Description
TECHNICAL FIELD
[0001] The utility model relates to cable production technical field especially a cable sheath cooling water air duct device. BACKGROUND
[0002] The sheath of cable is very high in temperature after extruding from the head of extruder, needs to cool down after passing through a section of cooling water tank to be able to be shaped. The cable is out of the cooling water tank, and the sheath surface will have cooling water residue, needs to remove it to prevent affecting the subsequent process, also avoids the erosion of cooling water to the internal conductor. The main practice in the industry is usually to place some sponges, towels and other water-absorbing materials at the outlet end of the cooling water tank to wipe off part of the cooling water on the surface of the sheath, and then use the air duct to blow air on the surface of the cable to remove the cooling water. Such a method has some defects, one of which is that the water-absorbing materials need to be replaced frequently, and the other is that the air duct generally blows cold air, which completely relies on airflow to blow water and still has the problem of not being able to blow dry. SUMMARY
[0003] The utility model aims at overcoming the insufficient in the background art, and provides a cable sheath cooling water air duct device which can better blow off the moisture on the surface of the cable sheath.
[0004] The technical scheme adopted by the utility model is as follows:
[0005] A cable sheath cooling water air duct device, comprising an air duct, an annular groove recessed inward from one end face by a certain depth is formed in the wall of the air duct, an end cap for closing the opening end of the annular groove is arranged on the end face, a through hole corresponding to the inner hole of the air duct is formed in the center of the end cap, the annular groove and the inner hole of the air duct are communicated through a circle of uniformly arranged inclined holes, and the inclined holes are arranged towards the entrance end of the inner hole of the air duct; an air inlet pipe communicated with the annular groove is fixed on the wall of the air duct, the air inlet pipe is connected with the outer pipeline of a heat exchanger through a fan, and the inner pipeline of the heat exchanger is connected with the cooling water return pipeline of a sheath extruder.
[0006] In a further scheme, the end cap is threadedly connected with the outer wall of the air duct.
[0007] In a further scheme, a sealing ring is arranged between the end cap and the end face of the air duct.
[0008] The utility model has the beneficial effects that the utility model changes the air outlet of the air duct into the inclined hole air outlet, blows water against the direction of the cable, and the blowing effect is better than that of the vertical blowing or the non-directional blowing, the utility model uses the high-temperature cooling water returned by the sheath extruder to exchange heat with the air inlet of the air duct, does not increase the power consumption, increases the temperature of the air outlet of the air duct, blows hot air to increase the temperature of the surface of the cable sheath, speeds up the evaporation of the residual water, and the longer the length of the air duct is, the better the effect is. BRIEF DESCRIPTION OF DRAWINGS

[0011] In order for those skilled in the art to more clearly understand the purpose, technical scheme and advantages of the present application, the present application will be further described below in conjunction with the drawings and examples, but the present application is not limited to the following examples.
[0012] In the description of the present application, it should be pointed out that the directions or position relationships indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like are based on the directions or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application in that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation.
[0013] As shown in Figure 1 The present embodiment provides a cable sheath cooling water wind cylinder device, which comprises a wind cylinder 1, an annular groove 2 is recessed inwardly from one end face of the cylinder wall of the wind cylinder 1 by a certain depth, an end cover 4 is arranged on the end face for closing the opening end of the annular groove 2, a through hole corresponding to the inner hole of the wind cylinder 1 is arranged at the center of the end cover 4, the end cover 4 is threadedly connected with the outer wall of the wind cylinder 1, and a sealing ring 3 is arranged between the end cover 4 and the end face of the wind cylinder 1 to prevent air leakage therefrom.
[0014] The inner hole of the wind cylinder 1 and the annular groove 2 are communicated through a circle of uniformly arranged inclined holes 5, and the inclined holes 5 are arranged towards the inlet end of the inner hole of the wind cylinder 1. When the inclined holes 5 are processed, the inclined holes 5 can be punched inwardly from the inlet end of the inner hole of the wind cylinder 1. If the length of the wind cylinder 1 is relatively long, the inclined holes 5 cannot be punched, and the inclined holes 5 can be punched inwardly from the outer wall of the wind cylinder 1. After the inclined holes 5 are punched, the process holes between the outer wall of the wind cylinder 1 and the annular groove 2 can be closed.
[0015] An air inlet pipe 7 communicating with the annular groove 2 is fixed on the cylinder wall of the wind cylinder 1, the air inlet pipe 7 is connected with the outer pipeline of a heat exchanger 10 through a fan 9, the other end of the outer pipeline is connected with the atmosphere through an air inlet pipe 12, and the inner pipeline of the heat exchanger 10 is connected with a cooling water return pipeline 11 of a sheath extruder.
[0016] On one hand, the water blowing effect of the inclined hole 5 is better than the vertical blowing or the non-directional blowing effect, and on the other hand, in order to ensure that the plastic required for the extrusion sheath can always be melted in the temperature range required by the processing technology, a cooling system must be arranged on the extruder, generally in the form of water cooling, the outlet (backflow hole) of the cooling water has a relatively high water temperature, and the heat of this part is usually wasted, the utility model utilizes the heat exchanger 10 to exchange the heat of the cooling water with the air inlet of the air duct 1, improves the temperature, and then sends the air to the annular groove 2 by the fan 9, and then blows out at a high speed from the inclined hole 5, so that the hot air blown on the sheath can accelerate the evaporation of the residual moisture, and the effect is further improved.
