Operation principle:
1 filtration circuit:
In filter chamber 03, Fig. 1 right side, material is to adopt bottom in and top out, the filtering technique route that goes out in entering outward. Need the high-viscosity material melt filtering to enter filter chamber's 03 inner chamber from filter chamber's 03 foot passage, before filter under the effect of pressure P 1, melt enters into outer guiding gutter by the pod apertures of outer flow guiding disc 09 external diameter, and then is full of all spaces that can arrive in filter chamber 03. Because outer guiding gutter two sides are equipped with supporting network 11 and screen pack 10, now some large particles and gel particles are just blocked in the another side of screen pack 10, do not have the material of impurity to flow in the interior guiding gutter of interior flow guiding disc 08 by supporting network 11 and screen pack 10. Material after filter has a pressure differential Δ P when through screen pack 10. Therefore pressure P 2=P1-Δ P after filter, after filter, material flows to pod apertures under the effect of P2 from the interior guiding gutter of interior flow guiding disc 08, then flow into the surface of antipriming pipe from pod apertures, finally flow in central passage by the lip-deep through hole of antipriming pipe again, because antipriming pipe is to be contained in 03 li of filter chamber, material flows to the crusher discharge end cover on 03 top, filter chamber again from the central passage of antipriming pipe, then flow out from the passage of crusher discharge end cover.
