Coal sample viscosity judgment method used for coal sample collection and preparation integration

Abstract

The invention discloses a coal sample viscosity judgment method used for coal sample collection and preparation integration. The method comprises the following steps: S1: setting a distinguishing threshold value; putting coal samples with standard viscosity in collection and preparation integrated coal sample detection equipment, and detecting the real-time current value of a driving motor in a rotary wiping device as the distinguishing threshold value when wiping operation is carried out on the coal samples with standard viscosity in a rotary wiping position; S2: monitoring the coal sample viscosity in real time; during normal operation of the collection and preparation integrated coal sample detection equipment, monitoring the current value of the driving motor in the rotary wiping device in the integrated coal sample detection equipment in real time when the coal samples pass through the rotary wiping position; sending the coal samples to drying equipment to be processed when the current value is more than the distinguishing threshold value; sending the coal samples to a next position behind the rotary wiping device in the collection and preparation integrated coal sample detection equipment to be processed when the current value is less than or equal to the distinguishing threshold value. The method has the advantages of simple principle, extreme simplicity and convenience in operation, high precision, and the like.

Description

technical field [0001] The invention mainly relates to the field of coal sample collection and production integration equipment, in particular to a coal sample viscosity judging method suitable for coal sample collection and production integration. Background technique [0002] Due to different coal sources, types, grades, and batches of coal, some coals may have coal sticking, coal blocking, and equipment jamming when they enter the sampling and sample preparation process. For this reason, it is necessary to pass some pre-discrimination to make the process of sampling, sample preparation and sampling and sample preparation go smoothly, and improve the reliability and accuracy of sample collection and preparation under the premise of ensuring the degree of automation. None of the traditional methods are designed based on the automatic operation of procurement and production, so they have the following deficiencies: [0003] In the whole process of sampling and sample prepar...

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.
