A kind of separation system using cement kiln synergic processing domestic waste, the plate including discharge bin bottom is arranged in The exit for feeding machine plate hello machine is equipped with harmonious material device, and the discharge port of harmonious material device is connected by the feed inlet of feed belt and the first crusher It connects；It further include rotary screen, magnetic separator, astrolabe sieve, the second crusher and pneumatic separator；The discharge port of first crusher connects roller Feed inlet is sieved, rotary screen discharge port is divided into oversize discharge port and screenings discharge port, and oversize discharge port connects magnetic separator I, Oversize enters the second crusher after magnetic separator I, and the discharge port connection astrolabe of the second crusher sieves I, screenings discharge port Magnetic separator II is connected, screenings enters astrolabe after magnetic separator II and sieves II, and the discharge port of astrolabe sieve I is divided into oversize discharge port Dehydration equipment, screenings discharge port I connection pneumatic separator II, star are compressed in I and screenings discharge port I, the I connection of oversize discharge port The discharge port of riddle II is divided into oversize discharge port II and screenings discharge port II, oversize discharge port II connection pneumatic separator I, The II connection of screenings discharge port pneumatic separator II, pneumatic separator I and pneumatic separator II include light components discharge port and heavy Component discharge port, the light components discharge port connection compression dehydration equipment of pneumatic separator I, the heavy component discharging of pneumatic separator I The light components discharge port connection compression dehydration equipment of mouth connection pneumatic separator II, pneumatic separator II, the heavy of pneumatic separator II Component discharge port connects cement kiln by transmission device.

Wherein, the material particular diameter of first crusher treated fragment is 150mm.

Wherein, the aperture of the rotary screen is 80*80mm, and tilt angle is 7 °, and revolving speed is 4~15rpm.

Wherein, for the astrolabe sieve I as the specification of astrolabe sieve II, aperture 36*44mm, tilt angle is -9 °~9 °, Revolving speed is that frequency conversion is adjustable.

Wherein, the utility model separation system further includes percolation liquid treating system, and discharge bin and compression dehydration equipment generate Percolate percolation liquid treating system be pumped to by submersible sewage pump handled.

The method for separating of the above-mentioned separation system using cement kiln synergic processing domestic waste, the specific method is as follows: The first crusher is successively transported to after plate feeds machine and harmonious material device after garbage-sorting in discharge bin, and the first crusher is by object Material is crushed to 150mm hereinafter, broken material is delivered to rotary screen by conveyer；Oversize after rotary screen sieves passes through Magnetic separator I sorts out magnetic material, and remaining non-magnetic material enters astrolabe after the second broken crusher machine and sieves I, astrolabe Oversize after sieve I screening enters as flammable raw material (energy) in compression dehydration equipment, and astrolabe sieves the screenings after I screening Into screenings pneumatic separator II；Undersize material after rotary screen screening is sieved by entering screenings astrolabe after magnetic separator II II, the oversize after astrolabe sieve II screening enter oversize pneumatic separator I, and the screenings after astrolabe sieve II screening enters screenings Pneumatic separator II；Resulting light components are used as combustible constituent to be sent into firing system as cement after carrying out compression dehydration after selection by winnowing Alternative fuel is produced, resulting heavy component is prepared as non-combustible subparticipation cement producting material after selection by winnowing.

The utility model has the advantages that the utility model separation system solve sorting consumer waste in the prior art be not thorough, resource benefit With the not high problem of rate, which has carried out effective sorting for domestic waste, the combustible (modeling sorted Material, paper, fabric, rubber, wood bamboo etc.) and noncombustibles (brick, tile fragment, glass, dregs, food waste etc.) purity reach 95% with On, plastic fraction is lower than 5% especially in noncombustibles, and thoroughly, the combustible and noncombustibles finished product after sorting are whole for sorting It can be utilized by cement kiln, realize the utilization of resources and recycling of combustible and noncombustibles 100%, and metropolitan wastes sorting The percolate and foul smell generated in the process can also be disposed well, realize domestic waste and thoroughly handle and zero-emission It puts, there is huge economic value and environmental benefit.

Detailed description of the invention

Fig. 1 is the systematic schematic diagram of the separation system of the utility model cement kiln synergic processing domestic waste.

Specific embodiment

Technical solutions of the utility model are described further in the following with reference to the drawings and specific embodiments.

The utility model is specifically included using the method for separating of the separation system of cement kiln synergic processing domestic waste Following steps:

S1, domestic waste enters after plant area is weighed by platform scale, and house refuse is by garbage truck down in discharge bin Storage, discharge bin bottom arranging plate feed machine feed system, and plate is fed machine feed system outlet setting harmonious material device homocline, passed through after homocline Belt feeder is delivered to the processing of the first crusher；

S2, gained fragment carries out rotary screen screening, the oversize after rotary screen screening after the first broken crusher machine Magnetisable material to be selected by magnetic separator I, remaining non-magnetic material enters astrolabe sieve I screening after the second broken crusher machine, Oversize after astrolabe sieve I screening removes compression dehydration equipment extrusion dehydration as combustible finished product, and astrolabe sieves under the sieve after I screening Object enters screenings pneumatic separator II；
