Description

Technical Field

[0001] This utility model relates to the field of optical cable production technology, specifically to an optical cable silent air dryer. Background Technology

[0002] In the production process of optical cables, the secondary extrusion process is a key step. The secondary extrusion process involves using an extrusion method to cover the optical cable with a loose tube. After the secondary extrusion process, the surface temperature of the optical cable is relatively high, so the optical cable needs to be placed in a cooling pool and cooled by cooling water.

[0003] Publication number CN221147092U discloses a fiber optic cable processing dryer that can remove waste liquid adhering to the fiber optic cable, thereby improving drying efficiency. However, during operation, the drying equipment reheats the cooled sheath. This rapid temperature change causes the sheath to become brittle, making it more susceptible to damage and breakage than the material itself. Existing air-drying equipment directly blows compressed gas onto the fiber optic cable through a pipe, which, while drying the cable, generates significant and sharp noise, causing considerable noise pollution in the production environment, affecting the health of workers and disturbing the surrounding area. Therefore, we propose a silent fiber optic cable dryer. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a silent optical cable dryer.

[0005] The technical solution adopted by this utility model to solve its technical problem is a silent optical cable dryer, including a first drying shell. A gas quick connector is fixedly connected to the side wall of the first drying shell. A circular groove is opened in the center of the first drying shell. Multiple arc-shaped air grooves are opened on the surface of the circular groove on the inner side wall of the first drying shell. The gas quick connector and the arc-shaped air grooves are connected. An air passage cover is detachably installed at one end of the first drying shell. The air passage cover, the gas quick connector and the arc-shaped air grooves form a closed air passage.

[0006] The first air-drying outer shell has a mounting groove at one end away from the air passage cover. A mounting connector is detachably installed inside the mounting groove by bolts. A silencer is fixedly connected to the side of the mounting connector away from the mounting groove. A sliding limit groove is provided inside the silencer. An air vent adjustment component is slidably connected inside the sliding limit groove. Both top ends of the air vent adjustment component are fixedly connected to limit sliders that fit into the groove inside the sliding limit groove. A threaded drive rod is rotatably installed inside the sliding limit groove. A threaded groove is provided through the bottom end of the air vent adjustment component, and the threaded drive rod passes through and is screwed into the inside of the threaded groove.

[0007] By adopting the above technical solution, when the optical cable passes through the circular groove opened in the inner wall of the first drying shell, the drying gas is allowed to enter the circular groove through the arc-shaped air groove connected to the gas quick connector by connecting the external air supply equipment to the gas quick connector, thereby drying the wet optical cable sheath surface. The arc-shaped air groove that runs through the entire interior of the first drying shell buffers and transitions the drying airflow. Then the drying airflow blows from the circular groove to the optical cable surface to quickly remove the moisture on the optical cable surface. The circular groove at one end of the first drying shell is closed by the air passage cover to prevent the airflow from being discharged from one side of the air passage cover.

[0008] After the airflow is blown into the equipment and dried, it is blocked by the air passage cover and discharged from one end of the silencer. When passing through the silencer, the airflow is discharged from the exhaust port on the surface of the silencer and the other end to filter high-frequency and ultra-high-frequency jet noise. When filtering noise, the size of the exhaust port can be adjusted according to different airflow speeds. By rotating the adjustment knob, the threaded drive rod is driven to rotate, which in turn drives the air hole adjustment component with threaded grooves to slide in the sliding limit groove under the restriction of the limit slider and the rotation of the threaded drive rod. This adjusts the size of the passage between the exhaust holes, thereby reducing noise at different frequencies within a certain range.

[0009] Specifically, the outer wall of the first air-drying shell is provided with a plurality of mounting screw holes for installation.

[0010] By adopting the above technical solution, the mounting screw holes opened on the outer wall of the first air-drying shell facilitate the quick disassembly and assembly of this equipment onto other equipment or brackets.

[0011] Specifically, an adjustment knob for adjusting the position of the air vent adjustment component is fixedly connected to the side wall of the threaded transmission rod away from the sliding limit groove.

[0012] By adopting the above technical solution, rotating the adjustment knob drives the threaded transmission rod to rotate, which in turn drives the air hole adjustment component to move within the sliding limit groove, thereby adjusting the arrangement of the holes and thus adjusting the size of the connection between the air holes.

