Description

The junk plastic fusion and adulterate selection device whose remaking is impossible

The present invention relates to a device for melting non-recyclable waste plastics and sorting out contaminants. More particularly, the present invention relates to a non-recyclable waste plastic in which a non-recyclable waste plastic is mixed with a foreign material. The present invention relates to a non-recyclable waste plastic solid fuel combustion burner structure capable of preventing economic pollution as well as improving economic efficiency by selecting plastics and foreign substances at the same time as combustion is generated by alternative fuels.

As is generally known, in modern society, the environment is often damaged by pollution due to materials, and in particular, products using synthetic resins or rubber materials, which are generated due to industrial development, are overflowing, but these wastes are decomposed in the natural state. It does not take much time to disintegrate or decompose, which is the main cause of serious environmental pollution.

Therefore, many researches have been made due to social problems in disposing the industrial wastes. However, since the profitability of the domestic waste treatment facilities does not match, it has been left or landfilled in certain areas.

Incineration is known as a method for treating such wastes, but in this case, harmful gases are generated during incineration, which causes air pollution. It is expensive and the cost of combustion is not small, which is economically and environmentally undesirable.

In addition, there are some known methods of treating such wastes in the form of solid fuels, and in this case, the solidification through waste sorting, drying, mixing, and compacting is mainly used. The solid fuel thus obtained is not only difficult to solidify the fuel, but the solid fuel is a method of treatment that is close to direct combustion, which requires a lot of energy to burn and generates a lot of harmful gases during combustion. As the problem becomes serious, a separate countermeasure must be established to solve this problem, and accordingly, it is difficult to put into practical use and thus it is not actually applied.

In addition, there is also known a technique for dry distillation of waste, in this case, both direct combustion and indirect combustion methods are known, but all of them are not solved fundamentally because the problem of incomplete incombustible gas generated during dry distillation and combustion is not solved fundamentally. Pollution problems inevitably occur, and there is a problem in that the efficiency of using waste heat generated in the treatment is low and economical, and the consumption of energy in the treatment is relatively large.

In addition, conventionally, waste plastics are sorted and sold as high-quality plastics that can be earned by business operators. However, non-recyclable waste plastics, which are not profitable, are difficult to be recycled. There is a lot of trouble and economic burden to deal with.

Therefore, the present invention has been made to solve the above problems, the non-renewable waste plastics are mixed with foreign matter to minimize the volume in the 1st and 2nd generation of heat energy of the gel (gel) of alternative energy sources and products The purpose of the present invention is to provide a device for sorting and recycling non-recyclable waste plastics that can prevent environmental pollution as well as maximize economic efficiency by recycling resources.

The present invention for achieving the above object is a secondary melter to reduce and preheat the volume of the non-recyclable waste plastic in which foreign matter is mixed with high-pressure steam generated in the steam boiler, and the waste plastic preheated in the auxiliary melter is melted The melter is melted with a gas is formed into a screw inside the body to transport the waste plastic is introduced into the main body through the hopper, and a thermal power generator for applying heat to the waste plastic to be transported to the lower part of the main body is formed An auxiliary cover is formed on the outer surface of the main body so as to constantly maintain the high temperature heat generated from the thermal power generator, and an expansion coefficient adjusting groove is formed on the inner and outer surfaces of the auxiliary cover and ends the main body. While transported to the cross section, a plurality of liquid fuels are discharged by heat. It is to provide a non-recyclable waste plastic melting and contaminant sorting device characterized in that the discharge hole is formed.

As described above, the present invention is a waste plastic that is not regenerated mixed with foreign matter is maintained by the constant temperature and constant heat by the steam boiler is formed inside the main body and the auxiliary cover and the thermal power generator formed outside the body waste As the plastic melts, an alternative fuel in the form of a gel is generated, so that the waste plastic is reproduced as fuel instead of being landfilled, which is environmentally friendly and can increase energy resources, thereby maximizing resource efficiency.

On the other hand, when the waste plastic 100 according to the present invention is put into the melter 1 in order to fuel, the waste plastic 100 connected to the melter 1 is introduced into the hopper 22 is 60 ℃ ~ An auxiliary melter 7 is formed which can maintain an appropriate temperature of about 70 ° C.

