[0002] During the production process of electric wires, after the electric wires are extruded and wrapped around the wire core, they need to be cooled with water. After water cooling, water will remain on the insulating rubber of the electric wires, and the electric wires cannot be used or stored directly. Drying equipment is needed to dry the water on the wire rubber before use or storage. Existing equipment uses electric heating to achieve the drying effect, but existing equipment generally has problems such as short time for the wires to pass through the drying equipment, low drying efficiency, large energy loss, and heat cannot be recovered, which leads to the inability to completely dry the wires.

However, the ventilation fan and exhaust pipe of the device will discharge the hot air in the drying room to the outside of the device, resulting in the inability to reach the ideal drying temperature in the drying room, and the energy loss is large, and the drying efficiency is low.

[0004] Based on this, the technical problem solved in this case is: how to solve the problems of short drying time, low drying efficiency, high energy loss and insufficient utilization of heat of the drying equipment. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Example 1

[0015] See also Figures 1 to 3 A wire drying device comprises a box body 1, and a guide roller group 2 arranged in the box body 1 for pulling the wire. The box body 1 is composed of an outer shell 11 and an inner shell 12, and the inner shell 12 forms a closed drying chamber 121, and a closed ventilation chamber 13 is formed between the outer shell 11 and the inner shell 12; the outer shell 11 is provided with an air inlet 3 and a return air outlet 4 connected to the ventilation chamber 13; the inner shell 12 is provided with an air outlet 5 connecting the drying chamber 121 and the ventilation chamber 13; the inner shell 12 is also provided with an exhaust port 6 for discharging water vapor; the exhaust port 6 and the return air port 4 are connected through a recovery pipe 7.

[0016] In this embodiment, more specifically, the hot gas enters the ventilation chamber 13 from the air inlet 3, and after the hot gas fills the entire ventilation chamber 13, it surrounds the entire drying chamber 121, so that the drying chamber 121 is isolated from the outside world; the hot air with moisture in the drying chamber 121 will be discharged from the exhaust port 6, and then enter the recovery pipe 7. The gas passing through the recovery pipe 7 is processed and then re-enters the ventilation chamber 13 from the connected return air port 4 to be recycled, thereby effectively reducing heat loss and improving heat utilization.

[0017] In this embodiment, the guide roller set 2 is composed of a plurality of guide rollers 21 staggered up and down and evenly distributed in the drying chamber 121 .

[0018] In this embodiment, more specifically, the guide roller group 2 includes three guide rollers 21 arranged above the drying chamber 121, and two guide rollers 21 arranged below the drying chamber 121. The upper and lower guide rollers 21 are staggered and evenly distributed, and there is a certain distance between the upper and lower guide rollers 21. The wires are sequentially wound around multiple guide rollers 21, which increases the length and residence time of the wires in the drying chamber 121, which can increase the drying time and can more fully dry the moisture on the surface of the wires.

[0019] In this embodiment, there are multiple air outlets 5 ; the number of the air outlets 5 is equal to the number of the guide rollers 21 and the positions of the air outlets 5 correspond one-to-one to the guide rollers 21 .

[0020] In this embodiment, more specifically, the number of the air outlets 5 is 5 corresponding to the guide rollers 21, and the positions are arranged according to the guide rollers 21, namely, 3 air outlets 5 on the top and 2 air outlets 5 on the bottom, and the 5 air outlets 5 are respectively facing the corresponding guide rollers 21.

[0021] As a preference of this embodiment, a hair dryer 8 is provided on each of the air outlets 5 .

[0022] In this embodiment, more specifically, there are five hair dryers 8 arranged on the air outlet 5; they blow the hot gas in the ventilation chamber 13 toward the wires passing through the guide roller 21 through the rotation of their own fan blades, and can direct the heat to the wires passing through the guide roller 21 to accelerate the evaporation of surface moisture.

[0023] In this embodiment, an inlet hole 13 and an outlet hole 14 are respectively provided on both sides of the box body 1; the box body 1 is also provided with a wiper nozzle 131, a sponge adsorption box 132, and a conduit 133 on one side of the inlet hole 13; the sponge adsorption box 132 is arranged on the outer shell 11, the conduit 133 is arranged directly below the sponge adsorption box 132, and the wiper nozzle 131 is arranged at the front end of the sponge adsorption box 132; the box body 1 is also provided with a correction roller 141 for correcting the wires on one side of the outlet hole 14.

[0024] In actual application, the wires enter from the wiper nozzle 131. The wiper nozzle 131 is a conical shape that is narrow in front and wide in the back and is integrally formed of soft rubber. The wiper nozzle 131 can preliminarily scrape away the water on the surface of the wires; the sponge adsorption box 132 is filled with absorbent sponges. After the wires pass through the wiper nozzle 131, they enter the sponge adsorption box 132. The sponges in the box absorb the moisture on the outer surface of the wires when they come into contact with the wires. When the absorbed moisture reaches a certain level, it flows away through the conduit 133 arranged at the bottom of the sponge adsorption box 132; after the wires pass through the sponge adsorption box 132, they enter the box body 1 through the wire inlet hole 13 for drying.

[0025] In this embodiment, there are two straightening rollers 141 , and the gap between the two straightening rollers is adjustable, so as to straighten the electric wires passing through the guide roller 21 .

[0026] In this embodiment, the recovery pipe 7 is arranged on the top of the box body 1 and is connected to a drying device 9 and a filtering device 10 .

[0027] In this embodiment, more specifically, the hot air with moisture is collected through the recovery pipe 7; the drying device 9 and the filtering device 10 are respectively connected to the recovery pipe 7, and the hot air with moisture in the recovery pipe 7 is dried and filtered and then recycled through the return air port 4.

[0028] It should be noted that since the drying device 9 and the filtering device 10 are commonly used technical means, they are not explained in detail in this embodiment.

[0029] In this embodiment, there are two air inlets 3 , which are respectively arranged on one side of the wire inlet hole 13 and one side of the wire outlet hole 14 .

[0030] In this embodiment, more specifically, the air inlet 3 is arranged on both sides of the box body 1 and is a circular opening connected to the ventilation chamber 13 for connecting an external hot air blower so that the air inlet 3 can fill the entire ventilation chamber 13 more evenly and quickly.
