Abstract

The invention relates to a method and device for continuously treating synthetic fibers in a heat exchange chamber, in which the fiber to be treated comes into direct contact with the heat exchange medium. A sealing device, which is subjected to the action of a sealing medium, which is provided at the fiber exit opening and at the fiber entry opening with a supply line for the sealing medium, which is arranged in the proximity of the fiber exit opening or the fiber entry opening. The sealing medium is kept away from the fiber passing through the heat exchange chamber. This is achieved by removing the sealing medium before the heat exchange chamber or also by removing the heat exchange medium together with the sealing medium. A removal line for the sealing medium is arranged in the proximity of the heat exchange chamber. In addition, the heat exchanger is provided in a separable manner so that the fiber can inserted by removing one part.

Independent Claims | See all claims (26)

1. 1. A method for the sealing of a heat exchanger for the continuous treatment of synthetic threads in a heat exchange chamber, in which the thread to be treated comes into direct contact with the heat exchange medium, and which heat exchange chamber possesses a thread exit opening and a thread entry opening, on which said chamber, is provided a sealing apparatus, which is supplied with a sealing medium, and said sealing apparatus has a feed line for the said sealing medium placed proximal to the said openings for thread exit and entry, therein characterized, in that the sealing medium is distanced from the thread running through the heat exchange chamber.
2. 4. A method in accord with one or more of the foregoing Claims, therein characterized, in that the removal of the heat exchange medium is carried out together with the removal of the sealing medium.
3. 5. A method in accord with one or more of the foregoing Claims, therein characterized, in that the heat exchange medium, together with the sealing medium is removed, treated, and the heat exchange medium is recycled in the heat exchanger (1).
4. 7. A method in accord with one or more of the foregoing Claims, therein characterized, in that the heat exchange medium flowing through the heat exchange chamber (1) is directed within the said heat exchange chamber (100) against the thread (F), in order to increase the direct contact of the thread with the heat exchange medium.
5. 8. A method in accord with one or more of the foregoing Claims, therein characterized, in that the course of travel of the thread intersects the surface level of the cooling medium.
6. 10. A method in accord with one or more of the foregoing Claims, therein characterized, in that, in the case of a predominately vertical placement of the heat exchanger, the thread travels from above to below.
7. 11. A heat exchanger for the continuous treatment of synthetic threads in a heat exchange chamber (1, 10), in which the thread (F) to be treated comes into direct contact with the heat exchange medium, and which said heat exchange chamber possesses a thread exit opening (11) and a thread entry opening (12), and has a sealing apparatus (2) supplied with a sealing medium, and said sealing apparatus (2) has a feed line (21) for the said sealing medium placed proximal to the thread exit opening and to the thread entry opening, therein characterized, in that, proximal to the heat exchange chamber (1, 10), is placed an exit line (22; 25, 25′) for the sealing medium.
8. 15. A heat exchanger for the continuous treatment of synthetic threads in a heat exchange chamber (1, 10), in which the thread to be treated (F) comes into direct contact with a heat exchange medium and said heat exchange chamber possesses a thread exit opening (11) and a thread entry opening (12), on which, respectively, a sealing apparatus (2) supplied with a sealing medium is provided, having an inflow line (21) for the sealing medium placed respectively near the thread exit opening and the thread inlet opening, therein characterized, in that proximal to the respective thread passage openings (11; 12) within the heat exchange chamber, diversion vanes (13) are placed, said diversion vanes (13) having a small opening for the thread (F), so that sealing medium penetrating through the thread openings (11; 12) is held distant from the thread (F).
9. 17. A heat exchanger for the continuous treatment of synthetic threads in a heat exchange chamber (1, 10), in which the thread to be treated (F) comes into direct contact with the heat exchange medium and which heat exchanger possesses a thread exit opening (11) and a thread entry opening (12), on each, respectively, a sealing apparatus is provided supplied with a sealing medium, said sealing medium having an inflow line (21) placed near the openings for thread exit and thread inlet, therein characterized, in that the heat exchange chamber (100) exhibits a narrow passage (19) centrally aligned with the thread (F) and the inlet line (15) and the outlet line (16) of the heat exchange medium is so placed before or after the narrow passage (19), that the said narrow passage (19) allows a flow of the heat exchange medium to be counter to the direction of travel of the thread (F).
