Description

Technical Field

[0001] The invention relates to the technical field of polytetrafluoroethylene particle recovery, in particular to a polytetrafluoroethylene particle recovery device. Background Art

[0002] Due to its excellent properties, the use and usage of polytetrafluoroethylene in various fields are constantly increasing. Correspondingly, the waste products generated by polytetrafluoroethylene materials are also increasing.

[0003] During the production process of polytetrafluoroethylene, some defective products, scraps and processing waste will be generated. These wastes can usually be recycled and reused to reduce resource waste. At the same time, some polytetrafluoroethylene products will fail due to wear, aging and other reasons after a period of use. These failed products will be pre-treated and then collected in granular form.

[0004] In actual application, some existing polytetrafluoroethylene particle recovery devices are mostly used for single cleaning operation because the discarded polytetrafluoroethylene particles are mixed with some debris, dust and waste materials attached to the surface of the particles when they are discharged. These materials are not screened and collected in an orderly manner. Since the waste particles decomposed after cleaning are of different sizes, the subsequent screening and collection process of the waste and particle materials is relatively cumbersome, which often results in unprocessed waste particles entering the next process, affecting the overall recovery effect and the production quality cannot be guaranteed.

[0056] Reference Figure 10-17The recovery roller mechanism 6 includes an arc plate 61, a transmission gear 62, a bearing member 63, a filter cartridge 64, and a hollow shaft 65, wherein multiple groups of arc plates 61 are installed on the outside of the filter cartridge 64, and multiple groups of vertical rectangular grooves are opened in the middle of the arc plate 61 to circulate liquid, and a hollow shaft 65 is installed at one end of the filter cartridge 64, one end of the hollow shaft 65 is rotatably connected to the processing box 2 and extends out of the processing box 2 and is installed with a transmission gear 62, and the other end of the filter cartridge 64 is open and rotatably installed on one side of the inner wall of the processing box 2 through a bearing member 63.

[0057] Among them, filter cartridge 27 is fixedly installed on one side of the interior of filter cartridge 1 64, a flow groove 271 is opened on the upper part of filter cartridge 27, and one end of filter cartridge 27 is fixedly connected to filter cartridge 1 64, and the other end is open and rotatably installed on one side of the inner wall of the processing box 2 through bearing member 1 63. At this point, filter cartridge 1 64 and filter cartridge 27 rotate synchronously and are jointly installed on bearing member 1 63 to realize rotation operation.

[0058] Furthermore, a recovery cartridge 7 is installed at the inner center of the filter cartridge 27, one end of which is fixedly connected to the processing box 2 and extends out of the processing box 2 and is provided with a discharge trough 74, and the other end is rotatably connected to one side of the inner part of the filter cartridge 64 through a bearing 76;

[0059] A cavity is provided in the middle of the recovery cylinder 7, a feed port 30 is provided on the upper part of the cavity, a guide frame 73 is installed on the upper part of the feed port 30, a slot is provided in the middle of the guide frame 73 and is connected to the feed port 30, and a spiral blade 75 is installed inside the recovery cylinder 7 through a drive shaft 72;

[0060] The guide frame 73 is used to guide and recover the materials scraped off the surface of the filter cartridge 27.

[0061] Among them, one end of the driving shaft 72 extends out of the recovery cylinder 7 and passes through the filter cylinder 64, and extends into the hollow shaft 65 and passes through the outside of the processing box 2 together with the hollow shaft 65, and a transmission gear 71 is installed at one end of the driving shaft 72. Conversely, the other end of the driving shaft 72 is rotatably installed on one side of the interior of the recovery cylinder 7, and a discharge trough 74 is opened on one side of the bottom end of the interior of the recovery cylinder 7.

[0062] Furthermore, a scraper 28 is rotatably installed above the filter cartridge 27, and a certain gap is left between the bottom end of the scraper 28 and the outer surface of the filter cartridge 27, and both ends of the scraper 28 are rotatably installed on both sides of the inner wall of the processing box 2 through a rotating shaft, and one end of the scraper 28 is driven and connected to the micro motor 26, and the micro motor 26 is installed inside the processing box 2.

[0063] There is a gap between the outer wall of the second filter cartridge 27 and the inner wall of the first filter cartridge 64, and a second scraper 28 is installed in the gap area.

[0064] Furthermore, a recovery cartridge 28 is disposed below the filter cartridge 27. The recovery cartridge 28 has the same installation structure as the recovery cartridge 1 7. Since one end of the filter cartridge 27 and the filter cartridge 1 64 is open and rotatably installed inside the treatment box 2 through the bearing member 1 63, the recovery cartridge 28 extends out of the treatment box 2 without interfering with the filter cartridge 27 and the filter cartridge 1 64.

[0065] Among them, a second feed port 31 is opened on the upper part of the second recovery cylinder 8, and a scraper 83 is arranged on one side of the upper part of the second feed port 31. The scraper 83 squeezes and rubs with the outer wall of the bottom side of the second filter cylinder 27.

