Abstract
A kind of Anti-blockage type blast furnace middle hopper, its body comprises oblique sidewall and other straight sidewalls; The discharge gate of middle hopper establishes turnover panel to be opened/closed; It is characterized in that, the oblique sidewall of described middle hopper and straight sidewall are corresponding thereto respectively steel structure frame, arrange some running rollers along its length in steel structure frame, and sheathed belt, form belt conveyor.The utility model makes middle hopper avoid the phenomenon that gets stuck, and ensures that the supply of furnace charge improves the stability of equipment, makes operation of blast furnace high-quality, low consumption, environmental protection.
Description
Technical field
The utility model belongs to blast-furnace technique field, particularly a kind of Anti-blockage type blast furnace middle hopper.
Background technology
Current Large Scale BF is with the obvious advantage in energy consumption, environmental protection, output etc., and along with the progressively expansion of newly-built blast furnace heat size, the pressure of raw material supply also progressively increases.The stainless 2# blast furnace of Baosteel makes conveyor material loading, and furnace charge enters middle hopper after being weighed respectively by the burnt groove in ore deposit under groove, then passes through the charging system of main Belt Conveying to furnace roof by middle hopper.Current middle hopper has ore deposit I sorrowful II side and totally 4, II side, burnt I side respectively, be under groove furnace charge batch weight weigh after deposit feed bin temporarily, be also a link indispensable under groove and between charging system.
The feature of blast fumance is continuous, when middle hopper occurs getting stuck phenomenon, it is made to keep discharge unimpeded if can not process in time, the raw material supply of blast furnace will be affected, if the treatment time is longer, checking in stove, is needed to control combustion intensity, have a strong impact on rhythm of production, stockline declined the gas fluid distrbution that deeply even can destroy in stove, affected furnace condition recovery.
Summary of the invention
The purpose of this utility model is to design a kind of Anti-blockage type blast furnace middle hopper, makes middle hopper avoid the phenomenon that gets stuck, and ensures that the supply of furnace charge improves the stability of equipment, makes operation of blast furnace high-quality, low consumption, environmental protection.
For achieving the above object, the technical solution of the utility model is:
A kind of Anti-blockage type blast furnace middle hopper, its body comprises oblique sidewall and other straight sidewalls; The discharge gate of middle hopper establishes turnover panel to be opened/closed; It is characterized in that, the oblique sidewall of described middle hopper and straight sidewall are corresponding thereto respectively steel structure frame, arrange some running rollers along its length in steel structure frame, and sheathed belt, form belt conveyor.
Preferably, the turnover panel of described middle hopper discharge gate is electric rotating plate.
The beneficial effects of the utility model:
The utility model makes originally fixing discharge gate into steel structure frame; The oblique sidewall of middle hopper and relative straight sidewall thereof are equipped with running roller respectively; Running roller solid matter replaces original body of wall; Running roller covers belt.
1, adopt the design of running roller and belt can effectively reduce discharge resistance, stop the phenomenon that gets stuck, guarantee blast furnace stable smooth operation.
2, the discharge gate rolled not easily gathers powder and forms bonding, ensures to meet the demands into stove crude fuel grade, is conducive to improving permeability of stock column in stove.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
See Fig. 1, a kind of Anti-blockage type blast furnace middle hopper 1 of the present utility model, its body comprises an oblique sidewall 11 and other straight sidewalls 12,12 '; The discharge gate 13 of middle hopper establishes turnover panel 2 to be opened/closed; The oblique sidewall 11 of described middle hopper and straight sidewall 12 are corresponding thereto respectively steel structure frame, arrange some running rollers 3,3 ' in steel structure frame along its length, and sheathed belt 4,4 ', form belt conveyor.
Preferably, the turnover panel 2 of described middle hopper 1 discharge gate 13 is electric rotating plate.
After furnace charge enters middle bucket feed bin, and frictional coefficient is relatively little between belt, land under self gravitation effect, the frictional force simultaneously produced between furnace charge and belt becomes the motivating force driving running roller to rotate, thus drive belt to rotate, can accelerate furnace charge further, the powder in raw material, foreign matter etc. are not easy to assemble, and ensure that furnace charge falls into main belt from discharge gate smoothly.
The utility model effectively avoids the middle phenomenon that gets stuck that struggles against, and guarantees blast furnace stable smooth operation.
