Garbage sorting and conveying device

Abstract

The invention provides a garbage sorting and conveying device. The device comprises a rack and a conveying part, wherein the conveying part comprises a conveying belt for carrying garbage and transmission wheels for driving the conveying belt to operate, the conveying belt is tensioned on the transmission wheels and is provided with a feeding end and a discharging end, the garbage sorting and conveying device further comprises a sorting part, the sorting part comprises a material throwing mechanism and an air supply mechanism, the material throwing mechanism is arranged below the conveying belt and can act on the conveying belt to throw the garbage on the conveying belt, the air supply mechanism comprises a sealing cover covering the upper portion of the conveying belt and an air inlet pipeline arranged on the sealing cover, and the air inlet pipeline is connected with a wind power source to supply air into the sealing cover and blow the air to the garbage. According to the device, byarranging a sorting mechanism on a conveying mechanism, garbage conveying and sorting can be carried out simultaneously, through the combined action between material throwing and air supplying, the garbage of different masses generates speed differences to form different movement tracks, and therefore rapid and effective separation of the construction garbage is achieved.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, relates to the technical field of construction garbage treatment, and particularly relates to a garbage sorting and conveying device. Background technique [0002] With the acceleration of urbanization in our country, the process of urban renewal is accompanied by a large number of building demolition and demolition, resulting in a large amount of construction waste. If it is not handled properly, it will cause environmental pollution and waste of resources. The construction waste after building demolition and demolition is often mixed Decoration waste, construction waste is mostly heavy waste such as concrete blocks, crushed stones, bricks and tiles, and decoration waste is mostly light waste such as gypsum board, wallpaper, plastic, cloth art, etc. All kinds of waste are mixed together for waste disposal And reuse brings a lot of inconvenience. At present, manual sorting, water selec...

[0002] With the acceleration of urbanization in our country, the process of urban renewal is accompanied by a large number of building demolition and demolition, resulting in a large amount of construction waste. If it is not handled properly, it will cause environmental pollution and waste of resources. The construction waste after building demolition and demolition is often mixed Decoration waste, construction waste is mostly heavy waste such as concrete blocks, crushed stones, bricks and tiles, and decoration waste is mostly light waste such as gypsum board, wallpaper, plastic, cloth art, etc. All kinds of waste are mixed together for waste disposal and the inconvenience of reuse

At present, manual sorting, water selection and winnowing are mostly used for sorting construction waste. Although manual sorting is accurate, it is time-consuming and labor-intensive, with extremely low efficiency and high labor costs; water sorting is based on the density of waste. With the help of the buoyancy of water, the low-density ones float on the water surface, and the high-density ones sink into the water and are separated on the conveyor belt to achieve sorting. Although the separation effect of water separation is good, it will generate a lot of sewage, and a lot of money will be invested in the follow-up. and energy to treat the sewage, the compressed mud cake can no longer be used due to the addition of chemicals, polluting the environment and wasting resources, which violates the concept of environmental protection, and in the process of water selection, garbage with a density comparable to water will be suspended in the water , cannot be effectively separated, and some garbage of water-absorbing materials cannot be separated accurately; winnowing is to use wind force to separate light garbage and heavy garbage, and use the difference in moving speed of light garbage and heavy garbage under the action of wind to achieve separation , because after construction waste is crushed, light waste and heavy waste are mixed together, and heavy waste often hinders the movement of light waste, so the sorting effect is not ideal by relying on wind alone; and no matter Whether water separation or air separation is used, a large number of sorting equipment and conveying equipment are required to cooperate, the equipment cost and operating cost are high, and the equipment occupies a large area
