If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1, the furnace mouth feeding sealing device comprises a lower powder cone 15, a sealing cover 11 installed at an inlet of a combustion furnace 20, and a conveying steel belt 10 penetrating through the sealing cover 11 and the combustion furnace 20, wherein a feeding end of the lower powder cone 15 penetrates through the sealing cover 11 and then is positioned above the conveying steel belt 10, the feeding end of the lower powder cone 15 divides the inside of the sealing cover 11 into a first space 19 close to the combustion furnace 20 and a second space 13 far away from the combustion furnace 20, and a first nitrogen pipe 12 communicated with the second space 13 is arranged on the sealing cover 11. The first nitrogen pipe 12 is externally connected with a nitrogen source. The blanking end of the lower powder cone 15 is provided with a control valve 14 for controlling the opening and closing of the blanking end, and the control valve 14 is positioned outside the sealing cover 11. The sealing cover 11 covers the feed opening of the lower powder cone 15 and the front end of the conveying steel belt 10 together, and a first nitrogen pipe 12 is additionally arranged at the front end of the lower powder opening to prevent air at an inlet from entering the feed opening. The direction indicated by the arrow in fig. 1 is the direction in which the powder is transported by the steel belt 10.
The sealing cover 11 is provided with a second air pipe 18 communicating with the first space 19. A second nitrogen pipe 18 is arranged in front of the inlet of the combustion furnace 20, and the second nitrogen pipe 18 is externally connected with a nitrogen source. During production, nitrogen enters the first space 19 along the second nitrogen pipe 18, so that the powder is completely protected by the nitrogen before entering the furnace body of the combustion furnace 20.
The second air pipe 18 is communicated with the discharging end of the powder discharging cone 15 through a branch pipe 17. The control valve 14 divides the discharge end into a first end close to the discharge opening and a second end above the first end, and the junction of the branch pipe 17 and the discharge end is located at the second end, i.e. the junction of the branch pipe 17 and the discharge end is located above the control valve 14. The nitrogen enters the lower powder cone 15 through the second nitrogen pipe 18 and the branch pipe, and the nitrogen exhausts the air from the lower powder cone 15, so that the probability of the air entering the sealing cover is reduced.
And the sealing cover 11 is provided with an observation and maintenance window 21 for observing the feed opening of the lower powder cone 15. The 21 port of the observation and maintenance window is sealed by toughened glass and silica gel, and is tightened by screws during normal production to prevent air from entering.
The upper end face of the lower powder cone 15 is provided with a spring top plate 16, and the outer ring of the spring top plate 16 is provided with a circle of silica gel skin. When the material frame is placed downwards, the material frame is attached to the spring top plate 16, and the phenomenon that air is brought into a discharging cone by powder is reduced.
As shown in FIG. 1, the sealing cover is provided with two straight portions and a convex portion, the convex portion is located between the two straight portions, the blanking end of the blanking cone passes through the convex portion and then is located in the sealing cover, the first nitrogen pipe 12 passes through the outer wall of one of the straight portions and then is communicated with the second space 13, and the second nitrogen pipe 18 passes through the outer wall of the remaining one of the straight portions and then is communicated with the first space 19. The observation and maintenance window 21 is provided on the front side of the boss.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
