Abstract
Description
Technical Field
[0001] The invention relates to the technical field of sand mixing material screening, in particular to a multifunctional sand mixing inspection device. Background Art
[0002] As a key raw material, sand-mixing materials play an important role in many industrial fields such as casting, construction and road construction, especially in the foundry industry, where they are widely used. Sand casting is one of the most commonly used production processes in the foundry industry, accounting for more than 70% of global casting output. In this process, the quality of the sand-mixing materials directly affects the quality of the finished castings, directly affecting their structural strength and dimensional accuracy. The performance stability of the sand-mixing materials is crucial to ensure the quality of castings.
[0003] Sand mixing materials are generally composed of sand, adhesives and other additives. Among them, the particle size distribution and particle morphology of the mixed sand determine the density and permeability of the sand mold, and greatly affect the strength and impact resistance of the performance of the mixed sand. Larger particle size will increase the porosity of the sand mold and enhance the permeability. Although appropriate permeability helps to exhaust, excessive permeability may cause the sand mold surface to be rough or produce sand adhesion defects. At the same time, the gaps between sand particles with larger particle sizes increase, making it difficult to form a tight sand mold structure, resulting in reduced density, loose structure, and reduced strength and impact resistance of the sand mold. In the subsequent pouring process, the sand mold may not be able to withstand the scouring pressure, resulting in damage to the sand mold, which will reduce the yield rate, and may also lead to rework or scrapping, increasing production costs. Summary of the invention
