Description
Technical field
The utility model is related to a kind of pellet sintering shaft furnace structure, belongs to metallurgy industry pellet sintering shaft furnace equipment skill
Art field.
Background technology
Metallurgy industry, in pellet production, shaft furnace is common equipment, situations such as occur dross, sizing in body of heater, it is necessary to
Stop production, personnel enter Working in confined space.
About 1000 DEG C or so of shaft furnace in-furnace temperature, the short time stops production, and internal temperature is high, and heat radiation is serious.
Shaft furnace is tubular solid kiln, and up/down perforation, waste gas is blown into body from body of heater middle part, and cooling wind is blown into stove from bottom
Body, cooling air duct line length, without other wind-supplying mouths.
7 meters high or so in body of heater, drop is big.Water beam is typically mounted at the middle part of body of heater, for accelerating temperature in furnace
Cooling.When body of heater is overhauled, also there is peace in the especially maintenance of water beam, it is necessary to climbing ladder, upper and lower operation back and forth, wastes time and energy
Full hidden danger.
Utility model content
The utility model purpose is to provide a kind of pellet sintering shaft furnace structure, and simple structure facilitates the maintenance of body of heater to make
Industry, it is safe and reliable, solve problem present in background technology.
The technical solution of the utility model is：
A kind of pellet sintering shaft furnace structure, comprising body of heater, sintering zone, cooling zone, bocca, cooling wind inlet, furnace shell,
Pelletizing feed import, water beam and plugging device, body of heater are integrally cylindrical in shape, and the top of body of heater is provided with pelletizing feed import, the bottom of body of heater
Cooling wind inlet is provided with, bocca and Shui Liang are provided with the middle part of body of heater, the outside of body of heater is provided with furnace shell, and the inside of body of heater is provided with stove
Thorax, the top of burner hearth is sintering zone, and the bottom of burner hearth is cooling zone, and the body of heater of the Shui Liang sides is provided with square opening, described
Square opening on body of heater is provided with plugging device, and the plugging device includes plugging plate, fixing bolt, high-alumina brick, angle steel and skirtboard,
Square opening surrounding builds high-alumina brick by laying bricks or stones, and angle steel is fixed above square opening, and the skirtboard is in three-back-shaped, and skirtboard is provided with multiple equal
The bolt hole of even arrangement, skirtboard is welded on the furnace shell on the outside of square opening, and plugging plate is fixed on skirtboard by multiple fixing bolts
On, the furnace shell is steel structure frame.
Square opening and burner hearth insertion on the body of heater.
The brickwork joint of the high-alumina brick that the square opening surrounding is built by laying bricks or stones is less than 2mm.
Using the utility model, during body of heater upkeep operation, when especially overhauling water beam, packaging system is opened first, so
Staff enters burner hearth by square opening afterwards, directly carries out maintenance activity to water beam, it is no longer necessary to entered by body of heater mouthful staircase.
Maintenance is finished, and is blocked square opening using plugging device, does not interfere with the using effect of shaft furnace.
The beneficial effects of the utility model are：Simple structure, it is safe and reliable.The convenient upkeep operation to water beam, can shorten
Overhauled for 1/3 time.Facilitate personnel to pass in and out body of heater, it is no longer necessary to be entered by fire door staircase, back and forth the upper and lower operation of climbing ladder, eliminate peace
Full hidden danger.
