[0002] Hollow spheroidization sintering furnaces are widely used in fields such as metallurgy, ceramics, and powder metallurgy. The core is to form a uniform hollow spheroidized structure of materials through high-temperature sintering. As the core part of the sintering furnace, the combustion system directly affects the heating uniformity of the materials, the sintering efficiency, and the quality of the final product. In the field of hollow spheroidization sintering furnaces, the combustion system is the key equipment for realizing the spheroidization and sintering of powder materials.

The output end of the motor four 7056 drives a blanking sphere 7057 to rotate and open, so that the position with a through hole in the middle of the blanking sphere 7057 is aligned with a central spraying block 7053, enabling the fuel gas in the central spraying block 7053 to be transmitted into the outer spraying block 7052 through the blanking sphere 7057, a connecting pipe 7054, and a telescopic pipe 7055 and ignited by an igniter 701, so that the flame can be ejected outside, increasing the range of flame ejection. The flame can be ejected separately and concentratedly, or dispersed and sprayed, and can be concentrated and dispersed at the same time, effectively improving the effect of flame ejection and the uniformity of heating;

[0133] Preheat the inside of the lower furnace body 302 to reach the temperature for raw material sintering and spheroidization in advance. When the raw materials fall as independent particles through the screening of a sieve plate three 3003, a sieve plate two 3002, and a sieve plate one 3001, they are burned by the flame ejection and spheroidized instantaneously. The screening of the sieve plate three 3003, the sieve plate two 3002, and the sieve plate one 3001 can disperse the raw materials, effectively avoiding the contact between the piled-up raw materials and the flame, thereby improving the effect of raw material spheroidization. When the raw materials enter the inside of the lower furnace body 302, they can be instantaneously spheroidized by the flame ejection and the internal high position, and continuous spheroidization is achieved in cooperation with the sieve plate three 3003, the sieve plate two 3002, and the sieve plate one 3001;

[0134] When a batch of raw materials is spheroidized, a motor one 306 is provided. The motor one 306 drives the spheroidized materials on the surface of a furnace bottom plate 307 to rotate and fall into a cooling system 5 for cooling.

[0135] The above has described a specific embodiment of the present invention in detail, but the described content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
