Abstract
This invention is an experimental iron concentrate pelletizing device. In the pelletizing disk there are three active scrapers at different location, which are vertical to the disk. The central scraper is located at the center of the pelletizing disk. The hemline scraper is located at the top the disk near to the disk border. The guide scraper located at the first quadrant near to the 1/3 to 2/3 position of the radial. At the top of the disk there are mixer, feeder, water tank and water pump. The material could move to the mixer through the belt conveyer. And the pump and the atomizer send water to the machine in gas. When the ball reach the needed scale it will be eject automatically and through the chute baffle to the raw ball receiver. The equipment of this invention could pelletize ball continually and enhance the pelletizing efficiency. It has stable particle size and product quality.
Description
Technical field
The invention belongs to the ferrous metallurgy field, relate to a kind of experiment type iron concentrate continuous palletizing device and method.
Background technology
High basicity sinter is to generally acknowledge ideal blast furnace ironmaking burden structure with addition of the acidic oxidation pellet.China's iron ore deposit is abundant, but most of iron ore is low grade ore and complex multi-metal ore deposit, needs could satisfy after the fine grinding sorting obtains iron ore concentrate, the further moulding agglomeration of iron ore concentrate the requirement of blast-furnace smelting.Sintering process and pelletizing method are the main moulding agglomeration methods of two classes of present industrial application.Granule iron concentrate is difficult to sintering because of fine size, and the suitable pelletizing method that adopts is handled.Because China's iron ore deposit distribution is wide, of a great variety, character is complicated, cause that the granularity of iron ore concentrate and composition difference are big, to make ball poor performance, balling ratio low etc., adopt any iron ore concentrate to produce all need to carry out the laboratory before the oxide pellet and make the ball performance test research, make ball production for industry foundation is provided.Yet, the used ball method of making in laboratory is interruption and makes the ball method both at home and abroad at present, adopt to be interrupted and to make result that the ball method obtained that the directive function that ball produces is made in industry continuously is limited, when to such an extent as to many newly-built pelletizing plants go into operation or when pelletizing plant begins to adopt certain new raw material, plenty of time need be spent again, what have reaches the several months, and the ball process is made in debugging repeatedly, has wasted a large amount of human and material resources and financial resources.Therefore developing a kind of experiment makes the ball method continuously and thinks that industry makes ball production and provide robust techniques according to having very important realistic meaning.
Summary of the invention
The purpose of this invention is to provide a kind of experiment type iron concentrate can make the device of ball continuously and utilize this device to make the method for ball.Following elder generation is described the structure of this device.
The device that experiment type iron concentrate can be made ball continuously mainly comprises, following equipment:
1 makes the ball disk
Usually experiment type pelletizer mainly is made up of disk, transmission mechanism, and device of the present invention is made up of disk, transmission mechanism, movable scraping plate and the chute that connects material etc.According to material condition and test requirements document, making the inclination angle and the rotating speed of ball disk can regulate, and the present invention's different positions in disk is equipped with three and the vertical scraper plate of card, and one is center scraper, be positioned at ball disk center, angle can be adjusted between second quadrant, 45 degree at first quartile 45 degree; Second is the base scraper plate, is positioned at ball dish upper end, and near ball plate edge, angle can be in 15 degree adjustings about medullary ray between first and second quadrant; The 3rd guide scraper plate is positioned at 1/3rd to 2/3rds places of first quartile, ball dish radius, and angle can be in the adjusting to 60 degree of 30 degree.Scrape Board position, angle by adjustment, make and make in the ball process mother bulb and constantly form and grow up, behind green-ball granularity 12～15mm, under the effect of centrifugal force and scraper plate, discharge automatically and make the ball disk, constantly the new mother bulb that produces continues to grow up, and pelletizer can be made ball continuously.
2 mixing containers and electronic continuous-feeding device
Make ball disk top mixing container and continuous-feeding device are housed, material feeder places the mixing container below, and the ball compound of making in the mixing container feeds continuously through electronic material feeder and makes the ball disk.Reach the purpose of regulating the blanking amount by the distance of regulating continuous-feeding device rotating speed and adjust between hopper and the material feeder, also can adjust the position of blanking point according to making the ball needs.
3 electronic priming apparatus
Make ball disk top water storage tank and booster water pump also are housed, by water pump and spraying gun water is joined in the pelletizer in vaporific mode, can select different water spray positions as required, simultaneously can make the ball amount of water by the adjusting of diffusing valve size that water tank is returned in control.
4 packaged type compound charging belt machines
The ball compound of making that mixes is delivered in the mixing container continuously by conveyor movably.
5 finished product green-ball receiving devices
The qualified green-ball of discharging automatically from make the ball disk enters the green-ball material receiver through the chute baffle plate.
The method of apparatus of the present invention when the continuous production pelletizing is as follows:
1 at first incites somebody to action, and the ball compound of making of batch mixes is transferred to by packaged type charging belt machine in the mixing container of pelletizer top, and feed-tank adds entry simultaneously.
2 start pelletizer, by frequency transformer the rotating speed of pelletizer is transferred to suitable speed, start material feeder and regulate the blanking amount and the feed opening position to the pelletizer blanking, opening the water pump adjusting again makes the ball confluent and gives water spot, begin to make continuously ball, in making the ball process, regulate feeding coal at any time according to the particular case of making the ball process, the feeding point, confluent and give water spot, make pelletizer continuously produce epigranular, stay-in-grade green-ball, when green-ball is grown up to certain particle size, will from balling disk (-sc), discharge automatically, enter into the green-ball material receiver by the chute baffle plate.
3 when making the chou bundle, stops water pump and electronic material feeder earlier, cleans out residue green-ball and concentrate in the pelletizer then.Stop pelletizer and rotate, finish and make the ball process continuously.
Present device is simple, can realize making continuously ball, improves the efficient of making ball, and the spherolite degree of producing is even, steady quality.