[0013] Specifically, the vent size of the silent cylinder is the same as that of the vent adjustment component.

[0014] By adopting the above technical solution, when adjusting the position of the air hole adjustment component, the overlap of the air holes is reduced by the same size air hole displacement, and then adjustments can be made according to different equipment requirements.

[0015] Specifically, the side wall of the first air-drying outer shell is connected to the second air-drying outer shell via a connector, and the structure of the second air-drying outer shell is the same as that of the first air-drying outer shell.

[0016] By adopting the above technical solution, after closing the first and second drying outer shells, the circular grooves inside form a complete circular channel through which the optical cable passes, thereby performing the drying operation on the sheath of the optical cable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The technical solution of this application firstly involves connecting an external air supply device to a gas quick connector when the optical cable passes through a circular groove on the inner wall of the first drying outer shell. This allows the drying gas to enter the circular groove through an arc-shaped air groove connected to the gas quick connector, thereby drying the wet surface of the optical cable sheath. The arc-shaped air groove, which runs through the entire interior of the first drying outer shell, buffers and transitions the drying airflow. Subsequently, the drying airflow blows from the circular groove onto the surface of the optical cable to quickly remove the moisture from the surface of the optical cable. The circular groove at one end of the first drying outer shell is closed by an air passage cover to prevent the airflow from being discharged from one side of the air passage cover.

[0019] After the airflow is blown into the equipment and dried, it is blocked by the air passage cover and discharged from one end of the silencer. When passing through the silencer, the airflow is discharged from the exhaust port on the surface of the silencer and the other end to filter high-frequency and ultra-high-frequency jet noise. When filtering noise, the size of the exhaust port can be adjusted according to different airflow speeds. By rotating the adjustment knob, the threaded drive rod is driven to rotate, which in turn drives the air hole adjustment component with threaded grooves to slide in the sliding limit groove under the restriction of the limit slider and the rotation of the threaded drive rod. This adjusts the size of the passage between the exhaust holes, thereby reducing noise at different frequencies within a certain range. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a silent optical cable dryer, including a first drying shell 1, a gas quick connector 7 is fixedly connected to the side wall of the first drying shell 1, a circular groove 6 is opened in the center of the first drying shell 1, a plurality of arc-shaped air grooves 15 are opened on the surface of the circular groove 6 on the inner side wall of the first drying shell 1, and the gas quick connector 7 and the arc-shaped air grooves 15 are connected, and an air passage cover plate 5 is detachably installed at one end of the first drying shell 1, and the air passage cover plate 5, the gas quick connector 7 and the arc-shaped air grooves 15 form a closed air passage;

[0028] The first air-drying outer shell 1 has an installation groove 2 at the end away from the air passage cover plate 5. An installation connector 3 is detachably installed inside the installation groove 2 by bolts. A silencer 4 is fixedly connected to the side of the installation connector 3 away from the installation groove 2. A sliding limit groove 8 is opened inside the silencer 4. An air hole adjustment component 9 is slidably connected inside the sliding limit groove 8. Both top ends of the air hole adjustment component 9 are fixedly connected to a limit slider 10 that matches the groove inside the sliding limit groove 8. A threaded transmission rod 11 is rotatably installed inside the sliding limit groove 8. A threaded groove 13 is opened through the bottom end of the air hole adjustment component 9, and the threaded transmission rod 11 passes through and is screwed into the inside of the threaded groove 13.

[0029] In use, when the optical cable passes through the circular groove 6 opened in the inner wall of the first drying outer shell 1, the drying gas is introduced into the circular groove 6 through the arc-shaped air groove 15 connected to the gas quick connector 7 by connecting the external air supply device to the gas quick connector 7. This allows the drying gas to be introduced into the circular groove 6, thereby drying the wet surface of the optical cable sheath. The arc-shaped air groove 15, which runs through the entire interior of the first drying outer shell 1, buffers and transitions the drying airflow. Then, the drying airflow blows from the circular groove 6 to the surface of the optical cable to quickly remove the moisture from the surface of the optical cable. The circular groove 6 at one end of the first drying outer shell 1 is closed by the air passage cover plate 5 to prevent the airflow from being discharged from one side of the air passage cover plate 5.

