Description

[0001] DIES FOR RPF FORMER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a molding die for an ALPE resin molding machine, and more particularly, to a molding die for an ALPE resin manufacturing molder using two heaters to increase heating efficiency, prevent breakage of the heater, and increase the convenience of replacement.

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.

Therefore, as a method for solving the problem of recycling of such resources, RDF (Refuse Derevied Fuel) which is made of solid fuel by treating flammable waste in household waste, and waste plastics are treated as solid fuel Many techniques have been disclosed for making refuse plastic fuel (RPF) made.

For example, Korean Patent No. 10-1001987 discloses such a molding apparatus.

In the past, the heater was located in the center of the molding die. In this case, since the molding die was tapered, the end portion where the heater enters and the outlet portion of the AFE had only 3 mm margin. Further, when there is a large amount of water in the waste in the rainy season or winter season, there is a problem that only one heater is not effective. Accordingly, in the present invention, the position of the heater is changed from the center to the side while increasing the number of the heaters, and the thickness between the receiving portion of the heater and the groove portion 22 can be increased. The present invention provides a new technology that can solve the problem that the heater is infiltrated in a large amount to shorten the life of the heater and the foreign matter is stuck to make the replacement of the heater difficult.

The present invention provides the following means for solving the above problems.

Sectional area of the molding die from the inflow portion 22a of the Arpef to the discharge portion 22b toward the discharge portion 22b of the molding die, in which a plurality of the molds are arranged adjacent to each other to form an ARPF fabrication molding machine, A body portion 21 provided so as to have a rectangular cross section; A groove portion 22 provided on both sides of the body portion 21 and contacting the adjacent molding die to form the extruded region; And a heater portion provided on the upper and lower surfaces of the body portion 21 and having a pair of heaters 40 respectively.

The heater unit includes a receiving groove 23 for receiving the heater 40 and a lid unit 24 for blocking the heater 40 built in the receiving groove 23 from the outside, 24 has a heater accommodating portion 25 formed to surround a part of the outer surface of the heater 40 and a groove 27 formed so that a power supply line for supplying power to the heater 40 is externally exposed, And a molding die for an AFFT molding machine.

A heat insulating material is provided inside the lid part 24 to block the heat generated in the heater 40 from flowing out to the outside through the lid part 24.

Wherein the body portion further includes a groove (26) for receiving the power supply line,

It is a molding die for ALFEV manufacturing molder.

In the present invention, the position of the heater is changed from the center to the side while the number of the heaters is increased to two, the thickness between the receiving portion of the heater and the groove portion 22 can be increased, It is possible to solve the problem that the heater is infiltrated to shorten the life of the heater and the foreign matter is staggered to make it difficult to replace the heater.

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.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 8 is a flow chart of the RPF manufacturing system to which the present invention is applied.

A crusher for firstly cutting the supplied raw material, a wind power separator for selecting the raw material cut by the wind by the specific gravity using wind power, a crusher for cutting the raw material selected by the wind power separator to a second order, And a molding machine for molding the RPF by compressing the final raw material separated from the composite separator.

Particularly, it is possible to further provide a crushing crusher for dissolving the unified portion of the raw material before the raw material is supplied to the crusher, and a magnetic separator for removing metallic foreign substances 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 carry out the crushing process using breaking and then transfer it 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, the magnetic separator may further include a magnetic separator for removing metal impurities downstream of the crusher, and a magnetic separator for removing metal foreign substances downstream of the wind separator.

The vinyl and waste plastics introduced into the crusher contain moisture, but the water contained therein is disadvantageous in that it 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 having been subjected to the above process is transferred to a wind power sorter. The wind power sorter is characterized in that the raw material is moved by wind power and only the raw material moved by a predetermined distance or more is selected.

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.

It is also possible to configure the wind-powered separator to supply the low-humidity warm air to remove the moisture contained in the plastic and the waste plastics. 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.

