Abstract

The invention discloses a smashing and separating machine for kitchen rubbish. The smashing and separating machine comprises a shell assembly, a feeding inlet, a starch outlet, a slag hole connected on the shell assembly, a machine power assembly, a conical screw for connecting a mechanical transmitting device, a variable screw pitch helical blade and a fixing blade spirally formed an angle together with the screw. An outer filter screen comprises two layers of mesh screens, wherein the meshes on the filter screen are regularly distributed and the size of the mesh can be regulated by regaling the relative positions. A screw clearance regulating unit is positioned on the tail end of the screw. The size of the outlet area of the screw is determined by the clearance size. After the kitchen rubbish is treated by using the smashing and separating machine, the materials having a grain size less than 5 mm in the starch are not less than 95%, the suspended biomass which is difficult to be anaerobic digested and some small grains, such as metal, plastic, and the like, which can not be anaerobic digested are separated so the anaerobic digestion of the kitchen rubbish is stably and efficiently performed.

Description

technical field [0001] The invention relates to anaerobic digestion pretreatment equipment for food waste, in particular to equipment for re-crushing the slurry of the food waste after traditional mechanical crushing and separating slag juice from the slurry. Background technique [0002] There is a large amount of kitchen waste, which has great potential hazards. At present, the anaerobic digestion of food waste is a research hotspot in various countries and regions in recent years. This method uses the biodegradation of microorganisms to convert most of the organic matter into biogas. After anaerobic fermentation, the biogas residue and biogas slurry are stabilized and can be used as high-quality organic fertilizers. In this way, the harmless treatment and resource utilization of kitchen waste can be realized. [0003] The composition of food waste is very complex. In addition to biodegradable materials, it also contains many non-biodegradable substrates, such as metals...
