Abstract

The utility model discloses a cutting nozzle with whirl flame, comprising a casing and a core, wherein, the core 10 is composed of a core tail 11, a core waist 12, and a core head 13; the centre shaft of the core 10 is penetrated with a spray orifice 14 for the high-pressure oxygen stream and an inner preheating flame tunnel 15, the core head 13 is provided with six air inlet ports 16, three gas spray holes 17 are uniformly distributed between the outer ring and the center shaft of the coil tail 11, and five spiral screw gas grooves 18 are uniformly distributed on the outer ring of the core tail 11. The utility model is suitable for the high-temperature fusion cutting of the concrete, and the dross of the concrete can be eliminated conveniently; the utility model has the advantages of high fusion cutting speed and good fusion cutting effect.

Description

Cutting nozzle with whirl flame

The utility model relates to a kind of concrete cutter carries out fusion cutting to concrete component swirl flame cutting torch that is used for.

Concrete cutting is a stubborn problem on the building industry.At present, artificial Drilling is used in the cutting of Non-metallic Building Materials perforation, and the speed of giving a farfetched interpretation is slow, and the position of giving a farfetched interpretation is inaccurate, and in the process of giving a farfetched interpretation, concrete component is subject to vibrations, shock effect.This method workload is great, the utensil heaviness, and workman's working environment is very abominable.

The purpose of this utility model provides a kind of being applicable to concrete is carried out the high temperature fusion cutting, and melting cut rate is fast, is convenient to get rid of the swirl flame cutting torch of concrete slag.

The purpose of this utility model is achieved in that the utility model comprises overcoat and fuse, fuse is by core tail 11, core waist 12, core print 13 3 parts are formed, space between core waist 12 and the overcoat 20 constitutes pressure stabilizing cavity, fuse 10 axis be installed with high pressure oxygen flow spray orifice 14 and in give hot flame duct 15, on core print 13, also be installed with six air admission holes 16, even three fumaroles 17 that distribute between core tail 11 outer rings and central shaft, the spiral air drain 18 of 5 curls that on core tail 11 outer rings, evenly distribute.

Advantage of the present utility model and effect are significant, use the utility model, mix concrete cutter and source of the gas, can carry out fusion cutting, molten hole, get rid of the concrete slag concrete-containing building material, guarantee the effect and the fusion cutting quality of fusion cutting, improve labour intensity and environment.

Fig. 2 is the overcoat cutaway view of an embodiment of the utility model.

Fig. 3 is the fuse cutaway view of an embodiment of the utility model.

Fig. 4 is the overcoat cutaway view of another embodiment of the utility model.

Fig. 5 is the fuse cutaway view of an embodiment in the utility model.

Drawing reference numeral explanation, fuse 10, core tail 11, core waist 12, core print 13, high pressure oxygen flow spray orifice 14, in give hot flame duct 15, air admission hole 16, fumarole 17, spiral air drain 18, overcoat 20.

Referring to accompanying drawing, the utility model is assembled by overcoat 20 and fuse 10.Outer casing inner wall is into stair-stepping chamber, and after assembling, the space between core waist 12 and the overcoat 20 constitutes pressure stabilizing cavity.Fuse 10 axis be installed with high pressure oxygen flow spray orifice 14 and in give hot flame duct 15, on core print 13, also be installed with six air admission holes 16, between core tail 11 outer rings and axis, evenly be installed with three fumaroles 16, between core tail 11 outer rings and axis, evenly be installed with three fumaroles 17, the spiral air drain 18 of 5 curls that on core tail outer ring, also evenly distribute.Fumarole 17 can be parallel with axis, as accompanying drawing 5, or and axis β in an acute angle, the β optimum valuing range is 0 °--30 °.As accompanying drawing 3, the angle α optimum valuing range of spiral air drain and axis is 10 ° to 45 °, and the trapezoidal chamber of overcoat 20 inwalls can be three ladders, as accompanying drawing 2, or four ladders, as accompanying drawing 4.

Claims

1, a kind of swirl flame cutting torch, form by fuse and overcoat, it is characterized in that comprising core tail 11, core waist 12, core print 13 3 parts, fuse 10 axis be installed with high pressure oxygen flow spray orifice 14 and in give hot flame duct 15, on core print 13, also be installed with six air admission holes 16, even three fumaroles 17 that distribute between core tail 11 outer rings and center, the spiral air drain 18 of 5 curls that on core tail 11 outer rings, also evenly distribute.

2,, it is characterized in that also having a pressure stabilizing cavity between described core waist 12 and the overcoat 20 by claim 1 a swirl flame cutting torch.

3, by the swirl flame cutting torch of claim 1, the angle α optimum valuing range that it is characterized in that described spiral air drain 18 and axis is 10 ° to 45 °.
