Description

Technical Field

[0001] The present invention belongs to the technical field of plastic processing, and particularly relates to an environment-friendly production process and equipment for plastic bottle processing. Background Art

[0002] With the continuous growth of the global consumption of plastic bottles, the number of waste plastic bottles generated each year is huge. For example, plastic bottles are widely used for packaging in industries such as beverages and food. The beverage industry alone generates hundreds of millions of waste plastic bottles every year. If these waste plastic bottles are not effectively recycled and processed, they will cause serious pollution to the environment and also a great waste of resources. Therefore, the recycling and reprocessing of plastic bottles have become an important industrial direction, and the demand for environment-friendly production equipment is becoming increasingly urgent.

[0003] In the existing recycling process of plastic bottles, various stains and impurities will be contaminated. The traditional cleaning method usually adopts the way of using cleaning liquid once, resulting in a large amount of water resources being wasted. After cleaning, the cleaning liquid contains impurities such as dirt and grease and is directly discharged without effective recycling and filtration for reuse. This not only causes waste of water resources but also increases the production cost of enterprises;

[0004] Moreover, in the process of crushing and screening plastic bottles, due to the insufficient precision of the equipment, a large number of fragments that do not meet the size requirements often appear. These fragments cannot directly enter the subsequent processing procedures and need to be reprocessed or discarded, resulting in waste of raw materials. Moreover, the traditional equipment does not crush plastic bottles evenly, resulting in some fragments being too large or too small, affecting the quality and efficiency of subsequent processing and indirectly causing waste of resources. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In the above solution, the second motor drives the rotating rod and the dial to rotate. At the same time, the fan-shaped feeding rack rotates driven by the motor. The cooperation of the two can fully stir the materials in the cleaning tank, making the materials fully contact with the cleaning liquid, and improving the cleaning effect.

The filter plate can filter out solid impurities in the cleaning liquid, and the oil absorption plate can adsorb oil stains, realizing the recycling of the cleaning liquid, reducing the consumption of the cleaning liquid and the discharge of waste water.

[0018] 2. In the above solution, the third motor drives the driving gear through the transmission shaft, and then drives the first crusher and the second crusher to mesh and operate, realizing the efficient crushing of the plastic bottle corner waste. The coordinated work of the two crushers can quickly crush the waste into smaller particles, improve the crushing efficiency, and provide a suitable raw material particle size for the subsequent process. The torque limiter is set. When encountering too hard or too large foreign objects, it can automatically limit the torque transmission, avoid damage to the motor and the crusher due to overload, ensure the safe and stable operation of the equipment, reduce equipment failures and maintenance costs, and extend the service life of the equipment.

[0019] 3. In the above solution, the mesh plate in the screening part can screen the crushed materials. The materials that meet the particle size requirements enter the hopper through the feeding pipe and the feeding outlet, while the larger particle materials remain on the mesh plate and continue to be crushed. The shock absorption device effectively absorbs the vibration and impact force generated during the vibration screening process of the screening part, reducing the vibration and noise during the operation of the equipment.

[0037] Embodiment

[0038] Please refer to Figures 1 to 5, the present invention provides a technical solution: an environment-friendly production process and equipment for plastic bottle processing, including a mounting frame 1, a crushing mechanism 2 is disposed through the top of the mounting frame 1, a vibration screening mechanism 3 is disposed at the bottom of the crushing mechanism 2, a feeding hopper 4 is disposed at the left bottom of the vibration screening mechanism 3, a screw conveyor 5 is installed at the bottom of the feeding hopper 4, an ultrasonic cleaning tank 6 is disposed at the bottom of the discharge port of the screw conveyor 5, and a circulating filtration mechanism 7 is disposed inside the ultrasonic cleaning tank 6;

