Description

Technical Field

[0001] This invention relates to the field of artificial turf recycling technology, and in particular to a device for recycling and reproducing yarn from waste artificial turf. Background Technology

[0002] With the widespread use of artificial turf in sports stadiums, parks, and courtyard decorations, the amount of waste artificial turf generated after its lifespan has increased dramatically year by year, becoming a type of solid waste that is difficult to degrade naturally. Waste artificial turf is mainly composed of PE / PP grass fibers, styrene-butadiene rubber / PU backing, and fillers such as quartz sand and rubber granules. If traditional treatment methods such as landfill and incineration are used, it will cause serious environmental pollution. At present, the technology of recycling waste artificial turf to produce yarn is gradually being promoted. Its core process usually includes crushing, conveying, melting, impurity removal, and drawing. Among them, the crushing process is the first step in recycling and directly affects the processing efficiency of subsequent processes and the quality of the finished yarn. Most existing waste artificial turf shredding equipment uses a single shredding roller for shearing and shredding. To improve the shredding effect, some equipment adds a pressure structure to assist in pressing the material. The pressure plates of the existing pressure mechanisms are mostly smooth, which can easily cause the material to slip and deviate when in contact with waste artificial turf. In particular, when the waste turf fibers are tangled and the adhesive is aged and stuck together, the smooth pressure plate cannot effectively hold the material, causing the material to overflow to both sides after being pressed, and failing to make full contact with the shredding roller. This not only reduces the shredding efficiency, but also causes uneven particle size. Subsequent melting and fiber drawing processes are prone to problems such as excessive impurities and fiber breakage. Summary of the Invention

[0003] The purpose of this invention is to provide a waste artificial turf recycling and yarn production processing equipment to solve the problems mentioned in the background art, such as the entanglement of waste turf fibers, the aging and adhesion of the backing adhesive, and the inability of the smooth pressure plate to effectively grip the material, causing the material to overflow to both sides after being pressed and unable to fully contact the crushing roller.

A second motor is fixedly installed on the outer surface of the conveying pipe, and an auger is rotatably installed inside the conveying pipe. The output shaft of the second motor is fixedly connected to the auger.

[0009] As a preferred embodiment of the present invention, a filter assembly is provided on the conveying pipe. The filter assembly includes a filter box that is connected to and installed on the outer surface of the conveying pipe. A filter screen for filtering plastic debris and impurities after crushing is provided on the surface of the filter box near the conveying pipe.

[0010] As a preferred embodiment of the present invention, the conveying pipe is provided with a heating component for melting and heating the plastic, and the free end of the conveying pipe is provided with a cleaning mechanism. The cleaning mechanism includes a processing box disposed at the free end of the conveying pipe. The surface of the processing box near the conveying pipe has a wire outlet hole. An annular cavity is fixedly installed on the surface of the processing box near the conveying pipe.

[0012] As a preferred embodiment of the present invention, a connecting pipe is installed between the output end of the air pump and the internal space of the auger, and a rotating disk is provided between the connecting pipe and the auger.

[0013] As a preferred embodiment of the present invention, the connecting tube is provided with an adsorption assembly, the adsorption assembly includes an annular tube connected to and installed on the connecting tube, a pull rope is slidably installed inside the annular tube, and pistons are provided at both ends of the pull rope inside the annular tube, the annular tube is filled with activated carbon fragments between the two pistons.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides multiple conical spikes on the surface of the pressure plate body near the crushing roller. Combined with the pressure of the telescopic component, these spikes effectively bite and pierce waste artificial turf, preventing material slippage and deviation, and ensuring full contact between the material and the crushing roller. Simultaneously, the moving plate, spring, and protrusions inside the pressure plate body work together to automatically remove impurities clogging between the spikes, preventing spike failure. Combined with the guiding effect of the arc-shaped baffle on the crushed fragments, the crushed material has a uniform particle size, reducing clogging and jamming.

