Filter device and filter extruder head containing the same

Abstract

The invention belongs to the technical field of filter devices, and relates to a filter device for a plastic granulator and a filter extruder head containing the filter device: a filter device is formed by a plurality of filter groups evenly distributed on a substrate to form a filter net, and each filter group A number of filter holes are arranged at intervals, and the outer contour of each filter group is a geometric figure; the filter extrusion head is at least one side wall of a cylindrical or rectangular shell as the filter device, and the shell and filter device The inner filter cavity is formed, and the shell wall or / and the top cover of the shell are provided with a feed port or a feed channel, and a material extruding device is set in the filter cavity, and the underside of the shell is sequentially provided with a miscellaneous storage cavity, a discharge The miscellaneous port and the miscellaneous discharge valve are installed on the miscellaneous discharge port. There is a heating device inside or outside the shell wall. The advantages are: good filtering effect, non-stop cleaning, suitable for various specifications and models of recycled plastics Granulator.

Description

technical field [0001] The invention belongs to the technical field of filter devices, in particular to a filter device for a recycled plastic granulator and a filter extruder head containing the filter device. Background technique [0002] At present, the raw materials used for granulation by recycled plastic granulators generally use waste plastics such as waste plastic bags and waste plastic cloths as raw materials. , some impurities mixed with lime sand isosceles to block the filter screen, so that the equipment cannot work normally. The solution is to stop the machine to remove the impurities and continue production. Every time the impurities are removed, a large amount of them needs to be burned (wasted) and left in the equipment. The plastic raw material in the cavity is labor-intensive, time-consuming, and has low production efficiency and high production cost. Contents of the invention [0003] The purpose of the present invention is to provide a filtering device...
