Abstract

The invention relates to a filter disk which comprises a disk filter and a disk shell, wherein the disk filter comprises a filter net, a disk inner ring and a disk outer ring; the filter net is divided into an upper filter net and a lower filter net; two ends of the upper and lower filter nets are separately arranged on the upper and lower surfaces between the disk inner and outer rings; the disk shell comprises a disk supporting frame and a supporting frame connection ring; the disk supporting frame consists of a certain quantity of disk supporting rods; one end of each disk supporting rod is connected with the upper surface of the disk outer ring, and the other ends of the disk supporting rods are connected with the supporting frame connection ring and are uniformly distributed on the upper surface of the disk filter to divide the upper surface of the disk filter into fan-shaped regions; and small holes are formed in the wall of the disk inner ring. The filter disk can effectively eliminate a dead corner region of melt flowing, so that a melt can smoothly flow in the region, so as to avoid degradation caused by long-time retention of the melt; and the problem of melt retention of an original PALL disk is effectively solved.

Description

Technical field [0001] The invention relates to a filtering device, in particular to a filter disc for polyester melt. Background technique [0002] The polyester film production line needs to use a melt filter to filter the impurities in the melt, and the filtered melt enters the film production. The filtering effect of the melt filter directly affects the normal production and internal quality of the film. [0003] The melt filter is mainly composed of three parts, namely the filter housing, the disc and the filter core tube. The filter housing is a cavity structure. The filter discs are sleeved on the filter core tube according to a certain number and stacked structure. Sealing gaskets are installed between the discs and are sealed inside the cavity. It is composed of bolts and sealing rings. Tightly combined, there is an inlet flow channel for the melt to enter the filter under the filter, the melt enters the middle flow channel of the filter core tube after being filtered by...
