Roller treatment process and treatment device suitable for total-amount steel slag treatment

A roller treatment device for total-amount steel slag treatment, comprising a feeding system, a roller unit (5), a particulate slag conveying and storing system (7), a tail gas emitting and purifying system (6), a cooling water circulating system (8), a cold steel cleaning mechanism (10) and an electronic control system (9);

• wherein the feeding system comprises a slag tank tilting mechanism (1), a slag tank (2), and a slag removal machine (4);
• wherein the slag tank tilting mechanism (1) is arranged off-set above a feeding chute (51) in the roller unit (5);
• the slag tank tilting mechanism (1) comprises a hydraulic mechanism and two tank holding arms, wherein the hydraulic mechanism is configured to drive the slag tank tilting mechanism (1) to move forward and backward along a horizontal rail, and the hydraulic mechanism is configured to drive the two tank holding arms to lift the slag tank (2) and control the slag tank (2) to rotate at an angle of 0-180 degrees;
• wherein a steel framework is used for the feeding chute (51), which comprises a chute frame having a top larger than a bottom;
• a chute wall surface directly receiving the molten slag (3) has an angle θ of no less than 35° relative to a horizontal plane;
• a heat resistant lining plate (51-1) is attached to an inner wall at a side receiving the molten slag;
• a reinforcing rib (51-4) and a supporting plate (51-3) are arranged at a side opposite the side receiving the molten slag;
• an end face of the supporting plate (51-3) contacts the chute frame, and another end face thereof contacts a stand positioned on the ground;
• wherein a positioning shaft (51-2) is arranged at a bottom of the chute frame, wherein the positioning shaft (51-2) acts to position the feeding chute (51);
• a pin shaft (51-5) is arranged at a top of the chute frame, wherein the pin shaft (51-5) is used to hoist the feeding chute;
• a steel plate (51-6) having a groove shape is arranged at the top of the chute frame for reinforcing and aid in positioning of the feeding chute;
• and
• wherein the slag removal machine (4) comprises a slag raking head (41), an extendable rod (42), a support (44) and a second hydraulic mechanism (45), wherein the slag raking head (41) is fixed to a frond end of the extendable rod (42);
• the extendable rod (42) is arranged on the support (44), wherein the extendable rod (42) is configured to extend forward and backward, and rotate up and down, left and right under control of the second hydraulic mechanism to rake the slag from the slag tank into the feeding chute (45).