[0039] The circulating filtration mechanism 7 includes a stirring and conveying device 71 and a filter element 72. The stirring and conveying device 71 is arranged at the top inner wall position of the ultrasonic cleaning tank 6, and the filter element 72 is arranged at the bottom inner wall position of the ultrasonic cleaning tank 6. The filter element 72 includes a limit groove 701, a partition plate 707, a solenoid valve 708, a first motor 709, a rotating shaft 719, a worm gear 720, a worm 710, a moving block 711, an L-shaped rod 712, a baffle plate 713, a first pipeline 715, a water storage tank 716, a filter plate 717, an oil absorption plate 718 and a second pipeline 714. A partition plate 707 is fixedly connected to the inner side wall of the ultrasonic cleaning tank 6, and a solenoid valve 708 is installed in the middle of the partition plate 707. A limit groove 701 is opened at the bottom of the inner cavity of the ultrasonic cleaning tank 6, and a first motor 709 is arranged at the bottom of the ultrasonic cleaning tank 6. The output shaft of the first motor 709 penetrates through the bottom of the ultrasonic cleaning tank 6 through a coupling and is rotatably connected to a rotating shaft 719. A worm gear 720 is sleeved on the outer wall of the rotating shaft 719. The worm gear 720 is arranged in the limit groove 701. The inner wall of the limit groove 701 is rotatably connected to a worm 710 through a bearing. The worm gear 720 is meshed with the worm 710. Moving blocks 711 are sleeved on the outer walls on both sides of the worm 710. An L-shaped rod 712 is fixedly arranged at the top of the moving block 711. The outer ends of the two L-shaped rods 712 are fixedly connected to a baffle plate 713. At both ends of the bottom side wall of the ultrasonic cleaning tank 6, a first pipeline 715 and a second pipeline 714 are respectively arranged. A water storage tank 716 is arranged on one side of the bottom of the ultrasonic cleaning tank 6, and the water storage tank 716 is communicated with the ultrasonic cleaning tank 6 through the first pipeline 715. A filter plate 717 is fixedly connected inside the water storage tank 716, and an oil absorption plate 718 is fixedly connected to the inner side wall of the water storage tank 716 below the filter plate 717; The stirring and conveying device 71 includes a second motor 702, a rotating rod 703, a baffle 704, a circular plate 705 and a fan-shaped feeding rack 706. A group of second motors 702 are arranged on the rear side wall of the ultrasonic cleaning tank 6. The output shafts of the two second motors 702 penetrate through the side wall of the ultrasonic cleaning tank 6 and are rotatably connected to a rotating rod 703. A baffle 704 is sleeved on the outer wall of the rotating rod 703. A fan-shaped feeding rack 706 is rotatably connected to one side of the inner cavity of the ultrasonic cleaning tank 6 away from the baffle 704. Circular plates 705 are arranged on both sides of the fan-shaped feeding rack 706; A motor is connected to the input end of the fan-shaped feeding rack 706. The fan-shaped feeding rack 706 is in the shape of an impeller, and through holes are opened on each impeller; An installation hole is opened on one side wall of the baffle plate 713, and internal threads are opened in the installation hole. External threads are opened on one end side wall of the L-shaped rod 712. The L-shaped rod 712 and the baffle plate 713 are connected by threads;

[0040] The second motor 702 in the stirring and conveying device 71 drives the rotating rod 703 and the baffle 704 to rotate. At the same time, the fan-shaped feeding rack 706 also rotates driven by the motor. This rotation enables the plastic bottle fragments to be fully stirred in the cleaning liquid in the ultrasonic cleaning tank 6. During the cleaning process, the filter element 72 is in a standby state. After cleaning for a period of time, the cleaning liquid will contain more impurities and oil stains. At this time, the filter element 72 starts to function. The first motor 709 drives the rotating shaft 719 to rotate. The worm gear 720 on the rotating shaft 719 meshes with the worm 710, driving the worm 710 to rotate. The moving blocks 711 and the L-shaped rods 712 on both sides of the worm 710 move as the worm 710 rotates. Since the L-shaped rod 712 is threadedly connected to the baffle 713, this connection method can precisely control the position of the baffle 713. By controlling the opening and closing of the baffle 713, the discharge of the cleaning liquid is realized. When the cleaning liquid needs to be discharged, the baffle 713 opens, and the cleaning liquid flows into the water storage tank 716 through the first pipeline 715. The cleaning liquid flowing into the water storage tank 716 first passes through the filter plate 717, and the filter plate 717 can filter out the solid impurities in the cleaning liquid. The oil absorption plate 718 located below the filter plate 717 can adsorb the oil stains. The cleaned and oil-removed cleaning liquid can be recycled back to the ultrasonic cleaning tank 6 through the second pipeline 714 to achieve the recycling of the cleaning liquid.

