[0001] The application belongs to the technical field of chain grate machine material distribution, and particularly relates to a uniform material distribution device for a chain grate machine. BACKGROUND

[0002] The process for treating metallurgical zinc-containing iron dust slurry by a rotary hearth furnace direct reduction method is that the zinc-containing iron dust slurry is mixed with a binder and a carbon-containing raw material, then balling is performed through a disc balling machine, and then the balling is sent into a chain grate machine through a material distribution device for drying, and then the dried balling is distributed into a rotary hearth furnace for high-temperature roasting to be reduced into metallized balling, and finally the reduced zinc vapor is recovered by a flue gas system. In the process, whether the material distribution device can uniformly distribute the balling into the chain grate machine is a key factor affecting whether the balling can be fully dried subsequently. However, the chain grate machine material distribution device commonly used in the prior art is generally a shuttle material distribution machine, which, in use, transports the material to a feeding wide belt through reciprocating movement, and then the feeding wide belt transports the material to a roller screen, and finally the material enters the chain grate machine. However, the reciprocating distribution mode is prone to cause empty material area and thick material area on the wide belt, so that the material cannot be uniformly fed into the chain grate machine, and the drying effect is affected.

[0010] The distributor is a plurality of and is uniformly fixed on the flat material scraper, and the plurality of distributors and the wide feeding belt are arranged in parallel, and a second gap is arranged between the plurality of distributors and the wide feeding belt.

[0011] Further, the single-trip distance of the shuttle feeder during reciprocating motion is 60%-70% of the width of the wide feeding belt.

[0012] Further, the height of the first gap is 4-10 cm, and the height of the second gap is 6-18 cm.

[0013] Further, the distributor is arranged on the flat material scraper away from the side of the roller screen.

[0014] Further, the distributor includes a fixed rod and two distribution plates, and the two distribution plates are fixed on opposite sides of the same end of the fixed rod so that the distributor has an arrow shape, and the other end of the fixed rod is fixed on the flat material scraper.
