Compared with the prior art, the wire-mesh-free filter has the following advantages:
1. the waste residues such as impurities left after filtration are not directly discharged, but the impurities are pushed out and then discharged in a screw rod rotating mode, because the temperature of a molten plastic mixture is generally higher and can reach about 200 ℃, the molten plastic which really needs to be recycled is in a liquid fluid state, the impurities such as sand, iron, copper, aluminum and the like are in a solid state, in the rotating process of the screw rod, because the molten plastic is in the liquid fluid state, the molten plastic can flow back under the rotating pushing of the screw rod, the solid impurities such as sand, iron, copper, aluminum and the like can be pushed forward, the impurities containing the molten plastic fluid are further separated, the solid impurities such as sand, iron, copper, aluminum and the like are pushed forward to be accumulated at the front end of the screw rod, the molten plastic fluid in the screw rod can flow back to be concentrated at the rear end of the screw rod, and then the molten plastic fluid accumulated at the rear end of the screw rod can be carried to a filter plate for secondary filtration to a certain degree under the back-and forth movement of the scraper plate, meanwhile, the molten plastic fluid accumulated at the rear end of the screw partially overflows to the filter plate for secondary filtration after being accumulated to a certain degree, so that the molten plastic fluid is further filtered into the discharge cavity, and the recovery rate of the plastic is improved;
2. the waste discharge valve structure is arranged, so that waste materials such as impurities are discharged periodically instead of at any time, firstly, the waste materials such as the impurities are discharged uniformly after waiting for a certain time at the discharge port, a cooling device is not required to be arranged at the discharge port, and the impurities are naturally cooled within a certain waiting time, so that the structure is simplified, and the cost is reduced; secondly, when the screw pushes impurities to move towards the discharge port, the impurities in front are blocked by the partition plate of the waste discharge valve structure, the molten plastic fluid mixed in the impurities in front is pushed by the screw, the solid impurities such as sand, iron, copper and aluminum and the like pushed by the screw in front are pushed, the molten plastic fluid mixed in the impurities in front is pushed by the partition plate in front and the solid impurities such as sand, iron, copper and aluminum and the like in front are separated, the molten plastic fluid mixed in the impurities in front is pushed by the solid impurities such as sand, iron, copper and aluminum and the like pushed by the screw in front and is pushed to the back of the pushed solid impurities such as sand, iron, copper and aluminum and the like towards the two sides of the solid impurities, and the solid impurities such as sand, iron, copper and aluminum and the like pushed by the screw in back are pushed to the partition plate until the solid impurities are blocked by the partition plate; therefore, the arrangement of the waste discharge valve structure enables the solid impurities to be continuously extruded to the partition plate, the molten plastic fluid is continuously extruded to the rear part and is continuously close to the screw, and the extruded molten plastic fluid continuously moves to the rear end of the screw by combining the screw structure, so that the recovery rate of the plastic is further improved;
3. this filter has adopted bilateral symmetry's two sets of filtration, the structure of wasting discharge, has improved and has filtered the efficiency of wasting discharge, and simultaneously, the rotation direction of its first screw rod and second screw rod is opposite, is equivalent to that first screw rod and second screw rod are offset each other to the effort of box to the unstable vibrational force of rotation to the box production of first screw rod and second screw rod has been avoided, makes box work more stable.
