[0002]

According to a conventional crusher for crushing waste plastics, which will be described below, slender objects such as rod-shaped metals, wires, strings, nets and thermosetting plastics mixed in the waste plastics are used. Alternatively, the foreign matter of the soft material is often entangled in the crushing blade, caught in other waste plastics, or these foreign matter escapes from the blade and is discharged to the subsequent process without being crushed. When the foreign matter is sent to the post-process side in this way, in an extruder that presses and heats the waste plastic in the subsequent process to extrude the waste plastic, if the foreign matter enters the die, it enters the die. The foreign matter in this state is caught in the die by the rotation of the screw so that the portion exposed to the die inlet side is moved in the lateral direction of the die. Subsequent foreign matter to such foreign matter is more likely to stay in the die, and stays there. As a result, extrusion cannot be performed from the extruder, and the extruder stops due to overload.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

(Crushing and Sorting System) FIG. 1 is a flow sheet showing the crushing and sorting system of the present invention.

The raw material W carried by the carrying means 1 is a waste plastic containing various kinds of waste plastics, such as wires, elongated metal pieces as metals, strings, textiles, chips, etc. as fibers. As the kind of resin, a thermoplastic resin,
It contains foreign substances such as thermosetting resins and cullets, as well as steel and aluminum pieces. This raw material W is brought in by the conveying means 1 and guided from the input hopper 2a to the bag breaking machine 2b to break the bag and release the waste plastics contained therein. . The released waste plastics are sent to the vibrating screen 4 by the conveyor 3, the cullet 5 is taken out under the net on the vibrating screen 4, and the rest of the net objects are the first.
It is sent to the next magnetic separator 6 and the steel scrap 7 in the waste plastics is taken out. Aluminum 9 is extracted from the waste plastics discharged from the primary magnetic separator 6 by the aluminum separator 8. The waste plastics from which the aluminum 9 has been removed by the aluminum sorter 8 are put into the crusher 11. The crusher 11 is an impact shearing crusher or the like, and waste plastics are finely crushed. When the waste plastics discharged from the crusher 11 pass through the secondary magnetic separator 12, the steel scraps 13 in the waste plastics are removed.

The waste plastics that have passed through the secondary magnetic separator 12 in this manner are removed over the steel scraps 7 and 13 twice in the primary magnetic separator 6 and the secondary magnetic separator 12. However, for example, iron wires or elongated iron pieces pass through the crusher 11 without being completely shredded. The slender aluminum also passes without being crushed by the crusher 11. Then, even in the primary and secondary magnetic separators 6 and 12, the finely chopped pieces are magnetically separated, but elongated iron pieces, wires and the like pass through. Similarly, when the crusher 11 has a shearing blade or a hammer type, some of the thread waste, the woven fabric, the fiber waste, etc. pass without being cut, and there is no sorting method. It is mixed in the waste plastics leaving machine 12.

The waste plastics that have passed through the secondary magnetic separator 12 are put into a vibrating mill 14, where slender metal, wire and the like mixed with the waste plastics, strings, woven fabrics, shavings, and thermosetting. Foreign matter such as resin is crushed. At the same time, the waste plastics are also finely crushed. These crushed waste plastics and foreign substances are collected by the wind power sorter 1
5, the wind force classifier 15 performs classification by wind force, cullets having a relatively high specific gravity, metal particles crushed by the vibration mill 14 into metal particles, sand particles, etc. are discharged from the discharge port 15a, and are relatively discharged. Waste plastics and soft materials having a low specific gravity and dust such as fine particles of metal, glass, etc. which are heavy but have a high specific gravity are sent out by wind force from the outlet 15b and are sent by air to the cyclone 17 in the air transport pipe 16. Cyclone 17
Is divided into sediment and suspended matter, and the relatively light soft matter and dust are sucked by the exhaust blower 21 through the intake pipe 18 and the bag filter 19, and the remaining waste plastic is quantified from the outlet 17a at the bottom of the cyclone 17. The waste plastic is discharged to the supply conveyor 22a and sent to the waste plastic volume reduction and solidification machine 22 by the conveyor 22a. The waste plastics solidified by the waste plastics volume solidifying machine 22 and then discharged and discharged are dropped onto the distribution conveyor 24 by the conveyor 23. The distribution conveyor 24 is a belt conveyor and is arranged in a horizontal direction. The belt feeding direction on the upper surface is controlled to be forward and reverse directions, and is distributed to the two bunkers 25A and 25B. The waste plastics solidified material stored in the bunker 25A or 25B is carried out to the truck 26 that has entered below the two bunker 25A or 25B.

As the auxiliary equipment in the above, the first bag-breaking machine 2b, the vibrating screen 4, and the first bag-breaking machine 2b vibrates because dust is generated by the bag-breaking, material crushing and vibration in the crushing machine 11. Dust suction pipes 2b1, 4c, 11c are led out from the screen 4 and the crusher 11, and these are collected in the collective dust suction pipe 27, and the end of the collective dust suction pipe 27 is connected to the air transport pipe 16 for communication. .

