Description
Technical field
The utility model relates to industrial muzzles technical field, for the industry such as spraying dry, atomization of liquid reaction, medicine liquid spray, agricultural, medical aspect, is applicable to the occasion that pressure is low, flow is large, particularly a kind of centrifugal spraying nozzle.
Background technology
(1) liquid particles that hollow cone nozzle produces is the trickleest, and size distribution is very narrow, nozzle atomization excellent effect, and mass transfer effect is good.But the little mass flow of latus rectum is little, maximum spray angle is 90 °-130 °, so hollow cone bleed type is applicable to high-pressure low-flow.
(2) the hollow cone nozzle of solid cone nozzle and corresponding (pressure and flow) is compared, and the droplet particles of solid cone nozzle is larger.The feature of solid cone nozzle is large discharge scope, multiple jet angle, but needs higher pressure.
(3) spray shapes of fan nozzle has very clear, sharp profile.The liquid that nozzle configuration determines ejection is flat fan-shaped, and spray shapes can not be full of reactor inner chamber really.
(4) liquid of spiral nozzle ejection is in smooth column, and spray shapes the same as fan nozzle can not be full of reactor inner chamber.
The vortex atomizing nozzle of the nozzle related in the prior art mainly little atomizing angle of low-pressure low flow.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of centrifugal spraying nozzle, and structure is simple, and save material, nebulization efficiency is high, and nozzle exit pressure scope is at 0.2-0.5MPa, and flow 2-5m3/h, traditional industry bleed type is beyond one's reach.
Technical solution of the present utility model is as follows:
A kind of centrifugal spraying nozzle, its feature is, comprises nozzle body and centrifugal body, is provided with endoporus in this nozzle body, the end of this endoporus is taper, the end of nozzle body is provided with spout, and described centrifugal body is Step Shaft, is provided with centre bore in this centrifugal body, this centrifugal body is threaded in the endoporus of this nozzle body, and form eddy flow chamber between the outer rim of this centrifugal body and endoporus, described spout, endoporus are connected with centre bore, described centrifugal body be circumferentially evenly provided with multiple aperture.
The interior cone angle in described eddy flow chamber is 120 ° ~ 160 °.
Described multiple apertures are 3 ~ 6.
Compared with prior art, the beneficial effects of the utility model are:
1, structure is simple, and save material, nebulization efficiency is high, is applicable to low pressure and mass flow, and nozzle exit pressure scope is at 0.2-0.5MPa, and flow 2-5m3/h, traditional industry bleed type is beyond one's reach.
2, spray uniform particle sizes, injection axial velocity ratio is more smooth.
3, nozzle spray angle is very large, sprays inner chamber and there is not dead angle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model centrifugal spraying nozzle.
Fig. 2 is the structural representation of centrifugal body in the utility model.
Fig. 3 is A-A sectional view in Fig. 2.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail; the present embodiment is implemented under premised on technical solutions of the utility model; give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Fig. 1 is the structural representation of the utility model centrifugal spraying nozzle, as shown in Figure 1, 1, a kind of centrifugal spraying nozzle, comprise nozzle body 1 and centrifugal body 2, endoporus is provided with in this nozzle body, the end of this endoporus is taper, the end of nozzle body is provided with spout, described centrifugal body 2 is Step Shaft, centre bore is provided with in this centrifugal body 2, this centrifugal body 2 is threaded in the endoporus of this nozzle body, and form eddy flow chamber 3 between the outer rim of this centrifugal body 2 and endoporus, described spout, endoporus is connected with centre bore, described centrifugal body 2 be circumferentially evenly provided with multiple aperture 4.
The interior cone angle in described eddy flow chamber is 120 ° ~ 160 °.
Described multiple apertures 4 are 3 ~ 6.
The utility model centrifugal spraying nozzle, its material is stainless steel, and in the present embodiment, conveyor screw circumferentially has 6 apertures, as shown in Figure 2.
Described spout, internal taper hole are connected with inner via hole, have a plurality of fluids eddy flow to form high pressure tangential force in eddy flow inner chamber, and jet exit together with the middle axial liquid stream that one has a certain speed, forms large firing angle and coverage rate.Liquid passes through nozzle chamber through circular outer ends to tangential small-hole feed liquor, after centrifugal rotation, tangentially flows into spin chamber and produces high-speed rotational, form rotary-atomizing mist torch through spray orifice ejection.Jet exit diameter is comparatively large, and form high pressure in nozzle eddy flow chamber after, the injection liquid material of energy large discharge, ensures the requirement of spraying of material.Spray particle diameter little and even, angle of coverage greatly, ensures that liquid material is full of inner chamber.Compared with conventional spout, this New Low Voltage large discharge vortex atomizing nozzle, structure is simple, and required pressure is low, and flow is large, easy to assemble, can be mass.
