodiments shown in FIGS. 3 to 5.

1 is a base frame, and this base frame 1 has four rubber rolls 2+
, 2! , 2m, and 24 are rotatably supported, but in this embodiment, the rubber rolls 21 and 2m are rotatably supported. Furthermore, the rubber rolls 2s and 24 are combined so as to be pressed against each other, and the rubber rolls 21 and 21 are also pressed against each other.
and 24 are separated. Reference numeral 3 denotes a cylindrical sealing plate made of gold f4 located in a space surrounded by four rubber rolls, and this cylindrical sealing plate 3 is in contact with all of the rubber rolls. As shown in FIG. 5, this sealing plate 3 has both slits 4 that open in the diametrical direction in other parts of the cylindrical body except for both ends.
This slit 4 is formed as a hole through which the fabric passes. Reference numeral 5 denotes a bearing that supports the rubber roll, and this bearing 5 is attached to the base frame 1 so that it can be adjusted freely. 6 is a drive gear fixed to the rubber roll, and each rubber roll is rotated at a constant speed in the arrow direction via these drive gears. Reference numeral 7 designates end face seal plates which are brought into contact with both end faces of each rubber roll and close the cylindrical portions at both ends of the cylindrical seal plate 3. 8 is a pressure gas supply port;
9 is a negative pressure pipe located inside the cylindrical seal plate 3, and the negative pressure pipe 9 abuts in the width direction of the fabric 11 passing through the slit 4 of the cylindrical seal plate 3. The fabric is arranged like this, and the fabric 11
A vacuum port 10 in the direction of the generatrix is formed on the sliding contact surface with.

Further, both ends of this negative pressure pipe 9 are communicated with the atmosphere or connected to a vacuum mechanism (not shown). 12 is a drain outlet.

The above is the configuration of this embodiment.Next, to describe its operation, it is located between two pairs of rubber rolls that are pressed against each other and six pairs of rubber rolls, and is pressed against any of these rolls. Along with being.

A cylindrical seal plate forming a pair of slits that open toward the contact pressure surface of each pair of rubber rolls, and a cylindrical seal plate that closes both ends of the cylindrical seal plate and is in contact with both ends of each rubber roll. Since it has an end seal plate, the inside of the cylindrical seal plate is a sealed chamber (a) that is isolated from the outside.
is formed. If pressurized air is supplied into this sealed chamber (a) from the gas supply port 8, this sealed chamber (a) will become a high pressurized chamber, and the high pressure gas in this sealed chamber (a) will be supplied through a negative pressure pipe. 9
is about to be discharged to the outside (into the atmosphere) with the vacuum port 10 vertical. Therefore, due to the exhaust pressure passing through the vacuum port 10, moisture contained in the fabric is transferred to the outside through the negative pressure pipe (
(into the atmosphere) and undergoes the desired dehydration.

If the internal pressure in the sealed chamber (a) is increased, the exhaust pressure will be increased, and the dehydration effect will also be enhanced. Furthermore, even if a vacuum mechanism is connected to the negative pressure pipe, the fabric that comes into contact with the vacuum port 10 of the negative pressure pipe can be effectively dehydrated.

As described above, the present invention is arranged between two pairs of rubber rolls and six pairs of rubber rolls that are in pressure contact with each other, is in pressure contact with any of these rubber rolls, and has an opening facing the pressure surface of the six pairs of rubber rolls. a cylindrical seal plate forming a pair of slits, a shoulder seal plate that closes the openings at both ends of the cylindrical seal plate and comes into contact with the end surface of each rubber roll; A negative pressure pipe is located inside and has a suction dehydration port that contacts the fabric surface passing through a slit provided in this cylindrical seal plate, and supplies η1 pressure air to the inside of the @origin-shaped seal plate. Since it is equipped with a pressurized gas supply port, it is possible to supply pressurized air into the sealed chamber formed by the four rubber rolls, the end seal plate, and the cylindrical seal plate, or to blow the negative pressure tape.・By connecting to the Neem mechanism, strong exhaust pressure is generated at the vacuum port of the negative pressure pipe,
Therefore, the moisture in the amount of cloth that is brought into contact with the vacuum port is effectively dehydrated and removed.
