Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, specifically a highly stable magnetic float liquid level gauge. Background Technology

[0002] Magnetic level gauges are widely used liquid level measurement instruments in industrial fields. They are mainly used to measure and display the liquid level in containers such as tanks, troughs, and boxes. This instrument determines the change in liquid level within the container by measuring the liquid height, thereby achieving liquid level monitoring and control. The working principle of magnetic level gauges is based on the float principle, the communicating vessel principle, and the magnetic coupling principle, and it has advantages such as high accuracy, good stability, and safety and reliability.

[0003] The reference patent is titled "Magnetic Float Level Gauge" (publication number CN220120210U, application date 2023-06-27). The magnetic float level gauge includes a main body, connecting branch pipes, and vibration damping components. The main body includes a measuring main pipe and a scale. A magnetic float movable in a first direction is provided inside the measuring main pipe. The scale is installed on the outer surface of the measuring main pipe, and the side of the scale away from the measuring main pipe has a mounting groove. Multiple magnetic floats are rotatably arranged in the mounting groove. The groove edge is provided with scale lines. The movement of the magnetic float can drive the magnetic floats to rotate. There are two connecting branch pipes, which are located at both ends of the measuring main pipe. The vibration damping components include a damping plate and a spring. The damping plate is connected to the connecting branch pipe by the spring, and the outer periphery of the damping plate is spaced apart from the inner wall of the connecting branch pipe. The spring is extendable in a second direction.

[0004] Based on the aforementioned patent, in the prior art, for measuring corrosive liquids, traditional magnetic float level gauges typically employ an inner lining design to prevent the measured liquid from corroding the float and connecting tube. However, existing lining processes often cause radial deformation of the inner lining of the connecting tube, reducing the size of the through-hole in the middle of the lining and leading to blockage by impurities in the liquid. This not only affects the measurement accuracy of the level gauge but may also pose safety hazards to production. Therefore, this utility model provides a highly stable magnetic float level gauge. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a highly stable magnetic float level gauge, which solves the problem that the lining process of existing magnetic float level gauges often leads to radial deformation of the lining of the connecting tube, causing the through hole in the middle of the lining to become smaller, thus causing impurities in the liquid to clog the lining. This not only affects the measurement accuracy of the level gauge, but may also pose safety hazards to production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable magnetic float level gauge, comprising a level gauge, wherein an upper connecting pipe and a lower connecting pipe are interconnected at the rear of the level gauge, and a baffle plate is fixedly installed on the inner wall of the upper connecting pipe; a filtration mechanism is fixed at the upper end of the upper connecting pipe, the filtration mechanism comprising:

[0007] The filtration assembly is located on the upper part of the upper pipe and includes a filtration box fixed on the upper part of the upper pipe. The filtration box and the upper pipe are interconnected by a first liquid guide pipe and a second liquid guide pipe. A filtration screen plate is inserted into the filtration box, and a handle is fixed on the top of the filtration screen plate.

[0008] The snap-fit ​​assembly is located on both sides of the filter box and the filter screen plate, and is used to snap-fit ​​and fix the filter box and the filter screen plate.

[0009] The cleaning component is installed on the filter box and is used to scrape and clean the filter holes of the filter screen.

[0010] Preferably, the snap-fit ​​assembly includes L-shaped connecting rods fixed to both sides of the top of the filter screen plate, and an elastic telescopic rod is fixed to the lower end of the L-shaped connecting rods.

[0011] Preferably, the elastic telescopic rod has a first trapezoidal block fixed at one end near the filter box, and a second trapezoidal block is fixed on both outer walls of the filter box.

[0012] Preferably, the cleaning assembly includes a mounting rod fixedly installed on the top of the filter box, and a rocker arm is rotatably mounted on the mounting rod.

[0013] Preferably, one end of the rocker arm is fixed with a movable section rod, and the lower end of the movable section rod is rotatably connected to a vertical rod that penetrates the upper wall of the filter box. A brush plate is fixedly installed at the lower end of the vertical rod, and the brush surface on the brush plate is in contact with the filter hole surface of the filter screen plate.

[0014] Preferably, both the upper and lower connecting pipes have anti-corrosion liners fixed to their inner walls, and both the upper and lower connecting pipes have flanges integrally formed on one side.

[0015] Beneficial effects

[0016] This invention provides a highly stable magnetic level gauge. Compared with the prior art, it has the following advantages:

[0017] 1. This highly stable magnetic level gauge features a filtration mechanism. Liquid first enters the filtration box through the first guide pipe. Inside the filtration box, the liquid is filtered by the filtration screen to remove impurities. The filtration screen is securely installed inside the filtration box via a snap-fit ​​assembly. Specifically, the elastic telescopic rod at the lower end of the L-shaped connecting rod pushes the first trapezoidal block to engage with the second trapezoidal blocks on both sides of the filtration box. Finally, the liquid flows back into the rear pipe of the upper connecting pipe through the second guide pipe. This lining process in the magnetic level gauge reduces the size of the central through-hole, preventing blockage caused by impurities in the liquid and ensuring the measurement accuracy and stability of the level gauge.