[0041] As Figure 6 shown, the crushing mechanism 2 includes a fixing plate 201, a third motor 202, a transmission shaft 203, a torque limiter 204, a driving gear 205, a driven gear 206, a feeding frame 207, a first crusher 208, a second crusher 209 and a blanking frame 210. The top of the mounting frame 1 is fixedly connected with the fixing plate 201. The inner wall of the fixing plate 201 is penetrated by the feeding frame 207. One side of the fixing plate 201 is connected with the third motor 202 through a mounting seat. The output end of the third motor 202 is connected with the transmission shaft 203. The outer wall of the transmission shaft 203 is sleeved with a torque limiter 204. The top of the transmission shaft 203 is connected with the driving gear 205. A driven gear 206 is arranged on one side of the driving gear 205, and the driving gear 205 is meshed with the driven gear 206. The output ends of the driving gear 205 and the driven gear 206 are connected with the first crusher 208 and the second crusher 209, and both the first crusher 208 and the second crusher 209 are arranged in the feeding frame 207, and the first crusher 208 and the second crusher 209 are meshed with each other. The bottom of the fixing plate 201 is provided with a blanking frame 210, and the blanking frame 210 is communicated with the feeding frame 207;

[0042] It should be noted that after the plastic bottle or its corner waste is fed into the feeding frame 207, the third motor 202 installed on one side of the fixed plate 201 starts to work. At this time, the coordinated cooperation of feeding and motor startup enables the material to be processed in a timely manner, ensuring the continuity of the production process. Driven by the third motor 202, the driving gear 205 and the driven gear 206 are driven, and then the first crusher 208 and the second crusher 209 are driven to mesh and rotate with each other. The design of this double crusher can efficiently crush the plastic bottles entering the feeding frame 207, quickly decompose them into smaller fragments, improve the crushing efficiency, and provide suitable raw materials for subsequent processes such as vibration screening and cleaning. When encountering foreign objects that are too hard or too large during the crushing process, resulting in the torque on the transmission shaft 203 exceeding the set value, the torque limiter 204 will automatically limit the torque transmission, thereby protecting key components such as the third motor 202, the first crusher 208, and the second crusher 209, and avoiding damage due to overload. This greatly extends the service life of the equipment, reduces the maintenance cost and downtime of the equipment.

[0043] As Figure 7 and Figure 8 shown, the vibration screening mechanism 3 includes a screening member 31 and a shock absorption device 32. The screening member 31 is arranged below the blanking frame 210, and the shock absorption device 32 is arranged at the bottom of the screening member 31. The screening member 31 includes a collection frame 301, a mesh plate 302, a blanking pipe 303, and a blanking outlet 304. The inner cavity of the collection frame 301 is fixedly connected with the mesh plate 302. The top end of the left side wall of the mesh plate 302 is provided with a blanking pipe 303. A blanking chamber is formed between the mesh plate 302 and the collection frame 301. A blanking outlet 304 is arranged at the left opening of the collection frame 301. The blanking outlet 304 is arranged above the blanking hopper 4; the shock absorption device 32 includes shock absorbers 306, a mounting plate 307, a base 308, mounting grooves 309, buffer springs 310, and abutting blocks 311. The base 308 is arranged at the bottom of the mounting frame 1. A plurality of mounting grooves 309 are formed in the base 308. Buffer springs 310 are arranged inside the plurality of mounting grooves 309. The top of the buffer spring 310 is connected with an abutting block 311. The top of the abutting block 311 is fixedly connected with a shock absorber 306. The tops of the plurality of shock absorbers 306 are fixedly connected with the bottom of the collection frame 301. An mounting plate 307 is arranged between the base 308 and the collection frame 301. Mounting holes for the shock absorbers 306 to slide are formed on the surface of the mounting plate 307; a vibration motor 305 is arranged at the bottom of the collection frame 301;

[0044] It should be noted that by fixedly connecting the mesh plate 302 in the collection box 301 and utilizing the material discharging chamber formed between the mesh plate 302 and the collection box 301, the screening of the plastic bottle fragments from the crushing mechanism 2 is realized. The vibration generated by the vibration motor 305 enables the plastic bottle fragments to fully jump on the mesh plate 302, increasing the contact opportunity between the fragments and the mesh plate 302, improving the accuracy and efficiency of screening. The fragments meeting the size requirements can pass through the mesh plate 302, enter the material discharging hopper 4 through the material discharging pipe 303 and the material discharging outlet 304, while the fragments not meeting the size requirements remain on the mesh plate 302 and continue to be processed or re-crushed. The combination of the buffer spring 310 and the shock absorber 306 can effectively buffer the vibration of the screening component 31, reduce the impact of the vibration on other components of the equipment, and reduce the noise generated during the operation of the equipment.

