Embodiment Construction
[0027] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0028] Such as figure 1 , 2 The novel shallow groove double impeller flotation machine of the present invention shown in 3 is mainly formed by a plurality of tank bodies 1 connected in series, each tank is communicated by a middle ore box, and the center of the tank body is provided with a double impeller stirring mechanism, The bubble scraping mechanism is arranged on both sides of the double impeller stirring mechanism, above the liquid level of the tank.
[0029] 1. Tank body
[0030] The tank body is a rectangular section, such as Figure 4 , 5 As shown in , 6, it has the advantage of sufficient volume, providing enough space for the collision and adhesion of ore particles and air bubbles.
[0031] There are 45° bevels on both sides of the tank body, which is conducive to the accumulation of coarse ore particles to the stirring area in the...

The invention relates to the field of coal flotation equipment, in particular to a novel shallow-trough double-impeller flotation machine which solves the problems of insufficient single-machine handling capacity, poor flotation efficiency and large production line infrastructure input of a mechanical stirring flotation machine due to trough body capacity limitation. The novel shallow-trough double-impeller flotation machine comprises trough bodies, stirring mechanisms, flow stabilizing plates with false bottoms and bubble scraping mechanisms, each stirring mechanism comprises a stirring shaft, a stirring impeller is fixed on each stirring shaft, split stators are arranged on the periphery of each stirring impeller, each stirring impeller and the stators are positioned on the upper side of the center of each flow stabilizing plate with the false bottom, each stirring impeller is fixed in the middle of the corresponding stirring shaft, an impulse impeller is fixed at the bottom end of each stirring shaft and positioned on the lower side of the center of each flow stabilizing plate with the false bottom, and flow guide cylinders are arranged on the periphery of each impulse impeller. The novel shallow-trough double-impeller flotation machine provides a novel ore pulp feeding mode to enable ore pulp in troughs to be circulated more smoothly, power consumption and chemical consumption are reduced, and efficient separation and recovery of floating mineral grains are achieved.
Description
technical field [0001] The invention relates to the field of coal flotation equipment, in particular to a novel shallow groove double impeller flotation machine. Background technique [0002] Flotation is the main method for sorting fine-grained minerals. Almost all minerals can be separated from ores by flotation. At the same time, it can process secondary resources and non-mineral resources. [0003] Large-scale coal preparation plants, large-scale equipment, and simplified processes are the inevitable trends in the development of my country's coal preparation industry. Although flotation machines have made some progress in large-scale in recent years, the maximum processing capacity of a single machine can only meet the requirements of 300t / h raw coal selection capacity (equivalent to 1.5 million t / a coal preparation plant). According to the average scale of raw coal processing capacity of 800t / h in developed countries, the volume of a single tank of the flotation machin...
