[0024] The cylinder body 301 is used as a driving component of the filter mechanism 3. By providing a power source, the push plate 304 can move up and down to push the impurities between the filter cylinder 306 and the filter sheet 307 to the slag discharge mechanism 4. The function of the sealing sleeve 302 is to ensure the sealing inside the filter mechanism 3 to prevent the polyurethane resin liquid from leaking. The push plate 304 is driven by the cylinder body 301 to move up and down to push the impurities to the slag discharge mechanism 4. The filter sheet 307 cooperates with the filter cylinder 306 to form a filtering channel to capture impurities in the polyurethane resin liquid, which improves the filtering effect and ensures the quality of the filtered resin liquid. The infusion tube 309 is used to discharge the filtered polyurethane resin liquid to the external storage bin, which ensures that the filtered resin liquid can be processed in time and ensures the smooth progress of the production process. The injection tube 310 is used to inject the polyurethane resin liquid into the filter tank 2 to start the filtering process, which ensures that the filtering device can operate normally and ensures the filtering effect.

The discharge pipe 404 is used to discharge the impurities in the slag bin 403, which helps to clean the slag bin 403 in time and ensure the smooth progress of the production process.

[0027] The working principle of the utility model is as follows: the filter device for polyurethane resin is additionally provided with a filter mechanism 3 and a slag discharge mechanism 4. Before using the filter device for polyurethane resin, it is necessary to pre-connect the cylinder body 301 with electricity and connect it to the control terminal, connect the liquid infusion tube 309 with the external storage bin, connect the liquid injection tube 310 with the polyurethane resin liquid injection end, and when using the filter device for polyurethane resin, the polyurethane resin liquid is injected into the filter tank body 2 through the polyurethane resin liquid injection end, so that the polyurethane resin liquid is filled into the filter tank body 2. The filter tank 2 is filtered through the filter cartridge 306 and the filter sheet 307, and the impurities will be blocked on the left side of the filter sheet 307. The filtered polyurethane resin liquid will be discharged to the outside storage bin through the infusion tube 309. After filtering a large amount of polyurethane resin liquid, a large amount of impurities will accumulate in the filter tank 2. At the same time, the filter mechanism 3 is activated, and the cylinder body 301 is started to push the connecting plate 303 and the pushing plate 304 downward. The protrusion 305 and the filter tank 308 are in a limit relationship. When the pushing plate 304 and the protrusion When the filter element 305 moves downward, the liquid and the impurities in the liquid are pushed downward, and the liquid is discharged from the infusion tube 309, while the impurities in the liquid are accumulated in the debris bin 403. After a large amount of impurities have accumulated in the debris bin 403, the slag discharge mechanism 4 is activated, and the cover body 405 and the handle 406 are rotated to remove the impurities. If it is necessary to clean the filter cartridge 306 and the filter sheet 307, it is only necessary to rotate and remove the threaded sleeve 402 and the debris bin 403, and the filter cartridge 306 and the filter sheet 307 can be cleaned, which is convenient for later use. In summary, the filter mechanism 3 and the slag discharge mechanism 4 complement each other. The filter mechanism 3 is used to filter the impurities in the polyurethane resin liquid to achieve the effect of cleaning the polyurethane resin liquid. The slag discharge mechanism 4 is used to receive the impurities discharged from the filter mechanism 3 and facilitate the discharge of impurities and particles. In addition, the filter mechanism 3 can not only perform filtering operations, but also introduce the filtered impurities into the slag discharge mechanism 4 to achieve a self-cleaning effect, and there is no need to stop the filtering operation of the device during the cleaning process, which is very time-saving and labor-saving.