The auxiliary melter (7) is a hopper (1) of the main body (2) to the first conveyer 71, the waste plastic 100 is connected to the first conveyer 71 by a connecting cylinder (73) to be conveyed It is formed as a second feeder (72) formed with a connecting pipe (72a) to be introduced into the 22.

Inside the first conveyor 71 and the second conveyor 72, each screw 74 is formed to rotate in accordance with the drive of the drive motor 400 to transfer the waste plastic 100 is formed. .

In addition, around the outer surface of the first feeder 71 and the second feeder 72 of the auxiliary melter 7 is formed with a steam supply tube 10 connected to the steam boiler 5 by a steam pipe 52. It is done.

A plurality of diaphragms 11 are formed in the steam supply cylinder 10 so as to cross different lengths, but the long diaphragm 11 allows the steam to circulate smoothly in the steam supply cylinder 10. A steam circulation hole 12 is formed.

In this case, the steam boiler 5 connected to the steam supply cylinder 10 is the same as the steam boiler 5 connected to the heat supply cylinder 9 of the melter 21.

Reference numeral 91 in the accompanying drawings is a year that is connected to the heat supply cylinder 9, 300 is a support for supporting the melter (1).

Looking at the effect of the present invention made of the above configuration as follows.

First, the waste plastic 100 mixed with non-renewable foreign matter is introduced into the first feeder 71 and the second feeder 72 of the auxiliary melter 7 and transferred by the screw 74. The first conveyer 71 and the second conveyer 72 of the auxiliary melter 7 are conveyed to the first conveyer while the high pressure steam generated in the steam boiler 5 is circulated in the steam supply vessel 10. Drive motor 400 while transferring the heat into the machine 71 and the second feeder 72 to maintain a temperature of approximately 60 ℃ to 70 ℃ inside the first feeder 71 and the second feeder (72) It is conveyed by each screw 74 that is to be rotated in accordance with the drive of the), the waste plastic 100 is the second conveyer 72 of the melter 1 through the connecting pipe (72a) It is to be injected into the body (2).

At this time, the volume of the waste plastic 100 is reduced and preheated by the auxiliary melter 7, so that the waste plastic 100 can be easily melted in the melter 1.

Therefore, since the waste plastic 100 is bulky, if it is continuously and quantitatively injected into the auxiliary melter 7, the waste plastic 100 is shrunk and the temperature rises to 70 ° C. or more, more easily in the melter 21. To make it melt.

As such, the waste plastic 100 introduced into the melting chamber 21 is transferred in accordance with the rotation of the screw 23 which is rotated by the driving of the driving motor 400. In this case, the thermal power generator 4 The generated high temperature heat is transferred to the melting chamber 21 inside the main body 2 so that the waste plastic 100 is gelled.

When the heat of the thermal power generator 4 is transferred into the melting chamber 21, the melter 1 is formed as a double tube by the auxiliary cover 6 formed on the outer surface of the main body 2 so that the main body by direct heat ( 2) It can also protect the interior and slow down the temperature change of the rapid or descent, it is also possible to block the heat of the high temperature it is possible to suppress the gasification caused by the high temperature when melting the waste plastic 100.

In addition, since the melter 1 according to the present invention is formed as a double tube of the main body 2 and the auxiliary cover 6, the energy loss in the melting chamber 21 can be continuously compensated for.

In addition, since the heat conduction plate 3 is formed on the outer surface of the main body 2, the heat conduction plate 3 is supplied with the temperature by the direct heat to the auxiliary cover 6 and the main body 2, and The energy lost in the main body 2 will be continuously supplied to the auxiliary cover 6 and the main body 2.

Thus, the temperature of the heat conduction plate 3 is a thermal conductivity of about ± 500 ℃ on both sides, the temperature heat transfer and storage of the auxiliary cover 6 is to be able to maintain about ± 400 ℃.

In addition, the present invention is a double tube of the main body 2 and the auxiliary cover 6, so that there is a gap between the main body 2 is to maintain ± 280 ℃ ~ 300 ℃.

