Fine anthracene filter

The invention relates to the technical field of anthraquinone production equipment, in particular to a refined anthracene filter. Comprising a container body, a refined anthracene inlet, a refined anthracene outlet, a heat-conducting medium inlet, a heat-conducting medium outlet, a filtering device and a cover. The container body is of a vertical jacket structure and comprises an inner body and an outer body sleeved outside the inner body, and a gap is reserved between the inner body and the outer body to form an interlayer. The refined anthracene inlet is fixedly connected to the upper part of the inner body and communicated with the interior of the inner body; the refined anthracene outlet is fixedly connected to the bottom of the inner body and is communicated with the interior of the inner body. The heat-conducting medium inlet is fixedly connected to the upper part of the outer body and communicated with the interlayer; the heat-conducting medium outlet is fixedly connected to the bottom of the outer bod
