Research Of The Automatic Vortex Sand Washer

The molding sand is the molding material by mixing the base sand, sand Blinder and additive materials, according to a certain proportion.Fines content is an important indicator of Foundry sand, and Molding sand Fines content control will directly related to quality of castings. Accurate and rapid measurement of molding sand fines content are important ways to enhance cast quality,reduce the casting defects.so accurate measurement and control of Foundry Sand sediment is very necessary.This paper analyzed the common automatically sand washer on the market,describing the advantages and disadvantages of each. According to GB/T2684-2009 foundry sand and the mixed material test method in the containing mud volume of determination experiment,there are various defects and insufficient from the analysis of the work principle and the work process. Based on the analysis, this paper is committed to research and design new kind of automatically Vortex sand washer in solution above all, achieved this subject of research and design.The research of the automatically sand washer, with the problem of artificial added water and drainage, and artificial timing, which we shall make improved, through on improved siphon drainage device, select of electromagnetic valve, mixing axis, and fixed disc, and motor and wash sand Cup of introduced, described this design of basic design thought, and design principles and specific of design steps, and made it intelligent and automatic though on, the MCU, the TRIAC and the Optocouplers, to finally completed the design and the study of the automatic Vortex sand washer.This paper gives detailed explanation for chip selection,hardware design,PCB layout,software design,and execute testing and analysis for the output of the automatically Vortex sand washer,The result has been illustrated that the automatically Vortex sandwasher can meet the requirements in industrial application.This sand washer is a intelligent and automatic sand washer with high accuracy and stable performance.
