Abstract

A blow sorting device is provided to prevent pollution of a working environment due to dust, by separately collecting recycling products and the dust through cyclones. A blow sorting device includes a blower(10), an air flowing passage(20), a first cyclone(30), and a second cyclone(40). The blower generates a wind force. The air flowing passage induces recycling products sorted into high-weight and low-weight by using the wind force. The first cyclone separates dust from the low-weight recycling products through the air flowing passage. The second cyclone collects the dust separated by the first cyclone.

Therefore, when the recycled products transported along the main conveyor 1 falls freely at the ends, they are sorted according to the specific gravity by the wind power discharged through the extension pipe 12, and the wind power is adjusted according to the specific gravity of the recycled goods to be sorted. It is configured to do this.

In addition, the installation angle α of the extension pipe 12 is installed in the range of 20 to 50 degrees, preferably in the range of 30 to 40 degrees, most preferably 35 degrees.

The extension pipe line 20 is installed at the end of the main conveyor (1), the first conveying conveyor 22 is installed at the lower end, the upper end of the first introduction pipe 32 of the first cyclone 30 to be described later Connected with

In addition, the extension pipe line 20 is formed to include the ends of the extension pipe line 12 and the main conveyor (1) to prevent the loss of wind power generated in the extension pipe line 22 when installed at the end of the main conveyor (1). In particular, it is a general technical idea that the optimal design is designed so that the vortex phenomenon does not occur inside the extension pipe 20 by the wind power.

The first cyclone 30 has a first introduction pipe 32 connected to the upper end of the ventilation pipe 10 is provided on one side, the second introduction pipe 34 is formed on the other side, the discharge pipe 36 in the lower side And a second transfer conveyor 38 below.

In addition, the second introduction pipe 34 is preferably provided at a position raised to a certain height than the first introduction pipe 32, which is a low specific gravity recycled goods entered through the first introduction pipe 32 enters in a tangential direction. Afterwards, when turning down while riding on the inner wall, the dust mixed in the low specific gravity recycled product can be easily re-introduced into the second introduction pipe 34 by the reverse rise.

In addition, an exit inlet 39 is further configured on the upper surface of the first cyclone 30 to allow the worker to enter and exit, allowing the worker to enter and exit the interior of the first cyclone 30, and the doorway 39. The lid is provided to prevent the introduction of foreign matter.

Meanwhile, a discharge box 310 is further configured below the first cyclone 30, and the discharge box 310 has an inlet pipe 312 and a ventilation hole 313 connected to the discharge pipe 36 formed on an upper surface thereof. The discharge port 314 is formed at one side of the side wall, such that the low specific gravity recycled product introduced through the inlet pipe 312 may be discharged to the second transfer conveyor 38 through the discharge hole 314.

This prevents the low specific gravity recycled products with the wind power falling into the discharge pipe 36 of the first cyclone 30 from scattering, and in particular, the reverse rising air flow in the center of the wind power of the vortex wind having a turning force inside the first cyclone 30. It is to prevent the wind from being diffused at a time so that is smoothly formed.

In addition, the discharge box 310 is formed with a plurality of identification window 316 for identifying the internal state from the outside, the low specific gravity introduced through the inlet pipe 312 in the discharge box 310.

Meanwhile, the first and second cyclones 30 and 40 are preferably formed in a tangential inflow-flow-type in which a cylindrical tube is formed above and a conical tube is formed below. .

The operation state of the wind gravity screening device configured as described above is as follows.

First, separation through the first manual work, recycled products sorted by sorting recycled materials or materials, that is, plastics and bottles fall freely from the end along the main conveyor (1).

And, the wind power generated in the blower 10 provided below the main conveyor (1) is discharged at an angle (α) at the end of the main conveyor (1) through the extension pipe 12, the main conveyor (1) Recyclables falling freely are separated according to specific gravity.

That is, vinyl, paper, shredded plastic, and bottles, which have a relatively lower specific gravity than plastics or bottles and metals, are separated into low specific gravity recycled products, and the high specific gravity recycled materials are not affected by the wind and are freely dropped. Through the first conveying conveyor 22 provided at the bottom of the) is transferred to the next sorting process.

In addition, the low specific gravity recycled products affected by the wind are raised along the ventilation pipe 20 to enter the first cyclone 30 through the first introduction pipe 32.

In addition, the low specific gravity recycled goods entered through the first introduction pipe 32 of the first cyclone 30 are turned downward while turning on the inner wall, and foreign substances, namely dust, etc. caught in the low specific gravity recycled goods.
