Abstract

Disclosed is a combined atomizing nozzle, which belongs to the technology field of dust removal device. The utility model comprises a shell, which is characterized in that an inner core is cooperatively arranged on the inner cavity of the shell; an inlet hole at the lower part of the shell is communicated with an inner core cavity, the upper end of the inner core is cooperatively connected with a shell end by an end cap, and the central segment is connected with a shunting plate, a nozzle valve lever end on the shunting plate has a conical surface clearance fit with the inner core end, an airway formed between the outer wall of the inner core and the inner wall of the shell is communicated with the inlet hole and the ejection hole arranged on the upper end of the inner core. The combined atomizing nozzle has a novel conception, reasonable structure design, convenient maintenance and excellent application effect; adopting an internal-mixing structure and atomizing water by the mixing of air and water make a even spraying, and the spray capacity, the fog droplet and the spraying area are all tunable, thus the utility model can adapt to different situations of use; and a mist layer is formed and covered on easy- scattered dust, thereby preventing the dust from flying and spreading, meanwhile the production and maintenance cost are also reduced.

Description

The combined type atomizer

Technical field

The utility model belongs to the device for reducing dust technical field, is specifically related to a kind of combined type atomizer.

Background technology

Sprinkling formed water smoke and carries out depositing dust after the general employing of existing water spray depositing dust product was directly pressurizeed to water, drawbacks such as this series products ubiquity hydraulic pressure height, water consumption is big, water fog particle is thick, result of use is undesirable, the water resource waste problem is outstanding in the use, in depositing dust, depositing dust process, excess surface water occurs easily and cause that water pollutes, and to the requirement of withstand voltage height of equipment, manufacturing, maintenance difficulties strengthen, and have increased the weight of manufacturing cost and use cost.

The utility model content

The utility model aims to provide a kind of technical scheme of combined type atomizer of gas-vapor mix spraying, to overcome problems of the prior art.

Described combined type atomizer, comprise housing, it is characterized in that the housing inner chamber is equipped with inner core, the inlet opening that is arranged on lower housing portion is communicated with the inner core cavity, the inner core upper end is connected by end cap and shell end, the middle part connects flow distribution plate is set, and connects the nozzle valve rod termination that is provided with on the flow distribution plate and becomes conical surface matched in clearance with the inner core port, and the air flue that forms between interior outer core and the inner walls is communicated with the fumarole of air admission hole and the setting of inner core upper end.

Described combined type atomizer is characterized in that end cap and shell end threaded, and the inner core upper end is spirally connected and is provided with and cap, end cap and and cap press fit.

Described combined type atomizer is characterized in that inner core is the split fit structure, its upper and lower two parts respectively with the flow distribution plate threaded.

Described combined type atomizer is characterized in that being equipped with on the flow distribution plate limbers, the setting that is spirally connected of nozzle valve rod and flow distribution plate.

Described combined type atomizer is characterized in that connecting on the nozzle valve rod being provided with and locatees protruding footpath

Described combined type atomizer is characterized in that inner core is a pyramidal structure up and down.

Above-mentioned combined type atomizer is novel, reasonable in design, easy to maintenance, result of use good, adopt the internal-mixing structure, utilize air and mixing of water that water is effectively atomized, go out mist evenly and spray amount, water fog particle, sprinkling zone etc. adjustable, to adapt to different use occasions, and can cover on the dust that easily looses and form fumulus, dust is no longer scattered, also reduced manufacturing, maintenance cost simultaneously.

The specific embodiment

Below in conjunction with Figure of description the utility model is further specified:

As shown be the combined type atomizer, housing 2 inner chambers are equipped with the inner core 3 of pyramidal structure up and down, and the inlet opening 1 that is arranged on housing 2 bottoms is communicated with inner core 3 cavitys.Inner core 3 upper ends are connected by end cap 7 and housing 2 ends, end cap 7 and housing 2 end threaded, inner core 3 upper ends are spirally connected and are provided with and cap 9, end cap 7 with and cap 9 press fit, be equipped with sealing ring 8 between end cap 7 and housing 2 upper surfaces.The air flue 11 that forms between inner core 3 outer walls and housing 2 inwalls, air flue 11 middle parts are relatively thin, long, the fumarole 10 that air flue 11 and air admission hole 13 and inner core 3 upper ends are provided with is communicated with, and fumarole 10 can be set to two groups or more so that water, gas can fully mix the enhancing atomizing.Inner core 3 is the split fit structure, flow distribution plate 4 threaded that its upper and lower two parts are provided with by the middle part respectively.Be equipped with limbers 12 on the flow distribution plate 4, flow distribution plate 4 and nozzle valve rod 5 threaded, the water channel gap is less between nozzle valve rod 5 upper end outer walls and inner core 3 inwalls, nozzle valve rod 5 terminations become conical surface matched in clearance with inner core 3 ports, from the annular space ejection, can regulate spray angle behind the end face of mixing aqueous vapor impulse nozzle valve rod 5 by rotary nozzle valve rod 5.Connect on the nozzle valve rod 5 to be provided with and locate protruding footpath 6, inner core 3 can effectively be located, can not be offset, keep the spout angle stable.

During use, the compressed air of certain pressure enters from air admission hole 13, enter the gas-vapor mix district through air flue 11 from fumarole 10, the water of certain pressure 1 enters from the inlet opening, limbers 12 on flow distribution plate 4, inner core 3 cavitys enter the gas-vapor mix district, from the annular space ejection, can adjust spray amount, water fog particle, sprinkling zone etc. by regulating air pressure, hydraulic pressure or spray angle, behind the end face of mixing aqueous vapor impulse nozzle valve rod 5 to adapt to different use occasions.

Technical scheme disclosed in the utility model also can be applicable to devices such as humidification, cooling, or is applied to the spray woods device of anti-fire extinguishing system.
