Description

Technical Field

[0001] The present invention relates to the technical field of plastic waste recycling, and particularly relates to a general plastic compatibilizer waste recycling and treatment device. Background Art

[0002] The main function of a plastic compatibilizer waste recycling and treatment device is to recycle and treat waste materials in the plastic processing process, especially waste materials involving compatibilizers. These waste materials usually consist of plastic raw materials not utilized in the production process, recycled materials, unevenly mixed plastic particles, etc. Plastics such as PE and PP in plastics have a relatively low density, while plastics such as PVC have a relatively high density. The compatibilizer in the plastic can be separated from the plastic through a solvent, and various plastics can be separated by density. The separated plastics and compatibilizers can be separated by different gasification temperatures; the plastic compatibilizer waste recycling and treatment devices in the prior art usually cannot separately recycle various plastics and compatibilizers, and are inconvenient to use. Summary of the Invention

[0003] For the above technical problems, the technical solution adopted by the present invention is: a general plastic compatibilizer waste recycling and treatment device, including a separation mechanism for separating plastic compatibilizers. The separation mechanism includes a separation tank, and a crushing mechanism for crushing plastic waste and a recycling mechanism for recycling plastics and compatibilizers are provided on the separation mechanism; The separation mechanism includes an internally toothed gear rotatably installed on the separation tank. A lower transmission wheel is fixedly installed on the internally toothed gear, and a docking gear is fixedly installed on the lower transmission wheel. An internal gear is rotatably installed on the separation tank, and an externally toothed gear is fixedly installed on the internal gear. The internally toothed gear meshes with the internal gear.

[0004] Further, the separation mechanism further includes an upper discharge slope and a lower discharge slope provided on the separation tank. A solvent for separating compatibilizers is contained in the separation tank. Two upper conveyor wheels and three lower conveyor wheels are rotatably installed in the separation tank. An upper conveyor belt is wound around the upper conveyor wheels, and a number of protrusions are provided on the upper conveyor belt. A lower conveyor belt is wound around the lower conveyor wheels, and a number of push plates are provided on the lower conveyor belt.

[0005] Further, a stirring motor is fixedly installed on the separation tank. Four stirring blades are rotatably installed on the separation tank. The stirring motor drives the four stirring blades to rotate through a transmission belt. A mesh plate is provided in the separation tank, and a number of holes are provided on the mesh plate.

[0006] Further, a motor is fixedly installed on the separation tank. A motor gear is fixedly installed on the motor shaft of the motor. The motor gear meshes with the docking gear. The internally toothed gear drives the upper conveyor wheels and the lower conveyor wheels to rotate through a transmission belt and gear transmission.

[0007] The waste plastics broken by the crushing mechanism enter the solvent in the separation tank, fall onto the lower conveyor belt. The motor drives the motor gear to rotate, driving the docking gear, the lower driving wheel and the inner toothless gear to rotate. The inner toothless gear drives the inner gear and the outer toothless gear to rotate intermittently. The inner toothless gear drives the upper conveyor wheel and the lower conveyor wheel to rotate through the conveyor belt and gear transmission. The plastics are pushed towards the upper discharge slope and the lower discharge slope by the upper conveyor wheel and the lower conveyor wheel. The stirring motor rotates to drive the stirring blades to rotate through the conveyor belt, stirring the solvent to make the solvent mix better with the plastics. Light plastics such as PP and PE float on the upper part together with the compatibilizer, and the heavier PVC sinks to the lower part. The PVC is conveyed to the lower discharge slope through the lower conveyor belt and finally enters the combustion chamber. The PP, PE and compatibilizer are pushed into the upper discharge slope through the upper conveyor belt and finally fall onto the filter plate.

[0008] Further, the crushing mechanism includes a crushing box fixedly installed on the separation tank. A main crushing wheel and a secondary crushing wheel are rotatably installed in the crushing box. A main gear and an upper driving wheel are fixedly installed on the main crushing wheel. A secondary gear is fixedly installed on the secondary crushing wheel. The secondary gear meshes with the main gear. The lower driving wheel drives the upper driving wheel to rotate through the conveyor belt.

