Problems solved by technology

[0006] 1. It is mainly the extrusion and conveying process, without rough processing such as bag breaking, sieving out slurry, and oil heating;
[0007] 2. The bag breaking efficiency of the garbage bag is low, resulting in a part of the available slurry will follow the garbage bag and be discharged from the overscreen pipeline, making it unusable;
[0008] 3. There is no heating component, and the grease fluidity is poor when the ambient temperature is low, and it is easy to be discharged from the oversieve pipeline along with the garbage;
[0009] 4. The overall utilization rate of organic matter is not high

Embodiment 1

[0067] Example 1: The garbage truck is transported to the unloading hopper, the cover plate assembly 3 is opened by the oil cylinder 31 through the automatic control system, and the garbage truck unloads the kitchen waste into the unloading hopper; the pushing component 2 in the unloading hopper pushes the kitchen garbage To the barrel assembly 5; the kitchen waste is processed by the bag breaking blade 412, the slice 413 and the stirring blade 414 in sequence in the barrel assembly 5, and a large amount of slurry is screened out, wherein the first mixer 41 and the third mixer 43 are stirred clockwise, The second mixer 43 and the fourth mixer 44 stir counterclockwise to push the material forward; the cylinder body assembly 5 is provided with a heating assembly 53, and the heating assembly 53 uses high-temperature steam to heat the slurry to make the oil and kitchen waste liquid phase; the slurry passes through the cylinder The lower sieve plate enters the liquid collecting devi...

Embodiment 2

[0068] Example 2: Since the sand contained in the slurry will be hardened due to a long precipitation time, during the normal slurry discharge process, the slurry outlet and slurry outlet and backwash components 7 should be opened to ensure that the slurry in the funnel is not easy to precipitate. Stand still. Specifically, open the electric regulating valve 71, open the electric switch valve 72, close the electric switch valve 73, open the electric switch valve 74, and open the slurry pump 75, some of the slurry will self-circulate in the pipeline, and some will be discharged from the discharge pipeline. When it is used to backflush the bottom sand discharge pipe, open the electric regulating valve 71, close the electric switch valve 72, open the electric switch valve 73 and the electric switch valve 74, the flushing water enters the sand discharge pipe through the feed pipe, and the backwash slurry flows from the outlet. material pipe out.

The screw assembly is connected to one side of the barrel assembly. The invention can efficiently process the kitchen garbage and improve the utilization rate of organic matters.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a broken bag sorting device and method for the treatment of kitchen waste. Background technique [0002] With the progress of garbage classification, the recycling of kitchen waste is also on the right track. The composition of kitchen waste is very complex. It is a mixture of various substances such as water, oil, fruit peel, vegetables, rice noodles, waste tableware, plastics and paper towels. It is characterized by high water content, rich in organic matter and oil, and high salt content. The recycling of kitchen waste on the market is mainly used for fermentation to generate biogas, and for the extraction of kitchen waste grease in the slurry, which is used for industrial lubrication, combustion and other functions. [0003] At present, the existing front-end process layout of kitchen waste treatment is only a screw feeding device driven by a hydraulic motor, and there...
