The front and rear sides of the filter bin 1 are fixed with side panels by bolts, and the surface of the side panel is provided with fasteners 3 that threadably match the threaded holes of the fixing seat 704.

[0026] In a specific embodiment of the present invention, filter holes for filtering materials are provided on the surface of the filter plate 701, and both ends of the filter plate 701 are assembled with the enclosure strip 702 by welding. The enclosure strip 702 is used to prevent materials from falling from the gap between the filter plate 701 and the filter bin 1. Bearings are inlaid at both ends of the main shaft 703, and the circular holes at the ends of the enclosure strip 702 match the outer rings of the bearings, thereby achieving the effect of the enclosure strip 702 ends rotating around the main shaft 703. The gap between the filter plate 701 and the surface of the main shaft 703 is set to 2 mm to avoid friction between the filter plate 701 and the main shaft 703.

[0027] The filter bin 1 is detachably mounted with side panels at the front and rear by bolts, so that the side panels can be removed for maintenance of the components inside the filter bin 1. The fixing seats 704 on both sides of the bottom of the U-shaped seat 705 are aligned with the fasteners 3 on the surface of the side panels, so that the U-shaped seat 705 can be fastened to the filter bin 1 as a whole. The main shaft 703 is connected to the push rod end of the lifting push rod motor 706 through the connecting seat 707. One end of the filter plate 701 is always overlapped with the surface of the through groove 8. The lifting push rod motor 706 is controlled by the controller 4. The electric energy of the lifting push rod motor 706 is connected to the power supply through the power cord. The collecting trough 6 is used to collect materials that cannot pass through the filter plate 701, and the collecting trough 5 is used to collect materials that pass through the filter plate 701 for classified collection.

[0028] In the preferred technical solution, an arc groove is provided on the top surface of the connecting seat 707, and the shape of the arc groove matches the shape of the main shaft 703.

[0031] In the preferred technical solution, both ends of the main shaft 703 are provided with annular grooves, and clamps for preventing the enclosure strip 702 from falling off are clamped inside the annular grooves.

[0032] Working principle: When the filter mechanism 7 needs to filter the material, the push rod of the lifting push rod motor 706 is controlled to retract, so that the two filter holes 701 are distributed in a V shape (such as Figure 3As shown), the material to be filtered for the production of styrene polymerization inhibitor enters from the feed hopper 2, and the material falls on the surface of the filter hole plate 701. The material that cannot pass through the filter hole will accumulate on the surface of the filter hole plate 701, and the material that passes through the filter hole will fall into the collecting tank 5 for collection. During the process, the push rod of the lifting push rod motor 706 can be slightly extended and retracted to achieve the vibration of the two filter holes 701, which can improve the screening efficiency. When the filter hole plate 701 needs to be cleaned, the material input is stopped, and the push rod of the lifting push rod motor 706 is controlled to extend, so that the two filter holes 701 are distributed in an inverted V shape, and the filter hole plate 701 is cleared by a tool through the through slot 8.
