Waste sorting and conveying equipment

Abstract

The invention provides waste sorting and conveying equipment. The equipment comprises a feed bin, a sorting and conveying device, a collecting device and a rack. The sorting and conveying device comprises a conveying portion and a sorting portion. The conveying portion comprises a conveying belt used for carrying waste and driving wheels used for driving the conveying belt to operate. The feed binis arranged above the feed end. The collecting device is close to the discharging end and located below the discharging end. The sorting portion comprises a throwing mechanism and a wind supply mechanism. The throwing mechanism is arranged under the conveying belt, and can act on the conveying belt so that the waste on the conveying belt can be thrown upwards. The wind supply mechanism comprisesa sealing hood covering the upper portion of the conveying belt, and wind inlet pipelines which are arranged on the sealing hood. The wind inlet pipelines are connected with a wind source and supply wind into the sealing hood so that the wind can be blown towards the waste. According to the waste sorting and conveying equipment, through throwing and wind blowing, materials with different masses are made to have speed differences in the conveying process, so that different moving trajectories are formed, and accordingly, the materials are effectively separated at the discharging end.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, relates to the technical field of construction garbage treatment, and in particular relates to garbage sorting and conveying equipment. 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.

[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 materials. 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. The compressed mud cake can no longer be used due to the addition of chemicals, which will pollute the environment and waste resources, which violates the concept of environmental protection. In addition, during the water selection process, materials with the same density as 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 materials and heavy materials, and use light materials and heavy materials to move at different speeds under the action of wind to achieve separation , because light materials and heavy materials are mixed together after the construction waste is crushed, and heavy materials often hinder the movement of light materials, so the separation 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 floor area is large.
