Description

Recycling device using waste styrofoam {RECYCLE DEVICE USING A WASTE STYROFOAM}

The present invention relates to a regeneration apparatus using waste styrofoam, and more particularly, by heat extruding the crushed waste styrofoam and solidified to form a resin-like strand, and cutting the solidified resin-like strand to a certain standard pellets of a resin material The present invention relates to a reproducing apparatus using waste styrofoam.

In general, the recycling method using the waste styrofoam is a collection step for the collector to collect the waste styrofoam, and if the additional waste is mixed with the collected waste styrofoam, the additional foreign matter is separated from the waste styrofoam. Next, the waste styrofoam after the classification step is to proceed to the foreign matter removal step of removing foreign matters such as food waste. Next, the waste styrofoam from which the foreign matter is removed is subjected to a grinding step of grinding finely. Subsequently, the waste styrofoam finely pulverized by the crushing step is subjected to a sacrificial step of forming ingot form through a melting process through a sachet. Next, the ingot-type waste styrofoam in which the volume is reduced to 1% to 60% by the reduction step is subjected to a pellet molding step in which a pellet is formed into pellets through an extruder after regrinding.

Recycling method using such waste styrofoam is to form the pellets through the collection step, sorting step, foreign material removal step, grinding step, applying step, and pellet molding step, after which the pellets are made of artificial wood, artificial brick, Recycled resins, coatings such as flame retardant paints, and solid fuels are recycled.

On the other hand, as a conventional technique for the regeneration device using the waste styrofoam, disclosed is a waste polystyrene automatic regeneration device and method (hereinafter, Patent Document 1) of the Republic of Korea Patent Publication No. 10-2001-0102860. Looking at the conventional patent document 1, Figure 1 is a view showing a simplified view of Figure 1 of the patent document 1, in the conventional patent document 1 waste styrofoam pulverized by the grinder (1) primary melt feeder (2) and 2 When the primary melt feeder and the tertiary feeder 3 are extruded while being heated, a plurality of pellet strands 4 are extruded through the outlet. Next, after the plurality of pellet strands 4 have passed through the cooling device 5, they are cut to a certain length by the cutter 6, and the cut pellets are sucked by the vacuum pump 8 to pellet through the conduit 7 Stored in the reservoir (9).

Here, looking at the cooling device (5) of the conventional patent document 1, the conventional cooling device (5), as shown in the drawing, the pellet strands (4) in the state of storing the water in the water tank is submerged in the water cooled and cooled Will be performed.

Looking at the configuration similar to the configuration for such a cooling device (5), in the pellet manufacturing apparatus (hereinafter referred to as Patent Document 2) using the styrofoam of the Republic of Korea Patent Publication No. 10-1778536 (hereinafter referred to as Patent Document 2) reference numeral 10 of Patent Document 2 A cooling tank (reference numeral 210 of Patent Document 2) for cooling a pellet strand similar to that of a cooling water is disclosed.

In addition, in the solid fuel forming apparatus (hereinafter referred to as Patent Document 3) using the waste, which is similar to the cooling device 5, the Korean Utility Model Publication No. 20-2009-0008925 (hereinafter referred to as Patent Document 3) A cooling method is disclosed in which a part of reference numeral 141 is immersed in a cooling tank (reference numeral 143 of Patent Document 3) to cool waste (similar to pellet strands).

As shown in Patent Literature 1, Patent Literature 2, and Patent Literature 3, the conventional waste styrofoam is molded into pellet strands after being extruded, and the molded pellet strands are cooled by cooling water in a state in which a coolant such as water is stored in a cooling bath. And harden.

However, such a conventional cooling apparatus has the following problems.

First, in the conventional cooling apparatus, since the pellet strands continuously pass through the cooling water, the pieces separated from the pellet strands and carbon residues formed during heating are cooled in the cooling tank (the cooling apparatus 5 of Patent Document 1 and the cooling of Patent Document 2). And similar to the cooling tank 143 of Patent Document 3).