The raw material passing through the wind-powered sorter can be passed through a magnetic separator again. This is because metals with a relatively small volume can be buried in vinyl or the like and pass through a wind power sorter.

The raw material passing through the wind sorter is introduced into the crusher through the conveyor belt. The crusher is similar to the crusher and performs the function of cutting the raw material to a proper size. However, it is preferable to cut the waste vinyl so that the pulverizer has 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 crusher still contains metal foreign substances and the like. Therefore, it is finally separated by using a composite separator.

The composite separator can simultaneously perform the function of separating the raw material according to the specific gravity using the wind force and the function of separating the metallic foreign material using the 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.

9 and 10 are flowcharts of a method of manufacturing an RPF according to the present invention.

As an embodiment of the ALPEIF method, there is provided a method of manufacturing an ALPEIF, comprising: a crushing step of cutting the supplied raw material in a first order; a magnetic force selecting step of removing metallic foreign substances contained in the raw material cut by the primary; A separation step of separating the final raw materials by removing foreign matter and metal foreign substances having a large specific gravity contained in the raw material cut in the second order; And a molding step of compressing the separated final raw material to form the RPF.

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 that described above with reference to the configuration diagram of the system, detailed description will be omitted.

Hereinafter, the present invention will be described in detail with reference to FIG. 1 to FIG.

As described above, even if there are various sorting devices such as a wind power generator at the front end of the molding machine, some of the soil, glass powder, and the like which cause wear of the consumable material of the molding machine may enter into the molding machine.

Accordingly, the present invention provides a screen device capable of removing foreign substances such as earth and glass powder. The screen device of the present invention has the advantage of improving productivity and lifetime of consumable materials by replacing the bottom portion of the screw conveyor with a screen to remove foreign matter.

This screen device is a screen device provided in a screw conveyor (5) for supplying raw materials to a molding machine of an ARPEIF production system.

1 to 3, there are shown a charging unit 11 having a charging port 19 through which a raw material is charged from a conveying conveyor belt 3, a conveying unit for conveying the raw material to the molding machine, (18).

A plurality of holes (13) are formed in the lower part of the screw conveyor (5). This allows the foreign matter 101 such as earth and glass powder to be discharged to the outside of the screen. In order to further promote the discharge of these foreign substances, a vibration device 16 is further provided in the body part, and foreign matter such as soil or glass powder in the body part is discharged to the outside through the hole 13 So that vibration can be applied to the body portion. The body part itself according to the present invention is utilized as a screen device.

The hole 13 may be formed only in the charging part 11 of the body part and may extend to the conveying part 18. Foreign matter or the like may be separated from the raw material and accumulated in the conveying unit 18 even in the process of being conveyed according to the screw conveyor 5. The vibrating device can also be extended to the transfer part 18.

The raw material 100 is dropped from the conveying conveyor belt 3 to the screw conveyor 5. However, the raw materials 100 to be transferred are entangled with each other, and foreign substances such as soil and glass powder may be present in the raw materials which are entangled with each other.

The rod members may further include a plurality of rod members provided on the inside of the loading unit 11, and the rod members may be separated from the conveying conveyor belt 3 and the screw A plurality of first rod members 14 disposed between the conveyor 5 and spaced apart from each other by a predetermined distance and second rod members 15 provided between the first rod members 14 .

As shown in Figs. 1 and 2, the first rod member 14 and the second rod member 15 are provided in the longitudinal direction of the screw conveyor 5 while alternating with each other. Further, the first rod member 14 is provided at a higher position than the second rod member 15. The first rod member 14 separates the foreign material while dissolving the falling raw material, and the second rod member 15 dissociates the foreign material while separating the foreign material.

Through this process, the separated raw material is conveyed to the molding machine 20 while being compressed.

The molding machine is formed by disposing a plurality of molding dies in a circumferential direction so as to be in continuous contact as shown in Fig.

The raw material is supplied to the A region through the screw conveyor, and the raw material is discharged to the B region (outside) through the extrusion region formed between the molding dies, thereby forming the ARFEF.

