[0046] The inner wall of the circular box 701 is symmetrically provided with two first arc-shaped conductive strips 708, and the inner wall of the circular box 701 is symmetrically provided with two second arc-shaped conductive strips 709; the two first arc-shaped conductive strips 708 and the two second arc-shaped conductive strips 709 are staggered; insulating pads are arranged between the two ends of the adjacent first arc-shaped conductive strips 708 and the second arc-shaped conductive strips 709; four power connection sockets 710 are arranged at equal angles on the outer side of the circular box 701; the four power connection sockets 710 are electrically connected with the two first arc-shaped conductive strips 708 and the two second arc-shaped conductive strips 709 respectively; a first power supply is electrically connected between the two first arc-shaped conductive strips 708; a second power supply is electrically connected between the two second arc-shaped conductive strips 709; two contacts 707 are symmetrically arranged on the rotating block 703; wires are electrically connected between the two contacts 707; the two first arc-shaped conductive strips 708, the first power supply and the two electromagnets 706 form a first series circuit; the two second arc-shaped conductive strips 709, the second power supply and the two electromagnets 706 form a second series circuit; the current flow directions of the two series circuits are opposite; during the rotation of the rotating block 703, the electromagnets 706 are intermittently connected to the positive and negative currents through the contacts 707, the first arc-shaped conductive strips 708 and the second arc-shaped conductive strips 709, so as to drive the push piston 5101 to move up and down reciprocatingly, realize the feeding of the flocculant and aeration, and when the electromagnets 706 generate force on the magnetic blocks 5103, the push piston 5101 can rotate by a certain angle, the positions of the first through grooves 604 and the second through grooves 606 are adjusted, and the subsequent addition of the flocculant is facilitated.

[0047] Working principle: when working, first, open the switch valve on the feeding pipe 3, put the natural alkali crude halite that needs to be deeply purified into the mixing cylinder 1, then close the switch valve, in the original state, the two magnetic blocks 5103 at the bottom end of the push piston 5101 are distributed in a square four-corner mode with the two electromagnets 706, the two first through grooves 604 of the fixed plate 603 are staggered with the two second through grooves 606 on the rotating plate 605, so that the feeding pipe 601 is closed, at this time, the flocculant solution for deeply purifying the natural alkali crude halite is filled into the inside of the storage cylinder 602;

[0048] then, connect the power, connect the two power connection sockets 710 electrically connected with the two first arc-shaped conductive strips 708 into the first circuit, and connect the two power connection sockets 710 electrically connected with the two second arc-shaped conductive strips 709 into the second circuit, then start the driving motor 705, so that the output shaft of the driving motor 705 drives the rotating block 703 to rotate;

[0049] In the process of rotating the rotating block 703, the contact points 707 rotate synchronously with the rotating block 703, and when the two contact points 707 are in contact with the two first arc-shaped conductive strips 708 respectively, at this time the two electromagnets 706 are connected to the forward current, so that the electromagnets 706 generate magnetic force opposite to the magnetic block 5103, so that the electromagnets 706 generate attractive force to the magnetic block 5103, under the action of the attractive force, first push the piston 5101 to rotate under the action of the attractive force, so that the two magnetic blocks 5103 move to the upper of the two electromagnets 706 respectively, and make the push piston 5101 move downward;

[0050] After the push piston 5101 rotates, since the push piston 5101 is connected with the guide rod 607 at the bottom end of the rotating plate 605 through the guide groove 5102, so as to drive the rotating plate 605 to rotate, so that the second through groove 606 on the rotating plate 605 corresponds to the first through groove 604 on the fixed plate 603, at this time, with the downward movement of the push piston 5101, part of the flocculating agent solution is sucked into the space above the push piston 5101 in the rotating pipe 501;

[0051] At the same time, since the third one-way valve 509 connected with the air inlet groove 508 is responsible for the air outside the rotating pipe 501, and the second one-way valve 507 on the lower horizontal pipe 506 is responsible for the air inside the rotating pipe 501 to enter the mixing cylinder 1, and the liquid in the mixing cylinder 1 cannot enter the lower horizontal pipe 506, so that in the process of moving the push piston 5101 downward, the air in the rotating pipe 501 is pressed to enter the natural alkali brine from the second one-way valve 507;

[0052] When the rotating block 703 rotates to the position where the two contact points 707 are in contact with the two second arc-shaped conductive strips 709 respectively, the electromagnets 706 are connected to the second circuit, so that the electromagnets 706 are connected to the reverse current, so that the electromagnets 706 generate the same magnetic force as the magnetic block 5103, so that the electromagnets 706 generate repulsive force to the magnetic block 5103, under the action of the repulsive force, the push piston 5101 rotates again, driving the rotating plate 605 to rotate to the position where the second through groove 606 is deviated from the first through groove 604, at this time, the two magnetic blocks 5103 and the two electromagnets 706 are in the square four-corner position;

[0053] At this time, the push piston 5101 moves upward along the rotating pipe 501 under the action of the repulsive force, so as to suck the air outside the rotating pipe 501 from the third one-way valve 509, and at the same time, the flocculating agent solution above the push piston 5101 is squeezed into the natural alkali brine from the first one-way valve 505, wherein the first one-way valve 505 is responsible for connecting the flocculating agent solution into the natural alkali brine, and preventing the natural alkali brine from entering the upper horizontal pipe 504;

[0054] In summary, with the rotation of the rotating block 703, the push piston 5101 moves longitudinally reciprocating inside the rotating tube 501, during the upward movement of the push piston 5101, the flocculating agent solution is squeezed into the trona brine, and air is sucked in, during the downward movement of the push piston 5101, air is introduced into the mixed solution of the flocculating agent solution and the trona brine, to realize aeration, while sucking in the subsequent introduced flocculating agent solution, at the same time, the connecting shaft 704 at the top of the rotating block 703 is bolted and fixedly connected with the bottom shaft 503 at the bottom end of the rotating tube 501, so as to drive the rotating tube 501 to rotate continuously, so that the stirring blade 502 can continuously stir the mixed solution of the flocculating agent solution and the trona brine;

[0055] After the continuous introduction of the flocculating agent solution, so that the flocculating agent solution and the trona brine are uniformly mixed, the switch valve on the discharge pipe 4 is opened, the mixed solution inside the mixing cylinder 1 is discharged into the static tank 2, and the mixed solution is statically placed in the static tank 2, so that the impurities in the trona brine are settled, and the deep purification is completed.
