Description

A kind of device of Quick dredging magnesium-alloy smelting furnace pipeline

Technical field

It the utility model is related to pipe dredging device, more particularly to a kind of device of Quick dredging magnesium-alloy smelting furnace pipeline.

Background technology

As 3C electronic products constantly pursue lightening, particularly mobile phone productses, some new materials and new skill are continued to bring out Art application, plate is favored by market extensively because mechanical performance is prominent and lighter weight in magnesium alloy.But magnesium alloy Can be active, particularly under high-temperature liquid state state, burning just occurs with air contact or even explodes.So in actual production, must Itself and air exclusion must be made, protected using inertia；Generally magnesium liquid is injected into shot sleeve by automatic ration batcher, its Middle magnesium liquid need to pass through in the gooseneck and nozzle and then arrival sleeve pipe of closing.But magnesium-alloy smelting furnace gooseneck position easily by magnesium slag, Magnesium material after the oxide of magnesium and cooling is blocked, and the melting such as magnesium alloy oxide for needing to block at gooseneck before every subjob is dredged , could normal production operation after logical.

Industrial at present, generally use dissolving with hydrochloric acid cleaning magnesium-alloy smelting furnace pipeline is mainly easy using magnesium alloy and strong acid The mode to chemically react is dredged to pipeline.The strong acid has the feature such as severe corrosive and penetrating odor, to environment And personnel health has a great influence, operating process need to wear tight safety device, relatively complicated, while strong acid also has to tube wall Corrosivity, the corrosion and ageing of long-term use of easily acceleration equipment, or even trigger blast；On the other hand the dredging time is longer, to production Have a great influence.

In summary, existing magnesium-alloy smelting furnace pipe dredging device, in practice in the presence of it is inconvenient the problem of, it is therefore necessary to Improved.

A kind of device of Quick dredging magnesium-alloy smelting furnace pipeline, including fuel cartridge, Gas Pipe, gun shot, dredging bar；It is described Gun shot is connected with fuel cartridge by Gas Pipe；The gun shot is connected by fixture with dredging bar cluster.

It is preferred that the dredging bar includes sleeve pipe and solid hopkinson bar；The solid hopkinson bar is through sleeve pipe and front and rear can move freely； The solid hopkinson bar front end is arranged to cone, and rear end is arranged to kink.

It is preferred that the fixture includes two 8 word snap rings, the one 8 word snap ring close to dredging bar front end, close to dredging 2nd 8 word snap ring of rod rear end；The one 8 word snap ring sets screw screens close to solid hopkinson bar front end side.

It is preferred that the gun shot is high temperature resistant stainless steel material, front end is arranged to trumpet type, and control is set close to rear end Valve processed.

It is preferred that the gun shot is connected with Gas Pipe by connector.

It is preferred that the Gas Pipe is quality of rubber materials.

Using such scheme, the beneficial effects of the utility model are：

1) pipe-dredging efficiency is significantly improved, below 0.5H is reduced to by original 2H or so；

2) effectively strong acid operation is evaded, it is simple to operate, hence it is evident that to reduce human users' risk；

3) the aging corrosion risk of tube wall is reduced, extends Gas Pipe service life；

4) overall structure is simple, carries simplicity, safe.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

As shown in figure 1, a kind of device of Quick dredging magnesium-alloy smelting furnace pipeline, including fuel cartridge 1, Gas Pipe 2, gun shot 3rd, bar 4 is dredged；The gun shot 3 is connected with fuel cartridge 1 by Gas Pipe 2；The gun shot 3 passes through fixture 5 and dredging bar 4 Cluster connects.

Wherein, the dredging bar 4 includes sleeve pipe 41 and solid hopkinson bar 42；The solid hopkinson bar 42 through sleeve pipe 41 and can it is front and rear oneself By moving；The front end of solid hopkinson bar 42 is arranged to cone 421, and rear end is arranged to kink 422.The fixture 5 includes two Individual 8 word snap ring 51,52, the one 8 word snap ring 51 close to dredging bar 4 front end, the 2nd 8 word snap ring 52 close to dredging bar 4 rear end； The one 8 word snap ring 51 sets the screens of screw 6 close to the front end side of solid hopkinson bar 42.The gun shot 3 is high temperature resistant stainless steel Material, front end are arranged to trumpet type 31, and control valve 32 is set close to rear end.The gun shot 3 passes through connector with Gas Pipe 2 7 connections.The Gas Pipe 2 is quality of rubber materials.

In the present embodiment, fuel cartridge 1 is portable storage tank, can store 2kg or so compressed petroleum gas/coal gas, overall weight 5kg or so, relatively safe band can be arbitrarily positioned in practical operation, load is smaller, easy to operate.Rubber Gas Pipe 2 is anti-height Warm, ageing-resistant extended type pipeline, duct length 2m, facilitate practical operation, and gun shot 3 can be remote in practical operation From fuel cartridge 1, ensure processing safety.The gun shot 3 is the special gun shot 3 of extended type, and the gun shot 3 is up to 400mm, is High temperature resistant stainless steel material, there is higher-strength, nonabradable feature；The front end of gun shot 3 is arranged to trumpet type 31, to expand Big flame burning area；One control valve 32 is set on gun shot 3, so as to arbitrarily control the flame size of gun shot 3.Dredge bar 4 For special tool, including sleeve pipe 41 and solid hopkinson bar 42；The front end of solid hopkinson bar 42 sets the screens of screw 6, can effectively prevent solid hopkinson bar 42 Depart from sleeve pipe 41；The rear end of solid hopkinson bar 42 is kink 422, facilitates practical operation, while prevents solid hopkinson bar 42 from departing from sleeve pipe 41；It is real The front end of core bar 42 for cone 421, and with mobile jib arc transition, facilitate actual dredge blockage thing.Dredge bar 4 and the shape of gun shot 3 Integrally, the flame of gun shot 3 is while heating, melting tamper in actual job, and dredging bar 4 is while extruding dredging, the above two Person combines, and effectively can remove tamper, so as to reach the purpose of Quick dredging pipeline.

By above dredger, actual dredging efficiency can be significantly improved, reduces the dredging time, so as to improve production effect Rate, reduce cost；Device humanization designing, it can effectively evade strong acid operation, simple to operate, operating personnel need to only wear high temperature resistant Gloves, without other special protection, human users' risk is can obviously reduce, it is safe.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
