Description

Technical Field

[0001] This utility model belongs to the field of liquid level measurement technology, specifically relating to a magnetic float liquid level gauge with an anti-self-aggregation device. Background Technology

[0002] A magnetic float level gauge (also known as a magnetic level gauge) is a level measuring instrument based on the principles of buoyancy and magnetic coupling. It features intuitive display, high reliability, and strong adaptability, and is widely used in industrial level monitoring. The working principle of a magnetic float level gauge is as follows: when the liquid level in the measured container rises or falls, the magnetic float in the gauge's main tube also rises or falls accordingly. The permanent magnet inside the magnetic float transmits the signal to the magnetic float indicator via magnetic coupling, driving the flip-plate unit, composed of small red and white flip plates, to rotate 180°, thus displaying the corresponding liquid level height.

[0003] In actual production processes, when the measured medium is a self-polymerizing substance such as butadiene, the medium flowing into the level gauge's main pipe is difficult to circulate and remains stagnant for extended periods, making it prone to self-polymerization. This can cause blockages in the level gauge, leading to its failure and affecting measurement accuracy. Furthermore, it can allow the measured medium to enter connected storage tanks, posing a hazard. Disassembling the level gauge for cleaning and maintenance increases the workload for personnel, and improper operation that allows oxygen to enter the storage tank further increases the risk of self-polymerization of the measured medium.

[0020] Figure 2 This is a schematic diagram of the impeller structure in this utility model. Detailed Implementation

[0021] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] This embodiment proposes a magnetic float level gauge with an anti-self-aggregation device, the overall structure of which is as follows: Figure 1 As shown, it mainly includes a level gauge body pipe 1, an exhaust valve 5, an upper connecting flange 2, a lower connecting flange 3, a magnetic float indicator 4, and a magnetic levitation element 7. The exhaust valve 5 is installed at the top of the level gauge body pipe 1. The upper connecting flange 2 and the lower connecting flange 3 are respectively installed on the bottom of the side wall and the protruding connecting pipe at the top of the level gauge body pipe 1. The magnetic levitation element 7 is installed inside the pipe body of the level gauge body pipe 1, and the magnetic float indicator 4 is installed on the side wall of the level gauge body pipe 1. An anti-self-aggregation device is installed at the bottom of the level gauge body pipe 1.

[0023] The anti-self-agglomeration device includes an impeller working tube located at the bottom of the level gauge body tube 1, the diameter of which is smaller than the diameter of the level gauge body tube 1. The top of the impeller working tube communicates with the bottom of the level gauge body tube 1, and two intersecting impeller fixing rods 8 are provided at the communication point. A stirring impeller 9 is disposed in the impeller working tube and connected to the midpoint of the two impeller fixing rods 8 via a rotating shaft 12. Figure 2 As shown, the stirring impeller 9 consists of four impeller blades 13 inclined in the same direction, and the stirring impeller 9 can rotate freely through the rotating shaft 12.

[0024] A polymerization inhibitor injection point 6 is added at the upper connecting flange 2, allowing for the periodic addition of polymerization inhibitors as needed based on the actual conditions of the device. The polymerization inhibitor mixes with the measured medium in the level gauge body pipe 1. A connecting pipeline and a circulation pump 11, connected to the measured storage tank, are installed at the bottom of the impeller working pipe, forming a circulation pipeline between the level gauge body pipe 1 and the measured storage tank. A discharge valve 10 is installed on the connecting pipeline. Turning on the circulation pump 11 allows the measured medium to be pumped into the measured storage tank. As the solution in the level gauge body pipe 1 decreases, new liquid will be automatically added at the upper connecting flange 2 and the lower connecting flange 3, forming a circulation. Simultaneously, when the measured medium flows through the impeller blades 13, it pushes the impeller blades 13 to drive the stirring impeller 9 to rotate, causing a slight vortex in the liquid in the level gauge body pipe 1, increasing the liquid's fluidity, and further mixing the added polymerization inhibitor with the solution.
