Abstract
The invention discloses a recycling low-carbon treatment process for waste steel slag containing grinding fluid, and belongs to the technical field of waste steel slag recovery. The invention is used for solving the technical problems that the difficulty in cleaning the greasy dirt on the surface of the waste steel slag is high, the removal effect and the removal rate of the greasy dirt are required to be further improved, and the recycling low-carbon treatment process of the waste steel slag containing grinding fluid comprises the following steps: adding clean water into one liquid storage tank, which is close to the material tank, on the cleaning device; and adding the scrap steel slag into a storage cavity on a storage ring of the cleaning device, contracting an electric telescopic rod, wherein one cleaning barrel descends into a material box, and driving the storage ring to ascend through a lifting ring and a connecting rope. The invention not only effectively improves the cleaning effect of the waste steel slag, but also can automatically feed the waste steel slag. And the blanking is carried out, so that the cleaning rate of the steel scraps is effectively improved, waste gas is not generated in the cleaning process, and the method is more environment-friendly.
Description
Technical Field
The invention relates to the technical field of waste steel slag recovery, in particular to a recycling low-carbon treatment process for waste steel slag containing grinding fluid.
Background
In the machining process of the cutter, lubricating oil and grinding fluid are generally used as auxiliary raw materials in machining processes (blanking, turning, tapping, honing and the like), a certain amount of grinding fluid or lubricating oil is adhered to metal scraps and slag generated in the machining process, oil stains are formed outside the waste steel slag, the main components of the waste steel slag are tungsten carbide and cobalt-containing tungsten carbide, and the waste steel slag has great recovery value, but the waste steel slag can be utilized after the oil stains formed by the waste grinding fluid and the lubricating oil on the surface of the waste steel slag are removed in the recovery process, so that the waste steel slag is difficult to directly recycle.
