Abstract

The invention relates to a slagging door for metallurgic furnaces, wherein a slagging door opening is provided in the upper receptacle of the furnace with a door tunnel having a sill plate and the slagging door can be actuated by a closure mechanism. The closure mechanism is disposed outside the furnace wall and in front thereof, and the clear cross section of the slagging door opening can be closed by means of at least two horizontally pivotable door leaves.

Description

The ash gate that is used for metallurgical furnace

Technical field

The present invention relates to a kind of ash gate for metallurgical furnace, during one of them deslagging door opening is arranged on and loads, have the gateway of a tape base platen, and can grasp from ash gate by a closing organ.

Background technology

By WO 2007/147248 known a kind of ash gate that constitutes three-member type.

Constitute around renovating of can swinging of a horizontal axis by one at door part or the door leaf on this top, and thereunder arrange two around vertical axis door leaf that can swing, finger-like.

For the swing mechanism of renovating and for the adjustment of bottom door leaf or the furnace wall that closing organ all is arranged on burner hearth.

Summary of the invention

Task of the present invention is to provide a kind of ash gate, it structurally not really expensive and special the permission in existing metallurgical furnace, install afterwards, and need not very large modification measures.

According to the present invention, solve this task by a kind of ash gate for metallurgical furnace, during one of them deslagging door opening is arranged on and loads, have one with the gateway of a base station plate, and can handle ash gate by a closing organ.

Be used herein to and prevent that the closing organ that waste material falls into is arranged on outside the furnace wall, before the furnace wall,

Can close the clean cross section of deslagging door opening by the door leaf that at least two levels can be swung, wherein

Door leaf can be positioned on three positions at least,

A primary importance is wherein arranged, and in this primary importance, door leaf is in the plane basically,

A second place, this second place perpendicular to common plane and be open position and

The 3rd position, in the 3rd position, door leaf points to ground towards the furnace interior direction and forms an acute angle, opens the slit thereby open one between door leaf.

Preferred form of implementation is provided by each dependent claims and is that four door leafs are set, and these door leafs overlap up and down in couples, and these door leafs can be handled independently of each other.

Preferably, door leaf can be positioned on the position, and in this position, door leaf is outwards opened with acute angle, thereby can realize a kind of controlled deslagging by the slit that forms between door leaf edge.

Description of drawings

Below with reference to the accompanying drawings the present invention is explained in detail.Wherein:

The schematic diagram of Fig. 1 ash gate structure exactly has the schematic diagram of ash gate in diverse location of two door leafs,

The view of the another kind structure of two door leafs of Fig. 2, and

Fig. 3 has the view of a kind of form of implementation of four door leafs.

The specific embodiment

In these schematic diagrames, only sketch the contours of the furnace wall of metallurgical furnace and represent with Reference numeral 1.

A door opening 2 is set in this furnace wall.Before this door opening 2, before the wall that is formed by the furnace wall, a framework 3 is shown symbolically before this wall just more precisely, door leaf 4,5 and 6～9 all is fixed on this framework, and perhaps they are kept by framework.

A closing organ that is used for corresponding door leaf is connected with framework 3, and this closing organ is not shown here.

Illustrated in the accompanying drawings is each schematic diagram of the door leaf position that may have,

In Fig. 1 or 2, exactly be to be closed condition shown in the schematic diagram on top.

According to the necessity near furnace interior, can open one of them or two door leafs.

In a kind of special circumstances shown in the schematic diagram of the bottom of Fig. 1 or 2, exactly, door leaf has an acute angle that points to towards the furnace interior direction here, and this causes staying next slit between opposed door leaf edge.

This mobility of door leaf can realize the cleaning of base station plate by passing slag backward.

Also has a door leaf position with the acute angle of outside unlatching that does not illustrate in the drawings at last.

With the same in the position of inwardly pointing to, at this moment between opposed door leaf edge, also open a slit, a kind of in check deslagging can be realized in this slit.

Obviously, the position of door leaf also can be positioned on any other position, but mainly is above-described position.

If for example different positions can individually be adjusted and can be positioned on to door leaf, the possibility that then obtains is to control bed drain purge outside from stove and/or the slag height in stove.

The last diverse location that door leaf is shown equally shown in Figure 3 has four door leafs that arrange in pairs in this case.

The door leaf of bottom can be used for the cleaning of slag control and base station plate at open position, and the door leaf on top then can be realized further for example can carrying out maintenance work near furnace interior at its open position.

Claims

1. be used for the ash gate of metallurgical furnace, wherein, a deslagging door opening is arranged in the loading of stove, has one with the gateway of a base station plate, and handles ash gate by a closing organ,

It is characterized in that,

-closing organ is arranged on outside the furnace wall, before the furnace wall,

-the door leaf that can swing by at least two levels can cut out the clean cross section of deslagging door opening, wherein

-door leaf can be positioned on three positions at least,

2. ash gate according to claim 1 is characterized in that, four door leafs are set, and these door leafs overlap up and down in couples.

3. ash gate according to claim 1 is characterized in that, door leaf can be handled independently of each other.

4. ash gate according to claim 3 is characterized in that, door leaf can individually be adjusted and can be positioned on the different positions, thereby can control bed drain purge outside from stove and/or the slag height in stove.
