Abstract

Use: enrichment of solid minerals in heavy media, m. used in coal, mining and other industries. SUMMARY OF THE INVENTION: a heavy middle drum separator is supplemented with a conveying and discharging device for a pop-up product of reciprocating action, interacting with a pop-up product over the entire area of the enrichment bath 5 and at the overflow threshold of the drum, consisting of a rectangular rectangular frame 7 mounted in the grooves of the bed with the possibility of moving along the separator from the drive return

but progressive action. The device is equipped with rollers 8 located across the enrichment bath 5. A rectangular carriage 10 is mounted on the frame with the possibility of movement along the frame,

on which the paddles 11 are fixed on flexible links interacting with the frame rollers, as well as the locking element 12 for positioning the carriage relative to the frame. 1 s.p., f-ly, 3 ill.

The invention relates to the field of enrichment of solid minerals in severe environments and can be used in coal, mining and other industries.

The purpose of the invention is to increase the performance of the separator.

This goal is achieved by the fact that the known separator, drum drive, track rollers, discharge chute, enrichment bath and bed are supplemented with a conveying and discharging device of the pop-up product of reciprocating action, interacting with the pop-up product over the entire area of the enrichment bath mirror and overflow the threshold of the drum, consisting of a flat frame of a rectangular shape mounted in the grooves of the frame with the possibility of movement along the separator from the drive reciprocating VI, equipped with rollers located across the enrichment bath. A rectangular carriage is mounted on the frame, with the possibility of moving along the frame, on which are mounted the ridges on flexible links interacting with the frame rollers, as well as a fixing element for positioning the carriage relative to the frame.

The introduction of a transporting and unloading device into the separator design will make it possible to create a forced process for transporting the surfaced product along the enrichment bath, independent of the speed of the transporting suspension flow, which, combined with forced unloading of the product through the drum threshold, will increase the overall performance of the separator, because increasing productivity on a sunken product is achieved by simply increasing the rotational speed of the drum. In addition, the strokes provide for unloading from the drum through the overflow threshold and large pieces of the surfaced product, which could not be unloaded from the drum only by a stream of suspension.

Figure 1 shows a drum separator in longitudinal section with a device for unloading a light fraction; figure 2 - carriage of the unloading device light

fractions at the beginning of the working stroke; in Fig.Z - at the end of the stroke.

The separator contains a drum 1 mounted on the track rollers 3, an unloading tray 4, an enrichment bath 5,

bed b, on which all parts of the separator are mounted. A transporting and unloading device is installed on the beams of the bed 6, including a frame 7 with rollers 8 and a drive 9. A carriage 10 is mounted on the frame, on which the legs 11 and the fixing element 12 are fixed. The stops 13 and the carriage release element 14 are installed on the frame.

The separator works as follows.

The enrichment product, supplied together with the heavy medium to the enrichment bath 5, is divided in the heavy medium by density into two products - the pop-up and

drowned. The sunken product is lowered to the bottom of the drum 1 and, when the drum is rotated, is lifted by the lifting elements of the drum from a heavy medium and unloaded along the discharge chute 4. The product that has surfaced in a heavy medium is caught by the raggs 11 and during the working stroke of the frame 7 with the carriage 10 (towards the overflow threshold) forced moves with strokes to unload, and then is unloaded from the drum through

overflow threshold. At the end of the stroke of the frame 7, the carriage 10 is delayed by the stop 13, and the frame 7, while continuing its progressive movement, presses the pendants of the strokes with the rollers 8 to remove them from the heavy medium. In that

the position of the carriage 10 is fixed relative to the frame 7 by the latch 12. The relative position of the frame and the carriage at the end of the stroke is shown in Fig. 2.

At the end of the idle (reverse) stroke of the frame 7, the latches of the carriage 12 are lifted by the unlocking element 14 of the carriage, and the stop 13 moves the carriage along the frame 7 and

set to working position. At

the movement of the frame 7 with the carriage 10 forward (to the left in Fig. 1) is the working stroke described earlier. Thus, the forced movement of the surfaced product is carried out along the entire length of the enrichment bath and at the overflow threshold, which ensures an increase in the separator productivity and an increase in the upper size limit of the material being enriched.

Claims (2)

SUMMARY OF THE INVENTION 1. A device for unloading a light fraction from a drum heavy middle separator, comprising paddles mounted to move in a separator bath located on a bed with Fig 2 0 5 grooves, characterized in that, in order to increase the capacity of the separator, it is equipped with a flat frame / placed in the grooves of the bed with the possibility of reciprocating movement along the bath, rollers located on the frame across the bath, and a rectangular carriage mounted with the ability to move along the frame and fix on it, while ridges interacting with the frame rollers are fixed to the carriage. 2.
