Description

Technical Field

[0001] This invention relates to the field of latex processing technology, specifically to a raw material grinding and filtering device and process for latex processing. Background Technology

[0002] Grinding is a crucial step in latex processing. Its main purpose is to refine and uniformly disperse the particles in the raw materials through mechanical force, thereby improving the performance of the final product. The core function of grinding is to refine and disperse particles. Latex raw materials often contain large particles or agglomerates. The grinding process uses grinding media (such as zirconium beads) in equipment such as sand mills to apply shear and impact forces to the particles, causing them to break down and refine to the micron or even nanometer level. At the same time, it promotes the uniform distribution of fillers, additives and other components in the continuous phase, avoids sedimentation or aggregation, and lays the foundation for subsequent processing.

[0003] Currently, in latex processing, grinding machines are generally used to grind raw materials. To improve the quality of the ground material, it needs to be filtered after grinding. Existing grinding and filtration equipment has a simple structure; on a single production line, there is only one set of filtration equipment after grinding. However, as filtration time accumulates, a large amount of impurities will remain in the filtration equipment. Therefore, to improve filtration, the filtration equipment needs to be cleaned regularly. Since there is only one set of equipment, the production line will stop operating during cleaning, thus affecting production efficiency. Therefore, we propose a raw material grinding and filtration device and process for latex processing. Summary of the Invention

[0018] 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.

[0019] Please see Figures 1-12This invention provides a technical solution: a raw material grinding and filtering device for latex processing, comprising a grinding machine body 1, a discharge pipe 2 connected to the bottom end of the grinding machine body 1, a conveying component 3 connected to the end of the discharge pipe 2, three top covers 4 connected to the conveying component 3, a filter tank 5 installed at the bottom end of the top cover 4, a discharge pipe 16 connected to the bottom end of the filter tank 5, a discharge base 6 provided at the bottom end of the discharge pipe 16, a fixing ring 7 fixedly connected inside the filter tank 5, a filter screen 8 provided on the fixing ring 7, and a rotating shaft 9 rotatably connected to the bottom end of the filter screen 8; and further comprising: a cleaning component 10.

The cleaning component 10 is used to clean the filter screen 8 to prevent impurities from clogging the filter screen 8 and affecting the filtration efficiency. The control component 11 works in conjunction with the conveying component 3. The control component 11 is used to control the grinding material to enter one of the three filter tanks 5. The three filter tubes can filter the grinding material separately. Therefore, when cleaning one set of filter screens 8, the other filter screens 8 can continue to work, so as not to affect the operation of the production line, not to delay the work progress, and not to affect the production efficiency.

[0020] The system is equipped with three filter tanks 5. During the filtration process, the control component 11 controls the grinding material to enter different filter tanks 5 respectively. While one set of filter tanks 5 is being cleaned, the other two sets of filter tanks 5 can continue to be used to filter the material, so the production line will not stop running and the production efficiency is improved. In addition, the cleaning component 10 can clean the filter screen 8 during this process to prevent impurities from clogging the filter screen 8 and affecting the filtration.

[0021] A process for a raw material grinding and filtering device for latex processing includes the following steps: S1: Raw material collection and initial processing: After natural latex is collected from rubber trees, it needs to be initially processed within 2 hours to prevent solidification. Aluminum containers are used for collection to avoid impurities from being mixed in. S2: Filtration and purification: Use an 80-mesh nylon filter to remove bark, impurities, etc.; add 0.3%-0.5% ammonia solution to inhibit microbial growth and prevent coagulation; after filtration, the latex is stored in a sealed storage tank at a constant temperature of 25°C, and stirred for 15 minutes every hour to keep it uniform. S3: Grinding and mixing: Mix natural latex and synthetic latex in a 7:3 ratio, add ammonia to adjust the pH to 10-10.5, add sulfur, zinc oxide and accelerator DM, and stir at a constant temperature of 35℃ for 4 hours to fully disperse the additives.

