Abstract
The utility model discloses a burn iron mouth with preventing oxygen tempering oxygen therapy device, including the oxygen jar connecting pipe of one end with oxygen jar intercommunication, the other end inner gap cooperation of oxygen jar connecting pipe has sealed sleeve pipe, the intraductal interference fit of seal cover has the oxygen hose, sealed sleeve pipe stretches out outside the oxygen jar connecting pipe, oxygen jar connecting pipe clearance fit has the tip of seal cover pipe end to have the nut that the end pressure is tight that stretches out that is used for sealed sleeve pipe through thread connection. The device can effectively avoid the oxygen tempering with operating personnel hand burn, simple structure, convenient to use.
Description
Technical field
The utility model relates to the anti-oxygen tempering oxygen supply device of a kind of burning iron mouth, belongs to ironmaking technology field.
Background technology
During blast fumance, run into when iron mouth difficulty is opened and must burn iron mouth with oxygen supply device delivering oxygen.Tradition is burnt iron mouth oxygen supply device and is made up of oxygen hose, oxygen canister pipe connecting and the tightening device that connects oxygen hose and oxygen canister pipe connecting, tightening device adopts push rod to insert the push rod socket of oxygen canister pipe connecting by oxygen hose fastening, after connecting fastening, logical oxygen, blast-furnace man's operation starts to burn iron mouth.The drawback of this oxygen supply device is that sealing for tubing joints does not sternly cause waste of oxygen, simultaneously as run into oxygen pressure instability or other reasons, causes oxygen tempering, easily by operator's burn of hand.
Utility model content
The purpose of this utility model is to provide the anti-oxygen tempering oxygen supply device of a kind of burning iron mouth, and this device can effectively prevent because oxygen tempering causes operator's burn of hand, and structure is simple, easy to use.
For reaching above object, the utility model is achieved by the following technical solutions.
The anti-oxygen tempering oxygen supply device of a kind of burning iron mouth, comprise the oxygen canister pipe connecting that one end is communicated with oxygen canister, the other end inside clearance of described oxygen canister pipe connecting is combined with Sealed casing pipe, and in described Sealed casing pipe, shrink-fit has oxygen hose; Described Sealed casing pipe stretches out outside oxygen canister pipe connecting, and described oxygen canister pipe connecting running fit has the end of seal cartridge pipe end to be connected with the nut for being compressed by the external part of Sealed casing pipe by outside screw.
The feature of technique scheme and improvement further:
Further, described Sealed casing pipe is plastic seal sleeve pipe.
Further, described Sealed casing pipe is rubber seal sleeve pipe.
Further, described Sealed casing pipe profile is round table-like, and the external diameter stretching out oxygen canister pipe connecting part is greater than the external diameter inserting oxygen canister pipe connecting part.
Further, the external diameter that described Sealed casing pipe stretches out oxygen canister pipe connecting part is a bit larger tham the external diameter of oxygen canister pipe connecting.
Compared with prior art, the utility model is owing to being combined with Sealed casing pipe at oxygen canister pipe connecting one end inside clearance, in Sealed casing pipe, shrink-fit has oxygen hose, and be connected with nut in the end that oxygen canister pipe connecting arranges seal cartridge pipe end by outside screw, tightening nut, compresses Sealed casing pipe, can by oxygen hose end seals after sleeve stress, both can prevent waste of oxygen, oxygen tempering also can be avoided operator's burn of hand; Structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oxygen tempering unit when preventing from burning iron mouth of the present utility model;
In figure: 1, Sealed casing pipe; 2, oxygen hose; 3, nut; 4, oxygen canister pipe connecting.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, for one of the present utility model burns the anti-oxygen tempering oxygen supply device of iron mouth; This device comprises the oxygen canister pipe connecting 4 that one end is communicated with oxygen canister, and the other end inside clearance of oxygen canister pipe connecting 4 is combined with Sealed casing pipe 1, and in Sealed casing pipe 1, shrink-fit has oxygen hose 2; Sealed casing pipe 1 stretches out outside oxygen canister pipe connecting 4, and oxygen canister pipe connecting 4 running fit has the end of seal cartridge pipe end to be connected with the nut 3 for being compressed by the external part of Sealed casing pipe 1 by outside screw.Sealed casing pipe 1 profile is round table-like, and the external diameter stretching out oxygen canister pipe connecting 4 part is greater than the external diameter inserting oxygen canister pipe connecting 4 part; The external diameter that Sealed casing pipe 1 stretches out oxygen canister pipe connecting 4 part is a bit larger tham the external diameter of oxygen canister pipe connecting 4.
Oxygen canister pipe connecting 4 adopts iron material; Sealed casing pipe 1 adopts plastic seal sleeve pipe or rubber seal sleeve pipe, plastics and the easy stressed generation deformation of quality of rubber materials, also easily by thermogenesis deformation, and can better by oxygen hose 2 end seals.
A kind of assembling and use of burning the anti-oxygen tempering oxygen supply device of iron mouth of the utility model: nut 3 is screwed to outside oxygen canister pipe connecting 4, Sealed casing pipe 1 is inserted in oxygen canister pipe connecting 4, again oxygen hose 2 is inserted in Sealed casing pipe 1, then nut 3 is turned, Sealed casing pipe 1 is compressed by nut 3, oxygen hose 2 compresses by Sealed casing pipe 1, realize between oxygen hose 2 and oxygen canister pipe connecting 4 sealing, oxygen canister pipe connecting 4 is connected oxygen canister with oxygen canister coupling end, pass into oxygen, blast-furnace man can start to burn the operation of iron mouth.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of specification sheets, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the utility model protection.
