Description

Technical Field

[0001] This invention relates to the field of fluororubber waste recycling, and in particular to a fluororubber waste processing apparatus and processing method. Background Technology

[0002] Against the backdrop of increasingly stringent environmental policies and a surge in demand for resource recycling, fluororubber waste processing equipment utilizes crushing and screening technologies to realize the resource utilization of waste, reduce environmental pollution, promote the industry's green and low-carbon transformation, and align with the sustainable development strategy.

[0003] The core function of existing fluororubber waste processing equipment is to control particle size distribution and efficiently remove impurities through physical crushing and screening technology. After processing, the waste is transformed into recycled particles with uniform particle size, which can be directly used in the production of rubber products. This reduces reliance on virgin materials and reduces solid waste accumulation, thus contributing to a green circular economy. However, when the initial size of different batches of fluororubber waste to be processed varies greatly, using the same crushing method in the crushing device can easily lead to large pieces of material not being sufficiently refined, resulting in a wide particle size distribution and poor uniformity of the recycled particles. When encountering situations where the initial size of different batches of fluororubber waste to be processed varies greatly, it is necessary to manually adjust parameters such as the feed speed, motor speed, and crushing time of the crushing device based on experience. This not only places high demands on the workers but also results in long equipment downtime. Summary of the Invention

[0009] The first conveyor belt is located at the lower end of the screen in the vibrating screening device, and the first conveyor belt and the second conveyor belt are connected to a main conveyor belt at the same end.

[0010] A guide column is located at one end of the main conveyor belt near the crushing device. A second guide frame is fixedly connected to the guide column, with the upper end of the second guide frame facing the main conveyor belt. A spiral blade is rotatably connected inside the guide column.

[0011] A second support frame is provided below the first guide frame, the second conveyor belt is installed on the second support frame, and a second motor is installed on the second support frame to drive the second conveyor belt.

[0012] The first guide frame is provided with a track body, and the bottom of the adjustment plate is fixedly connected to a track block. The adjustment plate and the track block are slidably connected in the track body. A servo motor is installed at the bottom of the first guide frame, and a threaded rod is fixedly connected to the output end of the servo motor. The threaded rod is threadedly connected to the track block.

[0013] The guide column is rotatably connected to a rotating shaft, and the spiral blades are fixedly connected to the outer peripheral wall of the rotating shaft. A third motor is installed at the bottom of the guide column, and the bottom of the rotating shaft is fixedly connected to the output end of the third motor. The third motor is used to drive the spiral blades. A return port is provided at the connection between the guide column and the second guide frame. An outlet is provided at the position of the guide column corresponding to the conical feed port. A fixing frame is installed at the bottom of the guide column and the fixing frame is fixed to the ground.

[0014] The lower end of the screen in the vibrating screening device is fixedly connected to a conical discharge frame, and qualified fluororubber particles screened by the screen are collected from the bottom of the conical discharge frame.

[0015] The crushing device is equipped with a support frame body at the bottom, and a support rod is fixedly connected between the support frame body and the guide column.

[0016] The vibrating screening device has a first support frame installed at the lower end of the screen, the first conveyor belt is installed on the first support frame, and a first motor is installed on the first support frame to drive the first conveyor belt.

[0017] A main support frame is installed in front of the crushing device and the vibrating screening device. The main conveyor belt is installed on the main support frame, and a main motor is installed on the main support frame to drive the main conveyor belt.

[0018] A mounting frame is fixedly connected to the first feed frame, and the laser particle size analyzer is mounted on the mounting frame with the monitoring end of the laser particle size analyzer facing the inner wall of the guide plate of the first feed frame.

[0019] A fluororubber waste processing device and processing method thereof, comprising the following steps:

[0020] Step 1: The feeding device collects the fluororubber waste into the conical feed inlet of the crushing device. The crushing device crushes the fluororubber waste. After crushing, the fluororubber waste flows through the first guide frame 8. The laser particle size analyzer monitors the particle size distribution of the fluororubber particles in the first guide frame in real time and transmits the monitoring data to the central controller for analysis.

[0021] Step 2: If the particle size of the crushed fluororubber waste does not meet the preset standard, the servo motor drives the adjusting plate to retract, directly guiding the unqualified fluororubber particles onto the second conveyor belt. At the same time, the central controller reduces the feeding speed of the feeding device, and the laser particle size analyzer monitors the particle size distribution of the fluororubber particles in the first guide frame in real time. If the particle size of the crushed fluororubber waste still does not meet the preset standard, the unqualified fluororubber particles are directly guided onto the second conveyor belt. Meanwhile, the central controller extends the crushing time of the fluororubber waste in the crushing device until the particle size of the crushed fluororubber waste reaches the preset standard. The fluororubber particles smoothly pass through the first guide frame and enter the vibrating screening device. Qualified fluororubber particles pass through the screen in the vibrating screening device and are collected through the conical discharge frame. Unqualified fluororubber particles slide off the screen onto the first conveyor belt.

