Description

A dust separator of aggregate

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aggregate differentiating separator having a new structure capable of effectively separating fine particles contained in an aggregate.

Generally, aggregates used in construction are produced by crushing natural rocks with a crusher or the like. At this time, a large amount of fine particles are contained in the aggregate.

Therefore, after producing such an aggregate, an aggregate and a fine powder are separated using an aggregate differentiator.

As such, in the aggregate differentiating separator used for separating the aggregate and the fine powder, it is common to separate the aggregate and the fine powder by using a mesh net having a plurality of fine eyes. Such an aggregate differentiating separator has low separation efficiency, There is a problem that the mesh of the mesh network is clogged.

Recently, various kinds of aggregate differentiating apparatuses as shown in many precedent documents including the registered patent 10-0552351 and 10-0878842 have been developed. However, such an aggregate differentiating separator also effectively separates aggregates and fine particles There is a problem that it is difficult to do.

Accordingly, the present applicant has developed an aggregate differentiating separator for separating an aggregate and a fine powder using a separating conveyor (21, 22) provided so as to extend laterally.

1 and 2, the apparatus includes a support frame 10, separation conveyors 21 and 22 extending in the lateral direction to the support frame 10, separation conveyors 21 and 22, 22), and aggregate supply means (40) for supplying aggregate containing fine particles to the upper surfaces of the separation conveyors (21, 22), which are located above the separation conveyors (21, 22) , 50), and first and second discharge conveyors (60, 70) provided below the separation conveyors (21, 22).

The separation conveyors 21 and 22 are composed of an upper first separation conveyor 21 and a lower second separation conveyor 22.

The first and second separation conveyors 21 and 22 include a pair of support rollers 23 spaced from each other in the lateral direction of the support frame 10, And a drive motor 25 connected to the support roller 23 to drive the support roller 23 so that the upper surface of the belt member 24 is inclined downward forward .

The drive motor 25 drives the support roller 23 so that the upper surface of the belt member 24 is circulated from left to right.

A scrapper 26 for scraping off the fine particles attached to the belt member 24 is provided at the right end of the first and second separation conveyors 21 and 22.

The water jetting means injects water to the belt member 24 of the first and second separation conveyors 21 and 22 using an injection nozzle 31 provided on one side of the upper surface of the separation conveyor 21, .

At this time, when the water is sprayed to the first and second belt members 24, the belt members 24 of the first and second separation conveyors 21 and 22 are wetted to the aggregate supplying means 40 and 50 The fine particles supplied together with the aggregate adhere to the surface of the belt member 24, whereby the aggregate and the fine particles are separated.

The aggregate supplying means 40 and 50 are connected to a supply hopper 40 provided on the upper left side of the first separating conveyor 21 and a supply unit 40 connected to the supply hopper 40 for supplying aggregate containing fine particles And a conveyor 50. The aggregate containing fine particles can be supplied to the upper surface of the first separation conveyor 21.

The first discharge conveyor 60 is provided to extend from the lower side of the second separation conveyor 22 to the left and the second discharge conveyor 70 is disposed below the right end of the second separation conveyor 22 And extend rearward.

Therefore, water is sprayed to the first and second separation conveyors (21, 22) using the water injection means, and in a state in which the first and second separation conveyors (21, 22) When the aggregate material mixed with the fine particles is supplied to the upper surface of the first separation conveyor 21 using the feeding means 40 and 50, the heavy aggregate is conveyed to the belt member 24 of the first and second separation conveyors 21 and 22 And is discharged to one side through the first discharge conveyor 60. The light differential is discharged to the side of the belt member 24 of the first and second separation conveyors 21, And then dropped by the scrapper 26 and dropped downward, and is discharged through the second discharge conveyor 70 and removed.

Therefore, the heavy aggregate and the light fine powder can be effectively separated, and only the fine powder can be selectively removed.

The aggregate separating apparatus supplies the aggregate containing the fine particles by using the supply conveyor 50 of the aggregate supplying means 40 and 50. At this time, the fine particles are supplied while being attached to the aggregate, It often occurs that the separation can not be performed smoothly.

Particularly, in order to effectively separate the fine powder and the aggregate by using the aggregate differentiating separator, the aggregate and the fine powder must be supplied to the separation conveyors 21 and 22 so as to spread widely. And a supply conveyor 50 connected to the supply hopper 40 and supplying an aggregate containing fine particles. The aggregate and the fine particles supplied to the supply conveyor 50 There is a problem in that it is difficult to spread aggregates and fine powders widely while being able to supply the precise positions of the separation conveyors 21 and 22.

Therefore, there is a need for a new method for solving such problems.
