of sewage, and the scraper 13 and the annular magnetic plate 25 are completely matched in structural size and position in a corresponding mode.

The working principle and the using process of the invention are as follows: when the slag-removing device is used, firstly, waste slag produced by a steel mill is conveyed into the conical storage hopper 17 through the receiving hopper 6, then the motor 22 is started, the motor 22 rotates to drive the axis turntable 24 to rotate at a constant speed, the waste slag stored in the conical storage hopper 17 enters the cavity between the conical storage hopper 17 and the material separating barrel 8 through the discharge opening 18 along the cone arranged at the axis of the conical storage hopper 17 under the double actions of centrifugal force and the self gravity of the waste slag when the conical storage hopper 17 rotates, and enters the first storage area 10 and the second storage area 11 through the lower pressure limiting plate 9 (when the first storage area 10 and the second storage area 11 are filled with the waste slag, the limiting plate 9 is not opened, and simultaneously the waste slag between the conical storage hopper 17 and the material separating barrel 8 continuously moves along with the rotation of the axis turntable 24), meanwhile, the axis turntable 24 rotates and simultaneously waves the rotating roller 20 through the arc folding groove 21, stirs the rotating roller 20 to move towards one side of the second storage area 11, and simultaneously drives the rotating roller 20 to rotate per se, so as to extrude and grind the waste slag in the area of the second storage area 11, when the rotating roller 20 is stired, the waste slag with smaller volume flows out and reaches the surface of the annular magnetic plate 25, the metal is adsorbed by the magnetic action of the annular magnetic plate 25 per se, the metal adsorbed on the surface of the annular magnetic plate 25 is scraped out through the scraper plate 13 during rotation and enters the inside of the storage disc 15 through the guide block 14 for storage, thereby completing the operation of recycling and reusing the metal substances in the waste slag, the waste water generated by steel production can be conveyed to the inside of the treatment device matrix 1 through the water inlet pipe 7 (the waste water can also contain recyclable metal), waste water can be used for lubricating waste residues to a certain extent when the waste residues are crushed or ground, nonmetal impurities in the waste residues can be washed away to be reused, the waste residues and the waste water are combined to be treated by the device, the problem of large volume is solved, meanwhile, compared with a mechanical extrusion crushing mode adopted by the conventional waste residue treatment, the waste residues are crushed more efficiently by steps and layers in a grading mode, the harm caused by dust is greatly reduced by matching with the lubrication of sewage, the sewage generated by treatment is stored in the water storage tank 16 and can be discharged through the sewage discharge interface 23, the waste gas between the treatment device base body 1 and the material receiving funnel 6 can be conveyed to the inside of the ventilation box 4 through the exhaust fan 5 in the whole treatment operation, and the waste gas is filtered by using an activated carbon block filled in the ventilation box 4, thereby reach the processing operation to waste gas, ventilation box 4 sets up between receiving hopper 6 and processing apparatus base member 1 simultaneously, when going into to receiving hopper 6 inside with the waste residue, the same accessible exhaust fan 5 of flying dust of produced is handled, and all consumer all supply power through external power source in this device.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