[0022] In an embodiment of the present invention, please refer to Figure 2 and Figure 4The material conveying component 3 shown in the figure includes a connecting pipe 12 connected to the discharge pipe 2. The end of the connecting pipe 12 is connected to a diversion pipe 13. Three connecting pipes 14 are connected to the diversion pipe 13. The three connecting pipes 14 are slidably connected to three sets of top covers 4 respectively. An elastic element 15 is provided between the top cover 4 and the connecting pipe 14. The elastic element 15 includes a fixing piece 49 fixedly connected to the top cover 4. The fixing piece 49 is slidably connected to the connecting pipe 14. A second spring 50 is fixedly connected to the fixing piece 49 and sleeved on the outer side of the connecting pipe 14. The end of the second spring 50 is fixedly connected to a connecting piece 51 fixedly connected to the connecting pipe 14, which facilitates the conveying of the ground material into the filter tank 5. It also cooperates with the control component 11 to allow the material to enter the different filter pipes respectively.

[0023] After grinding, the material will enter the connecting pipe 12 through the discharge pipe 2, and then be transported to the inside of the connecting pipe 14 through the diversion pipe 13. At this time, the material can be controlled to enter one of the connecting pipes 14 through the control component 11, and then transported to the corresponding filter tank 5 through the connecting pipe 14 to be filtered by the filter screen 8.

[0024] In an embodiment of the present invention, please refer to Figure 3 and Figure 6 The feeding base 6 shown in the figure includes a housing 17 sleeved on the outer side of the feeding pipe 16. A discharge pipe 18 is installed on the housing 17. A collecting pipe 19 is connected to the discharge pipe 18. Three conveying pipes 20 are connected to the collecting pipe 19. The end of the conveying pipe 20 is connected to a connecting pipe 21. The three connecting pipes 21 are inserted into the three feeding pipes 16 to facilitate support of the device and facilitate material discharge.

[0025] The filtered material will enter the feed pipe 16 and be transported to the connecting pipe 21. Then, it will enter the conveying pipe 20 and the collecting pipe 19 through the connecting pipe 21, and finally be discharged through the discharge pipe 18.

[0026] In an embodiment of the present invention, please refer to Figure 2 and Figure 7 The cleaning assembly 10 shown in the figure includes rotating blocks 22 installed inside the three filter screens 8 respectively. Multiple scrapers 23 that are in contact with the inner wall of the filter screen 8 are fixedly connected to the rotating blocks 22. A plug-in block 24 that is inserted into the rotating shaft 9 is fixedly connected to the axis of the rotating blocks 22. The end of the rotating shaft 9 is provided with a plug-in groove 25 that is adapted to the plug-in block 24. The bottom end of the rotating shaft 9 is connected to a rotating component 26 for driving the rotating shaft 9 to rotate, which facilitates cleaning of the filter screens 8 and prevents impurities from clogging the filter screens 8 and affecting filtration. The rotating block 22 is fixedly connected to a vertical rod 52, and the end of the vertical rod 52 is fixedly connected to an operating block 54, which facilitates the removal of the filter screen 8. The vertical rod 52 is also fixedly connected to a connecting frame 53, which is fixedly connected to multiple sets of scrapers 23, which can reinforce the scrapers 23 and make them fit the filter screen 8 better.

[0027] Furthermore, the rotating block 22 is rotated by the action of the rotating component 26, and the rotation of the rotating block 22 causes the scraper 23 to rotate, thereby cleaning the inner wall of the filter screen 8.

