Abstract

The invention discloses a filter cake drying and collecting device for 2-methyl-5-pyrazinecarboxylic acid production, and relates to the field of filter cake drying. According to the technical scheme, the filter cake drying and collecting device comprises a drying box, penetrating grooves are symmetrically formed in the outer portion of the drying box, and a plurality of overturning mechanisms and a plurality of conveying belts are assembled in the drying box; the multiple overturning mechanisms and the multiple sections of conveying belts are distributed in a staggered mode, one side of each overturning mechanism is adjacent to the corresponding conveying belt, a buffering mechanism is adjacently arranged on the other side of each overturning mechanism, clamping rods are symmetrically installed in the drying box, and the outer portions of the clamping rods are slidably connected with mounting plates. A positioning mechanism used for dividing filter cakes into columns is arranged between the two mounting plates, guide plates are mounted outside the mounting plates, the distance between the column dividing plates can be adjusted by adjusting the positions of the mounting plates in the positioning mechanism, and then the filter cakes moving on the conveying belt can be evenly divided into columns. And the filter cakes can be conveniently collected through the collecting box.

Description

technical field [0001] The invention relates to the technical field of filter cake drying, in particular to a filter cake drying and collecting device for the production of 2-methyl-5-pyrazinecarboxylic acid. Background technique [0002] 2-Methyl-5-pyrazinecarboxylic acid is also called 2-methyl-5-pyrazineic acid, 5-methyl-2-pyrazinecarboxylic acid, 2-carboxy-5-methylpyrazine, 5-methyl Pyridine-2-carboxylic acid, 2-methylpiperazine-5-carboxylic acid, 2-methyl-5-pyrazinecarboxylic acid, 5-methyl-2-pyrazinecarboxylic acid, CAS number 5521-55-1, Molecular formula is C 6 h 6 N 2 o 2 , with a molecular weight of 138.12, the drug belongs to pharmaceutical intermediates, the intermediate of the drug glipizide, the intermediate of the blood lipid-lowering drug acipimox (lezhiping), it is stable at normal temperature and pressure, light yellow crystal, The melting point is 166-169°C. It needs to be stored in a cool and dry place, sealed. [0003] After searching, the Chinese ...
