Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of measuring devices, and in particular relates to a float level gauge for a polymerization reactor. Background Art
[0002] In order to measure the liquid level of the material in the tank, a float level gauge can be installed on the top of the polymerization reactor. The protective sleeve of the float level gauge is only fixed through the flange on the top of the reactor, and the part below the flange of the protective sleeve is suspended in the container. When the float level gauge is working, the protective sleeve and the float are in contact with the material in the container. After the agitator is started, the material will be swung and react. Since the material in the polymerization reactor usually reaches a certain viscosity after the polymerization reaction, the protective sleeve is subjected to great force after the agitator is started, resulting in serious deformation of the protective sleeve. After deformation, the float of the float level gauge is affected and the level gauge will not work properly. In addition, the bent part of the protective sleeve will touch the agitator, making the agitator unusable. Therefore, the float level gauge and the damaged equipment need to be dismantled and repaired. Utility Model Content

[0005] In a preferred embodiment of the present invention, a protective sleeve is provided on the outer periphery of the float level gauge.
[0006] In a preferred embodiment of the present invention, the positioning ring is sleeved on the outer circumference of the protective sleeve and fixed.
[0007] In a preferred embodiment of the present invention, the angle between the two support arms is an acute angle and the two support arms are located in the same horizontal plane of the polymerization reactor, and form a triangular structure with the inner wall of the polymerization reactor.

[0019] Example
[0020] A float level gauge for a polymerization reactor comprises a float level gauge and a bracket; the float level gauge is inserted into the polymerization reactor from top to bottom, and the upper end is fixed by a flange opening on the top of the polymerization reactor; the bracket comprises a positioning ring, the positioning ring is used to sleeve the lower end of the float level gauge, two support arms are welded to the positioning ring, and the two support arms are respectively welded to the inner wall of the polymerization reactor.
[0021] The outer circumference of the float level gauge is provided with a protective sleeve. The positioning ring is sleeved on the outer circumference of the protective sleeve and fixed. During installation, only the lower end of the protective sleeve needs to be directly placed into the positioning ring. The inner diameter of the positioning ring is slightly larger than the outer diameter of the protective sleeve, which facilitates the installation of the protective sleeve of the float level gauge.
[0022] The angle between the two support arms is acute and they are located in the same horizontal plane of the polymerization reactor, and form a triangular structure with the inner wall of the polymerization reactor, so as to prevent the positioning ring from swinging left and right and bending after being stressed, and make the positioning ring more firm and stable.
[0023] Since the polymerization reactor is also provided with an agitator, the agitator is inserted into the reactor along the central axis of the polymerization reactor. A paddle is provided at the bottom of the agitator. Since the paddle is used to stir the reactants, the float level gauge is parallel to the central axis of the polymerization reactor and is usually located above the horizontal plane where the paddle is located. When the material in the reactor is swung after the agitator is started and the protective sleeve is deformed due to force, the protective sleeve is limited by the positioning ring to prevent the protective sleeve from excessive bending and deformation, thereby preventing the protective sleeve from hitting the agitator, making the agitator and the float level gauge run more stably and reducing the frequency of equipment maintenance.
[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
