Large flame gun device

Abstract

The invention provides a large flame gun device, which comprises a water cooling sleeve and at least two small flame guns arranged in the water cooling sleeve, the small flame guns are circumferentially distributed, and the large flame gun device is characterized in that an observation pipe for observing the flame of the small flame guns is arranged in the center of the circumference surrounded bythe small flame guns. According to the scheme, the small flame gun is integrally assembled; the material processing efficiency is effectively improved; batch production of materials is facilitated; the retention time of the material in a high-temperature area can be effectively prolonged; the sufficient processing of the materials is convenient to improve; meanwhile, the size of flames, whether the flames are extinguished or not and the treatment condition of the materials can be observed in real time, the small flame guns are integrated, the local temperature of the flame guns can be increased conveniently, the machining effect and efficiency of the materials are further improved, meanwhile, maintenance of the single small flame gun is facilitated, and long-time production pause in the machining process is avoided.

Description

technical field [0001] The invention relates to burner technology, in particular to a large flame gun device. Background technique [0002] With the development and progress of science and technology, the demand for materials in various fields is gradually increasing. The application fields of nanomaterial metal powder are becoming more and more extensive, and the production requirements are getting higher and higher, and the demand is also increasing. It is more widely used in 3D printing. During the production process, the temperature of the molten metal after plasma atomization is several thousand degrees, but the atomization efficiency and effect are not very ideal. [0003] Patent No. CN206632370U discloses a tower-type metal atomization plasma generating device, including a draft tube, a draft tube assembly, at least 3 groups of plasma gun assemblies and a spray plate bracket; On the nozzle bracket, the plasma ejected from it converges at the center of the lower end o...

AI Technical Summary

Problems solved by technology

However, the device has the following disadvantages during use: 1. The overall combustion efficiency of the small flame gun is low, which cannot meet the needs of processing materials in large quantities; The residence time of the material in the flame is relatively short; 3. During the process of discharging the material, the small flame gun cannot observe the size of the flame in time, whether it is extinguished or not and the material treatment effect cannot be observed in time; 4. The cooling effect of the small flame gun alone is not good