[0015] 2. This invention uses a device that sequentially sets up a filtration component, a cleanup mechanism, and an adsorption component to form a multi-stage cleanup system. The filtration component filters out large particulate impurities from the crushed material through a filter screen. The cleanup mechanism uses a scraper to remove solid impurities from the molten plastic liquid and collects them in a collection box. The adsorption component uses activated carbon to adsorb harmful impurities and odors from the gas, effectively removing various impurities such as sand, rubber scraps, and metal scraps from waste turf, avoiding impurities from affecting the melting uniformity and spinning effect, and significantly improving the mechanical properties and appearance quality of the recycled yarn.

[0016] 3. This invention collects the waste heat generated during the operation of the conveying pipe and heating components through the exhaust pipe. After being transported to the heat storage box by the air pump, the waste turf in the crushing box is preheated through the heat spray pipe, which reduces the crushing difficulty and energy consumption during the crushing process. At the same time, the air pump transports the preheated gas to the inside of the auger through the connecting pipe and sprays it out through the air hole. This can not only assist in the conveying of materials and prevent materials from sticking, but also make full use of waste heat, realize energy recycling, and reduce the overall energy consumption of the equipment.

[0017] 4. In this invention, after the material is melted and conveyed by the auger, it is discharged through the yarn outlet and then processed into yarn through the processing box. At this time, the auger rotation, in conjunction with the scraper, can filter the molten plastic liquid, thereby reducing impurities and sand in the liquid, improving the integrity of the subsequent yarn forming process, and ensuring the quality of the yarn.

[0018] 5. This invention can perform complete crushing, conveying, melting, impurity removal, and fiber drawing of waste artificial turf, transforming the difficult-to-degrade waste turf into reusable yarn raw materials, effectively reducing environmental pollution caused by landfilling and incineration of waste turf, and improving the recycling rate of plastic resources; at the same time, through multi-stage physical impurity removal and residual heat temperature control anti-sticking design, it effectively prevents the formation of stress concentration points or bubble breakage points in the plastic liquid during subsequent extrusion and fiber drawing process, which is expected to significantly reduce the continuous stretching breakage rate of recycled yarn and greatly improve the mechanical strength and stretching yield of finished grass fibers.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-10This invention provides a waste artificial turf recycling and yarn production processing device, including a crushing box 23, a feed pipe 1 connected to the top of the crushing box 23, a crushing mechanism 2 inside the crushing box 23, the crushing mechanism 2 including multiple crushing rollers 25 rotatably installed inside the crushing box 23, a drive mechanism 21 fixedly installed on the outer surface of the crushing box 23, the output shaft of the drive mechanism 21 driving the multiple crushing rollers 25 to rotate through a gear set 22, a pressurizing component 26 inside the crushing box 23, the pressurizing component 26 including a support rod 263 slidably installed on the top of the crushing box 23, a telescopic member 262 fixedly installed at the bottom end of the support rod 263, a pressure plate component 261 fixedly installed at the end of the telescopic member 262 near the crushing rollers 25, the pressure plate component 261 including a pressure plate body 2611 fixedly installed at the free end of the telescopic member 262, and multiple conical spikes 2616 provided on the surface of the pressure plate body 2611 near the crushing rollers 25.

[0023] When the drive mechanism 21 is powered on, the rotation of its output shaft, through the meshing transmission of the gear set 22, can drive the multiple crushing rollers 25 installed inside the crushing box 23 to rotate synchronously in the same direction or in opposite directions, entering the crushing preparation state. At the same time, the pressurizing component 26 is activated. The telescopic component 262 in the pressurizing component 26 begins to extend after being powered on or vented, pushing the pressure plate component 261, whose free end is fixed, to move downward toward the crushing roller 25 until the multiple conical spikes 2616 on the surface of the pressure plate body 2611 contact the waste artificial turf on the surface of the crushing roller 25. As the telescopic component 262 continues to apply pressure, the conical spikes 2616 penetrate into the waste artificial turf. The cone 2616 firmly fixes the turf to the surface of the crushing roller 25, preventing the material from sliding or deviating during the crushing process. While the cone 2616 continuously applies pressure to fix the turf, the rotating crushing roller 25 uses its surface teeth to shear and squeeze the fixed waste artificial turf, thus crushing the turf. During this process, since the support rod 263 is slidably installed on the top of the crushing box 23, it can flexibly adjust its position as the pressure plate component 261 moves, ensuring that the pressure plate component 261 applies pressure to the material accurately and always corresponds to the working area of ​​the crushing roller 25, until a single crushing action is completed, and the crushed material falls into the bottom of the crushing box 23.

