Abstract

The utility model provides a cable blowing drier used in the electric wire and cable production line. A tapered tube is sheathed in air accumulation housing. The end surface between the tapered tube and the air accumulation housing is coated with a flange to form a gas collection chamber. A plurality row of inclined bores are arranged on the tapered tube. After attached to the air accumulation housing, the high pressure air source jets to the cable from the bore. The first row of inclined bores are used to blow off the water film and water drop on the cable. The second row of inclined bores are used to further dry the cable. Needing less air source pressure and flow quantity, the utility model can dry the cable.

Description

Cor blowing drier

The utility model relates to the cable drying equipment of using on a kind of electric wire production line.

On the cable production line, the cable production process is: cable by the bosh cooling, dries up after extruding on the extruder, head-stamp, and electric spark punctures check and the eccentric test of external diameter.In the prior art, drying up operation is that high pressure and mass flow air are delivered on the production line by ventilation duct, by powerful air-flow the moisture content on the cable is blown out Shui Mist, distributes in the space, reaches the purpose of cable drying.Its required high pressure draught pressure is 20 kilograms per centimeter ², flow is bigger.This just needs to set up pneumatics room comparatively huge, that need the personal management, and equipment investment is big, and power consumption is big.

The purpose of this utility model is to provide a kind of device that needs to adopt the source of the gas of less pressure and flow and can effectively make the cable drying, to reach the saving equipment investment, the effect of energy savings.

The utility model adopts following technical proposals to achieve the above object: the cable that comes out from bosh passes through a gas collection housing, fixes a joint on the gas collection housing, and high pressure draught is connected to this joint by flexible pipe and air-flow is imported in the gas collection housing.Be characterized in conical pipe of central axial direction arrangement that cable along the line passes through in the gas collection housing, end face forms collection chamber with the flange sealing between conical pipe and the gas collection housing, plurality of rows inclination aperture is arranged on the conical pipe, and the little centerline hole of every row intersects at a point on the axis of conical pipe.Its operation principle is: after high pressure draught enters collection chamber between gas collection housing and the conical pipe, spray on cable by aperture again, thereby form jet at a high speed, bigger kinetic energy is arranged, and owing to intersect at a point on the online cable axis of the little centerline hole of every row, little centerline hole becomes the Blunt angle with the cable axes intersect again, and this just makes the little gas flow hole of first float effectively blow moisture film or the water droplet that is attached on the cable off, and second aperture that arranges the beginning further dries up cable.

In order to make aperture sprays from the conical pipe air-flow can blow and dry up moisture content on the cable effectively off, the angle between the center line of aperture and the conical pipe axis can be 40 °～70 °.Aperture on the conical pipe can have 2～3 rows, and every row can have 2～8 apertures.The material of its gas collection housing, joint, conical pipe and flange can be metal or engineering material.

From above-described technical scheme, can obviously find out, adopt the utility model, only need to adopt the source of the gas of less pressure and flow just can effectively cable be dried up, save equipment investment and energy savings thereby reach.Test factually and show, if adopt than low capacity revolve air pump from heart formula Vortex, power of motor is 1.1 kilowatts, output pressure is 0.14 kilograms per centimeter ², gauge pressure and flow are 95 meters ³In/time, cable speed reaches 150 meters/minute, and cable is dried up.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further.

Accompanying drawing is the structural representation of an embodiment of the present utility model.

Referring to accompanying drawing, gas collection housing (2) is gone up a fixedly connected joint (1), the central axial direction that cable along the line passes through in gas collection housing (2) is settled a conical pipe (3), the big end of conical pipe (3) and flange (5) are made one, flange (5) is screwed on an end face of gas collection housing (2), the other end of gas collection housing (2) is being screwed a flange (6) that centre bore is arranged, the small end of the centre bore of flange (6) and conical pipe (3) is sealed and matched, so form collection chamber (4) between gas collection housing (2) and the conical pipe (3), two row's apertures (7) are arranged on the conical pipe (3), every row has 2 apertures, hole diameter is 2 millimeters, and angle [alpha] is 60 ° between the center line of aperture (7) and conical pipe (3) axis.Gas collection housing (2), joint (1), conical pipe (3) and flange (6) are all made with Rust steel not.

The utility model is through practical application, and the electric wire of production surface institute lettering body is complete clear, lovely luster. The utility model also has the advantages such as simple in structure, easy to operate, cheap, stable and safe in operation.