[0022] Step 3: The fluororubber particles on the first and second conveyor belts are collected onto the main conveyor belt. The main conveyor belt guides the fluororubber particles into the guide column through the return port. The third motor at the bottom of the guide column drives the rotating shaft to rotate, and the rotating shaft drives the spiral blades fixedly connected to it to rotate. The spiral blades guide the fluororubber particles in the guide column into the conical feed port of the crushing device.

[0023] The technical effects and advantages of this invention are as follows:

[0024] 1. The fluororubber waste processing device and its processing method adopt a structure in which a first guide frame is set between the crushing device and the vibrating screening device. A laser particle size analyzer is installed above the first guide frame. The monitoring end of the laser particle size analyzer is directly facing the inner wall of the guide plate of the first guide frame. The laser particle size analyzer uses the principle of laser scattering to monitor the particle size distribution of fluororubber particles in the guide frame in real time. When encountering a situation where the initial size difference of different batches of fluororubber waste to be processed is large, the central controller dynamically adjusts the feeding speed and crushing time of the crushing device according to the detection data of the laser particle size analyzer until the preset particle size is reached. On the one hand, it reduces the requirements for workers, and on the other hand, the dynamic adjustment can effectively shorten the downtime of the equipment.

[0025] 2. This fluororubber waste processing device, through the installation of a first conveyor belt, a second conveyor belt, and a main conveyor belt, allows the second conveyor belt to transport unqualified particles to the main conveyor belt when the central controller adjusts the crushing device parameters. The first conveyor belt transports unqualified particles after screening by the vibrating screening device to the main conveyor belt, and the main conveyor belt transports the unqualified particles to the guide column. The unqualified particles are then reintroduced into the crushing device by the rotation of the spiral blades. This design enables unmanned operation and effectively reduces the workload of workers.

[0035] 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.

[0036] This invention provides, for example Figure 1 - Figure 7 The apparatus shown includes:

[0037] The crushing device 1 has a conical feed inlet 101 fixedly connected to its upper end. The crushing device 1 is the core crushing unit. It fully crushes the fluororubber waste into smaller particles through rotating blades, preparing it for subsequent screening and reuse. The fluororubber waste enters the crushing device 1 from the conical feed inlet 101 and is crushed by the internal crushing components inside the crushing device 1.

[0038] Vibrating screening device 2 is installed downstream of the output end of crushing device 1. Vibrating screening device 2 screens the crushed fluororubber particles, separating particles that meet the particle size requirements from those that are unqualified. The crushed fluororubber particles enter the vibrating screening device 2 after being output from crushing device 1. Vibrating screening device 2 causes the particles to roll on the screen through vibration. Qualified particles smaller than the screen aperture pass through the screen, while unqualified particles larger than the screen aperture remain on the screen. Vibration conveys the unqualified particles on the screen to the first conveyor belt 5. The first conveyor belt 5 conveys the unqualified particles screened by vibrating screening device 2 to the main conveyor belt 4. The main conveyor belt 4 conveys the unqualified particles to the guide column 9. The rotating spiral blades 12 guide the unqualified particles back into crushing device 1. Vibrating screening device 2 causes the particles to roll on the screen through vibration. Qualified particles pass through the screen and are collected by the conical discharge frame 201; unqualified particles remain on the screen and are transmitted to the first conveyor belt 5 through vibration, initiating the unqualified particle return process.

[0039] The first feed frame 8 is fixedly connected at its upper end to the output end of the crushing device 1, and its lower end is aligned with the feed port of the vibrating screening device 2. A laser particle size analyzer 3 is installed above the first feed frame 8. The laser particle size analyzer 3 uses the principle of laser scattering to monitor the particle size distribution of fluororubber particles in the first feed frame 8 in real time, providing data for the central controller to adjust the parameters of the crushing device 1. When the laser beam penetrates the fluororubber particle suspension in the feed frame, the particles act as diffractors, causing the laser to scatter. The propagation direction of the scattered light forms an angle θ with the main beam, and the size of the angle is inversely proportional to the particle size—the larger the particle size, the smaller the angle θ; the smaller the particle size, the larger the angle θ. At the same time, the intensity of the scattered light at a specific angle directly reflects the proportion of particles of that size. The instrument focuses the scattered light onto a ring photodetector array on the back focal plane through a Fourier lens. Detectors at different positions correspond to different scattering angles, thereby capturing light energy distribution data across the entire angular range. After these data are converted into digital signals by a high-speed data acquisition card, they are inverted and calculated by dedicated software based on Fraunhofer diffraction theory or Mie scattering theory. The light energy distribution is converted into a particle size distribution curve. The system can complete hundreds of cyclic scans per second, output key parameters such as D50 median diameter and D97 coarse end particle size in real time, and generate a particle size distribution histogram, providing accurate data support for the online control of fluororubber pulverization process.

