Abstract
The utility model relates to a nozzle with separated guiding atomizing plates which can be used for atomizing the liquid medium and particularly for atomizing water. The nozzle with separated guiding atomizing plates comprises a nozzle body, separated guiding atomizing plates, an impacting core, etc. Since the utility model adopts the separated guiding atomizing plates with various forms, the distribution of the water-spraying quantity can be changed according to the requirement; the atomization graininess and uniformity of the liquid can be improved; the consumption of the compressed air can be reduced. Thus the utility model has higher working adaptability and better economical benefit, and is mainly used for the steel industry to uniformly atomize and cool the continuous casting machine assembly and the hot rolling piece, and other places need spray cooling and dust removing.
Description
The utility model relates to a kind of nozzle that branch is led atomizing piece that has that is used for atomising liquid media, particularly water.It mainly is applicable in the steel and iron industry the spray place of evenly cooling and other need spray cooling and dedusting of continuous casting steel machine unit and hot rolling part.
At present both at home and abroad in the nozzle that uses, the face that falls into water is to rely on the spinning disk of the spout of nozzle and tangential opening or distribution that the spiral fuse is controlled injection flow rate and water particle atomizing situation for the nozzle of circle or annulus; The face of falling into water (then can only rely on nozzle configuration to control the distribution and the atomizing situation of injection flow rate as rectangle or oval-shaped flat nozzle for banded.Because this nozzle is limited to the adjustable range of injection flow rate and fogging degree thereof.Usually can produce defectives such as injection flow rate skewness, atomizing situation be bad, therefore, be difficult to adapt to the atomizing various workplaces that have certain requirements.The utility model then provides a kind of novel nozzle that branch is led atomizing piece that has at this problem, and it has solved problems such as injection flow rate skewness, atomizing situation be bad better.
The utility model is mainly led atomizing piece (2) and impact core (3) etc. and is formed by nozzle body (1), branch.The top of nozzle body is cylinder barrel shaped, and is shaped on internal thread; The bottom is cylinder barrel shaped or the hemispherical more smaller than upper diameter; Branch is led atomizing piece and is lacked shape for circular or circle, and it is positioned in the middle part of the nozzle body, and its plane is vertical with nozzle body axis; Divide the form lead atomizing piece to be divided into three kinds: the centre have the middle cavity type in hole, outer rim breach type that outer rim has breach and middlely have the hole, outer rim has the compound of breach.Dividing the shape of leading the atomizing piece interstitial hole can be circle, semicircle, waist shape, cydariform, the flat degree of lip-rounding and cross; The circle that is shaped as symmetrical distribution of its outer rim breach lacks.What constitute thus has a nozzle that branch is led atomizing piece, can change the distribution of injection flow rate as requested, has improved the atomized particle size and the uniformity of liquid simultaneously, has also reduced compressed-air actuated consumption.Have good operation adaptability and economic benefit.
Below with reference to accompanying drawing in detail embodiment of the present utility model is described in detail:

Figure 18, lead atomizing piece for outer rim breach type branch
Figure 19,20 leads atomizing piece for compound branch
Among the figure, the various branches that the utility model is showed are led the form of atomizing piece and the installation site in nozzle body thereof.All spray configuration and the atomizing situation to liquid produces directly influence.It is by throttling, damping action that middle cavity type branch is led atomizing piece, and the contact of strengthening solution-air mixes and prevents the directly ejection of bulky grain drop.After leading atomizing by branch, solution-airmixture reexpands, thereby mixes, and atomized particle size is little.It is with ejection medium (water or water and air) shunting guiding that outer rim breach type branch is led atomizing piece, in the conflict of atomizing piece place, mixing, sprays from spout more then.Therefore it has improved the uniformity and the atomizing effect that mix.Say effect in a sense with secondary-atomizing.It is except improving atomizing effect that compound branch is led the atomizing piece effect, has also increased to change the flexibility that injection flow rate distributes, divide generally speaking and lead the middle part that atomizing piece (2) is installed on nozzle body (1), that is the lower end of its top cylindrical tube.Because the nozzle operation environment temperature often changes big (0～800 ℃), atomizing piece lamellar body material and nozzle housing material are usually different, and both thermal coefficient of expansions are also different.Therefore take (H movingly between atomizing piece and the nozzle body in actual the use
7)/(h
6), promptly rely on metal plastic deformation to make lamellar body and nozzle body jam-packed.Practice shows that this method is very effective to the atomizing piece that plastic metal materials such as copper, aluminium, steel are made.For the following plastics atomizing lamellar body of work of normal temperature, still select for use movingly between itself and the nozzle body, promptly at side and the binding agent (as 502 glue, epoxy resin etc.) of coated on bottom side that lamellar body contacts with nozzle body, load onto and get final product to be insoluble to jetting fluid.
To the occasion of specific (special) requirements is arranged, can select movingly the mode of (or loose interference fits) and spot welding for use.
Divide the thickness of leading atomizing piece to be generally 0.5～1.0mm.
Claims (1)
1, a kind ofly have a nozzle that branch is led atomizing piece, it includes nozzle body, impact core etc.Of the present utility modelly be characterised in that it also includes branch and leads atomizing piece; The top of nozzle body is cylinder barrel shaped, and is shaped on internal thread.Its underpart is cylinder barrel shaped or the hemispherical more smaller than upper diameter; Branch is led atomizing piece and is positioned at the nozzle body middle part.Its plane is vertical with nozzle body axis.Divide and lead being shaped as circle or justifying scarce shape of atomizing piece.Its form has following three kinds: the centre have the middle cavity type in hole, outer rim breach type that outer rim has breach and middlely have the hole, outer rim has the compound of breach.Dividing the shape of leading the atomizing piece interstitial hole can be circle, semicircle, waist shape, cydariform, the flat degree of lip-rounding and cross; The circle that is shaped as symmetrical distribution of its outer rim breach lacks.
