The utility model relates to the technical field of biodiesel production, in particular to a catalyst separation and recovery device for converting waste oil and fat into biodiesel, which comprises a separation tank. A feed pipe is fixedly connected to the rear position at the upper end of the separation tank, a waste discharge pipe is fixedly connected to the middle position at the lower end of the separation tank, two observation windows are fixedly connected to the front surface of the separation tank, and two adjusting components are arranged at the front position at the upper end of the separation tank. The adjusting components include a positioning sleeve, a connecting seat, a threaded sleeve, a first bevel gear, a second bevel gear, an electric motor, a threaded pipe, a connecting block, a positioning block, a discharge pipe, a first suction pipe, a second suction pipe, a positioning rod and a limiting block; the threaded pipe is driven to lift through the adjusting components, so as to adjust the heights of the first suction pipe and the second suction pipe, so that the floating oil and esterified glycerol can be accurately sucked, the separation quality of the esterified glycerol is effectively improved, the purity of the catalyst recovery is further improved, and the waste of the esterified glycerol is avoided.

This invention discloses an impact-resistant polyethersulfone composite material and its preparation method. A modified polymer and a modified filler are melt-blended, and a pretreated film is prepared using a blown film process. The pretreated film and a modified nonwoven fabric are then laminated and hot-pressed to obtain the impact-resistant polyethersulfone composite material. The modified polyethersulfone is formed by the stepwise polymerization of 4,4'-difluoro-diphenyl sulfone and a dihydroxy monomer, and then hindered amine structures are grafted onto the molecular side to obtain the modified polymer. The hindered amine structures can capture free radicals, improving the material's anti-aging properties, while the disulfide bond structure can absorb energy when the material is impacted, enhancing its impact resistance. A modified filler is prepared by coating a composite filler formed from TiO2 and CeO2 with silica, which can efficiently absorb and convert ultraviolet light, improving the material's anti-aging properties. Simultaneously, the interlayer nonwoven fabric structure effectively prevents cracks from directly penetrating to adjacent layers, enhancing the material's impact resistance.
