Description

Purification device for firing systems charged with solid fuels The invention relates to a purification device for solid fuels Charged combustion systems with one suspended pendulum underneath the slag chute Slag pan, the pendulum movements of which carry the slag to one side will.

In a known embodiment of this type, a slag hopper protrudes in a trough filled with water, so that the slag through this slag funnel can get into the hollow first. The trough vibrates; the trough associated with it is a shovel, which is also driven to oscillate, and which carries the slag for example in one direction from the trough into a funnel and then swings back into the starting position, with the shovel folded down and fed back and thereby the slag is not promoted.

The disadvantage of this embodiment is that two drive units (for the shovel and for the trough) are required and rotating elements through the Slag must be carried out, which is known by their acid or base content attacks these parts, whereby their mobility suffers.

In another embodiment, the vane is tubular Elements guided and driven. The tubes allow the shovel to get out of the Move the slag sump upwards when there is resistance to avoid damaging it. However, this embodiment has the disadvantage that the entire mechanism is complicated and is therefore very prone to failure. In addition, the are arranged on the funnel Sealing flaps with the greatest probability of the falling slag laterally pushed up so that they can only partially fulfill their intended task.

The described disadvantages counteracts the invention in that a Slider that can be moved up and down in an approximately vertical plane via a lever linkage is coupled to the tub such that at the beginning of the pivoting back of the tub the slide is in its lower dead position or in this direction moves while he begins to pivot the tub forward into the upper Dead position moved.

This measure according to the invention fulfills the task set according to which the combustion residues (slag) are to be extinguished, the residues are to be discharged and the furnace is a clear seal against the outside air must experience in a comprehensive way.

Particular advantages are that for moving the slide and the Only one drive tub is required, with all moving parts outside of the slag sump are located; in addition, a function is beneficial Relative movement generated between the tub and the slide, d. i.e., through the use of the positively controlled slide, which can be moved up and down, is always in the correct position Point in time of the combustion residue tapped.

Through the relative movement between the tub and the slide, the Pan a larger swing when the downward movement of the slider is inhibited is.

The coupling between the slide and the tub should preferably be by means of an angle lever rotatably attached to the outside of the tub can be produced, on one lever arm of which the crank drive for pivoting the tub and on it another lever arm engages the lever system for the movement of the slide. Appropriate you will assign a stop to the angle lever for forward and reverse.

Further details of the invention emerge from the drawing and the description.

The slag parts fall through a chute into one below pendulum suspended and filled with water tub 2, where the falling slag in which water is quenched. An outside of the chute, inevitably over Linkage slide 1 which can be moved up and down approximately vertically abuts approximately at the beginning the pan movement to the left into the slag that is in the pan; latter is when the tub retreats (i.e. subsequently) from slide 1 over edge 14 discharged from the tub.

At the same time, the left part of the tub moves under the chute so that the slag can fall into this tub area; the slide 1 thus separates the slag falling from the shaft into the trough 2 from the slag which is discharged over the edge 14 of the trough 2.

For example, when the tub movement is reversed (i.e. when it returns to moved to the right) the slide is pulled up, otherwise it will be the newly collapsed Slag would be in the way.

The device is driven by the crank mechanism 4; The path 3 of the driver pin of the crank drive 4 is indicated. The drive rod 5, which engages on one side of the angle lever 6, is fastened in this crank pin (without reference symbols). The angle lever 6 is mounted at 10.

At the other end of the angle lever 6, the movement of the crank mechanism 4 is conveyed to the slide 1 via a linkage 7 (with pivot point 11), 8, 9.

The pivot point 10 of the angle lever 6 is located on the tub, while the pivot point 11 of the double-armed lever 8 is located on the shaft. The tub 2 is also suspended in this pivot point 11.

The stops 12 and 13 for the angle lever 6 are on the tub 2 intended.

The drive of slide 1 and tub 2 is coupled in such a way that that with a possibly changed (inhibited) movement impulse a of the slide after at the bottom (e.g. from cinder blocks) the tub generates a greater movement impulse d (Deflection to the left) experiences as a relative movement, which in particular causes damage the slide, but also all other components is avoided.

Claims (6)

Claims: 1. Slagging device for firing systems charged with solid fuels with a slag pan suspended under the slag chute, the pendulum movements of which remove the slag to one side. characterized in that a slide (1) which can be moved up and down in an approximately vertical plane is coupled to the tub (2) via a lever linkage in such a way that when the tub begins to pivot back, the slide is or is in its lower dead position moves in this direction while moving into the top dead center as the tub begins to pivot forward. 2. Purification device according to claim 1, characterized in that the drive for the tub (2) and the slide (1) together via a crank mechanism (3) or. the like. 3. Purification device according to claims 1 and 2, characterized in that the coupling between the slide (1) and tub (2) effecting lever linkage allows a relative movement between the tub and the slide in such a way that the tub executes a greater swivel deflection, when the downward movement of the slide is inhibited. 4. Purification device according to claims 1 to 3, characterized in that the coupling between Slide (1) and tub (2) by means of a rotatably attached to the outside of the tub Angle lever (6) is made, on one lever arm of which the crank mechanism for pivoting the tub and on its other lever arm the lever system for moving the slide attacks. 5. Purification device according to claim 4, characterized in that that the angle lever (6) is assigned a stop (12, 13) for the forward and reverse movement is. 6. Purification device according to one or more of claims 1 to 5, characterized in that the slide (1) is guided on the outside of the chute.
