Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a disassembly-free cleaning device for a rotor flowmeter. Background Art

[0002] The rotor flowmeter is a flow meter based on a rotating mechanism, commonly used in industrial flow metering equipment. It determines the flow rate of the medium by measuring the rotor rotation speed of the liquid or gas in the pipeline. The rotor flowmeter consists of a flow sensor and a rotor. The rotor is laid on the central axis of the pipeline. The flow sensor detects the frequency of the high-speed rotation of the rotor and converts it into fluid flow data for recording. This device has a simple structure, is easy to install and maintain, and has high accuracy and stability. Therefore, it is widely used in petrochemical, natural gas, hydropower stations, biopharmaceuticals and other fields.

[0003] Since the medium in the chemical plant may contain a large amount of impurities and special materials, the rotor flowmeter may be contaminated by these substances after a period of use, affecting its measurement accuracy and service life. Therefore, the rotor flowmeter needs to be disassembled and cleaned regularly to remove the accumulated impurities and dirt to ensure its normal operation and accurate measurement, and also to avoid the occurrence of inhalation of personnel affecting their health or even poisoning accidents.

[0004] At present, during the cleaning process, it is necessary to close the valve on the pipeline, remove the flowmeter from the pipeline, and use appropriate cleaning agents or solutions to soak the flowmeter components and the sensor surface to effectively dissolve the precipitated dirt and organic impurities. When cleaning, avoid using hard objects such as brushes to scrape the inside of the flowmeter to avoid scratching the components. At the same time, after cleaning, the flowmeter components should be carefully checked to see if they are intact to ensure that they can work normally after reinstallation. The traditional cleaning process is complicated, time-consuming and labor-intensive. Utility Model Content
