The mixed gas ejector is technically characterized in that an independent negative pressure cavity is designed between the inner end of the inner ejection nozzle and the outer ejection nozzle, space of the negative pressure cavity can be adjusted through the external adjusting nut, a high-temperature gas channel communicated with the negative pressure cavity is formed in the outer ejection nozzle, due to the improved structure, the ejector can obtain adjustable ejection flow by adjusting the space of the negative pressure cavity, mixed gas can be ejected, the ejection temperature can be adjusted, the improved ejector can obtain the better heating temperature, and the production quality of the rotational molded products can be effectively improved.
Description
Technical field
The utility model relates to a kind of emitter construction being applied in rotational moulding production, specifically refers to mist injector.
Background technology
In rotational moulding production process, because Plastic Rolling Molds has the position that needs special heating in baking oven heating process, in order to address this problem, often need application sprayers to carry out back work, existing injector is to be made up of the inlet channel in outlet passageway and inner nozzle in outer nozzle, inner nozzle, outer nozzle etc. mostly, outlet passageway and inlet channel are connected, and heat for object thereby can spray high-temperature gas.But, in actual use, these injectors are limited to the structural design between inner nozzle and outer nozzle, injection flow is all fixing uncontrollable, therefore be also difficult to obtain good injection temperation, when being exclusively used in Plastic Rolling Molds and carrying out local heat, be all difficult to reach good temperature requirement, greatly affected the quality of rotational moulding product.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect of prior art and a kind of mist injector that can regulate injection flow and obtain better heating-up temperature is provided.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of mist injector, comprises that outer nozzle and sealing are arranged on the inner nozzle in outer nozzle; In described outer nozzle, be provided with outlet passageway, be provided with inlet channel in inner nozzle, this outlet passageway is connected with inlet channel, between described inner nozzle the inner and outer nozzle, is provided with negative pressure cavity, and inner nozzle outer end is provided with adjusting nut; Described outer nozzle is provided with and is communicated with respectively high temperature gas passage extraneous and negative pressure cavity.
Sealing installation structure between described inner nozzle and outer nozzle is to be provided with " O " RunddichtringO between inner nozzle middle part and outer nozzle.
In described outer nozzle, be provided with interior shoulder, between described inner nozzle inner face and interior shoulder, be provided with gap.
Described outlet passageway is inner small and outside big horn shape, ejection mist in this outlet passageway.
Described inlet channel is inner small and outside big taper hole shape, in this inlet channel, enters gases at high pressure.
Described high temperature gas passage is screwed hole passage.
Compared with prior art, the utility model is mainly between inner nozzle the inner and outer nozzle, to design one independently, and can carry out the adjustable negative pressure cavity of space size by outside adjusting nut, on outer nozzle, design again a high temperature gas passage that is communicated with negative pressure cavity, improve and make this injector can obtain adjustable injection flow by the space size that regulates negative pressure cavity by said structure, and then injection and the adjustable object of injection temperation of mist are realized, injector after improvement can obtain good heating-up temperature, also effectively improved the quality of production of rotational moulding product.
Brief description of the drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As shown in Figure 1,1. inner nozzle, 11. inlet channels, 2. outer nozzle, 21. outlet passageways, 22. interior shoulders, 23. high temperature gas passages, 3. adjusting nut, 4. " O " RunddichtringO, 5. negative pressure cavity.
Mist injector, as shown in Figure 1, it is a kind of auxiliary equipment of producing heating for Plastic Rolling Molds, is to be mainly made up of outer nozzle 2, inner nozzle 1 and adjusting nut 3 etc.
Described inner and outer nozzles is all tubular structures of hollow, and inner nozzle 1 is mounted in outer nozzle 2 by engage thread, then realizes sealing at inner nozzle 1 middle part by " O " RunddichtringO 4 being embedded and between outer nozzle 2 and install.
In described outer nozzle 2, be provided with that level connects and be inner small and outside big horn shape outlet passageway 21, in inner nozzle 1, be also provided with that a level connects and be inner small and outside big taper hole shape inlet channel 11, outlet passageway 21 is connected with inlet channel 11; Described outlet passageway 21 is for spraying the part of high-temperature gas mixture body with heating Plastic Rolling Molds; Described inlet channel 11 is connected with external pipe, and for delivery of gases at high pressure, this external pipe also can arrange a bringing-up section in baking oven simultaneously, so that the mist temperature that outer nozzle 2 sprays is higher, and the temperature needs of producing to reach rotational moulding.
Described inner unsettled being arranged in outer nozzle 2 of inner nozzle 1, is also provided with a negative pressure cavity 5 between this inner nozzle 1 the inner and outer nozzle 2, and this negative pressure cavity separates with the external world by " O " RunddichtringO 4, thereby forms independently chamber structure; Inner nozzle 1 outer end is provided with the adjusting nut 3 being threaded, screwing or unscrewing by adjusting nut, thereby the space size of having realized negative pressure cavity 5 regulates, and the space size of negative pressure cavity can directly have influence on the injection flow of injector, and then has realized the adjustable object of injection temperation.
Described outer nozzle 2 is provided with one and is communicated with respectively high temperature gas passage 23 extraneous and negative pressure cavity 5, and this high temperature gas passage is screwed hole passage, can be used for inputting high-temperature gas.Meanwhile, be also provided with interior shoulder 22, and between inner nozzle 1 inner face and interior shoulder 22, be provided with gap in outer nozzle 2, negative pressure cavity 5 can be formed and be communicated with outlet passageway 21 by gap.
Operation principle of the present utility model is: gases at high pressure enter the outlet passageway 21 of outer nozzle 2 through the inlet channel 11 of inner nozzle 1, known according to aerodynamics, in negative pressure cavity 5 between inner and outer nozzles, can form negative pressuren zone, thereby suck by the high temperature gas passage 23 on outer nozzle 2 high-temperature gas that baking oven produces, this high-temperature gas sprays together with after mixing in outlet passageway 21 with gases at high pressure, can act in the partial points of Plastic Rolling Molds, play the local heating of Plastic Rolling Molds, to produce qualified rotational moulding product.And can realize the size variation of negative pressure cavity 5 by the operation of adjusting nut 3, thus the mist injection flow of injector regulated, and reach rotational moulding and produce required temperature requirement.
