The present invention relates to a debris removal device of a waste synthetic resin recycling system.

In general, various products that use synthetic resin as a main raw material are disposed of in landfills, which are social infrastructures, or incinerated at incineration plants.

However, wastes containing synthetic resins (hereinafter referred to as "waste synthetic resins") are not decomposed naturally, so when the waste synthetic resins are landfilled, they not only degrade the soil, but also mix with other pollutants in the event of rainy weather. There is a problem that flows into the water pollution.

In the case of incineration of waste synthetic resins, there is a problem of polluting the air due to the emission of various heavy metals and the generation of toxic gases. In particular, such water and air pollution not only destroys the natural environment but also adversely affects the human body. There is a serious problem.

The extrusion cylinder 121 has a hollow tubular shape in which the inlet 121a through which waste synthetic resin is introduced and the outlet 121b through which molten molten resin is discharged are formed at both sides in the longitudinal direction.

The inlet 121a of the extrusion cylinder 120 is connected to the outlet of the hopper 111 of the material input part 110, and the foreign material removing device 130 is coupled to the outlet 121b.

In addition, the melt heater 123 is installed to surround the extrusion cylinder 121, and generates heat by power supplied from a power supply unit (not shown), thereby preheating the inside of the extrusion cylinder 121 at the time of initial operation of the system 100, thereby providing moisture. The evaporation is carried out, and the temperature inside the extrusion cylinder 121 is heated to a predetermined melting temperature.

In addition, the melt heater 123 heats and removes the solidified molten resin after the system 100 is shut down.

The conveying screw 125 is accommodated along the longitudinal direction in the extrusion cylinder 121, and rotates in one direction by the driving of the screw drive unit 127, the waste synthetic resin introduced into the extrusion cylinder 121 extrusion cylinder 121 Extruded to the outlet 121b region of the).

Here, the screw drive unit 127 is a configuration for rotating the rotary shaft of the transfer screw 125, the structure of directly connecting the rotary shaft of the transfer screw 125 or the rotational force of the motor using a belt pulley or a chain sprocket, etc. It may be provided in various configurations and structures, such as a structure for transmitting to the rotating shaft of (125).

On the other hand, the debris removal device 130 is included in the melted resin from the extrusion cylinder 121 is coupled to the head 131 and the head 131 to be opened and closed to the outlet 121b region of the extrusion cylinder 121. It has a filter network (138) for filtering the foreign matter.

The head 131 is formed with an extrusion hole 133 corresponding to the outlet 121b of the extrusion cylinder 121, and in this extrusion hole 133, a porous extrusion part having a hole 135a formed on a plate surface ( 135).

In addition, at one side circumferential region of the porous extrusion unit 135 facing the extrusion cylinder 121 outlet 121b, a filtering network coupling unit 137 to which the filtering network 138 is detachably coupled is formed.

In addition, the filter net 138 has a size smaller than that of the diameter of the pores 135a of the porous extrusion unit 135, and the size of the mesh 138a is detachably coupled to the filter net coupling unit 137 of the head 131. It is.

Here, the filter net 138 may be used to replace the filter net 138 having a suitable size of the net wood 138a according to the type of waste synthetic resin.

By such a configuration, the conventional waste synthetic resin recycling system 100 is a waste synthetic resin supplied into the extrusion cylinder 121 through the material input unit 110 by the rotation of the transfer screw 125 and the heating of the molten heater 123. While being melted in the extrusion cylinder 121, it is extruded and transferred to the foreign matter removing apparatus 130 side.

And, as shown in Figure 2, the molten resin extruded and transported to the foreign matter removing device 130, after the foreign matter is removed while passing through the filter network 138, while passing through the pores (135a) of the porous extrusion unit 135 It is formed of a wire-shaped recycled resin 140 is discharged to the outside through the extrusion hole 133 of the head 131 of the head 131.

The recycled resin 140 discharged in the form of a wire is manufactured into a plurality of granules having a predetermined size through a cutting process, which is a post-work.

However, in the conventional waste synthetic resin recycling system, when foreign matter is caught in the filter net of the debris removal device and the net is blocked over the entire area of the filter net, the operator has to open the head separately from the outlet area of the extrusion cylinder to replace the filter net. there was.

In particular, since the time for blocking the mesh of the filter network is relatively short, the operation of the recycled resin recycling system is frequently stopped and the filter network is frequently replaced, resulting in a very inconvenient production of recycled resin and a significant drop in productivity.

In addition, since the melt remaining in the porous extruder is cured when the filter sheet is replaced, the process of removing the residual melt in the porous extruder is required to restart the waste synthetic resin recycling system. Thereby, there existed a problem that productivity fell further.

In order to solve this problem, a device as illustrated in FIGS. 3 and 4 has been developed in the related art, and its specific configuration and operation are as follows.

First, referring to the configuration, the supply unit 210 for collecting and melting and supplying the waste synthetic resin and the molten waste synthetic resin (hereinafter, referred to as "melt") introduced from the supply unit 210 are elongated in the shape of noodles. It is composed of a molding unit 220.

When the filter 239 provided on one side of the die 230 is blocked by foreign matter, the waste synthetic resin recycling apparatus is stopped, and then the die 230 is rotated so that the inlet 235 of the supply pipe 221 is rotated. Communicate with the outlet 225.

Then restart the waste plastics recycling unit.

However, according to the prior art, since the melted synthetic resin is extruded, a filter for removing the foreign matter is passed through, so that there is a limitation in removing the foreign matter as well as the work delay caused by the foreign matter.

In addition, since the filter 239 for removing various foreign matters contained in the molten synthetic resin is installed at the end of the expansion hole 237, the filter is limited in size and should be manufactured in a shape corresponding to the end of the expansion hole 237. Therefore, unnecessary waste is generated.

Due to the size of the filter 239, the waste synthetic resin is replaced about 50 times when working about 4 to 5 tons, and in order to replace the filter 239, it is necessary to rotate hundreds of kg of heavy materials. It takes a long time, safety accidents such as injuries to workers occur frequently, as well as the equipment must be built frequently, there was a problem that the productivity is lowered.
