In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.
The invention provides a circulating household garbage separating system, which comprises a crushing and screening mechanism, a separating mechanism, a sludge treatment mechanism, an oil-water separator and a water circulating component, as shown in figure 1; the crushing and screening mechanism can transport the crushed garbage to the separating mechanism, the separating mechanism can separate the garbage with different densities, the sludge treatment mechanism and the oil-water separator can further treat the separated garbage, and the water circulation component is connected with the oil-water separator and the crushing and screening mechanism, so that an inner circulation system is formed among the crushing and screening mechanism, the separating mechanism, the sludge treatment mechanism and the oil-water separator.
Wherein, the crushing and screening mechanism comprises a crusher 11, a conveyor 12, a fan 13, a ball mill 14, a screening machine 15 and a belt conveyor 16. The feed inlet of the ball mill 14 is connected with the crusher 11 through the conveyor 12, the conveyor 12 can convey the garbage crushed by the crusher 11 into the ball mill 14, the blower 13 can blow air to the ball mill 14, and the discharge outlet of the ball mill 14 is provided with the screening machine 15. The garbage is ground by the ball mill 14 to form paste and fine particles (about 200 meshes), and the paste and the fine particles are discharged into the separation mechanism from a slag discharge hole at the tail end of the ball mill 14. The refuse which is not easily ground is discharged from the end of the ball mill 14 into the screening machine 15. The screening machine 15 and the discharge gate of ball mill 14 are linked into an organic whole, synchronous revolution work, be greater than the rubbish of screening machine 15 sieve mesh passes through belt conveyor 16 sends into the compressor 17 packing is retrieved, and the rubbish that is less than the sieve mesh sends into metal separation machine through the plane conveyer under sieving, and metal recovery recycle, other waste incineration or landfill.
The separation mechanism comprises a grit chamber 21, a stirrer 22, an underwater conveyor 23, an automatic mechanical grid 24 and a solid-liquid separator 25. The stirrer 22 is arranged in the grit chamber 21 and is used for stirring the garbage discharged into the grit chamber 21 from the slag discharge hole at the tail end of the ball mill 14, after the garbage is stirred, the garbage with the density smaller than that of water floats on the water surface in the grit chamber 21 or is suspended in the water, and the garbage with the density larger than that of the water sinks into the bottom of the grit chamber 21.

The separated sewage flows into the oil-water separator 34 to be subjected to grease separation and grease recovery, and the sewage is reused in the ball mill 14 through the water circulation assembly. Specifically, the water circulation assembly comprises a pipeline 41 and a water pump, wherein one end of the pipeline 41 is connected with the ball mill 14, the other end of the pipeline is connected with the oil-water separator 34, and the water pump can pump the oil-water separator 34 into the ball mill 14.
The centrifuge 33 described above may be an H1750 desk-top high-speed centrifuge; the oil-water separator 34 may be a mobile oil-water separator manufactured by san machinery equipment manufacturing ltd, shanghai.
For ease of understanding, the workflow of the present invention is again set forth below: the household garbage enters a crusher 11 to be crushed into small-particle garbage, then the small-particle garbage is conveyed into a ball mill 14 by a conveyor 12 to be ground, water and wind are added during ball milling, the fragile and perishable garbage is ground into paste and fine particles of about 200 meshes, and the paste and the fine particles are discharged into a grit chamber 21 from a slag discharge hole at the tail end of the ball mill 14. Garbage which is not easy to grind is discharged into a screening machine 15 from a central hole at the terminal of the ball mill 14, the screening machine 15 and a discharge hole of the ball mill 14 are connected into a whole and synchronously rotate, the garbage which is larger than a sieve pore of the screening machine 15 is sent into a compressor 17 through a belt conveyor 16 to be packed and recycled, the garbage which is smaller than the sieve pore of the screening machine 15 is sent into a metal separator through a plane conveyor arranged at the lower part of the screening machine 15, and the metal is recycled and other garbage is burned or buried. The grit chamber 21 and the concentration tank 31 form a circulating body. And (3) circulating the water in the tank, after the perishable garbage and the ground fine particles enter the grit chamber 21, stirring to enable the garbage with the density higher than the water density to sink to the bottom of the grit chamber 21, and fishing out the garbage sinking to the bottom of the grit chamber 21 from the surface of the grit chamber by using an underwater conveyor 23 for landfill or brick making. The garbage with the density less than the water density is in a suspension or floating state, and the garbage with the particle size more than 5mm is brought to the automatic mechanical grating 24 along with the flow of water, is captured by the grating, is fished out of the water surface, and is compressed for landfill. The garbage which is less than 5mm and is in a suspension state enters a concentration tank 31 through a grid gap, concentrated dirt is subjected to solid-liquid separation through a centrifugal machine 33, and the separated solid matter can be prepared into the organic fertilizer through microbial fermentation. The separated sewage flows into an oil-water separator 34 to separate oil and fat, the oil and fat are recovered, and the sewage is recycled to the ball mill 14.
The whole system has no sewage discharge in the operation process, each treatment section can operate in a totally-enclosed way, the waste water, the waste gas and the noise can be controlled and treated, and no secondary pollution is generated in the whole system.
The preferred embodiments of the present invention have been described in detail, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
