Description

Technical Field

[0001] This utility model relates to the field of solvent recovery technology in the synthesis of 2-ethylanthraquinone, and specifically to a filtration device for solvent recovery in the synthesis of 2-ethylanthraquinone. Background Technology

[0002] Solvents are essential in the synthesis of 2-ethylanthraquinone. However, the consumption and emission of solvents not only increase production costs but also pollute the environment. Therefore, solvent recycling is of great significance for improving economic efficiency and protecting the environment.

[0003] In the synthesis of 2-ethylanthraquinone, solvent filtration is a crucial step. It helps remove impurities from the solvent, improves its purity, and ensures the smooth progress of subsequent synthesis steps. The pretreated solvent is poured into the filtration equipment, which is then turned on to allow the solvent to pass through the filter medium.

[0004] In the above filtration process, the solvent passes through the center of the filter medium, while the edges of the filter medium do not participate in the filtration task. This not only reduces the overall filtration effect, but also shortens the service life of the filter element due to uneven filtration, resulting in inconvenience in use. Utility Model Content

[0013] Further, the uniform dispersion assembly further comprises a driving motor vertically arranged on the top of the feeding cylinder, the output end of the driving motor is vertically arranged on the top of the dispersion disc.

[0014] Compared with the prior art, the technical scheme has the following beneficial effects:

[0015] 1. The filter element is detachably arranged in the filter cavity to filter the solvent, and the feeding hopper is arranged at the cavity opening of the filter cavity, so that the solvent entering the filter cavity from the feeding hopper will first fall on the central position of the dispersion disc, and the rotation of the dispersion disc and the centrifugal motion of the plurality of fan blades on the dispersion disc will splash the solvent to the edge of the dispersion disc, so that the solvent can uniformly pass through the filter element below due to the action of gravity, thereby improving the use efficiency of the filter element and the filtering efficiency of the filter element.
