[0024] Next, in combination with the specification drawings of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Refer to Figure 1 - Figure 3 One embodiment provided by the present utility model: A filtering device for polycarbonate production and processing includes a filter tank 1. A card slot 2 is provided on the outer wall of the filter tank 1. A filter cylinder 3 is slidably connected to the inner wall of the filter tank 1. An L-shaped plate 4 is fixedly connected to the outer wall of the filter cylinder 3. A first connection block 5 is fixedly connected to the outer wall of the L-shaped plate 4. A first fixing column 6 is fixedly connected to the inside of the first connection block 5. A card plate 7 is rotatably connected to the outer wall of the first fixing column 6. A spring 8 is fixedly connected to the outer wall of the card plate 7. One end of the spring 8 is fixedly connected to the outer wall of the L-shaped plate 4. The outer wall of the L-shaped plate 4 is slidably connected to the inner wall of the filter tank 1. The outer wall of the card plate 7 is slidably connected to the inner wall of the filter tank 1. The outer wall of the card plate 7 is slidably connected to the inner wall of the card slot 2. A feed inlet 12 is provided on the outer wall of the filter tank 1. A flip cover assembly is provided on the outer wall of the filter tank 1; The flip cover assembly includes a fixing block 9. The outer wall of the fixing block 9 is fixedly connected to the outer wall of the filter tank 1. A second fixing column 10 is fixedly connected to the inside of the fixing block 9. A sealing cover 11 is rotatably connected to the outer wall of the second fixing column 10;

[0026] Specifically, the feed port 12 is used to transport the polycarbonate material into the interior of the filter tank 1, and the filter cartridge 3 is used to filter the polycarbonate material. After the polycarbonate material enters the filter tank 1 through the feed port 12, most of the polycarbonate material directly enters the interior of the filter cartridge 3 without contacting the inner wall of the upper portion of the filter tank 1. This can prevent the polycarbonate material to be filtered from flowing out from the inner wall of the card slot 2 opened on the outer wall of the filter tank 1 and causing leakage. The first connecting block 5 fixedly connected to the outer wall of the L-shaped plate 4 is used to provide support for the first fixed column 6. When the card plate 7 is subjected to external force, it will rotate. On the outer wall of the first fixed column 6, the existence of the first fixed column 6 provides a rotation point for the card plate 7. One end of the spring 8 is fixedly connected to the outer wall of the L-shaped plate 4, and the other end is fixedly connected to the outer wall of the card plate 7, so as to reset and move the card plate 7. The sealing cover 11 is used to seal the filter tank 1 during the filtration process to prevent external impurities from entering the interior of the filter tank 1 and causing secondary pollution to the polycarbonate material. At the same time, the sealing cover 11 is also used to take the filter cartridge 3 out of the interior of the filter tank 1. The filter cartridge 3 can be taken out of the interior of the filter tank 1 only after the sealing cover 11 is opened.

[0027] Reference Figure 1 and Figure 2 The outer wall of the filter tank 1 is provided with a discharge port 13, the interior of the filter tank 1 is fixedly connected with a receiving plate 24, and the outer wall of the filter tank 1 is fixedly connected with a support plate 14;

[0028] Specifically, the receiving plate 24 is used to receive the polycarbonate material after filtering inside the filter cartridge 3 .

[0029] Reference Figure 1 and Figure 4 , the outer wall of the support plate 14 is provided with a motor 15, and the output end of the motor 15 is fixedly connected to a rotating shaft 16; the outer wall of the rotating shaft 16 is fixedly connected to a second connecting block 17, the outer wall of the second connecting block 17 is fixedly connected to a first rotating column 18, and the outer wall of the first rotating column 18 is rotatably connected to a connecting column 19; the outer wall of the support plate 14 is fixedly connected to a limiting block 22, and the inner part of the limiting block 22 is slidably connected to a reciprocating push rod 21; the inner part of the reciprocating push rod 21 is fixedly connected to a second rotating column 20, the inner wall of the connecting column 19 is rotatably connected to the outer wall of the second rotating column 20, and the outer wall of the reciprocating push rod 21 is slidably connected to the inside of the filter tank 1; one end of the reciprocating push rod 21 is fixedly connected to a material unloading push plate 23, and the lower end of the material unloading push plate 23 is slidably connected to the upper surface of the receiving plate 24;

