One or more embodiments of this application provide a novel dust collector for electric stove balling, can solve the electric stove balling in-process smoke and dust and emit the condition, improve workshop environment.
The technical solution of one or more embodiments of the present application will be described in detail below by specific examples, and a novel dust removing device for spheroidizing an electric furnace, as shown in fig. 1, includes:
the dust hood 1 is provided with a gap 14 for the hook 5 to pass through and is used for shielding smoke dust generated in the spheroidizing process of the electric furnace;
the dust removal pipeline 2 comprises an air suction opening 21 positioned at the inner top of the dust removal cover 1, is connected with an air suction mechanism, and is configured to absorb smoke dust in the dust removal cover 1 and suck the smoke dust shielded by the dust removal cover 1 through the air suction opening 21;
Specifically, lifting hook 5 passes ladle 4 is connected to breach 14, and the electric stove balling is in go on in the dust excluding hood 1, open earlier before the electric stove balling the air supply mechanism of tuber pipe 3, the wind that air supply mechanism sent is highly-compressed air, and wind is a plurality of blowout forms the high-pressure air curtain in the slit 31, carries out electric stove balling work again, opens dust removal pipeline 2's the mechanism that induced drafts, inlet scoop 21 can siphon away the smoke and dust that the electric stove balling produced in the dust excluding hood 1 correspondingly, carries out the smoke and dust that balling process kicked up at the molten iron and arrives during high-pressure air curtain department, quilt the high-pressure air curtain blocks and is in breach 14 lower part, quilt promptly afterwards dust removal pipeline 2 siphons away, has solved the smoke and dust and has passed through breach 14 runs out, pollutes the problem of workshop environment.
In some embodiments, as shown in fig. 1, the dust removing cover 1 includes a connecting cover body 11, a first cover body 12 and a second cover body 13, the first cover body 12 and the second cover body 13 are symmetrically arranged with respect to the air suction opening 21, one end of the first cover body 12 is fixedly connected with one end of the corresponding second cover body 13 through the connecting cover body 11 to form an accommodating space, the other end of the first cover body 12 and the other end of the corresponding second cover body 13 form the notch 14 for communicating the accommodating space with the outside, the connecting cover body 11 is arranged to block smoke generated by spheroidizing of an electric furnace in the dust removing cover 1 and also provide an installation space for the dust removing pipeline 2, and according to the principle that smoke floats on smoke, the dust removing pipeline 2 can suck the smoke more comprehensively, and the dust removing effect is better.
In some embodiments, as shown in fig. 1, two air ducts 3 are provided, and are respectively and fixedly connected to the top of the outer side of the first cover body 12 and the top of the outer side of the second cover body 13, and the thin seams 31 on the two air ducts 3 face each other to form a high-pressure air curtain, which can make up for the deficiency that the terminal pressure of the high-pressure air curtain is reduced and the effect of shielding smoke is weakened, so that the effect of shielding smoke generated by spheroidizing of the electric furnace by the high-pressure air curtain is stronger.
In some embodiments, as shown in fig. 2, the plurality of slits 31 respectively disposed in the two air ducts 3 are arranged in a staggered manner, the position of the slit 31 disposed on each air duct 3 matches with the notch 14, and there is a gap between the slits 31, so that in the use process, a gap is generated in the formed high-pressure air curtain, so that part of the smoke dust flows out from the gap, which pollutes the workshop environment, and the plurality of slits 31 arranged in the two air ducts 3 in a staggered manner can mutually compensate the gap on the high-pressure air curtain, so that the effect of the high-pressure air curtain for shielding the smoke dust is better.
In some embodiments, as shown in fig. 3, the slit 31 is inclined toward the inside of the dust hood 1, a high-pressure air curtain formed by the slit 31 has an angle with the notch 14, and the high-pressure air curtain can blow the smoke into the dust hood 1 while blocking the smoke, so as to block the smoke from drifting out, and thus, blocking the smoke is facilitated.
In some embodiments, as shown in fig. 3, an included angle between the orientation of the slit 31 and the horizontal direction of the cross section of the air duct 3 is 5 °, the horizontal axis of the air duct 3 is a, the axis of the slit 31 and the center of the air duct 3 is b, the included angle is α, and if the included angle is too large, the formed high-pressure air curtain cannot play a role of blocking the smoke, so that the included angle α is 5 ° more appropriate, which not only can achieve an effect of blocking the smoke, but also can blow the smoke into the dust removal cover 1, so that the effect of blocking the smoke from flowing out of the gap 14 by the air duct 3 is stronger.
In some embodiments, the inner diameter of the air pipe 3 is 30 to 40mm, the air pipe 3 can transmit the air sent by the air supply mechanism to a plurality of slits 31, the air pipe 3 plays a role of transmitting air, and consumes a part of the air pressure sent by the air supply mechanism, so the inner diameter of the air pipe 3 is better when the air pressure sent by the air supply mechanism is 30 to 40mm, the inner diameter of the air pipe 3 is too large to consume too much air pressure sent by the air supply mechanism, so that the operation efficiency of the air supply mechanism is reduced, and the inner diameter of the air pipe 3 is too small to cause the occupied proportion of the slits 31 to be too high, so that the phenomenon of air leakage occurs, and the formation of the high-pressure air curtain is not facilitated.
In some embodiments, as shown in fig. 1, the distance between the two air pipes 3 is 400 to 500mm, and the distance between the two air pipes 3 is the width of the high-pressure air curtain, considering that the shielding effect of the end point of the high-pressure air curtain is weakened, and the distance for forming the high-pressure air curtain is limited, therefore, the distance between the two air pipes 3 is preferably 400 to 500mm, which can not only meet the requirement of the hook 5, but also make the high-pressure air curtain shield smoke dust best.
In some embodiments, as shown in fig. 1, the air suction opening 21 is inclined downward, the plane of the air suction opening 21 is a tangent plane forming a certain included angle with the axis of the dust removal pipeline 2, the area of the tangent plane is larger than the area of the cross section perpendicular to the axis of the dust removal pipeline 2, and the amount of dust sucked by the air suction opening 21 under the same condition is more, so that the dust removal effect of the dust removal pipeline 2 is better.
In some embodiments, as shown in fig. 1, the top of the first cover 12 and the top of the second cover 13 are in a trapezoidal plate structure, and according to the principle that smoke floats upwards, the top of the first cover 12 and the top of the second cover 13 adopt a trapezoidal plate structure to shield smoke from the top of a side and the top of a front, and a space is left at the bottom of a side for observation in the furnace spheroidizing process, without affecting the dust removing effect of the dust removing device.
Those of ordinary skill in the art will understand that: the discussion of any embodiment above is meant to be exemplary only, and is not intended to intimate that the scope of the disclosure, including the claims, is limited to these examples; within the idea of the invention, also technical features in the above embodiments or in different embodiments can be combined, steps can be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity.
