In general, plastic is a material that can be molded by heating, pressurization, or both, or a resin product using such a material. In general, plastic refers to a synthetic resin. In the final product, it has a lot of molecular weight and a large amount of chemical substances (gum) in solid form. In addition, as it is manufactured in the form of a polymer by polymerizing various substances with petroleum as the main raw material, the use and usage of the polymer compound with various functions and characteristics can be manufactured by polymerizing substances that can have the characteristics desired by the user. is increasing In addition, plastic is a type of petroleum compound using petroleum as its main raw material, and as it is manufactured in the form of a polymer, it is difficult to decompose and has excellent corrosion resistance, so it can be used for a long time. As it is widely used in various industrial products from daily necessities, its usage is rapidly increasing.

However, waste plastics that are discarded after use of plastics have a property of plastic that is difficult to decompose, so it is difficult to landfill, and when incinerated, various harmful gases are emitted and pollute the air environment, so it is difficult to treat waste plastics. . In addition, as the reserves of oil, including petroleum, which are fuels used to produce plastics, are reduced, the price of oil increases, and the need for reusing the oil present in the waste plastics is increasing according to the depletion of resources.

Accordingly, recently, an oil reduction device for waste plastics has been developed that reduces and recovers the oil contained in the waste plastic to increase the degree of resource recycling.

Korean Patent No. 10-0659244 (December 12, 2006, registered) discloses a "recycled oil processing system using waste plastics".

However, the conventional "recycled oil processing system using waste plastics" of the prior Korean Patent No. 10-0659244 discloses only recovering by extracting and reducing the regenerated oil from the waste synthetic resin by pyrolysis and storing it in the final storage tank. However, it is not disclosed to directly recycle the stored regenerated oil as a fuel for a burner provided in a reactor for thermally decomposing waste plastics. There is a disadvantage that the economic feasibility deteriorates due to the added cost and increased transportation cost.

Of the plurality of shafts 310, only the corresponding shaft 310 is exposed to the outside to carry out the exchange operation, and at the same time, a normal filtering process is possible with the remaining shafts 310 among the plurality of shafts 310, so that the corresponding shaft ( 310), the process waiting time due to the filter replacement operation does not occur, and thus has the advantage of increasing overall productivity.

In particular, in the present invention, a finer and more sophisticated filtration process is possible by additionally providing a fine material filtering network 316 other than the filter 315, and the axis through the suction passage 204 formed in the front of each supply passage 202 is provided. Since the filter 315 exposed to the outside in the slide process before and after 310 prevents the air from being introduced into the regenerated oil supply pipe L1 and injected into the regenerated oil supply pipe L1out on the outflow side of the regenerated oil supply pipe L1, the flow process of the regenerated oil Prevents problems such as deteriorating the quality of the regenerated oil due to the generation of air bubbles.

To this end, the present invention is configured as follows.

As described above, the basic contents of all components of the present invention have been described, and now, detailed detailed components for each component will be described.

The main body 200 is coupled between the inlet-side regenerated oil supply pipe (L1in) and the outlet-side regenerated oil supply pipe (L1out) to inject the regenerated oil into the inner shaft 310 and simultaneously inject the filtered regenerated oil into the outlet-side regenerated oil. It is a component for supplying to the supply pipe (L1out). Therefore, the main body 200 uniformly supplies the regenerated oil injected through the supply passage 202 to each insertion hole 201 to induce it to be filtered in a uniform amount through the internal shaft 310, and at the same time, the filtered regenerated oil It is to be discharged in a fixed amount through the discharge pipe (203). Accordingly, the main body 200 forms several hollow portions penetrating the other rear surface from the front surface to form an insertion hole 201 into which each shaft 310 is fitted, and each insertion hole 201 forms a predetermined interval and moves vertically. Each axis 310 that is arranged and fitted is positioned on the same straight line.

