Description
Technical Field
The invention relates to a kitchen waste treatment device, in particular to a kitchen waste sand removal device.
Background
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:
1. and (3) fertilizer treatment: the fertilizer treatment of the kitchen waste mainly comprises two kinds of treatment of aerobic composting and biogas slurry after anaerobic biogas preparation, and the composting and the biogas slurry are prepared into fertilizer.
2. And (3) feed conversion treatment: the fodder treatment of kitchen waste is to utilize a large amount of organic matters contained in the kitchen waste, and convert the kitchen waste into high-calorie animal fodder after crushing, dehydrating, fermenting and drying the kitchen waste.
3. And (3) energy 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 removing impurities from the kitchen waste, fermenting the organic material to prepare alcohol.
In view of the above, the method comprises the step of pretreating kitchen waste. Because kitchen waste is wide in source and complex in components, the concentrated treatment process of the kitchen waste contains more or less heavy impurities such as gravel, metal, ceramic, glass and bones which are unfavorable for subsequent treatment, and the impurities are required to be separated from the kitchen waste in order to be favorable for subsequent treatment.
Disclosure of Invention
In view of the above, the invention aims to overcome the defects of the prior art and provide a separating device capable of effectively separating heavy impurities such as metal, gravel, ceramics, glass, bones and the like from kitchen waste.
In order to solve the technical problems, the invention adopts the following scheme:
the utility model provides a kitchen garbage sand removal 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 size of holding chamber is greater than horizontal size is collected to impurity, and is equipped with the bin outlet. 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.
The sand setting device feeding port is arranged at the top of the sand setting device, and the sand setting device feeding port is provided with a material crusher. The kitchen waste is wide in source and different in size, is crushed firstly, and then is separated from impurities, so that the separation effect is better. The crushed materials directly enter the sand setting device without secondary carrying, and the efficiency is higher.
The material crusher comprises a feed inlet and a discharge outlet; the material crusher comprises an upper chamber and a lower chamber which are mutually communicated, a first crushing mechanism is arranged in the upper chamber, a second crushing mechanism is arranged in the lower chamber, and the blade size of the first crushing mechanism is larger than that of the second crushing mechanism, so that the size of a material crushed by the first crushing mechanism is larger than that of a material crushed by the second crushing mechanism; the material grinder feeding port is arranged on the upper chamber, and the material grinder discharging port is arranged on the lower chamber; the material crusher discharge port is communicated with the sand setting device feed port.

The upper chamber and the lower chamber are relatively, the first crushing mechanism is arranged as an upper chamber, and the second crushing mechanism is arranged as a lower chamber. The term "the size of the blades of the first comminution mechanism is larger than the size of the blades of the second comminution mechanism" is understood here to mean that the material comminuted by the first comminution mechanism is larger than the material comminuted by the second comminution mechanism.
Because this application adopts twice crushing step, in order to be convenient for pass through the second crushing smoothly of the material after the first crushing. The upper chamber and the lower chamber are vertically communicated, the first crushing mechanism is arranged at a position close to the feeding hole of the upper chamber, and the second crushing mechanism is arranged at a position close to the discharging hole of the lower chamber. The materials after first crushing can directly fall onto the second crushing mechanism under the action of gravity, so that the resistance of the movement of the materials is reduced, and the energy consumption of material transportation is also reduced.

Theoretically, the larger the number of moving blades is, the better the crushing effect of the materials is, but the larger the number of moving blades is, the larger the number of driving mechanisms for driving the moving blades is, the larger the size of the equipment is, and the higher the cost is. Furthermore, at a position close to the inner wall of the chamber, the moving blade cannot be too close to the inner wall of the chamber due to the rotation of the moving blade, and the material at the position cannot be effectively crushed. Therefore, through the setting of fixed knife group in this application, both the cost is reduced, has also guaranteed crushing effect.
