Description

Technical Field

[0001] This utility model relates to a liquid level measuring instrument, specifically a float level gauge for detecting the high or low position of liquid level in a reaction vessel. Background Technology

[0002] A level gauge is a conventional instrument used to detect the height of liquid levels. It works in conjunction with a display to show the numerical value of the liquid level in a container. Existing level gauges include submersible float level gauges, radar level gauges, rod-type capacitive level gauges, magnetic level gauges, and rod-type float level gauges, each with its own advantages for measuring liquid levels in static storage tanks. However, unlike typical static storage tanks, the conditions inside reaction vessels are often more complex. Depending on the reaction conditions, the vessel may experience high temperatures, high pressures, liquid boiling, rapid stirring and fluctuations, strong corrosiveness, solid crystal adhesion to the walls, and mixing and impact of solid materials, all of which can render traditional level gauges inaccurate.

[0003] in, When there is agitation, the traction rope of the submersible float level gauge will become entangled in the agitator, rendering it unusable. Radar level gauges exhibit significant fluctuations in environments with agitation, leading to inaccurate detection. In high-temperature, high-pressure environments where the liquid is boiling, steam can interfere with the detection signal of radar level gauges and rod-type capacitive level gauges. Magnetic float level gauges are prone to jamming by materials containing solids, leading to malfunction. Top-mounted magnetic float level gauges consist of a connecting pipe, a magnetic float, and a main structure. The hollow interior of the main structure facilitates the placement of the magnetic float, allowing it to rise and fall within the hollow area. The outer side of the main structure features a magnetic flap that flips under the influence of the float, displaying a prominent red or other colored indicator. The connecting pipe connects the interior of the main structure to the interior of a reaction vessel, allowing the liquid level inside the vessel to be reflected in the hollow interior of the main structure. In environments where solids are present or where reactions produce solids, the connecting pipe may become blocked, jamming the float and causing measurement failure. Rod-type float level gauges are prone to material buildup in environments with solids, which increases the weight of the float and causes detection failure. Therefore, a more versatile and accurate level gauge is needed, capable of simultaneously meeting or adapting to the following application scenarios: 1. Resistant to stirring and tangling; 2. Impact resistant; 3. Temperature and pressure resistant, ensuring condensation and reflux of liquid vapor; 4. Adaptable to liquids containing solid materials to prevent material buildup. Utility Model Content

[0004] The purpose of this invention is to provide a float level gauge, and the technical problem to be solved is: how to complete the level detection under the conditions of high temperature, solid particles and stirring.

[0005] The float level gauge includes a motor, gear set, wheel, connecting rod, processor, traction rope, float, sleeve, condenser, and flange. The motor is assembled with the wheel and drives it to rotate, while the motor and gear set are assembled to drive the connecting rod to rotate. The processor senses the rotation of the connecting rod and generates an electrical signal. The traction rope is wound around the wheel and, as the wheel rotates, causes the float at the end of the traction rope to rise or fall. The sleeve is hollow and houses the float and traction rope. The sleeve is vertically fixed below the reactor lid via the flange, and its wall has evenly distributed connecting holes and is open at the bottom. The condenser is arranged above the flange.

[0006] The motor is a servo motor.

[0007] The gear set includes a first gear and a second gear that mesh with each other, with a transmission ratio of 1:1.5-1:5.

[0008] The processor remotely displays the liquid level.

[0009] The traction rope is a metal rope.

[0010] The float is made of 304 or 316L stainless steel and weighs 0.1-2 kg.

[0011] The float is a hollow stainless steel sphere with a clearance fit between its outer diameter and the inner diameter of the sleeve, with a clearance value of 2-5mm.

[0012] The diameter of the connecting hole in the cylinder wall is 1-3 mm.

[0013] The float level gauge also has a sealed housing; the motor, gear set, wheel, connecting rod, processor, and part of the traction rope are arranged inside the sealed housing.

[0014] The beneficial effects of this utility model are: 1. Using a servo motor-driven traction rope instead of a straight rod reduces the weight of the float, allowing for a smaller float volume and reduced draft, thereby reducing the impact of liquid shock on the float. 2. By confining the float entirely within the sleeve, the float is not affected by the stirring of the liquid inside the vessel. At the same time, the sleeve wall has many connecting holes that can connect the liquid and the gas, so there will be no problem of float blockage. 3. It can simultaneously adapt to application scenarios involving high temperature, liquid boiling, rapid stirring and fluctuation, strong corrosion, solid crystal adhesion to the wall, and mixing and impact of solid materials; 4. The sleeve, float and traction rope mentioned above can all be made of stainless steel, which is not easy to wear, has a long service life, requires no maintenance, has low cost and is easy to use.

[0016] Please refer to Figure 1 and Figure 2 The float level gauge shown in the diagram mainly consists of a motor 4, gear set 3, wheel 2, connecting rod 6, processor 5, traction rope 8, float 10, sleeve 9, condenser 11, flange 7, and sealing shell 1. The core design principle is to convert the vertical height of the float 10 into an electrical signal converted by the processor 5. Simultaneously, the sleeve 9 and condenser 11 are configured to improve the working environment of the float 10, thus ensuring that the float level gauge as a whole meets the design requirements. In practical applications, the above components can be further optimized, existing components can be replaced with equivalent ones, or other components can be added as needed.

[0017] The motor 4 in the diagram is a servo motor, which can precisely drive the float 10 up and down via the traction rope 8. The gear set 3 is designed with two gear structures: a meshing driving gear (the first gear 31 in the diagram) and a driven gear (the second gear 32 in the diagram). The driving gear is mounted on the rotating shaft of the motor 4 and rotates synchronously with the shaft, while the driven gear drives the connecting rod 6 to rotate synchronously. These two gears can be designed with different transmission ratios, such as 1:1.5 to 1:5. The drum 2 is a conventional drum-type structure, facilitating the winding of the traction rope 8. The drum 2 is also mounted on the rotating shaft of the motor 4, maintaining synchronous rotation with the shaft. Driven by the servo motor 4, it winds up the traction rope 8, causing the float 10 to rise or fall. The connecting rod 6 is a conventional rod-shaped structure, inserted into the driven wheel and rotating with it, while also facilitating the processor 5 to sense and detect its rotation. The processor 5 is a conventional encoder structure. It records the direction and number of rotations of the connecting rod 6 and converts them into digital signals, which are then displayed remotely for easy observation by the operator.

[0018] The traction rope 8 in the diagram is made of metal and is mainly used to hold the float 10. The float 10 is made of 304 or 316L stainless steel and weighs 0.1-2 kg. The float 10 is a hollow stainless steel sphere with a clearance fit between its outer diameter and the inner diameter of the sleeve 9, with a clearance value of 2-5 mm. Through this design, the float 10 can detect the liquid level in the reactor. The sleeve 9 is made entirely of stainless steel. The sleeve 9 has many small holes (1-3 mm) in its body, which allow liquid and gas to flow through, reducing gas resistance when the liquid rises. A cross beam is designed at the bottom of the sleeve 9 to prevent the float 10 from falling out of the sleeve 9. Through this design, the float 10 is limited and fixed, preventing it from shifting laterally due to the agitation of the liquid. At the same time, the sleeve 9 is vertically fixed to the bottom of the reactor cover by the flange 7.

[0019] To allow the rising hot steam to condense into liquid and return to the vessel, the float level gauge 10 incorporates a condenser 11 structure located above the flange 7. To protect components such as motor 4, gear set 3, wheel 2, connecting rod 6, and processor 5, these components can be placed inside a sealed housing 1.
