Background

The kitchen waste machine is an environment-friendly device for realizing kitchen waste reduction by simulating the digestion principle of human stomach. By means of simulating gastric peristalsis through mechanical movement, the biological strains in the kitchen waste machine simulate the principle of gastric juice, and the kitchen waste is decomposed into water (the decomposed water contains impurities such as shells, egg shells, crude fibers, bone residues, silt, sludge, suspended matters and the like). The water after the kitchen waste is treated through biodegradation needs to flow to the bottom device from a small filtering hole in the middle of the kitchen waste machine, then the bottom device is washed through the side face of the nozzle, the water with the degraded organic matters in the bottom device and a small amount of impurities and the like are thoroughly discharged out of the kitchen waste machine, and subsequent treatment is carried out, such as coarse separation of slag in waste water and the like.

If the range is exceeded, there will be a leakage phenomenon after a period of use. However, in the actual use process, because the welding process of the stirring cabin and the stirring shaft is difficult to control, the roughness and the eccentricity of the stirring shaft can exceed the range of the framework oil seal, and all equipment can leak water after being basically used for two months, so that the maintenance is needed.
