(Not shown).

  The fixed crushing plates 31 to 33, the guide plate 34, the base plate 35, and the horizontal plate 36 are accurately formed by laser cutting in the present embodiment, whereby the through hole 30a and the crushing projections 31a to 33a are formed. The projecting pieces 31b to 33b and the engaging hole 34a, and the cut grooves 31c to 33c and the horizontal plate 36 are fitted or engaged with each other with high accuracy without rattling.

  Each of the fixed crushing plates 31 to 33 is configured as one unit together with the guide plate 34, the base plate 35, and the horizontal plate 36 that connect and hold them, and the base plate 35 is welded onto the bottom 2a of the melting tank 2. It attaches to the plate-shaped base 37 integrally provided by detachable by fixing with the volt | bolt 38 grade | etc.,.

Further, each of the fixed crushing plates 31 to 33 has openings 31d to 33d as shown in FIGS. 4 and 8 , and a heater 40 for warming a solvent such as limonene is provided so as to penetrate the openings. It has been. The heater 40 is provided with a pipe line 41 that detours in the front-rear direction in FIG. 4 and circulates hot water from a boiler or the like omitted in the figure into the pipe line 41.

  Further, an upper collection container 45 that collects suspended matters such as dust floating in the solvent is detachably provided on the upper portions of the fixed crushing plates 31 to 33. In the illustrated example, the collection container 45 has a structure in which nets 45b are stretched on the front, rear, left, right, and bottom surfaces excluding the top surface of a frame body 45a having an inverted trapezoidal cross section, and handles 45c are provided at both longitudinal ends of the frame body 45a. Is provided.

  When each impeller 10 rotates along the guide plate 34, a region surrounded by the outer blade plate 12, the pair of side plates 11 and 11, and the guide plate 34 is shown in FIG. As shown in FIG. 10, a concave portion Q for solvent pumping having a substantially V-shaped cross section is formed, and the solvent S accumulated in the pumping concave portion Q moves toward the upper recovery container 45 as the impeller 10 rotates. Thus, the solvent S flows into the container 45, whereby dust or the like in the solvent S is captured and collected by the collection container 45.

  In the above-described configuration, for example, when a synthetic resin waste such as used polystyrene is dissolved in an organic solvent such as limonene, the motor 6 is driven to operate the pump 4 and a new solvent is supplied to the supply pipe 5. Through the spray nozzle 3 and supplied into the dissolution tank 2. At that time, if the old solvent is attached to the impeller 10 or the collection container 7 or 45 in the previous dissolution process, the old solvent is washed away by providing the spray nozzle 3 on the upper part of the dissolution tank 2. be able to.

  When the solvent is supplied to the dissolution tank 2 to a predetermined initial level as described above, the waste W is charged into the dissolution tank 2 from the waste inlet (not shown) at the top of the main body frame 1. At that time, the impeller 10 is set so as to stop at a fixed position shown in FIG. 4, and this fixed position is a state where a space in the dissolution tank 2 above the impeller 10 is widely vacant, and the waste is the most. Many can be thrown in.

  When the waste is put into the dissolution tank 2, the opening / closing door (not shown) is closed and the motor 9 is driven to rotate the impeller 10, and the motor closes the opening / closing door. Sometimes it can be configured to drive automatically. In that case, for safety, it is preferable that the impeller 10 is configured to rotate several seconds after the door 2 is closed. However, this is not limited to the above as long as it is configured to automatically feed using a conveyor or the like and the safety is ensured by surrounding the slot with a fence or the like.

  When the impeller 10 rotates as described above, waste is sequentially pushed into the solvent by the impeller 12 and the movable crushing plate 13 of the impeller 10. At that time, waste adhering to the inner surface of the side plate of the dissolution tank 2 is sequentially scraped off at the tip of the sickle-shaped movable crushing plate 13, and waste that has not been scraped off at the tip is V-shaped of the movable crushing plate 13. It is pushed into the solvent by the mold notch recess 13d.

  The waste pushed into the solvent is sequentially cut by the movable crushing plate 13 and the fixed crushing plates 31 to 33 of the impeller 10, and is gradually crushed by repeating this. At this time, since the positions of the crushing plates 31 to 33 with respect to the impeller 10 are shifted in the rotational direction of the impeller 10 as described above, it is possible to prevent a large force from acting on the impeller 10 at one time. The load on the motor is reduced.

