Description

Technical Field

[0001] The utility model relates to the field of liquid level gauges, in particular to a magnetic panel indicator and a magnetic flap liquid level gauge. Background Art

[0002] The raw water used in power plant boilers is typically river water. The feed water treatment system for power plant boilers follows the following process: raw water → mechanical accelerated clarifier (with only polyaluminium chloride added) → valveless filter → mechanical filter → activated carbon filter → cationic bed → carbon dioxide remover → anionic bed → mixed bed → desalted water tank. The desalted water tank is used to store desalted water that meets power plant requirements. Its primary function is to ensure the water quality and prevent contamination. The design and material selection of the desalted water tank are crucial, as boiling water containing impurities can cause scale, which can corrode the boiler and affect power generation efficiency.

[0003] Desalted water tanks are very large, so they all require magnetic level gauges to monitor the liquid level. Magnetic level gauges are designed based on the principles of buoyancy and magnetic coupling. They are popular among users for their simple structure, intuitive display, and easy installation and maintenance. They are currently one of the most common instruments for level measurement, widely used in the petroleum and chemical industries. As the liquid level in the measured container rises or falls, the magnetic float in the level gauge's main tube also rises and falls. The permanent magnet within the float transmits magnetic force to the magnetic indicator via magnetic coupling, causing the red and white indicator columns to rotate 180°. As the liquid level rises, the indicator column turns from white to red, and from red to white as the liquid level drops. The intersection of the red and white indicators indicates the actual liquid level inside the container, providing a clear indication of the liquid level. Magnetic level gauges can be used to monitor the liquid level of various media in towers, tanks, troughs, spherical vessels, and boilers. Although existing magnetic level gauge technology is highly mature and widely used, it still presents at least the following challenges:

[0004] 1. Magnetic flap level gauges are usually placed in the open air and exposed to the sun and rain for a long time. Over time, the cover made of acrylic sheet on the surface will age and discolor, and the transparency will be greatly reduced, which is not conducive to observation and makes it difficult to see the liquid level. Therefore, the acrylic sheet on the surface must be replaced every once in a while, especially when the height of the magnetic flap of the desalination tank is greater than 8 meters. When replacing the long acrylic sheet, it is necessary to manually climb a ladder to replace it, and high-altitude work is also dangerous.

[0005] 2. In large factories, the number of magnetic flap level gauges used is large, and replacing the cover made of new acrylic sheets every once in a while is also a large cost expense. Utility Model Content

[0006] The purpose of the utility model is to at least solve the problem that high-altitude work is required when replacing the aging acrylic plate on the surface of the existing ultra-high-sized magnetic flap liquid level gauge.

[0007] In order to solve the above technical problems, the utility model provides a magnetic panel indicator, comprising:

[0008] An indicator body, wherein a row of magnetic flip plates are arrayed in the indicator body; the front of the indicator body has an observation window at a parallel angle to the magnetic flip plates; the side of the indicator body has a disassembly slot connected to the observation window;

[0009] There are at least two transparent plates, the at least two transparent plates are in the same straight line and can be detachably mounted on the observation window; the length of the disassembly slot is greater than the length of one transparent plate but less than the length of two transparent plates;

[0010] A ruler is fixedly connected or detachably connected to the surface of the indicator body, and the ruler is at a parallel angle to the observation window.

[0011] As a preferred embodiment of the magnetic panel indicator of the present invention, it comprises a sealing cover, which is detachably mounted on the disassembly slot.

[0012] As a preferred embodiment of the magnetic panel indicator of the present invention, the sealing cover and the indicator body respectively have connecting holes located at the same axis;

[0013] A bolt is included, and the bolt is threadedly connected to the connecting hole of the sealing cover and the indicator body.

[0014] As a preferred embodiment of the magnetic panel indicator of the present invention, the surface of the indicator body has at least one disassembly hole connected to the observation window, and the position of the disassembly hole is not higher than the horizontal height of the disassembly slot.

[0015] As a preferred embodiment of the magnetic panel indicator of the present invention, the surface of each transparent plate has at least one layer of detachably connected transparent film.

[0016] The utility model magnetic flap liquid level gauge comprises any one of the magnetic panel indicators described above,

[0017] The liquid level meter comprises a main body, a magnetic float is provided in the main body of the liquid level meter, a sewage valve is provided below the main body of the liquid level meter, and the main body of the liquid level meter comprises a first connecting pipe and a second connecting pipe;

[0018] The magnetic panel indicator is fixedly mounted on the liquid level meter body.

[0019] As a preferred embodiment of the magnetic flap level gauge of the present invention, the first connecting pipe has a first flange that is fixedly connected; the second connecting pipe has a second flange that is fixedly connected.

[0020] Beneficial effects

[0021] The present invention solves the above existing problems and other existing problems not mentioned above and accordingly brings at least the following innovative advantages:

[0022] The magnetic panel indicator and magnetic flap liquid level gauge of the utility model are provided with a disassembly and assembly slot, so that when a new transparent plate needs to be replaced, the transparent plate at the bottom can be taken out from the disassembly and assembly slot on the side, and the transparent plate at the top will slide downward at this time, so that the next transparent plate can be removed; the utility model realizes the replacement of transparent plates without climbing a ladder, and the replacement process is safer, which solves the current dangerous problem of replacing acrylic plates during high-altitude operations.

[0023] The magnetic panel indicator and magnetic flap liquid level gauge of the utility model can protect the transparent plate by arranging a transparent film on the surface of the transparent plate. When the surface of the transparent plate has multiple layers of transparent films, a layer of the transparent film on the surface can be torn off at regular intervals, thereby keeping the surface of the transparent plate clean without replacing a new transparent plate. At the same time, the frequency of replacing the transparent plate can be reduced, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The utility model magnetic panel indicator, through the disassembly slot 4 is set, see Figure 1 and Figure 2, so that when a new transparent plate 5 needs to be replaced, the bottom transparent plate 5 can be removed from the side disassembly slot 4. At this time, the transparent plate 5 on the top will slide downward, so that the next transparent plate 5 can be removed, until all transparent plates 5 are removed. The utility model realizes the replacement of transparent plates 5 without climbing a ladder, making the replacement process safer and solving the current dangerous problem of replacing acrylic plates at height. When removing the old transparent plate 5 and installing the new transparent plate 5, the new transparent plate 5 is installed into the observation window 3 from the position of the disassembly slot 4, and the transparent plate 5 previously installed in the observation window 3 is pushed upward, and the next transparent plate 5 can be installed.
