Abstract
The utility model provides a gas protector of optical-fiber curing furnace. An inlet and an outlet of the optical fiber are separately provided with diaphragm which can adjust size; the lower part of the outlet of the optical fiber is provided with a wind suction shield; through adjusting diaphragm of the device and using the wind suction shield, oxidation content among air can be decreased to enter the optical-fiber curing furnace and control furnace, a volatile object can be timely drained from the furnace under high temperature and curing quality of the optical fiber is improved.
Description
Technical field
The utility model relates to a kind of device, the especially gas shield device of producing in the fiber plant of optical fiber curing stove.
Background technology
The existing fiber curing oven influences optical fiber quality for preventing that air enters in the optical fiber curing in the stove, employing reduces entering of air to the method for inflated with nitrogen in the stove, because the optical fiber of fire door inlet size can't be regulated, entering of air is difficult to control, the optical fiber of furnace bottom outlet size also can't be regulated in addition, cause oxygen level in the stove to be difficult to control and volatile matter that furnace high-temperature produces down is difficult to discharge, thereby make optical fiber curing bad.
Summary of the invention
In order to solve the existing problem of existing fiber curing oven; the utility model provides a kind of optical fiber curing furnace gases protective device; the optical fiber inlet of its fire door and the optical fiber outlet size of furnace bottom can be regulated; the volatile matter that furnace high-temperature produces is down discharged easily; make entering in the minimizing, stove oxygen level and can controlling of furnace air; remove the volatile matter that produces under the furnace high-temperature as early as possible, thereby improve the optical fiber curing quality.
The optical fiber curing furnace gases protective device that the utility model provides; optical fiber porch and exit at optical fiber curing stove (4) are provided with respectively and can regulate big or small diaphragm (1) and (2) by diaphragm adjustable plate (5), and suspended hood (3) is set below the optical fiber exit.
The beneficial effects of the utility model are: during optical fiber curing stove (4) work, by regulating diaphragm (1), can further reduce air and enter in the stove; Regulate diaphragm (2) and can control the oxygen level of optical fiber curing stove (4), reduce influence optical fiber curing; The volatile matter that the suspended hood (3) that below, optical fiber exit is provided with can in time produce furnace high-temperature is down discharged, and reduces volatile matter and is attracted to optical fiber surface, improves the optical fiber curing quality.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model, and Fig. 2 is that A among Fig. 1 is to view.
In Fig. 1, Fig. 2,1,2. diaphragm, 3. suspended hood, 4. optical fiber curing stove, 5. diaphragm adjustable plate, 6. diaphragm adjustable plate turning axle, 7. lock screw.
Embodiment
In Fig. 1, among Fig. 2, diaphragm (1) is identical with the structure of (2), and the adjustable plate (5) that all use two one sideband semicircle orifices, can rotate around turning axle (6) separately constitutes, and is regulating the back, location with lock screw (7) locking.The external air exhauster of suspended hood (3), the volatile matter that can in time furnace high-temperature be produced down siphons away.
Claims (1)
1, a kind of optical fiber curing furnace gases protective device is characterized in that the diaphragm that the scalable size is set in the optical fiber porch and the exit of optical fiber curing stove respectively below the optical fiber exit suspended hood being set.
