A cyclone (90) consisting of a mesh (97) having a pellet discharge port (95) formed outside the housing (91) to discharge the pellet from which the coolant is separated at the upper end of the groove (94); A circulation line 100 circulating the separated and discharged cooling water; It is made, including.

The hopper 10 allows the synthetic resin sheath separated from the wire to be introduced.

The heater 20 ensures fluidity by heating the synthetic resin coating introduced into the hopper 10. At this time, the heater 20 is installed adjacent to the extruder 30 to heat the synthetic resin coating introduced into the extruder (30).

The extruder 30 is well known as shown in Figure 2 of the screw feeder 31 is provided with a transfer wing 31a by the motor 32 to the synthetic resin sheath ensured fluidity by heating the heater 20 Transfer extrusion by rotation. Power generated from the motor 32 is transmitted to the screw feeder 31 through the power transmission gearbox 33 to rotate the screw feeder 31.

The screen 40 is installed at the rear end of the extruder 30, as shown in Figure 2 and a plurality of through-holes 41 are formed to discharge the synthetic resin coating extruded from the extruder 30.

The cutting unit 50 is installed at the rear end of the screen 40 to cut the synthetic resin coating discharged through the through-hole 41 of the screen 40 to pellets of a predetermined size. Since the cut pellets are heated, they are solidified so that the sharp edges are naturally removed during cutting. The cutting unit 50 is known and the cutting blade 51 disposed at a predetermined angle as shown in Figure 2 is rotated by the motor 52 to cut.

The pellet accommodating part 60 accommodates the cutting part 50 and the cut pellets. Cooling water is added to the pellet accommodating part 60 to cool the cut pellets, and the injected coolant and cooled pellets are transferred to the transfer line 80.

The coolant input unit 70 serves to inject coolant into the pellet receiving unit 60, and a water tank 71 and a pump 72 for pumping coolant contained in the water tank 71, and pumping. Cooled water input line 73 is made to be introduced into the pellet receiving portion 60 side of the cooling water. Cooling water and cooled pellets introduced by the pumping pressure of the pump 72 are transferred to the transfer line 80.

The transfer line 80 is connected to the other side of the pellet receiving portion 60 so that the injected coolant and the received pellets are transferred.

At this time, the middle portion of the transfer line 80 is further provided with a cooling water discharge portion 82 is formed with a plurality of discharge holes 81 so that the cooling water flows downward by its own weight as shown in Figure 5, the transfer The cooling water recovery line 83 may be further provided to recover the cooling water branched from the cooling water discharge part 82 of the line 80 and discharged to the cooling water discharge part 82 to the water tank 71. In this case, the amount of cooling water introduced into the cyclone 90 can be significantly reduced, and thus the dehydration efficiency of the cyclone 90 can be improved.

In addition, when the coolant flows from the coolant discharge part 82, the pumping pressure of the pump 72 is lowered and the pellets are stagnant instead of being transferred from the transfer line 80, thereby causing clogging. In order to prevent this, as shown in Figure 5 is installed in the cooling water discharge portion 82 portion of the transfer line 80 and the transfer line 80 so that pellets that can be stagnant when the cooling water falls from the cooling water discharge portion 82 is transferred. It is preferable that the air injection unit 84 for injecting air in the conveying direction of the) is further provided.

At this time, the compressed air injected into the air injection unit 84 uses the compressed air generated by the air compressor 110 without using the compressed air by a separate compressor.

The cyclone 90 is made up of a housing 91 and a mesh 97 accommodated inside the housing 91 on the outside as shown in FIGS. The lower one side of the housing 91 is provided with a cooling water outlet (91a) for discharging the cooling water. The cooling water separated through the network of the mesh 97 is discharged to the cooling water discharge port 91a.

The network 97 is accommodated in the housing 91 and becomes a network having numerous network holes. In addition, an inlet 93 is provided at one lower side of the net body 97 to be connected with the transfer line 80 from the outside of the housing 91 so that the coolant and the pellets are injected, and a spiral rise on an inner circumferential surface thereof. Spiral grooves 94 forming a flow path are formed. In addition, the net body 97 is provided with a pellet outlet (95) formed to the outside of the housing 91 to discharge the pellet from which the coolant is removed at the upper end of the spiral groove (94).

