The sintering circulating cooling machine removes a double-layer dump valve and a slewing trolley and is provided with the slide fastener machine, the vibration feeder and the cement air duct to convey the bulk material, thereby effectively reducing emergency shutdown time, improving operating rate and stabilizing sintering practice.
Description
Technical field
The utility model relates to a kind of ironmaking equipment, especially for the central cooler of cooling sintering deposit, belongs to the smelting equipment technical field.
Background technology
The employed sintering deposit of blast furnace process, through behind the sintering machine sintering when tail unloads about 700～800 ℃ of temperature, and actual serviceability temperature of smelting will drop to about 150 ℃, therefore, the cooling of sintering deposit is a very important ring in SINTERING PRODUCTION technology.What the cooling of sintering deposit was used is to utilize circular cooler (being central cooler) to carry out machine to cool off outward for general a kind of method very, circular cooler is made of the chassis that a plurality of mutual head and the tail connect, and chassis is realized cooling through air blast or exhausting in the running on circular orbit.For collecting the unrestrained down bulk cargo of central cooler bend discharge pit and trolley track, have balk cargo collecting device at central cooler bend discharge pit and trolley track, at present, the central cooler balk cargo collecting device as shown in Figure 5, it adopts bulk cargo collection funnel 6 to collect bulk cargo, be discharged on the helicoid dolly 14 by Double-deck cinder discharge valve 13, then buildup transported to belt feeder 9, the bulk cargo collection funnel of central cooler also is the bellows of central cooler.The problem that this device exists is 1, bulk cargo is more serious to the collection funnel wearing and tearing, collection funnel often occurs and leaks the material phenomenon, and bellows can seriously leak out when collection funnel leaked material, influenced the cooling effect of central cooler.2, Double-deck cinder discharge valve is discharged to collected bulk cargo on the helicoid dolly.Material leaks out because of grinding leak in Double-deck cinder discharge valve regular meeting, has a strong impact on the cooling effect and the normal discharging of central cooler.3, rotary machinery is accident Chang Fadian, and dolly maybe can not run well because of sliding down and cause bulk cargo collection funnel buildup too many, influences central cooler cooling and by forced-stopping machine, has a strong impact on production.Because of funnel leakage material, Double-deck cinder discharge valve, rotary machinery often break down, maintenance cost and spare part cost height, and waste great amount of manpower and material resources.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of structure that at central cooler bend discharge pit machine for zipper and oscillating feeder is set, the cement air channel is set under trolley track is provided, thereby avoids leak the material air leakage phenomena, reduced the sintering circular-cooler that bulk cargo is collected of being convenient to of maintenance cost.
The alleged problem of the utility model is that following technical scheme solves:
A kind of sintering circular-cooler of being convenient to the bulk cargo collection, comprise circular orbit in the formation, chassis and balk cargo collecting device, its special feature is: described balk cargo collecting device is made up of bend unloading part and chassis target phase two parts, wherein the bend unloading part is positioned at the track bottom of central cooler blanking point 1 side, its structure is: the bulk cargo collection funnel 6 that communicates with this section track 12, bulk cargo collection funnel bottom is provided with machine for zipper 7, be provided with oscillating feeder 8 between machine for zipper and haul belt feeder, described chassis target phase is positioned at the bottom at other positions of track, and structure is: the airtight cement air channel 5 that communicates with this section track.
The above-mentioned sintering circular-cooler of being convenient to the bulk cargo collection is provided with air-tightness door 10 in the described air channel, the doorway of air-tightness door is provided with the ramp 11 that communicates with the air channel.
The above-mentioned sintering circular-cooler of being convenient to the bulk cargo collection, described machine for zipper is two.
The utility model improves at be scattered gathering-device Double-deck cinder discharge valve quick abrasion, drawback that the rotary machinery accident is many of existing central cooler: abandon Double-deck cinder discharge valve and rotary machinery; chain machine for zipper oscillating feeder is set finishes transporting of bend discharge pit bulk cargo; the unrestrained bulk cargo in other position accumulates in the cement air channel of setting up; machine for zipper is simple in structure; for ease of maintenaince; long shutdown can not appear; the space is big in the air channel; also can not cause shutdown even there is the part bulk cargo to pile up, every half a year, cleaning once just can guarantee ordinary production approximately.Above-mentioned improvement has effectively reduced accident downtime, has improved operating rate, has stablized SINTERING PRODUCTION.Simultaneously, reduced spare part expense and equipment maintenance cost, reduced labour cost, reduced worker's labour intensity, improved the output of sintering machine operating rate and sintering deposit, the economic benefit of creating considerable, have the prospect of promoting the use of.

The specific embodiment
Referring to Fig. 1, the chassis 2 that main composition of the present utility model comprises circular orbit 12, orbits is positioned at central cooler cover 3, the chimney 4 on chassis top and is positioned at the balk cargo collecting device of track bottom.Balk cargo collecting device is made up of bend unloading part and chassis target phase two parts, and wherein the bend unloading part is positioned at central cooler blanking point 1 side, and the chassis target phase is positioned at other bottoms, position of track, and it occupies more than half annulus.
Referring to Fig. 1, Fig. 2, the structure of balk cargo collecting device bend unloading part is: track 12 bottoms are provided with bulk cargo collection funnel 6, and bulk cargo collection funnel bottom is provided with two machine for zipper 7, and 9 of machine for zipper and haul belt feeders are provided with oscillating feeder 8.Its course of work is, directly moves oscillating feeder to by machine for zipper after the bulk cargo that drops on this section is collected by the bulk cargo collection funnel, again by oscillating feeder feed track belt feeder.Machine for zipper is simple in structure, for ease of maintenaince, long shutdown can not occur, and a small amount of bulk cargo of a machine for zipper roping bend discharge pit, and the bulk cargo amount is little, has prolonged the service life of equipment.
Referring to Fig. 1～Fig. 4, the structure of balk cargo collecting device chassis target phase is: the airtight cement air channel 5 that communicates with track is set in the track bottom, be provided with air-tightness door 10 in the air channel, for ease of loading the vehicle pass-through of bulk cargo, the doorway of air-tightness door is provided with the ramp 11 that communicates with the air channel.The chassis target phase is used to collect the unrestrained down bulk cargo of track that accounts for whole track significant proportions; bulk cargo under this paragraph directly remains in the air channel; because duct space is big, can not cause shutdown even there is the part bulk cargo to pile up yet, the buildup in the air channel is cleared up once approximately half a year; install on the automobile with forklift and to transport; just can guarantee production requirement, and not have leakage material, air leakage phenomena, thereby effectively avoid accidental shutdown; improve operating rate, stablized SINTERING PRODUCTION.