[0024] In some embodiments, a slide plate 264 is fixedly installed on the top of the support rod 263, a first motor 266 is fixedly installed on the outer surface of the crushing box 23, a circular plate 267 is fixedly installed on the output shaft of the first motor 266, a circular rod 265 is fixedly installed on the outer surface of the circular plate 267, and the circular rod 265 is slidably installed inside the slide plate 264.

[0025] The process involves starting the first motor 266, whose output shaft drives the circular plate 267 fixed at the end to rotate synchronously. The circular plate 267 drives the circular rod 265 to perform circular motion together. When the circular rod 265 performs circular motion, it is limited by the sliding groove of the sliding plate 264, and the circular motion is converted into the reciprocating linear motion of the sliding plate 264 in the horizontal direction. The reciprocating linear motion of the sliding plate 264 drives the support rod 263 at the bottom to move back and forth synchronously, which in turn drives the telescopic component 262 and the pressure plate component 261 to perform reciprocating linear motion together. During this process, the telescopic component 262 always maintains a pressurized state on the pressure plate component 261, so that while the pressure plate component 261 is moving back and forth, it continuously and evenly presses the waste artificial turf on the surface of the crushing roller 25. With the continuous rotation of the crushing roller 25, the material is continuously and comprehensively crushed, avoiding insufficient crushing due to local material not being compacted.

[0026] In some embodiments, two baffles 24 for guiding the fragments crushed by the crushing roller 25 are fixedly installed on the inner wall of the crushing box 23 near the crushing roller 25, and the crushing roller 25 is located between the two baffles 24, which are arc-shaped.

[0027] When the crushing roller 25 crushes the waste lawn, the resulting fragments will scatter in all directions under its own weight and the rotational force of the crushing roller 25. The arc-shaped baffle 24 can block and guide the scattered fragments, directing them to the working area of ​​the crushing roller 25 or the discharge port at the bottom of the crushing box 23, preventing the fragments from adhering to the inner wall of the crushing box 23 or accumulating on both sides of the crushing roller 25, and accelerating the discharge speed of the fragments.

[0028] In some embodiments, a movable plate 2614 is slidably installed inside the pressure plate body 2611, a spring 2613 is fixedly installed between the movable plate 2614 and the inner wall of the pressure plate body 2611, a plurality of protrusions 2615 for clearing impurities blocking the conical spikes 2616 are slidably passed through the movable plate 2614 at the position between the two conical spikes 2616, and a buffer pad 2612 is fixedly installed on the back of the pressure plate body 2611.

[0029] When the pressure plate component 261 applies pressure, the spikes 2616 pierce into the waste turf, and some impurities get stuck between the two spikes 2616, causing a decrease in the biting ability of the spikes 2616. When the telescopic component 262 extends, the telescopic end at the front end of the telescopic component 262 pushes the spring 2613 to compress downward. At this time, the spring 2613 drives the moving plate 2614 to slide up and down, and the protrusions 2615 on the moving plate 2614 slide synchronously and insert between the two spikes 2616 to push out the blocked impurities, prevent the spikes 2616 from failing, and ensure the long-term stability of the pressure and biting effect of the pressure plate component 261. The buffer pad 2612 on the back of the pressure plate body 2611 can buffer the impact force when the telescopic component 262 applies pressure and avoid rigid collision.

