SUMMERY OF THE UTILITY MODEL

The utility model aims to: the utility model provides an electric wire drying device to solve among the prior art and lead to the ageing problem of cable insulation skin easily when spouting a yard department and drying to the cable.

The technical scheme adopted by the utility model is as follows:

the utility model provides an electric wire drying device, includes the base, the fixed stoving passageway that is equipped with on the base, the stoving passageway is the cylinder, stoving passageway is by outer shell, insulating layer, reflection stratum, heating device of being equipped with in proper order to interior, heating device is the magnetron, the reflection stratum be used for with the microwave that heating device sent assembles on the axis of stoving passageway.

Preferably, the heating devices are distributed along the axis of the drying channel in a central symmetry manner, and the number of the heating devices is not less than 8.

Preferably, the heat insulation layer is light refractory brick.

Preferably, the reflective layer is made of a galvanized sheet.

Preferably, microwave shielding covers are arranged at two ends of the drying channel, metal nets are arranged in the microwave shielding covers, and round holes are formed in the middle parts of the microwave shielding covers and the metal nets.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

(1) the utility model adopts the magnetron as a heating device, utilizes the microwave emitted by the magnetron for heating, and can ensure that the energy of the microwave is concentrated on the ink at the code spraying position to quickly dry the ink as the water molecules are easy to absorb the microwave and quickly heat up, and the materials such as rubber, plastic, metal and the like used by the cable per se have weaker absorption capacity on the microwave;

(2) the heating devices are distributed along the axis of the drying channel in a central symmetry manner, and can carry out drying treatment on the surface of the electric wire in an all-around manner; the situation that the code spraying cannot be directly irradiated by the heating device due to the fact that the heating device is shielded by the electric wire is avoided;

(3) by arranging the reflecting layer, the galvanized sheet is used for reflecting the microwave emitted by the magnetron, so that the microwave is concentrated on the axis of the drying channel, and the electric wire is exactly positioned on the axis when being dried, the utilization rate of microwave energy can be obviously improved, and the drying speed is accelerated;

(4) and microwave shielding covers are arranged at two ends of the drying channel, so that energy waste caused by the escape of microwaves from the inlet and the outlet of the drying channel can be reduced.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention.

Example 1

As shown in fig. 1 to 3, an electric wire drying device includes a base 1, a drying channel 2 is fixedly disposed on the base 1 for drying an electric wire, the drying channel 2 is cylindrical, the drying channel 2 is sequentially provided with a housing 3, a heat insulating layer 4, a reflective layer 5 and a heating device 6 from outside to inside, wherein the housing 3, the heat insulating layer 4 and the reflective layer 5 are all cylindrical, the heating device 6 is a magnetron capable of emitting microwaves to heat the electric wire, the reflective layer 5 is made of a galvanized plate and has a strong reflection capability to the microwaves, the microwaves emitted by the heating device 6 can be converged on an axis of the drying channel 2 to enhance a heating effect, the heating device 6 is centrally and symmetrically distributed along the axis of the drying channel 2, the number of the heating device 6 is 8, the surface of the electric wire can be dried in all directions, the heat insulating layer 4 is a light refractory brick, specifically, the heat insulation layer 4 is made of alumina air ball bricks, and has good heat insulation capability.

The working principle is as follows:

as shown in fig. 3, when the wire after code spraying is dried, the drying device is installed at the downstream of the code spraying device, and the wire passes through the round hole on the microwave shielding case 7, so that the wire is just positioned on the axis of the drying channel 2, the periphery of the wire is irradiated by the heating device 6, the absorption capacity of different substances to the microwave is different, the ink containing moisture is rapidly heated and evaporated to dryness, meanwhile, the heating speed of the wire insulation skin which is not easy to absorb the microwave is slow, and the lower temperature can be kept, thereby realizing that the drying speed is obviously improved on one hand, and reducing the aging of the wire insulation skin in the drying process on the other hand.
