[0002] In the production of polycarbonate, a temperature-controlled mixing process is often required to ensure uniform mixing of its components and achieve ideal product performance. While existing polycarbonate temperature-controlled mixing devices can achieve basic mixing and temperature control functions, they have shortcomings in the discharge process. During the discharge process after mixing, some undissolved impurities, agglomerated particles, or debris from equipment wear may mix into the discharged material. These impurities can affect the quality of subsequent polycarbonate products, causing surface defects and uneven internal structure during molding and processing. Conventional filtration methods are often performed in a separate subsequent process, increasing equipment costs and process complexity. Therefore, it is necessary to improve the discharge port structure of the polycarbonate temperature-controlled mixing device to enable convenient and effective filtration. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a temperature-controlled stirring and mixing device for polycarbonate, including a stirring tank 1 and a tank cover 3. A shell 2 is fixedly connected to the outer wall of the stirring tank 1. A heating wire 24 is provided between the stirring tank 1 and the shell 2. A temperature sensor 23 is fixedly connected to the bottom of the tank cover 3. An operation panel 25 and a controller 26 are fixedly connected to the surface of the shell 2. A discharge pipe 4 is fixedly connected to the bottom of the stirring tank 1. A valve 5 and a filter box 6 are provided on the discharge pipe 4. A slag discharge pipe 15 is fixedly connected to the bottom of the filter box 6. A sealing cap 16 is provided at the bottom of the slag discharge pipe 15. A square groove 8 is opened at the top of the filter box 6, and a slot 9 is opened at the bottom of the square groove 8. A filter screen plate 11 is inserted inside the slot 9. A connecting plate 12 is fixedly connected to the top of the filter screen plate 11. The connecting plate 12 is fixed inside the square groove 8 by a locking assembly 7. A sealing gasket 10 is provided between the connecting plate 12 and the locking assembly 7, which includes a fixing block 701, a screw 702, a knob 703 and a locking block 704. The screw 702 is threadedly connected to the inside of the fixing block 701, the knob 703 is fixedly connected to the top of the screw 702, and the locking block 704 is rotatably connected to the screw 702 and is locked on the top of the connecting plate 12. There are two locking assemblies 7, which are symmetrically distributed on both sides of the middle of the surface of the connecting plate 12. A limiting groove 13 is opened on the surface of the connecting plate 12. A limiting rod 14 is fixedly connected to the bottom of the locking block 704 at the position corresponding to the limiting groove 13. The limiting rod 14 is inserted into the limiting groove 13. A motor 17 is fixedly connected to the top of the lid 3. The output end of the motor 17 passes through the lid 3 and is fixedly connected to a rotating shaft 18. A stirring rod 19 is fixedly connected to the surface of the rotating shaft 18.
[0023] In this embodiment, by setting a filter box 6 on the discharge pipe 4 and inserting a filter screen 11 inside the filter box 6, incompletely dissolved impurities, agglomerated particles, and debris generated by equipment wear can be filtered out during discharge, preventing these impurities from affecting the quality of subsequent products and reducing problems such as surface defects and uneven internal structure. Compared with the conventional method of setting a separate filtration process, this reduces equipment costs and process complexity. At the same time, by opening the sealing cover 16 on the slag discharge pipe 15 at the bottom of the filter box 7, it is also convenient to clean the impurities inside the filter box 6. By rotating the knob 703 of the locking assembly 7, the screw 702 is driven to lock. The internal rotation of the fixed block 701 causes the locking block 704 to lock onto the top of the connecting plate 12, thus fixing the filter screen 11. This structure is simple and easy to operate, and it also facilitates disassembly when the filter screen 11 needs to be replaced or cleaned. The two symmetrically distributed locking components 7 make the fixing of the filter screen 11 more stable and the force evenly distributed, preventing the filter screen 11 from loosening due to uneven force during the filtration process. The limiting rod 14 at the bottom of the locking block 704 is inserted into the limiting groove 13 on the connecting plate 12 to prevent unnecessary shaking or misalignment of the locking block 704 during use, ensuring reliable fixing of the filter screen 11.
