If not handled properly, it will cause environmental pollution and waste of resources. Building demolition after building demolition is often mixed. Most of the construction wastes are heavy garbage such as concrete blocks, gravel blocks, bricks and tiles, etc. The decoration wastes are mostly light wastes such as gypsum board, wallpaper, plastics, cloth, etc. All kinds of wastes are mixed together for disposal And reuse brings many inconveniences. At present, manual sorting, water sorting and air sorting 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 cost; water sorting is based on the density of materials With the help of the buoyancy of water, the low density floats on the surface of the water, and the high-density submerged conveyor belt separates it to achieve separation. Although the separation effect of water separation is good, it will produce a lot of sewage, and a large amount of capital will be required in the future. Treat the sewage with energy and energy. The compressed mud cake cannot be reused due to the addition of chemicals, causing pollution to the environment and wasting resources, which is contrary to the concept of environmental protection. In the water selection process, materials with a density equivalent to water will be suspended in the water , Can not be effectively separated, and some garbage of water-absorbing materials can not be accurately separated; air separation is the use of wind to separate light materials and heavy materials, using light materials and heavy materials to move at different speeds to achieve separation , After the construction waste is broken, light materials and heavy materials are mixed together, heavy materials often hinder light The movement of the material, so the separation is dependent on the wind alone, and the separation effect is not ideal; and whether it is water separation or air separation, a large number of separation equipment and conveying equipment are required to cooperate, and the equipment cost and operation cost are high.

The working principle of the garbage sorting and conveying device disclosed in this embodiment is that the crushed construction waste enters the sealing cover 24 from the feed bin, and falls on the feeding end of the conveyor belt 21, and the conveyor belt 21 is on the driving wheel 22 The transmission of the construction waste drives the construction waste to the discharge end; during the transportation of construction waste, the hydraulic cylinder 29 works, the piston rod 291 of the hydraulic cylinder 29 acts on the jack 27, and the jack 27 drives the roller mounting frame 26 to move up and down , So that the roller 261 moves up and down and acts on the conveyor belt 21 to throw up the garbage on the conveyor belt 21. During the throwing and falling process, the garbage will get a preliminary separation due to the different mass gravity, the falling speed and the moving trajectory. , The garbage will be thrown up many times during the whole transportation process. When the garbage reaches the built-in fan 251 near the discharge end, all kinds of garbage are already in a preliminary separation state, and will not be mixed together, there is a gap between various garbage In the loose state, the two sides of the conveyor belt 21 are built in to simultaneously supply wind to the garbage in a preliminary separation and dispersion state. Different garbage will have different speeds under the action of wind due to different masses. Different movement trajectories are formed, and the air inlet duct 25 is installed obliquely on the sealing cover 24. When the garbage is subjected to wind, it not only receives an upward force, but also a forward traveling force. The air inlet duct 25 is located near the discharge end. The wind state continues until discharge, and the garbage is subjected to the combined action of throwing and wind blowing during the transportation process. When the garbage falls from the discharge port, different trajectories are formed due to the difference in quality to achieve separation, transportation, throwing and feeding The wind is carried out in the sealed cover 24, and the garbage is restrained in the sealed cover 24, to avoid the garbage thrown up and scattered around after the wind, reduce the dust pollution and noise pollution and improve the wind effect; when the garbage falls from the discharge port again The wind is blown by the external fan 5, so the sorting effect is better; the partition 32 of the aggregate device 3 is adjusted to a suitable position according to the discharge path of the garbage, so that the sorted garbage can accurately fall into the designated collection In the material area, to avoid the separation of the garbage after the material is mixed again.
