Drawings
Fig. 1 is a schematic structural diagram of a high-temperature dynamic firing furnace according to an embodiment of the present invention.
Detailed Description
The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.
Referring to fig. 1, the present embodiment provides a high-temperature dynamic firing furnace, which includes a vertical furnace body, wherein an included angle between the vertical furnace body and a vertical direction is preferably 0-45 degrees, and in fact, only an inclination angle at which material particles fall freely can be achieved. The inner chamber of the vertical furnace body is sequentially divided into a glue discharging section 1, a sintering section 2 and a cooling section 3 from top to bottom.
The sintering section 2 is a main forming stage, wherein a fire nozzle 4 for igniting and providing ambient temperature is arranged, material particles are heated to a target temperature, and meanwhile, impurities such as metal scraps and the like in the material particles are melted, so that the processing requirement is met.
The binder removal section 1 is used for removing the binder in the material before firing at a certain temperature, and the temperature requirement can be controlled by an additional heater or directly provided by a fire nozzle 4 in the firing section 2.
In addition, the lower end of the vertical furnace body is provided with an air passage blowing upwards, material particles float in the vertical furnace body under the action of the air flow 5, and the size of the air flow 5 of the air passage is adjustable, so that the supporting force is controlled, and the falling speed of the particles is adjusted.
The cooling section 3 is used for slow cooling after sintering, and air cooling can be directly realized due to the existence of an air duct.
Be provided with sieve check board 6 between the adjacent section, seted up a plurality of sieve meshes on the sieve check board 6, the material granule leads to the fact to slow down and roll through the sieve mesh, and further, sieve check board 6 can be controlled by actuating mechanism and make reciprocating motion to improve the efficiency that the granule was sieved.
In order to avoid overlarge wind power at the bottom and undersize wind power at the upper part, the inner diameter of the vertical furnace body is designed to be gradually reduced from bottom to top so as to reduce the difference of the wind power at the upper part and the lower part.
The mesh size of the sieve grid plate 6 between the sintering section 2 and the cooling section 3 is smaller than that of the sieve grid plate 6 between the binder removal section 1 and the sintering section 2, namely, relatively speaking, material particles are easy to enter the sintering section 2 from the binder removal section 1, but are not easy to enter the cooling section 3 from the sintering section 2, so that the heating time of the particles in the furnace body is prolonged.
In conclusion, the high-temperature dynamic sintering furnace is provided with the vertical furnace body, and freely discharges materials by means of the gravity of the materials, so that the conveying device is omitted, and in addition, the rolling and the speed reduction of material particles are controlled under the action of the grid plates and the air channel, so that the material particles are fully and uniformly heated, the time of the particles in the furnace body is controlled, and the heating effect is improved.
