Abstract

The invention discloses a two-stage vertical type sand washer. The two-stage vertical type sand washer comprises a barrel body, sand washing systems and driving systems, the barrel body adopts a vertical barrel type structure and comprises a primary stirring barrel and a secondary stirring barrel, an opening is arranged between the primary stirring barrel and the secondary stirring barrel, the primary stirring barrel is provided with a material inlet, the secondary stirring barrel is provided with a material outlet, the primary stirring barrel and the secondary stirring barrel are both internally provided with one sand washing system, the sand washing systems adopt blade type sand washing mechanisms, each sand washing system comprises a main shaft, vertical sand washing blades and inclinedsand washing blades, and the main shafts are rotatably connected with the corresponding primary stirring barrel and secondary stirring barrel. According to the two-stage vertical type sand washer, the blade type sand washing mechanisms of the vertical sand washing blades and the inclined sand washing blades are adopted, no damage is caused to sand, the barrel body adopts the vertical barrel typestructure, the two-stage vertical type sand washer is compact in structure, the installation space is saved, with the help of the flow characteristic of flow liquid, water can drive the sand to flow together under the action of the inclined sand washing blades, and energy sources are saved.

Description

technical field [0001] The invention relates to the technical field of sand washing equipment, in particular to a double-stage vertical sand washing machine. Background technique [0002] The water glass process is a commonly used molding process in the production of steel castings, and it is divided into CO2 hardened water glass process and ester hardened water glass process. 1. CO2 hardened water glass process, the residual strength of the sand mold is relatively high when unpacking, only about 20% of the loose sand can be recycled, and the remaining 80% are discarded, which is a serious waste of resources and pollutes the environment, and is increasingly favored by the environmental protection department. Concern; 2. The ester hardened water glass process has been greatly improved compared with the CO2 hardened water glass process. The old sand can be recycled by 75%, but its regeneration system needs roasting and cooling equipment, which consumes a lot of energy and the ...
