COMBINED WET-DRY CLASSIFICATION SYSTEM FOR MUNICIPAL HOUSEHOLD WASTE

摘要

Disclosed is a combined wet-dry classification system for municipal household waste, comprising a dry-type fragmentation and pneumatic classification apparatus and a wet-type water separation apparatus, wherein the dry-type fragmentation and pneumatic classification apparatus comprises a feed inlet (1), a fragmentation compartment (2), a sieve (6), a pneumatic classification chamber (7), and a self-adaptive conveyor belt (9); a slow rotating cutter (3) and a fast rotating cutter (4) rotating in the same direction are provided adjacent in the fragmentation compartment, the slow rotating cutter being mounted directly below the feed inlet; a blower (8) is mounted at the left-hand side of the pneumatic classification chamber; the wet-type water separation apparatus comprises a pool (10), a feed inlet (11) provided at the front of the right-hand side of the pool, a support (12) provided above the pool, a baffle plate (13) fixedly provided on the support, a fragmenting blade (14) and a checking and selection apparatus (15), a water inlet pipe (16) provided at the left end of the pool, an overflow port (17) provided in the middle part of the pool wall at the right-hand rear end of the pool, a circulating water pump (19), a filter mesh (18), a material outlet (21), a deflector (22) and a sediment outlet helix (23); and the circulating water pump is in communication with the pool via a circulating water pipe (20). The system can be used for problems such as waste easily intertwining and jamming when fragmenting, can run continually, can completely separate corrosive organic matter, light-weight combustible matter, and inorganic matter, and the moisture content of the light-weight combustible matter is reduced.
