Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of optical fiber production, specifically to a cooling device for optical fiber production. BACKGROUND

[0002] Optical fiber is the abbreviation of optical waveguide fiber, which is a kind of fiber made of glass or plastic and can be used as an optical transmission tool. The transmission principle is total reflection of light. The fine optical fiber is packaged in a plastic sheath, so that it can be bent without breaking. Usually, the transmitting device at one end of the optical fiber uses a light emitting diode (LED) or a bundle of laser to transmit light pulses to the optical fiber, and the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses. In daily life, because the transmission loss of light in optical waveguide fiber is much lower than that of electricity in wire transmission, optical fiber is used for long-distance information transmission.

However, this cooling method is relatively slow, and is suitable for small-scale experiments or situations where the cooling speed is not high. In large-scale production, the efficiency of natural cooling is low, which reduces the efficiency of production and detection. Therefore, a cooling device for optical fiber production is proposed.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a cooling device for optical fiber production, including frame 1, the top of frame 1 is fixedly installed with several hollow support cylinders 7, the bottom of the inner cavity of hollow support cylinder 7 is provided with several backflow holes 22, the inner side wall of the top of hollow support cylinder 7 is provided with several communication holes one 8, the outer side wall of hollow support cylinder 7 is fixedly penetrated and is provided with several cooling strip one 9, the top of frame 1 is fixedly installed with four slide bars 3, the outer side of four slide bars 3 is movably sleeved with first hollow plate 4, the bottom of first hollow plate 4 is fixedly installed with several cylinder plugs 11, the top of cylinder plug 11 is communicated with flow guide pipe 10, the opposite end of flow guide pipe 10 is communicated with communication cylinder 12, the middle part of the bottom of communication cylinder 12 is communicated with connecting pipe 16, the bottom end of connecting pipe 16 is communicated with flow guide flexible hose 15, the bottom end of flow guide flexible hose 15 is communicated with circulating pump 14, the input end of circulating pump 14 is communicated with water suction pipe 13, the outer side of cylinder plug 11 is movably sleeved with two sealing rings 20 by recess, the side wall of cylinder plug 11 is provided with several communication holes two 21, the side wall of cylinder plug 11 is fixedly penetrated and is installed with several cooling strip two 17, the inside of cylinder plug 11 is fixedly sleeved with pressure relief pipe 18, the inside of the top of pressure relief pipe 18 is movably installed with electric control valve 19, the outer side of four slide bars 3 is slidably installed with second hollow plate 5, the top of second hollow plate 5 is movably installed with two cooling fans 6, one side of frame 1 is communicated with discharge pipe 2.

[0020] The working principle of the above technical scheme is as follows: in use, the user puts the optical fiber preform to be cooled into the inside of the hollow supporting cylinder 7, and moves the cylinder plug 11 downward through the first hollow plate 4, so that the cylinder plug 11 covers the inside of the top end of the hollow supporting cylinder 7. At this time, the communication hole one 8 and the communication hole two 21 correspond, and the sealing ring 20 seals the joint between the cylinder plug 11 and the hollow supporting cylinder 7. Then, the cooling fan 6 and the circulating pump 14 are started. After the circulating pump 14 is started, the cooling liquid in the frame body 1 is pumped out through the water suction pipe 13, and is introduced into the inside of the communication cylinder 12 through the flow guide flexible hose 15 and the connecting pipe 16. The liquid is divided by the communication cylinder 12 and enters the inside of the flow guide pipe 10. Then, the liquid enters the inside of the cylinder plug 11 through the flow guide pipe 10. At this time, the cylinder plug 11 guides the liquid to flow through the communication hole two 21 and the communication hole one 8, so that the cooling liquid enters the inside of the hollow supporting cylinder 7 through the communication hole one 8, and flows in the hollow supporting cylinder 7 by gravity. Finally, the cooling liquid flows back to the inside of the frame body 1 through the backflow hole 22, realizing cooling circulation. At the same time, the cooling fan 6 starts to accelerate the airflow through the heat dissipation strip two 17 and the heat dissipation strip one 9, and dissipates the temperature of the cooling liquid discharged by the heat dissipation strip two 17 and the heat dissipation strip one 9, so that the cooling liquid is evenly cooled, the temperature of the cooling liquid is relatively stable, the cooling liquid forms an internal circulation, the cooling efficiency is improved, and the cooling is uniform and stable.

