Grading screening and storing device for industrial waste residue harmless treatment

Abstract

The invention discloses a grading screening and storing device for industrial waste residue harmless treatment. The grading screening and storing device comprises a storage bin, a screening bin, a coarse screen and an overturning rod. The overturning rod is driven by a drive assembly to rotate, the coarse screen is overturned, and floating objects filtered and left on the coarse screen are pouredinto a collecting device. A fine screen is arranged in the screening bin and driven by a high-frequency vibration assembly to vibrate up and down at high frequency. A discharging port is formed in thestorage bin. The grading screening and storing device has the beneficial effects that the coarse screen and the fine screen are arranged and can be used for screening and filtering the floating objects and fine particles in industrial waste residues respectively; meanwhile, the coarse screen is driven by the drive assembly to overturn, the floating objects left in the coarse screen after filtering can be poured out, and the labor intensity of workers is lowered; and the high-frequency vibration assembly is used for driving the fine screen to vibrate up and down at high frequency, accordingly,the fine screen can filter the fine particles well, and the situation that the fine particles block the fine screen, and the filtering efficiency of the fine screen is influenced is avoided.

Description

technical field [0001] The invention relates to the field of solid pollutant treatment devices, in particular to a classification, screening and storage device for harmless treatment of industrial waste residues. Background technique [0002] Industrial waste refers to the toxic, flammable, corrosive, infectious, chemically reactive and other harmful solid waste discharged in industrial production. The long-term storage of solid waste of industrial waste is not only Occupy a large amount of land, and will cause serious pollution and harm to the water system and the atmosphere. As a result of the accumulation of large amounts of mining waste rock, large tracts of farmland and forest areas have been destroyed. Hazardous industrial slag has been stored for a long time, and after being leached by rain and snow, the soluble components seep down from the surface with water. Migrating and transforming to the soil, enriching harmful substances, acidifying, alkalizing and hardening...

Problems solved by technology

For example: when coal gangue piled up like a mountain spontaneously ignites, the fire spreads and it is difficult to rescue. And release a large amount of SO2 gas, which pollutes the environment. In addition, the smoke and harmful gases discharged when the incineration method is used to dispose of solid waste will also pollute the atmosphere.

[0003] When industrial waste is processed, it is usually necessary to screen the industrial waste to filter the floating objects (or larger objects) and fine particles. The efficiency is low, and at the same time, workers need to manually pour out the floating objects to avoid blocking the processing equipment. This method leads to high labor intensity for workers and affects the overall efficiency of harmless treatment.
