2. Description of the Related Art Various wind power sorters have been proposed as a sorter, and Japanese Patent Laid-Open No. 7-1455 discloses a sorter for separating urethane, plate and plastic.

[0003]

A crushed piece in which a material to be separated is a heavy material such as a metal, an intermediate heavy material such as a plate-shaped plastic, and a light material such as a lumped foam insulation (hereinafter referred to as urethane) Then, consider a case where only the foam insulation material is separated from the crushed pieces at the point A and transported to the point B as shown in FIG.
First, as a case 1 (FIG. 2 (A)), it may be considered that the sorting machine is a wind power sorting machine installed at the point A, and the duct of the wind power sorting machine is extended to the point B for transportation. However, since the crushed pieces are usually discharged from the lower part of the crusher, a vertical transportation means such as a bucket elevator is required up to the inlet of the wind sorter. That is, a transportation means other than a sorting machine is required.

Next, as Case 2 (FIG. 2 (B)), a wind power sorter is installed at the point B, and the transportation means from the point A to the wind force sorter is considered by pneumatic transportation. At this time, an air blower for air transportation is required, and if it is assumed that one air blower serves as both the air blower for air transport and the air blower for the wind force sorter, the wind blower sorter will be separated for the following reasons. Performance decreases.

That is, in the wind power sorter, the wind flow passage and the inlet are usually sealed by a rotary valve or the like so as not to affect the wind flow passage. The behavior of the wind near the inlet differs from the behavior of the original wind sorter. In addition, since the wind speed of air transportation and the wind speed of wind separation are completely different, it is difficult to match the inside and outside of the wind passage. For the above reasons, it is difficult to combine the wind power sorter and the air transport means for air transportation in Case 2 and to expect the performance of the original wind power sorter. In this case, a blower means is required in addition to the wind power sorter. .

It is an object of the present invention to provide a sorting / transporting device which has a single blowing means and which is capable of sorting and transporting sorted materials.

[0007]

[Means for Solving the Problems] A suction port having a grate, a belt conveyor having a plurality of scraping blades for scraping off the plastic and the like adhering to the grate fixed on a belt of a belt conveyor, and a suctioned foam insulation material. This is achieved by using a sorting / transporting device configured by an air transport pipe for air transport and a wind force sorter having a blower that also serves as the suction means for air transport and the blower means for the wind force sorter.

The material to be separated supplied to the belt conveyor is
Due to the wind speed at the suction port, heavy objects are separated without being sucked. Also, although the plastic seems to be sucked in, it is caught in the grate and is scraped off by the scraping blades and collected together with the metal. Therefore, only lightweight urethane is sorted.

DETAILED DESCRIPTION OF THE INVENTION

Embodiment 1 FIGS. 1 and 3 show an embodiment of the present invention. FIG. 3 is a cross section taken along the line AA of FIG. Pneumatic transportation is the suction port 1,
It is composed of a pipe 2 and a blower 4 installed in the dust collector 3.
The suction port 1 is composed of a casing of 5 and a grate of 6. Here, the great 6 is obtained by arranging the strips (6) of FIG. 1 at equal intervals as shown in FIG. 3 and fixing them to the support 7. Reference numeral 8 denotes a belt conveyer for supplying crushed pieces which are the separated substances to the suction port, and this conveyor has a role of scraping the plate-shaped plastic 9 caught on the grate 6 together with the supply of the separated substances. Therefore, L-shaped scraping blades 11 are fixed to the belt 10 of the belt conveyor at equal intervals via the contact plate 12. Further, in order to prevent the crushed pieces from spilling from both sides of the belt, the guide 13 of FIG. 3 is fixed to the frame 14 of the belt conveyor (the guide and the like are omitted in FIG. 1). The distance between the suction port and the belt conveyor is adjusted so that metal cannot be sucked up, while urethane can be sucked up almost entirely. When the object to be separated is supplied to the belt conveyor, the heavy object such as metal is not sucked even at the wind velocity of the suction port and is recovered as it is in the recovery unit 15. The plate-shaped plastic 9 is divided into one that is sucked up by the suction port and one that is not sucked up and is collected by the collecting unit 15. The sucked up plastic is
Most are caught in Great 6. On the other hand, the lightweight urethane 16 is sucked into the suction port. If the plastic stuck on the Great is left as it is, the suction port will become clogged.
Since it is always scraped off by, it falls on the belt again and is collected in the collecting unit 15. On the other hand, the sucked urethane enters the dust collector having the filter 17 and the rotary valve 18
It is recovered to the recovery unit 19 via the.

One of the applications of this sorting and transportation device is the sorting of crushed pieces of waste refrigerators for urethane, plastic and metal.

Then, as a result of the experiments conducted by the inventors using the crushed pieces of the waste refrigerator, when the interval of the grates is 50 mm, a part of the urethane is scratched and scraped off by the grates, so that the recovery rate of the urethane is lowered, and conversely, it is the grates. Is 1
If it is more than 00 mm, the plastic is sucked and the mixing rate of the plastic increases. Therefore, it became clear that the proper interval is 50 to 100 mm.

Example 2 In the apparatus of Example 1, most of metal and plate-shaped plastic can be separated, and the plastic mixed in the separated urethane is Great 6
Only the small plastic that passed through. However, if further sorting performance is required, a more complete sorted product can be obtained by combining the wind power sorter with the first embodiment. Less than,
This will be described with reference to FIG. The present embodiment is characterized in that the blower of the dust collector serves both as the air blower for the wind force sorter and the air blower for air transportation.

In FIG. 4, the air sucked from the suction port 1 passes through the air transport pipe 2 and the wind tunnel of the wind force sorter 20 and exits to the dust collector 3. The wind velocity in the wind tunnel of the wind power sorter 20 sharply decreases at the input port 21 of the wind force sorter because the cross section of the wind tunnel is larger than the cross section of the air transport pipe. Then, a valve provided at the air intake 22 finely adjusts the wind speed to the optimum wind speed for the wind power sorter. The operation will be described below. The crushed pieces discharged from the discharge port 23 of the crusher are placed on the belt conveyor of the first embodiment via the hopper 24, and the suction port separates metal and plastic. Since the function here is the same as that of the first embodiment, it is omitted. Part of the sucked urethane and plastic enters the wind force sorter through the inlet 21. Here, the light urethane is blown into the dust collector as it is , and the plastic is collected through the rotary valve to the recovery unit 1.
Recovered to 5.

In the case of this embodiment, the small pieces of plastic sucked by the suction port are also sorted by the wind force sorter, so that sorting with high precision becomes possible.
