Compared with the prior art, the waste discharge device of the non-wire mesh 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 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 recovered 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, because the molten plastic is in the liquid fluid state, the molten plastic can flow back under the rotating pushing of the screw, 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, and the molten plastic fluid in the screw flows back to be concentrated at the rear end of the screw, and can be filtered and recovered after being concentrated at the rear end of the screw, thereby further filtering the portion of the molten plastic flow into the discharge chamber, thereby increasing the recovery of plastic;

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 solid impurities to be continuously extruded to the partition plate, the molten plastic fluid can be continuously extruded to the rear part to be continuously close to the screw rod, and the molten plastic fluid extruded back by combining the screw rod structure continuously moves towards the rear end of the screw rod, so that the recovery rate of the plastic is further improved.

The wire-mesh-free filter has the following advantages:

1. two groups of filtering and waste discharging structures which are bilaterally symmetrical are adopted, so that the filtering and waste discharging efficiency is improved, and meanwhile, the rotating directions of the first screw and the second screw are opposite, which is equivalent to that the acting forces of the first screw and the second screw on the box body are mutually offset, so that the unstable vibrating force generated by the rotation of the first screw and the second screw on the box body is avoided, and the box body works more stably;
