Abstract
The utility model discloses a granular coal delivery pipeline, which comprises a seamless steel pipe, a magnet and iron powder, wherein the magnet is arranged on the outer wall of the elbow of the seamless steel pipe; the iron powder is arranged on the inner wall of the elbow of the seamless steel pipe. When a granular coal jetting system generates compressed air while operating, the compressed air drives granular coal to move in the seamless steel pipe at a high speed. Because the magnet is arranged at the elbow of the seamless steel pipe and adsorbs the iron powder, the granular contacts with the iron powder when moving to the elbow to bear the friction instead of the pipeline, thereby protecting the ordinary seamless steel pipes, reducing the wearing and the maintenance of pipes, and prolonging the service life of the seamless steel pipes. Thus, frequent replacement of the steel pipes is avoided.
Description
Technical field
The utility model relates to pipeline conveying device, more particularly, and a kind of pipeline of conveying granular coal.
Background technique
At present, what the pipeline of blast furnace beans injection system conveying beans adopted is seamless steel pipe, as shown in Figure 1, seamless steel pipe 11 is arranged between coal bunker 12 and the blast furnace 13, during work, beans 16 injection systems produce pressurized air, beans 16 under the compressed-air actuated drive in seamless steel pipe 11 high-speed motion, produce friction with tube wall, particularly in the elbow, because beans 16 swerves in the elbow, the dynamics of beans 16 bump elbows is bigger, therefore more easy to wear in the elbow, the working life of seamless steel pipe is low, needs the frequent steel pipe of changing.
The model utility content
In view of this, the utility model provides a kind of pipeline of conveying granular coal, to improve channel bend place wear resistance, prolongs the working life of pipeline.
For achieving the above object, the utility model provides following technological scheme:
A kind of pipeline of conveying granular coal comprises:
Seamless steel pipe;
Be arranged on the magnet of the elbow outer wall of described seamless steel pipe;
Be arranged on the iron powder of the elbow inwall of described seamless steel pipe.
From technique scheme as can be seen, the pipeline of conveying granular coal among the utility model embodiment comprises: seamless steel pipe; Be arranged on the magnet of the elbow outer wall of described seamless steel pipe; Be arranged on the iron powder of the elbow inwall of described seamless steel pipe.When working, the beans injection system produces pressurized air; pressurized air drives beans high-speed motion in seamless steel pipe; owing to be provided with magnet in the elbow of seamless steel pipe; magnet absorption iron powder, therefore, when beans moves to the elbow; contact with iron powder and to act on behalf of pipeline and bear frictional force; protect common seamless steel pipe, reduced the wearing and tearing of pipeline and the maintenance load of pipeline, prolonged the working life of seamless steel pipe.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a seamless steel pipe scheme of installation in the prior art;
The piping erection schematic representation of the conveying granular coal that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of pipeline of conveying granular coal, to improve channel bend place wear resistance, prolongs the working life of pipeline.
Please refer to Fig. 2, wherein, 21 is seamless steel pipe; 22 is coal bunker; 23 is blast furnace; 24 is magnet; 25 is iron powder; 26 is beans.
The pipeline of this conveying granular coal comprises: seamless steel pipe 21, magnet 24 and iron powder 25, and wherein, seamless steel pipe 21 is arranged between coal bunker 22 and the blast furnace 23; Magnet 24 is arranged on the elbow outer wall of seamless steel pipe 21; Iron powder 25 ends are arranged on the elbow inwall of seamless steel pipe 21.
When working, beans 26 injection systems produce pressurized air; pressurized air drives beans 26 high-speed motion in seamless steel pipe 21; since be provided with magnet 24 in the elbow of seamless steel pipe 21, magnet 24 absorption iron powder 25, therefore; when beans 26 moves to the elbow; contact with iron powder 25 and to act on behalf of pipeline and bear frictional force, protect common seamless steel pipe 21, reduced the wearing and tearing of pipeline and the maintenance load of pipeline; prolong the working life of pipeline, need not frequently to change steel pipe.
In addition, in use, also sneak into iron powder in coal bunker 22, when beans and iron powder moved to the elbow of seamless steel pipe 21, iron powder 25 was attracted by magnet 24, was adsorbed on the inner-walls of duct frictional force that replaces pipeline to bear material.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
