Description
Technical Field
The utility model relates to the field of ore production, in particular to an ore screening device.
Background
Ore refers to a collection of minerals from which useful components can be extracted or which themselves have some property that can be exploited. Can be classified into metallic minerals and nonmetallic minerals.
The ore itself is mixed with a lot of silt after being mined and is of different sizes, and if larger ore is sent to a crusher with smaller power for crushing, the machine cannot operate normally or even is damaged. The utility model discloses a CN202111546657.4 ore screening plant for mineral processing, which comprises an ore screen integral structure, the ore screen integral structure comprises an ore main screening bin, an ore screening net rack, an ore screen supporting seat and a screen plate cleaner, the ore main screening bin comprises a screening bin body, the ore screening net rack is arranged in the screening bin body, the ore screening net rack divides the interior of the screening bin body into a bin body screening chamber and a fine material blanking chamber, the ore screen supporting seat is arranged below the screening bin body, the sieve plate cleaner is arranged right below the corresponding ore screen plate in the screening bin body, the screen plate cleaner is held by hands to roll in a cleaner chute, and the protrusions on the surface of the screen plate cleaner can be used for carrying out penetrating cleaning on a rectangular groove in the ore screen plate, so that the cleaning is quick and convenient, and the span of the screening bin body is not considered; meanwhile, the split type ore screen plates are spliced, so that when the ore screen plates are damaged locally, the whole ore screen plates need to be replaced. The disadvantage of this apparatus is that the poor separation effect is caused by the poor ore transport and the lack of a silt separating structure.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and adapt to the actual needs, and provides an ore screening device which comprises a screening frame, an upper screening part and a lower screening part, wherein a plurality of screening rollers are horizontally arranged on the upper screening part, gaps for dropping sand and small ores are reserved between each screening roller, and a large ore flushing nozzle is arranged on one side above each screening roller; the lower screening part is provided with a small-block ore conveying belt, the belt surface of the small-block ore conveying belt is of a metal net structure, the small-block ore conveying belt is driven to rotate by a plurality of rotating shafts, and a mud box is arranged below the small-block ore conveying belt.
The screening roller is provided with a plurality of material stirring plates along the length direction of the screening roller.
The stirring plate is made of metal.
The stirring plate is hexagonal.
The material stirring plates on the two adjacent material sieving rollers are arranged in a staggered manner.
The small ore conveying belt is obliquely arranged, the middle part of the small ore conveying belt is inclined towards the upper end of the conveying direction, and the two end parts of the small ore conveying belt are horizontally arranged.
The transmission starting end of the small ore conveying belt is positioned in a sludge box, and cleaning water is arranged in the sludge box.
The utility model has the beneficial effects that:
the device can separate massive ores from small ores, the large ores are washed in a spraying mode due to large volume, and the small ores are soaked and washed in a small mode.
Drawings
The utility model is further described below with reference to the drawings and examples.
FIG. 1 is a schematic front view of the present utility model;
FIG. 2 is a top view of the present utility;
fig. 3 is an internal cross-sectional view.
Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
see fig. 1-3.
The utility model discloses an ore screening device which comprises a screening frame 1, an upper screening part 2 and a lower screening part 3, wherein a plurality of screening rollers 21 are horizontally arranged on the upper screening part, gaps for dropping sand and small ores are reserved between the screening rollers 21, and a large ore flushing nozzle 4 is arranged on one side above the screening rollers; the lower screening part is provided with a small-block ore conveying belt 5, the belt surface of the small-block ore conveying belt is of a metal net structure, the small-block ore conveying belt is driven to rotate by a plurality of rotating shafts 51, and a mud box 6 is arranged below the small-block ore conveying belt.
The screening roller is provided with a plurality of material stirring plates 7 along the length direction.
The stirring plate is made of metal.
The stirring plate is hexagonal. The hexagonal stirring plate can increase pushing force for massive ores so that the ores can be quickly pushed and sent out.
The material stirring plates on the two adjacent material sieving rollers are arranged in a staggered manner.
The small ore conveying belt is obliquely arranged, the middle part of the small ore conveying belt is inclined towards the upper end of the conveying direction, and the two end parts of the small ore conveying belt are horizontally arranged.
The transmission starting end of the small ore conveying belt is positioned in a sludge box, and cleaning water is arranged in the sludge box.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent changes or direct or indirect application in the relevant art utilizing the present specification and drawings are included in the scope of the present utility model.
