It is about.

Currently, plastics and vinyl, which are polymer materials composed of hydrocarbons used for various purposes, have increased emissions due to industrial development, and most of them are disposed of by incineration and landfill, causing serious environmental pollution such as air, soil, and ocean. As a result, new treatment technology for polymer waste is required.

In addition, due to the recent increase in oil prices, various measures for the cyclical use of resources have been devised, and thus, an emulsifying apparatus technology for recycling various types of waste plastics has been activated. For example, by recycling waste plastics, such as waste plastics and vinyl, made from petroleum as raw materials, heat is applied in a reducing atmosphere without oxygen to cause decomposition reactions in which the carbon chain constituting the polymers is broken and changed into several low molecular materials. As the waste is dissolved, it is vaporized and then liquefied through a cooling device to obtain refined oil again. Some hydrocarbons break their bonds even at 200 ° C, and violent pyrolysis occurs when heated to 350-400 ° C.

Such an emulsifying apparatus has a batch type in which waste is heated and melted from the outside in a state in which the waste is charged in a pyrolysis furnace, and a continuous type in which waste is continuously fed into the pyrolysis furnace and continuously pyrolyzed while heating from the outside.

Referring to FIG. 1 as a related art related thereto, Patent Document 1 discloses a horizontally rotated by a rotational force provided by a motor 13 and stirs a solvent and a solvent by a spiral 11 formed on an inner circumferential surface of waste plastic and waste vinyl. And a separator 20 for separating gas discharged from the discharge pipe 12 connected to the outlet side of the furnace 10 into heavy oil gas and diesel gas, and the separator 20 for heating by heating. A cooling device 30 for cooling and liquefying the gas oil separated by the gas, a gas storage part 40 for storing and liquefying gas and gas oil cooled by the cooling device, and a gas not liquefied by the gas storage part. A gas supply unit 50 for resupply to the heating furnace, a combustion gas outlet 60 for discharging the combustion gas of the waste to the outside of the heating furnace 10, and a dust collector for separating and collecting fine characters included in the combustion gas ( 70 and the combustion that has passed through the dust collector 70 There is a waste plastic and general waste plastic painting apparatus is disclosed that includes an exhaust fan 80 for discharging to the outside.

However, in the above-described emulsification apparatus of the prior art, oxygen may be introduced into the heating furnace through the input pipe in the process of injecting the polymer waste, and in this case, the safety of the large-scale safety that the operation of the device is stopped or the oxygen and the vapor react with the explosion An accident can occur.

In particular, domestic garbage and marine wastes contain a lot of foreign substances such as iron, non-ferrous metals, glass, etc., because they have a lot of moisture and it is difficult to accurately sort them. Due to the nature of being formed or aggregated, if the transfer is not smooth and waste residues accumulate in the input pipe, or the parts are worn or broken down, the pyrolysis furnace and the input pipe are hardly separated and the operator maintains the equipment by stopping the operation. And hassle and inconvenience of having to reassemble after hard work.

It can be manufactured in a small size, compact design of continuous pyrolysis emulsifier, and cost is reduced.

At this time, the heating means 250 may be formed below the pyrolysis furnace 200 to heat the pyrolysis furnace 200. Configuration and operation for the rotation and heating of the pyrolysis furnace 200 of the above-described configuration is already known in the art, so a detailed description thereof will be omitted here.

The pyrolysis furnace 200 is the discharge pipe 300 is connected to the discharge port on the other side, the horizontal line of the gas discharge pipe 400 and the sludge discharge pipe 500 is passed through the inside of the discharge pipe 300 and the oil vapor gas and The sludge is separated and discharged separately.

Referring to FIG. 3, the injecting means 100 is connected to a raw material supply means 90 such as a hopper to receive polymer waste and to inject it into the pyrolysis furnace 200, and to be injected into one side of the pyrolysis furnace 200. Pipe 110 is connected, as shown in Figure 4a a pair of injection screw 120 inside the injection pipe 110 is installed side by side up and down rotatably by the drive means 122 is a polymer waste pyrolysis furnace 200 Squeezed to the inlet side of the transfer, the pair of injection screw 120 is disposed so as to overlap with each other while being spaced apart with a slit 130 is a narrow gap therebetween.

A wing groove is formed, and the wing feathers 121a of the upper injection screw are disposed so as to overlap each other so as to be nearly engaged with the wing grooves of the lower injection screw, thereby minimizing the inflow of air, such as oxygen, and the polymer. By pressing and transporting the waste into the pyrolysis furnace, the waste can be transported and injected smoothly without stagnation, the amount of polymer waste can be easily adjusted, and the waste input efficiency is increased. However, the pair of input screws 120 are not in contact with each other, a slit 130 formed of a narrow gap therebetween is formed.

When viewed from the side, the slit 130 is formed in a shape in which a wave shape such as "-" is repeatedly connected, and mainly thin waste vinyl is compressed and transported through the slit 130, and the thickness thereof is 2 to 10 mm. It is preferable to consist of a narrow gap.
