Sand mixer with enhanced preliminary mixing function

Abstract

The invention relates to a sand mixer with an enhanced preliminary mixing function. The sand mixer is provided with an intelligent composite material inlet, wherein a multi-stage preliminary mixing disk for preliminarily mixing supplied materials is mounted on a main mixing bin; by the adoption of an optimized curved surface material throwing structure with a rotating speed and a rotating direction which are different from the rotating speed and the rotating direction of a main mixing mechanism, a load can be scientifically distributed according to an actual requirement; by the independent design of the mechanical loads and power of a preliminary mixing mechanism and the main mixing mechanism, the mechanical effect is effectively enhanced; a special material conveying opening for supplying an adhesive and / or a curing agent is formed in the middle part or the lower part of the main mixing bin of the sand mixer, so that the workload and the working time of the main mixing mechanism can be reduced to an extremely large extent, and the workload of the preliminary mixing mechanism is also reduced; furthermore, the sand mixer realizes controllability of production from quantitative material feeding and precise temperature control, and equipment works safely and reliably.

Description

technical field

[0001] The invention relates to a casting machine, in particular to a sand mixer with the function of enhancing primary mixing. Background technique

[0002] The material used for molding in casting is molding sand, which is generally made of molding materials such as raw sand, binders and auxiliary materials mixed in a certain proportion. Sand mixers are sand processing equipment used to realize the mixing of the above-mentioned molding sand materials. Sand mixers are often divided into several categories according to the sand mixing process: roller sand mixers mainly for rolling and rubbing; The main vane type sand mixer; the countercurrent or rotor type sand mixer with rubbing and mixing functions and the balance wheel type sand mixer with rolling and mixing functions. In practical applications, due to the different use occasions and mixing purposes, more extensive and flexible means such as stirring, rolling, shaking, turning or a combination thereof are...
