However, in the former case, only the input part is a double screw, but the input is good, but in the single screw part, a bottleneck occurs and the machine breaks down due to unmelted resin pressure. As a result, incomplete melting of the resin material caused a secondary melting and extrusion process.

Therefore, in the treatment of waste synthetic resins with different physical properties, they are melted and pressurized without burning, and the amount of waste gas generated during melting of the waste synthetic resin is reduced, and the exhaust gas generated during the melting and pressurization process is used as a reheating heat source of the screw conveyor. After that, it is filtered in the filtering chemicals, and the recycled resin can be recycled by processing a predetermined recycled product as the final discharged regenerated material, and it is possible to substitute and install it by field power such as a tiller instead of a driving motor. There is a need for a waste synthetic resin recycling apparatus that is easy to process.

The present invention has been made in view of the above problems of waste synthetic resin processing apparatuses such as conventional waste synthetic resin extruders, and a heated screw conveyor as a heating rotary body surrounding the screw conveyor is softened by melting and pressure without a combustion process. It is an object of the present invention to provide a waste synthetic resin recycling apparatus for kneading.

The present invention also provides a purifier for removing harmful substances through a predetermined purifier while reusing waste gas generated during the softening and kneading of the waste synthetic resin as a heat source of a screw conveyor.

The present invention also provides a waste synthetic resin recycling system equipped with a regeneration apparatus that enables processing of various blocks and other regenerated products as predetermined discharges in addition to the melting, pressurizing and purifying functions.

Another object of the present invention is to provide a mobile device capable of moving to a waste synthetic resin loading position for installation and operation of the waste synthetic resin recycling apparatus.

The present invention ultimately melts and pressurizes the supplied waste synthetic resin between the heated screw conveyor and the rotating body to obtain a predetermined recycled product, and the waste gas generated in this process can be almost purified to a small amount. It is a main object to provide a waste synthetic resin recycling apparatus which is mixed with a predetermined material and applied as a raw material for processing a molded article such as a block by vibrating or pressing.

It is possible by doing.

As shown in FIGS. 1 and 4, the rotational structure for the overlapping rotation in different directions is based on the inlet portion 21 and the rotation of the screw conveyor 20 using the drive motor 71 as a power source. It is possible by distributing and transmitting power to the rotating means 13 of the whole 10, respectively.

The power transmission means 70 for distributing and transmitting this power outputs suitable power as the drive motor 71 and the speed reducer 72 which are transmitted as belts 78 to each other. The sprocket 77 is provided in this reducer 72. Accordingly, the first chain 74 is connected between one of the plurality of sprockets 73 of the inlet portion 21 of the screw conveyor 20 and the sprocket 77 to transmit rotational force, and at the same time, the rotary body 10 The power is distributed by connecting the second chain 76 between one of the plurality of sprockets 73 and the driven sprockets 75. The driven sprocket 75 is provided with a rotating shaft 15 between the sprockets 14 of the rotating body 10. Therefore, the screw conveyor 20 is driven by the screw sprocket 20 connected at a predetermined ratio in the output sprocket 77 of the speed reducer 72 and the driven sprocket 75 connected at a predetermined ratio between the conveyor 20 and the screw conveyor 20. And the rotating body 10 are rotated in opposite directions at a predetermined speed. In such a rotational structure, the reverse rotation by the speed reducer 72 is also possible. Sometimes, when the melted state of the waste synthetic resin located in the screw grooves 24 between the screws 23 is not good, it is necessary to adjust the melted state by rotating the reducer 72 in reverse.

The combustion gas pipe 52 is opened to ignite the gas burner 51 in the combustion chamber 53. Subsequently, when a predetermined temperature is detected as the temperature sensor 54, the waste gas pumping means 63 and the purifier 80 pumping means 84 are operated. At the same time, driving the drive motor 71 of the power transmission means 70 to rotate the screw conveyor 20 and the rotating body (10).

As such, when each operation of the rotation, combustion, and pumping of the present invention is started, waste synthetic resins are introduced into the inlet 31. When the waste synthetic resin is added, the waste synthetic resin is increased or decreased by artificially adjusting the thermal power by a temperature gauge (not shown) installed for each part. When the discharged melt regenerated product is abnormally discharged, the kneading is repeated while rotating the driving motor 71 of the power generating means 70 in reverse. When the discharge of the contents is started, the predetermined molding machine 100 obtains a regenerated product according to a predetermined mold through a molding machine which has undergone a process of vibration and compression after mixing the separate compounding material and the regenerated product of the present invention.

Fourth, the screw conveyor heating takes the combustion method by LPG gas, not electricity, and collects the first high temperature combustion gas in the casing, and then reheats the waste gas obtained during the compression and melting process through the combustion chamber to produce the second high temperature gas. Obtain a heating effect of the conveyor without a separate heating means by heating the screw conveyor with the primary high temperature gas. This heating effect not only simplifies the structure of the screw conveyor and the rotor, but also reduces the waste of thermal energy.

Fifth, it is possible to reduce the generation of waste gas during the melting and pressurizing process by obtaining a predetermined recycled product by melting and pressurizing without directly burning the waste synthetic resin through the melting and pressing process, and furthermore, by repeatedly reheating a small amount of waste gas. It almost eliminates harmful components, and in particular, it removes the first harmful component and then purifies it again with the filtration structure of the above-described components, thereby removing all the non-polar and polar gas odors remaining in the waste gas. There is an effect that greatly improved the problem of air pollution by the field.

Sixth, by using LPG gas as the heating raw material, the opening and closing control according to the temperature control is easy, and it can be used in the place without power, which makes it easy to install the vehicle or use the waste synthetic resin treatment plant in the open air.

Seventh, it is possible to use the cultivator motor instead of the power motor to be moved to the waste synthetic resin loading position is not fixed in one place to improve the problems caused by the conventional waste synthetic resin transport.

Eighth, the present invention eventually reduces the generation of waste gas while melting and compressing the synthetic resin, and at the same time, forming a block or the like mainly based on a large number of waste synthetic resins recognized by mixing and extruding it as a discharge material obtained in such a process. The effect is that processing is made possible by one waste synthetic resin system.

As described above, the present invention improves the recycling rate of the waste synthetic resin by recycling the waste synthetic resin into processing materials such as various block structures while improving the problem of combustion gas generated by various apparatuses according to the conventional waste synthetic resin treatment.
