Description

Large melter of waste resin {.}

The present invention is to enable the recycling of the plastic waste and various resins generated in everyday life used when growing greenhouses or crops in rural areas

The present invention relates to a large melt apparatus for waste resin that enables the melt supply of various waste resins using a single screw and to remove foreign substances in the melting process.

Waste plastics generated during the cultivation process of vinyl houses or crops, which are formed for the purpose of producing various vegetables and fruits in rural areas, are collected and incinerated or left in one place, causing environmental pollution.

In addition, packaging vinyl and thermoplastic resins generated in daily life are collected with general garbage and simply incinerated or landfilled, and thus cannot be recycled.

The waste vinyl and resins are recycled using a pair of screws, and a ferrite method is pulverized and dried to melt the resin.

However, in the melting method using a screw, the collected waste vinyl or resin is supplied and melted while applying heat to be applied to the recycled product.However, it is difficult to form the recycled product by the foreign matter included in the melting, and it is a large-capacity product such as a septic tank. In order to mold the melter that can melt a large capacity should be proposed even if the situation is not.

In addition, the collected waste vinyl has a very long length or is agglomerated into agglomerates. Therefore, it is slow to be formed because it is cut into a sickle by manual labor before entering into the inlet. In addition, since a large amount of foreign matter is not removed from the molten resin that is difficult, it is recycled as a low grade raw material.

In addition, the ferrite method causes secondary water pollution due to wastewater generated during washing along with the drawback that the material cost of the raw material is reduced when recycling the waste vinyl, but the recycling cost is expensive.

The waste resin melting apparatus of Korean Patent Application Laid-Open Publication No. 98-15477 (published May 25, 1999) has a molten bath installed horizontally, and is disposed inside the molten bath and rotated at an inner center of the molten bath by a driving member to remove waste vinyl. Melting, rotating drum having a screw and a backscrew on the outer periphery; It is configured to rotate with a pair of drive members on both sides of the rotating drum

Rotating drum is supported on both sides, and supplying waste vinyl by twin screw method was to cut to a certain size by screw, to volatilize air layer and water contained in waste vinyl, and to easily cut waste resin.

However, the use of a pair of screws requires a large area, and because the internal temperature is lowered due to the moisture generated inside, the melt rate decreases, which lowers the production capacity. It was very difficult to remove the debris.

In addition, the bearings are easily damaged due to the heat generated from the nozzles, which causes frequent repairs, and the waste vinyl supplied from the staying space is only idling and cannot be drawn in. There is a risk of fire because the flames generated inside flow back into the hopper. .

The present invention is to provide a large-capacity melting apparatus with a daily processing capacity of 10 tons or more.

The present invention is to use a single screw and to melt and supply the waste vinyl or resin supplied by varying the interval of the screw.

The present invention is to allow the smoke of the heat source to be supplied is discharged from the outside, so that the heat source is not transmitted to the bearing and to remove the foreign matter contained in the melting process.

The present invention is to provide a high-quality raw material while removing the foreign matter in the resin supply apparatus once again the molten resin.

The present invention is divided into two upper and lower bodies and is installed on the outside of the rotary tube and one screw is narrowed toward the inside, the preheating and compressing portion, the foreign matter removing portion and the molten resin passed through the molten portion is supplied in the resin discharge device It is characterized by consisting of a resin supply device for removing the foreign matter and supply the molten resin.

In the present invention, the rotary tube 11 is horizontally installed, and the shafts 19 and 19 'protrude from both sides, and are supported by the bearings 20 and 20' so that the motors 23 to the gears 22 and 22 'are supported. A screw rotator 6 or 6 'is installed to be connected to 23' and rotated.

The rotary tube 11 is a hollow state and the nozzle 15 is inserted so that high heat is supplied from the outside so that the supplied vinyl or waste resin is attached to the screw 12 without being stuck or slipped.

Screw 12 is installed to the outside of the rotary tube 11 has a larger diameter on the side with the hopper 25 and the gap is narrowed toward the inside so that the melt supply of the resin using a single screw 12 Is to make this possible.

On the right side of the rotary tube 11, the smoke discharge port 16 is formed to discharge the smoke generated by the heat source supplied from the nozzle 15, and the blocking plate 17 is installed on both sides of the heat insulating material 18 to the outside to rotate. The heat source of the pipe 11 is prevented from being supplied to the shaft 19 so as not to affect the bearing 20, and at the same time, the water cooling pipe 21 is installed outside the bearing 20 to be transmitted to the bearing 20. Lowering the temperature minimizes the effect.