The coolant and pellets transferred to the inlet 93 of the cyclone 90 are introduced, and the injected coolant is dropped through the network of the mesh 97 of the reticular body and discharged to the coolant outlet 91a of the housing 91. It moves up along the helical groove 94. At this time, the pellet is moved along the spiral groove 94 and the moisture remaining on the surface of the pellet is removed. The pellets moved along the spiral grooves 94 to remove moisture are discharged to the pellet outlet 95 provided at the upper end of the spiral grooves 94, and the coolant separated from the mesh 97 is transferred to the housing 91. It is discharged to the provided cooling water outlet (91a).

That is, according to the present invention, since a plurality of compressed air inlets 96 for injecting air to the inner circumferential surface of the mesh body 97 arranged along the spiral groove 94 are spaced apart from each other, the spiral of the spiral groove 94 The vortices are formed in a state consistent with the direction, so that the pellet injected downward of the net body 97 rises while being rotated by the vortex inside the net body 97, in particular, at a high speed along a helical groove 94. As you rotate it will rise.

At this time, of course, the dispersion of the vortex air by a number of nets are inevitable, but the size of the nets are much smaller than the pellets and suitable for the discharge of water, so that the moisture in the pellets is discharged into the nets as the pellets rotate and rise by the vortex. .

In order to form such a vortex, the air compressor 110 is connected to the compressed air inlet 96 outside the cyclone 90 to generate and generate compressed air, as well as the compressed air inlet 96. It is a matter of course that the pellets can be smoothly rotated and raised along the spiral groove 94 by the compressed air introduced into the spiral groove 94.

In addition, the pellet discharged to the pellet outlet (95) is a state in which the water is completely removed can be used as the contents, such as bedding, such as stuffed toys or pillows without additional drying. As described above, the present invention has high dehydration efficiency because the pellets discharged together with the cooling water rotate and rise at a high speed at a high speed along the spiral groove 94 to completely remove the water present in the pellets. In addition, unlike the conventional apparatus to proceed with the dehydration operation in the process of allowing the inflow into the dehydration container and the removal of the dehydrated recycled product from the dehydration container, a series of processes of removing the cooling water from the input of the synthetic resin coating Since it can be performed continuously without stopping, the productivity can be greatly improved.

In addition, the circulation line 100 may be connected to the cooling water outlet 91a of the cyclone 90 and the water tank 71 to circulate and recycle the discharged cooling water, and on the circulation line 100. Discharging pellets such as those generated during cutting into pellets by the cutting unit 50 or discharged through the net due to sizes smaller than a prescribed particle size that may be caused by collisions between pellets during cooling and conveying by cooling water. It is preferable that the drain port 101 is further provided.

In addition, the present invention is to remove the foreign material at the same time to ensure the fluidity by heating the synthetic resin coating of the various size and shape collected and separated from the wire, and to cool it with a cooling water to grind or cut to a certain size with the cooling water itself Pellet receiving portion 60 that can be directly received, the pellet containing such a coolant is injected; And

A conveying line 80 connected to one side of the pellet accommodating part 60 to convey the injected pellet and the cooling water; And

A housing 91 having a cooling water outlet 91a for discharging the coolant transferred through the transfer line 80 at one lower side thereof, and accommodated inside the housing 91 and having an outer side of the housing 91 at the lower side; In the inlet 93 is connected to the transfer line 80 and the cooling water and pellets are transferred to the input line is provided, the cooling water is separated from the pellet and the coolant is separated into a network having a myriad of net holes to discharge to the housing 91 Cyclone made of a mesh body 97 is formed on the inner circumferential surface of the spiral groove 94 forming a spiral upward flow path, the pellet outlet (95) for discharging the pellets separated from the cooling water at the upper end of the spiral groove 94 90, it may be composed of.

Therefore, while the pellets mixed with the cooling water introduced into the pellet receiving portion 60 is raised along the spiral groove 94 forming a spiral upward flow path made of a reticular body, the cyclone 90 rapidly rotates a long distance. Effectively separated from the cooling water, and discharged only through the pellet outlet (95) formed in the upper end of the cyclone 90 is separated from the cooling water to be able to re-fabricate the synthetic resin coating to cover the wire with such pure pellets.

In addition, this invention should not interpret a technical thought limited to the said Example.
