Description

Technical Field

[0001] The utility model relates to the technical field of polyphenylene sulfide production, and particularly relates to a blockage prevention device for polyphenylene sulfide production. Background Technique

[0002] As is well known, polyphenylene sulfide is a new type of high-performance thermoplastic resin, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, excellent electrical properties, etc. A blockage prevention device for polyphenylene sulfide production is required during the production process.

[0003] The patent with the application number CN202022308639.X discloses a blockage prevention device for polyphenylene sulfide production, which relates to the field of polyphenylene sulfide production. The utility model includes a device main body, an operation table and an observation window are respectively installed on the outer surface of the device main body, a motor is installed on one side of the device main body, the output end of the motor is connected with a rotating shaft penetrating into the device main body, scraping plates are connected to the top and bottom of the rotating shaft through a plurality of telescopic spring rods, and turning grooves are formed on the outer surface of the scraping plates.

[0004] Although this device has the effect of making the materials receive heat more evenly when turning the materials, when the scraping plate of this device dumps the materials, the device does not discharge the materials in the turning groove in a way of uniform dispersion. Instead, the materials in the turning groove will flow downward together from the turning groove opening and be discharged. The discharged materials will gather together in large quantities and fall downward. Therefore, the heat receiving effect of the materials is not very good. Secondly, the scraping plate and the telescopic spring rods are fixedly arranged, and the telescopic spring rods and the rotating shaft are fixedly arranged. After the device is used for a period of time, when there is a lot of material attached to the surface of the telescopic spring rods and the scraping plate, it cannot be disassembled from the rotating shaft for separate cleaning. Therefore, the cleaning effect is not very good and there is still room for improvement. Content of the Utility Model

Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 - 5, an anti-blocking device for polyphenylene sulfide production of the present utility model, includes a device main body 1. An operation table 14 is arranged at the front part of the device main body 1 to control the operation of the anti-blocking device for polyphenylene sulfide production through the operation table 14. An observation window 15 is arranged at the front part of the device main body 1 to penetrate the internal situation of the anti-blocking device for polyphenylene sulfide production through the observation window 15. Several hydraulic cylinders 9 are installed at the lower part of the device main body 1. A material blocking net 10 is arranged at the upper part of the several hydraulic cylinders 9. A material blocking block 11 is arranged at the lower part of the material blocking net 10. When the hydraulic cylinder 9 is started, the hydraulic cylinder 9 extends, driving the material blocking net 10 and the material blocking block 11 to move upward, driving the polyphenylene sulfide material to move upward. A connecting rod is rotatably connected to the middle part of the device main body 1 through a rotating shaft. A motor 2 is installed at the right part of the connecting rod. When the motor 2 is started, the motor 2 rotates, driving the connecting rod to rotate. A support plate is arranged at the lower part of the motor 2. The left part of the support plate is connected to the right part of the device main body 1, and the support plate fixes the motor 2 on the device main body 1. A connecting plate 3 is arranged outside the connecting rod. Several threaded holes 4 are respectively arranged on both sides of the connecting plate 3 and are all threadedly connected with telescopic spring rods 5. One ends of the several telescopic spring rods 5 are all rotatably connected with scraping plates 6 and are installed on the connecting plate 3 through the threaded connection mode of the telescopic spring rods 5 and the threaded holes 4. During installation, the other ends of the telescopic spring rods 5 and the scraping plates 6 are rotatably arranged. Finally, after the scraping plates 6 are installed, collection grooves 7 are arranged inside the several scraping plates 6. Several discharge holes 8 are arranged on the several scraping plates 6. When the motor 2 rotates, it drives the scraping plates 6 to rotate and move to the lower part of the device main body 1, scraping the polyphenylene sulfide material above the material blocking net 10 onto the scraping plates 6, then entering the collection grooves 7, and then rotating along with the rotation of the connecting rod. The material in the installation groove is discharged to the outside through the several discharge holes 8 and uniformly drops for comprehensive heating. There is a gap between each of the several scraping plates 6 and the inner wall of the device main body 1 to prevent the scraping plates 6 from rubbing against the inner wall of the device main body 1 when rotating. Each of the several scraping plates 6 is made of metal material, and the metal material has good quality and long service life. A discharge pipe 12 is arranged in the middle of the device main body 1 for discharging polyphenylene sulfide material. The discharge pipe 12 is in a clamping connection with the material blocking block 11. The material blocking block 11 moves upward along with the material blocking net 10 and no longer blocks the discharge pipe 12, facilitating the discharge of polyphenylene sulfide material. A valve 13 is arranged at the lower part of the discharge pipe 12. When the valve 13 is opened, the material in the discharge pipe 12 can be discharged.

[0025] In summary, when the anti-blocking device for polyphenylene sulfide production is in use, the polyphenylene sulfide material is added into the device. The hydraulic cylinder 9 is started, and the hydraulic cylinder 9 extends, driving the baffle net 10 and the baffle block 11 to move upward, driving the polyphenylene sulfide material to move upward. The motor 2 is started, the motor 2 rotates, driving the connecting rod to rotate, and then driving the scraping plate 6 to rotate. After contacting the material on the baffle net 10, the hydraulic cylinder 9 is closed. At the same time, the scraping plate 6 scrapes the material into the collection tank 7. As the scraping plate 6 rotates upward away from the lower material, the material in the collection tank 7 is discharged to the outside through several discharge holes 8 and uniformly falls downward for full heating. After the scraping plate 6 moves to the directly above, another scraping plate 6 continues to scrape the material, and so on, cycling and cooperating to turn the material.
