The crushing section 1 is provided on one side (the left side in FIG. 1) of a main body case 9 which is set on a supporting stand 7 and surrounds the entire peripheral surface.
1, a discharge port 13 is provided on the other side (bottom surface), and a rotary crushed body 1 is provided in the main body case 9 of the crushing section 1.
5 are provided.

As shown in FIG. 2, a rotor 19 is fixed to a rotating shaft 17 to which a high-speed rotating power is applied in a direction indicated by an arrow from a driving unit (not shown). 21 are provided.

When the hammer 21 rotates at a high speed, the input port 1
It functions to crush small pieces by repeatedly crushing the waste material sent from 1. A first repulsion plate 23 and a second repulsion plate 25 are respectively arranged in regions where the waste material sent from the charging port 11 is crushed by the hammer 21, and the device is designed so that crushed pieces do not directly hit the inner wall of the main body case 9. Have been.

The inlet 11 of the crushing section 1 is provided with dust preventing means 27 for preventing dust from jumping out and crushing piece preventing means 29 for preventing crushed pieces from jumping out.

The dust prevention means 27 is provided with an injection nozzle 31 along the input port 11, and the injection nozzle 31 is connected to and communicates with a mist generator (not shown), and jets high-speed mist with coarse particles. As a result, a mist-like film is formed so that the inlet 11 is blocked, and particles adhere to the dust to prevent the dust from rising.

The crushed piece preventing means 29 is formed by arranging a plurality of chains 33 so as to close the input port 11 and suspending and supporting the upper end of the chain 33, and forming a waste material by setting the lower end to a free end. There is no effect on the input of refuse.

The bucket elevator 3 is provided with an inlet 37 below the elevator body 35 whose entire peripheral surface is surrounded, an outlet 39 above, and a bucket 41 inside.

The intake port 37 of the bucket elevator 3 is connected to the discharge port 13 of the crushing section 1 via a closed passage 43. The passage 43 connecting the inlet 37 and the outlet 13 is formed by ducts connected to the inlet 37 and the outlet 13, respectively.

As shown in FIG. 3, the bucket 41 has a bucket body 51 attached at predetermined intervals to a chain 49 wound around a driving sprocket 45 and a driven sprocket 47 endlessly. It is set to a low speed operation of 10 to 10 rotations. And the bucket body 5
1 has a second sub-bucket portion 53 that receives the crushed material falling from the upper bucket body 51 and then drops toward the outlet 39 after receiving the crushed material.

The sub-bucket section 53 is set so that, in the area of the outlet 39, a discharge completion posture is obtained from the discharge posture following the discharge completion posture of the bucket body 51.

The sieving unit 5 is called a rotary screen, and is supported by a machine base 55 and is provided with a take-out port 3 of the bucket elevator 3 through a closed passage 57.

In addition, below the opened sieving part 5,
A conveyor 63 is provided for collecting the sieved crushed materials at a predetermined location.

Next, the operation will be described. For example, asphalt waste material is fed into the crushing section 1 from the input port 11 by a conveying means such as the belt conveyor 65. The sent waste material is crushed small by the action of the rotary crushing body 15. The crushed pieces that are crushed during this crushing are prevented by the crushed piece prevention means 29 and do not jump out. Further, the generated dust is prevented by the mist-like film by the dust prevention means 27, and the water droplets adhere to the dust and the rising is prevented. On the other hand, the crushing noise is suppressed to be small by the main body case 9 surrounding the whole.

Next, the crushed material crushed in the crushing unit 1 is sent upward by the bucket 41 of the bucket elevator 3 and sent out to the sieving unit 5. This bucket 41
As a result, the air is not agitated, the generation of dust is suppressed, and no loud conveying noise is generated. In this case, the crushed material in the bucket body 51 falls naturally without receiving the driving energy due to the low speed, but at this time, after being received by the lower sub-bucket portion 53, the crushed material is sent to the outlet 39. Become. Therefore, there is no influence on the removal of the crushed material by the low-speed operation. In addition, rising of the dust in the transporting step is suppressed by water droplets attached in the crushing step.

On the other hand, the crushed material sent to the sieving section 5 is sieved according to various sizes. At the time of this sieving, since the water droplets for suppressing the rising are small in particle size, the dust does not become a paste, but passes without closing the mesh, and does not hinder the selection of the crushed material. In addition, the generation of sorting noise, dust and the like can be suppressed to a small level.

[0025]

As described above, according to the waste material treatment apparatus of the present invention, the feed speed of the bucket elevator can be reduced, and the dust and noise can be reduced in combination with the condition that the entire circumference is surrounded. Can be reduced. In addition, the bucket elevator enables a layout in which the crushing unit and the sieving unit are close to each other, and has an advantage that the installation space of the entire apparatus can be reduced.
