Embodiment Construction

[0006] A new process for all the waste shells of paraffin wax precision casting to be recycled. First, the waste shells are collected, and then the shells are rolled and thrown by a polygonal roller to make the broken solids of the shell fall onto the conveyor belt through the notches on the cylinder surface, and the debris is removed from the mouth. , The iron block is removed by the magnetic roller, and then fed into the grinder through the conveyor belt, and then fed into the layered vibrating screen to obtain different specifications of sand, and finally classified, weighed and packaged. The entire recycling preparation process can save a lot of costs and create greater profit margins for enterprises.

Abstract

The invention discloses a technological process of a Lost-wax casting waste shell total regeneration utilization new process. The new technological process of the invention comprises the following steps: waste shell collection -roll-polishing and impurity removal-de-ironing by magnetic force -refining and crushing-laying screening - measurement and package, the technological process produces regeneration sand particles by adopting a mechanical matching coordinated process. The invention is energy-saving and environment-protective, thereby bringing good overall economic efficiency.

Description

Technical field [0001] The invention relates to a waste utilization and preparation method, and is particularly suitable for a new process for all regeneration and utilization of lost wax precision casting waste shells of casting molding sand and mold shells. Background technique [0002] When the lost wax is used for precision casting of general machinery parts, there are about 350 kilograms of discarded shells per ton of steel castings. These shells are made of quartz powder, quartz sand, mullite powder, and mullite as a whole through a binder. After being baked and molded, the products are usually cleaned out of the workshop, hauled and abandoned in the wilderness, and freight is required. The raw materials of this type of shell are made by crushing natural ore, about 500 yuan per ton, and the ore reserves are getting less and less, resulting in higher cast steel costs. Summary of the invention [0003] The purpose of the present invention is to provide a new process for all r...
