Description

The invention relates to drum slaking machines for lime, using a drum having a wall thermal insulation at the half of its length closest to its entrance and provided with internal shelves. In the proposed apparatus, in addition to the mentioned thermal insulation and internal shelves that serve to mix lime when it is quenched, a special device is used for unloading the device and a fixed 1 bunker connected to the apparatus by means of a sealing ring and having an internal shield under which a cavity forms, to which the exhaust pipe is attached with an irrigation dust separator of the known device.

FIG. 1 of the drawing is given a longitudinal section of the proposed drum apparatus; FIG. 2 shows a detail of the connection of the hopper with the dust separator; FIG. 3 is a detailed view in longitudinal section of the discharge device; FIG. 4 is a top view and in FIG. 5 is a cross-section.

Lime from the hopper 1 (Fig. 1) enters the hopper of the apparatus 2 and, the passage under the flap 3 along the hopper tray enters the drum of the apparatus. The latter is a metallic, on (520)

cling along the lime course, the drum 4 supported by the tires 6 on the rollers 5. The device has a slow rotation transmitted to it through the ring gear 7. The first half of the device along the lime line has a thermal 8. There is a sealing ring 9 in the place of junction with the bunker, not allowing couples to get into the room. The lime that has entered the apparatus is poured into it with water coming through the tube 10. When pouring water, the lime is mixed by the shelves 11 connected and rotated together with the casing 4 of the apparatus. After a good mix of lime and water, the mixture enters the smooth part of the drum, where it strikes forward and quenches. At the same time, for the entire duration of the journey, the mixture is 2-3 times for uniformity of quenching, and is mixed with shelves 12 arranged according to the type of shelves 11. The passed lime apparatus enters the discharge device, the operation of which is as follows. In this apparatus, the lime is maintained at a certain level by a spiral washer 13 (Fig. 3-5) fixed to the walls 4 of the apparatus. The puck has a cut for a certain distance, which follows from the calculation, and as a result, it is one turn of the helix. For each rotation of the apparatus, the helix 13 cuts off a certain portion from the moving lime mass and unloads it into the chute 15. If pieces that cannot be passed through the incision of the helix fall into the lime being unloaded (such pieces can be underage, burnout and rock), unloading them in the following way. A spiral shelf 14 is attached to the inner end of the spiral washer 13, consisting of several rods, fastened at one end to the washer, and the other to a special abutment 14a. The gaps between the rods are made large enough so that small slaked lime can pass between them; pieces of the same size as the half-cut of the washer / and more are picked up by the grid shelf and, when the shelf reaches the position indicated in the drawing by the dotted line, are dropped onto tray 16. When dropped from the blow, the small pieces adhering to the pieces fall off. The pieces themselves on the tray 16 are removed from the apparatus in the direction indicated by the dotted arrow. The vapors formed in the apparatus come out over the lime.

into the hopper 2, where through the cavity formed by the flap 3, they enter the exhaust pipe 17 connected to the dust collector 18 of the known device (Fig. 2).

The subject matter of the invention.

1. A drum lime dresser using a drum having a wall thermal insulation at the half of its length closest to the entrance and provided with internal shelves, characterized in that its drum has a discharge device consisting of a spiral washer 13 fastened to the drum wall and lattice shelves 14, of which the first is designed to separate a portion of the extinguished lime from the mass in the drum itself and to transfer this portion to a fixed outlet chute, and the second to capture large nepogsnvshihs pieces and for dropping them on the stationary grate 16,

 2. When using the apparatus according to claim 1, use of a known irrigation dust collector.