[0021] In another embodiment, as shown in Figures 1-4 The hollow supporting cylinder 7 is linearly and uniformly distributed in the top of the frame body 1, and the cylinder plug 11 is linearly and uniformly distributed in the bottom of the first hollow plate 4. The size of the cylinder plug 11 is matched with the size of the hollow supporting cylinder 7.

[0022] The cylinder plug 11 covers the top end of the hollow supporting cylinder 7, seals the top end of the hollow supporting cylinder 7, and contacts the bottom end of the cylinder plug 11 with the optical fiber preform, so that the top end of the optical fiber preform is also cooled while improving the cooling efficiency, and the top end of the optical fiber preform is blocked, realizing closed cooling effect, avoiding dust pollution of the optical fiber preform in the air, increasing the protection effect, and indirectly improving the production efficiency and quality.

[0023] In another embodiment, as shown in Figures 1-4 The backflow hole 22 is uniformly distributed in the bottom of the hollow supporting cylinder 7, and extends to the top of the inner cavity of the frame body 1. The connecting pipe 16 extends through the first hollow plate 4 and extends to the bottom of the first hollow plate 4. The circulating pump 14 is fixedly installed on the top of the frame body 1. The water suction pipe 13 extends through the frame body 1 and is connected to the bottom of the inner cavity of the frame body 1.

[0024] The return hole 22 guides the coolant flowing through the hollow interlayer of the hollow support cylinder 7 back to the interior of the frame 1. The water intake pipe 13 facilitates the circulation pump 14 to extract the coolant, which is then introduced into the interior of the connecting cylinder 12 through the guide telescopic hose 15 and the connecting pipe 16 to form a coolant circulation.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the first connecting hole 8 is evenly distributed in a circle on the inner side wall of the top of the hollow support cylinder 7, and the second connecting hole 21 is evenly distributed in a circle on the side wall of the cylinder plug 11. The specifications and dimensions of the first connecting hole 8 and the second connecting hole 21 are compatible. The two sealing rings 20 are located at the top and bottom of the second connecting hole 21, respectively.

[0026] The connecting hole 8 and the connecting hole 21 correspond to each other and are sealed by the sealing ring 20 at the top and bottom, which promotes the coolant to enter the interior of the hollow support cylinder 7, forming a coolant flow, which facilitates the enveloping flow into the interior of the hollow support cylinder 7 and increases the uniformity of the flow.

[0027] In another implementation scheme, such as Figures 1-4 As shown, heat dissipation strip 19 is evenly distributed in a circle on the outer wall of the hollow support cylinder 7. Heat dissipation strip 19 is fixedly inserted through the hollow support cylinder 7 and extends to the outer side of the hollow support cylinder 7. Heat dissipation strip 217 is evenly distributed in a circle inside the cylinder plug 11. Heat dissipation strip 217 is fixedly inserted through the cylinder plug 11 and extends to the outer side of the cylinder plug 11.

[0028] One end of heat sink 9 and the other end of heat sink 17 are in contact with the coolant, while the other end extends to the outside. By using the airflow from the outside, the heat dissipation area is increased, and the heat dissipation effect is enhanced, thereby achieving stable and balanced heat dissipation, which is beneficial for heat dissipation.

[0029] In another implementation scheme, such as Figures 1-4 As shown, the bottom end of the pressure relief pipe 18 is connected to the bottom of the plug 11. The pressure relief pipe 18 is fixedly inserted through the plug 11 and extends to the top of the first hollow plate 4. A valve is installed inside the discharge pipe 2.

[0030] When the pressure relief pipe 18 is used, a low-pressure area is formed inside the hollow support cylinder 7 after the optical fiber preform is cooled. At this time, the electrically controlled valve 19 is opened to release pressure on the opposite side of the cylinder plug 11 and the hollow support cylinder 7 through the pressure relief pipe 18, thereby assisting in opening the structure. The valve inside the discharge pipe 2 is opened to allow the coolant inside the frame 1 to be replaced and maintained regularly for easy use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