[0018] 2. This highly stable magnetic float level gauge, by shaking the rocker arm, drives the movable section rod to move. The movable section rod is specifically composed of a connecting rod body, which in turn drives the vertical rod to perform a vertical reciprocating extension and retraction motion. This causes the brush surface on the brush plate to scrape the filter hole surface of the filter screen plate, removing clogging impurities. By pulling the handle upwards, the elastic telescopic rod can be retracted, separating the first trapezoidal block from the second trapezoidal block, thus easily removing the filter screen plate for cleaning or replacement. After cleaning, the filter screen plate is reinstalled, and the snap-fit ​​assembly is ensured to firmly fix it, effectively preventing the filter holes on the filter screen plate from being blocked by impurities.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a highly stable magnetic float level gauge, including a level gauge 1, with an upper pipe 2 and a lower pipe 4 interconnected at the rear of the level gauge 1, and a baffle plate 6 fixedly installed on the inner wall of the upper pipe 2, and a filtration mechanism 3 fixed at the upper end of the upper pipe 2, the filtration mechanism 3 including:

[0027] The filtration assembly 31 is disposed on the upper part of the upper connecting pipe 2, including a filtration box 311 fixed on the upper part of the upper connecting pipe 2, and a first liquid guide pipe 312 and a second liquid guide pipe 313 interconnecting the filtration box 311 and the upper connecting pipe 2. A filtration screen plate 314 is inserted into the filtration box 311, and a handle 315 is fixed to the top of the filtration screen plate 314. A snap-fit ​​assembly 32 is disposed on both sides of the filtration box 311 and the filtration screen plate 314, and is used to snap-fit ​​and fix the filtration box 311 and the filtration screen plate 314. A cleaning assembly 33 is disposed on the filtration box 311 and is used to scrape and clean the filter hole surface of the filtration screen plate 314.

[0028] In this embodiment, the snap-fit ​​assembly 32 includes an L-shaped connecting rod 321 fixed to both sides of the top of the filter screen plate 314, and an elastic telescopic rod 322 fixed to the lower end of the L-shaped connecting rod 321. A first trapezoidal block 323 is fixed to one end of the elastic telescopic rod 322 near the filter box 311, and a second trapezoidal block 324 is fixed to the outer walls of both sides of the filter box 311. By extending and retracting the elastic telescopic rod 322 at the lower end of the L-shaped connecting rod 321, the first trapezoidal block 323 is pushed to snap into the second trapezoidal blocks 324 on both sides of the filter box 311. The main body of the elastic telescopic rod 322 consists of a rod sleeve and a sliding rod inserted into the rod sleeve. The end of the sliding rod is provided with a protrusion connected to a spring, and the other end of the spring is connected to the rod sleeve.

[0029] In this embodiment, the cleaning component 33 includes a mounting rod 333 fixedly installed on the top of the filter box 311, and a rocker arm 334 rotatably mounted on the mounting rod 333. One end of the rocker arm 334 is fixed with a movable section rod 335, and the lower end of the movable section rod 335 is rotatably connected to a vertical rod 331 that penetrates the upper wall of the filter box 311. A brush plate 332 is fixedly installed at the lower end of the vertical rod 331. The brush surface on the brush plate 332 is in contact with the filter hole surface of the filter screen plate 314. By shaking the rocker arm 334, the rocker arm 334 drives the movable section rod 335 to move. The movable section rod 335 is specifically composed of a rod body that is movably connected, thereby driving the vertical rod 331 to perform vertical reciprocating extension and retraction movement, thereby causing the brush surface on the brush plate 332 to scrape the filter hole surface of the filter screen plate 314.

[0030] In this embodiment, the inner walls of both the upper pipe 2 and the lower pipe 4 are fixed with anti-corrosion liners 5, and one side of both the upper pipe 2 and the lower pipe 4 is integrally formed with a flange; the anti-corrosion liners 5 effectively prevent corrosive liquids from eroding the pipe walls and extend the service life of the equipment. In addition, the flange design facilitates the connection and disassembly of the level gauge 1 and the container of the liquid being measured.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the level gauge 1 is connected to the container of the liquid being measured via its upper connecting pipe 2 and lower connecting pipe 4, allowing the liquid to flow freely. When the liquid enters through the upper connecting pipe 2, it first encounters the filtration mechanism 3. The filtration component 31 of the filtration mechanism 3 then begins to operate. The liquid first enters the filtration box 311 through the first guide pipe 312. Inside the filtration box 311, the liquid is filtered by the filtration screen plate 314 to remove impurities. The filtration screen plate 314 is securely installed inside the filtration box 311 via the snap-fit ​​component 32. Specifically, the elastic telescopic rod 322 at the lower end of the L-shaped connecting rod 321 pushes the first trapezoidal block 323 to engage with the second trapezoidal blocks 324 on both sides of the filtration box 311. Finally, the liquid flows back into the rear pipe of the upper connecting pipe 2 through the second guide pipe 313. Furthermore, with prolonged use, the filter holes of the filtration screen plate 314 may become clogged with impurities. In this case... The operator can crank the rocker arm 334, which drives the movable rod 335 to move. The movable rod 335 is specifically composed of a rod body that is connected to the movable joint. This causes the vertical rod 331 to perform a vertical reciprocating extension and retraction movement, thereby causing the brush surface on the brush plate 332 to scrape the filter hole surface of the filter screen plate 314 to remove the clogging impurities. The operator can also pull the handle 315 upward to retract the elastic telescopic rod 322, separating the first trapezoidal block 323 from the second trapezoidal block 324, so as to easily remove the filter screen plate 314 for cleaning or replacement. After cleaning, the filter screen plate 314 is reinstalled, and the snap-fit ​​assembly 32 is made to secure it firmly.

[0033] The purified liquid, after being processed by the filtration mechanism 3, continues to enter the measuring area of ​​the level gauge 1 through the upper pipe 2 for level measurement. Simultaneously, the lower pipe 4 ensures smooth outflow of liquid from the container, maintaining liquid circulation. The anti-corrosion lining 5 on the inner walls of the upper and lower pipes 2 and 4 effectively prevents corrosive liquids from eroding the pipe walls, extending the service life of the equipment. Furthermore, the flange design facilitates the connection and disassembly of the level gauge 1 with the container containing the measured liquid. The entire workflow ensures that the level gauge 1 receives pure, impurity-free liquid during measurement, improving the accuracy and stability of the measurement.
