Description

Method for selecting molding sand from waste mixed soil for casting molding
Technical Field
The invention relates to the technical field of molding sand selection, in particular to a method for selecting molding sand from waste mixed soil for casting and molding.
Background
In the clay sand foundry process, about 1 ton of waste sand is generated per 1 ton of cast product, and a large amount of clay waste sand is generated each year. The discharge of waste clay sand not only causes pollution to the natural environment, but also is a huge waste to natural resources. In order to reduce the discharge problem of waste clay sand, the complete regeneration technology of old clay sand is widely concerned by casting production enterprises adopting the clay sand process. The complete regeneration of the used clay sand is a regeneration method which removes a binder film on the surface of sand grains through regeneration and simultaneously eliminates the adverse effect caused by the mixing of core sand, so that the performance of the sand is restored to the level of the sand which can be used for a chemical binder. The existing mature clay used sand complete regeneration method comprises a dry method and a wet method. The dry method clay used sand is completely regenerated, and the regenerated sand with the sand performance recovered to the level of the sand used for the chemical binder is obtained through the technical processes of roasting, mechanical or airflow regeneration and micro powder separation. Wet full reclamation reclaimed sand is obtained by scrubbing and roasting that has sand properties restored to levels that can be used as sand for chemical binders. In the process of completely regenerating the used clay sand by the wet method, the effective bentonite, the effective coal powder, the dead clay, the sand scraps, the organic binder film scraps and the like in the used clay sand are all taken away by water in the process of scrubbing the used clay sand, so that the sludge regenerated by the wet method of the used clay sand is formed.
