COMPARTMENT CONCENTRATOR Russian patent published in 1995 - IPC

FIELD: non-ferrous metallurgy. SUBSTANCE: compartment concentrator has an intake bunker with slide gate and a chute-distributor. A branch pipe for the water adjustment is introduced through the hole in the back wall into the head part of the chute having the definite length. The bottom of the chute is covered with resilient material of the linoleum type. Drawers overlapped with screens having cells of different size are made on the rest part of the bottom with the necessary space. Pipes for the downcast water irrigation are suspended independently over the drawers from above. The enrichment chambers are attached to the bottom under the drawers from below. The chambers are divided along the longitudinal axis by the vertical partition into two compartments: the right one (rear) for collecting the fractions of grey schlich of definite size for enrichment and the left one (front) for storing the reprocessed sand-clay refuse mass and its discharge in the control gate valve through the discharging window in the upper part of the back wall. The displacement of the reprocessed components of the grey schlich from the collecting right compartment to the front left one takes place through the spacing of the necessary size between the lower rib of the vertical partition and the bottom having the oval shape with the slope towards discharging. A drawer with a catch fixture is provided in the lower part of the front wall. A branch pipe for feeding the uptake water flow is introduced through the hole in the lower part of the back wall. The enrichment chamber without a screen for collecting the leftovers of the grey schlich mass to reprocess them and for the direct disposal of the sand-clay refuse mass into the residue is attached to the bottom face of the chute-distributor. All the construction including the chute-distributor, the enrichment chambers and the control gate valve as a whole is suspended in a loose state on the hinged suspensions of the bar type with the adjustable on the hinged suspensions of the rear part with the buffer fixture with the regulated force of the shaking jerks and is brought into the reciprocal motion by the drive with the adjusted length of the linear motion. EFFECT: facilitated manufacture. 1 cl, 3 dwg
