Background
The consumption of the ladle nozzle drainage sand of the converter in the steel plant is always high. Through on-site tracking observation, the drainage sand adding device is unreasonable, and in the process of adding sand into a steel ladle, the lower opening of the sand adding device cannot be lowered into the water gap of the steel ladle, otherwise, the lower opening of a pipe is easily blocked, so that sand adding is not full, and potential production hazards are caused. But not drop inside the mouth of a river, the sanding pipe is in the unsettled state, rocks easily, can not aim at the ladle mouth of a river completely during the sanding, causes that partial drainage sand does not add inside the mouth of a river, forms the material extravagant.
Disclosure of Invention
The utility model discloses to prior art's not enough, provide a converter ladle drainage sand sanding device, form the tripod with three spinal branch vaulting poles of drainage sand sanding pipe end opening welding, through the hoist system during sanding, descend the sanding pipe to ladle mouth of a river position, the tripod supports in the ladle mouth of a river, form fixedly with the help of the dead weight of sanding pipe, make the sanding pipe no longer unsettled, sanding process pipe can not rock, in drainage sand trickles the ladle mouth of a river from the pipeline end opening, avoid adding the mouth of a river outside, it is extravagant to eliminate.
In order to achieve the above object, the utility model provides a following technical scheme: converter ladle drainage sand adds sand device includes:
adding a sand pipe;
the inner diameter of the circular ring is not less than the outer diameter of the sand adding pipe and is greater than the minimum diameter of the inverted circular truncated cone section of the converter ladle nozzle, and the outer diameter of the circular ring is less than the maximum diameter of the inverted circular truncated cone section of the converter ladle nozzle;
the bracing piece, the bracing piece has three at least, the bracing piece is including the canned paragraph that sets gradually from top to bottom, the down tube section, the bending segment, canned paragraph fixed mounting is on the outer wall of sanding pipe, down tube section and ring fixed connection, the axis of down tube section is from top to bottom slant peripheral hardware in the axial of sanding pipe, the bending segment is from the lower extreme of down tube section from top to bottom slant peripheral hardware in the axial of down tube section, the axis of bending segment is unanimous with the contained angle of radius bench section and horizontal plane.
In addition to the above, preferably, the ring is fixed to the lower end of the diagonal member segment.
On the basis of the scheme, preferably, the number of the support rods is three, and the support rods are uniformly distributed in the circumferential direction of the sand adding pipe.
On the basis of the scheme, the supporting rod and the sand adding pipe are preferably welded and fixed.
On the basis of the above scheme, as preferred, still include the stiffener, stiffener one end fixed connection is on the bending segment, and other end fixed connection is on the down tube section.
Compared with the prior art, the beneficial effects of the utility model are that:
the three support rods for welding the lower opening of the drainage sand adding pipe form a tripod, the sand adding pipe is descended to the position of a water port of a steel ladle through a hoisting system during sand adding, the tripod-shaped support is supported in the water port of the steel ladle, the sand adding pipe is fixed by means of self weight of the sand adding pipe, the sand adding pipe is not suspended any more, the sand adding pipe cannot shake, and drainage sand flows to the water port of the steel ladle from the upper opening of the pipeline, so that the waste is avoided being added to the outer side of the water port.
The included angle between the axis of the bending section and the horizontal plane is consistent with the included angle between the inverted circular truncated cone section and the horizontal plane, and the stability is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of a converter ladle nozzle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention, and in the present application, detachable means a connection mode that can separate the part from another part without changing the original structure of the part.
The converter ladle nozzle comprises an inverted circular truncated cone section 6 and a straight rod section 7.
As shown in fig. 1-2, the ladle filler sand adding device of the converter comprises:
a sand adding pipe 1;
the inner diameter of the ring 5 is not less than the outer diameter of the sand feeding pipe and is greater than the minimum diameter of the inverted circular truncated cone section 6 of the converter ladle nozzle, and the outer diameter of the ring is less than the maximum diameter of the inverted circular truncated cone section of the converter ladle nozzle;
the bracing piece, the bracing piece has three at least, the bracing piece is including the canned paragraph 2 that from top to bottom sets gradually, down tube section 3, bending segment 4, canned paragraph fixed mounting is on the outer wall of sanding pipe, down tube section and ring fixed connection, the axis of down tube section is set up from top to bottom slant outward in the axial of sanding pipe, bending segment is from the lower extreme of down tube section setting up from top to bottom slant outward in the axial of down tube section, bending segment's axis is unanimous with the contained angle of radius bench section and horizontal plane with the contained angle of horizontal plane, also the slope is unanimous, bending segment's lower edge can be the plane, improve the stability of contact.
In the scheme, the design of the supporting rod is added at the bottom of the funnel sand adding pipe, so that the lower end of the sand adding pipe is fixed and not suspended when contacting the bottom (water gap) of the ladle, and meanwhile, the sand adding pipe is not inserted into the water gap.
