Registered Patent No. 10-2293348 Registered Patent No. 10-0631034

Conventional technologies for sorting out low-specific gravity foreign substances (vinyl, Styrofoam, etc.) are methods using cyclones or blowing, which makes it difficult to select foreign substances attached to soil and ultimately causes problems that arise when soil containing foreign substances is used as is. , there are problems such as requiring additional work to remove foreign substances from soil.

The present invention is intended to solve the problems described above, and removes low-density foreign substances attached to recycled soil through physical impact to increase the removal efficiency of low-specific gravity foreign substances using subsequent eddy currents and to produce high-purity recycled soil. The purpose is to provide a device and method for removing low-specific gravity foreign substances using rotating vortices and producing recycled soil during the intermediate treatment process.

In the intermediate treatment process of construction waste according to the present invention, the device for removing low-specific gravity foreign substances and producing recycled soil using rotating vortices removes low-specific gravity foreign substances contained in the circulating soil through scattering by the rotating dispersion unit and collision with the liner. It is characterized by first separation and discharging the firstly separated low-specific gravity foreign substances in a vortex atmosphere.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

As shown in Figures 1 and 2, the device for removing low-specific gravity foreign substances and producing recycled soil using rotating vortices during the intermediate treatment process of construction waste according to the present invention removes low-specific gravity from recycled soil (hereinafter abbreviated as 'soil'). The case 10 provides a space to separate foreign substances (vinyl, Styrofoam, etc., hereinafter abbreviated as 'foreign substances'), and is mounted on the inside of the case 10 to scatter soil and foreign substances to the inner wall of the case 10. A rotating dispersion plate 20 that separates each other through physical impact, and a vortex rotor ( 30).

The case 10 has a cylinder structure such as a circle with a space inside and includes an inlet 11, a soil outlet 12, and a foreign matter outlet 13. The inlet 11 is formed on the periphery toward the side and contains the soil and sand outlet 12. The discharge port 12 and the foreign matter discharge port 13 are open toward the bottom and top, respectively.

The case 10 can be a single body, but it can also be divided into two or more parts for assembly and maintenance of the rotating dispersion plate 20 and the vortex rotor 30, for example, the inlet 11. It is divided into a lower case including a soil discharge port 12 and a rotating dispersion plate 20 installed therein, and an upper case including a foreign matter discharge port 13 and a vortex rotor 30 installed therein, and the lower case The case and the upper case can be assembled with bolts and nuts through flanges at the upper and lower parts facing each other.

The case 10 includes a liner 14 on the inner peripheral surface of the place where the rotating dispersion plate 20 is installed, and the liner 14 collides with soil and foreign matter scattered by the rotating dispersion plate 20. It allows soil and foreign matter to separate from each other, and is made of high-strength materials such as high manganese to minimize damage in the event of such collisions.

The liner 14 is preferably a flat plate and has a structure including a plurality of protrusions protruding toward the center at regular intervals along the circumferential direction, that is, a convex-convex structure.

The foreign matter outlet of the case 10 may include a discharge guide 15 to induce rapid discharge of foreign substances and prevent backflow. The discharge guide 15 is arranged along the circumferential direction, and one side is fixed to the inner peripheral surface of the foreign matter discharge port 13, while the other side is inclined upward to reduce the path of the foreign material discharge port 13, thereby increasing the flow speed and leading to the rapid discharge of foreign materials. In addition, because the angle prevents foreign substances from falling toward the vortex rotor 30, it is possible to prevent backflow.

The discharge guide 15 includes a ventilation hole 15a through which air passes to provide fluidity to foreign substances accumulating at the top.

As shown in Figures 2 and 3, the rotary distribution plate 20 has a distribution plate body 21 whose upper surface slopes downward from the center to the edge, and the inclined portion of the distribution plate body 21 moves in the circumferential direction. A plurality of scattering guide wings (22) are arranged along the edge and slope downward to disperse the soil to the liner (14), and are formed to protrude higher than the scattering guide wings (22) at the center of the dispersion plate body (21) to scatter the soil and sand. It is rotatably mounted on the inside of the case 10 through a support frame, etc., with a gap between the liner 14 and the dispersing rod 23 for dispersing the soil, and is connected to a driving means to rotate.

The dispersion plate body 21 causes soil and foreign matter to fall and scatters the soil and foreign matter through rotational force. At this time, the inclined portion is inclined at an angle toward the liner 14 to scatter the soil and foreign matter toward the liner 14. This is the angle that induces the soil to fall into the soil discharge port (12).

The scattering guide wings 22 are formed on the inclined portion of the dispersion plate body 21 to protrude beyond the inclined portion at a certain distance from each other along the circumferential direction, and can be both straight and curved, and the dispersion plate body 21 While rotating, soil and foreign matter are scattered to the liner (14). That is, in the case of the dispersion plate body 21 with a flat upper surface without the scattering guide wing 22, soil and foreign matter may slip and fail to fly toward the liner 14, and the scattering guide wing 22 solves this slippage. do. Ultimately, the dispersion plate body 21 and the scattering guide wing 22 are uneven dispersion plate bodies.