Since the inside of the air transport pipe 16 is made to have a negative pressure by the exhaust blower 21 sucking the air in the cyclone 17, the bag breaking machine 2b, the vibrating screen 4,
The dust generated in the crusher 11 is the dust suction pipes 2b1 and 4 respectively.
After passing through c and 11c, they are gathered in the aggregate dust suction pipe 27, merged with the waste plastics containing dust sent from the wind power sorter 15 in the air transport pipe 16, and sent to the cyclone 17.

The odor suction pipe 28 having the hood 28a at one end, which is disposed toward the outlet of the waste plasticizer / solidifier 22, and the other ends of the odor suction pipes 25A1 and 25B1 whose ends are open to the bunkers 25A and 25B, respectively. Is an odor suction collecting pipe 29
Is connected to the suction port of the exhaust blower 32 through a deodorizer 31 having a built-in activated carbon filter or the like installed in the odor suction collecting pipe 29, and by operating the exhaust blower 32, the waste plastic is reduced in volume and solidified. Organic matter mixed with waste plastics at the exit of machine 22, bunker 25
Air containing odors is sucked from the organic substances in the waste plastics in A and 25B by the odor suction pipes 25A1, 25B1 and 28, the air is joined to the odor suction collecting pipe 29, and the odor is removed by the deodorizer 31. Then, the exhaust blower 32 releases odorless air into the atmosphere.

(Method for crushing foreign substances) As described above, many foreign substances such as wire or slender metal, strings, woven fabrics, shavings and thermosetting resin are not crushed by the crusher 11 and crushed. The foreign substances still remain in the waste plastics of the processed product discharged from the machine 11. When these foreign substances are sheared by a shearing blade or hit by a hammer, they pass through the shearing blades or pass through a gap that is not hit by the hammer in terms of time, so a crusher of the same type is further installed in the crusher 11. If installed, the number of crushers is not allowed to increase, and yet some of the foreign matter in the waste plastics will pass through the crusher.

In the present invention, a large number of solid crushing media and waste plastics containing the above-mentioned foreign matter are contained in a container, and the container is vibrated so that the crushing medium acts on the foreign matter many times to separate the waste plastics. Alternatively, the foreign matter is cut into small pieces.

The vibrating mill 14 is specifically used to enable continuous production using this method.

An external view of the vibrating mill 14 used in this example is shown in FIGS.

A mill body 14c having a hollow cylindrical shape and having a raw material inlet 14a at one end in the longitudinal direction and a treated product outlet 14b at the other end in the longitudinal direction is a mill main body 14c, which is located at each of two longitudinal positions. It has a bearing bracket 14d, and the inner ring of the rolling bearing 14e having the outer ring fitted to the bearing bracket 14d is fitted to the drive shaft 14f. Bearing bracket 1
4d is connected to a machine frame 14h fixed by a coil spring 14g. In this connection method, for example, a through bolt (not shown) is inserted and held through the bearing bracket 14d, the center of the coil spring 14g, and the machine frame 14h to hold the mill body 14c.

The drive shaft 14f is connected to the motor shaft of the motor 14j via a universal shaft joint (not shown) in the shaft joint case 14i. An unbalanced weight 14q for rotation is fixed to the drive shaft 14f.

A large number of crushing media are housed in the mill body 14c. The internal structure of the mill body 14c differs depending on whether the crushing medium is a lump or a long rod. When the crushing medium has a long rod shape, as shown in FIG. 4, the mill body 14c is a hollow cylindrical trough 14p, and the inside is one space. If the crushing medium is lump-shaped,
As shown in FIG. 14, a sieve 14n is formed so as to form a space 14k communicating with the raw material inlet 14a and a space 14m communicating with the outlet 14b.
The cylindrical trough 14p of the mill body 14c is partitioned by. This sieve 14n is a flat plate which is slightly horizontal with the discharge port 14b side lowered, and this flat plate is made of a perforated plate. The pore diameter of this perforated plate is smaller than the diameter of the block-like crushing medium described later, and the crushing medium cannot pass through it, but the crushed foreign substances and waste plastics can pass through.

The rod-shaped crushing medium has a large number of rods 33 of round cross section having a length close to the entire length of the trough 14p, as shown in FIG. This rod 33
Is selected so as to occupy 1/2 to 1/3 of the sectional area of the trough 14p. Iron material is selected as the material, but quenched steel material having high hardness is suitable. This is because the bending action reduces the crushing action.

As the crushing medium, for example, a steel ball 34 (see FIG. 8) is used as the crushing medium, and the steel ball 34 is placed in the space 14k.
To accommodate.

The operation of the above configuration will be described.

(When the crushing medium is a rod) In the vibrating mill 14 in which the raw material is not charged and is stopped in the state of FIG. 4, when the motor 14j is energized, the drive shaft 14f is passed through a universal shaft coupling (not shown). Rotates with the unbalanced weight 14q and periodically applies a force to the trough 14p via the bearing 14e and the bearing bracket 14d. Therefore, the trough 14p in which the bracket 14d part is supported by the coil spring 14g is indicated by the chain double-dashed line in FIG. It vibrates as shown and the rod 33 springs within the trough 14p as shown in FIG. The vibration of the trough 14p is circular vibration (a point on the trough 14p draws a circle on a plane perpendicular to the trough 14p).

