Abstract
The utility model discloses a kind of impacting type atomizer, it comprises nozzle body, is located at the spout mold insert with nozzle and the knee of nozzle body spraying end face.The vertical end of this knee is fixed on the spraying end face of nozzle body, the other end of knee is the front portion that striking face end extends to described spout mold insert, and just to described nozzle, the end of the striking face end of knee is spherical shape, and the diameter of this spherical shape is greater than the diameter of described nozzle.This nozzle arrangements is reasonable, and process and assemble is simple, and production cost is cheap, and wide accommodation, atomizing effect is good.
Description
Technical field
The utility model relate to the nozzle of fluid atomizing, particularly relates to that a kind of structure is simple, at the bottom of manufacturing cost, the impacting type atomizer of long service life.
Background technology
Nozzle is parts crucial in a variety of spray, spraying, oil spout or abrasive blast equipment.Atomizer is that the atomization of liquid can spray by one, and a kind of device of even suspension in air.For impacting type atomizer, its operation principle is that a striking face is clashed in the high-speed jet spraying spray orifice, and form moisture film at striking face edge, moisture film is torn fragmentation after leaving striking face and is atomized.Impacting type atomizer has that structure is simple, and processing and manufacturing cost is low, and atomizing effect is stablized, relatively not easily the advantage such as blocking.The key factor affecting impacting type atomizer atomizing effect has: jet diameter, stroke speed, striking face geomery.The moisture film that jet diameter is less, stroke speed is faster, striking face spreads out is thinner, and the fogdrop diameter after atomization is less.In general, under certain jet diameter and stroke speed, in order to make moisture film that striking face spreads out as far as possible thin, the area that moisture film spreads out on striking face should be as far as possible little, and namely the size of striking face should be as far as possible little.
In order to reduce striking face size, existing impacting type atomizer all adopts nozzle needle needle point as the shock target of high-speed jet, due to jet diameter and nozzle needle needle point all very tiny, this just to jet with spray tip alignment accuracy very high requirement is proposed.General nozzle needle is the draw point being converted into hook solid be fixed on nozzle body, and this namely requires that the assembly precision of nozzle needle is very high, and also very high to the requirement of the dimensional stability of the material of crotch draw point.In order to reduce these required precisions, more existing shower nozzle adopts larger pin end striking face, and so make fogdrop diameter thicker, the form of spraying and spatial distribution become flat, and the uniformity of spraying certainly is also degrading.
Therefore, provide the impacting type atomizer that the dimensional stability requirements of a kind of assembly precision and material is not high, to reduce manufacturing cost, the service life of prolonging nozzle is industry problem demanding prompt solution.
Summary of the invention
The utility model is the technical problem solving existing impacting type atomizer, a kind of processing technology is proposed simple, to the assembly precision of nozzle and the not high impacting type atomizer of the dimensional stability requirements of material, thus reduce manufacturing cost, the service life of prolonging nozzle.
A kind of impacting type atomizer that the utility model proposes, it comprises nozzle body, is located at the spout mold insert with nozzle and the knee of nozzle body spraying end face.The vertical end of this knee is fixed on the spraying end face of nozzle body, the other end of knee is the front portion that striking face end extends to described spout mold insert, and just to described nozzle, the end of the striking face end of knee is spherical shape, and the diameter of this spherical shape is greater than the diameter of described nozzle.
Preferably, the spraying end face center of described nozzle body is provided with inlaid hole, and described spout mold insert is fixed in inlaid hole, and spraying end face is also provided with the installing hole that fixing described knee is vertically held, and the pipeline link of nozzle body is established admission chamber and communicates with inlaid hole.
The diameter of described nozzle is 0.1 ~ 0.3mm, and the diameter of described knee end spherical shape is 1 ~ 2mm.
The diameter of knee end of the present utility model spherical shape is greater than the diameter of nozzle, greatly reduces the requirement of the alignment precision of jet and knee.Although the size of end ball is comparatively large, the area of the moisture film spread out on striking face after impinging jet is still less, and the thickness of moisture film is also thinner, ensure that the spatial distribution form of the tiny of fogdrop diameter and spraying is uniform inverted conical shape.This nozzle arrangements is reasonable, and process and assemble is simple, and production cost is cheap, and wide accommodation, atomizing effect is good.
Accompanying drawing explanation
Below by being that embodiment and accompanying drawing are further described the utility model, wherein:
Fig. 1 position the utility model preferred embodiment cut-away illustration.
Detailed description of the invention
As shown in Figure 1, a kind of impacting type atomizer that the utility model preferred embodiment is shown, comprises nozzle body 1, is located at the spout mold insert 2 with nozzle 202 and the knee 3 of nozzle body spraying end face 102.
Spraying end face 102 center of nozzle body 1 is provided with inlaid hole 104, spout mold insert 2 is fixed in inlaid hole 104, the pipeline link of nozzle body 1 is established admission chamber 108 and is communicated with inlaid hole 104, and the cylindrical of pipeline link is provided with the screw thread 110 be connected with liquid-transport pipe-line.Spraying end face 102 is also provided with an installing hole 106, knee 3 is the steel poles being converted into crotch-shaped, it is vertically held and is fixed in this installing hole 106, and the other end of knee is striking face end 302 extends to the front portion of described spout mold insert 2, and just to its nozzle 202, the end of the striking face end 302 of knee is no longer prong shape, but spherical shape 304, the diameter of this spherical shape is greater than the diameter of nozzle 202.In the present embodiment, spout mold insert 2 is made by high-abrasive material, and the diameter of nozzle 202 is 0.1 ~ 0.3mm, and the diameter of the spherical shape of knee 3 end is 1 ~ 2mm.As required, the diameter of nozzle 202 and the diameter of spherical shape also can choose different numerical value, as long as the diameter of restriction spherical shape is greater than the diameter of nozzle 202.
Because the diameter of the spherical shape 304 of knee end is greater than the diameter of nozzle 202, greatly reduces the requirement of the alignment precision of jet and knee 3.Although the size of spherical shape 304 is comparatively large, the area of the moisture film spread out on striking face after impinging jet is still less, and the thickness of moisture film is also thinner, ensure that the spatial distribution form of the tiny of fogdrop diameter and spraying is uniform inverted conical shape.This nozzle arrangements is reasonable, and process and assemble is simple, and production cost is cheap, and wide accommodation, atomizing effect is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
