A polyethylene production and processing filtration device

Abstract

This utility model relates to the field of polyethylene processing technology, specifically a polyethylene production and processing filtration device, including a filter box. A conical filter cylinder is fixedly installed in the middle of the filter box. A centrifugal auxiliary component for centrifugal cyclone-assisted filtration is provided both inside and outside the filter box. The centrifugal auxiliary component includes a drive motor fixedly installed at the top of the filter box. The output end of the drive motor passes through the filter box and is fixedly connected to a transmission shaft. Two centrifugal fan plates are fixedly installed at the corresponding positions of the transmission shaft and the filter cylinder. The drive motor in this utility model can drive the transmission shaft and the centrifugal fan plates to rotate. Through the centrifugal force generated by the rotation, large particles are thrown to the outside of the filter screen instead of directly adhering to the filter pores, forming a loose filter cake layer or depositing on the outer wall of the filter screen. This reduces the risk of direct clogging of the filter pores and extends the effective filtration time of the filter screen. It also avoids the problem of large particles directly contacting the filter screen surface and easily getting stuck in the filter pores, causing clogging.
