Conveyor screw of the combustion tube is integrally formed with a shaft of the motor, a shaftless screw extending from the shaft.

A conventional pyrolysis apparatus is illustrated in FIG. 1, in which the inside of the pyrolysis apparatus 111 operates integrally with the pyrolysis apparatus 111 while the central axis 120 passes through the center. The central shaft 120 is configured to allow the sliding material 132 and 134 to pass through the through portions 137 and 138 to slide along the through portions 137 and 138. At both ends of the removal devices 132 and 134, scrapers 133 and 135 are configured to be in close contact with the inner wall surface of the pyrolysis device 111.

The deposit removal device 132, 134 is installed perpendicular to the central axis 120, the inner wall surface of the pyrolysis device 111 forms a cylindrical shape of the same diameter around the central axis 120 from the inlet to the center. The cylindrical wall surface was gradually shortened in diameter while passing near the center portion. The scrapers 133 and 135 of the deposit removal device 132 and 134 only had the effect of removing the thermally decomposed waste plastic and the waste rubber by being in close contact with the inner wall surface of the pyrolysis device 111. And had no function of transferring waste rubber. Therefore, a small amount of waste plastic and waste rubber can be easily removed to discharge the waste plastic and waste rubber in an inclined direction. However, when there is a large amount of waste plastic and waste rubber, the adhesive removal device has no transfer capacity. Therefore, waste plastic and waste rubber were caught in the scraper, resulting in overloading of the motor. Therefore, the conventional pyrolysis device has a problem in that it can only thermally decompose 50 Kg of waste plastic and waste rubber per hour, which is not practical.

The present invention has been made to solve the above problems, the first object of the present invention is to protect the motor by preventing the overload of the motor, the second object of the invention is to thermally decompose a large amount of waste plastic and waste rubber It is to provide a pyrolysis device that can.

Waste plastic and waste rubber finely chopped through the hopper 12 of Sangkwang Strait is put into the input pipe 11, and the waste plastic and waste rubber presser 13 is put into the oil container 15 to oil and waste plastic and waste. After the rubber is mixed, the waste plastic and the waste rubber are transferred to the conveyor screw 17 installed in the conveying pipe 16 coupled to the oil container 15. The oil in the oil container 15 may seal the inside of the transfer pipe 16 from air, and smoothly reduce the friction of the inner wall of the transfer pipe 16 during transfer of the waste plastic and the waste rubber. . In the high pressure condenser 52, oil is supplied to the oil container 15 through the throttling valve T.

The conveyor screws 17 and 36 are driven by a motor M, and the shafts 17a and 36a for transmitting the rotational force of the motor are integrally formed with the shafts 17a and 36a. The rotational force is transmitted to the 36b. The shaftless screws 17b and 36b of the conveyor screws 17 and 36 are formed of a first screw member and a second screw member smaller than the first screw member. The screws 17b and 36b are welded to each other by welding a screw member made by winding a steel plate, and the screws 17b and 36b are manufactured by welding with the shafts 17a and 36a. Since the screws 17b and 36b are composed of two screw members, a large amount of waste plastic and waste rubber can be transferred.

The screw 17b of the conveyor screw 17 can smoothly transfer the waste plastic and the waste rubber along the conveying pipe 16 to prevent the overload of the motor M.

In addition, by using the gas extractor 18 disposed in the transfer pipe, the pressure inside the combustion pipe 34 is controlled by the pressure regulator 18a, and the gas extracted through the check valve C is sent to the primary cooler 50. . The check valve (C) blocks the inflow of the input of external air.

The waste plastic and waste rubber conveyed by the conveyor screw 17 of the transfer pipe 16 are administered to the combustion pipe 16 through the connection pipe 20. The oil burner 32 heats the combustion chamber 34, and the combustion chamber 34 transmits heat to the combustion housing 35 installed at the outer circumference of the combustion tube 34, thereby increasing the temperature of the inner wall of the combustion tube 34. Raise. A gas burner 33 is installed to effectively heat the combustion chamber 34 to quickly thermally decompose waste plastic and waste rubber.

Heat is transferred from the combustion housing 35 to the inner wall of the combustion tube 34 so that waste plastic and waste rubber are pyrolyzed. The internal temperature of the combustion tube 34 gradually increases from the inlet to the outlet, and the zone A of the combustion tube. At 150 ℃ to 250 ℃, the preheating and heating of waste plastic and waste rubber is carried out, and at zone B, it is heated to 250 ℃ to 400 ℃, and pyrolysis of waste plastic and waste rubber proceeds in earnest. Carbide is produced because the temperature is lowered from 300 to 300 ° C.

The motor M provided at one end of the combustion tube 34 drives the conveyor screw 36 for conveying the molten waste plastic and the waste rubber, and transports the upper portion of the combustion tube 34. The conveyor screw (36) has the same structure as the conveyor screw (36) installed in the transfer pipe (16) to transfer the waste plastic and waste rubber in the solid state, which is preheated and heated in the zone A, and in the zone B The gel pyrolyzed waste plastic and waste rubber are transferred, and the solid zone carbide is transferred in the C zone.

Carbide discharged through the discharge pipe 41 provided in the upper portion of the combustion pipe 34 is stored in the discharge container 44 via the gas tight plate 42 and the rotary valve 43 provided in the lower discharge pipe 41. do. The gas tight plate 42 blocks the inflow of external air.

In addition, the gas tight part 36 is installed on the outer periphery of the shaft 36a driven by the motor M in the combustion tube 34 so that the gas does not leak.

In the combustion pipe (34), the waste plastic and the waste rubber that enter the solid state become gaseous state through the phase transition to generate hot emulsion gas, and the generated hot emulsion gas is extracted from the combustion tube using a gas extractor and check valve (C). After passing through and cooled in the coolers 50 and 51, it is sent to the high pressure condenser 52 and the low pressure condenser 53 to make oil while condensing.

Since the heavy oil produced in the high temperature condenser 52 contains a lot of debris such as tar, it is re-supplied to the oil container 15 to be used as a sealing oil. When the oil having a large amount of residue is used for sealing, the residue of the sealing liquid is attached to the waste tire scrap continuously supplied, and thus, the oil is added to the combustion tube 34 again, thereby producing better oil through repeated pyrolysis.

The present invention by taking the configuration as described above, by reducing the friction of the inner wall of the transfer pipe and the waste plastic and waste rubber in the transfer pipe to facilitate the transfer of waste plastic and waste rubber to prevent the overload of the motor,

It facilitates the transfer of waste plastic and rubber which changes with phase transition in the combustion pipe and prevents overloading of the motor, while increasing the amount of tire pyrolysis to 1.5 tons, which has been increased from 50 kg per hour to 1.5 tons. .
