Abstract

The utility model discloses a water-mist spraying device which comprises an atomization cover. The atomization cover is installed outside the low end of a cutting torch in a sleeved mode, a heat-resisting sleeve is additionally installed between the atomization cover and the outer side of the cutting torch, a plurality of small holes are formed in the periphery of the inner side of the heat-resisting sleeve, a water inlet pipe is connected with the side portion of the atomization cover, the water inlet pipe is a 90-degree right angle pipe, a water inlet end of one end of the water inlet pipe faces upward, and the other end of the water inlet pipe transversely penetrates through the atomization cover and is connected to the outer side of the heat-resisting sleeve. Preferably, each small hole is of circular shape and formed in the inner side of the heat-resisting sleeve in a circle. Due to the fact that liquid water which enters the atomization cover through the water inlet pipe is vaporized in a state of high temperature of the cutting torch and changed into water mist to be sprayed out, temperature of the local surface of cutter pipe fittings is reduced, thermal deformation can be effectively reduced, and the phenomena that surface slug returns in the process of cutting and slag adheres on opposite surfaces can be avoided. The water-mist spraying device is used for cutting system, can effectively solve the problem that the pipe fittings deform due to excess temperature when being cut, enables the pipe fittings to be cooled rapidly, prevents the slag from returning, and reduces the amount of slag discharging.

Description

A kind of water smoke spray equipment

Technical field

The utility model relates to spray system, particularly a kind of water smoke spray equipment for plasma cutting system.

Background technology

The cutting of existing plasma belongs to thermal cutting, and the cutting torch temperature is quite high during cutting pipes, because localized hyperthermia can cause the pipe fitting local deformation, influence cut quality, and when cutting, return slag and opposite face dross phenomenon appear in pipe fitting surface easily.

The utility model content

The utility model proposes a kind of water smoke spray equipment, when efficiently solving cutting pipes in the prior art because the too high problem that causes the pipe fitting distortion of temperature makes the pipe fitting cooling fast, anti-return slag, the dross amount reduces.

The technical solution of the utility model is achieved in that

A kind of water smoke spray equipment comprises the atomized cover that is sleeved on the outside, cutting torch lower end, installs heatproof sleeve additional between described atomized cover and the cutting torch outside, and described heatproof sleeve inner peripheral arranges a plurality of apertures, and described atomized cover sidepiece connects water inlet pipe.

Described water inlet pipe is 90 degree ells, and the one end is that water inlet end is directed upwardly, and the other end is horizontally through atomized cover and is connected to the described heatproof sleeve outside.

Described aperture is toroidal, is a circle and is arranged in described heatproof sleeve inboard, and vaporization becomes water smoke and is ejected to by described a plurality of apertures and wants the cutting pipes surface under the hot conditions of cutting torch end when the water spirt comes, and reduces its temperature.

Action principle of the present utility model is,

The liquid water that enters atomized cover by water inlet pipe is vaporized under the cutting torch condition of high temperature, becomes the water smoke ejection, and cutting pipes local surfaces temperature is reduced, and can effectively reduce thermal deformation, and can solve surface return slag and opposite face dross phenomenon when cutting.

The beneficial effects of the utility model are, are spray equipment with respect to the cooling provision of diced system increase before, are used for diced system, make the pipe fitting cooling fast, anti-return slag, the minimizing of dross amount.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of a kind of water smoke spray equipment of the utility model.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

With reference to Fig. 1, a kind of water smoke spray equipment comprises the atomized cover 2 that is sleeved on the outside, cutting torch 1 lower end, installs heatproof sleeve 4 additional between described atomized cover 2 and cutting torch 1 outside, and heatproof sleeve 4 inner peripheral arrange a plurality of apertures 41, and atomized cover 2 sidepieces connect water inlet pipe 3.

Water inlet pipe 3 is 90 degree ells, and one end 31 is for water inlet end is directed upwardly, and the other end is horizontally through atomized cover 2 and is connected to heatproof sleeve 4 outsides.

Above-mentioned aperture 41 is toroidal, is a circle and is arranged in heatproof sleeve 4 inboards, and vaporization becomes water smoke and is ejected to by described a plurality of apertures 41 and wants the cutting pipes surface under cutting torch 1 end hot conditions when water sprays, and reduces its temperature.

The direction of arrow is the water inlet direction among the figure.

Action principle of the present utility model is,

Water flows into water inlet pipe 3 from the direction of arrow shown in the figure, enter again in the atomized cover 2, liquid water is vaporized under the cutting torch condition of high temperature, become the heatproof sleeve 4 inboard a plurality of apertures that on every side arrange 41 ejections of water smoke from being sleeved on cutting torch 1 end, cutting pipes local surfaces temperature is reduced, thermal deformation can be effectively reduced, and surface return slag and opposite face dross phenomenon when cutting can be solved.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
