Recently, as a way to recycle waste synthetic resins without incineration or landfill, pyrolysis emulsification methods and devices for extracting useful oils by pyrolyzing waste synthetic resins have been widely used.

As anyone can understand, the above-mentioned emulsification process is a pyrolysis process to obtain gaseous oil components by heating and decomposing waste synthetic resin at 300°C to 600°C, and fractional distillation to liquefy and separate gaseous oil components. process can be divided into

To explain this more specifically, first, the thermosetting resin, metal, wood, etc. that are not thermally decomposed from the collected waste synthetic resin are roughly separated, and the selected thermoplastic synthetic resin is cut or crushed to an appropriate size, and then the selected thermoplastic synthetic resin ( waste synthetic resin) is charged into the inlet of the decomposition furnace. At this time, the waste synthetic resin is usually preheated to 200°C to 250°C and charged into the decomposition furnace in an almost molten state or in a cut and pulverized state.

The waste synthetic resin charged in the decomposition furnace is heated to 300°C~600°C by a heating means while moving along the decomposition furnace by a screw conveyor, whereby the waste synthetic resin is decomposed into oil (oil) components and vaporized, and partially mixed Thermosetting resin, metal, wood or synthetic resin additives are discharged to the outside of the decomposition furnace by the screw conveyor as undecomposed residues (Ash).

And the oil component decomposed and generated in the decomposition furnace is introduced into the condenser through the gas outlet in a gaseous state, liquefied, separated, and then transferred to a storage facility through a post-treatment process and stored.

On the other hand, the gaseous oil component introduced into the condenser passes through a thin condensing pipe during the condensation process. At this time, the gaseous oil component passing through the condensing pipe is condensed by the cooling water and produced as regenerated oil.

However, the above-mentioned gaseous oil component contains a large amount of polymer wax component, and this polymer wax is adhered to the wall surface of the condensing pipe during the condensation process and blocks the condensing pipe, causing a problem in the operation of the emulsifying device. there was

In order to solve this problem, conventionally, the outside of the condensing pipe is kept warm at 200° C. or more, but there is a problem in that excessive energy is consumed.

On the other hand, the condensing pipe cleaning means 140 is to be accommodated in the third chamber (112c) by separating the fixed material (S) adhered to the inside of the condensing pipe (130).

The condensing pipe cleaning means 140 includes the shaftless screw flights 142 and the power transmission means 150 for interlocking the driving of the shaftless screw flights 142 .

Shaftless screw flights 142 are, as shown, the blade 144 is extended in the shape of a spiral in a state in which the shaft is excluded, and each shaftless screw flight 142 is a cooling container 110 . Through the upper end of the first chamber (112a) is inserted into each condensing tube (130).

And the extension ends of the shaftless screw flights 142 inserted into each of the condensing tubes 130 extend into the interior of the third chamber 112c.

In addition, the power transmission means 150 includes one or more driving motors 154 connected to the drive shafts 146 to which the gear 152 is fixedly mounted via a coupling. At this time, although not shown, the driving motor 154 may be supported by a sub-frame extending from the frame 148 .

On the other hand, the gears 152 fixedly mounted on each drive shaft 146 are meshed with each other so that when the drive shaft 146 connected to the drive motor 154 rotates, they are interlocked to rotate. For this purpose, the gears 152 are the same is made to

That is, the gears 152 are formed to have the same number of teeth, the same number of teeth, and the same pitch circle. Therefore, when any one gear 152 rotates, the other adjacent gears 152 that are meshed with each other also rotate in conjunction with each other, whereby each of the shaftless screw flights 142 are also rotated while the condensing tube 130 is rotated. The fixed material (S) attached to the wall can be scraped off, and the fixed material (S) separated from the condensation pipe 130 is transferred to the third chamber (112c) side.

And, although not shown, the reason why the gears 152 are arranged adjacent to each other on imaginary vertical and horizontal lines is because the condensing tubes 130 are arranged adjacently along imaginary vertical and horizontal lines.

