Detailed Description

As shown in fig. 1-2, a steel mill waste filter material treatment and recovery system comprises a crushing device and a filtration and recovery device.

The crushing device comprises a crushing barrel 1, and two supporting legs are symmetrically and fixedly arranged at the bottom of the crushing barrel 1. Two rotatable crushing rollers 2 are symmetrically installed in the middle of the crushing barrel 1, and two first motors 3 used for driving the two crushing rollers 2 to rotate relatively are installed outside the crushing barrel 1. Crushing cylinder 1 is two the top fixed mounting of crushing roller 2 has feeder hopper 4, feeder hopper 4 is located along it the one end slope of 1 inside of crushing cylinder sets up downwards, and feeder hopper 4 is located vibrator 5 is installed to the bottom of 1 outside one end of crushing cylinder. The crushing barrel 1 is provided with a discharge hopper 6 below the two crushing rollers 2, and the discharge hopper 6 is obliquely and downwards arranged along one end of the discharge hopper which is positioned outside the crushing barrel 1.

The filtering and recycling device comprises a mounting rack 7 fixedly arranged on the ground outside the crushing barrel 1, a material transferring and conveying belt 8 is installed on the upper portion of the mounting rack 7, and one end of the material transferring and conveying belt 8 is located below the discharge hopper 6. Mounting bracket 7 is in the fixed mounting who changes the below slope of material conveyer belt 8 has the sieve 9 that shakes, the higher one end of sieve 9 that shakes is located change the below of the other end of material conveyer belt 8, the sieve that shakes is the lower one end of 9 and is open structure and extends to the position that the bottom is close to the inside of crushing barrel 1. The installation 7 is provided with a recovery conveyer belt 18 under the vibrating screen 9.

Be provided with in the crushing barrel 1 and be used for with the waste material that the 9 open ends of sieve that shakes fell is transported to two feed back mechanism on the crushing roller 2, it is specific, feed back mechanism include rotation of bisymmetry install in last sprocket 10 of the inside upper end of crushing barrel 1 and the rotation of two pairs of symmetries install in lower sprocket 11 of the inside lower extreme of crushing barrel 1. And a transmission plate chain 12 matched with the upper chain wheel 10 and the lower chain wheel 11 is wound and arranged between the two pairs of upper chain wheels 10 and the two pairs of lower chain wheels 11, and a plurality of inclined material transferring plates 13 are fixedly arranged on the inner side of the transmission plate chain 12 at uniform intervals. A second motor 14 for driving one of the upper chain wheels 10 to rotate is installed at one end of the upper part of the crushing cylinder 1.
