Abstract

The invention belongs to the field of production of oil sludge and particularly relates to a recycling treatment process of waste oil sludge. The recycling treatment process of waste oil sludge comprises the following steps: stirring waste oil sludge powder, then hot pressing, uniformly spraying tung oil on the hot-pressed oil sludge pieces, rolling the oil sludge pieces sprayed with tung oil to form an oil sludge roll via a rolling machine, uniformly coating the upper layer and the lower layer of the oil sludge roll with the tung oil; continuing to crush the oil sludge roll with the upper layer and the lower layer which are uniformly coated with the tung oil, hot pressing and molding the oil sludge roll into a piece layer, repeating processes of rolling and crushing for 3-4 times to more uniformly stir and mix the tung oil and the waste oil sludge powder. Through a method of crushing the waste oil sludge, adding additives and uniformly mixing tung additives, the oil sludge with high viscosity, fine and smooth in texture, high softness and plasticity, low in extension and retraction along with the temperature and low possibility of deformation can be prepared; the waste oil sludge is recycled; the production cost is reduced; the problem that the conventional direct combustion treatment method of the waste oil sludge causes the waste of the oil sludge resource, generates a large amount of carbon dioxide and easily leads to a greenhouse effect can be solved.

Description

technical field [0001] The invention belongs to the field of oil sludge production, and in particular relates to a process for recycling and regenerating waste oil sludge. Background technique [0002] The clay model is a car body model that is sculpted with clay in traditional body design. It is mainly used to express the actual effect of car styling for the approval of designers and decision makers. Now, computer-aided design has been widely used in the design process, but the clay model is still widely used because of its high efficiency and authenticity of expression. [0003] Since the clay model modeling is actually a sculpture process, it is necessary to use clay that is easy to process and modify by hand. In the production and development of clay models, the sludge used in body modeling is similar to ordinary plasticine, but the requirements are higher. The main components of the sludge are 62% talcum powder, 30% Vaseline, and 8% industrial wax. The stylist spread...
