Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1, magnesium powder tank; 2, brace and connecting rod framework; 3, air inlet I; 4, conduit; 5, crank; 6, connecting rod; 7, guide rod; 8, fairlead; 9, oil filler point; 10, stopper head; 11, air inlet II; 12, Inserting Tube; 13, stop valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of automatic powder feeding device for pressure desulfurization, this device comprises magnesium powder tank 1, brace and connecting rod framework 2 and the reductor for driving crank bar linkage structure 2, the reductor in this device adopts the plug-in frequency converter of reductor. The below of magnesium powder tank 1 is provided with a conduit 4 for delivery of magnesium powder, and conduit 4 is made up of thick-walled seamless steel pipes, and inwall adopts roll extrusion processing. The top of magnesium powder tank 1 has the air inlet I 3 for delivery of purification nitrogen, and air inlet I 3 is connecting the jet pipe of nitrogen, the bottom opening of magnesium powder tank 1 and being inserted in conduit 4, and the top of magnesium powder tank 1 bottom opening is provided with stop valve 13. This brace and connecting rod framework 2 comprises crank 5 and connecting rod 6, one end of connecting rod 6 and crank 5 are rotationally connected, the other end of connecting rod 6 is connected with guide rod 7, and on the guide rod 7 and end outside that is positioned at conduit 4 is provided with fairlead 8, has the oil filler point 9 for lubricated guide rod 7 on fairlead 8. The right-hand end of guide rod 7 is connected with the stopper head 10 for pushing magnesium powder, on conduit 4 and the right side opening that is positioned at magnesium powder tank 1 be useful on the air inlet II 11 of carrying purification nitrogen, the other end of conduit 4 is connecting bottom and is being inserted into the Inserting Tube 12 in iron liquid bag. One end of guide rod 7 adopts bearing pin to be connected with connecting rod 6, and the other end adopts and is threaded with stopper head 10, is conducive to maintenance, is convenient for changing stopper head 10.
In order to improve the efficiency of work, realize continuous powder feeding, this automatic powder feeding device comprises the brace and connecting rod framework of two cover alternations.
When work, when reductor driving crank linkage 2, promote stopper head 10 straight reciprocating motions, every action once, just appropriate magnesium powder can be sent in conduit 4, then be pushed Inserting Tube 12 by nitrogen, magnesium powder tank 1 suitable for reading with the powder feeding passage nitrogen jet pipe that is all connected to suitable for reading, overpressure is identical with tank internal pressure, can effectively prevent like this blowback of magnesium powder. when work, can adopt two set crank link structures, two cover plungers replace powder feeding, can realize continuous powder feeding operation. in the time of magnesium powder process desulfurization skimming bag, owing to building partition wall by laying bricks or stones one at inclusion mid portion, iron liquid bag is divided into two parts, partition wall body bottom is built iron liquid by laying bricks or stones and is had a look at, iron liquid bag two parts are communicated with, like this desulfurizing agent is entered from a side, because the liquid-tight degree of iron is greater than desulfurization slag, above the layer that desulfurizing agent forms floats over, when passing desulfurizing agent, looks into iron liquid the desulphurization reaction between iron, this part becomes desulfurization reactor, second half becomes the passage of iron liquid, iron liquid passage leaves row's flowing molten iron mouth, desulfurization chamber one side has dregs discharging valve, the position of dregs discharging valve is higher than row's embolum, when the inner iron liquid level of inclusion is during higher than dregs discharging valve, can realize the continuous desulfurization process of limit deslagging limit desulfurization.
Above embodiment is only to explanation of the present utility model, and it is not to restriction of the present utility model. For a person skilled in the art, it still can be modified to the technical scheme of recording in previous embodiment, or is equal to replacement.
