[0023] As Figures 1-3 Indicated, a kind of flotation device of adjusting ore pulp temperature, including flotation machine body 1, the base 2 is fixed in the box of flotation machine body 1, the base 2 is four and is located at the four corners of box respectively, base 2 is hollow structure, several mutually parallel electric heating rods 3 are installed in base 2, the thickness of the top of hollow structure is not greater than the diameter of electric heating rod 3 five one sixth, a support plate 4 is arranged between adjacent electric heating rod 3, support plate 4 is welded in hollow structure, wire tube 5 is welded on base 2, wire tube 5 is communicated with base 2, wire tube 5 is used to accommodate the wire of electric heating rod 3, through the electric heating rod 3 in base 2 to heat ore pulp, to avoid the problem that heat loss exists when using hot water heating, leading to energy utilization rate reduction, while the thin top of hollow structure is heated ore pulp at the same time, avoid the corrosion of electric heating rod 3 to ore pulp, while support plate 4 reinforces thin top, avoid the deformation of thin top caused by water pressure.

[0024] In the embodiment, as Figure 2 Indicated, the top of base 2 is arc surface, arc surface faces away from the bottom corner of box, in the stirring process of ore pulp, the bottom of traditional flotation cell is right angle structure, slurry gas mixture is not easy to form ore pulp flow area when impacting on the bottom of box, more likely to form calm area, mineral is prone to deposit in corner and lead to insufficient flotation, while ore pulp impacts on the arc top panel of bottom corner of box, can generate an ore pulp flow area on the arc top panel, mineral is not easy to settle in the flow area, thereby enhancing the fluidity of ore pulp, effectively avoid the problem of existing flotation dead angle of flotation machine, so that mineral flotation is more sufficient.

[0025] In the embodiment, as Figure 2 And 4 Indicated, the stirring shaft of flotation machine body 1 is hollow structure, air inlet hole 6 and air outlet hole 7 are set apart on stirring shaft, air inlet hole 6 is close to the top of box, blade 8 is also welded on stirring shaft, cavity is arranged in blade 8, air outlet hole 7 is used to connect stirring shaft and blade 8, exhaust hole 9 is set on the cavity wall of blade 8, while discharging air bubble, through stirring to make air bubble dispersion, so that air bubble can be evenly and suitably dispersed in ore pulp, thereby can effectively improve flotation efficiency.

[0026] In the embodiment, as shown in Figure 2 and 4 The blade 8 is helical, and the exhaust hole 9 is located on the back of the blade 8 in the rotating direction. The helical blade 8 forms a liquid flow in the ore pulp when rotating. The ore pulp on the stirring shaft is thrown out of the stirring center area by the blade 8 under the action of centrifugal force. The thrown ore pulp flow hits the flotation tank wall and then forms an upflow and a downflow, respectively. The circulation of the ore pulp in the flotation tank is enhanced under the driving of the upflow and the downflow. This also makes the bubbles more easily subdivided and dispersed in the entire flotation tank during the hitting process, so that the bubbles contact more mineral particles and form more mineralized bubbles, thereby improving the flotation effect.

[0027] In the embodiment, as shown in Figure 2 The end face of the blade 8 away from the stirring shaft is an arc face, and the arc top of the arc face is away from the stirring shaft. This can reduce the hindering effect of the ore pulp on the blade 8, thereby reducing the load of the stirring part and saving the power consumption.
