Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing device for pressure sealing a high-pressure steamer used for high-pressure treatment of textile products.

High-pressure steamers for treating textile products at high temperature and high pressure by applying high-temperature, high-pressure saturated steam to textile products are already known. The present inventor has been conducting research over a long period of time regarding a sealing device for introducing steam into the steamer or leading it out of the steamer, and has filed numerous applications regarding the sealing device.

This type of sealing device that has already been developed includes one equipped with multiple sealing rubber rolls, or one configured by combining the multiple rubber rolls with two or more stages of decompression chambers. In a sealing device equipped with a sealing rubber roll, the sealing rubber roll is heated to approximately the same temperature as the steamer internal temperature (approximately 160°C), causing deterioration, and furthermore, it is difficult to maintain the sealing effect over a long period of time due to wear, etc. It was something.

In addition, when the material to be processed is continuously led out to the differential pressure processing tank, a plurality of side chambers are sequentially provided on the wall surface of the inlet/outlet part of the processing tank via partition walls, and each opening provided in the partition wall is provided with a plurality of side chambers. A sealing method for the workpiece lead-out hole that involves installing a closing rotating roller that grips and conveys the workpiece has also been published, but in this sealing method, the circumferential surface is made of elastic rubber with good heat and abrasion resistance. Since the rollers are made of aluminum and are provided with a pair of rotating closing rollers that are pressed against each other, they lack durability.

In other words, there are limits to elastic rubber that has good heat resistance and abrasion resistance.
It is impossible to use it for a long time in a heated state of 60° C. or higher.

The present invention has been made in view of the above, and is fixed at the fabric inlet and fabric outlet of a high-pressure steamer.
and a sealing mechanism main body in which two or more stages of decompression chambers having textile article insertion passages in the center are integrally formed so that the textile article insertion passages of each of the formed bodies communicate consistently, and the sealing mechanism main body is formed. The openings on both sides of the textile passage provided in each decompression chamber are provided with a pair of gap rolls separated by a slight gap that does not impede insertion of the textile, and further A pressure sealing device for a high-pressure steamer has been developed, which is characterized by providing a pair of drip-proof plates spaced apart from each other in each decompression chamber without interfering with the transfer of textile products.

Therefore, according to the present invention, since sealing can be performed effectively without using sealing rubber rolls that are pressed against each other, a durable sealing device can be provided.

The present invention will be explained in detail below based on embodiments shown in the drawings.

1 is a can body of a high-pressure steamer, and a textile product inlet 2 of this can body 1 is provided with a sealing device 3 described below.

This seal device 3 includes each seal block 4, 41, 4□,
43 constitutes a vertically consistent cylindrical textile product insertion passage, and partition walls 6, 6□, 6□, 63 each having a textile product insertion hole 5 between each seal block of the fabric insertion passage.
are provided, and these partition walls 6, 6□, 6□, 63 form the interior of each seal block into decompression chambers 7, 71, 72, 73.
It is formed in

8, 8□, 82 are rotatably provided above the partition walls 6, 61° 62 via the frame 9, and have a slight gap, for example, a gap of 0.2 to LO mm through which a woven or knitted fabric can pass. Each pair of metal gap rolls are arranged opposite to each other, and reference numeral 10 is a drip-proof plate of each pair located above the metal gap rolls in each vacuum chamber.

Reference numeral 11 denotes a metal gap roll which is rotatably provided outside the decompression chamber 73 via the frame 9 and is disposed oppositely with a gap of 0.2 to 10 mm as described above; and 12 is a partition wall 6.
Drip-proof plate 1 is fixed integrally with 3, 13 is the drip-proof plate 1
This is a heating means for preventing dew from adhering to the surface of 2.

Reference numeral 14 denotes a cleaning material such as felt, which is in constant contact with each metal gap roll and removes dew adhering to the surface of the metal gap roll, and 15 is an elastic material interposed between the metal gap roll and the frame 9. Seal piece, 16 is a roll end seal plate, 17 is a pressure air blowing pipe, 18 is a pressure reducing pipe,
19 is a fabric.

Next, to describe its function, the fabric 19 is introduced into the steamer can body 1 through the drip-proof spaces in the sealing device, between the metal gap rolls, and through the textile product insertion holes, 3 has four decompression chambers, and the textile product insertion hole 5 of each decompression chamber is held by a pair of metal gap rolls, etc., to a narrow gap that allows the fabric to pass through. The pressure in the room gradually decreased, and as a result of the experiment, the temperature of the steamer can was reduced to 160℃ (approximately 5ky/cri).
t), the temperature in the reduced pressure chamber 73 is about 140°C, the reduced pressure chamber 72 is about 110°C, and the reduced pressure chamber 71 is about 70°C.
At 0C, a temperature of about 30C was measured in the decompression chamber 7,
It can be seen from these measured temperatures that the pressure in each decompression chamber is decreasing sequentially.

As described above, according to the present invention, the desired seal can be achieved without using sealing rubber rolls that are pressed against each other, and each pair of metal gap rolls used in the present invention is literally made of metal as appropriate. Because it has small gaps, it has the advantage of being durable and free from wear and damage.

Furthermore, in the present invention, since the wiping material for removing dew is in contact with each metal gap roll, the dew attached to the surface of the metal gap roll is successively removed, and the drip-proof plate 12 at the lowest stage is further heated. Since the fabric is heated to prevent dew from adhering to the fabric, dew does not adhere to the fabric and the fabric is treated with good quality without uneven spots.
