Description

Technical Field

[0001] The utility model relates to the technical field of smelting equipment, in particular to a filtering device for treating water-quenched tailings. Background Art

[0002] Water-quenched slag is the abbreviation of water-quenched basic iron furnace slag. It is a granular slag with a rough and porous surface, light and brittle texture, and easy to break. At present, water-quenched slag is produced by various methods, including water-quenched slag produced by bottom filtration method. The bottom filtration method water-quenched slag (OCP) is to quench the slag at the slag flushing point at the end of the blast furnace slag ditch by impacting the slag with water with a certain pressure and flow. The slag after water quenching enters the filter tank with the water flow through the slag flushing ditch. The water-quenched slag after precipitation and filtration is taken out from the filter tank by an electric grab and transported as finished water slag.

[0003] The existing filter tank is generally flat-bottomed. When the water-quenched slag is grabbed by a grabber, a large amount of residue will remain, resulting in the filter residue being not cleaned up properly, which is not convenient for cleaning the filter tank. Long-term accumulation can easily lead to clogging and damage of the filter tank. For example, the Chinese patent with the publication number CN210636004U discloses a water-quenched slag filtering agitator, including a driving mechanism and a stirring mechanism. The driving mechanism includes a driving motor, the output shaft of the driving motor is connected to a reducer, and a driving wheel is arranged on the output shaft of the reducer, and the driving wheel rotates in the horizontal direction; the driving mechanism also includes a bearing wheel, the bearing wheel rotates in the vertical direction, and the stirring mechanism is vertically on the bearing wheel and rotates relative to the bearing wheel, and the stirring mechanism includes a circular enclosure, the circular enclosure is in contact with the driving wheel, and the driving wheel drives the stirring mechanism to rotate. The utility model realizes driving by a driving motor, so that the circular enclosure follows the rotation, and the stirring transmission of the agitator is realized during the rotation of the circular enclosure. This agitator structure can adjust and move the water-quenched slag in the filter tank to a concentrated area, which is convenient for thorough treatment of the water-quenched slag and reduces the residue of the water-quenched slag.

[0004] Although the water-quenched slag filtering agitator is convenient for thorough treatment of the water-quenched slag, it is not convenient for cleaning and replacing the filter plate. For this reason, we propose a filtering device for water-quenched tailings treatment to solve the above problem. Utility Model Content
