Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a novel ore dressing flotation machine of splashproof ore deposit, including box 1, the solid fixed ring of fixedly connected with on the roof in box 1, gu fixed ring's inner wall rotates through the bearing and installs gas collection fill 4, be provided with air inlet mechanism in the gas collection fill 4, terminal surface middle part is connected with (mixing) shaft 6 under the gas collection fill 4, even level is provided with a plurality of stirred tubular 8 on the (mixing) shaft 6, the vertical mounting groove of having seted up on the (mixing) shaft 6, and the inner chamber of a plurality of stirred tubular 8 all communicates with the mounting groove, be provided with aeration mechanism in the mounting groove, the liquid outlet has been seted up to.

In the utility model, the air inlet mechanism comprises a driving motor 2 arranged on a box body 1, an output shaft of the driving motor 2 extends into an air collecting hopper 4 and is evenly connected with a plurality of fan blades 5, one end of each fan blade 5 far away from the output shaft of the driving motor 2 is welded with the inner wall of the air collecting hopper 4, a plurality of air vents 9 are evenly arranged on the upper end surface of the box body 1, the air vents 9 are all positioned above the air collecting hopper 4, the aeration mechanism comprises a communicating pipe 7 arranged in a mounting groove of a stirring shaft 6, the upper end of the communicating pipe 7 is communicated with the air collecting hopper 4, a piston block 12 is connected between the communicating pipe 7 and the groove wall of the mounting groove in a sliding way, the density of the piston block 12 is slightly smaller than that of ore pulp, so that the piston block 12 can freely float up, one side of the rotating advancing direction of the stirring pipe 8 is connected with a flow distribution plate 11 which is horizontally arranged, and one side of the, the plurality of air outlets 10 are communicated with the inner cavity of the stirring pipe 8;

be provided with feed inlet 13 and discharging pipe 14 on box 1 respectively, the inner diapire that is higher than the liquid outlet of feed inlet 13, be provided with the control valve on the discharging pipe 14, scrape material mechanism and rotate the material roller 15 of scraping of installation through the dead lever on box 1, the input of scraping material roller 15 is connected with external input device, be provided with out bubble mouth 3 through the swash plate on the box 1, scrape and radially be connected with a plurality of flitchs of scraping on the material roller 15, scrape the material roller 15 through the pivoted and can scrape the bubble in the play bubble mouth 3 and leave out bubble mouth 3.

When the utility model is used, a user pours ore pulp into the box body 1 from the feed inlet 13, the driving motor 2 is started, the driving motor 2 drives the fan blade 5 to rotate, the air above the box body 1 can be sucked into the gas collecting hopper 4 through the air holes 9 in the rotating process of the fan blade 5, then the air forms downward air flow to enter the communicating pipe 7, the air flow flows into the stirring pipe 8 from the mounting groove of the stirring shaft 6, so that the air pressure in the stirring pipe 8 is higher than the external liquid air pressure, the gas in the stirring pipe 8 is dissipated into the ore pulp through the air outlet 10, meanwhile, because the fan blade 5 is fixedly connected with the gas collecting hopper 4, the stirring shaft 6 is fixedly connected with the gas collecting hopper 4, along with the rotation of the fan blade 5, the stirring pipe 8 rotates along with the rotation, the ore pulp is stirred, bubbles sprayed by the stirring pipe 8 are more uniform with the ore pulp, and then ore particles in the ore pulp are more easily attached to, when the ore particles in the ore pulp float to the liquid level, the input device of the scraping roller 15 is started, the scraping roller 15 drives the plurality of scraping plates to rotate, and therefore the bubbles at the bubble outlet 3 are continuously scraped away from the box body to collect the ore particles;

when the device is used, when the ore pulp in the box body 1 is not enough to completely submerge all the stirring pipes 8, the piston block 12 naturally falls under the action of gravity, a channel between the stirring pipe 8 above the liquid level and the stirring shaft 6 is blocked, and airflow is prevented from flowing out of the stirring pipe 8 above the liquid level, so that the device can automatically adjust the height of an air inlet pipeline when the ore pulp in the box body 1 is less, so that the ore pulp has a better bubble generation effect, and the escape of gas is reduced;

it is worth noting, through be provided with flow distribution plate 11 and venthole 10 respectively in the both sides of agitator pipe 8, when agitator pipe 8 carries out rotary motion, flow distribution plate 11 can separate the resistance that reduces the ore pulp with the ore pulp, make agitator pipe 8 can rotate fast, and agitator pipe 8 produces the empty effect of exploding easily at the fast rotation in-process, the surface of a back of water of agitator pipe 8 can produce local vacuum promptly, and venthole 10 is just to the empty position of exploding, make the air in agitator pipe 8 can be taken out fast, make the effect of empty explosion produce the stack like this, improve the device's play bubble efficiency greatly, make the device's play bubble effect better, and the bubble is less, also must not break when the bubble floats to the liquid level, thereby the flotation efficiency of ore granule has been improved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
