Description
Technical Field
The utility model relates to a fusion jetting balling process field, in particular to oxyhydrogen flame auxiliary fusion jetting balling device.
Background
In the field of ceramic melting, blowing and balling, because the temperature of the ceramic melt is up to more than 2000 ℃, a water-cooling carbon steel launder is usually adopted, and the launder can bear high temperature through the water-cooling effect and is practical for a long time. However, the practical use of the water-cooling launder faces a general problem, namely, the ceramic melt flows through the launder and crusts on the inner wall of the launder due to the water-cooling effect, the fluid becomes thick, the launder is usually designed to be a semi-open type, and is convenient for workers to clean the crusts in time, but the melt temperature is reduced by 200-.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an oxyhydrogen flame assists melting jetting balling-up device has solved the too fast shortcoming of gluing excessively of ceramic fuse-element cooling, the setting time is short.
On the one hand, the utility model provides a supplementary melting jetting balling-up device of oxyhydrogen flame, including furnace, chute, nozzle, oxyhydrogen flame spray gun, the chute rear end is connected with furnace's export, and the nozzle is connected with the chute front end, and the oxyhydrogen flame spray gun is installed at the chute front end, and the export of chute is aimed at to oxyhydrogen flame spray gun spun flame.
Furthermore, the nozzle is positioned below the front end of the launder, and the direction of the high-speed airflow sprayed by the nozzle forms a certain angle with the direction of the melt flowing out of the launder.
Furthermore, the oxyhydrogen flame spray gun is positioned below the front end of the flow groove, and the direction of the high-speed airflow sprayed by the nozzle forms a certain angle with the direction of the flame sprayed by the oxyhydrogen flame spray gun.
Furthermore, a bracket is arranged on the hearth, a fixing plate is arranged on the bracket, and the oxyhydrogen flame spray gun is arranged on the fixing plate.
Furthermore, 5-10 oxyhydrogen flame spray guns are installed side by side.
The utility model discloses a supplementary melting of oxyhydrogen flame jetting balling-up device compares prior art beneficial effect and lies in:
1. the melt flows out and then is converged with the high-speed airflow of the nozzle and the high-speed flame generated by the oxyhydrogen flame spray gun at the outlet of the flow channel, the high-speed flame enables the nozzle gas and the melt to be heated and heated rapidly, the melt is dispersed in different airflow directions, the temperature of the melt close to the melting point is rapidly increased by 500 ℃, the viscosity of the melt is lower, the melt is dispersed into thinner and more open droplets by the airflow, the solidification time after the melt is dispersed is further prolonged, and the sprayed melt has more time to retract into a spherical shape under the surface tension.
2. By utilizing the high-speed flame auxiliary combustion process, the negative influence of the water-cooling low temperature of the launder and the low temperature of the nozzle gas on the sphericity of the sprayed balls is reduced, and the convenience of cleaning the crusts of the water-cooling launder is ensured.
3. The high-speed flame generated by the oxyhydrogen flame spray gun only generates water vapor and cannot react with the ceramic melt to generate C-containing impurities.
Drawings
The accompanying drawings, which form a part hereof, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention without undue limitation. In the drawings:
FIG. 1 is a schematic structural view of an oxyhydrogen flame-assisted fusion blowing balling device according to the present invention;
fig. 2 is a side view of fig. 1.
Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in figure 1, the utility model provides an oxyhydrogen flame assists melting jetting balling device, including furnace 1, chute 2, nozzle 3, oxyhydrogen flame spray gun 5, the export of chute 2 rear end and furnace 1 is connected, and nozzle 3 is connected with chute 2 front end below. Install support 7 on furnace 1, install fixed plate 8 on support 7, oxyhydrogen flame spray gun 5 installs on fixed plate 8, and oxyhydrogen flame spray gun 5 includes 9, and 9 oxyhydrogen flame spray guns 5 arrange side by side, also can arrange side by side and install 5 ~ 10. The oxyhydrogen flame spray gun 5 is positioned below the front end of the flow groove 2, and the flame 6 sprayed by the oxyhydrogen flame spray gun 5 is aligned with the outlet of the flow groove 2. The direction of the high-speed gas flow sprayed by the nozzle 3 forms a certain angle with the direction of the melt 4 flowing out of the launder 2, the direction of the high-speed gas flow sprayed by the nozzle 3 forms a certain angle with the direction of the flame 6 sprayed by the oxyhydrogen flame spray gun 5, therefore, the melt 4 flowing out is converged with the high-speed gas flow of the nozzle 3 and the high-speed flame 6 generated by the oxyhydrogen flame spray gun 5 at the outlet of the launder 2, the high-speed flame 6 enables the gas of the nozzle 3 and the melt 4 to be rapidly heated and heated, the melt 4 is dispersed in different gas flow directions, the temperature of the melt 4 close to the melting point is rapidly increased by 300-.
An oxyhydrogen flame spray gun 5 is adopted, the temperature of the continuously sprayed high-speed flame 6 exceeds 2800 ℃ and is higher than the melting point of the melt 4, so that the melt 4 at an outlet can be preheated in time; the transonic flow of the high velocity flame 6 itself, in a direction different from that of the nozzle 3, serves to further assist in dispersing the melt 4. The high-speed flame 6 generated by the oxyhydrogen flame spray gun 5 only generates water vapor and does not react with the ceramic melt 4 to generate impurities containing C.
The techniques not described above are common general knowledge of the skilled person. Be less than or be greater than all including this number. The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