  Since the above-mentioned waste crushing operation is mainly performed in a solvent, the waste can be smoothly performed without flapping or splashing, and no static electricity is generated. In addition, the waste pushed into the solvent is gradually dissolved in the solvent, and the contact area with the solvent is increased by the above-mentioned crushing to promote dissolution.

  Further, as the impeller 10 rotates as described above, the waterfall dropping recess P formed by the side plates 11 and 11 and the blade plate 12 enters the solvent as shown in FIG. It is exposed above the surface and enters the solvent again. By repeating this, the solvent S accumulated in the recess P is sprinkled on the waste in a waterfall manner, and the solvent is stirred to increase the dissolution rate of the waste.

  Furthermore, by providing the heater 40 for heating the solvent, the solvent such as limonene can be efficiently warmed and the synthetic resin waste such as foamed polystyrene can be more efficiently dissolved. In addition, when the dissolution rate of expanded polystyrene is, for example, about 20 to 30% by weight, the viscosity of an organic solvent such as limonene becomes much higher than that of the new solution, so that it becomes difficult to dispose of the waste solution. The waste liquid falls smoothly. In addition, heat is not directly transferred to the organic solvent, but heat is transferred from both sides by the hot water type heat radiation, so that it is very safe and heat efficiency is good.

  As the impeller 10 rotates, the solvent pumping recess Q formed by the guide plate 34 and the pair of side plates 11 and 11 of the impeller 10 and the vane plate 12 moves upward along the guide plate 34. Then, the solvent S collected in the concave portion Q when it moves to the side of the upper recovery container 45 flows into the recovery container 45 and is filtered. By repeating this, dust and the like floating in the solvent S can be sequentially captured and recovered by the recovery container 45. The solvent that has permeated the recovery container 45 and has flowed downward passes through the lower surface side of the guide plate 34 and sequentially moves below the impeller 10, joins with the solvent in the vicinity thereof, and repeats circulation.

  In addition, when sand, pebbles or the like are introduced into the dissolution tank 2 together with the waste and mixed with the solvent, they gradually descend in the solvent and settle on the dissolution tank bottom 2a, and then the bottom along with the flow of the solvent. It moves toward the discharge passage 2b along the inclined surface 2a, and is collected in the lower collection container 7 provided in the passage 2b. The sand, garbage, etc. recovered in the lower recovery container 7 and the upper recovery container 45 can be taken out from the dissolution tank 2 together with the recovery container after the dissolution process, for example, and discarded. Further, if necessary, for example, if a permanent magnet or the like is installed in the recovery container, the bottom of the dissolution tank, or the like, metal foreign matter can be adsorbed.

  In the state where the impeller 10 is rotating, for example, when waste is caught between the impeller 10 and the inner surface of the side plate of the dissolution tank 2 and the motor 9 is stopped, the motor 9 is reversed. The waste can be removed by rotating it in the opposite direction. At that time, since the outer peripheral edge 13c of the movable crushing plate 13 of the impeller 10 is curved inward in the radial direction as it goes to the front side in the rotational direction as described above, the outer peripheral edge 13c when the impeller 10 is reversed. Tends to move away from the waste sandwiched between the inner surface of the dissolution tank, so that the reverse rotation can be performed smoothly. The same applies to the relationship between the impeller 10 and the guide plate 34. The clearance between the impeller 10 and the guide plate 34 decreases as it goes downstream in the rotational direction of the impeller 10 as described above. Since the clearance increases as it goes to the front side in the rotation direction, it can be reversed smoothly.

  In addition, when an overload is applied to the motor due to a waste trapped as described above, the motor may be automatically detected to stop the motor, and the motor is automatically reversed if necessary. It can also be configured to be. For example, when an overload is applied to the motor or the like for some reason, the rotation of the impeller is temporarily stopped, and then the reverse rotation is performed, for example, about 1/2 rotation, and then the normal operation is tried again. For example, if the overload is not eliminated even if this is performed about three times, it may be automatically stopped. In the present embodiment, most of the overload is eliminated by the above operation.

