Abstract

The utility model discloses an air supply device of the barrel converter. The utility model is characterized in that the device comprises a U-shaped blast pipe, a vertical blast box, a horizontal blast box and a horizontal blast pipe device, wherein, the U-shaped blast pipe is a blast supply pipe of a horizontal equipment; the vertical blast box adopts the structure of a plurality of vertical type cabinets with openings at both the upper end and the lower end, the upper end opening is communicated and connected with the U-shaped blast pipe; the horizontal blast box is a long horizontal type neck-through-body blast box with a right angle shaped cross section, and an opening arranged on the upper surface of the horizontal blast box is connected fixedly with the lower end opening of the vertical blast box; penetrating horizontal through holes which are vertical to the lateral surface of the box body are arranged at the right angle shaped part at the bottom part; the level of the horizontal blast pipe end of the horizontal blast pipe device is penetrated through the through hole, and the end head is positioned in the horizontal converter. When the high pressure blast is distributed uniformly in the vertical blast box and horizontal blast box, the pressure of the high pressure blast which gets to all blast pipes of the converter is balanced, the wind supply pressure is stable, and the maintenance is convenient.

Description

The pierce smith converter air supply device

Technical field

The utility model relates to a kind of air supply device of pierce smith converter of metallurgical process.

Background technology

The used air supply device of tradition metallurgical converter is by compositions such as the bellows on the cylindrical shell, the U-shaped airduct, each air arm that is connected with the U-shaped airduct and the eye of wind device that connect bellows, horizontal airducts.This air supply device makes between each air arm and exists pressure of air supply inconsistent, causes each air duct blow inhomogeneous; The unreasonable structure of the eye of wind, life-time service cause the eye of wind device race wind that deforms easily, are unfavorable for that machinery discloses eye of wind operation; Repair and maintenance difficulty, eye of wind device deform needs overall pulling down, and labour intensity is big.

Summary of the invention

The purpose of this utility model is exactly the deficiency that the above-mentioned prior art of specific aim exists, and a kind of air feed pressure-stabilisation, eye of wind turnaround of unit pierce smith converter air supply device easy to maintenance are provided.

The purpose of this utility model is achieved through the following technical solutions.

The pierce smith converter air supply device is characterized in that the structure that its device comprises has:

U type airduct-this U type airduct is the air feed pipe of horizontal plants;

Case was that some two ends up and down are the vertical cabinet structure of opening in vertical bellows-this was vertical, and its upper end open connects with U type airduct UNICOM;

Horizontal bellows-this horizontal bellows is that section is that the right angle " turns " the long bellows of entire body shape, horizontal, and it is affixed with vertical bellows lower ending opening that horizontal bellows top box face has port; " turn " shape portion in the bottom and run through the horizontal through hole that runs through that has with the arrangement of casing lateral vertical;

The level of the horizontal airduct end of horizontal airduct device-this device is passed the through hole of horizontal bellows, and the termination is positioned at pierce smith converter.

Pierce smith converter air supply device of the present utility model, its U-shaped airduct is introduced horizontal bellows with wind by several vertical bellows, by horizontal bellows uniform and stable wind is sent into each the horizontal airduct that is attached thereto; The number of the through hole on the horizontal bellows and the number of horizontal airduct and eye of wind device is suitable.

Device of the present utility model, because high-pressure blast infeeds horizontal bellows again after several vertical bellows uniformly distributings, wind in horizontal bellows once more by uniformly distributing, uniformly distributing through twice, pressure was isostatic when high-pressure blast arrived the horizontal airduct of each that send into converter, and air feed pressure-stabilisation, repair and maintenance are convenient.

Fig. 2 is a section section of the present utility model.

Embodiment

The purpose of this utility model is achieved through the following technical solutions.

The pierce smith converter air supply device, the structure that its device comprises has: the air feed pipe that this U type airduct of U type airduct 1-is a horizontal plants; Vertical bellows 2-should vertical interior case be that some two ends up and down are the vertical cabinet structure of opening, and its upper end open connects with U type airduct UNICOM; This horizontal bellows of horizontal bellows 3-is that section is that the right angle " turns " the long bellows of entire body shape, horizontal, and it is affixed with vertical bellows lower ending opening that horizontal bellows top box face has port; " turn " shape portion in the bottom and run through the horizontal through hole that runs through that has with the arrangement of casing lateral vertical; The level of the horizontal airduct end of horizontal this device of airduct device 4-is passed the through hole of horizontal bellows, and the termination is positioned at pierce smith converter 5.

Vertical bellows of the present utility model can adopt 4 uniform vertical bellows to be connected with U-shaped airduct, horizontal bellows up and down.Can also adopt 6 or 8.Certain vertical bellows should be not too many, increases workload otherwise can give change horizontal bellows, if can be even, stable give horizontal bellows air feed.When high-pressure blast infeeds horizontal bellows again after several vertical bellows uniformly distributings, wind in horizontal bellows once more by uniformly distributing, through twice uniformly distributing, pressure was isostatic when high-pressure blast arrived the horizontal airduct of each that send into converter, and air feed pressure-stabilisation, repair and maintenance are convenient.
