  • Publication number: 20230211258
    Abstract: The disclosure provides a device and method for extracting a clean liquid from a slurry reactor in an environment-friendly and energy-saving manner. The method mainly includes the following steps: S1. siphoning slurry in the slurry reactor into a material collecting pipe, and then spraying the slurry into a settling tank, so that solid particles settle in the settling tank and return to the slurry reactor through a discharging pipe; S2. making supernatant in the settling tank flow upward along a settling pipe, and then flow downward at a pipe intersection into a clear liquid pipe and flow into a clear liquid transition tank; S3. discharging liquid from the clear liquid transition tank in an overflow manner to keep the constant liquid level and a pressure required for siphoning; and S4.

  • Patent number: 8894966
    Abstract: A micro-mixer and use thereof for synthesis of barium sulfate particles is disclosed. The micro-mixer includes feeding tubes, reservoirs, a mixing channel, a buffer reservoir and a sampling tube. The mixing channel is made of hydrophobic materials and processed into a spiral structure, in which baffles are set in interval arrangement at both sides of the channel wall. The types of the baffles include leaning-forward baffles, vertical baffles and leaning-backward baffles. Setting the baffles helps produce local secondary flow in the mixer, which enhances fluids mixing process. The micro-mixer is suitable to rapid reactions or precipitation processes, whose reaction time is much less than mixing time, and has broad application prospects in many fields involving mixing reaction such as pharmaceutical and chemistry industry.

  • Patent number: 8642765
    Abstract: A novel class of azaindole-indole coupled derivatives, their preparation methods, pharmaceutical compositions containing the same and the uses thereof. The common structural feature of these derivatives is that they are coupled by azaindole and indole bi-molecule at different positions, forming extended pi-conjugated systems. Such derivatives inhibited cell growth and proliferation by various mechanisms. The present compounds have improved solubility, increased bioavailability, and thus have enhanced drug actions, and reduced medical dosages and undesired responses.
