Description

High recovery concentration table

Technical field

The utility model relates to a kind of shaking table, and the shaking table that especially a kind of ore dressing is used belongs to the benficiation machinery equipment technical field.

Background technology

In ore dressing field, adopt shaking table to sort mostly to the fine particle ore, promptly different according to metalliferous mineral and impurity proportion make ore pulp finish the branch of metal and impurity on the rocking vibration bed surface of shaking table, thereby select useful metalliferous mineral.The shaking table structure of using is so at present: with groove on its face, bed body one end of its side band pulp tank and tank is fixed on the bearing by spring, the other end links to each other with the deceleration engine by the rigidity connecting rod, bed body bottom places on the bearing by slide block, so that finish the rocking vibration of a body under engine driving and spring action; Because the pulp tank of the bed surface side of band longitudinal groove and the bottom land of tank are equipped with through hole, ore pulp and water via through holes are flowed in the groove of bed surface, and in vibration processes, make greatly and move to tailstock than heavy mineral along groove, the impurity of little proportion and mud then flow out with water.It is low that the shaking table of said structure exists the rate of recovery, inapplicable to the difficult ore dressing of some mineral institutional framework complexity especially, thereby restricting the development of ore dressing industry, makes the valency useful metal that has in the refractory minerals can not get effective recovery, causes the waste of mineral resources.Therefore, must be improved prior art.

Summary of the invention

The purpose of this utility model is to provide a kind of rate of recovery height, and the shaking table that can sort the light thin ore particle of difficulty choosing.

The utility model is finished by following technical proposal: a kind of high recovery concentration table, comprise with groove on its face, the bed body of its side band pulp tank and tank, the base of supporting bed body, be fixed on the rigidity connecting rod of a body one end and the power unit that is attached thereto, be fixed on a return spring of the body other end, it is characterized in that the rigidity connecting rod that links to each other with bed body one end is provided with spring, the return spring that links to each other with the bed body other end is fixed on stroke stake one side, stroke stake opposite side is matched with the stop block that is fixed on the body, so that under the power unit drives, the reciprocally swinging of a body is finished in the pulling by connecting rod and the return elastic force effect of spring, especially when return, point type by stroke stake and stop block connects, and return bed body is obstructed and produces the compartment inertia impulsive force, thereby the ore particle on the bed surface is sent a journey forward, and rollback no longer helps improving the rate of recovery of valuable mineral.

Four angles of described bed body bottom place respectively on four corresponding rolling bearings, each rolling bearing is fixed in the slide on the base by the minor axis activity that places, so that the bed body is subjected to roller bearings to finish reciprocally swinging, thereby reduce friction, reduce power consumption.

Described slide is bolted on the base by adjusting, so that adjust the slide height according to actual needs, thereby realizes the adjustment at bed body angle of inclination, to satisfy the ore-dressing technique requirement of different mineral.

The matched position of described bed body bottom surface and rolling bearing is provided with wear-resistant block, in case the wearing and tearing of this position, improves bed body service life.

The pulp tank below of described bed surface side is provided with the branch stock tank, divide the port of export bottom of stock tank to be provided with the outlet of coarse grain ore deposit, the cell wall top of dividing stock tank to be positioned at bed surface one side is interval with particulate ore deposit and impurity diffluence pass, so that the ore pulp that enters in the branch stock tank separates at this, be that big proportion coarse grain ore deposit sinks to the bottom the back directly imports bed surface through the outlet of coarse grain ore deposit along bottom land concentrate position, shorten the concentrate path, tiny grain ore deposit and impurity then enter bed surface by minute diffluence pass on stock tank top, wherein mud and fine impurities flow out bed surface with slurries, middle particulate thing then sinks in the bed surface groove, rocking vibration and inertia force effect through the bed body, make heavy middle particulate ore deposit continue to proceed to the concentrate position of bed surface again, the impurity that proportion is little then flows out bed surface with water, thereby realizes that concentrate sorts.

The tank below of described bed surface side is provided with bypass channel, and the cell wall top that bypass channel is positioned at bed surface one side is interval with the bleeder, so that current enter bed surface equably and take the impurity on its top out of bed surface.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can make the ore pulp that enters before the bed surface in minute stock tank, finish separating of coarse grain ore deposit and particulate ore deposit in advance, promptly allow of the coarse grain ore deposit outlet of coarse grain ore deposit directly import the concentrate position of bed surface through minute stock tank port of export bottom, shorten the concentrate path, improve beneficiating efficiency, simultaneously tiny grain ore deposit and impurity then evenly enter bed surface by minute diffluence pass on stock tank top, make wherein mud and fine impurities flow out bed surface with slurries, medium and small particulate thing then sinks in the bed surface groove, spring action by pull bar on the bed body and two ends, eliminate the bed body and move back and forth the impulsive force that is produced, make mineral back and forth shaking and finish big with the bed body on bed surface; the separation of little proportion ore particle; and make only rollback not of ore particle; the especially point type inertia force effect by stroke stake and stop block; a journey is sent in heavy medium and small particulate ore deposit forward and rollback no longer; move back the modes in two steps and compare with the shaking table of prior art three steps of advancing when sorting concentrate; not only beneficiating efficiency is improved; some very difficult mineral that select are thoroughly sorted, and has greatly improved the concentrate rate of recovery and concentrate grade to moving ahead.By the support of bed body bottom rolling bearing, effectively overcome bed body rocking vibration resistance in addition, only can drive a body rocking vibration with low-power machine, reduce power consumption to greatest extent, help saving energy and reduce the cost while good operation stability, reliability height, both be suitable for sorting easy ore dressing thing, be more suitable in sorting refractory minerals, and can improve the ore dressing day output, reduce beneficiation cost, effectively reclaim available ore deposit, allow limited mineral resources be fully used.
