Abstract
The utility model discloses a swing arm type molten iron top-blowing device. The swing arm type molten iron top-blowing device is mainly composed of a motor I, a speed reducer I, a fixed plate, a swing arm, a motor II, a speed reducer II, a rotary arm I, a connecting rod, a rotary arm II and an injecting gun, wherein the speed reducer I is connected with the motor I; the fixed plate is connected with the speed reducer I; the swing arm is connected with the speed reducer I by a pin roll; the motor II is connected with the fixed plate; the speed reducer II is connected with the motor II; the rotary arm I is connected with the speed reducer II by a pin roll; the connecting rod is connected with the rotary arm I; the rotary arm II is connected between the connecting rod end and the swing arm end; and the injecting gun is connected to the swing arm. The swing arm type molten iron top-blowing device can be used for carrying out blowing desulfurization on the top of a molten iron desulfurization tank without scouring a refractory material layer on the inner wall of the molten iron desulfurization tank, so that the service cycle of the molten iron desulfurization tank is prolonged, the slag-removing efficiency is high and the iron carrying amount is small. Moreover, the swing arm type molten iron top-blowing device is simple in structure and easy to operate.
Description
Technical field
The utility model relates to a kind of molten iron top blast device, specifically belongs to a kind of swing arm molten iron top blast device.
Background technology
Hot metal pretreatment technology is removed oxious components such as sulphur, silicon and phosphorus in the molten iron, can form slag in desulfurization is handled, and therefore will skim.Traditional slag skimming process adopts slag removal machine to skim, and makes that its slag-removing time is long, efficient is low, band iron amount is big, cause iron and steel stock consumption to increase, and residue is more, and reversion easily in the converter steelmaking process is influential to steel product quality.People are in order to address the above problem, and have research to adopt desulfurizing iron jar bottom blowing process technology.Though this technology only needs at the desulfurizing iron pot bottom ventilated element to be installed, connect bottom blown gas and get final product, equipment is also simple, it is also convenient to use, and washes away seriously but the deficiency of its existence is a refractory masses to desulfurizing iron jar inwall, harm to the desulfurization tank skin is bigger, and very person's remittance causes Lou iron accident.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of and can carry out blowing desulfurization in the desulfurizing iron tank top, refractory masses degradation degree to desulfurizing iron jar inwall significantly reduces, improve the life cycle of desulfurizing iron jar, the efficient of skimming height, the little swing arm molten iron top blast device of band iron amount.
Realize the technical measures of above-mentioned purpose:
Swing arm molten iron top blast device, it is: its mainly by motor one, the step-down gear one that is connected with motor one, the retaining plate that is connected with step-down gear one, adopt swing arm, the motor two that is connected with retaining plate, the step-down gear two that is connected with motor two, the pivoted arm one that is connected with step-down gear dual-purpose bearing pin, the connecting rod that is connected with pivoted arm one that bearing pin is connected with step-down gear one, be connected in the pivoted arm two between stub end and the swing arm end, the winding-up rifle that is connected in the swing arm is formed.
It is characterized in that: the winding-up rifle is made up of steel pipe and the outer refractory masses of steel pipe.
Characteristics of the present utility model are: can carry out blowing desulfurization in the desulfurizing iron tank top, the refractory masses of desulfurizing iron jar inwall not had wash away, improve the life cycle of desulfurizing iron jar, the efficient of skimming height, band iron amount are little, and simple in structure, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-motor, one, 2-step-down gear, one, 3-retaining plate, 4-swing arm, 5-motor, two, 6-step-down gear, two, 7-pivoted arm, one, 8-connecting rod, 9-pivoted arm two, 10-winding-up rifle, 11-steel pipe, 12-refractory masses, 13-bearing pin.
Embodiment
Be described further below in conjunction with accompanying drawing:
Swing arm molten iron top blast device: motor one 1 routines are connected with step-down gear 1, step-down gear 1 is adopted bolts or is connected in retaining plate 3 by support; Step-down gear 1 adopts bearing pin 13 to connect swing arm 4; Adopt bolt or support to connect motor 25 on the top of retaining plate 3, motor 25 is adopted conventional the connection with step-down gear 26; Connecting pivoted arm 1, on pivoted arm 1, adopt stationary shaft or latch to connect connecting rod 8 with bearing pin on the step-down gear 26, between connecting rod 8 ends and swing arm 4 ends, adopt welding or latch to connect pivoted arm 29, connect winding-up rifle 10 in the end of stretching out of swing arm 4 by bolt.Winding-up rifle 10 is made up of steel pipe 11 and the steel pipe 11 outer refractory masses 12 that apply, and the gas source pipe that will have a valve is connected with the rifle 10 of jetting.
Operating principle:
When needing top blast, starter motor 1, motor one 1 drive speed reducer 1 are rotated, step-down gear 1 drives the rotation of swing arm 4 again, and swing arm 4 drives winding-up rifle 10 and rotates, and the rotation of swing arm 4 can change the upper-lower position of winding-up rifle 10, in the time of winding-up rifle 10 need being inserted the desulfurizing iron jar, swing arm 4 clockwise rotates, and it is suitable to make winding-up rifle 10 insert the degree of depth of molten iron, need to prove that the medullary ray of winding-up rifle 10 and iron ladle medullary ray are at same vertical plane; When needs adjustment winding-up rifle 10 inserts the position of desulfurizing iron jar, starter motor 25, and by 26 rotations of motor 25 drive step-down gears, the pivoted arm 1 that is connected with step-down gear 26 drives pivoted arm 29 by connecting rod 8, it is that rotate in the center of circle around the tie point of winding-up rifle 10 and pivoted arm 29 that pivoted arm 29 makes winding-up rifle 10, thereby realizes changing the purpose that winding-up rifle 10 inserts angle.
After top blast is finished, elder generation is starter motor 25 in the other direction, step-down gear 26, pivoted arm 1, connecting rod 8, pivoted arm 29, winding-up rifle 10 etc. returned to position before the top blast, starter motor 1 in the other direction again, step-down gear 1 and swing arm 4 are resetted, the rifle of jetting this moment is in holding state, and this moment, slag removal machine also can be skimmed.
When needs are changed winding-up rifle 10, pivoted arm 1 is put down, regulate swing arm 4 simultaneously and promote winding-up rifles 10 and rotate and fall the platform of skimming to the platform of skimming, at this moment, can change easily.
