Description

Technical Field

[0001] This utility model relates to the field of magnetic float level gauge technology, specifically a visual magnetic float level gauge display device. Background Technology

[0002] A magnetic float level gauge is a widely used device for measuring liquid level in industrial production. It operates based on the buoyancy characteristics of a magnetic float and the principle of magnetic coupling. The float contains an embedded magnet that moves up and down over the liquid surface. An external series of magnetic sensing elements are installed on the level gauge. These elements detect changes in the float's magnetic field to accurately measure the liquid level and convert this information into a reading for display. This measurement method does not require direct contact with the liquid, making it suitable for various liquid media, especially corrosive liquids or hazardous environments.

[0003] To facilitate intuitive reading of liquid levels, magnetic float level gauges are typically designed with one or more transparent windows on the outside. These transparent sections may be made of high-strength glass or transparent plastic to allow observation of the float's movement or reading of the scale on the external indicator. However, with prolonged use in industrial settings, these transparent surfaces may be accidentally scratched by external particles, chemical corrosion, or strong friction. Furthermore, the accumulation of liquid vapor or dust during operation can lead to the formation of stubborn dirt on the surface, severely affecting the clarity and accuracy of the liquid level readings.

[0004] These transparent structures are key components of level gauges. They are typically fixedly installed and integrated into the overall equipment design. While this design is simple, it presents inconveniences during maintenance. When the transparent window is damaged or becomes dirty, it is often difficult to replace or clean it individually. Users need to perform comprehensive maintenance or replacement of the equipment during production interruptions, increasing operational and economic costs. Therefore, improving the maintainability and replaceability of the transparent window has become an important direction for enhancing the practicality of magnetic float level gauges. In light of this, we propose a visual magnetic float level gauge display device. Utility Model Content

[0005] The purpose of this invention is to provide a visual magnetic float level gauge display device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A visual magnetic float level gauge display device includes a main tube containing a magnetic float. Two symmetrically arranged bypass liquid guide pipes are located on the rear side of the outer wall of the main tube. A bypass pipe connecting flange is located at the rear end of the outer wall of each bypass liquid guide pipe for connecting to a container whose liquid level is to be measured. Liquid from the container enters the main tube through the bypass liquid guide pipes, causing the magnetic float inside the main tube to move up and down with the liquid level. An upper cap is located at the top of the main tube to seal the top and prevent liquid leakage. A lower flange cap is located at the bottom of the outer wall of the main tube for connecting other pipe fittings, such as a drain pipe.

[0008] A flip-plate box is located on the front side of the main tube. The flip-plate box is connected to the main tube by two connecting clamps. A magnetic flip-plate indicator and a scale are located on the front side of the flip-plate box. The liquid level is visualized through mechanical and magnetic principles. The magnetic float inside the main tube contains a magnet. When the liquid level changes, it rises and falls with the liquid surface. The flip-plate box is installed close to the main tube, so that the movement of the magnetic float can directly affect the external magnetic flip-plate indicator. The indicator consists of a row of flippable small indicator pieces, each with a small magnet inside. It interacts with the magnetic field of the magnetic float inside the main tube. When the magnetic float moves to a certain height, the corresponding magnetic flip plate is attracted or pushed, causing the indicator piece to flip, usually changing from white to red or other contrasting colors, thus intuitively displaying the liquid level. The scale parallel to the magnetic flip-plate indicator provides precise height markings so that users can obtain specific liquid level values. Through this magnetic coupling and mechanical flipping process, the flip-plate box allows the operator to easily observe changes in liquid level, ensuring the intuitiveness and accuracy of monitoring. This is existing technology and will not be elaborated further here.

[0009] The front side of the outer wall of the flip box is provided with a frame-shaped docking groove. A protective cover is fitted over the frame-shaped docking groove to protect the magnetic flip indicator and scale from damage and dirt. A transparent acrylic plate runs through the front side of the protective cover to provide good visibility so that users can easily see the liquid level indicator. If the transparent acrylic plate is accidentally damaged, the protective cover can be replaced to ensure the long-term use of the flip box and improve its service life.

[0010] Preferably, the bottom of the main body pipe is provided with a drain pipe, the top of the outer wall of the drain pipe is provided with a connecting flange, the connecting flange is connected to the flange cover flange, and the outer wall of the drain pipe is provided with a control valve. The drain pipe is used to discharge the liquid in the main body pipe, which facilitates maintenance and prevents the accumulation of liquid contamination.

[0011] Preferably, the flip box has U-shaped mounting grooves on both the left and right sides and near the top and bottom ends, and the inner wall of the U-shaped mounting groove has a first threaded groove.

[0012] Preferably, the two ends of the connecting clamp bypass the main body tube and are respectively located in two U-shaped mounting grooves arranged opposite each other on the left and right. The outer wall of the connecting clamp is provided with mounting holes b near both ends. Locking bolts are connected in the mounting holes b. The threaded end of the locking bolt is threaded into the first thread groove, which facilitates the assembly and disassembly of the connecting clamp.

[0013] Preferably, a frame-shaped groove is provided on the rear side of the inner wall of the protective cover, and a frame-shaped sealing rubber is bonded in the frame-shaped groove. The inner wall of the frame-shaped sealing rubber is tightly fitted with the inner side of the frame-shaped mating groove to ensure the sealing of the connection between the protective cover and the flip box, and to prevent dirt or moisture from entering and affecting the magnetic flip indicator and scale.

[0014] Preferably, the front side of the outer wall of the main body tube is provided with two fixing seats arranged symmetrically in the upper and lower positions as the base for fixing the protective cover. The middle of the front side of the fixing seat is provided with a second threaded groove. The upper and lower sides of the protective cover are provided with mounting wing plates. The front side of the mounting wing plate is provided with a mounting hole a. A fastening bolt is connected in the mounting hole a. The threaded end of the fastening bolt is threaded into the second threaded groove, which facilitates the disassembly and assembly of the protective cover.

[0015] Preferably, the front side of the fixing base has two positioning slots arranged symmetrically from left to right, and the rear side of the mounting wing plate has two positioning blocks arranged symmetrically from left to right. The positioning blocks are inserted into the positioning slots to assist in the accurate installation and stable positioning of the protective cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This visual magnetic float level gauge display device is designed with a replaceable protective cover. When the transparent acrylic plate is damaged or affected by dirt, the user does not need to replace the entire device or perform complicated cleaning. Only the protective cover needs to be replaced, which greatly reduces the complexity and time cost of maintenance and improves the maintainability and service life of the equipment.

[0018] 2. This visual magnetic float level gauge display device ensures the sealing of the connection between the protective cover and the flip box by setting a frame-shaped groove on the rear side of the inner wall of the protective cover and bonding a frame-shaped sealing rubber. This effectively prevents dirt or water vapor from entering and causing the magnetic flip indicator and scale to degrade in performance and become unclear, thus ensuring the accuracy and stability of the level indication.

At this time, the positioning block 621 is inserted into the positioning slot 71, and the frame-shaped sealing rubber 8 seals the connection between the protective cover 6 and the flip-plate box 5. Finally, the two fastening bolts 63 are tightened to fix the protective cover 6 in place. Through these steps, the user can effectively and safely use the visual magnetic float level gauge display device to continuously monitor the liquid level changes in the container and perform equipment maintenance and adjustment as needed.
