AI Technical Summary
When detecting liquid level of high-temperature viscous materials, existing magnet float level meters are prone to appear light components of viscous materials condensation on the outer wall of the magnet float, resulting in narrowing or blocking the inner cavity of the liquid level meter, which cannot work normally, posing a safety hazard.
A magneto-floor level meter for high-temperature viscous materials was designed, and heat tracing was adopted to increase the temperature of the magneto-floor guided inner cavity to prevent the light components of the viscous materials from condensing. At the same time, a high-temperature magnetostrictive liquid level transmitter was used for liquid level detection and transmission, and the on-site and remote display of the liquid level was achieved through a magnetic flip display meter.
It effectively solves the problems of jamming and blockage of the inner cavity of the liquid level meter with high-temperature viscous material, maintains the movement performance of the inner cavity, realizes real-time liquid level monitoring and automatic control, and improves the safety and practical performance of the liquid level meter.

[0016] The following is combined with Figure 1 , 2 The specific implementation methods of the utility model are further described.
[0017] A magnetic float level gauge for high-temperature viscous materials, comprising a tube body 1, the tube body 1 is a hollow cylindrical structure with two ends open, a jacket outlet 4 and a jacket inlet 5 are arranged on the outer wall of the tube body 1, the jacket outlet 4 is located above the jacket inlet 5, a magnetic flap display 6 and a magnetic rod 8 are installed on the outer wall of the tube body 1, the upper and lower ends of the magnetic rod 8 are fixed to the outer wall of the tube body 1 by a fixing strip 11, and the bottom end of the magnetic rod 8 is connected in sequence with a high-temperature isolation bend 9, a high-temperature magnetic induction Telescopic liquid level transmitter 7, inner cylinder 2 is welded inside the tube body 1, jacket 13 is formed between the tube body 1 and inner cylinder 2, inner cylinder 2 is a hollow cylindrical structure with an opening at the bottom, threaded hole is opened in the middle of the top surface of inner cylinder 2, inner cylinder plug 3 is threadedly connected to the top of inner cylinder 2, fixing flange 15 is welded to the bottom of inner cylinder 2, magnetic float 10 is arranged inside inner cylinder 2, connecting rod 12 is connected to the bottom of magnetic float 10, and floating ball 14 is connected to the bottom of connecting rod 12. The material of inner cylinder 2 is stainless steel, and the material of magnetic float 10, connecting rod 12 and floating ball 14 is titanium metal, which has the characteristics of high temperature resistance and high strength, and is particularly suitable for use with high temperature medium materials.
[0018] After the float ball 14 of the level gauge is inserted into the liquid level pipe mouth of the container, the fixing flange 15 can be used to fasten with the container flange to realize the assembly of the level gauge body to the container, and then the required heating medium inlet and outlet pipelines are connected to the jacket outlet 4 and the jacket inlet 5, and the power supply of the high-temperature magnetostrictive liquid level transmitter 7 is turned on and debugged, and the assembly is completed.
[0019] When the heating medium (such as steam, heat transfer oil, etc.) circulates in the jacket 13 of the liquid level gauge, the temperature of the inner cylinder 2 of the liquid level gauge rises to a constant operating temperature. At this time, the light components of the high-temperature material solidified in the inner cavity between the magnetic float 10 and the inner cylinder 2 melt under the action of temperature, and fall into the container under the action of gravity. The lifting and lowering inner cavity channel of the magnetic float 10 will remain unobstructed, and the float 14 will rise and fall by buoyancy under the lifting and lowering of the liquid in the container, and the connecting rod 12 between the float 14 and the magnetic float 10 drives the magnetic float 10 and the float 14 to rise and fall in the same way.