[0009] The lower driving wheel drives the upper driving wheel, the main crushing wheel and the main gear to rotate through the conveyor belt. The main gear drives the secondary gear and the secondary crushing wheel to rotate. The waste plastics are put into the crushing box, and the waste plastics are crushed by the main crushing wheel and the secondary crushing wheel.

[0010] Further, the recycling mechanism includes a melting box fixedly installed on the separation tank. A combustion chamber is arranged in the melting box. A filter plate is fixedly installed in the melting box. A plurality of holes are arranged on the filter plate. A collecting hopper is fixedly installed below the filter plate. A discharge pipe is fixedly installed on the collecting hopper. A burner is arranged in the combustion chamber. An exhaust hole is arranged on the melting box.

[0011] Further, a scraping frame is slidably installed in the melting box. The scraping frame is attached to the filter plate. A pulling rod is rotatably installed on the scraping frame. A driving rotating rod is rotatably installed on the pulling rod. A rotating rod gear is fixedly installed on the driving rotating rod. The driving rotating rod is rotatably installed with the separation tank. The rotating rod gear meshes with the outer toothless gear.

[0012] The burner in the combustion chamber ignites the PVC entering the combustion chamber and cooperates with the introduction of other combustion gases to heat and melt the PP, PE and compatibilizer on the filter plate. The melted PP and PE drip into the collecting hopper and finally are discharged from the discharge pipe. The compatibilizer gasifies and is discharged from the exhaust hole. The intermittent rotation of the rotating rod gear and the driving rotating rod drives the pulling rod to rotate, thereby driving the scraping frame to slide intermittently back and forth on the filter plate, pushing the waste materials that cannot be melted into the combustion chamber for combustion.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: (1) The separation mechanism provided by the present invention can separate the compatibilizer and the plastic through the solvent in the separation tank, and at the same time send the plastic with a larger density and the plastic with a smaller density out from different outlets respectively, with good separation effect; (2) The recycling mechanism provided by the present invention can burn the PVC plastic with low recycling value, melt the PE and PP plastics with high recycling value for separate collection, and gasify the compatibilizer with a lower gasification temperature for separate collection, with good collection effect; (3) A plurality of stirring blades for stirring the solvent are arranged in the separation mechanism of the present invention, so that the solvent can fully contact with the plastic, improving the separation effect.

[0031] As Figure 6 , Figure 7As shown, a scraping frame 305 is slidably installed in the melting box 301. The scraping frame 305 is in contact with the filter plate 306.

[0033] The working principle of a waste recycling and treatment device for a general plastic compatibilizer disclosed by the present invention is as follows: The waste plastics crushed by the crushing mechanism enter the solvent in the separation tank 201 and fall onto the lower conveyor belt 214. The motor 204 drives the motor gear 205 to rotate, driving the docking gear 206, the lower driving wheel 207, and the inner toothless gear 208 to rotate.

The stirring motor 216 rotates and drives the stirring blade 217 to rotate through the conveyor belt, stirring the solvent to make the solvent better mix with the plastics. Light plastics such as PP and PE float above together with the compatibilizer, and the heavier PVC sinks below. The PVC is conveyed to the lower discharge slope 203 through the lower conveyor belt 214 and finally enters the combustion chamber 308. The PP, PE, and compatibilizer are pushed to the upper discharge slope 202 through the upper conveyor belt 215 and finally fall onto the filter plate 306. The burner in the combustion chamber 308 ignites the PVC entering the combustion chamber 308 and cooperates with the introduction of other combustion gases to heat and melt the PP, PE, and compatibilizer on the filter plate 306. The melted PP and PE drip into the collection hopper 307 and finally are discharged from the discharge pipe 309. The compatibilizer gasifies and is discharged from the exhaust hole. The rotating rod gear 303 and the driving rotating rod 302 rotate intermittently to drive the pulling rod 304 to rotate, thereby driving the scraping frame 305 to slide intermittently back and forth on the filter plate 306, pushing the waste materials that cannot be melted into the combustion chamber 308 for combustion.