[0028] In an embodiment of the present invention, please refer to Figure 7 and Figure 9 The rotating component 26 shown in the figure includes a connecting shaft 27 rotatably connected to the connecting pipe 21. The end of the connecting shaft 27 is fixedly connected to a mating block 28 that is inserted into the rotating shaft 9. A reinforcing member 29 is provided between the mating block 28 and the rotating shaft 9, and a reinforcing member 29 is also provided between the rotating shaft 9 and the inserting block 24. The bottom ends of the three connecting shafts 27 extend to the outside of the connecting pipe 21, and a spur gear 34 is fixedly connected to the end. A driving component 35 is provided between the three spur gears 34 to facilitate the rotation of the scraper 23 to clean the filter screen 8.

[0029] The drive component 35 causes the spur gear 34 to rotate, which in turn drives the connecting shaft 27 to rotate. After the connecting shaft 27 rotates, it will cause the rotating shaft 9 to rotate through the action of the mating block 28 and the rotating shaft 9, which in turn causes the plug-in block 24 to rotate. The rotation of the plug-in block 24 causes the rotating block 22 to rotate.

[0030] In an embodiment of the present invention, please refer to Figures 7-9 The reinforcement component 29 shown in the figure includes a first spring 30 installed inside the plug block 24 and the docking block 28 respectively. The end of the first spring 30 is fixedly connected to a sliding post 31. The two sets of sliding posts 31 are slidably connected to the plug block 24 and the docking block 28 respectively. The end of the sliding post 31 is rotatably connected to a ball 32. The rotating shaft 9 is provided with a groove 33 that matches the ball 32, so that the filter tank 5 can be disassembled and the internal cleaning parts can also be disassembled, and the installation is more stable.

[0031] The rotating shaft 9 can disengage from the docking block 28 and the insertion block 24 through the cooperation of the ball bearing 32, the groove 33 and the spring, which facilitates the disassembly of the filter tank 5 to clean the internal filter screen 8, and the parts connected to the rotating block 22 can be removed from the filter screen 8 for easy replacement of the filter screen 8.

[0032] Furthermore, the connection between the rotating shaft 9 and the mating block 28 and the insertion block 24 can be strengthened through the cooperation of the ball bearing 32, the groove 33 and the spring.

[0033] In an embodiment of the present invention, please refer to Figure 2 and Figure 11 The control component 11 shown in the figure includes a sealing cover 36 installed inside the diversion pipe 13. The sealing cover 36 has a through hole 37, which is corresponding to one of the three connecting pipes 14. The axis of the sealing cover 36 is fixedly connected to a rotating rod 38 that is rotatably connected to the diversion pipe 13. The end of the rotating rod 38 is connected to a one-way rotation control component 39, which is connected to a drive component 35 to facilitate the control of material entering different filter tanks 5.

[0034] The drive unit 35 controls the rotation of the unidirectional rotation control unit 39, which causes the rotation rod 38 to rotate, thereby causing the sealing cover 36 to rotate. The rotation of the sealing cover 36 causes the through hole 37 to rotate, and the through hole 37 can then connect with three different connecting pipes 14. The material after grinding will enter the filter tank 5 through the corresponding connecting pipe 14 that the through hole 37 connects to.

[0035] In an embodiment of the present invention, please refer to Figure 7 and Figure 10 The driving component 35 shown in the figure includes a motor 40 fixed inside the housing 17. The output end of the motor 40 is fixedly connected to a drive shaft 41. A rotating frame 42 is fixedly connected to the drive shaft 41. A gear ring 43 is fixedly connected to the rotating frame 42. The gear ring 43 is meshed with three sets of spur gears 34 to provide stable driving force for the device.

[0036] The control motor 40 starts, causing the drive shaft 41 to rotate. The rotation of the drive shaft 41 will drive the rotating frame 42 to rotate, which in turn causes the gear ring 43 to rotate. The rotation of the gear ring 43 causes the flat gear 34 to rotate.

