Abstract

PURPOSE: A device is provided to divide and extract a copper line without a cause of environmental pollution, which is not oxidized and has a good tension by extracting a synthetic resin generated in a process of melting and carbonizing a waste electric wire and slightly beating the bundle of the carbonized electric wires. CONSTITUTION: Discharging pipes(2,2') of incinerators(1,1') are connected to a chamber(4) of re-combustion installed with an oil burner(3), and carbonizing tanks(7,7') formed with discharging pipes(6,6') are installed on the lower side in a heating furnace(5). In addition, gas discharging pipes(8,8') are connected to the chamber of re-combustion by communicating with a gas pipe(9) on a side face, and a heat decomposing chamber(12) installed with the oil burner is connected with a cyclone(13) in a discharging hole(10). Herein, a washing top(14) is installed on the upper side.

Description

A device that separates synthetic resin and copper wire by melting and dry carbonizing waste wire.

The present invention relates to an apparatus for separating and extracting synthetic resin and copper wire by melting and drying carbonized waste wires, and indirect heat of an incinerator to carbonize the waste wires in the distillation tank without carbon pollution to extract copper wires. .

Conventionally, when copper wires are separated to recycle waste wires, they are burned by incineration, so harmful poisonous gases and odors, black fumes and dioxin, which are heavy metals, are polluting the atmosphere, causing environmental pollution. There was a difficulty in recycling copper wire due to the deterioration of purity due to oxidization in Si, and the loss of synthetic resin, which is a valuable resource, was lost.

The present invention is a synthetic resin produced in the process of melting and dry distillation carbonization of the waste wire inflow through the reburn chamber and around the distillation tank using the indirect heat of the waste incinerator in order to solve the above-described waste incineration into the filter cylinder. When the waste wire is removed and lightly punched, it is possible to separate out the copper wire having good tensile strength without oxidation without pollution.

Connect the discharge pipes (2) and (2 ') of the incinerator (1) and (1') to the reburn chamber (4) equipped with the oil burner (3) and discharge pipe (6) to the lower side inside the heated furnace (5). A dry distillation tank (7) (7 ') having a 6' formed thereon is connected to the reburn chamber (4) by connecting gas discharge pipes (8) and (8 ') to the gas pipe (9) on the side. The pyrolysis chamber 12 and the cyclone 13, which is equipped with an oil burner 11, are opened, but the washing tower 14 is installed on the upper side thereof.

Unexplained symbol '15' indicates an on-off valve, '16' indicates a ladder, and '17' indicates a relocation exit.

In the present invention, the waste wires cut into the filtration cylinder (not shown) using a hoist are added to the distillation tanks 7 and 7 'of the heating furnace 1, and the incinerator 1 and 1' are sealed. When high heat is discharged into the discharge pipe (2) (2 '), it enters into the heating furnace (5) via the reburn chamber (4) equipped with the oil burner (3), and the dry tank (7) (7') is opened. When heated to 180 ° C to 250 ° C, the synthetic resin of the waste wire is melted by indirect heat and flows out to the discharge pipes 6 and 6 'below the distillation tanks 7 and 7' and the distillation tanks 7 and 7 '. The gas generated while the synthetic resin is melted is introduced into the reburn chamber 4 through the gas discharge pipes 8 and 8 'and the gas pipes 9 on the side and reburned by the oil burner 3 to heat the furnace 5 As it enters into), the synthetic resin of some unmelted waste wire is carbonized, and the remaining heat is discharged into the pyrolysis chamber 12 through the outlet 10 and the unburned toxic gas is transferred to the oil burner 11. When recombustion is dissolved and introduced into the cyclone 13, dust and turbid air, which are pollutants in the upper washing tower 14, are removed and exhausted, and the distillation tanks 7 and 7 'are simultaneously removed. The dry carbonized waste wire is removed from the hoist and lightly blown, and the carbonized synthetic resin is removed from the copper line.

In the present invention, waste wires coated with synthetic resin are indirectly heated waste wires in the distillation tanks 7 and 7 'by the heat of the waste incinerator, and molten synthetic resins are collected and collected separately, and the remaining synthetic resins are dried by carbonizing and drying. Without this, there is an effect that can separate the copper wire with good purity and tensile strength.