In FIG. 4, although the A region is shown as opened for convenience of explanation, it is blocked by the casing from the outside, and the A region is a high pressure region through the screw conveyor.

Fig. 7 shows a state in which two molding dies are in contact with each other to form an extrusion region. A plurality of molding dies are disposed adjacent to each other to form an ALPEf production molding machine, and an extrusion area of ARPEFE is formed on the surfaces adjacent to each other.

Fig. 5 shows the appearance of a molding die.

The body portion 21 has a cross section that increases from the inlet 22a to the outlet 22b and has a rectangular cross section. The body portion 21 is provided on both sides of the body portion 21, A groove portion 22 contacting the molding die to form the extruded region and a heater portion provided on the upper and lower surfaces of the body portion 21 and each having a pair of heaters 40 embedded therein.

The point of the present invention is that a pair of heaters are used so that they can be symmetrical with each other. As shown in FIG. 6, the heater is inserted in two directions with respect to the groove portion 22 forming the extruded region.

In the past, the heater was located in the center of the molding die. In this case, since the molding die was tapered, the end portion where the heater enters and the outlet portion of the AFE had only 3 mm margin. Further, when there is a large amount of water in the waste in the rainy season or winter season, there is a problem that only one heater is not effective. Accordingly, the position of the heater is changed from the center to the side while increasing the number of the heaters, and the thickness between the receiving portion of the heater and the groove portion 22 can be increased, and a large amount of foreign matter penetrates into the heater- The life of the heater is shortened, and the problem that the foreign matter is stuck and the heater is difficult to replace can be solved.

In the present invention, the terms indicated by side, top, and bottom are based on FIG. 5, which may change if the direction of viewing is changed. Therefore, it should be understood that the upper surface and the lower surface mean the surface on which the groove 22 is not formed and connected thereto.

The heater unit includes a receiving groove 23 for receiving the heater 40 and a lid unit 24 for blocking the heater 40 built in the receiving groove 23 from the outside, A heater accommodating portion 25 formed to surround a part of the outer surface of the heater 40 and a power supply line (not shown) for supplying power to the heater 40 And a groove (27).

Still another feature of the present invention is to utilize the lid portion 24 to facilitate heater replacement.

A heat insulating material is provided in the lid part 24 so as to prevent heat generated in the heater 40 from flowing out to the outside through the lid part 24.

Generally, since the heater has a cylindrical shape with a circular cross section, the heater accommodating portion 25 and the accommodating groove 23 are aligned with each other to accurately form a space in which the heater is accommodated.

In addition, it is preferable that the body portion further includes a groove 26 for receiving the power supply line.

In the case of a molding die, in the process of passing through the heater while passing through the extrusion region, the unfired region is short, and the molded state of the formed AFF is maintained, but the process of transferring the molten state to the conveyor The molded state may be broken even if a slight impact is applied.

Therefore, it is also possible to provide the cooling member 30 as a means for increasing the non-heating period. That is, a plurality of molds are disposed adjacent to each other to form an extrusion molding machine for forming an extrusion area of an extrusion die on an adjacent surface, and the extrusion section of the extrusion die is formed from the extrusion section 22a to the extrusion section 22b (22) provided on both sides of the body portion (21) and forming the extruded region in contact with a neighboring molding die, and a groove portion And a cooling member 30 provided on the other surface of the body portion 21 and attached to the front end surface of the discharge portion 22b of the body portion 21, Can be provided.

It is preferable that the cooling member 30 has a rectangular cross-sectional area that increases in the opposite direction from the contact surface with the body portion.

In this case, a heat insulating material 31 is further provided between the cooling member 30 and the body portion 21 to prevent the heat of the body portion 21 from being transmitted to the cooling member 30 Do.

By further providing the cooling member 30, it is possible to increase the section where the cooling can be performed, and the density can be improved by the water, even if the impact is applied after discharging the ARPEEP, the forming state of ARPEIF can be maintained.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. .