[0030] In some embodiments, a conveying mechanism 3 is provided at the bottom end of the crushing box 23. The conveying mechanism 3 includes a conveying pipe 34 connected to the bottom end of the crushing box 23. A second motor 31 is fixedly installed on the outer surface of the conveying pipe 34. An auger 32 is rotatably installed inside the conveying pipe 34. The output shaft of the second motor 31 is fixedly connected to the auger 32.

[0031] When the second motor 31 starts, its output shaft drives the auger 32 to rotate inside the conveying pipe 34. The spiral blades of the auger 32 push the fragments along the length of the conveying pipe 34 to realize the continuous conveying of the crushed material and transport the material to the subsequent melting and impurity removal processes.

[0032] In some embodiments, a filter assembly 33 is provided on the conveying pipe 34. The filter assembly 33 includes a filter box 331 connected to the outer surface of the conveying pipe 34. A filter screen 332 for filtering crushed plastic fragments and impurities is provided on the surface of the filter box 331 near the conveying pipe 34.

[0033] Among them, the filter screen 332 on the side of the filter box 331 near the conveying pipe 34 can block large particles of impurities in the crushed material, allowing only plastic fragments that meet the particle size requirements to pass through the filter screen 332 into the subsequent section of the conveying pipe 34. Large particles of impurities are intercepted inside the filter box 331, reducing the wear of impurities on the heating component 4, auger 32 and spinneret orifice, reducing the probability of equipment failure, and improving the purity of the conveyed material, ensuring uniform melting of plastic in the subsequent melting process, and guaranteeing the quality of recycled yarn.

[0034] In some embodiments, a heating element 4 for melting and heating plastic is provided on the conveying pipe 34, and a cleaning mechanism 5 is provided at the free end of the conveying pipe 34. The cleaning mechanism 5 includes a processing box 53 provided at the free end of the conveying pipe 34. The processing box 53 has a wire outlet hole on its surface near the conveying pipe 34. An annular cavity 52 is fixedly installed on the surface of the processing box 53 near the conveying pipe 34. A plurality of scraper screens 51 for scraping solid impurities in the molten plastic liquid are fixedly installed at one end of the auger 32 located inside the annular cavity 52. ​​A receiving box 54 for collecting solid impurities is provided on the outer surface of the annular cavity 52.

[0035] When the heating component 4 on the conveying pipe 34 is working, it heats the plastic debris inside the conveying pipe 34, causing the plastic debris to melt and form molten plastic. The molten plastic is then conveyed by the auger 32 to the free end of the conveying pipe 34 and enters the annular cavity 52. ​​The scraper (51) rotates synchronously and intercepts solid impurities in the molten plastic. The bottom of the annular cavity (52) is connected to a slag discharge channel. A variable pitch slag discharge screw is installed coaxially inside the slag discharge channel. The scraped impurities are continuously squeezed outward by the slag discharge screw to dehydrate and form a dense solid impurity plug. Finally, the plug breaks through the outlet resistance and falls into the receiving box (54) for collection. The dense impurity plug forms a dynamic flow-blocking seal in the slag discharge channel, thereby maintaining the high working pressure required for filament drawing inside the annular cavity (52) while discharging solid impurities. Furthermore, the purified molten plastic is extruded through the filament outlet hole on the surface of the processing box 53 to form nascent filaments.

[0036] In some embodiments, a preheating assembly 37 is provided on the outer surface of the crushing chamber 23. The preheating assembly 37 includes an air pump 373 fixedly installed on the outer surface of the crushing chamber 23. A heat outlet pipe 375 is connected to the output end of the air pump 373, and a heat storage box 374 is provided on the heat outlet pipe 375. A heat spray pipe 376 for preheating plastic is fixedly installed on the inner wall of the crushing chamber 23. An exhaust pipe 372 is connected between the input end of the air pump 373 and the delivery pipe 34. A vent plate 371 for heat dissipation is provided on the exhaust pipe 372.

