Kitchen waste is mainly waste generated in activities such as food processing, food service, and unit meal supply, among other activities, in daily living of residents. The kitchen waste is rich in nutritional ingredients, and mainly comprises starch, free sugar, protein, fat, cellulose, inorganic salt and the like. Therefore, the kitchen waste is extremely easy to deteriorate and rot, not only generates a large amount of toxins and emits malodorous gas, but also pollutes water and atmosphere, so that if the kitchen waste cannot be treated in time, the urban capacity and the environmental sanitation are affected, diseases can be transmitted, and the daily life and the physical health of people are endangered.
With the progress of technology, in terms of the current situation, the kitchen waste is mainly treated by the following treatment modes:

Through rabbling rotational flow effect of rabbling mechanism, solid impurity such as gravel sink to impurity collection appearance chamber, and the vertical size in this application is greater than horizontal size in impurity collection appearance chamber, can prevent that these solid impurity from being rolled up once more, has shortened the time of degritting. Preferably, the impurity collecting cavity is in a hollow column shape.
The sand setting device comprises an upper cylinder body and a lower cone body, and the impurity collection cavity is communicated with the bottom of the lower cone body; the discharge port of the sand setting device is arranged on the lower cone, and the feed port of the sand setting device is arranged on the upper cylinder. The cross section area of the lower cone body gradually becomes smaller from top to bottom, and impurities can be accelerated to enter the impurity collecting cavity under the action of rotational flow. And because the longitudinal dimension of the impurity collecting cavity is larger than the transverse dimension, the impurities entering the impurity collecting cavity are not easy to roll up again.
The stirring mechanism comprises a stirring shaft which is longitudinally arranged, and a plurality of stirring blades are alternately arranged on the stirring shaft from top to bottom. The stirring blades are longitudinally arranged, so that kitchen waste in the sand setting device is more uniform, and the sand removing effect is better. Solid impurities enter the impurity collecting cavity under the action of gravity and rotational flow, and in order to prevent the stirring vane from being arranged at a position too close to the bottom of the lower cone body and generating excessive rotational flow so as to influence the sedimentation of the impurities, the stirring vane at the lowest position corresponds to the middle upper position of the lower cone body. Thus, not only the impurity removal efficiency is ensured, but also the impurity removal effect is ensured.
