Abstract
The utility model relates to a movable type arc-shaped gas hood of a silver making converter mouth, which comprises a hood body and horizontal and vertical steel pipes used for fixing and supporting the hood body. The utility model is characterized in that the plane at the lower mouth of the gas hood is a slope with low outside and high inside, an acute angle alpha is formed between the slope and the plane, and the outer side surface of the gas hood is processed in an arc shape. The utility model has good sealing performance and no dust loss at the converter mouth, greatly improves the operating environment, and increases economic benefits.
Description
(1) technical field: the utility model relates to a kind of flue dust retracting device of smelting industry, specifically is the movable arc petticoat pipe of silver metallurgy converter mouth.
(2) prior art: be used for the baby Bessemer converter fire door petticoat pipe of silver metallurgy industry at present, wherein have one type to be rotary type, promptly petticoat pipe can save back rotation with the rotation that vertical steel pipe is connected along level.Its advantage of such petticoat pipe is very outstanding, concludes to get up to have: the one, and simple in structure, rolled steel dosage is seldom; The 2nd, when fire door is reinforced, petticoat pipe can be removed from fire door, thereby conveniently in stove, be added bagged material with the form of hanging by fire door with hoist ceiling crane, therefore reinforced mechanization degree is very high, and hand labor intensity is corresponding to be reduced greatly.But its shortcoming also is quite tangible, and the petticoat pipe partial design that mainly shows as the fire door top is very unreasonable.According to the situation of present understanding, the petticoat pipe of fire door top is designed to have an area of head dummy mostly, and it is suitable for reading to be circular, and end opening is a square, for preventing the fire door thermal-flame petticoat pipe is burnt out, and the petticoat pipe end opening of generally designing is all far away from fire door.But so just greatly reduce the sealing property of petticoat pipe, the volume of smoke (argentiferous about 20%) that makes fire door come out flies away everywhere, and this has not only wasted national resources, and has worsened the execute-in-place environment, is unfavorable for blast-furnace man's physical and mental health.
(3) summary of the invention: the purpose of this utility model just provides a kind of good seal performance, and fire door does not have flue dust and scatters and disappears, and has improved the movable arc petticoat pipe of silver metallurgy converter mouth of operating environment.
The movable arc petticoat pipe of silver metallurgy converter mouth of the present utility model, comprise cover body and fixed support cover body anyhow to steel pipe, it is characterized in that: described petticoat pipe bed is outer low and inner high inclined-plane, is an acute angle a between its inclined-plane and the horizontal plane; The lateral surface of petticoat pipe is processed into arc.
Described petticoat pipe end opening inclined-plane is trapezoidal, and its area is 13-16 a times of converter mouth area.
The arc radius R of described petticoat pipe lateral surface is 3800-3900mm.
Have on the lateral surface of described petticoat pipe for skimming, take a sample, observe the working hole of usefulness.
The utility model is compared with original petticoat pipe, has the following advantages: the one, and petticoat pipe is pressed close to fire door makes that its air leak rate of air curtain is little, sealing property is very high, fire door smokelessly scatters and disappears,, and original petticoat pipe is far away apart from fire door, air leak rate of air curtain is big, and sealing property is very poor, and fire door has volume of smoke to scatter and disappear.The 2nd, because of the side curved plate being arranged, not only avoided the direct heat radiation of fire door high-temperature flue gas, and avoided the furnace high-temperature silvering solution to spill and hurted sb.'s feelings as " baffle plate ", protected to a great extent therefore that the blast-furnace man's is healthy.And original petticoat pipe is higher because of end opening, and far away from fire door, does not have this effect.
The utility model is through on probation, and the petticoat pipe mouth smokelessly scatters and disappears; Petticoat pipe is not burnt out distortion yet, illustrates that this has good sealing property and resistance to elevated temperatures.
Through preresearch estimates, in a single day the utility model comes into operation, and can be enterprise and has brought remarkable economic efficiency.According to measuring and calculating, the wet silver powder weight average of the every stove input of converter is 5500～6000kg, and the grade of the wet silver powder of every stove is basically identical also.If when adopting original petticoat pipe to gather dust, average every stove cigarette ash output only about 160kg, adopts the average every stove cigarette ash output of the utility model but to reach more than the 210kg.As in converter cigarette ash argentiferous average grade 20%, be equivalent to use the every stove of the utility model can reclaim more than the silver 10kg more, economic benefit is very considerable.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to structural representation.
Among the figure, the 1-cover body, the horizontal steel pipe of 2-, the vertical steel pipe of 3-, 4-petticoat pipe end opening, the 5-lateral surface, the 6-working hole, the 7-interface, the 8-steel wire rope, the 9-converter mouth, 10-rotates joint.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the movable arc petticoat pipe of silver metallurgy converter mouth of the present utility model, comprise cover body 1 and fixed support cover body anyhow to steel pipe 2,3, described petticoat pipe end opening 4 is outer low and inner high trapezoidal inclined-plane, the 13-16 that its area is generally the converter mouth area doubly; Be an acute angle a between its inclined-plane and the horizontal plane; The lateral surface 5 of petticoat pipe is processed into arc; Its arc radius R is 3800-3900mm, has on the lateral surface of described petticoat pipe for skimming, take a sample, observe the working hole 6 of usefulness.
Install and use identical with existing petticoat pipe, interface 7 with petticoat pipe one side is connected with the front end of horizontal steel pipe 2 earlier, again an end of steel wire rope 8 is fastened at horizontal steel pipe 2 front ends, the other end is fastened in the upper end of vertical steel pipe 3, and making petticoat pipe remain normal operating position above converter mouth 9 also can be in the middle rotation of rotating joint 10 freely.
Claims (4)
1. the movable arc petticoat pipe of silver metallurgy converter mouth, comprise cover body and fixed support cover body anyhow to steel pipe, it is characterized in that: described petticoat pipe bed is outer low and inner high inclined-plane, is an acute angle a between its inclined-plane and the horizontal plane; The lateral surface of petticoat pipe is processed into arc.
