Abstract
Description
Technical Field
[0001] This utility model relates to the field of PA66 resin separation technology, and in particular to a PA66 resin separation and purification device. Background Technology
[0002] The PA66 resin separation and purification device is designed to effectively separate and purify PA66 resin from a mixture. Based on the differences in the physical or chemical properties of PA66 resin and fillers, appropriate separation methods are used to separate the PA66 resin from the mixture. Larger particles of impurities mixed in the PA66 resin can be separated by physical filtration, that is, by using a filter screen. The diameter of the filter screen is larger than the diameter of the impurities, which can pre-filter the impurities, thus achieving the purpose of pre-purification.
[0003] When separating and purifying PA66 resin, a separate pipeline is often used for its transport. Therefore, the area through which PA66 resin is transported into the purification device is relatively limited, reducing the contact area between the PA66 resin and the filter screen, thereby lowering the filtration efficiency and causing uneven purification due to excessively high local resin concentrations. Therefore, it is particularly important to design a PA66 resin separation and purification device that can comprehensively stir the PA66 resin to be purified, thereby improving the flowability of PA66 resin, and can also scrape off PA66 resin splashed on the inner wall of the device. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution for a PA66 resin separation and purification device:
[0022] Example 1:
[0023] like Figure 1-3 As shown, a PA66 resin separation and purification device includes a purification chamber 1 and a feed pipe 2. The feed pipe 2 is located on one side of the purification chamber 1, and a heating cylinder 3 is located on the other side of the purification chamber 1. A distribution ring 4 is located on the top of the purification chamber 1, and several guide pipes 5 are fixedly connected to the bottom end of the distribution ring 4. A micro motor 6 is located on the top of the heating cylinder 3. A support rod 9 is located on the top of the purification chamber 1, and an auxiliary rod 10 is located inside the support rod 9. A circular sleeve 14 is fitted onto one end of the auxiliary rod 10. The outer wall of the circular sleeve 14 is provided with multiple L-shaped plates 15. The output shaft of the micro motor 6 is connected to the transmission rod 7. An L-shaped tube 12 is provided on one side of the heating cylinder 3. The outer surfaces of the multiple L-shaped plates 15 are in contact with the inner wall of the purification chamber 1, which can scrape off the PA66 resin adhering to its inner wall, thus avoiding the waste of PA66 resin. Several branch rods 16 can stir the PA66 resin in the purification chamber 1. The combined stirring of the two helps to further improve the fluidity of PA66 resin.
[0024] Example 2:
[0025] Based on Example 1, such as Figure 1 and Figure 4 As shown, the circular sleeve 14 is fixedly sleeved to one end of the auxiliary rod 10. Several branch rods 16 are fixedly installed at the bottom of the multiple L-shaped plates 15. The multiple branch rods 16 are arranged at equal intervals. The purification box 1 is equipped with a filter frame 18. This utility model is a PA66 resin separation and purification device. By setting up a support rod 9, belt 11, circular sleeve 14, filter frame 18 and filter screen 19, the auxiliary rod 10 rotates inside the support rod 9, which in turn drives the circular sleeve 14 fixedly sleeved to rotate. The multiple L-shaped plates 15 and the multiple branch rods 16 can rotate synchronously. The multiple branch rods 16 can make circumferential motion inside the filter frame 18.
[0026] Working Principle: The PA66 resin separation and purification device is designed to effectively separate and purify PA66 resin from a mixture. Based on the differences in the physical and chemical properties of PA66 resin and fillers, an appropriate separation method is used to separate the PA66 resin from the mixture. Larger particles of impurities mixed in with the PA66 resin can be separated by physical filtration, that is, by using a filter screen. The diameter of the filter screen is larger than the diameter of the impurities, which allows for pre-filtration of these impurities, thus achieving the purpose of pre-purification. The PA66 resin is first conveyed through a pipeline into the heating cylinder 3, and then... The heating cylinder 3 is equipped with a heating element. After heating, the PA66 resin gradually melts. Therefore, after starting the water pump 13, the PA66 resin is guided from the inside of the heating cylinder 3 to the inside of the purification chamber 1 through the L-shaped pipe 12 for filtration and purification. The PA66 resin is first guided to the inside of several guide pipes 5 through the distribution ring 4, and then guided to the inside of the nozzle 17 through several guide pipes 5. Finally, it is guided downward along the bottom surface of the nozzle 17. After starting the micro motor 6, the transmission rod 7 and the auxiliary rod 10 rotate simultaneously under the action of the belt 11. Multiple stirring rods 8 can stir the contents of the heating cylinder 3. The PA66 resin is stirred, and multiple L-shaped plates 15 and branch rods 16 rotate inside the purification chamber 1. The outer surfaces of the L-shaped plates 15 are in contact with the inner wall of the purification chamber 1. During the scraping process between the L-shaped plates 15 and the inner wall of the purification chamber 1, the PA66 resin adhering to the inner wall can be scraped off, avoiding waste of PA66 resin. Several branch rods 16 can stir the PA66 resin in the purification chamber 1. The combined stirring of the stirring rod 8 and the branch rods 16 helps to further improve the flowability of PA66 resin and improve the filtration efficiency of PA66 resin in subsequent devices. To improve the quality of purification, several nozzles 17 can increase the distribution range of PA66 resin, thereby increasing the contact area between the resin and the filter medium and improving the filtration efficiency. The auxiliary rod 10 rotates inside the support rod 9, which in turn drives the circular sleeve 14 fixedly fitted with it to rotate. Multiple L-shaped plates 15 and several branch rods 16 can then rotate synchronously. The branch rods 16 can perform circumferential motion inside the filter frame 18 and stir in a vertical state. The filter screen 19 can remove larger particles of impurities mixed in with the PA66 resin, thereby achieving the separation and purification of PA66 resin from impurities.
