Fig. 1 is the structural representation of the present invention's a kind of Chinese medicine scraper plate enrichment facility and liquid density online detection method one preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of Chinese medicine scraper plate enrichment facility, comprise: scraper plate decompression concentrator 1, steam valve 3, vacuum valve 4 and densitometer 6, described scraper plate decompression concentrator 1 is connected with steam pipeline 31, described steam valve 3 is arranged on steam pipeline 31, opens steam valve 3, and in phase scraper plate decompression concentrator 1, delivering vapor heats, described scraper plate decompression concentrator 1 is provided with a paddle 2, carry out the stirring of liquid, driven by motor, regulable control is more convenient.
Described scraper plate decompression concentrator 1 is connected with the first condensation liquid trap 8, be provided with condensation pipe 9 between described scraper plate decompression concentrator 1 with the first condensation liquid trap 8 to be connected, described condensation pipe 9 side is connected with vacuum lead 41, described vacuum valve 4 is arranged on vacuum lead 41, described densitometer 6 to be arranged on bottom scraper plate decompression concentrator 1 and to extend to inside it, carries out the measurement of scraper plate decompression concentrator 1 inner liquid medicine density.
Described condensation pipe 9 is in series with the second condensation liquid trap 7, carry out just imitating condensation, condensed water flows into scraper plate decompression concentrator 1.Described first condensation liquid trap 8 is positioned at the below of scraper plate decompression concentrator 1 side, and the condensed water in the first condensation liquid trap 8 concentrates discharge, and described second condensation liquid trap 7 is positioned at the top of scraper plate decompression concentrator 1 side, is convenient to condensate return.
