Recently, due to the advancement of industry and improvement of living standards, various forms of waste have been rapidly increasing, and attention has been focused on waste disposal methods. Wastes are classified into industrial wastes whose sources and items are identified, and general wastes which are discharged from households, but the composition and properties of the wastes are remarkable. Industrial wastes are homogeneous in size and easy to manage, while domestic wastes are uneven and fluctuate, and the amount of waste generated depends on the scale of the facility and is widely dispersed in Korea.

Especially, it was convenient to use various polymer compounds according to the industrial revolution and development of petrochemical industry by applying them to real life. However, the disposal of wastes due to the industrial development for the convenience of life is very problematic , And products made of synthetic resins such as tires, vinyls, and plastics, which are widely used in various industrial fields and daily life, are only partially recycled after use, and most of them are classified as waste and buried or incinerated.

Such plastic waste, such as synthetic resin, is bulky compared to its weight, so that the landfill cost is not only larger than that of general waste but also does not decay even if it is landfilled. Especially, the recycling rate of vinyl and waste plastics is lower than other waste.

Recently, the Ministry of Environment recognizes that waste plastic is a resource, and in order to increase the recycling rate of waste plastics, it notifies the quality standards of solid fuel products using waste plastics, and actively supports them as an alternative fuel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Even if the terms are the same, it is to be noted that when the portions to be displayed differ, the reference signs do not coincide.

The terms to be described below are terms set in consideration of functions in the present invention, and may be changed according to a user's intention or custom such as an experimenter and a measurer, and the definitions should be made based on the contents throughout the present specification.

1 shows a process diagram of an RPF manufacturing system according to the present invention.

The RF manufacturing apparatus according to an embodiment of the present invention, the crusher 11 for cutting the supplied raw material primarily, the wind separator 13 for sorting the raw material cut primarily by using a wind power, and the A pulverizer 15 which cuts the raw material selected by the wind separator 13 in a secondary manner, a composite separator 16 which separates and removes foreign substances having a high specific gravity and metal foreign substances contained in the secondary cut raw material, and the composite separator. And a molding machine 19 for compressing the final raw material separated from 16 to form the RPF.

In particular, before the raw material is supplied to the crusher 11 may be further provided with a bongbong crusher 8 for dissociating the aggregated portion of the raw material and a magnetic separator 9 for removing metal foreign matter contained in the dissociated raw material. .

There is a problem that it is difficult to select the naked eye because the raw materials are often aggregated in the course of visual selection. Therefore, it is preferable to first pass through a shredding process using a bong after the transfer to the input conveyor. After the process, the raw material supplied to the input conveyor may be subjected to a visual screening process, but a magnetic separator process may be further performed to remove the metal foreign substances contained in the raw material.

However, it may further include a magnetic separator 12 for removing metal foreign matters downstream of the crusher 11 and a magnetic separator 12 for removing metal foreign matters downstream of the wind separator 13.

Vinyl and waste plastic that are introduced into the shredder contains water, but the water contained there is a disadvantage that can not be utilized in the RPF manufacturing process. Therefore, it is preferable to remove water through the water eliminator before entering the crusher. The water eliminator can supply low humidity winds and it can be possible to apply heat artificially, but there is a risk of fire, so be careful in its operation.

The crusher is to crush the incoming vinyl and waste plastic evenly, and in the case of vinyl, the crusher is crushed to a size of approximately 100 mm x 100 mm. The raw material passing through the crusher is separated from vinyl and the like by the metal foreign substances wrapped between the vinyl and the waste plastics. Therefore, it is removed by using a magnetic separator.

The magnetic separator feeds the raw material passing through the crusher along the conveyor belt, and a rotating magnetic belt is provided on the top of the conveyor belt to remove metal impurities.

The raw material passed through the above process is transferred to the wind separator 13. The wind power sorter 13 is characterized by moving the raw material by the wind power, and selects only the raw material moved over a predetermined distance.

The wind-powered sorter supplies wind power with a predetermined pressure to the incoming raw material, and the distances to be sent according to the wind are different according to the specific gravity of each material. In the case of vinyl and waste plastics suitable as raw materials in the present invention, the specific gravity is relatively small and moves away, and the metal foreign substances and the like are moved to a relatively short distance.

Therefore, only the vinyl and waste plastics moved far away are collected and transferred to the next process.

In addition, the system may further include a trommel screen device for separating fine particles by size. The Trommel screen device functions to remove minute foreign matter (glass powder, bottle cap, golf ball, etc.) by dividing the screen into three equal sizes.

Such a trommel screen device may be provided at any location in the system.

In the present invention, it is also possible to configure the wind selector 13 to supply warm air with low humidity to remove moisture contained in the vinyl and the waste plastic. In this case, there is no need for a separate water eliminator and no additional process is required, so that the system can be operated more efficiently.

Raw material passed through the wind separator 13 may be subjected to a magnetic separator again. This is because metals having a relatively small volume can pass through the wind separator 13 by being buried in vinyl or the like.

The raw material passing through the wind separator 13 is introduced into the grinder 15 through the conveyor belt. The crusher 15 is similar to the crusher 11 and performs a function of cutting the raw material into an appropriate size. However, it is preferable that the grinder 15 cuts the waste vinyl so as to have a size of approximately 30 mm X 30 mm. The feature of the present invention is that it is subjected to two cutting processes, namely a crusher and a crusher, the cut sizes of which are different from each other. The crusher performs a primary cutting operation in order to drop mixed metallic impurities and dissociate the waste plastics, and the crusher performs a secondary cutting operation in a size that can be utilized by being introduced into a molding machine. Therefore, a magnetic separator is provided between the crusher and the crusher to perform the aforementioned function.

