[0002] Offshore oil platforms, as integrated processing facilities for oil extraction, often require various chemicals to separate oil and water and treat wastewater during production processes. Therefore, accurate monitoring of chemical levels is crucial to ensuring stable production and efficient operations.
[0003] At present, offshore oil platforms often use magnetic flap level gauges to detect the liquid level information of chemicals used for oil-water separation or sewage treatment in containers. On the one hand, the magnetic flap level gauge will have poor measurement accuracy due to electromagnetic interference from the external environment. On the other hand, after long-term use, the solid impurities or viscous substances contained in the chemicals will adhere to the tube body and float surface of the magnetic flap level gauge, causing the float to get stuck or even directly block the level gauge, making it impossible to measure correctly. Operators cannot make real-time and accurate judgments on the liquid level of the chemical in the container, causing great inconvenience to production operations. Utility Model Content
[0004] In view of this, the utility model aims to propose an anti-interference liquid level display device, which uses the dual display function of a magnetic flap liquid level gauge and a transparent tube to provide real-time and accurate liquid level information of chemical agents in a reaction container to facilitate production operations.

[0007] Furthermore, the first curved pipe is connected to a fixing seat at the flange corresponding to the transparent pipe, and a sealing gasket is provided between the connected flanges; the second curved pipe is provided with a connecting seat at one end corresponding to the transparent pipe;
[0008] The fixing seat and the connecting seat are respectively provided with a socket corresponding to the transparent tube, and both ends of the transparent tube are respectively inserted into the corresponding sockets, and the transparent tube and the hole wall of the corresponding socket are sealed by a sealing ring.

[0010] Furthermore, the inner diameter of the first curved pipe, the inner ring size of the sealing gasket and the inner diameter of the transparent tube are the same, and the lower end of the transparent tube abuts against the sealing gasket.
[0011] Furthermore, the transparent tube is a glass tube.

[0013] Furthermore, the first curved pipe and the second curved pipe are respectively provided with ball valves; and the upper branch pipe of the two branch pipes is provided with a flushing interface.

DETAILED DESCRIPTION
[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0024] like Figure 1 As shown, an anti-interference liquid level display device includes a magnetic flap liquid level gauge body 1 and a transparent tube 8. Openings are respectively provided at the top and bottom ends of the magnetic flap liquid level gauge body 1, and the openings at both ends are respectively provided with connecting flanges, wherein the bottom opening is connected to a drain pipe 2, and a drain valve 4 is provided at the outlet of the drain pipe 2. Two branch pipes 12 are connected to the upper and lower sides of the tube wall of the magnetic flap liquid level gauge body 1 for connecting to a closed container. The magnetic flap liquid level gauge body 1 is a conventional structure and is not described in detail here. The transparent tube 8 can be an acrylic transparent tube, a plastic transparent tube or a glass tube, preferably a glass tube. The transparent tube 8 is arranged side by side on one side of the magnetic flap level gauge body 1. The upper end of the transparent tube 8 is connected to the top opening of the magnetic flap level gauge body 1 through the second bend 10, and the lower end of the transparent tube 8 is connected to the drain pipe 2 through the first bend 5. For example, a three-way joint 3 is arranged in the drain pipe 2, and the first bend 5, the magnetic flap level gauge body 1 and the drain valve 4 are each connected to an interface of the three-way joint 3, and the first bend 5 and the second bend 10 are respectively provided with a ball valve 11.
[0025] In the present invention, the transparent tube 8 is connected to the first bend 5 through the fixing seat 6, and the transparent tube 8 is connected to the second bend 10 through the connecting seat 9. The first bend 5 is an L-shaped bend structure, whose horizontal port is connected to the sewage pipe 2, and its upward port corresponds to and is connected to the transparent tube 8; the second bend 10 is a U-shaped tube structure with a port facing downward, one of which is connected to the top opening flange of the magnetic flap level gauge body 1, and the other port corresponds to and is connected to the transparent tube 8. The connection structure of the transparent tube 8 and the first bend 5 is as shown in FIG. Figure 2 As shown, the connection structure of the transparent tube 8 and the second curved tube 10 is as shown in FIG. Figure 3As shown, the first curved tube 5 is connected to the fixing seat 6 at its upward end flange, and a sealing gasket 15 is disposed between the connected flanges. The inner diameter of the sealing gasket 15 is the same as the inner diameter of the first curved tube 5, the inner diameter of the second curved tube 10, and the inner diameter of the transparent tube 8. The fixing seat 6 and the connecting seat 9 each define a corresponding insertion hole 13 for the transparent tube 8. The lower end of the transparent tube 8 is inserted into the insertion hole 13 of the fixing seat 6, and the bottom end of the transparent tube 8 abuts the sealing gasket 15. The upper end of the transparent tube 8 is inserted into the insertion hole 13 of the connecting seat 9. The upper and lower portions of the transparent tube 8 and the walls of the corresponding insertion holes are sealed by sealing rings 17, respectively, and the transparent tube 8 and the corresponding insertion holes are sealed by the sealing rings 17. The transparent tube 8 and the corresponding insertion holes are sealed by the sealing rings 17. The transparent tube 8 is installed using this structure, which facilitates its installation and disassembly. If the chemical builds up on the wall of the transparent tube 8 and the liquid level is difficult to determine at a glance, the transparent tube 8 can be replaced promptly.
[0026] In order to improve the installation and operation stability of the transparent tube 8, rubber sleeves 18 corresponding to the transparent tube 8 are respectively provided on the upper part of the fixing seat 6 and the lower part of the connecting seat 9. The upper and lower ends of the transparent tube 8 are respectively passed through the corresponding rubber sleeves 18, and the rubber sleeve 18 and the transparent tube 8, the rubber sleeve 18 and the fixing seat 6, and the rubber sleeve 18 and the connecting seat 9 are respectively fixed by clamps 7.
[0027] In the present invention, the liquid level data of the transparent tube 8 can be read by the liquid level scale of the magnetic flap level gauge body 1 at eye level, or a scale value showing the liquid level position can be set on the wall of the transparent tube 8, so that the liquid level data of the transparent tube 8 can be read directly.
[0028] In the present invention, the upper branch of the two branches 12 of the magnetic flap level gauge body 1 is provided with a flushing interface 14 to facilitate flushing of the magnetic flap level gauge body 1. The flushing interface 14 is a threaded structure and is normally sealed. During flushing, the communication channel between the sealed container and the two branches 12 is closed. The flushing interface 14 is opened and connected to the corresponding flushing equipment, the ball valves of the first elbow 5 and the second elbow 10 are closed, and the drain valve 4 is opened. The flushing liquid enters the tube body of the magnetic flap level gauge body 1 through the flushing interface 14, flushing it. After flushing, the liquid is discharged from the drain pipe 2.
[0029] Based on the principle of communicating vessels, the present invention displays the liquid level within a sealed container via a magnetic flap level gauge and a transparent tube 8, achieving dual liquid level measurement and reducing the impact of external electromagnetic interference on liquid level measurement. If the float of the magnetic flap level gauge becomes stuck, affecting the accuracy of the liquid level display, the liquid level data can be obtained through the transparent tube 8. This device can accurately and in real time measure the liquid level of the chemical within the reaction vessel, improving the accuracy and stability of the liquid level display and facilitating production operations. Furthermore, the present device can determine whether the float of the magnetic flap level gauge is stuck or clogged based on the position of the liquid within the transparent tube 8. Specifically, when the liquid level within the transparent tube 8 exceeds the height of the float within the magnetic flap level gauge, it can be determined that the float of the magnetic flap level gauge is stuck or clogged, allowing for subsequent processing.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
