[0002] Resin usually refers to an organic polymer that has a softening or melting range when heated, has a tendency to flow under the action of external force when softened, and is solid, semi-solid or sometimes liquid at normal temperature. In a broad sense, any high molecular compound that can be used as a processing raw material for plastic products is called resin. The uses of resin now include fibers, various containers, packaging materials, films, films, engineering plastics and other fields.

[0003] In the patent of a polycondensation kettle feeding and filtering device with the authorization announcement number of CN208229868U, the utility model can effectively filter the polyester slurry entering the polycondensation kettle, avoid impurities in the polyester slurry from entering the polycondensation kettle, and ensure the product quality of polyester particles; when the pressure value of the feed pipe shows that the filter on this pipeline is blocked, only need to close the control valve on this feed pipe, and then the filter on this pipeline can be cleaned. Since two filtering channels are provided, the feeding of the polycondensation kettle can be ensured to be unobstructed at any time, and equipment shutdown caused by filter blockage can be avoided.

[0004] However, the above patent still has the following problems: when the filter screen of the above patent is in use, impurities will accumulate on the surface of the filter screen until the filter screen is blocked. The above patent cannot clean the impurities on the surface of the filter screen while adding materials. When impurities accumulate on the surface of the filter screen, the liquid drainage effect of the filter screen will decrease, thereby reducing the feeding efficiency. Therefore, a polycondensation kettle feeding and filtering device for resin production is proposed for the above problems. Content of the Utility Model

[0024] Embodiment

[0025] Such as Figures 1-4As shown in the figure, a polycondensation kettle feeding and filtering device for resin production includes a polycondensation kettle main body 1 and a feeding pipe 2. The inlet end of the polycondensation kettle main body 1 is fixedly connected to the feeding pipe 2. A feeding frame 3 is fixedly connected to the outer side of the feeding pipe 2. The outer side of the other end of the feeding pipe 2 is fixedly connected to a shaft seal 15. The outer side of the shaft seal 15 is fixedly connected to a filtering cylinder 8, and the filtering cylinder 8 is rotationally connected to the feeding frame 3. Through the shaft seal 15, the sealing performance between the feeding pipe 2 and the filtering cylinder 8 can be ensured, preventing impurities from entering the inner side of the feeding pipe 2 through the gap between the feeding pipe 2 and the filtering cylinder 8. At the same time, after the raw materials are filtered, they will pass through the filtering cylinder 8 and enter the inner side of the feeding pipe 2. Meanwhile, under the action of the shaft seal 15, the filtering cylinder 8 can rotate normally. One end of the feeding frame 3 is fixedly connected to a first motor 5, and the end of the main shaft of the first motor 5 is fixedly connected to the filtering cylinder 8. Through the first motor 5, the filtering cylinder 8 can be driven to rotate inside the feeding frame 3. One end of the polycondensation kettle main body 1 is fixedly connected to a controller 16. A fixing plate 7 is fixedly connected to the inner side of the feeding frame 3. A filtering frame 9 is fixedly connected to the bottom end of the fixing plate 7, and the filtering frame 9 is slidably connected to the filtering cylinder 8. When raw materials need to be added to the inner side of the polycondensation kettle main body 1, the raw materials are poured on the upper side of the filtering cylinder 8. The filtering cylinder 8 filters the impurities in the raw materials. During the filtering process, as the filtering cylinder 8 rotates, the impurities attached to the surface of the filtering cylinder 8 will enter the inner side of the filtering frame 9 and be collected centrally through the filtering frame 9, so as to ensure that during feeding, the influence of impurities on the normal operation of the filtering cylinder 8 is reduced, and the influence of impurities on the liquid drainage of the filtering cylinder 8 is reduced, thereby improving the feeding efficiency.

[0026] As a further improvement of the present invention, as Figure 1 and Figure 2 shown, a second motor 6 is fixedly connected to one end of the feeding frame 3. The end of the main shaft of the second motor 6 is fixedly connected to a roller 12, and the roller 12 is rotationally connected to the filtering frame 9. A brush 13 is fixedly connected to the outer side of the roller 12, and the brush 13 is in contact with the surface of the filtering cylinder 8. During the relative rotation of the filtering cylinder 8 and the filtering frame 9, the second motor 6 will drive the brush 13 to rotate counterclockwise through the roller 12, so that impurities can smoothly enter the inner side of the filtering frame 9 under the auxiliary action of the brush 13, preventing impurities from accumulating at the entrance of the filtering frame 9.

[0027] As a further improvement of the present invention, as Figure 2 shown, a cover plate 10 is snap-fitted to the inner side of the top end of the filtering frame 9. One end of the cover plate 10 is fixedly connected to a handle 11. When no raw materials are added to the inner side of the polycondensation kettle main body 1, the cover plate 10 can be removed from one side of the filtering frame 9 through the handle 11, so as to facilitate the staff to centrally process the impurities inside the filtering frame 9.

[0028] As a further improvement of the present invention, as Figure 2As shown, a connection cover 14 is placed on the top of the feeding frame 3. When the feeding frame 3 is not feeding, the top of the feeding frame 3 is covered by the connection cover 14 to prevent dust from entering the inside of the feeding frame 3.

[0029] As a further improvement of the present utility model, as Figure 1 shown, a support plate 4 is fixedly connected to the bottom end of the feeding frame 3, and the support plate 4 is fixedly connected to the polycondensation kettle main body 1. The stability of the feeding frame 3 can be improved through the support plate 4.

[0030] Working process: When raw materials need to be added to the inside of the polycondensation kettle main body 1, the raw materials are poured on the upper side of the filter cylinder 8. The filter cylinder 8 filters the impurities in the raw materials. During the filtering process, as the filter cylinder 8 rotates, the impurities attached to the surface of the filter cylinder 8 will enter the inside of the filter frame 9 and are collected centrally through the filter frame 9, so as to ensure that during feeding, the influence of impurities on the normal operation of the filter cylinder 8 is reduced, and the influence of impurities on the liquid drainage of the filter cylinder 8 is reduced, thereby improving the feeding efficiency. During the relative rotation of the filter cylinder 8 and the filter frame 9, the second motor 6 will drive the brush 13 to rotate counterclockwise through the roller 12, so that the impurities can smoothly enter the inside of the filter frame 9 under the auxiliary action of the brush 13, preventing the impurities from accumulating at the entrance of the filter frame 9. When the inside of the polycondensation kettle main body 1 is not feeding, the cover plate 10 can be removed from one side of the filter frame 9 through the handle 11, which is convenient for the staff to centrally process the impurities inside the filter frame 9.