4 (A) shows a state in which one gear 152 and another adjacent gear 152 are arranged adjacently along an imaginary 45 degree diagonal line in plan view, in this case the neighboring gears Since the point at which the 152 rotates in the same direction occurs, to prevent this, the gears 152 are provided as an “A” type gear 152 and a “B” type gear as shown in FIG. 4(A). In the state arranged at 152, the drive motor 154 is additionally connected to any one of the gears 152 in the gear 152 row with the gears 152 rotating in the same direction to rotate the remaining gears 172. can

And as the gears 152 rotate in a clockwise or counterclockwise direction in a plan view, the shaftless screw flights 142 connected via the drive shaft 146 also rotate in the clockwise or counterclockwise direction while the fixed material (S) are sequentially arranged so as to be scraped toward the third chamber (112c).

Here, the "A"-shaped gear 152 has gear teeth formed on the upper side of the outer peripheral surface as shown in FIG. 4A, and the "B"-shaped gear 152 is the "A"-shaped gear 152 . The gear teeth are formed on the lower side of the outer circumferential surface as shown in FIG. 4 so as not to interfere with the gear teeth of the gear 152 to which the drive motor 154 is connected, that is, the "D" shape shown in FIG. Gear 152 is formed on the entire outer peripheral surface of the gear teeth.

And although not shown, the reason why the gears 152 are arranged adjacently along an imaginary 45 degree diagonal line is because the condensing tubes 130 are arranged adjacently along a virtual 45 degree diagonal line.

Hereinafter, the operating state of the condenser for the waste synthetic resin emulsification apparatus formed as described above will be briefly described.

Gas (G) flows into the first chamber 112a through the gas inlet pipe 116 under a state in which the coolant is circulated into the second chamber 112b through the coolant inlet pipe 118 and the coolant outlet pipe 120 . When done, the gas (G) is guided into the condensing pipe 130 through the upper end of each condensing pipe (130).

And the gas (G) guided into the condensing pipe 130 is condensed by the cooling water as it passes through the second chamber 112b in which the cooling water circulates. At this time, the gas G is condensed by the cooling water and regenerated oil (O). The phase change is accommodated in the third chamber (112c). And a part of the polymer wax (wax) component included in the gas (G) is accommodated in the third chamber (112c) side together with the regenerated oil (O), and the remaining polymer wax (wax) component is condensed in the condensation pipe 130 during the condensation process. fixed to their walls.

As described above, when the polymer wax component is adhered to the inside of the condensation pipe 130 , power is applied to the driving motor 154 of the condensing pipe cleaning means 140 to operate the driving motor 154 .

When the driving motor 154 operates, the driving shaft 146 connected to the driving motor 154 and the gear 152 fixedly mounted to the driving shaft 146 rotate, and the driving shaft 146 to which the driving motor 154 is connected. As the gear 152 fixedly mounted to the rotational axis rotates, the other gears 152 meshed with each other also rotate while rotating each drive shaft 146 to rotate the respective shaftless screw flights 142 .

When each of the above-described shaftless screw flights 142 rotate, the spiral blade 144 of each shaftless screw flight 142 scrapes off the adherent (S) attached to the wall surface of the condensing tube 130, and the spiral blade ( The fixed substances S separated by the 144 are transferred to the third chamber 112c side by the rotating spiral blade 144 and accommodated in the third chamber 112c.

In the above, it has been described that the condensing pipe cleaning means 140 is operated to separate the adhering material S while the polymer wax component is fixed inside the condensing pipe 130, but the condensation pipe cleaning means 140 is in the first chamber. (112a) may operate at the same time as the gas (G) is introduced into the interior.

The condenser 100 for the waste synthetic resin emulsifier according to the present invention formed in this way automatically removes the wax component adhering to the wall surface of the condensing pipe 130 by the shaftless screw flight 142 rotatably disposed inside the condensing pipe 130 . Separation/discharge, and also because it can prevent the wax component from adhering to the wall of the condensing tube 130, not only can the efficiency of condensation be increased, but also the cleaning cycle of the condenser 130 can be delayed, so that a productivity shape can be expected.

In the foregoing, specific embodiments of the present invention have been described and shown, but it is common knowledge in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. It is self-evident to those who have Accordingly, such modifications or variations should not be individually understood from the technical spirit or point of view of the present invention, and modified embodiments should be said to belong to the claims of the present invention.
