Description
Technical field
The utility model relates to a kind of ceramic particle production equipment, particularly relates to a kind of structural design of superhigh temperature aerosolization nozzle.
Background technology
Existing High Temperature Gas atomizer is at present only for metal material, and as stainless steel shot-peening pearl, in the production of iron or Al alloy powder etc., relative temperature is lower, and generally at 1000 DEG C ~ 1700 DEG C, but the fusing point of ceramic material is higher, generally reaches more than 2000 DEG C.Tradition aerosolization nozzle all adopts metal material, as stainless steel etc.But obviously this kind of material cannot meet more than 2000 DEG C hyperthermia radiations.
And traditional aerosolization nozzle is continuous production, often arranges chilled water unit on aerosolization nozzle, thus structure relative complex, when aerosolization nozzle maintenance, replacing, difficulty is comparatively large, and cost is difficult to reduce.
Utility model content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the special circumferential weld nozzle proposing a kind of superhigh temperature aerosolization ceramic material, solves the high temperature resistant problem that circumferential weld nozzle application is produced in ceramic material.
Above-mentioned purpose of the present utility model, to be achieved by the following technical programs: a kind of special circumferential weld nozzle of superhigh temperature aerosolization ceramic material, be secured to just to the resistance furnace furnace bottom of 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 assemble the adjustable nozzle of the gap width of giving vent to anger that forms by upper cover and lower cover, the described upper cover wherein closing on resistance furnace furnace bottom is the annular silicon member that heat radiation intensity is relatively high, and upper cover is bolted to resistance furnace furnace bottom by first and the water-cooled portion that fits, described lower cover is the relatively low stainless steel ring of heat radiation intensity, 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 that the compound of described silicon is at least SiC or Si by the compound of silicon integrated ring

4.
Further, it is characterized in that: between the upper cover of described special circumferential weld nozzle and resistance furnace furnace bottom, be provided with sealing ring.
Further, described gasket seal has the adjustable thickness being adjusted gas gap width by the degree that screws of the second bolt.
This special circumferential weld nozzle of application the utility model, compare to traditional aerosolization nozzle and there is significant advantage: adopt the material design of different high temperature resistant degree and manufacture split type nozzle, make nozzle can adapt to the high temperature heat radiation of more than 2000 DEG C, water-cooled portion moved to furnace bottom simultaneously, nozzle arrangements is more simplified, reduce weight, be easy to handling; Adopt 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 special circumferential weld nozzle of the utility model.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
The utility model breaks through the limitation of conventional art, and innovation proposes a kind of special circumferential weld nozzle of superhigh temperature aerosolization ceramic material, solves the high temperature resistant problem that circumferential weld nozzle application is produced in ceramic material.
As shown in Figure 1, this special circumferential weld nozzle 3 is secured to just to the resistance furnace furnace bottom 1 of discharging opening the preferred embodiment of the utility model special circumferential weld nozzle one.Fine-characterization structure, this resistance furnace furnace bottom 1 is integrated is provided with water-cooled portion 2; And by water cooling partial design bottom this resistance furnace, be intended to simplify nozzle arrangements, alleviate nozzle weight, be easy to change nozzle arrangement separately.
As shown in the figure, this special circumferential weld nozzle 3 is assemble by upper cover 31 and lower cover 32 the broad-adjustable nozzle in gap 33 of giving vent to anger formed, the described upper cover 31 wherein closing on resistance furnace furnace bottom is the annular silicon member that heat radiation intensity is relatively high, mainly by the integrated ring of the compound of silicon, and the compound of silicon can be SiC, also can be Si
3n
4.Upper cover 31 is fixed on resistance furnace furnace bottom 1 and 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 larger, adopt the compound of above-mentioned silicon, there is stronger heat resistance, and by it directly and joint, water-cooled portion, can effectively, fast cool.And due to lower cover 32 from resistance furnace relatively away from, significantly reduce with caloradiance suffered by the temperature rate of change of product and trend, therefore the stainless steel ring that heat radiation intensity can be adopted relatively low, and lower cover 32 to be fixed on upper cover 31 by the second bolt 41 and gasket seal 34 and to form the nozzle 33 of circumferential weld shape with upper cover 31.In 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 sprays through the gap of giving vent to anger of ring-type.
For improving air-tightness further, between the upper cover 31 of above-mentioned special circumferential weld nozzle and resistance furnace furnace bottom 1, be provided with sealing ring 5.
As the optimization of such scheme, above-mentioned gasket seal 34 has the adjustable thickness being adjusted gas gap width by the degree that screws of the second bolt, effectively improves the general applicability of this special circumferential weld nozzle.
As fully visible, this special circumferential weld nozzle of application the utility model, adopts the material design of different high temperature resistant degree and manufactures split type nozzle, making nozzle can adapt to the high temperature heat radiation of more than 2000 DEG C, water-cooled portion moved to furnace bottom simultaneously, nozzle arrangements is more simplified, reduce weight, be easy to handling; Adopt resistant to elevated temperatures gasket seal, improve the adjustment property freely of circumferential weld width, gas output.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
