Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a high-pressure steamer used for moist heat treatment of fabrics, and a method for sealing the steamer can body and each of the fabric inlet and outlet of the steamer can so that the fabric can be inserted. This invention relates to a high-pressure steamer with an improved connection to a sealing mechanism.

High-pressure steamers are already known for applying high-temperature, high-pressure saturated steam to textile products such as fabrics and threads to subject them to high-temperature, high-pressure, moist heat treatment. The inventor has spent a long period of time researching a sealing mechanism for continuously introducing textiles into the steamer or leading them out of the steamer.
We have also completed numerous applications regarding the sealing device.

However, the high-pressure steamers equipped with previously developed sealing mechanisms have the sealing mechanisms installed at the top of the horizontal cylindrical high-pressure steamer can, which increases the overall height of the steamer. was.

For example, in the previous high-pressure steamer, the height of the can body was approximately 3 m, and the height of the sealing device was approximately 1 m, so the overall height was approximately 4 m, and the height of the building was accordingly increased. Furthermore, there was the inconvenience of having to perform work such as repairing the seal mechanism at a high place.

In order to eliminate this inconvenience, we have proposed a high-pressure steamer in which sealing mechanisms are attached to both lower sides of the steamer can.

Furthermore, to describe this high-pressure steamer in detail based on FIG. The inlet seal mechanism and the outlet seal mechanism E were directly fixed to the outlet C via flanges b and C.

In this high-pressure steamer, if the internal pressure of the steamer can body A is increased above normal pressure, the internal pressure and expansion force will cause distortion in the can body A, but the distortion of the steamer can body A is due to its shape. Since the degree of distortion is different between the upper side of the can body A and the lower side having the pace a, the flanges b and C at the edges of the fabric inlet B and the fabric outlet C lose their perpendicularity, and are shown by chain lines. This causes a tilt.

This inclination, or strain, is transmitted to the sealing mechanism and E, causing a change in the contact pressure between the sealing rolls d and e of the sealing mechanism, which may result in no longer being able to seal effectively, or may impede the drive of both sealing rolls. There was a problem that occurred.

The present invention was made to solve this problem, and the steamer can body and the sealing mechanism are connected through a flexible plate material, and the strain occurring in the steamer can body is absorbed by the flexible plate material. It provides a high-pressure steamer designed to absorb water.

The present invention will be explained in detail below based on the embodiment shown in FIG.

Reference numeral 1 denotes a steamer can body for treating fabric under high pressure and moist heat, and this steamer can body 1 is provided with a fabric inlet 2 and a fabric outlet 3, and further includes a fabric inlet 20.
A flange 2' is formed on the outer edge, and a flange 3' is formed on the edge of the fabric outlet 3.

Reference numeral 4 denotes an inlet-side sealing mechanism attached to the fabric inlet 2, and 5 denotes an outlet-side sealing mechanism attached to the fabric outlet 3. These sealing mechanisms maintain high pressure moist heat in the high pressure steamer can body 1. However, the introduction-side sealing mechanism 4 is provided to allow the fabric to be introduced and taken out, and the introduction-side seal mechanism 4 connects the fabric introduction port 2 to a frame 7 having a flange 6 having an inner diameter smaller than the outer diameter of the flange 2'. Leading fabric insertion passage 8
A pair of seal rubber rolls 9 are pressed against each other to close the outer opening of the fabric insertion passage 8, and a part of the fabric insertion passage is formed in the liquid seal tank 10.

Further, the outlet side sealing mechanism 5 includes a frame 12 having a flange 11 having an inner diameter smaller than the outer diameter of the flange 3', and a fabric insertion passage 13 that communicates with the fabric outlet 3, and a fabric insertion passage 13 of the fabric insertion passage 13. A pair of seal rubber rolls 14 are pressed against each other to close the outer opening, and a part of the fabric insertion passage is formed in an annealing tank 15.

Reference numeral 16 denotes a flexible plate material whose inner peripheral edge is closely attached to the flange 2' of the fabric inlet 2 and whose outer peripheral edge is closely attached to the 7 flange 6 of the frame 7, and 17 is a flexible plate whose inner circumferential edge is closely attached to the flange 3 of the fabric outlet 3. ', and the outer peripheral edge is the flange 1 of the frame 12.
1, these flexible plates 16 and 17 are flexible and have sufficient strength to withstand the internal pressure inside the steamer can, for example, around 3 kg/crt1. For example, it is formed of a metal plate, a synthetic rubber plate, or the like.

Reference numeral 18 denotes a base, on which the steamer can 1, the inlet seal mechanism 4, and the outlet seal mechanism 5 are supported via a support stand 19.

The above is the structure of this embodiment. As is clear from the above embodiments, the present invention has a fabric inlet that can continuously supply fabric and a fabric outlet that can continuously draw out fabric. In a high-pressure steamer having a steamer can body, an inlet-side sealing mechanism provided at the fabric inlet of the steamer can, and an outlet-side sealing mechanism similarly provided at the fabric outlet, the fabric inlet of the steamer can and the fabric Since this is a high-pressure steamer in which an inlet-side seal mechanism and an outlet-side seal mechanism are connected to each of the outlet ports through a flexible plate material that can absorb strain occurring in the steamer can body, the high-pressure steamer according to the present invention Distortion of the steamer can caused by sending high-pressure moist heat into the can is absorbed by the flexible plate material, and the distortion is not transmitted to both sealing mechanisms.

Therefore, according to the present invention, there is a feature that a stable and effective seal can be maintained since no distortion is caused in the sealing mechanism.