Therefore, the heat conduction plate 3 and the auxiliary cover 6 are continuously replenished as much as the heat loss consumed by the main body 2 to maintain a constant temperature inside the main body 2.

Meanwhile, the melter 1 according to the present invention should supply the temperature of the thermal power generator 4 to a temperature of about 500 ° C. to the main body 2, but when the temperature in the melting chamber 21 is lowered, the melting chamber ( The fuel supply should be added to 21). On the contrary, if the temperature of the main body 2 is higher than about 500 ° C, the fuel supply should be reduced.

At this time, the temperature inside the melting chamber 21 can be adjusted within a predetermined range of about 500 ° C. while supplying the energy consumed in the main body 2 appropriately. The temperature may be increased in 4). However, when the temperature in the main body 2 exceeds the range of 500 ° C. to 600 ° C., the temperature does not immediately decrease even if the fuel supply to the thermal power generator 4 is reduced. .

As such, when the internal temperature of the melting chamber 21 of the main body 2 becomes high beyond a predetermined range, the high pressure steam generated by the steam boiler 5 temporarily moves the steam nozzle 51 through the steam pipe 51. Since the internal temperature of the melting chamber 21 can be easily adjusted to an appropriate range by being diverted to the heat supply cylinder 9, the gasification of the waste plastic 100 can be normalized by immediately blocking the gasification caused by melting. Will be.

Along with this, the inside of the melting chamber 21 of the melter 1 is melted due to the high temperature heat of the thermal power generator 4 and the compressive force of the waste plastic 100 which is fed into the melting chamber 21 and transported. As the gas, moisture, and air are strongly compressed therein, the expansion coefficient is increased, thereby being discharged to the expansion coefficient reduction port 8 through the through hole 26 of the main body 2, and simultaneously pressing the expansion coefficient reduction port 8. It is discharged to the discharge pipe 82 through the air discharge hole 81, the gas discharged to the discharge pipe 82 is to be burned by the heat of the thermal power generator (4).

Thus, as the waste plastic 100 is in a gel state by the operation of the melter 1 according to the present invention, the waste plastic 100 is discharged through the discharge hole 24 of the main body 2 to be used as an alternative fuel.

As such, the waste plastic 100 preheated in the auxiliary melter 7 and introduced into the vessel 21 is melted in a gel state in the molten chamber and transferred to the rear end of the melting chamber 21. The compressed fuel is compressed at the rear end compression point of the main body 2 to discharge the alternative fuel in a gel state into the discharge hole 24 of the main body 2.

In addition, the contaminants 200, such as bottle caps, cotton types, papers, and gold foils, which are not melted in the melting chamber 21, are melted while being continuously compressed into the contaminant outlet 25, which is an open end portion of the main body 2. The waste plastic 100 is to be selectively discharged.

At this time, when the waste plastic 100 is introduced into the melting chamber 21 inside the main body 2 through the hopper 22 and the waste plastic 100 is liquefied by high heat by the thermal power generator 4. The waste fuel 100 is rotated by the screw 23 so that a large amount of the waste plastic 100 is transferred to each other with high compressive force, so that the alternative fuel generated in a gel state is smoothly discharged to the outside through the discharge hole 24. Will be discharged.

In addition, since the temperature sensor 27 is provided in the melting chamber 21, the temperature of the inside of the melting chamber 21 is sensed so that the heating temperature of the melting chamber 21 drops or becomes high (not shown). By controlling this, the thermal power of the thermal power generator 4 or the steam of the steam boiler 5 will be adjusted so that the temperature inside the melting chamber 21 can be kept constant.

Therefore, the melter 1 and the auxiliary melter 7 according to the present invention are transferred from the melting chamber 21 to the screw 23 using the waste plastic 100 which cannot be recycled, and thus, the gel is heated at a high temperature. Since the non-recyclable waste plastics 100 are recycled with high value-added fuels without being landfilled as in the prior art, it is possible to solve the problem of the treatment of waste plastics that pays and treats waste disposal costs. Of course, the fuel economy can be reproduced by reproducing.

The present invention is not limited to the above-mentioned specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Such changes are intended to fall within the scope of the claims.