In addition, the main body 200 forms a supply passage 202 on one side to supply the regenerated oil injected from the inlet regenerated oil supply pipe L1in, and the supply passage 202 is injected into each insertion hole 201. By forming a plurality of pipes, the regenerated oil supplied through one inlet is uniformly supplied to each through-hole 201 to induce a filtration process of the shaft 310 inserted therein, and filtered from each shaft 310 . As a component for supplying the regenerated oil to the outflow side regenerated oil supply pipe L1out, a discharge pipe 203 is formed on the other side of the main body 200, and the discharge pipe 203 is connected to each through-hole 201. A pipe is formed so that the regenerated oil uniformly discharged through each insertion hole 201 is supplied to the outflow side regenerated oil supply pipe L1out through one discharge pipe 203 .

On the other hand, the body 200 forms several suction passages 204 as a means for discharging the air introduced into the body 200 while the shaft 310 slides back and forth to the insertion hole 201 of the body 200 . And, the suction passage 204 is located in front of the supply passage 202 located on one side of the main body 200 to form a hollow part that horizontally passes through each insertion hole 201, and each hollow part is arranged vertically to be positioned on the same straight line so that the air inside is discharged to the outside when each of the suction passages 204 is slid in the course of sliding movement of each shaft 310 . In addition, each suction passage 204 is connected to a conventional suction pump 205 provided to the outside to quickly discharge the air introduced into the interior so that air is not injected into the outflow-side regenerated oil supply pipe L1out.

As shown in FIG. 6 , the shaft 310 is a component for filtering the regenerated oil injected through the supply passage 202 of the body 200 . Therefore, the shaft 310 filters the regenerated oil distributed and supplied to each insertion hole 201 through the supply passage 202 and supplies it to the outlet side regenerated oil supply pipe L1out through the discharge pipe 203 . Accordingly, the shaft 310 has one end coupled to the slide guide shaft 321 of the cylinder 320 and the other end is slidably moved into each insertion hole 201 of the main body 200 to receive regenerated oil supply passage 312 . The first shaft 311 in which is formed, one end is coupled to the other end of the first shaft 311, and several discharge passages 314 having a structure in which regenerated oil is supplied from the first shaft 311 and sprayed to the side are formed. The second shaft 313 and the filter 315 that is intubated to the side of the second shaft 313 and filters the regenerated oil supplied from the discharge passage 314, and the filter 315 are coupled to surround the circumference of the filter 315, A fine material filtering network 316 for filtering fine foreign matter that is not filtered from the filter 315 may be included.

The first shaft 311 is a component for supplying the regenerated oil injected from the supply passage 202 of the main body 200 to the second shaft 313 . Accordingly, the first shaft 311 forms a supply passage 312 of a right-angled shape passing through the other end from the side, and is coupled in a form consistent with the supply passage 202 formed by each insertion hole 201 of the body 200. and serves to supply the regenerated oil injected from each supply passage 202 to the second shaft 313 . In addition, a coupling groove coupled to the second shaft 313 is formed at the other end, and the coupling groove has a thread formed on the inner side thereof to serve as a nut coupled to the second shaft 313 .

In addition, the first shaft 311 is provided with a pressure sensor (not shown) in the supply passage 312 is connected to the external control box 600, the filter 315 or the fine material filtering network 316 ), when the pressure increases due to clogging, a warning sound and a warning message are displayed through the control box 500 to inform the administrator.

Meanwhile, the second shaft 313 is a component for supplying the regenerated oil supplied from the first shaft 311 to the filter 315 . Accordingly, the second shaft 313 forms a discharge passage 314 receiving regenerated oil from the supply passage 312 of the first shaft 311 so that a uniform amount of regenerated oil is supplied to the filter 315 . Accordingly, the second shaft 313 forms a discharge passage 314 in which a groove of a certain length is horizontally penetrated from the center of one end and several pipes passing through the side from the end of the groove are formed, so that the first shaft 311 is formed. It plays a role of uniformly spraying the regenerated oil supplied from the lateral side to supply it to the filter 315, and the second shaft 313 is a circular block protruding horizontally from the center of one end to form a screw thread on the side. formed bolts, and the formed bolts are coupled to the coupling grooves of the first shaft 311 to serve to fix the second shaft 313 .