[0040] An adjusting plate 13 is slidably connected inside the first guide frame 8. A second conveyor belt 6 is located directly below the adjusting plate 13. The first guide frame 8 guides the fluororubber particles output from the crushing device 1 to the feeding port of the vibrating screening device 2, and provides an installation position for the laser particle size analyzer 3. The adjusting plate 13 inside can control the flow direction of the particles. When the central controller adjusts the parameters of the crushing device 1, the unqualified particles generated open the adjusting plate 13. The servo motor 16 drives the threaded rod 15 to rotate, causing the track block 14 and the adjusting plate 13 to slide within the track body 801, thereby controlling the flow direction of the particles in the first guide frame 8. The unqualified particles fall onto the second conveyor belt 6, which transfers them to the main conveyor belt 4. The main conveyor belt 4 transfers the unqualified particles to the guide column 9, where the rotating spiral blades 12 guide the unqualified particles back into the crushing device 1.

[0041] The first conveyor belt 5 is located at the lower end of the screen in the vibrating screening device 2. The first conveyor belt 5 and the second conveyor belt 6 are connected to a main conveyor belt 4 at the same end.

[0042] The guide column 9 is located at one end of the main conveyor belt 4 near the crushing device 1. A second guide frame 10 is fixedly connected to the guide column 9, with its upper end facing the main conveyor belt 4. A spiral blade 12 is rotatably connected inside the guide column 9. The guide column 9 receives unqualified particles from the main conveyor belt 4 and guides them back into the crushing device 1 through the internal spiral blade 12. The second guide frame 10 is fixedly connected to the guide column 9, with its upper end facing the main conveyor belt 4. The guide column 9 is rotatably connected to a spiral blade 12. A return port 904 is provided at the connection between the guide column 9 and the second guide frame 10. A discharge port 903 is provided at the position of the guide column 9 corresponding to the conical feed port 101. A fixing frame 901 is installed at the bottom of the guide column 9 and fixed to the ground. Unqualified particles enter the second guide frame 10 from the main conveyor belt 4, and then enter the guide column 9 through the return port 904. After being conveyed by the spiral blade 12, they enter the conical feed port 101 from the discharge port 903.

[0043] A second support frame 601 is provided below the first guide frame 8. The second conveyor belt 6 is installed on the second support frame 601. A second motor 602 is installed on the second support frame 601. The second motor 602 is used to drive the second conveyor belt 6 to realize particle conveying.

[0044] The first guide frame 8 is equipped with a track body 801. The bottom of the adjustment plate 13 is fixedly connected to the track block 14. The adjustment plate 13 and the track block 14 are slidably connected in the track body 801. The bottom of the first guide frame 8 is equipped with a servo motor 16. The output end of the servo motor 16 is fixedly connected to a threaded rod 15. The threaded rod 15 is threadedly connected to the track block 14.

[0045] A rotating shaft 11 is rotatably connected inside the guide column 9. The spiral blade 12 is fixedly connected to the outer peripheral wall of the rotating shaft 11. A third motor 17 is installed at the bottom of the guide column 9. The bottom of the rotating shaft 11 is fixedly connected to the output end of the third motor 17. The third motor 17 is used to drive the spiral blade 12.

[0046] A return port 904 is provided at the connection between the guide column 9 and the second guide frame 10. A discharge port 903 is provided at the position of the guide column 9 corresponding to the conical feed port 101. A fixing frame 901 is installed at the bottom of the guide column 9 and is fixed to the ground.

[0047] The bottom of the crushing device 1 is equipped with a support frame body 7, and a support rod 902 is fixedly connected between the support frame body 7 and the guide column 9.

[0048] The vibrating screening device 2 has a first support frame 501 installed at the lower end of the screen, a first conveyor belt 5 installed on the first support frame 501, and a first motor 502 installed on the first support frame 501. The first motor 502 is used to drive the first conveyor belt 5 to realize particle conveying.

[0049] A main support frame 401 is installed in front of the crushing device 1 and the vibrating screening device 2. The main conveyor belt 4 is installed on the main support frame 401. A main motor 402 is installed on the main support frame 401. The main motor 402 is used to drive the main conveyor belt 4 to realize particle conveying.

