The rotary hearth furnace in metallurgical industry is mainly used for pellet sintering, direct reduction and other processes, pellets are manufactured before entering the furnace, then the pellets are distributed to the bottom of the furnace by a distributing machine, and in order to ensure sintering quality and yield, the distribution is uniform and the thickness can be controlled. The bottom of the rotary hearth furnace is annular, the radius difference of the inner ring and the outer ring is large, the linear velocity of the outer ring is large, the material distribution area is large outwards, and the material distribution amount in unit time is correspondingly increased. The existing distributing device is arranged above a feed port of a rotary hearth furnace along the radial direction of the rotary hearth furnace, and material balls are vibrated to fall to the bottom of the rotary hearth furnace through a motor and a vibration exciter on a screen box, so that even if the width of a feed port of the distributing device is different along the radial direction of the rotary hearth furnace, the whole bottom of the rotary hearth furnace is difficult to uniformly spread, and the vibration frequency and the width of the feed port are required to be continuously adjusted; it is more difficult to adjust the thickness of the cloth to increase the yield. Because the material distributing device needs to vibrate for distributing materials and is elevated on the feed inlet of the rotary hearth furnace, the smoke and heat at the feed inlet of the rotary hearth furnace are easy to escape; the temperature at the feed inlet is close to 1000 ℃, the bottom of the distributing device needs a water-cooling interlayer to prevent baking deformation, and unsafe factors are increased; the adverse effects of the distributor vibration and furnace resonance on the refractory material are also considered.

two sides of the distributing device 1 are respectively provided with a supporting rod 3; the adjusting rods 4 are fixed on two sides of a feed inlet of the rotary hearth furnace 6, the adjusting rods 4 are detachably fixed with the supporting plate 2, and the height of the supporting plate 2 is adjustable.
The adjusting rod 4 is fixed with the supporting plate 2 through the nut 5, the upper portion of the supporting plate 2 is provided with a gap 7 matched with the diameter of the supporting rod 3, and the supporting rod 3 is placed in the gap of the supporting plate 2.
The external dimension of the bottom end of the distributing device 1 is matched with the dimension of the feed inlet of the rotary hearth furnace 6.
The outer layer of the distributing device 1 is made of heat-resistant steel, and the inner layer is lined with refractory materials.
The position of the nut 5 on the adjusting rod 4 can be adjusted up and down, so that the height of the adjusting supporting plate 2 is driven to be adjusted.
The supporting plate 2 is L-shaped, and the notch 7 on the supporting plate is semicircular.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses a distributing device comprises a distributing device and a height adjusting mechanism, is inserted into the rotary hearth furnace when in use, and accumulates materials in the distributing device through a conveyor, and seals the smoke and heat of the rotary hearth furnace in the rotary hearth furnace, so that even if the materials contain powder, the materials can not pollute the outside in the falling process, and the working environment is greatly improved; because the materials are accumulated in the distributing device, when the rotary hearth furnace rotates, the materials are dragged to move along with the bottom of the rotary hearth furnace at the bottom of the rotary hearth furnace, and the materials in the hopper can be supplemented in time along with the movement at the place with more materials distributed at the outer ring, so the materials are distributed more uniformly; the thickness of the material distribution is related to the height between the material distributor and the furnace bottom, and the height between the material distributor and the furnace bottom can be adjusted, so that the thickness of the material can be adjusted; the utility model discloses a distributing device skin is heat-resisting steel material, and inlayer lining refractory material can bear the high temperature, need not the water-cooling, can not have dangers such as leaking.
