Abstract

The utility model relates to equipment for dressing gold ore by using double-layer water flow. The inner part of a barrel-shaped container of the utility model is provided with a stirring shovel rotating in a high speed and a porous-shaped damping baffle which is fixed on a barrel wall. Owing to the accomplishment of double-layer and double-speed water flow, the utility model can increase ore dressing precision and can increase the recovery rate and the recovery speed of gold simultaneously. In addition, the utility model has the advantages of simple structure, convenient operation, low cost and reliable work.

Description

The equipment of double-layer water stream sorting gold ore

The utility model relates to a kind of gravity separation device.

At present the gravity separation method device mainly be with ore in sand form to be selected in modes such as stirring, vibration or pulsation with after WATER AS FLOW MEDIUM is fully mixed, utilize again in the ore in sand form to be selected, the different principle of material sinking speed in aqueous medium that proportion is different reaches the purpose of separation ore-sorting.But the limitation of prior art is can not solve fully to mix again the better contradiction of sedimentation, stirs or vibration as increasing, and when increasing mixed effect, has weakened the sedimentation separation effect and has caused flight of gold; Stir or vibration otherwise reduce, when increasing the sedimentation separation effect, weakened mixing effect inevitably, cause finished product ore deposit purity to descend.

The purpose of this utility model is the equipment that a kind of simple in structure, reliable operation will be provided, and reaches to produce double-deck, double speed current, can improve mixing of ore in sand form to be selected and aqueous medium effectively, can improve the effect of weight ore deposit sedimentation separation again.

The purpose of this utility model is that the technical scheme by Fig. 3 realizes: aqueous medium and ore in sand form to be selected are constantly dropped into barrel containers 1 through feed hopper 12, in the bucket 1 high-speed rotating shaft 2 is set vertically, axle 2 lower ends are fixing with stirring shovel 3, stirring outside shovel 3 rotating ranges, along bucket wall vertical fixing porous shape baffle plate or wire netting 4, on the bucket wall on the narrow limit of a side, open a hole, discharge nozzle 10 is installed, stir shovel 3 axis deviation rectangle bung centers, direction is the direction away from discharging opening 10.When the stirring shovel rotates at a high speed, the water that promotes shovel leaf one side is that the center rotates at a high speed with the shovel rachis heart, formation is the high speed rotary water current district at center with the shovel leaf, high-velocity flow drives bucket end ore in sand form and constantly sneaks into the high speed rotary water current, ore in sand form is fully mixed with aqueous medium, and constantly to the axle center inner rotary, before rotary water current reaches barrel wall, run into perforated baffle or wire netting 4, current are hindered during by perforated baffle or wire netting 4, under damping action, lower flow velocity, make near this layer current of bucket wall and do low-speed rotation, form the low speed water district.In low speed water, the rapid sedimentation of heavy Jinsha, at the bottom of the accumulation barrel, the ore in sand form sinking speed that proportion is little is slow, in the water in suspension, constantly toward barrel in water filling, when the water surface 5 exceeded discharging opening 10, the ore in sand form that proportion is little overflowed from discharging opening 10 with water.Shovel axis deviation bung center is stirred in rotation, and away from discharging opening 10, plays the effect that increases settlement space, can further improve the gold rate of recovery.When ore dressing finished, the finished product ore deposit can be taken out with water from bucket bottom valve 6.

Key of the present utility model is: in a simple integral device structure, realized the new technology of the fast current of double-deck double fluid, it is serious to have overcome when water flow velocity is big in the prior art flight of gold, or water flow velocity hour ore in sand form can not get the shortcoming of abundant sorting, reached high speed selected, accelerate ore dressing speed, reduce flight of gold, improve the purpose of finished product ore deposit purity.

Fig. 1 and Fig. 2 are that the master who implements the integral device structure of the utility model example looks schematic diagram and schematic top plan view: on a combining structure framework 7, and fixing bucket formula container 1.Motor 8 and bearing block 9 are fixing with framework 7 respectively, the power of motor 8 is passed to rotating shaft 2 by belt pulley and belt, rotating shaft 2 is fixing by bearing and bearing block 9, rotating shaft 2 lower ends are fixed with stirring shovel 3, and power is passed to stirring shovel 3, and it is rotated at a high speed, feed hopper 12 is fixed with group frame, and the feed hopper outlet is stretched in the bucket, and the bucket wall has light ore deposit discharging opening 10, and heavy ore deposit discharging opening 11 and ball valve 6 are established in the bucket end.

During work, close barrel bottom valves 6 earlier, continuously to feed hopper 12 water fillings, and actuating motor 8, when discharging opening 10 places there are flowing out, can will treat that ore dressing repeatedly adds feed hopper 12, light ore deposit and water constantly flow out from discharging opening 10, and water can be recycled through precipitation.After above-mentioned work is finished, close motor 8, open barrel bottom valve 6, can obtain the finished product ore deposit from discharging opening 11.