In addition, the conventional cooling tank is formed with the upper part opened because the pellet strand must pass through the cooling water for cooling, and a roller or a conveyor for transferring the pellet strand into the cooling water separately so that the pellet strand can be sufficiently locked in the cooling water. It is provided. As described above, in the conventional cooling device for cooling the pellet strands, the upper space of the cooling tank is opened, and since the conveying device such as a roller is provided therein, dust is introduced through the upper space or debris generated during work is cooled. Lubricant of the feed roller is also introduced into the cooling system.

That is, the conventional cooling tank adopts a method in which the pellet strands pass through the cooling water of the cooling tank, thereby cooling the pellets or carbon residues left from the pellet strands in the cooling water, thereby contaminating the cooling water. Since the space is open, dust or debris flows into the upper space of the cooling tank, thereby contaminating the cooling water.

Since such problems occur, the conventional cooling tank periodically discharges the contaminated cooling water and supplements it with new cooling water. At this time, since the discarded cooling water contains foreign substances such as pellets, carbon residues, dust, debris, and lubricating oil, it is classified as waste water, and therefore, a separate operation must be performed.

That is, since such wastewater disposal operations occur periodically, the pellet forming operation must be stopped every cooling water replacement operation cycle, thereby reducing the pellet production efficiency.

In addition, waste water causes environmental pollution, which increases the cost of pellet manufacturing because the operator has to secure a waste water treatment manpower, have a waste water treatment facility, or perform waste treatment through an external waste company. .

For this reason, some pellet manufacturers sometimes generate illegal discharges in order to reduce the cost of wastewater treatment.

Therefore, in order to prevent the discharge of the waste water without permission, the government has to visit the professional supervisor periodically, causing the problem of increasing the intensity of the supervisors.

As such, conventional cooling baths for cooling pellets have increased costs for treating wastewater, causing environmental pollution by wastewater, and causing problems that increase the work intensity of government inspectors.

Therefore, at present, a cooling tank for cooling pellets requires a technical solution that does not incur waste water treatment costs, does not cause environmental pollution, and does not increase the work intensity of the government supervisor.

On the other hand, in the waste styrofoam regeneration system (Patent Document 4) of the Republic of Korea Patent Publication No. 10-2007-0041646 (patent document 4) is a thin diameter plastic (similar to pellet strands) discharged from the injection molding machine (34, Patent Document 4, similar to the extruder) ) Is cooled by the water injected from the water injection nozzle (reference numeral 36 of Patent Document 4), and the injected water is accommodated in the drip tray (reference numeral 38 of Patent Document 4), thereby cooling the pellet strands. have.

The cooling method of Patent Document 4 has the advantage that the plastic (similar to the pellet strand) does not need to be immersed in the drip tray (similar to the cooling tank) by using a water jet nozzle, but the pellets in the drip tray (similar to the cooling tank) There is no choice but to retain carbon residues. Furthermore, since the top of the drip tray (similar to the cooling tank) is opened to accommodate the sprayed water, foreign substances such as dust and debris are inevitable. Water can only be formed from wastewater.

That is, since the conventional cooling method such as Patent Document 4 generates wastewater, as described above, the cost for treating wastewater increases, causing environmental pollution by wastewater, and increasing the work intensity of the government inspector. Because it causes them, measures for this are needed.

On the other hand, the pellet strand discharged through the conventional extruder is often conveyed by the roller (reference numeral 230 of patent document 2, reference numeral 44 of patent document 4).

However, the method of transferring the pellet strand discharged through the extruder in contact with the roller should be performed by the operator to insert the first end of the pellet strand into the roller every time the pellet strand is discharged. Since the drawing operation is very cumbersome, not only the pellet production efficiency is reduced, but also a safety problem occurs that a dangerous situation such as a worker's hand is caught on the roller when drawing the pellet strand into the rotating roller.

