Program-controlled pipeline pulp sampling apparatus and sampling method thereof

Abstract

The invention discloses a program-controlled pipeline pulp sampling apparatus and a sampling method thereof. The program-controlled pipeline pulp sampling apparatus comprises a maintenance valve, a pipeline washing valve, a backwash valve, a pinch valve and a PLC, the maintenance valve is communicated with a pulp pipeline, and the maintenance valve, the pipeline washing valve, the backwash valve and the pinch valve are connected through a cross joint, one end of the pinch valve is connected with the cross joint, the other end of the pinch valve is connected with a sample pipe, one end of the pipeline washing valve is connected with the cross joint, the other end of the pipeline washing valve is connected with a first pipeline, one end of the backwash valve is connected with the cross joint, the other end of the backwash valve is connected with a second pipeline, one end of the first pipeline far from the pipeline washing valve and one end of the second pipeline far from the backwash valve are respectively connected to two interfaces of a tee joint, the remaining interface of the tee joint is connected with a water source, and the output end of the PLC is electrically connected with the pipeline washing valve, the backwash valve and the pinch valve respectively. The apparatus has the advantages of low cost, simple structure and accurate and reliable sampling.

Description

technical field [0001] The invention relates to the field of sampling devices, in particular to a program-controlled pipeline slurry sampling device and a sampling method. Background technique [0002] At present, metal balance is the soul of beneficiation production technology management, and sampling analysis data is the core data for metal balance calculation. Only through sampling and analysis during the beneficiation process can the process status be reflected and abnormalities discovered in time. Only through sampling and analysis can the operator's operating results be reflected. However, the manual sampling currently used has the following problems. The raw ore fluctuates greatly. The manual sampling every 30 minutes cannot meet the needs and cannot guarantee on-time sampling. The situation of "surprise sampling" occurs from time to time. Frequent replacement of sampling workers, sense of responsibility, and differences in sampling methods will lead to discrepancie...

AI Technical Summary

Problems solved by technology

However, the current manual sampling has the following problems. The raw ore fluctuates greatly. The manual sampling once every 30 minutes cannot meet the needs and cannot guarantee on-time sampling. "Surprise sampling" happens from time to time.

Frequent replacement of sampling workers, sense of responsibility, and differences in sampling methods will lead to discrepancies with the actual situation

The workshop assessment is strict, and manual work will lead to "human feelings"

The quality of manual sampling is uncontrollable and cannot be quantitatively evaluated

Unable to objectively evaluate mineral processing production technology management

However, the existing sampling devices have the problems of high price, complicated structure, complicated installation and long maintenance period.