In addition, the second shaft 313 is accommodated so as not to rub against the insertion hole 201 during the sliding movement of the intubated filter 315 and the fine material filtering net 316 by reducing a portion of the outer diameter to a thin length by a predetermined length. It is preferable to secure a space, and several blocks are formed on the side to secure a space at a predetermined interval between the intubated filter 315 and the regenerated oil price filter 315 injected through the discharge passage 314 to the inside of the filter 315. It plays a role in inducing a uniform supply.

Meanwhile, the filter 315 is a component that primarily filters the regenerated oil uniformly supplied from the second shaft 313 . Accordingly, the filter 315 primarily filters relatively large foreign substances and supplies it to the fine material filtering network 316 . Accordingly, the filter 315 is configured as follows. The filter 315 is in the shape of a circular tube having a hollow inside, and is intubated to fit into the side of each block formed on the side of the second shaft 313 to supply regenerated oil from the second shaft 313 . and several filtering grooves penetrating from the inner side to the outer side are formed to filter the regenerated oil injected through the discharge passage 314 of the second shaft 313 . At this time, the filter groove does not easily clog the filter groove because it filters only relatively large foreign substances in proportion to the standard of the product, so there is an advantage that it does not need to be replaced for a long time. If the fastening part of 313 is rotated and separated, it can be easily exchanged and can be used again by cleaning the inside and outside of the filter, so it also has the advantage of low maintenance cost.

And, as shown in FIG. 21 , the fine material filtering network 316 is a component for secondarily filtering fine foreign substances that are not removed through the filter 315 . Therefore, the fine material filtering network 316 is as simple as possible in structure so that it is possible to remove fine foreign substances only with the fine material filtering network 316 without installing an additional filtering device. Accordingly, the fine material filtering net 316 forms a net made of weft and warp yarns having a mesh shape of a certain standard, and is combined in a shape wound on the side where the filtering grooves of the filter 315 are formed, and is filtered from the filter 315. It plays a role in removing the fine foreign matter that has not been In addition, the fine material filtering network 316 has the advantage of being able to filter fine foreign substances of various sizes by variously changing the specifications of the internal mesh.

As such, the shaft 310 enables a finer filtration process through the filter 315 and the fine material filtering network 316 without additionally installing an expensive filtration device, and the structure is simple and exchange is convenient, so the productivity is excellent. have an advantage

The cylinder 320 is a component that induces the forward and backward sliding movement of the shaft 310 coupled to the front so that the filter can be exchanged without stopping the entire process. Therefore, this cylinder 320 is connected to the control box 600 connected to the outside to individually control each cylinder 320, so that only the cylinder 320 connected to the shaft 310 that needs replacement or repair is automatically slidingly moved. By controlling it, the filter 315 and the fine material filtering net 316 can be easily exposed to the outside even if the operator does not directly slide the shaft 310 . Accordingly, the cylinder 320 is composed of a accommodating base 322 having an accommodating space formed therein and a slide guide shaft 321 coupled to the accommodating space of the accommodating base 322 to slide forward and backward, and the accommodating base 322 ) is wire-connected to the control box 600 located outside, so that individual control of the inner slide guide shaft 321 is possible, and it is possible to control each slide guide shaft 321 to automatically slide back and forth with a simple button operation. Thus, it is convenient to exchange the filter 315 and the fine material filtering network 316, and it is possible to precisely control the supply and discharge of the regenerated oil by constantly adjusting the interval at which the shaft 310 slides.

As such, the accommodating base 322 is linked with the control box 600 to automatically control the front and rear sliding radius of each slide guide shaft 321, and at this time, the process of automatically sliding is performed first and second. , it is set to be driven in the third order to induce sequential accurate sliding movement.

