    Abstract: The present invention provides a high-strength and high-plasticity titanium matrix composite and a preparation method thereof. The preparation method includes: preparing high-oxygen hydride-dehydride titanium powder using a high-temperature rotary ball grinding treatment process, in which the prepared hydride-dehydride titanium powder has a particle size of 10-40 μm, and has an oxygen content of 0.8-1.5 wt. %; preparing high-purity ultra-fine oxygen adsorbent powder using a wet grinding method of high-energy vibration ball grinding treatment process; in which a purity of the oxygen adsorbent powder is ≥99.9%, and a particle size of the oxygen adsorbent powder is ≤8 μm; mixing the high-oxygen hydride-dehydride titanium powder with the oxygen adsorbent powder in a protective atmosphere, and then press-forming the powder obtained after mixing to obtain a raw material blank; and performing atmosphere protective sintering treatment on the raw material blank to obtain a titanium matrix composite. The method prepares a titanium matrix composite reinforced by in-situ self-generating multi-scale Ca—Ti—O, TiC, TiB particles. The microstructure and grains are effectively refined, and the strength and plasticity of the material are significantly improved.

    Abstract: Solid-liquid separation equipment includes a pulverizing and drying device. The pulverizing and drying device includes a pulverizing device and a drying device connected with one another. The pulverizing device has a pulverizing shell, an inlet, a main shaft and impellers, and the main shaft and the impellers are arranged in the pulverizing shell. The impellers are configured to rotate around the main shaft. The inlet forms a sidewall of the pulverizing shell and is intersected with the main shaft or an extension line of the main shaft. A gap is defined between an outer peripheral end of the impeller and the wall of the pulverizing shell. The sludge is efficiently and deeply dried in a condition with no phase change. The sludge is graded, pulverized and dried. During the pulverizing and drying process, the water is liquefied and centrifugally separated, and the water is not completely phase-transformed and removed.
