[0015] This utility model discloses a drying device for flame-retardant insulation material of communication cable. Through the setting of air distribution cavity and air inlet, the drying hot air can enter the drying chamber evenly from the bottom and pass through the gaps between the insulation materials from bottom to top, so that all parts of the flame-retardant insulation material of the communication cable can come into contact with the hot air, thereby achieving uniform drying and avoiding the situation of incomplete drying in some areas.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-5 This utility model provides a drying device for flame-retardant insulation material of communication cable, including a support 1. The bottom of the support 1 is provided with an extension platform with holes, which can facilitate the positioning of the support 1.

[0027] Furthermore, a drying chamber 2 is fixed on the upper side of the support 1, a sliding door 4 is installed at the bottom of the drying chamber 2, a groove 24 is opened on one side of the bottom of the drying chamber 2, the sliding door 4 is slidably embedded in the groove 24, and a handrail 41 is fixedly connected to one side end face of the sliding door 4.

[0028] Specifically, during use, the operator pours the flame-retardant insulation material of the communication cable into the drying chamber 2 through the feed inlet 5. During the drying process, the sliding door 4 remains closed to ensure that the hot air in the drying chamber 2 does not leak. When the insulation material is dried, the operator holds the handle 41 and pulls the sliding door 4 outward to make it slide along the slide groove 24 and open. At this time, the dried insulation material is discharged from the opening at the bottom of the drying chamber 2 under the action of gravity and enters the discharge frame 12 to complete the discharge operation.

[0029] Furthermore, a discharge port 11 is provided on one side of the support 1, and an inclined discharge frame 12 is fixedly connected between the bottom wall of the discharge port 11 and the inner wall of the other side of the support 1.

[0030] Specifically, the upper end of the discharge frame 12 is vertically aligned with the bottom opening of the drying chamber 2, and the lower end extends to the discharge port 11 on the outside of the support 1. The 30° inclined design utilizes gravity to allow the insulating material to slide smoothly, reducing the risk of blockage by 70-90% compared to the traditional horizontal discharge structure, and requiring no additional power. The inner wall of the discharge frame is equipped with high anti-slip ridges to ensure that the material does not slip and leaves no residue during the sliding process.

[0031] Furthermore, a stirring assembly 3 is installed inside the drying chamber 2. A feed inlet 5 and an exhaust assembly 6 are installed on the top of the drying chamber 2. The stirring assembly 3 includes a rotating shaft 31 that is rotatably embedded between the two end faces of the drying chamber 2 and a drive motor 32 that is fixedly connected to the outer wall of one side of the drying chamber 2. The output end of the drive motor 32 is fixedly connected to the rotating shaft 31. Multiple connecting rings 33 are fixedly sleeved on the outer side of the rotating shaft 31. Multiple stirring blades 34 are equidistantly arranged on the outer peripheral wall of the connecting rings 33.

[0032] Specifically, during use, the drive motor 32 is started, and the output end of the drive motor 32 drives the rotating shaft 31 to rotate, which in turn drives the connecting ring 33 and the stirring blade 34 to rotate. During the rotation, the stirring blade 34 continuously tumbles the insulating material, so that all parts of the insulating material can be evenly contacted by the hot air, thereby achieving uniform drying and ensuring that the insulating material can be dried evenly and efficiently.

[0033] Furthermore, the exhaust assembly 6 includes an air distribution plate 61 fixedly embedded between the top inner walls of the drying chamber 2 and an exhaust pipe 62 fixedly embedded on the top wall of the drying chamber 2, and the air distribution plate 61 is provided with a plurality of exhaust holes 63.

[0034] Specifically, the hot and humid air generated during the drying process is evenly guided by the air distribution plate 61 and then discharged through the exhaust pipe 62 at a flow rate of 0.5-0.8 m / s in a swirling motion. This structure improves the moisture discharge efficiency by 20-40% compared to the traditional non-guided exhaust method, greatly shortens the residence time of hot and humid air in the chamber, and effectively avoids the accumulation of local condensate.

[0035] Furthermore, the air distribution plate 61 is fixedly embedded with a feed inlet 5, the top of the feed inlet 5 is disposed through the top wall of the drying chamber 2, and the top of the feed inlet 5 is threadedly connected to an end cap 51.

[0036] Specifically, the operator can open the end cover 51 and pour the flame-retardant insulation material of the communication cable into the drying chamber 2 through the feed inlet 5. After pouring in the insulation material, the end cover 51 can be closed to ensure the sealing of the feed inlet 5.

[0037] Furthermore, air distribution cavities 21 are provided on the bottom wall of the drying chamber 2 and on both sides of the sliding door 4, and multiple air inlets 22 are densely arranged on the side of the air distribution cavities 21 facing the interior space of the drying chamber 2. Air inlet pipes 23 are fixedly embedded on both sides of the drying chamber 2, and the air inlet pipes 23 are all connected to the adjacent air distribution cavities 21.

[0038] Specifically, the air pump draws dry hot air and introduces it into the air distribution cavity 21 through the air inlet pipe 23. The hot air in the air distribution cavity 21 enters the drying chamber 2 evenly through the air inlet 22 and passes through the gaps between the insulating materials from bottom to top. As the hot air passes through the insulating materials, it carries away the moisture on the surface of the insulating materials, achieving the drying effect. Finally, the hot air is discharged from the drying chamber 2 through the exhaust assembly 6.

[0039] Specifically, a sliding bar is provided on each side of the sliding door 4, and a guide groove is provided on each side of the sliding groove 24 corresponding to the sliding bar. The sliding bar can slide along the guide groove, so that the sliding door 4 can be opened or closed. It is worth noting that the bottom of the drying chamber 2 has a semi-circular structure. The radius of the semi-circular structure is basically the same as the length of the stirring blade 34, and the upper side of the sliding door 4 can be flush with the bottom of the drying chamber 2, so there is no dead corner for stirring, thus ensuring that the insulating material can be stirred fully.

[0040] Working principle: When in use, the flame-retardant insulation material of the communication cable is poured into the drying chamber 2 through the feed port 5. The drive motor 32 is started, which drives the rotating shaft 31 and the connecting ring 33 to rotate, so that the stirring blades 34 continuously stir the insulation material at the bottom of the drying chamber 2. The air pump draws dry hot air into the air distribution cavity 21 through the air inlet pipe 23, so that the hot air can enter the drying chamber 2 through each air inlet 22. At the same time, the hot air passes through the flame-retardant insulation material of the communication cable from bottom to top, through the exhaust port 63 and the exhaust pipe 62, which can remove the moisture on the surface of the flame-retardant insulation material of the communication cable, effectively drying the flame-retardant insulation material of the communication cable. After the flame-retardant insulation material of the communication cable is dried, hold the handle 41 and pull the sliding door 4 outward, so that the flame-retardant insulation material of the communication cable inside the drying chamber 2 can fall into the discharge frame 12 for discharge.
