Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1 and Fig. 2, a kind of easy cleaning high gradient electromagnetic separator, frame 1 is provided with track 13 and coil 10 above.Coil 10 is formed by copper pipe coiling, is filled with cooling water in copper pipe, can cool like this to coil 10.Coil 10 is positioned at above track 13.Left magnetic pole head 11 and right magnetic pole head 12 lay respectively at the center of coil 10 inside, and the outside of left magnetic pole head 11 is all connected with track 13 with the outside of right magnetic pole head 12.Deironing chamber 9 is between left magnetic pole head 11 and right magnetic pole head 12 and be positioned at coil 10 and be provided with.Magnetic Jie net 15 is provided with in deironing chamber 9.The bottom in deironing chamber 9 is provided with feeding device 5, feeding back device 14 and slag-draining device 6, and the top in deironing chamber 9 is provided with drawing mechanism 8 and charge valve 16.Feeding device 5 comprises feeding pipe and pan feeding valve, and feeding back device 14 comprises feed back pipe and material returning valve, and slag-draining device 6 comprises scum pipe and residual cake valve, and drawing mechanism 8 comprises discharge nozzle and outlet valve.
For the ease of cleaning residue, the present embodiment also comprises cleaning device.This cleaning device comprises water tank 2, water pump 3, lower water inlet pipe 4 and upper water inlet pipe 7.Water tank 2 and water pump 3 are all positioned at the bottom of frame 1.Water tank 2 is connected with water pump 3 by water-supply-pipe.Water pump 3 is also connected with lower water inlet pipe 4 and upper water inlet pipe 7, and lower water inlet pipe 7 is communicated with the bottom in deironing chamber 9, and upper water inlet pipe 7 is communicated with the top in deironing chamber 9.
The operation principle of the present embodiment:
When coil 10 switches on power, the magnetic line of force forms a loop by left magnetic pole head 11, deironing chamber 9, right magnetic pole head 12 with track 13.Production background magnetic field in deironing chamber 9, thus magnetize the magnetic Jie net 15 be placed in deironing chamber 9.To treat that the slurry of deironing enters deironing chamber 9 from bottom to top by magnetic Jie net 15 from feeding device 5, then from drawing mechanism 8 out.The irony contained inside slurry is just attracted on magnetic Jie net 15.In said process, the valve of the valve of material returning valve, upper water inlet pipe, residual cake valve, lower water inlet pipe, is all in closed condition.After slurry transferring, the valve closing in pan feeding valve and outlet valve, open the valve of material returning valve, the slurry in deironing chamber 9 flows back to stock tank from feeding back device 14.After feed back, valve open in lower water inlet pipe 4, the rinse water of water tank 2 pumps in deironing chamber 9 by water pump 3, arrival setting-up time, close the valve of lower water inlet pipe 4, open the valve of inlet pipe 7 and the valve port of residual cake valve, water pump 3 continues pump water, and the rinse water of band irony is discharged in slag-draining device 5.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
