Description
Technical field
The invention belongs to the supporting technical field of auxiliary facilities of optical fiber production, be specifically related to a kind of optical fiber cooling apparatus.
Background technology
Because optical fiber obtains preform (also claiming quartz glass bar) wire drawing, thus optical fiber still reaches the high temperature of about 1000 DEG C after optical fiber is shaping when coming out of the stove, so be not enough to make optical fiber be down to from the temperature of about 1000 DEG C in naturally cooling mode by the finite interval (referring to optical fiber production process) extruded and be tending towards the degree similar with envrionment temperature to the finite interval (referring to drawing process) of winder station or from fire door to outer from fire door, thus to winding or extrude outer quilt and even all can impact optical fiber surface is painted.Especially, under the prerequisite of high-speed wire-drawing, if optical fiber fast cooling can not be made in aforesaid finite interval, the carrying out of subsequent technique will certainly so be affected.Certainly, suitably slow down drawing speed and can reduce influence degree to subsequent work stations, but the production capacity in the unit time cannot improve and cause energy dissipation.
Prior art usually fire door to winding (rolling) station, at fire door to outer squeezed job contract position or arrange refrigerating unit between fire door and the painted station of optical fiber surface, this refrigerating unit is mostly a tubular body arranged inside, the outer wall of tubular body arranged inside arranges spiral coil cooling tube, in spiral coil cooling tube, pass into the heat-eliminating medium circulated, thus the optical fiber in tubular body arranged inside is cooled.But due to the air system natural air in tubular body arranged inside, and natural air belongs to oxidizing gas category, be tending towards in the process of normal temperature so make optical fiber be quickly cooled to from the high temperature of about 1000 DEG C under oxidizing gas, the quality of optical fiber can be subject to serious impact.This technical problem is puzzled in industry all the time for a long time, and expects to be solved.
" optical fibre cooling tube " that Chinese patent Authorization Notice No. CN201857349U recommends gives the enlightenment solved the problems of the technologies described above, its be one for optical fiber by way of body inwall on spiral helicine coil pipe is set, refrigerant has been passed in coil pipe, cylindrical baffle is set in the inside of coil pipe and the aperture that distributes on baffle plate, rare gas element (helium) import is offered in the mid-way of the short transverse of body, when rare gas element being introduced in body by inert gas import, rare gas element is evenly spread to baffle plate by the aperture be distributed on baffle plate under the state of the coil pipe that refrigerant is housed of nuzzling up, specifically can see the 0013rd section, the specification sheets of this patent.This patent formula objectively can embody the technique effect described in the 0010th section, its specification sheets, but there is following shortcoming: one, owing to needing the inwall laminating cylindrical baffle and the aperture that distributes in cylindrical baffle at coil pipe, thus actual making comparatively bothers; They are two years old, owing to needing optical fiber cooling apparatus to be installed on aforesaid fire door and winder station, fire door and to extrude outer by station or between fire door and the painted station of optical fiber surface under the using state of reality, thus the installation convenience for reality is an important factor overlooked either of the two, and this patent formula does not provide corresponding enlightenment; They are three years old, not only because middle part inert gas import being arranged on the cylindric body reaching four meters is arranged on 1/2nd places of the length direction of cylindric body and the rare gas element introduced by it but also need the aperture in cylindrical baffle to enter baffle plate chamber, thus for cylindric body, the quick distributing homogeneity of rare gas element is objectively subject to certain impact, and the optical fiber in baffle plate chamber still has the anxiety contacted with oxidizing gas.
