Description

Gravity dust removal four-way ash removal device for blast furnace

Technical Field

The utility model relates to a gravity dust removal four-way ash removal device for a blast furnace, which belongs to the technical field of blast furnace process design in the metallurgical industry.

Background

In blast furnace production process, gravity dust collector discharges out the gravity ash through a plurality of row material branch pipes and ash discharging pipe are concentrated by the unloading chute, at gravity dust collector ash discharging in-process, because contain low melting point material such as partial alkali metal in the gravity ash, lead to the dust removal ash caking, cause the ash discharging pipe to block up, after the ash discharging pipe blockked up, just can the deashing after the flange that needs ash discharging pipe and row material branch pipe and ash discharging pipe and unloading chute disassembles, the processing difficulty is wasted time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a blast furnace gravity dust removal cross ash removal device, simple structure makes things convenient for the clearance of discharge tube, solves the problem that exists among the background art.

The technical scheme of the utility model is that:

the utility model provides a blast furnace gravity dust removal cross ash removal device, contains connecting pipe and deashing pipe, and the both ends of connecting pipe and deashing pipe all are equipped with the flange, and the diameter of deashing pipe is less than the diameter of connecting pipe, the connecting pipe contains vertical section and is connected the slope section that is a body structure with vertical section, the deashing pipe is the return bend that links into an organic whole by two straight tubes, and deashing pipe and connecting pipe link together and constitute the X type.

The turning part of the ash removing pipe is connected between the vertical section and the inclined section of the connecting pipe to form an X shape.

The central lines of two straight pipes in the ash removing pipe are respectively parallel to the central lines of the vertical section and the inclined section of the connecting pipe.

And blind plates are respectively arranged at two ends of the ash removing pipe.

Adopt the utility model discloses, during the use, with the both ends of gravity dust collector unloading pipe respectively through the connecting pipe among the device with connect row material branch pipe and unloading silo connection on the gravity dust collector, when unloading pipe blocks up, open the blind plate at deashing pipe both ends, utilize iron rod or stick to disclose out the jam part can.

The utility model has the advantages that: simple structure makes things convenient for the clearance of discharge tube, has reduced the maintenance cost, has reduced workman intensity of labour.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the present invention in use;

in the figure: 1. a gravity dust collector; 2. a discharge branch pipe of the gravity dust collector; 3. a four-way ash removal device; 4. a blind plate; 5. an upper dump valve; 6. a lower dump valve; 7. a feeding chute; 8. an ash discharge pipe; 31. a connecting pipe; 32. a dust removal pipe; 33. and (4) a flange.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to the attached drawings 1 and 2, the gravity dust removal four-way ash removal device for the blast furnace comprises a connecting pipe 31 and an ash removal pipe 32, flanges 33 are arranged at two ends of the connecting pipe 31 and the ash removal pipe 32, the diameter of the ash removal pipe 32 is smaller than that of the connecting pipe 31, the connecting pipe 31 comprises a vertical section and an inclined section which is connected with the vertical section into an integral structure, the ash removal pipe 32 is a bent pipe formed by connecting two straight pipes into an integral body, and the ash removal pipe 32 and the connecting pipe 31 are connected together to form an X shape.

In this embodiment, referring to fig. 1, the bend of the soot cleaning pipe 32 is connected between the vertical section and the inclined section of the connection pipe 31 to form an X-shape, and the center lines of two straight pipes in the soot cleaning pipe 32 are parallel to the center lines of the vertical section and the inclined section of the connection pipe 31, respectively.

Fig. 2 is a schematic diagram of the use state of the four-way ash removal device, wherein a gravity dust remover 1, two gravity dust remover discharge branch pipes 2, two ash discharge pipes 8 are arranged in the drawing, each ash discharge pipe 8 is provided with an upper ash discharge valve 5 and a lower ash discharge valve, a discharging chute 7 and four-way ash removal devices 3, blind plates 4 are arranged at two ends of each ash discharge pipe 32, and the central lines of the two ash discharge pipes 8 are parallel to the central lines of the gravity dust remover 1 and the discharging chute 7 respectively.

The gravity ash is stored in the gravity dust collector 1, when the ash needs to be discharged, the upper ash discharge valve 5 of the ash discharge pipe 8 is firstly opened, after the ash tank behind the upper ash discharge valve 5 is filled with the gravity ash, the upper ash discharge valve 5 is closed, then the lower ash discharge valve 6 is opened, and the ash discharge is realized along the discharging chute 7.

When the discharge pipe 8 is blocked, under the condition of blowing out for maintenance, the blind plate 4 of the four-way ash removal device 3 is opened, and the blocked part is poked by an iron stick or a wood stick.
