Material sedimentation hopper with physical defoaming device

Abstract

The invention relates to the technical field of sedimentation of impurities in water, in particular to a material sedimentation hopper with a physical defoaming device, which is characterized in that a hollow position is arranged in the middle of a support, a plurality of groups of overflow hoppers are arranged from a first end to a second end along the length direction of the hollow position, and the plurality of groups of overflow hoppers are sequentially arranged at equal height; the top of the overflow hopper is in sealed connection with the periphery of the hollow position, an overflow baffle surrounds the periphery of the top of the hollow position and extends upwards, water flows from the first end of the hollow position to the second end of the hollow position, a sedimentation type water inlet device is arranged at the first end of the hollow position, and a defoaming roller assembly and a water spraying defoaming assembly are installed on a side wall baffle assembly. The defoaming roller assembly and the water spraying defoaming assembly are used for conducting defoaming treatment on foam on the surface of a water body in a physical defoaming mode. The sedimentation hopper can be used for carrying out sedimentation treatment on particle materials in a water body, and meanwhile, bubbles generated in the material moving process are eliminated, so that environmental pollution caused in the production process is avoided.

Description

technical field [0001] The invention relates to the technical field of sedimentation of impurities in water, in particular to a material sedimentation bucket with a physical defoaming device. Background technique [0002] The traditional slag treatment adopts the form of pool sedimentation and filter press to separate materials. The components of materials are circulating water and 0-2mm fine sediment. The sedimentation method of the pool divides the material particle size into two specifications: 0-0.1mm and 0.1-2mm. The 0.1-2mm fine sand settles at the bottom of the pool and is salvaged by a hydraulic grab; the 0-0.1mm mud-water mixture is filtered through a filter press to separate the sand from water; the 0.1-2mm fine sand is used as the raw material for making environmentally friendly bricks, Sediment within 0.1mm is used for road paving. [0003] Due to the large proportion of silt and sand in the 0-2mm material, it is necessary to clean and salvage the 0.1-2mm fine ...

Problems solved by technology

[0003] Due to the large proportion of mud and sand in the 0-2mm material, it is necessary to clean and salvage the 0.1-2mm fine sand from time to time in the way of sedimentation in the pool, which is time-consuming and laborious, and the efficiency is low

During the movement of the material, due to the excessive flow rate of the material, too much air is brought into the material, and the air and the water in the material mix to generate air bubbles, resulting in the accumulation of too many air bubbles and overflowing water to affect the surrounding environment.
