Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides a spiral distribution machine for a rotary hearth furnace, which overcomes the deficiencies of the prior art, and aims to solve the problem that it is difficult to ensure uniform distribution of carbon-containing pellets when feeding a general rotary hearth furnace. Putting it into the rotary hearth furnace, the distribution of the material is chaotic, resulting in a high pulverization rate; and the problems of high failure rate of the distribution machine, high energy consumption, and loud noise

Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0024] see Figure 1-3 , the rotary hearth furnace spiral distribution machine of the present invention is located at the feed opening position of the furnace roof of the rotary hearth furnace, including a conveying mechanism and a material leveling mechanism;
[0025] The conveying mechanism is located above the leveling mechanism and communicated with the leveling mechanism;
[0026] The conveying mechanism is used to receive the pellet material and evenly distribute the pellet material to the leveling mechanism, and the leveling mechanism then evenly distributes the pellet material to the hearth of the rotary hearth furnace.
[0027] see figure 1 , the conveyin...

The invention relates to a rotary hearth furnace, in particular to a spiral material distributor for a rotary hearth furnace. A conveying mechanism and a material uniformizing mechanism are included, and the conveying mechanism is fixedly connected with the material uniformizing mechanism. The conveying mechanism comprises a first conveying shell, a first motor, a first coupler and a spiral conveying rod, an output shaft of the first motor is fixedly connected with the spiral conveying rod through the coupler, and the spiral conveying rod is rotationally connected to the inner side wall of the first conveying shell. The defects in the prior art are overcome, a servo motor is adopted, the rotating speed of the spiral conveying rod and a material uniformizing rod can be controlled, so that the material feeding speed is adjusted, meanwhile, through cooperation of the material uniformizing mechanism and the conveying mechanism, pellets can be distributed and fed into the rotary hearth furnace at a constant speed, the materials in the rotary hearth furnace are treated more evenly, the material distribution action is soft, and the pulverization rate can be effectively reduced.
Description
technical field [0001] The invention relates to a metallurgical rotary hearth furnace, in particular to a spiral type feeder for a rotary hearth furnace. Background technique [0002] Metallurgical technology is to extract metals and metal compounds from ores, and then use various methods to make metal materials with certain properties. Among the existing metallurgical equipment, there are rotary hearth furnaces. The rotary hearth furnace is named for its annular hearth and rotatable bottom. Its raw materials are carbon-containing pellets made of iron ore powder and coal powder. The raw material, pelletizing and drying are added to the rotary hearth furnace, and the furnace temperature can reach about 1250-1350°C. At such a high temperature, the iron ore is quickly reduced by carbon during the rotation of the furnace bottom at such a high temperature, forming The metallized pellets are finally pushed out of the furnace by the screw discharge machine, and after cooling, they...
