Description

Aggregate sorting device

The present invention relates to a sorting device for waste aggregates, and more particularly, to an aggregate sorting device capable of classifying waste aggregates obtained by crushing construction waste while flowing through a network cylinder.

In general, construction wastes are wastes generated by dismantling structures such as buildings, bridges, and roads. Recently, construction wastes are widely known.

First, in the case of regenerating construction wastes universally, the construction wastes are first crushed in a lump form, and the reinforcing bars are separated from the crushed crushed matters.

In the crushed matter, the aggregate that can be recycled into aggregate is put into a crusher and then crushed into secondary particles. Next, the crushed aggregate (hereinafter referred to as aggregate) is put into an aggregate sorting apparatus and sorted by size. And finally to remove the foreign substances while washing the classified aggregates with wash water to produce recycled aggregates.

The present invention is to improve the aggregate sorting device by the size of the aggregate, first described the conventional aggregate sorting device as follows.

Conventionally known aggregate sorting apparatus is provided in the upper portion of the base in front and consists of a mesh cylindrical body that rotates itself through a drive to filter the aggregate, and a conveyor for introducing aggregate into the mesh cylindrical rear input portion. The drive unit for rotating the mesh cylinder is composed of a sprocket provided around the mesh cylinder and a drive motor connected to the sprocket by a chain to rotate the sprocket.

In addition, the lower front, rear of the mesh cylinder is supported by a plurality of rollers to enable the rotation of the mesh cylinder.

In addition, the front and the lower portion of the mesh cylindrical body is provided with a conveying conveyor for transporting the aggregate filtered through the mesh and the aggregate passed through the mesh.

Therefore, when the aggregate is introduced into the inside of the mesh rotating body through the conveyor while rotating the mesh rotating body through the operation of the driving unit, the aggregate having a larger particle size than the mesh is discharged and transported forward, and the aggregate having a smaller particle size than the mesh By passing through and discharged to the bottom, the aggregate can be selected according to the particle size.

However, when the aggregate is selected using the mesh cylinder, as the aggregate remains in the mesh eye, the screening effect of the aggregate is lowered.

In addition, in selecting aggregate using the mesh cylinder, aggregate aggregates concentrated on the input side into which aggregate is input. Therefore, aggregate is accumulated on the input side, and thus, the aggregate is added to the input side is discharged directly without being selected, there is a problem that the precise selection of the aggregate is impossible.

In addition, when the aggregate is concentrated in the input unit as described above, there is a problem that the phenomenon of intensively damaging or clogging the net on the input side due to the weight of the aggregate occurs frequently.

Thus, the present invention is designed to solve the above problems, the present invention is to prevent the phenomenon that aggregates are screened in the mesh eye by flowing the mesh cylinder, aggregate selection can prevent the degradation of the screening effect of aggregates It is an object to provide a device.

In addition, it is an object of the present invention to provide an aggregate sorting device to prevent the aggregates from being unevenly laminated to the lower portion of the aggregate input unit by supplying the aggregate evenly distributed into the network cylinder.

When the shake generating shaft 25 is driven up and down by the centrifugal force generating plate 24 according to such a configuration, the drive motor is driven by the chain connecting means 26 connecting the shake generating shaft 25 and the drive motor 23. The flow plate 221 to which the 23 is fixed is rotated. That is, when the shake generating shaft 25 is raised and lowered, the fluid plate 221 on which the drive motor 23 is fixed is lifted by the chain connecting means 26.
