[0002] Benzophenone, also known as benzophenone or dibenzophenone, is an organic compound that is mainly used as a fragrance fixative, ultraviolet absorber, styrene polymerization inhibitor, light curing agent, gas chromatography stationary liquid, and can also be used in organic synthesis. During the production process of benzophenone, feeding equipment is required to transport its raw materials. The current automatic feeding device for preparing benzophenone generally uses a feeding pump and a solenoid valve to quantitatively feed the raw materials in the material box through a feeding pipe into the interior of a reactor or a reaction box for processing. After the feeding pipe has been transporting the raw materials for a long time, some of the raw materials are likely to remain on the inner wall of the feeding pipe, which is likely to cause blockage during subsequent feeding, affecting the preparation of benzophenone.

Under continuous rotation, the extrusion plate 13 can be moved away from the surface of the support rod 2. Under the action of the torsion spring 14 and the like, the extrusion plate 13 can be reset so that the rubber pad on one side of the extrusion plate 13 collides with the feed pipe 7, and the raw materials remaining on the inner wall of the feed pipe 7 can be knocked off to avoid excessive residual raw materials clogging the feed pipe 7 and affecting the preparation of benzophenone.

This is convenient for the extrusion plate 13 to rotate, so that the extrusion plate 13 can first move to the surface of the support rod 2 and then move to the surface of the feed pipe 7.

[0026] Furthermore, a rubber pad is installed on the surface of the extrusion plate 13 to provide a buffer when the extrusion plate 13 collides with the feed pipe 7 .

[0027] Furthermore, a torsion spring 14 and a fixing rod 15 are installed inside the rotating tube 12. The torsion spring 14 and the fixing rod 15 are used to facilitate the rotating tube 12 to drive the extrusion plate 13 to reset.
