| titleOfInvention | Production line device for recycling acetone during production of cefotaxime sodium |
| abstract | The utility model discloses a production line device for recycling acetone during the production of cefotaxime sodium. The production line device comprises an acetone mother solution storage tank, a rectifying tower, a condensing device, a mixed mother solution storage tank communicated with the inlet of the rectifying tower, two claw-type dry vacuum pumps and two efficient condensers, wherein the acetone mother solution storage tank is used for containing an acetone mother solution separated after the crystallization of the cefotaxime sodium, the condensing device is communicated with a gas-phase collection outlet in the top of the rectifying tower, the inlet of a first claw-type dry vacuum pump is communicated with the top of the acetone mother solution storage tank, and the outlet of the first claw-type dry vacuum pump is communicated with the outlet of a first efficient condenser; the inlet of a second claw-type dry vacuum pump is communicated with a drying device which is used for drying cefotaxime sodium crystals, and the outlet of the second claw-type dry vacuum pump is communicated with the inlet of a second efficient condenser; and the outlets of the first efficient condenser and the second efficient condenser are communicated with the mixed mother solution storage tank. By utilizing the production line device for recycling the acetone during the production of the cefotaxime sodium, the production cost is low, high-purity acetone can be obtained, and the high recovery rate is achieved. |
