Description

Technical Field

[0001] The utility model relates to the technical field of coal powder flow measurement, in particular to a coal powder flow measurement device. Background Art

[0002] Coal powder refers to coal particles that have been crushed and are usually used in combustion, power generation, heating and other fields. When the flow of coal powder is detected during transportation, a magnetoelectric coal powder flowmeter is generally used to measure the flow. A magnetoelectric coal powder flowmeter is an instrument for measuring the flow of coal powder. It calculates the flow by measuring the change in magnetic flux when the coal powder flows through a magnetoelectric sensor.

[0003] When coal powder passes through the magnetoelectric sensor, the magnetic flux of the magnetoelectric sensor will change, and the flow rate will be detected according to the change of magnetic flux. However, due to the poor fluidity of coal powder, a part of coal powder will adhere to the inner wall of the magnetoelectric coal powder flowmeter when the coal powder is transported. This part of coal powder will change the magnetic flux of the internal magnetoelectric sensor, resulting in the actual measured flow rate not matching the actual flow rate. Therefore, it is necessary to clean the inside of the magnetoelectric coal powder flowmeter in time after each use. However, since the magnetoelectric coal powder flowmeter is generally installed between the conveying pipes, it is not convenient to clean it.

[0004] Therefore, the utility model provides a pulverized coal flow measurement device to solve the above problems. Utility Model Content
