Description

Extruder of waste synthetic resin recycling apparatus {Regenerative Compression apparatus of waste plastics}

The present invention relates to an extruder of a waste synthetic resin recycling apparatus, and more particularly, extrusion of a recycling apparatus for processing waste synthetic resins such as waste water containers or agricultural waste vinyl, polyolefins used for various packaging materials, and processing them into raw materials that can be recycled. As the filter is driven in the form of a drum in the gas phase and driven by a worm gear type, impurities such as stones, soil, and paper contained in the waste synthetic resin are continuously removed and discharged, and the melt flows through the filter smoothly. The present invention relates to an extruder of a waste synthetic resin recycling apparatus having improved extrusion performance.

In general, synthetic resins are light weight, inexpensive, and have excellent processability. Therefore, they are applied to various fields for producing beverage containers, various parts, and vinyl. As a result, the demand is soaring, about 14.2 million tons are produced annually, and about 8,880,000 tons are discharged as waste, and some of the waste is recycled through a recycling process.

The recycling process of waste is divided into simple regeneration and complex regeneration according to the impurity levels in the waste synthetic resin material.The waste is recycled through simple regeneration process such as bari and chips generated during the processing of synthetic resin, Waste vinyl or industrial and household wastes are recycled through a complex regeneration process because a large amount of impurities are contained in the waste.

In this case, in the case of the complex regeneration, impurities contained in the waste are removed in advance through a process such as sorting, drying, crushing, and washing, and then introduced into a regeneration apparatus, and processed into a raw material that can be recycled through a melt process. However, impurities such as stones, soil, paper, and metal pieces of fine size cannot be completely removed by the above process, and thus foreign matters are caught in the regeneration device and the extruder, preventing the smooth operation. In addition to the loss of additional working time and costs, even if processed into a recyclable raw material has a disadvantage that has a detrimental effect on the quality and utilization value of the raw material due to the inclusion of impurities.

On the other hand, in order to solve the above-mentioned disadvantages, the transport and recovery is installed in a tape method in a state in which the catching network is in close contact with the outer periphery of the head of the extruder, and a cylinder and a reverse rotation prevention clutch are mounted on the top of the gear The train works in conjunction with the head to filter out impurities contained in the melt. However, as the head portion is divided and rotated at a constant angle by the cylinder and the anti-rotation clutch, the progress of the melt discharged through the head portion is not smoothly performed continuously.

In addition, the catching net which is in close contact with the outer circumferential surface of the head part and is supplied and recovered by tape method is periodically removed and reinstalled after removing impurities. At this time, the filtered impurities are removed by the method of burning by applying high heat to the catching net. It melts or deforms by this high temperature too many times. As a result, the replacement cost of consumable parts is not only incurred due to the inability to use the hook network repeatedly, but the work space for replacing consumables periodically leads to a fatal decrease in productivity in industrial machines using heaters.

Accordingly, the present invention is to solve the above-mentioned disadvantages, the filter on the extruder of the regeneration apparatus to melt the waste synthetic resin, such as beverage containers or agricultural waste vinyl, polyolefin used as various packaging materials and to process the raw material to be recycled. Is driven by the worm gear type through the drum shape, and it continuously removes and discharges impurities such as stones, soil, and paper contained in the waste synthetic resin, and smoothly flows the melt through the filter. It is an object of the present invention to provide an extruder of an improved waste synthetic resin recycling apparatus.

The discharge hole 14 has the same upper and lower widths as the first inlet 12 and is provided with a trapping plate 60 to be described later.

In addition, the drum 20 of the present invention is inserted into the outer housing 10 through the upper gear 22 on the upper end, a plurality of through holes (20a) is formed on the outer peripheral surface. The drum 20 has a cylindrical shape through which a plurality of through holes 20a are formed on the outer circumferential surface thereof and are continuously rotated by the operation of the worm gear 22 installed at the upper end thereof. The outer diameter of the drum 20 is processed to the inner diameter and precision tolerances of the outer housing 10 to prevent play during rotation of the drum 20 inserted in the outer housing 10 as well as the drum 20 and the outer housing. Penetration of the melt is prevented between the interfaces at which (10) is in close contact. At this time, the through hole 20a provided on the outer circumferential surface of the drum 20 is a hole through which the melt flowed in through the first inlet 12 of the outer housing 10 passes, and is compact so as not to interfere with the removal of impurities and circulation of the melt. Formed at intervals.

In this case, the drum 20 has a cylindrical filter 50 interposed in the section in which the through hole 20a is formed, and the filter plate on the discharge hole 14 of the outer housing 10 to be in close contact with the filter 50. 60) is installed.

Rotate 40. As shown in FIG. 2, the conveying screw 40 has a relatively narrow protrusion width of the screw plate 40c on the rotation shaft 40b, which flows in through the second inlet 32 of the inner housing 30. It is possible to prevent the molten liquid from flowing back during transport in the downward direction.

1 to 4 describe the operating state of the extruder according to the present invention.

First, waste synthetic resins such as polyvinyl chloride, polystyrene, polyethylene, etc., which are used as beverage containers or various packaging materials, are removed in advance by processes such as sorting, drying, crushing, and washing, and then transported through a hopper. Supplied as 1). Subsequently, the waste synthetic resin is melted in a liquid state by a banding heater (not shown) of the feeder 1 and flows into the extruder. At this time, the molten liquid introduced through the first inlet 12 of the extruder is placed on the drum 20. After the impurities are filtered by the interposed filter 50 and the through hole 20a, the impurities are filtered through the second inlet 32 of the inner casing 30 and then transferred to the lower portion and discharged to the extrusion die D. do. In this case, as the drum 20 interposed between the filters 50 is continuously rotated by the worm gear 22, the flow of the melt is always constant.

In addition, impurities such as stones, soil, paper, and metal pieces of fine size filtered by the filter 50 are removed by scraping by a trapping plate 60 installed on the discharge hole 14 of the outer casing 10. Then, it is collected to the outside through the discharge hole 14.

As such, as the drum 20 and the filter 50 are continuously rotated by the operation of the worm gear 22, the impurities are removed and collected on the filter 50 by the filter plate 60 as well as the impurities. As the process is performed continuously, there is an advantage that the maintenance of the regeneration apparatus is easy and the extrusion performance is improved.

According to the constitution and function of the present invention, the filter is drum-shaped on an extruder of a regeneration apparatus that melts waste synthetic resins such as beverage containers or agricultural waste vinyl and polyolefins used for various packaging materials and processes them into recyclable raw materials. As the worm gear is driven, the removal and discharge of impurities such as stones, soil, and paper contained in the waste synthetic resin are continuously performed, and the melt flows through the filter to facilitate the extrusion performance.
