Raw material drying device for 7-chloro-6-fluoro-1-cyclopropyl-1,4-dihydro-4-oxo-3-quinoline carboxylic acid synthesis

Abstract

The invention discloses a raw material drying device for 7-chloro-6-fluoro-1-cyclopropyl-1,4-dihydro-4-oxo-3-quinoline carboxylic acid synthesis. A drying box is included, and a fixed plate is weldedto the inner wall of one side of the drying box; the side wall of one side of the fixed plate is provided with a groove; the side wall of one side of the groove is connected with a slider in a slidingmanner; a spring connected with the side wall of the top end of the groove is installed at the top end of the slider; a filtering net is hinged to the side wall of one side of the slider; the other end of the filtering net is hinged to the inner wall of the drying box; a triangular plate is welded to the bottom end of the slider; a driving motor connected with the side wall of the groove is installed below the triangular plate; the output end of the driving motor is connected with a rotating shaft; a rotating disk is welded to the end, away from the driving motor, of the rotating shaft; and aconical plate is welded to the side wall of the rotating disk in the axis direction array direction of the rotating disk. Due to the raw material drying device for 7-chloro-6-fluoro-1-cyclopropyl-1,4-dihydro-4-oxo-3-quinoline carboxylic acid synthesis, drying treatment can be fast performed on raw materials for 7-chloro-6-fluoro-1-cyclopropyl-1,4-dihydro-4-oxo-3-quinoline carboxylic acid synthesis, drying can be performed on the two sides of the raw materials at the same time, the raw materials can be shaken in drying, the raw materials are heated uniformly, and the drying effect and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of cyclopropanecarboxylic acid, in particular to a raw material drying device for cyclopropanecarboxylic acid synthesis. Background technique [0002] Cyclopropanecarboxylic acid is a chemical with the molecular formula C13H9ClFNO3. It is a yellowish or whiteish powder, which easily turns yellow when exposed to light or humid air. It is generally used as an intermediate of the new quinoline antibacterial drug ciprofloxacin. [0003] Before the traditional cyclopropanecarboxylic acid is synthesized, the synthesized raw materials need to be dried. During the drying process, the raw materials are easily piled together, resulting in poor drying effect of the raw materials at the bottom. Raw material drying device for cyclopropanecarboxylic acid synthesis. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the shortcoming existing in the prior art, and proposes a kind of raw m...

Problems solved by technology

[0003] Before the synthesis of traditional cyclopropanecarboxylic acid, the synthetic raw materials need to be dried. During the drying process, the raw materials are easy to accumulate together, resulting in poor drying effect of the raw materials at the bottom. Therefore, we propose a Raw material drying device for cyclopropanecarboxylic acid synthesis
