Description
Technical field
The present invention relates to a kind of ceramic particle and produce equipment, particularly relate to the structure design of a kind of superhigh temperature aerosolization nozzle.
Background technology
Existing High Temperature Gas atomizer is currently only used for metal material, and such as stainless steel shot-peening pearl, in the production of iron or Al alloy powder etc., relative temperature is relatively low, and typically at 1000 DEG C ~ 1700 DEG C, but the fusing point of ceramic material is higher, typically up to more than 2000 DEG C.Tradition aerosolization nozzle all uses metal material, such as stainless steel etc..But substantially this kind of material cannot meet 2000 DEG C of high temperature above radiation.
And tradition aerosolization nozzle is continuous production, often arranges chilled water unit on aerosolization nozzle, thus structure is relative complex, when aerosolization nozzle maintenance, replacing, difficulty is relatively big, and cost is difficult to reduce.
Summary of the invention
The defect existed in view of above-mentioned prior art, the purpose of the present invention is to propose to the special circumferential weld nozzle of a kind of superhigh temperature aerosolization ceramic material, solves the high temperature resistant problem that circumferential weld nozzle application produces in ceramic material.
The above-mentioned purpose of the present invention, to be achieved by the following technical programs: the special circumferential weld nozzle of a kind of superhigh temperature aerosolization ceramic material, it is secured to the resistance furnace furnace bottom just to discharging opening, it is characterized in that: described resistance furnace furnace bottom is integrated is provided with water-cooled portion, described special circumferential weld nozzle is to be assembled, by upper cover and lower cover, the adjustable nozzle of gap width of giving vent to anger constituted, wherein closing on the described upper cover of resistance furnace furnace bottom is the of a relatively high annular silicon member of heat radiation intensity, and upper cover is bolted to resistance furnace furnace bottom the water-cooled portion that fits by first, described lower cover is the stainless steel ring that heat radiation intensity is relatively low, and lower cover is fixed on by the second bolt and gasket seal and covers and form the nozzle of circumferential weld shape with upper cover.
Further, described annular silicon member is by the integrated ring of the compound of silicon, and the compound of described silicon is at least SiC or Si3N4。
Further, it is characterised in that: it is provided with sealing ring between the upper cover of described special circumferential weld nozzle and resistance furnace furnace bottom.
Further, described gasket seal has the degree that screws by the second bolt and adjusts the adjustable thickness of gas gap width.
Application this special circumferential weld nozzle of the present invention, compare to tradition aerosolization nozzle have the significant advantage that and use the material design of different high temperature resistant degree and manufacture split type nozzle, make the high temperature heat radiation that nozzle adapts to more than 2000 DEG C, water-cooled portion is moved to furnace bottom simultaneously, make nozzle arrangements more simplify, reduce weight, be prone to handling；Use resistant to elevated temperatures gasket seal, improve the adjustment property freely of circumferential weld width, gas output.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the present invention special circumferential weld nozzle.
Detailed description of the invention
Hereinafter accompanying drawing the most in conjunction with the embodiments, is described in further detail the detailed description of the invention of the present invention, so that technical solution of the present invention is more readily understood, grasps.
The present invention breaks through the limitation of conventional art, and innovation proposes the special circumferential weld nozzle of a kind of superhigh temperature aerosolization ceramic material, solves the high temperature resistant problem that circumferential weld nozzle application produces in ceramic material.
The present invention special circumferential weld nozzle one preferred embodiment is as it is shown in figure 1, this special circumferential weld nozzle 3 is secured to just resistance furnace furnace bottom 1 to discharging opening.From the point of view of fine-characterization structure, this resistance furnace furnace bottom 1 is integrated is provided with water-cooled portion 2；And water cooling part is designed bottom this resistance furnace, it is intended to simplify nozzle arrangements, alleviate nozzle weight, it is easy to be individually replaced nozzle arrangement.
As shown in the figure, this special circumferential weld nozzle 3 is to be assembled, by upper cover 31 and lower cover 32, the broad-adjustable nozzle in gap 33 of giving vent to anger constituted, wherein closing on the described upper cover 31 of resistance furnace furnace bottom is the of a relatively high annular silicon member of heat radiation intensity, mainly by the integrated ring of compound of silicon, and the compound of silicon can be SiC, it is also possible to be Si3N4.Upper cover 31 is fixed on resistance furnace furnace bottom 1 the water-cooled portion 2 that fits by the first bolt 42, and this upper cover is close to resistance furnace, therefore suffered caloradiance is bigger, use the compound of above-mentioned silicon, there is stronger heat resistance, and by it directly and joint, water-cooled portion, can effectively, quickly cool down.And due to lower cover 32 from resistance furnace relatively far away from, significantly reduce with caloradiance suffered by the temperature rate of change of product and trend, therefore can use the relatively low stainless steel ring of heat radiation intensity, and lower cover 32 is fixed on upper cover 31 by the second bolt 41 and gasket seal 34 and is formed the nozzle 33 of circumferential weld shape with upper cover 31.It addition, upper cover 31 and lower cover 32 attaching are formed with ring-like gas chamber, and air inlet 6 is just located therein, and in actual production process, the high pressure draught of air inlet is through ring-type gap ejection of giving vent to anger.
For improving air-tightness further, between the upper cover 31 of above-mentioned special circumferential weld nozzle and resistance furnace furnace bottom 1, it is provided with sealing ring 5.
As the optimization of such scheme, above-mentioned gasket seal 34 has the degree that screws by the second bolt and adjusts the adjustable thickness of gas gap width, is effectively improved the general applicability of this special circumferential weld nozzle.
As fully visible, application this special circumferential weld nozzle of the present invention, uses the material design of different high temperature resistant degree and manufactures split type nozzle, making the high temperature heat radiation that nozzle adapts to more than 2000 DEG C, water-cooled portion is moved to furnace bottom simultaneously, make nozzle arrangements more simplify, reduce weight, be prone to handling；Use resistant to elevated temperatures gasket seal, improve the adjustment property freely of circumferential weld width, gas output.
In addition to the implementation, the present invention can also have other embodiment.The technical scheme that all employing equivalents or equivalent transformation are formed, within all falling within scope of the present invention.