[0045] The working principle of the above embodiment is as follows: The plastic bottle corner waste is put into the crushing mechanism 2 from the feeding frame 207. The third motor 202 installed on the fixed plate 201 is started to drive the transmission shaft 203 to rotate. The driving gear 205 on the transmission shaft 203 rotates accordingly, and the driven gear 206 meshing with the driving gear 205 also starts to operate. The output ends of the driving gear 205 and the driven gear 206 are respectively connected to the first crusher 208 and the second crusher 209. The two crushers mesh with each other in the feeding frame 207 to crush the plastic bottle waste. The crushed plastic bottle fragments enter the vibration screening mechanism 3 below through the material discharging frame 210 communicated with the feeding frame 207;

[0046] The fragments fall into the collection box 301 of the vibration screening mechanism 3. The vibration motor 305 at the bottom of the collection box 301 is started, causing the entire collection box 301 and the internal mesh plate 302 to vibrate. Under the action of vibration, the plastic bottle fragments jump on the mesh plate 302. The fragments meeting the size requirements pass through the mesh plate 302 and enter the material discharging chamber formed between the mesh plate 302 and the collection box 301, and then through the material discharging pipe 303 at the top of the left side wall, fall into the material discharging hopper 4 from the material discharging outlet 304 at the left opening of the collection box 301. The fragments not meeting the size requirements are vibrated and moved to the position of the material discharging pipe 303, and an external collection device is used to collect the fragments not meeting the standards. When vibrating, the buffer spring 310 and the shock absorber 306 are used together to absorb the vibration, reduce the impact of the vibration on other components of the equipment, reduce the noise, and ensure the stable operation of the equipment. The plastic bottle fragments in the material discharging hopper 4 fall into the screw conveyor 5 installed at the bottom. The screw conveyor 5 transports the fragments smoothly along the conveying pipeline through the rotation of the screw blades. The fragments fall from the material discharging opening of the screw conveyor 5 and enter the ultrasonic cleaning tank 6 below;

[0047] After the plastic bottle fragments enter the ultrasonic cleaning tank 6, the ultrasonic cleaning tank 6 starts, and the fragments are cleaned by the cavitation effect of ultrasonic waves. At the same time, the stirring and conveying device 71 starts to work. The second motor 702 drives the rotating rod 703 to rotate, and the baffle 704 on the outer wall of the rotating rod 703 stirs the cleaning liquid and the plastic bottle fragments accordingly. The fan-shaped feeding rack 706 on the other side rotates driven by the motor at its input end, further enabling the fragments to fully tumble and disperse in the cleaning liquid, improving the cleaning effect. As the cleaning progresses, the cleaning liquid will gradually become dirty. When it is necessary to discharge the cleaning liquid, the filter element 72 starts to work. The first motor 709 starts, and its output shaft drives the rotating shaft 719 to rotate through a coupling. The worm wheel 720 on the rotating shaft 719 rotates accordingly, and the worm 710 engaged with the worm wheel 720 also starts to rotate. The moving blocks 711 sleeved on the outer walls on both sides of the worm 710 move along the worm 710 under the rotation of the worm 710. The L-shaped rod 712 on the top of the moving block 711 drives the baffle 713 to move. Since the L-shaped rod 712 is threadedly connected to the baffle 713, the position of the baffle 713 can be precisely controlled. When the baffle 713 is opened, the cleaning liquid flows into the water storage tank 716 through the first pipeline 715. In the water storage tank 716, the cleaning liquid first passes through the filter plate 717, and the filter plate 717 filters out the solid impurities in the cleaning liquid. The oil absorption plate 718 located below the filter plate 717 adsorbs the oil stains in the cleaning liquid. The cleaning liquid after filtration and oil removal is recycled back to the ultrasonic cleaning tank 6 through the second pipeline 714, realizing the recycling of the cleaning liquid.
