The main furnace body 11 includes an inner furnace 12 and an outer furnace 13. A cracking reaction chamber 121 is formed inside the inner furnace 12. An oil output pipe 17 is provided at the upper part of the cracking reaction chamber 121. A heating space 131 is provided between the inner furnace 12 and the outer furnace 13. One end of the heating space 131 has an air inlet 132, and the other end has an air outlet 133;

The feeding device 14 is a feeding pipe 141 extending from one end thereof through the outer furnace 13 to the cracking reaction chamber 121 of the inner furnace 12, and the feeding pipe 141 has a feeder 142 therein, which can transport the external waste plastic from the feed inlet 122 into the cracking reaction chamber 121 for heating and cracking reaction;

One end of the heating device 15 is connected to the air inlet 132, and can supply hot air to the heating space 131;

The distillation device 16 is arranged at one end of the oil output pipe 17, and discharges the oil smoke in the cracking reaction chamber 121 through the oil output pipe 17, and uses a distillation method to distill the oil smoke into oil (diesel, gasoline), thereby achieving the purpose of distilling waste plastics and recovering oil.

Although the waste slag generated by the heating and cracking reaction of waste plastics in the above-mentioned known oil-refining reactor can be discharged (cleaned) by opening the slag discharge port 123 at the bottom of the cracking reaction chamber 121 when the waste slag accumulates to a certain extent, the slag discharge and cleaning work must be completed by manpower; the new patent case of the Republic of China Certificate No. M581670 created before this case can achieve automatic slag discharge However, if the slag is not discharged after it is completely cooled (because it takes a long time for the slag in the furnace to be completely cooled, which will affect the timeliness of the waste plastic cracking reaction process), there is a high risk of public security incidents during the temporary storage period when the high-temperature slag is discharged and waits for cooling before being processed. In addition, it is also a waste or loss of energy (heat energy).

The main purpose of this invention is to provide a slag conveying structure for an oil-making reactor, which is a reactor, including a main furnace body, a feeding device, a stirrer, a heating device, a distillation device, a slag discharge valve and a slag conveying device;

When the waste slag remaining after the waste plastic is heated and cracked in the cracking reaction chamber accumulates to a certain extent, the waste plastic is stopped from being fed into the cracking reaction chamber and the hot air from the heating space is stopped. The waste slag in the cracking reaction chamber can be discharged from the slag discharge port under the stirring of the agitator. The waste slag is discharged and enters the slag delivery pipe of the slag delivery device along the slag discharge pipe, and is pushed by the slag delivery device, and then sent to the temporary storage bin for treatment from the slag delivery end of the slag delivery pipe; in the process of the slag delivery device pushing the waste slag, the residual waste heat of the waste slag is absorbed by the pipe wall of the slag delivery pipe, and the cold water is sent into the water chamber through the water inlet of the tubular water tank to produce a heat exchange effect with the pipe wall of the slag delivery pipe, and warm water/hot water is taken out from the water outlet; the waste slag can be quickly cooled by the process of being pushed by the slag delivery device, so that the process safety is improved when the waste slag is sent to the temporary storage bin for temporary storage, and the warm water/hot water taken out from the water outlet of the tubular water tank can be used, and the waste slag waste heat can also obtain the economic benefit of heat energy recovery.
