Pendulum Viscosity Detection Device Used in Integrated Coal Sample Collection System

Abstract

The invention discloses an oscillating bar type viscosity detection device for an integrated coal sampling system. The oscillating bar type viscosity detection device comprises an oscillating bar assembly located above a coal sample conveying mechanism, a lifting driving assembly and a viscosity judgment sensor, wherein the oscillating bar assembly is installed on the lifting driving assembly and is driven by the lifting driving assembly to do lifting movement to be touched with or departed from a coal sample on the coal sample conveying mechanism; the oscillating bar assembly comprises an upper oscillating bar and a lower oscillating bar, wherein the upper part of the lower oscillating bar is hinged below the upper oscillating bar, the bottom of the lower oscillating bar touches the coal sample, and an a certain angle is formed between the upper oscillating bar and the lower oscillating bar; the viscosity judgment sensor is used for monitoring the position of the upper oscillating bar in real time. The oscillating bar type viscosity detection device disclosed by the invention is simple in principle, simple and convenient to operate and capable of greatly improving automatic working reliability and line production smoothness.

Description

technical field [0001] The invention mainly relates to the technical field of coal quality analysis, in particular to a pendulum-type viscosity detection device suitable for an integrated collection and production system of coal samples. Background technique [0002] The analysis of coal quality is actually a process of sampling analysis. Coal is an inhomogeneous substance (particle size, distribution of quality characteristics, etc.), and the sampled parent stock is generally relatively large (ranging from tens of tons to tens of thousands of tons), and the samples that can represent the quality and characteristics of the entire stock sample are drawn to the maximum extent. The process of a representative sample is called "sampling". At present, there are various methods such as mechanical sampling, manual sampling, and semi-mechanical sampling. Each country has mandatory standards, and sampling work must be carried out in accordance with the standards. After the sample ...

Problems solved by technology

However, due to the strong subjectivity of artificial recognition, there are often phenomena such as missed judgments and misjudgments.

Therefore, before the coal enters the sampling system, a special person is required to be on duty and make judgments. The coal that cannot be processed by the automatic sampling equipment must be manually separated by workers, which results in its high labor intensity, long cycle time, and poor accuracy.
