Need the jet similar technological process of reducing agent of limit oxygen blast gas (or air) limit also has: the concentrate of lead sulfide ore refining is plumbous, matte refining metallic copper, ice nickel refining metallic nickel.
The utility model content
Technical problem to be solved in the utility model provides a kind of spray gun of enhancing productivity.
The technical scheme that its technical problem that solves the utility model adopts is: spray gun, comprise gas spray pipe and the gas connection that communicates with gas spray pipe, and on gas spray pipe, be connected with the powder jet pipe.
As optimal technical scheme, described powder jet pipe is arranged in the pipeline of gas spray pipe.
Further be, be outside equipped with the internal layer cooling water pipeline at gas spray pipe, the internal layer cooling water pipeline is outside equipped with outer cooling water pipeline, described internal layer cooling water pipeline communicates with the cavity of outer cooling water pipeline, be connected with the water supply connector that communicates with the cavity of internal layer cooling water pipeline on the internal layer cooling water pipeline, be connected with the water out adapter that communicates with the cavity of outer cooling water pipeline on the outer cooling water pipeline.
Further be, exit at gas spray pipe is provided with the elbow red copper rifle head with inner ring and outer ring, fixedly connected with gas spray pipe in the inner ring termination of elbow red copper rifle head, fixedly connected with outer cooling water pipeline in the termination, outer ring, have spacing between the end of internal layer cooling water pipeline and the elbow red copper rifle head, the internal layer cooling water pipeline communicates with outer cooling water pipeline by this spacing.
Further be to be fixedly connected with red copper back-fire relief pipe in the exit of powder jet pipe.
The beneficial effects of the utility model are: owing to be connected with the powder jet pipe on gas spray pipe, then when in stove, being blown into oxygen or air, can in stove, spray into the reducing agent powder by the powder jet pipe simultaneously, thereby can enhance productivity greatly, and can effectively reduce the consumption of podwer gun, simultaneously lining durability is improved, be particluarly suitable for the various occasions that need be blown into gas and reducing agent powder simultaneously and promote the use of.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
Be labeled as among the figure: gas spray pipe 1, powder jet pipe 2, gas connection 3, internal layer cooling water pipeline 4, outer cooling water pipeline 5, water supply connector 6, water out adapter 7, red copper back-fire relief pipe 8, elbow red copper rifle head 9.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1 and shown in Figure 2, spray gun of the present utility model comprises gas spray pipe 1 and the gas connection 3 that communicates with gas spray pipe 1, is connected with powder jet pipe 2 on gas spray pipe 1.Owing on gas spray pipe 1, be connected with powder jet pipe 2, then when in stove, being blown into oxygen or air, can in stove, spray into the reducing agent powder by powder jet pipe 2 simultaneously, thereby can enhance productivity greatly, and can effectively reduce the consumption of podwer gun, simultaneously lining durability is improved.
In the above-described embodiment, gas spray pipe 1 and powder jet pipe 2 can be fixedly installed together side by side, as preferred implementation, described powder jet pipe 2 is arranged in the pipeline of gas spray pipe 1, can make total more compact.
For ease of spray gun of the present utility model is cooled off, be outside equipped with internal layer cooling water pipeline 4 at gas spray pipe 1, internal layer cooling water pipeline 4 is outside equipped with outer cooling water pipeline 5, described internal layer cooling water pipeline 4 communicates with the cavity of outer cooling water pipeline 5, be connected with the water supply connector 6 that communicates with the cavity of internal layer cooling water pipeline 4 on the internal layer cooling water pipeline 4, be connected with the water out adapter 7 that communicates with the cavity of outer cooling water pipeline 5 on the outer cooling water pipeline 5.During work, cooling water enters into from water supply connector 6 in the cavity of internal layer cooling water pipeline 4 gas spray pipe 1 is cooled off, and discharges from water out adapter 7 through the cavity of outer cooling water pipeline 5 then.
For the outlet termination that prevents gas spray pipe 1 by scaling loss, as shown in Figure 2, exit at gas spray pipe 1 is provided with the elbow red copper rifle head 9 with inner ring and outer ring, fixedly connected with gas spray pipe 1 in the inner ring termination of elbow red copper rifle head 9, fixedly connected with outer cooling water pipeline 5 in the termination, outer ring, have spacing between the end of internal layer cooling water pipeline 4 and the elbow red copper rifle head 9, internal layer cooling water pipeline 4 communicates with outer cooling water pipeline 5 by this spacing.The setting of this elbow red copper rifle head 9 can prevent in the high-temp combustion process outlet termination scaling loss with gas spray pipe 1, the service life of having improved gas spray pipe 1.In addition, the spacing that between the end of internal layer cooling water pipeline 4 and elbow red copper rifle head 9, is provided with, promptly make the cavity of internal layer cooling water pipeline 4 communicate and form the circulation cavity of sealing, be beneficial to the cooling of formation gas spray pipe 1 with the cavity of outer cooling water pipeline 5.