The upper body 9 and the lower body 10 are bisected and heat medium supply pipes 9a and 10a are formed therein, respectively, and a heat source is supplied from the outside, and the upper connector 9 'and the lower connector 10' are provided at both sides. Is formed and is normally fixed to the high information bolt 44.

The resin melting apparatus 1 composed of the upper body 9 and the lower body 10 is preheated and compressed in the inside of the hopper 25 and the compression unit 2,

And the foreign matter removal unit (3) to reduce the internal space along the inclined surface (1 ') to one side of the preheating and compression unit 2 and to remove the pre-melting and foreign matter,

It is made of a melting portion 4 that is discharged by melting to one side of the foreign matter removing unit (3).

In the case of the waste vinyl collected through the hopper 25, the preheating and the compressing unit 2 is supplied using hydraulic crane without any separate work.

The supplied waste vinyl is compressed while being preheated through a screw 12 heated by a heat source supplied to the nozzle 15, and is gradually delivered and moved inward.

At this time, a part of the air layer and water contained in the waste vinyl is volatilized through the hopper 25 as a heat source, and when a large amount of water is contained, it is discharged and treated through the water outlet 29 from the lower side.

The preheating and compressing unit 2 is a place where the injected waste vinyl stays and is uniformly compressed by the rotation of the screw 12 and is gradually transferred to the foreign matter removing unit 3.

In the foreign matter removal unit 3, the melting is gradually performed, and the reverse screw 13 is installed outside the rotary tube 11 so that only the melt passes through, and foreign substances such as stones, which are relatively heavy, are caught in the reverse screw 13. It does not enter and is moved downward by the specific gravity to remove foreign matter primarily through the foreign matter discharge port 30.

In addition, a gas discharge port 32 is formed on the upper side to discharge various gases generated while melting.

After passing through the foreign matter removing unit 3, the molten unit 4 is almost melted and discharged from the tip to the lower resin supply device 5 through the outlet 31.

At this time, the reverse screw 14 in the opposite direction to the screw 12 is installed at the front end of the rotary tube 11 so that the supplied melt can no longer be transported and is discharged to the lower outlet 31.

Therefore, in the present invention, the gap of the screw 12 is narrowed toward the inside, and is formed along the shape of the inside to enable transport by melting the waste vinyl with one screw 12, and idling in the preheating and compression unit 2. It is to be supplied without being made.

The resin discharge device 8 has discharge plates 41 and 41 'having discharge holes 42 formed at both sides thereof, and guide plates 43 formed at right angles, and gears 36 having larger diameters at one side thereof. Coupled to 37 is a cylinder shaft 39 at a portion of the gear 37 connected to the hydraulic cylinder 38 and at the same time through a hinge point 40.

Then, the hydraulic cylinder 38 is to reciprocate the cylinder shaft 39 to a predetermined stroke distance, so the gear 37 is repeated to rotate left and right.

When the gear 37 rotates left and right, the small gear 36 rotates left and right while rotating the discharge plates 41 and 41 'to the left and right.

When the discharge plate 41 and 41 'are rotated left and right on both sides, the molten resin supplied therein is discharged through the discharge hole 42 of the discharge plate 41' coming in, and the discharge plate 41 'is outside. Rotated in and the discharge plate 41 is introduced into it to discharge the molten resin supplied therein through the discharge hole (42).

Accordingly, when the discharge plates 41 and 41 'are rotated left and right by the hydraulic cylinder 38, the molten resin is discharged through the discharge hole 42, and the guide plate 43 is appropriately melted. Stirring acts, and foreign matters or resins that cannot be melted that do not pass through the discharge hole 42 are stuck to the discharge plates 41 and 41 'inside, so that the discharge plate is not supplied properly. The inside of the 41 is scraped off with a flat plate to remove foreign matters, so that a high quality molten resin can be always provided.

Since the above-mentioned resin melting apparatus 1 was able to process about 15 tons of waste vinyl per day, it was possible to mold large resin products such as telecommunications manholes or integrated septic tanks.

The present invention is to provide a large capacity melter with a daily processing capacity of more than 10 tons to recycle a lot of waste vinyl.

The present invention is to use a single screw and to form a narrower gap between the screws to melt the supplied vinyl or resin supplied using only one screw.

The present invention is to allow the smoke of the heat source to be supplied is discharged from the outside, so that the heat source is not transmitted to the bearing and to remove the foreign matter contained in the melting process.
