Online measurement device for crystal size and shape in high-solid-content crystallization process

An online measurement device for crystal size and shape in a high-solid-content crystallization process, comprising:

• a solution amplifier, a measurement device, a peristaltic pump, a crystallization kettle, a dilution device, and a solution storage tank,
• wherein a crystal-containing solution is arranged in the crystallization kettle;
• wherein an inner wall of the solution amplifier is smooth, a first end of the solution amplifier is an amplification end, and a second end of the solution amplifier is a contraction end;
• wherein identical through holes are formed in middle parts of both the first end and the second end of the solution amplifier, and the solution amplifier is communicated with a pipeline by the identical through holes;
• wherein the contraction end of the solution amplifier is communicated with a first end of the solution storage tank and a first end of the crystallization kettle;
• wherein the amplification end of the solution amplifier is communicated with the dilution device and the peristaltic pump;
• wherein the peristaltic pump is communicated with a second end of the crystallization kettle;
• wherein the solution amplifier, the peristaltic pump and the crystallization kettle form a complete passage through a pipeline;
• wherein a measurement instrument of the measurement device is arranged at an outer side of the solution amplifier and focuses on a solution in the amplification end of the solution amplifier;
• and wherein at least one stop valve is mounted on each branch of the pipeline.
