According to the crushing and recycling equipment for the optical cable waste, when the resistance borne by a first-stage grinding cavity or a second-stage grinding cavity is increased, the cutters deflect, the angles of the sharp edge ends and the blunt edge ends relative to the movement direction of the light-guide fiber are changed, so that the cutting strength of light-guide fibers is changed; and the positions of the material raising faces and the material gathering faces relative to the material passing openings are changed, the flow guide direction of the light-guide fibers is changed, and then the grinding force of the first-stage grinding cavity and the second-stage grinding cavity is automatically adjusted according to the change of the resistance of the grinding cavities, so that the stacking and jamming are avoided, and the grinding efficiency is improved.

The invention relates to the technical field of sewage treatment, and discloses a kitchen sewage treatment device for solving the problems of incomplete separation and low convenience. The kitchen sewage treatment device comprises a shell, and the interior of the shell is movably connected with a screen frame. Vibration operation and oil-water separation operation are triggered through the gravityeffect of sewage, the linkage between structures is increased, and the device has high automation degree. The screen frame vibrates, separation of oil, water and impurities is promoted, the impurities are vibrated and transferred out of the screen frame, cleaning and collection of the impurities are achieved, screen holes are prevented from being blocked by excessive accumulation of the impurities, sewage discharge efficiency is reduced, hands are liberated, frequent manual cleaning and collecting operation is omitted, operation is convenient, and actual use requirements are better met. Condensed grease is automatically retained on the surface of a filter plate, water smoothly passes through the filter plate, the grease is thrown out of the filter plate under the centrifugal action generated by rotation of the filter plate and moves into an oil collecting tank to be collected in a centralized mode, grease is prevented from flowing into a sewer along with water to cause blockage, and the device has high practicability.

The invention relates to the technical field of optical cable recovery, in particular to equipment for crushing and recycling optical cable waste. It includes a shell, several grinding plates, a driving device and several grinding parts. The grinding part is rotatably arranged between the two upper and lower adjacent feed ports. Each grinding part includes two grinding parts located on both sides of the grinding plate. And the tool that can rotate synchronously has structures such as a grinding surface, a mounting surface, a sharp edge end, a first transition surface, a gathering surface, a blunt edge edge, and a lifting surface. In the present invention, when the resistance of the primary grinding cavity or the secondary grinding cavity increases, the tool deflects, and the angle between the sharp blade end and the blunt blade end relative to the moving direction of the optical fiber changes, so as to change the cutting force on the optical fiber and lift the material. The position of the surface and the aggregate surface relative to the material opening is changed to change the guiding direction of the optical fiber, so as to adjust the grinding force of the primary grinding chamber and the secondary grinding chamber according to the change of the resistance of the grinding chamber to avoid material stacking Jamming, improve grinding efficiency.