[0050] A mounting bracket 301 is fixedly connected to the first feed frame 8. The laser particle size analyzer 3 is mounted on the mounting bracket 301, and the monitoring end of the laser particle size analyzer 3 is directly facing the inner wall of the guide plate of the first feed frame 8.

[0051] A conical discharge frame 201 is fixedly connected to the lower end of the screen in the vibrating screening device 2. The conical discharge frame 201 can collect qualified fluororubber particles that have passed through the screen of the vibrating screening device 2, which is convenient for subsequent centralized collection. The qualified fluororubber particles that have passed through the screen are collected from the bottom of the conical discharge frame 201.

[0052] In practical applications, when encountering situations where different batches of fluororubber waste have significant differences in initial size, the fluororubber waste first enters the crushing device 1 through the conical feed inlet 101 for preliminary crushing. The crushed particles then enter the first guide frame 8. At this time, the laser particle size analyzer 3, mounted on the mounting bracket 301 on the first guide frame 8, uses the principle of laser scattering to monitor the particle size distribution of the fluororubber particles in the first guide frame 8 in real time and transmits the data to the central controller. The central controller dynamically adjusts parameters such as the feeding speed, motor speed, and crushing time of the crushing device 1 based on the detection data. Simultaneously, it drives the threaded rod 15 to rotate via the servo motor 16, causing the adjusting plate 13 to slide within the track body 801, adjusting the flow direction of unqualified particles in the first guide frame 8 until the preset particle size is achieved. This process reduces the requirements for operators, and the dynamic adjustment effectively shortens the equipment downtime.

[0053] Figure 8 A processing device and method for fluororubber waste, comprising the following steps:

[0054] Step 1: The feeding device collects the fluororubber waste into the conical feed inlet 1 of the crushing device 1. The crushing device 1 crushes the fluororubber waste. After crushing, the fluororubber waste flows through the first guide frame 8. The laser particle size analyzer 3 monitors the particle size distribution of the fluororubber particles in the first guide frame 8 in real time and transmits the monitoring data to the central controller for analysis.

[0055] Step 2: If the particle size of the crushed fluororubber waste does not meet the preset standard, the servo motor 16 drives the adjusting plate 13 to retract, directly guiding the unqualified fluororubber particles onto the second conveyor belt 6. At the same time, the central controller reduces the feeding speed of the feeding device, and the laser particle size analyzer 3 monitors the particle size distribution of the fluororubber particles in the first guide frame 8 in real time. If the particle size of the crushed fluororubber waste still does not meet the preset standard, the unqualified fluororubber particles are directly guided onto the second conveyor belt 6. At the same time, the central controller extends the crushing time of the fluororubber waste in the crushing device 1 until the particle size of the crushed fluororubber waste reaches the preset standard. The fluororubber particles smoothly pass through the first guide frame 8 and enter the vibrating screening device 2. The qualified fluororubber particles pass through the screen in the vibrating screening device 2 and are collected by the conical discharge frame 201. The unqualified fluororubber particles slide off the screen onto the first conveyor belt 5.

[0056] Step 3: The fluororubber particles on the first conveyor belt 5 and the second conveyor belt 6 are collected onto the main conveyor belt 4. The main conveyor belt 4 guides the fluororubber particles into the guide column 9 through the return port 904. The third motor 17 at the bottom of the guide column 9 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the spiral blade 12 fixedly connected to it to rotate. The spiral blade 12 guides the fluororubber particles in the guide column 9 into the conical feed port 1 of the crushing device 1.

[0057] Example 1: To achieve precise control of the parameters of the crushing device 1, a laser particle size analyzer 3 is installed above the first guide frame 8. The upper end of the first guide frame 8 is fixed to the output end of the crushing device 1, and the lower end is aligned with the feeding port of the vibrating screening device 2. Its function is to guide the crushed fluororubber particles to the vibrating screening device 2, and at the same time provide an installation position for the laser particle size analyzer 3. The laser particle size analyzer 3 works based on the principle of laser scattering. When the laser beam penetrates the fluororubber particles in the first guide frame 8, the particles act as diffractors, causing the laser to scatter. The direction of the scattered light propagation forms an angle θ with the main beam. The size of the angle is inversely proportional to the particle size. The intensity of the scattered light at a specific angle reflects the proportion of particles of that size. The instrument focuses the scattered light onto a ring photodetector array on the back focal plane through a Fourier lens. Different detector positions correspond to different scattering angles, capturing full-angle light energy distribution data. After these data are converted into digital signals by a high-speed data acquisition card, they are inverted and calculated by dedicated software based on Fraunhofer diffraction theory or Mie scattering theory, converting the light energy distribution into a particle size distribution curve.

