る。2. Description of the Related Art For example, waste wood obtained by dismantling a general wooden house or the like is in a state where wood itself and other foreign materials such as nails and other iron materials and non-ferrous metals are mixed. Such waste wood needs to be crushed into small pieces and then separated into wood and foreign matter. Conventionally, a wind separation device has been used as one of the means. This device is well known and will not be described in detail here, but is simply as follows. In other words, a waste material such as the above-mentioned waste wood in which foreign substances are mixed is transported in the pipe duct by air pressure. At the end of the pipe duct, a T-shaped outlet duct is connected sideways. The sent air is divided into wood powder and foreign matter in the outlet duct and blows up and down, respectively. That is, at this time, wood powder or the like having a low specific gravity is discharged from an upward outlet, and foreign matters such as metal fittings having a high specific gravity are discharged from a downward outlet. Another type of sorter uses a cyclone-type centrifugal force. This sorter applies a centrifugal force to a pulverized waste wood by applying a rotating flow, and uses the difference in the centrifugal force to sort, for example, wood powder and foreign matter.

As described above, in addition to wood powders and the like, foreign materials such as iron powders and non-ferrous metal powders based on metal fittings and the like, as well as abrasion powders of the transfer line are included. Such a metal powder or the like naturally has a smaller mass when the particle size is smaller. For this reason, it has been practically difficult to effectively sort foreign matter from waste wood with the above-described conventional apparatus including a T-shaped pipe utilizing gravity difference and a cyclone type apparatus utilizing centrifugal force. That is, foreign substances such as metal powder could not be effectively removed from wood powder and the like.

That is, the raw material (object to be separated) 2A which flows out of the coarse crusher 3 and flows rightward in the drawing through the sorting pipe 4 is divided into wood and iron powder and the like (foreign matter) which are arranged outside the material. It flows to the right in a state of being sorted by the magnetic field from the machine 10. That is, when the coarsely crushed material 2 </ b> A moves inside the pipe duct 4, the wood powder and the foreign matter (such as iron powder) advance while the powder and the particles move individually and randomly. In this respect, the state is significantly different from the case of so-called conveyor conveyance. As described above, the inventor of the present invention has focused on the fact that the coarsely crushed material 2A travels in the pipe duct 4 by randomly operating particles and the like as described above, and has accomplished the present invention. It is. That is, the basic concept of the present invention is as follows. That is, since the wood powder and the foreign matter powder are mixed but separate, a magnetic field is applied from below the pipe duct 4. Thereby, the iron powder and the like are attracted downward in the pipe duct 4. In addition, regarding non-ferrous metal powder, when passing through a magnetic field, an eddy current is generated, and the flow velocity is braked. As a result, the pipe duct 4 is apparently suctioned downward. In this way, the coarsely crushed material 2A is
-1 is separated upward into coarse wood flour 2A-2. From this state, the two are separated.

る。The transport pipe 4 comprises a substantially horizontal transport pipe main body 4A and a T-shaped pipe 4B connected thereto. Thus, a sorting machine 10 for generating a strong magnetic field is installed below the outside of the transport pipe 4. That is, a belt 10B is wound around a pair of pulleys 10A, 10A outside the transport pipe 4, and permanent magnets 10C, 10C,... Are attached to the belt 10B at predetermined intervals to form a magnet row. One pulley 10A is slowly rotated by the motor 10D. Thereby, the magnet 1
The rows of 0C and 10C are also provided with coarse crushed material 2
Drive slowly according to the flow of A. As a result, when the raw material 2A flows through the transport pipe 4, the foreign matter (such as metal fittings) 2A-1 is positioned on the lower side and the coarse wood powder 2A-2 is positioned on the upper side.
The state is divided into two layers. Eventually, the transfer pipe 4 is divided into two at the end. That is, at the end, the suction port 4a
Air is sucked upward from above. Therefore, raw material 2
A coarse wood powder 2A-2 flows upward, but foreign matter 2A-1
Was originally separated into lower layers, so this pipe 1
1 falls from the gate 4b below, and foreign matter collection is performed. This foreign material must be removed regularly. The coarse wood powder 2A-2 flowing upward reaches the cyclone 7 together with the air, and is separated into air and coarse wood powder. As described briefly above, the air reaches the floor 6 after fine dust such as dust is removed by the back filter 8, and is radiated to the atmosphere. On the other hand, the coarse wood powder 2A-2 is further finely pulverized by the pulverizer
4 fall on. This wood pulverized material 15 is pressed by a press machine 16 at the next stage to obtain a continuous product (plate material).

In this case, the air may flow by air pressure in a state of being separated into upper and lower parts. Examples of these are shown in FIGS.

One end is connected to a cyclone separator 40, and an annular magnet 41 is arranged outside the cyclone separator 40, and the magnet 41 is rotated around an axis. Thus, the foreign matter is rotated near the inner surface of the separator 40 and dropped downward, and only the coarsely crushed wood is rotated near the center and flows upward together with air.

Then, it is further transported in this state. For this reason, by bifurcating up and down at the end, foreign matter (metal fittings, etc.) separated in advance can be dropped downward by weight, and lighter coarse wood powder can flow out together with air upward. it can. That is, it can be surely separated into wood powder and foreign matter.

Then, it sinks downward in the pipe (a forked part of the end). However, fine iron powder and the like are carried upward together with the product by the flow of air. However, according to the present invention, iron (including iron powder) is forcibly attracted and separated by a permanent magnet band or the like provided below the pipe. The iron attracted to the permanent magnet band moves with the rotation of the permanent magnet band, and falls due to the disappearance of the magnetic force at the end of the forked portion. Thus, it is continuously discharged out of the system.
