Abstract
The present invention relates to a garbage separating method. The method comprises the steps of sieving, bag break, isolation and separation; the isolation step also comprises the step: water generates vortex flow, and centrifugal force generated by the vortex flow is used for forcibly isolating garbage. Because the method that the vortex flow is used for forcibly isolating the garbage is used, the separation efficiency of the garbage is increased, and the present invention is suitable for the bulk processing and the separation of the garbage. The present invention also relates to a system using the method of the present invention to separate the garbage. The system comprises a sieving mechanism, a bag breaker, a garbage separator, a mesh belt conveyor and an automatic control device, wherein the garbage separator is composed of a circular inner layer casing and an outer layer casing; a water flow spray pipe is arranged along a tangential direction at the top of the inner layer casing, and/or a water flow spray hole is arranged along a tangential direction at the side wall of the inner layer casing; water in the inner layer casing forms centrifugal vortex flow by spraying water flow, so the garbage in the water is driven to be forcibly delaminated.

Sorting utilizes the flow collection of water to be distributed in the rubbish of different liquid levels;
It is characterized in that: also comprise at described separating step making the water generates eddy current, and utilize the step of the centrifugal force pressure separating of garbage of eddy current generation.
Owing to adopted the method for utilizing eddy current to force separating of garbage, make the separative efficiency of rubbish be improved, be applicable to a large amount of processing and the sorting of rubbish.
In described sorting step, separation and collection rubbish can be finished in same device.
The method of sorting rubbish of the present invention can also comprise sterilization, sterilization, deodorization step.Rubbish through this step process can directly be recycled, and needn't worry to pollute once more.
Another object of the present invention is to provide a kind of system that adopts method sorting rubbish of the present invention.
The system of sorting rubbish of the present invention comprises:
Screening plant, constitute by aggregate bin and the first order macropore vibratory sieve, the second level aperture vibratory sieve that are obliquely installed in aggregate bin, the output of the described first macropore vibratory sieve links to each other with the Bulky Waste conveyer, the output of described second level aperture vibratory sieve links to each other with the bag-breaking machine arrival end, and described aggregate bin lower end is provided with opening and links to each other with the dregs gatherer;
Bag-breaking machine is the cylinder that arrival end is obliquely installed up, and its inwall circumference is provided with the broken bag cutter that together rotates with inwall;
The rubbish seperator is used for the separation of rubbish;
Wired belt conveyer is collected the rubbish that is separated by the rubbish seperator respectively, and is transported to gathering-device; And
Automaton is used for the automatic control of refuse classification process,
It is characterized in that:
Described rubbish seperator is made of circular internal layer shell and outer casing, tangentially be provided with the water flow jet pipe and/or the water flow jet hole tangentially be set at the top of internal layer shell at its sidewall, also being provided with guiding gutter at the sidewall of internal layer shell links to each other with accumulator tank, bottom at internal layer shell is provided with funnel, this funnel lower ending opening;
Described wired belt conveyer is arranged at respectively in the described accumulator tank, and between described funnel opening below and the described outer casing.
The current that spray in described water flow jet pipe or water flow jet hole can make the water generates eddy current in the rubbish seperator internal layer shell, and force drive rubbish that rubbish is separated in water, are distributed in different liquid levels; Simultaneously because the effect of eddy current, make the shunting of the vertical and horizontal both direction of water generates, the shunting of vertical direction drives weight, move down as earth, stone, metal, battery etc., collect conveying by the wired belt conveyer that is positioned at funnel opening below, the shunting of horizontal direction then drives the rubbish that is positioned at different liquid levels and flows, and collects conveying by being positioned at accumulator tank guipure sortation conveyor.Therefore can improve and separate and collection efficiency.
The guiding gutter of described rubbish seperator can be along the tangential direction setting of described inner sphere mechanism body sidewall, and its tangential direction is consistent with the tangential direction in described water flow jet pipe or water flow jet hole, can make the resistance of current littler like this.
Described bag-breaking machine is at least two groups at the broken bag cutter of inwall circumference setting, and the direction of rotation of two adjacent groups broken bag cutter is opposite.The broken bag cutter that rotation direction is opposite can make broken bag efficient increase, because the broken bag cutter can be carried and oppositely tear the realization broken bag, therefore the requirement to the broken bag cutter can reduce, and helps reducing cost cost saving.
Be positioned at each broken bag cutter shaft at described bag-breaking machine inwall and to side edge ball can be set, the height of ball is lower than edge of a knife 5CM.Ball is set prevents that rubbish from stopping up the edge of a knife.
