Problems solved by technology

Due to the small specific gravity and high viscosity of the foam and the small slope of the launder, the fluidity of the foam is very poor, which seriously affects the flotation efficiency
Nowadays, the method of spraying water is generally used to eliminate foam in production. This method not only consumes a lot of water resources, but also affects the next process, reduces the concentration of ore pulp, and causes a decrease in the concentration of chemicals.

Embodiment

[0015] In an iron ore reverse flotation process, the cross-section of the tailings (foam) chute is 800mm×800mm. Due to the small slope of the chute and the high viscosity of the foam, the fluidity of the foam is poor, and foam often overflows from the chute. For this reason, we have designed a group of three flotation foam defoaming equipment, which are installed at intervals of 5m. Considering the large proportion of liquid in the lower layer, the possibility that the upper layer may not be full, and the geometric dimensions of the chute, the distance between the upper horizontal defoaming rod and the upper edge of the chute is designed. The length of the horizontal defoaming rod is 200mm, the length of the horizontal defoaming rod is 600mm, the distance between the lower horizontal defoaming rod and the bottom of the chute is 300mm, the length of the horizontal defoaming rod is 400mm, the distance between the middle horizontal defoaming rod and the upper and lower horizontal d...

Abstract

The invention relates to the field of flotation technology, in particular to a flotation foam defoaming device, which consists of a motor, a reducer connected to the output shaft of the motor and an integrated defoaming rod connected to the output shaft of the reducer. The integrated defoaming rod body is composed of a vertical main shaft and 2-5 layers of horizontal defoaming rods evenly distributed along the axial direction connected to the vertical main shaft. The length of the rod is the shortest, and the horizontal defoaming rods of each layer are staggered from each other in the horizontal direction. According to the properties of the foam and the geometric design of the foam chute, considering that the volume of the upper foam is larger and the liquid is less, the volume of the foam in the lower part of the foam layer is smaller and the liquid is more, the length of the defoaming rod is as long as the upper layer and the lower layer short. The material is stainless steel. The beneficial effect of the present invention is that: due to the adoption of the above equipment, the foam is efficiently eliminated, the conveying efficiency is improved, and the tailings conveying and tailings re-election of the reverse flotation are beneficial.

Description

technical field [0001] The invention relates to the technical field of flotation, in particular to a flotation foam defoaming device. Background technique [0002] In the production process of flotation process, both positive and reverse flotation must rely on the generated foam to separate minerals. Due to the small specific gravity and high viscosity of the foam and the small slope of the launder, the fluidity of the foam is very poor, which seriously affects the flotation efficiency. Nowadays, the method of spraying water is generally used to eliminate foam in production. This method not only consumes a large amount of water resources, but also affects the next process, reduces the concentration of ore pulp, and causes a reduction in the concentration of chemicals. Contents of the invention [0003] The purpose of the present invention is to provide a flotation foam defoaming device with high efficiency, no pollution and no influence on the next process, which is benef...
