CN206143234U - Blast furnace air supply system processing apparatus that leaks out - Google Patents

Abstract

The utility model discloses a blast furnace air supply system processing apparatus that leaks out, including a latericumbent U type body, the one end of body sets up screw hole, a jack panel screw in in the screw hole, push up the top of jack panel and stretch into the expansion joint tip butt in the U type body, the below of expansion joint tip is in proper order for sealing white steel layer and air supply system terminal surface. The utility model discloses an advantage: this equipment passes through fastening bolt, and wind position face is run in the extrusion to the faying face of tight real air supply system and expansion joint reaches sealed effect.

Description

A kind of blast furnace air supply system leaks out processing meanss

Technical field

This utility model is related to steelmaking technical field, and specifically one kind is leaked out processing meanss.

Background technology

During blast furnace staying, supply air system natural cooling easily produces gap with expansion joint junction, and the portion is caused after air-supply Position is serious to run wind, and hot blast is easily burnt in a high voltage state on-site personnel, causes security incident, is such as dealt with improperly, will also Cause supply air system to crumple or melting loss, cause secondary damping down.At present wind is run to solve air-supply initial stage air port, can only be before air-supply Strengthen checking, after air-supply wind is run, it is difficult to which band wind is processed and runs wind position, affects furnace condition recovery process.

The content of the invention

The invention provides a kind of can efficient under blast furnace ventilation state, reliable, safely fasten supply air system gap Tuyere equipment." U " the type body and supporting bolt two parts that the equipment is drilled by side is constituted.Body is side inverted U buckle, Side drills, and is processed into screw thread, and the bolt that making matches is engaged therewith.Buckle side is buckled in into air leakage parts air-supply when using At system and expansion joint connecting end surface, can will be leaked out by clamp nut and locate gap slowly consolidation, it is ensured that normal safe is blown, and is kept away Exempt from therefore to cause the production accident of second repetition damping down.Concrete technical scheme is as follows：

A kind of blast furnace air supply system leaks out processing meanss, including a U-shaped body lain on one's side, and one end of the body arranges spiral shell Pit, one holds out against nut screws in the screwed hole；The top for holding out against nut and the expansion joint end stretched in U-shaped body Abut；The white steel layer of sealing and supply air system end face are followed successively by below the expansion joint end.

Advantage of the present utility model:By fastening bolt, wind position plate face is run in extruding to this equipment, so as to consolidation supply air system With the faying face of expansion joint, the effect of sealing is reached.

Description of the drawings

Fig. 1 is the structural representation of the present invention.

Specific embodiment

This utility model is illustrated below in conjunction with the accompanying drawings, as shown in figure 1, this utility model includes U-shaped for lying on one's side Body 1, one end of the body 1 is threaded hole, and one holds out against nut 2 screws in the screwed hole；The top for holding out against nut 2 Abut with the expansion joint end 3 stretched in U-shaped body；The lower section of the expansion joint end 3 is followed successively by the white steel layer 5 of sealing and air-supply System end face 4.

Key point of the present utility model

(1) " U " type body openings width is 80mm～200mm, can be according to the spirit of the supply air system end surface thickness of different manufacturers Design living, the diameter of bolt >=60mm.

(2) " U " type body material is cast steel.

Claims (1)

1. a kind of blast furnace air supply system leaks out processing meanss, it is characterised in that：Including a U-shaped body lain on one's side, the body One end is threaded hole, and one holds out against nut screws in the screwed hole；The top for holding out against nut with stretch in U-shaped body Expansion joint end abutment；The white steel layer of sealing and supply air system end face are followed successively by below the expansion joint end.
