As preferably, the quantity of described material reducing rod is seven.The quantity of the quantity of cartridge filter and material reducing rod is thought etc., seven cartridge filters are arranged and can be obtained comparatively ideal space availability ratio, not only can obtain 7 times of above filter efficiencies, and simple in structure, compact, manufacturing cost, unpick and wash cost and can significantly reduce, overall economic efficiency is very considerable.
As preferably, described seven material reducing rods spacing each other equates with the external diameter of feeding cylinder.Can, so that seven feeding cylinders can close-packed arrays, further improve space availability ratio like this; Can simplify the kind of the excellent and relevant spare and accessory parts of material reducing, increase interchangeability, reduce manufacture, use cost simultaneously.
As preferably, described material reducing rod is provided with chamfering towards one end of porous reclaiming plate outer circumferential side.The outer peripheral face that is arranged so that material reducing rod of chamfering to the gap clearance between the inner peripheral surface of cartridge filter can further be dwindled, and the raw material hold-up on cartridge filter also can obtain further minimizing, and overall economic efficiency can further be optimized.
This
utility modelbeneficial effect be: due to seven cartridge filters that wait external diameters being set on die head of plastic extruding machine; in each cartridge filter, be provided with corresponding material reducing rod; make plastic extruder can avoid frequent shutdown to unpick and wash; reduce waste of raw materials; save the energy; good filtration effect, and unpick and wash convenient and swiftly, overall economic efficiency is very considerable.
