Conventional waste plastic carbonization equipment that carbonizes waste plastics with the carbonization kettle installed in the carbonization furnace stops the carbonization furnace and cools the carbonization kettle after one cycle of carbonization is completed, and the carbonization kettle returns to a predetermined temperature. After cooling down to a certain temperature, a worker enters the kettle and removes the residue.Then, the raw material waste plastic is put into the kettle, and the carbonization furnace is heated again to carbonize the waste plastic.

Furthermore, each time a single carbonization process is completed, a worker must enter the vessel to remove the residue, which is dangerous and considered hard labor.

The present invention involves installing a carbonization vessel with a residue discharge port at the bottom in a carbonization furnace, and installing a stirring blade that rotates around a vertical axis of rotation in the carbonization vessel close to the bottom of the carbonization vessel. A discharge opening/closing device is installed below the carbonization pot to open and close the residue discharge port provided at the bottom of the pot. This continuous feeding type waste plastic carbonization apparatus is characterized in that it is configured to carry out carbonization while stirring with a stirring blade, and to discharge the residue remaining in the carbonization pot from a residue discharge port by rotating the stirring blade in the opposite direction. .

A stirring blade built into the carbonization tank rotates at low speed close to the inner circumference of the bottom of the carbonization tank, and the waste plastic turned into soft sludge by the extruder is continuously fed into the carbonization tank in a state where air is blocked. The plastic waste in the form of soft mud is heated and becomes molten plastic. Since this molten plastic is stirred by a stirring blade, carbonization is promoted.

に、残滓物が排出口から自動的に押出される。 When the stirring blades are rotated in the reverse direction at a low speed and the residue discharge port provided at the bottom of the carbonization vessel is opened using the discharge port opening/closing device, the stirring blade provided close to the inner periphery of the carbonization vessel is removed. The blade functions as a scraper, and the action of the stirring blade removes the residue adhering to the inner periphery of the carbonization vessel, and at the same time, the residue is automatically pushed out from the discharge port.

留炉の熱効率の双方が著しく向上する。 In this way, it is possible to perform the tasks of inputting waste plastic, which is a raw material, and discharging the residue, while the carbonization pot remains installed in the carbonization furnace.Moreover, the operation of the stirring blade allows the waste plastic to be stored in the carbonization pot. Since the molten plastic is stirred, both the carbonization efficiency and the thermal efficiency of the carbonization furnace are significantly improved.

In this invention, a stirring blade that rotates around a vertical rotation axis is installed in the carbonization tank close to the bottom of the carbonization tank, and the discharge port is opened and closed to open and close the residue discharge port provided at the bottom of the carbonization tank. Since the device is installed below the carbonization tank, waste plastics in the form of soft slurry can be continuously carbonized by feeding into the carbonization tank while the carbonization tank remains installed in the carbonization tank, and the residue remaining in the carbonization tank can be continuously carbonized. You can eject things. Furthermore, since the molten plastic contained in the pot body is carbonized while being stirred by the stirring blade, the carbonization efficiency is significantly improved.

In addition, the molten plastic contained in the carbonization tank is stirred by the action of the stirring blade, so both the carbonization efficiency and the thermal efficiency of the carbonization furnace are significantly improved. .