  The synthetic resin waste charged into the dissolution tank 2 as described above is sequentially dissolved by a solvent, and when a predetermined amount of waste is dissolved, the rotation of the impeller 10 is stopped, or an alarm or the like is issued. Encourage exchange. As the means, for example, the amount of the solvent whose volume is increased by dissolving the waste is detected by a glass tube type liquid level sensor or the like installed outside the dissolution tank, and the impeller drive motor is stopped based on the detection. Notify the solvent exchange. Further, the upper limit allowable level of the solvent can be written on the glass tube, and when the liquid level of the solvent reaches that level, it is possible to promote the solvent exchange or the like, or to replace it automatically.

  Next, when the impeller 10 is stopped, the solvent in the dissolution tank 2 in which the waste has been dissolved is recovered from the discharge pipe 8 connected to the bottom of the dissolution tank 2 into the recovery tank omitted in the figure by the pump 4. . At that time, dust and the like that could not be captured by the collection containers 7 and 45 can be collected by providing a dust filter or the like between the discharge pipe 8 and the collection tank. In addition, the dust trapped in the collection containers 7 and 45 can be easily removed by taking out the containers from the waste input port or the maintenance opening not shown in the figure, and then a new solvent. Can be cleaned when spraying into the dissolution tank. At that time, the dirt in the pump generated at the time of discharging can be removed.

  When the synthetic resin waste is sequentially crushed by the movable crushing plate 13 and the fixed crushing plates 31 to 33 of the impeller 10 and dissolved in the solvent as described above, the cans, bottles, wood chips, etc. When a hard foreign substance enters the dissolution tank 2 and the impeller 10 or the cylinder shaft 15 is deformed or damaged, it can be repaired or replaced as follows.

  For example, when it is necessary to repair or replace the movable crushing plate 13 of the impeller 10, the movable crushing plate 13 is taken out by cutting and removing the rivet connecting the movable crushing plate 13 and the side plate 11 with a tool or the like. What is necessary is just to fix or replace | exchange and to fix to the side plate 11 with a rivet newly. At that time, the distance between the adjacent impellers 10 and 10 and the distance between the outermost impeller 10 and the inner surface of the dissolution tank are formed so that a wrench caulking spanner or the like can be sufficiently inserted. be able to.

  When it is necessary to take out the impeller 10 together with the cylinder shaft 15 from the dissolution tank 2, the connection between the cylinder shaft 15 and the support shafts 16 provided at both ends thereof may be released. 18 is pulled out, the connecting pin 18 is pulled out, and the support shaft 16 connected to the output shaft 9a of the motor 9 is connected to the output shaft 9a by the coupling material 25 for connection. To release. If both the support shafts 16 are moved into the cylindrical shaft 15, the rotary blade 10 including the cylindrical shaft 15 and the support shaft 16 can be taken out from the melting tank 10.

  Further, when the fixed crushing plates 31 to 33 need to be repaired or replaced due to deformation or breakage, the fixing bolts 38 of the base plate 35 that support the fixed crushing plates 31 to 33 are removed from the pedestal 37. Then, the fixed crushing plates 31 to 33 unitized together with the base plate 35 and the guide plate 34 can be taken out from the dissolution tank 2.

  As described above, in the present invention, the movable crushing plate 13 of the impeller 10, the entire impeller 10 and the fixed crushing plates 31 to 33 can be easily taken out from the dissolution tank 2 and repaired or replaced. . In addition, after taking out the whole impeller 10 and the fixed crushing plates 31-33 from the dissolution tank 2, and repairing or replacing | exchanging, what is necessary is just to assemble in the reverse order to the above.

  Further, the support shafts 16 provided at both ends of the cylindrical shaft 15 of the impeller 10 are supported by bearings via the bearing members 20, and the protrusions 21a formed on the bearing members are fitted into the holes 2c formed in the melting tank. Since the support shaft 16 is held, the support shaft 16 can be positioned and held accurately and easily at a predetermined position.

  Further, the projecting portion 12a formed on the blade plate 12 of the impeller 10 is fitted into the slit-like engagement holes 11a and 13a formed on the side plate 11 and the movable crushing plate 13, whereby the impeller 10, in particular, The strength of the movable crushing plate 13 can be increased. Further, if each side plate 11 of the impeller 10, the blade plate 12 and the movable crushing plate 13 are accurately formed by laser cutting or the like as in the above embodiment, it is possible to more firmly bond without backlash. The same applies to the guide plate 34 and the fixed crushing plates 31 to 33.