Accordingly, in the conventional patent document 3, the pellet strands are transferred through a conveyor (reference numeral 141 of Patent Document 3) instead of the method of introducing the pellet strands into the rollers, in which case the pellet strands are discharged from the ejector. In the high temperature of the liquid phase is discharged to the conveyor as it is stuck to the belt of the conveyor. For this purpose, in Patent Document 3, the pellet strand discharged from the ejector is immediately cut, and the cut pellet pieces are dropped in the cooling tank to be cooled, and thus are transported without sticking to the conveyor. Waste water is generated, and furthermore, since the cutting operation of the pellet strand is performed before the cooling of the pellet strand, the shape of the pellet is not constant, which causes a problem that the application field is limited, and the cutting operation is performed in the liquid phase of the pellet. Due to the demand for precise work, it is difficult to cut many pellet strands at once.

Therefore, the pellet strand discharged through the conventional extruder can be transported without transporting in a roller-like manner, and furthermore, the pellet strand can be transported without sticking to the conveyor without cutting the molten pellet strand. In addition, even if a large amount of pellet strands are transported, there is a need for a technical solution so that the shape of the cut pellets is formed uniformly.

On the other hand, referring to Patent Document 1, as shown in Figure 1, after the operation of the third-purpose feeder (3, similar to the extruder) a plurality of pellet strands (4) after the cooling device (5), The cutter 6 is cut to a certain length, and the cut pellets are sucked by the vacuum pump 8 and stored in the pellet storage tank 9 through the conduit 7.

Here, since the vacuum pump 8 sucks the cut pellets using a strong suction force, foreign matter such as dust or debris remaining around the cutting machine or around the inlet of the conduit 7 is also sucked together with the cut pellets.

Therefore, since the storage tank 9 has foreign substances such as not only cut pellets or dust or debris, but also results in a problem of degrading the quality of the pellets.

In addition, conventionally cut pellets may be transferred by a method using a ring blower (not shown). The ring blower system uses a ring blower (not shown) for injecting strong wind at the inlet of the conduit 7 without using the vacuum pump 8 so that the strong wind is injected into the conduit 7. The pellets are conveyed to the conduit 7 by way of example.

Since the method using the ring blower strongly inhales outside air in order to inject strong air, dust or debris continuously flows around the ring blower, so that dust or debris continuously flows along with the transfer of pellets. In addition to causing the problem of deteriorating the quality of the pellets as well as the continuous inflow of external dust or debris in a state in which dust or debris is continuously scattered around the conduit 7 in the workplace, the working environment of the workplace Will cause problems that worsen.

Therefore, the operation of transporting and storing the cut pellets prevents dust or debris from entering and storing together with the pellets, and prevents dust or debris from entering the workplace or scattering of dust or debris during the pellet transport operation. There is a need for technical solutions that will not deteriorate the working environment.

The bucket part 125 is moved in the same direction as the conveying direction of the bucket drive chain 124.

Here, the conveying direction of the bucket drive chain 124 will be illustrated in a clockwise direction.

In such a state, the bucket part 125 moves upward from the bottom while spreading the remaining pellets around the curved receiving plate 121c, and after the upper roller 122 passes, the moving direction is upward. Since the opening space of the bucket part 125 is directed downward, the pellet accommodated in the bucket part 125 is discharged to the pellet discharge port 121b side at this time. In this case, the pellet discharged from the pellet discharge port 121b side is accommodated in the pellet storage tank 130, and the remaining pellets not discharged to the pellet discharge port 121b side are lower bent receiving plate 121c of the bucket casing 121. Will be gathered again.

Then, the operator opens a cover (not shown) covering the lower outlet of the pellet storage tank 130 as necessary, and puts the pellets in the pellet storage tank 130 in a large-capacity tone bag.

As such, when the recycling apparatus using waste styrofoam according to an embodiment of the present invention transfers and stores the cut pellets, the pellets are transferred by the bucket casing 121 so that the bucket part 125 is hidden. Since dust or foreign matter does not flow into the pellets and the pellets are not conveyed using air, the dust and foreign matters are not generated by the conveying operation, so that the working environment of the workplace is not deteriorated.
