Abstract
An anti-clogging middle slag tank belongs to a melting steel slag treatment device and particularly relates to a steel slag wind-breaking and granulating device. The device is formed by connecting a tank body and a chute, fire-resisting materials are arranged in the tank body and the chute, lifting lugs and a hanging ear are arranged outside the tank body, and an overflow gate is arranged below the tank body and connected with the chute. The middle slag tank is characterized in that the cross section of the chute is an inverse trapezoid with a wide top and a narrow bottom, the side part of the chute is expanded upward gradually from the bottom by the angle of Gamma, the cross section of the chute is larger than the caliber of the overflow gate, the bottom of the chute is connected with the lower part of the overflow gate and inclines downward by the angle of Alpha, and the cross section of the chute expands gradually from the inflow port to the outflow port by the angle of Beta. The anti-clogging middle slag tank has the advantages that the clogging of the middle slag tank and the chute is solved, the replacing frequency of the middle slag tank and the chute is reduced, the residue of the chute is easy to clear, the operating rate of the steel slag wind-breaking and granulating device and the steel slag wind-breaking and granulating treatment rate are improved, the hot slag spilling amount is greatly reduced, a big amount of deslagging and pollution discharging cost is lowered, useful resources are recycled, and conditions for the application of steel slag wind-breaking and granulating industrial technology are created.
Description
Technical field
The utility model belongs to the molten steel slag treatment unit, relates in particular to the steel slag wind-crushing granulating device.
Background technology
Molten steel slag wind granulation is a novel slag treatment process, for the benefit of reclaims steel scrap in the slag, utilizes in the slag other element to create favourable condition.After production practice showed that bessemer furnace slag is through the broken processing of wind, its CaO content was lower than 2%, can directly make building materials and use.Current, the steel slag wind-crushing granulating device is to be connected and composed successively by middle slag ladle, spraying gun and pond.When handling slag, fusion is transported to the tundish top by slag ladle and is poured in the middle slag ladle, and overflow port, the chute through middle slag ladle flows out again; pelletizer ejection high velocity air breaks up slagging with slag and drips; granulating is shunk in cooling in air, and falling into the pond becomes spherulitic wind disintegrating slag, for recycling.Having defective is the cross section of the overflow port bore of middle slag ladle greater than chute.The chute cross section is a rectangle, and the chute bottom is straight along its length; During deslagging, slag ladle in the middle of part skull, clinker enter in the slag ladle.When handling slag, the less clinker of some lumpiness flows to into middle slag ladle overflow port, chute with slag, and middle slag ladle overflow port, chute are stopped up, and the broken processing of wind can't be proceeded.Usually be a slag ladle slag only handle little by little will occur in the middle of slag ladle stop up, remaining slag is got only hot application and is handled in the slag ladle.Equipment operation rate and granulated processed rate are low; The hot application slag takes up an area of, processing costs height, waste resource.
Summary of the invention
In order to overcome the defective that prior art exists; the purpose of this utility model provides the middle slag ladle of a kind of anti-clogging plug; solve the overflow port, the chute blockage problem that exist in the slag granulated processed process; improve equipment operation rate and steel slag wind-crushing granulated processed rate, make the steel slag wind-crushing pelletizing technology realize industrial applications effectively.
Slag ladle in the middle of the anti-clogging plug is connected and composed by tank body and chute, establishes refractory materials in the two, tank body peripheral hardware hanger and hangers, tank body is divided into overflow port, is connected with chute, characteristics are that the chute cross section is " trapezoidal " wide at the top and narrow at the bottom, and the chute sidepiece upwards enlarges the γ angle gradually by the bottom; The chute cross section is greater than the overflow port bore, and the chute bottom is connected with the overflow port bottom, and downward-sloping α angle; Chute cross section gravity flow import enlarges the β angle gradually to spout.Slag flows through chute, and it is smooth and easy to flow, and does not stop up, and steel slag wind-crushing is carried out smoothly.
Compared with prior art, advantage is to have solved middle slag ladle and chute blockage problem, slag ladle replacing number of times in the middle of reducing; The chute residue is removed easily, has improved steel slag wind-crushing granulating device operating rate, improves steel slag wind-crushing granulated processed rate, significantly reduces the hot application quantity of slag, reduces huge deslagging and effluent charge and uses; Recycled useful resources, for steel slag wind-crushing granulation technique industrial application has been created condition.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is the steel slag wind-crushing granulation with middle slag ladle structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the side-view of Fig. 1.
Embodiment
By Fig. 1, Fig. 2, Fig. 3 as can be seen, the steel slag wind-crushing granulation is connected and composed by tank body 1 and chute 2 with slag ladle in the middle of the anti-clogging plug, establishes refractory materials in tank body 1 and the chute 2.Tank body peripheral hardware hanger 4 uses for handling; If hangers 5 uses for the inclination tank body.The chute cross section is " trapezoidal " wide at the top and narrow at the bottom, and chute 2 bottoms tightly are connected with the overflow port 3 that tank body 1 is divided into, and from tank body 1 downward-sloping α angle, 5 °≤α≤15 °, the stream slag is smooth; Chute cross section gravity flow import enlarges the β angle gradually to spout, 1 °≤β≤3 °; The chute sidepiece upwards enlarges the γ angle gradually by the bottom, 5 °≤γ≤10 °, makes things convenient for deslagging.Overflow port 3 connects with chute 2, and overflow port 3 bores are less than the cross section of chute 2.
Claims (4)