[0030] After the airflow is blown into the equipment and dried, it is blocked by the air passage cover plate 5 and discharged through one end of the silencer 4. When passing through the silencer 4, the airflow is discharged from the exhaust hole on the surface of the silencer 4 and the other end to filter high-frequency and ultra-high-frequency jet noise. When filtering noise, the size of the exhaust hole can be adjusted according to different airflow speeds. By rotating the adjustment knob 12, the threaded transmission rod 11 is driven to rotate, thereby driving the air hole adjustment component 9 with the threaded groove 13 to slide in the sliding limit groove 8 under the restriction of the limit slider 10 and the rotation of the threaded transmission rod 11, thereby adjusting the size of the passage between the exhaust holes, thereby reducing noise for different frequencies within a certain range.

[0031] As shown in the figure, the outer side wall of the first air-drying shell 1 is provided with a plurality of mounting screw holes 14 for installation.

[0032] When in use, the mounting screw holes 14 on the outer wall of the first drying housing 1 facilitate quick disassembly and assembly of this equipment onto other equipment or brackets.

[0033] As shown in the figure, an adjustment knob 12 for adjusting the position of the air hole adjustment component 9 is fixedly connected to the side wall of the threaded transmission rod 11 away from the sliding limit groove 8.

[0034] In use, rotating the adjustment knob 12 drives the threaded transmission rod 11 to rotate, which in turn drives the air hole adjustment component 9 to move within the sliding limit groove 8, thereby adjusting the arrangement of the holes and thus adjusting the size of the connection between the air holes.

[0035] As shown in the figure, the air holes of the silent cylinder 4 and the air hole adjustment component 9 are the same size.

[0036] When using the air vent adjustment component 9, the overlap of the air vents is reduced by adjusting the air vent displacement of the same size, and then adjusted according to different equipment requirements.

[0037] As shown in the figure, the side wall of the first air-drying outer shell 1 is connected to the second air-drying outer shell 16 by a connector, and the structure of the second air-drying outer shell 16 is the same as that of the first air-drying outer shell 1.

[0038] In use, after closing the first drying outer shell 1 and the second drying outer shell 16, the circular groove 6 opened inside forms a complete circular channel to pass through the optical cable, thereby performing the drying operation on the sheath of the optical cable.

[0039] The working principle and usage process of this utility model are as follows: After closing the first drying outer shell 1 and the second drying outer shell 16, the circular groove 6 inside forms a complete circular channel for the optical cable to pass through, thereby drying the optical cable sheath. The mounting screw holes 14 on the outer wall of the first drying outer shell 1 facilitate quick disassembly and assembly of this device onto other equipment or brackets. During use, when the optical cable passes through the circular groove 6 on the inner wall of the first drying outer shell 1, the drying gas is introduced into the circular groove 6 through the arc-shaped air groove 15 connected to the gas quick connector 7 by connecting an external air supply device. This allows the drying gas to enter the circular groove 6, thereby drying the damp optical cable sheath surface. The arc-shaped air groove 15, which runs through the entire interior of the first drying outer shell 1, buffers and transitions the drying airflow. Subsequently, the drying airflow blows from the circular groove 6 onto the optical cable surface to quickly remove moisture. The air passage cover 5 closes the circular groove 6 at one end of the first drying outer shell 1, preventing the airflow from escaping from one side of the air passage cover 5. After the airflow is blown into the equipment and dried, it is blocked by the air passage cover plate 5 and discharged through one end of the silencer 4. When passing through the silencer 4, the airflow is discharged from the exhaust port on the surface of the silencer 4 and the other end to filter high-frequency and ultra-high-frequency jet noise. When filtering noise, the size of the exhaust port can be adjusted according to different airflow speeds. By rotating the adjustment knob 12, the threaded transmission rod 11 is driven to rotate, thereby driving the air hole adjustment component 9 with the threaded groove 13 to slide in the sliding limit groove 8 under the restriction of the limit slider 10 and the rotation of the threaded transmission rod 11. This adjusts the size of the connection between the exhaust holes, thereby reducing noise at different frequencies within a certain range. Rotating the adjustment knob 12 drives the threaded transmission rod 11 to rotate, thereby driving the air hole adjustment component 9 to move in the sliding limit groove 8 to adjust the arrangement of the holes and adjust the size of the connection between the air holes. By moving the air holes of the same size, the overlap of the air holes is reduced. Adjustments can be made according to different equipment requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