[0066] Among them, a planetary gear 81 is rotatably installed on the other end of the recovery barrel 8, and a driving shaft 85 is fixedly connected to the middle part of the planetary gear 81. One end of the driving shaft 85 extends into the interior of the recovery barrel 8 and is rotatably installed on one side of the interior of the recovery barrel 8, wherein a spiral blade 84 is installed on the driving shaft 85, and a discharge trough 82 is opened on one side of the inner bottom end of the recovery barrel 8.

[0067] In addition, an inner gear ring 29 is provided on one side of the inner wall of the filter cartridge 1 64, and a planetary gear 81 is connected to the inner gear ring 29 through tooth groove meshing transmission. When the filter cartridge 1 64 rotates, the inner gear ring 29 rotates to drive the planetary gear 81 to synchronously drive the second drive shaft 85 to rotate.

[0068] Reference Fig.10 , 18 A driving motor 17 is installed on one side of the outside of the processing box 2, and the output ends of the driving motor 17 are fixedly connected to a driving gear disc 171 and a driving gear disc 2 172, wherein one side of the driving gear disc 171 and the driving gear disc 2 172 are respectively driven by a transmission gear 1 62 and a transmission gear 2 71 through tooth groove meshing.

[0069] In this embodiment, waste polytetrafluoroethylene particles and pre-treated polytetrafluoroethylene product fragments are selected, and these waste particles are introduced into the crushing chamber 3 through the feed hopper 4. The crushing chamber 3 is provided with a crushing chamber 11 and a crushing mechanism 12. Under the crushing action of the crushing mechanism 12, the waste particles are further crushed into finer particles to facilitate subsequent processing.

[0070] Then, the waste particles enter the guide channel 14 through the discharge trough 13 set at the bottom of the crushing chamber 11. The guide channel 14 is Y-shaped and guides the waste particles to the discharge pipe 15. The electric-driven auger conveying mechanism 20 set in the discharge pipe 15 runs and lifts the material from the bottom to the discharge port 151 at the top through spiral transmission. At this time, the waste particles are discharged and fall into the processing box 2. A cleaning liquid for cleaning polytetrafluoroethylene particles is poured into the processing box 2. Synchronously, the water pump 22 conveys part of the cleaning liquid in the box through the circulating water pipe 51 to the spray nozzle 52 for spraying. At this time, the cleaning liquid is continuously circulated from top to bottom and poured into the processing box 2, and impacts the continuously discharged waste particles. Under the natural fall of the material and the action of the spray nozzle 52, the waste particles are impacted to the bottom guide slope 16 of the processing box 2, and under the action of the continuous jetting of the cleaning liquid driven by the air nozzle 18, the waste particles gradually move forward and gradually float up due to the characteristics of the polytetrafluoroethylene material.

[0071] Furthermore, a separation screen 191 is installed in the middle of the processing box 2. The separation screen 191 preliminarily filters the large particle impurities in the waste particles to prevent them from rising to the upper part of the processing box 2 due to the influence of water flow. Due to the material characteristics of the large particle impurities, they slowly sink to the bottom and are separated from the polytetrafluoroethylene particles.

[0072] The polytetrafluoroethylene particles pass through the separation screen 191 and slowly rise, and move toward the side of the recovery roller mechanism 6 under the action of the water flow.

[0073] Furthermore, the driving motor 17 runs and drives the filter cartridge 64 and the spiral blade 75 to rotate through the corresponding transmission mechanism.

[0074] Among them, the filter cartridge 1 64 rotates synchronously with the arc plate 61 and the filter cartridge 2 27, wherein the arc plate 61 scoops up the polytetrafluoroethylene particles floating nearby, and lifts the materials to the top under the action of rotation and naturally falls on the top position of the filter cartridge 1 64, at this time, the large particles in the polytetrafluoroethylene particles are separated again, so that the small and medium particles pass through the filter cartridge 1 64, and the large particles are retained on the arc plate 61, and the arc plate 61 is provided with corresponding gaps to discharge excess moisture, and as the arc plate 61 rotates, the large particles fall and are thrown into the collection frame 23 for collection.

[0075] Furthermore, small and medium-sized particles fall from the top of filter cartridge 1 64 to the top side of filter cartridge 2 27 inside it, and with continued rotation, the material will continue to fall on the surface of filter cartridge 27 and the gap between filter cartridge 1 64 and filter cartridge 27. At this time, scraper 28 arranged at the gap blocks the medium-sized particles, while small particles pass through the reserved gap.

[0076] Among them, the medium-sized particle materials are blocked by the scraper 28 and slowly accumulated until they fall through the flow groove 271 opened on the surface of the filter cartridge 27. The flow groove 271 guides the medium-sized particle materials blocked by the scraper 28 to be recovered to the recovery cylinder 7 provided inside the filter cartridge 27. The recovery cylinder 7 is provided with a spiral blade 75 to transport the medium-sized particles, and the materials are discharged through the discharge groove 74.

