Description
Technical Field
The utility model relates to a kitchen garbage processing apparatus especially relates to a kitchen garbage sand removing device.
Background
The kitchen waste mainly refers to waste generated in daily life of residents and other activities such as food processing, diet service, unit meal supply and the like. The kitchen waste is rich in nutrient components, 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 gases, but also pollutes water and atmosphere, so that if the kitchen waste cannot be treated in time, the urban and urban environments and the environmental sanitation are affected, diseases can be spread, and the daily life and the body health of people are harmed.
With the progress of technology, in view of the current situation, the treatment of the kitchen waste mainly comprises the following treatment modes:
1. and (3) fertilizer treatment: the treatment of the kitchen waste into fertilizer mainly comprises two treatment processes of aerobic composting and biogas sludge after anaerobic biogas production, and the composting and the biogas sludge are made into fertilizer.
2. And (3) feed treatment: the feed treatment of the kitchen waste is to convert the kitchen waste into high-calorie animal feed by utilizing a large amount of organic matters contained in the kitchen waste and crushing, dehydrating, fermenting and drying the organic matters.
3. Energy regeneration treatment: the energy treatment of the kitchen waste mainly comprises an incineration method, a thermal decomposition method, anaerobic biogas production and the like.
4. Alcohol fermentation of kitchen waste: after the kitchen waste is subjected to impurity removal, organic materials are fermented to produce alcohol.
In view of the above technologies, the method comprises the step of pretreating the kitchen waste. Because the kitchen waste has wide sources and complex components, more or less in the centralized treatment process of the kitchen waste contains gravels, metals, ceramics, glass, bones and other impurities with large specific gravity which are not beneficial to subsequent treatment, and in order to be beneficial to subsequent treatment, the impurities need to be separated from the kitchen waste.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at overcoming the not enough of prior art, provide a separator that can effectively separate metal, gravel, pottery, glass, bone etc. bulk density impurity from kitchen garbage.
In order to solve the technical problem, the utility model discloses a following scheme realizes:
the utility model provides a kitchen garbage sand removing device, includes the sand setting ware, the sand setting ware is equipped with feed inlet and discharge gate, is equipped with rabbling mechanism in it, and its bottom is equipped with the impurity collection appearance chamber that is used for collecting impurity, the vertical dimension that the appearance chamber was collected to impurity is greater than horizontal size, and is equipped with the bin outlet. Through rabbling mechanism's stirring whirl effect, solid impurity such as grit sinks impurity and collects and holds the chamber, and the vertical dimension that holds the chamber is collected to impurity in this application is greater than horizontal size, 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 cylindrical shape.
The sand setting device comprises an upper cylinder and a lower cone, and the impurity collecting cavity is communicated with the bottom of the lower cone; the discharge hole of the sand setting device is arranged on the lower cone body, and the feed hole of the sand setting device is arranged on the upper barrel body. The cross section area of the lower centrum is gradually reduced from top to bottom, and impurities can be accelerated to enter the impurity collecting cavity under the action of the 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. Stirring vane also is vertical setting promptly, can make the kitchen garbage in the sand setting ware more even, and the degritting effect is better. Solid impurities enter the impurity collecting cavity under the action of gravity and rotational flow, and in order to prevent the excessive rotational flow generated at the position where the stirring blade is arranged, which is too close to the bottom of the lower cone, from influencing the sedimentation of the impurities, the stirring blade at the lowest part corresponds to the middle-upper part of the lower cone. Therefore, impurity removal efficiency and impurity removal effect are ensured.
The feed inlet of the sand setting device is arranged at the top of the sand setting device, and a material crusher is arranged on the feed inlet. The kitchen waste is wide in source and different in size, the kitchen waste is firstly crushed and then is separated from impurities, and the separating effect is better.

Because this application adopts twice broken step, in order to facilitate the smooth second breakage that passes through of the material after the first breakage. Go up the cavity and be perpendicular UNICOM's form with lower cavity, first rubbing crusher constructs the setting and is being close to the position of going up the cavity feed inlet, second rubbing crusher constructs the setting and is being close to the position of lower cavity discharge gate. The materials crushed for the first time can directly fall onto the second crushing mechanism under the action of gravity, so that the moving resistance of the materials is reduced, and the energy consumption of material transportation is also reduced.
In order to improve the crushing effect, the first crushing mechanism comprises a first fixed cutter set and a first movable cutter set, the first fixed cutter set comprises a plurality of first fixed blades which are fixedly arranged and mutually spaced, the first movable cutter set comprises a plurality of first movable blades which are rotatably arranged and mutually spaced, and the first fixed blades and the first movable blades are alternately staggered; the second crushing mechanism comprises a second fixed cutter set and a second movable cutter set, the second fixed cutter set comprises a plurality of second fixed blades which are fixedly arranged and spaced from each other, the second movable cutter set comprises a plurality of second movable blades which are rotatably arranged and spaced from each other, and the second fixed blades and the second movable blades are alternately staggered; the size of the second fixed blade is smaller than that of the first fixed blade, and the size of the second movable blade is smaller than that of the first movable blade.
Theoretically, the more the number of the movable blades is, the better the crushing effect of the material is, but the more the number of the movable blades is, the more the number of the driving mechanisms for driving the movable blades is, the larger the volume of the equipment is, and the higher the cost is. Furthermore, at the position close to the inner wall of the chamber, the movable knife cannot be too close to the inner wall of the chamber due to the rotation of the movable knife, and the material at the position cannot be effectively crushed. Therefore, through the setting of deciding the knife tackle in this application, both the cost is reduced has also guaranteed crushing effect.