As shown in FIG. 6, the raw material W which has passed through the secondary magnetic separator 12 and fed from the raw material feeding port 14a enters the gap between the spring rods 33, and when the rods 33 collide with each other, the raw material W In particular, the foreign matter is easily crushed between the rods 33 and is therefore crushed together with the waste plastics. The raw material W thus charged is discharged through the trough 14p into the discharge port 14b.
Then, the powder is pulverized and discharged from the discharge port 14b as shown in FIG.

(When the crushing medium is steel balls) In the vibrating mill 14 stopped in the state of FIG.
The mode of movement of the trough 14p when the motor 14j is energized is the same as in FIG.

As shown in FIG. 9, when the raw material W passed through the secondary magnetic separator 12 is fed from the raw material feeding port 14a,
As shown in FIG. 10 (A), if the steel balls 34 bounce in the direction of the arrow shown in the figure, a string or tape W is placed between the steel balls 34.
1 enters. Then, as shown in FIG.
4 collides with each other in the direction of the arrow and acts on the string or tape W1 sandwiched between them to secure the string or tape W1.
Cut as shown at 0 (C). Of course, the foreign matter other than the string or the tape W1 and the waste plastics are also sandwiched between the steel balls 34 which collide with each other and crushed.

Another example of the fracturing medium used above is shown in FIG.
It is shown in FIG. FIG. 11 (a) is a stamped and forged product made of steel, in which a number of tapered projections 34b are provided on the peripheral surface of the sphere 34a outward in the normal direction of the spherical surface. FIG. 11 (b) is a stamped and cast product made of steel, in which projections 34c having hemispherical tips are provided in six directions outward from the center sphere. FIG.
In (c), a large number of chevron-shaped projections 33a are provided on the outer circumference of the rod 33. FIG. 11D shows a rod 33 provided with axially extending projections 33 b on the peripheral surface thereof. FIG. 11 (e)
Makes the body 33c of the rod 33 a round bar, and spirally winds the wire rod 33d around the outer circumference of the round bar.
It is welded to 3c. In FIG. 11 (f), the rod body 33c is a round bar, and a strip steel 33e having a knurl on one side is spirally wound and welded on the outer circumference of the round bar with the knurled edge on the outer diameter side.

In the crushing medium of FIG. 11 (a), the projection 34b sharply hits the raw material, so that the cloth is torn and crushed. In the crushing medium of FIG. 11B, since the projection 34c presses the raw material, the projected area of the projection 34c with respect to the string or tape W1 in the normal direction is large, so that the probability of the action of sandwiching the string or tape W1 is high. When the crushing medium as shown in FIG. 11 (c) is used, the protrusions 33a act strongly on the cloth like the crushing medium of FIG. 11 (a). In the crushing medium shown in FIG. 11 (d), the rod 33 moves with its rotational surface centering on the axial center of the rod 33 or a center parallel to the axial center of the rod 33 so as to move in the circumferential direction. The rods 33 rub each other in the circumferential direction to crush the sandwiched raw material. According to the rod of FIG. 11 (e), since the wire 33d often enters the valley of the thread between the wire 33d of the mating rod 33, the wire or the elongated metal plate is cut by applying repeated bending force to the wire or the elongated metal plate. It According to the rod of FIG. 11 (f), in addition to the action of the rod of FIG. 11 (e), a string, cloth, shavings, etc. are cut by the notched band steel 33e.

The crushing medium as described above is selected to be compatible with the foreign substances mixed in the raw material to be treated.

(Wind sorting machine) In the wind sorting machine 15, as shown in FIG. 1, the raw material charging port 15c is the discharge port 14 of the vibration mill 14.
Directly below b. A raw material inlet 15c is provided at the upper portion, a lower outlet 15a is provided, and an outlet 15b is provided downstream of an air passage 15d that crosses the upper and lower raw material inlets 15c and the outlet 15a. On the upstream side, there is a closed casing 15f provided with an air blowing port 15e, and further there is a blower 15g for blowing outside air into the casing 15f from the air blowing port 15e.

The capacity of the blower 15g is significantly smaller than that of the exhaust blower 21 so as not to significantly affect the depressurized state generated by the exhaust blower 21 at the confluence point a of the collective dust suction pipe 27 and the air transport pipe 16. It is a thing.

When the blower 15g is energized, the air inlet 15
Air is blown into the casing 15f from e, and an air flow is generated in the air passage 15d. Discharge port 1 of vibration mill 14
The raw material that has entered casing 15f from 4b through raw material inlet 15c falls and tries to pass downward through air passage 15d. However, the light waste plastic, small fibers, dust, etc. in the raw material that has entered the area of the air passage 15d will be at the outlet 1
It is sent out from 5b to the air transport pipe 16. The cullets, small-sized metals, sand grains, etc. in the raw material can be removed through the air passage 15d.
Passing downward through the air flow through the casing 15f
On the bottom plate and goes toward the discharge port 15a.