[0077] Furthermore, the fine particles are not affected by the scraper 28 and continue to rotate with the filter cartridge 27, and due to the surface tension formed by the fusion of the fine particle material and the cleaning liquid, they are attached to the filter cartridge 27. When the fine particle material passes through the recovery cartridge 8 on the bottom side, the scraper 83 arranged on the recovery cartridge 8 will scrape off the fine material attached to the filter cartridge 27, and make it fall into the recovery cartridge 8 through the feed port 31, and under the conveying action of the spiral blade 84, it is discharged through the discharge trough 82 to complete the collection of the fine particle material.

[0078] Among them, the spiral blade 2 84 is fixedly connected to the driving shaft 2 85, one end of the driving shaft 2 85 passes through the recovery cylinder 2 8 and is connected to the planetary gear 81. As the filter cylinder 1 64 continues to rotate, the inner gear ring 29 arranged on the inner wall of the filter cylinder 1 64 rotates synchronously, and the planetary gear 81 rotates through the tooth groove meshing transmission, that is, the driving shaft 2 85 rotates.

[0079] Furthermore, since a groove and a separation net 21 are provided on one side of the bottom of the guide slope 16, the cleaning liquid in the processing box 2 continuously flows to the separation net 21 and enters the circulation chamber 25 in the guide slope 16, and cooperates with the water pump 22 arranged inside to complete the circulating water supply. As the water in the box body continues to flow, and cooperates with the guide slope 16 and the air nozzle 18, the water flow continues to flow and drives the separated waste particles to flow to the side of the discharge port 10, and completes the discharge purpose of the waste particles through the discharge port 10.

[0080] In actual use, the inclination angle of the scraper 28 can be changed by controlling the micro motor 26, thereby changing the distance between the bottom end of the scraper 28 and the surface of the filter cartridge 27, thereby changing the size of the recovered medium-sized particle material.

[0081] In actual use, the air nozzle 18 is connected to the external air pump through the connecting air pipe 24, and sprays high-speed gas at the bottom of the processing box 2 to drive the flow of cleaning liquid in the box. The turbulence generated by the gas flow can effectively clean the material.

[0082] Among them, in actual use, a bearing member 2 76 is provided on one side of the interior of the filter cartridge 1 64. The setting of the bearing member 2 76 ensures that the rotation of the filter cartridge 1 64 will not interfere with the recovery cartridge 1 7, and the connection between the two can be guaranteed.

[0083] Among them, in actual use, the driving motor 17 is operated to drive the driving gear plate 171 and the driving gear plate 2 172 to rotate, and the driving gear plate 171 and the driving gear plate 2 172 rotate and rotate through the tooth groove engagement transmission side of the driving gear 1 62 and the driving gear 2 71, and the driving gear 1 62 and the driving gear 2 71 synchronously drive the hollow shaft 65 and the driving shaft 1 72 to rotate, thereby realizing the hollow shaft 65 driving the filter cartridge 1 64 and the filter cartridge 2 27 to rotate, and the driving shaft 1 72 drives the spiral blade 1 75 to rotate, wherein the driving shaft 1 72 is sleeved inside the hollow shaft 65.

[0084] In the actual use process, the partition plate 19 can separate the materials just discharged from the discharge port 151 to ensure the orderliness of material discharge.

[0085] Among them, it is worth noting that the aperture of the separation screen 191 is larger than the aperture of the filter cartridge 64, and the aperture of the filter cartridge 64 is larger than the aperture of the filter cartridge 27, so that the recovered particles are screened in multiple stages through the separation screen 191, the filter cartridge 64, and the filter cartridge 27. At the same time, the aperture of the filter cartridge 27 is the smallest, and fine particles cannot pass through.

[0086] Among them, it is worth noting that the crushing mechanism 12 specifically includes a fixed knife group and a movable knife group, and when the movable knife group is driven by the built-in motor to rotate at a high speed, it cooperates with the fixed knife group to perform preliminary crushing on the material. The specific structural parts and crushing principles of the crushing mechanism 12 that are not described in detail above are already existing technologies, so they will not be elaborated here.

[0087] Among them, it is worth noting that the electric-driven auger conveying mechanism 20 is specifically a conveying mechanical equipment that uses a screw transmission device to transport materials from one location or equipment to another location or equipment. Its power source is a built-in motor component, which is already a prior art and will not be elaborated here. The material in the discharge pipe 15 is lifted and transported by auger conveying.

[0088] In the present invention, after the polytetrafluoroethylene particles are initially processed and crushed, they enter the processing box 2 for cleaning operation. During cleaning, the waste particles are screened by the separation screen 191 and the air nozzle 18, and the polytetrafluoroethylene particles are floated to the top and are scooped up and recovered by the recovery roller mechanism 6. A multi-stage screen and a spiral conveying mechanism are arranged in the recovery roller mechanism 6, which can effectively grade, screen and convey large, medium and small particles, thereby ensuring the recovery effect of the material particles, avoiding impurity doping, and improving the production quality.

[0089] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
