The invention discloses a device and a method for double-stage suction filtration of 1-aminoanthraquinone. The double-stage suction filtration device comprises a vacuum pump, a filtering bin and a negative pressure bin; the filtering bin is arranged above the negative pressure bin, and filtering assemblies are arranged between the filtering bin and the negative pressure bin; the vacuum pump is communicated with the negative pressure bin through a guide pipe; and the double-stage suction filtration device completes secondary suction filtration work of the 1-aminoanthraquinone through multiple steps. The double-stage suction filtration device can be used for carrying out secondary suction filtration on a mother liquor containing 1-aminoanthraquinone, and the primary filtering assembly can complete continuous filtering control, so the filtering efficiency of a filter element is improved; the secondary filtering assembly can pop up 1-aminoanthraquinone sinking into filtering holes of the secondary filtering assembly through up-down reciprocating motion of a filtering net to prevent the filtering net from being blocked, so the filtering efficiency of the filtering net is improved; and the primary filtering assembly and the secondary filtering assembly are arranged in a matched manner, so that the filtering rate of the double-stage suction filtration device on the 1-aminoanthraquinone is increased, and the suction filtration efficiency of the double-stage suction filtration device is also improved.
Description
technical field [0001] The invention relates to a suction filtration device and method, in particular to a 1-aminoanthraquinone secondary suction filtration device and method. Background technique [0002] 1-Aminoanthraquinone is an important intermediate in the synthesis of anthraquinone dyes. It has a wide range of uses and high consumption, and occupies an extremely important position in the dye industry. In the process of preparing 1-aminoanthraquinone, after the mother liquor containing 1-aminoanthraquinone is finally obtained, the 1-aminoanthraquinone crystals are separated from the mother liquor by suction filtration. Suction filtration, also known as decompression filtration and vacuum filtration, refers to the use of a suction pump to reduce the pressure in the suction filter tank to achieve the purpose of solid-liquid separation. [0003] At present, the existing suction filtration device uses a vacuum pump to perform decompression suction filtration, connects the...
