Abstract
The utility model discloses an improved rotary kiln which is suitable for producing manganese-rich slag. An iron outlet (3) is arranged on a cylinder body (4) which has a certain distance from a slag outlet (1), the iron outlet (3) comprising a plurality of iron outlet pores and is sealed with refractory mortar, a check ring (2) is arranged on the inner side of the iron outlet (3) in a matched mode, and molten iron and slag are respectively discharged from the iron outlet (3) and the slag outlet (1). The rotary kiln can effectively separate slag and iron, is more beneficial to manganese-rich slag to increase manganese and reduce iron and increases an operating rate.
Description
Technical field
The utility model relates to a kind of improved rotary kiln, is suitable for the production of rich manganese slag.
Background technology
On January 31st, 2010, the applicant applied for once that a key name was called the patent of invention of " rotary kiln is exempted from the coke method and produced rich manganese slag ", and application number is 201010120319.X.This invention relates to rotary kiln replacement blast furnace, electric furnace and converter produces rich manganese slag, has outstanding advantages efficient, energy-saving and environmental protection.
Rotary kiln is made up of cylindrical shell, supporting device, transmission mechanism.Existing rotary kiln is used for roasting, the preheating of manganese ore, need not to improve, but is used to produce rich manganese slag, because slag iron causes separation difficulty easily all from the exhaust end discharging, influences the concentration effect of manganese element and falls the iron effect.
The utility model content
The rotary kiln of being made up of cylindrical shell, supporting device, transmission mechanism is owing to have only a discharge opening, and when being used to produce rich manganese slag, slag iron all from the exhaust end discharging, causes separation difficulty easily, the concentration effect that influence manganese element with the iron effect is fallen.
The technical solution of the utility model is: apart from the position of slag notch certain distance an iron notch is set at cylinder of rotary kiln, iron notch can be made up of a plurality of holes of tapping a blast furnace; Back-up ring of the inboard supporting installation of iron notch.Iron notch seals with refractory mortar.Manganese ore and reductive agent, flux melting and reducing in kiln.When rotary kiln running for some time, when molten iron runs up to some amount before back-up ring, open refractory mortar and seal, molten iron is discharged from iron notch.Slag is then discharged from slag notch continuously.
The utility model is owing to be provided with an iron notch and back-up ring of supporting installation on cylinder of rotary kiln, make molten iron and slag respectively in iron notch and slag notch discharging, realize that slag iron effectively separates, helping rich manganese slag increases manganese content, reduces iron level and high-manganese pig iron reduction manganese content, increases iron level, thereby further improves the quality of products and operating rate.
Description of drawings
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the structural representation according to a kind of concrete structure of utility model proposition.
Embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
Rotary kiln after the improvement still is made up of cylindrical shell (4), supporting device (6), transmission mechanism (5).Different is apart from slag notch (1) 1.2m place an iron notch (3) to be set at 2.8 * 34m cylinder of rotary kiln (4); Iron notch (3) is circular, diameter 5cm; The inboard back-up ring (2) of iron notch (3) highly is 30cm.
When producing rich manganese slag, seal iron notch with refractory mortar earlier; Manganese ore and coal/breeze, flux melting and reducing in cylindrical shell (4); Slag is crossed back-up ring (2) and is discharged slowly from slag notch, through pure water cooling, becomes rich manganese residue product; Molten iron was opened iron notch (3) and is emitted molten iron near back-up ring (2) when height, through the cast cooling, became the byproduct high-manganese pig iron.
Claims (1)
1. rotary kiln of producing rich manganese slag, form by cylindrical shell (4) and supporting device (6), transmission mechanism (5), feature of the present utility model is: the cylindrical shell (4) at rotary kiln is provided with an iron notch (3) apart from slag notch (1) a distance, and iron notch (3) can be made up of a plurality of holes of tapping a blast furnace; The inboard back-up ring of supporting installation of iron notch (3) (2).