[0030] Specifically, the support plate 14 is used to support and fix the motor 15, which can ensure the stability of the motor 15 during operation. The motor 15 is used to provide output power to the rotating shaft 16. When the motor 15 starts, it can drive the rotating shaft 16 to rotate. The connecting column 19 is used to convert the rotational motion of the second connecting block 17 into the reciprocating motion of the reciprocating push rod 21. The rotation of the second connecting block 17 causes the first rotating column 18 to rotate. Then, the first rotating column 18 drives the connecting column 19 to rotate on the outer wall of the first rotating column 18 and also on the outer wall of the second rotating column 20, and pulls the second rotating column 20 to move reciprocally. The reciprocating movement of the second rotating column 20 drives the reciprocating push rod 21 to slide reciprocally inside the filter tank 1 and inside the limiting block 22. The limiting block 22 is used to provide a limiting effect on the reciprocating push rod 21, which can ensure that the reciprocating push rod 21 always moves horizontally in a straight line. The blanking push plate 23 is used to gather and push out the polycarbonate material that has fallen above the material receiving plate 24. The discharge port 13 is used to discharge the polycarbonate material after filtration, and then the next process can be carried out.

[0031] Working principle: The polycarbonate material enters the filtration tank 1 from the feed inlet 12 and is filtered through the filter cartridge 3. After a long time of filtration, the filter cartridge 3 needs to be replaced or cleaned. First, open the sealing cover 11 and make the sealing cover 11 rotate on the outer wall of the second fixed column 10. When the sealing cover 11 is fully opened, press the clamping plate 7 to make the clamping plate 7 rotate on the outer wall of the first fixed column 6 and press the spring 8 to contract. When the clamping plate 7 completely slides out of the inner wall of the clamping groove 2 opened on the outer wall of the filtration tank 1, at this time, the filter cartridge 3 can be pulled upward and slide on the inner wall of the filtration tank 1. During the upward movement of the filter cartridge 3, it will drive the L-shaped plate 4 to move upward and then make the L-shaped plate 4 also slide on the inner wall of the filtration tank 1, so as to achieve the effect of quickly and conveniently disassembling the filter cartridge 3, and then it can be easily cleaned, replaced or maintained, which helps to keep the filtration equipment in good operating condition and ensure its normal filtration efficiency. After being filtered by the filter cartridge 3, the polycarbonate material falls above the receiving plate 24. At this time, start the motor 15 arranged on the outer wall of the support plate 14. The start of the motor 15 causes the rotating shaft 16 to rotate, and then the rotating shaft 16 drives the second connecting block 17 to rotate. The rotation of the second connecting block 17 causes the first rotating column 18 to rotate. Then, while the first rotating column 18 drives the connecting column 19 to rotate on the outer wall of the first rotating column 18, it also rotates on the outer wall of the second rotating column 20, and pulls the second rotating column 20 to move reciprocally. The reciprocating movement of the second rotating column 20 drives the reciprocating push rod 21 to slide reciprocally inside the filtration tank 1 and inside the limiting block 22, so as to drive the blanking push plate 23 to slide reciprocally on the receiving plate 24 to reciprocally gather and push the filtered polycarbonate material to the discharge port 13 and then discharge it through the discharge port 13 for the next operation, so as to achieve the effect of rapid blanking, and then it can speed up the filtration and blanking speed of the polycarbonate material, thereby shortening the production cycle and improving the production efficiency. This equipment can not only achieve the effect of quickly and conveniently disassembling the filter cartridge 3, and then it can be easily cleaned, replaced or maintained, which helps to keep the filtration equipment in good operating condition and ensure its normal filtration efficiency. In addition, it can also achieve the effect of rapid blanking, and then it can speed up the filtration and blanking speed of the polycarbonate material, thereby shortening the production cycle and improving the production efficiency.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
