Description

Technical Field

[0001] This invention relates to the field of Coriolis flow meter technology, specifically to a Coriolis flow meter cleaning device. Background Technology

[0002] A Coriolis mass flow meter is a device that directly measures mass flow rate by utilizing the Coriolis force generated when fluid flows in a vibrating pipe, which is proportional to the mass flow rate. It consists of a flow sensing element and a converter. Coriolis mass flow meters achieve direct measurement of mass flow rate, featuring high accuracy and the ability to measure multiple media and process parameters. They are widely used in industries such as petrochemicals, pharmaceuticals, and food processing.

Furthermore, the unique structure of the bent-tube flow meter makes cleaning difficult. Prolonged corrosion from oil and other contaminants can lead to a decrease in the flow meter's accuracy, thus affecting its subsequent use. Summary of the Invention

[0029] In this invention, the box body 1 and the box cover 2 are movably connected on one side via a rotating shaft 5, and the box body 1 and the box cover 2 are fastened together on the other side via a locking mechanism 4. The locking mechanism 4 is composed of one or more of the following methods: snap-fit, magnetic attraction, rotary locking, and slider locking.

[0033] In this invention, a handle 3 is also provided at the center of the top of the box cover 2.

[0034] Example

[0035] In use, first open the locking mechanism 4 at the connection between the cover 2 and the body 1. The locking mechanism 4 can be one or more of the following: snap, magnetic, rotary locking, and slider locking. Then, under the action of the rotating shaft 5, open the cover 2. Next, move the body 1 below the Coriolis flow meter, and then close the cover 2. Connect the cover 2 to the outside of the pipes at both ends of the bent Coriolis flow meter through the pipe joint 6 on the side of the body 1. Lock the cover 2 and the body 1 with the locking mechanism 4. Next, connect the inlet 18 to an external water source, which can be a faucet, water pipe, or other water source. Add water to the water tank 17. Then turn on the water pump 16 and supply water to the cleaning mechanism 7 through the connecting water pipe 15. The cleaning mechanism 7 includes a connector 23 at the end of the connecting rod 22. Multiple high-pressure nozzles 24 are evenly arranged inside the connector 23, and the connector 23 has an overall U-shaped structure. Both the connecting rod 22 and the connecting piece 23 have hollow interiors. The connecting rod 22 is connected to the outlet end of the connecting water pipe 15. The high-pressure nozzle 24 inside the connecting piece 23 of the cleaning mechanism 7 cleans the surface of the Coriolis flowmeter. Simultaneously, the drive device 9 of the drive mechanism drives the transmission gear 21, which in turn moves downwards along the inside of the slide groove 10 under the action of meshing with the transmission belt 11. When the drive device 9 rotates in the reverse direction, the cleaning mechanism 7 moves in the opposite direction. The slide groove 10 has an arc-shaped structure, and the slide grooves 10 on both sides combine to form a U-shaped structure, which can completely cover the surface of the bent-tube Coriolis flowmeter. This ensures that the high-pressure nozzle 24 can completely clean the surface of the Coriolis flowmeter. A water collection tank 14 is provided between the drive mechanism and the water tank 17 inside the housing 1. A filter plate 13 is installed on the top of the water collection tank 14, and the water collection tank 14 is generally conical. The filter plate 13 is connected to the guide rails on both sides of the box 1 by sliders on both sides. A handle 25 is also provided on the outside of the filter plate 13. During the cleaning process, the sewage is filtered by the filter plate 13, leaving the impurities on the surface of the filter plate 13. The sewage flows into the water tank 17. After cleaning, the valve 20 on the outside of the outlet 19 is opened to discharge the sewage.
