Description

Technical Field

[0001] The utility model belongs to the technical field of optical cable processing supporting facility design, in particular to an optical cable sheath drying device. Background Art

[0002] Fiber optic cable is a type of cable used to transmit optical signals. It is widely used in communications networks, the internet, cable television, medical equipment, military, and aerospace applications. During the production process, after the cable is sheathed in an extruder, its surface temperature reaches a very high temperature, requiring cooling in a water tank. The cable sheath exits the water tank carrying a large amount of water droplets and vapor. To ensure the integrity and durability of the printed text on the cable, the moisture on the cable surface must be dried quickly.

[0003] Existing optical cable drying devices lack a step for processing the blown-out water vapor. In a humid environment, the water vapor easily flows back into the blowing sleeve, affecting the dehumidification result. At the same time, this part of the water vapor cannot be recycled, resulting in a waste of resources. Utility Model Content

[0007] Furthermore: the box device includes a dehumidification box, a plurality of partitions are evenly and fixedly arranged in the middle of the dehumidification box, and insulation pipes are fixedly arranged on the partitions.

[0008] Furthermore: the dehumidification device includes a blowing sleeve, two air inlet valves are symmetrically arranged on the upper and lower sides of the blowing sleeve, a number of horizontal air inlet holes are evenly arranged in the middle of the blowing sleeve, vertical air inlet holes are arranged above the horizontal air inlet holes, and a number of air outlet holes are evenly arranged on one side of the blowing sleeve.

[0009] Furthermore, the connecting pipe and the air inlet valve are connected together through a joint, and the blowing sleeve is bolted to the heating box.

[0010] Furthermore: the top plate is connected to the dehumidification box bearing, the heat dissipation grille is square-shaped, and the heat dissipation grille and the heat dissipation block are integrally formed.

[0011] Furthermore: the bottom surface of the top plate is arc-shaped, and the cross-section of the receiving piece is V-shaped.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting a heating block at the bottom of the dehumidification box, the internal temperature of the dehumidification box is increased, which promotes the evaporation of water vapor on the air outlet and prevents it from flowing back into the blowing sleeve when not spraying, which will affect the dehumidification result.

[0014] By providing a receiving plate on the top plate with a curved bottom surface and cooperating with the heating block to evaporate water vapor, the water vapor can be recovered at the top plate, which not only solves the problem of excess water vapor, but also saves costs, avoids moisture in the processing site, and improves the practicality of the device.