There is a possibility that the raw material discharged through the grinder 15 still contains metal foreign matters and the like. Therefore, it is finally separated by using a composite separator.

The composite separator 16 may simultaneously perform a function of separating raw materials according to specific gravity using wind power, and a function of separating metal foreign matter using magnetic force.

At this time, after the wind power is applied to the input raw material, the raw material moved smaller than the predetermined distance is removed, and the metallic foreign substance contained in the raw material moved farther than the predetermined distance is removed using the magnetic force.

4 is a view for explaining the structure and operation principle of the compound separator 16.

Compound separator 16 has an inlet on the upper side of the plastic and plastic 101, a large volume of metal foreign material (102) transferred from the conveyor belt (29). A small volume of metal foreign material 103 is introduced. First, the wind power is generated from the injection nozzle 32 connected to the pneumatic pump 31 and acts on the raw material introduced. The relatively large volume of the metal foreign material 102 will descend, and the vinyl and plastics 101 having a small specific gravity and the small volume of the metal foreign material 103 will move in the horizontal direction.

The composite separator 16 divides the discharge port into two, such that a large volume of metal foreign material 102 is discharged to the near side 36 from the injection nozzle 32, and vinyl 101 is discharged to the far side 35. It is composed.

However, a small volume of the metal foreign material 103 may be moved to the outlet of the far side 35, in the middle of which provides a fixed magnetic material 41 and the drum member 40 to rotate around the small, The volume of metallic foreign material 103 makes it adhere to the drum member 40.

The small volume of metal foreign material 103 attached to the drum member 40 rotates together with the drum member, and is separated from the drum member 40 in a region where the magnetic material 41 does not exist, and is discharged to the outlet near to the drum member 40. It is a structure.

If there is no injection nozzle 32 in the composite separator 16, the problem that the vinyl 101 is discharged together with the metal to the outlet of the close side. Therefore, the present composite separator 16 is characterized by the injection nozzle generating the wind power.

5 shows the connection structure of the grinder 15 and the composite separator 16. That is, a reverse conveyor 28 and a blower 55 are further provided between the grinder 15 and the composite separator 16, and the reverse conveyor 28 combines the fuel discharged from the grinder 15 into the composite. It is preferable to transfer in a direction away from the separator 16, the blower 55 to supply wind power to the discharged fuel to transfer the raw material of a predetermined weight or less to the composite separator 16 side.

First, raw materials such as metal, plastic, and vinyl are mixed or a relatively large material is introduced through a conveyor to a grinder. The grinder 50 grinds the introduced material by using a high speed rotation such as a cutter.

However, in the case of light vinyl by the high-speed rotation of the grinder 50 may be a problem of floating to the top of the grinder cutter without grinding. Therefore, it is preferable that a push device 60 is additionally installed to press these vinyls so that they do not float in the air. The push device is a form in which a pressing portion 62 connected through a rod 61 such as a cylinder is provided.

The raw material cut through the grinder 50 is again supplied to the reverse conveyor 28. In the present invention, the reverse conveyor 28 is used in order to prevent a material such as a metal from flowing into the composite separator 30 in the raw material from the grinder. Referring to FIG. 5, the relatively large metal foreign material 102 is conveyed in the opposite direction from the composite separator 30 by the reverse conveyor 28. This large metal foreign object 102 is mostly for non-ferrous metals that are not filtered by the former magnetic separator. However, vinyls and plastics usable as raw materials are also conveyed in the opposite direction.

Therefore, in the present invention, a blower 55 is provided at the end of the reverse conveyor 28 to transfer a material that can be used as a raw material such as vinyls and plastics to the feed conveyor 29 to the composite separator 30. Since the process in the composite separator 30 is as described above.

Between the composite separator 16 and the molding machine 19 may further include a commutation feeder 17 for storing a final raw material, the supply of a predetermined amount to the molding machine 19.

However, the final raw material separated from the composite separator 16 is preferably passed through a dryer 17 which is dried using hot air or infrared rays to remove moisture, and then supplied to the metering feeder. Such a dryer 17 is sufficient to cover the conveyor that the final raw material discharged from the composite separator 16 is transported, and to supply a hot air or infrared rays inside the cover.

The metering feeder 18 stores raw materials in a storage space, and supplies a constant raw material in accordance with the processing capacity of the molding machine.

Finally, the final raw material supplied to the molding machine 19 is formed into a final RPF product by heat and compression force. 5 is a view showing the RPF produced in Figure 5 RPF manufacturing system according to the present invention. The final shape is 30mm in diameter and 100mm in height.

2 and 3 are flowcharts of a RPF manufacturing method according to the present invention.

In one embodiment of the RF manufacturing method according to the present invention, a crushing step of cutting the supplied raw material first, a magnetic separation step of removing metal foreign matter contained in the first cut raw material, specific gravity by using wind power Wind separation step of sorting the raw material smaller than the value of, and the crushing step of cutting the selected raw material secondly, separation to separate the final raw material by removing the foreign matter and metal foreign substances with a large specific gravity contained in the second cut raw material A step of forming an RPF by compressing the separated final raw material is possible, the RF manufacturing method is possible.

In this case, in the separating step, the foreign matter having a large specific gravity is removed using a distance that the wind power is applied to the raw material, and the metallic foreign substance is removed using a magnetic force.

Since this is similar to the configuration diagram of the device described above, a detailed description thereof will be omitted.

The present invention is not limited to the scope of the embodiments by the above embodiments, all having the technical spirit of the present invention can be seen to fall within the scope of the present invention, the present invention is the scope of the claims by the claims Note that is determined.