It is preferable that the upper surface of the scattering guide vane 22 has the same angle as the inclined portion of the dispersion plate body 21, but it is not necessarily limited to this.

The dispersion rod 23 is preferably cone-shaped and protrudes upward from the scattering guide vane 22 at the center of the dispersion plate body 21, and prevents the soil and foreign matter from concentrating and stagnating in the center when the soil and foreign matter falls. It helps block soil and foreign matter from scattering into the liner (14).

The driving means includes, for example, a drive motor installed on the outside of the case 10, a belt as a power transmission means that is connected to the drive shaft of the drive motor and the rotary distribution plate 20 to transmit rotational force, and other As an example, a gear train instead of the belt is also possible.

As shown in FIGS. 2 and 4, the vortex rotating body 30 is for forming a vortex toward the foreign matter discharge port 13 on the upper part of the rotating dispersion plate 20, and is preferably cylindrical and has a plurality of vortices formed on the inner peripheral surface. A vortex blade 31 is included, and is rotatably mounted inside the case 10 through a support frame or bearing, and rotates through a driving means, and the driving means is the same as the driving means of the rotating dispersion plate 20. It is also possible to configure it in a similar way, share the drive motor, and add only the power transmission means. In the drawing, the vortex rotor 30 is shown as a circular frame at the top and bottom, but the peripheral portion is omitted to show the vortex blades 31, and a barrel structure with a closed peripheral portion is also included.

During the intermediate treatment process of construction waste according to the present invention, the method of removing low-specific gravity foreign substances using rotating vortices and producing recycled soil is as follows.

1. Input.

A mixture of soil and foreign matter is injected into the inside of the case 10 through the inlet 11 using a conveyor belt, etc. At this time, the mixture introduced is, for example, 8 mm or less.

2. First-order variance.

Since a vortex atmosphere is created through the vortex rotator 30 at the inlet (11), it is possible to sort out soil and foreign matter immediately after injection, and soil and foreign matter with a large specific gravity are rotated and dispersed through the specific gravity of the soil. Foreign matter that falls to the plate (20) and has a small specific gravity rises toward the foreign matter outlet (13).

Soil (including soil with foreign substances attached) falls on the upper surface of the rotary dispersion plate 20 without being affected by the vortex, and is moved to the liner 14 by the rotation of the rotary dispersion plate 20 and the rotation of the scattering guide blades 22. , and foreign matter falls from the soil due to physical impact when it collides with the rotating dispersion plate 20 and the liner 14.

3. Secondary screening.

The soil is not affected by the eddy current, so it falls to the bottom through the gap between the rotating dispersion plate 20 and the liner 14 and is discharged through the soil discharge port 12.

On the other hand, since the foreign matter has only its own specific gravity at the moment it falls from the soil, it is affected by the vortex, rises into the inside of the vortex rotor 30, and is then discharged through the foreign matter outlet 13.

Separated soil and foreign matter are recovered separately through a conveyor belt or recovery pipe.

Figure 5 shows an airflow induction pipe 40 for using the airflow generated by the vortex rotating body 30 for primary dispersion by the rotating dispersion plate 20.

The airflow induction pipe 40 is connected so that both sides in the longitudinal direction communicate with the inside of the case 10, and directs the airflow by the vortex rotor 30 to the rotary distribution plate 20 without forming a separate fan. It is supplied to the bottom to help foreign substances fall from the soil and help them disperse.

The air flow induction pipe 40 is equipped with an opening/closing (opening degree adjustment possible) valve so that it can be used as needed.

delete

In addition, the air flow induction pipe 40 may include a vane 41 that guides the air flow inside the case 10 to the inlet end in order to smoothly introduce air flow at the inlet end.

According to the airflow induction pipe 40, some of the airflow directed upward due to the rotational force of the vortex rotating body 30 flows into the airflow induction pipe 40 and flows along the airflow induction pipe 40 before reaching the case 10. It is discharged inside.

The discharge location of the airflow is the bottom of the rotating dispersion plate 20, and foreign substances flying from this part rise with the help of the airflow and are discharged as they rise through the vortex caused by the rotation of the vortex rotor 30.

In addition, as a technology using the airflow induction pipe 40, it is also possible to connect the rotating dispersion plate 20 with the airflow induction pipe 40 to discharge an airflow that scatters soil and foreign substances from the rotating dispersion plate 20. do.

An airflow discharge hole 24 is formed inside the rotating dispersion plate 20. The inlet portion of the airflow discharge hole 24 is formed at the center and is connected to the discharge end of the airflow induction pipe 40 through a coupler, etc. A plurality of discharge units connected to the unit and arranged radially are formed to be disposed on the inclined unit.

If the airflow discharge hole 24 is smaller than the particle size of the soil or is larger than the particle size of the soil, a mesh structure net smaller than the particle size of the soil is applied.

Since the rotary dispersion plate 20 rotates in place, the inlet portion is formed at the center so that its rotation is not interfered with even if the fixed airflow induction pipe 40 is connected.

In this way, blowing air to the inclined portion of the rotary dispersion plate 20 can prevent foreign substances from adhering to the inclined portion and also helps the foreign substances to scatter, thereby improving the screening effect of foreign substances.
