Abstract
The invention discloses an on-line circulating utilization device for a filtering net of a plastic extruder. The on-line circulating utilization device mainly comprises a melt feeding opening, an outer ring, an inner ring, a porous plate, a bottom plate, a cover plate, an after-filtering plate, the filtering net, a before-filtering cavity, an after-filtering cavity, a melt outlet, an air knife, a recycling material outlet and an impure material recycling cavity. The on-line circulating utilization device has the beneficial effects that a barrel-shaped structure as the filtering net is connected end to end is designed so that the filtering net is pushed by kinetic potential of a melt extruded by the extruder or is driven by a roller A and a roller B to move along the surface of the outer circle of the inner ring so that part of the filtering net, working on the before-filtering cavity and having impurities, is moved to the air knife to blow off the impurities by high-speed gas; parts of the filtering net, without the impurities, is moved to the before-filtering cavity to work; the filtering net is used for filtering and blowing off the impurities in the on-line circulating process so that the filtering net does not need to be frequently replaced; the working efficiency is improved and electric energy is saved; the labor intensity of workers is also greatly relieved.