[0037] The air pump 373 extracts the waste heat gas generated by the heating component 4 in the conveying pipe 34 through the exhaust pipe 372. The vent plate 371 on the exhaust pipe 372 can filter out small impurities in the gas to prevent them from entering the air pump 373. The waste heat gas is then transported by the air pump 373 to the heat storage box 374 for storage, and then transported through the heat outlet pipe 375 to the heat spray pipe 376 on the inner wall of the crushing box 23. The heat spray pipe 376 sprays the waste heat gas into the crushing box 23 to preheat the waste artificial turf entering through the feed pipe 1, reducing the hardness and toughness of the turf and facilitating subsequent crushing.

[0038] In some embodiments, a connecting pipe 35 is installed between the output end of the air pump 373 and the internal space of the auger 32, and a rotating disk is provided between the connecting pipe 35 and the auger 32. The surface of the auger 32 is provided with a plurality of air holes for spraying plastic.

[0039] Among them, the air pump (373) transports the preheated gas through the connecting pipe (35) to the solid conveying area at the front of the auger (32), and sprays it out through the air hole to assist in conveying and prevent sticking; at the same time, an exhaust port is added above the melting and plasticizing area near the end of the heating component (4) of the conveying pipe (34). The exhaust port is connected to a vacuum pump to force the preheated gas, volatile components and moisture generated by the heating of waste grass mixed in in the early stage to be extracted, and a negative pressure exhaust area is established to ensure that the melt entering the wire outlet hole of the processing box (53) is dense and free of bubbles, making full use of residual heat while avoiding the mixing of gas phase and causing wire breakage; on the other hand, it can blow away the fine dust on the surface of plastic scraps, and at the same time prevent plastic scraps from sticking to the surface of the auger 32 and the inner wall of the conveying pipe 34.

[0040] In some embodiments, an adsorption assembly 36 is provided on the connecting tube 35. The adsorption assembly 36 includes an annular tube 363 connected to and installed on the connecting tube 35. A pull rope 361 is slidably installed inside the annular tube 363. Pistons 362 are provided at both ends of the pull rope 361 inside the annular tube 363. Activated crushed carbon 364 is filled between the two pistons 362 in the annular tube 363.

[0041] The waste heat gas delivered by the air pump 373 enters the annular tube 363 through the connecting pipe 35. After passing through the activated carbon fragments 364, harmful impurities and odors are adsorbed, and the purified gas then enters the auger 32. Pulling the pull rope 361 can drive the pistons 362 at both ends to slide inside the annular tube 363, pushing the activated carbon fragments 364 to turn over, preventing the activated carbon fragments 364 from clumping, ensuring the adsorption effect, and facilitating the subsequent replacement of the activated carbon fragments 364.

[0042] Working principle: The drive mechanism 21, through the meshing transmission of the gear set 22, can drive the multiple crushing rollers 25 installed inside the crushing box 23 to rotate synchronously in the same direction or in opposite directions, entering the crushing preparation state; at the same time, the pressurizing component 26 is activated. After the telescopic component 262 in the pressurizing component 26 is powered or vented, it begins to extend, pushing the pressure plate component 261, which is fixed at its free end, to move downward toward the crushing roller 25 until the multiple conical spikes 2616 on the surface of the pressure plate body 2611 contact the waste artificial turf on the surface of the crushing roller 25. As the telescopic component 262 continues to apply pressure, the conical spikes 2616 penetrate. Inside the waste artificial turf, the turf is firmly fixed to the surface of the crushing roller 25 to prevent the material from sliding or deviating during the crushing process. While the cone 2616 continuously applies pressure to fix it, the rotating crushing roller 25 uses the roller teeth on its surface to shear and squeeze the fixed waste artificial turf to achieve the crushing of the turf. At the same time, the support rod 263 works with the first motor 266 to make the pressure plate component 261 reciprocate while continuously and evenly applying pressure to the waste artificial turf on the surface of the crushing roller 25. With the continuous rotation of the crushing roller 25, the material is continuously and comprehensively crushed.
