Chute design is a staged, and the chute angle [alpha] is 30 degree.Through chute, material movement slows down sintering deposit, is similar at slide sieve to move on finished belt, short grained sintering deposit flows down earlier and arrives on the belt, belt is played a place mat effect, and oarse-grained knot ore deposit falls again, and the path of motion in knot ore deposit is changed into along the notch cuttype chute by vertical landing and flowing down.
The β angle is the quiet angle of repose of material, and angle of repose is meant material when a specified height freedom falls equably, the maximum slope angle of the stable taper stockpile that keeps of formed energy, i.e. the stockpile surface of stacking and the maximum angle between the horizontal surface naturally.It has reflected the flowing power of material, and the more little then flowing power of angle of repose is good more.The quiet angle of repose β of sintering deposit is generally the 40-45 degree, and the extension dotted line at β angle is the buildup line of chute.A significant dimensions of design chute volume be with the buildup line be benchmark to the distance of chute part top hypotenuse be the maximum lumpiness size of material 3-5 doubly, we generally get 720 millimeters, the width of chute be the transport plane width 0.65-0.85 doubly.The inclination angle of chute is a considerable parameter, if value is excessive, then buildup is few, does not have the effect of material abrasive material, if value is too small, then increases a chute volume and a unnecessary carry lotus.We generally get inclination alpha=β-(10～15) ° in actual design, generally getting inclination alpha for the chute of sintering deposit is 30 degree.The wear-resisting pocket of rich chromium cast iron is installed in the chute the inside, and the angle that back pocket arrangement is installed forms the β angle.Rich chromium cast iron belongs to Cr series white cast iron, is to contain the cast iron of chromium more than 12%, because the adding of chromium element, its resistance to abrasion and impact-resistant performance are much higher.
Supporting plate 5 described in the utility model is welded on the below of chute 3, and welding one vertical bar striker plate on the supporting plate 5, supporting plate are apart from belt centerline 300mm, and gusset is strengthened in welding between vertical bar striker plate and the supporting plate.
Reflecting plate 1 described in the utility model is apart from cylinder Down Highway 300-400mm, and the distance between reflecting plate 1 and the supporting plate 5 is 720mm.The effect of reflecting plate and supporting plate is and slows down the material running velocity.
The used rich chromium cast iron of the wear-resisting pocket of rich chromium cast iron described in the utility model is a Cr series white cast iron, contains chromium more than 12%.
After this device is installed in the material storehouse, variation has taken place in the running orbit of material, become along the notch cuttype chute by original vertically falling and to flow down, specific descriptions are: material from the driving drum impelling to reflecting plate, reflecting plate and chute form certain space can preserve the thin material of a part, forms the 1st buildup district; Material is refracted on the wear-resisting pocket by reflecting plate again, is flow on the supporting plate of chute below by wear-resisting pocket again, owing to welded a vertical bar striker plate on the supporting plate, the 2nd buildup district formed on so straight baffle plate and chute bottom; Last material is flowed on next bar belt feeder by supporting plate.
After sintering deposit installed through this, path of motion was changed into along the notch cuttype chute by vertical landing and flowing down.After knot ore deposit path of motion changes, reduce and finish breaking into pieces of ore deposit, reduce and finish the chip index in ore deposit.After this device is installed simultaneously, reduced sintering deposit to impulsive force to belt, can prolong the service life of belt greatly, particularly use on hot barrow band, because short grained place mat effect is arranged, reduced the probability of belt scaling loss, belt life can prolong more than 3 times, greatly reduces the belt cost.In addition, the formation in two buildup districts has reduced the direct wearing and tearing of sintering deposit to this device, the service life of guaranteeing this device.
The utility model subtracts the advantage of the wear-resisting chute device of grain:
1, easy for installation: since the wear-resisting pocket of rich chromium cast iron be bolt up on chute, only need on chute, punch during installation, bolt up gets final product.
2, long service life: because this chute design is a staged, material forms material abrasive material phenomenon in chute, and this chute device is installed and once can be used the long period.
