Therefore, during the processing of resin materials, it is usually necessary to filter them through a filtering device. The existing filtering device usually includes a cylinder body and a filter barrel arranged in the cylinder body. A filter screen is arranged in the filter barrel, and a certain gap is left between the outer wall of the filter barrel and the inner wall of the cylinder body. It is necessary to fix the filter barrel in the cylinder body through a fixing mechanism, and ensure that there is a certain gap between the outer wall of the filter barrel and the inner wall of the cylinder body to ensure its filtering effect.

The filter device of the utility model can perform secondary filtration and is a resin filter device that is easy to clean the filter screen; this structure facilitates the cleaning of the filter screen to a certain extent and increases work efficiency, but resin residue is likely to remain inside the connecting pipe, affecting the efficiency of the resin entering the next filter device.