[0058] The system can perform hundreds of cyclic scans per second, outputting key parameters such as the median diameter (D50) and coarse-end particle size (D97) in real time, and generating a particle size distribution histogram. The central controller uses this data to determine the pulverization effect. If the particle size does not meet the requirements, it promptly adjusts parameters such as the rotation speed of the pulverizing device 1 and the pulverization time to ensure that the pulverized fluororubber particles meet the requirements for subsequent screening and reuse, thereby improving the quality and efficiency of recycling.

[0059] Example 2: In this fluororubber waste processing device, a recirculation and reprocessing mechanism is set up for the unqualified fluororubber particles generated after crushing and screening. The crushing device 1 crushes the fluororubber waste through rotating blades, and the crushed particles enter the vibrating screening device 2 through the first guide frame 8. The vibrating screening device 2 causes the particles to roll on the screen through vibration. Qualified particles smaller than the screen aperture pass through the screen and are collected by the conical discharge frame 201; unqualified particles larger than the screen aperture remain on the screen and are conveyed to the first conveyor belt 5 by vibration. An adjusting plate 13 is slidably connected in the first guide frame 8. When the central controller adjusts the parameters of the crushing device 1 according to the monitoring data of the laser particle size analyzer 3, the unqualified particles generated can be removed by opening the adjusting plate 13. The servo motor 16 drives the threaded rod 15 to rotate, causing the track block 14 and the adjusting plate 13 to slide in the track body 801, so that the unqualified particles fall onto the second conveyor belt 6. The first conveyor belt 5 and the second conveyor belt 6 are connected at the same end to the main conveyor belt 4. Unqualified particles are transported to the main conveyor belt 4 via the first conveyor belt 5 and the second conveyor belt 6.

[0060] A guide column 9 is provided at one end of the main conveyor belt 4 near the crushing device 1. A second guide frame 10 is fixedly connected to the guide column 9. The upper end of the second guide frame 10 is directly opposite the main conveyor belt 4. A spiral blade 12 is rotatably connected inside the guide column 9. Unqualified particles enter the second guide frame 10 from the main conveyor belt 4, and then enter the guide column 9 through the return port 904. After being conveyed by the spiral blade 12, they enter the conical feed port 101 from the discharge port 903 and are reintroduced into the crushing device 1 for further crushing until the particle size meets the requirements. This realizes the recycling of unqualified particles, improves the recycling rate of fluororubber waste, and reduces resource waste.

10. A fluororubber waste processing device and a processing method thereof, wherein the fluororubber waste processing device according to any one of claims 1-9 is characterized in that, Includes the following steps: Step 1: The feeding device collects the fluororubber waste into the conical feed inlet (1) of the crushing device (1). The crushing device (1) crushes the fluororubber waste. The crushed fluororubber waste flows through the first guide frame 8. The laser particle size analyzer (3) monitors the particle size distribution of the fluororubber particles in the first guide frame (8) in real time and transmits the monitoring data to the central controller for analysis. Step 2: If the particle size of the crushed fluororubber waste does not meet the preset standard, the servo motor (16) drives the adjustment plate (13) to shrink, and the unqualified fluororubber particles are directly introduced into the second conveyor belt (6). At the same time, the central controller reduces the feeding speed of the feeding device, and the laser particle size analyzer (3) monitors the particle size distribution of the fluororubber particles in the first guide frame (8) in real time. If the particle size of the crushed fluororubber waste still does not meet the preset standard, the unqualified fluororubber particles are directly introduced into the second conveyor belt (6). At the same time, the central controller extends the crushing time of the fluororubber waste in the crushing device (1) until the particle size of the crushed fluororubber waste reaches the preset standard. The fluororubber particles pass smoothly through the first guide frame (8) and enter the vibrating screening device (2). The qualified fluororubber particles pass through the screen in the vibrating screening device (2) and are collected by the conical discharge frame (201). The unqualified fluororubber particles slide off the screen onto the first conveyor belt (5). Step 3: The fluororubber particles on the first conveyor belt (5) and the second conveyor belt (6) are collected on the main conveyor belt (4). The main conveyor belt (4) guides the fluororubber particles into the guide column (9) through the return port (904). The third motor (17) at the bottom of the guide column (9) drives the rotating shaft (11) to rotate. The rotating shaft (11) drives the spiral blade (12) fixedly connected to it to rotate. The spiral blade (12) guides the fluororubber particles in the guide column (9) into the conical feed port (1) of the crushing device (1).
