Detailed Description

The invention will be further described with reference to the accompanying drawings, which are provided for illustration of specific embodiments of the invention and are not to be construed as in any way limiting the invention, as follows:

example 1

As shown in fig. 1, the novel electromagnetic flotation machine comprises a driving device 1, a frame 2, a tank body 3, a foam scraping device 6, a stirring device 7 and an air inlet device 8. The tank body 3 is made of iron-carbon alloy, is fixed on the frame 2 and is provided with a cavity for storing slurry. The stirring device 7 is rotatably fixed to the frame 2 by means of bearings and bearing blocks (not shown). The stirring device 7 is provided with a stirring head 701, and the stirring head 701 extends into the tank body 3 to stir the slurry in the tank body 3. The air inlet device 8 is provided with an air duct (not shown in the figure) extending into the cavity of the tank body 3, and air is pumped into the slurry in the tank body 3 by an air compressor. The foam scraping device 6 comprises a scraping plate 601, wherein the scraping plate 601 is arranged in a tangent mode with the liquid level of the tank body 3, is rotationally fixed on the rack 2 and is used for scraping foam on the upper surface of the tank body 3. The fixed hook 5 is an L-shaped structure and is fixed on the outer wall of the groove body 3, the layers are arranged, the electromagnetic coil 4 is arranged in the fixed hook 5 and spirally wound outside the groove body 3 and is electrically connected with an external power supply. Adjacent electromagnetic coils 4 have a certain gap therebetween. The electromagnetic coil 4 interacts with the tank body 3 after being electrified, and can generate electromagnetic attraction force to attract iron powder in slurry of the tank body 3.

In some embodiments, the tank body 3 is made of soft iron or silicon steel, and after the electromagnetic coil 4 is powered off, residual electromagnetic attraction does not exist inside the tank body 3, so that iron powder in the tank body 3 can move freely when the electromagnetic coil 4 is powered off. The soft iron or silicon steel material is the conventional material, and is not described herein again.

The working principle is as follows:

after solenoid 4 circular telegram, produce electromagnetic attraction with cell body 3 interact, electromagnetic attraction can attract the iron powder in the cell body 3, before iron powder combines with the silicon selection collecting agent or before the foam that is mingled with a large amount of iron powder is scraped out the flotation device, utilize electromagnetic attraction to produce the reverse action to the combination of iron powder and silicon selection collecting agent, reduce the combining capacity of iron powder and silicon selection collecting agent, and then reduce the loss at the in-process iron powder of silicon removal.

Example 2

As shown in fig. 2 and 3, the structure of a novel electromagnetic flotation machine is the same as that of example 1, except that:

the outer side wall surface of the tank body 3 is fixed with a plurality of electromagnetic generating mechanisms 9, and a certain distance is reserved between every two adjacent electromagnetic generating mechanisms 9. The fixing form of the electromagnetic generating mechanism 9 and the groove body 3 can be welding, colloid bonding, riveting, bolt or screw fixing connection and the like. The electromagnetic generating mechanism 9 includes a coil 901, a fixing frame 902, and a fixing base 903. The coil 901 is spirally wound on the fixing frame 901 and electrically connected with an external power supply. The holder 902 is made of soft iron or silicon steel. The coil 901 interacts with the fixing frame 902 after being electrified, and can generate electromagnetic attraction force. The single electromagnetic generating mechanism 9 is independently connected with an external power supply, the number of the electrified electromagnetic generating mechanisms 9 can be selected according to actual production requirements, and then the corresponding electromagnetic attraction is controlled. The electromagnetic generating mechanism 9 is arranged on the tank body 3 and can independently generate electromagnetic attraction, so that the material of the tank body 3 only needs to be adapted to the characteristics of slurry, the material selection difficulty is reduced, and the production cost of equipment is reduced.

Thus, it should be understood by those skilled in the art that while exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations and modifications can be made in accordance with the principles of the invention without departing from the spirit and scope of the invention, which is broadly defined and defined herein.
