A Simple and Practical Water Analyzer

Abstract

The invention relates to a simple and practical continuous hydraulic classification device. A simple and practical elutriator is characterized by comprising a cross-shaped base, a hollow center shaft, upper and lower double-layer disk brackets, an upper conical rolling shaft, a lower conical rolling shaft, a telescopic pull rod, funnel brackets, easy disassembly and cleaning classifiers, a silicone tube, and an organic glass tube; 4-6 easy disassembly and cleaning classifiers are arrayed from small diameter to large diameter; an outlet of a small funnel communicates with an inlet at the lower part of the first easy disassembly and cleaning classifier through a guide pipe, and an inlet and an outlet of each adjacent easy disassembly and cleaning classifiers communicate with each other through a guide pipe. The simple and practical elutriator is capable of dividing a whole-grade material with the screening particle size of -74 [mu]m into relatively narrow particle grades of +74, -74+38,-38+19, -19+10, and -10 [mu]m (or other particle grades), and materials with narrow particle grade and for chemical testing are obtained; a classification conical funnel of the device can be disassembled and cleaned, has the advantages of convenience in material addition and material collection and taking, convenience in operation, safety, reliability, and high classification particle size, and is suitable for fine classification of the -74 [mu]m fine-particle whole-grade material.

Description

technical field [0001] The invention relates to a simple and practical continuous hydraulic grading device. Background technique [0002] In the process of mineral processing and material separation, the particle size and particle size composition of the material have an important impact on its crushing and separation effects. It is often necessary to investigate the particle size and particle size composition of the material and its change characteristics, and to understand the grade of each particle size of the material and its changes. Generally, there are various methods for particle size measurement, such as sieving, elutriation, laser particle size analyzer, microscope observation and particle size statistics, but various methods have their applicability and characteristics of particle size, such as: sieving is only used for millimeters The coarser particles of the grade; the elutriation method is discontinuous, time-consuming, water-consuming, low-precision, and poor...

Problems solved by technology

Generally, there are various methods for particle size measurement, such as sieving, elutriation, laser particle size analyzer, microscope observation and particle size statistics, but various methods have their applicability and characteristics of particle size, such as: sieving is only used for millimeters The coarser particles of the grade; the elutriation method is discontinuous, time-consuming, water-consuming, low-precision, and poor repeatability; the laser particle size analyzer can only obtain the particle size distribution, but cannot obtain samples for analysis and testing, so its quality and efficiency cannot be inspected and comprehensive efficiency; microscope observation statistics are similar to the results of laser particle size analyzers, and are time-consuming and labor-intensive

[0003] At present, there are few experimental devices for hydraulic classification in the laboratory, and the elutriation method is usually discontinuous, time-consuming, water-consuming, low-precision, and poor in repeatability; The water analyzer is either complicated in equipment or complex in operation, and has disadvantages such as unstable control, inconvenient operation, and influence on the observation of grading effects. Therefore, it affects the grading process, and its stability is poor, which seriously affects the inspection and evaluation of grading results.
