A first motor 12 is fixedly mounted on the reaction vessel 11, and a stirring shaft is disposed inside the reaction vessel 11. The output shaft of the first motor 12 is fixedly connected to the stirring shaft. A feed inlet 13 is fixedly mounted on the reaction vessel 11. The raw materials required for synthesizing phosphorus-containing phenolic resin are added through the feed inlet 13. The first motor 12 is started to drive the stirring shaft to stir and process the raw materials. The reaction vessel 11 and the grinding cylinder... A feed pipe 10 is fixedly installed between the grinding cylinder 5 and the reactor 11. A valve is installed at the connection between the feed pipe 10 and the reactor 11. A bearing 9 is fixedly installed at one end of the grinding cylinder 5 near the feed pipe 10. The feed pipe 10 is fixedly connected to the inner ring of the bearing 9, and the grinding cylinder 5 is fixedly connected to the outer ring of the bearing 9. The purpose of the above is to start the second motor 4 and drive the grinding cylinder 5 to rotate, so as to grind the grinding stones in the grinding cylinder 5 on the mixture entering the grinding cylinder 5 from the reactor 11, without affecting the transmission of the feed pipe 10. A discharge port 7 is fixedly installed on the grinding cylinder 5. An electric push rod 6 is fixedly installed on the grinding cylinder 5. The output shaft of the electric push rod 6 is fixedly connected to a cover plate 8. A baffle groove matching the cover plate 8 is opened on the discharge port 7. When the electric push rod 6 is started, the electric push rod 6 pushes the cover plate 8 to move, so as to facilitate the closure of the cover plate 8 and the discharge port 7.

[0027] In one embodiment of this invention, a collection box 15 and a filter assembly 16 are provided inside the support 2. The filter assembly 16 is fixedly installed inside the support 2, and the collection box 15 is placed below the filter assembly 16. A cover 3 is rotatably installed on the support 2, which provides some protection for the collection box 15 and the filter assembly 16. The filter assembly 16 includes a guide plate 17, an elastic element 18, and a filter plate. A pair of guide plates 17 and elastic elements 18 are provided and fixedly connected to the support 2. One end of the elastic element 18 is fixedly connected to the guide plate 17, and the other end is fixedly connected to the filter plate. The aperture of the filter plate is adjustable. Specifically, the filter plate includes a first filter plate 23 and a second filter plate 24. Both the first filter plate 23 and the second filter plate 24 have filter holes. The elastic element 18 is fixedly connected to the first filter plate 23. The second filter plate 24 is slidably installed inside the first filter plate 23. A connecting rod 22 is fixedly installed on the side of the second filter plate 24, and a locking block 21 is fixedly installed at the end of the connecting rod 22. A through groove 19 is provided on the side of the filter plate 23, and several slots 20 are provided on the through groove 19. The slots 20 match the locking blocks 21. The connecting rod 22 is slidably disposed in the through groove 19. Pulling the locking blocks 21 until the locking blocks 21 disengage from the slots 20 and pulling the connecting rod 22 along the through groove 19 can drive the second filter plate 24 to slide within the first filter plate 23, thereby realizing the adjustment of the pore size of the first filter plate 23 and the second filter plate 24 stacked together. After the adjustment is completed, push the locking blocks 21 to the slots. With 20 locking mechanisms, the aperture can be restricted. After processing in the grinding cylinder 5, the discharge port 7 is adjusted to be directly above the filter assembly 16 by the second motor 4. Then, the electric push rod 6 is activated to drive the cover plate 8 to detach from the discharge port 7. The mixture in the grinding cylinder 5 falls into the filter assembly 16 through the discharge port 7. The first filter plate 23 and the second filter plate 24 vibrate under the elastic action of the elastic element 18, accelerating the filtration of the mixture. The filtered mixture falls into the collection box 15 for collection.

[0028] Working principle:

[0029] First, adjust the size of the filter plate pores as needed. Pull the locking block 21 until it disengages from the slot 20. Pull the connecting rod 22 along the through groove 19 to slide the second filter plate 24 within the first filter plate 23, thus adjusting the pore size of the stacked first filter plate 23 and second filter plate 24. After adjustment, push the locking block 21 until it engages with the slot 20 to limit the pore size. Then, add the phenols, catalyst, and phosphate ester required for synthesizing phosphorus-containing phenolic resin into the reactor 11 in proportion. Start the first motor 12 to drive the stirring shaft to stir the raw materials. The processed mixture is then conveyed through the feed pipe 1. The material enters the grinding cylinder 5, and then the second motor 4 is started to drive the grinding cylinder 5 to rotate, so that the grinding stones in the grinding cylinder 5 grind the mixture that enters from the reactor 11 into the grinding cylinder 5. After the processing in the grinding cylinder 5 is completed, the discharge port 7 is adjusted to be directly above the filter assembly 16 by the second motor 4. Then the electric push rod 6 is started to drive the cover plate 8 to separate from the discharge port 7. The mixture in the grinding cylinder 5 falls into the filter assembly 16 through the discharge port 7. The first filter plate 23 and the second filter plate 24 vibrate under the elastic action of the elastic element 18, which accelerates the filtration of the mixture. The filtered mixture falls into the collection box 15 for collection.