[0024] Example 2: As Figure 4 As shown, a support plate 22 is fixedly connected to the edge of the bucket lid 3, an electric push rod 27 is fixedly connected to the surface of the outer shell 2, the output end of the electric push rod 27 is fixedly connected to the support plate 22, a connecting rod 20 is fixedly connected to the surface of the rotating shaft 18, and a scraper 21 is fixedly connected to the end of the connecting rod 20 away from the rotating shaft 18.
[0025] In this embodiment, the opening and closing of the lid 3 can be easily achieved by the electric push rod 27, facilitating the addition of materials to the mixing tank 1 and the inspection and maintenance of the equipment. This improves the convenience and flexibility of the device operation, eliminating the need for manual and laborious opening or closing of the lid 3, thus enhancing the level of automation. While the rotating shaft 18 drives the stirring rod 19 to mix the materials, the scraper 21 at one end of the connecting rod 20 rotates accordingly. The scraper 21 can scrape off the materials adhering to the inner wall of the mixing tank 1, preventing the materials from adhering and forming scale over a long period of time, which would affect heat transfer and the full mixing of the materials. This ensures that all materials in the mixing tank 1 can participate in the mixing process, further improving the uniformity of the material mixing. It also helps to maintain a good cleanliness inside the mixing tank 1, facilitating subsequent cleaning and maintenance.
[0026] The working principle of this embodiment is as follows: In use, firstly, when using this polycarbonate temperature-controlled stirring and mixing device, the electric push rod 27 pushes the support plate 22 to open the lid 3, allowing the polycarbonate raw materials and related additives to be added into the mixing tank 1. Then, the electric push rod 27 closes the lid 3, ensuring the mixing tank 1 is sealed. Next, the operator can set the required mixing parameters, such as temperature, stirring time, and stirring speed, through the operation panel 25. After receiving these parameters, the controller 26 coordinates the operation of each part. When heating of the material is required, the controller 26, based on the real-time temperature signal of the material inside the tank fed back by the temperature sensor 23, controls the heating wire 24 to start working, heating the material in the mixing tank 1 to raise the material temperature to a suitable set range, ensuring the material is mixed under appropriate temperature conditions. When the material temperature reaches or exceeds the set value, the controller 26 controls the heating wire 24 to stop heating to prevent excessively high temperatures from affecting the material properties. Subsequently, the motor 17 starts, and the electric... The output end of machine 17 drives the rotating shaft 18 to rotate, and the stirring rod 19 fixed on the rotating shaft 18 rotates accordingly, fully stirring the material in the mixing tank 1 to ensure uniform mixing of all components. During this process, the connecting rod 20 on the rotating shaft 18 drives the scraper 21 to rotate synchronously. The scraper 21 scrapes off the material adhering to the inner wall of the mixing tank 1, ensuring that all materials participate in the mixing process and improving the mixing effect. After the material is mixed, the valve 5 on the discharge pipe 4 is opened, and the material flows into the discharge pipe 4 under gravity, and then enters the filter box 6. When the material flows through the filter screen 11, incompletely dissolved impurities, agglomerated particles, and debris generated by equipment wear are intercepted by the filter screen 11. The pure polycarbonate material after filtration is discharged from the port of the discharge pipe 4 and enters the subsequent production stage. After filtration for a period of time, if it is necessary to clean the filtered waste residue, the sealing cap 16 at the bottom of the slag discharge pipe 15 can be unscrewed to discharge the waste residue. If the filter screen 11 is clogged or needs to be replaced or cleaned, first rotate the knob 703 and screw 702. Rotate and drive the locking block 704 to disengage from the top of the connecting plate 12. Then, pull the filter screen 11 out of the square groove 8 for cleaning or replacement. After that, fix the new or cleaned filter screen 11 with the locking assembly 7 and continue the subsequent discharge filtration work. The whole process achieves temperature control, stirring and mixing of polycarbonate and effective filtration during discharge through the coordinated cooperation of various components, ensuring product quality and simplifying the process flow.
