Description

Technical Field

[0001] The utility model relates to the technical field of fluid meter cleaning in petrochemical industry, in particular to a movable cleaning device for a mass flow meter and a flow meter transmission platform thereof. Background Art

[0002] Mass flow meter is a kind of equipment widely used in industrial fluid measurement and control. Its accuracy and stability are crucial to the continuity and efficiency of industrial production. During the long-term operation of the mass flow meter, due to the influence of wax and colloid components in crude oil and other substances, wax will appear on the inner wall of the measuring tube of the mass flow meter. In addition, impurities and particles in crude oil will also cause blockage and wear during use, affecting the measurement accuracy of the mass flow meter. Therefore, it needs to be cleaned and maintained regularly.

[0003] At present, the cleaning of mass flow meters is mainly done manually, which is inefficient and has great safety risks: on the one hand, manual cleaning requires a lot of manpower and time, and the cleaning effect is often difficult to guarantee;

[0004] On the other hand, since the cleaning process involves some toxic and harmful chemicals, improper operation can easily cause harm to the health of workers; in addition, most existing cleaning equipment is designed with a single function and can only meet some simple cleaning needs. With the continuous development and progress of industrial production, the types and specifications of mass flow meters are increasing, and a single cleaning device can no longer meet the complex and changing cleaning needs. Therefore, the development of a mass flow meter cleaning device that can achieve automated and efficient cleaning has important practical significance and broad application prospects.

[0005] After searching, the following related patent technologies have appeared in the production site: Patent application number: CN201821541113.2 discloses an online cleaning device for a crude oil mass flowmeter, the device includes a measuring part, the measuring part includes a measuring branch pipe, a mass flowmeter is provided in the measuring branch pipe, the cleaning part includes a cleaning liquid pump and a box for containing the cleaning liquid, the cleaning liquid pump is directly connected to the drive motor through a coupling, the cleaning liquid pump provides power for liquid flow, the sewage circuit discharges the dirty oil in the measuring circuit, the cleaning circuit cleans the mass flowmeter, and soaks the measuring branch pipe, and the dirty oil and remaining cleaning liquid are discharged back to the main oil circuit.

[0006] The above device is an online cleaning device for mass flowmeters, which can effectively prevent and eliminate wax deposition, has good cleaning quality, and does not cause residual crude oil discharge pollution. However, the above device is relatively complex as a whole.

[0007] Patent application number: CN201721654810.4 discloses an asphalt mass flowmeter cleaning device, wherein a measuring tube is installed on the flowmeter body. The asphalt mass flowmeter cleaning device has a simple structure, and the rotating box is rotated manually to make the U-shaped elastic rod move in an arc in the measuring tube, and the bristles on the cylindrical box are used to sweep and clean the inner wall of the measuring tube. At the same time, by connecting to an external power supply, the motor drives the second gear to rotate, the second gear meshes with the first gear, and the first gear meshes with the annular rack, so that the cylindrical box finally rotates, and the rotation direction is opposite to that of the second gear, further increasing the cleaning efficiency. Because the cylindrical box rotates in opposite directions to the second gear, the push rod will intermittently push the swing rod, and under the action of the spring, the wiping plate vibrates, so that the scaling part of the inner wall of the measuring tube is easy to be cleaned.

[0008] The above patented technology mainly solves the cleaning problem of asphalt mass flowmeter, mainly by adding a combination structure of wiping plate and bristles to make the rotating box rotate, and use the bristles on the cylindrical box to sweep and clean the inner wall of the measuring tube. However, it is not suitable for crude oil mass flowmeter.

[0009] Patent application number: CN202221387843.8 discloses a flow meter cleaning device, including a cleaning rack, a vertical rod is rotatably penetrated inside the cleaning rack, a turntable is fixedly provided on the top of the vertical rod, a plurality of support plates are fixedly provided at the lower end of the cleaning rack, a water collecting tank is contacted with the top of the support plate, a vertical plate is fixedly provided on the top of the cleaning rack, a water guide pipe is fixedly provided on the upper end of the side wall of the vertical plate, a water inlet pipe is connected between the water guide pipe and the water collecting tank, a pump body is fixedly sleeved on the pipe wall of the water inlet pipe, a nozzle is connected to the end of the water guide pipe, a conduction pipe is connected inside the water guide pipe, a first transmission mechanism is provided inside the conduction pipe, and a second transmission mechanism is provided at the lower end of the vertical rod.

[0010] The above utility model can fully rotate and clean the flow meter, improving the convenience of cleaning the flow meter. However, it is not suitable for quick cleaning of larger flow meters, and the transmission tube needs to go deep into the flow meter, which is not suitable for instruments with precise internal requirements such as mass flow meters.
