Description

Technical Field

[0001] The utility model belongs to the technical field of water flotation machines, and particularly relates to a sewage discharge and anti-blocking structure for a light material water flotation machine. Background Art

[0002] The light material water flotation machine uses water flotation technology to screen and classify materials with different densities in garbage. The materials with different densities in the garbage have different buoyancies in water, enabling the materials in the garbage to be stratified during the process of falling materials, and separating the materials with different densities through different collection means. This equipment has the characteristics of compact structure, small floor area for installation and use, recycling of the sorting medium water circulation, less sewage discharge, no dust, good sorting effect, high efficiency, etc.; it is mainly used in the production line for construction waste treatment.

[0003] After the construction waste entering the water tank of the light material water flotation machine undergoes water washing and separation treatment, the construction aggregates and light materials are separated and transported out respectively, and enter the next process for treatment; the fine substances such as soil and sediment in the construction waste are mixed with the water in the water tank to form sewage. Due to the different specific gravities of various fine substances in the sewage, the fine substances with a specific gravity greater than that of water settle to the bottom of the water tank, precipitate and accumulate. With the long-term operation of the equipment, the accumulated fine substances will become more and more. These accumulated fine substances occupy the capacity of the water tank, reducing the water storage in the water tank, seriously affecting the stratification of the construction waste in the water in the water tank during the process of falling materials, thus reducing the sorting efficiency of the equipment, and the sorting effect gradually deteriorates. Therefore, it is necessary to clean and discharge these accumulated fine substances.

[0004] Although the existing light material water flotation machines on the market are all provided with sewage discharge devices for cleaning and discharging such accumulated fine substances, due to the unreasonable design of the device structure and the deficiency in configuration, the sewage discharge operation is difficult and the sewage discharge is not smooth, seriously affecting the equipment output and the operation rate of the entire construction waste treatment operation production line.
