Abstract

PROBLEM TO BE SOLVED: To surely separate light substances and heavy substances in a mixture based on the weight even if these substances are all together magnetic or nonmagnetic by providing an apparatus with a separation chamber, a high speed air jetting means to scatter the thrown mixture of the light substances and heavy substances, outlets for heavy substances and light substances, and a partitioning plate to partition both outlets. SOLUTION: In an apparatus for separating light substances, a mixture of light substances and heavy substances carried by a conveyer 1 is vibrated by a vibration feeder 2 to be scattered and thrown to a separation box 3 through a throwing inlet while being formed into a layer with a constant thickness. At that time, the mixture is scattered horizontally or in slightly upward direction in the separation box 3 by high speed air blown through an air blowing outlet 5. As a result, heavy substances in the mixture fall in a heavy substance outlet 9 part which exists in the front side and light substances are separated by a partitioning plate 11 and fall in a light substance outlet 10. Moreover, fine dust scattered simultaneously is collected by a gas discharging fan 8 installed in an upper part in the other side of the separation box 3 and captured by a filter 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light weight separating apparatus, and more particularly to a light weight separating apparatus using an air flow.

[0002]

2. Description of the Related Art Conventionally, it is known that metal products and non-metal products are separated by using a magnet.

However, in the known means as described above,
There is a drawback in that it is not possible to separate a lightweight material having a small specific gravity and a heavy material having a large specific gravity from products of the same metal material or non-metal material.

The present invention has been made to eliminate the above disadvantages.

[0005]

The light weight separating apparatus of the present invention comprises a separation chamber, a means for causing a mixture of a light weight and a heavy weight to be charged into one side of the separation chamber while applying vibration, and A high-speed air discharging means for scattering the mixed mixture from the one side to the other side in the separation chamber, and a heavy material outlet and a light material outlet formed in the one side lower portion and the other side lower portion of the separation chamber, respectively. It is composed of a branch plate for branching both the outlets, the branch plate having variable length and mounting angle.

Dust collecting means is provided above the separation chamber.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, a lightweight piece such as a paper piece or a vinyl piece having a size of about 10 to 70 mm and a small specific gravity and an aluminum piece having a size of about 10 to 70 mm and a large specific gravity are used. Conveyor 1 for a mixture of heavy objects
Then, the mixture is introduced onto the vibrating feeder 2 and a certain amount of vibration is applied to the mixture, and the mixture is introduced into the separation box 3 from the introduction port 4 at the center of one side of the separation box 3.

On the other hand, below the charging port 4, air having a wind speed of about 12 m / sec is blown from an air blowing fan 6 through an air blowing port 5 formed on one side of the separation box 3, and the charging is performed. The mixture charged from the mouth 4 is scattered in the separation box 3.

An exhaust fan 8 having a filter 7 is provided on the upper side of the other side of the separation box 3, a heavy article outlet 9 is formed on the lower side of one side, and a lightweight article outlet 10 is formed on the lower side of the other side. A branch plate 11 is provided on the inner surface of the bottom wall so that the length between the outlets 9 and 10 and the mounting angle can be adjusted.

Since the lightweight object separating apparatus of the present invention has the above-described structure, the mixture carried by the conveyor 1 is vibrated by the vibrating feeder 2 to be separated into pieces, and the separating box is introduced from the charging port 4 with a constant layer thickness. 3 is put into the separation box 3 by high-speed air from the air blowing port 5 at this time.
Inside the mixture is scattered horizontally and slightly upwards, and as a result, the heavy objects in the mixture fall to the front heavy object outlet 9 portion, and the light objects are separated by the branching plate 11, for example, the light object outlet located 550 mm deep. It will fall to 10.

The fine dust scattered at the same time is collected by the exhaust fan 8 formed on the upper side of the other side of the separation box 3 and captured by the filter 7.

[0013]

As described above, according to the lightweight object separating apparatus of the present invention, there is a great advantage that magnetic materials and non-magnetic materials can be reliably separated depending on whether they are lightweight or not.
