Description
Technical field:
The utility model relates to the field of iron ore production and processing, in particular to a screening and discharging structure of mineral dressing tailings.
The background technology is as follows:
Iron is the earliest and most widely used metal in the world, and is consumed in about 95% of the total metal consumption. Iron ore is mainly used in the iron and steel industry for smelting pig iron with different carbon contents.
The tailing treatment process means that tailing slurry output by a beneficiation process is concentrated and then treated by a dehydration vibrating screen device, and the water content of a product on the screen is usually below 20%, so that the product can be directly transported to a fixed place for dry stacking. The tailing screen is vibrating screen equipment for dewatering, the screen of the tailing screen is divided into two parts which are a water discharge screen with an angle of 45 degrees with the horizontal and a plane screen with a negative inclination angle with the horizontal, iron ore to be dewatered is sent to the tailing screen and falls onto the water discharge screen, after the water discharge screen removes about 1/3 of water, the iron ore enters the joint of the plane screen and the water discharge screen, accumulation of materials occurs, tailing mud particles settle by gravity, and a thinner filtering layer starts to be formed; the filter layer prevents other particles from penetrating the screen, so that the filter layer is gradually thickened, water which fails to penetrate the screen forms a water pool at the upper part of the filter layer, and the water is gradually removed under strong movement; because the screen surface is installed at a negative inclination angle, water cannot overflow from the discharge port, and surface water can flow into a water pool of the joint part.
When the production demand is big, the tailing volume that falls to the tailing screen is big, leads to being arranged in the tailing granule of upper strata to pile up in the pond, and the water that is arranged in the pond and the sediment tailing in the pond discharge from the bin outlet fast, leads to still very big behind the tailing screen screening the tailing moisture content, can't directly transport to fixed place and carry out dry-type stack, need carry out the secondary dehumidification, has increased the time of tailing processing, reduces production efficiency.
In order to solve the problems, in a tailing screening device with the patent number of CN210905231U, a water baffle and a water retaining wall are additionally arranged at the existing vibrating screen and used for preventing water from being discharged along a discharge hole, so that the problem that dry materials need to be dehumidified secondarily when the workload is large is solved.
But add the mode of retaining wall and breakwater although can solve water along bin outlet exhaust problem, nevertheless simultaneously, also can hinder the discharge of drier, lead to drier to pile up in the shale shaker department, increased the burden of shale shaker for the load greatly increased of shale shaker has reduced the life of shale shaker.
The utility model comprises the following steps:
the utility model aims to provide a screening and discharging structure for mineral tailings.
The utility model is implemented by the following technical scheme:
The utility model provides a mineral separation tailing screening discharge structure, including the bin outlet of concentrator, the below of the bin outlet of concentrator is provided with collects the hopper, the bin outlet department fixed mounting of concentrator has the row silo, the row silo is U type form, the reflux tank is installed to the bottom of row silo, the reflux tank communicates with each other with collecting the hopper through the back flow, the bottom mounting embedding of row silo has the screen cloth, fixed mounting has the conveyer between the both sides inner wall of row silo, the lateral wall department fixed mounting of row silo has driving motor, driving motor's output and one of them transmission rod fixed connection of conveyer, even fixedly connected with a plurality of baffles on the conveyer belt of conveyer.
Preferably, the side wall of the discharge groove is fixedly connected with an overflow pipe, and the bottom end of the overflow pipe is fixedly connected and communicated with the side wall of the reflux groove.
Preferably, the output end of the driving motor is fixedly provided with a speed changer, the output end of the speed changer is fixedly connected with a corresponding conveyor driving roller, and a conveyor belt of the conveyor adopts chain transmission.
The utility model has the advantages that: the material discharging groove is additionally arranged, the material draining time is increased, the baffle plate on the conveyor is utilized to replace the water retaining wall at the vibrating screen, so that under the condition of large workload, the material is prevented from being piled up at the vibrating screen, the conveyor is enabled to rotate clockwise simultaneously, the dry materials are stably and orderly discharged, the overflow pipe is arranged, the overflow of water carrying tailings is avoided, the backflow collection is carried out through the return pipe, the load at the vibrating screen is reduced, and the influence on the service life of the vibrating screen is avoided.