The pipe passing through is blocked so that the filter 315 and the fine material filtering net 316 can be exchanged, and in the second driving step, after the exchange of the filter 315 or the fine material filtering net 316 is finished, the slide guide shaft By controlling the 321 to slide backward, the suction passage 204 of the main body 200 and the supply passage 312 of the first shaft 311 are first connected to the inside of the filter 315 in the forward sliding process. The inflow of air is removed to prevent air from flowing into the outflow-side regenerated oil supply pipe (L1out), and in the third driving step, the cylinder shaft 211 is completely returned to the rear to provide a supply passage for the first shaft 311 . 312 and the supply passage 202 of the main body 200 are connected to At the same time as the supplied regenerated oil is filtered, the discharge pipe 203 of the main body 200 and the fine material filtering network 316 are connected to supply the filtered regenerated oil to the outflow side regenerated oil supply pipe L1out.

By describing the filtration process of the regenerated oil supplied from the inlet regenerated oil supply pipe L1in using the filtration device 700 and the exchange process of the filter 315 and the fine substance filtering net 316, the mode of operation of the present invention will be described in detail. I want to describe

First, the filtration process of the filtration device 700 will be described. The regenerated oil supplied from the inlet regenerated oil supply pipe L1in is injected through the supply passage 202 of the main body 200 and supplied to the first shaft 311 of each shaft 310, and The regenerated oil injected through the supply passage 312 is supplied to the second shaft 313 , and the supplied regenerated oil is uniformly sprayed laterally through the discharge passage 314 of the second shaft 313 to the second shaft. The regenerated oil supplied to the filter 315 passes through the filtration groove of the filter 315 and undergoes a primary filtration process, and the filtered regenerated oil is Secondary filtering through the fine material filtering net 316 surrounding the exterior of the filter 315, additional filtering of fine foreign matter that has not been filtered through the filter 315 is sprayed to the outside, and the injected regenerated oil is passed through each through-hole It is injected into the supply passage 202 connected to 201 and is supplied to the outflow side regenerated oil supply pipe L1out.

On the other hand, as shown in FIG. 22 , the pressure increases due to the clogging of the filter 315 or the fine material filtering net 316 in one shaft 310 , and replacement is sometimes required. When such a problem occurs, when the pressure sensor installed inside the first shaft 311 exceeds a certain pressure, a warning sound is generated through the connected control box 600, and at this time, the corresponding shaft 310 in which the problem occurs is slidingly moved forward. Thus, while exposing to the outside of the main body 200, at the same time blocking the connection between the supply passage 202 and the discharge pipe 203, the supply of regenerated oil is stopped, and a fine material filtering network covering the exterior of the filter 315 exposed to the outside ( 316) is removed to proceed with the repair and replacement of the filter 315, and by combining the new fine material filtering net 316 with the exterior of the filter 315 on which the work is completed, it is returned to the inside by sliding backward.

At this time, the filter 315 exposed to the outside returns to the inside with a large amount of air introduced into the inside. If the air inside is not removed, the air flows through the discharge pipe 203 to the outlet side regenerated oil supply pipe L1out. Inflow, problems such as lowering the quality of the regenerated oil occur. In order to prevent this, as shown in FIGS. 24-26, the supply passage 312 of the first shaft 311 is connected to the suction passage of the main body 200 by controlling the cylinder 320 while the filter 315 slides backward. The supply passage 312 of the first shaft 311 is controlled to completely remove the air introduced into the interior through the suction pump 205 installed outside the suction passage 204 by connecting it to the 204 and slide it back again. is connected to the supply passage 202, and the fine material filtering network 316 is connected to the discharge pipe 203 to prevent air from flowing into the outflow side regenerated oil supply pipe L1out, and at the same time, a normal filtration process is possible.

In addition, as shown in FIG. 27 , the filtering device 700 having such a structure can be added or reduced by adjusting the internal shaft 310 and the insertion hole 201 of the main body 200 by the same number. And if it is provided with a plurality of filtration devices and only a connection means connecting each supply passage 202 and the discharge pipe 203 is provided, it is possible to further connect any number of devices to perform a more sophisticated and fine filtration process.