[0037] In an embodiment of the present invention, please refer to Figure 11 and Figure 12 The unidirectional rotation control component 39 shown in the figure includes a rotating plate 44 fixedly connected to a rotating rod 38. A ratchet 45 is rotatably connected to the rotating plate 44. A pawl 46 meshes with the outer side of the ratchet 45. A rotating column 47 rotatably connected to the rotating plate 44 is fixedly connected to the pawl 46. A torsion spring 48 fixedly connected to the rotating plate 44 is fixedly connected to the rotating column 47, which facilitates the unidirectional rotation control of the sealing cover 36.

[0038] In this scheme, the motor 40 is a forward and reverse motor 40. During the forward rotation of the motor 40, the filter tank 5 normally filters the ground material. During this process, the drive shaft 41 will drive the ratchet 45 to rotate forward. When the ratchet 45 rotates forward, it will disengage from the pawl 46, and the rotating plate 44 will not rotate accordingly. At this time, the position of the through hole 37 will not change. When it is necessary to switch the use of the filter tank 5, the motor 40 is controlled to rotate in reverse. At this time, the reverse rotation of the drive shaft 41 will drive the ratchet 45 to rotate in reverse. At this time, the ratchet 45 will engage with the pawl 46 and drive the rotating plate 44 to rotate. The rotation of the rotating plate 44 drives the sealing cover 36 to rotate, thereby making the through hole 37 rotate to correspond with another set of connecting pipes 14.

[0039] During the process, after the grinding machine body 1 grinds the raw material, the ground material will enter the connecting pipe 12 through the discharge pipe 2. It will be transported to the inside of the diversion pipe 13 through the connecting pipe 12. At this time, the connecting pipe 14 corresponding to the through hole 37 will transport the material to the corresponding filter tank 5. The material will be filtered through the filter screen 8. The filtered material will enter the discharge pipe 16 and be transported to the connecting pipe 21 through the discharge pipe 16. Then, it will enter the conveying pipe 20 and the collecting pipe 19 through the connecting pipe 21. Finally, the filtered material will be discharged through the discharge pipe 18. In the above process, the control motor 40 rotates forward, which drives the drive shaft 41 to rotate, thereby causing the rotating frame 42 to rotate. The rotation of the rotating frame 42 will drive the gear ring 43 to rotate, and the gear ring 43 will cause the spur gear 34 to drive the connecting shaft 27 to rotate, thereby causing the docking block 28 to rotate. The connection between the docking block 28 and the rotating shaft 9 causes the rotating shaft 9 to rotate. Then, the rotating shaft 9 will cause the insertion block 24 to rotate, thereby causing the rotating block 22 to rotate. The rotation of the rotating block 22 will cause the scraper 23 to rotate to clean the filter screen 8, preventing the filter screen 8 from becoming clogged and affecting filtration. Furthermore, after filtering for a period of time, a large amount of impurities remain inside the filter screen 8. At this time, the scraping effect of the scraper 23 on the filter screen 8 is minimal, and the filter screen 8 needs to be cleaned. During this process, the control motor 40 reverses, and the reverse rotation of the drive shaft 41 will drive the ratchet 45 to reverse. At this time, the ratchet 45 will mesh with the pawl 46 to drive the rotating plate 44 to rotate. The rotation of the rotating plate 44 drives the sealing cover 36 to rotate, thereby causing the through hole 37 to rotate and correspond to another set of connecting pipes 14. After that, the ground material will enter another set of filter tanks 5. Furthermore, after switching, unscrew the fixing screws on the top cover 4, then slide the filter tank 5 upwards to disengage the feed pipe 16 from the connecting pipe 21. At this time, the plug block 24 disengages from the rotating shaft 9. Then remove the filter tank 5, and then remove the filter screen 8 to clean it. After cleaning, reinstall the filter tank 5. The process is the reverse of the disassembly process. It is worth noting that when the filter screen 8 needs to be replaced, the rotating block 22 and the parts connected to the rotating block 22 can be pulled out through the operating block 54, so that the filter screen 8 can be replaced separately, while the rotating block 22 and the parts connected to it can continue to be used.
